  1. The programmed nursing care for lower extremity deep venous thrombus patients receiving interventional thrombolysis: its effect on living quality

    International Nuclear Information System (INIS)

    Objective: Tu study the effect of comprehensive programmed nursing intervention on the living quality in patients with lower extremity deep venous thrombus who receive interventional thrombolysis therapy. Methods: A total of 60 patients receiving interventional thrombolysis due to lower extremity deep venous thrombus were randomly and equally divided into two groups. Patients in study group (n=30) was treated with comprehensive programmed nursing intervention in addition to the conventional therapy and routine nursing care, while patients in control group (n=30) was treated with the conventional therapy and routine nursing care only. The conventional therapy and routine nursing care included the nursing assessment before the operation, observation of the vital signs and the cooperation psychological care during the operation, the performance of medication according to the doctor's orders after the operation, etc. The comprehensive programmed nursing intervention included the nursing assessment of the patient before operation and the scientifically making of the nursing plan, which mainly referred to the cognitive behavior, the psychological care and the health education. They were systematically carried out during the perioperative period. One month after discharge the patients were asked to pay a return visit. The living quality was evaluated with relevant standards, and the results were compared between the two groups. Results: The score of living quality in the study group was significantly higher than that in the control group (P<0.01). Conclusion: The comprehensive programmed nursing intervention can significantly improve the living quality of lower extremity deep venous thrombosis patients who receive interventional thrombolysis therapy.

    Patients receiving intravenous thrombolysis with recombinant tissue plasminogen activator (IVT) for ischemic stroke are monitored in an intensive care unit (ICU) or a comparable unit capable of ICU interventions due to the high frequency of standardized neurological exams and vital sign checks. The present study evaluates quantitative infarct volume on early post-IVT MRI as a predictor of critical care needs and aims to identify patients who may not require resource intense monitoring. We identified 46 patients who underwent MRI within 6 h of IVT. Infarct volume was measured using semiautomated software. Logistic regression and receiver operating characteristics (ROC) analysis were used to determine factors associated with ICU needs. Infarct volume was an independent predictor of ICU need after adjusting for age, sex, race, systolic blood pressure, NIH Stroke Scale (NIHSS), and coronary artery disease (odds ratio 1.031 per cm{sup 3} increase in volume, 95 % confidence interval [CI] 1.004-1.058, p = 0.024). The ROC curve with infarct volume alone achieved an area under the curve (AUC) of 0.766 (95 % CI 0.605-0.927), while the AUC was 0.906 (95 % CI 0.814-0.998) after adjusting for race, systolic blood pressure, and NIHSS. Maximum Youden index calculations identified an optimal infarct volume cut point of 6.8 cm{sup 3} (sensitivity 75.0 %, specificity 76.7 %). Infarct volume greater than 3 cm{sup 3} predicted need for critical care interventions with 81.3 % sensitivity and 66.7 % specificity. Infarct volume may predict needs for ICU monitoring and interventions in stroke patients treated with IVT. (orig.)

    Coronary heart disease (CHD) is a major cause of mortality in India. Patients in India, who have acute coronary syndromes, have a higher rate of STEMI than do patients in developed countries. Since most of these patients are poor, they are less likely to get evidence-based treatments, and have a greater 30-day mortality. Reduction of delays in access to hospital and provision of affordable treatments could reduce this. Treatment regimes for AMI should aim to open the artery as soon as possible and as wide as possible. In patients suitable for thrombolytic treatment, time is critical and reperfusion should be initiated as soon as possible. Some adjunctive therapies are also beneficial, in particular, the antiplatelet agent aspirin, which should be given in the prehospital setting when a diagnosis of AMI is suspected. Despite availability of good treatment, mortality from AMI is showing no further reduction due to the prehospital phase and in-hospital delays. Thrombolysis is almost always delivered to patients after arriving in hospital, losing valuable time (and hence heart muscle). Newer drugs combined with recognition of improved outcomes have prompted attempts to decrease the time from symptom onset to treatment delivery via Pre Hospital Thrombolysis (PHT). However, PHT is significantly superior to in-hospital thrombolysis (IHT). This is especially important in regions where PCI is not available. In the RIKS-HIA and NRMI, PHT had better outcomes than IHT, but patients who received PPCI had lower mortality and re-infarction rates. They concluded that within 2 h of symptom onset, patients should receive PHT only if PPCI is not available within 4 h. In CAPTIM, which compared PPCI and PHT followed by PCI if thrombolysis failed and in GRACIA-1 trial, which tested the role of systematic PCI within 24 h of thrombolysis, the policy of systematic PCI following thrombolysis yielded better results than conservative management.

    The science of metric-based patient stratification for intravenous thrombolysis, revolutionized by the landmark National Institute of Neurological Disorders and Stroke trial, has transformed acute ischaemic stroke therapy. Recanalization of an occluded artery produces tissue reperfusion that unequivocally improves outcome and function in patients with acute ischaemic stroke. Recanalization can be achieved mainly through intravenous thrombolysis, but other methods such as intra-arterial thrombolysis or mechanical thrombectomy can also be employed. Strict guidelines preclude many patients from being treated by intravenous thrombolysis due to the associated risks. The quiet art of informed patient selection by careful assessment of patient baseline factors and brain imaging could increase the number of eligible patients receiving intravenous thrombolysis. Outside of the existing eligibility criteria, patients may fall into therapeutic 'grey areas' and should be evaluated on a case by case basis. Important factors to consider include time of onset, age, and baseline blood glucose, blood pressure, stroke severity (as measured by National Institutes of Health Stroke Scale) and computer tomography changes (as measured by Alberta Stroke Programme Early Computed Tomography Score). Patients with traditional contraindications such as wake-up stroke, malignancy or dementia may have the potential to receive benefit from intravenous thrombolysis if they have favourable predictors of outcome from both clinical and imaging criteria. A proportion of patients experience complications or do not respond to intravenous thrombolysis. In these patients, other endovascular therapies or a combination of both may be used to provide benefit. Although an evidence-based approach to intravenous thrombolysis for acute ischaemic stroke is pivotal, it is imperative to examine those who might benefit outside of protocol-driven practice.

    The authors have shown that bubble expansion and collapse near the interface between two materials with modest property differences produces jet-like interpenetration of the two materials. The bubble dynamics at a water-viscous fluid interface is compared with that at the interface of water with a weak elastic-plastic material. The authors find that, despite rather similar behavior during bubble growth and the initial portion of bubble collapse, the terminal jetting behavior is quite different, even in direction. The elastic-plastic properties chosen realistically represent real and surrogate thrombus. Simulations using the elastic-plastic model quantitatively agree with laboratory thrombolysis mass removal experiments. In the earlier simulations of laboratory experiments, walls have been remote so as to not effect the dynamics. Here the authors present two-dimensional simulations of thrombolysis with water over elastic-plastic surrogate thrombus in a geometry representative of the clinical situation. The calculations include thin cylindrical elastic walls with properties and dimensions appropriate for arteries. The presence of these artery walls does not substantially change the interface jetting predicted in unconfined simulations.

  12. Thrombolysis in acute ischemic stroke: a simulation study to improve pre- and in-hospital delays in community hospitals.

    Maarten M H Lahr

    Full Text Available BACKGROUND: Various studies demonstrate better patient outcome and higher thrombolysis rates achieved by centralized stroke care compared to decentralized care, i.e. community hospitals. It remains largely unclear how to improve thrombolysis rate in decentralized care. The aim of this simulation study was to assess the impact of previously identified success factors in a central model on thrombolysis rates and patient outcome when implemented for a decentral model. METHODS: Based on a prospectively collected dataset of 1084 ischemic stroke patients, simulation was used to replicate current practice and estimate the effect of re-organizing decentralized stroke care to resemble a centralized model. Factors simulated included symptom onset call to help, emergency medical services transportation, and in-hospital diagnostic workup delays. Primary outcome was proportion of patients treated with thrombolysis; secondary endpoints were good functional outcome at 90 days, Onset-Treatment-Time (OTT, and OTT intervals, respectively. RESULTS: Combining all factors might increase thrombolysis rate by 7.9%, of which 6.6% ascribed to pre-hospital and 1.3% to in-hospital factors. Good functional outcome increased by 11.4%, 8.7% ascribed to pre-hospital and 2.7% to in-hospital factors. The OTT decreased 17 minutes, 7 minutes ascribed to pre-hospital and 10 minutes to in-hospital factors. An increase was observed in the proportion thrombolyzed within 1.5 hours; increasing by 14.1%, of which 5.6% ascribed to pre-hospital and 8.5% to in-hospital factors. CONCLUSIONS: Simulation technique may target opportunities for improving thrombolysis rates in acute stroke. Pre-hospital factors proved to be the most promising for improving thrombolysis rates in an implementation study.

    Time to thrombolysis is a critical determinant of favourable outcomes in acute ischaemic stroke. It is not infrequent that patient outcomes are compromised due to out-of-hospital and in-hospital time delays. On the other hand, time delays could be minimised through the identification of barriers and the implementation of targeted solutions. This review outlines the different strategies in minimising treatment delays and offers recommendations. Literature search in PubMed, Medline and EBSCO Host was conducted to identify studies that are relevant to reduction of time to treatment from January 1995 to December 2012. Strategies to reduce time to thrombolysis are categorised into pre-hospital strategies, in-hospital strategies and post-treatment decision strategies. Proposed pre-hospital strategies include public education on stroke symptoms awareness, prioritising stroke by emergency medical services, increasing ease of access to medical records, pre-hospital notification, and mobile computed tomography scanning. In-hospital strategies include a streamlined code stroke system, computed tomography scanner co-location with emergency department, 24/7 availability of stroke physicians, point-of-care laboratory testing and access to expert neuroimaging interpretation. Post-decision strategies include increasing availability of intravenous thrombolysis and simplification of informed consent procurement. Time to thrombolysis delays is multifactorial. Effective reduction of time delays for acute ischaemic stroke requires the correct identification of and targeted strategies to overcome time barriers. PMID:23734983

To identify the factors of the increasing the availability and effectiveness of pre-hospital thrombolytic therapy of patients with ST segment elevation acute coronary syndrome (STEACS. Material and methods. STEACS patients (n=70 were included in the study and stratified into two groups. Patients of the 1st group (n=30 received emergency medical assistance from the feldsher teams and patients of the 2nd group (n=40 — from the doctor teams. Expert estimation approach was used for the real practice assessment. Results. The hospital-matched diagnose rate was 97.5% in the doctor teams in comparison with 76.7% in feldsher teams (p<0.05. The efficiency of pre-hospital thrombolysis in 90 minutes after its beginning was 60.1% for the doctor teams versus 73.3% for the feldsher teams (p>0.05. The deviation from the standard operating procedure of the medical care for myocardial infarction patients was observed more often in the doctor teams in comparison with this in the feldsher teams. Time for the decision about pre-hospital thrombolysis start, the rate of unreasonable use or unreasonable refusal of thrombolysis did not differ significantly in feldsher and doctor teams. Conclusion. To increase the effectiveness of pre-hospital thrombolysis therapy it is necessary to follow strictly the standard of the medical care for patients with acute coronary syndrome. One of the main approaches to improve the availability of up to date medical care technologies in STEACS treatment is implementation of pre-hospital thrombolysis in practice of feldsher teams.

    Full Text Available Background: Acute management of ischemic stroke involves thrombolysis within 4.5 h. For a successful outcome, early recognition of stroke, transportation to the hospital emergency department immediately after stroke, timely imaging, proper diagnosis, and thrombolysis within 4.5 h is of paramount importance. Aim: To analyze the obstacles for thrombolysis in acute stroke patients. Materials and Methods: The study was conducted in a tertiary care center in South India. A total of hundred consecutive patients of acute ischemic stroke who were not thrombolysed, but otherwise fulfilled the criteria for thrombolysis were evaluated prospectively for various factors that prevented thrombolysis. The constraints to thrombolysis were categorized into: i Failure of patient to recognize stroke symptoms, ii patient′s awareness of thrombolysis as a treatment modality for stroke, iii failure of patient′s relative to recognize stroke, iv failure of primary care physician to recognize stroke, v transport delays, vi lack of neuroimaging and thrombolysis facility, and vii nonaffordability. Results: The biggest hurdle for early hospital presentation is failure of patients to recognize stroke (73%, followed by lack of neuroimaging facility (58%, nonaffordability (56%, failure of patient′s relative to recognize stroke (38%, failure of the primary care physician to recognize stroke (21%, and transport problems (13%. Awareness of thrombolysis as a treatment modality for stroke was seen only in 2%. Conclusion: Considering the urgency of therapeutic measures in acute stroke, there is necessity and room for improvement to overcome various hurdles that prevent thrombolysis.

    International Nuclear Information System (INIS)

    Introduction: Percutaneous mechanical thrombectomy (PMT) is a third choice of treatment for acute arterial occlusions, in addition to thrombolysis and surgical thrombectomy. The aim of this retrospective study was to compare the combined treatment of PMT and local thrombolysis with thrombolysis therapy alone. Materials and methods: Sixty-nine patients with acute (<14 days [n = 35]) or subacute (14–42 days [n = 34]) femoropopliteal bypass occlusions were treated with PMT combined with thrombolysis. Seventy-two patients with acute [n = 40] or subacute [n = 32] femoropopliteal bypass occlusions were treated with thrombolysis alone. The thrombolysis in myocardial infarction (TIMI) classification was used to assess the bypass occlusion. Local thrombolysis time and dosage, reopening time, time in the intensive care unit, necessary surgical re-interventions, and clinical outcome were compared between the 2 groups. Results: The TIMI scores were significantly higher in the PMT plus thrombolysis group than in the thrombolysis group (acute occlusions 1188 versus 935, p < 0.001; subacute occlusions 935 versus 605, p < 0.001). The total urokinase dosage, the total hours of thrombolysis, time in the intensive care unit, and total hospital stay in the acute PMT plus thrombolysis group were significantly lesser than those in the thrombolysis group. After 24 h of treatment, the ankle-brachial index improved in all groups (p < 0.001): in the acute and subacute PMT plus thrombolysis group to 0.63 ± 0.14 and 0.43 ± 0.08, respectively; and in the acute and subacute thrombolysis group to 0.51 ± 0.11 and 0.41 ± 0.04, respectively. Conclusions: PMT combined with thrombolysis is a safe and very effective therapy for acute and subacute femoropopliteal bypass occlusions compared to treatment with thrombolysis alone

    Bubble dynamics plays a key role in many medical procedures including Laser Thrombolysis (L-T), acoustic and laser lithotripsy, interocular laser surgery, photoacoustic drug delivery, and perhaps ultrasonic imaging. The authors are investigating the effect that interfaces of different materials, especially biological and biomedical materials, have on the dynamics of nearby bubbles. Collapsing bubbles often become nonspherical, resulting in spectacular directed motion with potentially both beneficial and undesirable consequences. This directed motion may explain L-T mass removal and some types of laser-induced tissue damage.

    The objective of this study was to evaluate the efficacy and safety of intra-arterial thrombolysis in treating acute cerebral infarction and further discuss the indications of acute cerebral infarction treatment, in order to enhance the therapeutic effects of arterial thrombolysis. The data of 164 patients with acute cerebral infarction who accepted intra-arterial thrombolysis treatment by using rt-PA or reteplase between 2009 and 2014 at the Department of Neurology of our hospital, were collected, including patients' medical history, characteristics of the onset procedure, intervals between onset and intra-arterial thrombolysis, bleeding or death, and the changing process of patient's main neurologic function after the treatment. The neurological functions including muscle strength, speech, and level of consciousness were chosen for evaluation. Through a review of cerebral angiography, we collected the digital subtraction angiography (DSA) morphological changes of blood vessels before and after arterial thrombolysis to evaluate whether those blood vessels had been reperfused. Thereafter, we analyzed and statistically processed above-mentioned data. The mean time of arterial thrombolysis was 5.7 h. DSA results were as follows: 22 patients had complete internal carotid artery (ICA) occlusion; 49 patients middle cerebral artery's (MCA's) Ml or M2 segment occlusion; 6 patients anterior cerebral artery (ACA) occlusion; 58 patients reperfusion after thrombolysis, and the recanalization rate was 76 %. Based on vertebral-basilar artery (VBA) system, 18 patients had complete occlusion, 11 patients had reperfusion after thrombolysis, and the recanalization rate was 61 %. A total of 63 patients had severe stenosis, and they had significantly improved after thrombolysis. The clinical symptoms of patients were improved: 79 out of 164 patients with paralysis had partially recovered their limb muscle strength after operation, while 33 patients had completely recovered, and

    Full Text Available Intravenous thrombolysis (IVT is an accepted therapy in patients with acute ischemic stroke presenting within 3-4.5 hours of symptom onset. Selection of the patient for thrombolysis depends on the careful assessment for the risk of post thrombolysis symptomatic haemorrhage (6.2-8.9% which may be fatal. Atrial myxomas which are the commonest tumors of the heart are associated with stroke due to tumor/clot embolism. There are very few case reports of IVT and its outcome in patients with atrial myxoma with stroke. Some have reported successful thrombolysis, while others have reported intracerebral bleeding. In this report we describe our experience of IVT in atrial myxoma patient with ischemic stroke and review the relevant literature.

  5. Intra-arterial thrombolysis for acute ischemic stroke

    International Nuclear Information System (INIS)

    Intra-arterial thrombolysis is a maturing treatment for acute thromboembolic stroke that shows promise in restoring cerebral blood supply. Reviewed evidence suggests that intra-arterial treatment has a longer window for treatment than intravenous t-PA and does improve outcome. A favorable outcome is dependent on careful patient selection aimed at avoiding intracranial hemorrhage. This article describes features to evaluate for patient selection and highlights factors along the treatment algorithm to maximize success. (orig.)

    We performed a meta-analysis for systematic evaluation of the status quo of catheter thrombolysis for the treatment of acute lower limb deep vein thrombosis in China. We searched the China Biomedical bibliographic database (CBM), China National Knowledge Infrastructure (CNKI), Weipu full-text electronic journals, Wanfang full-text database, and Medline (1990 through June 2011) for clinical randomized controlled trials of catheter-directed thrombolysis and superficial venous thrombolysis to compare their efficacies for the treatment of acute deep vein thrombosis. The results were analyzed by using the Cochrane-recommended RevMan 4.2 software package, and the odds ratio (OR) was used as the combined measure of efficacy. The search retrieved 8 randomized controlled trials, and meta-analysis using the total rate of effective treatment as the clinical observation index found that the combined OR for the catheter thrombolysis group versus the superficial venous thrombolysis group was significant (P < 0.01; OR = 11.78; 95% confidence interval = 6.99-19.87). In conclusion, the meta-analysis indicated that catheter thrombolysis was more effective than superficial venous thrombolysis for the treatment of acute deep vein thrombosis in the lower limb in Chinese individuals. However, the included trials were only of medium quality, so more rational and scientific clinical trials are needed to validate this conclusion. PMID:25078578

    The presentation of acute pulmonary thromboembolism (PE) can be highly variable resulting in diagnostic challenges and management difficulties. Current guidelines suggest that therapy must be adjusted based on the severity of PE presentation. Systemic thrombolysis is the standard therapy for acute massive PE; however, systemic thrombolysis carries an estimated 20% risk of major hemorrhage, including a 3% to 5% risk of hemorrhagic stroke. There are data supporting the use of catheter-directed therapy (CDT) in massive and submassive PE, but past studies have limited its use to patients in whom systemic thrombolysis has either failed or was contraindicated. There is a paucity of data comparing the efficacy of CDT compared to systemic thrombolysis in different risk groups. This review will summarize the available data on the techniques and indications and outcomes of CDT for acute PE. PMID:26833207

    Many aspects of the physical process involved in a pulsed laser interacting with an occlusion in the intra-cranial vascular system are included in the simulation codes LATIS and LATIS3d. Laser light propagation and thermomechanical effects on the occlusion can be calculated by these codes. The hydrodynamic response uses a realistic equation of state which included melting and evaporation. Simple material strength and failure models now included in these codes are required to describe clot breakup. The goal is to ascertain the feasibility of laser thrombolysis, and to help optimize the laser parameters for such therapy. In this paper detailed numerical results for laser interaction with water is considered as an initial model for laser thrombolysis of soft blood clots which have high water content.

  9. S WAVE IN PULMONARY EMBOLISM, A NEW ECG SIGN TO AID THROMBOLYSIS

    Full Text Available Acute pulmonary embolism is a devastating disease that often leads to mortality . Previous investigators have found that thrombolysis reduces mortality in men but not significantly in women with pulmonary embolism. Many of the previous studies are with tenecteplase and alteplase. Here, we describe intra - venous thrombolysis with streptokinase in seven patients with pulmonary embolism who survived including two women. Further, we have one patient who had a new onset of S wave in lead I which subsequently disappeared after embolectomy. We also comment on the usefulness of shock sign in 2 deciding on thrombolysis .We propose a new sign for noninvasive assessment of need for thrombolysis in pulmonary embolism. New onset S wave in Lead I in pulmonary embolism can be used as a new sign for deciding the need for thrombolysis. When added to the shock sign it can be used in the emergency deparment to decide the need for thrombolysis. Further, there are no clear end points as to when to stop thrombolysis. In all 4 patients we switched to heparin when spontaneous bleeding or oozing started. In all 4 patients subsequent CT scans showed that the patient has mild to moderate resolution of the pulmonary embolism and patients remained stable and have been discharged and are under regular follow up. Hence we propose that bleeding can be used as an end point for thrombolysis in acute pulmonary embolism. We also describe a patient who had new onset S wave that disappeared after successful pulmonary embolectomy. Probably, the S wave is a marker of main pulmonary artery branch occlusions.

  10. Thrombolysis for acute myocardial infarction: drug review.

    Cundiff, David K

    2002-01-01

    The proof of efficacy of thrombolysis for acute myocardial infarction (AMI) depends on 9 randomized placebo-controlled trials totaling 58,511 patients. The meta-analysis of these trials showed an overall survival advantage of about 2% (11.5% vs 9.6%) in favor of thrombolysis. Iatrogenic deaths from thrombolysis complications occur in about 1% of AMI patients. Timely opening of the infarct-related artery (IRA) allowing myocardial reperfusion has been proposed to explain any survival advantage seen with thrombolysis ("open-artery hypothesis"). Angiographic data does not support the open-artery hypothesis as the mechanism of any benefit of thrombolysis. The "early hazard" (ie, increased mortality in the first 12 hours after thrombolysis) also suggests that the supposed survival benefit is due to something other than early reperfusion. The variable use of aspirin in the meta-analysis trials may have confounded the results and conclusions. In the 4 studies of the meta-analysis in which aspirin was used routinely (n = 21,144), the survival benefit was not statistically significant (P =.14). Lack of blinding in some studies and other methodologic problems may also call the conclusions of the meta-analysis into question. AMI registry reports comparing patients with and without thrombolysis have not borne out a significant survival advantage with thrombolysis. The National Registry of Myocardial Infarction (NRMI) registry data suggest that a significant number of AMI patients may be inappropriately receiving thrombolytics. An independent analysis of the NRMI mortality data adjusted for age and other risk factors would help determine whether thrombolysis for AMI improves survival. PMID:11965203

    Physician decision making is partially responsible for the roughly 30% of U.S. healthcare expenditures that are wasted annually on low-value care. In response to both the widespread public demand for higher-quality care and the cost crisis, payers are transitioning toward value-based payment models whereby physicians are rewarded for high-value, cost-conscious care. Furthermore, to target physicians in training to practice with cost awareness, the Accreditation Council for Graduate Medical Education has created both individual objective milestones and institutional requirements to incorporate quality improvement and cost awareness into fellowship training. Subsequently, some professional medical societies have initiated high-value care educational campaigns, but the overwhelming majority target either medical students or residents in training. Currently, there are few resources available to help guide subspecialty fellowship programs to successfully design durable high-value care curricula. The resource-intensive nature of pulmonary and critical care medicine offers unique opportunities for the specialty to lead in modeling and teaching high-value care. To ensure that fellows graduate with the capability to practice high-value care, we recommend that fellowship programs focus on four major educational domains. These include fostering a value-based culture, providing a robust didactic experience, engaging trainees in process improvement projects, and encouraging scholarship. In doing so, pulmonary and critical care educators can strive to train future physicians who are prepared to provide care that is both high quality and informed by cost awareness. PMID:25714122

  12. The interventional intra-arterial thrombolysis of acute ischemia of lower limb in elderly patients

    International Nuclear Information System (INIS)

    Objective: To investigate the efficacy and safety of intra-arterial thrombolysis by using interventional procedure for the treatment of acute ischemia of lower limb in elderly patients. Methods: During the period of Sep. 2007-March 2009 intra-arterial thrombolysis through interventional manipulation was performed in 18 elderly patients (aged 60 -87 years) with acute ischemia of lower limb. The clinical data, diagnoses, therapeutic schemes,perioperative complications and their managements, etc. were retrospectively analyzed. The efficacy and safety of intra-arterial thrombolysis for the treatment of acute ischemia of lower limb in elderly patients were evaluated. Results: The interval between the onset of symptom to confirmation of the diagnosis ranged from 4 hours to 12 days. Most patients were accompanied with several kinds of multi-system chronic diseases. Intra-arterial thrombolysis lasting for 1 -3 days was carried out, which was followed by endovascular angioplasty and stent implantation for the residual vascular lesions. The main complications that occurred in 15 patients included bleeding, postoperative fever, limb reperfusion injury, pulmonary embolism, etc. After the treatment,three patients had to receive toe amputation surgery (1 -3 toes), and successful limb salvage was obtained in 14 patients. One patient died of multiple organ failure due to reperfusion injury after revascularization. Conclusion: Intra-arterial thrombolysis with the aid of interventional manipulation is a safe and effective treatment for acute ischemia of lower limb in elderly patients, and in such clinical setting this technique should be considered as the treatment of first choice.

  13. Sequestrated Thrombolysis: Comparative Evaluation In Vivo

    International Nuclear Information System (INIS)

    Purpose: Lysis of a thrombus is a function of the local concentration of thrombolytic enzymes. This study was designed to determine in a porcine model of acute deep vein thrombosis (DVT) whether perithrombic sequestration of small volumes of a concentrated enzyme solution can accelerate the process of thrombolysis.Methods: DVT was induced in both hind limbs using a previously described technique (n = 32). Thirty minutes later the animal was heparinized and unilateral thrombolysis was attempted using 8 mg recombinant tissue plasminogen activator (rt-PA); saline was administered in the opposite leg. For conventional high-volume infusion (CI) (n = 5) rt-PA (0.067 mg/ml) was infused at 1 ml/min. For sequestrated thrombolysis the external iliac vein was endoluminally occluded, and rt-PA (0.25 mg/ml) administered either for proximal injection (ST-P) (n = 5), as a bolus every 3 min through a microcatheter placed via the balloon catheter, or for transthrombic injection (ST-T) (n = 5), as a bolus every 3 min through a Katzen wire in the balloon catheter. At autopsy, the thrombus mass in the iliofemoral veins was measured, and the extent of residual thrombosis in the venous tributaries graded at four sites. From these data a thrombolysis score was calculated.Results: One pig died before thrombolysis could be performed. Only with ST-T was residual thrombus mass in the test limb normalized to control, residual thrombus index (RTI), consistently less than unity. The median RTI of this group was 0.50 (range 0.39-0.97) compared with 1.22 (0.64-1.38) for ST-P and 0.88 (0.37-1.13) for CI. Compared with contralateral controls, a lower grade of residual thrombosis in tributaries was observed in test limbs at more venous sites with ST-T (8/20; 95% confidence interval 5-13) and ST-P (9/20; confidence interval 5-13) than with CI (2/20; confidence interval 0-5) (p= 0.04). A trend toward lower thrombolysis scores was observed with ST-T (p = 0.08). Systemic fibrinogenolysis was not

  14. Evaluation of interventional angioplasty by using thrombolysis and balloon dilatation in treating pulmonary embolism

    International Nuclear Information System (INIS)

    Objective: To evaluate the interventional angioplasty by using thrombolysis and balloon dilatation in the treatment of pulmonary embolism. Methods: Eight patients with pulmonary embolism were treated with interventional management including fragmentation of the thrombus, thrombolysis with urokinase flush infusion, balloon dilatation and continuing low-dose infusion for 24 hours. Anticoagulation with heparin was given simultaneously. Results: The pulmonary artery was completely recanalized in three patients, and partially recanalized in five patients. The blood oxygen saturation reached 100% in 3 cases and was over 93% in 5 cases. Conclusion: Interventional angioplasty by means of thrombolysis or balloon dilatation is an effective therapy for pulmonary embolism in reopening the embolized pulmonary artery, bringing the pulmonary hemodynamics to normal condition and correcting the hypoxemia.

  18. Prediction of stroke thrombolysis outcome using CT brain machine learning

    Directory of Open Access Journals (Sweden)

    Paul Bentley

    2014-01-01

    Full Text Available A critical decision-step in the emergency treatment of ischemic stroke is whether or not to administer thrombolysis — a treatment that can result in good recovery, or deterioration due to symptomatic intracranial haemorrhage (SICH. Certain imaging features based upon early computerized tomography (CT, in combination with clinical variables, have been found to predict SICH, albeit with modest accuracy. In this proof-of-concept study, we determine whether machine learning of CT images can predict which patients receiving tPA will develop SICH as opposed to showing clinical improvement with no haemorrhage. Clinical records and CT brains of 116 acute ischemic stroke patients treated with intravenous thrombolysis were collected retrospectively (including 16 who developed SICH. The sample was split into training (n = 106 and test sets (n = 10, repeatedly for 1760 different combinations. CT brain images acted as inputs into a support vector machine (SVM, along with clinical severity. Performance of the SVM was compared with established prognostication tools (SEDAN and HAT scores; original, or after adaptation to our cohort. Predictive performance, assessed as area under receiver-operating-characteristic curve (AUC, of the SVM (0.744 compared favourably with that of prognostic scores (original and adapted versions: 0.626–0.720; p < 0.01. The SVM also identified 9 out of 16 SICHs, as opposed to 1–5 using prognostic scores, assuming a 10% SICH frequency (p < 0.001. In summary, machine learning methods applied to acute stroke CT images offer automation, and potentially improved performance, for prediction of SICH following thrombolysis. Larger-scale cohorts, and incorporation of advanced imaging, should be tested with such methods.

    In general, around 80% of all strokes are ischemic. Take caring of the patients who have suffered an ischemic stroke is both expensive and time consuming. It is known that thrombolysis in patients with ischemic stroke can reduce the disability and increase the survival rate, however some patients still have poor outcomes. Therefore, to be able to predict the outcome of ischemic stroke patients after intravenous thrombolysis would be useful while making clinical decisions. In this study, we collected retrospective data of 82 ischemic stroke patients who received intravenous thrombolysis from July 2005 to June 2012 in Tri-service General Hospital. Of these patients, 10 died within 3 months, and only 36 patients made a good recovery. We used STATISTICA 10 software to select the best artificial neural network. The parameters of model 1 were age, blood sugar, onset to treatment time, National Institute of Health Stroke Scale (NIHSS) score, dense cerebral artery sign, and old stroke to predict 3-month outcomes. The parameters of model 2 were age, onset to treatment time, NIHSS score, hypertension, heart disease, diabetes and old stroke to predict the 3-month prognosis. The sensitivity, specificity and accuracy for model 1 were 77.78%, 80.43% and 79.27%, respectively, and 94.44%, 95.65% and 95.12%, respectively, for model 2. Artificial neural networks are used to establish prediction models with good performance to predict thrombolysis outcomes. These models may be able to help physicians to discuss and explain the likely outcomes to patients and their families before thrombolysis treatment. PMID:25000029

    Data regarding intravenous thrombolysis in stroke patients receiving new oral anticoagulant drugs (nOAC) is sparse. In the near future, however, an increasing number of patients with atrial fibrillation will suffer recurrent stroke despite treatment with nOAC. This will cause a significant therapeutic dilemma as thrombolysis is contraindicated under such circumstances. We describe an 81-year-old patient presenting with acute ischemic stroke who was successfully treated with intravenous thrombolysis despite ongoing treatment with rivaroxaban. Our case report indicates that thrombolysis under nOAC may be safe under certain conditions and emphasizes the importance of establishing and performing specific anticoagulation tests for nOAC.

  5. Enhanced spontaneous thrombolysis: a new therapeutic challenge.

    Kovacs, I B; Gorog, D A; Yamamoto, J

    2006-06-01

    Spontaneous thrombolysis is an endogenous protective mechanism against lasting arterial thrombotic occlusion, which is implicated in the pathogenesis of myocardial infarction and acute coronary events. Novel therapies for coronary heart disease (CHD) targeting atherosclerosis and thrombosis, together with cardiovascular prevention programs targeting risk-factors and lifestyle provide evidence that CHD is preventable. Although reduced fibrinolytic activity is a recognized risk-factor for ischemic cardiovascular events, it has so far been neglected. Our knowledge of the fibrinolytic effect of drugs commonly used for CHD such as antiplatelet agents (aspirin, ticlopidine, clopidogrel), anti-diabetic biguanides (phenformin, metformin) or anti-hypertensive drugs is scanty and conflicting. This is mainly due to the lack of a global test of spontaneous thrombolysis, as opposed to fibrinolysis of plasma or whole blood, i.e. the assessment of various activators and inhibitors of the fibrinolytic system. A recently described technique allows the measurement of spontaneous thrombolysis, that is, lysis of an autologous platelet-rich thrombus in the absence of added plasminogen activators. Early results suggest that this test may have significant clinical potential both in identifying those at risk of fatal cardiac events and in finding new therapeutic avenues or lifestyles to improve spontaneous thrombolytic activity.

  6. Basic ablation phenomena during laser thrombolysis

    1997-05-01

    This paper presents studies of microsecond ablation phenomena that take place during laser thrombolysis. The main goals were to optimize laser parameters for efficient ablation, and to investigate the ablation mechanism. Gelatin containing an absorbing dye was used as the clot model. A parametric study was performed to identify the optimal wavelength, spot size, pulse energies, and repetition rate for maximum material removal. The minimum radiant exposures to achieve ablation at any wavelength were measured. The results suggest that most visible wavelengths were equally efficient at removing material at radiant exposures above threshold. Ablation was initiated at surface temperatures just above 100 degrees Celsius. A vapor bubble was formed during ablation. Less than 5% of the total pulse energy is coupled into the bubble energy. A large part of the delivered energy is unaccounted for and is likely released partly as acoustic transients from the vapor expansion and partly wasted as heat. The current laser and delivery systems may not be able to completely remove large clot burden that is sometimes encountered in heart attacks. However, laser thrombolysis may emerge as a favored treatment for strokes where the occlusion is generally smaller and rapid recanalization is of paramount importance. A final hypothesis is that laser thrombolysis should be done at radiant exposures close to threshold to minimize any damaging effects of the bubble dynamics on the vessel wall.

  7. Salvage intraosseous thrombolysis and extracorporeal membrane oxygenation for massive pulmonary embolism

    2015-01-01

    Full Text Available Intraosseous access is an alternative route of pharmacotherapy during cardiopulmonary resuscitation. Extracorporeal membrane oxygenation (ECMO provides cardiac and respiratory support when conventional therapies fail. This case reports the use of intraosseous thrombolysis and ECMO in a patient with acute massive pulmonary embolism (PE. A 34-year-old female presented to the emergency department with sudden onset severe shortness of breath. Due to difficulty establishing intravenous access, an intraosseous needle was inserted into the left tibia. Echocardiography identified severe right ventricular dilatation with global systolic impairment and failure, indicative of PE. Due to the patient′s hemodynamic compromise a recombinant tissue plasminogen activator (Alteplase bolus was administered through the intraosseous route. After transfer to the intensive care unit, venous-arterial ECMO was initiated as further therapy. The patient recovered and was discharged 36 days after admission. This is the first report of combination intraosseous thrombolysis and ECMO as salvage therapy for massive PE.

    Specific therapy of acute spinal ischemia is not established. We report the first case of an MRI-verified cervical spinal ischemia treated by thrombolysis and review the literature. A 72-year old woman with right-sided motor hemiparesis and trunk ataxia was treated by intravenous thrombolysis with full recovery. Three days later she developed again a severe right-sided sensorimotor hemiparesis and a second off-label intravenous thrombolysis was repeated. Magnetic resonance imaging revealed a right-sided posterior-lateral cervical spinal ischemia. Spinal ischemia may clinically present with a cerebral-stroke-like picture challenging diagnostic and therapeutic procedure. Systemic thrombolysis might be a treatment option in acute spinal ischemia. In addition, early repeated systemic thrombolysis may be considered in selected strokes. PMID:26762860

  9. Differential diagnosis of hyperdensities on computed tomography immediately after intra-arterial thrombolysis in patients with acute ischemic stroke

    International Nuclear Information System (INIS)

    Objective: The present study was to differentiate the hyperdensities on CT immediately after intra-arterial thrombolysis in patients with acute ischemic stroke. Methods: Twenty two patients with acute ischemic stroke were treated with intra-arterial combining with intravenous thrombolysis within 6 hours after onset. All patients underwent nonenhanced CT scans before, immediately and 24 hours after thrombolytic therapy. The hyperdensities on CT after intra-arterial thrombolysis were analyzed retrospectively. Results: Five hyperdense areas were seen in 22 patients immediately after thrombolytic therapy. According to their locations, CT values and follow-up CT scans, the hyperdensities on CT imaging were classified into two groups: contrast enhancement and hemorrhagic transformation. The former was characterized by rapid clearance of the hyperdensity lesion with maximum Hounsifild Unit 90. Two of the five hyperdense lesion patients were confirmed to be contrast enhancement with location in cerebral cortex, the other were hemorrhagic transformation, mostly located in basal ganglia. Hyperdensity in patients with contrast enhancement showed neurological improvement although no further medical cares were offered. Conclusions: Different kind of hyperdensity on CT immediately after intra-arterial thrombolysis in patients with acute ischemic stroke can be differentiated according to its location, CT value and follow-up CT scan. When contrast enhancement occurred, no further medical care is needed. (authors)

  10. Experimental thrombolysis of middle cerebral artery thromboemboli

    International Nuclear Information System (INIS)

    Since the majority of ischaemic cerebral infarcts is caused by thromboemboli, we determined the benefit of firbrinolytic therapy in acute stroke. Thromboemboli were induced in the middle cerebral artery of 21 dogs. Urokinase was started at different time intervals after infarction (1, 3 and 5 hours) at a rate of 1000 IU/kg/min. Angiographically controlled thrombolysis was achieved in all 15 treated cases, whereas in the control group (n=6) no case of recanalisation was observed. Systemic fibrinolysis occurred in all cases. Postmortem examinations of the brains showed no intracerebral haemorrhages. Our findings indicate the urokinase treatment may be of value in acute ischaemic stroke. (orig.)

