    Patients who have recently undergone total knee arthroplasty are at high risk of developing deep venous thrombosis (DVT) in the calf. The clinical diagnosis of DVT is difficult in these patients owing to recent operation. A combination of compression ultrasonography (US) and colour flow imaging was used as a screening method of asymptomatic DVT in 51 patients who had undergone total knee replacement surgery. Both limbs were examined by US from the common femoral vein to the ankle approximately 7 days after operation and the results were compared with bilateral venography. 12 patients (24%) developed infrapopliteal DVT on the operated side, in two cases the thrombosis extended to the lower part of popliteal vein. One patient had bilateral thrombosis. US showed sensitivity of 77%, specificity of 96% and overall accuracy of 93%. US seems to be a useful screening method for DVT after knee replacement operation.

  2. The use of indium-111 labeled platelet scanning for the detection of asymptomatic deep venous thrombosis in a high risk population

    International Nuclear Information System (INIS)

    Five hundred indium-111 labeled platelet imaging studies (387 donor and 113 autologous) were performed postoperatively in 473 patients who had undergone total hip replacement, total knee replacement, or internal fixation of a hip fracture to detect occult deep venous thrombosis. All patients had been anticoagulated prophylactically with aspirin, warfarin sodium (Coumadin), or dextran. Thirty-four possible cases of proximal deep venous thrombosis were identified in 28 asymptomatic patients. To verify the scan results, 31 venograms were performed in 25 patients (three refused). In 21 of 31 cases, totally occlusive thrombi were detected; in 5 cases, partially occlusive thrombi were detected; in 5 cases, no thrombus was seen. No patient who had a negative scan nor any patient who had a verified positive scan (and received appropriate heparin therapy) subsequently developed symptoms or signs of pulmonary embolism. One hundred forty-one indium study patients also underwent Doppler ultrasonography/impedance plethysmography (Doppler/IPG) as a comparative non-invasive technique. In 137 cases, the results of the indium study and Doppler/IPG studies were congruent. The indium study had no false negative results that were detected by Doppler/IPG. No patient had any clinically evident toxicity. These results suggest that indium-111 labeled platelet scanning is a safe, noninvasive means for identifying DVT in high risk patients

    2011-05-01

    Upper-extremity deep venous thrombosis is less common than lower-extremity deep venous thrombosis. However, upper-extremity deep venous thrombosis is associated with similar adverse consequences and is becoming more common in patients with complex medical conditions requiring central venous catheters or wires. Although guidelines suggest that this disorder be managed using approaches similar to those for lower-extremity deep venous thrombosis, studies are refining the prognosis and management of upper-extremity deep venous thrombosis. Physicians should be familiar with the diagnostic and treatment considerations for this disease. This review will differentiate between primary and secondary upper-extremity deep venous thromboses; assess the risk factors and clinical sequelae associated with upper-extremity deep venous thrombosis, comparing these with lower-extremity deep venous thrombosis; and describe an approach to treatment and prevention of secondary upper-extremity deep venous thrombosis based on clinical evidence.

  7. Asymptomatic Intrahepatic Portosystemic Venous Shunt: To Treat or Not To Treat?

    2016-09-01

    Intrahepatic portosystemic venous shunts (IPSVSs) are rare vascular malformations. They can be asymptomatic or present with various symptoms including encephalopathy. We present two cases of IPSVS, one involving a patient presenting with altered mental status and the other discovered incidentally. While there is no question that patients presenting with symptomatic IPSVS should undergo definitive treatment, there is no consensus regarding elective therapy for asymptomatic lesions.

  8. The aetiology of deep venous thrombosis.

    Science.gov (United States)

    Malone, P C; Agutter, P S

    2006-09-01

    Most ideas about the pathogenesis of deep venous thrombosis (DVT) are dominated by a 'consensus model' first articulated around 1962. This model invokes 'Virchow's triad' and attributes thrombogenesis in veins to some combination of 'hypercoagulability', 'stasis' and 'intimal injury'. This arose as a by-product of studies on the mechanisms of haemostasis and bleeding diatheses that were at best only indirectly relevant to thrombosis, and there are reasons for doubting the causal significance of 'hypercoagulability' and 'stasis' in the aetiology of DVT. Proponents of the consensus model make little reference to a substantial literature, mostly historical, that: (a) emphasizes the significance of the venous valve pockets (VVP) and blood rheology in DVT pathogenesis; and (b) describes morphological features specific to venous thrombi that a valid aetiological model must explain. This literature provides the basis for an alternative hypothesis of DVT aetiology, published some 30 years ago, which has been experimentally corroborated and is compatible with recent cell and molecular biological studies of the venous endothelium. We review this alternative hypothesis, considering its potential value for future research on DVT and embolism, and its significance for clinical practice.

  10. Absence of inferior vena cava in 14-year old boy associated with deep venous thrombosis and positive Mycoplasma pneumoniae serum antibodies- a case report

    OpenAIRE

    Kalicki, Boleslaw; Sadecka, Monika; Wawrzyniak, Agata; Kozinski, Piotr; Dziekiewicz, Miroslaw; Jung, Anna

    2015-01-01

    Background Absence of the inferior vena cava is a rare vascular anomaly, which usually remains asymptomatic in childhood. It is recognized as the risk factor for deep venous thrombosis, since the collateral circulation does not provide adequate drainage of the lower limbs. Mycoplasma pneumoniae is a common cause of community-acquired pneumonia in school-aged children and adolescents. Mycoplasma pneumoniae infection might be associated with deep venous thrombosis but its pathophysiology remain...

    The purpose of this study was to highlight the critical role that MRI may play in diagnosing unsuspected lower extremity deep venous thrombosis and to stress the importance of scrutinizing MRI studies of the lower extremity showing apparently non-specific muscle edema for any evidence of intramuscular venous thrombosis. The imaging studies of four patients in whom deep venous thrombosis was unsuspected on clinical grounds, and first diagnosed on the basis of MRI findings, were reviewed by two musculoskeletal radiologists in consensus. In all four patients the initial clinical suspicion was within the scope of musculoskeletal injuries (gastrocnemius strain, n=3; ruptured Baker cyst, n=1), explaining the choice of MRI over ultrasound as the first diagnostic modality. All patients showed marked reactive edema in the surrounding soft tissues or muscles. Three patients showed MR evidence of branching rim-enhancing structures within intramuscular plexuses characteristic of venous thrombosis (gastrocnemius, n=1; sural, n=2); one patient showed a distended popliteal vein. Ultrasound was able to duplicate the MRI findings in three patients: one patient showed above-the-knee extension on ultrasound; neither of the two patients with intramuscular thrombosis demonstrated on ultrasound showed extension to the deep venous trunks. Intramuscular venous thrombosis can present as marked edema-like muscle changes on MRI, simulating primary musculoskeletal conditions. In the absence of clinical suspicion for deep venous thrombosis, only the identification of rim-enhancing branching intramuscular tubular structures will allow the correct diagnosis to be made.

  12. Deep venous thrombosis and postthrombotic syndrome: invasive management.

    Science.gov (United States)

    Comerota, A J

    2015-03-01

    Invasive management of postthrombotic syndrome encompasses the two ends of the deep vein thrombosis spectrum, patients with acute iliofemoral deep vein thrombosis and those with chronic postthrombotic iliofemoral venous obstruction. Of all patients with acute deep vein thrombosis, those with involvement of the iliofemoral segments have the most severe chronic postthrombotic morbidity. Catheter-based techniques now permit percutaneous treatment to eliminate thrombus, restore patency, potentially maintain valvular function, and improve quality of life. Randomized trial data support an initial treatment strategy of thrombus removal. Failure to eliminate acute thrombus from the iliofemoral system leads to chronic postthrombotic obstruction of venous outflow. Debilitating chronic postthrombotic symptoms of the long-standing obstruction of venous outflow can be reduced by restoring unobstructed venous drainage from the profunda femoris vein to the vena cava.

  13. Deep venous thrombosis and pulmonary embolism in psychiatric settings

    Directory of Open Access Journals (Sweden)

    Els G. Van Neste

    2009-03-01

    Full Text Available Background and objectives: Deep venous thrombosis and pulmonary embolism are serious, possibly life-threatening events which are often ignored in psychiatric settings. This article investigates which psychiatric patients are at increased risk of developing a venous thromboembolism. To our knowledge we are the first to perform a literature review of clinical studies relating venous thrombosis and pulmonary embolism to psychotropic drugs and mental disorders. Methods: A Medline search for English studies using the appropriate search terms was performed. In addition, cross references of the relevant articles` literature references were considered. We withheld 12 observational studies, 29 case-reports and one review-article. Results: We found evidence that low potency antipsychotic drugs like chlorpromazine and thioridazine, and clozapine for treatment of resistant schizophrenia have an increased risk of venous thromboembolism. There is no evidence that antidepressants, benzodiazepines or mood stabilizers have a similar effect. Also psychiatric conditions like physical restraint, catatonia and neuroleptic malignant syndrome are related to a higher incidence of deep venous thrombosis. Conclusions: Limitations of the studies and hypotheses about underlying biological mechanisms are reviewed. The rationale for prophylactic measures is discussed and recommendations to prevent deep venous thrombosis and pulmonary embolism are given.

