    The left renal vein (LRV) entrapment syndrome is a rare condition. Here, we present a 22-year-old female presenting with recurrent nausea, vomiting, weight loss and evidence of the LRV compression by the superior mesenteric artery and the abdominal aorta. Hemodynamic assessment confirmed a pressure gradient of >3 mmHg between the LRV and the inferior vena cava. A self-expandable stent was then deployed in the LRV. Subsequent clinical follow-ups ensure full resolution of the patient's symptoms. Multilingual search was performed in PubMed, Google scholar, Scielo, Korea Med and EMBASE with the medical subheadings "nutcracker syndrome", "nutcracker phenomenon" and "compression vein syndrome" from January 1983 to September 2013. Review of the literature exhibited a plethora of individual case reports (291 citations). Importantly, few retrospective case series [5] comprising a total of 157 patients included successful endovascular interventions. Endovascular therapy for nutcracker syndrome represents a safe and suitable treatment option, but prospective studies are needed to confirm these data. Copyright © 2014 Elsevier Inc.

    Approximately 6 - 50 % of all ischemic strokes are caused by intracranial arterial stenosis (IAS). Despite medical prevention, patients with symptomatic IAS have a high annual risk for recurrent ischemic stroke of about 12 %, and up to 19 % in the case of high-grade IAS (≥ 70 %). Digital subtraction angiography remains the gold standard for the diagnosis and grading of IAS. However, noninvasive imaging techniques including CT angiography, MR angiography, or transcranial Doppler and duplex ultrasound examinations are used in the clinical routine to provide additional information about the brain structure and hemodynamic. However, for technical reasons, the grading of stenoses is sometimes difficult and inaccurate. To date, aspirin is recommended as the treatment of choice in the prevention of recurrent ischemic stroke in patients with IAS. IAS patients who suffer a recurrent ischemic stroke or transient ischemic attack while taking aspirin can be treated with endovascular stenting or angioplasty in specialized centers. The periprocedural complication rate of these endovascular techniques is about 2 - 7 % at experienced neuro-interventional centers. The rate of re-stenosis is reported between 10 and 40 % depending on patient age and stenosis location. Further randomized studies comparing medical secondary prevention and endovascular therapy are currently being performed. With regard to the improvement of endovascular methods and lower complication rates, the indication for endovascular therapy in IAS could be broadened especially for stenosis in the posterior circulation.

    Rapid endovascular therapy (EVT) is an emerging treatment option for acute ischemic stroke. Several economic evaluations have been published examining the cost-effectiveness of EVT, and many international bodies are currently making adoption decisions. The objective of this study was to establish the cost-effectiveness of EVT for ischemic stroke patients and to synthesize all the publicly available economic literature. A systematic review of the published literature was conducted to identify economic evaluations and cost analyses of EVT for acute ischemic stroke patients. Systematic review best practices were followed, and study quality was assessed. Four-hundred sixty-three articles were identified from electronic databases. After deduplication, abstract review, and full-text review, 17 studies were included. Seven of the studies were cost analyses, and 10 were cost-effectiveness studies. Generally, the cost analyses reported on the cost of the approach/procedure or the hospitalization costs associated with EVT. All of the cost-effectiveness studies reported a cost per quality-adjusted life year as the primary outcomes. Studies varied in regards to the costs considered, the perspective adopted, and the time horizon used. All the studies reported a cost per quality-adjusted life year of <$50 000 as the primary outcome. There is a robust body of evidence for the cost and cost-effectiveness of EVT. The cost analyses suggested that although EVT was associated with higher costs, it also resulted in improved patient outcomes. From the cost-effectiveness studies, EVT seems to be good value for money when a threshold of $50 000 per quality-adjusted life year gained is adopted. © 2017 American Heart Association, Inc.

    Full Text Available Endovascular therapy (EVT has gained vogue in the management of patients with acute stroke. Newer stent-retriever devices have led to better recanalization rates. In many centers, EVT is slowly being used as an add on to or in some instances, even as an alternative to intravenous tissue plasminogen activator (IV tPA. The publication of the results of the SYNTHESIS expansion, Interventional Management of Stroke III and Mechanical Retrieval Recanalization of Stroke Clots Using Embolectomy trials in 2013 has questioned the enthusiastic use of EVT in acute stroke. They demonstrate that EVT (using a variety of devices is no superior to IV tPA in the management of acute stroke. In the light of these controversial findings, we review the current status of EVT in the management of acute stroke.

    Tibioperoneal occlusive disease is one of the most difficult disease processes to successfully treat. Previous studies have attempted to address the outcomes of tibial interventions in this patient population; however, the majority of these study cohorts are composed of patients who have undergone concomitant aortoiliac or femoral procedures. Our objective was to present the outcomes of patients treated with endovascular intervention for isolated below-the-knee atherosclerotic disease causing critical limb ischemia (CLI). We performed a retrospective review of all patients who underwent isolated endovascular treatment of the below-knee popliteal, tibial, and/or peroneal arteries for CLI (Rutherford class 4-6). Primary outcomes include wound healing, reintervention rates, and amputation-free survival out to 5 years, as well as 1-year primary patency rates. 116 patients were identified as having undergone a tibial endovascular intervention. Ninety-two had concomitant aortoiliac or femoropopliteal interventions; after excluding those patients, we identified 24 limbs that were treated for isolated below-knee popliteal, tibial, and/or peroneal occlusive disease using an endovascular modality. 62.5% of limbs had successful wound healing, whereas 37.5% eventually required a major amputation. Mean time to amputation was 514.6 days (standard error: 57.3). Of those patients with successful limb salvage (n = 15), 66.7% required only the index procedure to heal; the remaining 33.3% required a repeat endovascular intervention, an arterial bypass, or a combination to successfully heal. The mean time to reintervention was 780.1 days (standard error: 179.5). The 1-year primary patency rate was 52.6% (n = 19). Patients with CLI secondary to isolated below-the-knee atherosclerotic occlusive disease are a difficult population to successfully treat; despite this, these patients benefit from an initial attempt at endovascular limb salvage. In our experience, this approach

    This report presents a rare case of intestinal infarction following endovascular therapy. A female patient who had undergone an internal carotid artery stenting procedure presented suddenly with abdominal pain. Radiological and clinical examinations at the time suggested a picture of intestinal ischaemia, in view of the patient's general conditions and co-existing morbidities surgical intervention was not considered to be an option. The patient died 4 days after the carotid stenting procedure, post-mortem examination revealed infarction of the ileum and caecum. The learning outcomes are if performing endovascular therapy in a patient with diffuse atherosclerotic disease early consideration of intestinal ischaemia should be given to any patient who presents with acute post-procedural abdominal pain.

    Endovascular stent grafts are intravascular devices composed of surgical graft material and a metallic frame, (Fig. 1). Their main application has been to treat aneurysms, but they have been used in vascular trauma and are being investigated for use in occlusive disease. Their advantage in treating aneurysms over conventional surgical treatment is that they are loaded into relatively small delivery systems (Fig. 2) and can be introduced to the area of interest from a remote site - usually the femoral artery. This avoids the morbidity of surgical exposure in difficult sites, such as the thoracic aorta, and lessens the cardiovascular stress to patients by eliminating the need to surgically cross-clamp the vessel being treated. The first description of abdominal aortic aneurysm exclusion by an endovascular stent graft was provided by Parodi and colleagues in 1991. Much of the early clinical experience in endovascular stent grafting was obtained from centres in Australia and Europe, and they are now reporting midterm follow-up data. There are now many centres in Canada and the United States involved in endovascular research and practice. (author)

    Delayed onset of non-ischemic cerebral enhancing (NICE) lesions is a rare complication of intracranial aneurysms' endovascular therapy (EVT). The purpose of this study is to report this rare complication and its potential pathophysiology in a single-center case series and review the relevant literature. After retrospective review of all patients managed by EVT at our institution from January 1, 2012 to December 31, 2014, 2 out of 374 patients (0.5 %) with such a complication were identified. Skin patch testing was performed with all endovascular devices used in the two patients and with the European baseline series, including nickel. All previously published cases in the English literature were reviewed based on exhaustive PubMed and Embase research. Patient no. 1 developed NICE lesions 1 month after balloon-assisted coiling of a ruptured anterior communicating artery aneurysm. Patient no. 2 developed NICE lesions 12 months (the longest delay reported to date for such a complication) after the treatment of a right carotid-ophthalmic aneurysm by loose coiling and flow diversion. Patient no. 2 demonstrated nickel skin reactivity, but none of the two patients presented allergic reaction to the devices used during interventions. Based on our observations and review of the literature, we hypothesize that delayed non-ischemic cerebral enhancing lesions after EVT are more likely related to foreign body emboli rather than nickel allergy. The two presented cases demonstrate the potential for recurrence and prolonged fluctuation of NICE lesions, warranting long-term follow-up for all patients presenting this complication.

    Aortic wall complications can occur in unrepaired aortic coarctation (CoA) and after surgical repair or endovascular treatment. This review summarizes the available literature and current understanding of aortic wall injury (AWI) surrounding the management of CoA, focusing specifically on acute and follow-up AWI after endovascular treatment. There have been 23 reported cases of aortic rupture after endovascular treatment for CoA, including angioplasty alone, bare metal stenting, and primary covered stent therapy. Even if these published cases represent only a minority of ruptures that have actually occurred, the incidence is substantially treatment of CoA seems to be declining in frequency with increasing experience and improving technology, it remains one of the most important potential adverse outcomes. Long-term surveillance for new AWI and monitoring of existing AWI is mandatory, with institution of appropriate treatment when necessary. A central research focus in this population should be determination of the appropriate treatment for both native and recurrent CoA across various ages with regard to limiting recurrent CoA and preventing associated aortic wall complications, in addition to determining the appropriate treatment of various AWI. Consistent definitions and reporting are necessary to truly understand the incidence of, risk factors for, and measures protective against AWI after angioplasty or stent implantation for CoA. © 2015 American Heart Association, Inc.

    Full Text Available The aim of this study is to compare the effect of conscious sedation (CS with general anesthesia (GA on clinical outcomes in patients with acute ischemic stroke (AIS undergoing endovascular therapy (EVT. MEDLINE, EMBASE, and Cochrane Central Registers of Controlled Trials (from inception to July 2017 were searched for reports on CS and GA of AIS undergoing EVT. Two reviewers assessed the eligibility of the identified studies and extracted data. Data were analyzed using the fixed-effects model, and the sources of heterogeneity were explored by sensitive analysis. Trial sequential analysis was conducted to monitor boundaries for the limitation of global type I error, and GRADE system was demonstrated to evaluate the quality of evidence. A total of thirteen studies were finally identified. Pooled analysis of the incidence of mRS score ≦ 2 after hospital discharge and one or three months in the CS group was higher than that in the GA group. The all-causing mortality of AIS patients in the CS group was lower than that in the GA group. There were no differences in the proportion of IA rtPA and thrombolysis between the two groups. Compared with AIS patients receiving GA, the all-causing mortality in the AIS patients receiving CS was decreased, while incidence of mRS score ≦ 2 at hospital discharge and one or three months was increased.

    The Open versus Endovascular Aneurysm Repair trial is the only randomized controlled trial that is funded by the federal government to evaluate the treatment outcomes of infrarenal abdominal aortic aneurysms. Since the initial publication, multiple post-hoc analyses have become available. This review summarizes these data, focusing on the primary outcome measures (ie, overall survival) and several key secondary outcomes including aneurysm-related death, age consideration, secondary procedures, and endoleaks. Cost-effectiveness of each treatment modality and the limitations of OVER trial also are discussed critically in this review. Copyright © 2017 Elsevier Inc. All rights reserved.

    2016-09-01

    Full Text Available Endovascular therapy for ischemic cerebrovascular diseases has developed rapidly in recent years. The latest clinical trials of acute ischemic stroke have shown promising results with the continued advancement of concepts, techniques, and materials. Mechanical thrombectomy is recommended in the treatment of acute ischemic stroke caused by large vessel occlusion of the anterior circulation, according to the guidelines updated in Europe, USA, and China. The long-term therapeutic efficacy of endovascular stenting for carotid artery stenosis has also been proved noninferior to that of carotid endarterectomy. However, the latest clinical trials have shown that the efficacy of stenting for intracranial artery and vertebral artery stenosis is inferior to that of medical treatment alone, which needs urgent attention through further development and studies.

    Endovascular therapy is increasingly used in acute ischemic stroke treatment and is now considered the gold standard approach for selected patient populations. Prior studies have demonstrated that eventual patient outcomes depend on both patient-specific factors and procedural considerations. However, these factors remain unclear for acute basilar artery occlusion stroke. We sought to determine prognostic factors of good outcome in acute posterior circulation large vessel occlusion strokes treated with endovascular therapy. We reviewed our prospectively collected endovascular databases at 2 US tertiary care academic institutions for patients with acute posterior circulation strokes from September 2005 to September 2015 who had 3-month modified Rankin Scale documented. Baseline characteristics, procedural data, and outcomes were evaluated. A good outcome was defined as a 90-day modified Rankin Scale score of 0 to 2. The association between clinical and procedural parameters and functional outcome was assessed. A total of 214 patients qualified for the study. Smoking status, creatinine levels, baseline National Institutes of Health Stroke Scale score, anesthesia modality (conscious sedation versus general anesthesia), procedural length, and reperfusion status were significantly associated with good outcomes in the univariate analysis. Multivariate logistic regression indicated that only smoking (odds ratio=2.61; 95% confidence interval, 1.23-5.56; P =0.013), low baseline National Institutes of Health Stroke Scale score (odds ratio=1.09; 95% confidence interval, 1.04-1.13; P Stroke Scale score, and successful reperfusion status were associated with good outcome in patients with posterior circulation stroke treated with endovascular therapy. © 2017 American Heart Association, Inc.

    The application of endovascular technology for the emergency treatment of traumatic vascular injuries is a new frontier. This study examines recent nationwide use of endovascular therapy in acute arterial traumatic injuries. This retrospective study used the National Trauma Data Bank (NTDB). Cases with a diagnosis of arterial vascular injury were identified according to the International Classification of Diseases, Ninth Revision, Clinical Modification, and procedure codes for endovascular therapy were selected. A descriptive analysis and multiple regressions were performed to identify variables predictive of outcomes. From 1994 to 2003, 12,732 arterial injuries were identified. Between 1997 (when the first endovascular repair was recorded in the NTDB) and 2003, 7286 open arterial repairs and 281 endovascular repairs were recorded for an overall utilization rate for endovascular procedures of 3.7%. The yearly number of endovascular procedures registered in the NTDB increased 27-fold, from four in 1997 to 107 in 2003. Use of stents substantially increased from 12 in 2000 to 30 in 2003; endograft use increased from one in 2000 to 37 in 2003. Nearly equal numbers of blunt (n = 134) and penetrating (n = 111) injuries were treated. The injury severity score (median, interquartile range [IRQ]) was significantly lower in patients who underwent an endovascular procedure at 13 (IRQ, 9 to 26) for trauma vs patients requiring an open procedure at 20 (IRQ, 10 to 34; P undergoing endovascular repair (8.7 +/- 7.2 vs 13.0 +/- 16.1, P undergoing endovascular procedures (odds ratio, 0.18; P = .029) including those with an arterial injury of the torso or head and neck (odds ratio, 0.51, P = .007). Total length of hospital stay also tended to be lower for patients undergoing endovascular procedures by 18% (P = .064). The use of endovascular therapy in the setting of acute trauma is increasing in a dramatic fashion and is being used to treat a wide variety of vessels injured by blunt

    The rapid evolution of endovascular surgery has greatly expanded management options for a wide variety of vascular diseases. Endovascular therapy provides a less invasive alternative to open surgery for critically ill patients who have sustained arterial injuries. The purpose of this study was to evaluate recent trends in the management of arterial injuries in the United States with specific reference to the use of endovascular strategies and to examine the outcomes of endovascular vs open therapy for the treatment of civilian arterial traumatic injuries. A 9-year analysis of the National Trauma Data Bank was performed to identify all patients who sustained arterial injuries. Demographics, clinical data, interventions, and outcomes were extracted. Propensity scores were used to match endovascular patients to those undergoing open operation. Patient outcomes were compared according to treatment approach. A total of 23,105 patients were available for analysis. Overall, there was a significant increase in the use of endovascular procedures during 9 years (from 0.3% in 2002 to 9.0% in 2010; P trauma patients (from 0.4% in 2002 to 13.2% in 2010; P trauma (42.9% in 2002 to 35.8% in 2010; P trauma patients.

    Introduction/objective: Modern practice in Radiology has rapidly changed over the last decades incorporating invasive techniques. Additionally, litigation in medical practice has arisen as an important issue. This article aims to highlight issues related to malpractice in interventional radiology and endovascular therapy in order to point out the importance of the written informed consent. Methods and material: Search of relevant literature from the Pubmed. Results: The role of radiologist has been greatly transformed over the last decades. He is not only entitled to participate in the diagnosis but also he undertakes therapeutic procedures, either alone or as a member of a team. Thus the radiologist is now more exposed to actions that maximize litigation risk. Adequate communication and a written consent form seem to be mandatory before any invasive radiological procedure. Patient should know in detail the benefits and the risks of the scheduled procedure and whether the proposed therapy is a new form of treatment or part of a randomized trial. Discussions and conclusion: Interventional radiologist or physician is exposed to high litigation risk. This certainly requires an urgent adaptation of his practice and attitude to the new reality. Written patient's informed consent remains an integral part of the communication between physicians and patients, and importantly is offering professional protection along these lines.

    The metrics of imaging-to-puncture and imaging-to-reperfusion were recently found to be associated with the clinical outcomes of endovascular thrombectomy for acute ischemic stroke. However, measures for improving workflow within hospitals to achieve better timing results are largely unexplored for endovascular therapy. The aim of this study was to examine our experience with a novel smartphone application developed in house to improve our timing metrics for endovascular treatment. We developed an encrypted smartphone application connecting all stroke team members to expedite conversations and to provide synchronized real-time updates on the time window from stroke onset to imaging and to puncture. The effects of the application on the timing of endovascular therapy were evaluated with a secondary analysis of our single-center cohort. Our primary outcome was imaging-to-puncture time. We assessed the outcomes with nonparametric tests of statistical significance. Forty-five patients met our criteria for analysis among 66 consecutive patients with acute ischemic stroke who received endovascular therapy at our institution. After the implementation of the smartphone application, imaging-to-puncture time was significantly reduced (preapplication median time, 127 minutes; postapplication time, 69 minutes; P smartphone applications may reduce treatment times for endovascular therapy in acute ischemic stroke. Further studies are needed to confirm our findings. Copyright © 2017. Published by Elsevier Inc.

    Therapy of abdominal aortic aneurysms (AAA) is currently based on a high level of evidence. This is not true in the same manner for iliac artery aneurysms (IAA) which are frequently associated with AAAs and occur only rarely as isolated lesions. The therapeutic principles apply in the same way to both aneurysm locations. New findings, improved perioperative care and the rapid development of minimally invasive techniques require a constant update which is the aim of this article concerning the therapy of AAAs and IAAs. A systematic literature review was performed in PubMed and Medline and priority was given to recent publications with a high level of evidence. Endovascular aneurysm repair (EVAR) and open aneurysm repair (OAR) result in a similar long-term survival. The perioperative survival advantage with EVAR persists only during medium-term postoperative courses. The reintervention rate after EVAR is substantially higher compared to OAR. For older patients and those who are considered unfit for OAR the expected benefits from EVAR has not been proven to date. Aneurysmal ruptures after EVAR demonstrate that a life-long surveillance of these patients is necessary. Therapy of AAAs and IAAs is increasingly being performed by EVAR. Even the majority of complex aneurysms are amenable to minimally invasive treatment. Nevertheless, indications for OAR continue to exist. Screening for AAAs results in a decrease of aneurysmal ruptures for which EVAR is also gaining importance.

    We report a case of an iatrogenic arteriovenous fistula complicated by catheter- directed thrombolytic therapy in a patient with acute deep vein thrombosis of a lower extremity. To the best of our knowledge, this is the first report of an arteriovenous fistula between the sural artery and popliteal vein in that situation. As the vessels have a close anatomical relationship, the arteriovenous fistula seems to be a potential complication after endovascular thrombolytic therapy of acute deep vein thrombosis.

    The purpose of this paper is to collect and summarize the clinical evidence related to the endovascular therapy of chronic mesenteric ischemia. The relevant medical literature in English language were collected through Medline by inputting the subject headings, including 'mesenteric ischemia', 'balloon angioplasty', 'mesenteric stenting' and 'intestinal angina'. The medical documents which reported five or more cases receiving endovascular therapy were enrolled in our study for analysis. A total of 16 series with 328 cases altogether were thus obtained. The therapeutic indication for endovascular intervention in all patients was symptomatic mesenteric arterial stenosis. The technical successful rate was 91%. In 75% patients, the clinical symptoms disappeared after the procedure and repeated intervention was not needed. During the follow-up period, re-stenosis occurred in 28% patients. Complications developed in 9% patients, including dissection, distal embolus, infection, thrombosis, bleeding at puncture site, etc. The mortality at 30 days was 3%. Endovascular intervention is a safe treatment for chronic mesenteric stenosis or occlusion. Stent implantation technique carries a higher technical successful rate. However, there are still about one third patients who will probably develop re-stenosis. (authors)

    Full Text Available The "drip and ship" approach can facilitate an early initiation of intravenous thrombolysis (IVT for acute ischemic stroke (AIS at community hospitals. New endovascular treatment modalities, such as stent retrieval, have further improved the rate of safe and successful recanalization. We assessed the clinical outcomes of on-demand endovascular therapy in patients with AIS who were transported to a comprehensive stroke center under the "drip and ship" paradigm.This retrospective study evaluated prospectively registered patients with acute large vessel occlusions in the anterior circulation who underwent endovascular recanalization after IVT at our regional comprehensive stroke center between January 2011 and April 2014. Clinical outcomes and neuroradiological findings were compared between patients who received IVT at the center (direct visit, DV and at a community hospital (drip and ship, DS.Baseline characteristics such as age, initial National Institutes of Health Stroke Scale (NIHSS score, and risk factors for stroke were similar, and most patients underwent endovascular therapy with a Solitaire stent (81.9% vs. 89.3% for DV and DS, respectively, P = 0.55. The average initial NIHSS score was 12.15 ± 4.1 (12.06 vs. 12.39 for DV and DS, respectively, P = 0.719. The proportions of long-term favorable outcomes (modified Rankin Scale score ≤ 2 at 90 days and successful recanalization (Thrombolysis in Cerebral Ischemia score ≥ 2b were not significantly different (P = 0.828 and 0.158, respectively. The mortality rates and occurrences of symptomatic intracerebral hemorrhage were not significantly different (P = 0.999 and 0.267, respectively.The "drip and ship" approach with subsequent endovascular therapy is a feasible treatment concept for patients with acute large vessel occlusion in the anterior circulation that could help improve clinical outcomes in patients with AIS.

    We report our experience in using Guglielmi electrolytically detachable coils (GDC) alone or in combination with other materials in the treatment of intracranial or cervical high-flow fistulae. We treated 14 patients with arteriovenous fistulae on brain-supplying vessels - three involving the external carotid or the vertebral artery, five the cavernous sinus and six the dural sinuses - by endovascular occlusion using electrolytically detachable platinum coils. The fistula was caused by trauma in six cases. In one case Ehlers-Danlos syndrome was the underlying disease, and in the remaining seven cases no aetiology could be found. Fistulae of the external carotid and vertebral arteries and caroticocavernous fistulae were reached via the transarterial route, while in all dural fistulae a combined transarterial-transvenous approach was chosen. All fistulae were treated using electrolytically detachable coils. While small fistulae could be occluded with electrolytically detachable coils alone, large fistulae were treated by using coils to build a stable basket for other types of coil or balloons. In 11 of the 14 patients, endovascular treatment resulted in complete occlusion of the fistula; in the remaining three occlusion was subtotal. Symptoms and signs were completely abolished by this treatment in 12 patients and reduced in 2. On clinical and neuroradiological follow-up (mean 16 months) no reappearance of symptoms was recorded.

    Clinical outcomes after successful endovascular therapy in patients with acute ischemic stroke are associated with several factors including onset-to-reperfusion time (ORT), the National Institute of Health Stroke Scale (NIHSS) score, and the Alberta Stroke Program Early CT Score (ASPECTS). The NIHSS-time score, calculated as follows: [NIHSS score] × [onset-to-treatment time (h)] or [NIHSS score] × [ORT (h)], has been reported to predict clinical outcomes after intravenous recombinant tissue plasminogen activator therapy and endovascular therapy for acute stroke. The objective of the current study was to assess whether the combination of the ASPECTS and the ORT can predict the outcomes after endovascular therapy. The charts of 117 consecutive ischemic stroke patients with successful reperfusion after endovascular therapy were retrospectively reviewed. We analyzed the association of ORT, ASPECTS, and ASPECTS-time score with clinical outcome. ASPECTS-time score was calculated as follows: [11 - ASPECTS] × [ORT (h)]. Rates of good outcome for patients with ASPECTS-time scores of tertile values, scores 5.67 or less, scores greater than 5.67 to 10.40 or less, and scores greater than 10.40, were 66.7%, 56.4%, and 33.3%, respectively (P < .05). Ordinal logistic regression analysis showed that the ASPECTS-time score (per category increase) was an independent predictor for better outcome (common odds ratio: .374; 95% confidence interval: .150-0.930; P < .05). A lower ASPECTS-time score may predict better clinical outcomes after endovascular treatment. Copyright © 2018 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Collaterals sustain the ischemic penumbra to limit growth of the infarct core before revascularization, yet the impact of baseline collateral flow on hemorrhagic transformation (HT) after endovascular therapy remains unknown. A collaborative study from 2 stroke centers in distinct geographic regions included 222 consecutive patients who received endovascular therapy for acute cerebral ischemia. The influence of collaterals on HT was analyzed in distinct case scenarios relative to baseline collateral grade at angiography (0 to 1 versus 2 to 4) and recanalization (Thrombolysis in Myocardial Ischemia scale, 0 to 1 versus 2 to 3): good collaterals and successful recanalization (n=98), poor collaterals with successful recanalization (n=43), good collaterals and no recanalization(n=46), and poor collaterals and no recanalization (n=35). HT after endovascular therapy occurred in 103 (46.4%) patients; 42 (18.9%) were symptomatic. HT was more frequently observed in patients with poor collaterals and recanalization than in other groups (P=0.048). When revascularization was achieved, patients with poorer collaterals were more likely to have symptomatic worsening with HT (r=-0.181, P=0.032). Multiple logistic regression analysis identified aggressive treatment (OR, 2.558 for Merci clot retrieval; 95% CI, 1.153 to 5.678; OR, 3.618 for combined fibrinolytics and mechanical therapy; 95% CI, 1.551 to 8.437; and OR, 2.085 for intravenous thrombolysis before endovascular therapy; 95% CI, 1.096 to 3.969), poor collaterals and recanalization (OR, 2.666; 95% CI, 1.163 to 6.113), and serum glucose levels (OR, 1.007; 95% CI, 1.000 to 1.014) as independent predictors of HT. Angiographic grade of collateral flow strongly influences the rate of HT after therapeutic recanalization for acute ischemic stroke. Collateral status readily available from baseline angiography may therefore refine therapeutic decision-making in acute cerebral ischemia.

    Dural cavernous sinus fistulas (DCSFs) represent a benign vascular disease, consisting in an arteriovenous shunt at the cavernous sinus. In the absence of spontaneous resolution, the fistula may lead to eye redness, swelling, proptosis, chemosis, ophthalmoplegia and visual loss. Although modern imaging techniques have improved the diagnostic, patients with low-flow DCSFs are still misdiagnosed. These patients can get erroneously treated for infections and inflammation for months or years and are at risk of visual loss. Early and proper diagnosis helps to avoid deleterious clinical course of the disease. This volume provides a complete guide to clinical and radiological diagnosis as well as to therapeutic management of DCSF with emphasis on modern minimal invasive treatment options. It commences with an informative description of relevant anatomy. After sections on the classification, etiology and pathogenesis of DCSF, the clinical symptomatology of the disease is described in detail. The role of modern non-invasive imaging tools is then addressed with the use of computed tomography, magnetic resonance imaging and ultrasound. Intra-arterial digital subtraction angiography (DSA), although invasive, remains the gold standard and is mandatory for clinical decision-making and strategy in endovascular treatment. Hence, a throughout consideration is given to both, 2D-DSA and 3D rotational angiography, including recent technological advancements such as Dual Volume (DV) imaging and angiographic computed tomography (ACT). After a short section on arteriovenous hemodynamics, the therapeutic management of DCSFs is described in detail. In particular, various transvenous techniques, required for successful endovascular occlusion of DCSF, are discussed in depth. This well-illustrated volume will be invaluable to all who may encounter DCSF in their clinical practice. (orig.)

    Recent randomized trials have consistently demonstrated a clinical benefit of endovascular therapy (ET) over best medical therapy (including intravenous (IV) thrombolysis in eligible patients) or IV thrombolysis only in selected patients with acute ischemic stroke (AIS) due to proximal occlusion in the carotid territory. Previous study demonstrates that lack of improvement (LOI) at 24 hours is an independent predictor of poor outcome and death at 3 months in patients with AIS treated with IV alteplase. However, LOI at 24 hours following ET has not been studied systematically. The purpose of this study is to identify predictors of LOI at 24 hours in patients with AIS after ET as well as the relationship between LOI and unfavorable outcome at 3 months. A total of 98 consecutive patients with AIS treated with ET in two separate stroke centers from 2010 to 2014 were retrospectively reviewed. Data on demographics, preexisting vascular risk factors, occlusion site, pre- and post-treatment modified Treatment in Cerebral Ischemia (mTICI) classification, collaterals and National Institutes of Health Stroke Scale (NIHSS) score on admission as well as 24 hours after the endovascular procedurals were collected. LOI was defined as a reduction of 3 points or less on the NIHSS at 24 hours compared with baseline. A 3-month functional outcome was assessed using the modified Rankin scale (mRS). Unfavorable outcome was prespecified as a score of more than 2 on the mRS. The onset-to-reperfusion time (ORT) was defined as time to mTICI 2b or 3 or end of procedure. Long ORT was defined as time to reperfusion beyond 6 hours. Poor reperfusion was defined as mTICI ≦2a. The pretreatment collateral circulation extent was graded as poor (grades 0-1) or good (grades 2-4). Among the 98 patients with AIS who were treated with ET, LOI was present in 48 (49%) subjects. Multivariate analysis indicated that poor collaterals (odds ratio [OR] 3.25; 95% confidence interval [CI]: 1.29-8.19; p = 0

    A case of verbro-vertebral fistula in a patient with neurofibromatosis is presented with emphasis on magnetic resonance (MR) evaluation and integration with endovascular therapy. Vascular involvement is a known complication of neurofibromatosis ranging from intimal proliferation causing arterial narrowing, development of small aneurysms, to spontaneous fistulas probably secondary to mesodermal dysplasia. This case report illustrates the latter and portrays a role for MR in diagnosis and follow-up during therapeutic measures. (author). 14 refs.; 3 figs

    PurposeTo evaluate endovascular therapy (EVT) as the primary revascularization method for acute mesenteric ischemia (AMI).MethodsA retrospective review was performed on all consecutive patients treated for AMI during a 5-year period (January 2009 to December 2013). EVT was attempted in all patients referred for emergent revascularization. Surgical revascularization was performed selectively after failure of EVT. Patient characteristics, clinical presentation, and outcomes were studied. Failures and complications of EVT were recorded.ResultsFifty patients, aged 79 ± 9 years (mean ± SD), out of 66 consecutive patients with AMI secondary to embolic or thrombotic obstruction of the superior mesenteric artery were referred for revascularization. The etiology of AMI was embolism in 18 (36 %) and thrombosis in 32 (64 %) patients. EVT was technically successful in 44 (88 %) patients. Mortality after successful or failed EVT was 32 %. The rates of emergency laparotomy, bowel resection, and EVT-related complication were 40, 34, and 10 %, respectively. Three out of six patients with failure of EVT were treated with surgical bypass. EVT failure did not significantly affect survival.ConclusionsEVT is feasible in most cases of AMI, with favorable patient outcome and acceptable complication rate.

    Objective: To discuss the nursing strategy and practical measures for patients with ruptured abdominal aortic aneurysm during the perioperative period of endovascular intervention. Methods: Endovascular therapy was carried out in 34 patients with ruptured abdominal aortic aneurysm,who were encountered in our department during the period of July 1997 to September 2008. The clinical data were retrospectively analyzed and the nursing points were summarized. Results: The average hospitalization days of the 34 patients were (14 ± 5) days, the mortality rate within 30 days was 23.5% (8/34). No nursing-related complications occurred. Conclusion: A comprehensive understanding of the mechanism, development and clinical evolution of ruptured abdominal aortic aneurysm is very important for nursing care. For nursing staff, well mastering the relevant nursing technique, carefully guarding against any nursing errors and lessening patient's suffering as far as possible, all these are the task of primary importance.

    Endovascular reperfusion techniques are a promising intervention for acute ischemic stroke (AIS). Prior studies have identified markers of initial injury (arrival NIH stroke scale (NIHSS) or infarct volume) as predictive of outcome after these procedures. We sought to define the role of collateral flow at the time of presentation in determining the extent of initial ischemic injury and its influence on final outcome. Demographic, clinical, laboratory, and radiographic data were prospectively collected on a consecutive cohort of patients who received endovascular therapy for acute cerebral ischemia at a single tertiary referral center from September 2004 to August 2010. Higher collateral grade as assessed by the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) grading scheme on angiography at the time of presentation was associated with improved reperfusion rates after endovascular intervention, decreased post-procedural hemorrhage, smaller infarcts on presentation and discharge, as well as improved neurological function on arrival to the hospital, discharge, and 90 days later. Patients matched by vessel occlusion, age, and time of onset demonstrated smaller strokes on presentation and better functional and radiographic outcome if found to have superior collateral flow. In multivariate analysis, lower collateral grade independently predicted higher NIHSS on arrival. Improved collateral flow in patients with AIS undergoing endovascular therapy was associated with improved radiographic and clinical outcomes. Independent of age, vessel occlusion and time, in patients with comparable ischemic burdens, changes in collateral grade alone led to significant differences in initial stroke severity as well as ultimate clinical outcome.

    Aortic dissection is a cardiovascular event of high mortality if not early diagnosed and properly treated. In Stanford type A aortic dissection, there is the involvement of the ascending aorta, whereas in type B the ascending aorta is not affected. The treatment of type A aortic dissection is mainly surgical. The hospital mortality of type B aortic dissection surgical treatment is approximately 20%, while medical therapy is 10%. However, half the patients who are discharged from hospital after medical treatment, progress to aortic complications in the following years, and the mortality in three to five years may reach 25-50%. In addition, the surgical treatment of aortic complications after medical treatment, has also a significant mortality. This way, the endovascular treatment comes up as an interesting alternative of a less invasive treatment for this disease. They presented a mortality rate lower than 10% with more than 80% success rate of occlusion and thrombosis of the false lumen. The INSTEAD TRIAL, which randomized patients with uncomplicated type B aortic dissection for optimal medical therapy and endovascular treatment in addition to optimal medical therapy, showed that after three years of follow up, patients who underwent endovascular treatment had lower mortality and aorta-related complications. Therefore, there is a current tendency to recommend the endovascular treatment as a standard for the treatment of type B aortic dissection PMID:25372915

    We evaluated midterm functional outcome after endovascular occlusion of aneurysms in patients with subarachnoid haemorrhage (SAH) and determined the incidence of late rebleeding as an additional prognostic parameter. We treated 79 consecutive patients with SAH from an intracranial aneurysm admitted from a neurological intensive care unit by the endovascular route between 1993 and 1997 and 52 survivors were followed up in 1999-2000. The mean interval between SAH and follow-up was 41 months (range 13-74 months). Outcome was determined by the Glasgow outcome (GOS) and Rankin (RS) scales and by questions concerning neuropsychological disorders. The patients were analysed according to Hunt and Hess (H and H) grades I-III or IV-V on admission. We observed two episodes of rebleeding (3%) with impact on outcome at 907 and 2010 days after SAH, respectively. A complete recovery (GOS 5) was achieved in 53% of H and H grade I-III and 17% of grade IV-V patients; with death rates 19% and 50%, and morbidity according to the RS (5-2) 18% and 29%, respectively. Midterm morbidity after endovascular therapy is thus low. Rebleeding with an impact on outcome can be observed up to 2010 days after SAH, suggesting that long-term angiographic follow-up is indispensable. (orig.)

    Full Text Available Endovascular therapy (EVT has gained vogue in the management of patients with acute stroke. Newer stent-retriever devices have led to better recanalization rates. In many centers, EVT is slowly being used as an add on to or in some instances, even as an alternative to intravenous tissue plasminogen activator (IV tPA. The publication of the results of the SYNTHESIS expansion, Interventional Management of Stroke III and Mechanical Retrieval Recanalization of Stroke Clots Using Embolectomy trials in 2013 has questioned the enthusiastic use of EVT in acute stroke. They demonstrate that EVT (using a variety of devices is no superior to IV tPA in the management of acute stroke. In the light of these controversial findings, we review the current status of EVT in the management of acute stroke.

    Despite major advances in pharmacologic and endovascular therapies, acute limb ischemia (ALI) continues to result in significant morbidity and mortality. The incidence of ALI may be as high as 13-17 cases per 100,000 people per year, with mortality rates approaching 18% in some series. This review will address the contemporary endovascular management of ALI encompassing pharmacologic and percutaneous interventional treatment strategies.

    Endovascular therapy after acute ischemic stroke due to large vessel occlusion is now standard of care. There is equipoise as to what kind of anesthesia patients should receive during the procedure. Observational studies suggest that general anesthesia is associated with worse outcomes compared to conscious sedation. However, the findings may have been biased. Randomized clinical trials are needed to determine whether the choice of anesthesia may influence outcome. The objective of GOLIATH (General or Local Anestesia in Intra Arterial Therapy) is to examine whether the choice of anesthetic regime during endovascular therapy for acute ischemic stroke influence patient outcome. Our hypothesis is that that conscious sedation is associated with less infarct growth and better functional outcome. GOLIATH is an investigator-initiated, single-center, randomized study. Patients with acute ischemic stroke, scheduled for endovascular therapy, are randomized to receive either general anesthesia or conscious sedation. The primary outcome measure is infarct growth after 48-72 h (determined by serial diffusion-weighted magnetic resonance imaging). Secondary outcomes include 90-day modified Rankin Scale score, time parameters, blood pressure variables, use of vasopressors, procedural and anesthetic complications, success of revascularization, radiation dose, and amount of contrast media. Choice of anesthesia may influence outcome in acute ischemic stroke patients undergoing endovascular therapy. The results from this study may guide future decisions regarding the optimal anesthetic regime for endovascular therapy. In addition, this study may provide preliminary data for a multicenter randomized trial. © 2016 World Stroke Organization.

    Transjugular intrahepatic portosystemic shunt (TIPS) has evolved as an effective intervention for treatment of complications of portal hypertension. The use of polytetrafluoroethylene-covered stents have improved the patency of the shunts and diminished the incidence of TIPS dysfunction. However, TIPS-related refractory hepatic encephalopathy (rHE) poses a significant challenge. Approximately 3–7 % of patients with TIPS develop rHE. Refractory hepatic encephalopathy is defined as a recurrent or persistent encephalopathy despite appropriate medical treatment. Hepatic encephalopathy can be an extremely debilitating complication that profoundly affects quality of life. The approach to management of patients with rHE is complex and typically requires collaboration between different specialties. Liver transplantation is the ultimate treatment for rHE; however, the ongoing shortage of organ donation markedly limits this treatment option. Alternative therapies such as shunt occlusion or reduction can control symptoms and serve as a ‘bridge’ therapy to liver transplantation. Therefore, interventional radiologists play a key role in the management of these patients by offering a variety of endovascular techniques. The purpose of this review is to highlight some of these endovascular techniques and to develop a therapeutic algorithm that can be applied in clinical practice for the management of rHE.

    Full Text Available Background. Acute Ischemic Stroke (AIS is a common cause of death worldwide and the leading cause of long-term severe disability. Endovascular bridging therapies (EBT, including endovascular thrombectomy (ET and intra-arterial thrombolytic (IAT, have been recommended to realize a favorable functional outcome for AIS patients. Methods. An overview of meta-analyses of primary randomized controlled trial (RCT studies was performed evaluating EBT for AIS patients compared with usual care. Results. Ten meta-analyses were included in this overview. ET was associated with a higher incidence of achieving functional outcome improvement, defined as a modified Rankin scale of 0 to 1 (mRS, p=0.003, 0 to 2 (p<0.00001, and 0 to 3 (p=0.005. The risk of symptomatic intracranial hemorrhage (sICH rate and all-cause mortality were similar between the two groups. Moreover, IAT treatment was also related to significantly improved outcomes in terms of the mRS score (p<0.05, but no significant difference in rates of sICH and mortality within 90 days. Conclusions. In conclusion, our analysis supports that EBT, regardless of format (e.g., ET or IAT, is superior to the best medical therapy alone (e.g., IVT in terms of mRS score in patients with AIS. In addition, the safety of EBT is similar to IVT.

    Several scales have been proposed for risk assessment and outcome determination in brain arteriovenous malformations treated by endovascular therapy. We aim to validate and compare the efficacy of these scales in predicting perioperative complications and clinical outcomes. We retrospectively reviewed brain arteriovenous malformations patients who underwent endovascular therapy at 4 centers in China from January 2012 to December 2015. The primary outcomes were complications, unfavorable outcome (mRS ≥ 3), and complete obliteration. Each patient was assessed using the Spetzler-Martin grading system (SM), Puerto Rico scale, Buffalo score, and arteriovenous malformation embocure score (AVMES). Correlation analysis was performed between primary outcomes incidence rate and the grades of each scale. The area under the receiver operating characteristic curve of these scales was calculated. Pairwise comparison of receiver operating characteristic curves was performed to compare the efficacy of the scales. A total of 270 patients were included. Correlation analysis demonstrated that the complication rate increased with increasing grade in SM (P = 0.002), Puerto Rico scale (P = 0.014), and Buffalo score (P = 0.001); complete obliteration rate decreased with increasing grade in AVMES (P = 0.017); unfavorable outcome rate increased with increasing grade in the Puerto Rico scale (P = 0.005). The area under the receiver operating characteristic curve analysis showed statistical differences between the Puerto Rico score and SM (P = 0.047) in predicting complications and between the Puerto Rico score and SM (P = 0.008) in predicting unfavorable outcomes. The area under the curve of the AVMES in predicting complete obliteration was 0.757. The Puerto Rico score predicts complications and unfavorable outcomes better than the SM. The AVMES scale has medium efficacy in predicting complete obliteration. Copyright © 2017 Elsevier Inc. All rights reserved.

    Paraclinoid aneurysms have been increasingly treated endovascularly. The natural history of these aneurysms has gradually been elucidated. The purpose of this study was to assess the safety and efficacy of endovascular treatment for these aneurysms. We performed a retrospective review of 377 patients with 400 paraclinoid aneurysms treated between January 2006 and December 2012. Their clinical records, endovascular reports, and radiologic and clinical outcomes were analyzed. Because aneurysms ≥7 mm are at higher risk of rupture, we classified aneurysms as small (<7 mm) or large (≥7 mm). Overall, 115 of the 400 aneurysms (28.8%) were large (≥7 mm). Thromboembolic complications were found significantly more often with large aneurysms than with small ones (7.4% vs 1.0%, P = .001). Hemorrhagic complications were found only with small aneurysms (0.7%). The 6-month morbidity rates were similar for small (1.0%) and large (0.8%) aneurysms. Immediate angiographic outcomes were similar (P = .37), whereas recurrences and retreatment occurred more frequently with large aneurysms (P = .001 and P = .007, respectively). Multivariate analysis showed that aneurysm size was the only independent predictor for recurrence (P = .005). Most recurrences (81%) were detected by scheduled angiography at 6 months. Aneurysm size influenced the type of complication (thromboembolic or hemorrhagic) and the recurrence rate. Given the approximately 1% annual rupture rate for aneurysms ≥7 mm, analysis of our data supports the rationale of using prophylactic endovascular treatment for unruptured paraclinoid aneurysms ≥7 mm. © 2016 by American Journal of Neuroradiology.

    To describe how to make a swine hemodialysis fistula model and report our initial experience to test the feasibility of endovascular radiation therapy with Holmium-166 filled balloon catheters. The surgical formation of arterio-venous fistula (AVF) was performed by end-to-side anastomosis of the bilateral jugular vein and carotid artery of 6 pigs. After 4 weeks, angiograms were taken and endovascular radiation was delivered to the venous side of AVF with Holmium-166 filled balloon catheters. Pigs were sacrificed 4 weeks after the radiation and AVFs were harvested for histological examination. All animals survived without any morbidity during the experimental periods. The formation of fistula on the sides of necks was successful in 11 of the 12 pigs (92%). One AVF failed from the small jugular vein. On angiograms, 4 of the 11 AVFs showed total occlusion or significant stenosis and therefore, endovascular radiation could not be performed. Of 7 eligible AVFs, five underwent successful endovascular radiation and two AVFs did not undergo radiation for the control. Upon histologic analysis, one non-radiated AVF showed total occlusion and others showed intimal thickening from the neointimal hyperplasia. Formation of the swine carotid artery-jugular vein hemodialysis fistula model was successful. Endovascular radiation using a Holmium-166 filled balloon catheter was safe and feasible.