    Stroke is a major cause of death and disability worldwide. The resulting burden on society grows with the increase in the incidence of stroke. The term brain attack was introduced to describe the acute presentation of stroke and emphasize the need for urgent action to remedy the situation. Though a large number of therapeutic agents, like thrombolytics, NMDA receptor antagonists, calcium channel blockers and antioxidants, have been used or are being evaluated, there is still a large gap between the benefits of these agents and the properties of an ideal drug for stroke. So far, only thrombolysis with rtPA within a 3-hour time window has been shown to improve the outcome of patients with ischemic stroke. Understanding the mechanisms of injury and neuroprotection in these diseases is important to target news sites for treating ischemia. Better evaluation of the drugs and increased similarity between the results of animal experimentation and in the clinical setting requires critical assessment of the selection of animal models and the parameters to be evaluated. Our laboratory has employed a rat embolic stroke model to investigate the combination of rtPA with citicoline as compared to monotherapy alone and investigated whether neuroprotection should be provided before or after thrombolysis in order to achieve a greater reduction of ischemic brain damage.

  15. Local thrombolysis for patients of severe cerebral venous sinus thrombosis during puerperium

    International Nuclear Information System (INIS)

    Objective: To explore and evaluate the efficacy of intrasinus thrombolysis (IST) in patients with cerebral venous sinus thrombosis (CVST) during postpartum period. Methods: 11 patients during postpartum period with CVST who received IST during July 2007–November 2011 were included. Urokinase was infused into the sinuses via a microcatheter. Magnetic resonance venography (MRV) was performed to assess the recanalization of venous sinuses. Results: Before discharge, the intracranial pressure in 11 patients was under 200 mmH2O. MRV confirmed that venous sinus of 9 patients were smooth. The cortex venous and deep venous recovered to normal. Venous sinus of 2 patients recanalized partly, and cortex venous and deep venous had compensation. 9 patients had good outcome and 2 patients had only mild deficits. Conclusion: Intrasinus thrombolysis is safe and effective in patients with severe cerebral venous sinus thrombosis during postpartum period

    Treatment options for portomesenteric venous thrombosis range from anticoagulation to surgery, depending on chronicity, severity of symptoms, extent of thrombosis, and the availability of local expertise. For acute and subacute cases, a variety of endovascular options have been described in limited published series and case reports, including thrombolysis and mechanical thrombectomy. We report what is to our knowledge the first case in which the Trellis pharmacomechanical thrombolysis device was used successfully to treat complete acute thrombosis of the entire superior mesenteric vein and the entire portal vein with extension into all segmental intrahepatic portal branches in a young adult after liver transplantation. This device, coupled with adjunctive techniques using balloon catheters, facilitated complete restoration of flow, resulting in graft salvage and long-term patency.

    This paper assesses the extent of the financial burden due to out-of-pocket payments for health care incurred by people living with HIV (PLHIV) and the effect of this burden on their financial capacity. Data were collected in a cross-sectional survey of 353 PLHIV from three cities in Indonesia (Jakarta, Jogjakarta and Merauke). Respondents in Jakarta were sampled from one hospital and one non-governmental organization working with PLHIV. In Jogjakarta and Merauke, all HIV patients on antiretroviral therapy (ART) who came to selected hospitals during the interview period were asked to participate in the survey. The survey collected data on the frequency and extent of payments for HIV-related care, with answers cross-checked against medical records. Results show that PLHIV had different burdens of payments in the different geographical areas. On average, respondents in Jogjakarta spent 68%, and PLHIV on ART in Jakarta spent 96%, of monthly expenditure for HIV-related care, indicating a substantial financial burden for many ART patients. These patients depended on several sources of finance to cover the costs of their care, with donations from their immediate family being the most common method, selling assets and payments from personal income being the second most common method in Jakarta and Jogjakarta, respectively. Most PLHIV in these two areas did not have insurance. In Merauke, there were little observed out-of-pocket payments because the government covers medical costs via the local budget and health insurance for the poor. The results of this study confirm previous findings that providing subsidized ART drugs alone does not ensure financial accessibility to HIV care. Thus, the government of Indonesia at central and local levels should consider covering HIV care additional to providing antiretroviral drugs free of charge. Social health insurance should also be encouraged. PMID:20156918

  1. Patient Experienced Continuity of Care in the Psychiatric Healthcare System—A Study Including Immigrants, Refugees and Ethnic Danes

    2014-09-01

    Full Text Available Aim: The purpose of this study was to investigate continuity of care in the psychiatric healthcare system from the perspective of patients, including vulnerable groups such as immigrants and refugees. Method: The study is based on 19 narrative interviews conducted with 15 patients with diverse migration backgrounds (immigrants, descendents, refugees, and ethnic Danes. Patients were recruited from a community psychiatric centre situated in an area with a high proportion of immigrants and refugees. Data were analysed through the lens of a theoretical framework of continuity of care in psychiatry, developed in 2004 by Joyce et al., which encompasses four domains: accessibility, individualised care, relationship base and service delivery. Results: Investigating continuity of care, we found issues of specific concern to immigrants and refugees, but also commonalities across the groups. For accessibility, areas pertinent to immigrants and refugees include lack of knowledge concerning mental illness and obligations towards children. In terms of individualised care, trauma, additional vulnerability, and taboo concerning mental illness were of specific concern. In the domain of service delivery, social services included assistance with immigration papers for immigrants and refugees. In the relationship base domain, no differences were identified. Implications for priority area: The treatment courses of patients in the psychiatric field are complex and diverse and the patient perspective of continuity of care provides important insight into the delivery of care. The study highlights the importance of person-centred care irrespective of migration background though it may be beneficial to have an awareness of areas that may be of more specific concern to immigrants and refugees. Conclusions: The study sheds light on concerns specific to immigrants and refugees in a framework of continuity of care, but also commonalities across the patient groups.

  2. Therapeutic evaluation of catheter-directed thrombolysis for the treatment of acute arterial ischemia of lower extremities

    International Nuclear Information System (INIS)

    Objective: To evaluate the therapeutic effect and safety of catheter-directed thrombolysis in treating acute arterial ischemia of lower extremities. Methods: From Jan. 1, 2008 to Dec. 31, 2009, a total of 56 patients with acute arterial ischemia of lower extremities, who were encountered at the affiliated Renji hospital of Shanghai Jiaotong University, received catheter-directed thrombolysis treatment with urokinase. The therapeutic effect,safety and complications were observed and analyzed. Results: Of the total 56 cases, complete cure was obtained in 10 (17.8%), effective response in 38 (67.9%) and valueless in 8 (14.3%) with an overall effectiveness of 85.7%. Complications occurred in 11 cases (19.6%). The complications happened in six cases (10.7%) were directly related to the catheter-directed thrombolysis, which included hematoma at puncture site (n = 5, 8.9%) and bleeding due to the rupture of cerebrovascular malformation (n = 1, 1.7%). Conclusion: Catheter-directed thrombolysis is a safe and effective treatment for the acute arterial ischemia of lower extremities. (authors)

    Recent studies, in vitro and in vivo, have shown that High Intensity Focused Ultrasound (HIFU) accelerates thrombolysis, the dissolution of blood clots, for ischemic stroke. Although the mechanisms are not fully understood, cavitation is thought to play an important role in sonothrombolysis. The damage to a blood clot's fibrin fiber network from cavitation in a HIFU field is studied using two independent approaches for an embedded bubble. One method is extended to the more important scenario of a bubble outside a blood clot that collapses asymmetrically creating a jet towards the clot. There is significantly more damage potential from a bubble undergoing cavitation collapse outside the clot compared to a rapidly expanding bubble embedded within the clot structure. Also, the effects of the physical properties of skull bone when a HIFU wave propagates through it are examined by use of computer simulation. The dynamics of a test bubble placed at the focus is used in understanding of the pressure field. All other things being equal, the analysis suggests that skull thickness can alter the wave at the focus, which in turn can change the nature of cavitation bubble dynamics and the amount of energy available for clot damage.

    Full Text Available Background: Elderly patients with major ischemic strokes may remain severely disabled or dead. However, efficacy and safety of thrombolysis in this have not been fully explored. Materials and Methods: Data from the case records of patients aged >80 years with acute ischemic stroke with admission National Institute of Health Stroke Scale (NIHSS score ≥10 admitted between April 2009 and May 2011 were retrieved. Outcomes in patients treated with thrombolysis and control subjects were compared. Primary outcome was 3-month modified Rankin Scale (mRS score 0-2. Secondary outcomes were 3-month mRS score 0-3, mRS score 5-6, mortality, and improvement NIHHS score at discharge. Safety outcome was hemorrhagic transformation. Results: Study subjects included 22 patients treated with thrombolysis and 23 controls not treated with thrombolysis. Age, stroke severity, and proportion of identified major vessel occlusions were the variables for comparison between the two groups. More patients in the thrombolyzed group had mRS 0-2 outcome than in non-thrombolyzed group (18.2% vs. 0%; P = 0.049. Proportion of patients with mRS 0-3 outcome was also higher in thrombolyzed group than in non-thrombolyzed group (22.7% vs. 0%; P = 0.022. Patients in the thrombolyzed group had higher mortality, non-significant when compared to patients in the non-thrombolyzed group (18.2% vs. 8.7%; P = 0.414. However, lesser number of patients in the thrombolyzed group had mRS 5-6 outcome (35% vs. 65%; P = 0.075. Median improvement in NIHSS score at discharge also showed a more favorable trend in thrombolyzed group (10 vs. 2; P = 0.082. Rates of symptomatic and asymptomatic hemorrhagic transformations in thrombolyzed group were 4.5% and 27.3% respectively. Conclusion: For elderly patients with major ischemic strokes, thrombolysis offers a greater chance of functional independence.

    The New Zealand National Stroke Network introduced a National Stroke Thrombolysis Register on the first of January 2015 to assist with quality assurance and continuous service improvement. In the first 6 months, there were 179 [75 women, mean (SD) age 69.9 (14) years] treated with stroke thrombolysis out of a total of 2,796 ischaemic stroke patients, giving a national thrombolysis rate of 6.4%. The median [Inter-quartile range (IQR)] onset-to-treatment time was 154 (125-190) minutes, and the median (IQR) door-to-needle time was 74.5 (55.7-105.0) minutes. The rate of symptomatic intracranial haemorrhage following thrombolysis was 4.4%. These results are similar to other international centres, and indicate an approximate doubling of the proportion of stroke patients treated with stroke thrombolysis since a 2009 national audit. However, there is need for on-going efforts to improve treatment rates and process efficiency, particularly door-toneedle times. PMID:27447135

    Full Text Available Abstract Background Depressive disorder is currently one of the most burdensome disorders worldwide. Evidence-based treatments for depressive disorder are already available, but these are used insufficiently, and with less positive results than possible. Earlier research in the USA has shown good results in the treatment of depressive disorder based on a collaborative care approach with Problem Solving Treatment and an antidepressant treatment algorithm, and research in the UK has also shown good results with Problem Solving Treatment. These treatment strategies may also work very well in the Netherlands too, even though health care systems differ between countries. Methods/design This study is a two-armed randomised clinical trial, with randomization on patient-level. The aim of the trial is to evaluate the treatment of depressive disorder in primary care in the Netherlands by means of an adapted collaborative care framework, including contracting and adherence-improving strategies, combined with Problem Solving Treatment and antidepressant medication according to a treatment algorithm. Forty general practices will be randomised to either the intervention group or the control group. Included will be patients who are diagnosed with moderate to severe depression, based on DSM-IV criteria, and stratified according to comorbid chronic physical illness. Patients in the intervention group will receive treatment based on the collaborative care approach, and patients in the control group will receive care as usual. Baseline measurements and follow up measures (3, 6, 9 and 12 months are assessed using questionnaires and an interview. The primary outcome measure is severity of depressive symptoms, according to the PHQ9. Secondary outcome measures are remission as measured with the PHQ9 and the IDS-SR, and cost-effectiveness measured with the TiC-P, the EQ-5D and the SF-36. Discussion In this study, an American model to enhance care for patients with a

    Objectives Eligibility criteria for thrombolysis in ischemic stroke have been clearly defined. However, not all eligible patients benefit from this treatment. This study aimed to assess the determinants for clinical outcome in consecutive, eligible patients with ischemic stroke treated with thrombolysis in a single-center study. Methods Consecutive patients with ischemic stroke were treated with tissue plasminogen activator (t-PA) following the established eligibility National Institute of Neurological Disorders and Stroke (NINDS) and European Stroke Initiative (EUSI) criteria. Risk factors including blood pressure and pre-treatment glycemia were properly managed. Death and disability at 3 months were the study outcomes. Disability was evaluated by the Rankin-scale. Favorable outcome was defined as 0–2 and adverse outcome as 3–6 including death. Results Seventy-eight patients were included in the study in a single stroke unit. The mean age was 70.9 ± 13.2 years (range 36–94). Follow-up at 3 months was completed in 73 patients. A favorable outcome was observed in 37 patients (50%) and adverse outcome in 36 (36%). Nine patients (12.3%) died within 3 months. The presence of an occluded carotid artery was a strong predictor for adverse outcome (p < 0.0001). A low NIH Stroke Scale-Score (NIHSS) at admission was a associated with a favorable outcome, while history of diabetes mellitus led to an unfavorable outcome. Conclusion Among patients eligible for thrombolysis, many do not benefit from this treatment. These include patients with carotid occlusion and diabetes. PMID:18078026

    Purpose: To assess the feasibility and efficacy of catheter-directed thrombolysis with recombinant tissue plasminogen activator (rt-PA) for acute limb embolism in patients with recent cerebral embolism due to atrial fibrillation. Materials and methods: Eight patients (six men, two women; mean age 63.5 years) with acute embolic occlusion of two left common iliac arteries, four femoral arteries (three left; one right), and two right popliteal arteries were treated. All patients had a history of recent cerebral embolism (mean 6 days, range 5-15 days) and all had a history of atrial fibrillation (duration 5-10 years). Catheter-directed thrombolysis started a few hours (mean 6.2 h; range 3-10 h) after the onset of arterial embolism. Two 5 mg boluses of rt-PA were injected into the proximal clot through a 5 F end-hole catheter and, subsequently, two additional boluses of 5 mg rt-PA were injected into the emboli. In patients with residual emboli, infusion with rt-PA (1 mg/h) was continued. Percutaneous transluminal angioplasty was performed in three patients, and a stent was deployed in one patient. Results: Technical success was achieved in all patients. Clinical success rate was 87.5% (7/8). The one clinical failure was secondary to chronic occlusion of outflow runoff vessels. The mean duration of continuous rt-PA infusion was 3.6 h, the mean total dose of rt-PA administered was 23.6 mg (range 20-28 mg). There was no significant change in stroke scale scores during thrombolysis and no intracerebral haemorrhage was found at computed tomography (CT) after thrombolysis. Minor complications included haematomata at puncture sites (6/8), bleeding around the vascular sheath (2/8), and haematuria (1/8). During the follow-up period of 3-6 months, one patient suffered from recurrent cerebral embolism and died.

    In recent nanotechnology development, iron-based magnetic nanoparticles (MNPs) have been used in several investigations on biomedical research for small animal experiments. Their important applications include targeted drug delivery for therapeutic purpose, contrast agent for magnetic resonance imaging, and hyperthermia treatment for tumors. These MNPs can be guided by an external magnetic field due to their physical characteristics of superparamagnetism. In a recent report, authors indicated that covalently bound recombinant tissue plasminogen activator (rtPA) to MNP (MNPrtPA) with preserved enzyme activity may be guided by a bar magnet and induce target thrombolysis in an embolic model in rats. Delivery of rtPA by binding the thrombolytic drug to MNPs will improve the possibility of the drug to be delivered under magnetic guidance and retained in a local targeted area in the circulation system. In this work, an ex vivo intravascular thrombolysis model was developed to study the impact of external magnetic field on the penetration of MNP-rtPA in the blood clot samples. The samples were then scanned by a micro CT system for quantification. Images of MNPs show strong contrast with their surrounding blood clot materials. The optimum drug loading was found when 0.5 mg/ml rtPA is conjugated with 10 mg SiO2-MNP where 98% drug was attached to the carrier with full retention of its thrombolytic activity. Effective thrombolysis with tPA bound to SiO2-MNP under magnetic guidance was demonstrated in our ex vivo model where substantial reduction in time for blood clot lysis was observed compared with control groups without magnetic field application.

    Full Text Available Abstract Background The use of thrombolytic therapy in the treatment of thrombosed infrainguinal native arteries and bypass grafts has increased over the years. Main limitation of this treatment modality, however, is the occurrence of bleeding complications. Low intensity ultrasound (US has been shown to accelerate enzymatic thrombolysis, thereby reducing therapy time. So far, no randomized trials have investigated the application of US-accelerated thrombolysis in the treatment of thrombosed infra-inguinal native arteries or bypass grafts. The DUET study (Dutch randomized trial comparing standard catheter-directed thrombolysis versus Ultrasound-accElerated Thrombolysis for thrombo-embolic infrainguinal disease is designed to assess whether US-accelerated thrombolysis will reduce therapy time significantly compared with standard catheter-directed thrombolysis. Methods/design Sixty adult patients with recently (between 1 and 7 weeks thrombosed infrainguinal native arteries or bypass grafts with acute limb ischemia class I or IIa, according to the Rutherford classification for acute ischemia, will be randomly allocated to either standard thrombolysis (group A or US-accelerated thrombolysis (group B. Patients will be recruited from 5 teaching hospitals in the Netherlands during a 2-year period. The primary endpoint is the duration of catheter-directed thrombolysis needed for uninterrupted flow in the thrombosed infrainguinal native artery or bypass graft, with outflow through at least 1 crural artery. Discussion The DUET study is a randomized controlled trial that will provide evidence of whether US-accelerated thrombolysis will significantly reduce therapy time in patients with recently thrombosed infrainguinal native arteries or bypass grafts, without an increase in complications.

    If the appropriate catheterization of the affected vein was not possible because of a narrowed or thrombus-filled venous lumen, successful treatment gets into trouble during catheter directed regional thrombolysis for treatment of deep vein thrombosis. In this situation, intra-arterial thrombolysis can be considered as an alternative treatment, but to the best of our knowledge, only two reports have been described. We present here cases of successful intra-arterial thrombolysis in patients with deep vein thrombosis.

  19. The application of multi-modal MRI in venous thrombolysis therapy for hyperacute cerebral arterial thrombosis

    International Nuclear Information System (INIS)

    Objective: To investigate the value of MRI in thrombolytic therapy of hyperacute cerebral arterial thrombosis. Methods: One hundred and sixteen patients with acute cerebral arterial thrombosis were recruited, plain CT and multi-modal MRI were performed in all patients. Thirty-three patients with hyperacute cerebral infarction were treated by recombinant tissue plasminogen activator(rt-PA) and followed-up periodically using MRI. Results: The 33 patients with thrombolysis selected by MRI demonstrated clinical improvement, 90 d modified Rankin scale scores (mRs) were less than 2 and life quality Barthal indexes(BI) were from 80 to 100. The complication included one asymptomatic parenchymal hematoma(PH 1) one weeks after thrombolytic therapy and 4 (12.2%) hemorrhagic infarction(HI) 6 to 24 hours after thrombolytic therapy. Conclusions: MRI has significant clinical value for the screening and follow-up of intravenous thrombolytic therapy of hyperacute ischemic stroke. MRI-based thrombolysis is a safe and effective method for hyperacute ischemic stroke. (authors)

  20. Pharmacomechanical Thrombolysis for the Treatment of Thrombosed Native Arteriovenous Fistula: A Single-Center Experience

    International Nuclear Information System (INIS)

    Native arteriovenous fistula is one of the important routes for hemodialysis patients because of increased long-term survival and preservation of quality of life. We reported on a single-center experience with using pharmacomechanical thrombolysis for the treatment of thrombosed native arteriovenous fistula. This was a retrospective study of 12 hemodialysis patients (8 males and 4 females) with 14 thrombosed distal forearm Brescia-Cimino radiocephalic fistulas who were referred for pharmacomechanical thrombolytic treatment in the intervention unit of the Radiology Department, from 1 January 2010 to 30 December 2011. Demographic data, technical success rates, clinical success rates and complications were evaluated. The patency was evaluated by Kaplan-Meier analysis. The technical and clinical success was found in 12 thrombosed fistulas. Only 3 procedures had minor complications including small amounts of adjacent soft tissue hematoma. There were no procedure-related major complications. The primary patency rates at 6 and 12 months were 67% and 50%. The secondary patency rates at 6 and 12 months were 75% and 67%. Pharmacomechanical thrombolysis is a minimally invasive, effective, durable, and safe procedure for the treatment of thrombosed native arteriovenous fistula. This procedure can be considered as an alternative treatment for thrombosed dialysis fistulas

    Laser thrombolysis is the controlled ablation of a thrombus (blood clot) blockage in a living arterial system. Theoretical modeling of the interaction of laser light with thrombi relies on the ability to perform in vitro experiments with well characterized surrogate materials. A synthetic thrombus formulation may offer more accurate results when compared to in vivo clinical experiments. The authors describe the development of new surrogate materials based on formulations incorporating chick egg, guar gum, modified food starch, and a laser light absorbing dye. The sound speed and physical consistency of the materials were very close to porcine (arterial) and human (venous) thrombi. Photographic and videotape recordings of pulsed dye laser ablation experiments under various experimental conditions were used to evaluate the new material as compared to in vitro tests with human (venous) thrombus. The characteristics of ablation and mass removal were similar to that of real thrombi, and therefore provide a more realistic model for in vitro laser thrombolysis when compared to gelatin.

  2. Superselective ophthalmic intraarterial thrombolysis for central retinal artery thrombosis

    International Nuclear Information System (INIS)

    Objective: To investigate the effect of superselective ophthalmic artery thrombolysis for treatment of central retinal artery (CRAT). Methods: 250000-500000 u urokinase was directly perfused via ophthalmic artery (OA) through the retained superselective catheter after angiography into 8 eyes of 8 patients with CRAT. Results: The visual acuity (VA) was significantly improved in 4 eyes. the VA of 3 eyes reached 0.1-0.3 after 6 months follow-up. the other 3 eyes achieved no significant improvement of VA. The VA of 1 eye decreased from finger count (FC) to light perception (LP). Conclusions: Early diagnosis and early superselective trans-micro catheter thrombolysis would be more effective than traditional treatment. (authors)

    Randomized controlled trials that compared primary percutaneous transluminal coronary angioplasty with thrombolysis have shown that primary angioplasty is more effective than intravenous thrombolysis in reducing mortality and morbidity in patients with acute myocardial infarction. Three large myocardial infarction registries - MITI, NRMI-2 and French registry - failed to show an advantage of primary angioplasty compared with thrombolysis. One of the latest trials mentioned in this paper restored the place of primary angioplasty as superior to thrombolysis in acute myocardial infarction. Data of patients treated with primary percutaneous transluminal coronary angioplasty in Clinic of Cardiology of Vilnius University are presented. PMID:15079110

    It has been shown that high-intensity focused ultrasound can be an efficient method to induce thrombolysis, but the choice of the pulsed-wave parameters is critical and the risk of thermal lesions in neighbouring tissues is still an important issue. The present work aims at using a bifrequency excitation combining two neighbouring frequencies to reduce the intensity needed to achieve thombolysis without any pharmacological agent. In vitro clots of human blood are inserted in small tubes filled with physiological saline, and placed at the focus of a piezoelectric transducer. The typical clot weight before sonication is 700 mg. Ultrasound excitation consists in monofrequency (resp. bifrequency) pulsed wave at 550 kHz (resp. 535 kHz and 565 kHz), with a pulse length of 27 ms and a duty cycle of 1:10, emitted during 5 min. Efficiency of the thrombolysis is obtained weighting each clot after filtration on a 25 μm filter before and after sonication. The efficiencies of mono- and bi-frequency excitations are compared for intensities ranging from Isppa = 200 W/cm2 (Ispta = 20 W/cm2) to Isppa = 1700 W/cm2 (Ispta = 70 W/cm2). For each set of experiments, a control group of 3 non sonicated clots is used. In the conditions of the experiment, an intensity of Isppa = 1500 W/cm2 (Ispta = 150 W/cm2) is needed to achieve 80% of thrombolysis when monofrequency emission is used. With a bifrequency excitation, this intensity is reduced by 45%: the same thrombolysis efficiency is achieved with intensities of Isppa = 800 W/cm2 (Ispta = 80 W/cm2).

    Full Text Available Cardiac myxoma is a rare but curable cause of ischemic stroke. Current guidelines do not address the use of intravenous thrombolysis for embolic stroke caused by cardiac myxoma. The risk of hemorrhage due to occult tumor emboli or microaneurysms is a major concern. We describe a 45-year-old man who had an embolic stroke in the left middle cerebral artery. The initial National Institutes of Health Stroke Scale (NIHSS score was 16. He received intravenous thrombolysis 2 h and 52 min after stroke onset. No intracranial hemorrhage developed. A cardiac mass was found in the left atrium and removed surgically 84 h after stroke. Pathological study showed a myxoma with extensive hemorrhage and thrombus over the surface. At the 3-month follow-up, the NIHSS score was 9 and the modified Rankin scale score was 3. Our experience with this patient supports the hypothesis that intravenous thrombolysis may be safely used in the treatment of embolic stroke due to cardiac myxoma.

  8. Preparatory catheter-directed thrombolysis together with assisted endovascular angioplasty for the treatment of chronic occlusive arterial disorders of lower extremities

    International Nuclear Information System (INIS)

    Objective: To evaluate the safety and efficacy of preparatory catheter-directed thrombolysis together with assisted endovascular angioplasty in treating chronic occlusive arterial disorders of lower extremities. Methods: From January 2008 to December 2009, preparatory catheter-directed thrombolysis together with assisted endovascular angioplasty was performed in 12 patients with chronic occlusive arterial disorders of lower extremities, including 8 males and 4 females with an average age of 56.3 years (within a range of 38-71 years). All 12 patients had a history of chronic ischemia of lower limb,the mean ill duration was 19.3 months (3-48 months). All patients complained of intermittent claudication with a mean distance of 125 m (50-200 m). Rest pain occurred in 5 patients (42%), toe necrosis was seen in 3 patients (25%) and critically ischemic limb in 4 patients (33%). Ankle-brachial index (ABI) was 0.00 0.65 with a mean of 0.33. In all 12 patients catheter-directed thrombolysis with rt-PA or urokinase was initially carried out, which was followed by endovascular angioplasty (balloon dilatation or stent placement) in two days. The clinical data and the therapeutic results were analyzed. Results: Technical success was achieved in all 12 patients. The mean time of thrombolysis was 48 hours. Of 12 patients, rt-PA was employed in 4 and urokinase in 8. The occluded length of the diseased arteries before the treatment was 60-150 mm, with a mean of 80 mm. After catheter-directed thrombolysis,the occluded length decreased to 10-50 mm (mean of 30 mm). Endovascular angioplasty was successfully completed in all patients after thrombolysis therapy. Postoperative ABI was 0.64-1.0 (mean of 0.86), which was increased by 0.53 when compared to the preoperative figure. During the perioperative period neither complications needed to be surgically treated nor death occurred. All patients were followed up, and the arteries remained open after one year in all cases.

    The aim of the ICARO-3 study was to evaluate whether intra-arterial treatment, compared to intravenous thrombolysis, increases the rate of favourable functional outcome at 3 months in acute ischemic stroke and extracranial ICA occlusion. ICARO-3 was a non-randomized therapeutic trial that performed a non-blind assessment of outcomes using retrospective data collected prospectively from 37 centres in 7 countries. Patients treated with endovascular treatment within 6 h from stroke onset (cases) were matched with patients treated with intravenous thrombolysis within 4.5 h from symptom onset (controls). Patients receiving either intravenous or endovascular therapy were included among the cases. The efficacy outcome was disability at 90 days assessed by the modified Rankin Scale (mRS), dichotomized as favourable (score of 0-2) or unfavourable (score of 3-6). Safety outcomes were death and any intracranial bleeding. Included in the analysis were 324 cases and 324 controls: 105 cases (32.4 %) had a favourable outcome as compared with 89 controls (27.4 %) [adjusted odds ratio (OR) 1.25, 95 % confidence interval (CI) 0.88-1.79, p = 0.1]. In the adjusted analysis, treatment with intra-arterial procedures was significantly associated with a reduction of mortality (OR 0.61, 95 % CI 0.40-0.93, p = 0.022). The rates of patients with severe disability or death (mRS 5-6) were similar in cases and controls (30.5 versus 32.4 %, p = 0.67). For the ordinal analysis, adjusted for age, sex, NIHSS, presence of diabetes mellitus and atrial fibrillation, the common odds ratio was 1.15 (95 % IC 0.86-1.54), p = 0.33. There were more cases of intracranial bleeding (37.0 versus 17.3 %, p = 0.0001) in the intra-arterial procedure group than in the intravenous group. After the exclusion of the 135 cases treated with the combination of I.V. thrombolysis and I.A. procedures, 67/189 of those treated with I.A. procedures (35.3 %) had a favourable outcome, compared to 89/324 of

    Full Text Available Forced displacement related to persecution and violent conflict has reached a new peak in recent years. The primary aim of this study is to provide an initial overview of the acute and chronic health care problems of asylum seekers from the Middle East, with special emphasis on asylum seekers from Syria.Our retrospective data analysis comprised adult patients presenting to our emergency department between 01.11.2011 and 30.06.2014 with the official resident status of an "asylum seeker" or "refugee" from the Middle East.In total, 880 patients were included in the study. Of these, 625 (71.0% were male and 255 (29.0% female. The median age was 34 (range 16-84. 222 (25.2% of our patients were from Syria. The most common reason for presentation was surgical (381, 43.3%, followed by medical (321, 36.5% and psychiatric (137, 15.6%. In patients with surgical presentations, trauma-related problems were most common (n = 196, 50.6%. Within the group of patients with medical presentation, acute infectious diseases were most common (n = 141, 43.9%, followed by neurological problems (n = 70, 21.8% and gastrointestinal problems (n = 47, 14.6%. There were no differences between Syrian and non-Syrian refugees concerning surgical or medical admissions. The most common chronic disorder of unclear significance was chronic gastrointestinal problems (n = 132, 15%, followed by chronic musculoskeletal problems (n = 108, 12.3% and chronic headaches (n = 78, 8.9%. Patients from Syria were significantly younger and more often suffered from a post-traumatic stress disorder than patients of other nationalities (p<0.0001, and p = 0.05, respectively.Overall a remarkable number of our very young group of patients suffered from psychiatric disorders and unspecified somatic symptoms. Asylum seekers should be carefully evaluated when presenting to a medical facility and physicians should be aware of the high incidence of unspecified somatic symptoms in this patient population

Despite the multiple potential pathophysiological mechanisms for the relationship between thrombolysis and epileptic activity, seizures during this procedure are scarcely reported. Our hypothesis is that subtle and transient clinical seizures, like those described in our patient, may not be detected or are misdiagnosed as nonepileptic involuntary movements. We aimed to draw attention to the recognition challenge of this paroxysmal motor behavior, highlighting this clinical and neurophysiological identification using video recording and back-average analysis of the EEG.

    In India, stroke care services are not well developed. There is a need to explore alternative options to tackle the rising burden of stroke. Telemedicine has been used by the Indian Space Research Organization (ISRO) to meet the needs of remote hospitals in India. The telemedicine network implemented by ISRO in 2001 presently stretches to around 100 hospitals all over the country, with 78 remote/rural/district health centers connected to 22 specialty hospitals in major cities, thus providing treatment to more than 25 000 patients, which includes stroke patients. Telemedicine is currently used in India for diagnosing stroke patients, subtyping stroke as ischemic or hemorrhagic, and treating accordingly. However, a dedicated telestroke system for providing acute stroke care is needed. Keeping in mind India's flourishing technology sector and leading communication networks, the hub-and-spoke model could work out really well in the upcoming years. Until then, simpler alternatives like smartphones, online data transfer, and new mobile applications like WhatsApp could be used. Telestroke facilities could increase the pool of patients eligible for thrombolysis. But this primary aim of telestroke can be achieved in India only if thrombolysis and imaging techniques are made available at all levels of health care. PMID:25042038

A combination of anticoagulation, vasodilatation, and local selective and superselective thrombolysis with urokinase was performed to salvage the leg. As a result of the severe ischemia-induced pain, the patient had to be monitored over the complete therapy period on the intensive care unit with permanent administration of intravenous fluid and analgetics. We describe the presenting symptoms and the interventional technique, and we discuss the recent literature regarding the management of accidental intra-arterial injection of dissolved flunitrazepam tablets.

    This paper summarized the nursing experience of four cases of patients with inferior vena cava thrombosis, which were treated with temporary inferior vena cava filter (IVCF) combined with catheter-directed thrombolysis. The importance of nursing went to the placement of IVCF to prevent its displacement, limb nursing and catheter-directed thrombolysis. All the laboratory indexes were under the monitoring and measures were taken for the prevention of complication of pulmonary embolism and education for discharge was conducted as well. During the treatment, bleeding in puncture point occurred in one case, displacement of catheter one case and gastrointestinal bleeding one case and after treatment, all the swelling of extremities and inferior vena cava thrombosis disappeared. IVCF was removed 3 to 4 weeks after discharge and after 3 to 38 months follow-ups, no thrombosis reoccurred.%总结4例下腔静脉血栓患者行肾静脉以上临时腔静脉滤器植入联合腔内导管溶栓治疗的护理经验.做好临时性腔静脉滤器置入的护理,严防滤器移位;做好肢体护理及导管溶栓护理;密切观察患者出血情况,监测实验室指标;预防和观察肺栓塞并发症;做好出院指导.4例患者患肢肿胀消退,下腔静脉血栓均消失,出现穿刺点出血1例,导管移位1例,消化道出血1例,经及时发现积极治疗护理,痊愈出院,术后3~4 周拔除临时滤器,随防3~38 个月无血栓复发.

  1. Endovascular Thrombolysis Using Monteplase for Non-chronic Deep Venous Thrombosis

    International Nuclear Information System (INIS)

    This study was designed to evaluate the usefulness of endovascular thrombolysis using monteplase for deep venous thrombosis (DVT). Between December 2005 and October 2009, at our institution nine endovascular thrombolysis treatments with monteplase were performed for symptomatic DVT in eight patients (6 women, 2 men; mean age, 56 (range, 15-80) years). In all, systemic anticoagulation administered by the peripheral intravenous route with heparin and/or thrombolysis with urokinase followed by anticoagulation with orally administered warfarin had been performed, and subsequently six endovascular treatments without monteplase were administered. However, DVT persisted, and endovascular treatments with monteplase were tried. In six (67%) of the nine procedures, DVT completely or almost completely disappeared after endovascular thrombolysis with monteplase. Mean dose of monteplase used was 2,170,000 IU. There was only one procedure-related complication. In one patient, just after thrombolysis with monteplase, bleeding at the puncture site and gingival bleeding occurred. Bleeding was stopped by manual astriction only. Endovascular thrombolysis with monteplase may be an effective treatment for DVT, even in cases resistant to traditional systemic anticoagulation and thrombolysis and endovascular procedures without monteplase.

  2. Percutaneous mechanical thrombectomy combined with catheter-directed thrombolysis in the treatment of symptomatic lower extremity deep venous thrombosis

    International Nuclear Information System (INIS)

    Purpose: To evaluate the efficacy of percutaneous mechanical thrombectomy (PMT) combined with catheter-directed thrombolysis (CDT) in the treatment of massive symptomatic lower limb deep venous thrombosis (DVT). Materials and methods: One hundred and three clinically confirmed DVT patients were discharged from our institution. Sixteen patients with massive lower limb DVT were included in this retrospective study. After prophylactic placement of inferior vena cava filters (IVCFs), percutaneous mechanical thrombectomy (ATD, n = 10; Straub, n = 6) and catheter-directed thrombolysis were performed in all patients. Complementary therapy included percutaneous transluminal venous angioplasty (PTA, n = 3) and stent placement (n = 1). The doses of thrombolytic agents, length of hospital stay, peri-procedure complications and discharge status were reviewed. Oral anticoagulation was continued for at least 6 months during follow-up. Results: The average hospital stay was 7 days. The technical success rate (complete and partial lysis of clot) was 89%, the other 11% patients only achieved less than 50% clot lysis. The mean dose of urokinase was 3.3 million IU. There were no significant differences of clinical outcome between the ATD and Straub catheter group. The only major complication was an elderly male who experienced a fatal intracranial hemorrhage while still in the hospital (0.97%, 1/103). Minor complications consisted of three instances of subcutaneous bleeding. No transfusions were required. Vascular patency was achieved in 12 limbs during follow-up. No pulmonary emboli occurred. There is one recurrent DVT 4.5 months after the treatment. Conclusions: Percutaneous mechanical thrombectomy combined with catheter-directed thrombolysis is an effective and safe method for the treatment of symptomatic DVT. A randomized prospective study is warranted.

    Full Text Available Background. Patients with acute ischemic stroke due to internal carotid artery (ICA disease are at high risk of early stroke recurrence. A combination of IV thrombolysis and early carotid artery stenting (CAS may result in more effective secondary stroke prevention. Objective. We tested safety and durability of early CAS following IV thrombolysis in stroke patients with residual stenosis in the symptomatic ICA. Methods. Of consecutive patients treated with IV rtPA, those with residual ICA stenosis ≥70% or 24 hours. The protocol included pre-rtPA MRI and MR angiography, and post-rtPA carotid ultrasound and CT angiography. Stroke severity was assessed by the NIH Stroke Scale (NIHSS. Three- and twelve-month stent patency was assessed by ultrasound. Twelve-month functional outcome was assessed by the modified Rankin Scale (mRS. Results. Of 145 consecutive IV rtPA-treated patients, 6 (4% underwent early CAS. Median age was 76 (range 67–78 years, median NIHSS at stroke onset was 12 (range 9–16 and 7 (range 7-8 before CAS. Median onset-to-CAS time was 48 (range 30–94 hours. A single self-expandable stent was implanted to cover the entire lesion in all patients. The procedure was uneventful in all patients. After 12 months, all patients had stent patency, and the functional outcome was favourable (mRS ≤ 2 in all but 1 patient experiencing a recurrent stroke for new-onset atrial fibrillation. Conclusion. This small case series of a single centre suggests that early CAS may be considered a safe alternative to CEA after IV rtPA administration in selected patients at high risk of stroke recurrence.