  14. Deep Venous Thrombosis Associated With Inferior Vena Cava Abnormalities And Hypoplastic Kidney In Siblings

    2016-06-01

    Full Text Available Congenital inferior vena cava anomalies have a reduced frequency in general population, many times being an asymptomatic finding. Patients caring such anomalies are at risk to develop deep vein thrombosis. In this paper, we present 2 siblings with deep venous thrombosis and inferior vena cava abnormalities, with a symptomatic onset at similar age. The inferior vena cava abnormality was documented by an angio-CT in each case. The thrombophilic workup was negative. Patients were treated with conservative therapy: low molecular weight heparin anticoagulants converted later to oral anticoagulant with resolution of symptoms and disappearance of the thrombus. Finally, in the absence of any risk factor in a young patient admitted with deep vein thrombosis investigations to exclude inferior vena cava anomalies are mandatory.

    The finding of muscle edema restricted to a single muscle compartment on MRI usually indicates a diagnosis of traumatic injury, myositis, denervation or neoplasm. This case demonstrates that deep venous thrombosis can also be the cause of isolated deep posterior compartment muscle edema in the calf and should be considered in the differential diagnosis even in the absence of diffuse soft tissue or subcutaneous edema.

  16. To what extent might deep venous thrombosis and chronic venous insufficiency share a common etiology?

    Science.gov (United States)

    Malone, P Colm; Agutter, P S

    2009-08-01

    According to the valve cusp hypoxia hypothesis (VCHH), deep venous thrombosis is caused by sustained non-pulsatile (streamline) venous blood flow. This leads to hypoxemia in the valve pockets; hypoxic injury to the inner (parietalis) endothelium of the cusp leaflets activates the elk-1/egr-1 pathway, leading to leukocyte and platelet swarming at the site of injury and, potentially, blood coagulation. Here, we propose an extension of the VCHH to account for chronic venous insufficiency. First, should the foregoing events not proceed to frank thrombogenesis, the valves may nevertheless be chronically injured and become incompetent. Serial incompetence in lower limb valves may then generate ''passive'' venous hypertension. Second, should ostial valve thrombosis obstruct venous return from muscles via tributaries draining into the femoral vein, as Virchow illustrated, ''active'' venous hypertension may supervene: muscle contraction would force the blood in the vessels behind the blocked ostial valves to re-route. Passive or active venous hypertension opposes return flow, leading to luminal hypoxemia and vein wall distension, which in turn may impair vasa venarum perfusion; the resulting mural endothelial hypoxia would lead to leukocyte invasion of the wall and remodelling of the media. We propose that varicose veins result if gross active hypertension stretches the valve ''rings'', rendering attached valves incompetent caudad to obstructed sites, replacing normal centripetal flow in perforating veins with centrifugal flow and over-distending those vessels. We also discuss how hypoxemia-related venous/capillary wall lesions may lead to accumulation of leukocytes, progressive blockage of capillary blood flow, lipodermosclerosis and skin ulceration.

    Only a small number of venous leiomyosarcomas have been previously reported. Of these tumors, those of saphenous origin comprise a minority of cases. A 59-year-old man presented with symptoms of deep vein thrombosis and was eventually diagnosed with primary leiomyosarcoma of great saphenous vein origin. The tumor was treated with primary resection and femoral vein reconstruction with autologous patch. Although extremely rare, saphenous leiomyosarcoma can present as deep vein thrombosis. Vascular tumors should be included in the differential diagnosis of atypical extremity swelling refractory to conventional deep vein thrombosis management.

  18. Novel Biomarkers Associated with Deep Venous Thrombosis: A Comprehensive Review

    Dawn M Barnes

    2007-01-01

    Full Text Available Primary and recurrent venous thromboembolic disease (VTE, deep venous thrombosis and pulmonary embolism remain a significant source of morbidity and mortality in the hospitalized patient. Non-specific subjective complaints and lack of specific objective findings related to acute deep venous thrombosis (DVT and pulmonary embolism (PE complicate the diagnosis. There remains no single serum marker available to exclusively confirm the diagnosis of VTE. While D-dimer is highly sensitive and useful for diagnostic exclusion, it lacks the specificity necessary for diagnostic confirmation resulting in the need for a variety of additional studies (i.e.: duplex ultrasound, venography, V/Q scanning, helical thoracic and pelvic CT scans and pulmoary angiography. There is evolving research supporting the utility of various plasma markers as novel “biomarkers” for VTE including selectins, microparticles, interleukin-10 and other cytokines. This review attempts to examine recent literature assessing the utility of P-selectin, microparticles, D-dimer, E-selectin, thrombin, interleukins and fibrin monomers in the diagnosis and guidance of therapy for VTE.

  19. Sarcoidosis, Celiac Disease and Deep Venous Thrombosis: a Rare Association

    2011-11-01

    Full Text Available Sarcoidosis is a multisystem granulomatous disorder of unknown etiology and it may rarely be associated with a second disorder. Celiac disease is an immune-mediated enteropathy characterized with malabsorption caused by gluten intolerance, and several reports indicate an association between celiac disease and sarcoidosis. In addition, although celiac disease is associated with several extraintestinal pathologies, venous thrombosis has been rarely reported. Herein we present a rare case report of a patient with a diagnosis of sarcoidosis, celiac disease and deep venous thrombosis because of the rare association of these disorders. The patient was admitted with abdominal pain, weight loss, chronic diarrhea and a 5-day history of swelling in her right leg. A diagnosis of deep venous thrombosis was achieved by doppler ultrasonographic examination. The diagnosis of celiac disease was made by biopsy of duodenal mucosa and supported with elevated serum level of anti-gliadin IgA and IgG, and a diagnosis of sarcoidosis was achieved by transbronchial needle aspiration from the subcarinal lymph node during flexible bronchoscopy.

  1. Iodine-123 miniplasmin for the detection of deep venous thrombosis

    International Nuclear Information System (INIS)

    Human plasminogen (MW 90'000) is cleaved by elastase into several fragments, including one with a molecular weight of 38'000 (mini-plasminogen). This fragment retains sufficiently preserved fibrin binding sites but lacks the affinity for α2-antiplasmin. Therefore radiolabelled miniplasmin was tested in 21 patients with suspected deep venous thrombosis, in 5 patients with lymphedema and in 5 healthy controls for its potential use as fast marker of deep venous thrombosis. 250 μCi of Iodine-123 miniplasmin was given i.v. after previous activation with 3000 IU urokinase. The tracer distribution was measured 15, 30 and 60 minutes after injection at 10 points over each leg. The mean left/right ratio obtained in the 5 volunteers was 1.04 (range 0.89-1.12). In the patients the test was considered positive when the left/right ratio was greater than 1.15 or smaller than 0.85 at two adjacent locations and in two consecutive measuring times. In the 21 patients studied both tests gave concurrent results in 19, while in one patient with a positive and in one patient with a negative phlebography the miniplasmintest gave opposite results. In 4 of the 5 patients with edema and no thrombosis the miniplasmintest was negative. Most positive tests were conclusive as early as 15 minutes after injection of miniplasmin. The sensitivity was calculated to be 90% and the specificity 85%. Therefore Iodine-123 miniplasmin has been estimated as a fast, non invasive marker for the diagnosis of deep venous thrombosis and preliminary clinical studies with scintigraphy have been performed on over 50 patients. Evaluation gave a sensitivity between 40% and 86% and a specificity between 62% and 100%. Clinical studies have not been continued. Since I-123 miniplasmin is not available around the clock, it can't be used in emergency diagnosis. (author) 2 figs., 5 tabs., 30 refs

    Full Text Available Abstract Background Cirrhotic patients are characterized by a decreased synthesis of coagulation and anticoagulation factors. The coagulopathy of cirrhotic patients is considered to be auto-anticoagulation. Our aim was to determine the incidence and predictors of venous thromboembolism (VTE and examine the practice of deep venous thrombosis (DVT prophylaxis among hospitalized cirrhotic patients. Methods A retrospective cohort study was performed in a tertiary teaching hospital. We included all adult patients admitted to the hospital with a diagnosis of liver cirrhosis from January 1, 2009 to December 31, 2009. We grouped our cohort patients in two groups, cirrhotic patients without VTE and cirrhotic with VTE. Results Over one year, we included 226 cirrhotic patients, and the characteristics of both groups were similar regarding their clinical and laboratory parameters and their outcomes. Six patients (2.7% developed VTE, and all of the VTEs were DVT. Hepatitis C was the most common (51% underlying cause of liver cirrhosis, followed by hepatitis B (22%; 76% of the cirrhotic patients received neither pharmacological nor mechanical DVT prophylaxis. Conclusion Cirrhotic patients are at risk for developing VTE. The utilization of DVT prophylaxis was suboptimal.

    Isolated distal deep-vein thromboses (DVT) are infra-popliteal DVT without involvement of proximal veins or pulmonary embolism (PE). They can affect deep calf (tibial anterior, tibial posterior, or peroneal) or muscular (gastrocnemius or soleal) veins. They represent half of all lower limbs DVT. Proximal and distal DVTs differ in terms of risk factor profile, proximal DVT being more frequently associated with chronic risk factors and distal DVT with transient ones. Their natural history (rate of spontaneous proximal extension) is debated leading to uncertainties on the need to diagnose and treat them with anticoagulant drugs. In the long term, the risk of venous thromboembolic recurrence is lower than that of proximal DVT and their absolute risk of post-thrombotic syndrome is unknown. French national guidelines suggest treating with anticoagulants for 6 weeks a first episode of isolated distal DVT provoked by a transient risk factor and treating for at least 3 months unprovoked or recurrent or active cancer-related distal DVT. The use of compression stockings use is suggested in case of deep calf vein thrombosis. Ongoing therapeutic trials should provide important data necessary to establish an evidence-based mode of care, especially about the need to treat distal DVT at low risk of extension with anticoagulants.