    Purpose. To evaluate the efficacy and safety of endovascular therapy in oral hemorrhage from malignant head and neck tumors. Methods. Ten patients (mean age 56 years) with oral hemorrhage caused by malignant head and neck tumors underwent a total of 13 emergency embolization procedures using gelatin sponge particles, steel and/or platinum coils, or a combination of these embolic materials. Angiographic abnormalities, technical success rate, clinical success rate, recurrence rate, complications, hemostatic period, hospital days, survival days, and patient outcome were all analyzed. Results. Angiographic abnormalities were identified during 85% of procedures (11/13). The technical success rate was 100% (13/13 procedures). The primary and secondary clinical success rates were 77% (10/13 procedures) and 67% (2/3 procedures), respectively. The overall clinical success rate was 92%, and the recurrence rate was 22% (2/9 procedures) in patients whom we were able to observe during the 1-month period after embolization. No major complications occurred. Several patients in whom gelatin sponge particles had been used complained of transient local pain after the procedure. The median hemostatic period was 71 days (range 0-518 days). Median hospital and survival days were 59 days (range 3-209 days) and 141 days (range 4-518 days), respectively. Three patients survived and 7 patients died during the observation period. Only 1 of these 7 patients died from hemorrhage. Conclusion. In conclusion, our findings suggest that endovascular therapy is an effective, safe, and repeatable treatment for oral hemorrhage caused by malignant head and neck tumors

    Purpose: To identify factors impacting outcome in patients undergoing interventions for acute ischemic stroke (AIS). Materials and Methods: This was a retrospective analysis of patients undergoing endovascular therapy for AIS secondary during a 30 month period. Outcome was based on modified Rankin score at 3- to 6-month follow-up. Recanalization was defined as Thrombolysis in myocardial infarction score 2 to 3. Collaterals were graded based on pial circulation from the anterior cerebral artery either from an ipsilateral injection in cases of middle cerebral artery (MCA) occlusion or contralateral injection for internal carotid artery terminus (ICA) occlusion as follows: no collaterals (grade 0), some collaterals with retrograde opacification of the distal MCA territory (grade 1), and good collaterals with filling of the proximal MCA (M2) branches or retrograde opacification up to the occlusion site (grade 2). Occlusion site was divided into group 1 (ICA), group 2 (MCA with or without contiguous M2 involvement), and group 3 (isolated M2 or M3 branch occlusion). Results: A total of 89 patients were studied. Median age and National Institutes of health stroke scale (NIHSS) score was 71 and 15 years, respectively. Favorable outcome was seen in 49.4% of patients and mortality in 25.8% of patients. Younger age (P = 0.006), lower baseline NIHSS score (P = 0.001), successful recanalization (P < 0.0001), collateral support (P = 0.0008), distal occlusion (P = 0.001), and shorter procedure duration (P = 0.01) were associated with a favorable outcome. Factors affecting successful recanalization included younger age (P = 0.01), lower baseline NIHSS score (P = 0.05), collateral support (P = 0.01), and shorter procedure duration (P = 0.03). An ICA terminus occlusion (P < 0.0001), lack of collaterals (P = 0.0003), and unsuccessful recanalization (P = 0.005) were significantly associated with mortality. Conclusion: Angiographic findings and preprocedure variables can help

    The objective of the MAS evidence review was to conduct a systematic review of the available evidence on the safety, effectiveness, durability and cost-effectiveness of endovascular laser therapy (ELT) for the treatment of primary symptomatic varicose veins (VV). The Ontario Health Technology Advisory Committee (OHTAC) met on November 27, 2009 to review the safety, effectiveness, durability and cost-effectiveness of ELT for the treatment of primary VV based on an evidence-based review by the Medical Advisory Secretariat (MAS). CLINICAL CONDITION: VV are tortuous, twisted, or elongated veins. This can be due to existing (inherited) valve dysfunction or decreased vein elasticity (primary venous reflux) or valve damage from prior thrombotic events (secondary venous reflux). The end result is pooling of blood in the veins, increased venous pressure and subsequent vein enlargement. As a result of high venous pressure, branch vessels balloon out leading to varicosities (varicose veins). SYMPTOMS TYPICALLY AFFECT THE LOWER EXTREMITIES AND INCLUDE (BUT ARE NOT LIMITED TO): aching, swelling, throbbing, night cramps, restless legs, leg fatigue, itching and burning. Left untreated, venous reflux tends to be progressive, often leading to chronic venous insufficiency (CVI). A NUMBER OF COMPLICATIONS ARE ASSOCIATED WITH UNTREATED VENOUS REFLUX: including superficial thrombophlebitis as well as variceal rupture and haemorrhage. CVI often results in chronic skin changes referred to as stasis dermatitis. Stasis dermatitis is comprised of a spectrum of cutaneous abnormalities including edema, hyperpigmentation, eczema, lipodermatosclerosis and stasis ulceration. Ulceration represents the disease end point for severe CVI. CVI is associated with a reduced quality of life particularly in relation to pain, physical function and mobility. In severe cases, VV with ulcers, QOL has been rated to be as bad or worse as other chronic diseases such as back pain and arthritis. Lower limb VV is a

    Aorto-esophageal fistula (AEF) is a rare and lethal entity, and the difficulty of making diagnosis of AEF is well-known. As promising results in the short-term effectiveness of thoracic endovascular aortic repair (TEVAR) promote its usage, the occurrence of AEF after TEVAR (post-TEVAR AEF) increases as one of the major complications. Therefore, we provide a review concerning the management strategy of post-TEVAR AEF. Although its representative symptom was reported as the triad of mid-thoracic pain and sentinel hematemesis followed by massive hematemesis, the symptom-free interval between sentinel hemorrhage and massive exsanguination is unpredictable. However, the physiological condition represents a surgical contraindication. Accordingly, early diagnosis is important, but either CT or esophago-gastro-duodenoscopy rarely depicts a typical image. The formation of post-TEVAR AEF might be associated with the infection of micro-organisms, which is uncontrollable with anti-biotic administration. The current first-line strategy is combination therapy as follows, (1) to control bleeding by TEVAR in the urgent phase, and (2) radical debridement and aortic/esophageal re-construction in the semi-urgent phase. In view of the high mortality and morbidity rate, it is proposed that the choice in treatment strategies might be affected by patient`s condition, size of the wall defects and the etiology of AEF. Practically, we should keep in mind the importance of making an early diagnosis and, once a suspicious symptom has occurred in a patient with a history of TEVAR, the existence of post-TEVAR AEF should be suspected. A prospective registry together with more developed technologies will be needed to establish a future strategy.

    Carotid blowout syndrome is a rare but devastating complication in patients with head and neck malignancy, and is associated with high morbidity and mortality. Bleeding from the carotid artery or its branches is a well-recognized complication following treatment or recurrence of head and neck cancer. It is an emergency situation, and the classical approach to save the patient's life is to ligate the carotid artery. But the surgical treatment is often technically difficult. Endovascular therapies were recently reported as good alternatives to surgical ligation. Retrospective review of three cases of acute or threatened carotid hemorrhage managed by endovascular therapies. Two patients presented with acute carotid blowout, and one patient with a sentinel bleed. Two patients had previously been treated with surgery and chemo radiation. One patient was treated by chemo radiation. Two had developed pharyngocutaneous fistulas, and one had an open necrosis filled wound that surrounded the carotid artery. In two patients, stent placement resolved the acute hemorrhage. In one patient, superselective embolization was done. Mean duration follow-up was 10.2 months. No patient had residual sequelae of stenting or embolization. Management of carotid blow syndrome is very critical and difficult. A multidisciplinary approach is very important in the management of carotid blow syndrome. Correct and suitable management can be life saving. An endovascular technique is a good and effective alternative with much lower morbidity rates than surgical repair or ligation. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Endovascular optical coherence tomography (OCT) is a new imaging modality providing histology-like information of the venous wall. Radiofrequency ablation (RFA) and laser therapy (ELT) are accepted alternatives to surgery. This study evaluated OCT for qualitative assessment of venous wall anatomy and tissue alterations after RFA and ELT in bovine venous specimens. One hundred and thirty-four venous segments were obtained from ten ex-vivo bovine hind limbs. OCT signal characteristics for different wall layers were assessed in 180/216 (83%) quadrants from 54 normal venous cross-sections. Kappa statistics ({kappa}) were used to calculate intra- and inter-observer agreement. Qualitative changes after RFA (VNUS-Closure) and ELT (diode laser 980 nm, energy densities 15 Joules (J)/cm, 25 J/cm, 35 J/cm) were described in 80 venous cross-sections. Normal veins were characterized by a three-layered appearance. After RFA, loss of three-layered appearance and wall thickening at OCT corresponded with circular destruction of tissue structures at histology. Wall defects after ELT ranged from non-transmural punctiform damage to complete perforation, depending on the energy density applied. Intra- and inter-observer agreement for reading OCT images was very high (0.90 and 0.88, respectively). OCT allows for reproducible evaluation of normal venous wall and alterations after endovenous therapy. OCT could prove to be valuable for optimizing endovenous therapy in vivo. (orig.)

    Endovascular reperfusion therapy is increasingly used for acute ischemic stroke treatment. The occurrence of parenchymal hemorrhage is clinically relevant and increases with reperfusion therapies. Herein we aimed to examine the optimal perfusion CT-derived parameters and the impact of the duration of brain ischemia for the prediction of parenchymal hemorrhage after endovascular therapy. A cohort of 146 consecutive patients with anterior circulation occlusions and treated with endovascular reperfusion therapy was analyzed. Recanalization was assessed at the end of reperfusion treatment, and the rate of parenchymal hemorrhage at follow-up neuroimaging. In regression analyses, cerebral blood volume and cerebral blood flow performed better than Delay Time maps for the prediction of parenchymal hemorrhage. The most informative thresholds (receiver operating curves) for relative cerebral blood volume and relative cerebral blood flow were values lower than 2.5% of normal brain. In binary regression analyses, the volume of regions with reduced relative cerebral blood volume and/or relative cerebral blood flow was significantly associated with an increased risk of parenchymal hemorrhage, as well as delayed vessel recanalization. These results highlight the relevance of the severity and duration of ischemia as drivers of blood-brain barrier disruption in acute ischemic stroke and support the role of perfusion CT for the prediction of parenchymal hemorrhage.

    Uncertainty persists regarding the safety and efficacy of endovascular therapy of M2 occlusions following IV tPA. We reviewed the impact of revascularization on clinical outcomes in 83 patients with M2 occlusions in the Interventional Management of Stroke III trial according to specific M1-M2 segment anatomic features. Perfusion of any M2 branch distinguished M2-versus-M1 occlusion. Prespecified modified TICI and arterial occlusive lesion revascularization and clinical mRS 0-2 end points at 90 days for endovascular therapy-treated M2 occlusions were analyzed. Post hoc analyses of the relationship of outcomes to multiple baseline angiographic M2 and M1 subgroup characteristics were performed. Of 83 participants with M2 occlusion who underwent endovascular therapy, 41.0% achieved mRS 0-2 at 90 days, including 46.6% with modified TICI 2-3 reperfusion compared with 26.1% with modified TICI 0-1 reperfusion (risk difference, 20.6%; 95% CI, -1.4%-42.5%). mRS 0-2 outcome was associated with reperfusion for M2 trunk (n = 9) or M2 division (n = 42) occlusions, but not for M2 branch occlusions (n = 28). Of participants with trunk and division occlusions, 63.2% with modified TICI 2a and 42.9% with modified TICI 2b reperfusion achieved mRS 0-2 outcomes; mRS 0-2 outcomes for M2 trunk occlusions (33%) did not differ from distal (38.2%) and proximal (26.9%) M1 occlusions. mRS 0-2 at 90 days was dependent on reperfusion for M2 trunk but not for M2 branch occlusions. For M2 division occlusions, good outcome with modified TICI 2b reperfusion did not differ from that in modified TICI 2a. M2 segment definition and occlusion location may contribute to differences in revascularization and good outcome between Interventional Management of Stroke III and other endovascular therapy studies. © 2017 by American Journal of Neuroradiology.

    Objectives: Endovascular treatment is effective in treating carotid blowout syndrome (CBS). We reviewed our experience in addressing CBS over eight years and presented an account of the treatment paradigm and management algorithm. Method: All cases of CBS from 2003 to 2010 with endovascular treatment performed in our center were reviewed. 15 CBS in 14 patients were recruited. Based on our management algorithm, treatment regimen was stratified into deconstructive or constructive methods. Their clinical presentations, angiographic features, angiographic and clinical outcomes were reviewed. Results: 10 patients were treated with deconstructive method by means of permanent vessel occlusion (PVO) and 4 patients were treated with constructive method by means of placement of covered stent (n = 3) or flow diverting device (n = 1). Immediate hemostasis was achieved in all cases. 7 (50%) patients, in whom 5 treated with PVO and 2 with covered stent, had favorable outcomes and survived at a median follow-up period of 4 months (range: 1–84 months). Conclusion: Permanent vessel occlusion remains the gold standard of treatment and tends to show a favorable long-term outcome. Off-label use of covered stent and flow-diverting device can produce satisfactory results should balloon occlusion test fail, but long-term follow up would be required for definitive assessment.

    Objectives: Endovascular treatment is effective in treating carotid blowout syndrome (CBS). We reviewed our experience in addressing CBS over eight years and presented an account of the treatment paradigm and management algorithm. Method: All cases of CBS from 2003 to 2010 with endovascular treatment performed in our center were reviewed. 15 CBS in 14 patients were recruited. Based on our management algorithm, treatment regimen was stratified into deconstructive or constructive methods. Their clinical presentations, angiographic features, angiographic and clinical outcomes were reviewed. Results: 10 patients were treated with deconstructive method by means of permanent vessel occlusion (PVO) and 4 patients were treated with constructive method by means of placement of covered stent (n = 3) or flow diverting device (n = 1). Immediate hemostasis was achieved in all cases. 7 (50%) patients, in whom 5 treated with PVO and 2 with covered stent, had favorable outcomes and survived at a median follow-up period of 4 months (range: 1–84 months). Conclusion: Permanent vessel occlusion remains the gold standard of treatment and tends to show a favorable long-term outcome.

    To evaluate the efficacy and safety of endovascular treatment, particularly adjunctive intra-arterial mechanical thrombectomy, in patients with ischaemic stroke. Systematic review and meta-analysis. Medline, Embase, Cochrane Central Register of Controlled Trials, Web of Science, SciELO, LILACS, and clinical trial registries from inception to December 2015. Reference lists were crosschecked. Randomised controlled trials in adults aged 18 or more with ischaemic stroke comparing endovascular treatment, including thrombectomy, with medical care alone, including intravenous recombinant tissue plasminogen activator (rt-PA). Trial endpoints were functional outcome (modified Rankin scale scores of ≤2) and mortality at 90 days after onset of symptoms. No language or time restrictions applied. 10 randomised controlled trials (n=2925) were included. In pooled analysis endovascular treatment, including thrombectomy, was associated with a higher proportion of patients experiencing good (modified Rankin scale scores ≤2) and excellent (scores ≤1) outcomes 90 days after stroke, without differences in mortality or rates for symptomatic intracranial haemorrhage, compared with patients randomised to medical care alone, including intravenous rt-PA. Heterogeneity was high among studies. The more recent studies (seven randomised controlled trials, published or presented in 2015) proved better suited to evaluate the effect of adjunctive intra-arterial mechanical thrombectomy on its index disease owing to more accurate patient selection, intravenous rt-PA being administered at a higher rate and earlier, and the use of more efficient thrombectomy devices. In most of these studies, more than 86% of the patients were treated with stent retrievers, and rates of recanalisation were higher (>58%) than previously reported. Subgroup analysis of these seven studies yielded a risk ratio of 1.56 (95% confidence interval 1.38 to 1.75) for good functional outcomes and 0.86 (0.69 to 1.06) for

    Open surgery is a frequent option given to patients with unruptured intracranial aneurysms (UIAs) unsuitable for endovascular repair. Since the risk of rupture of UIAs is generally low, we determined whether the risks and costs of surgery in this patient subset are warranted. The safety, efficacy, and costs of minimally invasive surgery by minicraniotomy were evaluated in 102 consecutive patients with anterior circulation UIAs deemed unsuitable for endovascular repair by an interdisciplinary conference of surgeons and neurointerventionalists. Data from 107 UIA patients treated by endovascular means in the same period were used as the standard. Surgical patients comprised a different subset of aneurysms, with more MCA and fewer paraophthalmic aneurysms (54 vs. 6, p < 0.0001 and 4 vs. 60, p < 0.0001, for minicraniotomy and endovascular, respectively). However, surgery incurred shorter anesthesia time (197.7 vs. 149.3 min, p < 0.0001), higher rates of complete aneurysm obliteration (94.57 vs. 66.67 %, p < 0.0001), and lower overall hospital costs ($8,287 CAD vs. $17,732 CAD, p < 0.0001) than the endovascular cohort. There were no treatment-related surgical deaths, but one patient had an mRS of 3 after 6 months due to temporal lobe epilepsy and memory problems. This compared favorably with the endovascular cohort in which two patients died due to treatment (mRS = 6) and one suffered a severe stroke (mRS = 5 at 6 months). For patients counseled to undergo treatment but have UIAs unsuitable for endovascular repair, surgery is safe, effective, and cost-efficient.

    Evidence-based and guideline-conforming treatment of claudication in Fontaine stage IIb due to peripheral artery disease is basically conservative. However, many patients in Fontaine stage IIb disease are treated also treated surgically, e.g. with bypass operations or endarterectomy, or with endovascular methods (angioplasty and variations thereof ). The present study compares patient satisfaction with these three therapy modalities. Methods: 666 patients with Fontaine IIb cla...

    To determine the predictive value of skin perfusion pressure (SPP) for wound healing after endovascular therapy (EVT). Between May 2004 and March 2011, 113 consecutive patients (84 men; mean age 71.5±12.5 years) with CLI (123 limbs) underwent successful balloon angioplasty ± stenting (flow from >1 vessel to the foot without bypass) and were physically able to undergo SPP measurement before and within 48 hours after EVT. The status of wound healing was recorded over a mean follow-up of 17.4±12.4 months. The wound healing rate was 78.9% (97 limbs of 89 patients). SPP values after EVT were significantly higher in these patients than in the 24 patients (26 limbs) without wound healing (44.2±15.6 mmHg vs. 27.5±10.4 mmHg, pwound healing had an area under the curve of 0.81 (95% CI 0.723 to 0.899, pwound healing was 30 mmHg, with a sensitivity of 81.4% and a specificity of 69.2%. Binary logistic regression analysis demonstrated SPP after EVT to be an independent predictor of wound healing (pwound healing with SPP values >30 mmHg, 40 mmHg, and 50 mmHg were 69.8%, 86.3%, and 94.5%, respectively. SPP after EVT is an independent predictor of wound healing in patients with CLI. In our study, an SPP value of 30 mmHg was shown to be the best cutoff for prediction of wound healing after EVT.

    Atrial fibrillation (AF) is the most common cardiac arrhythmia. The mortality rate of patients with AF is doubled as compared to non-fibrillating controls. The most relevant complication of AF is a major increase in the risk of stroke. The gold standard in reducing cerebrovascular events in AF is warfarin therapy, which is not free from contraindications and limitations. The left atrial appendage (LAA) is the main source of emboli causing stroke in AF. LAA closure is a seducing approach to stroke risk reduction in AF without anticoagulation. Since 1949, heart surgeons have performed LAA closure or amputation in patients with AF. Percutaneous endovascular LAA closure is a new, less invasive, technique to reach the goal. Several devices have been used to perform this intervention, and the results of published trials are encouraging in terms of effectiveness and relative safety of this attractive technique. In this review we examine the published trials and data on percutaneous LAA closure, with particular attention to the risks and benefits of this procedure.

    The purpose of this review is to compare conventional endovascular procedures and the robotic endovascular approach in aortic aneurysm repair. Despite advantages over open surgery, conventional endovascular surgery has limitations. To develop an alternative, efforts have been focused on robotic endovascular systems. Two of the 3 studies comparing procedure times demonstrated reduced procedure time in the robotic group, by 6 times (p robotic procedures reduced fluoroscopic exposure time by 12 minute (p robotic surgery was reduced up to 10 times (p robotic performance score showed a better performance score in the robotic endovascular group (p = 0.007). These results demonstrate that the robotic technique has multiple advantages over the conventional procedure, including improved catheter stability, a shorter learning curve, reduced procedure time, and better performance in cannulating tortuous vessels. However, robotic endovascular technology may be limited by the cost of the system, the size of the catheter, and the setup time required preoperatively. Further comparative studies between conventional and robotic approaches regarding cost-effectiveness, safety, and performance in cases involving complex anatomy and fenestrated stent grafts are essential. Nevertheless, this revolutionary technology is increasingly popular and may be the next milestone in endovascular surgery.

As DSA became widely available and the potential benefits for accessing the cerebral vasculature from an endovascular approach began to be apparent, industry began efforts to develop tools for use in these procedures. Along with development of catheters, embolic materials, pushable coils and the GDC coils there was simultaneous development and improvement of 2D DSA image quality and the introduction of 3D DSA.

    Method: In 22 patients (15 men, 7 women, a tumour-related compression of the superior vena cava was diagnosed by spiral CT after intravenous application of contrast medium. Clinically, acute superior vena cava syndrome was found in all patients. Histologically, a bronchial carcinoma was present in 14/22, a lymphoma in 6/22, and mediastinal lymphnode metastases (1 breast carcinoma, 1 malignant melanoma in 2/22. After a transfemoral approach, cavography was initially performed. The degree of stenosis was classified according to the Stanford classification. In accordance with the degree of stenosis, a self-expanding Nitinol stent was placed. Results: Endovascular stent implantation was conducted without complications in all patients. A marked improvement in acute symptoms was observed clinically within 24 hours in all patients. In the follow-up period of up to 2 years, there were no cases of stent migration. In 7/22 patients, the CT follow-ups revealed tumour progression (3/7 after 3 months, 2/7 after 6 months, and 2/7 after 12 months with evidence of residual stenosis caused by tumour growth through the stent mesh. During the follow-up period, 15/22 patients died (mean survival 6.4 months. Conclusion: Self-expanding Nitinol stents provide endovascular therapy for superior vena cava syndrome, having a high radial expansive force and the facility to be placed precisely, and alleviating acute, life-threatening symptoms in the palliative situation.

    Full Text Available Abstract: Symptomatic intracranial atherosclerotic disease (ICAD is responsible for approximately 10% of all ischemic strokes in the United States. The risk of recurrent stroke may be as high as 35% in patient with critical stenosis greater than 70% in diameter narrowing. Recent advances in medical and endovascular therapy have placed ICAD at the forefront of clinical stroke research to optimize the best medical and endovascular approach to treat this important underlying stroke etiology. Analysis of symptomatic ICAD studies lead to the question that whether angioplasty and or stenting is a safe, suitable and efficacious therapeutic strategy in patients with critical stenoses that are deemed refractory to medical management. Most of the currently available data in support of angioplasty and or stenting in high risk patients with severe symptomatic ICAD is in the form of case series and randomized trial results of endovascular therapy versus medical treatment are awaited. This is a comprehensive review of the state of the art in the endovascular approach with angioplasty and or stenting of symptomatic intracranial atherosclerotic disease.

    To evaluate the results of interventional endovascular therapy of incidental and symptomatic visceral artery aneurysms in the elective and emergency situation. 43 aneurysms in 38 patients (19 female, 19 male, mean age: 57 ± 16 years [18-82]) were treated between 2011 and 2015. The characteristics of the aneurysms (true vs. false aneurysm, size, etiology, location, symptoms) were considered. Furthermore, we evaluated the intervention with respect to technical success, embolic/occlusive agents used, therapy-associated complications and post-interventional follow-up. 23 true aneurysms (maximum diameter: 22 ± 18 mm [11 - 67mm]) and 20 false aneurysms (maximum diameter: 9 ± 33 mm [3 - 150 mm]) were evaluated. The splenic (n = 14) and renal arteries (n = 18) were most frequently affected. The etiology was most commonly degenerative-atherosclerotic (47%) or iatrogenic post-operative (19%). 18/48 interventions were performed due to active bleeding. False aneurysms were associated significantly more often with active bleeding (63 vs. 25%, p = 0.012). 41/48 treatments were technically successful. Re-intervention was necessary 6 times. In 2 cases the endovascular approach did not succeed. There was a complication rate of 10%, whereby only 4 minor and 1 major complications occurred. No patient suffered from permanent sequelae. Aneurysms were primarily treated by using coils and if necessary additional embolic agents (liquid embolic agent or vascular plugs) (75%). In the follow-up period, reperfusion of treated aneurysms occurred at a rate of 7% (n = 3). Interventional endovascular therapy of visceral artery aneurysms is safe and effective in the elective treatment of incidental aneurysms as well as in significantly more frequent hemorrhaging false aneurysms in the emergency situation.

    Background and Purpose We assessed the effect of endovascular treatment in acute ischemic stroke patients with severe neurological deficit (NIHSS ≥20) following a pre-specified analysis plan. Methods The pooled analysis of the IMS III and MR CLEAN trial included participants with an NIHSS ≥20 prior to intravenous (IV) t-PA treatment (IMS III) or randomization (MR CLEAN) who were treated with IV t-PA ≤ 3 hours of stroke onset. Our hypothesis was that participants with severe stroke randomized to endovascular therapy following IV t-PA would have improved 90-day outcome (distribution of modified Rankin scale [mRS] scores), as compared to those who received IV t-PA alone. Results Among 342 participants in the pooled analysis (194 from IMS III, 148 from MR CLEAN), an ordinal logistic regression model showed that the endovascular group had superior 90-day outcome compared to the IV t-PA group (adjusted odds ratio [aOR] 1.78; 95% confidence interval [CI] 1.20-2.66). In the logistic regression model of the dichotomous outcome (mRS 0-2, or ‘functional independence’), the endovascular group had superior outcomes (aOR 1.97; 95% CI 1.09-3.56). Functional independence (mRS ≤2) at 90 days was 25% in the endovascular group as compared to 14% in the IV t-PA group. Conclusions Endovascular therapy following IV t-PA within 3 hours of symptom onset improves functional outcome at 90 days after severe ischemic stroke. PMID:26486865

    In this review, massage therapy has been shown to have beneficial effects on varying conditions including prenatal depression, preterm infants, full-term infants, autism, skin conditions, pain syndromes including arthritis and fibromyalgia, hypertension, autoimmune conditions including asthma and multiple sclerosis, immune conditions including HIV and breast cancer and aging problems including Parkinson's and dementia. Although many of the studies have involved comparisons between massage therapy and standard treatment control groups, several have compared different forms of massage (e.g. Swedish versus Thai massage), and different active therapies such as massage versus exercise. Typically, the massage therapy groups have experienced more positive effects than the control or comparison groups. This may relate to the massage therapy providing more stimulation of pressure receptors, in turn enhancing vagal activity and reducing cortisol levels. Some of the researchers have assessed physical, physiological and biochemical effects, although most have relied exclusively on self-report measures. Despite these methodological problems and the dearth of research from the U.S., the massage therapy profession has grown significantly and massage therapy is increasingly practiced in traditional medical settings, highlighting the need for more rigorous research.

    To systematically review and meta-analyze the added value of 3-dimensional (3D) image fusion technology in endovascular aortic repair for its potential to reduce contrast media volume, radiation dose, procedure time, and fluoroscopy time. Electronic databases were systematically searched for studies published between January 2010 and March 2016 that included a control group describing 3D fusion imaging in endovascular aortic procedures. Two independent reviewers assessed the methodological quality of the included studies and extracted data on iodinated contrast volume, radiation dose, procedure time, and fluoroscopy time. The contrast use for standard and complex endovascular aortic repairs (fenestrated, branched, and chimney) were pooled using a random-effects model; outcomes are reported as the mean difference with 95% confidence intervals (CIs). Seven studies, 5 retrospective and 2 prospective, involving 921 patients were selected for analysis. The methodological quality of the studies was moderate (median 17, range 15-18). The use of fusion imaging led to an estimated mean reduction in iodinated contrast of 40.1 mL (95% CI 16.4 to 63.7, p=0.002) for standard procedures and a mean 70.7 mL (95% CI 44.8 to 96.6, p<0.001) for complex repairs. Secondary outcome measures were not pooled because of potential bias in nonrandomized data, but radiation doses, procedure times, and fluoroscopy times were lower, although not always significantly, in the fusion group in 6 of the 7 studies. Compared with the control group, 3D fusion imaging is associated with a significant reduction in the volume of contrast employed for standard and complex endovascular aortic procedures, which can be particularly important in patients with renal failure. Radiation doses, procedure times, and fluoroscopy times were reduced when 3D fusion was used.

    Full Text Available Introduction. The best treatment for unruptured middle cerebral artery (MCA aneurysms is unclear. We perform a meta-analysis of recent publications to evaluate the results of unruptured MCA aneurysms treated with surgical clipping and endovascular coiling. Methods. A PubMed search for articles published between January 2004 and November 2013 was performed. The R statistical software package was used to create a random effects model for each desired incidence rate. Cochran’s Q test was used to evaluate possible heterogeneity among the rates observed in each study. Results. A total of 1891 unruptured MCA aneurysms, 1052 clipped and 839 coiled, were included for analysis. The complete occlusion rate at 6–9 months mean follow-up was 95.5% in the clipped group and 67.8% in the coiled group (P<0.05. The periprocedural thromboembolism rate in the clipping group was 1.8% compared with 10.7% in the aneurysms treated by coiling (P<0.05. The recanalization rate was 0% for clipping and 14.3% for coiling (P=0.05. Modified Rankin scores of 0–2 were obtained in 98.9% of clipped patients compared to 95.5% of coiled (NS. Conclusions. This review weakly supports clipping as the preferred treatment of unruptured MCA aneurysms. Clinical outcomes did not differ significantly between the two groups.

    To analyze early technical success and late clinical success after endovascular entry sealing for chronic type B dissection with special emphasis on reintervention, false lumen thrombosis, and aortic remodeling. Retrospective analysis of a prospective database. From September 1999 to January 2011, 19 patients with chronic type B dissections were treated by endovascular entry sealing. Median age was 60 years. Median time between onset of acute dissection and surgical intervention was 36 (1 to 60) months. Median follow-up was 13 months (1 to 124). The endografts used were: Medtronic Captivia (5), Medtronic Valiant (5), Gore TAG (6), Gore C-TAG (2), and Cook Zenith (1). In four patients, revascularization of the left subclavian artery was performed prior to entry sealing. Primary technical success rate (entry sealing, absence of type I leak) was 18/19 (94.7%). In-hospital mortality was 0%. Spinal cord injury with persistent paraplegia occurred in 1/19 (5.2%) patients. After a maximal follow-up of 124 months, reinterventions in 9/19 (47.3%) were necessary: distal/proximal extension of stent graft (8), replacement of the aortic arch due to retrograde dissection (1), and open infrarenal aneurysm repair (1). During follow-up, none of the patients died due to stent-related complications. Endovascular treatment (EVT) in chronic type B dissections has a high technical success rate and low mortality/morbidity. However reintervention rates are not negligible which might reduce the clinical success of EVT. Future investigations should aim at identifying patients who benefit from EVT at better defining the timing of EVT and at determining if entry sealing alone is sufficient.

    Critical limb ischemia (CLI) patients with tissue loss have been recognized to have a poor survival rate. In this study, we aimed to determine whether the prognosis of CLI patients with tissue loss improves after complete wound healing is achieved by endovascular therapy. We treated 187 CLI patients with tissue loss by endovascular therapy from April 2007 to December 2012. Among these patients, 113 patients who achieved complete wound healing were enrolled. The primary end point was survival rate at 3 years. The secondary end points were limb salvage rate and recurrence rate of CLI at 3 years. The mean follow-up period after achievement of complete wound healing was 32 ± 18 months. At 1 year, 2 years, and 3 years, the survival rates were 86%, 79%, and 74%; the limb salvage rates were 100%, 100%, and 100%; the recurrence rates of CLI were 2%, 6%, and 9%, respectively. On multivariate Cox proportional hazard analysis, age >75 years (hazard ratio, 3.18; 95% confidence interval, 1.23-8.24; P = .017) and nonambulatory status (hazard ratio, 2.46; 95% confidence interval, 1.08-5.65; P = .035) were identified as independent predictors of death for CLI patients with tissue loss even after complete wound healing was achieved. The Kaplan-Meier curve for the overall survival rate at 3 years showed that CLI patients of older age (>75 years) had a significantly decreased survival rate compared with CLI patients of younger age (≤75 years) (58% vs 87%; log-rank test, P wound healing was achieved. Nonambulatory status and age >75 years can serve as predictors of death even after complete wound healing is achieved. Copyright © 2015 Society for Vascular Surgery. Published by Elsevier Inc.

    Full Text Available Over the last decades, improvement of medical and surgical therapy has increased life expectancy in Marfan patients. Consequently, the number of such patients requiring secondary interventions on the descending thoracic aorta due to new or residual dissections, and distal aneurysm formation has substantially enlarged. Surgical and endovascular procedures represent two valuable options of treatment, both associated with advantages and drawbacks. The aim of the present manuscript was to review endovascular outcomes in Marfan syndrome and to assess the potential role of Thoracic Endovascular Aortic Repair (TEVAR in this subset of patients.

    Analytic review of domestic and foreign literature dedicated to X-ray endovascular studies in the therapy for malignant tumors aiming to diagnose and treat tumors showed a great interest to the agent named Lipiodol Ultra Fluid, developed by Guerbet (France) that is oil soluble radio-opaque agent meant mainly for lymphography and sialography. The interest of researchers is caused by the ability of Lipiodol to penetrate into tumor cells and stay there for a long time expressing diagnostic efficacy and in a number of cases expressing anti-tumor effect. The authors note that the mechanism of anti-tumor effect of Lipiodol is still unclear. High viscosity of Lipiodol can be considered as its shortages that at giving intravascular therapy with Lipiodol it can result in embolism of organs of vital importance. The present study was aimed to develop effective oil soluble radio-opaque agent that would not cause vessels embolism but could infiltrate neoplastic tissue while administrating it into vessels of the tumors of parenchymastous organs.

    Full Text Available Abstract Background To compare the effects of endovascular coiling and neurosurgical clipping in patients with unruptured intracranial aneurysm. Methods Sixteen electronic databases were searched for articles published between 1950 and July 2010 to compare clinical outcomes of clipping and coiling. Researchers reviewed all searched articles and extracted data independently. The quality of studies and evidence were evaluated using MINORS and GRADEprofiler, respectively. The odds ratio (OR was calculated using the inverse variance meta-analysis method for each study outcome. To assess heterogeneity of ORs across cohorts, Cochran’s Q statistic and I2 were used. Results Of 4160 studies, 24 were identified (n  =  31865. Clipping resulted in significantly higher disability using the Glasgow Outcome Scale (OR, 2.38; 95% CI, 1.33–4.26 and Modified Rankin Scale (OR, 2.83; 95% CI, 1.42–5.63 when compared with coiling. ORs for complications were also higher with clipping (ORs for neurological and cardiac complications were 1.94 with a 95% confidence interval [CI] of 1.09–3.47 and 2.51 with a 95% CI of 1.15–5.50. Clipping resulted in significantly greater disability in the short term (≤6 m(OR on the Glasgow Outcome Scale, 2.72; 95% CI, 1.16–6.34, but not in the long term (>6 m(OR for Glasgow Outcome Scale, 2.12; 95% CI, 0.93–4.84. Conclusions Coiling was a better procedure for treatment of unruptured intracranial aneurysm in terms of disability, complications, especially in the short term. Because of the limitations of the reviewed studies, further studies are required to support the present results.

    Head and neck arteriovenous malformations (H and N AVM) are associated with considerable clinical and psychosocial burden and present a significant treatment challenge. We evaluated the presentation, response to treatment, and outcome of patients with H and N AVMs treated by endovascular means at our institution. Patients with H and N AVMs treated by endovascular means from 1984 to 2012 were evaluated retrospectively. These included AVMs involving the scalp, orbit, maxillofacial, and upper neck localizations. Patient's clinical files, radiological images, catheter angiograms, and surgical reports were reviewed. Eighty-nine patients with H and N AVMs (46 females, 43 males; 48 small, 41 large) received endovascular therapy. The goals of treatment were curative (n = 30), palliative (n = 34), or presurgical (n = 25). The total number of endovascular treatment sessions was 244 (average of 1.5 per patient). The goal of treatment was met in 92.1 % of cases. Eventual cure was achieved in 42 patients accounting for 58.4 % (52/89) of all patients who underwent treatment for any goal. Twenty-eight of these patients were cured by embolization alone (28/89, 31.4 %) of which 18 were single-hole AVFs. Twenty-four were cured by planned surgical excision after presurgical embolization (24/89, 27 %). Seven patients (7/89, 7.2 %) suffered transient and two (2/89, 2.2 %) permanent endovascular treatment complications. Endovascular treatment is effective for H and N AVMs and relatively safe. It is particularly effective for symptom palliation and presurgical aid. Embolization is curative mostly in small lesions and single-hole fistulas. In patients with large non-curable H and N AVMs, endovascular therapy is often the only palliative option. (orig.)

    Objective: To evaluate the safety and efficacy of multimodal reperfusion therapy (MMRT) for acute tandem internal carotid artery and middle cerebral artery (TIM)occlusions. Methods: Six cases of TIM occlusions were analyzed retrospectively, including etiology,sites of tandem occlusion, compensation, location and size of infarcts, mechanical recanalization technique and its complications. Changes of National Institute of Health Stroke Scale (NIHSS) score and image findings between pre-and post-procedure were further compared. The modified Rankin scores (mRS) were used to assess clinical prognosis. Results: The NIHSS score on admission was 13-20, and the time of procedure ranged 60-230 min. Five cases was substantial recanalized and no symptomatic intracerebral hemorrhage was observed. The NIHSS scores of the patients on day 3 after surgery were 7-19, and those were 3-17 when being discharged. One patient died of pulmonary infection 1 month after discharge. For the 5 patients who survived, the modified Rankin Scale (mRS) was evaluated at 3 months with scores of 0, 2, 3, 3 and 5, respectively. Conclusions: Endovascular therapy for acute TIM occlusions are complex, MMRT may be relatively safe and effective. (authors)

    Prospective study to evaluate clinical results and complications of endovascular abdominal aortic aneurysm treatment in a mid-term follow-up. Materials and methods: A total of 122 patients (9 females, 113 males, average age 70.0±7,9 years) with abdominal aortic aneurysms were treated with stent grafts (53 Vanguard or Stentor endografts, 69 Talent endografts). Group I consisted of 40 patients who had all aortic tributaries of the aneurysm sac occluded prior to endovalscular grafting, either spontaneously by parietal thrombosis or by selective coil embolization of the respective ostia preserving collateral circulation distal to the vessel occlusion. Group II consisted of 82 patients and included all cases without or with incomplete coil embolization with at least one patent vessel. Stent grafting was performed in general anesthesia in the first 21 patients, followed by peridural anesthesia in 15 cases, and local anesthesia with conscious sedation in 86 cases. The results were evaluated with Spiral-CT, MRI and radiographs of the endovascular graft, with follow-up examinations obtained at 3, 6, 12 months, and every year - Implantation was successfully completed in all cases without primary conversion surgery, laparotomy or any significant complication. Mean follow-up was 29±21 months (maximum 82 months). The 30-day mortality was 0,8% due to a myocardial infarction 3 days after discharge from the hospital. A total of 47 re-interventions were performed in 29 patients (23.8%), with 35 re-interventions in 18 cases with Vanguard or Stentor endografts and 12 re-interventions in 11 patients with Talent endografts. 23 percutaneous re-interventions included distal graft extension (n=11), Wallstent for kinking and limb stenosis (n=3), and secondary coil embolization of collateral vessels (n=9). 24 surgical re-interventions included proximal graft extension (n=6), new endovascular grafts (n=3), surgical clipping of lumbar and mesenteric artery branches for type-II endoleaks

    Legitimacy of entry-oriented therapy for DeBakey I aortic dissection is of eminent importance in the era of emerging ascending aorta endovascular therapy. This study aims to evaluate early, midterm, and reintervention results of entry-oriented operative strategy compared to more aggressive strategies for treatment of DeBakey type I aortic dissection with an isolated intimal tear in the ascending aorta. This study prospectively followed 98 consecutive patients who received an operation for DeBakey type I aortic dissection with the intimal tear in the ascending aorta between 2007 and 2013 for up to 6 years. Follow-up included survival, medical therapy, CT-imaging results, and reinterventions. Patients were grouped into entry-oriented (group I) receiving an isolated replacement of the ascending aorta and/or hemiarch (65 patients); and aggressive therapy (group II) receiving a replacement of the ascending aorta and complete aortic arch (33 patients). Results: The in-hospital mortality was 19% and 23% respectively. The 3-year survival was 52% and 47% respectively (P = .193). Group II showed no advantage regarding persistence or progression of the dissection, thrombosis of false lumen, increase in aortic diameter, peripheral organ malperfusion (as assessed by follow-up computed tomography imaging) or freedom from reintervention. Conclusion: In treating DeBakey I aortic dissection with an entry tear in the ascending aorta, it might be legitimate to adopt an entry-oriented operative strategy. Further research is also needed to clearly describe the indication of extending the operative strategy in such cases.

    Healthcare expenditures and cost reduction have been under critical surveillance in all countries and are critical for policymakers. This review aims at qualitatively and quantitatively analyzing the difference of hospital costs and length of stay between endovascular coiling versus neurosurgical clipping in ruptured intracranial aneurysms (RAs). MEDLINE, the Cochrane database, Embase, and the Web of Science database were searched and evaluated independently by 2 authors according to the Newcastle-Ottawa Scale for cohort studies describing economic hospital cost or length of stay in patients with RAs. A total of 8 studies were included, describing 24,219 RAs treated with neurosurgical clipping and 24,962 RAs with endovascular coiling. Meta-analysis revealed that the total hospital costs (THCs) were similar between coiling versus clipping in RAs (standard mean difference [SMD], -0.05; 95% confidence interval [CI], -0.12 to 0.22; I 2  = 99%; P = 0.50). Subgroup analysis showed that THCs of clipping and coiling were similar in ruptured aneurysms in the United States. However, in South Korea, the THCs of coiling were significantly higher than clipping. In the long run, 1-year medical costs of endovascular treatment were significantly lower than that of clipping in RAs (SMD, 0.15; 95% CI, 0.05-0.25; I 2  = 66%; P = 0.005). In addition, the length of stay of coiled patients was significantly shorter than clipped patients (SMD, 0.29; 95% CI, 0.13-0.45; I 2  = 96%; P China, coiling was more expensive. The length of stay was much shorter in coiled patients in all countries. Copyright © 2018. Published by Elsevier Inc.

    It is still unclear how often subarachnoid hemorrhage (SAH) leads to chronic hemosiderin depositions. In this study, we aimed to determine the frequency of chronic hemosiderin depositions after aneurysmal SAH in patients who did not undergo surgery. Furthermore, we analyzed typical MRI patterns of chronic SAH and sought to obtain information on the temporal course of MRI signal changes. We retrospectively analyzed 90 patients who had undergone endovascular treatment for acute aneurysmal SAH. In all patients, initial CT studies and at least one T2*-weighted MRI obtained 6 months or later after SAH were analyzed for the presence and anatomical distribution of SAH or chronic hemosiderin depositions. In total, 185 T2*-weighted MRI studies obtained between 2 days and 148 months after SAH were evaluated (mean follow-up 30.2 months). On MRI studies obtained later than 6 months after SAH, subpial hemosiderin depositions were found in 50 patients (55.5 %). Most frequent localizations were the parenchyma adjacent to the frontal and parietal sulci and the insular cisterns. While the appearance of hemosiderin depositions was dynamic within the first 3 months, no changes were found during subsequent follow-up. MR signal changes were not only conclusive with subarachnoid hemosiderin depositions but in many cases also resembled those that have been associated with cortical hemosiderosis. T2*-weighted MRI is an effective means of diagnosing prior SAH. Our study suggests that chronic hemosiderin depositions can be found in a considerable number of patients after a single event of subarachnoid hemorrhage. (orig.)

    To compare the characteristics and outcomes of multimodal endovascular therapy (EVT) in patients with acute basilar artery occlusion (BAO) with and without underlying intracranial atherosclerotic stenosis (ICAS). We retrospectively analyzed the data from 50 patients with acute BAO who were treated with EVT. The baseline characteristics and outcomes of patients with and without ICAS were compared. Patients with ICAS underwent intracranial angioplasty or stenting after mechanical thrombectomy. Thirty percent of the patients (15/50) had underlying ICAS at the occlusion site. On pretreatment diffusion-weighted imaging (DWI), bilateral thalamic infarction was less frequently found in patients with ICAS (0% vs. 25.7%, p = 0.03). Occlusion in the proximal segment of the basilar artery was more common in patients with ICAS (60% vs. 5.7%, p < 0.001), whereas occlusion in the distal segment of the basilar artery was more common in patients without ICAS (26.7% vs. 91.4%, p < 0.001). There were no significant differences in the rates of successful revascularization, 3-month modified Rankin Scale scores of 0–2, symptomatic hemorrhage, and mortality between the two groups. ICAS was common in patients with acute stroke due to BAO. The occlusion site and the presence or absence of bilateral thalamic infarction on pretreatment DWI might help predict the underlying ICAS in patients with acute BAO.

    We clarified characteristics and clinical outcomes of critical limb ischemia (CLI) patients who underwent repeat endovascular therapy (EVT) for infrapopliteal lesions. High restenosis rate after infrapopliteal EVT remains a major concern. Patients with CLI who underwent EVT between April 2007 and February 2014, were divided into the following three groups according to how often EVT was repeated: Group A, no repeat of EVT; Group B, EVT repeated once/twice; and Group C, EVT repeated ≥3 times. Wound healing rates at 1 year were 93.9% in Group A, 77.1% in Group B, and 27.3% in Group C (P WIfI (OR 2.440, 1.417-4.203, P = 0.001) were independent predictors of repeat EVT. The rate of requirement for repeat EVT significantly increased as clinical stage became more severe (repeat EVT rate: 0% in CS 1, 28.6% in CS 2, 34.0% in CS 3, and 45.7% in CS 4, P WIfI clinical stage may be useful to predict the necessity of repeat EVT. © 2017 Wiley Periodicals, Inc.

    Endovascular thrombectomy (ET) is safe, effective, and cost-effective for large artery occlusion ischemic stroke, even if under different selection criteria. To study the preferences for ET selection criteria by surveying clinicians and consumers, where number needed to treat to achieve functional independence is the only factor being considered. A survey providing visual representation of the proportion of patients treated and expected functional outcomes, based on the selection criteria in each of the recent randomized trials of ET, was distributed nationwide in Australia and New Zealand to clinicians and consumers. The preferred selection criteria were identified by the frequency of first choice and using decision-analysis techniques to assess consensus by treating respondents as a panel of experts and aggregating their preferences on selection criteria. 104 clinicians and 107 consumer respondents (43/107 (40%) stroke survivors) took part in the study. Selection criteria of EXTEND-IA were ranked as the most preferred by the consensus process analysis and were the first choice of 64 individual clinicians (61.5%; 95% CI 52% to 71%). ESCAPE trial selection criteria were ranked as the most preferred option and chosen by 42 individual consumers (39%; 95% CI 29% to 48%). Most clinicians based their choice on the ratio of patients benefiting from ET, while consumers considered the absolute number of patients benefiting. Consumers favor maximization of the absolute number achieving good outcome in comparison with clinicians. This finding suggests that less restrictive criteria may be favored in clinical practice. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    We have previously shown that sympathetic ganglia stimulation via the renal vein rapidly increases blood pressure. This study further investigated the optimal target sites and effective energy levels for stimulation of the renal vasculatures and nearby sympathetic ganglia for rapid increase in blood pressure. The pre-study protocol for endovascular stimulations included 2 minutes of stimulation (1-150 V and 10 pulses per second) and at least 2 minutes of rest during poststimulation. If blood pressure and/or heart rate were changed during the stimulation, time to return to baseline was allowed prior to the next stimulation. In 11 acute canine studies, we performed 85 renal artery, 30 renal vein, and 8 hepatic vasculature stimulations. The mean arterial pressure (MAP) rapidly increased during stimulation of renal artery (95 ± 18 mmHg vs. 103 ± 15 mmHg; P vein (90 ± 16 mmHg vs. 102 ± 20 mmHg; P = 0.001), and hepatic vasculatures (74 ± 8 mmHg vs. 82 ± 11 mmHg; P = 0.04). Predictors of a significant increase in MAP were energy >10 V focused on the left renal artery, bilateral renal arteries, and bilateral renal veins (especially the mid segment). Overall, heart rate was unchanged, but muscle fasciculation was observed in 22.0% with an output >10 V (range 15-150 V). Analysis after excluding the stimulations that resulted in fasciculation yielded similar results to the main findings. Stimulation of intra-abdominal vasculatures promptly increased the MAP and thus may be a potential treatment option for hypotension in autonomic disorders. Predictors of optimal stimulation include energy delivery and the site of stimulation (for the renal vasculatures), which informs the design of subsequent research. © 2016 Wiley Periodicals, Inc.

    We report a case of a ruptured left atrial myxoma with multiple synchronous sites of embolization, including the intracranial cerebral (left middle cerebral artery (MCA) and basilar), visceral (renal, superior mesenteric artery (SMA)) and peripheral circulatory beds (aorta and lower extremities). This synchronous embolization resulted in a catastrophic neurologic and systemic event. An intracranial stent retriever was used to restore cerebral circulation in the symptomatic left MCA distribution, which resulted in resolution of the acute neurologic deficits. Endovascular and open surgical interventions were later performed to address the residual cardiac mass and other embolic sites. The patient survived the event with the loss of her right leg below the knee and a transient dialysis requirement. The purpose of this case report is to document the successful utilization of a stent-retriever device in removing an embolized myxoma from the cerebral circulation, to review the unique pathology of this source of embolic stroke and to reiterate the importance of considering embolic and non-thrombotic etiologies of acute ischemic stroke, especially in atypical patient populations and patient presentations. © The Author(s) 2016.

    5 recent trials have shown the benefit of endovascular treatment for acute ischaemic stroke (AIS) due to large vessel occlusion of the anterior circulation. This study aims to evaluate the safety and efficacy of Solitaire thrombectomy in patients with moderate-to-severe stroke in the Chinese population, which has a high prevalence of intracranial atherosclerosis. This multicentre prospective control study will involve 17 stroke centres in China, and plans to recruit 150 patients in the intervention group, and 150 patients in the medical group, in which patients meet enrolment criteria but refuse intervention. Patients with AIS due to large vessel occlusion indicated for treatment with Solitaire stent retriever within 12 hours of symptom onset, and who meet the inclusion and exclusion criteria, will be enrolled in this study. The primary efficacy endpoint is functional independence as defined by a modified Rankin Scale (mRS) score ≤2 at 90 days or by functional improvement as defined by mRS, using shift analysis. The procedural efficacy endpoint is arterial recanalisation of the occluded target vessel measured by a modified Thrombolysis in Cerebral Infarction (mTICI) score equal or superior to 2b right following the use of the study device. The primary safety endpoint is symptomatic intracranial haemorrhage (sICH) within 24±3 hours postprocedure. The protocol was approved by the Ethics Committee at the coordinating centre and by the local Institutional Review Board of each participating centre. NCT02350283.