    Thrombophilia, the state of increased tendency for blood clotting, is considered the disorder of a complex etiology, caused by both environmental and genetic factors. As gene variants predisposing to thrombophilia and influencing the increased risk of vein thrombosis might influence response to local thrombolysis, the aim of the work was to characterize the pharmacogenetic conditions for local streptokinase treatment in patients with a deep vein thrombosis (DVT) of lower extremities based on the following polymorphism analyses: G1691A polymorphism of factor V (FV), G20210A polymorphism of prothrombin (PT), A4250G (Thr312Ala) polymorphism of fibrinogen-alpha (FGA), G(-455)A polymorphism of fibrinogen-beta (FGB), 4G/5G polymorphism of plasminogen activator inhibitor type 1(PAI-1) and insertion/deletion (I/D) polymorphism of tissue plasminogen activator (t-PA). The study included 40 DVT patients who underwent a local thrombolytic treatment within 14-day period from diagnosis. Full recanalization was achieved in 20 subjects (50%) [group R(+)], whereas incomplete or total lack of recanalization was identified in the remaining 20 patients [group R(-)]. No major complications of thrombolytic treatment occurred in the studied group. In the case of prothrombin gene all individuals carried homozygous wild type genotype (GG). Prevalence of the genotypes and alleles of the remaining five polymorphisms did not differ significantly between the groups R(+) and R(-). Neither sex nor age, smoking or time period from diagnosis to introduction of the thrombolytic treatment significantly influenced treatment efficacy. The results of the study suggest that a local thrombolysis with streptokinase introduced within two week period from the diagnosis is a safe and efficient method of treatment for deep vein thrombosis of lower extremities. However, size of the group is insufficient to clearly determine the association between investigated polymorphisms and efficacy of local treatment with

    The UN Convention on the Rights of the Child (1989) asserts the right of every child to self-determination, dignity, respect, non-interference, and the right to make informed decisions. The provision of quality care in health services tailored to children's preferences means that health professionals have a responsibility to ensure children's rights, and that the child is encouraged and enabled to make his or her view known on issues that affect them. This paper will help illuminate and differentiate between a child perspective and the child's perspective in health care settings. The issues are supported with research which illustrates the different perspectives. Both perspectives are required to perceive and encounter children as equal human beings in child-centred health care settings. PMID:21685225

    Anticoagulation with heparin has been the standard management therapy of deep vein thrombosis during pregnancy. Pregnancy is generally considered as a contraindication for thrombolysis. However, anticoagulation therapy alone does not protect the limbs from post-thrombotic syndrome and venous valve insufficiency. Catheter-directed thrombolysis, combined with angioplasty and stenting, can remove the thrombus and restore patency of the veins, resulting in prevention of post-thrombotic syndrome and valve insufficiency. We report successful catheter-directed thrombolysis and stenting in two early gestation patients with a deep vein thrombosis of the left lower extremity.

  9. Indication and efficacy of intra-arterial thrombolysis for occlusion of vertebrobasilar artery in the acute stage using stroke MRI

    International Nuclear Information System (INIS)

    This study was undertaken to evaluate indication and efficacy of intra-arterial thrombolysis for 20 consecutive patients with vertebrobasilar artery occlusion by stroke MRI findings, including diffusion weighted imaging (DWI) and MR angiography in the acute stage. The age ranged from 41 to 87 years old (a mean of 69.0). National Institutes of Health Stroke Scale (NIHSS) distributed between 1 and 28 (a mean of 11.4). All patient underwent stroke MRI examination before the treatment. We established new DWI scoring, depending on the infarction size and location, from one to five points. One point was given for brain stem infarction less than 0.5 cm, two points between 0.5 cm and 1 cm, and three points for more than 1 cm in greatest diameter of brain stem blight signal. If the infarcts were located cerebellum, thalamus or occipital lobe, one point was given for single ischemic lesion and two points for two or more lesions. Revascularization was obtained in 12 of 14 patients by intra-arterial thrombolysis, urokinase administration with or without balloon angioplasty in the acute stage. One patient who failed to have recanalization deceased. Average DWI score before treatment was 2.4 in 12 patients with recanalization group, 2.0 in 2 patients with non-recanalization group, and 1.7 in 5 patients with conservative treatment group. In 14 patients with endvascular treatment group, average DWI score in patients with modified Rankin Scale (mRS) 0-2 at 90 days was 1.17±1.07, whereas the score in patients with mRS 3-6 was 3.25±1.09 (p=0.006). Our results suggest that the new DWI score could be the good predictor to evaluate the indication and efficacy of intra-arterial thrombolysis for occlusion of vertebrobasilar artery in the acute stage.

    Objective: To discuss the efficacy and safety of catheter-directed thrombolysis in treating acute lower limb ischemia. Methods: During the period from October 2009 to October 2012, 30 patients with acute lower limb ischemia were admitted to authors' hospital and received catheter-directed thrombolysis. The clinical data were retrospectively analyzed. Results: Direct effective response was obtained in 24 patients. Fogarty catheter embolectomy under DSA monitoring had to be carried out in 2 patients as they failed to respond catheter-directed thrombolysis. Two patients underwent amputation as a result of irreversible limb necrosis. One patient died from acute myocardial infarction. One patient died from multiple organs dysfunction caused by the absorption of toxins from the putrid limb. Conclusion: As a kind of minimally- invasive technique for acute lower limb ischemia, catheter-directed thrombolysis is safe and effective. (authors)

  13. Hemorrhagic transformation in ischemic stroke and its treatment during thrombolysis

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available Haemorrhagic transformation (HT of brain infarction or hemorrhagic infarction is a complication of acute ischemic stroke, especially in cardioembolic stroke, and represents the most feared complication of thrombolysis. HT is a multifocal secondary bleeding into brain infarcts with innumerable foci of capillary and venular extravasation either remaining as discrete petechiae or emerging to form confluent purpura. HT is evidenced as a parenchymal area of increased density within an area of low attenuation in a typical vascular distribution on non-contrasted CT scans and is subdivided into two major categories on the basis of standardised definition: haemorrhagic infarct (HI and parenchymal haematoma (PH. PH has been associated to poor outcome in ischemic stroke patients. Thus, its prevention, early detection and adequate treatment represent key points in the management of acute stroke.

  15. Intra-arterial thrombolysis in acute embolic stroke

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy and safety of intra-arterial thrombolysis in acute embolic stroke (AES). Methods: 21 patients with AES were undertaken urokinase or recombinated tissue plasminogen activator through percutaneous femoral intraarterial thrombolysis (IAT) as the treated group, and another 42 patients without thrombolytic treatment were assigned as the control group, which were matched to the baseline National Institutes of Health Stroke Scale (NIHSS) scores with selected gender and age. 24 h NIHSS scores, 90 d modified Rankin Scale (mRS) scores, incidences of hemorrhagic transformation (HT) and mortalities of the two groups were compared after the treatment. Results: (1) The results of cerebral angiography showed that the total re-perfusion rate was 61.90%. The middle cerebral artery (MCA), the internal carotid artery (ICA) and the basilar artery (BA) re-perfusion rates were 83.33%, 28.57% and 50.00%, respectively. (2) The NIHSS scores after 24 h were lower in the treated (IAT) group than those in the control group (12.05±5.61 vs, 14.83±4.05, P<0.05). A favorable outcome (mRS of 0-2) was more frequently observed in the 1AT group (66.67%) than that in the control group (35.71%, P<0.05). (3) There was no significant difference between the rates of HT (28.57% vs. 16.77%) and also the similar mortality rates (19.05% vs. 16.67%) not significant between the two groups. No patient died of HT in both two groups. Conclusion: IAT may be an effective treatment for AES with comparative safety. (authors)

  19. Transcatheter thrombolysis treatment for acute thrombosis in arteriovenous fistulas in hemodialysis patients

    International Nuclear Information System (INIS)

    Objective: To assess the clinical value of transcatheter thrombolysis in treating acute arteriovenous fistula thrombosis in hemodialysis patients and to discuss its technical points. Methods: During the period from Jan. 2008 to Jan. 2011, 67 times of acute arteriovenous fistula thrombosis occurred in 50 hemodialysis patients. The diagnosis was confirmed by angiographic findings. First the guide-wire was inserted and pushed forward to pass through the thrombus, then bolus injection (pulse spray) of urokinase (250000 units) through catheter was performed. If the thrombus could not be cleared away, transcatheter micro-pump continuous infusion of urokinase was employed for 1-3 days until the thrombosis was completely dissolved, which was confirmed by angiographic re-examination at 24, 48 and 72 hours after the start of thrombolysis. Results: Of the total 67 times of acute arteriovenous fistula thrombosis, the arteriovenous fistula reopened in 8 cases after transcatheter thrombolysis with pulse spray of urokinase. At 24, 48 and 72 hours after the initiation of thrombolysis treatment, the thrombus was completely dissolved in 34, 18 and 5 cases, respectively. The thrombolysis treatment failed in two cases. No serious complications such as pulmonary embolization, hemorrhage, etc. occurred during the therapeutic course. Conclusion: For the treatment of acute arteriovenous fistula thrombosis in hemodialysis patients, transcatheter thrombolysis is an easily-manipulated, effective, minimally-invasive and safe technique. Therefore, it is of great clinical value. (authors)

    The increasing complexity of procedures in the intensive care unit (ICU) requires complex software services, to reduce improper use of antibiotics and inappropriate therapies, and to offer earlier and more accurate detection of infections and antibiotic resistance. We investigated whether web-based software can facilitate the computerization of complex medical processes in the ICU. The COSARA application contains the following modules: Infection overview, Thorax, Microbiology, Antibiotic therapy overview, Admission cause with comorbidity and admission diagnosis, Infection linking and registration, and Feedback. After the implementation and test phase, the COSARA software was installed on a physician's office PC and then on the bedside PCs of the patients. Initial evaluation indicated that the services had been integrated easily into the daily clinical workflow of the medical staff. The use of a service oriented architecture with web service technology for the development of advanced decision support in the ICU offers several advantages over classical software design approaches.

  1. Catheter-Directed Thrombolysis with Percutaneous Rheolytic Thrombectomy Versus Thrombolysis Alone in Upper and Lower Extremity Deep Vein Thrombosis

    International Nuclear Information System (INIS)

    Purpose. To compare the efficacy of catheter-directed thrombolysis (CDT) alone versus CDT with rheolytic percutaneous mechanical thrombectomy (PMT) for upper and lower extremity deep vein thrombosis (DVT). Methods. A retrospective cohort of consecutive patients with acute iliofemoral or brachiosubclavian DVT treated with urokinase CDT was identified, and a chart review was conducted. Demographic characteristics, treatment duration, total lytic dose, clot lysis rates and complications were compared in patients treated with urokinase CDT alone or combined CDT and rheolytic PMT. Results. Forty limbs in 36 patients were treated with urokinase CDT alone. Twenty-seven limbs in 21 patients were treated with urokinase CDT and rheolytic PMT. The mean treatment duration for urokinase CDT alone was 48.0 ± 27.1 hr compared with 26.3 ± 16.6 hr for urokinase CDT and rheolytic PMT (p = 0.0004). The mean urokinase dose required for CDT alone was 5.6 ± 5.3 million units compared with 2.7 ± 1.8 million units for urokinase CDT with rheolytic PMT (p = 0.008). Complete clot lysis was achieved in 73% (29/40) of DVT treated with urokinase CDT alone compared with 82% (22/27) treated with urokinase CDT with rheolytic PMT. Conclusion. Percutaneous CDT with rheolytic PMT is as effective as CDT alone for acute proximal extremity DVT but requires significantly shorter treatment duration and lower lytic doses. Randomized studies to confirm the benefits of pharmacomechanical thrombolysis in the treatment of acute proximal extremity DVT are warranted

    To evaluate the venous patency in patients treated by catheter-directed thrombolysis with low-dose urokinase (UK) for symptomatic lower extremity deep venous thrombosis (DVT). Eighty-nine consecutive patients (46 women and 43 men; mean age, 58.1 years), treated by catheter-directed thrombolysis with low-dose UK were included in this study. Immediate venous patency was evaluated in terms of technical success (successful restoration of antegrade in-line flow in the treated vein with residual stenosis rate of less than 30%) and clinical success (significant reduction of clinical symptoms before hospital discharge). Late venous patency was evaluated in terms of primary patency rate and clinical success. Immediate technical success was achieved in all patients and immediate clinical success in 80 (90%) patients. There was no major systemic bleeding complication. The primary patency rate at 6 months and 12 months was 84% and 79%, respectively. Fifty-six (63%) patients were asymptomatic after a median clinical follow-up of 18 months, eleven (12%) patients improved moderately, seven (8%) patients remained unchanged, and fifteen (17%) patients had no clinical follow-up. Short-term catheter-directed thrombolysis with low-dose UK can be an effective, safe method to manage DVT of the lower extremities.

    BACKGROUND There is little data comparing catheter-directed thrombolysis (CDT) via small saphenous veins vs. systematic thrombolysis on complications and efficacy in acute deep venous thrombosis patients. The aim of our study was to compare the efficacy and safety of CDT via the small saphenous veins with systematic thrombolysis for patients with acute deep venous thrombosis (DVT). MATERIAL AND METHODS Sixty-six patients with acute DVT admitted from June 2012 to December 2013 were divided into 2 groups: 27 patients received systemic thrombolysis (ST group) and 39 patients received CDT via the small saphenous veins (CDT group). The thrombolysis efficiency, limb circumference differences, and complications such as post-thrombotic syndrome (PTS) in the 2 groups were recorded. RESULTS The angiograms demonstrated that all or part of the fresh thrombus was dissolved. There was a significant difference regarding thrombolysis efficiency between the CDT group and ST group (71.26% vs. 48.26%, P=0.001). In both groups the postoperative limb circumference changes were higher compared to the preoperative values. The differences between postoperative limb circumferences on postoperative days 7 and 14 were significantly higher in the CDT group than in the ST group (all P<0.05). The incidence of postoperative PTS in the CDT group (17.9%) was significantly lower in comparison to the ST group (51.85%) during the follow-up (P=0.007). CONCLUSIONS Catheter-directed thrombolysis via the small saphenous veins is an effective, safe, and feasible approach for treating acute deep venous thrombosis. PMID:27552357

    A number of barriers to the implementation of evidence-based practice have already been inventoried. However, little attention has been given to their context-specific nature. This qualitative evidence synthesis examines commonalities in the obstacles perceived by different groups of health care practitioners working in the Belgian health care system and sets out to discuss potential strategies to bridge some of these barriers. We actively searched for primary studies addressing our topic of interest in international and national databases (1990 to May 2008), consulted experts and screened references of retrieved studies. We opted for the meta-aggregative approach, developed by the Joanna Briggs Institute, to analyse our findings. The findings indicate that (1) evidence might have a limited role in decision-making processes; (2) aspects other than quality of care steer the evidence-based practice agenda; (3) some health care providers benefit less from evidence-based practice than others and (4) there is a lack of competences to put the evidence-based principles in practice. Belgian policy makers might consider health care system characteristics from and strategies developed or suggested by others to respond to country-specific obstacles. Examples include but are not limited to; (a) providing incentives for patient-centred care coordination and patient communication, (b) supporting practitioners interested in applying research-related activities, (c) considering direct access systems and interprofessional learning to respond to the demand for autonomous decision-making from satellite professional groups, (d) systematically involving allied health professionals in important governmental advisory boards, (e) considering pharmaceutical companies perceived as 'the enemy' an ally in filling in research gaps, (f) embedding the evaluation of evidence-based knowledge and skills in examinations (g) moving from (in)formative learning to transformative learning and (h

    Many factors are necessary for obtaining satisfactory results after catheter-directed thrombolysis (CDT) for iliofemoral deep venous thrombosis (DVT). Selections of patients, composition of the thrombolytic fluid, anticoagulation per- and post-procedural, recognition and treatment of persistent obstructive lesions of the iliac veins are the most important contributors. Stenting has been known for 15 to 20 years. The first publication on CDT in 1991 was combined with ballooning the iliac vein, an additive procedure which has been abandoned as an isolated procedure. This chapter will discuss selection, indication, such as an iliac compression syndrome, and outcome of iliac stenting in combination with CDT. The reported frequency of stenting used after CDT is very inconsistent, therefore this will be discussed in details. It is concluded that selection for stenting is of the greatest importance, when CDT is used for iliofemoral DVT, but strict criteria for stenting are not available in the existing literature. The potential value of intravascular ultrasound (IVUS) is also discussed. PMID:24843096

    The study was to investigate thrombolysis in vitro with ultrasound, and to discuss effects of thrombolysis with ultrasound on the structure of erythrocyte and its safety threshold under different ultrasound intensity and exposure time. The structure of erythrocyte in thrombus was evaluated under light microscope. The relationship between the structure of erythrocyte in thrombus and ultrasound intensity and exposure time was obtained. The results showed that ultrasound eliminated the thrombus. According to the change of the structure of erythrocyte in thrombus and ultrasound intensity and exposure time, the effects of thrombolysis with ultrasound could be divided into three kinds of areas: the A, B, C area. The area A was the safe area, the area B was the relatively safe area, and the area C was the irreversible damage area. The study suggested that ultrasound intensity and exposure time had significant impact on the structure of erythrocyte. Stronger ultrasound intensity or longer exposure time could cause erythrocytes irreversible damage. It could accelerate thrombolysis and shorten the exposure time that the ultrasound intensity was little bit increased. The study of effects of thrombolysis with ultrasound on the structure of erythrocyte and its safety threshold were important for practical applications.

  10. Lesion patterns in successful and failed thrombolysis in middle cerebral artery stroke

    International Nuclear Information System (INIS)

    Thrombolysis has been shown to improve neurological recovery in acute stroke. But the response to thrombolysis is variable across patients. We sought to investigate this variability by analyzing the lesion patterns following systemic thrombolysis with recombinant tissue plasminogen activator (rtPA) and tirofiban in middle cerebral artery (MCA) stroke. One hundred three consecutive stroke patients (67 ± 14 years) were grouped according to the site of MCA occlusion and successful or failed recanalization as assessed with magnetic resonance angiography. Infarct lesions were analyzed in T2-weighted magnetic resonance images after 10 days. Patients recovered markedly upon successful recanalization following thrombolysis (p < 0.05) but remained severely impaired when there was no recanalization within 24 h. Infarct lesions were smaller after successful than after failed recanalization (p < 0.005). They occurred throughout the cerebral cortex on the cerebral convexity in distal MCA occlusions with large individual heterogeneity. In contrast, there was a large lesion overlap in insular cortex, basal ganglia, internal capsule, and paraventricular white matter in proximal MCA occlusions. Systemic thrombolysis with rtPA and tirofiban of MCA occlusions resulted in early neurological recovery and preferentially peri-insular infarcts. In failed recanalization of the MCA stem there was a large lesion overlap in the hemispheric white matter and a lack of recovery. (orig.)

    Our objective was to evaluate the effect of anticoagulation on cardioembolic stroke (CS) severity, outcomes, and response to intravenous thrombolysis (IVT). Observational study of CS patients admitted to a Stroke Center (2010-2013). The sample was classified into three groups based on pre-stroke oral anticoagulants (OAC) treatment (all acenocumarol) and the international normalized ratio (INR) on admission: (1) non-anticoagulated or anticoagulated patients with INR mRS). Overall 475 patients were included, 47.2 % male, mean age 75.5 (SD 10.7) years old, 31.8 % were on OAC. 76 % belonged to the INR 2. 35 %of patients received IVT. Multivariate analyses showed that an INR ≥2 on admission was a factor associated with a higher probability of mild stroke (NIHSS mRS ≤2). OAC was not related to stroke outcomes in the subgroup of IVT patients. Therapeutic OAC levels are associated with lesser CS severity, and prior OAC treatment with favorable outcomes. In this study, OAC are not related with response to IVT. PMID:26860861

  13. Thrombolysis of the basilar artery: 5-year results from the Saarland stroke registry

    International Nuclear Information System (INIS)

    Acute thrombosis of the basilar artery has a fatal outcome if left untreated. The relatively good prognosis with intra-arterial thrombolysis makes it the therapy of choice for acute basilar thrombosis. In the Saarland stroke registry, we analyzed 47 patients with angiographically proven basilar artery thrombosis within the last 5 years. We observed a better outcome in patients with good income, with recanalization, and a short time between onset of symptoms and start of thrombolysis. The complications, such as intracerebral bleedings, occurred only in the group treated with rt-PA. Intra-arterial thrombolysis with urokinase or rt-PA is a relatively safe therapy, but should be performed in neuroradiological centers. With progressing symptoms the therapeutic window can be stretched up to 12 h, but coma lasting for more than 4 h is related to a bad outcome. (orig.)

    Alteplase is the only approved drug for the treatment of acute ischemic stroke, but it is offered to a minority of patients, not only because of the short therapeutic window but also because of the numerous contraindications associated with thrombolysis, such as thrombocytopenia. There is some controversy on the true risk associated with thrombolysis in patients with thrombocytopenia. Here we report the case of a young patient, who developed an in-hospital acute ischemic stroke involving a large territory of the right middle cerebral artery, who was successfully treated with intravenous alteplase, despite having thrombocytopenia and prolonged prothrombin times due to systemic lupus erythematosus and antiphospholipid syndrome. This case exemplifies the need to reassess contraindications for thrombolysis, many based on expert opinion and not clinical evidence, especially in complex clinical situations. PMID:26575492

    Objective The coronary anatomic feature and development after thrombolysis in acute myocardial infarction (AMI) were studied.Mehtods 100 patients with AMI received urokinase and strepokinase. Coronary angiography (CAG) was performed at 90 minuts and again at 3 to 4 weeks.Results Successful thrombolysis occurred in 60 cases,but failed in 40. The ratio of reperfusion was 60%.CAG showed there were residual thrombi in 84 patients (84%) and complete coronary occlusion in 40(40% ).Angiography at 3 to 4 weeks after thrombolysis showed the stenosis worsened in 8 patients and improved in 10.Conclusion AMI is caused by sudden coronary thrombotic occlusion and can be repeffused by using thrombolytic agent or mechanical methods. Thrombolytic agents usually can not resolve thrombi completely. So percutaneous transluminal coronary angiography (PTCA) is recommended as an important method to improve serious residual stenosis.

    Our objective was to estimate the saving of life by thrombolysis and resuscitation in acute myocardial infarction (AMI) before and after hospital admission. We studied all 1516 patients admitted to a Scottish teaching hospital in 1990 and 1992 who had a final diagnosis of AMI, and 311 patients enrolled in the Grampian region early anistreplase trial (GREAT). Cardiac arrest occurred in 250/1516 (16%) hospital patients. Of these, 77 (31%) were discharged alive--a saving of 51 lives per thousand cases. 797 (53%) patients received thrombolysis, of whom 114 (14%) died. Assuming the same relative reduction in mortality as in the second international study of infarct survival (ISIS-2; 23%), 34 lives were saved by thrombolytic therapy, representing 22 lives per thousand cases. Of 311 patients in GREAT, 15 (5%) had prehospital cardiac arrest, with 7 patients surviving to discharge (48%)--a saving of 23 lives per thousand cases. Those patients given domiciliary thrombolysis had a one month mortality of 6.7% (11/163) compared with 12.2% (18/148) for those receiving hospital thrombolysis--a saving of 55 lives per thousand cases for prehospital thrombolysis. This is additional to 28 lives per thousand estimated for thrombolytic therapy in hospital, totalling 83 lives saved per thousand cases of AMI receiving thrombolytic therapy prehospital. In hospital, more lives were saved by resuscitation than by thrombolytic therapy, but this ratio was reversed in the period before hospital admission. These results emphasise the paramount importance of resuscitation in hospital, and the enhanced efficacy of thrombolysis when given at the earliest opportunity. PMID:7607764

  18. Magnetic Resonance Imaging Results Can Affect Therapy Decisions in Hyperacute Stroke Care

    International Nuclear Information System (INIS)

    Background: Despite some limitations, a perfusion/diffusion mismatch can provide a working estimate of the ischemic penumbra in hyperacute stroke and has successfully been used to triage patients. Purpose: To evaluate whether the addition of magnetic resonance imaging (MRI) to clinical and non-contrast computed tomography (CT) data alters diagnosis and choice of therapy. Material and Methods: We retrospectively analyzed clinical records, and CT and MRI data fully available in 97 of 117 patients. Upon clinical examination and CT, a diagnosis and treatment path was scored and compared to treatment path after addition of MRI data. The MRI protocol included T2-weighted images, diffusion-weighted images (DWI), and perfusion-weighted images (PWI), and MR angiography (MRA). Results: MRI data were acquired in less than 15 min. In 20 of 97 patients (21%), the diagnosis changed after MRI. In 25 of 97 patients (26%), the presumptive treatment plan was changed after MRI evaluation. Thirteen patients had their treatment changed from thrombolytic to nonthrombolytic therapy. Three patients were changed from nonthrombolytic to intraarterial (IA) thrombolysis. In one patient, treatment was changed from intravenous (IV) to IA thrombolysis, and in five patients it was changed from IA to IV thrombolysis. In two patients, systemic heparin was added to antiplatelet therapy. Conclusion: The expansion of the acute stroke protocol to include MRI altered the therapy plan in 26% of our patients. The utility of MRI, shown here to improve patient stratification into best-treatment options, demonstrates the value of using MRI to optimize care in hyperacute stroke patients

    Full Text Available Abstract Background Atherothrombotic diseases such as myocardial or cerebral infarction are serious consequences of the thrombus formed in blood vessels. Thrombolytic agents are used to dissolve the already formed clots in the blood vessels; however, these drugs have certain limitations which cause serious and sometimes fatal consequences. Herbal preparations have been used since ancient times for the treatment of several diseases. Herbs and their components possessing antithrombotic activity have been reported before; however, herbs that could be used for thrombolysis has not been reported so far. This study's aim was to investigate whether herbal preparations (aqueous extract possess thrombolytic activity or not. Methods An in vitro thrombolytic model was used to check the clot lysis effect of six aqueous herbal extracts viz., Tinospora cordifolia, Rubia cordifolia, Hemidesmus indicus, Glycyrrhiza glabra Linn, Fagonia Arabica and Bacopa monnieri Linn along with Streptokinase as a positive control and water as a negative control. Results Using an in vitro thrombolytic model, Tinospora cordifolia, Rubia cordifolia, Hemidesmus indicus, Glycyrrhiza glabra Linn, Fagonia Arabica and Bacopa monnieri Linn showed 19.3%, 14.5%, 20.3%, 17.8%, 75.6% and 41.8% clot lysis respectively . Among the herbs studied Fagonia arabica showed significant % of clot lysis (75.6% with reference to Streptokinase (86.2%. Conclusion Through our study it was found that Dhamasa possesses thrombolytic properties that could lyse blood clots in vitro; however, in vivo clot dissolving properties and active component(s of Dhamasa for clot lysis are yet to be discovered. Once found Dhamasa could be incorporated as a thrombolytic agent for the improvement of patients suffering from Atherothrombotic diseases.

  2. Comparing study with two venous approaches of antegrade catheterization for thrombolysis in acute iliofemoral deep vein thrombosis

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical effectiveness of catheterization via the great saphenous vein for thrombolysis in acute iliofemoral deep vein thrombosis (IFVT). Methods: Patients with documented acute iliofemoral deep vein thrombosis were divided into two groups. Patients in group A received CDT with venous access through the ipsilateral great saphenous vein. The patients in group B received CDT via the ipsilateral popliteal vein. Clinical efficacy was evaluated by measuring the circumferences between the normal and affected limbs before and after treatment; the venous patency score, the rate of patency improvement based on venographic results; and the clinical results including the limbs edema reduction rate, the mean punctuation duration and complications; were all compared between the two groups. Results: The total effective rates between group A and group B showed no significant difference (95.2% vs 96%, P = 0.549); including the limbs edema reduction rates(86.6 ± 20.0% vs 85.7 ± 14.6%, P=0.868), likewise, the rates of venous patency improvement(57.9 ± 19.4% vs 57.7 ± 19.3%, P=0.968). The mean punctuation duration of group A was remarkable less than that of group B (7.3 minutes vs 16.7 minutes, P<0.05). The incidence of complications at the site of insertion in group A was lower than that in group B (P<0.05). Conclusions: The great saphenous vein is a new alternative access site for antegrade catheterization in catheter-directed thrombolysis for treatment of acute IFVT; more convenient and safe than popliteal venous approach.

  3. Recombinant Tissue Plasminogen Activator Induces Neurological Side Effects Independent on Thrombolysis in Mechanical Animal Models of Focal Cerebral Infarction: A Systematic Review and Meta-Analysis.

    Directory of Open Access Journals (Sweden)

    Mei-Xue Dong

    Full Text Available Recombinant tissue plasminogen activator (rtPA is the only effective drug approved by US FDA to treat ischemic stroke, and it contains pleiotropic effects besides thrombolysis. We performed a meta-analysis to clarify effect of tissue plasminogen activator (tPA on cerebral infarction besides its thrombolysis property in mechanical animal stroke.Relevant studies were identified by two reviewers after searching online databases, including Pubmed, Embase, and ScienceDirect, from 1979 to 2016. We identified 6, 65, 17, 12, 16, 12 and 13 comparisons reporting effect of endogenous tPA on infarction volume and effects of rtPA on infarction volume, blood-brain barrier, brain edema, intracerebral hemorrhage, neurological function and mortality rate in all 47 included studies. Standardized mean differences for continuous measures and risk ratio for dichotomous measures were calculated to assess the effects of endogenous tPA and rtPA on cerebral infarction in animals. The quality of included studies was assessed using the Stroke Therapy Academic Industry Roundtable score. Subgroup analysis, meta-regression and sensitivity analysis were performed to explore sources of heterogeneity. Funnel plot, Trim and Fill method and Egger's test were obtained to detect publication bias.We found that both endogenous tPA and rtPA had not enlarged infarction volume, or deteriorated neurological function. However, rtPA would disrupt blood-brain barrier, aggravate brain edema, induce intracerebral hemorrhage and increase mortality rate.This meta-analysis reveals rtPA can lead to neurological side effects besides thrombolysis in mechanical animal stroke, which may account for clinical exacerbation for stroke patients that do not achieve vascular recanalization with rtPA.

    We examined the relationship between an early spontaneous type V blood pressure fluctuation and the post-thrombolysis prognosis of patients with acute cerebral infarction. Patients were admitted consecutively. All patients were categorized into the type V blood pressure fluctuation group or non-type V blood pressure group. Their blood pressure was monitored before thrombolysis and until 6 h after thrombolysis. Baseline data and clinical outcomes were compared. Of 170 patients, 43 (25.2%) had an early type V blood pressure fluctuation. The National Institute of Health Stroke Scale (NIHSS) score before thrombolysis and 24 h after thrombolysis, and the modified Rankin scale score at 90 days differed significantly between the two groups (P V blood pressure fluctuation is common in patients with acute cerebral infarction who received venous thrombolysis, especially if they have a higher NIHSS score before thrombolysis. The type V blood pressure fluctuation may not influence patients' prognosis; however, this needs to be confirmed in future trials. PMID:27278121

  5. Is the attenuation of thromboembolic vascular occlusions a criterion for the prognosis of thrombolysis?

    International Nuclear Information System (INIS)

    Purpose: To test whether the prognosis of systemic thrombolysis can be estimated with the attenuation values of vascular occlusions as measured with multi-slice computed tomography (MSCT). Methods: Prior to thrombolysis with rt-PA, the attenuation values of vascular occlusions were determined with a helical MSCT using a collimation of 0.5 mm. We examined 5 patients that were 63 - 79 years old. With the help of reference values that were obtained from a phantom study we categorised the vascular occlusions according to their attenuation values as being mixed thrombi with low or high proportions of erythrocytes, or red thrombi. TOF angiographies were done before and after the thrombolytic therapy. Results: The systemic therapy with rt-PA was effective in vascular occlusions that had attenuation values of red thrombi or of mixed thrombi with a high proportion of erythrocytes. The therapy showed no effect when the attenuation values matched with mixed thrombi with a low proportion of erythrocytes. Due to artefacts that were caused by beam hardening, attenuation measurements could not be performed in the posterior fossa. Conclusion: The presented cases are in accordance with the results of experimental studies which indicate that the efficacy of thrombolysis increases with the attenuation values of thromboembolic vascular occlusions. The predictive value of attenuation measurements by MSCT for the prognosis of systemic thrombolysis cannot be given yet. (orig.)

  6. Sustained thrombolysis with DNA-recombinant tissue type plasminogen activator in rabbits

    International Nuclear Information System (INIS)

    Tissue type plasminogen activator (t-PA) is an effective thrombolytic agent in experimental animals. The duration of the thrombolytic effect of infused t-PA is unknown. The authors compared the duration of the thrombolytic effect of t-PA with streptokinase by measuring the lysis of 125I-fibrin-labeled thrombi in rabbit jugular veins at different times after a bolus injection of the fibrinolytic agents. The pharmacodynamics of both thrombolytic agents were determined in rabbits using a sensitive ex vivo fibrinolytic assay. Streptokinase and t-PA were given as a bolus dose of 15,000 U/kg. There was no detectable circulating fibrinolytic activity 30 minutes after the bolus dose of t-PA and 120 minutes after the bolus dose of streptokinase. The t-PA injection produced 34% thrombolysis at 30 minutes, 90% thrombolysis at 120 minutes, and 96% thrombolysis at 240 minutes. The streptokinase injection produced 17% thrombolysis at 30 minutes, 34% at 120 minutes, and 34% at 240 minutes. These observations indicate that the thrombolytic effect of t-PA is sustained beyond its time of clearance from the circulation whereas the thrombolytic effect of streptokinase closely parallels its activity in the circulation

  7. Transcatheter thrombolysis treatment of acute A-V internal fistula thrombogenesis in hemodialysis patients

    International Nuclear Information System (INIS)

    Objective: To investigate the value of transcatheter thrombolysis treatment of acute A-V internal fistula thrombogenesis in hemodialysis patients. Methods: The acute A-V fistula thrombogenesis in 32 hemodialysis patients with chronic renal failure were treated with transcatheter pulse-spray pharmacomechanical thrombolysis (PSPMT). Results: Acute A-V fistula thrombogenesis was verified in all 32 patients by angiography and treated with transcatheter PSPMT. the immediate clinical success rate of thrombolysis was achieved in 97% except for one case. The A-V fistulas were proved to reopen by post-treatment angiography. Recurrent thrombosis was found in 4 cases, reopening with transcatheter PSPMT was achieved in 2 of them and the rest 2 cases were undergone PTA because of localized vascular stenosis. All the 32 A-V fistulae were reopened after treatment without serious complications such as hemorrhage, pulmonary embolism and others. Conclusions: Transcatheter PSPMT is a safe, effective and microinvasive treatment for acute A-V fistula thrombolysis with higher immediate reopening rate. Transcatheter PSPMT combined with PTA and intravascular stent grafting can improve long-term patency rate

  11. Inter-arterial thrombolysis using rt-PA for acute cerebral ischemic stroke

    International Nuclear Information System (INIS)

    Objective: To evaluate the safety and efficacy of intra-arterial thrombolysis in patients with acute cerebral ischemic stroke. Methods: Twenty-one patients with acute internal carotid circulation infraction (internal carotid 3, MCA 12, ACA 5, lenticulostriate in 1)were treated with intra-arterial thrombolysis of recombinant tissue plasminogen activator (rt-PA)which was performed within 2-6 hours of symptom onset. Recanalization was observed during the operation. Intracerebral hemorrhage (ICH)was monitored immediately and 24 h after the treatment by CT or MRI scanning. Chinese stroke scale was used to evaluate the recovery of neurological functions pre-operatively and 30 d after the treatment. Results: All the 21 patients were 100% success in receiving intra-arterial thrombolysis technique and revealed 16 having the degree of recanalization of 2 to 3 grade as regards to TMI, 16 patients degree of recanalization reached 2 to 3 grade according to TMI; 5 patients showed 1 to 2 grade. Symptomatic ICH was observed in 3 patients, with two dead. Arterial dissection was found in one patient. Thirty days after the operation, 17 patients' cerebral function reduced over 50 percent; 2 less than 50 percent; and 2 died. The patients achieved 2 to 3 grade of recanalization were obviously getting better than those achieving 0 to 1 grade. Conclusions: It is adapt to have intra-arterial thrombolysis with six hours from onset; but still have the danger of severe ICH. The treatment should be started as early as possible. (authors)

    Thrombus formation is a recognised complication of IVC filter placement, however IVC and bilateral renal vein occlusion secondary to thrombus is much less common. We present a case of infrahepatic caval and bilateral renal vein occlusion secondary to thrombosis of a suprarenal IVC filter. With progressive clinical deterioration and failure of conservative medical management the patient underwent successful mechanical disruption and catheter directed thrombolysis.

  13. Trans-jugular catheter-directed thrombolysis combined with trans-dorsalis pedis vein thrombolysis for the treatment of deep venous thrombosis of the lower limbs

    International Nuclear Information System (INIS)

    Objective: To investigate the feasibility and efficacy of trans-jugular catheter-directed thrombolysis (CDT) together with trans-dorsalis pedis vein thrombolysis for the treatment of deep venous thrombosis (DVT) of the lower limbs. Methods: Jugular vein puncture, indwelling catheter and placement of IVC filter were performed in 18 patients with DVT (study group) followed by continuous trans-jugular CDT together with trans-dorsalis pedis vein thrombolysis. During the corresponding period, 16 patients with DVT (control group) received trans-dorsalis pedis vein thrombolysis only. Results: The thrombolytic time and total dose of urokinase in study group and control group were (6.6 ± 2.3) days, (5.52 ± 2.24) x 106 units and (8.2 ± 1.4) days, (7.00 ± 1.66) x 106 units respectively. The thrombolytic time and total dose of urokinase in study group were significantly lower than that in control group (P < 0.05). After the treatment the thigh circumference and calf circumference in study group showed a reduction of (4.6 ± 2.1) cm and (4.0 ± 2.1) cm respectively, which were (3.2 ± 1.7) cm and (2.7 ± 1.5) cm respectively in control group, the difference between two groups was statistically significant (P < 0.05). The complete patent of the veins was 66.7% in study group and 31.3% in control group, the difference between two groups was significant (P < 0.05). In four cases of the study group, the filters were withdrawn through the original puncture site after the thrombus was completely dissolved. Conclusion: Trans-jugular CDT combined with trans-dorsalis pedis vein thrombolysis is an effective and safe therapeutic technique for the treatment of deep venous thrombosis of the lower extremities, moreover, the filter can be taken back via the original puncture site when the thrombus is completely dissolved.

    2006-01-01

    Purpose: To determine the economic efficiency of a whole-radiology in- and outpatient treatment with angiographic interventions performed as the main or sole therapy. Materials and Methods: The calculations represent the data of a university radiology department, including the following angiographic interventions (neuroradiology not considered): Vascular intervention (PTA, stent implantation) of kidneys and extremities, recanalization of hemodialysis access, chemoembolization, diagnostic arterioportal liver CT, port implantation, varicocele embolization, PTCD, percutaneous implantation of biliary stent. First, the different angiographic interventions are categorized with reference to the German DRG system 2005. Considering the example of a university hospital, the individual cost of each intervention is calculated and correlated with reimbursements by G-DRG2005 and so-called ''ambulant operation'' (EBM200plus). With these data, profits and losses are calculated for both in- and outpatient care. Results: Radiologic interventions of inpatients yield a profit in the majority of cases. With a base rate of 2900 Euro, the profits in our university hospital range between -872 Euro and +3411 Euro (mean: +1348 Euro). On the other hand, those angiographic interventions suitable for ''ambulant operation'' generate average profits of +372 Euro, if only direct costs are considered. The data of outpatient radiological interventions average between 381 Euro up to 1612 Euro lower than compared with profits obtained from in patient care. (orig.)