    Aim To determine the prevalence of factor V Leiden mutation in patients with different presentation of venous thromboembolic disease and healthy individuals in the Republic of Macedonia. Methods The retrospective case-control study involved 190 patients with venous thromboembolic disease and 200 healthy individuals, who were screened for the presence of factor V Leiden mutation, using a polymerase chain reaction-restriction fragment length polymorphism method. The prevalence of factor V Leiden was analyzed according to the localization of thrombosis, presence of risk factors, and family history of thrombosis. The odds of deep venous thrombosis were calculated with respect to the presence of factor V Leiden mutation. Results The prevalence of factor V Leiden mutation among patients with venous thromboembolic disease was 21.1%, compared with 5.5% in the healthy individuals. Factor V Leiden positive patients had the first episode of deep venous thrombosis at a younger age, and the prevalence of the mutation was the highest among patients with a positive family history of thrombosis (33.9%, P = 0.003) and in patients with deep venous thrombosis affecting a large blood vessel (37.7%, P = 0.001). The prevalence of factor V Leiden mutation was lower in patients with calf deep venous thrombosis and primary thromboembolism (13.3% and 13.1%, respectively; P>0.05). The odds ratio for iliofemoral or femoral deep venous thrombosis in factor V Leiden carriers was 10.4 (95% confidence interval, 4.7-23.1). Conclusion The prevalence of factor V Leiden mutation was high in patients with venous thromboembolic disease and healthy individuals in the Republic of Macedonia. Factor V Leiden carriers have the highest odds of developing deep venous thrombosis affecting a large venous blood vessel. PMID:16758522

    Burned patients with deep venous thrombosis present a particularly perplexing challenge. They frequently require central venous catheters. Their altered skin integrity does not permit correlation with the typical changes described by the classic terminology for thrombophlebitis or its most severe forms, phlegmasia cerulea dolens or phlegmasia alba dolens. They are at risk of exsanguination or massive graft loss with lytic therapy or anticoagulation. Venous thrombectomy may be a necessary limb-saving surgical option.

    Cerebral venous thrombosis (CVT) and deep vein thrombosis or pulmonary embolism (DVT/PE) are associated with many risk factors. It is unclear why CVT occurs less often than DVT/PE. Age dependent risk factors may play a role. The aim of our study was to compare risk factors in a uniform age group of

    Full Text Available The increasing pressure of modern social life intensifies the impact of stress on the development of cardiovascular diseases, which include deep venous thrombosis (DVT. Renal sympathetic denervation has been applied as one of the clinical approaches for the treatment of drug-resistant hypertension. In addition, the close relationship between oxidative stress and cardiovascular diseases has been well documented. The present study is designed to explore the mechanism by which the renal sympathetic nerve system and the oxidative stress affect the blood coagulation system in the development of DVT. Chronic foot shock model in rats was applied to mimic a state of physiological stress similar to humans. Our results showed that chronic foot shock procedure could promote DVT which may be through the activation of platelets aggregation. The aggravation of DVT and activation of platelets were alleviated by renal sympathetic denervation or antioxidant (Tempol treatment. Concurrently, the denervation treatment could also reduce the levels of circulating oxidation factors in rats. These results demonstrate that both the renal sympathetic nerve system and the oxidative stress contribute to the development of DVT in response to chronic stress, which may provide novel strategy for treatment of clinic DVT patients.

    Introduction. Primary venous tumours are a rare cause of deep vein thrombosis. The authors present a case where the definitive diagnosis was delayed by inconclusive complementary imaging. Clinical Case. A thirty-seven-year-old female presented with an iliofemoral venous thrombosis of the right lower limb. The patient had presented with an episode of femoral-popliteal vein thrombosis five months before and was currently under anticoagulation. Phlegmasia alba dolens installed progressively, as thrombus rapidly extended to the inferior vena cava despite systemic thrombolysis and anticoagulation. Diagnostic imaging failed to identify the underlying aetiology of the deep vein thrombosis. The definitive diagnosis of primary venous leiomyosarcoma was reached by a subcutaneous abdominal wall nodule biopsy. Conclusion. Primary venous leiomyosarcoma of the iliac vein is a rare cause of deep vein thrombosis, which must be considered in young patients with recurrent or refractory to treatment deep vein thrombosis.

    Full Text Available Inferior vena cava atresia (IVCA is a rare but well described vascular anomaly. It is a rare risk factor for deep venous thrombosis (DVT, found in approximately 5% of cases of unprovoked lower extremity (LE DVT in patients <30 years of age. Affected population is in the early thirties, predominantly male, often with a history of major physical exertion and presents with extensive or bilateral DVTs. Patients with IVC anomalies usually develop compensatory circulation through the collateral veins with enlarged azygous/hemizygous veins. Despite the compensatory circulation, the venous drainage of the lower limbs is often insufficient leading to venous stasis and thrombosis. We describe a case of extensive and bilateral deep venous thrombosis following physical exertion in a thirty-six-year-old male patient with incidental finding of IVCA on imaging.

  17. Advanced management of acute iliofemoral deep venous thrombosis: emergency department and beyond.

    2011-06-01

    Recent attention to the increasing incidence of venous thromboembolism has included a call to action from the surgeon general and new guidelines from various specialty organizations. The standard of care for treatment of deep venous thrombosis in the emergency department (ED), supported by the 2008 American College of Chest Physicians (ACCP) guidelines, involves initiation of anticoagulation with low-molecular-weight heparin, pentasaccharide, or unfractionated heparin. For selected appropriate patients with extensive acute proximal deep venous thrombosis, the ACCP guidelines now recommend thrombolysis in addition to anticoagulation to reduce not only the risk of pulmonary embolism but also the risk of subsequent postthrombotic syndrome and recurrent deep venous thrombosis. Postthrombotic syndrome is a potentially debilitating chronic cluster of lower-extremity symptoms occurring in 20% to 50% of deep venous thrombosis patients subsequent to the acute insult, sometimes not until years later. A strategy of early thrombus burden reduction or frank removal might reduce the incidence of postthrombotic syndrome, as per natural history studies, venous thrombectomy data, observations after systemic and catheter-directed thrombolysis, and the still-limited number of randomized trials of catheter-directed thrombolysis (with anticoagulation) versus anticoagulation alone. Contemporary invasive (endovascular) treatments mitigate the drawbacks historically associated with thrombolytic approaches by means of intrathrombus delivery of drugs with greater fibrin specificity and lower allergenicity, followed by mechanical dispersion to accelerate lysis and then aspiration of remaining drug and clot debris. With a 2016 target completion date, the National Heart, Lung, and Blood Institute--sponsored Acute Venous Thrombosis: Thrombus Removal With Adjunctive Catheter-Directed Thrombolysis trial is comparing the safety and efficacy, in terms of both deep venous thrombosis and

    Full Text Available OBJECTIVE: to determine the incidence of deep vein thrombosis and prophylaxis quality in hospitalized patients undergoing vascular and orthopedic surgical procedures. METHODS: we evaluated 296 patients, whose incidence of deep venous thrombosis was studied by vascular ultrasonography. Risk factors for venous thrombosis were stratified according the Caprini model. To assess the quality of prophylaxis we compared the adopted measures with the prophylaxis guidelines of the American College of Chest Physicians. RESULTS: the overall incidence of deep venous thrombosis was 7.5%. As for the risk groups, 10.8% were considered low risk, 14.9%moderate risk, 24.3% high risk and 50.5% very high risk. Prophylaxis of deep venous thrombosis was correct in 57.7%. In groups of high and very high risk, adequate prophylaxis rates were 72.2% and 71.6%, respectively. Excessive use of chemoprophylaxis was seen in 68.7% and 61.4% in the low and moderate-risk groups, respectively. CONCLUSION: although most patients are deemed to be at high and very high risk for deep vein thrombosis, deficiency in the application of prophylaxis persists in medical practice.

    Congenital anomalies of the inferior vena cava (IVC), although rare, are a risk factor for lower limb deep venous thrombosis (DVT). A 19-year-old male presented with a left flank and groin pain caused by iliofemoral venous thrombosis. Vascular imaging by computed tomography (CT) scanning and venography demonstrated agenesis of the IVC. Catheter-directed thrombolysis via a popliteal vein was attempted but did not alter the patency of the common femoral vein outflow collaterals into the retroperitoneal azygous venous system. The patient was anticoagulated using systemic heparin infusion and clinical symptoms resolved within 5 days. He was transitioned to oral Coumadin anticoagulation, and follow-up venous duplex testing demonstrated no infrainguinal DVT and phasic venous flow with respiration in the femoral vein indicating patent collateral veins. Anomalies of the IVC are present in 0.3-0.5% of otherwise healthy individuals. Agenesis of the IVC has an incidence of 0.0005-1% in the general population but is found in almost 5% of patients venous collaterals on noncontrast CT imaging. In young adults presenting with unprovoked lower limb DVT, the presence of an IVC anomaly should be considered and evaluated for by venous duplex testing and if necessary CT venography.

    Lower limb deep vein thrombosis (DVT) is a common cause of significant morbidity and mortality. Systemic anticoagulation therapy is the mainstay of conventional treatment instituted by most physicians for the management of DVT. This has proven efficacy in the prevention of thrombus extension and reduction in the incidence of pulmonary embolism and rethrombosis. Unfortunately, especially in patients with severe and extensive iliofemoral DVT, standard treatment may not be entirely adequate. This is because a considerable proportion of these patients eventually develops postthrombotic syndrome. This is characterized by chronic extremity pain and trophic skin changes, edema, ulceration, and venous claudication. Recent interest in endovascular technologies has led to the development of an assortment of minimally invasive, catheter-based strategies to deal with venous thrombus. These comprise catheter-directed thrombolysis, percutaneous mechanical thrombectomy devices, adjuvant venous angioplasty and stenting, and inferior vena cava filters. This article reviews these technologies and discusses their current role as percutaneous treatment strategies for venous thrombotic conditions.