    Endovascular therapy is favored for ruptured intracranial aneurysms in the elderly. However, poor accessibility to the aneurysm through the parent artery and use of local anesthesia in this age group may predispose to intraprocedural complications. To evaluate whether age-related poor access to the ruptured target aneurysm and use of local anesthesia are associated with increased incidence of procedure-related rupture during endovascular embolization. A total of 117 patients with 117 ruptured aneurysms underwent endovascular embolization at a single institution. Correlation of increasing age with poor accessibility of the guiding catheter was analyzed. In addition, the distance from the aneurysm to the guiding catheter was investigated to identify an association with incidence of procedure-related rupture. Correlation of local anesthesia with procedure-related rupture was also evaluated in the multivariable analysis. Increasing age was significantly associated with poor accessibility of the guiding catheter (P = .001, Mann-Whitney U test). Procedure-related rupture occurred in 9 of 117 aneurysms (7.7%). Longer distance between distal aneurysms and low-positioned guiding catheters carried a higher risk of procedure-related rupture than a shorter distance between proximal aneurysms and high-positioned guiding catheters (odds ratio, 19.3; 95% confidence interval, 1.84-201; P = .01, multivariable analysis). Use of local anesthesia was also a significant risk factor of procedure-related rupture by multivariable analysis. Increasing age was correlated with poor accessibility of the guiding catheter in endovascular embolization of ruptured intracranial aneurysms. Distally located aneurysms treated through a low-positioned guiding catheter and use of local anesthesia increased the risk of procedure-related rupture.

    2013-01-01

    We sought to identify and describe the number, topics, and publishing trends of systematic reviews relevant to occupational therapy indexed in the OTseeker database. We performed a cross-sectional survey of the systematic reviews contained in OTseeker in December 2011. Of the 1,940 systematic reviews indexed in OTseeker, only 53 (2.7%) were published in occupational therapy journals. The most common diagnostic categories were stroke (n = 195, 10.1%) and affective disorders (n = 204, 10.5%). The most common intervention categories were consumer education (n = 644, 33.2%) and psychosocial techniques (n = 571, 29.4%). Only 390 (20.1%) of the 1,940 systematic reviews specifically involved occupational therapy. Occupational therapists need to search broadly to locate relevant systematic reviews or, alternatively, to use databases such as OTseeker. Clarity about the involvement of occupational therapy in reports of future research will improve the ability to identify occupational therapy research for all stakeholders. Finally, occupational therapy practitioners need to read systematic reviews critically to determine whether review conclusions are justified.

    Full Text Available Spontaneous splenic haemorrahge and rupture is a rare but life-threatening condition requiring urgent diagnosis and treatment. Splenic haemorrhage and rupture precipitated by thrombolytic or antiocoagulant therapy has been reported frequently in the literature, but only two cases due to ticlopidine and one case due to salicyclate have been reported. We report the case of a 54-year-old man with haemorrhagic shock due to spontaneous splenic haemorrhage and rupture following dual antiplatelet (aspirin and clopidogrel therapy. He was successfully treated with selective angioembolization of the bleeding branch of the splenic artery.

    The International Classification of Headache Disorders (ICHD-3 beta) includes headache attributed to intracranial endovascular procedures (EVPs). The aim of this review is to describe the clinical and pathophysiological aspects of headache related to vascular lesions and EVPs. Current studies regarding this issue are contradictory, although generally favouring headache improvement after EVPs. Further large studies are needed to adequately assess the effect of EVPs on headache.

    Full Text Available To present the various techniques used in the management of pancreatitis-related pseudoaneurysms of visceral vessels.The retrospective clinical study was carried out at the Department of Diagnostic and Interventional Radiology at Poznan University of Medical Sciences from 2011 to 2016. The fifteen patients included in the study were diagnosed with pseudoaneurysms of visceral arteries, as a complication of chronic pancreatitis. The diagnosis was made using contrast-enhanced computed tomography, followed by angiography. On admission, all patients were symptomatic, with varying degrees of abdominal pain. One patient was haemodynamically unstable. Treatments with endovascular techniques were analysed, along with their efficacy and outcomes. Coil embolisation was performed in 5 patients. Stent graft was used in 1 patient. Liquid embolic agents were used in 7 cases, of which 5 patients were treated with thrombin injection and 2 with Squid. A combination of techniques was used in 2 patients.The most common artery affected by pseudoaneurysm formation was the splenic artery (7/15; 46.7%, and the size of the pseudoaneurysms ranged from 27 mm to 85 mm. Primary technical success was achieved in 14 out of 15 patients (93.3%. One patient required reintervention. Two patients required splenectomy after embolisation due to splenic ischemia. No recanalisation was present at the follow-up computed tomography performed after 1 to 3 weeks, and no mortality was observed within 30 days.Vascular complications of pancreatitis require accurate diagnosis and immediate treatment. Endovascular intervention is highly effective and is the preferred treatment option. The technique used is determined based on vascular anatomy and the patient's haemodynamic status.

    Charcot neuroarthropathy is a low-incidence complication of diabetic foot and is associated with ankle and hind foot deformity. Patients who have not developed deep ulcers are managed with offloading and supportive bracing or orthopedic arthrodesis. In patients who have developed ulcers and severe ankle instability and deformity, below-the-knee amputation is often indicated, especially when deformity and cutaneous involvement result in osteomyelitis. Ischemic association has not been described but can be present as a part of peripheral arterial disease in the diabetic population. In this extreme and advanced stage of combined neuroischemic diabetic foot disease, revascularization strategies can support surgical and orthopedic therapy, thus preventing osteomyelitis and leading to limb and foot salvage.

    Full Text Available Background: The requirements for a comprehensive stroke center (CSC include the capability to perform endovascular stroke therapy (EST. EST is a complex process requiring early identification of appropriate patients and effective delivery of intervention. In order to provide prompt intervention for stroke, CSCs have been established away from large academic centers in community-based hospitals. We hypothesized that quantifiable improvements would occur during the first 2 years of a community-based CSC as the processes and personnel evolved. We report the results over time of EST at a new community-based CSC. Methods: We have retrospectively analyzed demographic data and outcome metrics of EST from the initiation phase of a new community-based CSC. Data was divided into year 1 and year 2. Statistical analysis (Student's t test and Fisher's exact test was performed to compare the patient population and outcomes across the two time periods. Outcome variables included the thrombolysis in cerebral infarction (TICI score, a change in the NIH stroke scale score and the modified Rankin Scale (mRS score. Analysis of variance (ANOVA was used to statistically analyze the relationship between population variables and outcome. Computed tomography (CT angiography and CT perfusion analysis were used to select patients for EST. Approximately half of the patients undergoing EST were excluded from receiving intravenous recombinant tissue plasminogen activator (IV rt-PA by standard criteria, while the other half showed no sign of improvement following 1 h of IV rt-PA treatment. Mechanical thrombolysis with a stentriever was performed in the majority of cases with or without intra-arterial medication. The majority of treated occlusions were in the middle cerebral artery. Results: A total of 18 patients underwent EST during year 1 and year 2. A statistically significant increase in good outcomes (mRS score ≤2 at discharge was seen from year 1 to year 2 (p = 0

    Purpose. To establish the efficacy and safety of the preclose technique in total percutaneous endovascular aortic repair (PEVAR).MethodsA systematic literature search of Medline database was conducted for series on PEVAR published between January 1999 and January 2012.ResultsThirty-six articles comprising 2,257 patients and 3,606 arterial accesses were included. Anatomical criteria used to exclude patients from undergoing PEVAR were not uniform across all series. The technical success rate was 94 % per arterial access. Failure was unilateral in the majority (93 %) of the 133 failed PEVAR cases. The groin complication rate in PEVAR was 3.6 %; a minority (1.6 %) of these groin complications required open surgery. The groin complication rate in failed PEVAR cases converted to groin cutdown was 6.1 %. A significantly higher technical success rate was achieved when arterial access was performed via ultrasound guidance. Technical failure rate was significantly higher with larger sheath size (≥20F). Conclusion. The preclose technique in PEVAR has a high technical success rate and a low groin complication rate. Technical success tends to increase with ultrasound-guided arterial access and decrease with larger access. When failure occurs, it is unilateral in the majority of cases, and conversion to surgical cutdown does not appear to increase the operative risk.

    Treatment of thoracic aortic pathology is complicated by the morbidity associated to the surgical procedure and to the frailty of an elderly and difficult population. Surgical operation in this kind of population frequently bears a significant incidence of death and long-term disability. In an effort to reduce the incidence of negative outcomes, minimally invasive techniques in the form of endovascular stenting have been introduced during the past decade. The technology, originally described by Parodi, and initially designed for its use in abdominal aortic aneurysms, has been adapted for the treatment of thoracic aortic aneurysms. Furthermore, an improved understanding of the pathophysiology and the natural history of thoracic aortic disease as well as the analysis of the outcomes have facilitated our treatment decisions in terms of the timing for an appropriate intervention. Treatment of thoracic aortic dissection using endovascular Stent is one of the more recent advances in this condition and is receiving increasing attention, as it is a less invasive alternative to an open surgical repair. Although this technology is still innovative, significant improvements have been made lately in the design and deployment of the endovascular Stent-grafts. These prostheses have been increasingly used to treat aneurysms, dissections and traumatic ruptures, as well as giant penetrating ulcers and intramural hematomas of the descending thoracic aorta with good early and mid-term outcomes. The rareness, complexity and severity of the pathology and the theoretically high risk of complications should render the surgeon extremely cautious especially with young patients. Conceptually, the endo luminal treatment in the acute phase seems to be the solution and will probably become a preferred therapy while technical refinement is under way. Worldwide experience is growing and with this a better understanding of the indications and limitations of this innovative therapy will be

    Venous thromboembolism (VTE) is associated with substantial morbidity and mortality. Conventional treatment with anticoagulation therapy may undertreat the condition. Patients with VTE are at risk for recurrence with increasing time passage. Endovascular approaches exist for treating VTE, including deep vein thrombosis, but it is unclear which patients are appropriate candidates for endovascular versus medical approaches. Many new endovascular technologies are in development, and new oral anticoagulants are also on the market. Clinicians must be mindful of these new products and use them appropriately to better manage VTE. Copyright © 2014 Elsevier Inc. All rights reserved.

    Endovascular treatment of aneurysms of the posterior inferior cerebellar artery (PICA) avoids manipulation of the brainstem or lower cranial nerves and should therefore carry a lower risk of neurological morbidity than surgical clipping. We reviewed our experience of 23 patients with PICA aneurysms treated by endovascular occlusion with Guglielmi detachable coils and documented their long-term outcome on follow-up. We observed a 28 day procedure-related neurological morbidity of 13% (3/23 patients). One patient suffered permanent neurological complications. There were no procedure-related deaths. None of our patients suffered a re-bleed from their treated aneurysms. Our series shows endovascular treatment of ruptured PICA aneurysms to be safe and effective. (orig.)

    Ruptured intracranial dissecting aneurysms must be secured quickly to prevent re-hemorrhage. Endovascular sacrifice of the diseased segment is a well-established treatment method, however postoperative outcomes of symptomatic stroke and re-hemorrhage rates are not well reported, particularly for the perforator-rich distal vertebral artery or proximal posterior inferior cerebellar artery (PICA). We retrospectively reviewed cases of ruptured distal vertebral artery or PICA dissecting aneurysms that underwent endovascular treatment. Diagnosis was based on the presence of subarachnoid hemorrhage on initial CT imaging and of a dissecting aneurysm on catheter angiography. Patients with vertebral artery aneurysms were selected for coil embolization of the diseased arterial segment based on the adequacy of flow to the basilar artery from the contralateral vertebral artery. Patients with PICA aneurysms were generally treated only if they were poor surgical candidates. Outcomes included symptomatic and asymptomatic procedure-related cerebral infarction, recurrent aneurysm rupture, angiographic aneurysm recurrence, and estimated modified Rankin Scale (mRS). During the study period, 12 patients with dissecting aneurysms involving the distal vertebral artery (n=10) or PICA (n=2) were treated with endovascular sacrifice. Two patients suffered an ischemic infarction, one of whom was symptomatic (8.3%). One patient (8.3%) died prior to hospital discharge. No aneurysm recurrence was identified on follow-up imaging. Ten patients (83%) made a good recovery (mRS ≤2). Median clinical and imaging follow-up periods were 41.7 months (range 0-126.4 months) and 14.3 months (range 0.03-88.6 months), respectively. In patients with good collateral circulation, endovascular sacrifice may be the preferred treatment for acutely ruptured dissecting aneurysms involving the distal vertebral artery.

    2011-01-01

    To review the diagnostic value of angiographic methods and the optimal timetable for follow-up imaging of patients after endovascular treatment of intracranial aneurysms. A comprehensive computer-aided search for relevant primary papers was performed using the MEDLINE, PubMed, Embase, and Cochrane Collaboration database from January 1991 to March 2011. Original papers were included that reported either diagnostic value of angiographic modalities for follow-up vs. digital subtracted angiography (DSA) or comparison of aneurysm occlusion rate in delayed vs. early follow-up. The systematic review identified 35 relevant studies: 3 on the diagnostic value of three-dimensional (3D) DSA, 30 on the performance of magnetic resonance angiography (MRA), and 3 on time schedules for follow-up. 3D DSA had sensitivity of 100%, and specificity of 58.3-94.7%. Magnetic resonance angiography had sensitivity of 28.4-100%, and specificity of 50.0-100%. The proportion of aneurysms that recanalized between the early follow-up examination at 6 months and the delayed imaging at 1.5-6.0 years was 0-2.5%. Magnetic resonance angiography seems to be the best imaging method for the follow-up. In selected cases, when invasive angiography is necessary, 3D DSA should be considered to improve the diagnostic accuracy. Most patients who present with stable and adequate aneurysm occlusion at 6 months after coiling may not require further follow-up. Key words: intracranial aneurysm, embolization, coils, digital subtracted angiography, magnetic resonance, computed tomography.

    To prospectively investigate predictors for good restoration of blood flow of below-the-knee (BTK) chronic total occlusions (CTOs) after endovascular therapy in diabetes mellitus (DM) patients. A total of 120 long-segmental (≥ 5 cm) BTK, CTOs in 81 patients who underwent recanalization were included in this study. After angioplasty, blood-flow restoration was assessed using modified thrombolysis in myocardial ischemia grades and classified as good flow (grade 3) and poor flow (grade 1/2). One hundred and six CTOs with successful recanalization were divided into a good flow group (GFG; n = 68) and poor flow group (PFG; n = 38). Multivariate logistic regression analyses were undertaken to determine independent predictors of blood-flow restoration. Receiver operating characteristic curves were constructed to determine the best cutoff value. The prevalence of target-lesion restenosis during follow-up was compared between two groups. Univariate analyses suggested that CTOs in GFG were characterized by lighter limb ischemia (p = 0.03), shorter course of ischemic symptoms (p < 0.01) and lesion length (p = 0.04), more frequent use of intraluminal angioplasty (p = 0.03), and higher runoff score (p < 0.01) than those in PFG. Multivariate regression analyses suggested that distal runoffs (p = 0.001; odds ratio [OR], 10.32; 95% confidence interval [CI]: 4.082-26.071) and lesion length (p < 0.001; OR, 1.26; 95% CI: 1.091-1.449) were independent predictors for good flow restoration. Kaplan-Meier analyses at 12 months showed a higher prevalence of non-restenosis in GFG (p < 0.01). Distal runoffs and lesion length are independent predictors for good flow restoration for long-segmental BTK, CTOs in DM patients who receive endovascular therapy.

    2012-01-01

    Full Text Available Distal superior cerebellar artery (SCA aneurysms are rare. Fusiform aneurysms of SCA are rarer and more challenging to treat. Parent artery occlusion by endovascular coiling is the treatment option for these cases. Presence of good collateral circulation and paucity of perforators from S1 and S2 segments makes this a feasible option. From 2007 to 2010, we treated three patients (two men and one woman between the ages of 42 to 64 years with distal fusiform SCA aneurysms using endovascular coiling. All the patients presented with symptoms of rupture and were treated in the acute phase. Informed and written high-risk consent was given by all patients prior to the procedure. Successful angiographic and clinical outcome was achieved in all three patients. Endovascular treatment of fusiform SCA aneurysms with coils is a safe and feasible option in the management of this rare entity.

    Pre-treatment collateral status may be associated with the rates of successful revascularization in acute ischemic stroke patients receiving endovascular treatment (EVT). We conducted a systematic review and meta-analysis to synthesize relevant evidence currently available. Relevant full-text articles published in English since January 1, 2000, reporting associations between collateral status and successful reperfusion and/or recanalization in acute ischemic stroke patients receiving EVT in cohort or case-control studies, or randomized clinical trials, were retrieved through search of PubMed. Study selection, data extraction and study quality assessment were carried out by 2 investigators. Risk ratios (RR) were pooled for good vs. poor collaterals for the outcomes of successful reperfusion and recanalization, based on random-effects models. Subgroup analyses were conducted to explore for potential factors that might interfere with the effects of pre-treatment collateral status on reperfusion by EVT. In total, 27 studies (2,366 subjects) were included in qualitative analysis, among which 24 studies (2,239 subjects) were quantitatively analyzed. Overall, good pre-treatment collaterals significantly increased the rate of both successful reperfusion (RR 1.28, 95% CI 1.17-1.40; p collaterals. Subgroup analyses revealed that the effects of collateral status on successful reperfusion by EVT might be different between populations with different ethnicities. Good pre-treatment collaterals may enhance the rates of successful reperfusion and recanalization in EVT for acute ischemic stroke. This may partly explain the favorable effects of good pre-treatment collaterals on clinical outcomes of stroke patients receiving EVT. Thus, it would be valuable to assess the collateral status prior to EVT in acute ischemic stroke. But studies are needed to further verify if the positive effects of good collaterals on revascularization by EVT are restricted to certain subgroups of patients

    We report the follow-up of a previously published case (Forlodou et al. Neuroradiology 38:595-597, 1996) of carotido-cavernous fistulas (CCFs) in a patient presenting with type IV Ehlers-Danlos syndrome (EDS 4) that were successfully treated twice by an endovascular approach. Initial treatment with a detachable balloon was in 1994 for a right CCF, and, 8 years later, a left CCF was treated by selective transarterial occlusion of the cavernous sinus with coils. Unfortunately, the patient suffered from a spontaneous post-operative intracranial haemorrhage in the left hemisphere and died. Review of the literature, technical considerations for bilateral CCF and complication are discussed.

    To develop a scoring system to predict wound healing in critical limb ischemia (CLI) patients treated with endovascular therapy (EVT). Between July 2007 and January 2013, 184 patients (118 men; mean age 73.0 years) with CLI (217 limbs) and tissue loss underwent EVT. From this cohort 236 separate wounds were divided into development (n = 118) and validation (n = 118) groups. Predictors of wound healing were identified using multivariable analysis. Each predictor was assigned a score based on its regression coefficient, and total scores were calculated, ranging from 0 to 1 for low risk up to ≥ 4 for high risk of a nonhealing wound. The performance of the scoring system in the prediction of wound healing was evaluated by calculating the area under the receiver operating characteristics (ROC) curve. By multivariable analysis, a University of Texas grade ≥ 2 (HR 0.524, 95% CI 0.288-0.951, p = 0.034), an infected wound (HR 0.497, 95% CI 0.276-0.894, p = 0.020), dependence on hemodialysis (HR 0.459, 95% CI 0.259-0.814, p = 0.008), no visible blood flow to the wound (HR 0.343, 95% CI 0.146-0.802, p = 0.014), and major tissue loss (HR 0.322, 95% CI 0.165-0.630, p = 0.001) predicted a non-healing wound. The 1-year rates of wound healing in the low-, intermediate-, and high-risk groups were 94.6%, 67.6%, and 9.1%, respectively, in the development group (p wound healing in CLI patients after endovascular revascularization and is potentially helpful in deciding if additional adjuncts or revascularization should be considered. © The Author(s) 2015.

    Full Text Available In the past twenty years we have witnessed a revolution in the treatment of intracranial aneurysms. Endovascular technique and materials have rapidly developed since the approval of Guglielmi detachable coils in 1995 which now allow successful treatment of most aneurysms. The development of intracranial stents and balloons for stent-assisted coiling and balloon-remodeling technique further expanded the spectrum of aneurysms treatable with endovascular technique. For these reasons, the aim of this review was to describe endovascular technique and materials which we use in our daily practice, to show benefits of endovascular treatment and to discus complications of endovascular treatment and surgical treatment of intracranial aneurysms. Endovascular treatment is more comfortable for the patient not only because it is minimally invasive but also because it does not require long hospitalization equal to that after surgical treatment. It is a fact that with further development of endovascular materials, this a procedure will have even a more significant place in the treatment of intracranial aneurysms.

    Endovascular therapies (intra-arterial thrombolysis and mechanical thrombectomy) after acute ischaemic stroke are being implemented in the clinical setting even as they are still being researched. Since we lack sufficient data to establish accurate evidence-based recommendations for use of these treatments, we must develop clinical protocols based on current knowledge and carefully monitor all procedures. After review of the literature and holding work sessions to reach a consensus among experts, we developed a clinical protocol including indications and contraindications for endovascular therapies use in acute ischaemic stroke. The protocol includes methodology recommendations for diagnosing and selecting patients, performing revascularisation procedures, and for subsequent patient management. Its objective is to increase the likelihood of efficacy and treatment benefit and minimise risk of complications and ineffective recanalisation. Based on an analysis of healthcare needs and available resources, a cooperative inter-hospital care system has been developed. This helps to ensure availability of endovascular therapies to all patients, a fast response time, and a good cost-to-efficacy ratio. It includes also a prospective register which serves to monitor procedures in order to identify any opportunities for improvement. Implementation of endovascular techniques for treating acute ischaemic stroke requires the elaboration of evidence-based clinical protocols and the establishment of appropriate cooperative healthcare networks guaranteeing both the availability and the quality of these actions. Such procedures must be monitored in order to improve methodology. Copyright © 2012 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

    Full Text Available Mechanical removal of the biofilm and adjunctive use of antibacterial disinfectants or various antibiotics have been conventional methods of the periodontitis therapy. There has been an upsurge of bacterial strains becoming resistant due to the injudicious use of antibiotics, recently. As a result there is pronounced interest and keenness in the development of alternate antimicrobial concepts. As the scientific community seeks alternatives to antibiotic treatment, periodontal researchers have found that photodynamic therapy (PDT is advantageous to suppress anaerobic bacteria. Hence, PDT could be an alternative to conventional periodontal therapeutic methods. This review elucidates the evolution and use of photo dynamic therapy. The application of photosensitizing dyes and their excitation by visible light enables effective killing of periodontopathogens. Even though PDT is still in the experimental stages of development and testing, the method may be an adjunct to conventional antibacterial measures in periodontology. PDT application has an adjunctive benefit besides mechanical treatment at sites with difficult access. Necessity for flap operations may be reduced, patient comfort may increase and treatment time decrease. Clinical follow-up studies are needed to confirm the efficacy of the procedure.

    The portal vein is formed at the confluence of the splenic and superior mesenteric vein behind the head of the pancreas. Normal blood pressure within the portal system varies between 5 and 10 mmHg. Portal hypertension is defined when the gradient between the portal and systemic venous blood pressure exceeds 5 mmHg. The most common cause of portal hypertension is cirrhosis. In cirrhosis, portal hypertension develops due to extensive fibrosis within the liver parenchyma causing increased vascular resistance. In addition, the inability of the liver to metabolise certain vasodilators leads to hyperdynamic splanchnic circulation resulting in increased portal blood flow. Decompression of the portal pressure is achieved by formation of portosystemic collaterals. In this review, we will discuss the pathophysiology, anatomy, and imaging findings of spontaneous portosystemic collaterals and clinical manifestations of portal hypertension with emphasis on the role of interventional radiology in the management of complications related to portal hypertension

    Purpose: Colonoscopy is reported to be a safe procedure that is routinely performed for the diagnosis and treatment of colorectal diseases. Splenic rupture is considered to be a rare complication with high mortality and morbidity that requires immediate diagnosis and management. Nonoperative management (NOM), surgical treatment (ST), and, more recently, proximal splenic artery embolization (PSAE) have been proposed as treatment options. The goal of this study was to assess whether PSAE is safe even in high-grade ruptures. Methods: We report two rare cases of post colonoscopy splenic rupture. A systematic review of the literature from 2002 to 2010 (first reported case of PSAE) was performed and the three types of treatment compared. Results: All patients reviewed (77 of 77) presented with intraperitoneal hemorrhage due to isolated splenic trauma. Splenic rupture was high-grade in most patients when grading was possible. Six of 77 patients (7.8 %) were treated with PSAE, including the 2 cases reported herein. Fifty-seven patients (74 %) underwent ST. NOM was attempted first in 25 patients with a high failure rate (11 of 25 [44 %]) and requiring a salvage procedure, such as PSAE or ST. Previous surgery (31 of 59 patients), adhesions (10 of 13), diagnostic colonoscopies (49 of 71), previous biopsies or polypectomies (31 of 57) and female sex (56 of 77) were identified as risk factors. In contrast, splenomegaly (0 of 77 patients), medications that increase the risk of bleeding (13 of 30) and difficult colonoscopies (16 of 51) were not identified as risk factors. PSAE was safe and effective even in elderly patients with comorbidities and those taking medications that increase the risk of bleeding, and the length of the hospital stay was similar to that after ST. Conclusion: We propose a treatment algorithm based on clinical and radiological criteria. Because of the high failure rate after NOM, PSAE should be the treatment of choice to manage grade I through IV splenic

    Variability in response to clopidogrel therapy is increasingly being recognized as an important factor in thromboembolic and hemorrhagic complications encountered after neurointerventional procedures. This study aims to determine the variability in response to clopidogrel therapy and associated complications in patients undergoing endovascular treatment of unruptured cerebral aneurysms. We recorded baseline patient characteristics, co-administered medications, P2Y12 reaction units (PRU) values with VerifyNow, clopidogrel dosing, and thromboembolic and hemorrhagic complications in patients undergoing endovascular treatment of unruptured cerebral aneurysms at our institution during a 19 month period. 100 patients were included in the study, 76 women and 24 men, mean age 57.3 years. 15 patients exhibited an initial clopidogrel hypo-response (PRU >240) and 21 patients an initial clopidogrel hyper-response (PRU <60). 36 patients had a follow-up VerifyNow test performed without changes to the standard 75 mg daily clopidogrel dose, which demonstrated that 59% of patients who had initially been within the target 60-240 PRU range exhibited a delayed conversion to clopidogrel hyper-response. In our cohort, a clopidogrel hypo-response was associated with a significantly increased risk of thromboembolic complications in patients undergoing cerebral aneurysm treatment with stent assistance or the pipeline embolization device (60%, p=0.003), while a clopidogrel hyper-response was associated with a significantly increased risk of major hemorrhagic complications in all patients undergoing endovascular treatment of cerebral aneurysms (11%, p=0.016). We found wide and dynamic variability in response to clopidogrel therapy in patients undergoing endovascular treatment of unruptured cerebral aneurysms, which was significantly associated with thromboembolic and major hemorrhagic complications in our cohort.

    As part of a project to devise evidence-based safety interventions for specialty surgery, the authors sought to review current evidence in endovascular neurosurgery concerning the frequency of adverse events in practice, their patterns, and current methods of reducing the occurrence of these events. This review represents part of a series of papers written to consolidate information about these events and preventive measures as part of an ongoing effort to ascertain the utility of devising system-wide policies and safety tools to improve neurosurgical practice. Based on a review of the literature, thromboembolic events appeared to be the most common adverse events in endovascular neurosurgery, with a reported incidence ranging from 2% to 61% depending on aneurysm rupture status and mode of detection of the event. Intraprocedural and periprocedural prevention and rescue regimens are advocated to minimize this risk; however, evidence on the optimal use of anticoagulant and antithrombotic agents is limited. Furthermore, it is unknown what proportion of eligible patients receive any prophylactic treatment. Groin-site hematoma is the most common access-related complication. Data from the cardiac literature indicate an overall incidence of 9% to 32%, but data specific to neuroendovascular therapy are scant. Manual compression, compression adjuncts, and closure devices are used with varying rates of success, but no standardized protocols have been tested on a broad scale. Contrast-induced nephropathy is one of the more common causes of hospital-acquired renal insufficiency, with an incidence of 30% in high-risk patients after contrast administration. Evidence from medical fields supports the use of various preventive strategies. Intraprocedural vessel rupture is infrequent, with the reported incidence ranging from 1% to 9%, but it is potentially devastating. Improvements in device technology combined with proper endovascular technique play an important role in reducing

    Objective: To explore the methods of early etiological diagnosis and principles of endovascular embolization in Hunt-Hess IV-V grade subarachnoid hemorrhage (SAH), and to evaluate the therapeutic efficacy. Methods: Thirty-one patients underwent imaging examinations such as CT and DSA to make the early diagnosis of SAH. Meanwhile, Guglielmi detachable microcoil (GDC) was used to applying aneurysmal intracapsular embolization in the ruptured aneurysms, and efficient symptomatic treatment was adopted early postoperatively. The results were tested by χ 2 test. Results: All 31 cases were diagnosed early and operated successfully. Among them, the aneurysm lumen was 100% occluded in 26 cases, 95% occluded in 3 cases; 90% occluded in 2 cases. There were 5 cases complicating with cerebral vasospasm. One case recurrent was cured with secondary complementary GDC embolization. Nine cases (29.0%) had permanent sequelae associated with SAH. According to the Glasgow prognosis score, the therapeutic efficacy was as following: 6 patients were in grade I, 9 in grade II, 4 in grade III, 2 in grade IV, and 10 in grade V; 10 patients died, and the morality rate was 32.3%. None of them exhibited re-bleeding with follow-up period of 3 to 68 months postoperatively. Morality rates were significantly different between the group with aneurysmal diameter of 11-25 mm and the group of 5-10 mm (χ 2 =6.60, P 2 =11.24, P 2 =6.35, P<0.05). Conclusions: CT and DSA can make the early etiological diagnosis of the Hunt-Hess IV-V grade aneurysmal SAH, and GDC can be used early to perform the aneurysmal intracapsular embolization. Dealing with hemorrhage and using efficient symptomatic treatment earlier postoperatively are important methods to improve the curative rate and reduce the mortality rate and mutilation rate.

    Early judgment of long-term prognosis is the key to making medical decisions in acute anterior circulation large-vessel occlusion stroke (LVOS) after endovascular treatment (EVT). We aimed to investigate the relationship between the combination of 24-hour and 7-day relative neurological improvement (RNI) and 90-day functional outcome. We selected the target population from a multicenter ischemic stroke registry. The National Institutes of Health Stroke Scale (NIHSS) scores at baseline, 24 hours, and 7 days were collected. RNI was calculated by the following equation: (baseline NIHSS - 24-hour/7-day NIHSS)/baseline NIHSS × 100%. A modified Rankin Scale score of 0-2 at 90 days was defined as a favorable outcome. Multivariable logistic regression analysis was used to evaluate the relationship between RNI and 90-day outcome. Receiver operator characteristic curve analysis was performed to identify the predictive power and cutoff point of RNI for functional outcome. A total of 568 patients were enrolled. Both 24-hour and 7-day RNI were independent predictors of 90-day outcome. The best cutoff points of 24-hour and 7-day RNI were 28% and 42%, respectively. Compared with those with 24-hour RNI of less than 28% and 7-day RNI of less than 42%, patients with 24-hour RNI of 28% or greater and 7-day RNI of 42% or greater had a 39.595-fold (95% confidence interval 22.388-70.026) increased probability of achieving 90-day favorable outcome. The combination of 24-hour and 7-day RNI very strongly predicts 90-day functional outcome in patients with acute anterior circulation LVOS who received EVT, and it can be used as an early accurate surrogate of long-term outcome.

    Purpose: To study the initial and long-term results of angioplasty and primary stenting for the treatment of chronic total occlusion (CTO) of the subclavian artery (SA). Materials and Methods: From January 1999 to February 2010, 56 patients (25 men with a mean age of 58 ± 8 years) underwent endovascular treatment for CTO of the SA. Duplex scans and arteriograms confirmed occlusion in all cases. Indications for recanalization were subclavian steal syndrome in 33 patients (58.1%), arm claudication in 13 patients (23.2%), and coronary ischemia in 7 patients (12.5%) who had a history of previous coronary artery bypass grafting that included left internal thoracic artery graft. Three patients (5.4%) were treated before the scheduled coronary artery bypass surgery, which included left internal thoracic artery graft. After successful recanalization, all arteries were stented, and all of the patients were followed-up at 1, 3, 6, and 12 months after surgery and annually thereafter. Results: Successful recanalization of the SA was achieved in 46 patients (82.1%), and the complication rate was 7.1%. During follow-up (mean 40 ± 26 months; range 2 to 125), the primary patency rates after 1 and 3 years were 97.9% and 82.7%, respectively. At the end of follow-up, 76% of the arteries showed no evidence of restenosis. Univariate analysis failed to identify any variable predictive of long-term patency of successfully recanalized SA. Conclusion: Percutaneous transluminal angioplasty with stenting of the complete total occlusion of the SA is a safe and effective procedure associated with low risks and good long-term results.

  1. Endovascular repair of abdominal aortic aneurysm with severely angulated neck and tortuous artery access: case report and literature review.

    Endovascular aneurysm repair has revolutionized the therapeutic strategy for abdominal aortic aneurysm. However, hostile proximal aneurysmal neck and tortuosity of access vessels remain challenges in selecting optimal stent-grafts in abdominal aortic aneurysms with difficult anatomy. A 65-year-old woman complained of intermittent abdominal pain for one week. Computed tomography angiogram demonstrated a tortuous infrarenal abdominal aortic aneurysm with a tapered neck and a 136° of infrarenal angulation. Aneurysmal dilatation and severe calcification of bilateral iliac arteries and tortuous aortoiliac access were also showed. Endovascular approach using Endurant stent-graft was attempted at an outside hospital, but failed because of the significant tortuosity of the abdominal aorta and iliac arteries. Since the patient refused to have open aneurysm repair, he was transferred to our hospital for further evaluation and possible EVAR with a different approach. EVAR was performed successfully using Gore Excluder stent-grafts (W.L. Gore & Associates, Flagstaff, AZ, USA). During the procedure, cannulation of the contralateral limb was unable to be achieved because of the tortuous aortoiliac course. Therefore, a snare was inserted from right radial artery, through the contralateral gate, to grasp the wire from left femoral artery. Two iliac stent-grafts were sequentially deployed with the lower end distal to the opening of the left internal iliac artery. Angiography confirmed complete sealing of the aneurysm with patency of bilateral renal arteries and external iliac arteries. The postoperative courses were uneventful and follow-up computed tomography angiogram at 6 months demonstrated patent bilateral femoral and renal arteries without endoleaks or stent migration. Although endovascular repair of aortic aneurysm with hostile neck and tortuous access is rather challenging, choosing flexible stent-grafts and suitable techniques is able to achieve an encouraging outcome.

    Full Text Available Renal angiomyolipoma is a hamartomatous, benign tumor composed of blood vessels, fatty tissue and smooth muscle cells, and is often detected incidentally. It can also be associated with the tuberous-sclerosis complex (TSC. Pregnancy and use of oral contraceptives are known to be associated with an increased risk of tumoral rupture and bleeding. Herein, we report a unique case of renal angiomyolipoma associated with TSC who presented with hypovolemic shock as a result of spontaneous rupture of a giant renal pseudoaneurysm, immediately after pregnancy. Emergency endovascular treatment was successful with sparing of most of the affected kidney as demonstrated by follow-up computed tomography imaging.

    Background: Aneurysms of the anterior inferior cerebellar artery (AICA), especially those located in the distal portion of the AICA, are rare. There are few reported cases treated with surgery or endovascular embolization. Case Description: We report two cases of fusiform distal AICA aneurysms presenting with subarachnoid hemorrhage. Parent artery occlusion with coils and n-butyl cyanoacrilate (n-BCA) resulted in complete aneurysm occlusion and prevented rebleeding. Both patients presented postprocedure neurological deficits, but have made a good recovery at 4 and 10 months, respectively. Conclusion: Occlusion of the parent artery for the treatment of ruptured fusiform distal AICA aneurysms is effective but has significant neurological risks. PMID:21748047

    The objective of this study was to review the outcome of endovascular transcatheter repair of emergent arterioenteric fistulas. Cases of abdominal arterioenteric fistulas (defined as a fistula between a major artery and the small intestine or colon, thus not the esophagus or stomach), diagnosed over the 3-year period between December 2002 and December 2005 at our institution, were retrospectively reviewed. Five patients with severe enteric bleeding underwent angiography and endovascular repair. Four presented primary arterioenteric fistulas, and one presented a secondary aortoenteric fistula. All had massive persistent bleeding with hypotension despite volume substitution and transfusion by the time of endovascular management. Outcome after treatment of these patients was investigated for major procedure-related complications, recurrence, reintervention, morbidity, and mortality. Mean follow-up time was 3 months (range, 1-6 months). All massive bleeding was controlled by occlusive balloon catheters. Four fistulas were successfully sealed with stent-grafts, resulting in a technical success rate of 80%. One patient was circulatory stabilized by endovascular management but needed immediate further open surgery. There were no procedure-related major complications. Mean hospital stay after the initial endovascular intervention was 19 days. Rebleeding occurred in four patients (80%) after a free interval of 2 weeks or longer. During the follow-up period three patients needed reintervention. The in-hospital mortality was 20% and the 30-day mortality was 40%. The midterm outcome was poor, due to comorbidities or rebleeding, with a mortality of 80% within 6 months. In conclusion, endovascular repair is an efficient and safe method to stabilize patients with life-threatening bleeding arterioenteric fistulas in the emergent episode. However, in this group of patients with severe comorbidities, the risk of rebleeding is high and further intervention must be considered

    Peripheral anterior inferior cerebellar artery (AICA) aneurysms are rare, accounting for less than 1% of all cerebral aneurysms. To our knowledge 34 flow-related cases including the present study have been reported in the literature. Three patients harbouring four flow dependent aneurysms were referred to our institution. Two patients presented with subarachnoid hemorrhage, one presented with cerebellar manifestations. They were all treated by endovascular embolization of the aneurysm as well as the parent artery using liquid embolic material. Two cases were embolized using NBCA, Onyx was used in the third case. No bleeding or rebleeding were encountered during the follow-up period which ranged from five to nine months. One patient developed facial palsy, cerebellar symptoms and sensorineural hearing loss. The remaining two cases did not develop any post treatment neurological complications. Endovascular management of flow-dependent AICA aneurysms by parent artery occlusion is feasible and efficient in terms of rebleeding prevention. Post embolization neurological complications are unpredictable. This depends upon the adequacy of collaterals from other cerebellar arteries.

    Middle cerebral artery aneurysms (MCAAs) are regularly treated by both microsurgical clipping and endovascular coiling. We performed a systematic meta-analysis to compare the safety and efficacy of these 2 methods. Literature was reviewed for all studies reporting angiographic occlusion and/or functional outcomes in adults with unruptured MCAA treated by endovascular coiling or microsurgical clipping. All studies in English that reported results for adults (≥18 years) with unruptured MCAAs, from 1990 to 2011 were considered for inclusion. Twenty-six studies involving 2295 aneurysms treated with clipping or coiling for unruptured MCAAs were included for analysis. There were 1530 aneurysms that were treated with clipping and 765 aneurysms treated with coiling. Pooled analysis revealed failure of aneurysmal occlusion in 3.0% (95% confidence interval [CI] 1.2%-7.4%) of clipped cases. Pooled analysis of 15 studies (606 aneurysms) involving coiling and occlusion revealed lack of occlusion rates of 47.7% (95% CI 43.6%-51.8%) with the fixed-effects model and 48.2% (95% CI 39.0%-57.4%) with the random-effects model. Thirteen studies examined neurological outcomes after clipping and were pooled for analysis. Both fixed-effect and random-effect models revealed unfavorable outcomes in 2.1% (95% CI 1.3%-3.3%) of patients. There were 17 studies evaluating potential unfavorable neurological outcomes after coiling that were pooled for analysis. Fixed-effect and random-effect models revealed unfavorable outcomes in 6.5% (95% CI 4.5%-9.3%) and 4.9% (95% CI 3.0%-8.1%) of patients, respectively. Based on this systematic review and meta-analysis of unruptured MCAAs, after careful consideration of patient, aneurysmal, and treatment center factors, we recommend surgical clipping for unruptured MCAA.

    Objective: To evaluate the efficacy and risk of endovascular treatment for intracranial venous sinus thrombosis. Methods: Twenty seven patients with intracranial venous sinus thrombosis confirmed by CT, MRI, MRV and/or DSA, from 2004 September to 2006 September, were treated with anticoagulant therapy but without response and then followed by multiple modalities including endovascular treatment. Nineteen of them accepted intravenous thrombolysis and mechanical thrombus maceration, another 5 accepted intravenous thrombolysis, mechanical thrombus maceration and intraarterial thrombolysis and the last 3 with stenting. Results: After thrombolysis, symptoms and signs of 23 patients improved obviously and headache disappeared in 18 of them, but with only mild degree in other 5 and no improvement in 3. Twenty one patients among them achieved recanalization of sinuses completely as confirmed on postprocedural angiography, MRI and MRV studies taken prior to hospital discharge and other 3 achieved recanalization of sinuses partly. Conclusion: Endovascular treatment is an effective and safe measure for potentially catastrophic intracranial dural sinus thrombosis. (authors)

    Recently, several in vitro and in vivo studies demonstrated promising results about the use of photodynamic therapy during root canal system disinfection. However, there is no consensus on a standard protocol for its incorporation during root canal treatment. The purpose of this study was to summarize the results of research on photodynamic therapy in endodontics published in peer-reviewed journals. A review of pertinent literature was conducted using the PubMed database, and data obtained were categorized into sections in terms of relevant topics. Studies conducted in recent years highlighted the antimicrobial potential of photodynamic therapy in endodontics. However, most of these studies were not able to confirm a significant improvement in root canal disinfection for photodynamic therapy as a substitute for current disinfection methods. Its indication as an excellent adjunct to conventional endodontic therapy is well documented, however. Data suggest the need for protocol adjustments or new photosensitizer formulations to enhance photodynamic therapy predictability in endodontics.

    To evaluate the safety and efficacy of endovascular fiducial markers (EVFMs) for CyberKnife stereotactic radiation therapy (RT) of malignant lung neoplasms in patients with contraindications to percutaneous fiducial marker (PTFM) placement. Between January 2011 and December 2013, 15 patients (7 men and 8 women) aged 59-87 years (mean, 73 y) underwent EVFM placement and 109 patients (54 men and 55 women) aged 55-92 years (mean, 73 y) underwent 114 PTFM placements. All patients who received EVFMs had contraindications to PTFM insertion. Complications were recorded for all 129 procedures. Proportions of markers used for CyberKnife stereotactic RT planning and distance between markers and tumor were assessed in all 15 patients in the EVFM group and in 15 randomly selected patients in the PTFM group. Sixty-two EVFMs and 56 PTFMs were inserted in the groups of 15 patients. CyberKnife stereotactic RT was not performed in 2 EVFM recipients (8 EVFMs) and 1 PTFM recipient (4 PTFMs). CyberKnife stereotactic RT was planned with the use of 39 of 54 EVFMs (72%) in 13 patients and 37 of 52 PTFMs (71%) in 14 patients. Mean distances between the tumor and EVFMs and PTFMs were 5.5 mm and 2.7 mm, respectively (P = .0152). No complications occurred in the EVFM group. In the PTFM group, 60 of 114 patients (52.6%) had small or moderate pneumothoraxes, 13 (11.4%) had chest tubes inserted, and 5 (4.4%) had self-limiting hemoptysis. EVFM is feasible and safe, and may therefore offer an alternative when patients are not candidates for percutaneous marker placement. Copyright © 2017 SIR. Published by Elsevier Inc.

    To assess the safety and efficacy of carbon dioxide (CO2) angiography-guided endovascular therapy (EVT) for renal, iliofemoral artery disease. Patients with peripheral vascular disease (PVD) often have chronic kidney disease (CKD) and the use of iodinated contrast media may enhance the risk of contrast-induced nephropathy (CIN). Contrast volume reduction is an effective CIN preventive strategy. A prospective multicenter registry was developed and six clinical centers participated in the study. Patients with an estimated glomerular filtration rate (eGFR) of CO2 angiography-guided EVT was performed; incomplete CO2 angiograms were supplemented by intravascular ultrasound, pressure wire, and/or minimal iodinated contrast media. The primary endpoint was a composite of freedom from renal events and freedom from major CO2 angiography related complications. This study included 98 patients with 109 lesions. The mean eGFR baseline was 35.2±12.7 ml min(-1). CO2 angiography-guided angioplasty were performed in 16 renal arteries, 31 aortoiliac arteries, and 62 superficial femoral arteries. The technical success rate was 97.9%. Average CO2 consumption was 281.4±155.8 ml, average dose of iodinated contrast media was 15.0±18.1 ml. Primary endpoint was 92.8% (91/98). Incidence of CIN was 5.1% (5/98) and CO2 angiography-related complications occurred in 17.3% (17/98). Two cases (2%) developed severe, fatal, nonocclusive mesenteric ischemia (NOMI). This trial showed that CO2 angiography-guided angioplasty was effective for preventing CIN, however, CO2 angiography related complication was somewhat high. © 2014 Wiley Periodicals, Inc.

    Highlights: • FDCT provides cross-sectional images of the intraluminal devices. • Contrast agent administration enables the evaluation of the surrounding vessels. • Artefacts generated by the coil mass are the major limitation of this imaging tool. • MAR software improves significantly the quality of the acquired images. • The examination can be performed during the procedure as well as in the follow-up. - Abstract: Flat detector CT (FDCT) provides cross sectional imaging within an angiographic suite and is increasingly gaining popularity in various areas of interventional radiology, as an alternative imaging modality. Its relatively high spatial resolution improves visualization of intraluminal devices such as intracranial stents or flow-diverters. Device deployment and positioning, in relation to the parent vessel and surrounding structures, are easily assessible with FDCT. Furthermore, with contrast agent administration, it expands the diagnostic capabilities of this new imaging tool. However, beam-hardening artifacts is a major limitation in some cases. The examination can be performed both during the endovascular procedure and for pre- and post-treatment imaging. Intravenous contrast agent injection reduces the risk of complications, making it possible to perform this examination in the outpatient settings. The aim of this paper is to present an overview of published studies reporting experience with FDCT in the field of endovascular neurosurgery and in particular, FDCT's contribution in treatment of wide-necked intracranial aneurysms. The authors have focused specifically on stent-assisted coiling and flow-diverter implantation, since obtaining proper parent vessel wall apposition of these devices is essential for short- and long-term procedural outcomes.

    Gene therapy is the use of DNA as an agent to treat disease. Gene therapy aims at the insertion of a functional gene into the cells of a patient for the correction of an inborn error of metabolism, to alter or repair an acquired genetic abnormality, and to provide new function to the cell. Many experiments have been done with respect to its application in various diseases.Today, most of the gene therapy studies are aimed at cancer and hereditary diseases which are linked to genetic defects. Cancer usually occurs due to the production of multiple mutations in a single cell which cause it to proliferate out of control. Several methods such as surgery, radiation therapy and chemotherapy have been used widely to treat cancers. But, the cancer patients who are not helped by these therapies can be treated by gene therapy. The purpose of this article is to review the use and purpose of gene therapy in oral cancer.

    Full Text Available Three recently published trials, MR RESCUE, IMS III, and SYNTHESIS Expansion, evaluating the efficacy and safety of endovascular treatment of acute ischemic stroke have generated concerns about the future of endovascular approach. However, the tremendous evolution that imaging and endovascular treatment modalities have undergone over the past several years has raised doubts about the validity of these trials. In this paper, we review the role of endovascular treatment strategies in acute ischemic stroke and discuss the limitations and shortcomings that prevent generalization of the findings of recent trials. We also provide our experience in endovascular treatment of acute ischemic stroke.