    High intensity focused ultrasound (HIFU) based thrombolysis has emerged as a promising drug-free treatment approach for ischemic stroke. The large amount of acoustic power required by this approach, however, poses a critical challenge to the future clinical translation. In this study, multi-frequency acoustic waves at MHz range (near 1.5 MHz) were introduced as HIFU excitations to reduce the required power for treatment as well as the treatment time. In vitro bovine blood clots weighing around 150 mg were treated by single-frequency and multi-frequency HIFU. The pulse length was 2 ms for all experiments except the ones where the duty cycle was changed. It was found that dual-frequency thrombolysis efficiency was statistically better than single-frequency under the same acoustic power and excitation condition. When varying the acoustic power but fixing the duty cycle at 5%, it was found that dual-frequency ultrasound can save almost 30% power in order to achieve the same thrombolysis efficiency. In the experiment where the duty cycle was increased from 0.5% to 10%, it was shown that dual-frequency ultrasound can achieve the same thrombolysis efficiency with only half of the duty cycle of single-frequency. Dual-frequency ultrasound could also accelerate the thrombolysis by a factor of 2-4 as demonstrated in this study. No significant differences were found between dual-frequencies with different frequency differences (0.025, 0.05, and 0.1 MHz) and between dual-frequency and triple-frequency. The measured cavitation doses of dual-frequency and triple-frequency excitations were at about the same level but both were significantly higher than that of single-frequency.

    Objective To investigate the effects of delayed recanalization and thrombolysis on atrioventricular(AV) block in acute inferior myocardial infarction(AIMI).Methods A total of 212 patients, including 30 patients(group A)who underwent delayed recanalization of infarct-related artery (IRA) by PTCA within 12~18 hours after onset, 50 patients(group B) who received intravenous thrombolytic therapy within 12 hours of AIMI onset, 132 patients(group C) with AIMI who received conventional therapy, were enrolled in this study.Results In group A, the occurrence of AV block was decreased significantly (26.7% vs 6.7%, P<0.01) at 24 hours after delayed recanalization of IRA by PTCA; in group B, the occurrence rate of A-V block was also decreased significantly(24.0% vs 6.0%, P<0.01) at 24 hours after thrombolytic therapy; while in group C, 28.8% patients presented A-V block at 24 hours after admission. The occurrence of AV block was significantly lower in group A than in group C(6.7% vs 28.8%, P<0.01). Compared with group C, the inpatient mortality rate in group A was also decreased by 6.5% (3.3% vs9.8%,P>O.05).Conclusion The delayed recanalization of IRA by PTCA within 12~48 hours after the onset of AIMI can reduce the incidence of A-V block and probably decrease the in-hospital mortality rate.

    We wanted to evaluate the feasibility of catheter-directed thrombolysis with a continuous infusion of low-dose urokinase for treating non-acute (less than 14 days) deep venous thrombosis of the lower extremity. The clinical data of 110 patients who were treated by catheter-directed thrombolysis with a continuous infusion of low-dose urokinase for lower extremity deep venous thrombosis was analysed. Adjunctive angioplasty or/and stenting was performed for the residual stenosis. Venous recanalization was graded by pre- and posttreatment venography. Follow-up was performed by clinical evaluation and Doppler ultrasound. A total of 112 limbs with deep venous thrombosis with a mean symptom duration of 22.7 days (range: 15-38 days) were treated with a urokinase infusion (mean: 3.5 million IU) for a mean of 196 hours. After thrombolysis, stent placement was performed in 25 iliac vein lesions and percutaneous angioplasty (PTA) alone was done in fi ve iliac veins. Clinically significant recanalization was achieved in 81% (90 of 112) of the treated limbs: complete recanalization was achieved in 28% (31 of 112) and partial recanalization was achieved in 53% (59 of 112). Minor bleeding occurred in 14 (13%) patients, but none of the patients suffered from major bleeding or symptomatic pulmonary embolism. During followup (mean: 15.2 months, range: 3-24 months), the veins were patent in 74 (67%) limbs. Thirty seven limbs (32%) showed progression of the stenosis with luminal narrowing more than 50%, including three with rethrombosis, while one revealed an asymptomatic iliac vein occlusion: 25 limbs (22%) developed mild post-thrombotic syndrome, and none had severe post-thrombotic syndrome. Valvular reflux occurred in 24 (21%) limbs. Catheter-directed thrombolysis with a continuous infusion of low-dose urokinase combined with adjunctive iliac vein stenting is safe and effective for removal of the clot burden and for restoration of the venous flow in patients with non-acute lower

    This case report describes a patient with thromboemboli trapped in the Chiari network within the right side of the heart and resistant to thrombolysis. The right atrial masses were completely removed under cardiopulmonary bypass. Histological evaluation confirmed a mixed thromboemboli, with thrombus structures showing signs of organisation and surrounded by a fibrous capsule. The plasma level of the plasminogen activator inhibitor type-1 (PAI-1) was 50% higher than the normal upper limit. In this presented case, the Chiari network displayed a protective function but the expansion and organisation of the thromboembolus found there made it resistant to lytic treatment. Another important factor that could have influenced the resistance to thrombolysis was the high level of PAI-1. PMID:22791494

    Hermes, Robert E.; Trajkovska, Keti

    1998-05-01

    Laser thrombolysis is the controlled ablation of a thrombus (blood clot) blockage in a living arterial system. Theoretical modeling of the interaction of laser light with thrombi relies on the ability to perform in vitro experiments with well characterized surrogate materials. A synthetic thrombus formulation may offer more accurate results when compared to in vivo clinical experiments. We describe here the development of new surrogate materials based on formulations incorporating chicken egg, guar gum, modified food starch, and a laser light absorbing dye. The sound speed and physical consistency of the materials were very close to porcine (arterial) and human (venous) thrombi. Photographic and videotape recordings of pulsed dye laser ablation experiments under various experimental conditions were used to evaluate the new material as compared to in vitro tests with human (venous) thrombus. The characteristics of ablation and mass removal were similar to that of real thrombi, and therefore provide a more realistic model for in vitro laser thrombolysis when compared to gelatin.

    Unintentional intraarterial injections are rare but may have devastating consequences. No consensus on treatment has been established owing to the wide variety of possible injected substances, incomplete understanding of the underlying pathophysiology, and the absence of case-controlled, prospective human studies. The aim of the present study and literature review was to evaluate the benefit of intraarterial thrombolysis combined with systemic anticoagulation therapy when an artery of the upper extremity is accidentally punctured and ischemia of the hand ensues.

    To evaluate the efficacy of adjunctive aspiration thrombectomy for the treatment of iliofemoral deep vein thrombosis (DVT). 24 patients (9 males and 15 females; mean age, 53 years), treated by aspiration thrombectomy were enrolled in this study. The day after undergoing urokinase (UK) thrombolysis, any residual thrombus over a long segment was treated by aspiration thrombectomy using a 12 Fr long sheath. Residual short-segment (< 10 cm) iliac vein thrombus and/or stenosis were treated with a stent. The evaluation of venous patency was conducted by color Doppler ultrasonography, venography and/or computed tomography. The technical and clinical success rates were 100% and 92%, respectively. Twenty-three patients were treated by UK thrombolysis and iliac stent. The overall patency rate at 1, 2 and 3 years was 85%, 82% and 81%, respectively. Over the course of the follow-up period, occlusion was observed in 4 cases (1 acute and 3 chronic cases). Periprocedural complication occurred in 4 cases (17%) in the form of a minimal hematoma or pain on the puncture site as well as a case of pulmonary embolism at one month after treatment. The adjunctive aspiration thrombectomy with conventional thrombolysis and stent placement can be an effective and safe method in the treatment of left iliofemoral DVT

The evaluation of venous patency was conducted by color Doppler ultrasonography, venography and/or computed tomography. The technical and clinical success rates were 100% and 92%, respectively. Twenty-three patients were treated by UK thrombolysis and iliac stent. The overall patency rate at 1, 2 and 3 years was 85%, 82% and 81%, respectively. Over the course of the follow-up period, occlusion was observed in 4 cases (1 acute and 3 chronic cases). Periprocedural complication occurred in 4 cases (17%) in the form of a minimal hematoma or pain on the puncture site as well as a case of pulmonary embolism at one month after treatment. The adjunctive aspiration thrombectomy with conventional thrombolysis and stent placement can be an effective and safe method in the treatment of left iliofemoral DVT

  12. Local intra-arterial thrombolysis in the carotid territory: does recanalization depend on the thromboembolus type?

    International Nuclear Information System (INIS)

    Little is known about whether recanalization of carotid territory occlusions by local intra-arterial thrombolysis (LIT) depends on the type of the occluding thromboembolus. We retrospectively analysed the records of 62 patients with thromboembolic occlusions of the intracranial internal carotid artery (ICA) bifurcation or the middle cerebral artery who were undergoing LIT with urokinase within 6 h of symptom onset. We determined the influence of thromboembolus type (according to the TOAST criteria), thromboembolus location, leptomeningeal collaterals, time interval from onset of symptoms to onset of thrombolysis, and patient's age on recanalization. The thromboembolus type was atherosclerotic in six patients, cardioembolic in 29, of other determined etiology in four, and of undetermined etiology in 23 patients. Thirty-three (53%) thromboembolic occlusions were recanalized. The thromboembolus location but not the TOAST stroke type nor other parameters affected recanalization. In the TOAST group of patients with cardioembolic occlusions recanalization occurred significantly less frequently when transoesophageal echocardiography showed cardiac thrombus. The present study underlines the thromboembolus location as being the most important parameter affecting recanalization. The fact that thromboembolic occlusions originating from cardiac thrombi had a lower likelihood of being resolved by thrombolysis indicates the thromboembolus type as another parameter affecting recanalization.

    Anterior spinal artery syndrome (ASAS) often leads to complete motor paralysis with poor clinical outcome. There is a lack of controlled clinical trials on acute treatment strategies in ASAS. However, systemic thrombolysis with recombinant tissue-plasminogen activator (rt-PA) might be a useful therapeutic option in ASAS. We report the management of a patient with ASAS below thoracic level 10, who was treated with intravenous thrombolysis. An 81 year old patient presented with flaccid paraplegia. After exclusion of aortal dissection, spinal tumour or haemorrhage, the patient was treated with intravenous rt-PA 3 h 40 min after symptom onset. The follow up magnetic resonance imaging (MRI) showed spinal infarction below thoracic segment 10. In the clinical course, the patient partially recovered lower limb muscle strength and was able to walk with assistance. To the best of our knowledge, this is the first case in the literature of ASAS with MRI-proven spinal ischemia and the application of rt-PA. Systemic thrombolysis seems to be justifiable in patients with ASAS after the rule-out of aortal dissection and spinal bleeding. PMID:26386968

    Background Catheter-directed thrombolysis (CDT) for deep venous thrombosis (DVT) of the lower extremity has good effect,but whether iliac vein stent placement after thrombolytic therapy is still controversial.The goal of this study was to evaluate the efficacy of stent placement in the iliac vein following CDT in lower extremity DVT.Methods This was a single-center,prospective,randomized controlled clinical trial.After receiving CDT,the major branch of the distal iliac vein was completely patent in 155 patients with lower extremity DVT,and 74 of these patients with iliac vein residual stenosis of >50% were randomly divided into a control group (n=29) and a test group (n=45).In the test group,stents were implanted in the iliac vein,whereas no stents were implanted in the control group.We evaluated the clinical indicators,including patency of the deep vein,C in CEAP classification,Venous Clinical Severity Score (VCSS),and Chronic Venous Insufficiency Questionnaire (CIVIQ) Score.Results All patients had postoperative follow-up visits for a period of 6-24 months.Venography or color ultrasound was conducted in subjects.There was a significant difference between the patency rate at the last follow-up visit (87.5% vs.29.6%) and the 1-year patency rate (86.0% vs.54.8%) between the test and control groups.The change in the C in CEAP classification pre-and post-procedure was significantly different between the test and control groups (1.61±0.21 vs.0.69±0.23).In addition,at the last follow-up visit,VCSS and CIVIQ Score were both significantly different between the test and control groups (7.57±0.27 vs.0.69±0.23; 22.67±3.01 vs.39.34±6.66,respectively).Conclusion The stenting of iliac vein obstruction following CDT in lower extremity DVT may increase the patency of the deep vein,and thus provides better efficacy and quality of life.

  16. Mechanical Recanalization following i.v. Thrombolysis: A Retrospective Analysis regarding Secondary Hemorrhagic Infarctions and Parenchymal Hematomas

    International Nuclear Information System (INIS)

    Introduction. In acute stroke by occlusion of the proximal medial cerebral artery (MCA) or the distal internal carotid artery, intravenous thrombolysis is an established treatment. Another option is mechanical recanalization. It remains unclear if the combination of both methods poses an additional bleeding risk. The aim of this retrospective analysis is to determine the proportion of hemorrhagic infarctions and parenchymal hematomas. Methods. Inclusion criteria were an occlusion of the carotid T or proximal MCA treated with full dose thrombolysis and mechanical recanalization. 31 patients were selected. Devices used were Trevo, Penumbra Aspiration system, Penumbra 3D Retriever, and Revive. The initial control by computed tomography was carried out with a mean delay to intervention of 10.9 hours (SD: 8.5 hours). Results. A slight hemorrhagic infarction (HI1) was observed in 2/31 patients, and a more severe HI2 occurred in two cases. A smaller parenchymal hematoma (PH1) was not seen and a space-occupying PH2 was seen in 2/31 cases. There was no significant difference in the probability of intracranial bleeding after successful (thrombolysis in cerebral infarctions 2b and 3) or unsuccessful recanalization. Conclusion. The proportion of intracranial bleeding using mechanical recanalization following intravenous thrombolysis appears comparable with reports using thrombolysis alone

  19. A comparative study of primary coronary stenting with intravenous thrombolysis for acute myocardial infarction using 99mTc-MIBI SPECT imaging

    International Nuclear Information System (INIS)

    To evaluate and compare the therapeutic effectiveness of primary coronary stenting with that of intravenous thrombolysis for acute myocardial infarction (AMI) using 99mTc-MIBI myocardial SPECT imaging. A total of 42 patients with AMI was undergoing primary coronary stenting (stenting group, 23 patients) or intravenous thrombolysis therapy (thrombolysis groups 19 patients). 99mTc-MIBI myocardium SPECT imaging was performed before and 1 week after stenting or thrombolysis therapy. The left ventricular myocardium of each patient was divided into 20 segments. The semiquantitative score of myocardial 99mTc-MIBI uptake was expressed with a five-point scoring system. The scores of scanning before stenting or intravenous thrombolysis was SBS. The scores of scarring after stenting or intravenous thrombolysis was SAS. Deducting SAS from SBS was SDS. Make a comparison between the SAS. stenting group and fhrombolysis group: SBS was 41.3±9.8 and 39.4±7.9 (t=1.2, P>0.05); SAS was 17.8±6.4 and 27.3±6.7 (t=5.8, P99mTc-MIBI myocardial SPECT imaging has been proved to be an objective parameter for evaluating the therapeutic effectiveness of the stenting and intravenous thrombolysis in treatment of AMI. At the same time;, the results indicate that primary coronary stenting seems to be more effective than intravenous thrombolysis

    We aimed to investigate clinical, demographic and angiographic factors associated with hyperemic coronary blood flow (HCBF) and the relation of HCBF with mortality at 30 days. Our study included 809 consecutive patients with acute ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention (PCI). We divided corrected thrombolysis in myocardial infarction (TIMI) frame count (TFC) values into three tertiles: less than 14, 14-28 and more than 28. Corrected TFC less than 14 was defined as HCBF or TIMI intravenous flow. The primary end-point of the present study was all-cause mortality within 30 days. Among the HCBF group (n = 58), the patients with poor myocardial perfusion demonstrated the highest mortality rate within the 30-day follow-up period (33%). Low TIMI myocardial perfusion grade, history of no smoking, left ventricular ejection fraction (LVEF), and high Killip status and low LVEF were found to be independently associated with 1-month all-cause mortality. The present study showed that HCBF after primary PCI has a high 30-day mortality when associated with impaired reperfusion. PMID:24842315

    Full Text Available Background : Despite the increasing use of recombinant tissue plasminogen activator (rt-PA in acute ischemic stroke, uncertainty persists about the short- and long-term outcome of the thrombolysed patients. Objective : To identify predictors of major neurological improvement at 24 h after intravenous rt-PA administration in patients of acute ischemic stroke and their relationship with outcome at 12 months. Materials and Methods : We analyzed the data of the patients with acute ischemic stroke treated as per the National Institute of Neurological Disorders and Stroke (NINDS criteria with intravenous rt-PA between January 2000 and June 2009 at a tertiary care center in south India. Major neurological improvement was defined by an 8-point improvement in National Institute of Health Stroke Scale (NIHSS score or an NIHSS score of 0 or 1 at 24 h. Good outcome was defined as a 12-month modified Rankin Scale (mRS of 0 to 1. Results : Of the 72 patients with acute ischemic stroke treated with intravenous rt-PA, 23 (32% patients had major neurological improvement at 24 h. Age <60 years (OR 1.9, 95% CI 1.7 to3.2, admission glucose levels <8 mmol/L (OR 3.87, 95% CI 1.9 to 9.2 and mild to moderate baseline stroke severity (NIHSS median score 10+ 6 were associated with major neurological improvement after adjusting for co variables. Major neurological improvement at 24 h was an independent predictor of good outcome (mRS=1 at 12 months (OR 13.9, 95% CI 6.84 to 40.2. Conclusions : Age <60 years, glucose levels <8 mmol/L and mild to moderate stroke severity (NIHSS median score 10±6 was associated with major neurological improvement after intravenous rt-PA. Major neurological improvement at 24 h after the administration of intravenous thrombolysis independently predicted good outcome at 12 months.

  4. Catheter-Directed Thrombolysis for Treatment of Deep Venous Thrombosis in the Upper Extremities

    International Nuclear Information System (INIS)

    Traditional anticoagulant treatment of deep venous thrombosis (DVT) in the upper extremities (UEDVT) is associated with a relatively high incidence of postthrombotic syndrome (PTS). Catheter-directed thrombolysis (CDT) for UEDVT would provide efficient thrombolysis with less subsequent PTS than during traditional anticoagulation. Primary efficacy, complications, and long-term results after CDT are reported in a retrospective cohort (2002-2007) of patients (n = 30) with DVT in the upper extremities. PTS was assessed by a modified Villalta scale. UEDVT was unprovoked in 11 (37%) cases and effort related in 9 (30%) cases. The median duration of symptoms prior to CDT was 7.0 days (range, 1-30); median duration of thrombolysis treatment, 70 h (range, 24-264 h); and the median amount of rt-PA infused during CDT, 52 mg (range, 19-225 mg). Major bleeding was registered in three (9%) patients, and CDT was stopped prematurely in three patients due to local hematoma. No intracerebral bleeding, clinical pulmonary embolism, or deaths occurred during treatment. Grade II (>50%) or III (>90%) lysis was present in 29 patients (97%) at the end of CDT. Bleeding complications increased by each day of delay from the debut of symptoms to the start of treatment (OR, 1.20; 95% CI, 1.01-1.42). At follow-up (n = 29; median, 21 months; range, 5-58 months), 11 (38%) patients had occluded veins, whereas 18 (62%) had patent veins. However, stenosis of varying severity was present in eight of those with a patent vein. No patients had severe PTS, whereas six (21%) experienced mild PTS. In conclusion, our retrospective cohort study of patients with UEDVT showed that treatment restored venous drainage, with a subsequent low frequency of mild PTS at follow-up. Early intervention with CDT prevented bleeding complications.

    Internal carotid artery dissection with tandem internal carotid and middle cerebral artery occlusion may be responsible for large cerebral infarction that carries a general poor prognosis. Recanalization of internal carotid artery (ICA) dissection by stent-assisted thrombolysis has been recently proposed. We report two cases of acute symptomatic ICA dissection with tandem occlusion successfully treated with emergent endovascular stent-assisted thrombolysis using new self-expandable intracranial stents. A 37-year-old woman and a 59-year-old man were admitted in our hospital after acute severe symptoms of right-hemispheric stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 15 and 18, respectively. In both cases, magnetic resonance angiography showed tandem occlusion and angiography confirmed tandem occlusion with ICA dissection. An extensive mismatch region was diagnosed by Perfusion-diffusion MRI of the brain within 3 h after symptoms onset. Treatment was initiated 4 h after symptom onset by implantation of self-expandable intracranial stents into the dissected ICA and administration of intra-arterial recombinant tissue plasminogen activator. Recanalization of the ICA and middle cerebral artery (MCA) was accomplished within 6 h after symptoms onset. In both cases, no periprocedural complication was observed and follow-up CT scan showed only a mild brain infarct in the MCA territory. After, respectively, 12 and 10 months follow-up, patients had a favorable outcome with NIHSS 0 and mRS {<=}1. Endovascular stent-assisted thrombolysis appears to be a promising treatment in tandem occlusion due to ICA dissection. Our work underline the potential use of self-expandable intracranial stents in symptomatic acute ICA dissection. (orig.)

    Full Text Available Abstract Background The widespread use of tissue plasminogen activator (tPA, the only FDA-approved acute stroke treatment, remains limited by its narrow therapeutic time window and related risks of brain hemorrhage. Normobaric oxygen therapy (NBO may be a useful physiological strategy that slows down the process of cerebral infarction, thus potentially allowing for delayed or more effective thrombolysis. In this study we investigated the effects of NBO started simultaneously with intravenous tPA, in spontaneously hypertensive rats subjected to embolic middle cerebral artery (MCA stroke. After homologous clot injection, animals were randomized into different treatment groups: saline injected at 1 hour; tPA at 1 hour; saline at 1 hour plus NBO; tPA at 1 hour plus NBO. NBO was maintained for 3 hours. Infarct volume, brain swelling and hemorrhagic transformation were quantified at 24 hours. Outcome assessments were blinded to therapy. Results Upon clot injection, cerebral perfusion in the MCA territory dropped below 20% of pre-ischemic baselines. Both tPA-treated groups showed effective thrombolysis (perfusion restored to nearly 100% and smaller infarct volumes (379 ± 57 mm3 saline controls; 309 ± 58 mm3 NBO; 201 ± 78 mm3 tPA; 138 ± 30 mm3 tPA plus NBO, showing that tPA-induced reperfusion salvages ischemic tissue and that NBO does not significantly alter this neuroprotective effect. NBO had no significant effect on hemorrhagic conversion, brain swelling, or mortality. Conclusion NBO can be safely co-administered with tPA. The efficacy of tPA thrombolysis is not affected and there is no induction of brain hemorrhage or edema. These experimental results require clinical confirmation.

    Here we present a patient after implantation of a left ventricular assist device (HeartWare) for destination therapy complicated by recurrent thrombosis of the device. At 14 months after implantation, the patient presented with a pump thrombosis after an INR incompliance period. A surgical pump exchange was performed and the patient recovered uneventfully. Five months later a pump thrombosis occurred again, and the patient refused surgery. Systemic thrombolysis was carried out this time. Three and 6 months later the same clinical picture was presented again, and repeat thrombolysis was performed successfully. The patient was discharged and has remained stable since, without any symptoms of thrombosis of the device. PMID:26336463

  8. NeuroSPECT assessment of ischemic penumbra in acute brain infarct: control of intra-arterial thrombolysis

    International Nuclear Information System (INIS)

    Introduction: Brain infarct is the most common cause of incapacity in adults, the second cause of dementia and the 2nd or 3rd cause of death. Acute brain infarct is a medical emergency potentially reversible if treated with thrombolysis in the first hours of evolution. Thrombolysis is now an approved and efficacious method of treatment for acute ischemic stroke. During the first 3 hours of evolution, intravenous administration of plasminogen activator (tPA) can be performed. The window of time of treatment is expanded to 6 hours with the intra-arterial super selective route for thrombolysis. Aim: The aim of this study was to define levels of reversible ischemia (penumbra) demonstrated by statistically evaluated HMPAO Tc99m NeuroSPECT performed before and after intra-arterial thrombolysis in the treatment of acute infarct. Materials and Methods: 21 patients were treated during the first 6 hours of evolution of an acute ischemic stroke with the following protocol. 1) Admission, and complete neurological evaluation. 2) Brain CT scan to rule hemorrhage or established infarct. 3) I.V injection of 1100MBq Tc99m HMPAO (Ceretec tm) 4) Conventional cerebral angiography and intra-arterial thrombolysis and/or angioplasty/stenting if necessary. 5) NeuroSPECT assessment of ischemic penumbra. 6) Control at 24 hrs with NeuroSPECT. NeuroSPECT image acquisition is performed immediately following arterial thrombolysis with a dual Head Camera, SHR collimators and conventional protocol. Image processing was performed using the Segami Software, as previously reported in Alasbimn Journal2 (7): April 2000. http://www.alasbimnjournal.cl. The analysis consists of 1) Tallairach brain volume normalization. 2) Voxel by voxel comparison of the individual brain cortex uptake normalized to the maximum in the cortex with a normal database of 24 age-matched controls. Results: The results are expressed in standard deviations (S.D.) below the normal mean. Normal mean is 72% + 6. Only voxels between

    Postoperative inferior vena cava (IVC) thrombosis is a potentially lethal complication in a liver transplant recipient. We report the case of a 57-year-old liver transplant recipient, who developed acute, postoperative, markedly symptomatic complete IVC, ilial-femoral-caval, and left renal vein thrombosis. After treatment with power-pulse tissue plasminogen activator thrombolysis, thrombectomy, and stent placement, the IVC and iliac veins were successfully recanalized. At 2.5-year imaging and laboratory follow-up, the IVC, iliac, and renal veins remained patent and graft function was preserved.

    Prehospital thrombolysis for acute ST-elevation myocardial infarction (STEMI) has been shown to improve recovery from myocardial function. We describe prehospital thrombolytic treatment in two patients suffering from STEMI complicated by ventricular fibrillation (VF) on a passenger ship. The importance of a functioning Emergency Medical Service (EMS) system providing guidance for paramedical personnel is discussed briefly. Both our patients survived and returned back to normal life. It is concluded that EMS physician guided prehospital thrombolytic treatment may offer an important therapeutic option for nurses or paramedics in locations out of reach of ordinary EMS services.

    A blood clot or thrombus triggers the onset of most vascular diseases, like stroke or heart attack. Thrombolysis is the only treatment that can restore blood flow rapidly and easily. Unfortunately, the standard thrombolytic, tissue plasminogen activator (tPA), has proven inadequate and is being replaced by invasive endovascular procedures, which are time consuming and limited in their availability in relation to the scope of the problem. Historically, when tPA clinical trials began, it was not recognized sufficiently that without the other natural plasminogen activator, prourokinase (proUK), thrombolysis by tPA was seriously compromised. The reason is that the 2 activators have complementary mechanisms of action in fibrinolysis, making their combination a requirement for optimal efficacy and synergy. Biological fibrinolysis also uses both activators, explaining why such low endogenous concentrations are sufficient. A low-dose sequential combination of tPA and proUK was tested in acute myocardial infarction, where it was exceptionally effective and safe. Because native proUK at pharmacological doses was vulnerable to spontaneous conversion to urokinase, jeopardizing safety, a site-directed mutant was developed that improved proUK's plasma stability fivefold without interfering with its mode of action.

    Coronary arteries isolated from cadavers autopsied within 7 hours after death were perfused with canine arterial blood, and the processes of thrombus formation at the segments stenosed with atheroma and the thrombolytic effects of urokinase were investigated by angioscopy. Ten minutes of blood perfusion caused thin mural thrombi localized at the stenotic or nonstenotic segments. During 30 minutes of blood perfusion, the thin mural thrombi of the outlet or inlet of the segment grew into a doughnut-shaped thrombus. Also, the thin mural thrombi in the stenotic segment grew into a streamer-like thrombus and drifted downstream. These thrombi grew in size with increasing perfusion time and finally obstructed the stenotic segment. Globular thrombi close to the outlet also were formed in a few preparations. Unlike the thrombi at the stenotic segment, the mural thrombi in the nonstenotic segments did not grow into massive thrombi. The thrombi were reduced in size within 10 minutes of perfusion with 320 U/ml or more of urokinase. During thrombolysis, sandstorm-like dispersion of the blood cells occurred, small fragments detached from the mother thrombus and flew downstream, or the fibrin core of the thrombus was exposed. The results indicate the usefulness of angioscopy for the dynamic and serial investigation of thrombosis and thrombolysis. PMID:3766368

    The purpose of the study was to review the current status of intraarterial (IA) thrombolysis in Korea by conducting a retrospective analysis of the data from multiple domestic centers. The radiologists at each participating institution were asked to fill out case report forms on all patients who had undergone IA recanalization due to acute anterior circulation ischemia. These forms included clinical, imaging and procedure-related information. A central reader analyzed the CT/MR and angiographic results. The rates of successful recanalization, hemorrhagic transformation and functional outcome were obtained. The univariate analyses were performed together with the multivariate analysis. We analyzed the data from 163 patients, and they had been treated at seven institutes. The initial imaging modalities were CT for 46 patients (28%), MR for 63 (39%), and both for 54 (33%). Various mechanical treatment methods were applied together in 50% of the patients. Radiologically significant hemorrhage was noted in 20/155 patients (13%). We found various factors that influenced the recanalization rate and the occurrence of significant hemorrhagic transformations. The favorable outcome rate, reported as modified Rankin Scale {<=}2, was 40%, and the mortality rate was 11%. The factors that predicted a poor functional outcome were old age (p = 0.01), initially severe neurological symptoms (p < 0.0001), MR findings of a wide distribution of lesions (p = 0.001), involvement of the basal ganglia (p = 0.01), performance of procedures after working hours (p 0.01), failure of recanalization (p 0.003), contrast extravasation after the procedure (p = 0.007) and significant hemorrhagic transformation (p = 0.002). The subsequent multivariate analysis failed to show any statistically significant variable. There was a trend toward increased dependency on MR imaging during the initial evaluation and increased usage of combined pharmacologic/mechanical thrombolysis. The imaging and clinical

    International Nuclear Information System (INIS)

    Purpose: To evaluate treatment decision-making based on susceptibility-weighted imaging (SWI) in patients with hemorrhage after thrombolysis. Materials and methods: One hundred and forty-six patients without intracranial hemorrhage on CT after receiving recombinant tissue plasminogen activator (rt-PA) were allocated to two groups: antiplatelets (n = 72), who received antiplatelet therapy 24 h after rt-PA for 10 days; and non-antiplatelets (n = 74), who received no antiplatelet therapy. Twenty-two patients with SWI-detected microbleeds (MBs) or hemorrhagic transformation (HT) in the antiplatelets group (Group A) and 28 with MB or HT in the non-antiplatelets group (Group B) were included in this study. Results: Sixteen patients had MB and six HT in Group A; 18 had MB, six HT, and four parenchymal hemorrhage (PH) in Group B. National Institutes of Health Stroke Scale (NIHSS) scores at 7 and 14 days and the Modified Rankin Scale (mRS) at 90 days post-rt-PA were significantly lower in Group B than in Group A, duration of hospitalization was significantly shorter, and the favorable outcome rate was higher at 90 days (P < 0.05). There were no other significant differences. SWI evaluation at 14 days revealed eight patients with MB, 11 HT, and three PH in Group A; in Group B, 16 had MB, five HT, and one PH, with resolution of hemorrhage in six patients. Conclusions: Treatment decision-making based on SWI in acute stroke after thrombolysis was validated by the significantly reduced NIHSS score after 7/14 days, improved outcome, and reduced mRS in hemorrhage patients without antiplatelet therapy.

  19. Distance to thrombus on MR angiography predicts outcome of middle cerebral artery occlusion treated with IV thrombolysis

    International Nuclear Information System (INIS)

    The distance to thrombus (DT) on CT angiography was recently proposed as a predictor of outcome in patients treated by intravenous thrombolysis (IVT) for stroke due to occlusion of the middle cerebral artery (MCA). The purpose of the present study was to validate its inter-rater reliability and its prognostic value on contrast-enhanced magnetic resonance angiography (CE-MRA). Furthermore, we investigated the relation between DT and FLAIR-vascular hyperintensities (FVH) as a surrogate of collateral circulation and hypoperfusion. Patients with acute MCA occlusions treated by IVT and diagnosed with magnetic resonance imaging (MRI) were included. Two readers measured DT. FVH and acute DWI lesion volumes were quantified. Clinical status was determined using the initial NIH stroke scale (NIHSS) and 90-day modified Rankin Scale (90d mRS). Sixty-one patients showed a lesion on diffusion-weighted magnetic resonance images and an occlusion of the MCA on CE-MRA. We found significant inverse correlations between DT and NIHSS scores at admission (ρ = -0.29; P = 0.02), DT and mRS at 90 days (ρ = -0.29; P = 0.04), and between DT and FVH (ρ = -0.32; P = 0.01). For a DT <22 mm, the likelihood of an unfavorable outcome (90d mRS 3-6 or NIHSS score improvement of ≤10 points at discharge) was >50 %. Initial DWI lesion volumes showed no correlation with the outcome. Excellent inter-rater agreement for DT was observed (Cronbach's α = 0.98; P < 0.001). DT on CE-MRA is reliably measurable, correlates inversely with FLAIR-vascular hyperintensities, and predicts outcome in patients with acute MCA occlusion treated with IVT. (orig.)

  2. Catheter-Directed Thrombolysis of Acute Deep Vein Thrombosis in the Lower Extremity of a Child with Interrupted Inferior Vena Cava

    International Nuclear Information System (INIS)

    We present the case of a 14-year-old girl who developed acute deep vein thrombosis (DVT) in her right lower extremity. Laboratory testing revealed protein S deficiency, and the patient's father also had this abnormality with a history of lower extremity DVT. Manual thromboaspiration followed by catheter-directed thrombolysis resulted in total clearance of all thrombi. Computed tomography and later venography revealed an interrupted inferior vena cava. Catheter-directed thrombolysis is an established treatment for adults with acute DVT. To the best of our knowledge, this report is the first to describe catheter-directed thrombolysis in a pediatric patient with lower extremity DVT. Our results suggest that catheter-directed thrombolysis is safe and effective for use in selected older children and adolescents with acute DVT in the lower extremity

    2013-04-01

    Full Text Available In the Netherlands in 2010, 11% of patients with ischemic stroke received intravenous thrombolysis (IVT, varying from 4 to 26% between hospitals. The aim of this study was to investigate variation in clinical practice and organization of IVT in relationship to performance and outcome. In all 84 Dutch hospitals performing IVT, a stroke neurologist was approached using a web-based survey. The response rate was 82%. The study showed considerable variation. For example, door-to-needle time ranged from 25 to 80 min. High blood pressure was actively lowered before performing IVT by 57% of neurologists, while 35% chose to wait. 28% started IVT without knowledge of laboratory results. Better follow-up data are needed to see whether this variation results in differences in outcome.

    The authors report the case of a 67 year old man with a previous history of aortobifemoral arterial graft who had unstable angina after carotid endarterectomy. Coronary angiography by the right brachial artery was complicated by a cerebrovascular accident with a reactive coma, convulsions and respiratory problems. Selective angiography of the right vertebral artery showed an image of occlusive thrombosis of the basilar artery. In view of the clinical state and angiographic appearances, the authors decided on immediate intra-arterial thrombolysis with Urokinase which dissolved the clot and reestablished flow in the basilar artery, the cerebellar and posterior cerebral arteries. The outcome was favourable with immediate and good recovery of consciousness and hospital discharge on the sixth day without neurological or radiological sequellae. Cerebrovascular accident is a rare and potentially serious complication of left heart catheterisation which requires immediate cerebral angiography to determine the mechanism and propose an appropriate therapeutic approach.

    Intravenous thrombolysis (IVT) as treatment in acute ischaemic strokes may be insufficient to achieve recanalisation in certain patients. Predicting probability of non-recanalisation after IVT may have the potential to influence patient selection to more aggressive management strategies. We aimed at deriving and internally validating a predictive score for post-thrombolytic non-recanalisation, using clinical and radiological variables. In thrombolysis registries from four Swiss academic stroke centres (Lausanne, Bern, Basel and Geneva), patients were selected with large arterial occlusion on acute imaging and with repeated arterial assessment at 24 hours. Based on a logistic regression analysis, an integer-based score for each covariate of the fitted multivariate model was generated. Performance of integer-based predictive model was assessed by bootstrapping available data and cross validation (delete-d method). In 599 thrombolysed strokes, five variables were identified as independent predictors of absence of recanalisation: Acute glucose > 7 mmol/l (A), significant extracranial vessel STenosis (ST), decreased Range of visual fields (R), large Arterial occlusion (A) and decreased Level of consciousness (L). All variables were weighted 1, except for (L) which obtained 2 points based on β-coefficients on the logistic scale. ASTRAL-R scores 0, 3 and 6 corresponded to non-recanalisation probabilities of 18, 44 and 74 % respectively. Predictive ability showed AUC of 0.66 (95 %CI, 0.61-0.70) when using bootstrap and 0.66 (0.63-0.68) when using delete-d cross validation. In conclusion, the 5-item ASTRAL-R score moderately predicts non-recanalisation at 24 hours in thrombolysed ischaemic strokes. If its performance can be confirmed by external validation and its clinical usefulness can be proven, the score may influence patient selection for more aggressive revascularisation strategies in routine clinical practice.

    A patient was admitted because of severe abdominal pain, anorexia, and intestinal bleeding. Contrast-enhanced multidetector computed tomography demonstrated acute portal and superior mesenteric vein thrombosis (PSMVT). The patient was treated percutaneously with transjugular intrahepatic portosystemic shunt (TIPS), mechanical aspiration thrombectomy, and direct thrombolysis, and 1 week after the procedure, complete patency of the portal and superior mesenteric veins was demonstrated. TIPS, mechanical aspiration thrombectomy, and direct thrombolysis together are promising endovascular techniques for the treatment of symptomatic acute PSMVT

    International Nuclear Information System (INIS)

    Arterial rupture subsequent to angioplasty occurs in about 5% of cases. Thrombolysis with re-establishment of flow without resolving underlying anatomic defects such as hepatic arterial stenosis leads to re-thrombosis. We present a case of arterial anastomotic rupture after thrombolysis and angioplasty of an underlying anastomotic hepatic arterial stenosis. Both the underlying anatomic defect and the rupture were resolved successfully with placement of a stent-graft, with a resultant patent artery for 1 year after the procedure.