    2014-09-01

    Deep venous thrombosis (DVT) in children is more often associated with underlying pathological conditions than with hereditary thrombophilia. The present study is a retrospective analysis of thrombophilia in 285 pediatric patients with venous thrombosis at different sites. Four common thrombophilia markers, that is protein C, protein S, antithrombin III, and factor V Leiden (FVL) mutation, were analyzed. Thrombosis in hepatic and portal veins was more common in pediatric patients (73%) when compared to other sites (27%). Overall, hereditary thrombophilia accounted for 15.5% of the patients with venous thrombosis. The FVL mutation, which was the major causative factor in Budd-Chiari syndrome and portal vein thrombosis cases in the adult group, was not a major contributing factor in pediatric group, that is, 1.8% of the patients. In conclusion, the risk factors for venous thrombosis vary in different age groups.

    Exact age determination of deep venous thrombosis (DVT) is important for an appropriate treatment. The purpose of this present study is to assess the age of acute DVT with the area of venous thrombi in elasticity imaging during the thrombosis procession. The thrombus area is obtained from a specially designed program. It was applied to clot specimens induced in human great saphenous (n = 15) at selected time points following the initiation of thrombosis. The relative mean proportion of blood clots was 50.01% ± 12.44% at day 1; 69.94% ± 8.19% at day 3; 81.93% ± 6.15% at day 6; and 92.37% ± 4.06% at day 9. The results indicated that the thrombus area increased significantly over time, while the normalized strain values inside the thrombus changed only a little. The pathological analyses also showed the same results. Therefore, we conclude that the area of venous thrombi in elasticity imaging may be a novel function for acute DVT staging.

    AIM To summarize the current knowledge on vascular complications and deep venous thrombosis (DVT) prophylaxis after anterior cruciate ligament (ACL) reconstruction. METHODS A systematic review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement. MEDLINE, EMBASE, Cochrane, Web of Science, CINAHL, PubMed publisher, and Google scholar medical literature databases were searched up to November 10, 2015. Any arthroscopic surgical method of primary or revision intra-articular ACL reconstruction of all graft types in humans was included. A risk of bias assessment was determined. RESULTS Fourty-seven studies were included in the review. Pseudaneurysms were the most frequently reported arterial complication after ACL reconstruction, irrespective of graft type or method of graft fixation with an incidence of 0.3%. The time to diagnosis of arterial complications after ACL reconstruction varied from days to mostly weeks but even years. After ACL reconstruction without thromboprophylaxis, the incidence of DVT was 9.7%, of which 2.1% was symptomatic. The incidence of pulmonary embolism was 0.1%. Tourniquet time > 2 h was related to venous thromboembolism. Thromboprophylaxis is indicated in patients with risk factors for venous thromboembolism. CONCLUSION After ACL reconstruction, the incidence of arterial complications, symptomatic DVT and pulmonary embolism was 0.3%, 2.1% and 0.1% respectively. Arterial complications may occur with all types of arthroscopic ACL reconstruction, methods of graft fixation as well as any type of graft. Patients considered to be at moderate or high risk of venous thromboembolism should routinely receive thromboprophylaxis after ACL reconstruction. PMID:27672574

    Full Text Available BACKGROUND: There is a knowledge gap with relation to the true incidence of deep vein thrombosis among patients undergoing vascular surgery procedures in Brazil. This study is designed to support the implementation of a surveillance system to control the quality of venous thromboembolism prophylaxis in our country. Investigations in specific institutions have determined the true incidence of deep vein thrombosis and identified risk groups, to enable measures to be taken to ensure adequate prophylaxis and treatment to prevent the condition.OBJECTIVE: To study the incidence of deep venous thrombosis in patients admitted to hospital for non-venous vascular surgery procedures and stratify them into risk groups.METHOD: This was a cross-sectional observational study that evaluated 202 patients from a university hospital vascular surgery clinic between March 2011 and July 2012. The incidence of deep venous thrombosis was determined using vascular ultrasound examinations and the Caprini scale.RESULTS: The mean incidence of deep venous thrombosis in vascular surgery patients was 8.5%. The frequency distribution of patients by venous thromboembolism risk groups was as follows: 8.4% were considered low risk, 17.3% moderate risk, 29.7% high risk and 44.6% were classified as very high risk.CONCLUSION: The incidence of deep venous thrombosis in vascular surgery patients was 8.5%, which is similar to figures reported in the international literature. Most vascular surgery patients were stratified into the high and very high risk for deep venous thrombosis groups.

    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.

    Full Text Available Abstract Introduction Postoperative pulmonary embolism is considered a complication of major surgery. However, thromboembolism can also occur following minor procedures. We report a case of a major embolic event following a straightforward office vasectomy. Case presentation A healthy 35-year-old Asian man underwent an uncomplicated office vasectomy. Soon after, he noticed vague chest pain and dyspnea. Lower extremity Doppler ultrasound revealed acute venous thrombosis. A computer-assisted tomography angiogram revealed extensive bilateral pulmonary emboli. Extensive laboratory work-up failed to identify thrombophilia. He has not had any recurrences in the eight years since the initial presentation. Conclusion This case highlights that major embolic events can follow minor office procedures. Patients with suggestive findings should be investigated aggressively.

  17. Relationship between deep venous thrombosis and pulmonary embolism by radionuclide techniques in 150 patients

    International Nuclear Information System (INIS)

    Objective: This study was to evaluate the relationship between deep venous thrombosis and pulmonary embolism assessed by radionuclide imaging. Methods: One hundred and fifty patients with pulmonary embolism from September 1997 to September 2001 were included. Pulmonary perfusion/ventilation imaging and deep venous radionuclide venography was performed in all patients. There were 87 men, and 63 women, with an average age 39±18 years. Of them, 26 underwent pulmonary arteriography. Eleven patients had X Ray phleography of lower extremities, 18 patients had Impedence plethymography (IPG), and 36 patients had lower limb ultrasound study. Results: Out of 150 patients with pulmonary embolism, 128 (85.5%) had lower limb venous pathological changes. Among them, 100 patients had risk factors of deep venous thrombosis (78.3%). 120 patients had proximal vein (80.0%). The agreement between radionuclide venography and X Ray phleography of lower extremities UCG and IPG was 90.9%, 70.2% and 80.0% respectively. Conclusions: Our results indicate that DVT was one of most important cause for acute pulmonary embolism, and thrombosis is mostly located in the proximal veins

    Venous thromboembolism is a known complication of cancer which impacts on patient mortality and quality of life. The primary site of cancer is an important risk factor, with highest rates observed in patients with brain, pancreas, gastric, kidney, ovary and lung cancers. The extent of metastatic spread further adds to the risk. In this article, we present the case of a young patient who was diagnosed with an aggressive form of pancreatic neoplasm with secondary determinations, without any previous digestive symptoms, with the occasion of a recurrent and migratory deep venous thrombosis (DVT).

    2004-07-01

    Pulmonary embolism and venous ischemia are acute complications of deep vein thrombosis (DVT) of the lower extremities. Delayed complications include a spectrum of debilitating symptoms referred to as postthrombotic syndrome (PST). Because the early symptoms and patient signs are nonspecific for DVT, careful history taking and radiological evaluation of the extent and migration of thrombus should be used to establish an objective diagnosis and the need for treatment. Anticoagulation therapy is recognized as the mainstay treatment in acute DVT. However, there are few data to suggest any major beneficial effect of the early clearing of massive DVT and PTS. Endovascular, catheter-directed, thrombolysis techniques, used alone or in combination with mechanical thrombectomy devices, have been proven to be highly effective in clearing acute DVT, which may allow the preservation of venous valve function and the prevention of subsequent venous occlusive disease. Definitive management of the underlying anatomic occlusive abnormalities should also be undertaken.

    Deep venous thrombosis (DVT) is an important cause of disability and mortality after major orthopedic surgery.The roles of perioperative treatment and prevention of DVT in patients with femoral neck fractures who require major surgery have not yet been well explored in Chinese clinical practice.Here we report a case of calf muscular venous thrombosis in a 55-year-old woman with femoral neck fracture before surgery.Preventive and treatment measures including the administration of heparin sodium, application of venous foot pump and placement of inferior vena cava filter were taken.The condition of the patient was stable during the perioperative period and the surgery was successful.Besides, postoperative examination showed that the femur healed well and the functional recovery was satisfactory.Our results suggest that femoral neck fracture patients combined with DVT can receive surgery after accurate preoperative assessment and proper preoperative treatment.

    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

    To evaluate the technical feasibility and clinical efficacy of the use of local thrombolysis for below-knee deep vein thrombosis (DVT). From a population of 41 patients with a lower extremity DVT, the prospective clinical trial included 11 patients (7 female, 4 male, average age 61.4 years) treated with catheter-directed thrombolysis with urokinase for below-knee DVT. After removal of the proximal ilofemoral DVT, additional interventional procedures to remove the residual thrombosis and restore the venous flow from the below-knee vein were performed in cases of continuous occlusion of venous flow from the popliteal and tibial veins. Under ultrasound (US) guidance, catheter-directed thrombolysis with urokinase was performed through the ipsilateral popliteal vein. After administration of oral anticoagulation therapy, CT and venography were performed to identify patency and the presence of a recurrent thrombosis. Successful removal of the thrombus and restoration of venous flow were achieved in all of the patients (100%). Restoration of flow with a residual thrombus occurred in one case. Focal venous stenosis was discovered in four cases. The duration of urokinase infusion was 1-4 days (average 2.36 days), which was considered long. For 15.2 months, the venous lumen of all cases was preserved without a recurrent thrombosis. Catheter-directed thrombolysis is an effective procedure for recanalization of below-knee DVT in patients with a lower extremity DVT.