    Before December 2014, the only proven effective treatment for acute ischemic stroke was recombinant tissue-type plasminogen activator (r-tPA). This has now changed with the publication of the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN), Endovascular Treatment for Small Core and Anterior Circulation Proximal Occlusion With Emphasis on Minimizing CT to Recanalization Times (ESCAPE), Extending the Time for Thrombolysis in Emergency Neurological Deficits--Intra-Arterial (EXTEND IA), Solitaire With the Intention for Thrombectomy as Primary Endovascular Treatment Trial (SWIFT PRIME), and Randomized Trial of Revascularization With the Solitaire FR Device Versus Best Medical Therapy in the Treatment of Acute Stroke Due to Anterior Circulation Large Vessel Occlusion Presenting Within Eight Hours of Symptom Onset (REVASCAT) studies. We review the main results of these studies and how they inform stroke patient management going forward. The main take home points for neurologists are (1) intra-arterial thrombectomy is a potently effective treatment and should be offered to patients who have documented occlusion in the distal internal carotid or the proximal middle cerebral artery, have a relatively normal noncontrast head computed tomographic scan, severe neurological deficit, and can have intra-arterial thrombectomy within 6 hours of last seen normal; (2) benefits are clear in patients receiving r-tPA before intra-arterial thrombectomy; r-tPA should not be withheld if the patient meets criteria, and benefit in patients who do not receive r-tPA or have r-tPA exclusions requires further study; and (3) these favorable results occur when intra-arterial thrombectomy is performed in an endovascular stroke center by a coordinated multidisciplinary team that extends from the prehospital stage to the endovascular suite, minimizes time to recanalization, uses stent-retriever devices, and avoids general

    In patients who are not responsive to intravenous tissue plasminogen activator (IV t-PA), the present study aimed to report recanalization rates, the incidence of hemorrhagic transformation (HT), and clinical outcomes of additional endovascular therapy (AET), and to investigate the usefulness of magnetic resonance angiography-diffusion mismatch (MDM) in a selection of patients eligible for AET. Fifty-eight patients who received IV t-PA therapy because of intracranial major artery occlusion between April 2007 and November 2010 were divided into 2 groups: 18 patients in the AET group and 21 patients in the IV t-PA nonresponders group. The remaining 19 patients were responders to IV t-PA and therefore not eligible for this study. Recanalization rates, HT incidence, and 3-month outcomes were assessed, and the relationship between MDM and clinical outcome was examined. A 3-month modified Rankin Scale (mRS) score of 0 to 3 was seen more frequently in the AET group (72% in the AET group v 29% in the nonresponder group; P = .01). Serious outcomes (3-month mRS of 5-6) were seen significantly less often in the AET group (17%) than in the nonresponder group (57%; P = .019). There were no differences in the incidence of HT. In the AET group, reappraisal considering MDM revealed a significantly higher rate of a 3-month mRS of 0 to 3 in the MDM-positive group compared to the MDM-negative group (86% v 25%, respectively; P = .044). Serious outcomes were observed significantly less frequently in the MDM-positive group compared to the MDM-negative group (0% v 75%, respectively; P = .005). AET for nonresponders to IV t-PA was safe, improved recanalization rates, and led to better prognoses. MDM was a very good predictor of improved prognosis in a selection of eligible patients for AET after IV t-PA. Copyright © 2013 National Stroke Association. Published by Elsevier Inc.

    Purpose: To report about the endovascular treatment of isolated iliac artery aneurysms (IIAA) with stentgraft placement and transluminal or CT-guided embolization of the internal iliac artery or the combination of these methods. Methods and materials: Over a period of 5.6 years, 36 interventions were performed in 20 patients with 23 IIAAs. In a retrospective analysis patient records were reviewed. The CT-angiography follow-up was evaluated for the presence of re-perfusion of the IIAA and for change of aneurysm diameter. Results: Primary success was achieved in 15/23 aneurysms (65%), and secondary success in 21/23 aneurysms (91%). In 5/23 cases two interventions and in 1/23 cases three interventions were necessary to achieve secondary success. Embolization alone, as a therapy for aneurysms involving only the internal iliac artery, had a success rate of 27%. No procedure-related minor or major complications occurred. Mean decrease of aneurysm size during a mean observation period of 14.1 months was 6.9% which was not significant (p = 0.3; 95% confidence interval +7-21%). Conclusion: Endovascular therapy of isolated iliac artery aneurysms performed percutaneously has become a treatment alternative to open surgical repair. This method is feasible and safe with low procedure-related morbidity and mortality. However, on average more than one intervention has to be performed to achieve successful permanent exclusion of the aneurysm and embolization alone in isolated internal iliac artery aneurysms is not sufficient

    Prospective study to evaluate clinical results and complications of endovascular abdominal aortic aneurysm treatment in a mid-term follow-up. Materials and methods: A total of 122 patients (9 females, 113 males, average age 70.0{+-}7,9 years) with abdominal aortic aneurysms were treated with stent grafts (53 Vanguard or Stentor endografts, 69 Talent endografts). Group I consisted of 40 patients who had all aortic tributaries of the aneurysm sac occluded prior to endovalscular grafting, either spontaneously by parietal thrombosis or by selective coil embolization of the respective ostia preserving collateral circulation distal to the vessel occlusion. Group II consisted of 82 patients and included all cases without or with incomplete coil embolization with at least one patent vessel. Stent grafting was performed in general anesthesia in the first 21 patients, followed by peridural anesthesia in 15 cases, and local anesthesia with conscious sedation in 86 cases. The results were evaluated with Spiral-CT, MRI and radiographs of the endovascular graft, with follow-up examinations obtained at 3, 6, 12 months, and every year - Implantation was successfully completed in all cases without primary conversion surgery, laparotomy or any significant complication. Mean follow-up was 29{+-}21 months (maximum 82 months). The 30-day mortality was 0,8% due to a myocardial infarction 3 days after discharge from the hospital. A total of 47 re-interventions were performed in 29 patients (23.8%), with 35 re-interventions in 18 cases with Vanguard or Stentor endografts and 12 re-interventions in 11 patients with Talent endografts. 23 percutaneous re-interventions included distal graft extension (n=11), Wallstent for kinking and limb stenosis (n=3), and secondary coil embolization of collateral vessels (n=9). 24 surgical re-interventions included proximal graft extension (n=6), new endovascular grafts (n=3), surgical clipping of lumbar and mesenteric artery branches for type-II endoleaks

    Prophylactic placement of endovascular balloon occlusion catheters has grown to be part of the surgical plans to control intraoperative hemorrhage in cases of abnormal placentation. We performed a systematic literature review to investigate the safety and effectiveness of the use of REBOA during cesarean delivery in pregnant woman with morbidly adherent placenta. A systematic review was performed. Relevant case reports and nonrandomized studies were identified by the literature search in MEDLINE. We included studies involving pregnant woman with diagnosis of abnormal placentation who underwent cesarean delivery with REBOA placed for hemorrhage control. MINORS' criteria were used to evaluate the risk of bias of included studies. A formal meta-analysis was not performed. Eight studies were included in cumulative results. These studies included a total of 392 patients. Overall, REBOA was deployed in 336 patients. Six studies reported the use of REBOA as an adjunct for prophylactic hemorrhage control in pregnant woman with diagnosis of morbidly adherent placenta undergoing elective cesarean delivery. In two studies, REBOA was deployed in patients already in established hemorrhagic shock at the moment of cesarean delivery. REBOA was deployed primarily by interventional radiologists; however, one study reported a surgeon as the REBOA provider. The results from our qualitative synthesis indicate that the use of REBOA during cesarean delivery resulted in less blood loss with a low rate complications occurrence. REBOA is a feasible, safe, and effective means of prophylactic and remedial hemorrhage control in pregnant women with abnormal placentation undergoing cesarean delivery.

    Acceptable limb salvage rates underlie the widespread use of endovascular therapy (EVT) for patients with critical limb ischemia (CLI) secondary to isolated infrapopliteal lesions; however, post-EVT delayed wound healing remains a challenge. Predictors of delayed wound healing and their use in risk stratification of EVT in patients with CLI due to isolated infrapopliteal lesions are explored. This was a retrospective multicenter study. 871 consecutive critically ischemic limbs were studied. There was tissue loss in 734 patients (age: 71 ± 10 years old; 71% male) who had undergone EVT between April 2004 and December 2012. The wound healing rate after EVT was estimated by the Kaplan-Meier method. The association between baseline characteristics and delayed wound healing was assessed by the Cox proportional hazard model. Diabetes mellitus and regular dialysis were present in 75% (553/734) and 64% (476/734) of patients, respectively; 67% of limbs (585/871) had Rutherford class 5 CLI; 8% (67/871) of wounds were located in the heel only; 25% (219/871) of limbs had Rutherford 6 (involving not only the heel); and 42% (354/871) of wounds were complicated by infection. The rate of freedom from major amputation at 1 year reached 88%, whereas the wound healing rate was 67%. Median time to wound healing was 146 days. By multivariate analysis, non-ambulatory status (hazard ratio [HR], 1.58; 95% confidence interval [CI] 1.31-1.91) serum albumin wound infection (HR 1.24; 95% CI 1.03-1.50), EVT not based on angiosome concept (HR 1.28; 95% CI 1.06-1.55), and below the ankle (BTA) 0 vessel runoff after EVT (HR 1.45; 95% CI 1.14-1.86) were independent predictors of delayed wound healing. Non-ambulatory status, low albumin level, Rutherford 6 (not only heel), wound infection, indirect intervention, and poor BTA runoff were independent predictors for delayed wound healing after EVT in patients with CLI secondary to infrapopliteal lesions, and their use in risk stratification allows

    2006-01-01

    For over 50 years, electron beams have been an important modality for providing an accurate dose of radiation to superficial cancers and disease and for limiting the dose to underlying normal tissues and structures. This review looks at many of the important contributions of physics and dosimetry to the development and utilization of electron beam therapy, including electron treatment machines, dose specification and calibration, dose measurement, electron transport calculations, treatment and treatment-planning tools, and clinical utilization, including special procedures. Also, future changes in the practice of electron therapy resulting from challenges to its utilization and from potential future technology are discussed. (review)

  5. Radiological protection issues in endovascular use of radiation sources

    International Nuclear Information System (INIS)

    2006-02-01

    The use of radiation from radioactive materials for cancer treatment is well established. However, examples of uses of radiation therapy for benign conditions have been limited. Placing a radioactive source in the blood vessel so as to irradiate the surrounding inner periphery of the vessel has been attempted in recent years to prevent restenosis after percutaneous coronary and peripheral interventions. This kind of endovascular application provides treatment options that are less invasive for various vascular conditions compared with open surgery. As a part of the International Atomic Energy Agency's (IAEA) function for providing for application of the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS) that were jointly sponsored by the IAEA, FAO, ILO, OECD/NEA, PAHO and WHO, the IAEA planned a coordinated research project (CRP) that was to start in 2002 on radiological protection problems in endovascular use of radiation sources. However, as experts soon realized that the interest in this modality was waning, the CRP was not initiated. Nevertheless, it was felt that it would be appropriate to compile the information available on radiological protection problems observed so far and their possible solutions. This work was seen as part of a broader IAEA programme that covered accident prevention in radiotherapy. Publications on this topic have included, inter alia, Lessons Learned from Accidental Exposures in Radiotherapy (Safety Reports Series No. 17); Accidental Overexposure of Radiotherapy Patients in Bialystok; Investigation of an Accidental Exposure of Radiotherapy Patients in Panama; Accidental Overexposure of Radiotherapy Patients in San Jose, Costa Rica; and Investigation of an Accidental Exposure of Radiotherapy Patients in Poland. Keeping in mind that endovascular applications involve specialists such as cardiologists, angiologists and surgeons, all of whom might not have a

    To demonstrate the effectiveness of endovascular treatment (EVT) with self-expandable bare stents for malignant superior vena cava syndrome (SVCS) and to analyze predictive factors of EVT efficacy. Retrospective review of the 164 patients with malignant SVCS treated with EVT in our hospital from August 1992 to December 2007 and followed until February 2009. Endovascular treatment includes angioplasty before and after stent placement. We used self-expandable bare stents. We studied results of this treatment and looked for predictive factors of clinical efficacy, recurrence, and complications by statistical analysis. Endovascular treatment was clinically successful in 95% of cases, with an acceptable rate of early mortality (2.4%). Thrombosis of the superior vena cava was the only independent factor for EVT failure. The use of stents over 16 mm in diameter was a predictive factor for complications (P = 0.008). Twenty-one complications (12.8%) occurred during the follow-up period. Relapse occurred in 36 patients (21.9%), with effective restenting in 75% of cases. Recurrence of SVCS was significantly increased in cases of occlusion (P = 0.01), initial associated thrombosis (P = 0.006), or use of steel stents (P = 0.004). Long-term anticoagulant therapy did not influence the risk of recurrence or complications. In malignancy, EVT with self-expandable bare stents is an effective SVCS therapy. These results prompt us to propose treatment with stents earlier in the clinical course of patients with SVCS and to avoid dilatation greater than 16 mm.

    Advanced endovascular aortic repair can be used to treat patients with extensive and complex aortic disease who are at risk of spinal cord ischaemia. The aim of this study was to compare whether life satisfaction differs between patients with and without spinal cord ischaemia at mid-term follow-up. Nested case-control study. Among patients undergoing advanced endovascular aortic repair between 2009 and 2012, 18 patients with spinal cord ischaemia and 33 without were interviewed at home. The Life Satisfaction Questionnaire (LiSat-11) and the Satisfaction With Life Scale (SWLS) were used. LiSat-11 found that patients with spinal cord ischaemia were more dissatisfied with their activities of daily living than were patients without spinal cord ischaemia (p=0.012). Both groups had similar, very low, scores in the sexual life domain; median 2.0 (interquartile range (IQR) 1.5-3.0) and 3.0 (IQR 2.0-4.0), respectively. There was no difference in SWLS between the groups. This study cohort of patients who underwent advanced endovascular aortic repair was rather homo-genous in their rating of life satisfaction and there was little difference between mid-term survivors who had spinal cord ischaemia and those who did not.

    Background Anterior inferior cerebellar artery (AICA) aneurysms are rare and published clinical experience with these aneurysms is limited. Objective The objective of this article is to report angiographic characteristics and results associated with premeatal, meatal and postmeatal segments, surgical and endovascular therapies. Methods A literature review was performed through PubMed using “anterior inferior cerebellar artery aneurysm” through January 2016. Clinical data, angiograms, management techniques, and patient outcomes were reviewed for 47 collected cases in 30 previous reports. Results Of these aneurysms, 21 (44.7%) were associated with meatal segment, 10 (21.3%) were postmeatal and 16 (34.0%) were premeatal. Patients with meatal aneurysms are more likely to present with subarachnoid hemorrhage and hearing loss and facial palsy (77.8%). Patient outcomes of meatal aneurysms presented with more neuropathies (51.7%) and cerebellar symptoms (14.3%) (p = 0.049). Four cases of meatal aneurysm with preoperative cranial nerve deficits (two VII and two VIII) showed improvement after surgery. Endovascular treatment achieved outcomes similar to surgical treatment (p = 0.327). Conclusions AICA aneurysms have a predilection for meatal segment. Patients with meatal aneurysms are more likely to present with subarachnoid hemorrhage and hearing loss and facial palsy. Patient outcomes of meatal aneurysms presented with more neuropathies and cerebellar symptoms. Endovascular treatment achieved outcomes similar to surgical treatment. PMID:27485045

    Durante, Marco; Paganetti, Harald

    2016-09-01

    Charged particle therapy has been largely driven and influenced by nuclear physics. The increase in energy deposition density along the ion path in the body allows reducing the dose to normal tissues during radiotherapy compared to photons. Clinical results of particle therapy support the physical rationale for this treatment, but the method remains controversial because of the high cost and of the lack of comparative clinical trials proving the benefit compared to x-rays. Research in applied nuclear physics, including nuclear interactions, dosimetry, image guidance, range verification, novel accelerators and beam delivery technologies, can significantly improve the clinical outcome in particle therapy. Measurements of fragmentation cross-sections, including those for the production of positron-emitting fragments, and attenuation curves are needed for tuning Monte Carlo codes, whose use in clinical environments is rapidly increasing thanks to fast calculation methods. Existing cross sections and codes are indeed not very accurate in the energy and target regions of interest for particle therapy. These measurements are especially urgent for new ions to be used in therapy, such as helium. Furthermore, nuclear physics hardware developments are frequently finding applications in ion therapy due to similar requirements concerning sensors and real-time data processing. In this review we will briefly describe the physics bases, and concentrate on the open issues.

  17. Endovascular Radiofrequency Ablation for Varicose Veins

    Science.gov (United States)

    2011-01-01

    Executive Summary Objective The objective of the MAS evidence review was to conduct a systematic review of the available evidence on the safety, effectiveness, durability and cost–effectiveness of endovascular radiofrequency ablation (RFA) for the treatment of primary symptomatic varicose veins. Background The Ontario Health Technology Advisory Committee (OHTAC) met on August 26th, 2010 to review the safety, effectiveness, durability, and cost-effectiveness of RFA for the treatment of primary symptomatic varicose veins based on an evidence-based review by the Medical Advisory Secretariat (MAS). Clinical Condition Varicose veins (VV) are tortuous, twisted, or elongated veins. This can be due to existing (inherited) valve dysfunction or decreased vein elasticity (primary venous reflux) or valve damage from prior thrombotic events (secondary venous reflux). The end result is pooling of blood in the veins, increased venous pressure and subsequent vein enlargement. As a result of high venous pressure, branch vessels balloon out leading to varicosities (varicose veins). Symptoms typically affect the lower extremities and include (but are not limited to): aching, swelling, throbbing, night cramps, restless legs, leg fatigue, itching and burning. Left untreated, venous reflux tends to be progressive, often leading to chronic venous insufficiency (CVI). A number of complications are associated with untreated venous reflux: including superficial thrombophlebitis as well as variceal rupture and haemorrhage. CVI often results in chronic skin changes referred to as stasis dermatitis. Stasis dermatitis is comprised of a spectrum of cutaneous abnormalities including edema, hyperpigmentation, eczema, lipodermatosclerosis and stasis ulceration. Ulceration represents the disease end point for severe CVI. CVI is associated with a reduced quality of life particularly in relation to pain, physical function and mobility. In severe cases, VV with ulcers, QOL has been rated to be as bad

    The most prevalent lesion of the vertebral artery is an atheromatous plaque located at its origin from the subclavian artery. A case of successful management of a symptomatic vertebral artery aneurysm due to Ehlers-Danlos syndrome is reported. The patient had asymptomatic posterior intracerebral artery dissection on the contralateral side. A common carotid artery to V-3 segment bypass using reversed saphenous vein graft was carried out. Avulsion of the V-2 segment occurred peroperatively and endovascular coil embolization of the vertebral artery aneurysm was performed. Endovascular equipment and training must be in the armamentarium of vascular surgeons as more complex cases are being treated, which demands new approaches for ultimate clinical success. This unique case outlines what might unexpectedly occur. Endovascular intervention as an adjuvant procedure provides a satisfactory outcome in what could have been a catastrophe.

  19. Clinical impact of chronic renal insufficiency on endovascular aneurysm repair.

    Park, Brian; Mavanur, Arun; Drezner, A David; Gallagher, James; Menzoian, James O

    Endovascular aneurysm repair of abdominal aortic aneurysms has become a viable alternative to open repair. A significant proportion of this patient population has chronic renal insufficiency. The surgical outcomes associated with endovascular repair in 342 patients, with and without chronic renal insufficiency, are reported. Perioperative mortality, length of admission, length of intensive care unit admission, and rates of acute renal failure, congestive heart failure, myocardial infarction, conversion to open surgery, progression to hemodialysis, and incidence of endoleaks were retrospectively reviewed and analyzed. Endovascular repair demonstrated higher rates of acute renal failure, longer length of stay, and longer intensive care unit admissions in patients with chronic renal insufficiency. Patients with severe renal dysfunction demonstrated markedly elevated mortality and morbidity. These results indicate that chronic renal insufficiency is not an absolute contraindication to endovascular repair in patients with moderate renal dysfunction, but patients with severe renal dysfunction perform poorly after aortic reconstruction.

    Full Text Available Objective : To review the trend of the study related to Leech therapy and to establish the hereafter direction for the study on Leech therapy. Methods : I reviewed and analyzed all the theses published in Domestic and Foreign research institution from 1990 to 2009. Results : The following results were obtained in this study. 1. Analyzed number of theses published, there was no significance per year. 2. Classified by theme of journal, journals related to surgery were most(41 journals, 75.92% among 54 kinds. 3. Classified by theses by research method and thesis types, case report accounted for nearly twothirds (52 pieces, 68.42% of all theses and consideration of document was next(9 pieces, 11.84%. 4. With the most case of venous congestion after plastic and reconstructive surgery(33 pieces, 63.46%, leech therapy was effective on illnesses such as haematoma, macroglossia, purpura, varicous vein, avulsion injury, neurovascular compression, diabetic neuropathy, penoscrotal oedema, buerger's disease, rheumatoid arthritis. 5. Two most appeared adverse effects were anemia and infection. Immediate blood transfusion was done for recovering anemia and prophylactic 3rd generation antibiotics to infection were emphasized in more than half of case reports. 6. All of consideration of documents was retrospective study of cases related leech therapy and 3 pieces of them emphasized prophyratic antibiotic treatment for preventing infection. 7. The study of clinical trail type started first in 2002 and osteoarthritis of knee and carpometacarpal joint were main target. As see above result, Leech therapy was effective cure and could be used in disease induced by venous congestion. And I think that it is necessary to perform additional study related to solution of problems about leech therapy and protocol for using in clinical practice.

    Precisely defining complications, which are used to measure overall quality, is necessary for critical review of delivery of care and quality improvement in endovascular neurosurgery, which lacks common definitions for complications. Furthermore, in endovascular interventions, events that may be labeled complications may not always negatively affect outcome. Our objective is to provide precise definitions for quality evaluation within endovascular neurosurgery. Thus, we propose an endovascular-specific classification system of complications based on our own patient series. This single-center review included all patients who had endovascular interventions from September 2013 to August 2015. Complication types were analyzed, and a descriptive analysis was undertaken to calculate the incidence of complications overall and in each category. Two hundred and seventy-five endovascular interventions were performed in 245 patients (65% female; mean age, 55 years). Forty complications occurred in 39 patients (15%), most commonly during treatment of intracranial aneurysms (24/40). Mechanical complications (eg, device deployment, catheter, or closure device failure) occurred in 8/40, technical complications (eg, failure to deploy flow diverter, unintended embolization, air emboli, retroperitoneal hemorrhage, dissection) in 11/40, judgment errors (eg, patient or equipment selection) in 9/40, and critical events (eg, groin hematoma, hemorrhagic or thromboembolic complications) in 12/40 patients. Only 12/40 complications (30%) resulted in new neurologic deficits, vessel injury requiring surgery, or blood transfusion. We propose an endovascular-specific classification system of complications with 4 categories: mechanical, technical, judgment errors, and critical events. This system provides a framework for future studies and quality control in endovascular neurosurgery. Copyright © 2016 Elsevier Inc. All rights reserved.

    2013-05-01

    The purpose of this review was to summarize recent developments regarding photodynamic therapy (PDT) in the field of dentistry. A review of pertinent literature was carried out in PubMED to determine the current position of PDT applications in dentistry. One hundred thirteen relevant articles were retrieved from PubMED by inserting the keywords "photodynamic therapy", "dentistry", "periodontology", "oral surgery", and "endodontics". It is anticipated that this overview will create a specific picture in the practitioner's mind regarding the current status and use of PDT. In spite of different results and suggestions brought about by different researchers, PDT can be considered as a promising and less invasive technique in dentistry. PDT seems to be an effective tool in the treatment of localized and superficial infections. Within the limitations of the present review, it can be concluded that although PDT cannot replace antimicrobial therapy at its current stage, it may be used as an adjunctive tool for facilitating the treatment of oral infections. Oral infections (such as mucosal and endodontic infections, periodontal diseases, caries, and peri-implantitis) are among the specific targets where PDT can be applied. Further long-term clinical studies are necessary in establishing a more specific place of the technique in the field of dentistry.

    We describe intra-operative and post-discharge outcomes of a case series after the prophylactic use of resuscitative endovascular occlusion of the aorta (REBOA) during elective cesarean delivery in pregnant women with MAP. We furthermore performed a systematic review and meta-analysis to investigate the safety and effectiveness of the use of REBOA during elective cesarean delivery in pregnant women with MAP. Descriptive case series of REBOA (December 2015 to June 2017) used during elective cesarean delivery in pregnant women with MAP. The systematic review was conducted following PRISMA guidelines. We included studies involving pregnant women with a diagnosis of MAP who underwent an elective cesarean delivery with prophylactic REBOA placement. A meta-analysis was performed to assess the overall amount of transfusions and intra-operative hemorrhage of REBOA compared to NO-REBOA cases. A total of 12 patients with MAP underwent elective cesarean delivery with REBOA deployment. The median (IQR) of Packed Red Blood Cells transfused during the first 24 hours following surgery was two units (0-3.5). The median (IQR) of intra-operative blood loss was 1500ml (900-2750). At 28 days all patients were alive, and no adverse outcomes were observed. Four articles were included in the systematic review and meta-analysis. These articles included a total of 441 patients. Quantitative synthesis (meta analysis) found that the use of REBOA as prophylaxis for the prevention of major hemorrhage was associated with a lower amount of intra-operative hemorrhage (in milliliters) (WMD: -1384.66; 95% CI -2141.74, -627.58) and lower requirements of blood products transfusions (in units) (WMD: -2.42; 95% CI -3.90, -0.94). We provide clinical data supporting the use of REBOA in the management of pregnant women with MAP undergoing elective cesarean delivery. Our findings demonstrate the feasibility of REBOA as a prophylactic intervention to improve outcomes in women at risk of catastrophic post

    Purpose: Angioplasty effectively relieves coronary artery stenosis but is often followed by restenosis. Endovascular radiation (β or γ) at the time of angioplasty prevents restenosis in a large proportion of vessels in swine (short term) and humans (short and long term). Little information is available about the effects of this radiation exposure beyond the wall of the coronary arteries. Methods and Materials: Samples were obtained from 76 minipigs in the course of several experiments designed to evaluate endovascular brachytherapy: 76 of 114 coronary arteries and 6 of 12 iliac arteries were exposed to endovascular radiation from 32 P sources (35 Gy at 0.5 mm from the intima). Two-thirds of the vessels had angioplasty or stenting. The vessels were systematically examined either at 28 days or at 6 months after radiation. Results: We found an unexpected lesion: acute necrotizing vasculitis in arterioles located ≤2.05 mm from the target artery. It was characterized by fibrinoid necrosis of the wall, often associated with lymphocytic exudates or thrombosis. Based on the review of perpendicular sections of tissue samples, the arterioles had received between 6 and 40 Gy. This arteriolar vasculitis occurred at 28 days in samples from 51% of irradiated coronary arteries and 100% of irradiated iliac arteries. By 6 months, the incidence of acute vasculitis decreased to 24% around the coronary arteries. However, at that time, healing vasculitis was evident, often with luminal narrowing, in 46% of samples. Vasculitis was not seen in any of 44 samples from unirradiated vessels (0%) and had no relation to angioplasty, stenting, or their sequelae. This radiation-associated vasculitis in the swine resembles the localized lymphocytic vasculitis that we have reported in tissues of humans exposed to external radiation. On the other hand, it is quite different from the various types of systemic vasculitis that occur in nonirradiated humans. Conclusion: Endoarterial brachytherapy

    Full Text Available Cerebral aneurysms are associated with a 50% mortality rate after rupture and patients can suffer significant morbidity during subsequent treatment. Neurosurgical management of both ruptured and unruptured aneurysms has evolved over the years. The historical practice of using microsurgical clipping to treat aneurysms has benefitted in the last two decades from tremendous improvement in endovascular technology. Microsurgery and endovascular therapies are often viewed as competing treatments but it is important to recognize their individual limitations. Some aneurysms are considered complex, due to several factors such as aneurysm anatomy and a patient’s clinical condition. A complex aneurysm often cannot be completely excluded with a single approach and its successful treatment requires a combination of microsurgical and endovascular techniques. Planning such an approach relies on understanding aneurysm anatomy and thus should routinely include 3D angiographic imaging. In patients with ruptured aneurysms, endovascular coiling is a well-tolerated early treatment and residual aneurysms can be treated with intervals of definitive clipping. Microsurgical clipping also can be used to reconstruct the neck of a complex aneurysm, allowing successful placement of coils across a narrow neck. Endovascular techniques are assisted by balloons, which can be used in coiling and testing parent vessel occlusion before sacrifice. In some cases microsurgical bypasses can provide alternate flow for planned vessel sacrifice. We present current paradigms for combining endovascular and microsurgical approaches to treat complex aneurysms and share our experience in 67 such cases. A dual microsurgical–endovascular approach addresses the challenge of intracranial aneurysms. This combination can be performed safely and produces excellent rates of aneurysm obliteration. Hybrid angiographic operating-room suites can foster seamless and efficient complementary application

    The aim of this study was to report our experience in endovascular treatment of total aortoiliac occlusion. Five patients who underwent endovascular recanalization procedures including manual aspiration thrombectomy, balloon angioplasty, and stent placement for total aortoiliac occlusion in a 4-year period were reviewed retrospectively. The mean age of patients was 51 years (range, 43 to 58 years). All patients had abdominal aorta and bilateral common iliac artery occlusion with or without external iliac artery occlusion. All patients either had a contraindication to surgery or refused it. Initial technical success was obtained in four of five (80%) patients. Endovascular techniques were successful in four patients who had good distal runoff and short-segment aortoiliac occlusion, but failed in a patient who had the worst distal runoff and long-segment aortoiliac occlusion. We observed two major complications, one of which was bilateral rupture of the common iliac arteries treated with covered stent placement. Another patient had extension of intra-aortic thrombus into the iliac stent after primary stenting. This was successfully treated with manual aspiration thrombectomy. Aortic and iliac stents remained patent during the follow-up period (median, 18 months; range, 3 to 26 months) in four patients. Primary patency rates at 6, 12, and 24 months were all 80%. In conclusion, endovascular treatment can be an alternative for aortoiliac occlusion in selected patients. Short- to midterm follow-up so far is satisfactory. Removal of intra-aortic thrombus with manual aspiration thrombectomy before balloon angioplasty and/or stenting is possible and a good alternative to thrombolysis.

    Summary Aneurysms of the A1 segment of the anterior cerebral artery (A1A) are rare and challenging to treat. Less information is available regarding their management by endovascular approach. We evaluated our experience of endovascular treatment in 15 patients with unruptured A1As. We retrospectively reviewed unruptured A1As treated by embolization at our hospital. The clinical data and angiographic results were reviewed. A special technique involving shaping microcatheter tips was used for catheterization. From September 2009 to December 2012, 15 patients presenting with unruptured A1As were identified. All the patients were treated by selective embolization including five patients with balloon-assisted coiling (BAC) or stent-assisted coiling (SAC). These adjunctive techniques were used to catheterize the sac safely or to protect a branch at the neck. According to the location and direction of the aneurysm, “Z-shaped”, “S-Shaped” or “U-Shaped” microcatheter tip shaping was used for microcatheter positioning and stabilization. All patients showed an excellent clinical outcome. A complete aneurysm occlusion was obtained in all the patients. Endovascular treatment of A1As is feasible and associated with good results. Because of their location and close relationship with perforators, endovascular treatment of A1As sometimes requires the use of BAC or SAC. The microcatheter tip shaping technique is very important for coiling. Our results suggest that endovascular treatment is a suitable therapeutic option for unruptured A1As when the aneurysm size is optimal for embolization. PMID:23693042

    The safety and efficacy of endovascular therapies for ascending aortic pseudoaneurysms (AAPs) are still controversial. We report an endovascular correction of an AAP in a high-risk surgical patient and present the results of a literature review focusing on AAP treatment strategies. A multilingual search of AAP therapy was performed with limiting dates of January 1980 to May 2014. The studies were classified by intervention. A 79-year-old male with a 9 × 10 × 7 cm AAP in the anterior mediastinum was considered too high risk for surgery. An endovascular closure with a 12 mm Amplatzer septal occluder device (St. Jude Medical) was performed, and computed tomography angiography at 3-month follow-up exhibited a thrombosed AAP with minimal residual shunt. In our literature search, we identified 355 cases of AAPs, mostly case reports (91.5%) and a few patient series (8.5%). Surgical correction accounted for 73.8% of the cases, 5% of the patients were conservatively treated or considered too critically ill for any intervention, and 21.2% were treated with endovascular techniques. The most commonly reported endovascular techniques were stent grafts (9.8%) and septal occluder devices (9.8%). Although endovascular closure of AAPs with off-label devices is a reliable option for controlling the expansion and symptoms in high-risk surgical patients, solid data on survival are lacking. Efforts to promote discussion within the heart team to expand the application of endovascular techniques can provide groundbreaking evidence to support the use of endovascular techniques as guideline therapy when facing these complicated cases.

    Concave shape with variable size target volume makes treatment planning for the breast/chest wall a challenge. Conventional techniques used for the breast/chest wall cancer treatment provided better sparing of organs at risk (OARs), with poor conformity and uniformity to the target volume. Advanced technologies such as intensity modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) improve the target coverage at the cost of higher low dose volumes to OARs. Novel hybrid techniques present promising results in breast/chest wall irradiation in terms of target coverage as well as OARs sparing. Several published data compared these technologies for the benefit of the breast/chest wall with or without nodal volumes. The aim of this article is to review relevant data and identify the scope for further research in developing optimal treatment plan for breast/chest wall cancer treatment.

    To modify, content validate, and evaluate a teamwork assessment tool for use in endovascular surgery. A multistage, multimethod study was conducted. Stage 1 included expert review and modification of the existing Observational Teamwork Assessment for Surgery (OTAS) tool. Stage 2 included identification of additional exemplar behaviours contributing to effective teamwork and enhanced patient safety in endovascular surgery (using real-time observation, focus groups, and semistructured interviews of multidisciplinary teams). Stage 3 included content validation of exemplar behaviours using expert consensus according to established psychometric recommendations and evaluation of structure, content, feasibility, and usability of the Endovascular Observational Teamwork Assessment Tool (Endo-OTAS) by an expert multidisciplinary panel. Stage 4 included final team expert review of exemplars. OTAS core team behaviours were maintained (communication, coordination, cooperation, leadership team monitoring). Of the 114 OTAS behavioural exemplars, 19 were modified, four removed, and 39 additional endovascular-specific behaviours identified. Content validation of these 153 exemplar behaviours showed that 113/153 (73.9%) reached the predetermined Item-Content Validity Index rating for teamwork and/or patient safety. After expert team review, 140/153 (91.5%) exemplars were deemed to warrant inclusion in the tool. More than 90% of the expert panel agreed that Endo-OTAS is an appropriate teamwork assessment tool with observable behaviours. Some concerns were noted about the time required to conduct observations and provide performance feedback. Endo-OTAS is a novel teamwork assessment tool, with evidence for content validity and relevance to endovascular teams. Endo-OTAS enables systematic objective assessment of the quality of team performance during endovascular procedures. Copyright © 2016. Published by Elsevier Ltd.

    The purpose is to review the results and impact of recent positive studies on endovascular stroke treatment in the context of previous negative trials. Since October 2014, the results of five randomized controlled multicenter trials on the endovascular stroke treatment as adjunct to conservative treatment (largely including intravenous tissue-type plasminogen activator) versus conservative treatment alone have been published. All of these trials largely used stent retrievers as endovascular device and included patients with proven large vessel occlusion (mostly distal internal carotid or proximal middle cerebral artery (M1), short time windows after stroke onset and mostly small infarctions on initial imaging. Over all there was an overwhelming beneficial effect on outcome measured as shift in the modified Rankin Scale score and independent survival, respectively. Moreover, the rate of adverse events, in particular hemorrhage rate, was not increased. These new findings contrast previous studies on endovascular stroke treatment using mostly first generation nonstent retriever devices, longer time windows and different imaging inclusion criteria, which were overall neutral for patient outcome. Endovascular stroke treatment with stent retrievers is the standard of care in large vessel occlusion. New randomized controlled trials should investigate safety and efficacy in extended indications as advanced time windows or more extensive signs of ischemia on initial imaging. The same applies for new devices apart from stent retrievers.

    To illustrate complex interdisciplinary decision making and the utility of modern endovascular techniques in the management of patients with carotid blowout syndrome (CBS). Retrospective chart review. Patients treated with endovascular strategies and/or surgical modalities were included. Control of hemorrhage, neurological, and survival outcomes were studied. Between 2004 and 2014, 33 patients had 38 hemorrhagic events related to head and neck cancer that were managed with endovascular means. Of these, 23 were localized to the external carotid artery (ECA) branches and five localized to the ECA main trunk; nine were related to the common carotid artery (CCA) or internal carotid artery (ICA), and one event was related to the innominate artery. Seven events related to the CCA/ICA or innominate artery were managed with endovascular sacrifice, whereas three cases were managed with a flow-preserving approach (covered stent). Only one patient developed permanent hemiparesis. In two of the three cases where the flow-preserving approach was used, the covered stent eventually became exposed via the overlying soft tissue defect, and definitive management using carotid revascularization or resection was employed to prevent further hemorrhage. In cases of soft tissue necrosis, vascularized tissues were used to cover the great vessels as applicable. The use of modern endovascular approaches for management of acute CBS yields optimal results and should be employed in a coordinated manner by the head and neck surgeon and the neurointerventionalist. 4.

    This study was performed to compare endovascular repair with conventional open repair of isolated iliac artery aneurysms (IAAs). We retrospectively reviewed the charts of all patients who underwent repair of isolated IAAs between January 2008 and June 2012. Patients with infected, mycotic and ruptured iliac aneurysms and those with concurrent infrarenal abdominal aortic aneurysms greater than 30 mm in diameter were excluded from this analysis. A total of 32 patients were treated with isolated IAAs. There were 20 open and 12 endovascular repairs. A comparison of the length of the operation (238 ± 84 min in the open group vs 176 ± 72 min in the endovascular group, P = 0.03) and intraoperative blood loss (1,735 ± 1,177 ml in the open group vs 503 ± 711 ml in the endovascular group, P = 0.01), revealed significant differences in favor of the endovascular procedure. Postoperative complications were less common in the endovascular group, although the difference did not reach statistical significance. The management of isolated IAAs with both endovascular and open repair can be accomplished with very low morbidity rates. Therefore, endovascular repair can be considered an alternative treatment for isolated IAAs.

    Critical limb ischemia (CLI) represents the most severe clinical manifestation of peripheral arterial disease. In the absence of timely revascularization, CLI carries high risk of mortality and amputation. Over the past decade, endovascular revascularization has rapidly become the preferred primary treatment strategy for CLI, especially for the treatment of below-the-knee disease. Advances in percutaneous devices and techniques have expanded the spectrum of patients with CLI who are deemed candidates for revascularization. This review will focus on advances in endovascular options for the treatment of CLI, in particular for below-the-knee disease.

    S. A. Prozorov

    2016-01-01

    Full Text Available An acute disorder of mesenteric circulation is a serious disease with high mortality. It occurs much more often due to the arterial flow impairment, and less often due to the venous blood flow disturbance. Etiology: thrombosis, embolism, compression of the lumen under dissection. To restore the mesenteric blood flow endovascular techniques are performed: mechanical recanalization, balloon angioplasty, stent installation, thrombolysis, tromboaspiration and their various combinations. If recanalization of the superior mesenteric artery is unable to be performed, hybrid operations are carried out anterogradely: retrograde stent installation during laparotomy. The review shows that endovascular methods is a promising direction of treatment for acute mesenteric ischemia.

    Transient paraplegia of the lower limbs is a rare condition and when has a vascular etiology is usually associated with thromboembolic events, aortic dissection, aortic aneurysms, or as a complication of the surgical correction of those deseases. There is no case reported of acute paraplegia caused by a segmental thrombotic subocclusion of the descending thoracic aorta. We report a not yet described clinical situation of a young patient (51 years) admitted to the emergency care department for treatment of systemic arterial hypertension of difficult control with 4 antihypertensive medication classes. At the intensive care unit for treatment with intravenous antihypertensive, evolved with acute paraplegia and a segmental thrombotic subocclusion of the descending thoracic aorta, previously free of disease, was diagnosed. He was submitted to endovascular treatment with total recovery of the deficits. The previously normal descending thoracic aorta may be a site of segmental thrombosis and may lead to paraplegia. Early endovascular treatment can reverse this type of situation. Copyright © 2018 Elsevier Inc. All rights reserved.

    The tendency of posterior fossa arteriovenous malformations (pfAVM) to develop associated aneurysms (AA) is a well-known phenomenon with an increased total risk of rupture. Most pfAVM and AA develop in the territory of the posterior inferior cerebellar artery while the involvement of the anterior inferior cerebellar artery (AICA) is extremely rare. We describe an unusual case of an arteriovenous malformation (AVM) supplied by the AICA with a "proximal" AA. This unique combination of vascular lesions has been reported in only four cases so far, limiting the available experience that can safely guide the therapeutic intervention. This study describes a 59-year-old female presented with a subarachnoid hemorrhage, Hunt and Hess grade 4. Angiography demonstrated an AVM fed mainly by the right AICA and draining superficially into the transverse sinus (Spetzler-Martin grade II). In addition, there was a ruptured proximal AICA aneurysm. An endovascular approach was chosen to coil the aneurysm and obliterate the AVM using ONYX in a multi-staged process. The patient recovered well without residual deficit at 6-month follow-up. To the best of our knowledge, this is the first report describing a proximal AICA aneurysm and AVM treated by endovascular means. The outcome was very good, considering the technically demanding location. All previously reported cases with exactly similar lesions were managed surgically, with inconclusive outcomes. The data presented in this study are meant to help in decision-making process for similar cases till more data are available.

    A 35-year-old woman presented with an aortobronchial fistula after polyester graft replacement of coarctation of the descending thoracic aortic. Treatment of the fistula included antibiotic therapy and stent graft placement. Life-threatening sepsis developed in the postoperative period. Subsequent treatment required excision of the infected graft complex with extra-anatomic reconstruction of the thoracic aorta. The patient had a very stormy postoperative course and required heroic measures, including mechanical circulatory support, to achieve survival. The present case demonstrates failure of endovascular therapy of an aortobronchial fistula. The case should serve as a cautious reminder that the underlying cause for infection remains even after apparent successful endovascular therapy. Copyright © 2012 The Society of Thoracic Surgeons.

    Purpose: Endovascular radiation has reduced postangioplasty restenosis in preclinical and early clinical studies. External radiation treatment may have advantages over endovascular therapy. We examined vascular and perivascular tissue responses to endovascular and external irradiation in pig coronary arteries. Methods and Materials: Ninety-one animals received endovascular or external radiation following balloon injury and were sacrificed at 14, 30, or 180 days. Injured segments of coronary vessels including perivascular and myocardial tissues were evaluated with histochemistry. Results: Endovascular radiation was associated with delayed arterial wound healing as late as 6 months, evidenced by paucity of smooth muscle α-actin in neointimal cells compared to control. External treatment was associated with increased collagen in neointima and adventitia, and focal interstitial necrosis in adjacent myocardium. Conclusions: These investigations showed whole-heart 14 Gy external radiation treatment following coronary injury exacerbated certain aspects of arterial healing. In addition focal myocardial necrosis and fibrosis was observed following external but not endovascular irradiation. Endovascular radiation has some advantages over external irradiation; however the persistence of a synthetic smooth muscle cell phenotype in the neointima at 6 months suggests ionizing radiation in general may have profound effects on vessel architecture over the long term

    Mechanical thrombectomy has become the standard of care for management of most large vessel occlusion (LVO) strokes. When patients with LVO present with minor stroke symptomatology, no consensus on the role of mechanical thrombectomy exists. A systematic review and meta-analysis were performed to identify studies that focused on mechanical thrombectomy, either as a standalone treatment or with intravenous tissue plasminogen activator (IV tPA), in patients with mild strokes with LVO, defined as a baseline National Institutes of Health Stroke Scale score ≤5 at presentation. Data on methodology, quality criteria, and outcome measures were extracted, and outcomes were compared using odds ratio as a summary statistic. Five studies met the selection criteria and were included. When compared with medical therapy without IV tPA, mechanical thrombectomy and medical therapy with IV tPA were associated with improved 90-day modified Rankin Scale (mRS) score. Among medical patients who were not eligible for IV tPA, those who underwent mechanical thrombectomy were more likely to experience good 90-day mRS than those who were not. There was no significant difference in functional outcome between mechanical thrombectomy and medical therapy with IV tPA, and no treatment subgroup was associated with intracranial hemorrhage or death. In patients with mild strokes due to LVO, mechanical thrombectomy and medical therapy with IV tPA led to better 90-day functional outcome. Mechanical thrombectomy plays an important role in the management of these patients, particularly in those not eligible for IV tPA. Copyright © 2017 Elsevier Inc. All rights reserved.

    2017-07-01

    This paper is a synthesis of the available literature on occupational therapy interventions performed in the adult intensive care unit (ICU). The databases of Ovid MEDLINE, Embase, the Cochrane Library, ClinicalTrials.gov and CINAHL databases were systematically searched from inception through August 2016 for studies of adults who received occupational therapy interventions in the ICU. Of 1,938 citations reviewed, 10 studies met inclusion criteria. Only one study explicitly discussed occupational therapy interventions performed and only one study specifically tested the efficacy of occupational therapy. Future research is needed to clarify the specific interventions and role of occupational therapy in the ICU and the efficacy of these interventions.

    Obesity is a significant public health concern globally. It is associated with poor physical health, mental health and subjective well-being and limitations on occupational participation. With its focus on the relationship between occupation, health and well-being, occupational therapy would appear to be well placed to address both the causes and consequences of obesity. The aim of this review was to explore the scope of the role of occupational therapy practice in this field and the supporting evidence base. Searches were conducted in four online databases and nine occupational therapy journals. Articles were included if they were theoretical, quantitative or qualitative research, explicitly related to occupational therapy and obesity, published in peer-reviewed journals, in English between 2002 and 2012. All research articles were critically reviewed and thematic analysis was conducted across all of the articles in the review. Eight theoretical articles, 12 quantitative and two qualitative research studies were included. Only three were outcome studies. Thematic analysis identified four categories of focus of occupational therapy intervention: health promotion and prevention, increasing physical activity participation, modifying dietary intake and reducing the impact of obesity. Four categories of intervention strategies were also identified; assessment, modifying the environment, education and introducing and adapting occupations. The findings of this review suggest a comprehensive role for occupational therapy in addressing obesity. However, the paucity of outcome studies mean that significantly more research is required to further define and provide a strong evidence base for occupational therapy practice in this emerging field. © 2013 Occupational Therapy Australia.

  18. Testosterone Therapy: Review of Clinical Applications.

    2017-10-01

    Testosterone therapy is increasingly common in the United States, and many of these prescriptions are written by primary care physicians. There is conflicting evidence on the benefit of male testosterone therapy for age-related declines in testosterone. Physicians should not measure testosterone levels unless a patient has signs and symptoms of hypogonadism, such as loss of body hair, sexual dysfunction, hot flashes, or gynecomastia. Depressed mood, fatigue, decreased strength, and a decreased sense of vitality are less specific to male hypogonadism. Testosterone therapy should be initiated only after two morning total serum testosterone measurements show decreased levels, and all patients should be counseled on the potential risks and benefits before starting therapy. Potential benefits of therapy include increased libido, improved sexual function, improved mood and well-being, and increased muscle mass and bone density; however, there is little or mixed evidence confirming clinically significant benefits. The U.S. Food and Drug Administration warns that testosterone therapy may increase the risk of cardiovascular complications. Other possible risks include rising prostate-specific antigen levels, worsening lower urinary tract symptoms, polycythemia, and increased risk of venous thromboembolism. Patients receiving testosterone therapy should be monitored to ensure testosterone levels rise appropriately, clinical improvement occurs, and no complications develop. Testosterone therapy may also be used to treat hypoactive sexual desire disorder in postmenopausal women and to produce physical male sex characteristics in female-to-male transgender patients.

    Central retinal artery occlusion (CRAO) is an ophthalmologic emergency due to the sudden cessation of circulation to the inner retinal layer. Without immediate treatment, permanent blindness may ensue. Several treatment options exist, ranging from noninvasive medical management to thrombolysis. Nonetheless, ongoing debate exists regarding the best therapeutic strategy. The authors present the case of a 78-year-old woman with a medical history of hypercholesterolemia and rheumatoid arthritis who experienced complete loss of vision in her left eye. Following ophthalmologic evaluation demonstrating left CRAO, anterior chamber paracentesis was performed. Endovascular intervention was performed via local intra-arterial fibrinolysis with alteplase. Her vision returned to 20/20 following the procedure. In general, conventional therapies have not significantly improved patient outcomes. Several management options exist for CRAO. In general, conservative measures have not been reported to yield better patient outcomes as compared to the natural history of this medical emergency. Endovascular approaches are another option as observed with this case reported. In cases of CRAO, therapeutic strategies such as intra-arterial fibrinolysis utilize a local infusion of reactive tissue plasminogen activator directly at the site of occlusion via catheterization of the ophthalmic artery. Although several case series do show promising results after treating CRAO with intra-arterial fibrinolysis, further studies are required given the reports of complications.