  11. Comparative Efficacy of Pulse-Spray Thrombolysis and Angioplasty Versus Surgical Salvage Procedures for Treatment of Recurrent Occlusion of PTFE Dialysis Access Grafts

    International Nuclear Information System (INIS)

    Purpose: To compare the efficacy of surgery versus pulse-spray thrombolysis and angioplasty in patients with recurrent thrombosis of polytetrafluoroethylene (PTFE) dialysis access grafts. Methods: We analyzed 96 consecutive interventions for thrombosed PTFE dialysis access grafts in 18 patients. Primary patency after thrombolysis and angioplasty (n= 25) was compared with primary patency following thrombectomy alone (n= 50) or thrombectomy followed by graft revision (n= 21) using life-table analysis. A Cox proportional hazards model that accounted for graft age and number of previous interventions was used to generate the relative risk for recurrent occlusion following therapy. Results: Life-table analysis showed that patency after thrombolysis and angioplasty was greater than that following thrombectomy alone (p= 0.02). After accounting for the age of the graft and the number of previous interventions (average six per patient), the relative risk for recurrent occlusion [3.0; 95% confidence intervals (CI): 1.5, 6.4] was greater for thrombectomy alone than for thrombolysis/angioplasty [0.6; CI = 0.3, 1.3]. The relative risks of repeat occlusion following thrombolysis/angioplasty [0.6; CI = 0.3, 1.3] and thrombectomy/surgical revision [1.0; CI = 0.5, 1.7] were similar. Conclusion: Outcome data from our retrospective study on recurrent thrombosis of PTFE dialysis access grafts suggest that thrombolysis/angioplasty is superior to thrombectomy alone, and equivalent to thrombectomy/surgical revision

    2016-08-01

    Full Text Available Background: Thrombolysis is the only approved therapy for acute stroke. However, life-threatening complications such as intracerebral hemorrhage (ICH can develop after intravenous administration of tissue plasminogen activator (tPA. Both infection and thrombolysis during cerebral ischemia disrupt the blood-brain barrier (BBB. tPA can induce matrix metalloproteinase-9 (MMP-9, which is known to be involved in BBB disruption. However, it has still not been investigated whether preexisting influenza virus infection during thrombolysis after acute stroke affects systemic levels of MMP-9 and its inhibitor TIMP-1 and whether increased systemic MMP-9 levels affect ICH. This study aimed to investigate the influence of influenza virus infection on plasma levels of MMP-9 and TIMP-1 after thrombolysis in acute stroke, and to determine whether the infection correlates with intracerebral bleeding. Methods: C57BL/6 mice were infected by administering 1 × 105 plaque-forming units of human influenza (H1N1 virus intranasally. After 3 days of infection the middle cerebral artery was occluded for 45 min and then reperfused. Intravenous tPA (10 mg/kg treatment was started 10 min after stroke onset. Twenty-four hours after stroke onset, mice were deeply anesthetized with ketamine, venous blood was drawn from the caval vein and centrifuged at 2,000 rpm, and the supernatant was collected and frozen at -80°C. Plasma levels of MMP-9 and TIMP-1 were quantified by using ELISA. Results: After stroke, plasma MMP-9 was significantly increased in mice with a concomitant influenza infection that were treated with tPA (9.99 ± 0.62 ng/ml, n = 7 as compared to noninfected control mice that were treated with tPA (4.74 ± 0.48 ng/ml, n = 8. Moreover, plasma levels of TIMP-1, an inhibitor of MMP-9, were also significantly increased in mice treated with tPA after concomitant infection and stroke (42.17 ± 7.02 ng/ml, n = 7 as compared to noninfected control mice that were treated

    Purpose: A rare but described risk factor for deep venous thrombosis (DVT), predominately in the young, is congenital agenesis or atresia of the inferior vena cava (IVC). The optimal management for DVT in this subset of patients is unknown. We evaluated the efficacy of pharmacomechanical catheter-directed thrombolysis (PCDT) followed by systemic anticoagulation in the treatment of acute lower-extremity DVT in the setting of congenital IVC agenesis or atresia. Materials and Methods: Between November of 2005 and May of 2010, six patients (three women [average age 21 years]) were referred to our department with acute lower-extremity DVT and subsequently found to have IVC agenesis or atresia on magnetic resonance imaging. A standardized technique for PCDT (the Angiojet Rheolytic Thrombectomy System followed by the EKOS Microsonic Accelerated Thrombolysis System) was used for all subjects. Successful thrombolysis was followed by systemic heparinization with transition to Coumadin or low molecular-weight heparin and compression stockings. Subjects were followed-up at 1, 3, and then every 6 months after the procedure with clinical assessment and bilateral lower-extremity venous ultrasound. Results: All PCDT procedures were technically successful. No venous stenting or angioplasty was performed. The average thrombolysis time was 28.6 h (range 12-72). Two patients experienced heparin-induced thrombocytopenia, and one patient developed a self-limited knee hemarthrosis, No patients were lost to follow-up. The average length of follow-up was 25.8 {+-} 20.2 months (range 3.8-54.8). No incidence of recurrent DVT was identified. There were no manifestations of postthrombotic syndrome. Conclusions: PCDT followed by systemic anticoagulation and the use of compression stockings appears to be safe and effective in relatively long-term follow-up treatment of patients who present with acute DVT and IVC agenesis or atresia.

Subjects were followed-up at 1, 3, and then every 6 months after the procedure with clinical assessment and bilateral lower-extremity venous ultrasound. Results: All PCDT procedures were technically successful. No venous stenting or angioplasty was performed. The average thrombolysis time was 28.6 h (range 12–72). Two patients experienced heparin-induced thrombocytopenia, and one patient developed a self-limited knee hemarthrosis, No patients were lost to follow-up. The average length of follow-up was 25.8 ± 20.2 months (range 3.8–54.8). No incidence of recurrent DVT was identified. There were no manifestations of postthrombotic syndrome. Conclusions: PCDT followed by systemic anticoagulation and the use of compression stockings appears to be safe and effective in relatively long-term follow-up treatment of patients who present with acute DVT and IVC agenesis or atresia.

  16. Thrombolysis by intravenous tissue plasminogen activator (t-PA). Current status and future direction

    International Nuclear Information System (INIS)

    In Japan, the intravenous tissue plasminogen activator (t-PA) Alteplase (0.6 mg/kg) administration of the within 3 h of the onset of acute ischemic stroke was approved for therapeutic use in the year 2006. t-PA induces thrombolysis in patients with acute ischemic stroke, and this method has gradually gained recognition among physicians and the general population. However, the number of patients who were treated using Alteplase is low (4,000-5,000 patients/year), and this figure accounts for only 2-3% of the annual number of cases of ischemic stroke. There is little doubt that Alteplase treatment is a potentially effective modality for some patients with acute ischemic stroke. The post-marketing surveillance of 4,749 Japanese patients treated using Alteplase showed that 33% of the patients had modified Rankin scale (mRS) scores of 0-1, 17% of patients died and 4.5% presented with symptomatic intracerebral hemorrhage (ICH); these results were comparable to those from other countries. The expansion of the therapeutic time window has been a matter of concern. The investigators of the European Cooperative Acute Stroke Study (ECASS) have reported that there was significant improvement in the clinical outcomes of patients with acute ischemie stroke when Alteplase was administered 3-4.5 h after the onset of the symptoms. Mismatches in perfusion- and diffusion-weighted (DW) magnetic resonance imaging (MRI) images have been used for selecting patients 3 h after the onset of symptoms, and the findings from MRI, dwimages (DWI) and MR angiography are practical predictors of t-PA therapy within 3 h of onset. The Middle Cerebral Artery Embolism Local Fibrinolytic Intervention Trial (MELT) Japan study showed that local intra-arterial fibrinolysis is effective in patients with embolic MCA occlusion within 6 h of the onset of symptoms. Combining the initiation of intravenous t-PA administration with further intra-arterial fibrinolysis or mechanical thrombolectomy may improve the

    The aim of this study was to evaluate the impact of pretreatment quality of collaterals, involving velocity and extent of collateral filling, on recanalization after intravenous thrombolysis (IVT). A retrospective analysis was performed of 66 patients with acute middle cerebral artery (MCA) M1 segment occlusion who underwent MR perfusion (MRP) imaging before IVT. The velocity of collateral filling was defined as arrival time delay (ATD) of contrast bolus to Sylvian fissure between the normal and the affected hemisphere. The extent of collateral filling was assessed according to the Alberta Stroke Program Early CT (ASPECT) score on temporally fused maximum intensity projections (tMIP). Arterial occlusive lesion (AOL) score was used to assess the degree of arterial recanalization. ATD (OR = 0.775, 95% CI = 0.626-0.960, p = 0.020), but not tMIP-ASPECT score (OR = 1.073, 95% CI = 0.820-1.405, p = 0.607), was independently associated with recanalization (AOL score of 2 and 3) at 24 hours after IVT. When recanalization was achieved, hemorrhagic transformation (HT) occurred more frequently in patients with slow collaterals (ATD ≥ 2.3 seconds) than those with rapid collaterals (ATD stroke.

    Full Text Available Systemic thrombolysis using recombinant tissue plasminogen activator is the most effective and safe therapy option for ischemic stroke (IS in the first 4.5 hours after onset of the disease. The safety and efficiency (or inefficiency of perfusion therapy in patients with IS may be affected by a multitude of factors associated with the time of the therapy, patient age, the presence and size of a brain region with potentially reversible changes, the location of a cerebral lesion region, the specific features of systemic and local hemodynamics, and the degree of blood-brain barrier impairment. The hemorrhagic transformation of a brain lesion focus in IS is a serious complication of thrombolytic therapy (TT. The analysis and detection of predictors for hemorrhagic complications, TT in terms of the clinical and pathogenetic features of the disease, the location of a lesion focus and the degree of early neuroimaging signs, and data of additional studies will contribute to the safer and more effectiveuse of this treatment in patients with IS.

    Full Text Available It was suggested that intravenous thrombolysis (IT leads to larger extent recanalization in cardioembolic stroke. In this work we assess if this has beneficial clinical traduction. METHOD: We evaluated 177 patients undergoing IT, which were categorized into cardioembolic (CE and non-cardioembolic (NCE. National Institutes of Health Stroke Scale (NIHSS and modified Rankin scale were compared. RESULTS: The mean age was 67.4±12.01 and 53.8% were male. The mean NIHSS was: 14 (admission, 9 (24 h and 6 (discharge, similar in subgroups. The difference between NIHSS at admission and 24 hours was 4.17±4.92 (CE: 4.08±4.71; NCE: 4.27±5.17, p=0.900 and at admission and discharge there was an average difference of 6.74±5.58 (CE: 6.97±5.68; NCE: 6.49±5.49, p=0.622. The mRS at discharge and 3 months was not significantly different by subtype, although individuals whose event was NCE are more independent at 3 months. CONCLUSION: Ours findings argue against a specific paper of IT in CE. It can result from heterogeneity of NCE group.

  2. Mobile CT. Technical aspects of prehospital stroke imaging before intravenous thrombolysis

    International Nuclear Information System (INIS)

    To reduce the time from symptom onset to treatment with tissue plasminogen activator (tPA) in ischemic stroke, an ambulance was equipped with a CT scanner. We analyzed process and image quality of CT scanning during the pilot study regarding image quality and safety issues. The pilot study of a stroke emergency mobile unit (STEMO) ran over a period of 12 weeks on 5 weekdays from 7a. m. to 6:30 p. m. A teleradiological service for the justifying indication and reporting was established. The radiographer was responsible for the performance of the CT scan on the ambulance. 64 cranial CT scans and 1 intracranial CT angiography were performed. We compared times from ambulance alarm to treatment decision (time of last brain scan) with a cohort of 50 consecutive tPA treatments before implementation of STEMO. 62 (95 %) of the 65 scans performed had sufficient quality for reading. Technical quality was not optimal in 45 cases (69 %) mainly caused by suboptimal positioning of patient or eye lense protection. Motion artefacts were observed in 8 exams (12 %). No safety issues occurred for team or patients. 23 patients were treated with thrombolysis. Time from alarm to last CT scan was 18 minutes shorter than in the tPA cohort before STEMO implementation. A teleradiological support for primary stroke imaging by CT on-site is feasible, quality-wise of diagnostic value and has not raised safety issues. (orig.)

The semi-quantitative Alberta Stroke Program Early CT Score (ASPECTS is found to have prognostic value in early stroke. This study assesses factors associated with the presence of EIC and the relation between EIC and clinical outcome.Materials and methods: CT scans from 61 consecutive patients receiving thrombolytic therapy were reviewed by 3 experienced stroke neurologists, assessing EIC (ASPECTS and vascular signs (hyperdense middle cerebral artery stem and/or branches. Short-term outcome was assessed with the National Institute of Health Stroke Scale at 24 hours and long-term outcome with the modified Rankin Scale score after 3 months.Results: The prevalence of EIC was 54% and the agreement between assessors was good (kappa 0.52–0.67. EIC was independently associated with younger age and absence of diabetes mellitus. Neither EIC nor vascular signs were associated with 3-months outcome.Conclusions: ASPECTS is as simple, systematic approach to assessing EIC, and the interobserver agreement is good. Patient age and diabetes mellitus influence the presence of EIC.Keywords: acute stroke, computed tomography, ischemia, thrombolysis

    Full Text Available More than 70% of cardiac arrest cases are caused by acute myocardial infarction (AMI or pulmonary embolism (PE. Although thrombolytic therapy is a recognised therapy for both AMI and PE, its indiscriminate use is not routinely recommended during cardiopulmonary resuscitation (CPR. We present a case describing the successful use of double dose thrombolysis during cardiac arrest caused by pulmonary embolism. Notwithstanding the relative lack of high-level evidence, this case suggests a scenario in which recombinant tissue Plasminogen Activator (rtPA may be beneficial in cardiac arrest. In addition to the strong clinical suspicion of pulmonary embolism as the causative agent of the patient’s cardiac arrest, the extremely low end-tidal CO2 suggested a massive PE. The absence of dilatation of the right heart on subxiphoid ultrasound argued against the diagnosis of PE, but not conclusively so. In the context of the circulatory collapse induced by cardiac arrest, this aspect was relegated in terms of importance. The second dose of rtPA utilised in this case resulted in return of spontaneous circulation (ROSC and did not result in haemorrhage or an adverse effect.

  7. Hypothenar hammer syndrome: Long-term follow-up of selective thrombolysis by 3.0-T MR angiography

    International Nuclear Information System (INIS)

    Objective: To assess the long-term outcome of selective thrombolysis in patients with hypothenar hammer syndrome by 3.0-T magnetic resonance (MR) angiography. Materials and methods: Seven patients (6 men, 1 woman; mean age, 58.6 ± 14.4 years) were investigated. Long-term follow-up examinations (9-11 years post-interventional) were based on 3.0-T MR angiography. Pre- versus post-thrombolysis images and post-thrombolysis versus long-term follow-up images were compared with respect to arterial diameter. Additionally, changes in patients' symptoms were assessed. Results: The long-term follow-up examination showed worse contrast filling of the ulnar digits compared to the immediately post-interventional angiographic images only in one patient (14.3%), whereas worse contrast filling of the deep palmar arch or the ulnar artery was registered in three patients (42.9%). Three of seven patients (42.9%) reported worse symptoms, two patients (28.6%) stable symptoms at the long-term follow-up MR angiography. In two patients (28.6%) the change of symptoms could not be observed due to missing post-interventional clinical data. Conclusions: At the long-term follow-up, clinically, mild progression was found rather often, whereas with respect to imaging findings progression at the ulnar digits was rare. We assume that collateral vessels might play a major role in the post-interventional follow-up. In many instances the patients' symptoms are not in line with the angiographic findings.

  9. Transcatheter Thrombolysis with High-Dose Bolus Tissue Plasminogen Activator in Iatrogenic Arterial Occlusion after Femoral Arterial Catheterization

    International Nuclear Information System (INIS)

    Purpose: To assess the efficacy of percutaneous local thrombolysis with high-dose bolus recombinant tissue plasminogen activator (rt-PA) in patients with acute limb ischemia due to arterial thrombosis after cardiac catheterization.Methods: We treated eight patients (7 men; mean age 56 years) with thrombotic occlusion of both the common femoral artery (CFA) and external iliac artery (EIA) in six patients and of the CFA only in two patients. Two 5 mg boluses of rt-PA were injected into the proximal clot through a 5 Fr end-hole catheter and subsequently two additional boluses of 5 mg rt-PA were given through a catheter with multiple side-holes. In case of a significant amount of residual thrombus, a continuous infusion of 2.5 mg/hr of rt-PA was started.Results: Successful lysis was achieved in all patients. The mean duration of lysis was 2 hr 41 min. The mean total amount of rt-PA delivered was 23.16 mg. In four patients unmasked flow-limited dissections confined to the CFA were managed by prolonged balloon dilatation, while in the remaining four patients with extension of the dissection to the external iliac artery one or two Easy Wallstents were implanted. There was prompt relief of lower limb ischemic symptoms and signs in all patients. Two groin hematomas were conservatively treated.Clinical and color Doppler flow imaging follow-up with a mean duration of 15 months, showed no reappearance of ischemic symptoms or development of restenosis in any of the patients. One patient died 6 months after thrombolysis.Conclusions: Transcatheter thrombolysis with high-dose bolus rt-PA is a safe and effective treatment inpatients with iatrogenic arterial occlusion after femoral catheterization. Underlying dissections should be treated by prolonged balloon dilatation but stent implantation is often required

    Centralization of intravenous thrombolysis (IVT) for acute ischemic stroke in high-volume centers is believed to improve the door-to-needle times (DNT), but limited data support this assumption. We examined the association between DNT and IVT volume in a large Dutch province. We identified consecutive patients treated with IVT between January 2009 and 2013. Based on annualized IVT volume, hospitals were categorized as low-volume (≤24), medium-volume (25–49) or high-volume (≥50). In logistic r...

  11. Percutaneous aspiration thrombectomy for the treatment of acute lower extremity deep vein thrombosis: is thrombolysis needed?

    International Nuclear Information System (INIS)

    Aim: To assess the technical feasibility and initial success of aspiration thrombectomy as a potential alternative to lytic therapy in initial endovascular management of acute lower extremity deep vein thrombosis (DVT). Materials and Methods: From July 2004 to October 2007, a retrospective analysis of 27 patients (male:female 5:22; mean age 59 years) with acute iliofemoral or femoropopliteal DVT of less than 2 weeks was performed. All patients underwent sonography of the lower extremities, and 13 patients underwent computed tomography (CT) venography. All patients received an inferior vena cava (IVC) filter and were initially treated with aspiration thrombectomy using the pullback technique with or without basket thrombus fragmentation. If persistent stenotic portions (>50% luminal narrowing) were noted, balloon angioplasty or stent placement was performed. Successful recanalization was defined as successful restoration of antegrade flow in the treated vein with elimination of any underlying obstructive lesion. Results: The mean procedure time was 65 min (range 40-100 min). Successful initial recanalization was achieved in 24 patients (88.9%) without complications. Urokinase was required for three patients (11.1%) due to a hard thrombus remaining in the iliac vein. Of the 27 patients, 23 had residual venous stenosis in the common iliac vein or external iliac vein. Therefore, balloon angioplasty (n = 23) and stent placement (n = 22) was performed. The remaining four patients were treated using only aspiration thrombectomy without angioplasty or stent placement. Conclusion: Aspiration thrombectomy without catheter-directed thrombolysis is a safe and effective treatment for acute DVT of the lower extremities, and minimizes the risk of haemorrhagic complications.

  12. The role of connexin43 in hemorrhagic transformation after thrombolysis in vivo and in vitro.

    Thrombolysis with recombinant tissue plasminogen activator (rtPA) is the most effective drug treatment for acute ischemic stroke within 4.5h after symptom onset. However, the use of rtPA may increase the risk of hemorrhagic transformation (HT), particularly when it is administered after the first 4.5h. However, no effective treatments are available to reduce the HT risk. Disruption of the blood-brain barrier (BBB) is central to the genesis of HT. Connexin43 (Cx43)-mediated gap junction intercellular communication (GJIC) has been demonstrated to regulate the integrity of the BBB in ischemia. We investigated the effect of Cx43 on BBB permeability during rtPA-induced HT. Spontaneously hypertensive rats (SHRs) underwent a 1.5-h middle cerebral artery occlusion and were treated with rtPA at 4.5h. The rats were sacrificed at 24h, and their brains were evaluated for BBB permeability and the expression of tight junction (TJ) proteins and Cx43. We examined whether the effects were Cx43 dependent using multiple Cx43 inhibitors. Phosphorylated Cx43 (p-Cx43) but not total Cx43 protein expression was increased after rtPA treatment. Delayed rtPA administration induced significant HT and BBB disruption. These effects were attenuated by inhibitors that blocked GJIC and Cx43 phosphorylation and expression but not Cx43 redistribution. Additionally, rtPA administration upregulated p-Cx43 expression in hypoxia/reoxygenation (H/R)-exposed brain endothelial cells. These effects were suppressed by the phosphatidylinositol 3'-kinase (PI3K) inhibitor LY294002 and the extracellular signal-regulated kinase 1/2 (ERK1/2) inhibitor U0126. We suggest that rtPA-associated hemorrhage due to an alteration in the integrity of the BBB is highly associated with an increase in p-Cx43 resulting from the activation of the PI3K and ERK pathways.

    Full Text Available Haemorrhagic transformation (HT of recently ischaemic brain is a feared complication of thrombolytic therapy that may be caused or compounded by ischaemia-induced activation of matrix metalloproteinases (MMPs. The tetracycline antibiotic minocycline inhibits matrix MMPs and reduces macroscopic HT in rodents with stroke treated with tissue plasminogen activator (tPA. The West Australian Intravenous Minocycline and TPA Stroke Study (WAIMATSS aims to determine the safety and efficacy of adding minocycline to tPA in acute ischaemic stroke. The WAIMATSS is a multicentre, prospective, and randomised pilot study of intravenous minocycline, 200 mg 12 hourly for 5 doses, compared with standard care, in patients with ischaemic stroke treated with intravenous tPA. The primary endpoint is HT diagnosed by brain CT and MRI. Secondary endpoints include clinical outcome measures. Some illustrative cases from the early recruitment phase of this study will be presented, and future perspectives will be discussed.

    We report on thrombolysis acceleration of a nanomachine powered by light-driving δ-subunit-free F0F1-ATPase motor. It is composed of a mechanical device, locating device, energy storage device, and propeller. The rotory δ-subunit-free F0F1-ATPase motor acts as a mechanical device, which was obtained by reconstructing an original chromatophore extracted from Rhodospirillum rubrum. We found that the bioactivity of the F0F1-ATPase motor improved greatly after reconstruction. The zeta potential of the nanomachine is about -23.4 mV. Cytotoxicity induced by the nanomachine was measured using cell counting kit (CCK)-8 assay. The A549 cells incubated with different fractional concentrations of the nanomachine within 48 h did not show obvious cytotoxicity. The locating device helps the nanomachine bind to the thrombi. Energy was easily stored by exposing the nanomachine to 600-nm-wavelength irradiation, which promoted activity of the motor. The rotation of the long propeller accelerated thrombolysis of a blood clot in vitro in the presence of urokinase (UK). This result was based on visual inspection and confirmed by a series of tests.

    Full Text Available Abstract Background - Experimental studies have shown that ultrasound contrast agents enhance the effectiveness of thrombolytic agents in the presence of ultrasound in vitro and in vivo. Recently, we have launched a clinical pilot study, called "Sonolysis", to study this effect in patients with ST-elevation myocardial infarction based on proximal lesions of the infarct-related artery. Methods/design - In our multicenter, randomized, placebo controlled clinical trial we will include patients between 18 and 80 years of age with their first ST-elevation myocardial infarction based on a proximal lesion of the infarct-related artery. After receiving a single bolus alteplase 50 mg IV (Actilyse® Boehringer Ingelheim GmbH, a loading dose of aspirin 500 mg, and heparin 5000 IU in the ambulance according to the prehospital thrombolysis protocol, patients, following oral informed consent, are randomized to undergo 15 minutes of pulsatile ultrasound with intravenous administration of ultrasound contrast agent or placebo without ultrasound. Afterwards coronary angiography and, if indicated, percutaneous coronary intervention will take place. A total of 60 patients will be enrolled in approximately 1 year. The primary endpoints are based on the coronary angiogram and consist of TIMI flow, corrected TIMI frame count, and myocardial blush grade. Follow-up includes 12-lead ECG, 2D-echocardiography, cardiac MRI, and enzyme markers to obtain our secondary endpoints, including the infarct size, wall motion abnormalities, and the global left ventricular function. Discussion - The Sonolysis study is the first multicenter, randomized, placebo controlled clinical trial investigating the therapeutic application of ultrasound and microbubbles in acute ST-elevation myocardial infarction patients. A positive finding may stimulate further research and technical innovations to implement the treatment in the ambulance and maybe obtain even more patency at an earlier stage

  17. Thrombolysis for treating deep venous thrombosis by high-dose urokinase: the usefulness of preventive placement of inferior vena cava filter

    International Nuclear Information System (INIS)

    Objective: To investigate the feasibility and efficacy of high-dose urokinase thrombolysis for treating lower limb deep venous thrombosis (DVT) after inferior vena cava (IVC) filter placement. Methods: Thirteen patients of venographically proved DVT underwent preventive IVC filter placement for thrombolysis by high-dose urokinase. Antegrade infusion of high-dose urokinase was performed via the dorsalis pedis vein of the involved lower limb. The total dose of urokinase was 9 000 000 ∼ 16 000 000 units, and the procedure of thrombolysis was performed in ICU ward where the patients were closely monitored clinically and laboratorially. Results: A total of 13 IVC filters were successfully deployed without disposition and migration. The therapeutic effects were divided into four scales as follows: complete disappearance of the venous thrombosis and clinically asymptomatic (n = 2); remarkable recovery characterized by markedly improved clinical symptoms and venographically proved patent lumen in which the diameter was larger than 70% (n = 9); effective treatment indicating improved symptoms to some degrees and venographically proved patent lumen in which the diameter was smaller than 70% ( n = 2); and ineffective treatment (n = 0). No pulmonary embolism and hemorrhage occurred during the procedure of thrombolysis. Conclusion: High-dose urokinase for treating DVT is safe and effective after preventive placement of IVC filter

  18. Thrombolysis together with vascular dilatation for the treatment of acute left iliofemoral venous thrombosis: which procedure should be carried out first?

    International Nuclear Information System (INIS)

    Objective: To investigate the short-term efficacy and complication occurrence of two interventional therapeutic orders, i.e. thrombolysis followed by vascular dilatation and vascular dilatation followed by thrombolysis, in treating acute left iliofemoral venous thrombosis. Methods: Forty-five patients with acute left iliofemoral venous thrombosis were divided into two groups. Patients in group A (n=21) were treated with catheter-directed thrombolysis through the catheterization of left iliofemoral vein via the left popliteal vein, and balloon dilatation or stent implantation would follow if there was any residual stenosis after thrombolysis. Patients in group B (n=24) were treated with balloon dilatation for the left iliac vein and thrombus first, which was followed by catheter-directed thrombolysis through the catheter inserted in the left iliofemoral vein via the left popliteal vein access. Stent implantation would be applied if there was any residual stenosis after thrombolysis. In all patients the optional filter was placed in the inferior vena cava and the filter was removed within two weeks. Results: In both group A and group B, balloon dilation was applied in 18 and 24 cases (P=0.09) respectively, and stenting was employed in 11 and 16 cases respectively (P=0.24). The mean urokinase used in group A was (427±49.71) × 104 unit, which was much higher than that used in group B, which was (315.00±62.48) × 104 unit. The difference between the two groups was significant (P<0.001). In group A, thrombus in cava filters was found in 2 cases and complication occurred in 7 cases. The edema reduction rate in group A was (71±19)% at one week and (98±3)% at one month after the treatment, that was (81±12)% and (99±2)% respectively in group B, thrombus in cava filters was found in 8 cases and complication occurred in 2 cases. Conclusion: For the treatment of acute left iliofemoral venous thrombosis, balloon dilatation followed by thrombolysis can well reduce the use

  19. Intra-arterial thrombolysis using rt-PA in patients with acute stroke due to vessel occlusion of anterior and/or posterior cerebral circulation

    International Nuclear Information System (INIS)

    The aim of our study was to evaluate the safety and efficacy of intra-arterial (IA) thrombolysis using recombinant tissue plasminogen activator (rt-PA) in patients with acute stroke due to occlusion in the anterior or posterior circulation. We retrospectively analyzed the clinical and radiological data of 88 consecutive patients with acute ischemic stroke who underwent emergency cerebral angiography for the purpose of subsequent IA thrombolysis. The neurological deficit on admission and discharge was graded using the National Institutes of Health Stroke Scale (NIHSS) score. Baseline computer tomography (CT) scans were examined for any signs indicative of cerebral ischemia. The angiographic findings were classified according to the Thrombolysis in Myocardial Infarction (TIMI) score for myocardial infarction. Follow-up CT scans were examined for hemorrhagic complication. Of the 88 patients who underwent IA thrombolysis, 63 presented with complete or partial arterial occlusion in the suspected perfusion area. In these 63 patients, the median NIHSS score dropped from 15 points on admission to 10 points at discharge. The recanalization rate was 52.6% for partial and complete reperfusion. In-hospital mortality was 20.6% (9.1% for carotid, 44.4% for basilar territory occlusion). Intracerebral bleeding (ICB) occurred in 38.6% of the patients with occlusion in the anterior circulation, resulting in these patients presenting a worse clinical outcome than those without ICB. Only minor extracranial bleedings occurred in 20.6% of patients. Patients with ICB had a significantly higher frequency of ischemic signs on the baseline CT scan. Occlusion of a cerebral artery is present in about 75% of the patients eligible for thrombolytic therapy. Intra-arterial thrombolysis using rt-PA in patients with acute ischemic stroke can achieve re-vascularization, although ICB remains the major risk factor affecting its efficacy. (orig.)

  1. Perfusion-CT guided intravenous thrombolysis in patients with unknown-onset stroke: a randomized, double-blind, placebo-controlled, pilot feasibility trial

    International Nuclear Information System (INIS)

    Patients with unknown stroke onset are generally excluded from acute recanalisation treatments. We designed a pilot study to assess feasibility of a trial of perfusion computed tomography (PCT)-guided thrombolysis in patients with ischemic tissue at risk of infarction and unknown stroke onset. Patients with a supratentorial stroke of unknown onset in the middle cerebral artery territory and significant volume of at-risk tissue on PCT were randomized to intravenous thrombolysis with alteplase (0.9 mg/kg) or placebo. Feasibility endpoints were randomization and blinded treatment of patients within 2 h after hospital arrival, and the correct application (estimation) of the perfusion imaging criteria. At baseline, there was a trend towards older age [69.5 (57-78) vs. 49 (44-78) years] in the thrombolysis group (n = 6) compared to placebo (n = 6). Regarding feasibility, hospital arrival to treatment delay was above the allowed 2 h in three patients (25%). There were two protocol violations (17%) regarding PCT, both underestimating the predicted infarct in patients randomized in the placebo group. No symptomatic hemorrhage or death occurred during the first 7 days. Three of the four (75%) and one of the five (20%) patients were recanalized in the thrombolysis and placebo group respectively. The volume of non-infarcted at-risk tissue was 84 (44-206) cm3 in the treatment arm and 29 (8-105) cm3 in the placebo arm. This pilot study shows that a randomized PCT-guided thrombolysis trial in patients with stroke of unknown onset may be feasible if issues such as treatment delays and reliable identification of tissue at risk of infarction tissue are resolved. Safety and efficiency of such an approach need to be established. (orig.)

    Purpose: Treatment of acute stroke by endovascular mechanical recanalisation (EMR) has shown promising results and continues to be further refined. We evaluated the impact of a temporary stent compared with our results using other mechanical devices. Materials and Methods: We analysed clinical and radiological data of all patients who were treated by EMR after intravenous thrombolysis for acute carotid T- and middle-cerebral artery (M1) occlusions at our centre between 2007 and 2011. A comparison was performed between those patients in whom solely the stent-retriever was applied (group S) and those treated with other devices (group C). Results: We identified 14 patients for group S and 16 patients for group C. Mean age, National Institute of Health Stroke Scale score, and time to treatment were 67.1 years and 16.5 and 4.0 h for group S and 61.1 years and 17.6 and 4.5 h for group C, respectively. Successful recanalisation (thrombolysis in cerebral infarction scores {>=}IIb) was achieved in 93% of patients in group S and 56% of patients in group C (P < 0.05). Mean recanalisation times for M1 occlusions were 23 min (group S) and 29 min (group C) and for carotid-T occlusions were 39 min (group S) and 50 min (group C), and 45% of the patients in group S and 33% in group C had a favourable outcome (Modified Rankin Scale score {<=}2). Conclusion: The findings suggest an improvement in recanalisation success by the application of a temporary stent compared with previously used devices. These results are to be confirmed by larger studies.

  9. Penumbra Stroke System as an ''add-on'' for the treatment of large vessel occlusive disease following thrombolysis: first results

    International Nuclear Information System (INIS)

    The Penumbra Stroke System (PSS) was cleared for use in patients with ischemic stroke by the FDA in January 2008. We describe our experience of using this new system in acute large vessel occlusive disease following thrombolysis. Fifteen consecutive patients (mean age 60 years) suffering from acute ischemic stroke were treated with the PSS after intravenous or intra-arterial standard treatment with tissue plasminogen activator (n = 14) or ReoPro (n = 1). All patients presented with TIMI 3 before use of the PSS. Carotid stenting (n = 3) and intracranial balloon angioplasty or stenting (n = 2) were performed if indicated. Neurological evaluation was performed using the NIHSS score and the mRS score. Initial median NIHSS score in 12 patients with occlusions in the anterior circulation was 15; three patients with basilar artery occlusion presented with coma. Median symptom to procedure start time was 151 min. In the anterior circulation, 9 of the 12 target vessels were recanalised successfully (TIMI 2 and 3). The rate of patients with independent clinical outcome (mRS ≤ 2) was 42%. One patient died 5 days after unsuccessful treatment, one after 28 days and one after 85 days owing to heart attack. Basilar artery occlusions could be recanalised in all cases to TIMI 3. The clinical result after 90 days was mRS 4 in two cases and mRS 5 in one case. Symptomatic haemorrhage did not occur. The PSS can safely be used for recanalisation in patients with acute ischemic stroke due to large vessel occlusion, who have already received thrombolysis treatment. The recanalisation rate was 80%. Symptomatic haemorrhage did not occur. Randomized trials may demonstrate that endovascular mechanical thrombectomy improves patient outcome. (orig.)

    On-site wastewater treatment systems (OWTSs or septic systems) are designed to treat and dispose effluents on the same property that produces the wastewater. Approximately 25% of the U.S. population is served by such facilities. Nevertheless, studies on the treatment efficiency and discharge of organic contaminants through septic effluents are lacking. This pilot study showed the occurrence of organic contaminants including pharmaceuticals and personal care products (PPCPs), perfluoroalkyl surfactants (PFASs), polybrominated diphenyl ethers (PBDEs), and polychlorinated biphenyls (PCBs) in septic effluents, adjacent lake water samples, household drinking water in homes that use lake water or a well adjacent to the lake as a source of drinking water, and offshore lake water samples. Septic effluent as well as lake and tap water samples were collected from several households with OWTSs around Skaneateles Lake located in central New York. The advanced on-site systems were installed in some households for the purpose of limiting nutrient levels in the effluent to protect the local surface water. Additionally, because many of these systems serve homes with limited land, advanced treatment systems were needed. The median concentrations of ten PPCPs (ranged from 0.45 to 388 ng/L) and eleven PFASs (ranged from 0.20 to 14.6 ng/L) in septic water were significantly higher (p ≤ 0.01) than in lake water samples. The median concentrations of PPCPs and PFASs in lake and tap water samples were not significantly different (p ≥ 0.65). The median concentrations of ∑PBDEs in septic, lake, and tap water samples were 7.47, 3.49, and 2.22 ng/L, respectively, and those for ∑PCBs were 33.1, 29.2, and 28.6 ng/L, respectively. The mass flux of PPCPs (i.e. the mass flow of PPCPs per unit area per unit time) through the disposal of treated septic effluent from textile biofilter and aerobic treatments to the dispersal unit ranged from 12 (carbamazepine) to 66900 μg/m(2)/day

However, the benefits of an additional computed tomography (aCT performed over the next days after iv-thrombolysis have not been determined.Methods: We retrospectively screened 287 Caucasian patients with ischemic stroke who were consecutively treated with iv-thrombolysis from 2008 to 2012. The results of computed tomography performed on the second (control computed tomography and seventh (aCT day after iv-thrombolysis were compared in 274 patients (95.5%; 13 subjects (4.5%, who died before the seventh day from admission were excluded from the analysis.Results: aCTs revealed a higher incidence of HT than control computed tomographies (14.2% vs 6.6%; P=0.003. Patients with HT in aCT showed higher median of National Institutes of Health Stroke Scale score on admission than those without HT (13.0 vs 10.0; P=0.01 and higher presence of ischemic changes >1/3 middle cerebral artery territory (66.7% vs 35.2%; P<0.01. Correlations between presence of HT in aCT and National Institutes of Health Stroke Scale score on admission (rpbi 0.15; P<0.01, and the ischemic changes >1/3 middle cerebral artery (phi=0.03 existed, and the presence of HT in aCT was associated with 3-month mortality (phi=0.03.Conclusion: aCT after iv-thrombolysis enables higher detection of HT, which is related to higher 3-month mortality. Thus, patients with severe middle cerebral artery infarction may benefit from aCT in the decision-making process on the secondary prophylaxis. Keywords: ischemic stroke, iv-thrombolysis

    Progress in pediatric palliative care has gained momentum, but there remain significant barriers to the appropriate provision of palliative care to ill and dying children, including the lack of properly trained health care professionals, resources to finance such care, and scientific research, as well as a continued cultural denial of death in children. This article reviews the epidemiology of pediatric palliative care, special communication concerns, decision making, ethical and legal considerations, symptom assessment and management, psychosocial issues, provision of care across settings, end-of-life care, and bereavement. Educational and supportive resources for health care practitioners and families, respectively, are included. PMID:21628042

  15. Acute care in stroke: the importance of early intervention to achieve better brain protection.

    It is known that 'time is brain', and only early therapies in acute stroke have been effective, like thrombolysis within the first 3 h, and useful neuroprotective drugs are searched for that probably would be effective only with their very early administration. General care (respiratory and cardiac care, fluid and metabolic management, especially blood glucose and blood pressure control, early treatment of hyperthermia, and prevention and treatment of neurological and systemic complications) in acute stroke patients is essential and must already start in the prehospital setting and continue at the patient's arrival to hospital in the emergency room and in the stroke unit. A review of published studies analyzing the influence of general care on stroke outcome and the personal experience from observational studies was performed. Glucose levels >8 mmol/l have been found to be predictive of a poor prognosis after correcting for age, stroke severity, and stroke subtype. Although a clinical trial of glucose-insulin-potassium infusions is ongoing, increased plasma glucose levels should be treated. Moreover, insulin therapy in critically ill patients, including stroke patients, is safe and determines lower mortality and complication rates. Both high and low blood pressure levels have been related to a poor prognosis in acute stroke, although the target levels have not been defined yet in clinical trials. The body temperature has been shown to have a negative effect on stroke outcome, and its control and early treatment of hyperthermia are important. Hypoxemia also worsens the stroke prognosis, and oxygen therapy in case of prehospital level from the very beginning. This could help to save more brain tissue to get the best conditions for further specific stroke therapies such as the use of neuroprotective or thrombolytic drugs in the hospital. PMID:14694290

    This chapter takes its point of departure in psychosocial aspects of supportive care in adolescent and young adult cancer care. The purpose is to describe some of the challenges that these young people face following a cancer diagnosis and guide healthcare professionals in how to provide care that improves the quality of life. In most hospitals and healthcare systems, adolescents and young adults are cared for and treated in settings for children or adults. Accordingly, healthcare professionals may lack attention to and knowledge about what characterize young peoples' life situation, their special needs and how to meet them. The topics we include in the chapter are the following: the youth friendly environment, social support and social network, parents, information during a psychosocial crisis event, the use of HEADSS, peer support, fertility, body image and self-esteem, after treatment and future challenges and palliative and end of life care.