    Significant spontaneous thrombus disintegration in deep venous thrombosis (DVT) occurs very infrequently. On the contrary, these thrombi are prone to appositional growth and migration into the pulmonary arteries. The development of chronic venous insufficiency due to postthrombotic syndrome is a frequent consequence of DVT. Therapeutic options in DVT include anticoagulation and recanalising procedures such as thrombolysis and thrombectomy. After appropriate indication assessment, the interventional radiologist can offer an efficacy-proven minimally-invasive vessel restitution approach by performing locoregional thrombolysis, pharmacomechanical therapy or, particularly in iliocaval thrombosis, mechanical thrombectomy. These methods not only serve to restitute of vessel patency, but also allow preserving venous valve function. In DVT with recurrent pulmonary embolism, retrievable filters with extended implantation duration can be deployed. In chronic proximal venous flow obstruction or in case of significant residual stenosis after thrombolysis, balloon angioplasty with stent implantation is the treatment modality of choice. Consequently, the radiologist can adopt an important role in the treatment of extensive venous disease. In this article, the treatment modalities concerning iliofemoral and iliocaval thrombosis are demonstrated and illustrated. (orig.)

    Deep white matter hemorrhagic venous infarction with subsequent cavitation due to necrosis and liquefaction has been described in neonates and may be associated with infection and meningitis. In our experience, the MRI pattern of these lesions is confused with the pattern seen with cerebral abscesses. The purpose of our study was to characterize the MRI findings of post infarction necrosis and liquefaction after hemorrhagic deep white matter venous infarction in infants and to distinguish these lesions from cerebral abscesses. An institutional review board approved a retrospective review of imaging records to identify all patients with cerebral venous infarction at a children's hospital during a 10-year period. Nine infants had deep white matter hemorrhagic venous infarction with white matter fluid signal cavitary lesions. A diagnosis of cerebral abscess was considered in all. The imaging and laboratory findings in these patients are reviewed and compared to descriptions of abscesses found in the literature. There were six female and three male infants. The mean age at presentation was 20 days (range: 0-90 days), while the corrected age at presentation was less than 30 days for all patients. Seven patients presented with seizures and signs of infection; one infant presented with lethargy and later proved to have protein C deficiency. MRI was performed 0-12 days from presentation in these eight patients. Another patient with known protein C deficiency underwent MRI at 30 days for follow-up of screening US abnormalities. There were a total of 38 deep cerebral white matter fluid signal cavitary lesions: 25 frontal, 9 parietal, 2 temporal, 2 occipital. Larger lesions had dependent debris. All lesions had associated hemorrhage and many lesions had evidence of adjacent small vessel venous thrombosis. Lesions imaged after gadolinium showed peripheral enhancement. Three lesions increased in size on follow-up imaging. Three patients, two with meningitis confirmed via

    Full Text Available A 42-year-old woman, gravida 3, para 3 was admitted to hospital because of painful oedema of her right lower extremity. Initial physical examination revealed a gross, firm tumour filling the entire peritoneal cavity. Doppler ultrasound scan revealed a thrombus in the right common iliac vein, extending to the right femur and popliteal veins, and partially into the calf deep vein. Computed tomography confirmed the existence of an abdominal tumour probably deriving from the genital organs and the presence of a thrombus in the said veins.The patient underwent hysterectomy where a myomatous uterine was removed. She was put on subcutaneous enoxaparine and compressive therapy of the lower extremities. Such symptoms as pain and oedema receded. Control Doppler scan showed fibrinolysis, partial organization of the thrombus and final vein recanalisation. After exclusion of other risk factors of deep vein thrombosis apart from stasis, we conclude that the described pathology was the effect of compression of regional pelvic structures by a uterine myoma.

    The experimental procedure by which the valve cusp hypoxia (VCH) hypothesis of the etiology of deep venous thrombosis (DVT) was confirmed lends itself to testing of methods of prophylaxis. Similar animal experiments could end the present exclusive reliance on statistical analysis of data from large patient cohorts to evaluate prophylactic regimes. The reduction of need for such (usually retrospective) analyses could enable rationally-based clinical trials of prophylactic methods to be conduct...

    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 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.

    The valve cusp hypoxia thesis (VCHT) of the aetiology of deep venous thrombosis (DVT) was adumbrated in this journal in 1977 and fully articulated in 2008, the original hypothesis having been strongly corroborated by experiments published in 1981 and 1984. It presents a unitary account of the pathogenesis of venous thrombosis and embolism that is rooted in the pathophysiological tradition of Hunter, Virchow, Lister, Welch and Aschoff, a tradition traceable back to Harvey. In this paper we summarise the thesis in its mature form, consider its compatibility with recent advances in the DVT field, and ask why it has not yet been assimilated into the mainstream literature, which during the past half century has been dominated by a haematology-orientated 'consensus model'. We identify and discuss seven ways in which the VCHT is incompatible with these mainstream beliefs about the aetiology of venous thrombosis, drawing attention to: (1) the spurious nature of 'Virchow's triad'; (2) the crucial differences between 'venous thrombus' and 'clot'; the facts that (3) venous thrombi form in the valve pockets (VVPs), (4) DVT is not a primarily haematological condition, (5) the so-called 'thrombophilias' are not thrombogenic per se; (6) the conflict between the single unitary aetiology of DVT and the tacit assumption that the condition is 'multicausal'; (7) the inability of anticoagulants to prevent the initiation of venous thrombogenesis, though they do prevent the growth of thrombi to clinically significant size. In discussing point (7), we show that the VCHT indicates new approaches to mechanical prophylaxis against DVT. These approaches are then formulated as experimentally testable hypotheses, and we suggest methods for testing them preclinically using animal trials.

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.

    2014-06-01

    Patients with postthrombotic syndrome due to previous femoral-popliteal deep venous thrombosis often experience lifestyle-limiting lower-extremity pain and swelling. Conservative treatment options include compression stockings and lymphedema massage, but in many cases these treatments only temporarily and partially improve symptoms. Ultrasound and venography in patients with postthrombotic syndrome often show only partial recanalization of the femoral vein with significant collateral vein formation. These abnormal veins are insufficient for adequate venous drainage from the lower extremity as evidenced by the patient's continued symptoms. Recanalization of the occluded or partially occluded femoral vein using prolonged venoplasty, with or without chemical thrombolysis, combined with optimizing anticoagulation and conservative treatment measures, results in lasting improvement in symptoms for a high percentage of patients.

    This study reviews the clinical and workforce impact of a suggested protocol designed for the management of suspected acute deep venous thrombosis (DVT) in patients seen after standard vascular laboratory business hours. The protocol included the use of Wells score, D-dimer and a single dose of therapeutic anticoagulant to defer venous duplex ultrasound (VDU) testing until routine business hours unless contraindicated. Information was collected on medical history, physical exam and the timing of any diagnostic studies and treatment provided. Over 15% of studies done after-hours were deemed unnecessary by our protocol and in every individual the results were negative for an acute DVT. There were no adverse events from a one-time dose of anticoagulant. Limiting emergency VDU coverage to evaluate for acute DVT based on a management protocol can eliminate unnecessary after-hours VDU testing without having a negative impact on patient care.

    Accurate diagnosis of deep venous thrombosis (DVT) can be achieved through appropriate use of the various imaging and non-imaging techniques currently available in clinical practice. This paper summarizes the roles of imaging techniques such as duplex ultrasound, contrast and radionuclide venography, and magnetic resonance imaging, as well as clinical prediction models and D-dimer testing, in the evaluation of patients with suspected DVT. Recent data examining the prognostic value of several of these tests, alone and in combination, are also reviewed. The associations of testing for DVT and pulmonary embolism, and the controversies which sometimes surround them, are also briefly examined.

    Conclusions: The natural history of thromboembolism in plastic surgery outpatients differs from orthopedic patients. The risk of a deep venous thrombosis in a patient treated with Spontaneous breathing, Avoid gas, Face up, Extremities mobile anesthesia is approximately 0.5%. Thromboses are unlikely to develop intraoperatively. In the single affected patient, the thrombosis was located distally, in a location that is less prone to embolism and highly susceptible to anticoagulation. Ultrasound screening is an effective and highly feasible method to identify affected patients for treatment.

Three cases were identified, representing 2% of cases overall (3/160): a 44-year-old woman with a large uterine leiomyoma (1048 g); a 74-year-old man with prostatomegaly and bladder distension (containing 1 L of urine); and a 70-year-old man with prostatomegaly and bladder distension (containing 3 L of urine). Although a rare cause of fatal deep venous thrombosis and pulmonary thromboembolism, space-occupying pelvic lesions can lead to extrinsic pressure on adjacent veins reducing blood flow and causing stasis and thrombosis. Individuals with large pelvic masses may, therefore, be at increased risk of pulmonary thromboembolism from deep venous thrombosis, particularly in the presence of concurrent risk factors such as immobility, thrombophilias, malignancy, and significant cardiopulmonary disease.