    To investigate the clinical efficacy of individual endovascular management for the treatment of different traumatic pseudo aneurysms presenting as intractable epistaxis. For 14 consecutive patients with traumatic pseudo aneurysm presenting as refractory epistaxis, 15 endovascular procedures were performed. Digital subtraction angiography revealed that the pseudo aneurysms originated from the internal maxillary artery in eight patients; and all were treated with occlusion of the feeding artery. In six cases, they originated from the internal carotid artery (Inca); out of which, two were managed with detachable balloons, two with covered s tents, one by means of cavity embolization, and the remaining one with parent artery occlusion. All of these cases were followed up clinically from six to 18 months, with a mean follow up time of ten months; moreover, three cases were also followed with angiography. Complete cessation of bleeding was achieved in all the 15 instances (100%) immediately after the endovascular therapies. Of the six patients who suffered from Inca pseudo aneurysms, one presented with a permanent stroke and one had an episode of rebleeding requiring intervention. In patients presenting with a history of cranio cerebral trauma, traumatic pseudo aneurysm must be considered as a differential diagnosis. Individual endovascular treatment is a relatively safe, plausible, and reliable means of managing traumatic pseudo aneurysms

    Purpose: Technical essentials and therapeutic results of carotid stenting without cerebral protection are presented. Materials and methods: In 161 patients, 167 high grade carotid stenoses were stented, followed by percutaneous transluminal angioplasty, with subsequent evaluation of the clinical and angiographic results. Diffusion-weighted MRI was carried out in 108 patients to detect cerebral sequelae. Results: Endovascular therapy was successful (residual stenosis <25%) in 166 stenoses (99.4%). Twelve patients (7.5%) had cerebrovascular complications within the 30-day perioperative period, seven of which occurred during the procedure. After treatment, diffusion-weighted MRI disclosed at least one new cerebral lesion in 40 patients (37%), which were symptomatic in six patients. Conclusion: Even without cerebral protection, high grade carotid stenosis can be safely treated with stent-protected percutaneous angioplasty. Microemboli detected by postoperative MRI are infrequently symptomatic. (orig.)

    Full Text Available BACKGROUND: Since 1950, traditional Chinese medicine (TCM cupping therapy has been applied as a formal modality in hospitals throughout China and elsewhere in the world. Based on a previous systematic literature review of clinical studies on cupping therapy, this study presents a thorough review of randomized controlled trials (RCTs to evaluate the therapeutic effect of cupping therapy. METHOD: Six databases were searched for articles published through 2010. RCTs on cupping therapy for various diseases were included. Studies on cupping therapy combined with other TCM treatments versus non-TCM therapies were excluded. RESULTS: 135 RCTs published from 1992 through 2010 were identified. The studies were generally of low methodological quality. Diseases for which cupping therapy was commonly applied were herpes zoster, facial paralysis (Bell palsy, cough and dyspnea, acne, lumbar disc herniation, and cervical spondylosis. Wet cupping was used in most trials, followed by retained cupping, moving cupping, and flash cupping. Meta-analysis showed cupping therapy combined with other TCM treatments was significantly superior to other treatments alone in increasing the number of cured patients with herpes zoster, facial paralysis, acne, and cervical spondylosis. No serious adverse effects were reported in the trials. CONCLUSIONS: Numerous RCTs on cupping therapy have been conducted and published during the past decades. This review showed that cupping has potential effect in the treatment of herpes zoster and other specific conditions. However, further rigorously designed trials on its use for other conditions are warranted.

    Cancer is considered the second leading cause of death worldwide despite the progress made in early detection and advances in classical therapies. Advancing in the fight against cancer requires the development of novel strategies, and the suicide gene transfer to tumor cells is providing new possibilities for cancer therapy. In this manuscript, authors present an overview of suicide gene systems and the latest innovations done to enhance cancer suicide gene therapy strategies by i) improving vectors for targeted gene delivery using tissue specific promoter and receptors; ii) modification of the tropism; and iii) combining suicide genes and/or classical therapies for cancer. Finally, the authors highlight the main challenges to be addressed in the future. Even if many efforts are needed for suicide gene therapy to be a real alternative for cancer treatment, we believe that the significant progress made in the knowledge of cancer biology and characterization of cancer stem cells accompanied by the development of novel targeted vectors will enhance the effectiveness of this type of therapeutic strategy. Moreover, combined with current treatments, suicide gene therapy will improve the clinical outcome of patients with cancer in the future.

  15. Aortoenteric Fistula as a Complication of Open Reconstruction and Endovascular Repair of Abdominal Aorta

    Directory of Open Access Journals (Sweden)

    Marek Tagowski

    2014-01-01

    Full Text Available The paper intends to present a review of imaging characteristics of secondary aortoenteric fistula (AEF. Mechanical injury, infection, and adherence of a bowel segment to the aorta or aortic graft are major etiologic factors of AEF after open aortic repair. The pathogenesis of AEF formation after endovascular abdominal aortic repair is related to mechanical failure of the stent-graft, to stent graft infection, and to persistent pressurization of the aneurysmal sac. The major clinical manifestations of AEF comprise haematemesis, melaena, abdominal pain, sepsis, and fever. CT is the initial diagnostic modality of choice in a stable patient. However, the majority of reported CT appearances are not specific. In case of equivocal CT scans and clinical suspicion of AEF, scintigraphy, 67Ga citrate scans or 18F-FDG PET/CT is useful. Diagnostic accuracy of endoscopy in evaluation of AEF is low; nevertheless it allows to evaluate other than AEF etiologies of gastrointestinal bleeding. Without adequate therapy, AEF is lethal. Conventional surgical treatment is associated with high morbidity and mortality. The endovascular repair may be an option in hemodynamically unstable and high-risk surgical patients. We also illustrate an example of a secondary AEF with highly specific albeit rare radiologic picture from our institution.

  16. A Systematic Review of Bright Light Therapy for Eating Disorders.

    2016-10-27

    Bright light therapy is a noninvasive biological intervention for disorders with nonnormative circadian features. Eating disorders, particularly those with binge-eating and night-eating features, have documented nonnormative circadian eating and mood patterns, suggesting that bright light therapy may be an efficacious stand-alone or adjunctive intervention. The purpose of this systematic literature review, using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, was (1) to evaluate the state of the empirical treatment outcome literature on bright light therapy for eating disorders and (2) to explore the timing of eating behavior, mood, and sleep-related symptom change so as to understand potential mechanisms of bright light therapy action in the context of eating disorder treatment. A comprehensive literature search using PsycInfo and PubMed/MEDLINE was conducted in April 2016 with no date restrictions to identify studies published using bright light therapy as a treatment for eating disorders. Keywords included combinations of terms describing disordered eating (eating disorder, anorexia nervosa, bulimia nervosa, binge eating, binge, eating behavior, eating, and night eating) and the use of bright light therapy (bright light therapy, light therapy, phototherapy). After excluding duplicates, 34 articles were reviewed for inclusion. 14 published studies of bright light therapy for eating disorders met inclusion criteria (included participants with an eating disorder/disordered-eating behaviors; presented as a case study, case series, open-label clinical trial, or randomized/nonrandomized controlled trial; written in English; and published and available by the time of manuscript review). Results suggest that bright light therapy is potentially effective at improving both disordered-eating behavior and mood acutely, although the timing of symptom response and the duration of treatment effects remain unknown. Future research should

    Traumatic intracranial pseudoaneurysm is a rare complication of blunt trauma. It is even more rare when it presents as epistaxis. Massive epistaxis of a ruptured intracranial internal carotid artery pseudoaneurysm is a major cause of mortality, which requires emergency intervention. We report a case of traumatic intracranial internal carotid artery pseudoaneurysm secondary to skull base fracture, which presented with delayed onset of epistaxis. This was successfully treated by primary endovascular coil embolization. We discuss endovascular treatment options and review the literature. PMID:26818170

    Objective. To evaluate the technical success, safety, and outcome of endovascular embolization procedure in management of visceral artery pseudoaneurysms. Materials and Methods. 46 patients were treated for 53 visceral pseudoaneurysms at our institution. Preliminary diagnostic workup in all cases was performed by contrast enhanced abdominal CT scan and/or duplex ultrasound. In all patients, embolization was performed as per the standard departmental protocol. For data collection, medical records and radiology reports of all patients were retrospectively reviewed. Technical success, safety, and outcome of the procedure were analyzed. Results. Out of 46 patients, 13 were females and 33 were males. Mean patient age was 44.79 ± 13.9 years and mean pseudoaneurysm size was 35 ± 19.5 mm. Technical success rate for endovascular visceral pseudoaneurysm coiling was 93.47% (n = 43). Complication rate was 6.52% (n = 3). Followup was done for a mean duration of 21 ± 1.6 months (0.5–69 months). Complete resolution of symptoms or improvement in clinical condition was seen in 36 patients (80%) out of those 45 in whom procedure was technically successful. Conclusion. Results of embolization of visceral artery pseudoaneurysms with coils at our center showed high success rate and good short term outcome

    Full Text Available Endovascular aortic/aneurysm repair (EVAR was introduced into clinical practice at the beginning of the nineties. Its fast development had a great influence on clinicians, vascular surgeons and interventional radiologists, educational curriculums, patients, industry and medical insurance. The aim of this paper is to present the contribution of clinicians and industry to the development and advancement of endovascular aortic repair over the last 20 years. This review article presents the development of EVAR by focusing on the contribution of physicians, surgeons and interventional radiologists in the creation of the new field of vascular surgery termed hybrid vascular surgery, and also the contribution of technological advancement by a significant help of industrial representatives – engineers and their counselors. This article also analyzes studies conducted in order to compare the successfulness of EVAR with up-to-now applied open surgical repair of aortic aneurysms, and some treatment techniques of other aortic diseases. During the first two decades of its development the EVAR method was rapidly progressing and was adopted concurrently with the expansion of technology. Owing to large randomized studies, early and long-term results indicate specific complications of this method, thus influencing further technological improvement and defining risk patients groups in whom the use of the technique should be avoided. Good results are insured only in centers, specialized in vascular surgery, which have on their disposal adequate conditions for solving all complications associated with this method.

    Mind-body therapies are often used by people with autism spectrum disorders (ASD). However, there has been little examination into which types of mind-body therapies have been investigated for people with ASD and for what purposes. A systematic review was conducted to evaluate the existing evidence for mind-body therapies for people with ASD, particularly to determine the types of mind-body therapies used and the outcomes that are targeted. PubMed, PsychInfo, and Scopus were searched using terms for ASD and mind-body therapies. Sixteen studies were selected for review; these studies tested interventions using mindfulness, meditation, yoga, Nei Yang Gong, and acceptance commitment therapy. Most study outcomes targeted behavior, psychological symptoms, and quality of life for children and adults with ASD as well as their parents. There was little overlap between studies on the types of mind-body therapies used and associated outcomes, and only three of the studies were randomized controlled trials. Most studies were small and uncontrolled. Some studies modified the mind-body therapies to increase accessibility for people with ASD. The evidence for mind-body therapies for people with ASD is limited and would benefit from larger randomized controlled trials.

    Six Centers for Radiological Physics (CRP) have performed over 250 dosimetric site reviews at institutions participating in the Division of Cancer Control and Rehabilitation therapy networks and/or as affiliates in Oncology Group Clinical trials. For the initial site visits, institution stated output calibration was within +- 3% of that measured by the CRPs for 87% of the therapy machines reviewed. The accuracy of methods utilized in calculating tumor dose were assessed by using a set of reference cases of varying complexity. Many institutions have received multiple reviews and a significant reduction in the variance of machine calibration and calculated tumor dose for the reference cases is evident

    Full Text Available This review aims to establish the impact of oxygen therapy on dyspnoea, health-related quality of life (HRQoL, exercise capacity and mortality in interstitial lung disease (ILD. We included studies that compared oxygen therapy to no oxygen therapy in adults with ILD. No limitations were placed on study design or intervention type. Two reviewers independently evaluated studies for inclusion, assessed risk of bias and extracted data. The primary outcome was dyspnoea. Eight studies evaluated the acute effects of oxygen (n=1509. There was no effect of oxygen therapy on modified Borg dyspnoea score at end exercise (mean difference (MD −0.06 units, 95% CI −0.24–0.13; two studies, n=27. However, effects on exercise outcomes consistently favoured oxygen therapy. One study showed reduction in dyspnoea at rest with oxygen in patients who were acutely unwell (MD visual analogue scale 30 mm versus 48 mm, p<0.05; n=10. Four studies of long-term oxygen therapy (n=2670 had high risk of bias and no inferences could be drawn. This systematic review showed no effects of oxygen therapy on dyspnoea during exercise in ILD, although exercise capacity was increased. Future trials should evaluate whether acute improvements in exercise capacity with oxygen can be translated into improved physical activity and HRQoL.

  6. Music therapy in rehabilitation: a narrative review (2004-2014

    María del Carmen Gómez Álvaro

    2015-04-01

    Full Text Available During this decade, there has been an increased on research about music therapy interventions as a therapeutic tool.  Narrative reviews that have been published till nowadays show the implications and effectiveness of interventions based on music therapy as a rehabilitative intervention strategy. However, due to their narrowness they lack of a general perspective of the construct. Moreover, these reviews do not include in their criteria the search term “music therapy”, thereby excluding studies that support the effectiveness of music therapy in rehabilitation. Therefore, the aim of this paper is to solve this issue including and reviewing findings of published research that have been excluded from previous reviews over the last ten years. There were two research questions: For which disorders is music therapy more effective? What are the benefits of music therapy in rehabilitation? In order to answer these questions, we conducted a literature review in academic databases, such as Academic Search Complete, Medline, and Science Direct, including the search term "music therapy".   Furthermore, papers fulfilling inclusion criteria, such as empirical studies, written in English, which used music as therapeutic stimulation were reviewed. We found twenty-four studies in which we analyzed the participants (experimental vs. control, the results, and limitations. We conclude, cautiously, that music therapy may help in the rehabilitation of cognitive, motor, and sensory functions of brain damage, the rehabilitation of schizophrenia and primary depression; and amelioration of neurodegenerative disorders, autism spectrum disorders, substance abuse and other pathologies. We recommend overcoming the methodological limitations of these studies and the suitability of cross-cultural studies.

    2017-01-01

    Music therapy has been employed as a therapeutic intervention to facilitate healing across a variety of clinical populations. There is theoretical and empirical evidence to suggest that individuals with trauma exposure and Posttraumatic Stress Disorder (PTSD), a condition characterized by enduring symptoms of distressing memory intrusions, avoidance, emotional disturbance, and hyperarousal, may derive benefits from music therapy. The current narrative review describes the practice of music therapy and presents a theoretically-informed assessment and model of music therapy as a tool for addressing symptoms of PTSD. The review also presents key empirical studies that support the theoretical assessment. Social, cognitive, and neurobiological mechanisms (e.g., community building, emotion regulation, increased pleasure, anxiety reduction) that promote music therapy's efficacy as an adjunctive treatment for individuals with posttraumatic stress are discussed. It is concluded that music therapy may be a useful therapeutic tool to reduce symptoms and improve functioning among individuals with trauma exposure and PTSD, though more rigorous empirical study is required. In addition, music therapy may help foster resilience and engage individuals who struggle with stigma associated with seeking professional help. Practical recommendations for incorporating music therapy into clinical practice are offered along with several suggestions for future research.

    2009-06-01

    The objective of this review is to evaluate the evidence on the effects of Spinal Manipulative Therapy (SMT) on back pain and other related symptoms during pregnancy. A literature search was conducted using Pubmed, Manual, Alternative and Natural Therapy Index System, Cumulated Index to Nursing and Allied Health, Index to Chiropractic Literature, the Cochrane Library, and Google Scholar. In addition hand searches and reference tracking were also performed, and the citation list was assessed for comprehensiveness by content experts. This review was limited to peer-reviewed manuscripts published in English from 1966 until September 2008. The initial search strategy yielded 140 citations of which 12 studies were reviewed for quality. The methodological quality of the included studies was assessed independently using quality checklists of the Scottish Intercollegiate Guidelines Network and Council on Chiropractic Guidelines and Practice Parameters. The review indicates that the use of SMT during pregnancy to reduce back pain and other related symptoms is supported by limited evidence. Overall, this body of evidence is best described as emergent. However, since effective treatments for pregnancy-related back pain are limited, clinicians may want to consider SMT as a treatment option, if no contraindications are present. Obstetricians & Gynecologists, Family Physicians After completion of this article, the reader should be able to describe the concepts of spinal manipulative therapy and types of symptoms for which it might be considered in pregnancy, explain the quality of available research on the use of spinal manipulative therapy, and plan to discuss this therapy with interested pregnant patients.

    Full Text Available Jennifer Yeung, Michael HolinstatCardeza Foundation for Hematologic Research, Department of Medicine, Thomas Jefferson University, Philadelphia, PA, USAAbstract: Antiplatelet therapy remains the mainstay in preventing aberrant platelet activation in pathophysiological conditions such as myocardial infarction, ischemia, and stroke. Although there has been significant advancement in antiplatelet therapeutic approaches, aspirin still remains the gold standard treatment in the clinical setting. Limitations in safety, efficacy, and tolerability have precluded many of the antiplatelet inhibitors from use in patients. Unforeseen incidences of increased bleeding risk and recurrent arterial thrombosis observed in patients have hampered the development of superior next generation antiplatelet therapies. The pharmacokinetic and pharmacodynamic profiles have also limited the effectiveness of a number of antiplatelet inhibitors currently in use due to variability in metabolism, time to onset, and reversibility. A focused effort in the development of newer antiplatelet therapies to address some of these shortcomings has resulted in a significant number of potential antiplatelet drugs which target enzymes (phosphodiesterase, cyclooxygenase, receptors (purinergic, prostaglandins, protease-activated receptors, thromboxane, and glycoproteins (αIIbß3, GPVI, vWF, GPIb in the platelet. The validation and search for newer antiplatelet therapeutic approaches proven to be superior to aspirin is still ongoing and should yield a better pharmacodynamic profile with fewer untoward side-effects to what is currently in use today.Keywords: platelet aggregation inhibitors, blood platelets, purinergic P2Y receptor antagonists, receptor, PAR-1, platelet glycoprotein GPIIb-IIIa, thrombosis

    2017-01-01

    Infarction of the symmetrical middle cerebellar peduncles is often induced by ischemic cerebrovascular disease. Adams described the anterior inferior cerebellar artery (AICA) syndrome as early as 1943, but clinical and imaging studies following this failed to shed more light regarding the condition until the advent of magnetic resonance imaging that comprehension regarding AICA improved significantly. Infarction of the middle cerebellar peduncles (MCP) is uncommon and the endovascular treatment of this condition is even more rare. We studied 4 patients with simultaneous bilateral cerebellar infarction of whom 2 received intracranial vascular therapy and demonstrated improvement in symptoms. Our findings suggest that patients with vertebral basilar artery stenosis with potential bilateral cerebellar infarction may benefit from endovascular treatment. PMID:28064332

    Surgical treatment poses a high risk to patients with concomitant aortic coarctation and dissection, and an interventional approach could be an alternative. We describe the case of a 52-year-old man with a long history of untreated hypertension and aortic coarctation who emergently presented at our institution with an acute Stanford type B dissection. The patient's elevated serum creatinine level, perfusion deficit in the right lower limb, and hypertension did not respond to medical therapy, and he did not consent to surgery. By endovascular means, we used a self-expandable stent-graft to cover the entry point of the dissection; then, we deployed a balloon-expandable bare-metal stent to correct residual stenosis. To our knowledge, this is the first report of the endovascular treatment of aortic coarctation complicated by type B dissection.

    A diverse literature addresses elements of conversation therapy in aphasia including intervention rooted in conversation analysis, partner training, group therapy and behavioural intervention. Currently there is no resource for clinicians or researchers that defines and organizes this information into a coherent synopsis describing various conversation therapy practices. To organize information from varied sources into a descriptive overview of conversation therapy for aphasia. Academic search engines were employed to identify research articles published between 1950 and September 2013 reporting on conversation therapy for aphasia. Thirty articles met criteria for review and were identified as primary sources for the qualitative review. Using qualitative methodology, relevant data were extracted from articles and categories were identified to create a descriptive taxonomy of conversation therapy for aphasia. Conversation interventions were divided into descriptive categories including: treatment participants (person with aphasia, partner, dyad), primary guiding orientation (conversation analysis, social model, behavioural, relationship centred), service delivery (individual, group), focus of intervention (generic/individualized; problem/solution oriented; compensatory), training methods (explicit/implicit; external/embedded), activities or tasks, and outcomes measured. Finally, articles were categorized by research design. There was marked variation in conversation therapy approaches and outcome measures reported and a notable gap in information about one-on-one conversation therapy for individuals with aphasia. This review provides a description of various conversation therapy approaches and identified gaps in the existing literature. Valid measures of natural conversation, research on one-on-one conversation approaches for individuals with aphasia, and a systematic body of evidence consisting of high quality research are needed. © 2014 Royal College of Speech

    Because of their biological effects fast neutrons are most effective in treating large, slow-growing tumours which are resistant to conventional X-radiation. Patients are treated typically 3-4 times per week for 4-5 weeks (sometimes in combination with X-radiation) for a variety of conditions such as carcinomas of the head and neck, salivary gland, paranasal sinus and breast; soft tissue, bone and uterine sarcomas and malignant melanomas. It is estimated that about 27,000 patients have undergone fast neutron therapy to date

    The purpose of this study was to perform a systematic review of clinical trials of spinal manipulative therapy for adolescent idiopathic scoliosis. Search strategies were developed for PubMed, CINHAL, and CENTRAL databases. Studies were included through June 2016 if they were prospective trials that evaluated spinal manipulative therapy (eg, chiropractic, osteopathic, physical therapy) for adolescent idiopathic scoliosis. Data were extracted and assessed by 2 independent reviewers. Cochrane risk of bias tools were used to assess the quality of the included studies. Data were reported qualitatively because heterogeneity prevented statistical pooling. Four studies satisfied the inclusion criteria and were critically appraised. The findings of the included studies indicated that spinal manipulative therapy might be effective for preventing curve progression or reducing Cobb angle. However, the lack of controls and small sample sizes precluded robust estimation of the interventions' effect sizes. There is currently insufficient evidence to establish whether spinal manipulative therapy may be beneficial for adolescent idiopathic scoliosis. The results of the included studies suggest that spinal manipulative therapy may be a promising treatment, but these studies were all at substantial risk of bias. Further high-quality studies are warranted to conclusively determine if spinal manipulative therapy may be effective in the management of adolescent idiopathic scoliosis. Copyright © 2017.

The patient was a white 72-year-old man with pulmonary tuberculosis and a former smoker with hypertension, chronic renal failure, and dyslipidemia. A computed tomographic scan of the abdomen and pelvis revealed a left paravertebral cavity with fluid content and involvement of vertebrae L2–L4. After a surgical repair attempt, the patient was treated with the implant of a bifurcated endoprosthesis. Because it is unlikely that any center has extensive experience in the management of this rare manifestation of the disease, we reviewed the literature for similar cases.

    We report on workflow and process-based performance measures and their effect on clinical outcome in Solitaire FR Thrombectomy for Acute Revascularization (STAR), a multicenter, prospective, single-arm study of Solitaire FR thrombectomy in large vessel anterior circulation stroke patients. Two hundred two patients were enrolled across 14 centers in Europe, Canada, and Australia. The following time intervals were measured: stroke onset to hospital arrival, hospital arrival to baseline imaging, baseline imaging to groin puncture, groin puncture to first stent deployment, and first stent deployment to reperfusion. Effects of time of day, general anesthesia use, and multimodal imaging on workflow were evaluated. Patient characteristics and workflow processes associated with prolonged interval times and good clinical outcome (90-day modified Rankin score, 0-2) were analyzed. Median times were onset of stroke to hospital arrival, 123 minutes (interquartile range, 163 minutes); hospital arrival to thrombolysis in cerebral infarction (TICI) 2b/3 or final digital subtraction angiography, 133 minutes (interquartile range, 99 minutes); and baseline imaging to groin puncture, 86 minutes (interquartile range, 24 minutes). Time from baseline imaging to puncture was prolonged in patients receiving intravenous tissue-type plasminogen activator (32-minute mean delay) and when magnetic resonance-based imaging at baseline was used (18-minute mean delay). Extracranial carotid disease delayed puncture to first stent deployment time on average by 25 minutes. For each 1-hour increase in stroke onset to final digital subtraction angiography (or TICI 2b/3) time, odds of good clinical outcome decreased by 38%. Interval times in the STAR study reflect current intra-arterial therapy for patients with acute ischemic stroke. Improving workflow metrics can further improve clinical outcome. http://www.clinicaltrials.gov. Unique identifier: NCT01327989. © 2014 American Heart Association, Inc.

    2014-01-01

    Music therapists are challenged to present evidence on the efficacy of music therapy treatment and incorporate the best available research evidence to make informed healthcare and treatment decisions. Higher standards of evidence can come from a variety of sources including systematic reviews. To define and describe a range of research review methods using examples from music therapy and related literature, with emphasis on the systematic review. In addition, the authors provide a detailed overview of methodological processes for conducting and reporting systematic reviews in music therapy. The systematic review process is described in five steps. Step 1 identifies the research plan and operationalized research question(s). Step 2 illustrates the identification and organization of the existing literature related to the question(s). Step 3 details coding of data extracted from the literature. Step 4 explains the synthesis of coded findings and analysis to answer the research question(s). Step 5 describes the strength of evidence evaluation and results presentation for practice recommendations. Music therapists are encouraged to develop and conduct systematic reviews. This methodology contributes to review outcome credibility and can determine how information is interpreted and used by clinicians, clients or patients, and policy makers. A systematic review is a methodologically rigorous research method used to organize and evaluate extant literature related to a clinical problem. Systematic reviews can assist music therapists in managing the ever-increasing literature, making well-informed evidence based practice and research decisions, and translating existing music-based and nonmusic based literature to clinical practice and research development. © the American Music Therapy Association 2014.

    In this paper an endovascular measurement system used for intraoperative cerebral blood flow monitoring is described. The system is based on a Volcano ComboMap Pressure and Flow System extended with analogue-to-digital converter and PC laptop. A series of measurements performed in patients with cerebrovascular pathologies allows us to introduce “velocity-pressure” and “flow rate-energy flow rate” diagrams as important characteristics of the blood flow. The measurement system presented here can be used as an additional instrument in neurosurgery for assessment and monitoring of the operation procedure. Clinical data obtained with the system are used for construction of mathematical models and patient-specific simulations. The monitoring of the blood flow parameters during endovascular interventions was approved by the Ethics Committee at the Meshalkin Novosibirsk Research Institute of Circulation Pathology and included in certain surgical protocols for pre-, intra- and postoperative examinations.

    Cancer is characterized by the dysregulation of cell signaling pathways at several steps. The majority of current anticancer therapies involve the modulation of a single target. A tumor-targeting drug-delivery system consists of a tumor detection moiety and a cytotoxic material joined directly or through a suitable linker to form a conjugate. Photodynamic therapy has been used for more than 100 years to treat tumors. One of the present goals of photodynamic therapy research is to enhance the selective targeting of tumor cells in order to reduce the risk and extension of unwanted side-effects, caused by normal cell damage. Sonodynamic therapy is a promising new treatment for patients with cancer. It treats cancer with ultrasound and sonosensitive agents. Porphyrin compounds often serve as photosensitive and sonosensitive agents. The combination of these two methods makes cancer treatment more effective. The present review provides an overview of photodynamic therapy, sonodynamic therapy, sono-photodynamic therapy and the four sensitizers which are suitable candidates for combined sono-photodynamic therapy.

    A cost comparison of the surgical clipping and endovascular coiling of unruptured intracranial aneurysms (UIAs), and the identification of the principal cost determinants of these treatments. This study conducted a retrospective review of data from a series of patients who underwent surgical clipping or endovascular coiling of UIAs between January 2011 and May 2014. The medical records, radiological data, and hospital cost data were all examined. When comparing the total hospital costs for surgical clipping of a single UIA (n=188) and endovascular coiling of a single UIA (n=188), surgical treatment [mean±standard deviation (SD) : ₩8,280,000±1,490,000] resulted in significantly lower total hospital costs than endovascular treatment (mean±SD : ₩11,700,000±3,050,000, p<0.001). In a multi regression analysis, the factors significantly associated with the total hospital costs for endovascular treatment were the aneurysm diameter (p<0.001) and patient age (p=0.014). For the endovascular group, a Pearson correlation analysis revealed a strong positive correlation (r=0.77) between the aneurysm diameter and the total hospital costs, while a simple linear regression provided the equation, y (₩)=6,658,630+855,250x (mm), where y represents the total hospital costs and x is the aneurysm diameter. In South Korea, the total hospital costs for the surgical clipping of UIAs were found to be lower than those for endovascular coiling when the surgical results were favorable without significant complications. Plus, a strong positive correlation was noted between an increase in the aneurysm diameter and a dramatic increase in the costs of endovascular coiling.

    To evaluate the effects of therapeutic exercise on pain, stiffness, quality of life, physical function, disease activity, health-related fitness and cardiovascular risk factors in adults with spondyloarthritis (SpA). Electronic databases (Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE/PubMed, PEDro, AMED, CINAHL) were systematically searched from inception to October 2013 using medical subject headings and keywords. This was supplemented by searching conference abstracts and a hand search of reference lists of included studies. Randomised and quasi-randomised studies of adults with SpA in which at least one of the comparison groups received an exercise intervention were included. Outcomes of interest were pain, stiffness, quality of life, physical function and disease activity. Secondary outcomes were health-related fitness and cardiovascular risk factors. Two reviewers independently screened studies for inclusion. Methodological quality was assessed by two reviewers using the Cochrane risk of bias tool and the PEDro scale. Twenty-four studies, involving 1,498 participants, were included. Meta-analyses were not undertaken due to clinical heterogeneity, and this review focuses on qualitative synthesis. Moderate evidence supports exercise interventions in improving physical function, disease activity and chest expansion compared to controls; there is low-level evidence of improved pain, stiffness, spinal mobility and cardiorespiratory function. Supervised group exercise yields better outcomes than unsupervised home exercise. The addition of aerobic components to flexibility programmes improves cardiorespiratory outcomes, but not cardiovascular risk factors. The most effective exercise protocol remains unclear. Current evidence suggests that therapeutic exercises are beneficial for adults with ankylosing spondylitis; effects on other SpA subtypes are unknown.

    One of today's controversies remains the prevention of recurrent diverticulitis. Current guidelines advise a conservative approach, based on studies showing low recurrence rates and a high operative morbidity and mortality. Conservative measures in prevention recurrence are dietary advises and medical therapies, including probiotics and 5-aminosalicylic acid. The aim of this systematic review is to assess whether medical or dietary therapies can prevent recurrent diverticulitis after a primary episode of acute diverticulitis. METHOD AND SEARCH STRATEGY: We searched different databases for papers published between January 1966 and January 2011. Clinical studies were eligible for inclusion if they assessed the prevention of recurrent diverticulitis with a medical or dietary therapy. Exclusion criteria were studies without a control group. Three randomized controlled trials (RCT), all with a Jadad quality score of 2 out of 5, were included in this systematic review. Mesalazine results in significantly less disease recurrence and fewer symptoms after an acute episode. The use of probiotics decreases symptoms but does not reduce recurrence. No difference in effect is seen when Balsalazide is added to probiotics compared to probiotics only. No relevant studies on dietary therapy/advices or antibiotics for prevention of recurrent diverticulitis were found. The evidence that supports medical therapy to prevent recurrent diverticulitis is of poor quality. Treatment with 5-aminosalicylic acid seems promising. Based on current data, no recommendation of any non-operative relapse prevention therapy for diverticular disease can be made.

    There is evidence of the increasing use of complementary and alternative medicine by Australians diagnosed with cancer. Given the increasing desire of cancer patients to use complementary and alternative medicine, it is important that clinicians have a good understanding of the evidence available in this field. This critical review aims to provide an overview of the current evidence pertaining to a range of complementary therapies that are used in a supportive role in the treatment of cancer patients. Treatment methods considered are acupuncture, music therapy, massage and touch therapies and psychological interventions. The efficacy of these complementary therapies in terms of improvement in symptoms and quality of life is examined. Evidence that relates to an effect on immune function and survival is also investigated.

    Spiritism is the third most common religion in Brazil, and its therapies have been used by millions worldwide. These therapies are based on therapeutic resources including prayer, laying on of hands, fluidotherapy (magnetized water), charity/volunteering, spirit education/moral values, and disobsession (spirit release therapy). This paper presents a systematic review of the current literature on the relationship among health outcomes and 6 predictors: prayer, laying on of hands, magnetized/fluidic water, charity/volunteering, spirit education (virtuous life and positive affect), and spirit release therapy. All articles were analyzed according to inclusion/exclusion criteria, Newcastle-Ottawa and Jadad score. At present, there is moderate to strong evidence that volunteering and positive affect are linked to better health outcomes. Furthermore, laying on of hands, virtuous life, and praying for oneself also seem to be associated to positive findings. Nevertheless, there is a lack of studies on magnetized water and spirit release therapy. In summary, science is indirectly demonstrating that some of these therapies can be associated to better health outcomes and that other therapies have been overlooked or poorly investigated. Further studies in this field could contribute to the disciplines of Complementary and Alternative Medicine by investigating the relationship between body, mind, and soul/spirit.

    Critical limb ischemia (CLI) is an endstage manifestation of peripheral artery disease (PAD) and typically describes patients with ischemic rest pain (Rutherford Category 4), or patients with ischemic skin lesions, either ulcers or gangrene (Rutherford Category 5-6). CLI due to infrapopliteal lesions is often not a good indication for infrageniculate bypass surgery placement, due to the presence of prohibitive comorbidities, inadequate conduit, and lack of suitable distal targets for revascularization. Therefore, CLI patients due to blockage of below-the-knee arteries are in benefit of the endovascular approach. Infrapopliteal PTA became feasible with the introduction of low-profile peripheral balloon systems and the use of coronary balloons. Stent implantation, however, is generally reserved for cases with a suboptimal outcome after PTA (i.e. >50% residual stenosis, flow-limiting dissection). Because of the fear that early thrombosis and late luminal loss due to intimal hyperplasia formation will potentially lead to insufficient long-term patency rates, efforts to extend the range of endovascular approaches to CLI are presently focused on. Cryoplasty, scoring balloon angioplasty, excimer laser therapy and atherectomy using different types of atherectomy devices have been introduced. The current article provides an overview of the endovascular treatment strategies for infrapopliteal lesions in patients with CLI.

    Improved endovascular embolization of vascular conditions can generate better patient outcomes and minimize the need for repeat procedures. However, many embolic materials, such as metallic coils or liquid embolic agents, are associated with limitations and complications such as breakthrough bleeding, coil migration, coil compaction, recanalization, adhesion of the catheter to the embolic agent, or toxicity. Here, we engineered a shear-thinning biomaterial (STB), a nanocomposite hydrogel containing gelatin and silicate nanoplatelets, to function as an embolic agent for endovascular embolization procedures. STBs are injectable through clinical catheters and needles and have hemostatic activity comparable to metallic coils, the current gold standard. In addition, STBs withstand physiological pressures without fragmentation or displacement in elastomeric channels in vitro and in explant vessels ex vivo. In vitro experiments also indicated that STB embolization did not rely on intrinsic thrombosis as coils did for occlusion, suggesting that the biomaterial may be suitable for use in patients on anticoagulation therapy or those with coagulopathy. Using computed tomography imaging, the biomaterial was shown to fully occlude murine and porcine vasculature in vivo and remain at the site of injection without fragmentation or nontarget embolization. Given the advantages of rapid delivery, in vivo stability, and independent occlusion that does not rely on intrinsic thrombosis, STBs offer an alternative gel-based embolic agent with translational potential for endovascular embolization.

  5. Endovascular surgery in Marfan syndrome: CON.

    2017-11-01

    The frequency of endovascular stent grafting procedures to treat various conditions of the thoracic aorta has increased dramatically over the past three decades. Stent grafting has been applied on a limited basis in patients with Marfan syndrome and other connective tissue disorders, despite recommendations from current guidelines and expert consensus statements against its use in this setting. A review of publications reporting outcomes after stent grafting of the descending thoracic aorta in Marfan patients with acute or chronic aortic dissection indicates that these procedures can be accomplished with rates of early mortality, stroke and spinal cord ischemic injury that are comparable to those observed in patients who do not have Marfan syndrome. However, the rates of primary treatment failure (principally endoleak), secondary treatment failure, need for open repair and late death among the Marfan patients are substantially higher than those observed in patients without this condition. In addition, the rates of retrograde aortic dissection and development of stent-graft induced new entry (SINE), are also greater among patients with Marfan syndrome. All of these findings argue strongly against the routine use of endovascular grafts in Marfan patients with type B or residual type A dissection. Few data are available to assess the role of endografting in Marfan patients with aneurysmal disease, but the progressive aortic dilatation noted in these patients argues strongly against its use in this setting as well. At present, the available data indicate that there is no justification for elective stent grafting in Marfan patients with aortic dissection or aneurysm. The only reasonable indications for primary aortic stent grafting are in the setting of acute aortic dissection or rupture, where the intervention is considered life-saving and rarely, considering the relatively young age of these patients, where the risk of open operation is considered to be prohibitive.

  6. Treatment, Therapy and Management of Metabolic Epilepsy: A Systematic Review

    2018-03-01

    Full Text Available Metabolic epilepsy is a metabolic abnormality which is associated with an increased risk of epilepsy development in affected individuals. Commonly used antiepileptic drugs are typically ineffective against metabolic epilepsy as they do not address its root cause. Presently, there is no review available which summarizes all the treatment options for metabolic epilepsy. Thus, we systematically reviewed literature which reported on the treatment, therapy and management of metabolic epilepsy from four databases, namely PubMed, Springer, Scopus and ScienceDirect. After applying our inclusion and exclusion criteria as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA guidelines, we reviewed a total of 43 articles. Based on the reviewed articles, we summarized the methods used for the treatment, therapy and management of metabolic epilepsy. These methods were tailored to address the root causes of the metabolic disturbances rather than targeting the epilepsy phenotype alone. Diet modification and dietary supplementation, alone or in combination with antiepileptic drugs, are used in tackling the different types of metabolic epilepsy. Identification, treatment, therapy and management of the underlying metabolic derangements can improve behavior, cognitive function and reduce seizure frequency and/or severity in patients.

  7. Use of endovascular embolization to treat a ruptured arteriovenous malformation in a pregnant woman: a case report

    Directory of Open Access Journals (Sweden)

    Jermakowicz Walter J

    2012-04-01

    Full Text Available Abstract Introduction Pregnancy has been linked to increased rates of arteriovenous malformation rupture. This link remains a matter of debate and very few studies have addressed the management of arteriovenous malformation in pregnancy. Unruptured arteriovenous malformations in pregnant woman generally warrant conservative management due to the low rupture risk. When pregnant women present with ruptured arteriovenous malformation, however, surgery is often indicated due to the increased risk of re-rupture and associated mortality. Endovascular embolization is widely accepted as an important component of contemporary, multimodal therapy for arteriovenous malformations. Although rarely curative, embolization can facilitate subsequent surgical resection or radiosurgery. No previous reports have been devoted to the endovascular management of an arteriovenous malformation in a pregnant woman. Case presentation A 23-year-old Caucasian woman presented with headache and visual disturbance after the rupture of a left parieto-occipital arteriovenous malformation in the 22nd week of her pregnancy. After involving high-risk obstetric consultants and taking precautions to shield the fetus from ionizing radiation, we proceeded with a single stage of endovascular embolization followed soon after by open surgical resection of the arteriovenous malformation. There were several goals for the angiography in this patient: to better understand the anatomy of the arteriovenous malformation, including the number and orientation of feeding arteries and draining veins; to look for associated pre-nidal or intra-nidal aneurysms; and to partially embolize the arteriovenous malformation via safely-accessible feeders to facilitate surgical resection and minimize blood loss and operative morbidity. Conclusion From our experience and review of the literature, we maintain that ruptured arteriovenous malformations in pregnancy may be managed in a similar manner to those in non

    A series of five innovative experiments conducted by Wirth et al. which examined the effect of various complementary healing interventions on the reepithelialization rate of full thickness human dermal wounds was assessed as to specific methodological and related factors. The treatment interventions utilized in the series included experimental derivatives of the Therapeutic Touch (TT), Reiki, LeShan, and Intercessory Prayer techniques. The results of the series indicated statistical significance for the initial two experiments and nonsignificance or reverse significance for the remaining three studies. This review article examines the methodological designs of the series of studies, along with the TT practitioners' phenomenologically based journal reports, to provide potential contributing correlative factors for the differential results obtained. These factors include: (1) methodological design restrictions, (2) a transference/inhibitory effect (3) the influence of experimental assistants, (4) healer visualization /imagery techniques, (5) variations in subject populations, and (6) a potential cancellation effect. While the placebo controlled double-blind methodological designs used in the series were as stringent as those used in other fields of scientific inquiry, the overall results of the experiments were inconclusive in establishing the efficacy of the treatment interventions for accelerating the rate of reepithelialization of full thickness dermal wounds.

Despite better understanding of the biology and intense research in the treatment of these cancers, the long-term survival remains poor both in the locally advanced and metastatic settings. The addition of combined modality strategies has resulted in modest improvement in 5-year survival rates. A number of biologic agents targeting epidermal-derived growth factor receptor, vascular endothelial derived growth factor and its receptor, and mammalian target of rapamycin (mTOR are being currently evaluated in Phase II and III clinical trials. Some of these, like trastuzumab, cetuximab, and bevacizumab, have shown promising results.

    Atherosclerotic peripheral arterial disease (PAD) is prevalent affecting up to 16% of the population aged 55 years or older. Endovascular intervention for the treatment of limb ischemia has become the first line therapy but in Pakistan it is in embryonic stage due to dearth of trained persons and dedicated centres. This study was conducted to evaluate procedural success and early outcome of endovascular treatment of peripheral vascular disease. Methods: A prospective single arm multicentre study was conducted at the National Institute of Cardiovascular Disease and National Medical Centre, Karachi, Pakistan from January 2013 to June 2014. A total of 25 patients were enrolled in the study that underwent endovascular treatment. Out of 25 patients 23 (92%) had critical limb ischemia (CLI) as per TASC II classification (A to D) and 2 (8%) had carotid lesion with history of TIA. Patients of acute limb ischemia and stroke were excluded. Ankle brachial index (ABI) was classified as normal (0.9-1.3), mild (0.7-0.9), moderate (0.4-0.69), severe (<0.4). Outcome was taken as immediate success and symptoms, amputation of limb among CLI patients and incidence of stroke in patients with carotid artery lesion at end of six months. Results: Among aortoiliac, femoropopliteal and tibioperoneal lesions, tibioperoneal lesions at six months were found to be more symptomatic 6 (86%) and amputation 4 (57%). Two carotid lesions at follow up were asymptomatic without stroke. Conclusion: Endovascular treatment of peripheral vascular lesions, i.e., aortoiliac, femoropopliteal tibioperoneal and carotid lesions were satisfactory in immediate outcome. Tibioperoneal lesions were more symptomatic and limb amputation at six months. (author)

    Full Text Available Background and Purpose: Endovascular treatment of unruptured posterior circulation intracranial aneurysms (UPCIAs is limited in the International Study of Unruptured Intracranial Aneurysms (ISUIA. The aim of this study is to evaluate the periprocedural morbidity, mortality, and midterm clinical and angiographic follow-ups of endovascular treatment of UPCIAs. Materials and Methods: Retrospective analysis of all patients treated in a 2-year period (89 patients: 10-78 years of age, mean: 45.5 ± 14.3/92 UPCIAs. Fifty-eight aneurysms were found incidentally, 12 in association with mass effect symptoms and 22 with stroke. Results: A clinical improvement or stable outcome was achieved in 84 patients (94.4%. The two cases of permanent morbidity included a patient with paralysis and another patient with hemianopia. One patient died after treatment of a giant fusiform vertebrobasilar aneurysm. In one patient, the aneurysm ruptured during treatment, resulting in death. Another patient suffered a fatal aneurysm rupture 4 days after treatment. Giant size (P = 0.005 and mass effect presentation (P = 0.029 were independent predictors of unfavorable outcomes in UPCIAs. Angiographic follow-up was available in 76 of the 86 surviving patients (88.4% with a mean of 6.8 months (range: 1-36 months. Recanalization in six patients (7.9% at 3 months, 4 months, 4 months, 24 months, and 36 months required retreatment in three patients. In-stent stenosis of >50% was found in three patients. Conclusion: Endovascular therapy is an attractive option for UPCIAs with stable midterm outcome. However, the current endovascular option seems to have a limitation for the treatment of the aneurysm with giant size or mass effect presentation.

    Recent reviews on music therapy for people with dementia have been limited to attempting to evaluate whether it is effective, but there is a need for a critical assessment of the literature to provide insight into the possible mechanisms of actions of music therapy. This systematic review uses a narrative synthesis format to determine evidence for effectiveness and provide insight into a model of action. The narrative synthesis framework consists of four elements: (i) theory development; (ii) preliminary synthesis of findings; (iii) exploration of relationships between studies; and (iv) assessment of the robustness of the synthesis. Electronic and hand searches identified 263 potentially relevant studies. Eighteen studies met the full inclusion criteria. Three distinctive strands of investigations emerged: eight studies explored behavioural and psychological aspects, five studies investigated hormonal and physiological changes, and five studies focused on social and relational aspects of music therapy. The musical interventions in the studies were diverse, but singing featured as an important medium for change. Evidence for short-term improvement in mood and reduction in behavioural disturbance was consistent, but there were no high-quality longitudinal studies that demonstrated long-term benefits of music therapy. Future music therapy studies need to define a theoretical model, include better-focused outcome measures, and discuss how the findings may improve the well-being of people with dementia.

    The relationship between attainment of low-density lipoprotein cholesterol (LDL-C) levels and clinical outcomes in patients with peripheral arterial disease (PAD) has received little attention. We sought to investigate clinical outcomes in relation to attainment of LDL-C goals in patients with PAD after endovascular treatment. We reviewed 342 PAD patients treated with endovascular therapy from 2010 through 2012. We categorized patients into two groups based on the attained LDL-C levels at short-term follow-up (mean, 4.8 ± 2.8 months): group A (n = 160), with LDL-C obstructive pulmonary disease (0% vs 7%; P = .001). More patients in group A received statin therapy than those in group B (93% vs 76%; P < .001). MACEs (4% vs 10%; P = .002) and all-cause mortality (2% vs 7%; P = .007) occurred less frequently in group A than in group B at 2 years. A Cox proportional hazards multivariate regression model identified attainment of LDL-C goal <70 mg/dL at short-term follow-up as an independent predictor of reduced MACEs (hazard ratio, 0.25; 95% confidence interval, 0.09-0.67; P = .006) along with age as a predictor of increased MACEs (hazard ratio, 1.04; 95% confidence interval, 1.00-1.08; P = .031). Attainment of LDL-C goal <70 mg/dL at short-term follow-up is an independent predictor of reduced mortality and cardiovascular events after endovascular therapy in patients with PAD.