    We wanted to determine whether or not the 'susceptibility asymmetry index' (SAI) of acute stroke on the T2-weighted image is related with successful recanalization using multimodal intra-arterial thrombolysis (IAT). The 81 patients who underwent multimodal IAT for middle cerebral artery (MCA) territory acute stroke were included in this retrospective study. The multimodal IAT included intra-arterial urokinase infusion, clot disruption by a microwire, microcatheter and balloon manipulation, and balloon angioplasty and/or stenting for the flow-limiting stenosis. The diameter of the susceptibility vessel sign was measured on the T2-weighted gradient echo imaging (GRE), and the diameter of the contralateral normal MCA at the corresponding level was measured on magnetic resonance angiography (MRA): the ratio between these two diameters was defined as the susceptibility asymmetry index. The relation between the TICI (Thrombolysis In Cerebral Infarction) score of 2-3 after multimodal IAT and the SAI was assessed. The receiver operating characteristic (ROC) curve analysis was performed on the SAI to predict a TICI score of 2-3 after multimodal IAT. The mean SAI of 81 patients was 1.66 {+-} 0.66. Seventy nine percent of the patients had a TICI of 2-3 after multimodal IAT. According to the ROC curve analysis, an SAI less than 1.3 was optimal for predicting the presence of stenotic lesion after recanalization (area under the curve: 0.821, sensitivity: 88.2%, specificity: 69.8%, p=0.0001), and the SAI {<=}1.61 (area under the curve: 0.652, sensitivity: 60.9%, specificity: 70.6%, p=0.0226) could predict a TICI score of 2-3. The TICI score of 2-3 after multimodal IAT was achieved in 88.6% of the cases with a SAI {<=} 1.61 and in 67.6% of the cases with a SAI >1.61 (p=0.028). The lower SAI on T2-GRE could predict stenotic lesion and successful recanalization after performing IAT

    Full Text Available Abstract Background Intravenous recombinant tissue plasminogen activator (rtPA is approved in Europe for use in patients with acute ischaemic stroke who meet strictly defined criteria. IST-3 sought to improve the external validity and precision of the estimates of the overall treatment effects (efficacy and safety of rtPA in acute ischaemic stroke, and to determine whether a wider range of patients might benefit. Design International, multi-centre, prospective, randomized, open, blinded endpoint (PROBE trial of intravenous rtPA in acute ischaemic stroke. Suitable patients had to be assessed and able to start treatment within 6 hours of developing symptoms, and brain imaging must have excluded intracranial haemorrhage and stroke mimics. Results The initial pilot phase was double blind and then, on 01/08/2003, changed to an open design. Recruitment began on 05/05/2000 and closed on 31/07/2011, by which time 3035 patients had been included, only 61 (2% of whom met the criteria for the 2003 European approval for thrombolysis. 1617 patients were aged over 80 years at trial entry. The analysis plan will be finalised, without reference to the unblinded data, and published before the trial data are unblinded in early 2012. The main trial results will be presented at the European Stroke Conference in Lisbon in May 2012 with the aim to publish simultaneously in a peer-reviewed journal. The trial result will be presented in the context of an updated Cochrane systematic review. We also intend to include the trial data in an individual patient data meta-analysis of all the relevant randomised trials. Conclusion The data from the trial will: improve the external validity and precision of the estimates of the overall treatment effects (efficacy and safety of iv rtPA in acute ischaemic stroke; provide: new evidence on the balance of risk and benefit of intravenous rtPA among types of patients who do not clearly meet the terms of the current EU approval; and

    Full Text Available Objective To investigate the reproduction of a new model of thrombosis of inferior vena cava (IVC, and explore the natural process of thrombolysis and its mechanism in rats. Methods Forty-eight SD rats were randomly classified into experimental group and control group. In the experimental group, the lumen of the vena cava was blocked by about 80%-90% with a ligature of IVC below the left renal vein, and then the animals were redivided into three subgroups (n=12, each. In group A, the IVC endothelium was damaged and its tributaries were ligated. In group B, the IVC endothelium was damaged and its tributaries were not ligated. In group C, no damage was done to the endothelium of the IVC but all its tributaries were ligated. A sham-operated group served as control. The length and weight of the vinous thrombus and the percentage of the IVC luminal area were compared after operation to determine the optimum animal model of venous thrombosis. According to the best mode to establish the model, the thrombus specimens were collected and detected by HE and Masson staining, and the ED-1 expressions were examined by immunohistochemical staining after thrombus formation in 30 rats. The natural evolution of intravenous thrombolysis was analyzed dynamically and the cell types involved in this process were observed. Results Gross observation showed that the experimental group was successfully induced thrombus formation. The thrombus length and weight in group A was significantly higher than that in group B and group C, and no difference between group B and C. The thrombus area in group A was significantly higher than that in groups B and group C, which identified the group A was the optimal model group of venous thrombosis. In the group reproduced by the best mode of the model, HE and Masson staining results showed that new capillaries and the components of collagen and extracellular matrix increased gradually with the passage of time in the process of

    Optimal multidisciplinary care of the lung cancer patient at all stages should encompass integration of the key relevant medical specialties, including not only medical, surgical, and radiation oncology, but also pulmonology, interventional and diagnostic radiology, pathology, palliative care, and supportive services such as physical therapy, case management, smoking cessation, and nutrition. Multidisciplinary management starts at staging and tissue diagnosis with pathologic and molecular phenotyping, extends through selection of a treatment modality or modalities, management of treatment and cancer-related symptoms, and to survivorship and end-of-life care. Well-integrated multidisciplinary care may reduce treatment delays, improve cancer-specific outcomes, and enhance quality of life. We address key topics and areas of ongoing investigation in multidisciplinary decision making at each stage of the lung cancer treatment course for early-stage, locally advanced, and metastatic lung cancer patients.

    Purpose: Catheter-directed thrombolysis (CDT) is a highly effective approach in the treatment of deep venous thrombosis (DVT). There are no data on the primary use of CDT with argatroban and tissue plasminogen activator (tPA) in patients without heparin-induced thrombocytopenia (HIT). The aim of this study was to evaluate the efficacy and safety of the combined administration of argatroban and tPA during CDT for massive DVT in patients without HIT. Methods: Thirty-three patients with massive symptomatic iliac and femoropopliteal DVT underwent CDT with tPA and argatroban within 28 {+-} 6 h of presentation. The dose of tPA was 0.75-1 mg/h through the infusion port and that of argatroban at 0.3-1 {mu}g/kg/min through the side port of the sheath. The patients were evaluated for the efficacy and safety of CDT and recurrent symptomatic venous thromboembolism (VTE) at a mean follow-up of 22 months. Results: There was no bleeding or iatrogenic pulmonary embolism with the CDT regimen we used. Grade III lysis (complete resolution of thrombus on venography) was achieved in 30 patients (91 %). In 3 patients with additional inferior vena cava filter thrombosis, further thrombectomy of the filter was required. No patient developed recurrent VTE. Conclusion: Concomitant administration of argatroban and tPA is a highly safe and effective regimen for CDT for massive DVT.

    International Nuclear Information System (INIS)

    To evaluate the effectiveness of percutaneous transluminal angioplasty (PTA) and pul-sed-spray pharmaco-mechanical thrombolysis (PSPMT) using urokinase for the management of insufficient hemodialysis access. Between September 1996 and May 1998, 21 insufficient hemodialysis accesses were treated in 16 patients(3 artificial arteriovenous fistulae, AVF; and 13 arteriovenous graft, AVG). PTA and PSPMT were performed in 6 and 15 cases, respectively, and success and long-term patency rates were evaluated. The overall success rate of PTA and PSPMT for insufficient hemodialysis access was 76. 2%(16/21). The success rates of PTA and PSPMT were 83.3%(5/6) and 73.3%(11/15), respectively. The primary patency rates of PSPMT were 69±12.8% at 6 months and 38±18.6% at 12 months. One of the two initially successful PTAs had been patent for 7 months, and the second PTA was performed at that time due to venous stenosis. The other was patent for 15 months throughout the follow-up period. PTA and PSPMT are effective primary methods for the treatment of insufficient hemodialysis access;success and patency rates were high, and the procedures can be performed repeatedly.=20

    Centralization of intravenous thrombolysis (IVT) for acute ischemic stroke in high-volume centers is believed to improve the door-to-needle times (DNT), but limited data support this assumption. We examined the association between DNT and IVT volume in a large Dutch province. We identified consecutive patients treated with IVT between January 2009 and 2013. Based on annualized IVT volume, hospitals were categorized as low-volume (≤ 24), medium-volume (25-49) or high-volume (≥ 50). In logistic regression analysis, low-volume hospitals were used as reference category. Of 17,332 stroke patients from 11 participating hospitals, 1962 received IVT (11.3 %). We excluded 140 patients because of unknown DNT (n = 86) or in-hospital stroke (n = 54). There were two low-volume (total 101 patients), five medium-volume (747 patients) and four high-volume hospitals (974 patients). Median DNT was shorter in high-volume hospitals (30 min) than in medium-volume (42 min, p high-volume hospitals had a higher chance of DNT centers. There was no difference in DNT between low- and medium-volume hospitals. Onset-to-needle times (ONT) did not differ between the groups. Hospitals in this Dutch province generally achieved short DNTs. Despite this overall good performance, higher IVT volumes were associated with shorter DNTs and lower complication risks. The ONT was not associated with IVT volume. PMID:26946499

    Objective: To explore the causes and preventive measures of symptomatic intracranial hemorrhage in 217 patients with acute cerebral ischemic stroke treated with local intra-arterial urokinase. Methods: From February 1999 to June 2004, 217 patients were treated for acute ischemic stroke with local intra-arterial urokinase in our hospital. Factors associated with symptomatic intracranial hemorrhage of intra-arterial thrombolysis were analyzed by Stepwise logistic regression to identify some factors relating the prediction symptomatic intracranial hemorrhage. Results: Symptomatic intracranial hemorrhage occurred in 8 cases (3.7%). Predictors of the symptomatic intracranial hemorrhage were the elevated systolic blood pressure before therapy (odds ratio, 1.096; 95% CI, 1.006 to 1.194) and urokinase (UK) treatment (odds ratio, 1.068 ; 95% CL, 1.053 to 1.247). Risk of secondary symptomatic intracranial hemorrhage was increased with elevated systolic blood pressure. Other factors like age, initial treating time, NIHSS, diabetes and collateral circulation did not predict the symptomatic intracranial hemorrhage respectively. Conclusions: Predictors of symptomatic intracranial hemorrhage after local intra-arterial infusion of urokinase for acute ischemic stroke were the elevated systolic blood pressure before therapy and urokinase (UK) treatment.

  19. Assessment of right ventricular dysfunction and the metergasis before and after therapy of thrombolysis with electrocardiography gated multi-detector spiral CT in acute pulmonary embolism

    International Nuclear Information System (INIS)

    Objective: To prospectively assess right ventricular dysfunction and the metergasis before and after therapy of thrombolysis with ECG gated multi-detector spiral computed tomography (MSCT) in patients with acute pulmonary embolism. Methods: Triple rule-out ECG gated MSCT examination was performed in 96 consecutive patients suspected of PE. 25 patients with central PE were confirmed. 25 age- matched subjects without cardiac and pulmonary disease were recruited as control group. Triple rule-out ECG gated MSCT were performed again to assess cardiac function after therapy of thrombolysis. Dimension ratios for the right ventricle (RV) and left ventricle (LV), main pulmonary artery and aorta were measured. Furthermore, the RV and LV end-diastolic volumes (EDV), end-systolic volume (ESV) and ejection fraction (EF) were also measured. The mean values were compared with analysis of variance (ANOVA) and Newman-Keuls test before and after thrombolysis. Results: The mean values of RVEDV, RVESV, RVEF, RV/LV ESV volume ratio, RV/LV dimension ratio and main pulmonary artery/aorta dimension ratio in control group were (150.5±24.1) ml, (71.5±18.5) ml, (53.5±4.2)%, 1.08±0.04, 1.01±0.04 and 0.99±0.02, respectively. While those in PE group were (190.3±16.2) ml, (128.1±13.2) ml, (32.7±3.6)%, 2.00±0.26, 1.30±0.09 and 1.34±0.11, respectively. Those after therapy of thrombolysis were (159.2±21.5) ml, (80.7±9.4) ml, (49.2±5.9)%, 1.22±0.25, 1.02±0.02 and 1.02±0.11, respectively. ESV and EDV of RV were larger (q=6.28, P<0.01; q=7.59, P<0.01), EF value was lower (q=4.82, P<0.01) in PE group than those in control group. RV/LV ESV volume ratio, the RV/LV dimension ratio and main pulmonary artery/aorta dimension ratio were larger (q=6.04, P<0.01; q=4.43, P<0.01; q=4.36, P<0.01) and EDV of LV was lower in PE group than those in control group. However, ESV and EDV of RV and RV/LV ESV volume ratio were lower (q=5.03, P< 0.01; q=6.11, P<0.01; q=4.74, P<0.01), EF value was larger (q

    Acute thrombosis of the basilar artery has a fatal outcome if left untreated. The relatively good prognosis with intra-arterial thrombolysis makes it the therapy of choice for acute basilar thrombosis. In the Saarland stroke registry, we analyzed 47 patients with angiographically proven basilar artery thrombosis within the last 5 years. We observed a better outcome in patients with good income, with recanalization, and a short time between onset of symptoms and start of thrombolysis. The complications, such as intracerebral bleedings, occurred only in the group treated with rt-PA. Intra-arterial thrombolysis with urokinase or rt-PA is a relatively safe therapy, but should be performed in neuroradiological centers. With progressing symptoms the therapeutic window can be stretched up to 12 h, but coma lasting for more than 4 h is related to a bad outcome. (orig.) [German] Der akute Verschluss der A. basilaris fuehrt unbehandelt in der Regel rasch zum Tod. Aufgrund des zumeist fatalen Ausgangs unbehandelter Basilaristhrombosen und der relativ guten Prognose bei Behandlung mit lokaler intraarterieller Thrombolyse wird diese Therapie als das Mittel der Wahl bei akuter Basilaristhrombose angesehen. Anhand des Saarlaendischen Schlaganfallregisters wurden 47 Patienten mit einer nachgewiesenen Basilaristhrombose ueber einen Zeitraum von 5 Jahren in diese Studie eingeschlossen. Es konnte nachgewiesen werden, dass eine kurze Zeit bis zum Therapiebeginn, ein gutes Income sowie eine erfolgreiche Rekanalisation mit einem guten klinischen Outcome korreliert waren. Komplikationen traten ausnahmslos bei einer Lysetherapie mit rt-PA auf. Die intraarterielle Behandlung von Basilarisverschluessen mit Urokinase oder rt-PA sollte an spezialisierten, interventionellangiographisch taetigen Zentren vorgenommen werden. Bei fluktuierendem Beginn kann das Zeitfenster bis zu 12 h betragen, nach einer Komadauer von mehr als 4 h ist in der Regel kein guenstiges Outcome zu erwarten. (orig.)

  2. The Fate of High-Density Lesions on the Non-contrast CT Obtained Immediately After Intra-arterial Thrombolysis in Ischemic Stroke Patients

    International Nuclear Information System (INIS)

    Hyperdense lesions can frequently be observed on the CT obtained immediately after intra-arterial (IA) thrombolysis, and it is sometimes difficult to differentiate contrast extravasation from the hemorrhagic lesions. The purposes of this study are to classify the hyperdense lesions according to their morphologic features and to track the outcome of those lesions. Among the 94 patients who suffered with anterior circulation ischemic stroke and who were treated with IA thrombolysis, 31 patients revealed hyperdense lesions on the CT obtained immediately after the procedure. The lesions were categorized into four types according to their volume, shape, location and density: cortical high density (HD), soft HD, metallic HD and diffuse HD. The follow-up images were obtained 3 5 days later in order to visualize the morphologic changes and hemorrhagic transformation of the lesions. Among the 31 patients with HD lesions, 18 (58%) showed hemorrhagic transformation of their lesion, and six of them were significant. All the cortical HD lesions (n = 4) revealed spontaneous resolution. Seven of the soft HD lesions (n = 13) showed spontaneous resolution, while the rest of the group showed hemorrhagic transformation. Among them the hemorrhage was significant in only two patients (2/6) who did not achieve successful recanalization. All the metallic HD lesions (n = 10) resulted in hemorrhagic transformation; among them, three cases (30%) with a maximum CT value more than 150 HU (Hounsfield unit) subsequently showed significant hemorrhagic transformation on the follow-up CT. There were four diffuse HD lesions, and two of them showed hemorrhagic transformation. The parenchymal hyperdense lesions observed on the CT obtained immediately after IA thrombolysis in ischemic stroke patients exhibited varying features and they were not always hemorrhagic. Most of the soft HD lesions were benign, and although all of the metallic HD lesions were hemorrhagic, some of them were ultimately found

  4. Acute Superior Mesenteric Venous Thrombosis: Transcatheter Thrombolysis and Aspiration Thrombectomy Therapy by Combined Route of Superior Mesenteric Vein and Artery in Eight Patients

    International Nuclear Information System (INIS)

    PurposeTo assess the feasibility, effectiveness, and safety of catheter-directed thrombolysis and aspiration thrombectomy therapy by combined route of superior mesenteric vein and artery (SMV+SMA) for acute superior mesenteric venous thrombosis (ASMVT).MethodsThis retrospective study reviewed eight ASMVT patients with transcatheter direct thrombolysis and aspiration thrombectomy therapy via SMV and indirect thrombolysis via SMA during a period of 14 months. The demographics, etiology, risk factors, therapeutic effect, complications, mortality, and follow-up of the study population were assessed. Anatomic and imaging classification of location and extent of thrombus at diagnosis and degree of thrombus lysis were described.ResultsTechnical success was achieved with substantial improvement in symptoms and thrombus resolution after thrombolytic therapy in all patients. The local urokinase infusion by SMA and SMV was performed for 5–7 (6.13 ± 0.83) and 7–15 (12 ± 2.51) days. Anticoagulation was performed catheter-directed and then orally throughout hospitalization and after discharge. Four patients required delayed localized bowel resection after thrombolytic therapy with no death. Thrombolytic therapy was not interrupted despite minor bleeding at the puncture site in two patients and sepsis in another two postoperatively. Nearly complete removal of thrombus was demonstrated by contrast-enhanced CT scan and portography before discharge. Patients were discharged in 10–27 (19.25 ± 4.89) days after admission. No recurrence developed during the follow-up of 10–13 (12.13 ± 0.99) months.ConclusionsCatheter-directed thrombolytic and aspiration therapy via SMV+SMA is beneficial for ASMVT in avoiding patient death, efficient resolving thrombus, rapid improving symptoms, reversing extensive intestinal ischemia, averting bowel resection, or localizing infarcted bowel segment and preventing short bowel syndrome

    Obese patients have complex needs that complicate their care during hospitalization. These patients often have comorbid conditions, including hypertension, heart failure, obstructive sleep apnea, pressure ulcers, and difficulty with mobility. Obese patients may be well served in the progressive care setting because they may require more intensive nursing care than can be delivered in a general care unit. Progressive care nurses have core competencies that enable them to safely and effectively care for obese patients. A plan of care with interdisciplinary collaboration illustrates the integrative care for obese progressive care patients. (Critical Care Nurse 2016; 36[4]:58-63). PMID:27481802

    Full Text Available Basilar artery thrombosis has high morbidity and mortality. Though intra-arterial thrombolytics have proven efficacy in the treatment of acute basilar artery occlusion, the elevation of procoagulant factors in the blood after intra-arterial thrombolysis could result in subsequent thrombus formation and clinical deterioration. Glycoprotein IIb/IIIa inhibitors have been shown to reduce this elevation in procoagulants. We present a pilot study of three cases of acute basilar artery occlusion treated with a combination of intra-arterial thrombolytics and Gp IIb/IIIa inhibitor with remarkable clinical recovery seen in all the patients.

    In-hospital delay reduces the benefit of intravenous thrombolysis (IVT) in acute ischemic stroke (AIS), while factors affecting in-hospital delay are less well known in Chinese. We are aiming at determining the specific factors associated with in-hospital delay through a hospital based cohort. In-hospital delay was defined as door-to-needle time (DTN) ≥60 min (standard delay criteria) or ≥75% percentile of all DTNs (severe delay criteria). Demographic data, time intervals [onset-to-door time (OTD), DTN, door-to-examination time (DTE), door-to-imaging time (DTI), door-to-laboratory time (DTL) and final-test-to-needle time (FTN, the time interval between the time obtaining the result of the last screening test and the needle time)], medical history and additional variables were calculated using Mann-Whitney U or Pearson Chi-Square tests for group comparison, and multivariate linear regression analysis was performed to identify independent variables of in-hospital delay. A total of 202 IVT cases were enrolled. The median age was 61 years and 25.2% were female. The cutoff points for the upper quartile of DTN (severe delay criteria) was 135 min.When compared with the reference group without in-hospital delay, older age, shorter OTD and less referral were found in the standard delay group and male sex, presence with transient ischemic attacks or rapidly improving symptom, and with multi-model CT imaging were more frequent in the severe delay group. In the multivariate linear regression analysis, FTN (Pdecision-making process and laboratory tests contributed the most. Efforts aiming at reducing the delay should be focused on the optimization for the items of screening tests and improvement of the pathway organization. PMID:26575839

  11. Influential factors of clinical outcome of local intra-arterial thrombolysis using urokinase in patients with hyperacute ischemic stroke

    International Nuclear Information System (INIS)

    To evaluate the clinical outcome and other relevant factors in cases where local intra-arterial thrombolysis (LIT) is used for the treatment of hyperacute ischemic stroke. Forty-eight hyperacute ischemic stroke patients were treated by LIT, using urokinase, within six hours of ictus, and for evaluation of their neurological status, the national institutes of health stroke scale (NIHSS) score was used. Angiography recanalization was classified according to Mori recanalization grades. Three months after LIT, the outcome was assessed by clinical examination using the modified rankin scale (good outcome: RS=0-3; poor outcome: RS=4-6). In all patients, the findings of pre- and post- LIT CT, and angiography, as well as neurological status and hemorrhagic complications, were also analysed. Thirty-three patients had occlusions of the middle cerebral artery (MCA), and 15, of the internal carotid artery (ICA). The NIHSS score averaged 16.9 at the onset of therapy and 13.5 at 24 hours later. Successful recanalization (Mori grade 3,4) was achieved in 28 (58.3%) of 48 patients, but in 20 (41.7%) the attempt failed. Twenty-two (45.8%) of the 48 patients had a good outcome, but in (54.2%) the outcome was poor. Thirteen (40.6%) of 32 patients with MCA occlusions and 13 (81.2%) of 16 with ICA occlusions had a poor outcome. Eight patients (16.7%) died. Overall, hemorrhages occured in 20 (41.7%) of 48 patients, with symptomatic hemorrhage in ten. Five (50%) of these ten died. LIT using urokinase for hyperacute ischemic stroke is feasible; patients with MCA occlusions had better outcomes than those with ICA occlusions. Hemorrhagic complications of LIT were frequent, and in cases of symptomatic hemorrhage a fatal outcome may be expected

    In the management of acute ischemic stroke, guideline adherence is often suboptimal, particularly for intravenous thrombolysis or anticoagulation for atrial fibrillation. We sought to improve stroke care quality via a collaborative model, the Breakthrough Series (BTS)-Stroke activity, in a nationwide, multi-center activity in Taiwan. A BTS Collaborative, a short-term learning system for a large number of multidisciplinary teams from hospitals, was applied to enhance acute ischemic stroke care quality. Twenty-four hospitals participated in and submitted data for this stroke quality improvement campaign in 2010-2011. Totally, 14 stroke quality measures, adopted from the Get With The Guideline (GWTG)-Stroke program, were used to evaluate the performance and outcome of the ischemic stroke patients. Data for a one-year period from 24 hospitals with 13,181 acute ischemic stroke patients were analyzed. In 14 hospitals, most stroke quality measures improved significantly during the BTS-activity compared with a pre-BTS-Stroke activity period (2006-08). The rate of intravenous thrombolysis increased from 1.2% to 4.6%, door-to-needle time ≤60 minutes improved from 7.1% to 50.8%, symptomatic hemorrhage after intravenous thrombolysis decreased from 11.0% to 5.6%, and anticoagulation therapy for atrial fibrillation increased from 32.1% to 64.1%. The yearly composite measures of five stroke quality measures revealed significant improvements from 2006 to 2011 (75% to 86.3%, p<0.001). The quarterly composite measures also improved significantly during the BTS-Stroke activity. In conclusion, a BTS collaborative model is associated with improved guideline adherence for patients with acute ischemic stroke. GWTG-Stroke recommendations can be successfully applied in countries besides the United States. PMID:27487190

  16. And why not thrombolysis in the ambulance (at least for some)?

    The fear that alteplase may aggravate primary intracerebral hemorrhages has led to the mandatory prerequisite for prealteplase imaging in all acute stroke patients in order to exclude such hemorrhages. Consequently, in a situation in which "time is brain," administration of alteplase is delayed until the patients are transferred to a hospital where such imaging is available, at the cost of additional ischemic damage to the brain parenchyma. Yet, theoretical considerations and empirical data suggest that alteplase's effects on primary intracerebral hemorrhages may not be that detrimental. Moreover, at least some of the patients who are at a high risk of having primary cerebral bleeds, or at a high risk of developing symptomatic secondary bleeds, can be excluded from alteplase therapy on clinical grounds, and using nonimaging point-of-care devices, before their hospital arrival. We propose that clinical research should be initiated to define a population of stroke patients in whom alteplase may be administered preimaging, resulting in a greater benefit than harm and in improved functional outcome compared to deferred, postimaging, alteplase treatment.

    Full Text Available FUNDAMENTO: Existe evidência de que a trombólise pré-hospitalar melhora os desfechos no infarto agudo do miocárdio (IAM com supradesnivelamento do segmento ST. OBJETIVO: Comparar as relações de custo-efetividade entre trombólise pré-hospitalar e trombólise intra-hospitalar para o IAM com supradesnivelamento do segmento ST, pela perspectiva do Sistema Único de Saúde. MÉTODOS: Modelo analítico de decisão foi utilizado para comparar as duas estratégias. O desfecho do estudo foi "anos de vida ganhos". O uso de recursos e os custos foram estimados pela perspectiva do Sistema Único de Saúde. Árvore de decisão e modelo de Markov foram construídos com resultados de ensaios clínicos publicados. Os custos foram valorados em real (R$, para o ano de 2005. RESULTADOS: Para um horizonte de tempo de vinte anos, a expectativa de vida média com a trombólise pré-hospitalar foi de 11,48 anos e a trombólise intra-hospitalar proporcionou expectativa de vida média de 11,32 anos. Os custos foram de R$ 5.640,00 para a trombólise pré-hospitalar e de R$ 5.816,00 para a trombólise intra-hospitalar. Houve custo adicional de R$ 176,00 por paciente com a trombólise intra-hospitalar. A trombólise pré-hospitalar proporcionou adicional de 0,15 ano de expectativa de vida comparado à trombólise intra-hospitalar. CONCLUSÃO: Esse modelo sugere que, pela perspectiva do Sistema Único de Saúde, implementar a trombólise pré-hospitalar para o IAM com supradesnivelamento do segmento ST pode representar sobrevida extra e menor custo que comparativamente à trombólise intra-hospitalar.BACKGROUND: There is evidence that prehospital thrombolysis improves the outcome in ST-elevation myocardial infarction (STEMI.

    To evaluate the factors affecting the time between symptom onset and hospital arrival in patients with acute myocardial infarction (AMI), we gave a detailed questionnaire to all who were admitted or transferred with AMI from January 1988 to February 1989. In these 126 patients (94 men, 32 women) the mean prehospital time was 5.9 +/- 11.0 hours (median 2.0, range 0.4 to 69.0). The time between symptom onset and reaching a decision that medical care should be sought was 62% of the mean prehospital time. In 100 (79%) patients, the prehospital time was less than or equal to 6 hours; of these, 61 (61%) were retrospectively judged to have been optimal candidates for lytic therapy. Stepwise multiple regression selected the following 4 variables as independent predictors of prehospital time: slow symptom progression; low income; female gender; and advanced age. All of these variables are predictive (p less than 0.03) of increased prehospital time; absence of prior AMI was of borderline additional significance (p = 0.053). Similarly, logistic regression analysis selected slow symptom progression, female gender and low income as significant (p less than or equal to 0.02) independent predictors of prehospital time greater than 6 hours. The logistic regression model incorporating these 3 variables had a sensitivity of 54%, a specificity of 95% and a positive predictive value of 72% in identifying patients with prehospital time greater than 6 hours. Thus, these data indicate it is possible to characterize patients likely to experience undue prehospital delay during AMI, which may be of importance to future public education efforts. PMID:2353644

    2016-01-01

    The value of nursing care as well as the contribution of individual nurses to clinical outcomes has been difficult to measure and evaluate. Existing health care financial models hide the contribution of nurses; therefore, the link between the cost and quality o nursing care is unknown. New data and methods are needed to articulate the added value of nurses to patient care. The final results and recommendations of an expert workgroup tasked with defining and measuring nursing care value, including a data model to allow extraction of key information from electronic health records to measure nursing care value, are described. A set of new analytic metrics are proposed. PMID:27055306

    Full Text Available Abstract Background Thrombolysis is a dynamic and time-dependent process influenced by the haemodynamic conditions. Currently there is no model that allows for time-continuous, non-contact measurements under physiological flow conditions. The aim of this work was to introduce such a model. Methods The model is based on a computer-controlled pump providing variable constant or pulsatile flows in a tube system filled with blood substitute. Clots can be fixed in a custom-built clot carrier within the tube system. The pressure decline at the clot carrier is measured as a novel way to measure lysis of the clot. With different experiments the hydrodynamic properties and reliability of the model were analyzed. Finally, the lysis rate of clots generated from human platelet rich plasma (PRP was measured during a one hour combined application of diagnostic ultrasound (2 MHz, 0.179 W/cm2 and a thrombolytic agent (rt-PA as it is commonly used for clinical sonothrombolysis treatments. Results All hydrodynamic parameters can be adjusted and measured with high accuracy. First experiments with sonothrombolysis demonstrated the feasibility of the model despite low lysis rates. Conclusions The model allows to adjust accurately all hydrodynamic parameters affecting thrombolysis under physiological flow conditions and for non-contact, time-continuous measurements. Low lysis rates of first sonothrombolysis experiments are primarily attributable to the high stability of the used PRP-clots.

    This study sought to determine whether the permeability related parameter K(trans), derived from computed tomography perfusion (CTP) imaging, can predict hemorrhagic transformation (HT) in patients with acute ischemic stroke who receive intra-arterial thrombolysis. Data from patients meeting the criterion were examined. CTP was performed and K(trans) maps were used to assess the permeability values in HT and non-HT regions. A receiver operating characteristic (ROC) curve was calculated, showing the sensitivity and specificity of K(trans) for predicting HT risk. Composite images were produced to illustrate the spatial correlations among perfusion, permeability changes and HT. This study examined 41 patients. Twenty-six patients had hemorrhagic infarction and 15 had parenchymal hemorrhage. The mean K(trans) value in HT regions was significantly lower than that in the non-HT regions (0.26 ± 0.21/min vs. 0.78 ± 0.64/min; P < 0.001). The ROC curve analysis identified an optimal cutoff value of 0.334/min for K(trans) to predict HT risk. Composite images suggested ischemic regions with low permeability, or the mismatch area of low perfusion and high permeability, more likely have HT. HT regions after intra-arterial thrombolysis had lower permeability values on K(trans) maps. The mismatch area of lower perfusion and higher permeability are more likely to develop HT. PMID:27302077

    Full Text Available Introduction: Management of stroke in the remote rural areas in India faces major challenges because of lack of awareness. Stroke care services can be optimally implemented only if the communities have an understanding of the disease. Method: A population based, cross sectional survey of an adult general population sample between the ages of 31-60 years in a rural block in Tamil Nadu, India was carried out to study their knowledge, attitude, beliefs about cause, signs and symptoms, preventive measures and treatment options of stroke. Results: Of the 174 subjects studied only 69% were aware of the term stroke and 63% were able to list the symptoms. Only a little more than half the participants (58% were aware that diabetes, smoking and hypertension are risk factors for stroke. None of the participants were aware of the endovascular thrombolysis injection for better recovery from stroke. About quarter (23% of the participants did not think that the stroke is an emergency condition and they need to take the patient urgently to the hospital. Only 56% of the participants had checked their blood pressure and 49% for diabetes. A history of having either hypertension or diabetes and stroke in the family was the only factor that was significantly associated with better awareness (p=<0.001 independent of other potential facilitating factors including age, occupation, education and gender. Conclusion: There is a need to educate the rural communities about the risk factors, how to recognize the onset, the preventive measures and optimum care of stroke to reduce the burden.

    Full Text Available In-hospital delay reduces the benefit of intravenous thrombolysis (IVT in acute ischemic stroke (AIS, while factors affecting in-hospital delay are less well known in Chinese. We are aiming at determining the specific factors associated with in-hospital delay through a hospital based cohort. In-hospital delay was defined as door-to-needle time (DTN ≥60 min (standard delay criteria or ≥75% percentile of all DTNs (severe delay criteria. Demographic data, time intervals [onset-to-door time (OTD, DTN, door-to-examination time (DTE, door-to-imaging time (DTI, door-to-laboratory time (DTL and final-test-to-needle time (FTN, the time interval between the time obtaining the result of the last screening test and the needle time], medical history and additional variables were calculated using Mann-Whitney U or Pearson Chi-Square tests for group comparison, and multivariate linear regression analysis was performed to identify independent variables of in-hospital delay. A total of 202 IVT cases were enrolled. The median age was 61 years and 25.2% were female. The cutoff points for the upper quartile of DTN (severe delay criteria was 135 min.When compared with the reference group without in-hospital delay, older age, shorter OTD and less referral were found in the standard delay group and male sex, presence with transient ischemic attacks or rapidly improving symptom, and with multi-model CT imaging were more frequent in the severe delay group. In the multivariate linear regression analysis, FTN (P<0.001 and DTL (P = 0.002 were significantly associated with standard delay; while DTE (P = 0.005, DTI (P = 0.033, DTL (P<0.001, and FTN (P<0.001 were positively associated with severe delay. There was not a significant change in the trend of DTNs during the study period (P = 0.054. In-hospital delay was due to multifactors in China, in which time delays of decision-making process and laboratory tests contributed the most. Efforts aiming at reducing the delay

    Full Text Available Abstract Background The ergotamine tartrate associated with certain categories of drugs can lead to critical ischemia of the extremities. Discontinuation of taking ergotamine is usually sufficient for the total regression of ischemia, but in some cases it could be necessary thrombolytic and anticoagulant therapy to avoid amputation. Case report A woman of 62 years presented with a severe pain left forearm appeared 10 days ago, with a worsening trend. The same symptoms appeared after 5 days also in the right forearm. Physical examination showed the right arm slightly hypothermic, with radial reduced pulse in presence of reduced sensitivity. The left arm was frankly hypothermic, pulse less on radial and with an ulnar humeral reduced pulse, associated to a decreased sensitivity and motility. Clinical history shows a chronic headache for which the patient took a daily basis for years Cafergot suppository (equivalent to 3.2 mg of ergotamine. From about ten days had begun therapy with itraconazole for vaginal candidiasis. The Color-Doppler ultrasound shown arterial thrombosis of the upper limbs (humeral and radial bilateral, with minimal residual flow to the right and no signal on the humeral and radial left artery. Results Angiography revealed progressive reduction in size of the axillary artery and right humeral artery stenosis with right segmental occlusions and multiple hypertrophic collateral circulations at the elbow joint. At the level of the right forearm was recognizable only the radial artery, decreased in size. Does not recognize the ulnar, interosseous artery was thin. To the left showed progressive reduction in size of the distal subclavian and humeral artery, determined by multiple segmental steno-occlusion with collateral vessels serving only a thin hypotrophic interosseous artery. Arteriographic findings were compatible with systemic drug-induced disease. The immediate implementation of thrombolysis, continued for 26 hours, with

  13. Integrating palliative care into comprehensive cancer care.

    Abrahm, Janet L

    2012-10-01

    While there are operational, financial, and workforce barriers to integrating oncology with palliative care, part of the problem lies in ourselves, not in our systems. First, there is oncologists' "learned helplessness" from years of practice without effective medications to manage symptoms or training in how to handle the tough communication challenges every oncologist faces. Unless they and the fellows they train have had the opportunity to work with a palliative care team, they are unlikely to be fully aware of what palliative care has to offer to their patients at the time of diagnosis, during active therapy, or after developing advanced disease, or may believe that, "I already do that." The second barrier to better integration is the compassion fatigue many oncologists develop from caring for so many years for patients who, despite the oncologists' best efforts, suffer and die. The cumulative grief oncologists experience may go unnamed and unacknowledged, contributing to this compassion fatigue and burnout, both of which inhibit the integration of oncology and palliative care. Solutions include training fellows and practicing oncologists in palliative care skills (eg, in symptom management, psychological disorders, communication), preventing and treating compassion fatigue, and enhancing collaboration with palliative care specialists in caring for patients with refractory distress at any stage of disease. As more oncologists develop these skills, process their grief, and recognize the breadth of additional expertise offered by their palliative care colleagues, palliative care will become integrated into comprehensive cancer care.