    The aims of this study were to optimize image quality for indirect CT venography (sequential versus spiral), and to evaluate different image reconstruction parameters for patients with suspected deep venous thrombosis (DVT). Fifty-one patients (26/25 with/without DVT) were prospectively evaluated for pulmonary embolism (PE) with standard multidetector-row computed tomography (MDCT) protocols. Retrospective image reconstruction was done with different slice thicknesses and reconstruction increments in sequential and spiral modes. All reconstructions were read for depiction of DVT and to evaluate best reconstruction parameters in comparison with the thinnest reconstruction (''gold standard''). Image noise and venous enhancement were measured as objective criteria for image quality. Subjective image quality was rated on a four-point scale. Effective dose was estimated for all reconstructions. In sequential 10/50 reconstruction DVT was completely detected in 13/26 cases, partially in 10/26 cases and was not detected at all in 3/26 cases, and 15/26, 9/26 and 2/26 cases for the 10/20 reconstruction, respectively. DVT was completely detected in all spiral reconstructions. Image noise ranged between 14.8-29.1 HU. Median image quality was 2. Estimated effective dose ranged between 2.3 mSv and 11.8 mSv. Gaps in sequential protocols may lead to false negative results. Therefore, spiral scanning protocols for complete depiction of DVT are mandatory. (orig.)

    Abstract Background: Hypereosinophilic syndrome (HES) can be fatal, particularly when eosinophils infiltrate vital organs and/or if extensive thrombosis develops. However there are no standard recommendations for the use of anticoagulant therapy of HES in the setting of thrombosis. Methods: We herein present a case of a 46-year-old female who presented with marked peripheral eosinophilia with symptoms of multi-organ infiltration and extensive deep venous thrombosis (DVT). In this case, evaluation was carried out before the diagnosis was established, and timely standard-dose corticosteroids combined with a new oral anticoagulant (NOAC) therapy were carried out. Results: These measures resulted in a rapid response and long-term disease control. Conclusion: Although there are no data to support which anticoagulant is preferred in this setting, this case indicates that the new oral anticoagulants may play an important role in the treatment of thrombosis in HES.

    One hundred and thirty-four patients admitted to the medical emergency ward due to suspected deep venous thrombosis (DVT) were examined. The uptake of intravenously injected porcine /sup 99/Tcsup (m)-plasmin was estimated in both legs. Thereafter, phlebography was performed using a high osmolar contrast medium. All phlebographies were evaluated independently. All patients with negative phlebography were examined after 3-5 days. The plasmin test and phlebography were repeated when called for. The sensivity of the plasmin test was 100% and the specificity 51% when compared to phlebography. The extension of the DVT as demonstrated by the plasmin test was similar to that determined by phlebography. Post-phlebographic trombosis was very rare. It is concluded that /sup 99/Tcsup (m)-plasmin test is a rapid method, convenient to the patient and well suitable as a screening test. The results indicate that a negative plasmin test excludes DVT while a positive test necessitates additional examination by phlebography.

    Venous thromboembolism (VTE) represents the third leading cause of cardiovascular mortality, and it is the main cause of preventable mortality in hospitalized patients. Among VTE, there is the unique case of isolated distal deep vein thrombosis (IDDVT), which still lacks an agreement in terms of optimal therapeutic strategy. Although most IDDVTs are self-limiting and associated with a very low risk of embolic complications, still not all IDDVTs can be safely identified as stable. Lack of strong scientific evidence, fear of thromboembolic complications, and risk of bleeding upon initiation of anticoagulant treatment result in very heterogeneous therapeutic strategies among physicians. Here, we provide a comprehensive review of the literature, highlight the many controversial issues regarding IDDVTs, and call for a consensus of experts aimed to shed new light on the gray areas of IDDVT management and therapy.

    We investigated the association between the development of deep venous thrombosis (DVT) and calf vein diameter in patients with acute hemorrhagic stroke. We measured the maximum diameter of paralytic side posttibial veins (PTVs) and peroneal veins (PVs) in 49 patients with intracerebral hemorrhage on admission and at 2 weeks after stroke onset by ultrasonography. We also examined for the presence or absence of DVT, and then analyzed the association of DVT with the maximum vein diameter. At 2 weeks after stroke, DVTs were detected in PTVs in 7 patients and in PVs in 6 patients. The maximum calf vein diameters at 2 weeks were significantly greater in patients with DVT compared with those without DVT (PTV, P = .033; PV, P = .015). Although calf vein diameter at admission did not influence the future incidence of DVT in patients with intracerebral hemorrhage, the presence of DVT was associated with calf vein dilatation.

  15. The role of interventional radiology in the management of deep venous thrombosis: advanced therapy.

    2011-06-01

    Deep vein thrombosis (DVT) is often managed with a health care pathway that funnels patients to anticoagulation therapy alone. This "usual treatment" is designed to stop propagation and embolisation of venous thrombus but not remove it. Surgical thrombectomy was once the only option in severe cases in which limbs were threatened, but thrombus removal is no longer restricted to emergency cases. Interventional radiologists are now using advanced endovascular techniques to achieve thrombus removal in a minimally invasive manner in a very short treatment time, thereby quickly restoring patency, relieving acute symptoms, and potentially limiting the subsequent development of postthrombotic syndrome when followed with anticoagulation and compression regimens. This article provides an overview of the interventions available for treating DVT. One of the newer "single-session" techniques is isolated pharmacomechanical thrombolysis, which is described here in detail with supporting cases.

    2016-01-01

    Introduction Unilateral leg swelling with suspicion of deep venous thrombosis (DVT) is a common emergency department (ED) presentation. Proximal DVT (thrombus in the popliteal or femoral veins) can usually be diagnosed and treated at the initial ED encounter. When proximal DVT has been ruled out, isolated calf-vein deep venous thrombosis (IC-DVT) often remains a consideration. The current standard for the diagnosis of IC-DVT is whole-leg vascular duplex ultrasonography (WLUS), a test that is unavailable in many hospitals outside normal business hours. When WLUS is not available from the ED, recommendations for managing suspected IC-DVT vary. The objectives of the study is to use current evidence and recommendations to (1) propose a diagnostic algorithm for IC-DVT when definitive testing (WLUS) is unavailable; and (2) summarize the controversy surrounding IC-DVT treatment. Discussion The Figure combines D-dimer testing with serial CUS or a single deferred FLUS for the diagnosis of IC-DVT. Such an algorithm has the potential to safely direct the management of suspected IC-DVT when definitive testing is unavailable. Whether or not to treat diagnosed IC-DVT remains widely debated and awaiting further evidence. Conclusion When IC-DVT is not ruled out in the ED, the suggested algorithm, although not prospectively validated by a controlled study, offers an approach to diagnosis that is consistent with current data and recommendations. When IC-DVT is diagnosed, current references suggest that a decision between anticoagulation and continued follow-up outpatient testing can be based on shared decision-making. The risks of proximal progression and life-threatening embolization should be balanced against the generally more benign natural history of such thrombi, and an individual patient’s risk factors for both thrombus propagation and complications of anticoagulation.

    Malignant tumors arising in deep veins of the lower extremities are very uncommon. To our best knowledge, this is the seventh case of a primary venous intravascular synovial sarcoma (SS) reported in literature. A 32-year-old woman was admitted with a second episode of deep venous thrombosis of the right lower limb and pulmonary embolism. Physical and radiological examinations showed besides the thrombosis a tumor arising from the right common femoral vein involving the bifurcation of the common femoral artery. At surgery, en block resection of the tumor including the deep femoral vein and arterial bifurcation was done with an arterial reconstruction using a synthetic graft. Histopathological examination revealed an intravascular SS of the common femoral vein. The mainstay of curative therapy is complete surgical resection of all tumor manifestations with negative histological margins.

    Background Acute exacerbation of chronic obstructive pulmonary disease (COPD) is always associated with a high incidence and mortality. Because of the presence of some concomitant risk factors such as immobilization, bronchial superinfection, patients who are admitted for acute exacerbations of COPD are generally considered to be at moderate risk for the development of venous thromboembolism. In this study, we investigated the prevalence and the clinical manifestations of deep venous thrombosis (DVT) in patients with acute exacerbation of COPD.Methods From March 2007 to March 2009, 520 consecutive patients were included in this study. On admission, color Doppler ultrasound of lower extremities in all cases was performed for diagnosing DVT. Patients with DVT were compared with those without DVT from such aspects as demographics, symptoms, physical signs and risk factors.Results Among the 520 patients, DVT was found in 46 cases (9.7%). In patients with DVT, the duration of hospitalization was longer (P=0.01), and the mechanical ventilation requirement increased (P <0.001). Other indicators for patients with more possibility of DVT were immobility exceeding 3 days (P <0.001); pneumonia as concomitance (P=0.01); respiratory failure type Ⅱ (P=0.013); current smoking (P=0.001). Lower extremity pain was more common in DVT cases in comparison to those without DVT (34.8% vs. 15.2%, P=0.01 ).Conclusions The acute exacerbation of COPD patients, who were immobilized for over 3 days, complicated by pneumonia and had respiratory failure type Ⅱ, had a higher risk of DVT. In addition, DVT detection awareness should be increased in cases that had a lower extremity pain.