    Since the relationship between angiogenesis and tumor growth was established by Folkman in 1971, scientists have made efforts exploring the possibilities in treating cancer by targeting angiogenesis. Inhibition of angiogenesis growth factors and administration of angiogenesis inhibitors are the basics of anti-angiogenesis therapy. Transfer of anti-angiogenesis genes has received attention recently not only because of the advancement of recombinant vectors, but also because of the localized and sustained expression of therapeutic gene product inside the tumor after gene transfer. This review provides the up-to-date information about the strategies and the vectors studied in the field of anti-angiogenesis cancer gene therapy. PMID:17109514

    In this study, we evaluated if increase in utilization of endovascular surgery has affected in-hospital mortality rates among patients with acute mesenteric ischemia. The National Inpatient Sample (2003-2011) was queried for acute mesenteric ischemia using ICD-9 code for acute mesenteric ischemia (557.1). This cohort was divided into patients treated with open vascular surgery (open vascular group) and by endovascular therapies (endovascular group) based on the ICD-9CM procedure codes. Multivariable logistic regression was used to determine temporal trend for mortality while adjusting for confounding variables. There was 1.45-fold increase in utilization of endovascular techniques in this study. In-hospital mortality rate, total median charges and length of stay were significantly lower among the endovascular group than the open vascular group despite having significantly higher Elixhauser comorbidities index (3 ± 0.1 vs. 2.7 ± 0.1, p = .003). Over the course of the study period, there was no change in the overall mortality rate despite higher endovascular utilization. Factors associated with increased mortality included age, open surgical repair (Odds ratio: 1.45, 95% Confidence Interval: 1.10-1.91, p = .016) and bowel resection Odds ratio: 2.88, 95% Confidence Interval: 2.01-4.12). The mortality rate for acute mesenteric ischemia remains unchanged throughout this contemporary study. Open surgical intervention, bowel resection and age were associated with increased mortality. Endovascular group patients had better survival despite higher morbidity indices. © The Author(s) 2015.

    2014-08-01

    Acne is prevalent among adolescents and adults with significant psychological effects. Standard oral and topical therapies can have significant side effects including skin irritation, gastrointestinal upset, and the development of drug-resistant bacteria. The use of botanicals and phytochemicals in dermatological products is increasingly popular, and many patients are turning to these alternative therapies for treatment of acne. This study aimed to systematically review clinical studies that have investigated the use of botanical agents in the treatment of acne. PubMed and Embase databases were searched in March 2013 for trials assessing botanical therapies in the treatment of acne vulgaris. Data from these trials are presented, and methodology of each study is assessed. Twenty-three trials met inclusion criteria. Interventions included plant extracts, herbal formulations, and phytochemicals. All studies reported favorable results, and several showed equal or superior treatment to standard therapies. No serious adverse events were reported. Few studies were methodologically rigorous. Each botanical was studied in only one or two trials. Botanicals are promising therapies for acne vulgaris although further research is warranted, especially with regard to severe acne and acne resistant to conventional therapy. There is a need for standardized methods for grading acne and assessing therapeutic effects. Copyright © 2014 John Wiley & Sons, Ltd.

  20. Antimicrobial therapy of acute diarrhoea: a clinical review.

    2016-01-01

    Diarrhoea is one of the most commonly occurring diseases. This article presents a review of the current state of the treatment of acute infectious diarrhoea, as well as of the most important pathogens. The general principles of the therapy of diarrhoea are exemplified, followed by a description of the targeted antimicrobial therapy of the most important bacterial gastrointestinal infections, including salmonellosis, shigellosis and Campylobacter infections, as well as infections with pathogenic Escherichia coli strains, yersiniosis and cholera. Diarrhoea caused by toxigenic Clostridium difficile strains has increased in incidence and in severity. These infections will therefore be described in detail, including important new aspects of treatment. Symptomatic therapy is still the most important component of the treatment of infectious diarrhoea. However, empirical antibiotic therapy should be considered for severely ill patients with a high frequency of stools, fever, bloody diarrhoea, underlying immune deficiency, advanced age or significant comorbidities. Increasing resistance, in particular against fluoroquinolones, must be taken into consideration. Therapy with motility inhibitors is not recommended for Shiga toxin-producing Escherichia coli (STEC) infections, Clostridium difficile infections (CDI), and severe colitis. The macrocyclic antibiotic fidaxomicin can reduce the rate of recurrent disease in CDI. Furthermore, evidence for the benefits of faecal microbiota transplantation as a treatment option for multiple recurrences of CDI is increasing. In conclusion, the treatment of acute diarrhoea is still primarily supportive. General empirical antibiotic therapy for acute diarrhoea is not evidence-based.

    "Political issues" may determine the relative progress if not the ultimate success and acceptance of endovascular surgery as much as its intrinsic merits. These issues include turf battles, commercialization of newly developing technologies, unethical advertising, and self-serving reporting practices in presenting clinical results. Acceptable indications, methods of evaluating results, standardized reporting practices, appropriate "gold standards" for comparison, and controlled trials (without premature release) are recommended, as well as an emphasis on the future need for proper training and credentialing and quality assurance programs.

    Objective: The aim of our retrospective study was to review our single-center experience with aortic abdominal aneurysm (AAA) repair retrospectively. Material and methods: From 1995 to 2005, 70 consecutive patients affected by AAA were treated by endovascular stent-graft repair. Mean follow-up was 23.9 months. Follow-up investigations were performed at 6 and 12 months and yearly thereafter. Five different stent-graft designs were compared to each other. Primary technical success (PTS), assisted primary technical success (APTS), primary clinical success (PCS) and secondary clinical success (SCS) were evaluated. Results: All over PTS was achieved in 94.3%, APTS in 97.1%, PCS in 61.4%, APCS in 64.3% and SCS in 70%. There were 3 type I endoleaks, 25 type II endoleaks, 4 type III endoleaks, 8 limb problems, 5 conversions to open surgery, 10 aneurysm sac expansions and 14 device migrations. Patients with newer generation devices showed better results than patients with first generation prosthesis. In addition results were better for grafts with suprarenal fixation (versus infrarenal fixation) and grafts with barbs and hooks (versus grafts without barbs and hooks). Patients with bad anatomic preconditions showed a higher complication rate. Conclusion: Contrary to first generation products, new stent-graft designs show acceptable technical and clinical results in endovascular AAA aneurysm repair. However, this therapy still should be reserved only for patients with significant comorbities and suitable anatomic conditions

    Objective Endovascular repair (EVAR) of ruptured abdominal aortic aneurysm (rAAA) has become first-line therapy at our institution and is performed under a standardized protocol. We compare perioperative mortality, midterm survival, and morbidity after EVAR and open surgical repair (OSR). Methods Records were retrospectively reviewed from May 2000 to September 2010 for repair of infrarenal rAAAs. Primary end points included perioperative mortality and midterm survival. Secondary end points included acute limb ischemia, length of stay, ventilator-dependent respiratory failure, myocardial infarction, renal failure, abdominal compartment syndrome, and secondary intervention. Statistical analysis was performed using the t-test,X2 test, the Fisher exact test, and logistic regression calculations. Midterm survival was assessed with Kaplan-Meier analysis and Cox proportional hazard models. Results Seventy-four infrarenal rAAAs were repaired, 19 by EVAR and 55 by OSR. Despite increased age and comorbidity in the EVAR patients, perioperative mortality was 15.7% for EVAR, which was significantly lower than the 49% for OSR (odds ratio, 0.19; 95% CI, 0.05-0.74; P = .008). Midterm survival also favored EVAR (hazard ratio, 0.40; 95% CI, 0.21-0.77; P = .028, adjusted for age and sex). Mean follow-up was 20 months, and 1-year survival was 60% for EVAR vs 45% for OSR. Mean length of stay for patients surviving >1 day was 10 days for EVAR and 21 days for OSR (P = .004). Ventilator-dependent respiratory failure was 5% in the EVAR group vs 42% for OSR (odds ratio, 0.08; 95% CI, 0.01-0.62; P = .001). Conclusions EVAR of rAAA has a superior perioperative survival advantage and decreased morbidity vs OSR. Although not statistically significant, overall survival favors EVAR. We recommend that EVAR be considered as the first-line treatment of rAAAs and practiced as the standard of care. PMID:22626871

    Full Text Available The incidence of Alzheimers disease increases with advancing age. This increase cause significant economic and emotional burden on family and national health care system which makes Alzheimers disease a national issue to be considered. Music therapy could be an alternative treatment approach in Alzheimer's disease. Especially in the second stage of Alzheimers disease, growth and expansion of amyloid plaques results in anger and aggression among patients. Calming effects of music might be beneficial in management of patients during this period. This study is a systematic review of researches conducted to determine the effects of music therapy in Alzheimer's diseases. In sum results have supported possible positive effects of music therapy on Alzheimer patients. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2016; 8(3.000: 266-274

  11. Efficacy of light therapy for perinatal depression: a review

    2012-06-01

    Full Text Available Abstract Perinatal depression is an important public health problem affecting 10% to 20% of childbearing women. Perinatal depression is associated with significant morbidity, and has enormous consequences for the wellbeing of the mother and child. During the perinatal period, treatment of depression, which could affect the mother and child during pregnancy and lactation, poses a complex problem for both mother and clinician. Bright light therapy may be an attractive treatment for perinatal depression because it is low cost, home-based, and has a much lower side effect profile than pharmacotherapy. The antidepressant effects of bright light are well established, and there are several rationales for expecting that bright light might also be efficacious for perinatal depression. This review describes these rationales, summarizes the available evidence on the efficacy of bright light therapy for perinatal depression, and discusses future directions for investigation of bright light therapy as a treatment for perinatal depression.

    Botanical and cosmeceutical therapies are commonly used to treat symptoms of rosacea such as facial erythema, papules/pustule counts, and telangiectasia. These products may contain plant extracts, phytochemicals, and herbal formulations. The objective of this study was to review clinical studies evaluating the use of botanical agents for the treatment of rosacea. MEDLINE and Embase databases were searched for clinical studies evaluating botanical therapies for rosacea. Major results were summarized, and study methodology was analyzed. Several botanical therapies may be promising for rosacea symptoms, but few studies are methodologically rigorous. Several plant extract and phytochemicals effectively improved facial erythema and papule/pustule counts caused by rosacea. Many studies are not methodologically rigorous. Further research is critical, as many botanicals have been evaluated in only one study. Botanical agents may reduce facial erythema and effectively improve papule/pustule counts associated with rosacea. Although promising, further research in the area is imperative.

    2017-02-01

    Dementia affects more than 47.5 million people worldwide, and the number is expected to continue to increase as the population ages. Doll therapy is an emerging nonpharmacologic management strategy for patients with advanced dementia, especially in patients with challenging behaviours. A total of 12 published studies (mainly cohort and observational studies) were identified and discussed in this systematic review. In most instances, cognitive, behavioural and emotional symptoms were alleviated and overall wellbeing was improved with doll therapy, and dementia sufferers were found to be able to better relate with their external environment. Despite the relative paucity of empirical data and ethical concerns, we are of the opinion that doll therapy is effective for dementia care, is well-aligned with the ethos of person-centred care and should be applied in the management of dementia patients. Future research should include more robust randomized controlled trials. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Statin therapy is considered critical both in primary and secondary prevention of cardiovascular disease in diabetes. Cholesterol Treatment Trialists' Collaborators meta-analysis of 14 randomised trials of statins in 18686 people with diabetes provides the latest and largest evidence showing a significant 21% reduction in major vascular events per mmol/l reduction in LDL cholesterol. Importantly, the risk reduction was similar in both types of diabetes. Growing evidence supports the view that statin therapy reduces microvascular complications as well.

    Aneurysms of the posterior cerebral artery (PCA) are rare, and most of the studies reported in the literature in which the endovascular approach was applied were carried out on a limited number of patients with PCA aneurysms. We retrospectively reviewed our cases of PCA aneurysms - at various locations and of differing shapes - that received endovascular treatment and evaluated the treatment outcome. From January 1996 to December 2006, 13 patients (eight females and five males) with 17 PCA aneurysms (nine fusiform and eight saccular) were treated using the endovascular approach. The age of the patients ranged from 20 to 67 years, with a mean age of 44 years. Of the 13 patients, ten presented with intracranial hemorrhage, and one patient, with a large P2 aneurysm, presented with trigeminal neuralgia; the aneurysms were asymptomatic in the remaining two patients. All 13 patients were successfully treated, with only one procedure-related symptomatic complication. Seven patients were treated by occlusion of the aneurysm and parent artery together; five patients, by selective embolization of the aneurysm; one patient, by partial coiling. Although infarctions were found in two patients treated with selective embolization and in three patients treated with parent artery occlusion, only one patient with a ruptured P2 aneurysm treated with parent artery occlusion developed transient amnesia as an ischemic symptom. Posterior cerebral artery aneurysms can be treated safely with either occlusion of the aneurysm together with the PCA or with a selective coil embolization. Infarctions may occur after endovascular treatment, but they are rarely the cause of a disabling symptom. (orig.)

  16. Review of Tumor Dormancy Therapy Using Traditional Oriental Herbal Medicine

    2013-03-01

    Full Text Available Objective: Standard cancer therapy prolongs survival, but can be detrimental to the quality of life, compromise the immune system, and leave residual disease that can cause recurrence years or decades in the future. Tumor dormancy therapy is a novel therapeutic approach that may improve these shortcomings, promote quality of life, and prolong survival. The aim of this study was to analyze studies on dormancy therapy, especially studies using traditional Oriental herbal medicine, so as to evaluate the efficacy of dormancy therapy with traditional oriental herbal medicine. Methods: We conducted a systematic literature review using Scientific and Technical Information Integration Services (NDSL, PubMed, and RISS. We searched for clinical reports, papers, and books related to tumor metastasis, recurrence, immunotherapy, tumor dormancy, and traditional oriental herbal medicine with anticancer effects. Seventy-nine (79 experimental and clinical articles in both Korean and English were reviewed. This study was conducted from March 1, 2012 to May 31, 2012. Results: This approach, Tumor dormancy therapy, rather than seeking to remove the tumor, includes combination of low-dose chemotherapy, immunotherapy, immunosurveillance, and other methods to stabilize tumor growth and to enhance the host is immunity against disseminated tumor cells and thus to manage cancer as a chronic disease while maintaining quality of life. In particular, integrative use of Oriental herbal medicine has been shown to induce or maintain tumor dormancy, increase the effectiveness of conventional chemotherapy, improve quality of life, and prolong survival. Conclusion: Tumor dormancy therapy is a promising novel therapeutic approach that may be especially effective with Oriental herbal medicine. Further research is needed to determine its potential mechanisms and therapeutic applications.

    Standard cancer therapy prolongs survival, but can be detrimental to the quality of life, compromise the immune system, and leave residual disease that can cause recurrence years or decades in the future. Tumor dormancy therapy is a novel therapeutic approach that may improve these shortcomings, promote quality of life, and prolong survival. The aim of this study was to analyze studies on dormancy therapy, especially studies using traditional Oriental herbal medicine, so as to evaluate the efficacy of dormancy therapy with traditional oriental herbal medicine. We conducted a systematic literature review using Scientific and Technical Information Integration Services (NDSL), PubMed, and RISS. We searched for clinical reports, papers, and books related to tumor metastasis, recurrence, immunotherapy, tumor dormancy, and traditional oriental herbal medicine with anticancer effects. Seventy-nine (79) experimental and clinical articles in both Korean and English were reviewed. This study was conducted from March 1, 2012 to May 31, 2012. This approach, Tumor dormancy therapy, rather than seeking to remove the tumor, includes combination of low-dose chemotherapy, immunotherapy, immunosurveillance, and other methods to stabilize tumor growth and to enhance the host is immunity against disseminated tumor cells and thus to manage cancer as a chronic disease while maintaining quality of life. In particular, integrative use of Oriental herbal medicine has been shown to induce or maintain tumor dormancy, increase the effectiveness of conventional chemotherapy, improve quality of life, and prolong survival. Tumor dormancy therapy is a promising novel therapeutic approach that may be especially effective with Oriental herbal medicine. Further research is needed to determine its potential mechanisms and therapeutic applications.

    Reiki touch therapy is a complementary biofield energy therapy that involves the use of hands to help strengthen the body's ability to heal. There is growing interest among nurses to use Reiki in patient care and as a self-care treatment, however, with little supportive empirical research and evidence to substantiate these practices. The purpose of this integrative review is to begin the systematic process of evaluating the findings of published Reiki research. Selected investigations using Reiki for effects on stress, relaxation, depression, pain, and wound healing management, among others is reviewed and summarized. A summary of Reiki studies table illustrates the study descriptions and Reiki treatment protocols specified in the investigations. Synthesis of findings for clinical practice and implications for future research are explored.

    2009-03-01

    This systematic review explores the effects of dysphagia treatment for Parkinson's disease. The review includes rehabilitative, surgical, pharmacologic, and other treatments. Only oropharyngeal dysphagia is selected for this literature search, excluding dysphagia due to esophageal or gastric disorders. The effects of deep brain stimulation on dysphagia are not included. In general, the literature concerning dysphagia treatment in Parkinson's disease is rather limited. Most effect studies show diverse methodologic problems. Multiple case studies and trials are identified by searching biomedical literature databases PubMed and Embase, and by hand-searching reference lists. The conclusions of most studies cannot be compared with one another because of heterogeneous therapy methods and outcome measures. Further research based on randomized controlled trials to determine the effectiveness of different therapies for dysphagia in Parkinson's disease is required.

    To summarize and critically appraise the available evidence on exercise therapy and other types of physical therapies for patients with neuromuscular diseases (NMD). Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews, Medline, CINAHL, EMBASE (Rehabilitation and Physical Medicine), and reference lists of reviews and articles. Randomized clinical trials (RCTs), controlled clinical trials (CCTs), and other designs were included. Study participants had to have any of the following types of NMD: motoneuron diseases, disorders of the motor nerve roots or peripheral nerves, neuromuscular transmission disorders, or muscle diseases. All types of exercise therapy and other physical therapy modalities were included. Outcome measures had to be at the level of body functions, activities, or participation according to the definitions of the International Classification of Functioning, Disability and Health (ICF). Two reviewers independently decided on inclusion or exclusion of articles and rated the methodologic quality of the studies included. All RCTs, CCTs, and other designs only if of sufficient methodologic quality were included in a best evidence synthesis. A level of evidence was attributed for each subgroup of NMD and each type of intervention. Initially 58 studies were included: 12 RCTs, 5 CCTs, and 41 other designs. After methodologic assessment, 19 other designs were excluded from further analysis. There is level II evidence ("likely to be effective") for strengthening exercises in combination with aerobic exercises for patients with muscle disorders. Level III evidence ("indications of effectiveness") was found for aerobic exercises in patients with muscle disorders and for the combination of muscle strengthening and aerobic exercises in a heterogeneous group of muscle disorders. Finally, there is level III evidence for breathing exercises for patients with myasthenia gravis and for patients with myotonic muscular dystrophy

    The standard treatment for aortic aneurysms is surgical replacement with a prosthetic graft. Currently there is great interest in endoluminal intervention for treatment of aortic aneurysm. The purpose of this study was to evaluate the safety and effectiveness of endoluminally placed Stent-graft for the treatment of aortic aneurysms. Transluminal endovascular Stent-graft placements were attempted in 9 patients with infra-renal aortic aneurysms(n 6), thoracic aortic aneurysm(n = 1), and aortic dissection(n = 2). The endovascular Stent-grafts were custom-designed for each patient and were constructed of self-expandable modified Gianturco Stents covered with polytetrafluroethylene. The Stent-grafts were introduced through a 16-18 French sheath and expanded to 17-30 mm in diameter. The endovascular therapy was performed using a common femoral artery cutdown with local anesthesia. The endovascular Stent-graft deployment was achieved in 7 of 9 patients. Two cases failed deployment of the Stent-graft due to iliac artery stenosis and tortousity. There were complete thrombosis of the thoracic and infra-renal aortic aneurysm surround the Stent-graft in 3 patients, and persistent leak with partial thrombosis in 2. Two patients with aortic dissection were successfully treated by obliteration of entry tears. There were no major complication associated with Stent-graft placement. These preliminary results show that transluminal endovascular Stent-grafts offer great promise and good results. Further investigation is needed to establish its long-term safety and efficacy

    Ruptured cerebral arterial aneurysms require prompt treatment by either surgical clipping or endovascular coiling. Training for these sophisticated endovascular procedures is essential and ideally performed in animals before their use in humans. Simulators and established animal models have shown drawbacks with respect to degree of reality, size of the animal model and aneurysm, or time and effort needed for aneurysm creation. We therefore aimed to establish a realistic and readily available aneurysm model. Five anticoagulated domestic pigs underwent endovascular intervention through right femoral access. A total of 12 broad-neck aneurysms were created in the carotid, subclavian, and renal arteries using the Amplatzer vascular plug. With dedicated vessel selection, cubic, tubular, and side-branch aneurysms could be created. Three of the 12 implanted occluders, two of them implanted over a side branch of the main vessel, did not induce complete vessel occlusion. However, all aneurysms remained free of intraluminal thrombus formation and were available for embolization training during a surveillance period of 6 h. Two aneurysms underwent successful exemplary treatment: one was stent-assisted, and one was performed with conventional endovascular coil embolization. The new porcine aneurysm model proved to be a straightforward approach that offers a wide range of training and scientific applications that might help further improve endovascular coil embolization therapy in patients with cerebral aneurysms.

    Schema Therapy is becoming an increasingly popular psychological model for working with individuals who have a variety of mental health and personality difficulties. The aim of this review is to look at the current evidence base for Schema Therapy and highlight directions for further research. A systematic search of the literature was conducted up until January 2011. All studies that had clinically tested the efficacy of Schema Therapy as described by Jeffrey Young (1994 and 2003) were considered. These studies underwent detailed quality assessments based on Scottish Intercollegiate Guidelines Network (SIGN-50) culminating in 12 studies being included in the review. The culminative message (both from the popularity of this model and the medium-to-large effect sizes) is of a theory that has already demonstrated clinically effective outcomes in a small number of studies and that would benefit from ongoing research and development with complex client groups. It is imperative that psychological practice be guided by high-quality research that demonstrates efficacious, evidence-based interventions. It is therefore recommended that researchers and clinicians working with Schema Therapy seek to build on these positive outcomes and further demonstrate the clinical effectiveness of this model through ongoing research.

    Full Text Available Percutaneous vascular embolization plays an important role in the management of various gynecologic and obstetric abnormalities. Transcatheter embolization is a minimally invasive alternative procedure to surgery with reduced morbidity and mortality, and preserves the patient's future fertility potential. The clinical indications for transcatheter embolization are much broader and include many benign gynecologic conditions, such as fibroid, adenomyosis, and arteriovenous malformations (AVMs, as well as intractable bleeding due to inoperable advanced-stage malignancies. The most well-known and well-studied indication is uterine fibroid embolization. Uterine artery embolization (UAE may be performed to prevent or treat bleeding associated with various obstetric conditions, including postpartum hemorrhage (PPH, placental implantation abnormality, and ectopic pregnancy. Embolization of the uterine artery or the internal iliac artery also may be performed to control pelvic bleeding due to coagulopathy or iatrogenic injury. This article discusses these gynecologic and obstetric indications for transcatheter embolization and reviews procedural techniques and outcomes.

    Should a tooth with pulpal involvement be saved through endodontic therapy, or extracted and replaced with a single tooth implant? Within the limitations of the existing literature, this systematic review of treatment outcomes found that initial endodontic treatment had a high long-term survival rate, equivalent to replacement of a missing tooth with an implant-supported restoration. Single tooth implants should be considered as the first treatment option for patients requiring extraction and tooth replacement.

    2013-01-01

    Background Considered as a moment of psychological vulnerability, adolescence is remarkably a risky period for the development of psychopathologies, when the choice of the correct therapeutic approach is crucial for achieving remission. One of the researched therapies in this case is electroconvulsive therapy (ECT). The present study reviews the recent and classical aspects regarding ECT use in adolescents. Methods Systematic review, performed in November 2012, conformed to the PRISMA statement. Results From the 212 retrieved articles, only 39 were included in the final sample. The reviewed studies bring indications of ECT use in adolescents, evaluate the efficiency of this therapy regarding remission, and explore the potential risks and complications of the procedure. Conclusions ECT use in adolescents is considered a highly efficient option for treating several psychiatric disorders, achieving high remission rates, and presenting few and relatively benign adverse effects. Risks can be mitigated by the correct use of the technique and are considered minimal when compared to the efficiency of ECT in treating psychopathologies. PMID:23718899

    Objective: To setup an endovascular treatment of intracranial aneurysm with detachable balloon and micro-coil. Methods: Trans-femoral artery Seldinger's catheterization was used. Balloons and free MDS, GDC micro-coils were pushed into the aneurysm or carrying arteries. Results: No mortality occurred in authors' group. Internal carotid arteries (ICA) were occluded with detachable balloons in 5 aneurysms at sinus segment of ICA and 4 traumatic pseudo-aneurysms. No complications occurred. 9 aneurysms were completely occluded with micro-coils and 2 were partly (95%) occluded. 2 patients got mild paralysis due to vasospasm or mal detaching of MDS coils. Conclusions: Balloon occlusion of ICA for treatment of aneurysm at sinus segment is safe and effective in case of having abundant collateral circulation. Coil occlusion of intracranial aneurysm is a promising method of endovascular treatment. Compared with MDS, GDC coil is safer but expensive. Free coil is not very safe theoretically, but can be used with careful consideration as it is much cheaper

    Endovascular interventions for intracranial aneurysms have evolved substantially over the past several decades. A citation rank list is used to measure the scientific and/or clinical impact of an article. Our objective was to identify and analyze the characteristics of the 100 most cited articles in the field of endovascular therapy for intracranial aneurysms. We performed a retrospective bibliometric analysis between July and August 2017. Articles were searched on the Science Citation Index Expanded database using Web of Science in order to identify the most cited articles in the endovascular therapy of intracranial aneurysms since 1945. Using selected key terms ('intracranial aneurysm', 'aneurysm', 'aneurysmal subarachnoid', 'endovascular', 'coiling', 'stent-assisted', 'balloon-assisted', 'flow-diversion') yielded a total of 16 314 articles. The top 100 articles were identified and analyzed to extract relevant information, including citation count, authorship, article type, subject matter, institution, country of origin, and year of publication. Citations for the top 100 articles ranged from 133 to 1832. All articles were cited an average of 27 times per year. There were 45 prospective studies, including 7 level-II randomized controlled trials. Most articles were published in the 2000s (n=53), and the majority constituted level III or level IV evidence. Half of the top 100 articles arose from the USA. This study provides a comprehensive overview of the most cited articles in the endovascular management of intracranial aneurysms. It recognizes the contributions made by key authors and institutions, providing an important framework to an enhanced understanding of the evidence behind the endovascular treatment of aneurysms. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Beneciuk, Jason M; Bishop, Mark D; George, Steven Z

    2009-01-01

    Background and Purpose: Clinical prediction rules (CPRs) involving physical therapy interventions have been published recently. The quality of the studies used to develop the CPRs was not previously considered, a fact that has potential implications for clinical applications and future research. The purpose of this systematic review was to determine the quality of published CPRs developed for physical therapy interventions. Methods: Relevant databases were searched up to June 2008. Studies were included in this review if the explicit purpose was to develop a CPR for conditions commonly treated by physical therapists. Validated CPRs were excluded from this review. Study quality was independently determined by 3 reviewers using standard 18-item criteria for assessing the methodological quality of prognostic studies. Percentage of agreement was calculated for each criterion, and the intraclass correlation coefficient (ICC) was determined for overall quality scores. Results: Ten studies met the inclusion criteria and were included in this review. Percentage of agreement for individual criteria ranged from 90% to 100%, and the ICC for the overall quality score was .73 (95% confidence interval=.27–.92). Criteria commonly not met were adequate description of inclusion or exclusion criteria, inclusion of an inception cohort, adequate follow-up, masked assessments, sufficient sample sizes, and assessments of potential psychosocial factors. Quality scores for individual studies ranged from 48.2% to 74.0%. Discussion and Conclusion: Validation studies are rarely reported in the literature; therefore, CPRs derived from high-quality studies may have the best potential for use in clinical settings. Investigators planning future studies of physical therapy CPRs should consider including inception cohorts, using longer follow-up times, performing masked assessments, recruiting larger sample sizes, and incorporating psychological and psychosocial assessments.

    We report our experience with the endovascular treatment of the vertebral artery origin in patients presenting with symptomatic vertebrobasilar ischemia and compare our results with those reported in the literature. In 25 patients, 28 procedures were performed. Patients presented with posterior circulation ischemic symptoms despite optimal medical therapy with antiplatelet drugs and had a digital subtraction angiogram demonstrating stenosis of the origin of the vertebral artery greater than 50%. Retrospective review of the medical records, clinical notes and radiologic-procedural reports was performed. Of the 25 patients, 18 were male and 7 female. Their ages ranged from 50 to 84 years. In 23 of the 25 patients the contralateral vertebral artery was occluded, hypoplastic, absent, or had greater than 50% stenosis. In 13 of the 25 patients angiographic evidence of significant anterior circulation disease was demonstrated. In 18 of the 25 patients the left vertebral artery was affected. The mean stenosis was 82.6%. Follow-up records were available in 19 patients. The mean follow-up was 24 months. Five of the 19 patients had recurrent symptoms of vertebrobasilar ischemia and three patients were retreated. Of the 28 procedures performed, 23 were angioplasty/stenting and 5 were angioplasties alone. Overall technical success was achieved in 26 of the 28 procedures (92.8%). No procedure-related transient ischemic attack, stroke or death was noted. Endovascular treatment of the vertebral artery origin in this patient population is feasible, safe, and effective. There are some questions regarding the long-term follow-up and rate of restenosis and clinical recurrences that are yet to be answered. (orig.)

    Endovascular vein harvest (EDVH) requires CO(2) insufflation to expand the subcutaneous space, allowing visualization and dissection of the saphenous vein. The purpose of this study was to assess the extent of CO(2) absorption during EDVH. Prospective observational study. Single tertiary care hospital. Sixty patients (30 EDVH and 30 open-vein harvest) undergoing isolated coronary artery bypass graft surgery. Hemodynamic, procedural, and laboratory data were collected prior to (baseline), during, and at it the conclusion (final) of vein harvesting. Data were also collected during cardiopulmonary bypass (CPB). Data were compared by using t tests, analysis of variance, and correlation statistics when needed. There were significant increases in arterial CO(2) (PaCO(2), 35%) and decreases in pH (1.35%) during EDVH. These were associated with increases in heart rate, mean blood pressure, and cardiac output. Within the EDVH group, greater elevations (>10 mmHg) in PaCO2 were more likely during difficult harvest procedures, and these patients exhibited greater increase in heart rate. Elevated CO(2) persisted during CPB, requiring higher systemic gas flows and greater use of phenylephrine to maintain desired hemodynamics. EDVH was associated with systemic absorption of CO(2). Greater absorption was more likely in difficult procedures and was associated with greater hemodynamic changes requiring medical therapy.

    Full Text Available Peripheral artery disease (PAD is one of the major vascular complications in individuals suffering from diabetes and in the elderly that can progress to critical limb ischemia (CLI, portending significant burden in terms of patient morbidity and mortality. Over the last two decades, stem cell therapy (SCT has risen as an attractive alternative to traditional surgical and/or endovascular revascularization to treat this disorder. The primary benefit of SCT is to induce therapeutic neovascularization and promote collateral vessel formation to increase blood flow in the ischemic limb and soft tissue. Existing evidence provides a solid rationale for ongoing in-depth studies aimed at advancing current SCT that may change the way PAD/CLI patients are treated.

    To review pediatric physical therapy experiences described in the literature and to analyze the production of knowledge on physical therapy in the context of pediatric primary health care (PPHC). A systematic review was conducted according to the PRISMA criteria. The following databases were searched: MEDLINE, LILACS, SciELO, PubMed, Scopus and Cochrane; Brazilian Ministry of Health's CAPES doctoral dissertations database; and System for Information on Grey Literature in Europe (SIGLE). The following search terms were used: ["primary health care" and ("physical therapy" or "physiotherapy") and ("child" or "infant")] and equivalent terms in Portuguese and Spanish, with no restriction on publication year. Thirteen articles from six countries were analyzed and grouped into three main themes: professional dilemmas (three articles), specific competencies and skills required in a PPHC setting (seven articles), and practice reports (four articles). Professional dilemmas involved expanding the role of physical therapists to encompass community environments and sharing the decision-making process with the family, as well as collaborative work with other health services to identify the needs of children. The competencies and skills mentioned in the literature related to the identification of clinical and sociocultural symptoms that go beyond musculoskeletal conditions, the establishment of early physical therapy diagnoses, prevention of overmedication, and the ability to work as team players. Practice reports addressed stimulation in children with neurological diseases, respiratory treatment, and establishing groups with mothers of children with these conditions. The small number of studies identified in this review suggests that there is little knowledge regarding the roles of physical therapists in PPHC and possibly regarding the professional abilities required in this setting. Therefore, further studies are required to provide data on the field, along with a continuing

    Surgical therapies for treatment-refractory obsessive-compulsive disorder (OCD), such as deep brain stimulation or psychosurgery, remain unattainable for many patients. Despite the long-held view that electroconvulsive therapy (ECT) is an ineffective treatment for OCD, there is no systematic review to support or refute this claim, which is the basis of the current review. A systematic search of MEDLINE, Web of Science, Scopus, and LILACS databases was conducted on December 22, 2013, using the terms obsessive-compulsive disorder and electroconvulsive therapy. Reference lists, specific journals, and clinical trial registries were also scrutinized. No date or language limitation was imposed on the search. After irrelevant and redundant records from the 500 identified titles were excluded, the 50 articles reporting the acute treatment effects of ECT in OCD and related constructs (involving a total of 279 patients) were analyzed for this study. The relevant sociodemographic, clinical, and outcome data of individual cases were extracted. Data from individual cases were used to compare the characteristics of responders versus nonresponders to ECT. Most selected records were case reports/series; there were no randomized controlled trials. A positive response was reported in 60.4% of the 265 cases in which individual responses to ECT were available. ECT responders exhibited a significantly later onset of OCD symptoms (P = .003), were more frequently nondepressed (P = .009), more commonly reported being treated with ECT for severe OCD (P = .01), and received a fewer number of ECT sessions (P = .03). ECT responders were also less frequently previously treated with adequate trials of serotonin reuptake inhibitors (P = .05) and cognitive-behavioral therapy (P = .005). Although 60% of the reported cases reviewed exhibited some form of a positive response to ECT, it cannot be stated that this provides evidence that ECT is indeed effective for OCD. © Copyright 2015 Physicians

    2008-05-01

    Photodynamic therapy (PDT) uses light-activated drugs to treat diseases ranging from cancer to age-related macular degeneration and antibiotic-resistant infections. This paper reviews the current status of PDT with an emphasis on the contributions of physics, biophysics and technology, and the challenges remaining in the optimization and adoption of this treatment modality. A theme of the review is the complexity of PDT dosimetry due to the dynamic nature of the three essential components—light, photosensitizer and oxygen. Considerable progress has been made in understanding the problem and in developing instruments to measure all three, so that optimization of individual PDT treatments is becoming a feasible target. The final section of the review introduces some new frontiers of research including low dose rate (metronomic) PDT, two-photon PDT, activatable PDT molecular beacons and nanoparticle-based PDT.

    Ning Ma

    Full Text Available OBJECTIVES: To evaluate the safety of low-dose aspirin plus clopidogrel versus high-dose aspirin plus clopidogrel in prevention of vascular risk within 90 days of duration of dual antiplatelet therapy in patients treated with intracranial endovascular treatment. METHODS: From January 2012 to December 2013, this prospective and observational study enrolled 370 patients with symptomatic intracranial atherosclerotic stenosis of ≥70% with poor collateral undergoing intracranial endovascular treatment. Antiplatelet therapy consists of aspirin, at a low-dose of 100 mg or high-dose of 300 mg daily; clopidogrel, at a dose of 75 mg daily for 5 days before endovascular treatment. The dual antiplatelet therapy continued for 90 days after intervention. The study endpoints include acute thrombosis, subacute thrombosis, stroke or death within 90 days after intervention. RESULTS: Two hundred and seventy three patients received low-dose aspirin plus clopidogrel and 97 patients received high-dose aspirin plus clopidogrel before intracranial endovascular treatment. Within 90 days after intervention, there were 4 patients (1.5% with acute thrombosis, 5 patients (1.8% with subacute thrombosis, 17 patients (6.2% with stroke, and 2 death (0.7% in low-dose aspirin group, compared with no patient (0% with acute thrombosis, 2 patient (2.1% with subacute thrombosis, 6 patients (6.2% with stroke, and 2 death (2.1% in high-dose aspirin group, and there were no significant difference in all study endpoints between two groups. CONCLUSION: Low-dose aspirin plus clopidogrel is comparative in safety with high-dose aspirin plus clopidogrel within 90 days of duration of dual antiplatelet therapy in patients treated with intracranial endovascular treatment.

    2010-04-01

    The purpose of this systematic review was to investigate if the use of magnification devices in endodontics is associated with the improvement of clinical and radiographic outcomes. The treatment success as determined by clinical and radiographic evaluation after 1-year follow-up was the main outcome. The main search terms used alone or in combination were: endodontic treatment, endodontic therapy, endodontic surgery, apicoectomy, periapical surgery, microscope, endoscope, loupes, magnification devices. The authors searched MEDLINE, Embase, Cochrane Oral Health Specialized Register, Cochrane Central Register of Controlled Trials for articles published up to September 2009 plus hand-searching of relevant journals and reference list of pertinent reviews and included studies. Prospective clinical trials comparing endodontic therapy performed with or without using magnification devices, as well as trials comparing two or more magnification devices for endodontic therapy were considered. Three prospective studies were included, all dealing with endodontic surgery. No significant difference in outcomes was found among patients treated using magnifying loupes, surgical microscope or endoscope. Similarly, no difference was found with or without using the endoscope. No comparative study on magnification devices was found regarding orthograde endodontic treatment. The type of magnification device per se can only minimally affect the treatment outcome. Well-designed randomized trials should be performed to determine the true difference in treatment outcomes when using a magnification device in both orthograde and surgical endodontic treatment, if any exist.

    2007-09-01

    Stem cells carry the promise to cure a broad range of diseases and injuries, from diabetes, heart and muscular diseases, to neurological diseases, disorders and injuries. Significant progresses have been made in stem cell research over the past decade; the derivation of embryonic stem cells (ESCs) from human tissues, the development of cloning technology by somatic cell nuclear transfer (SCNT) and the confirmation that neurogenesis occurs in the adult mammalian brain and that neural stem cells (NSCs) reside in the adult central nervous system (CNS), including that of humans. Despite these advances, there may be decades before stem cell research will translate into therapy. Stem cell research is also subject to ethical and political debates, controversies and legislation, which slow its progress. Cell engineering has proven successful in bringing genetic research to therapy. In this review, I will review, in two examples, how investigators are applying cell engineering to stem cell biology to circumvent stem cells' ethical and political constraints and bolster stem cell research and therapy.

    Duchenne muscular dystrophy (DMD) is a lethal progressive pediatric muscle disorder and genetically inherited as an X-linked disease that caused by mutations in the dystrophin gene. DMD leads to progressive muscle weakness, degeneration, and wasting; finally, follows with the premature demise in affected individuals due to respiratory and/or cardiac failure typically by age of 30. For decades, scientists tried massively to find an effective therapy method, but there is no absolute cure currently for patients with DMD, nevertheless, recent advanced progressions on the treatment of DMD will be hopeful in the future. Several promising gene therapies are currently under investigation. These include gene replacement, exon skipping, suppression of stop codons. More recently, a promising gene editing tool referred to as CRISPR/Cas9 offers exciting perspectives for restoring dystrophin expression in patients with DMD. This review intents to briefly describe these methods and comment on their advances. Since DMD is a genetic disorder, it should be treated by replacing the deficient DMD copy with a functional one. However, there are different types of mutations in this gene, so such therapeutic approaches are highly mutation specific and thus are personalized. Therefore, DMD has arisen as a model of genetic disorder for understanding and overcoming of the challenges of developing personalized genetic medicines, consequently, the lessons learned from these approaches will be applicable to many other disorders. This review provides an update on the recent gene therapies for DMD that aim to compensate for dystrophin deficiency and the related clinical trials.

  8. Endovascular stent grafting of thoracic aortic aneurysms: technological advancements provide an alternative to traditional surgical repair.

    Jones, Lauren E Beste

    2005-01-01

    The use of endovascular stent grafts is a leading technological advancement in the treatment of thoracic aortic aneurysms, and is being trialed in the United States as an alternative to medical management and traditional surgical repair. Aortic stent grafts, initially used only for abdominal aortic aneurysms, have been used for over 10 years in Europe and are currently under United States Food and Drug Administration investigation for the treatment of chronic and acute aortic aneurysms. Diseases of the thoracic aorta are often present in high-risk individuals, and, as a result, there is a high morbidity and mortality rate associated with both medical and surgical management of these patients. The development and refinement of endovascular approaches have the potential to decrease the need for traditional surgical repair, especially in high-risk populations such as the elderly and those with multiple comorbidities. Endovascular technology for thoracic repair has only been used in Europe for the last 10 years, with no long-term outcomes available; however, preliminary research demonstrates favorable early and midterm outcomes showing that endovascular stent graft placement to exclude the dilated, dissected, or ruptured aorta is both technically feasible and safe for patients. The article highlights the historical perspective of endovascular stent grafting as well as a description of patient selection, the operative procedure, benefits, risks, and unresolved issues pertaining to the procedure. A brief review of aneurysm and dissection pathophysiology and management is provided, as well as postoperative management for acute care nurses and recommendations for clinical practice.

  9. Oral surgery in patients under antithrombotic therapy. Narrative review.

    2015-02-01

    Full Text Available Population aging and the increasing rates of cardiovascular diseases have raised the number of patients receiving antithrombotic therapy in elective or emergency dental care, including surgical procedures. The aim of this article is to review the evidence and clinical guidelines for management of patients on antithrombotic therapy published in the past five years. The American Antithrombotic Therapy Guideline - 2012 - generally recommends not to suspend antiplatelet or anticoagulant treatment in dental procedures since they are considered to have low bleeding risk and easy resolution. In the dental field, there is ample published evidence regarding oral surgical procedure management, especially by maxillofacial surgeons, showing a low number of complications associated with extractions or other minor oral surgical procedures without suspending antithrombotic drugs and only taking some minimum safeguards, such as healing by first intention or the use of some local hemostatic agents. In general, patients under chronic antithrombotic therapy should keep their medication when undergoing low and medium complexity dental procedures, since complications are minor and easy to handle. Due to interactions between them, particular care should be taken with patients using more than one drug.

    2017-12-01

    Massage therapy is becoming increasingly popular in human and animal physiotherapy and rehabilitation. Wider application of the technique led to research efforts aimed at providing scientific support to anecdotal beneficial effects, particularly pain relief. Recent studies have shown that massage therapy alters dopamine and serotonin levels, decreases noradrenaline levels, and modulates the immune system. Psychological effects such as reduction of stress and anxiety, with improvement of depressive patients, have been reported in humans. This article set out to review the major aspects of massage therapy based on recent publications on the topic, and to extrapolate concepts and practical aspects described in human physiotherapy to the veterinary patient, particularly the applicability of different techniques in Small Animal Medicine. Indications of massage therapy in small animals include pain relief, orthopedic rehabilitation, Canine Sports Medicine, intensive care, and management of nonspecific edema. Techniques described in this article were originally intended for use in humans and scientific data supporting anecdotal, beneficial effects in domestic animals are still lacking; this fruitful area for research is therefore open to veterinary professionals.

    2015-03-01

    Full Text Available The present study aims at identifying how the everyday life concept is used in the Occupational Therapy field in the English language literature and at making considerations in relation to the Brazilian literature on the subject. A systematic review of the international literature on the everyday life concept in the Occupational Therapy field was carried out and, from the results of this phase, reflections about the differences and similarities noticed in the use of this concept in the field of occupational therapy in Brazil are presented. Twenty articles selected from the CAPES (Coordination for the Improvement of Higher Education Personnel database were elected for analysis. This analysis found that English speaking authors, on the issue of everyday life rupture, focus on the assistance needed to help individuals to be able to perform their former occupations in an autonomous way. Besides, the way people live their everyday lives is an element that constitutes the person’s identity; people become what they are from their occupations. Everyday life is described in occupational terms; it is understood by the meaningful things people do in their lives. It is pointed out that, as opposed to the national literature, the international literature does not focus on the connection between everyday life and the social-political-cultural context. Thus, we discuss that the understanding about the contextualized everyday life is shared with Brazilian occupational therapists, and it has the potential to be presented as a construct on which the Brazilian contemporary occupational therapy identity is built.

    There is limited guidance available to clinicians regarding the management of antithrombotic therapy during epistaxis, whilst there has been an increase in the use of anticoagulation and antiplatelet therapy. In addition, the introduction of direct oral anticoagulants (DOACs), such as dabigatran and rivaroxaban, over the last decade has significantly increased the complexity of managing the anticoagulated epistaxis patient. We undertook a systemic literature review investigating potential management strategies for each class of anti-thrombotic therapy during epistaxis. A PubMED and Cochrane Library search was performed on 10/03/16 using, but not limited to, the search terms epistaxis, nosebleed, nose bleeding, nasal haemorrhage, nasal bleeding AND each of the following search terms: antithrombotic, anticoagulant, antiplatelet, aspirin, clopidogrel, warfarin, dabigatran, rivaroxaban, apixaban and tranexamic acid. This yielded 3815 results, of which 29 were considered relevant. Other sources such as national and international guidelines related to the management of anti-thrombotics were also utilised. We present the findings related to the management of each class of anti-thrombotic therapy during epistaxis. Overall we found a lack of evidence regarding this topic and further high quality research is needed. This is an area growing in complexity and the support of colleagues in Haematology and Cardiology is increasingly important.

    theoretically high risk of complications should render the surgeon extremely cautious especially with young patients. Conceptually, the endoluminal treatment in the acute phase seems to be the solution and will probably become a preferred therapy while technical refinement is under way. Worldwide experience is growing and with this a better understanding of the indications and limitations of this innovative therapy will be elucidated. The clinical, diagnostic and management perspectives on aortic dissection and its variants, aortic intramural hematoma and atherosclerotic aortic ulcer, are reviewed.

    2012-02-01

    Endovascular stent graft treatment of acute thoracic aortic transections is an encouraging minimally invasive alternative to open surgical repair. Between 2006 and 2008, 16 patients with acute thoracic aortic transections underwent evaluation at our institution. Seven patients who were treated with an endovascular stent graft were reviewed. The mean Glasgow Coma Score was 13.0, probability of survival was .89, and median injury severity score was 32. The mean number of intensive care unit days was 7.7, mean number of ventilator support days was 5.4, and hospital length of stay was 10 days. Mean blood loss was 285 mL, and operative time was 143 minutes. Overall mortality was 14%. Procedure complications were a bleeding arteriotomy site and an endoleak. Endovascular treatment of traumatic thoracic aortic transections appears to demonstrate superior results with respect to mortality, blood loss, operative time, paraplegia, and procedure-related complications when compared with open surgical repair literature.

    Several studies suggest that local warming therapy (LWT) may help to treat chronic wounds, such as pressure ulcers, venous ulcers, arterial ulcers, and diabetic foot ulcers. However, evidence supporting the efficacy of this treatment is still incomplete. This study aimed to assess the effects of LWT in treating chronic wounds. For this review, we searched the Cochrane Wounds Specialized Register (March 6, 2017); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2017 issue 3); Ovid MEDLINE (1946 to March 6, 2017); Ovid Embase (1974 to March 6, 2017); EBSCO CINAHL (1982 to March 6, 2017); Chinese Biomedical Literature Database (1980 to March 20, 2017); China National Knowledge Infrastructure (1980 to March 20, 2017); VIP Information (1980 to March 20, 2017) (Chinese Database); and Wanfang Data (1980 to March 20, 2017). We did not apply date or language restrictions. Published or unpublished randomized controlled trials (RCTs) analyzing the effects of LWT in the treatment of chronic wounds (pressure ulcers, venous ulcers, arterial ulcers, and diabetic foot ulcers) were screened and selected. Two review authors independently conducted study selection, we planned that 2 review authors would also assess risk of bias and extract study data. No studies (RCTs) met the inclusion criteria for this review. Thus, it was impossible to undertake a meta-analysis or a narrative description of studies. The effects of LWT for treating chronic wounds are unclear because we did not identify any studies that met the inclusion criteria for this review. Quality improvement for LWT trials is urgently needed.

    Endovascular intervention has become the mainstay for treatment of most patients suffering from peripheral vascular disease. We describe a patient with a known nickel allergy who underwent placement of a stainless steel stent for aortoiliac occlusive disease. Despite our attempt to avoid a nickel-containing stent, the patient developed a diffuse rash consistent with a nickel or metal allergy. A review of stainless steel metallurgy revealed that nickel, cobalt, and titanium are frequently used to provide anticorrosive properties to stainless steel. The clinical significance of the use of nickel-alloy stents in the setting of patients with a nickel allergy is discussed. Published by Elsevier Inc.