  14. Pre- and in-hospital intersection of stroke care.

    Meretoja, Atte; Kaste, Markku

    2012-09-01

    Acute ischemic stroke is a time-critical emergency for which thrombolytic therapy is the only medical treatment. Many patients who would benefit from this treatment are deprived of it due to delays. Failure to call for help rapidly is the main obstacle, but even when the call is made in time, the prehospital evaluation, transportation, and emergency department (ED) diagnostics often take too long to treat the patient with thrombolysis. Interventions to reduce pre- and in-hospital delays have been described; although no single intervention is likely to make a major difference, a whole set of interventions needs to be implemented. The intersection of the pre- and in-hospital care is of special importance. With successful protocols and good communication between the emergency medical service and ED, delays can be significantly reduced. On the basis of our experience, 94% of patients can be treated within 60 min of arrival, based largely on using the prehospital time effectively. PMID:22994234

    Previous studies have suggested a greater ischemic tolerance in posterior circulation as compared to anterior cerebral circulation. We aimed to investigate whether a differential response exists between anterior and posterior circulation strokes. Two hundred and four middle cerebral artery (MCA) patients and 28 basilar artery occlusion (BAO) patients treated with intravenous recombinant tissue plasminogen activator were included. Transcranial Doppler assessed recanalization at different time points. Patients were divided in three groups: total time of ischemia (TTI)24 hours. We calculated the percentage of recovery (admission National Institutes of Health Stroke Scale [NIHSS]- discharge NIHSS/admission NIHSS)×100. Mean time to treatment was longer in BAO patients (P=.031). Early recanalization was more frequent among MCA occlusions (41% vs 29%; P=.039); the rate of persisting occlusion at 24 hours was similar (P=.933). Clinical recovery according to TTI was similar in each group: 24 hours: BAO -44%/MCA 11% (P=.23). For each hour of ischemia MCA patients worsened 1.78% (P=.035) and BAO 1.76% (P=.421). MCA occlusions compared to BAO were independently associated with hemorrhagic transformation (OR: 8.2; P=.043). Our data do not support the theory of increased ischemic tolerance in posterior circulation. Despite longer time-to-treatment, BAO were more resistant to hemorrhagic transformations. PMID:20040010

    1998-03-01

    Mass removal experiments have been performed at the Oregon Medical Laser Center with 10 to 100 mJ 1 {micro}s laser pulses at optical wavelengths. Above the energy threshold for bubble formation, the laser mass ablation efficiency ({micro}g/mJ) for removal of gel surrogate thrombus is nearly constant for a given experimental geometry and gel absorption coefficient. The efficiency in contact experiments, in which the optical fiber delivering the energy is in close proximity to the absorbing gel, is approximately three times that of non-contact experiments, in which the optical fiber is {approximately}1 mm from the gel. Mass removal occurs hundreds of microseconds after the laser deposition. Experimental data and numerical simulations are consistent with the hypothesis that jet formation during bubble collapse plays a dominant role in mass removal. This hypothesis suggests a model in which the mass removed scales linearly with the maximum bubble volume and explains the distinctive features, including the magnitude, of the mass removal.

  18. Intravenous thrombolysis in acute ischemic stroke patients with negative CT perfusion: a case series

    International Nuclear Information System (INIS)

    Computed tomography perfusion (CTP) is a commonly used modality of neurophysiologic imaging to aid the selection of acute ischemic stroke patients for neuroendovascular intervention by identifying the presence of penumbra versus infarcted brain tissue. However many patients present with evidence of cerebral ischemia with normal CTP, and in that case, should intravenous thrombolytics be given? To demonstrate if tissue-type plasminogen activator (tPA)-eligible stroke patients without perfusion defects demonstrated on CTP would benefit from administration of intravenous thrombolytics. We retrospectively identified patients presenting with acute ischemic symptoms who received intravenous tPA (IV-tPA) from January to June 2012 without a perfusion defect on CTP. Clinical and radiographic findings including the NIHSS at presentation, 24 h, and at discharge, symptomatic and asymptomatic hemorrhagic transformation, and the modified Rankin score at 30 days were collected. A reduction of NIHSS of greater than 4 points or resolution of symptoms was considered significant. Seventeen patients were identified with a mean NIHSS of 8.2 prior to administration of intravenous thrombolytics, 3.5 after 24 h, and 2.5 at discharge. Among them, 13 patients had significant improvement of NIHSS with a mean reduction of 6.15 points at 24 h. One patient initially improved but had delayed hemorrhagic transformation and died. Two patients had improvement in NIHSS but were not significant and two patients had increased in NIHSS at 24 h, although one eventually improved at discharge. There was no asymptomatic hemorrhagic transformation. Mean mRS at 3 months is 1.76. The failure to identify a perfusion deficit by CTP should not be used as a contraindication for intravenous thrombolytics. Criteria for administration of intravenous thrombolytics should still be based on time from symptom onset as previously published by NINDS

    2011-08-01

    In Chicago, Illinois, on May 7, 2009, a group of 53 medical educators representing many U.S. certification boards, residency review committees, and medical societies met to review and approve a white paper intended to promote Recommendation 4.2 of the Institute of Medicine report of April 14, 2008, "Retooling for an Aging America: Building the Healthcare Workforce." This recommendation is one of 14 and states: "All licensure, certification and maintenance of certification for healthcare professionals should include demonstration of competence in care of older adults as a criterion." Background information given included the growing numbers of older adults, review of a 15-year initiative by a section of the American Geriatrics Society (AGS) to include geriatric education in all surgical and some related medical specialties, a recent announcement of 26 elder care competencies to be expected of graduating medical students from association of American Medical Colleges (AAMC) affiliated schools, and the American Board of Medical Specialties (ABMS) approach to 'Reinforcing Geriatric Competencies through Licensure and Certification Examinations." Nine points involved in the implementation of this recommendation received discussion, and approaches to realization were presented. In conclusion, this white paper, which those listed as being in attendance approved, proposes hat all ABMS member boards whose diplomates participate in the care of older adults select the floor competencies enumerated by the AAMC that apply to their specialty and add or subtract those completed during their trainees' initial (intern) year and then define those needed in subsequent years of residency and ultimate practice. This would fulfill the requirements of Recommendation 4.2 above. PMID:21797833

    Phlegmasia caerulea dolens (PCD) is a potentially disastrous complication of inferior vena cava filter insertion, and its optimum management has not been clearly established. We present a case report of a patient with pulmonary embolism and acute adrenal haemorrhage who developed PCD secondary to massive iliocaval thrombosis after insertion of a Cook Celect removable filter. Local intravenous catheter-directed thrombolysis (CDT), followed by systemic anticoagulation, achieved limb salvage and virtual resolution of symptoms at 3 months without complications. CDT can be a successful primary treatment of filter-associated PCD and can be safe in selected patients with acute nontraumatic haemorrhage. Systemic anticoagulation may subsequently restore complete venous patency and may therefore be a useful approach to postthrombolysis management of residual iliocaval thrombus when filter removal is indicated.

  5. Intercultural caring-an abductive model.

    2008-09-01

    The aim of this study was to increase the understanding of caring from a transcultural perspective and to develop the first outline of a theory. The theoretical perspective includes Eriksson's theory of caritative caring. Texts on caring by the transcultural theorists, including Campinha-Bacote, Kim-Godwin, Leininger and Ray, are analysed using content analysis. The overall theme that resulted from this analysis was that caring is a complex whole. Three main categories of caring emerged: inner caring, outer caring and the goal of caring. Inner caring consists of caring is a relationship, and caring and culture are seen in different dimensions. Outer caring refers to caring affected by educational, administrative and social and other structures. The goal of caring consists of caring leading to change towards health and well-being. The main categories include categories and subcategories that are compared with Eriksson's theory of caritative caring. A model for intercultural caring is generated abductively. Caring and culture appear in three dimensions: caring as ontology independent of context; caring as a phenomenon emphasised differently in different cultures; caring as nursing care activities is unique. Caring alleviates suffering and leads to health and well-being. This model describes caring from an intercultural perspective as a mutual but asymmetric relationship between the nurse and the patient, including the patient's family and community. The patient's cultural background and acculturation influence caring. The cultural background, cultural competence and organisation of the nurse also influence caring. Caring is seen as a complex whole. This study integrates Campinha-Bacote's, Kim-Godwin's, Leininger's and Ray's views of caring with Eriksson's caritative caring and presents caring from a transcultural perspective in a new way as a model for intercultural caring, which can benefit nursing care, education, research and administration.

    The elderly population consists of those over age 75 years and appears to represent the fastest-growing segment of the population.Intravenous thrombolytic therapy (TT) is the most common strategy for the treament of acute myocardial infarction (AMI) in many parts of the world. However, TT carries a higher risk of intra-cranial hemorrhage (ICH) in the elderly patients. Primary percutaneous transluminal coronary angioplasty and stenting (PCI) represents an important alternative in these elderly individuals with contraindications to TT. In developing countries, or in areas without availability of primary PCI, TT remains the only therapeutic modality. Dedicated randomized trials are needed to provide a comprehensive understanding of AMI management in the elderly group.

    Magnetic resonance imaging (MRI) may help identify acute stroke patients with a higher potential benefit from thrombolytic therapy. The aim of our study was to assess the correlation between initial cerebral infarct (CI) volume (quantified on diffusion-weighted MRI) and the resulting clinical outcome in acute stroke patients with middle cerebral artery (MCA) (M{sub 1-2} segment) occlusion detected on MRI angiography treated by intravenous/intraarterial thrombolysis. Initial infarct volume (V{sub DWI-I}) was retrospectively compared with neurological deficit evaluated using the NIH stroke scale on admission and 24 h later, and with the 90-day clinical outcome assessed using the modified Rankin scale in a series of 25 consecutive CI patients. The relationship between infarct volume and neurological deficit severity was assessed and, following the establishment of the maximum V{sub DWI-I} still associated with a good clinical outcome, the patients were divided into two groups (V{sub DWI-I} {<=}70 ml and >70 ml). V{sub DWI-I} ranged from 0.7 to 321 ml. The 24-h clinical outcome improved significantly (P=0.0001) in 87% of patients with a V{sub DWI-I} {<=}70 ml (group 1) and deteriorated significantly (P=0.0018) in all patients with a V{sub DWI-I} >70 ml (group 2). The 90-day mortality was 0% in group 1 and 71.5% in group 2. The 90-day clinical outcome was significantly better in group 1 than in group 2 (P=0.026). Clinical outcome could be predicted from initial infarct volume quantified by MRI-DWI in acute CI patients with MCA occlusion treated by intravenous/intraarterial thrombolysis. Patients with a V{sub DWI-I} {<=}70 ml had a significantly better outcome. (orig.)

    The Penumbra Stroke System (PSS) was cleared for use in patients with ischemic stroke by the FDA in January 2008. We describe our experience of using this new system in acute large vessel occlusive disease following thrombolysis. Fifteen consecutive patients (mean age 60 years) suffering from acute ischemic stroke were treated with the PSS after intravenous or intra-arterial standard treatment with tissue plasminogen activator (n = 14) or ReoPro (n = 1). All patients presented with TIMI 3 before use of the PSS. Carotid stenting (n = 3) and intracranial balloon angioplasty or stenting (n = 2) were performed if indicated. Neurological evaluation was performed using the NIHSS score and the mRS score. Initial median NIHSS score in 12 patients with occlusions in the anterior circulation was 15; three patients with basilar artery occlusion presented with coma. Median symptom to procedure start time was 151 min. In the anterior circulation, 9 of the 12 target vessels were recanalised successfully (TIMI 2 and 3). The rate of patients with independent clinical outcome (mRS {<=} 2) was 42%. One patient died 5 days after unsuccessful treatment, one after 28 days and one after 85 days owing to heart attack. Basilar artery occlusions could be recanalised in all cases to TIMI 3. The clinical result after 90 days was mRS 4 in two cases and mRS 5 in one case. Symptomatic haemorrhage did not occur. The PSS can safely be used for recanalisation in patients with acute ischemic stroke due to large vessel occlusion, who have already received thrombolysis treatment. The recanalisation rate was 80%. Symptomatic haemorrhage did not occur. Randomized trials may demonstrate that endovascular mechanical thrombectomy improves patient outcome. (orig.)

    activator(rt-PA) in patients with cerebral infarction. Methods A total of 76 ischemic stroke patients onset time within 4.5-hour were enrolled, which included 39 males and 37 females, aged 51-79 years old with mean age of 60.0 years old. The rt-PA intravenous thrombolysis was performed, and the scores before treatment and 2-hour, 24-hour, 7-day, 14-day and 90-day after treatment were observed by QEEG and evaluated with United States National Institutes of Health Stroke Scale(NIHSS). The brain symmetry index(BSI) of electroencephalograph,δ+θandα+βwave ratio(DTABR) were observed. Accorded to NIHSS score, patients with rt-PA treatment were divided into 2 groups, which were improvement group(NIHSS score improved at 14-day) and non-improvement group. Results The changes of NIHSS score in 2 groups showed that: there was statistical significant difference of NIHSS score at 7-day between 2 groups. The NIHSS score in improvement group was better than that in non-improvement group. Importantly, the changes of NIHSS score in improvement group was better at 7-day than 24-hour, but it was no change in non-improvement group(P<0.01). There was statistical significant difference of NIHSS score at 90-day between 2 groups, and the score in improvement group was better than that in non-improvement group ( P<0.01). The changes of electroencephalograph in 2 groups showed that:the changes of BSI in improvement group was better at 24-hour and DTABR at 7-day (P<0.01). In non-improvement group, BSI and DTABR were deteriorated at 24-hour but BSI improved at 7-day and DTABR improved at 14-day. The NIHSS score of patients with effective thrombolysis was improved significantly at 7-day and sustained remission to 90-day. The sooner NIHSS score improvement of rt-PA intravenous thrombolysis, the better prognosis at 90-day. The sooner BSI and DTABR improvement, the better NIHSS score, but NIHSS score improved more lately in early deterioration BSI and DTABR. Conclusion It is demonstrated that the

  1. Measuring Quality Improvement in Acute Ischemic Stroke Care: Interrupted Time Series Analysis of Door-to-Needle Time

    Directory of Open Access Journals (Sweden)

    Anne Margreet van Dishoeck

    2014-06-01

    Full Text Available Background: In patients with acute ischemic stroke, early treatment with recombinant tissue plasminogen activator (rtPA improves functional outcome by effectively reducing disability and dependency. Timely thrombolysis, within 1 h, is a vital aspect of acute stroke treatment, and is reflected in the widely used performance indicator ‘door-to-needle time' (DNT. DNT measures the time from the moment the patient enters the emergency department until he/she receives intravenous rtPA. The purpose of the study was to measure quality improvement from the first implementation of thrombolysis in stroke patients in a university hospital in the Netherlands. We further aimed to identify specific interventions that affect DNT. Methods: We included all patients with acute ischemic stroke consecutively admitted to a large university hospital in the Netherlands between January 2006 and December 2012, and focused on those treated with thrombolytic therapy on admission. Data were collected routinely for research purposes and internal quality measurement (the Erasmus Stroke Study. We used a retrospective interrupted time series design to study the trend in DNT, analyzed by means of segmented regression. Results: Between January 2006 and December 2012, 1,703 patients with ischemic stroke were admitted and 262 (17% were treated with rtPA. Patients treated with thrombolysis were on average 63 years old at the time of the stroke and 52% were male. Mean age (p = 0.58 and sex distribution (p = 0.98 did not change over the years. The proportion treated with thrombolysis increased from 5% in 2006 to 22% in 2012. In 2006, none of the patients were treated within 1 h. In 2012, this had increased to 81%. In a logistic regression analysis, this trend was significant (OR 1.6 per year, CI 1.4-1.8. The median DNT was reduced from 75 min in 2006 to 45 min in 2012 (p Conclusion and Implications: The DNT steadily improved from the first implementation of thrombolysis. Specific

    1990-04-01

    The growing recognition of the importance of early thrombolysis in evolving myocardial infarction was the basis for the present study, which evaluated the effectiveness, feasibility and safety of prehospital thrombolytic therapy. In a relatively small study, 118 patients were allocated to receive either prehospital treatment with recombinant tissue-type plasminogen activator (rt-PA) in the mobile intensive care unit (group A, 74 patients) or hospital treatment (group B, 44 patients). A total of 120 mg of rt-PA was infused over a period of 6 h. All patients were fully heparinized and underwent radionuclide left ventriculography and coronary angiography during hospitalization. Although group A was treated significantly earlier than group B after onset of symptoms (94 +/- 36 versus 137 +/- 45 min, respectively; p less than 0.001), no significant differences were observed between the groups in 1) extent of myocardial necrosis, 2) global left ventricular ejection fraction at discharge, 3) patency of infarct-related artery, 4) length of hospital stay, and 5) mortality at 60 days. However, a trend to a lower incidence of congestive heart failure at hospital discharge was observed in the prehospital-treated compared with the hospital-treated group (7% versus 16%, respectively; p = NS). No major complications occurred during transportation. It is concluded that myocardial infarction can be accurately diagnosed and thrombolytic therapy initiated relatively safely during the prehospital phase by the mobile intensive care team, thus instituting a beneficial clinical trend in favor of prehospital thrombolysis.

    Thrombotic disease is extremely harmful to human health, but early detection and treatment can help improve prognoses and reduce mortality. To date, few studies have used MR molecular imaging in the early detection of thrombi and in the dynamic monitoring of the thrombolytic efficiency. In this article, we construct Fe3O4-based poly(lactic-co-glycolic acid) (PLGA) nanoparticles to use in the detection of thrombi and in targeted thrombolysis using MRI monitoring. Cyclic arginine-glycine-aspartic peptide (cRGD) was grafted onto the chitosan (CS) surface to synthesize a CS-cRGD film using carbodiimide-mediated amide bond formation. A double emulsion solvent evaporation method (water in oil in water [W/O/W]) was used to construct Fe3O4-based PLGA nanoparticles carrying recombinant tissue plasminogen activator (rtPA) (Fe3O4-PLGA-rtPA/CS-cRGD). Fe3O4-PLGA, Fe3O4-PLGA-rtPA, and Fe3O4-PLGA-rtPA/CS nanoparticles were constructed using the same W/O/W method. The results showed that the Fe3O4-based nanoparticles were constructed successfully and have a regular shape, a relatively uniform size, a high carrier rate of Fe3O4 and encapsulation efficiency of rtPA, and a relatively high activity of released rtPA. Transmission electron microscope (TEM) images revealed that the iron oxide particles were relatively uniformly distributed in the nano-spherical shell. The Fe3O4-based nanoparticles could be imaged using a clinical MRI scanner, and there were no significant differences in the transverse relaxation rate (R2*) or in the signal-to-noise ratio (SNR) values between the Fe3O4-based nanoparticles and an Fe3O4 solution with the same concentration of Fe3O4. In vitro and in vivo experiments confirmed that the Fe3O4-PLGA-rtPA/CS-cRGD nanoparticles specifically accumulated on the edge of the thrombus and that they had a significant effect on the thrombolysis compared with the Fe3O4-PLGA, Fe3O4-PLGA-rtPA, and Fe3O4-PLGA-rtPA/CS nanoparticles and with free rtPA solution. These results

    Outbreaks and pseudo-outbreaks in health care settings can be complex and should be evaluated systematically using epidemiologic tools. Laboratory testing is an important part of an outbreak evaluation. Health care personnel, equipment, supplies, water, ventilation systems, and the hospital environment have been associated with health care outbreaks. Settings including the neonatal intensive care unit, endoscopy, oncology, and transplant units are areas that have specific issues which impact the approach to outbreak investigation and control. Certain organisms have a predilection for health care settings because of the illnesses of patients, the procedures performed, and the care provided. PMID:27515142

    Patient-centered care focuses on the patient and the individual's particular health care needs. The goal of patient-centered health care is to empower patients to become active participants in their care. This requires that physicians, radiologic technologists and other health care providers develop good communication skills and address patient needs effectively. Patient-centered care also requires that the health care provider become a patient advocate and strive to provide care that not only is effective but also safe. For radiologic technologists, patient-centered care encompasses principles such as the as low as reasonably achievable (ALARA) concept and contrast media safety. Patient-centered care is associated with a higher rate of patient satisfaction, adherence to suggested lifestyle changes and prescribed treatment, better outcomes and more cost-effective care.

They assume that the airplane is technically viable and is being piloted by competent people. Criteria for judging a particular airline are personal and include aspects like comfort, friendly service and on-time schedules. Similarly, patients judge the standard of their healthcare on nontechnical aspects, such as a healthcare practitioner's communication and "soft skills." Most are unable to evaluate a practitioner's level of technical skill or training, so the qualities they can assess become of the utmost importance in satisfying patients and providing patient-centered care.(1).

    To reduce the time from symptom onset to treatment with tissue plasminogen activator (tPA) in ischemic stroke, an ambulance was equipped with a CT scanner. We analyzed process and image quality of CT scanning during the pilot study regarding image quality and safety issues. The pilot study of a stroke emergency mobile unit (STEMO) ran over a period of 12 weeks on 5 weekdays from 7a. m. to 6:30 p. m. A teleradiological service for the justifying indication and reporting was established. The radiographer was responsible for the performance of the CT scan on the ambulance. 64 cranial CT scans and 1 intracranial CT angiography were performed. We compared times from ambulance alarm to treatment decision (time of last brain scan) with a cohort of 50 consecutive tPA treatments before implementation of STEMO. 62 (95 %) of the 65 scans performed had sufficient quality for reading. Technical quality was not optimal in 45 cases (69 %) mainly caused by suboptimal positioning of patient or eye lense protection. Motion artefacts were observed in 8 exams (12 %). No safety issues occurred for team or patients. 23 patients were treated with thrombolysis. Time from alarm to last CT scan was 18 minutes shorter than in the tPA cohort before STEMO implementation. A teleradiological support for primary stroke imaging by CT on-site is feasible, quality-wise of diagnostic value and has not raised safety issues. (orig.)

  10. Integrating palliative care into the trajectory of cancer care.

    2016-03-01

    Over the past five decades, palliative care has evolved from serving patients at the end of life into a highly specialized discipline focused on delivering supportive care to patients with life-limiting illnesses throughout the disease trajectory. A growing body of evidence is now available to inform the key domains in the practice of palliative care, including symptom management, psychosocial care, communication, decision-making, and end-of-life care. Findings from multiple studies indicate that integrating palliative care early in the disease trajectory can result in improvements in quality of life, symptom control, patient and caregiver satisfaction, illness understanding, quality of end-of-life care, survival, and costs of care. In this narrative Review, we discuss various strategies to integrate oncology and palliative care by optimizing clinical infrastructures, processes, education, and research. The goal of integration is to maximize patient access to palliative care and, ultimately, to improve patient outcomes. We provide a conceptual model for the integration of supportive and/or palliative care with primary and oncological care. We also discuss how health-care systems and institutions need to tailor integration based on their resources, size, and the level of primary palliative care available. PMID:26598947

    Alopecia can be effectively camouflaged or worsened through the use of hair care techniques and dyeing. Proper hair care, involving hair styling and the use of mild shampoos and body-building conditioners, can amplify thinning scalp hair; however, chemical processing, including hair dyeing, permanent waving, and hair straightening, can encourage further hair loss through breakage. Many patients suffering from alopecia attempt to improve their hair through extensive manipulation, which only increases problems. Frequent haircuts to minimize split ends, accompanied by gentle handling of the fragile fibers, is best. This chapter offers the dermatologist insight into hair care recommendations for the alopecia patient. PMID:26370650

    One of the primary strategies for the management of acute ischemic stroke is intravenous (IV) thrombolysis with tissue plasminogen activator (t-PA). Over the past decade, endovascular therapies such as the use of stent retrievers to perform mechanical thrombectomy have been found to improve functional outcomes compared to t-PA alone. We aimed to reassess the functional outcomes and complications of IV thrombolysis with and without endovascular treatment for acute ischemic stroke using conventional meta-analysis and trial sequential analysis. Pooled relative risks (RR) and 95% confidence intervals (CI) were calculated for the effect of IV thrombolysis with and without endovascular therapy on functional outcome, mortality and symptomatic intracranial hemorrhage (SICH). Trial sequential analysis was done to strengthen the meta-analysis. We analyzed six randomized controlled trials involving 1943 patients. Patients who received IV thrombolysis with endovascular treatment showed significantly higher rates of excellent functional outcomes (modified Rankin Scale [mRS] 0-1) (RR, 1.75 [95% CI, 1.29-2.39]) compared to those who received IV thrombolysis alone. A similar association was seen for good functional outcomes (mRS 0-2) (RR, 1.56 [95% CI, 1.24-1.96]). Trial sequential analysis demonstrated endovascular treatment increased the RR of a good functional outcome by at least 30% compared to IV thrombolysis alone. There was no significant difference in all-cause mortality for mechanical thrombectomy compared to IV thrombolysis alone or the incidence of SICH at 3month follow-up. Endovascular treatment is more likely to result in a better functional outcome for patients compared to IV thrombolysis alone for acute ischemic stroke. PMID:26947342

    Purpose: direct intra-arterial thrombolysis is the standard of care over acute surgical intervention for acute infrainguinal occlusion. However, several mechanical thrombectomy devices can be utilized as a less invasive alternative to rapid reperfusion of the acutely threatened limb. Materials end methods: retrospective analysis of 265 patients treated from 1999 to 2005, mean age 65 {+-} 8.4 (range from 47 to 75) years, with acute (85 patients, 32.1%, group 1) or subacute (180 patients, 67.9%, group 2) occlusions of the femoropopliteal artery with a rotational thromboembolectomy system (Straub Rotarex registered). The mean occlusion length was 25 (range 2 - 40) cm. Results: the technical success rate was 94.7% (251 / 265). In the additional 14 patients, no complete clot removal (n = 9) or intraluminal guidewire passage was able to be achieved (n = 5). After a mean follow-up of 12 {+-} 3 months, the restenosis rate was 49% in group 1 and 54% in group 2. The ankle-brachial index improved in group 1 from 0.32 {+-} 0.17 to 0.78 {+-} 0.24 at discharge and 0.71 {+-} 0.23 after 12 months (p {<=} 0.001) and in group 2 from preinterventional 0.47 {+-} 0.24 to 0.81 {+-} 0.19 at discharge and 0.74 {+-} 0.24 after 12 months (p {<=} 0.001).

    To control Medicaid costs, improve quality, and drive community engagement, the Oregon Health Authority introduced a new system of coordinated care organizations (CCOs). While CCOs resemble traditional Medicaid managed care, they have differences that have been deliberately designed to improve care coordination, increase accountability, and incorporate greater community governance. Reforms include global budgets integrating medical, behavioral, and oral health care and public health functions; risk-adjusted payments rewarding outcomes and evidence-based practice; increased transparency; and greater community engagement. The CCO model faces several implementation challenges. If successful, it will provide improved health care delivery, better health outcomes, and overall savings. PMID:25480844

    Children with autism may seem to not care about things or have the same range of emotions as those of us who see them and care for them. But they do have empathy and they can be taught how to communicate it, says the author, a teacher of children with autism. We simply need to listen to them, watch them, and be with them in their moment.

  8. Including Language Access into Medicaid ACO Design.

    Science.gov (United States)

    Gershon, Rachel; Morris, Lisa; Ferguson, Warren

    2016-09-01

    Quality health care relies upon communication in a patient's preferred language. Language access in health care occurs when individuals are: (1) Welcomed by providers regardless of language ability; and (2) Offered quality language services as part of their care. Federal law generally requires access to health care and quality language services for deaf and Limited English Proficient (LEP) patients in health care settings, but these patients still find it hard to access health care and quality language services.Meanwhile, several states are implementing Medicaid Accountable Care Organization (ACO) initiatives to reduce health care costs and improve health care quality. Alternative payment methods used in these initiatives can give Accountable Care Organizations more flexibility to design linguistically accessible care, but they can also put ACOs at increased financial risk for the cost of care. If these new payment methods do not account for differences in patient language needs, ACO initiatives could have the unintended consequence of rewarding ACOs who do not reach out to deaf and LEP communities or offer quality language services.We reviewed public documents related to Medicaid ACO initiatives in six states. Some of these documents address language access. More could be done, however, to pay for language access efforts. This article describes Medicaid ACO initiatives and explores how different payment tools could be leveraged to reward ACOs for increased access to care and quality language services. We find that a combination of payment tools might be helpful to encourage both access and quality. PMID:27587453

    Optimal growth and development depend not only on food quality and availability, on access to health care services and a healthy environment but also on the care provided to the child especially during the first few years of life. Care refers to the actions and practices of caregivers on a day to day basis that translate food, heakh care, and water and sanitation supplies into good growth and development of children. It includes behaviours such as feeding, sanitation and hygiene, home health practices, preparing food for children, and providing psychosocial support for development. Families also are responsible for providing care for girls in the family and women. Care requires resources--both skills and capabilities, as well as economic resources. Some resources are easily recognised, such as education of the caregiver, but others are less often seen, including time of the caregiver, motivation of caregiver and male family members, organisational resources such as child care centres, and the caregiver's ability to influence decisions about child care. It must be noted that the poorer the family, the more risks for children in the environment. Therefore, the poorer the environment, the more important a role care has in children's survival, growth and development. Implications for health care providers include assessing the care practices in the home, and resources for care when making recommendations; supporting positive practices already being performed in order to empower the caregiver; checking the understanding and recall of the caregiver; and finally, recognising that all children, regardless of gender, ethnicity, case, economic level, etc, have a right to good nutrition and health care in order to develop to their fullest potential under the Convention for the Rights of the Child, acceded to by India in 1992.

    2016-01-01

    This update comprises six important topics under neurocritical care that require reevaluation. For post-cardiac arrest brain injury, the evaluation of the injury and its corresponding therapy, including temperature modulation, is required. Analgosedation for target temperature management is an essential strategy to prevent shivering and minimizes endogenous stress induced by catecholamine surges. For severe traumatic brain injury, the diverse effects of therapeutic hypothermia depend on the complicated pathophysiology of the condition. Continuous electroencephalogram monitoring is an essential tool for detecting nonconvulsive status epilepticus in the intensive care unit (ICU). Neurocritical care, including advanced hemodynamic monitoring, is a fundamental approach for delayed cerebral ischemia following subarachnoid hemorrhage. We must be mindful of the high percentage of ICU patients who may develop sepsis-associated brain dysfunction. PMID:27239312

    2009-12-01

    Full Text Available Abstract Background Although primary care should be the cornerstone of medical practice, inappropriate use of urgent care for non-urgent patients is a growing problem that has significant economic and healthcare consequences. The characteristics of patients who choose the urgent care setting, as well as the reasoning behind their decisions, is not well established. The purpose of this study was to determine the motivation behind, and characteristics of, adult patients who choose to access health care in our urgent care clinic. The relevance of understanding the motivation driving this patient population is especially pertinent given recent trends towards universal healthcare and the unclear impact it may have on the demands of urgent care. Methods We conducted a cross-sectional survey of patients seeking care at an urgent care clinic (UCC within a large acute care safety-net urban hospital over a six-week period. Survey data included demographics, social and economic information, reasons that patients chose a UCC, previous primary care exposure, reasons for delaying care, and preventive care needs. Results A total of 1, 006 patients were randomly surveyed. Twenty-five percent of patients identified Spanish as their preferred language. Fifty-four percent of patients reported choosing the UCC due to not having to make an appointment, 51.2% because it was convenient, 43.9% because of same day test results, 42.7% because of ability to get same-day medications and 15.1% because co-payment was not mandatory. Lack of a regular physician was reported by 67.9% of patients and 57.2% lacked a regular source of care. Patients reported delaying access to care for a variety of reasons. Conclusion Despite a common belief that patients seek care in the urgent care setting primarily for economic reasons, this study suggests that patients choose the urgent care setting based largely on convenience and more timely care. This information is especially applicable to

    Wound care requires an understanding of normal wound healing, causes of delays of wound healing, and the management of wounds. Every wound must be treated as an individual with regard to cause, chronicity, location, and level of microbial contamination, as well as patient factors that affect wound healing. Knowledge of wound care products available and when negative pressure wound therapy and drain placement is appropriate can improve outcomes with wound healing. Inappropriate product use can cause delays in healing. As a wound healing progresses, management of a wound and the bandage material used must evolve. PMID:26022525

In addition,we showthat the expectation value at the present time t of a future-included theory for large T - t and large t - T corresponds to that of a future-not-included theory with a proper inner product for large t - T. Hence, the CAT...... with future explicitly present in the formalism and influencing in principle the past is not excluded phenomenologically, because the effects are argued to be very small in the present era. Furthermore, we explicitly derive the Hamiltonian for the future state via a path integral, and confirm that it...

    2010-01-01

    The US health care system has become increasingly unsustainable, threatened by poor quality and spiraling costs. Many Americans are not receiving recommended preventive care, including cancer screening tests. Passage of the Affordable Care Act in March 2010 has the potential to reverse this course by increasing access to primary care providers, extending coverage and affordability of health insurance, and instituting proven quality measures. In order for health care reform to succeed, it will require a stronger primary care workforce, a new emphasis on patient-centered care, and payment incentives that reward quality over quantity. Innovations such as patient-centered medical homes, accountable care organizations, and improved quality reporting methods are central features of a redesigned health care delivery system and will ultimately change the face of cancer care in the United States.

    In this paper we present the results of our new classification of asteroid families, upgraded by using catalog with > 500,000 asteroids. We discuss the outcome of the most recent update of the family list and of their membership. We found enough evidence to perform 9 mergers of the previously independent families. By introducing an improved method of estimation of the expected family growth in the less populous regions (e.g. at high inclination) we were able to reliably decide on rejection of one tiny group as a probable statistical fluke. Thus we reduced our current list to 115 families. We also present newly determined ages for 6 families, including complex 135 and 221, improving also our understanding of the dynamical vs. collisional families relationship. We conclude with some recommendations for the future work and for the family name problem.

  14. Including lifestyle medicine in undergraduate medical curricula

    Directory of Open Access Journals (Sweden)

    Edward Phillips

    2015-02-01

    Full Text Available Purpose: Currently, there is no model to integrate the discipline of lifestyle medicine (LM into undergraduate medical education. Furthermore, there are no guidelines, validated assessment tools, or evaluation or implementation plans in place. Background: The World Health Organization predicts that by 2020, two-thirds of disease worldwide will be the result of poor lifestyle choices. Fewer than 50% of US primary care physicians routinely provide specific guidance on nutrition, physical activity, or weight control. Methods: We are establishing a plan to integrate LM into medical school education in collaboration with the investing stakeholders, including medical school deans and students, medical curriculum developers and researchers, medical societies, governing bodies, and policy institutes. Three planning and strategy meetings are being held to address key areas of focus – with a particular interest in nutrition, physical activity, student self-care, and behavior change – to develop specific implementation guidelines and landmarks. Results: After the first two meetings, the proposed areas of focus were determined to be: 1 supporting of deans and key personnel, 2 creation of federal and state policy commitments, 3 use of assessment as a driver of LM, 4 provision of high-quality evidence-based curricular material on an easily navigated site, and 5 engaging student interest. Implementation strategies for each focus area will be addressed in an upcoming planning meeting in early 2015. Conclusion: This initiative is expected to have important public health implications by efficiently promoting the prevention and treatment of non-communicable chronic disease with a scalable and sustainable model to educate physicians in training and practice.

    Stevens, J; Crouch, M

    1995-06-01

    Many sources indicate that nurses have a negative view of work with ageing patients. Wide-spread stereotypes concerning old age no doubt exercise influences in the formation of nurses' attitudes. The research reported here suggests that nurses' negative attitudes towards the elderly are consolidated rather than dissolved in the course of their training. The reasons for this may not, in fact, lie in the nature of the gerontology components (small as they usually are) of the curriculum. Rather, the course (or the "professional socialisation" process) as a whole appears to carry messages that devalue personal care duties--contra the prestige of activities attached to all levels of medical technology. The ageing patient, often requiring much hands-on (the body) care is thus located well outside areas of work which are perceived by nurses to include clearly focused professional pathways.

    Quality assurance is a relatively recent concern but already plays a major role in health care management and provision. Quality involves the definition of a comprehensive programme tailored by realistic and effective objectives and norms that include the structured review of procedures (namely clinical audits) and the use of up-to-date protocols. The involvement and motivation of health professionals, together with an adequate internal and external communication strategy, play a key role in the planning and application of these programmes. The use of programmed assessment, based on a solid knowledge of current practice, should have practical implications, optimising procedures in order to improve the quality of care. This commitment towards quality in health care should go far beyond governmental policy and should have clear support from health professionals. PMID:11234496

Background Modern hospitals and the rational underlying care and treatment of today have their emphasis on diagnosis, cure and treatment. Consequently, aesthetics in the patient...... rooms such as a view of nature or natural light entering the room are often neglected in caring for these patients. Method A phenomenological-hermeneutic study design was applied and data was collected through multiple qualitative interviews combined with observations at a teaching hospital in Denmark......-being, relief and hope for the patients during serious illness. Therefore, these sensory impressions should be thought of as holding palliative potential and should be included as a part of caring for the seriously ill patients....

  1. Mediation and managed care.

    1998-03-01

    Managed care has not only intensified existing conflicts between patient and provider, it has, by its very nature, changed the shape and scope of the healthcare enterprise and introduced an entirely new set of disputes. The decision-making dynamics have been altered, and the cast of players has expanded. Traditionally, the therapeutic interaction took place between the physician and the patient although it occasionally included the patient's family. Whatever obligations existed, such as fidelity, confidentiality, and standard of care, they bound only those parties. Now, as the managed care organization has interposed itself between the patient and the physician, the dyad has become a triad. The power balance has shifted, and a new set of rights and responsibilities now flows between and among the players, each of whom has interests that may or may not coincide. This article argues that, because of its cost containment origins and orientation, managed care increases the likelihood that misunderstandings, disagreements and disputes will develop into full-blown conflicts. If managed care is to succeed financially and operate with integrity, it must develop techniques for managing the increasing conflicts that arise inevitably between and among the organizations, physicians, and patients. It is clear that the voice of the patient needs to be strengthened within the new complex decision-making, review, and appeal procedures. Mediation is the most appropriate method of dispute resolution for the managed care setting because it balances the disparities in power endemic to the bureaucratization of medicine and refocuses the interests of the various parties. Using bioethics consultation as a model for dispute mediation provides a set of principles and guideline tasks that can be applied effectively to managed care. PMID:9514387

    Full Text Available The benefit of intravenous recombinant tissue plasminogen activator (rt-PA therapy for very old patients with acute ischemic stroke remains unclear. The aim of this study was to elucidate the efficacy and safety of intravenous rt-PA therapy for patients over 80 years old.Of 13,521 stroke patients registered in the Fukuoka Stroke Registry in Japan from June 1999 to February 2013, 953 ischemic stroke patients who were over 80 years old, hospitalized within 3 h of onset, and not treated with endovascular therapy were included in this study. Among them, 153 patients were treated with intravenous rt-PA (0.6 mg/kg. For propensity score (PS-matched case-control analysis, 148 patients treated with rt-PA and 148 PS-matched patients without rt-PA therapy were selected by 1:1 matching with propensity for using rt-PA. Clinical outcomes were neurological improvement, good functional outcome at discharge, in-hospital mortality, and hemorrhagic complications (any intracranial hemorrhage [ICH], symptomatic ICH, and gastrointestinal bleeding.In the full cohort of 953 patients, rt-PA use was associated positively with neurological improvement and good functional outcome, and negatively with in-hospital mortality after adjustment for multiple confounding factors. In PS-matched case-control analysis, patients treated with rt-PA were still at lower risk for unfavorable clinical outcomes than non-treated patients (neurological improvement, odds ratio 2.67, 95% confidence interval 1.61-4.40; good functional outcome, odds ratio 2.23, 95% confidence interval 1.16-4.29; in-hospital mortality, odds ratio 0.30, 95% confidence interval 0.13-0.65. There was no significant association between rt-PA use and risk of hemorrhagic complications in the full and PS-matched cohorts.Intravenous rt-PA therapy was associated with improved clinical outcomes without significant increase in risk of hemorrhagic complications in very old patients (aged>80 years with acute ischemic stroke.