    Full Text Available Background: Deep venous thrombosis (DVT contributes significantly to the morbidity and mortality of neurosurgical patients; however, no data regarding lower extremity DVT in postoperative Chinese neurosurgical patients have been reported. Materials and Methods: From January 2012 to December 2013, 196 patients without preoperative DVT who underwent neurosurgical operations were evaluated by color Doppler ultrasonography and D-dimer level measurements on the 3rd, 7th, and 14th days after surgery. Follow-up clinical data were recorded to determine the incidence of lower extremity DVT in postoperative neurosurgical patients and to analyze related clinical features. First, a single factor analysis, Chi-square test, was used to select statistically significant factors. Then, a multivariate analysis, binary logistic regression analysis, was used to determine risk factors for lower extremity DVT in postoperative neurosurgical patients. Results: Lower extremity DVT occurred in 61 patients, and the incidence of DVT was 31.1% in the enrolled Chinese neurosurgical patients. The common symptoms of DVT were limb swelling and lower extremity pain as well as increased soft tissue tension. The common sites of venous involvement were the calf muscle and peroneal and posterior tibial veins. The single factor analysis showed statistically significant differences in DVT risk factors, including age, hypertension, smoking status, operation time, a bedridden or paralyzed state, the presence of a tumor, postoperative dehydration, and glucocorticoid treatment, between the two groups (P < 0.05. The binary logistic regression analysis showed that an age greater than 50 years, hypertension, a bedridden or paralyzed state, the presence of a tumor, and postoperative dehydration were risk factors for lower extremity DVT in postoperative neurosurgical patients. Conclusions: Lower extremity DVT was a common complication following craniotomy in the enrolled Chinese neurosurgical

    Computed Tomography Angiogram (CTA) has become a routine part of pre-operative assessment of vascular anatomy and design in perforator flaps. We conducted a retrospective cohort study of flap raised on the deep inferior epigastric system (DIES) at our institution in order to identify CTA signs that might predict venous congestion in these flaps. 98 consecutive patients who had 124 DIES flaps raised from 2008 to 2012 were studied. Of these 124 flaps, four (3.2%) developed venous congestion. Our results showed that a Superficial Inferior Epigastric Vein (SIEV) that is larger than the DIEV at origin is highly predictive of congestion (5.2 vs 3.5 mm, p = 0.007). The findings of an axial non-arborising superficial system (96.7% vs 0, p flap failure with patients, and contingency planning to augment venous drainage with the superficial system if required.

Binding of 99mTc-tirofiban to platelets was evaluated. Serum levels of unlabeled (a validated high performance liquid chromatography method and 99mTc-tirofiban after single intravenous injection were evaluated in male Wistar rats with or without induced DVT (femoral vein ligation model, and the rats were also subjected to whole body scintigraphy.Results: Tirofiban in vitro inhibits ADP-induced aggregation of human platelets in a dose- and concentration-dependent manner (10 nM to 2 µM, but only if it is added before ADP and not after ADP. 99mTc labeling did not affect the ability of tirofiban to bind to either human or rat platelets, nor did it affect tirofiban pharmacokinetics in intact rats or in animals with induced DVT.

    Full Text Available Abstract Background Few studies have evaluated patient-reported outcomes in connection with a primary event of deep venous thrombosis, partly due to a lack of disease-specific measures. The aim here was to develop a disease-specific health-related quality of life (HRQL measure, the deep venous thrombosis quality of life questionnaire (DVTQOL, for patients with recent exposition and treatment of proximal deep venous thrombosis. Methods A total of 121 consecutive outpatients (50 % males; mean age 61.2 ± 14 years treated with warfarin (Waran® for symptomatic proximal deep venous thrombosis were included in the study. Patients completed the SF-36, EQ-5D and the pilot version of the DVTQOL. Results Items having: high ceiling and floor effect, items with lower factor loadings than 0.50 and items loading in several factors were removed from the pilot version of DVTQOL. In addition, overlapping and redundant items identified by the Rasch analysis were excluded. The final DVTQOL questionnaire consists of 29 items composing six dimensions depicting problems with: emotional distress; symptoms (e.g. pain, swollen ankles, cramp, bruising; limitation in physical activity; hassle with coagulation monitoring; sleep disturbance; and dietary problems. The internal consistency reliability was high (alpha value ranged from 0.79 to 0.93. The relevant domains of the SF-36 and EQ-5D significantly correlated with DVTQOL, thereby confirming its construct validity. Conclusions The DVTQOL is a short and user-friendly instrument with good reliability and validity. Its test-retest reliability and responsiveness to change in clinical trials, however, must be explored.

    Full Text Available Objective: Pulmonary thromboembolism (PTE named due to migration of clots formed in systemic venous system to pulmonary vascular bed is a serious clinical table. After acute DVT, asymptomatic PTE is seen about 40-60% and this situation can not be discovered because of silent clinical course. In this study, we aimed to compare sensivity and spesifity of multi detector computerized tomography (MDCT, which is used extensively in recent years, with ventilation-perfusion (V/P scintigraphy which is used formerly for diagnosis of asymptomatic PTE developed after acute lower extremity DVT. Methods: The study was carried out 25 patients who were admitted to our clinic and treated for lower extremity acute DVT. Pregnants, and cases with recurrent DVT, presence of symptomatic PTE during admission, thrombosis extending to vena cava, and history of passed PTE were excluded from the study. DVTs in patients were diagnosed by color doppler, and confirmed by D-dimer test. After patients’s admission, V/P scintigraphy and MDCT were used to detects asymptomatic PTE at 1st and 8 th day of the admission. Results: D-dimer was measured as higher in 24 of 25 patients with asemptomatic PTE. Ten patients were diagnosed by MDCT. Development of asymptomatic PTE related to acute DVT was determined as 40%. Conclusion: In terms of diagnostic value, MDCT was found more useful than V/P scintigraphy.

    Full Text Available Abstract Background Deep venous thrombosis (DVT is an important complication in the peripartal and postpartal period. Methods We followed up prospectively the prevalence of DVT in 34720 prenatal mothers between June 2002 and July 2006 attending the antenatal clinics of two major hospitals in Mumbai, India. Thirty two women (0.1% presented for the first time with symptomatic DVT i.e. 17 in the first trimester, 6 in the second and 9 in the third trimester of pregnancy. Nine had history of fetal loss while in the remaining twenty three there was no history of fetal loss. Results The evaluation of both acquired and heritable thrombophilia showed a conglomeration of thrombophilia in this group when compared to 100 normal pregnant women who have given birth to at least one healthy baby with no history of fetal death, DVT or other obstetrical complications.

    OBJECTIVES: Post-thrombotic syndrome (PTS) is a complication of deep vein thrombosis (DVT) characterized by chronic pain, swelling and heaviness, and may result in ulceration. Elastic compression stockings (ECS) worn daily after DVT appear to reduce the incidence and severity of PTS. The aims of our study were to investigate practices and perceptions of DVT patients and physicians regarding the use of ECS after DVT. METHODS: Two surveys were conducted. The first was sent to 225 staff and trainee clinicians and the second was administered to 150 DVT patients. RESULTS: The results demonstrated that the majority of senior staff (75%) believed that ECS were effective in preventing PTS and in managing venous symptoms. However, this was in contrast with junior trainees (21%) (P < 0.05). This resulted in only 63% of patients being prescribed ECS post-DVT. There was a lack of consensus as regards the optimal timing of initiation of ECS, duration of therapy and compression strength. Nearly all DVT patients who were prescribed ECS purchased them, 74% wore them daily, and most (61%) reported that ECS relieved swelling and symptoms. Physicians correctly predicted the main reasons for non-compliance, but misjudged the scale of patient compliance with ECS. CONCLUSIONS: Our findings suggest that there is a lack of consensus among doctors regarding ECS use after DVT and widespread education regarding the latest evidence of the benefit of ECS after DVT.

    To evaluate the efficacy of an IVC filter implantation in the prevent of a pulmonary embolism (PE) during endovascular treatment for a deep venous thrombosis (DVT) of the lower extremities. We implanted IVC filters in 43 patients (22 females, 21 males, average age: 63 years) with DVT and who had undergone treatments including thrombolysis, aspiration and mechanical thrombectomy, as well as stent placement. We evaluated the incidence of PE by capturing the thrombus within the IVC filters, as well as the amount of captured thrombus. New developing PE or aggravating of PE in patients with existing PE was avoided in all patients. No thrombus was evident in the IVC filter of 19 (44%) of the patients, whereas any thrombus was captured in 24 (56%) of the patients. Small amounts of thrombus were captured in 10 patients, whereas large amounts of thrombus were captured in 14 patents within the IVC filter. We performed a retrieval of the IVC filters in 17 patients within an average period of 15.3 days (range 6-45 days). The captured incidence of migrated thrombus in the IVC filters was high in 56% of cases. As a result, PE was effectively prevented by IVC filters during the interventional treatment of DVT in the lower extremities.

    To evaluate the efficacy of endovascular management of lower extremity deep vein thrombosis (DVT) in patients with malignant disease. Between January 2002 and January 2008, six consecutive patients (5 male and 1 female, mean age-65 years) with lower extremity DVT and malignant disease underwent endovascular management. The duration of symptoms lasted 4-120 days (mean-31 days; 20 days or less in four patients and more than 20 days in two). A catheter-directed thrombolysis was performed via the ipsilateral popliteal vein or common femoral vein, used alone or combined with a percutaneous mechanical thrombectomy. Angioplasty or stent placement was performed in residual stenosis or occlusion of the vein. The follow-up period lasted 1-14 months (mean 7.6 months) and was performed via a color Doppler ultrasonography or computed tomographic venography. Technical success and relief from symptoms was achieved within two days was achieved in five patients. Minor hemorrhagic complications occurred in two cases: hematuria and a hematoma at the puncture site. Upon follow-up, a recurrent DVT occurred in three patients as well as a patent venous flow in two. One patient died within 1 month due to a metastatic mediastinal lymphadenopathy. Endovascular management of the lower extremity DVT is effective for quickly eliminating a thrombus, relieving symptoms, and decreasing hemorrhagic complications in patients with malignant disease.