    The most frequent risk in endovascular aneurysm treatment is thromboembolic complications. Thus adjuvant pharmaceuticals are largely focused on preventing and treating these latter. Additionally symptomatic treatment of subarachnoid hemorrhage (SAH) and treatments to avoid vasospasm will enter into play in cases of ruptured aneurisms. Consensus exists in the literature neither for the necessity of heparin or antiplatelets nor for the doses to be administered. The principles and rationale of the use of these medications are reviewed with a discussion of protocols according with clinical situations and technical choices.

    2016-12-01

    Chronic post-thrombotic obstruction of the inferior vena cava (IVC) or iliocaval junction is an uncommon complication of long indwelling IVC filter. When such an obstruction is symptomatic, endovascular treatment options include stent placement with or without filter retrieval. Filter retrieval becomes increasingly difficult with longer dwell times. We present a case of symptomatic post-thrombotic obstruction of the iliocaval junction related to Günther-Tulip IVC filter (Cook Medical Inc, Bloomington, IN) with dwell time of 4753 days, treated successfully with endovascular filter removal and stent reconstruction. Filter retrieval and stent reconstruction may be a treatment option in symptomatic patients with filter-related chronic IVC or iliocaval junction obstruction, even after prolonged dwell time.

    Fenestrated endografts are customized, patient-specific endovascular devices with potential to reduce morbidity and mortality of complex aortic aneurysm repair. With approval from the U.S. Food and Drug Administration, our center began performing fenestrated endovascular aneurysm repair through a physician-sponsored investigational device exemption (IDE #G130210), using both physician-modified endografts (PMEGs) and company-manufactured devices (CMDs). Because these techniques are associated with specific advantages and disadvantages, we sought to investigate differences in outcomes between PMEG and CMD cases. A single-institution retrospective review of all fenestrated endovascular aneurysm repairs was performed. The cohort was analyzed by device type (PMEG or CMD) after matching of cases on the basis of (1) number of target vessels intended for treatment, (2) extent of aneurysm, (3) aneurysm diameter, (4) device configuration, and (5) date of operation. Outcomes of ruptures, common iliac artery aneurysms, and aortic arch aneurysms were excluded. Demographics, operative details, perioperative complications, length of stay, and reinterventions were compared. For patients with >1 year of follow-up time, survival, type I or type III endoleak rate, target artery patency, and reintervention rate were estimated using the Kaplan-Meier method. Between November 30, 2010, and July 30, 2016, 82 patients were identified and matched. The cohort included 41 PMEG and 41 CMD patients who underwent repair of 38 juxtarenal (PMEG, 17; CMD, 21; P = .38), 14 pararenal (PMEG, 6; CMD, 8; P = .56), and 30 thoracoabdominal type I to type IV (PMEG, 18; CMD, 12; P = .17) aneurysms. There were significant differences in presentation requiring urgent aneurysm repair (PMEG, 9; CMD, 0; P = .002), total fluoroscopy time (PMEG, 76 minutes; CMD, 61 minutes; P = .02), volume of contrast material used (PMEG, 88 mL; CMD, 70 mL; P = .02), in-operating room to out-of-operating room time

  3. Permanent Leadless Cardiac Pacemaker Therapy: A Comprehensive Review.

    2017-04-11

    A new technology, leadless pacemaker therapy, was recently introduced clinically to address lead- and pocket-related complications in conventional transvenous pacemaker therapy. These leadless devices are self-contained right ventricular single-chamber pacemakers implanted by using a femoral percutaneous approach. In this review of available clinical data on leadless pacemakers, early results with leadless devices are compared with historical results with conventional single-chamber pacing. Both presently manufactured leadless pacemakers show similar complications, which are mostly related to the implant procedure: cardiac perforation, device dislocation, and femoral vascular access site complications. In comparison with conventional transvenous single-chamber pacemakers, slightly higher short-term complication rates have been observed: 4.8% for leadless pacemakers versus 4.1% for conventional pacemakers. The complication rate of the leadless pacemakers is influenced by the implanter learning curve for this new procedure. No long-term outcome data are yet available for the leadless pacemakers. Larger leadless pacing trials, with long-term follow-up and direct randomized comparison with conventional pacing systems, will be required to define the proper clinical role of these leadless systems. Although current leadless pacemakers are limited to right ventricular pacing, future advanced, communicating, multicomponent systems are expected to expand the potential benefits of leadless therapy to a larger patient population. © 2017 American Heart Association, Inc.

    Full Text Available Medullary thyroid cancers (MTCs constitute between 2 and 5% of all thyroid cancers. The 10-year overall survival (OS rate of patients with localized disease is around 95% while that of patients with regional stage disease is about 75%. Only 20% of patients with distant metastases at diagnosis survive 10 years which is significantly lower than for differentiated thyroid cancers. Cases with regional metastases at presentation have high recurrence rates. Adjuvant external radiation confers local control but not improved OS. The management of residual, recurrent, or metastatic disease till a few years ago was re-surgery with local measures such as radiation. Chemotherapy was used with marginal benefit. The development of targeted therapy has brought in a major advantage in management of such patients. Two drugs—vandetanib and cabozantinib—have been approved for use in progressive or metastatic MTC. In addition, several drugs acting on other steps of the molecular pathway are being investigated with promising results. Targeted radionuclide therapy also provides an effective treatment option with good quality of life. This review covers the rationale of targeted therapy for MTC, present treatment options, drugs and methods under investigation, as well as an outline of the adverse effects and their management.

    2010-01-01

    Photodynamic therapy (PDT) consists of a chemical reaction activated by light energy that is used to selectively destroy tissue. The reaction requires a photosensitizer in the target tissue, a light source and oxygen. The most extensively studied photosensitizing agents for PDT are 5-aminolevulinic acid for the treatment of actinic keratosis and methyl-aminolevulinate, which has been approved for the treatment of actinic keratosis, basal cell carcinoma and Bowen's disease. The light sources used in photodynamic therapy should emit light at wavelengths within the absorption spectrum of the photosensitizer used in PDT treatment. Light emitting diode (LED) lamps are indicated for the photodynamic treatment of nonmelanoma skin cancer. PDT should be considered as a therapeutic option, particularly in the case of patients with superficial, multiple or disseminated lesions and for immunosuppressed patients. More recently, PDT has been indicated for a wide range of dermatological conditions such as photo-damaged skin, acne, hidradenitis, scleroderma, psoriasis, warts and leishmaniosis, among others. This article provides an extensive review of photodynamic therapy, its mechanisms, indications and results.

    Objective: Epistaxis is a common clinical problem, and the majority of bleedings can be managed conservatively. However, due to extensive and sometimes life-threatening bleeding, further treatment, such as superselective embolization, may be required. We report our experience with endovascular treatment of life-threatening epistaxis. Methods: All patients presenting with excessive epistaxis, which received endovascular treatment at a German tertiary care facility between January 2001 and December 2009, were retrospectively identified. Demographic data, etiology, origin and clinical relevance of bleeding, interventional approach, therapy-associated complications, and outcome were assessed. Results: A total of 48 patients required 53 embolizations. Depending on the etiology of bleeding, patients were assigned to three groups: 1) idiopathic epistaxis (31/48), 2) traumatic or iatrogenic epistaxis (12/48), and 3) hereditary hemorrhagic telangiectasia (HHT) (5/48). Eleven of 48 patients required blood transfusions, and 9 of these 11 patients (82%) were termed clinically unstable. The sphenopalatine artery was embolized unilaterally in 10 of 53 (18.9%) and bilaterally in 41 of 53 (77.4%) procedures. During the same procedure, additional vessels were embolized in three patients (3/53; 5.7%). In 2 of 53(3.8%) cases, the internal carotid artery (ICA) was occluded. Long-term success rates of embolization were 29 of 31 (93.5%) for group 1 and 11 of 12 (91.7%) for group 2 patients. Embolization of patients with HHT offered at least a temporary relief in three of five (60%) cases. Two major complications (necrosis of nasal tip and transient hemiparesis) occurred after embolization. Conclusions: Endovascular treatment proves to be effective for prolonged and life-threatening epistaxis. It is easily repeatable if the first procedure is not successful and offers a good risk–benefit profile.

    STRUCTURED SUMMARY Background Celiac disease is managed by life-long gluten withdrawal from the diet. However strict adherence to a gluten-free diet is difficult and is not always effective. Novel therapeutic approaches are needed to supplement or even replace the dietary treatment. Aims To review recent advances in new therapeutic options for celiac disease. Methods A literature search was performed on MEDLINE, EMBASE, Web of Science, Scopus, DDW.org and ClinicalTrial.gov for English articles and abstracts. The search terms used include but not limited to “Celiac disease”, “new”, “novel”, Advances”, “alternatives” and “Drug therapy”. The cited articles were selected based on the relevancy to the review objective. Results Several new therapeutic approaches for celiac disease are currently under development by targeting its underlying pathogenesis. Alternative therapies range from reproduction of harmless wheat strains to immunomodulatory approaches. Some of these therapies such as enzymatic cleavage of gluten and permeability inhibitors have shown promise in clinical studies. Conclusion Gluten-free diet is still the only practical treatment for patients with celiac disease. Novel strategies provide promise of alternative adjunctive approaches to diet restriction alone for patients with this disorder. PMID:22324389

    Lung cancer is the leading cause of cancer-related deaths in the world. Conventional therapy for lung cancer is associated with lack of specificity and access to the normal cells resulting in cytotoxicity, reduced cellular uptake, drug resistance and rapid drug clearance from the body. The emergence of nanotechnology has revolutionized the treatment of lung cancer. The focus of nanotechnology is to target tumor cells with improved bioavailability and reduced toxicity. In the recent years, nanoparticulate systems have extensively been exploited in order to overcome the obstacles in treatment of lung cancer. Nanoparticulate systems have shown much potential for lung cancer therapy by gaining selective access to the tumor cells due to surface modifiability and smaller size. In this review, various novel nanoparticles (NPs) based formulations have been discussed in the treatment of lung cancer. Nanotechnology is expected to grow fast in future, and it will provide new avenues for the improved treatment of lung cancer. This review article also highlights the characteristics, recent advances in the designing of NPs and therapeutic outcomes.

    To determine the effectiveness of music therapy in asthma. Searches for experimental and observational studies published between 01.01.92 and 31.12.13 were conducted through electronic databases: Medline/PubMed, Embase, SportDiscus, Cochrane Library, Teacher Reference Centre, Web of Science, Academic Search Complete, PsycINFO, PsycARTICLES, PEDro and Scopus. The selection criteria included any method of music therapy applied to patients with asthma, with respect to asthma symptoms and lung function. Two reviewers screened the records independently. The risk of bias was assessed using the Cochrane Collaboration's tool. Strength of recommendation was graded according to GRADE recommendation. The literature search identified 867 citations, from which 8 (three RCTs and five nRCTs) low and high risk of bias studies were included in the review. All RCTs used music listening as a form of complementary treatment. One RCT of the low risk of bias indicated positive effects on lung function in mild asthma. In two others, despite the decrease in asthma symptoms, music was not more effective than the control condition. In two nRCTs a decrease in asthma symptoms was reported as an effect of playing a brass or wind instrument; in two nRCTs the same effect was observed after music assisted vocal breathing exercises and singing. Mood improvement, decrease of depression and anxiety were also observed. The paucity, heterogeneity, and significant methodological limitations of available studies allow for only a weak recommendation for music therapy in asthma. This study highlights the need for further research of mixed methodology. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Manual therapy is often used for patients with neck pain with or without radicular symptoms. There is sparse evidence on the effectiveness in cervical radiculopathy. The aim of this study was to assess current levels of evidence on the effectiveness of manual therapy interventions for patients with cervical radiculopathy. Electronic data bases were systematically searched for clinical guidelines, reviews and randomised clinical trials (RCTs) reporting on the effectiveness of manual therapy for patients with cervical radiculopathy. Eight relevant reviews, two guidelines and two recent RCTs, that had not yet been included in either, were retrieved. The overall quality of the evidence of included studies was evaluated using the GRADE method. Most interventions were only studied in one single RCT. There is low level evidence that cervical manipulation and mobilisation as unimodal interventions are effective on pain and range of motion at the immediate follow up, but no evidence on the effectiveness of thoracic manipulation or mobilisation as unimodal interventions. There is low level evidence that a combination of spinal mobilisation and motor control exercises is more effective on pain and activity limitations than separate interventions or a wait-and-see policy. There is low level evidence of the effectiveness of cervical mobilisation with a neurodynamical intent as unimodal intervention, on the effectiveness of a multimodal intervention with neurodynamic intent on pain activity limitations and global perceived effect compared to a wait-and-see policy. There is also low level evidence that a multimodal intervention consisting of spinal and neurodynamic mobilisations and specific exercises is effective on pain in patients with CR. There is low level evidence that traction is no more effective than placebo traction.

This is particularly true for those patients who are at risk of type II respiratory failure in whom the risk of hypercapnia is well established. In recent times, several international bodies have advocated for the prescription of oxygen therapy in an attempt to reduce this risk in vulnerable patient groups. Despite this guidance, published data have demonstrated that there has been poor uptake of these recommendations. Multiple interventions have been tested to improve concordance, and while some of these interventions show promise, the sustainability of these interventions are less convincing. In this review, we summarize data that have been published on the prevalence of oxygen prescription and the accurate and appropriate administration of this drug therapy. We also identify strategies that have shown promise in facilitating changes to oxygen prescription and delivery practice. There is a clear need to investigate the barriers, facilitators, and attitudes of clinicians in relation to the prescription of oxygen therapy in acute care. Interventions based on these findings then need to be designed and tested to facilitate the application of evidence-based guidelines to support sustained changes in practice, and ultimately improve patient care.

    Full Text Available Static magnetic field (SMF therapy, applied via a permanent magnet attached to the skin, is used by people worldwide for self-care. Despite a lack of established SMF dosage and treatment regimens, multiple studies are conducted to evaluate SMF therapy effectiveness. Our objectives in conducting this review are to: (i summarize SMF research conducted in humans; (ii critically evaluate reporting quality of SMF dosages and treatment parameters and (iii propose a set of criteria for reporting SMF treatment parameters in future clinical trials. We searched 27 electronic databases and reference lists. Only English language human studies were included. Excluded were studies of electromagnetic fields, transcranial magnetic stimulation, magnets placed on acupuncture points, animal studies, abstracts, posters and editorials. Data were extracted on clinical indication, study design and 10 essential SMF parameters. Three reviewers assessed quality of reporting and calculated a quality assessment score for each of the 10 treatment parameters. Fifty-six studies were reviewed, 42 conducted in patient populations and 14 in healthy volunteers. The SMF treatment parameters most often and most completely described were site of application, magnet support device and frequency and duration of application. Least often and least completely described were characteristics of the SMF: magnet dimensions, measured field strength and estimated distance of the magnet from the target tissue. Thirty-four (61% of studies failed to provide enough detail about SMF dosage to permit protocol replication by other investigators. Our findings highlight the need to optimize SMF dosing parameters for individual clinical conditions before proceeding to a full-scale clinical trial.

    Endovascular stent grafting has been increasingly used as an alternative treatment modality. The aim of this study is to evaluate the immediate and short-term results of endovascular stent grafting repair after blunt thoracic aortic injury due to trauma. A review of a tertiary trauma center registry identified all patients who suffered blunt thoracic aortic injury from 2002 to 2006. All patients underwent either open repair with synthetic graft interposition or endovascular stent grafting (EVS) of the descending thoracic aorta. Type and severity of injury, concomitant injuries, clinical factors, and outcome were compared between groups. Univariate and multivariate analysis was performed. Endovascular stent grafting was performed in 22 patients, and 10 patients underwent open surgical repair. In the open group, the 30-day mortality rate was 10%, the paraplegia rate was 10%, and incidence of major complications was 30%, which were comparable with the incidences observed in the EVS group of 4.5%, 4.5%, and 13.6%, respectively. No statistically significant differences were demonstrated. Multivariate regression analysis identified associated thoracic injury as the main independent predictor of hospital length of stay (p = 0.03, 95% confidence interval: 0.53 to 18.85). In the EVS group, 1 patient died in the short-term follow-up period and 2 cases of endovascular leak required additional treatment. Although postoperative mortality and morbidity between open and endovascular repair were comparable, EVS can be considered a safe alternative treatment modality in the therapeutic algorithm of blunt thoracic aortic injury particularly for the higher risk multitrauma patients.

    To audit the caseloads of vascular surgery residents in the management of disabling claudication and assess the influence of endovascular procedures on overall operative experience. A retrospective review was conducted of vascular surgery resident experience in the open and endovascular management of lower limb claudication during two 3-year periods (January 2000 to December 2002 and January 2003 to December 2005). The time periods differed with regard to number of surgical faculty with advanced endovascular skills (3 in the first period and 4 in the second) and the availability of portable operating room angiography equipment. During the 6-year period, the operative logs of vascular surgery residents indicated participation in 283 procedures [170 (60%) open surgical interventions, including 146 suprainguinal procedures] performed for claudication. The number of procedures increased by 62% (pocclusive disease increased 4-fold (14 versus 56 interventions, p=0.01) compared to a decrease in open (bypass grafting, endarterectomy) surgical repair (45 to 31 procedures, p=0.22). The greatest change in resident experience was in endovascular intervention of infrainguinal occlusive disease: the case volume increased from 4 to 39 procedures (p=0.07) during the 2 time intervals. By contrast, the number of open surgical bypass procedures was similar (45 versus 49) in each 3-year period. An audit of resident experience demonstrated intervention for claudication has increased during the past 6 years. The increased operative experience reflects more endovascular treatment (atherectomy, angioplasty, stent-graft placement) of femoropopliteal and aortoiliac occlusive disease, but no decrease in open surgical operative experience for claudication. This increase in endovascular intervention may be related to a decrease in the threshold for intervention.

    Optimal treatment of intracranial aneurysms involves complete occlusion of the aneurysm with preservation of the parent artery and all of its branches. Attempts to occlude the aneurysm and preserve the parent artery may be associated with a higher level of risk than parent vessel occlusion or trapping. To evaluate our series of patients with large and giant aneurysms who underwent treatment via endovascular coiling with parent artery sacrifice or surgical ligation of the common carotid artery (CCA) and gain insight into the advantages and risks of each of these alternatives. We retrospectively reviewed all patients with aneurysms who underwent carotid sacrifice via endovascular occlusion or surgical CCA ligation during an 8-year period at our institution. Twenty-seven patients with large and giant aneurysms of the internal carotid artery underwent carotid artery sacrifice via endovascular occlusion (n = 15) or CCA ligation (n = 12). Of the patients who underwent endovascular occlusion, 3 developed groin complications, 1 developed a new sixth nerve palsy, 1 died from vasospasm related to subarachnoid hemorrhage, and 1 died secondary to rupture of an associated 3-mm anterior communicating artery aneurysm 5 days postoperatively. Of the patients undergoing CCA ligation, 1 patient developed a partial hypoglossal palsy. Clinical improvement of presenting symptoms was observed in all surviving patients regardless of the method of treatment. Complete aneurysm obliteration was documented in all patients during the initial hospital stay. The mean radiographic long-term follow-up was 14.2 months, which was available in 20 of the 25 surviving patients (80%). Complete obliteration was confirmed at follow-up in all but 2 patients with large cavernous aneurysms; 1 was initially treated with endovascular occlusion and the other with carotid ligation. Parent artery sacrifice is still a viable treatment for some complex aneurysms of the internal carotid artery. CCA ligation is a

    Full Text Available BACKGROUND: Postherpetic neuralgia (PHN is a complication of acute herpes zoster, which is emerging as a preferred clinical trial model for chronic neuropathic pain. Although there are published meta-analyses of analgesic therapy in PHN, and neuropathic pain in general, the evidence base has been substantially enhanced by the recent publication of several major trials. Therefore, we have conducted a systematic review and meta-analysis for both efficacy and adverse events of analgesic therapy for PHN. METHODS AND FINDINGS: We systematically searched databases (MEDLINE 1966-2004, EMBASE 1988-2004, CINAHL 1982-2002, and PubMed [29 October 2004] for trials of PHN. We also searched references of retrieved studies and review articles for further trials. We included trials that examined adult patients with PHN of greater duration than 3 mo, that were blinded, randomised, and had at least one measure of pain outcome. Dichotomous pain outcome data were extracted for 50% decrease in baseline pain using a hierarchy of pain/pain-relief measurement tools. Where available, dichotomous data were also collected for adverse events. Calculated estimates of efficacy included relative benefit and number needed to treat. Of 62 studies identified, 35 were randomised controlled trials. Of these, 31 were placebo controlled and suitable for meta-analysis, from which it was possible to extract dichotomous efficacy outcome data from 25. This meta-analysis revealed that there is evidence to support the use of the following orally administered therapies: tricyclic antidepressants, "strong" opioids, gabapentin, tramadol, and pregabalin. Topical therapies associated with efficacy were lidocaine 5% patch and capsaicin. Finally, a single study of spinal intrathecal administration of lidocaine and methyl prednisolone demonstrated efficacy, although this has yet to be replicated. Data suggest that the following therapies are not associated with efficacy in PHN: certain NMDA

    Full Text Available End-stage kidney disease (ESKD patients are often prescribed multiple medications. Together with a demanding weekly schedule of dialysis sessions, increased number of medicines and associated regimen complexity pre-dispose them at high risk of medication nonadherence. This review summarizes existing literature on nonadherence and identifies factors associated with nonadherence to medication therapy in patients undergoing haemodialysis.A comprehensive search of PubMed, Embase, CINAHL, PsycInfo, and Cochrane Database of Systematic Reviews covering the period from 1970 through November 2014 was performed following a predefined inclusion and exclusion criteria. Reference lists from relevant materials were reviewed. Data on study characteristics, measures of nonadherence, prevalence rates and factors associated with nonadherence were collected. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA guidelines was followed in conducting this systematic review.Of 920 relevant publications, 44 were included. The prevalence of medication nonadherence varied from 12.5% to 98.6%, with widespread heterogeneity in measures and definitions employed. Most common patient-related factors significantly associated with nonadherence were younger age, non-Caucasian ethnicity, illness interfering family life, being a smoker, and living single and being divorced or widowed. Similarly, disease-related factors include longevity of haemodialysis, recurrent hospitalization, depressive symptoms and having concomitant illness like diabetes and hypertension. Medication-related factors such as daily tablet count, total pill burden, number of phosphate binders prescribed and complexity of medication regimen were also associated with poor adherence.A number of patient-, disease-, and medication-related factors are associated with medication nonadherence in haemodialysis patients. Clinicians should be aware of such factors so that adherence to medications

    A variety of workplace-based interventions exist to reduce stress and increase productivity. However, the efficacy of these interventions is sometimes unclear. To determine whether complementary therapies offered in the workplace improve employee well-being. We performed a systematic literature review which involved an electronic search of articles published between January 2000 and July 2015 from the databases Cochrane Central Register of Controlled Trials, PsycINFO, MEDLINE, AMED, CINAHL Plus, EMBASE and PubMed. We also undertook a manual search of all applicable article reference lists to ensure that no relevant studies were missed. We only selected published, full-length, English-language, peer-reviewed journal articles. Articles had to address the research objective using valid and reliable measures. We excluded articles concerning return to work or whose populations had been adversely affected by work resulting in the development of health issues. We included 10 articles in the review from 131 identified. Mindfulness and meditation-based interventions were most effective in improving workplace health and work performance; the latter demonstrating some evidence of maintaining gains up to 3 months later. The evidence for relaxation interventions was inconclusive. Mindfulness and meditation interventions may be helpful in improving both psychosocial workplace health and work performance, but long-term efficacy has yet to be fully determined. © The Author 2016.

    Full Text Available Pediatric intracranial aneurysm rupture is rare, and is traditionally managed by surgical clipping. To the best of our knowledge, endovascular embolization of aneurysms in neonates has not previously been reported in Taiwan. We report a 9-day-old boy with intracranial aneurysms who underwent endovascular embolization, representing the youngest reported case in Taiwan. The 9-day-old boy presented with non-specific symptoms of irritable crying, seizure and respiratory distress. Computed tomography disclosed intraventricular hemorrhage, subarachnoid hemorrhage and focal intracranial hemorrhage around the right cerebellum. Subsequent computed tomographic angiography showed two sequential fusiform aneurysms, measuring 3 mm, located in the right side posterior inferior cerebellar artery (PICA. The patient underwent endovascular embolization because of the high risk of aneurysm re-rupture and the impossibility of surgical clipping due to the fusiform nature of the aneurysms. A postembolization angiogram revealed complete obliteration of the right distal PICA and proximal aneurysm. The distal PICA aneurysm was revascularized from the collateral circulation, but demonstrated a slow and delayed filling pattern. The patient's condition remained stable over the following week, and he was discharged without anticonvulsant therapy. No significant developmental delay was noted at follow-up at when he was 3 months old. This case emphasizes the need for clinical practitioners to consider a diagnosis of intracranial hemorrhage in neonates with seizure and increased intracranial pressure. Neonatal intracranial aneurysms can be treated safely by endovascular treatment.

    Fenestration of the vertebrobasilar junction (VBJ) is a rare condition which may be associated with the presence of aneurysms. The endovascular approach is usually the first-line treatment in these cases since the location of the aneurysm may be unsuitable for a surgical approach. This anatomical variation may even influence the endovascular strategy, particularly in those cases in which the sacrifice of a vessel could be avoided. This paper describes an innovative approach of flow diversion in such challenging situations. Two women were admitted after an occasional diagnosis of an aneurysm arising from a fenestrated VBJ. In both cases the endovascular approach was performed with two flow diverter stents and dual antiplatelet therapy was administered for 6 months. Complete exclusion of the two aneurysms was obtained after 6 and 7 months, respectively, and the clinical outcome was excellent. Endovascular treatment of unruptured aneurysms located on a fenestrated VBJ with flow diverter stents represents a valid therapeutic approach with excellent clinical and radiological outcomes.

    Background: Endovascular neurosurgery is known to be associated with potentially serious perioperative complications that can impact the course and outcome of anesthesia. We present here our institutional experience in the anesthetic management of various endovascular neurosurgical procedures and their related complications over a 10-year period. Methods: Data was obtained in 240 patients pertaining to their preoperative status, details of anesthesia and surgery, perioperative course and surgery-related complications. Information regarding hemodynamic alterations, temperature variability, fluid-electrolyte imbalance, coagulation abnormalities and alterations in the anesthesia course was specifically noted. Results: Among the important complications observed were aneurysm rupture (2.5%), vasospasm (6.67%), thromboembolism (4.16%), contrast reactions, hemodynamic alterations, electrolyte abnormalities, hypothermia, delayed emergence from anesthesia, groin hematomas and early postoperative mortality (5.14%). Conclusion: Awareness of the unique challenges of endovascular neurosurgery and prompt and appropriate management of the associated complications by an experienced neuroanesthesiologist is vital to the outcome of these procedures.

    2018-02-01

    The goal of this review is to explore alternative neurological therapies in the treatment of alcohol use disorder; including transcranial direct current stimulation (tDCS), transcranial magnetic stimulation, deep brain stimulation (DBS), electroconvulsive therapy (ECT), and the off-label use of the GABA B receptor agonist baclofen. A comprehensive literature search was conducted through EBSCOhost regarding the neurological therapies in the treatment of alcoholism discussed in this paper. To date, few studies have been conducted on the subject, sample sizes are consistently small, and long-term abstinence appears a common problem. tDCS has shown to temporarily reduce alcohol cravings but with a high number of long-term relapses, 50-70%. DBS and TMS, similarly, fail to overcome high relapse rates. In one DBS study, for example, only two of five patients achieved prolonged abstinence. ECT seems to avoid such problems, but only a single case study exists to date. As such, no solid conclusions can be made regarding its success in alcohol addiction treatment. Baclofen, however, implicated in studies with comparatively larger patient samples and higher efficacy rates, presents with great promise, particularly in patients with more severe forms of AUD. In one of the largest observational studies to date (100 subjects) 92% of patients reported craving suppression and long-term relapse rates were low. The side-effects of oral baclofen (i.e., somnolence, insomnia, dizziness, paresthesia, etc.) though, pose a principle limitation to its administration in alcohol addiction. Based on current information in the literature, the authors advocate that, following more extensive research on oral baclofen and its indications in the treatment of alcohol addiction, intrathecal administration be the next logical therapeutic option to be explored. In particular, those patients with severe AUD, requiring high doses of the medication, may benefit, as it eliminates the systemic side effects

It is a common condition, but often underdiagnosed and undertreated. The indication of testosterone-replacement therapy (TRT treatment requires the presence of low testosterone level, and symptoms and signs of hypogonadism. Although controversy remains regarding indications for testosterone supplementation in aging men due to lack of large-scale, long-term studies assessing the benefits and risks of testosterone-replacement therapy in men, reports indicate that TRT may produce a wide range of benefits for men with hypogonadism that include improvement in libido and sexual function, bone density, muscle mass, body composition, mood, erythropoiesis, cognition, quality of life and cardiovascular disease. Perhaps the most controversial area is the issue of risk, especially possible stimulation of prostate cancer by testosterone, even though no evidence to support this risk exists. Other possible risks include worsening symptoms of benign prostatic hypertrophy, liver toxicity, hyperviscosity, erythrocytosis, worsening untreated sleep apnea or severe heart failure. Despite this controversy, testosterone supplementation in the United States has increased substantially over the past several years. The physician should discuss with the patient the potential benefits and risks of TRT. The purpose of this review is to discuss what is known and not known regarding the benefits and risks of TRT.Keywords: hypogonadism, testosterone replacement therapy, erectile dysfunction, osteoporosis, cardiovascular disease

  10. Stimulus characteristics in electroconvulsive therapy. A pragmatic review.

    Science.gov (United States)

    Sanz-Fuentenebro, Francisco Javier

    The process of normalization electroconvulsive therapy (ECT) requires, among other actions, disseminating the latest information on this technique. One of the most complex aspects is the electrical stimulus, whose knowledge should be spread and put into practice. In this paper we review the available information about frequency and number of ECT sessions, and efficacy of each electrode placement. We also present two approaches to determine the ECT charge: stimulus titration versus age-based method; and the limitations of the summary metrics of charge, being necessary to expand our knowledge of the parameters that configure the stimulus: duration, current amplitude frequency and pulse width.

    Growth hormone (GH) has significant effects on linear bone growth, bone mass and bone metabolism. The primary role of GH supplementation in children with GH deficiency, those born small for gestational age or with other types of disorders in somatic development is to increase linear growth. However, GH therapy seems to elicit varying responses in the craniofacial region. Whereas the effects of GH administration on somatic development are well documented, comparatively little is known of its effects on the craniofacial region. The purpose of this review was to search the literature and compile results from both animal and human studies related to the impact of GH on craniofacial growth. © 2012 John Wiley & Sons A/S.

    Peripheral artery disease affects >200 million people worldwide and is associated with significant limb and cardiovascular morbidity and mortality. Limb revascularization is recommended to improve function and quality of life for symptomatic patients with peripheral artery disease with intermittent claudication who have not responded to medical treatment. For patients with critical limb ischemia, the goals of revascularization are to relieve pain, help wound healing, and prevent limb loss. The baseline risk of cardiovascular and limb-related events demonstrated among patients with stable peripheral artery disease is elevated after revascularization and related to atherothrombosis and restenosis. Both of these processes involve platelet activation and the coagulation cascade, forming the basis for the use of antiplatelet and anticoagulant therapies to optimize procedural success and reduce postprocedural cardiovascular risk. Unfortunately, few high-quality, randomized data to support use of these therapies after peripheral artery disease revascularization exist, and much of the rationale for the use of antiplatelet agents after endovascular peripheral revascularization is extrapolated from percutaneous coronary intervention literature. Consequently, guideline recommendations for antithrombotic therapy after lower limb revascularization are inconsistent and not always evidence-based. In this context, the purpose of this structured review is to assess the available randomized data for antithrombotic therapy after peripheral arterial revascularization, with a focus on clinical trial design issues that may affect interpretation of study results, and highlight areas that require further investigation. © 2017 American Heart Association, Inc.

    More than 80% of infrarenal aortic aneurysms are treated by endovascular repair. However, adoption of fenestrated and branched endovascular repair for complex aortic aneurysms has been limited, despite high morbidity and mortality associated with open repair. There are few published reports of consecutive outcomes, inclusive of all fenestrated and branched endovascular repairs, starting from the inception of a complex aortic aneurysm program. Therefore, we examined a single center's consecutive experience of fenestrated and branched endovascular repair of complex aortic aneurysms. This is a single-center, prospective, observational cohort study evaluating 30-day and 1-year outcomes in all consecutive patients who underwent fenestrated and branched endovascular repair of complex aortic aneurysms (definition: requiring one or more fenestrations or branches). Data were collected prospectively through an Institutional Review Board-approved registry and a physician-sponsored investigational device exemption clinical trial (G130210). We performed 100 consecutive complex endovascular aortic aneurysm repairs (November 2010 to March 2016) using 58 (58%) commercially manufactured custom-made devices and 42 (42%) physician-modified devices to treat 4 (4%) common iliac, 42 (42%) juxtarenal, 18 (18%) pararenal, and 36 (36%) thoracoabdominal aneurysms (type I, n = 1; type II, n = 4; type III, n = 12; type IV, n = 18; arch, n = 1). The repairs included 309 fenestrations, branches, and scallops (average of 3.1 branch arteries/case). All patients had 30-day follow-up for 30-day event rates: three (3%) deaths; six (6%) target artery occlusions; five (5%) progressions to dialysis; eight (8%) access complications; one (1%) paraparesis; one (1%) bowel ischemia; and no instances of myocardial infarction, paralysis, or stroke. Of 10 type I or type III endoleaks, 8 resolved (7 with secondary intervention, 1 without intervention). Mean follow-up time was 563 days (interquartile range

    Full Text Available Evidence regarding the health consequences of smoking is undeniable, yet 21% of the American population continues to smoke. In addition to behavioral modifications, first-line treatment options include nicotine replacement therapies and bupropion SR. Varenicline, which was recently approved by the Food and Drug Administration (FDA, offers a novel mechanism of action for smoking cessation. This article reviews current first-line smoking cessation aids and evaluates the clinical trials pertaining to the efficacy and safety of varenicline. Additionally, the authors attempt to establish the role of varenicline in smoking cessation therapy and determine whether varenicline should be used prior to other first-line smoking cessation aids, particularly considering the lower costs of generic alternatives. At present, clinical studies have not established the efficacy of varenicline after repeated courses, following bupropion failures, or in various unstudied populations. Relatively poor study outcomes emphasize the need to provide patients with behavioral counseling throughout each quit attempt and for 1 year past the quit date.

    For decades, B cells were ignored in multiple sclerosis (MS) pathogenesis, and the disease was always regarded as a T cell-mediated disorder. Recent evidence shows that there is an antigen-driven B-cell response in the central nervous system of patients with MS, and memory B cells/plasma cells are detectable in MS lesions. The striking efficacy of B cell-depleting therapies in reducing the inflammatory activity of the disease highlights that B cells may play more pathogenetic roles than expected. B cells express several unique characteristic markers on their surface, for example, CD19, CD20 molecules, that provide selective targets for monoclonal antibodies. In this respect, several B cell-targeted therapies emerged, including anti-CD20 antibodies (rituximab, ocrelizumab, and ofatumumab), anti-CD19 antibody (inebilizumab), and agents targeting the BAFF/APRIL signaling pathway (atacicept, belimumab, and LY2127399). In this review, we discuss, in detail, the immunobiology of B cells and their protective and destructive roles in MS pathogenesis. In the second part, we list the completed and ongoing clinical trials investigating the safety and efficacy of B cell-related monoclonal antibodies in MS. © 2018 John Wiley & Sons A/S.

    Hyperthermia treatment, generated by magnetic nanoparticles (MNPs) is promising since it is tumour-focused, minimally invasive and uniform. The most unique feature of magnetic nanoparticles is its reaction and modulation by a magnetic force basically responsible for enabling its potential as heating mediators for cancer therapy. In magnetic nanoparticle hyperthermia, a tumour is preferentially loaded with systemically administered nanoparticles with high-absorption cross-section for transduction of an extrinsic energy source to heat. To maximize the energy deposited in the tumour while limiting the exposure to healthy tissues, the heating is achieved by exposing the region of tissue containing magnetic nanoparticles to an alternating magnetic field. The magnetic nanoparticles dissipate heat from relaxation losses thereby heating localized tissue above normal physiological ranges. Besides thermal efficiency, the biocompatibility of magnetite nanoparticles assisted its deployment as efficient drug carrier for targeted therapeutic regimes. In the present article, we provide a state-of-the-art review focused on progress in nanoparticle induced hyperthermia treatments that have several potential advantages over both global and local hyperthermia treatments achieved without nanoparticles. Green bio-nanotechnology has attracted substantial attention and has demonstrable abilities to improve cancer therapy. Furthermore, we have listed the challenges associated with this treatment along with future prospective that could attract the interest of biomedical engineers, biomaterials scientists, medical researchers and pharmacological research groups.

  17. Cognitive behavioral therapy for schizophrenia: an empirical review.

    Science.gov (United States)

    Rector, Neil A; Beck, Aaron T

    2012-10-01

    Early case studies and noncontrolled trial studies focusing on the treatment of delusions and hallucinations have laid the foundation for more recent developments in comprehensive cognitive behavioral therapy (CBT) interventions for schizophrenia. Seven randomized, controlled trial studies testing the efficacy of CBT for schizophrenia were identified by electronic search (MEDLINE and PsychInfo) and by personal correspondence. After a review of these studies, effect size (ES) estimates were computed to determine the statistical magnitude of clinical change in CBT and control treatment conditions. CBT has been shown to produce large clinical effects on measures of positive and negative symptoms of schizophrenia. Patients receiving routine care and adjunctive CBT have experienced additional benefits above and beyond the gains achieved with routine care and adjunctive supportive therapy. These results reveal promise for the role of CBT in the treatment of schizophrenia although additional research is required to test its efficacy, long-term durability, and impact on relapse rates and quality of life. Clinical refinements are needed also to help those who show only minimal benefit with the intervention.

    Full Text Available ABSTRACT Objective: to investigate the evidence available in the literature on non-adherence to immunosuppressive therapy among patients undergoing liver transplantation. Method: integrative literature review, including research whose sample consisted of patients aged over 18 years undergoing liver transplantation. It excluded those containing patients undergoing multiple organ transplants. For the selection of articles, Medline / Pubmed, CINAHL, LILACS, Scopus and Embase were searched. The search period corresponded to the initial date of indexation of different bases, up to the deadline of February 10, 2015, using controlled and uncontrolled descriptors: liver transplantation, hepatic transplantation, liver orthotopic transplantation, medication adherence, medication non-adherence, medication compliance and patient compliance. Results: were located 191 investigations, 10 of which met the objectives of the study and were grouped into four categories, namely: educational process and non-adherence; non-adherence related to the number of daily doses of immunosuppressive medications; detection methods for non-adherence and side effects of therapy. Conclusion: there were risk factors related to the health service, such as control and reduction of the number of doses; related to the individual, such as being male, divorced, alcohol or other substances user, exposed to low social support and being mentally ill.

  19. A review of antibiotic therapy for pelvic inflammatory disease.

    2015-09-01

    Pelvic inflammatory disease (PID) is a gynaecological inflammatory disorder with a high incidence that can lead to sequelae such as infertility, ectopic pregnancy and chronic pelvic pain. The International Union against Sexually Transmitted Infections (IUSTI) and the US Centers for Disease Control and Prevention (CDC) have issued treatment recommendations for the management of PID. The purpose of this review is to summarise the available evidence for the use of IUSTI- and CDC-recommended antibiotic therapies for PID. The main differences between recommendations concern alternative regimens for inpatient treatment and the use of oral moxifloxacin as an alternative outpatient regimen in the IUSTI guidelines. There is evidence supporting the use of the recommended antibiotic regimens, although with some variation in reported cure rates. This variation can be explained, in part, by the different diagnostic and evaluation criteria used in different trials. Adverse events that require discontinuation of antibiotic therapy are rarely observed. The main limitation of the current available evidence is the short-term follow-up, which does not allow full evaluation of the risks of long-term sequelae.

  20. A Surgical View of Photodynamic Therapy in Oncology: A Review

    Science.gov (United States)

    Moghissi, K.; Dixon, Kate; Gibbins, Sally

    2015-01-01

    Clinical photodynamic therapy (PDT) has existed for over 30 years, and its scientific basis has been known and investigated for well over 100 years. The scientific foundation of PDT is solid and its application to cancer treatment for many common neoplastic lesions has been the subject of a huge number of clinical trials and observational studies. Yet its acceptance by many clinicians has suffered from its absence from the undergraduate and/or postgraduate education curricula of surgeons, physicians, and oncologists. Surgeons in a variety of specialties many with years of experience who are familiar with PDT bear witness in many thousands of publications to its safety and efficacy as well as to the unique role that it can play in the treatment of cancer with its targeting precision, its lack of collateral damage to healthy structures surrounding the treated lesions, and its usage within minimal access therapy. PDT is closely related to the fluorescence phenomenon used in photodiagnosis. This review aspires both to inform and to present the clinical aspect of PDT as seen by a surgeon. PMID:28824964

  1. Antipurinergic therapy for autism-An in-depth review.

    Naviaux, Robert K

    2017-12-16

    Are the symptoms of autism caused by a treatable metabolic syndrome that traces to the abnormal persistence of a normal, alternative functional state of mitochondria? A small clinical trial published in 2017 suggests this is possible. Based on a new unifying theory of pathogenesis for autism called the cell danger response (CDR) hypothesis, this study of 10 boys, ages 5-14years, showed that all 5 boys who received antipurinergic therapy (APT) with a single intravenous dose of suramin experienced improvements in all the core symptoms of autism that lasted for 5-8weeks. Language, social interaction, restricted interests, and repetitive movements all improved. Two children who were non-verbal spoke their first sentences. None of these improvements were observed in the placebo group. Larger and longer studies are needed to confirm this promising discovery. This review introduces the concept of M2 (anti-inflammatory) and M1 (pro-inflammatory) mitochondria that are polarized along a functional continuum according to cell stress. The pathophysiology of the CDR, the complementary functions of M1 and M2 mitochondria, relevant gene-environment interactions, and the metabolic underpinnings of behavior are discussed as foundation stones for understanding the improvements in ASD behaviors produced by antipurinergic therapy in this small clinical trial.

    Postpartum depression can have devastating consequences on the mother and child. Prompt treatment is challenging. Whereas electroconvulsive therapy (ECT) is considered to be an effective treatment modality in severe depression and brings about rapid clinical improvement, little is known about ECT during the postpartum period. We systematically reviewed the literature on the use of ECT during the postpartum period using PubMed, Institute for Scientific Information Web of Knowledge and PsycINFO databases until September 2014, using the search terms "electroconvulsive therapy" or "ECT" and "postpartum". Then, we described the successful treatment with ECT and the joint mother-baby hospitalization of a woman with severe depression. Eight case reports and 8 studies were identified. All of the studies reported that ECT is effective in the postpartum period. It is well tolerated, provides a fast response and allows for breastfeeding. In addition, our case report showed the benefits of the hospitalization of the mother-baby unit. Combined ECT and joint mother-baby hospitalization could be a valuable treatment by targeting both the mother-infant relationship and the maternal depressive symptoms. Copyright © 2015 Elsevier Inc.

  3. Review of Current Immunologic Therapies for Hidradenitis Suppurativa

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Hidradenitis suppurativa (HS is a chronic, recurrent, inflammatory disease of apocrine gland-bearing skin which affects approximately 1–4% of the population. The disease is more common in women and patients of African American descent and approximately one-third of patients report a family history. Obesity and smoking are known risk factors, but associations with other immune disorders, especially inflammatory bowel disease, are also recognized. The pathogenesis of HS is poorly understood and host innate or adaptive immune response, defective keratinocyte function, and the microbial environment in the hair follicle and apocrine gland have all been postulated to play a role in disease activity. While surgical interventions can be helpful to reduce disease burden, there is a high recurrence rate. Increasingly, data supports targeted immune therapy for HS, and longitudinal studies suggest benefit from these agents, both when used alone and as an adjunct to surgical treatments. The purpose of this review is to outline the current data supporting use of targeted immune therapy in HS management.

  4. Occupational therapy in the hospital context: an integrative literature review

    Claudia Aline Valente Santos

    2013-04-01

    Full Text Available This study evaluated the scientific knowledge produced and published in journals indexed in major international databases, covering the area of Occupational Therapy (OT in hospitals. To this end, an integrative literature review was carried out with 17 selected articles published between 2004 and 2009, indexed in the following databases: LILACS, SciELO and MEDLINE. Studies show that the performance of an occupational therapist with hospitalized patients provides improvements in the hospitalization condition, higher levels of independence, function and quality of life, and facilitates the resumption of everyday life and social participation of individuals. The recent scientific production in Occupational Therapy regarding hospital contexts seems to be more directed to the report of experiences than to the evidence for effectiveness of actions developed through planned and controlled clinical and/or experimental studies. This type of production certainly contributes not only to a better dissemination and development of successful and effective therapeutic practices, but also to greater recognition of the need and importance of the occupational therapist in the composition of health teams in hospitals. However, productions with greater scientific consistency within internationally accepted standards are necessary.

    Since the discovery of bacteriophages at the beginning of the 19th century their contribution to bacterial evolution and ecology and use in a variety of applications in biotechnology and medicine has been recognized and understood. Bacteriophages are natural bacterial killers, proven as best biocontrol agents due to their ability to lyse host bacterial cells specifically thereby helping in disease prevention and control. The requirement of such therapeutic approach is straight away required in view of the global emergence of Multidrug Resistant (MDR) strains of bacteria and rapidly developing resistance to antibiotics in both animals and humans along with increasing food safety concerns including of residual antibiotic toxicities. Phage typing is a popular tool to differentiate bacterial isolates and to identify and characterize outbreak-associated strains of Salmonella, Campylobacter, Escherichia and Listeria. Numerous methods viz. plaque morphology, ultracentrifugation in the density gradient of CsCl2, and random amplified polymorphic DNA (RAPD) have been found to be effective in detection of various phages. Bacteriophages have been isolated and recovered from samples of animal waste products of different livestock farms. High titer cocktails of broad spectrum lytic bacteriophages are usually used for clinical trial for assessing their therapeutic efficacy against antibiotic unresponsive infections in different animals. Bacteriophage therapy also helps to fight various bacterial infections of poultry viz. colibacillosis, salmonellosis and listeriosis. Moreover, the utility of phages concerning biosafety has raised the importance to explore and popularize the therapeutic dimension of this promising novel therapy which forms the topic of discussion of the present review.

    2008-07-01

    There has been research on the use of offline video games for therapeutic purposes but online video game therapy is still fairly under-researched. Online therapeutic interventions have only recently included a gaming component. Hence, this review represents a timely first step toward taking advantage of these recent technological and cultural innovations, particularly for the treatment of special-needs groups such as the young, the elderly and people with various conditions such as ADHD, anxiety and autism spectrum disorders. A review integrating research findings on two technological advances was conducted: the home computer boom of the 1980s, which triggered a flood of research on therapeutic video games for the treatment of various mental health conditions; and the rise of the internet in the 1990s, which caused computers to be seen as conduits for therapeutic interaction rather than replacements for the therapist. We discuss how video games and the internet can now be combined in therapeutic interventions, as attested by a consideration of pioneering studies. Future research into online video game therapy for mental health concerns might focus on two broad types of game: simple society games, which are accessible and enjoyable to players of all ages, and online worlds, which offer a unique opportunity for narrative content and immersive remote interaction with therapists and fellow patients. Both genres might be used for assessment and training purposes, and provide an unlimited platform for social interaction. The mental health community can benefit from more collaborative efforts between therapists and engineers, making such innovations a reality.

    To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18–24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair.

    Aneurysms of the vertebral artery are rare, constituting 0.5 to 3% of all intracranial aneurysms and less than 20% of those of the posterior brain circulation. Bilateral - mirror aneurysms on vertebral artery are extremely rare and unusual lesions, but are often seen and treated in the setting of acute subarachnoid hemorrhage or stroke in the posterior circulation. The treatment of such aneurysms of the vertebral artery with their specific anatomical location is great challenge to traditional neurosurgery.

  11. Implications of technology in music therapy practice and research for music therapy education: a review of literature.