    Full Text Available While most complications are related to haemoglobinopathies and their treatment, it is also possible to observe substantial differences in comorbidities’ onset and seriousness which depend also to the different HPs genotypes. These differences should be carefully considered when health authorities set up and manage adequate care systems and treatments plans. We describe services organisation in Italy including the availability of multispecialty care and tools, in the HPs units participating to the HTA-THAL Multiregional Registry, with the aim to derive the impact of the services and multispecialty care availability on the management of the disease and on the patients wellbeing. The high dispersion and heterogeneity of services demonstrated, exposes the Italian system to a high risk of: a inappropriate use of economical and medical resources, b limited access to multidisciplinary care of some patients with apparent inequality among different centres, and c low patients satisfaction with the services provided. The identification of a ‘standard for HPs services’ is necessary not only at national but also at interventional level in order to implement collaborative research and the identification and networking of reference’ centres worldwide. Following the big efforts provided in the last years here there is a new challenging mission for the TIF.

    The role of technology in the cost of health care is a primary issue in current debates concerning national health care reform. The broad scope of studies for understanding technological impacts is known as technology assessment. Technology policy makers can improve their decision making by becoming more aware, and taking greater advantage, of key trends in health care technology assessment (HCTA). HCTA is the systematic evaluation of the properties, impacts, and other attributes of health care technologies, including: technical performance; clinical safety and efficacy/effectiveness; cost-effectiveness and other economic attributes; appropriate circumstances/indications for use; and social, legal, ethical, and political impacts. The main purpose of HCTA is to inform technology-related policy making in health care. Among the important trends in HCTA are: (1) proliferation of HCTA groups in the public and private sectors; (2) higher standards for scientific evidence concerning technologies; (3) methodological development in cost analyses, health-related quality of life measurement, and consolidation of available scientific evidence (e.g., meta-analysis); (4) emphasis on improved data on how well technologies work in routine practice and for traditionally under-represented patient groups; (5) development of priority-setting methods; (6) greater reliance on medical informatics to support and disseminate HCTA findings.

  6. The challenge of supporting care for dementia in primary care

    Full Text Available Malaz Boustani1,2,3, Cathy Schubert3, Youcef Sennour31Indiana University Center for Aging Research; 2Regenstrief Institute; 3Department of Medicine, Indiana University School of Medicine, Indianapolis, Indiana, USAAbstract: Most patients with dementia receive care within primary care systems and have challenging medical and psychiatric issues. Their dementia related symptoms are often not recognized by the primary care system; they suffer from multiple chronic medical conditions; receive numerous psychotropic medications including anticholinergics; and display clinically relevant behavioral and psychological symptoms. Improving the care for such vulnerable patients demands supporting the primary care system with various resources, including dementia care managers, access to and coordination with interdisciplinary dementia specialists, and a feasible dementia screening and diagnosis process. Understanding primary care clinics as a complex adaptive system may enhance our capacity to deliver a flexible supportive process using the above crucial resources to adequately assess and effectively manage patients with dementia. Such a complex adaptive system process would have the best probability of surviving the unknowable future challenges that will face the primary care system.

    Adolescent girls face unique challenges in health care utilization, which can result in unmet needs. We sought to describe settings of usual care and primary care use, and to identify predictors of foregone care and experience of confidential care in a primarily racial/ethnic minority low-income sample. We conducted an anonymous computer-assisted self-administered survey of 9th-12th grade girls (n=819) in three Bronx public high schools, the majority of whom were Hispanic (69.8%) and Black (21.4%). Most (80%) reported having a usual source of care. Of these, 77.2% had a regular doctor. Those least likely to have a usual source of care were non-U.S. born girls (73.1% vs. 83.1%) and less acculturated girls. Predictors of foregone care in the last year include being sexually active, poor family social support, and low self esteem. Predictors of access to confidential care at last visit were age, self-efficacy for confidential care, having a regular doctor, setting of care, and having had a recent physical exam. Many urban adolescent girls, especially non-U.S. born girls, lack a usual source of care and regular health care provider. Continued attention to reducing both financial and non-financial barriers to care is required to ensure access to and quality of care for diverse populations. PMID:17242529

    Because neurodegenerative dementias are progressive and ultimately fatal, a palliative approach focusing on comfort, quality of life, and family support can have benefits for patients, families, and the health system. Elements of a palliative approach include discussion of prognosis and goals of care, completion of advance directives, and a thoughtful approach to common complications of advanced dementia. Physicians caring for patients with dementia should formulate a plan for end-of-life care in partnership with patients, families, and caregivers, and be prepared to manage common symptoms at the end of life in dementia, including pain and delirium.

    Objective To evaluate the safety of selectively early administration of oral antiplatelet therapy within 1 hour after recombinant tissue type plasminogen activator (rt-PA) treatment in patients with acute ischemic stroke. Methods A total of 112 acute ischemic stroke patients with relatively low hemorrhagic transformation (HT) risk according to multimode imaging and hemorrhage after thrombolysis (HAT) score were selected for this clinical trial from Department of Neurology of The Third Afifliated Hospital of Third Military Medical University, from January 2011 to April 2014. Sixty-six patients were treated with oral 100 mg aspirin and 75 mg clopidogrel within 1 hour after the intravenous rt-PA administration with the informed consent from the patients or their legal representatives. In the other 46 patients, oral antiplatelet therapy started 24 hours after rt-PA treatment according to the will of the patients or their family, who preferred to follow the current guidelines. The primary safety endpoint was the reocclusion in 1 d after the thrombolysis, HT in 3 d, the score of National Institutes of Health Stroke Scale (NIHSS) in 7 d, and the death of the patients. Results There was no significant difference in the baseline (including gender, age, level of blood pressure, blood glucose and cholesterin before thrombolysis, the history of transient ischemic attack or cardiac valvular disease, etc.) between two groups. Importantly, no signiifcant difference was found in HT (7.6%vs 6.5%,P=1.000), while the number of symptomatic intracerebral hemorrhage and death in both groups were zero. We even found decreasing tendency of NIHSS score at 7 d after the thrombolysis (NIHSS=6vs NIHSS=7,P=0.143) and the frequency of reocclusion (4.5%vs 15.2 %,P=0.107) in early antiplatelet administration group was reduced although no signiifcance was achieved. Conclusion Administration of oral antiplatelet therapy within 1 hour after patients with acute ischemic stroke treated with rt-PA does

    Science.gov (United States)

    2016-06-01

    In the weeks after birth, postpartum care often is fragmented among maternal and pediatric health care providers, and communication between inpatient and outpatient settings is inconsistent. To optimize postpartum care, anticipatory guidance should begin during pregnancy. During antenatal care, it is recommended that the patient and her obstetrician-gynecologist or other obstetric care provider formulate a postpartum care plan and identify the health care professionals who will comprise the postpartum care team for the woman and her infant. Ideally, during the postpartum period, a single health care practice assumes responsibility for coordinating the woman's care. At discharge from maternity care, the woman should receive contact information for her postpartum care team and written instructions regarding the timing of follow-up postpartum care. It is recommended that all women undergo a comprehensive postpartum visit within the first 6 weeks after birth. This visit should include a full assessment of physical, social, and psychological well-being. Systems should be implemented to ensure each woman can receive her desired form of contraception during the comprehensive postpartum visit, if not done earlier. At the conclusion of the postpartum visit, the woman and her obstetrician-gynecologist or other obstetric care provider should determine who will assume primary responsibility for her ongoing care. If responsibility is transferred to another primary care provider, the obstetrician-gynecologist or other obstetric care provider is responsible for ensuring that there is communication with the primary care provider so that he or she can understand the implications of any pregnancy complications for the woman's future health and maintain continuity of care.

    Adequate dental and oral hygiene may become a challenge for all users and especially for elderly people and young children because of their limited motor skills. The same holds true for patients undergoing/recovering from chemo-/radiotherapy with accompanying sensitive mucosal conditions. Poor dental hygiene can result in tooth decay, gingivitis, periodontitis, tooth loss, bad breath (halitosis), fungal infection and gum diseases. The use of a toothbrush is the most important measure for oral hygiene. Toothbrushes with soft bristles operated carefully by hand or via an electric device help to remove plaque and to avoid mucosal trauma. A handlebar with a grip cover can be helpful for manually disabled patients or for those with reduced motor skills. In case of oral hygiene at the bedside or of patients during/after chemo-/radiotherapy a gauze pad can be helpful for gently cleaning the teeth, gums and tongue. The use of fluoride toothpaste is imperative for the daily oral hygiene. Detergents such as sodium lauryl sulphate improve the cleaning action but may also dehydrate and irritate the mucous membrane. The use of products containing detergents and flavouring agents (peppermint, menthol, cinnamon) should therefore be avoided by bedridden patients or those with dry mouth and sensitive mucosa. Aids for suitable interdental cleaning, such as dental floss, interdental brushes or dental sticks, are often complicated to operate. Their correct use should be instructed by healthcare professionals. To support dental care, additional fluoridation with a fluoride gel or rinse can be useful. Products further containing antiseptics such as chlorhexidine or triclosan reduce the quantity of bacteria in the mouth. For patients undergoing or having undergone radio-/chemotherapy, a mouthwash that concomitantly moisturizes the oral mucosa is advisable. PMID:21325845

    Full Text Available Abstract Background Chronic disease management requires input from multiple health professionals, both specialist and primary care providers. This study sought to assess the impact of co-ordinated multidisciplinary care in primary care, represented by the delivery of formal care planning by primary care teams or shared across primary-secondary teams, on outcomes in stroke, relative to usual care. Methods A Systematic review of Medline, EMBASE, CINAHL (all 1990–2006, Cochrane Library (Issue 1 2006, and grey literature from web based searching of web sites listed in the CCOHA Health Technology Assessment List Analysis used narrative analysis of findings of randomised and non-randomised trials, and observational and qualitative studies of patients with completed stroke in the primary care setting where care planning was undertaken by 1 a multi-disciplinary primary care team or 2 through shared care by primary and secondary providers. Results One thousand and forty-five citations were retrieved. Eighteen papers were included for analysis. Most care planning took part in the context of multidisciplinary team care based in hospitals with outreach to community patients. Mortality rates are not impacted by multidisciplinary care planning. Functional outcomes of the studies were inconsistent. It is uncertain whether the active engagement of GPs and other primary care professionals in the multidisciplinary care planning contributed to the outcomes in the studies showing a positive effect. There may be process benefits from multidisciplinary care planning that includes primary care professionals and GPs. Few studies actually described the tasks and roles GPs fulfilled and whether this matched what was presumed to be provided. Conclusion While multidisciplinary care planning may not unequivocally improve the care of patients with completed stroke, there may be process benefits such as improved task allocation between providers. Further study on the impact

    Focusing on the population exposed to radioactivity released from a nuclear power plant, the paper gives an overview of medical strategies in emergency care, steps in medical care, and clinical procedures including decontamination and oral administration of iodine-131. Strategies for evacuation are presented depending on predicted exposure doses to the whole body and thyroid gland. Medical care consists of three steps. When the thyroid gland is supposed to be exposed to 5 - 50 rem or more, the oral administration of iodine-131 is recommended. (Namekawa, K.)

    2007-07-01

    Full Text Available Music has been used therapeutically for many centuries, and numerous studies have researched the curative and preventative powers of music in several diseases. Music, as a therapy was shown to have positive effects in child care, such as in premature infants, children in emergency care, children receiving surgery, children in oncology departments and handicapped children. The aim of this review was to study the therapeutic effects of music in child care at hospital. The method οf this study included bibliography research from both the review and the research internatio nal literature, which was referred to the therapeutic effects of music in Children's Hospital. Results: Most studies focus on the beneficial effects of music to child. The results of the study showed that music is widely used to enhance well‐being and appears to exert direct effects to child, which are mainly related to physiology and psychology, including changes in the vital signs, reductions in anxiety and pain, distraction of attention from unpleasant sensations and better communication with the environment at hospital. Furthermore, music exerts indirect effects to child since is able to cause positive modifications in nurses' behaviour and conduces to better performance in their duties. Conclusions: Music consists a low-cost "therapeutic instrument" for nurses to apply to child-patient and is found to be effective in producing positive outcomes. The nurses' knowledge of music therapy need to be improved and the therapeutic impact of music must be a result from systematic professional application.

  9. Managed care opportunities for improving asthma care.

    Campbell, Jonathan D

    2011-04-01

    Uncontrolled asthma is an enormous burden in terms of the propensity to reach asthma control in the future, direct and indirect costs, and health-related quality of life. The complex pathophysiology, treatment, and triggers of asthma warrant a unified, yet targeted, approach to care. No single factor is fully responsible for poor control. Complicating the problem of asthma control is adherence to long-term controller medications. The National Asthma Education and Prevention Program (NAEPP) established several key points for asthma control, and developed classifications for asthma control and recommended actions for treatment. All parties involved in the management of asthma, including physicians, pharmacists, nurses, patients, family members, and insurance companies, need to be aware of the NAEPP guidelines. To determine if the goals of asthma therapy are being met, assessment of asthma outcomes is necessary. Unfortunately, some measures may get overlooked, and patient-reported outcomes (as assessed by the validated control instruments) are not often collected during routine examinations. The Healthcare Effectiveness Data and Information Set measure for asthma may be used to quantify asthma care, but there is evidence that it does not fully capture the goals of asthma management. Most well-designed, education-based interventions are considered good value for money, but it can be difficult to put into practice such policy interventions. An optimal managed care plan will adhere to known evidence-based guidelines, can measure outcomes, is targeted to the patient's risk and impairment, and can adapt to changes in our understanding of asthma and its treatment.

    1999-08-01

    Meeting the health care needs of the spinal cord-injured patient is an immense challenge for the acute care multidisciplinary team. The critical care nurse clinician, as well as other members of the team, needs to maintain a comprehensive knowledge base to provide the care management that is essential to the care of the spinal cord-injured patient. With the active participation of the patient and family in care delivery decisions, the health care professionals can help to meet the psychosocial and physical needs of the patient/family unit. This article provides an evidence-based, comprehensive review of the needs of the spinal cord-injured patient in the acute care setting including optimal patient outcomes, methods to prevent complications, and a plan that provides an expeditious transition to rehabilitation.

    Abstract Depression is one of the more common diagnoses encountered in primary care, and primary care in turn provides the majority of care for patients with depression. Many approaches have been tried in efforts to improve the outcomes of depression management. This article outlines the partnership between the University of Washington (UW) Neighborhood Clinics and the UW Department of Psychiatry in implementing a collaborative care approach to integrating the management of anxiety and depression in the ambulatory primary care setting. This program was built on the chronic care model, which utilizes a team approach to caring for the patient. In addition to the patient and the primary care provider (PCP), the team included a medical social worker (MSW) as care manager and a psychiatrist as team consultant. The MSW would manage a registry of patients with depression at a clinic with several PCPs, contacting the patients on a regular basis to assess their status, and consulting with the psychiatrist on a weekly basis to discuss patients who were not achieving the goals of care. Any recommendation (eg, a change in medication dose or class) made by the psychiatrist was communicated to the PCP, who in turn would work with the patient on the new recommendation. This collaborative care approach resulted in a significant improvement in the number of patients who achieved care plan goals. The authors believe this is an effective method for health systems to integrate mental health services into primary care. (Population Health Management 2016;19:81–87) PMID:26348355

    The recombinant tissue plasminogen activator alteplase (rt-PA) is the most effective therapeutic drug used in intravenous thrombolysis for patients with acute ischaemic stroke presenting within 4.5h after symptom onset. Nevertheless, intravenous thrombolysis is accompanied with hemorrhagic transformation (HT), increased risk of symptomatic intracranial haemorrhage (sICH), poor prognosis and even deaths. Therefore, study on inlfuential factors on treatment and prognosis and improvement of efifcacy and safety of intravenous thrombolysis has important signiifcance for prognosis of patients with acute ischemic stroke.%重组组织型纤溶酶原激活剂(recombinant tissue plasminogen activator alteplase,rt-PA)是目前急性缺血性卒中时间窗内静脉溶栓最有效的治疗药物,然而,静脉溶栓也伴随着出血转化、症状性颅内出血风险的增加,导致患者预后不良,甚至死亡。因此,研究静脉溶栓治疗及预后的影响因素,提高静脉溶栓治疗的有效性及安全性,对急性缺血性卒中患者的预后有着重大意义。

    Full Text Available Marked regional differences in HIV-related clinical outcomes exist across Europe. Models of outpatient HIV care, including HIV testing, linkage and retention for positive persons, also differ across the continent, including examples of sub-optimal care. Even in settings with reasonably good outcomes, existing models are scrutinized for simplification and/or reduced cost. Outpatient HIV care models across Europe may be centralized to specialized clinics only, primarily handled by general practitioners (GP, or a mixture of the two, depending on the setting. Key factors explaining this diversity include differences in health policy, health insurance structures, case load and the prevalence of HIV-related morbidity. In clinical stable populations, the current trend is to gradually extend intervals between HIV-specific visits in a shared care model with GPs. A similar shared-model approach with community clinics for injecting drug-dependent persons is also being implemented. Shared care models require oversight to ensure that primary responsibility is defined for the persons overall health situation, for screening of co-morbidities, defining indication to treat comorbidities, prescription of non-HIV medicines, etc. Intelligent bioinformatics platforms (i.e. generation of alerts if course of care deviates from a prior defined normality are being developed to assist in providing this oversight and to provide measure of quality. Although consensus exists to assess basic quality indicators of care, a comprehensive set of harmonized indicators are urgently needed to define best practise standards via benchmarking. Such a tool will be central to guide ongoing discussions on restructuring of models, as quality of care should not be compromised in this process.

    Care of critically injured patients has evolved over the 50 years since Shoemaker established one of the first trauma units at Cook County Hospital in 1962. Modern trauma intensive care units offer a high nurse-to-patient ratio, physicians and midlevel providers who manage the patients, and technologically advanced monitors and therapeutic devices designed to optimize the care of patients. This article describes advances that have transformed trauma critical care, including bedside ultrasonography, novel patient monitoring techniques, extracorporeal support, and negative pressure dressings. It also discusses how to evaluate the safety and efficacy of future advances in trauma critical care. PMID:22850154

    Wound care is an important step in promoting wound healing, but it may cause wound care pain. This article aims to explore factors influencing wound care pain and the effectiveness of various interventions to alleviate it. Five major factors that influence wound care pain include inappropriate dressing change techniques, inflammation response, emotion, cognition, and social-cultural factors. Nurses should apply appropriate dressings and dressing change techniques to relieve wound care pain. Music therapy and aromatherapy can alleviate wound pain after dressing change. But distraction techniques should be used in conjunction with consideration of the needs of the individual subject. PMID:17554674

    An efficient primary care is of particular importance for any countries' health care system. Many differences exist on how distinctive countries try to obtain the goal of an efficient, cost-effective primary care for its population. In this article we conducted a selective literature review, which includes both scientific and socio-political publications. The findings are complemented with the experience of a Spanish physician from Seville in her last year of training in family medicine, who completed a four months long rotation in the German health care system. We highlighted different features by comparing both countries, including their health care expenditure, the relation between primary and secondary care, the organization in the academic field and the training of future primary care physicians. It is clear that primary care in both countries plays a central role, have to deal with shortcomings, and in some points one system can learn from the other. PMID:26363955

    The purpose of the study was to evaluate the role of an online resource for dying children, their family members, and health care providers from the perspective of pediatric palliative care experts. Semistructured interviews with 12 leaders in pediatric palliative care in North America were conducted, exploring their perceptions and attitudes towards various aspects of Web-based resources for dying children and their care providers. Informants felt that an online resource may allow for a different form of expression, a connection between people undergoing a rare event, and an increase in education and support. Major challenges, such as accessibility, monitoring, and remaining current, would be ongoing. Other key themes included access, information, and anonymity. The data suggest that developing Web-based resources for dying young patients and their families may have merit. Should this take place, a feasibility study will be necessary to further determine the value of such a Web site for these vulnerable populations. PMID:18459596

    The Australian Government is wise to examine other health care systems as it strives to improve the quality of care and address rising costs to both governments and individuals. Focus is currently on the United Kingdom, whose National Health Service (NHS) stands out as one that delivers good care at a reasonable price to all who need it. The Australian and UK systems have many similarities: universal access, tax payer support, no or low cost at point of delivery, and good population health outcomes. They also face similar pressures on services from aging, increasingly unwell yet expectant populations.However, there are also differences, largely in the way that health care is funded, organised and delivered. The NHS is a huge system for 60 million people in four home countries with diverging policies. Within England, the system is managed through 10 strategic health authorities, each responsible for about 5 million people and having the right to interpret national policy. Population based health care, including tertiary care, is funded locally via primary care trusts. PMID:19283244

    Epilepsy care in Ireland is shared between primary, secondary and tertiary care services with the General Practitioner (GP) managing the process. Barriers to effective epilepsy care in Irish general practice remain undocumented although sub-optimal and fragmented services are frequently anecdotally reported. This survey of Irish GPs reports on such barriers to epilepsy care and on the Information & Communication Technology (ICT) issues potentially relevant to the use of an epilepsy specific Electronic Patient Record (EPR). The response rate was 247\\/700 (35.3%). Respondents supported the concept of shared care for epilepsy 237 (96%) however they were very dissatisfied with existing neurology services, including pathways of referral 207 (84%) and access to specialist neurology advice and investigations 232 (94%). They reported that neurology services and investigations may be accessed more expeditiously by patients with private health insurance than those without 178 (72%). Consequently many patients are referred to the emergency department for assessment and treatment 180 (73%). A deficit in epilepsy care expertise among GPs was acknowledged 86 (35%). While computerisation of GP practices appears widespread 230 (93%), just over half the respondents utilise available electronic functionalities specific to chronic disease management. GP specific electronic systems infrequently link or communicate with external electronic sources 133 (54%). While the current pathways of care for epilepsy in Ireland appear fragmented and inadequate, further investigations to determine the quality and cost effectiveness of the current service are required.

    2016-07-01

    Burnout syndrome (BOS) occurs in all types of health care professionals and is especially common in individuals who care for critically ill patients. The development of BOS is related to an imbalance of personal characteristics of the employee and work-related issues or other organizational factors. BOS is associated with many deleterious consequences, including increased rates of job turnover, reduced patient satisfaction, and decreased quality of care. BOS also directly affects the mental health and physical well-being of the many critical care physicians, nurses, and other health care professionals who practice worldwide. Until recently, BOS and other psychological disorders in critical care health care professionals remained relatively unrecognized. To raise awareness of BOS, the Critical Care Societies Collaborative (CCSC) developed this call to action. The present article reviews the diagnostic criteria, prevalence, causative factors, and consequences of BOS. It also discusses potential interventions that may be used to prevent and treat BOS. Finally, we urge multiple stakeholders to help mitigate the development of BOS in critical care health care professionals and diminish the harmful consequences of BOS, both for critical care health care professionals and for patients.

    All good intensive care requires attention to detail of the routine elements of care. These include staffing and monitoring, drug prescription and administration, feeding and fluid balance, analgesia and sedation, organ support and reducing the risk of healthcare-associated infection. Doing this well requires an understanding of the relevant physiology and an awareness of the limited evidence base. Detailed protocols and implementation checklist are valuable in ensuring that these minimum standards are met. However, peri-operative care is not all predictable and amenable to protocolization. This is especially true following separation of conjoined twins. Despite the sophisticated imaging and multi-disciplinary planning that precede elective separation, the acute physiological changes in each twin cannot always be predicted reliably. In this article, we review briefly each element of peri-operative care and how this might vary in conjoined twins. PMID:26382268

    Conjoined twinning is one of the most uncommon congenital anomalies. Maintenance in an intensive care setting during this time allows for close monitoring, stabilisation, and nutritional supplementation of the infants as necessary to optimise preoperative growth and development. The birth of conjoined twins is a very difficult and dramatic moment for parents. It is also a very difficult situation for the team of physicians, nurses and other required hospital staff to carry out treatment and care of these specific developmental anomalies. The diagnostics and treatment in this extraordinary situation requires close cooperation of the multidisciplinary medical team, which includes their personal experience and medical knowledge, with a team of intensive care unit nurses. This report presents the rules in cease of conjoined twins during their intensive care unit stay with special reference to the proceedings before and after complete separation. PMID:24858974

    The terms palliative and end of life care are often used interchangeably and healthcare practitioners may perceive that palliative care is only appropriate during the terminal stages of an illness. This article, the first of two parts, provides healthcare practitioners with an overview of the concept of palliative care. It explains how this can be differentiated from end of life care and how it should be commenced in a timely manner, so that people who are living with dementia can contribute to the planning of their future care and death. The policies and tools used in the provision of palliative and end of life care are discussed, including advance care planning and The Gold Standards Framework. The article is framed in a care home context; there is little research about how to optimise palliative care for people living with dementia in care homes. The second part of this article will discuss end of life care and the best practices for providing end of life care, including nutrition and hydration, oral hygiene, pain management and spiritual care.

    Partial and total maternal and child health care costs were estimated. The study was developed in a Primary Care Health Clinic (PCHC) and a General Hospital (GH) of a social security health care system. Maternal and child health care services, type of activity and frequency utilization during 1995, were defined; cost examination was done separately for the PCHC and the GH. Estimation of fixed cost included departmentalization, determination of inputs, costs, basic services disbursements, and weighing. These data were related to depreciation, labor period and productivity. Estimation of variable costs required the participation of field experts; costs corresponded to those registered in billing records. The fixed cost plus the variable cost determined the unit cost, which multiplied by the of frequency of utilization generated the prenatal care, labor and delivery care, and postnatal care cost. The sum of these three equaled the maternal and child health care cost. The prenatal care cost was $1,205.33, the labor and delivery care cost was $3,313.98, and the postnatal care was $559.91. The total cost of the maternal and child health care corresponded to $5,079.22. Cost information is valuable for the health care personnel for health care planning activities. PMID:9528219

  20. Strengthening of primary health care: Key to deliver inclusive health care

    Full Text Available Inequity and poverty are the root causes of ill health. Access to quality health services on an affordable and equitable basis in many parts of the country remains an unfulfilled aspiration. Disparity in health care is interpreted as compromise in ′Right to Life.′ It is imperative to define ′essential health care,′ which should be made available to all citizens to facilitate inclusivity in health care. The suggested methods for this include optimal utilization of public resources and increasing public spending on health care. Capacity building through training, especially training of paramedical personnel, is proposed as an essential ingredient, to reduce cost, especially in tertiary care. Another aspect which is considered very important is improvement in delivery system of health care. Increasing the role of ′family physician′ in health care delivery system will improve preventive care and reduce cost of tertiary care. These observations underlie the relevance and role of Primary health care as a key to deliver inclusive health care. The advantages of a primary health care model for health service delivery are greater access to needed services; better quality of care; a greater focus on prevention; early management of health problems; and cumulative improvements in health and lower morbidity as a result of primary health care delivery.

    Full Text Available Abstract Background Older people living in care homes in England have complex health needs due to a range of medical conditions, mental health needs and frailty. Despite an increasing policy expectation that professionals should operate in an integrated way across organisational boundaries, there is a lack of understanding between care homes and the National Health Service (NHS about how the two sectors should work together, meaning that residents can experience a poor "fit" between their needs, and services they can access. This paper describes a survey to establish the current extent of integrated working that exists between care homes and primary and community health and social services. Methods A self-completion, online questionnaire was designed by the research team. Items on the different dimensions of integration (funding, administrative, organisational, service delivery, clinical care were included. The survey was sent to a random sample of residential care homes with more than 25 beds (n = 621 in England in 2009. Responses were analysed using quantitative and qualitative methods. Results The survey achieved an overall response rate of 15.8%. Most care homes (78.7% worked with more than one general practice. Respondents indicated that a mean of 14.1 professionals/ services (other than GPs had visited the care homes in the last six months (SD 5.11, median 14; a mean of .39 (SD.163 professionals/services per bed. The most frequent services visiting were district nursing, chiropody and community psychiatric nurses. Many (60% managers considered that they worked with the NHS in an integrated way, including sharing documents, engaging in integrated care planning and joint learning and training. However, some care home managers cited working practices dictated by NHS methods of service delivery and priorities for care, rather than those of the care home or residents, a lack of willingness by NHS professionals to share information, and low

  2. What is Good Quality of Health Care?

    Full Text Available A diversity of definitions of quality exists, that frequently contain aspects of complexity, relativity and subjectivity. This paper provides an overview of key components in the quality debate within health care, including different perspectives and dimensions of the quality of care. Definitions of the quality of health care reflect the characteristics of health services, and are useful for measurements and quality improvement. Over time the patient perspective of quality has gotten increasing weight, and in quality improvement there has been a shift from individual responsibility for doctors and health care personnel to systems thinking. We argue that the quality approach in health care should be more standardized and that health care-specific definitions of quality should be used when the relationship between physician professionalism and quality is investigated.Keywords: quality, health care, systems thinking, patient perspective, outcome, indicator, measurement, improvement.

    Background Unregulated care aides provide up to 80 % of direct resident care in nursing homes. They have little formal training, manage high workloads, frequently experience responsive behaviours from residents, and are at high risk for burnout. This affects quality of resident care, including quality of oral health care. Poor quality of oral health care in nursing homes has severe consequences for residents and the health care system. Improving quality of oral health care requires tailoring ...

    2012-01-01

    Full Text Available Research focusing on the introduction of daily mouth care programs for dependent older adults in long-term care has met with limited success. There is a need for greater awareness about the importance of oral health, more education for those providing oral care, and organizational structures that provide policy and administrative support for daily mouth care. The purpose of this paper is to describe the establishment of an oral care action plan for long-term care using an interdisciplinary collaborative approach. Methods. Elements of a program planning cycle that includes assessment, planning, implementation, and evaluation guided this work and are described in this paper. Findings associated with assessment and planning are detailed. Assessment involved exploration of internal and external factors influencing oral care in long-term care and included document review, focus groups and one-on-one interviews with end-users. The planning phase brought care providers, stakeholders, and researchers together to design a set of actions to integrate oral care into the organizational policy and practice of the research settings. Findings. The establishment of a meaningful and productive collaboration was beneficial for developing realistic goals, understanding context and institutional culture, creating actions suitable and applicable for end-users, and laying a foundation for broader networking with relevant stakeholders and health policy makers.

  5. Perioperative Care of the Transgender Patient.

    2016-02-01

    Transgender patients are individuals whose gender identity is not related to their biological sex. Assuming a new gender identity that does not conform to societal norms often results in discrimination and barriers to health care. The exact number of transgender patients is unknown; however, these patients are increasingly seen in health care. Transgender individuals may experience provider-generated discrimination in health care facilities, including refusal of service, disrespect, and abuse, which contribute to depression and low self-esteem. Transgender therapies include mental health counseling for depression and low self-esteem, hormone therapy, and sex reassignment surgery. Health care professionals require cultural competence, an understanding of the different forms of patient identification, and adaptive approaches to care for transgender patients. VA (Veterans Affairs) hospitals provide a model for the care for transgender patients and staff. PMID:26849981

    Full Text Available BACKGROUND: Caring for patients with multimorbidity is common for generalists, although such patients are often excluded from clinical trials, and thus such trials lack of generalizability. Data on the association between multimorbidity and preventive care are limited. We aimed to assess whether comorbidity number, severity and type were associated with preventive care among patients receiving care in Swiss University primary care settings. METHODS: We examined a retrospective cohort composed of a random sample of 1,002 patients aged 50-80 years attending four Swiss university primary care settings. Multimorbidity was defined according to the literature and the Charlson index. We assessed the quality of preventive care and cardiovascular preventive care with RAND's Quality Assessment Tool indicators. Aggregate scores of quality of provided care were calculated by taking into account the number of eligible patients for each indicator. RESULTS: Participants (mean age 63.5 years, 44% women had a mean of 2.6 (SD 1.9 comorbidities and 67.5% had 2 or more comorbidities. The mean Charlson index was 1.8 (SD 1.9. Overall, participants received 69% of recommended preventive care and 84% of cardiovascular preventive care. Quality of care was not associated with higher numbers of comorbidities, both for preventive care and for cardiovascular preventive care. Results were similar in analyses using the Charlson index and after adjusting for age, gender, occupation, center and number of visits. Some patients may receive less preventive care including those with dementia (47% and those with schizophrenia (35%. CONCLUSIONS: In Swiss university primary care settings, two thirds of patients had 2 or more comorbidities. The receipt of preventive and cardiovascular preventive care was not affected by comorbidity count or severity, although patients with certain comorbidities may receive lower levels of preventive care.

    Mechanic, David; Olfson, Mark

    2016-03-28

    Provisions of the Affordable Care Act provide unprecedented opportunities for expanded access to behavioral health care and for redesigning the provision of services. Key to these reforms is establishing mental and substance abuse care as essential coverage, extending Medicaid eligibility and insurance parity, and protecting insurance coverage for persons with preexisting conditions and disabilities. Many provisions, including Accountable Care Organizations, health homes, and other structures, provide incentives for integrating primary care and behavioral health services and coordinating the range of services often required by persons with severe and persistent mental health conditions. Careful research and experience are required to establish the services most appropriate for primary care and effective linkage to specialty mental health services. Research providing guidance on present evidence and uncertainties is reviewed. Success in redesign will follow progress building on collaborative care and other evidence-based practices, reshaping professional incentives and practices, and reinvigorating the behavioral health workforce.

    Differences in religious faith-based viewpoints (controversies) on the sanctity of human life, acceptable behaviour, health-care technologies and health-care services contribute to the widespread variations in health care worldwide. Faith-linked controversies include family planning, child protection (especially child marriage, female genital mutilation, and immunisation), stigma and harm reduction, violence against women, sexual and reproductive health and HIV, gender, end-of-life issues, and faith activities including prayer. Buddhism, Christianity, Hinduism, Islam, Judaism, and traditional beliefs have similarities and differences in their viewpoints. Improved understanding by health-care providers of the heterogeneity of viewpoints, both within and between faiths, and their effect on health care is important for clinical medicine, public-health programmes, and health-care policy. Increased appreciation in faith leaders of the effect of their teachings on health care is also crucial. This Series paper outlines some faith-related controversies, describes how they influence health-care provision and uptake, and identifies opportunities for research and increased interaction between faith leaders and health-care providers to improve health care.

    Full Text Available Background: Caring forms the core of nursing and midwifery. Despite caring being an important emotional aspect of midwifery and nursing, there are general public complaints about uncaring behaviour in midwifery. Therefore, there is a need to explore caring from midwives’ point of view with the hope of identifying solutions and recommendations for midwifery practice. Furthermore, the study aimed to stimulate debate and discussion about the caring behaviour of midwives.Objective: To explore caring during clinical practice as perceived and experienced by midwives.Method: The study was contextual, exploratory and qualitative. The participants were midwives working in state and private hospitals in Tshwane,South Africa where BTech II and III midwifery learners were allocated for work integrated learning (WIL. Data collection was carried out through self-report using a questionnaire and focus group. Questionnaires were distributed to 40 midwives at private and state hospitals in Tshwane. This was followed by two focus group sessions to ensure that data is enriched. The hermeneutic interpretive approach was used to analyse data, and analysis continued until saturation.Results: Themes of caring and uncaring related to patient care and midwives emerged. Thefindings illustrated that the midwives had excellent theoretical knowledge of caring, but someof them did not display caring behaviour during clinical practice.Conclusion: Some of the midwives did not display caring behaviour. Implication for practicewas provided based on the research findings. Recommendations included measures of improving caring behaviours during midwifery practice.

    Wrestling is a popular high school and college sport with an injury and illness rate second only to football. It is important that the physician providing medical care for wrestlers be familiar with the unique characteristics of wrestling and the associated common injuries and medical problems. Common orthopedic injuries include shoulder, elbow, and finger dislocation; prepatellar bursitis; knee medial collateral ligament sprains; and cervical strains. Skin infections are the most common cause of missed mat time for wrestlers. Physicians need to be able to identify and treat these infections, and know the rules regarding return to wrestling once an infection has been identified. Other conditions that are common include auricular hematomas, epistaxis, and brow lacerations. Physicians also need to be familiar with the medical issues involved with rapid weight loss and weight cycling, and understand the high school and college weight certification rules. PMID:26359843

    As greater numbers of the elderly use health services, and as health care costs climb, effective financial tracking is essential. Cost management in health care can benefit if costs are linked to the care activities where they are incurred. Activity-based costing (ABC) provides a useful approach. The framework aligns costs (inputs), through activities (process), to outputs and outcomes. It allocates costs based on client care needs rather than management structure. The ABC framework was tested in a residential care facility and in supportive housing apartments. The results demonstrate the feasibility and advantages of ABC for long term care agencies, including community-based care. PMID:10339203

    Advances in medical science and technology, together with improved medical and nursing care, are continuously improving health outcomes in chronic illness, including epilepsy. The consequent increasing diagnostic and therapeutic complexity is placing a burgeoning strain on health care systems. In response, an international move to transform chronic disease management (CDM) aims to optimize the quality and safety of care while containing health care costs. CDM models recommend: integration of care across organizational boundaries that is supported with information and communication technology; patient self-management; and guideline implementation to promote standardized care. Evidence of the effectiveness of CDM models in epilepsy care is presented in this review article.

    Though people are generally averse to change, change and innovation are critically important in respiratory care to maintain scientific and clinical progress. This paper reviews the issue of change in respiratory care. I summarize several available models of organizational and personal change (ie, those of Kotter and of Silversin and Kornacki, and the Intentional Change Theory of Boyatzis), review the characteristics of change-avid respiratory therapy departments, offer an example of a change effort in respiratory care (implementation of respiratory care protocols) and then analyze this change effort as it took place at one institution, the Cleveland Clinic, using these models. Finally, I present the results of an analysis of change-avid respiratory therapy departments and offer some suggestions regarding change management for the profession and for individual respiratory care clinicians. Common features of theories of organizational change include developing a sense of urgency, overcoming resistance, developing a guiding coalition, and involving key stakeholders early. With the understanding that change efforts may seem unduly "clean" and orderly in retrospect, the models help explain the sustainable success of efforts to implement the Respiratory Therapy Consult Service at the Cleveland Clinic. By implication, these models offer value in planning change efforts prospectively. Further analysis of features of change-avid respiratory therapy departments indicates 11 highly desired features, of which four that especially characterize change-avid departments include: having an up-to-date leadership team; employee involvement in change; celebrating wins; and an overall sense of progressiveness in the department. This analysis suggests that understanding and embracing change is important. To anchor change in our profession, greater attention should be given to developing a pipeline of respiratory care clinicians who, by virtue of their advanced training, have the skills