    Science.gov (United States)

    Crowe, Barbara J; Rio, Robin

    2004-01-01

    This article reviews the use of technology in music therapy practice and research for the purpose of providing music therapy educators and clinicians with specific and accurate accounts of the types and benefits of technology being used in various settings. Additionally, this knowledge will help universities comply with National Association of Schools of Music requirements and help to standardize the education and training of music therapists in this rapidly changing area. Information was gathered through a literature review of music therapy and related professional journals and a wide variety of books and personal communications. More data were gathered in a survey requesting information on current use of technology in education and practice. This solicitation was sent to all American Music Therapy Association approved universities and clinical training directors. Technology applications in music therapy are organized according to the following categories: (a) adapted musical instruments, (b) recording technology, (c) electric/electronic musical instruments, (d) computer applications, (e) medical technology, (f) assistive technology for the disabled, and (g) technology-based music/sound healing practices. The literature reviewed covers 177 books and articles from a span of almost 40 years. Recommendations are made for incorporating technology into music therapy course work and for review and revision of AMTA competencies. The need for an all-encompassing clinical survey of the use of technology in current music therapy practice is also identified.

    The goal of this article is to provide consensus recommendations for reporting standards, terminology, and written definitions when reporting on the radiological evaluation and endovascular treatment of intracranial, cerebral aneurysms. These criteria can be used to design clinical trials, to provide uniformity of definitions for appropriate selection and stratification of patients, and to allow analysis and meta-analysis of reported data. This article was written under the auspices of the Joint Writing Group of the Technology Assessment Committee, Society of Neurolnterventional Surgery, Society of Interventional Radiology; Joint Section on Cerebrovascular Neurosurgery of the American Association of Neurological Surgeons and Congress of Neurological Surgeons; and Section of Stroke and Interventional Neurology of the American Academy of Neurology. A computerized search of the National Library of Medicine database of literature (PubMed) from January 1991 to December 2007 was conducted with the goal to identify published endovascular cerebrovascular interventional data about the assessment and endovascular treatment of cerebral aneurysms useful as benchmarks for quality assessment. We sought to identify those risk adjustment variables that affect the likelihood of success and complications. This article offers the rationale for different clinical and technical considerations that may be important during the design of clinical trials for endovascular treatment of cerebral aneurysms.

    Thoracic aortic aneurysms are now routinely repaired with endovascular repair if anatomically feasible because of advantages in safety and recovery. However, intraoperative aneurysm rupture is a severe complication which may have an adverse effect on the outcome of treatment. Comprehensive preoperative assessment and considerate treatment are keys to success of endovascular aneurysm repair, especially during unexpected circumstances. Few cases have reported on intraoperative aortic rupture, which were successfully managed by endovascular treatment. Here, we present a rare case of an intraoperative aneurysm rupture during endovascular repair of thoracic aortic aneurysm with narrow neck and angulated aorta arch (coarctation-associated aneurysm), which was successfully treated using double access route approach and iliac limbs of infrarenal devices.Level of EvidenceLevel 5.

    Megna, Matteo; Fabbrocini, Gabriella; Marasca, Claudio; Monfrecola, Giuseppe

    2017-01-01

    Photodynamic therapy (PDT) is a noninvasive treatment that utilizes light treatment along with application of a photosensitizing agent. In dermatology, PDT is commonly used and approved for the treatment of oncological conditions such as actinic keratosis, Bowen disease and superficial basal cell carcinoma. In the last 2 decades however, PDT has also been used for the treatment of several nonneoplastic dermatological diseases. The present review summarizes published data on PDT application in skin appendage disorders. Our literature review shows that: (a) PDT may be a suitable treatment for acne, folliculitis decalvans, hidradenitis suppurativa, nail diseases, and sebaceous hyperplasia; (b) there is a lack of agreement on PDT features (type, concentrations and incubation period of used substances, number and frequency of PDT sessions, optimal parameters of light sources, and patient characteristics [e.g., failure to previous treatments, disease severity, body surface area involved, etc.] which should guide PDT use in these diseases); (c) further research is needed to establish international guidelines helping dermatologists to choose PDT for the right patient at the right time.

    Full Text Available Jaishree Sharad Skinfiniti Aesthetic Skin and Laser Clinic, Mumbai, India Abstract: Chemical peels have been time-tested and are here to stay. Alpha-hydroxy peels are highly popular in the dermatologist's arsenal of procedures. Glycolic acid peel is the most common alpha-hydroxy acid peel, also known as fruit peel. It is simple, inexpensive, and has no downtime. This review talks about various studies of glycolic acid peels for various indications, such as acne, acne scars, melasma, postinflammatory hyperpigmentation, photoaging, and seborrhea. Combination therapies and treatment procedure are also discussed. Careful review of medical history, examination of the skin, and pre-peel priming of skin are important before every peel. Proper patient selection, peel timing, and neutralization on-time will ensure good results, with no side effects. Depth of the glycolic acid peel depends on the concentration of the acid used, the number of coats applied, and the time for which it is applied. Hence, it can be used as a very superficial peel, or even a medium depth peel. It has been found to be very safe with Fitzpatrick skin types I–IV. All in all, it is a peel that is here to stay.

    Radiation therapy (RT) is effective treatment for curing and palliating cancer, yet concern exists that not all Canadians for whom RT is indicated receive it. Many factors may contribute to suboptimal use of RT. A review of recent Canadian literature was undertaken to identify such barriers. MEDLINE, CINAHL, and EMBase databases were used to search keywords relating to barriers to accessing or utilizing RT in Canada. Collected abstracts were reviewed independently. Barriers identified in relevant articles were categorized as relating to the health systems, patient socio-demographic, patient factors, or provider factors contexts and thematic analysis performed for each context. 535 unique abstracts were collected. 75 met inclusion criteria. 46 (61.3%) addressed multiple themes. The most cited barriers to accessing RT when indicated were patient age (n = 26, 34.7%), distance to treatment centre (n = 23, 30.7%), wait times (n = 22, 29.3%), and lack of physician understanding about the use of RT (n = 16, 21.6%). Barriers to RT are reported in many areas. The role of provider factors and the lack of attention to patient fears and mistrust as potential barriers were unexpected findings demanding further attention. Solutions should be sought to overcome identified barriers facilitating more effective cancer care for Canadians

    To systematically review the published clinical trials, case series, and case reports on left unilateral (LUL) electrode placement for clinical electroconvulsive therapy (ECT). PubMed, Ovid Medline, and the Cochrane Library were searched for articles concerning LUL ECT. Number of patients, efficacy, and cognitive outcomes were extracted from the papers that met our inclusion criteria. A total of 52 articles were included in this review, consisting of 33 clinical trials, seven case series, and 12 case reports. Overall, the efficacy of LUL electrode placement for the treatment of depression and psychosis is similar to that of right unilateral (RUL) and bilateral (BL) electrode placements. Patients receiving LUL ECT tend to experience more verbal memory impairment than patients receiving RUL ECT, but less verbal impairment than patients receiving BL ECT. In contrast, patients receiving LUL ECT tended to experience the least visual and nonverbal memory impairment, compared to patients receiving RUL or BL ECT. © 2017 John Wiley & Sons A/S.

    2010-10-01

    Chronic low back pain is a common condition affecting a significant proportion of the population and has large economic implications on the society. Acupuncture has grown in popularity as an alternative therapy for chronic low back pain. Recent National Institute for Health and Clinical Excellence (NICE) guidelines on low back pain offer a course of acupuncture as a baseline treatment option according to patient preference. The aim of this systematic review was to evaluate if this treatment option is justified in view of recent evidence available on the efficacy of acupuncture. Studies included were identified by a PubMed search for relevant, randomised, controlled trials on the 23 July 2009. A systematic review was performed. Fifteen randomised controlled trials were identified. Of these, four met the eligibility criteria and were critically appraised. These trials suggest acupuncture can be superior to usual care in treating chronic low back pain, especially, when patients have positive expectations about acupuncture. NICE guidelines of a course of acupuncture, offered according to patient preference as a treatment option for chronic low back pain, are justified.

    Right heart failure is associated with increased mortality and morbidity. The optimal treatment for patients with RV failure is not established. The aim of this study is to conduct a systematic review of the literature to assess the relative benefits and harms of digoxin therapy in patients with RV failure. We performed a literature search in MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) on Nov. 4, 2014. We did not use publication type, period or language restrictions to the search strategy. Exclusions included: trials that excluded patients with RV failure, included patients requiring mechanical or intravenous inotropic support, review papers and case reports. The primary outcome was long-term efficacy outcomes of digoxin in right heart failure. Two reviewers screened titles and abstracts of identified citations independently and in duplication using calibration exercises and standardized screening forms. The search strategy identified 4097 citations, and 4 studies were included in this analysis (n=76 patients). Of the four studies, two assessed improvements in RVEF, two studies compared exercise capacity indexes, and one assessed symptoms with digoxin compared with placebo. No study assessed mortality outcomes. Overall, there was no statistically significant improvement in RVEF, exercise capacity, NYHA class, heart failure score, or body weight. There are few studies evaluating Digitalis use for RV failure, which are limited to patients with cor pulmonale. In these patients, Digitalis use provides no improvement in RVEF, exercise capacity, or NYHA class. Randomized clinical trials are needed to address this question.

    2016-01-01

    We sought to conduct a qualitative systematic review to evaluate the safety and efficacy of available treatments for pediatric patients with migraine or benign primary headache in the emergency department, in an effort to inform future practice. Scopus, Medline, and PubMed databases were searched for randomized controlled trials retrospective reviews, review articles, and case studies discussing migraine or benign primary headache management that were conducted in the emergency room or outpatient acute care setting in pediatric patients (less than 18-years old). Meeting abstracts and cited references within articles were also evaluated. Multiple variables were recorded, including type of treatment, study design, dosing, primary outcome, and side effects. Therapeutic gain was calculated in studies with a placebo arm. Treatments were subjectively assessed based on methodology and number of trials for a particular therapy. Thirty-one studies were included in the final analysis. Of these, 17 were randomized controlled trials, 9 were retrospective reviews, and 5 were prospective chart review studies. One pertained to IV fluids, 2 to nonspecific analgesic use, 5 to dopamine receptor antagonists, 2 to valproic acid, 1 to propofol, 1 to magnesium, 1 to bupivicaine, 13 to triptan medications, and 3 to dihydroergotamine (DHE). Treatments considered effective for acute migraine or benign primary headache in the analgesic category include ibuprofen, and to a lesser degree acetaminophen. Ketorolac was not compared to other NSAIDs, but was found to be less effective than prochlorperazine. Of the phenothiazines, prochlorperazine was considered most effective. Of the triptan medications, almotriptan, rizatriptan, zolmitriptan nasal spray, sumatriptan nasal spray, and combination sumatriptan/naproxen are effective agents for acute treatment. Treatments considered probably effective included IV fluids, chlorpromazine, valproate sodium, injectable sumatriptan, and IV DHE. Treatments

    Endovascular stent graft placement has become a major treatment for thoracic and abdominal aneurysms. While endovascular therapy is less invasive than open surgery, it involves the use of a contrast medium. Contrast media can cause renal impairment, a condition termed as contrast-induced nephropathy (CIN). This study sought to evaluate the incidence and risk factors of CIN following endovascular stent graft placement for aortic aneurysm repair. The study included 167 consecutive patients who underwent endovascular stent graft placement in our hospital from October 2013 to June 2014. CIN was diagnosed using the European Society of Urogenital Radiology criteria. Patients with and without CIN were compared. Chi-squared tests, t-tests, and multivariate logistic regression analyses were performed. Thirteen patients (7.8%) developed CIN. Left ventricular dysfunction and intraoperative blood transfusion were significantly more frequent in the CIN group (P = 0.017 and P = 0.032, resp.). Multivariate analysis showed that left ventricular dysfunction had the strongest influence on CIN development (odds ratio 9.34, P = 0.018, and 95% CI = 1.46–59.7). Patients with CIN also experienced longer ICU and hospital stays. Measures to improve renal perfusion flow should be considered for patients with left ventricular dysfunction who are undergoing endovascular stent graft placement

    2017-01-01

    Full Text Available Treatment of thoracic aortic aneurysms constitutes high mortality and morbidity rates despite improvements in surgery, anesthesia, and technology. Endovascular stent grafting may be an alternative therapy with lower risks when compared with conventional techniques. However, sometimes the branches of the aortic arch may require transport to the proximal segments prior to successful thoracic aortic endovascular stent grafting. Atherosclerosis is accounted among the etiology of both aneurysms and occlusive diseases that can coexist in the same patient. In these situations stent grafting may even be more complicated. In this report, we present the treatment of a 92-year-old patient with aortic arch aneurysm and proximal descending aortic aneurysm. For successful thoracic endovascular stent grafting, the patient needed an alternative route other than the native femoral and iliac arteries for the deployment of the stent graft. In addition, debranching of left carotid and subclavian arteries from the aortic arch was also required for successful exclusion of the thoracic aneurysm.

    2015-12-01

    Electroconvulsive therapy (ECT) can raise feelings of fear and anxiety in our patients. No documented cases of phobia regarding ECT or its treatment were found in the literature. We present a patient who developed anxiety regarding ECT that was severe enough to be classified as a phobia. She was successfully treated with cognitive behavioral therapy (CBT) for her phobia and was subsequently able to tolerate ECT. We conducted a literature review of ECT phobia, fear, and anxiety using MEDLINE, PsycINFO, and EMBASE. We outlined how CBT, in our specific case, was helpful in treating extreme and unrealistic fears concerning ECT. We could not find a case of phobia related to ECT in the literature; however, both qualitative and quantitative studies illustrate that ECT causes anxiety and fear. Although cases of ECT phobia are rare, feelings of fear and anxiety surrounding ECT are common. The experience of ECT is individualized for each patient, and CBT can be a successful treatment in those who have anxiety related to ECT.

    Nutcracker syndrome is a rare entity, and in the majority of cases is the result of extrinsic compression of the left renal vein between the superior mesenteric artery and the aorta, associated with functional stenosis. To present the case of a 19-year-old female with no significant medical history with confirmed diagnosed of nutcracker syndrome treated successfully by endovascular means. She was referred to the Vascular Surgery Department with a 6-month history of macroscopic haematuria, after other aetiologies were ruled out. Abdominal computed tomography angiography revealed compression of the left renal vein; the patient underwent endovascular treatment, and a 12×16 mm balloon expandable stent was placed with immediate angiographic improvement, decreased pressure gradients and progressive resolution of haematuria. At one year, she remains symptom-free. Nutcracker syndrome is uncommon, and a high index of suspicion is needed. Macroscopic haematuria is not always present, and in our case stent placement demonstrated effectiveness in the resolution of symptoms at 12 months' follow--up. We also present a brief review of the literature. Copyright © 2016 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A. All rights reserved.

    Electroconvulsive therapy (ECT) is associated with at least transient episodes of hypertension and tachycardia. Beta-blocking agents may be indicated to prevent cardiovascular complications and may shorten seizure duration. This review evaluates studies that used beta-blocking agents during ECT to determine which agent has the most favourable outcomes on cardiovascular variables and seizure duration. A Medline database search was made using the combined keywords 'adrenergic beta-antagonists' and 'electroconvulsive therapy'. The search was restricted to double-blind randomized controlled trials and yielded 29 original studies. With the use of esmolol, significant attenuating effects were found on cardiovascular parameters in the first 5 min after stimulation; its shortening effects on seizure duration may be dose-related. With the use of labetalol, findings on cardiovascular effects were inconsistent during the first minutes after stimulation but were significant after 5 min and thereafter; seizure duration was scarcely studied. Landiolol attenuates heart rate but with inconsistent findings regarding arterial pressure (AP); seizure duration was mostly unaffected. Esmolol appears to be effective in reducing the cardiovascular response, although seizure duration may be affected with higher dosages. Landiolol can be considered a suitable alternative, but effects on AP need further investigation. Labetalol has been studied to a lesser extent and may have prolonged cardiovascular effects. The included studies varied in design, methodology, and the amount of exact data provided in the publications. Further study of beta-blocking agents in ECT is clearly necessary. © The Author [2014].

    Art therapy has often been applied in the treatment of traumatized adults, and good results in clinical practice have been reported. However, although art therapy experts underline these benefits, the effectiveness of art therapy in trauma treatment has not been established by systematic review. The aim of this systematic review is to identify and evaluate empirical evidence of the effectiveness of art therapy for trauma treatment. As a result of the systematic review, six controlled, comparative studies on art therapy for trauma in adult patients were found. In half of the included studies, a significant decrease in psychological trauma symptoms was found in the treatment groups, and one study reported a significant decrease in depression. Although there are limitations in the number of included studies, the number of participants, the heterogeneity of included studies, and their methodological quality, the results contribute to insight into the effectiveness of art therapy in trauma treatment and form an evidence base for the urgent need for further research on art therapy and trauma treatment. © The Author(s) 2014.

    Multiple sclerosis (MS) is an incurable neurological illness that frequently causes chronic disability. Neurologists broach the diagnosis with dread. "I'll end up in a wheel chair" is the anguished cry of the newly diagnosed and mostly young patients. The past decade has improved our understanding of the immunopathogenesis of MS enormously. This has led to a plethora of clinical trials and the resultant emergence of several new drugs in various stages of development. In 1993, Food and Drug Administration (FDA) approved Betaseron for the treatment of MS. Todate, this is the only drug approved by the FDA, specifically for the treatment of MS. However, it would not be too long before several other drugs are approved, leaving the neurologist bewildered having gone from a state of practically little to offer to a state of several options to choose from. This review discusses the status of current and future therapy in the treatment of MS. Multiple sclerosis (MS) is the most common demyelinating disease of the human central nervous system (CNS). Medline includes over 13000 articles on MS since 1966 that exclude book chapters and other references. MS typically affects the youth and women more than men, between the ages of twenty and forty. Clinically, the illness is characterized into a relapsing-remitting (RR) or chronic progressive (CP) stage although more precisely defined stages exist for research purposes. It tends to follow a highly unpredictable course leading to chronic and sometimes devastating disability. More recently, follow up data suggested that the disease may fall into a pattern after several years. Despite decades of hectic research and better understanding of immunological mechanisms involving human CNS disease, the cause of MS remains unknown. However, it is widely believed that MS is the result of an autoimmune disorder in a genetically susceptible individual, mediated by autoreactive T cells that migrate into the CNS and initiate the inflammatory

    PurposeTo report a single centre’s experience of the endovascular treatment of renal arterial aneurysms, including techniques and outcomes.Materials and MethodsThis is a retrospective analysis of true renal arterial aneurysms (TRAAs) treated using endovascular techniques over a period of 12 years and 10 months. The clinical presentations, aneurysm characteristics, endovascular techniques and outcomes are reported.ResultsThere were nine TRAA cases with a mean aneurysm size of 21.0 mm, located at the main renal arterial bifurcation in all cases. Onyx{sup ®} was used as the embolic agent of choice (88.9 % cases), with concurrent balloon remodelling. The overall primary technical success rate was 100 %. Repeat intervention was carried out in 1 case, secondary to reperfusion >8 years post-initial treatment. Long-term clinical follow-up was available in 55.6 % of cases (mean 29.8 months; range 3.3–90.1 months). Early post-procedural renal function, as measured by serum creatinine, remained within the normal reference range. Renal parenchymal loss post-embolisation was ≤20 % in 77.8 % of cases, as estimated on imaging. Minor complications included non-target embolization of Onyx{sup ®} with no clinical sequelae (n = 1), transient pain requiring only oral analgesia with no prolongation of hospital stay (n = 2). No major complications occurred as a consequence of embolisation.ConclusionEndovascular therapy is an effective and safe primary therapy for TRAA with high success rate and low morbidity, supplanting surgery as primary therapy. Current experience in the use of Onyx{sup ®} in TRAA is primarily limited to individual case reports, and this represents the largest case series of Onyx{sup ®}-treated TRAAs to date.

    In response to global trends of maximizing the number of patients receiving antiretroviral therapy (ART), this review summarizes literature describing differentiated models of ART distribution at facility and community levels in order to highlight promising strategies and identify evidence gaps. Databases and gray literature were searched, yielding thirteen final articles on differentiated ART distribution models supporting stable adult patients. Of these, seven articles focused on distribution at facility level and six at community level. Findings suggest that differentiated models of ART distribution contribute to higher retention, lower attrition, and less loss to follow-up (LTFU). These models also reduced patient wait time, travel costs, and time lost from work for drug pick-up. Facility- and community-level ART distribution models have the potential to extend treatment availability, enable improved access and adherence among people living with HIV (PLHIV), and facilitate retention in treatment and care. Gaps remain in understanding the desirability of these models for PLHIV, and the need for more information the negative and positive impacts of stigma, and identifying models to reach traditionally marginalized groups such as key populations and youth. Replicating differentiated care so efforts can reach more PLHIV will be critical to scaling these approaches across varying contexts.

    Healing of the extraction socket after tooth removal involves retention of the blood clot followed by a sequence of events that lead to changes in the alveolar process in a three dimensional fashion. This normal healing event results in a minimal loss of vertical height (around 1 mm), but a substantial loss of width in the buccal-lingual plane (4-6 mm). During the first three months following extraction that loss has been shown to be significant and may result in both a hard tissue and soft tissue deformity affecting the ability to restore the site with acceptable esthetics. Procedures that reduce the resorptive process have been shown to be predictable and potentially capable of eliminating secondary surgery for site preparation when implant therapy is planned. The key element is prior planning by the dental therapist to act at the time of extraction to prevent the collapse of the ridge due to the loss of the alveolus. Several techniques have been employed as ridge preservation procedures involving the use of bone grafts, barrier membranes and biologics to provide a better restorative outcome. This review will explore the evidence behind each technique and their efficacy in accomplishing site preparation. The literature does not identify a single technique as superior to others; however, all accepted therapeutic procedures for ridge preservation have been shown to be more effective than blood clot alone in randomized controlled studies.

    Nanotechnology is an up-and-coming branch of science that studies and designs materials with at least one dimension sized from 1-100 nm. These nanomaterials have unique functions at the cellular, atomic, and molecular levels. The term "nanotechnology" was first coined in 1974. Since then, it has evolved dramatically and now consists of distinct and independent scientific fields. Nanotechnology is a highly studied topic of interest, as nanoparticles can be applied to various fields ranging from medicine and pharmacology, to chemistry and agriculture, to environmental science and consumer goods. The rapidly evolving field of nanomedicine incorporates nanotechnology with medical applications, seeking to give rise to new diagnostic means, treatments, and tools. Over the past two decades, numerous studies that underscore the successful fusion of nanotechnology with novel medical applications have emerged. This has given rise to promising new therapies for a variety of diseases, especially cancer. It is becoming abundantly clear that nanotechnology has found a place in the medical field by providing new and more efficient ways to deliver treatment. Ophthalmology can also stand to benefit significantly from the advances in nanotechnology research. As it relates to the eye, research in the nanomedicine field has been particularly focused on developing various treatments to prevent and/or reduce corneal neovascularization among other ophthalmologic disorders. This review article aims to provide an overview of corneal neovascularization, currently available treatments, and where nanotechnology comes into play.

    The objective of this study was to identify factors predicting the need for reintervention after endovascular repair of isolated iliac artery aneurysm (IIAA). We reviewed prospectively collected database records of all patients who underwent endovascular repair of IIAA between 1999 and 2008. Detailed assessment of the aneurysms was performed using computed tomography angiography (CTA). Follow-up protocol included CTA at 3 months. If this showed no complication, then annual duplex scan was arranged. Multivariate analysis and analysis of patient survival and freedom from reintervention were performed using Kaplan–Meier life tables. Forty IIAAs (median diameter 44 mm) in 38 patients were treated (all men; median age 75 years), and median follow-up was 27 months. Endovascular repair of IIAA was required in 14 of 40 aneurysms (35%). The rate of type I endoleak was significantly higher with proximal landing zone (PLZ) diameter >30 mm in the aorta or >24 mm in the common iliac artery or distal landing zone (DLZ) diameter >24 mm (P = 0.03, 0.03, and 0.0014, respectively). Reintervention rate (RR) increased significantly with increased diameter or decreased length of PLZ; increased DLZ diameter; and endovascular IIAA repair (P = 0.005, 0.005, 0.02, and 0.02 respectively); however, RR was not significantly affected by length of PLZ or DLZ. Freedom-from-reintervention was 97, 93, and 86% at 12, 24, and 108 months. There was no in-hospital or aneurysm-related mortality. Endovascular IIAA repair is a safe treatment option. Proper patient selection is essential to decrease the RR.

    The aim of this study was to assess clinical and contemporary costs associated with elective endovascular repair of intact descending thoracic aortic aneurysms (DTAA) into the mid-term follow-up. A retrospective review of a prospectively maintained clinical database including 29 consecutive patients from July 2005 to December 2009 treated with elective endovascular repair (TEVAR) or TEVAR and surgical infrarenal repair (hybrid) of intact DTAA was performed. Mean age was 74.5 years old (±7.1). Primary clinical endpoints include mortality and major morbidity. Additionally a comprehensive economic appraisal of individual in-hospital and follow-up costs was executed. Economic endpoints include in-hospital and follow-up costs and patient discharge status. Elective endovascular and open repairs' clinical and economical outcomes in contemporary literature were assessed for comparison according to PRISMA standards. Immediate mortality was 6.9% (1/24 TEVAR and 1/5 hybrid). Three respiratory complications were recorded (11%; 2 TEVAR, 1 hybrid). Renal and cardiac complication rates were 7.4% (1 TEVAR, 1 hybrid) and 3.7% (1 TEVAR) respectively. Routine discharge home was achieved for 85% of patients (95.7% TEVAR, 25% hybrid). Three endoleaks were treated throughout the follow-up (2 TEVAR, 1 hybrid; mean 30.4 mo, ±19.9) rendering an 11% (3/27) reintervention rate. Average immediate cost was €21,976.87 for elective endovascular repair and €33,783.21 for elective endovascular hybrid repair. Additional reintervention and routine follow-up costs augmented immediate costs by 12.4%. This study supports satisfying immediate clinical outcomes for TEVAR and TEVAR+surgical infrarenal procedures. Although limited by a small population size and difficulties in economic comparisons, this study presents the real world social and economic cost scenario for both elective TEVAR and TEVAR hybrid treatment of DTAA of both the in-hospital and at mid term follow-up periods.

    The management paradigm for traumatic aortic disruptions has evolved from open to endovascular repair. Thoracic stent grafts designed to treat aneurysmal disease, however, have disadvantages, including size mismatch in younger trauma patients and current standard lengths, which may needlessly necessitate coverage of at least 10 cm of thoracic aorta, increasing the risk of spinal cord ischemia. The "off-label" use of abdominal aortic extension cuffs to treat traumatic aortic disruptions may provide an advantage in this regard by better size matching for the younger trauma patient, reduced thoracic aortic coverage, and less cost to the institution. From 2008 to 2011, a total of 16 traumatic aortic disruptions were evaluated and managed with endovascular techniques. The last six were treated with abdominal aortic extensions cuffs (Excluder Extension Cuffs; W.L. Gore & Associates, Flagstaff, AZ) rather than traditional thoracic stent grafts. In addition to demographics and trauma-related data, additional endpoints evaluated in this retrospective review included operative time, number of cuffs used, stent cost data, procedural complications, and follow-up. All six patients (five men/one woman) with traumatic aortic disruption were successfully treated with complete exclusion of the disruption using abdominal aortic cuffs. There were no complications including death or spinal cord ischemia. The average age was 27 years (range, 18-44 years). The average number of cuffs used to cover the traumatic tear was 2.6 per patient (range, 2-3 cuffs per patient), covering an average of 5.3 cm of thoracic aorta (range, 4-6 cm). Mean procedure time was 70 minutes. Hospital cost for each cuff was $2200 (average total stent cost per patient, $5720). For comparison, a single 10-cm conformable thoracic aortic graft (CTAG) (Gore) costs $14,500. Average follow-up of all six patients for up to 3 years demonstrates no complications or migration of the stent grafts. Traumatic aortic

    We report our experience and the midterm results of a modern technique for endovascular management of isolated iliac artery aneurysms (IAAs) with unfavorable neck anatomy, which involves the inversion of an iliac leg of a Zenith stent graft. Patients who underwent endovascular IAA repair from 2002 to 2010 were reviewed. A total of 12 patients, with a mean age of 77.6 years, underwent endovascular repair of 13 IAAs. Mean size of the aneurysms was 54.6 mm (range 34-133 mm). Mean proximal neck diameter was 18 mm (range 15-22 mm). In 7 patients, the length of the proximal neck was <15 mm (10-14 mm). Only 1 patient developed thrombosis of the stent graft immediately after the operation. Patients were followed up for a mean of 31.5 months (range 18-72 months). Our midterm results demonstrate the durability of this technique in the management of iliac aneurysms with unfavorable anatomy.

  9. A review of rotating gantries for heavy charged particle therapy

    Heidelberg clinic. A pair of scanning magnets is placed before the last bending magnet to decrease the length of the straight section. The characteristics of the gantry beam optics lies in the fact that the incident beam is rotated in the reference frame of the gantry when the gantry rotates. This results in the variation of beam shape if the beam emittances in x and y-axes are different in general. This should be considered carefully to control the beam size at the patient position as in the case of beam scanning. Since the gantry structure has a mechanical distortion depending on the rotation angle, beam misalignment could occur due to the misalignment of gantry magnets. If precise beam alignment is required for the beam delivery system, beam steering should be made by a pair of the steering magnets to correct the shift of the beam centroid. Since we observe some hysteresis of beam centroid shift depending on the direction of rotation in some cases, we should be careful for locating the gantry at some specified angle with a pre-defined trajectory of rotation. We will review the proton gantries manufactured so far and a number of new proposed design and study the future prospect of rotating gantries for heavy charged particle therapy. (author)

    Our aim was to analyze the outcomes of endovascular exclusion of the entire aortic arch (proximal landing in zone 0, distal landing in zone III or beyond, after Ishimaru) in which complete surgical debranching of the supra-aortic vessels (I), endovascular supra-aortic revascularization (chimney, fenestrated, or branched grafts) with partial surgical debranching (II), or total endovascular supra-aortic revascularization (III) was additionally performed. Publications describing endovascular repair of the aortic arch (2000-2016) were systematically searched and reviewed. From a total of 53 relevant studies including 1853 patients, only 1021 patients undergoing 35 different total aortic arch procedures were found eligible for further evaluation and included in group I, II, or III (429, 190, and 402 patients, respectively). Overall early mortality was higher in group I vs groups II and III (P = .001; 1 - β = 95.6%) but exceeded in group III (18.6%) and group II (14.0%) vs group I (8.0%; P = .044; 1 - β = 57.4%) for diseases involving zone 0. Mortality was higher in all subgroups treated for zone 0 disease compared with corresponding subgroups treated for zone I to zone III disease. The incidence of cerebral ischemic events was increased in groups I and II vs group III (7.5% and 11% vs 1.7%; P = .0001) and correlated with early mortality (R 2  = .20; P = .033). The incidence of type II endoleaks and endovascular reintervention was similar between groups and correlated with each other (R 2  = .37; P = .004). Type Ia endoleak occurred more often in groups II and III than in group I (7.1% and 12.1% vs 5.8%; P = .023) and correlated with midterm mortality (R 2  = .53; P = .005). Retrograde type A dissection was low in all groups, whereas aneurysm growth was higher in group III (2.6%, 4.2%, 10.7%; P = .002), correlating with midterm mortality (R 2  = .311; P = .009). Surgical revision slightly correlated with surgical complications (R 2  = .18; P = .044

    Selective mutism (SM) is a debilitating childhood anxiety disorder characterized by a persistent lack of speech in certain social settings and is considered hard to treat. Cognitive behavioral therapy (CBT) and pharmacological treatments are the best described treatments in the literature. To test whether there is evidence on treatment based on CBT, medication or a combination of these. Systematic and critical review of the literature on CBT and/or pharmacological treatments of SM. Literature was sought on PubMed, Embase and Psycinfo in March 2017. Of the included studies, six examined CBT, seven pharmacologic treatment and two a combination of these. Using CBT 53/60 children improved symptomatically whilst respectively 55/67 and 6/7 improved using pharmacologic- and combination-treatment. Pharmacologic treatment and especially CBT showed promising results supported by some degree of evidence, which combination treatment lacks. Yet small numbers, few RCTs, heterogeneous study designs, lack of consistent measures, short treatment and follow-up periods, generally limits the evidence. This needs focus in future research.

  12. A review of immune therapy in cancer and a question: can thermal therapy increase tumor response?

    Science.gov (United States)

    Bull, Joan M C

    2017-11-03

    Immune therapy is a successful cancer treatment coming into its own. This is because checkpoint molecules, adoptive specific lymphocyte transfer and chimeric antigen T-cell (CAR-T) therapy are able to induce more durable responses in an increasing number of malignancies compared to chemotherapy. In addition, immune therapies are able to treat bulky disease, whereas standard cytotoxic therapies cannot treat large tumour burdens. Checkpoint inhibitor monoclonal antibodies are becoming widely used in the clinic and although more complex, adoptive lymphocyte transfer and CAR-T therapies show promise. We are learning that there are nuances to predicting the successful use of the checkpoint inhibitors as well as to specific-antigen adoptive and CAR-T therapies. We are also newly aware of a here-to-fore unrealised natural force, the status of the microbiome. However, despite better understanding of mechanisms of action of the new immune therapies, the best responses to the new immune therapies remain 20-30%. Likely the best way to improve this somewhat low response rate for patients is to increase the patient's own immune response. Thermal therapy is a way to do this. All forms of thermal therapy, from fever-range systemic thermal therapy, to high-temperature HIFU and even cryotherapy improve the immune response pre-clinically. It is time to test the immune therapies with thermal therapy in vivo to test for optimal timing of the combinations that will best enhance tumour response and then to begin to test the immune therapies with thermal therapy in the clinic as soon as possible.

    2017-09-01

    Full Text Available Background: There are several established, and an increasing number of putative, therapies using sound to treat tinnitus. There appear to be few guidelines for sound therapy selection and application.Aim: To review current approaches to personalizing sound therapy for tinnitus.Methods: A “state-of-the-art” review (Grant and Booth, 2009 was undertaken to answer the question: how do current sound-based therapies for tinnitus adjust for tinnitus heterogeneity? Scopus, Google Scholar, Embase and PubMed were searched for the 10-year period 2006–2016. The search strategy used the following key words: “tinnitus” AND “sound” AND “therapy” AND “guidelines” OR “personalized” OR “customized” OR “individual” OR “questionnaire” OR “selection.” The results of the review were cataloged and organized into themes.Results: In total 165 articles were reviewed in full, 83 contained sufficient details to contribute to answering the study question. The key themes identified were hearing compensation, pitched-match therapy, maskability, reaction to sound and psychosocial factors. Although many therapies mentioned customization, few could be classified as being personalized. Several psychoacoustic and questionnaire-based methods for assisting treatment selection were identified.Conclusions: Assessment methods are available to assist clinicians to personalize sound-therapy and empower patients to be active in therapy decision-making. Most current therapies are modified using only one characteristic of the individual and/or their tinnitus.

    Life review therapy is recognized as an evidence-based treatment for depression in later life. The current article evaluates an online life review therapy in middle-aged and older persons, comparing a counselor-led to a peer-supported mode of delivery. A pilot randomized controlled trial (RCT) was carried out with 3 conditions and 4 measurement points: (a) online life review therapy with online counseling, (b) online life review therapy with online peer support, and (c) a waitlist control condition. A mixed methods study provided insight in the reach, adherence, effectiveness, user experiences, and acceptability. Fifty-eight people were included in the study. The intervention reached a vulnerable group of mainly middle-aged, college-educated women. The pilot RCT on effectiveness showed that participants in all conditions improved significantly in depressive symptoms, engaged living, mastery, and vitality, but not in ego integrity and despair, social support, loneliness, and well-being. The adherence, user experience, and acceptability were better in the counselor condition than in the peer condition. No differences were found between middle-aged and older adults. Despite the nonsignificant effects, possibly due to the small sample size, online life review therapy might be a good method for alleviating depressive symptoms in people in their second half of life. Further research is needed, addressing how online life review is best offered. © The Author 2017. Published by Oxford University Press on behalf of The Gerontological Society of America.

    Background Vaginal dilator (VD) therapy is often recommended for women receiving pelvic radiation therapy or experiencing pain and discomfort during intercourse, as well as for women with a congenital malformation of the vagina. VD use has both physical and psychological benefits; however, it often causes pain, discomfort, and adverse emotions, including embarrassment and loss of modesty, which often result in low adherence to therapy. Objectives The aims of this study were to explore the use and adherence of VD therapy in women, identify barriers and facilitators of therapy adherence, and suggest improvement strategies from the theoretical perspective of symbolic interactionism. Methods A systematic review of the literature was conducted using PubMed, CINAHL, and Scopus databases, with no year restrictions. Articles addressing the experience of women using VD therapy, as well as barriers and facilitators of therapy adherence were selected and analyzed. Then, the theoretical perspective of symbolic interactionism was introduced and applied to synthesize the results. Results A total of 21 articles were selected for the review. Most of the reviewed studies explored VD therapy in women who had undergone pelvic radiation therapy for gynecological cancer. Women’s adherence to the therapy ranged between 25% and 89.2%, with great variance in definitions and methods for assessing therapy adherence. Among the five categories of identified barriers to therapy adherence, “unhelpful circumstances” and “negative perceptions toward the VD” were the two most frequently mentioned. The two most frequently reported facilitators of adherence among the six identified categories were “supportive interactions with health care providers” and “risk perception and positive outcome expectancies”. On the basis of the perspective of symbolic interactionism, strategies for strengthening interactions with others (eg, health care providers, significant others, and support

The two most frequently reported facilitators of adherence among the six identified categories were "supportive interactions with health care providers" and "risk perception and positive outcome expectancies". On the basis of the perspective of symbolic interactionism, strategies for strengthening interactions with others (eg, health care providers, significant others, and support groups) are discussed in detail.

    Full Text Available Pamela E Houghton School of Physical Therapy, Faculty of Health Sciences, Western University, London, ON, Canada Purpose: The overall objective of this study is to identify and appraise all of the existing clinical research literature that has evaluated the effect of electrical stimulation therapy (EST on wound healing outcomes in adults with various types of chronic wounds. Methods: A systematic and comprehensive search of four electronic databases and gray literature was carried out, and references included in related review articles were checked. Prospective and controlled clinical trials, systematic reviews (SRs, and meta-analyses that assessed the effects of EST on wound healing outcomes were described and appraised. A total PRISMA score was assigned for each included SR based on criteria included in the assessment of multiple systematic reviews (AMSTAR measurement tool. The percentage of available research that was identified in the SR was also calculated. Results: Sixty-two clinical research studies involving 2082 patients with pressure ulcers, venous leg ulcers, diabetic foot wounds, and arterial/ischemic wounds, and ulcers of mixed etiology were located. Thirty-three of the studies with 1370 patients compared wound size reduction after EST to a control group. Eighteen reviews that used a systematic approach to identify, select, and evaluate published studies on this topic have yielded conflicting results. Poorer quality SRs with a low total PRISMA score were more likely to yield negative or inconclusive findings. Most of these low-quality SRs had very vague research questions and included less than 50% of the available literature that was known to exist. Results from 22 well-designed randomized clinical trials and 10 high-quality SRs consistently support that EST can stimulate faster wound size reduction and/or produce a greater number of closed wounds compared to a group of similar patients receiving either standard wound care or sham

    Advances in superselective microcatheterization techniques, which took place in the past decade, established superselective endovascular exploration as an integral and indispensable tool in the pretherapeutic evaluation of brain AVMs. The strict and routine application of superselective angiography furthered our knowledge on the angioarchitecture of brain AVMs, including vascular composition of the nidus, types of feeding arteries and types and patterns of venous drainage. In addition, various types of weak angioarchitectural elements, such as flow-related aneurysms, intranidal vascular cavities and varix formation proximal to high-grade stenosis of draining veins, could be identified as factors predisposing for AVM rupture. A wide spectrum of secondary angiomorphological changes induced by the arteriovenous shunt of the nidus and occurring up- and downstream of the nidus have been identified as manifestations of high-flow angiopathy. These data help to better predict the natural history, understand the widely variable clinical presentation and to define therapeutic targets of brain AVMs. Correlation of the topography of the AVM as demonstrated by MR with the angioarchitecture as demonstrated by superselective angiography provided a system for topographic-vascular classification of brain AVMs, which proved very useful for patient selection and definition of therapeutic goals. This study showed, that 40% of patients with brain AVMs can be cured by embolization alone with a severe morbidity of 1.3% and a mortality of 1.3%. Part of theses patients can, however, be cured equally effective by microsurgery or radiosurgery. Which modality will be chosen for a particular patient will mainly depend on the locally available expertise and experience, but also on the preference of the patient following its comprehensive information about the chances for cure and the risks associated with each of these therapeutic modalities. Embolization has a significant role in the

    The purpose of this study was to characterize the outcome of attempted endovascular intervention in patients with acute embolic or thrombotic superior mesenteric artery (SMA) occlusion. The records of 21 patients during a 3-year period between 2005 and 2008 were retrieved from the in-hospital registry. The first group included 10 patients (6 women and 4 men; median age 78 years) with acute embolic occlusion of the SMA. The median duration of symptoms from symptom onset to angiography was 30 hours (range 6 to 120). Synchronous emboli (n = 12) occurred in 6 patients. Embolus aspiration was performed in 9 patients, and 7 of these had satisfactory results. Complementary local thrombolysis was successful in 2 of 3 patients. Residual emboli were present at completion angiography in all 7 patients who underwent successful aspiration embolectomy, and bowel resection was necessary in only 1 of these patients. One serious complication occurred because of a long SMA dissection. The in-hospital survival rate was 90% (9 of 10 patients). The second group included 11 patients (10 women and 1 man; median age 68 years) with atherosclerotic acute SMA occlusions. The median time of symptom duration before intervention was 97 hours (range 17 to 384). The brachial, femoral, and SMA routes were used in 6, 7, and 5 patients, respectively. SMA stenting was performed through an antegrade (n = 7) or retrograde (n = 3) approach. Bowel resection was necessary in 4 patients. No major complications occurred. The in-hospital survival rate was 82% (9 of 11 patients). Endovascular therapy of acute SMA occlusion provides a good alternative to open surgery.

    Music is known to affect the human mind and body. Music therapy utilizes the effects of music for medical purposes. The history of music therapy is quite long, but only limited evidence supports its usefulness in the treatment of higher cognitive dysfunction. As for dementia, some studies conclude that music therapy is effective for preventing cognitive deterioration and the occurrence of behavioral and psychological symptoms of dementia (BPSD). In patients receiving music therapy for the treatment of higher cognitive dysfunction, aphasia was reported as the most common symptom. Many studies have been conducted to determine whether singing can improve aphasic symptoms: singing familiar and/or unfamiliar songs did not show any positive effect on aphasia. Melodic intonation therapy (MIT) is a method that utilizes melody and rhythm to improve speech output. MIT is a method that is known to have positive effects on aphasic patients. Some studies of music therapy for patients with unilateral spatial neglect; apraxia; hemiparesis; and walking disturbances, including parkinsonian gait, are available in the literature. Studies showed that the symptoms of unilateral spatial neglect and hemiparesis significantly improved when musical instruments were played for several months as a part of the music therapy. Here, I describe my study in which mental singing showed a positive effect on parkinsonian gait. Music is interesting, and every patient can go through training without any pain. Future studies need to be conducted to establish evidence of the positive effects of music therapy on neurological and neuropsychological symptoms.

    Major vascular complications related to pancreatitis can cause life-threatening hemorrhage and have to be dealt with as an emergency, utilizing a multidisciplinary approach of angiography, endoscopy or surgery. These may occur secondary to direct vascular injuries, which result in the formation of splanchnic pseudoaneurysms, gastrointestinal etiologies such as peptic ulcer disease and gastroesophageal varices, and post-operative bleeding related to pancreatic surgery. In this review article, we discuss the pathophysiologic mechanisms, diagnostic modalities, and treatment of pancreatic vascular complications, with a focus on the role of minimally-invasive interventional therapies such as angioembolization, endovascular stenting, and ultrasound-guided percutaneous thrombin injection in their management.

    Guidelines recommend that patients' values and preferences should be considered when selecting stroke prevention therapy for atrial fibrillation (SPAF). However, doing so is difficult, and tools to assist clinicians are sparse. We performed a narrative systematic review to provide clinicians with insights into the values and preferences of AF patients for SPAF antithrombotic therapy. Narrative systematic review of published literature from database inception. 1) What are patients' AF and SPAF therapy values and preferences? 2) How are SPAF therapy values and preferences affected by patient factors? 3) How does conveying risk information affect SPAF therapy preferences? and 4) What is known about patient values and preferences regarding novel oral anticoagulants (NOACs) for SPAF? Twenty-five studies were included. Overall study quality was moderate. Severe stroke was associated with the greatest disutility among AF outcomes and most patients value the stroke prevention efficacy of therapy more than other attributes. Utilities, values, and preferences about other outcomes and attributes of therapy are heterogeneous and unpredictable. Patients' therapy preferences usually align with their values when individualised risk information is presented, although divergence from this is common. Patients value the attributes of NOACs but frequently do not prefer NOACs over warfarin when all therapy-related attributes are considered. In conclusion, patients' values and preferences for SPAF antithrombotic therapy are heterogeneous and there is no substitute for directly clarifying patients' individual values and preferences. Research using choice modelling and tools to help clinicians and patients clarify their SPAF therapy values and preferences are needed.

  6. Effectiveness of Occupational Therapy Interventions for Lower-Extremity Musculoskeletal Disorders: A Systematic Review.

    Dorsey, Julie; Bradshaw, Michelle

    Lower-extremity (LE) musculoskeletal disorders (MSDs) can have a major impact on the ability to carry out daily activities. The effectiveness of interventions must be examined to enable occupational therapy practitioners to deliver the most appropriate services. This systematic review examined the literature published between 1995 and July 2014 that investigated the effectiveness of occupational therapy interventions for LE MSDs. Forty-three articles met the criteria and were reviewed. Occupational therapy interventions varied on the basis of population subgroup: hip fracture, LE joint replacement, LE amputation or limb loss, and nonsurgical osteoarthritis and pain. The results indicate an overall strong role for occupational therapy in treating clients with LE MSDs. Activity pacing is an effective intervention for nonsurgical LE MSDs, and multidisciplinary rehabilitation is effective for LE joint replacement and amputation. Further research on specific occupational therapy interventions in this important area is needed. Copyright © 2017 by the American Occupational Therapy Association, Inc.

    An abnormal dilatation of the abdominal aorta is referred to as an abdominal aortic aneurysm (AAA). Due to the risk of rupture, surgical repair is offered electively to individuals with aneurysms greater than 5.5 cm in size. Traditionally, conventional open surgical repair (OSR) was considered the first choice approach. However, over the past two decades endovascular aneurysm repair (EVAR) has gained popularity as a treatment option. This article intends to review the role of EVAR in the management of elective AAA. To assess the effectiveness of EVAR versus conventional OSR in individuals with AAA considered fit for surgery, and EVAR versus best medical care in those considered unfit for surgery. This was determined by the effect on short, intermediate and long-term mortality, endograft related complications, re-intervention rates and major complications. The Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator (TSC) searched the Specialised Register (January 2013) and the Cochrane Central Register of Controlled Trials (CENTRAL) (2012, Issue 12). The TSC also searched trial databases for details of ongoing or unpublished studies. Prospective randomised controlled trials (RCTs) comparing EVAR with OSR in individuals with AAA considered fit for surgery. and comparing EVAR with best medical care in individuals considered unfit for surgery. We excluded studies with inadequate data or using an inadequate randomisation technique. Three reviewers independently evaluated trials for appropriateness for inclusion and extracted data using pro forma designed by the Cochrane PVD Group. We assessed the quality of trials using The Cochrane Collaboration's 'Risk of bias' tool. We entered collected data in to Review Manager (version 5.2.3) for analysis. Where direct comparisons could be made, we determined odds ratios (OR). We tested studies for heterogeneity and, when present, we used a random-effects model; otherwise we used a fixed-effect model. We tabulated

    When tics caused by Tourette Syndrome cause meaningful impairment for patients, a comprehensive treatment approach includes education of patients, peers, and family, treatment of comorbid behavioral disorders if present, and consideration of behavior therapy and pharmacotherapy for tics themselves. This systematic review and meta-analysis demonstrates that behavior therapies based on Habit Reversal Therapy, including the Comprehensive Behavioral Intervention for Tics are effective in reducing tic severity when compared with supportive psychotherapy. When these behavior