    Fifty-six patients scheduled for total hip alloplasty were screened for deep venous thrombosis by means of 99mTc-plasmin scintimetry, 99mTc-plasmin scintigraphy and contact thermography. Investigations were performed on the seventh postoperative day, and a total of 112 legs were examined. Bilateral...... ascending phlebography was used as reference procedure, and the criteria for deep venous thrombosis were intraluminal filling defects at phlebography. Six patients developed unilateral deep venous thrombosis. All three screening procedures revealed many false positive and several false negative results....... The nosographic sensitivity/specificity was 33%/75% for scintimetry, 50%/91% for scintigraphy and 33%/87% for contact thermography, respectively. It is concluded that all three tests are of no value as screening methods for deep venous thrombosis following major elective hip surgery....

    Moraxella bovoculi is a recently described bacterium that is associated with infectious bovine keratoconjunctivitis (IBK) or "pinkeye" in cattle. In this study, closed circularized genomes were generated for seven M. bovoculi isolates: three that originated from the eyes of clinical IBK bovine cases and four from the deep nasopharynx of asymptomatic cattle. Isolates that originated from the eyes of IBK cases profoundly differed from those that originated from the nasopharynx of asymptomatic cattle in genome structure, gene content and polymorphism diversity and consequently placed into two distinct phylogenetic groups. These results suggest that there are genetically distinct strains of M. bovoculi that may not associate with IBK.

  16. 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.

    Objective: To assess coagulation function and ultrasound features after reteplase and recombinant streptokinase thrombolysis of lower extremity deep venous thrombosis. Methods:A total of 78 cases of patients with lower extremity deep venous thrombosis who were treated in our hospital were selected as research subjects and divided into observation group 39 cases and control group 39 cases according to different treatment regimens. Control group received recombinant streptokinase thrombolysis, observation group received reteplase thrombolysis, and then the effect of the two thrombolytic ways was evaluated by color Doppler ultrasonography and circulating blood test. Results:Ultrasound showed that complete recanalization rate of thrombus of observation group after treatment was higher than that of control group;plasma PT, APTT and TT values of observation group after thrombolysis were higher than those of control group, FIB, D-D, NO, ET, E-selectin, P-selectin, Hcy, CRP, IL-6, IL-8 and TNF-αvalues were lower than those of control group, and WBC, Nc and Mc cell number were less than those of control group. Conclusion:Reteplase for thrombolysis of lower extremity deep venous thrombosis has more distinguished effect on dissolving thrombus as well as optimizing body’s coagulation, inflammatory system state and other aspects, and is a more ideal thrombolytic drug.

  18. Deep venous thrombosis and pulmonary embolism. Part 1. Initial treatment: usually a low-molecular-weight heparin.

    Science.gov (United States)

    2013-04-01

    Patients with deep venous thrombosis are at a short-term risk of symptomatic or even life-threatening pulmonary embolism, and a long-term risk of post-thrombotic syndrome, characterised by lower-limb pain, varicose veins, oedema, and sometimes skin ulcers. What is the best choice of initial antithrombotic therapy following deep venous thrombosis or pulmonary embolism, in terms of mortality and short-term and long-term complications? How do the harm-benefit balances of the different options compare? To answer these questions, we reviewed the available literature using the standard Prescrire methodology. Unfractionated heparin has documented efficacy in reducing mortality and recurrent thromboembolic events in patients with pulmonary embolism or symptomatic proximal (above-knee) deep venous thrombosis. The authors of a systematic review selected 23 trials of low-molecular-weight heparin (LMWH) versus adjusted-dose unfractionated heparin in a total of 9587 patients. Deaths, recurrences and major bleeds were less frequent with LMWH than with unfractionated heparin. The results of other meta-analyses are similar, but all are undermined by a probable publication bias and methodological flaws. Compared to unfractionated heparin, LMWHs have the advantage of fixed-dose administration, once or twice daily, by subcutaneous injection. All available LMWHs seem to have similar efficacy. Those with the longest experience of use are enoxaparin, dalteparin and nadroparin. The harm-benefit balances of fondaparinux and rivaroxaban do not appear more favourable than that of an LMWH followed by an adjusted-dose vitamin K antagonist. A meta-analysis included 12 trials comparing thrombolysis with anticoagulation alone in 700 patients with deep venous thrombosis. Adding a thrombolytic drug did not reduce mortality or the incidence of pulmonary embolism, whereas it increased the incidence of bleeding. A meta-analysis of 13 trials failed to show that adding a thrombolytic drug to initial

    The Tempofilter II is a widely used temporary vena cava filter. Its unique design, which includes a long tethering catheter with a subcutaneous anchor, facilitates the deployment and retrieval of the device. Despite this, the Tempofi lter II has been used only in the inferior vena cava of patients with lower extremity deep venous thrombosis. In this article, we present a case of superior vena cava filtering using the Tempofilter II in patients with upper extremity deep venous thrombosis

  20. Detection of experimental pulmonary thrombosis and deep venous thrombosis by 99Tcm-DMP444

    International Nuclear Information System (INIS)

    Objective: To evaluate 99Tcm-dimethyl phthalate (DMP) 444 scintigraphy for detection of PE and deep venous thrombosis (DVT) in animal models. Methods: The experimental PE and DVT were induced in 5 dogs. Venous blood samples (1 ml) were collected at 30 s, 2 min, 3 min, 4 min, 5 min, 10 min, 15 min, 30 min, 60 min, 90 min and 120 min respectively after the tracer injection. The collected blood samples were weighed and counted for radioactivity in a γ-counter. The radioactivity was expressed as a percentage of the initial (30 s) activity. The blood clearance rate at each time point was obtained. The images of lungs and legs were acquired at 15, 30, 60, 90 and 120 min after the injection. ROI was drawn on PE, DVT, lung, contralateral femoral vein and lateral thigh for calculating the radioactivity ratios of PE/lung (P/L), DVT/blood (D/B) and DVT/muscle (D/M). PE and DVT were removed, weighed and counted for radioactivity ex vivo to determine the % ID/g. Data at different time points were compared by one-way repeated measures analysis of variance. Results: Blood clearance rate of 99Tcm-DMP444 was (65.4 ± 3.9) % at 120 min after the injection. The radioactivity ratios of PE and DVT increased over time, and the radioactivity ratios of P/L, D/B and D/M increased from 2.41 ±0.28, 1.67 ±0.33, 2.20 ±0.14 at 15 min to 3.96 ± 0.64, 2.56 ± 0.57, 3.90 ± 0.95 at 120 min, after the injection respectively (F=14.57, 7.68, 9.37, all P<0.05). The % ID/g of PE and DVT was 0.085 ± 0.023 and 0.054 ± 0.018 respectively. Conclusion: 99Tcm-DMP444 may become a potential radiopharmaceutical agent for noninvasively detecting PE and DVT. (authors)

    Objective: To assess whether light reflection rheography testing is affected by the changes that occur in the deep venous system of the lower limb in pregnancy and the puerperium. Methods: Twenty five women with a singleton pregnancy were recruited to undergo duplex Doppler ultrasound examinations of the common femoral vein to measure the vessel diameter and the blood flow velocity. Light reflection rheography testing was subsequently performed and the rate of venous emptying in the lower limb calculated. Serial measurements using both techniques were made at 15, 28, 36 weeks, and term gestation and at 2 days and 6 weeks postpartum. Results: Duplex Doppler ultrasound confirmed that there is progressive dilatation of the deep venous system in pregnancy, which reaches a maximum at term and reverses after delivery. There is an accompanying reduction in blood flow velocity, which reaches a nadir at term and increases after delivery. The rate of venous emptying as measured by light reflection rheography decreases with increasing gestation, but did not fall to a level consistent with venous occlusion by a deep venous thrombosis. Conclusions: Light reflection rheography has been shown to provide reliable results in pregnancy and the puerperium. Therefore, it is a potential tool for screening for deep venous thrombosis in this population.

    Full Text Available Chronic traumatic arteriovenous fistula (AVF commonly results from an unrecognized vascular injury. In this report, there were two cases of chronic traumatic AVF of the legs with a long history of stab (case 1 and shotgun wounds (case 2. Both cases presented with varicose veins together with hyperpigmentation around the ankle of the affected leg. Angiograms showed a single large AVF in case 1, whereas, in case 2, there was a single large AVF together with multiple small AVFs. In both cases large venous aneurysm was found next to a large AVF. An open surgical AVF closure for the large AVF was performed in case 1 successfully, but patient developed acute deep vein thrombosis (DVT in a large venous aneurysm. In the second case, in order to prevent DVT, only closure of the large AVF was performed, which preserved arterial flow into the venous aneurysm. Case 2 did not have acute DVT. This report raised the concern about acute DVTs in venous aneurysms following the closure of chronic traumatic AVF in terms of prevention. Also chronic traumatic AVF is commonly due to misdiagnosis in the initial treatment, so complete and serial physical examinations in penetrating vascular injury patients are of paramount importance.

    Aim The aim of this study was to investigate the possibility of using 99mtechnetium (99mTc)-labeled tirofiban (a reversible antagonist of glycoprotein IIb/IIIa) for detection of deep venous thrombosis (DVT) in rats without causing an antiplatelet effect. Methods The ability of in vitro tirofiban to inhibit adenosine 5′-diphosphate (ADP)-induced platelet aggregation was evaluated using optical aggregometer. Binding of 99mTc-tirofiban to platelets was evaluated. Serum levels of unlabeled (a validated high performance liquid chromatography method) and 99mTc-tirofiban after single intravenous injection were evaluated in male Wistar rats with or without induced DVT (femoral vein ligation model), and the rats were also subjected to whole body scintigraphy. Results Tirofiban in vitro inhibits ADP-induced aggregation of human platelets in a dose- and concentration-dependent manner (10 nM to 2 μM), but only if it is added before ADP and not after ADP. 99mTc labeling did not affect the ability of tirofiban to bind to either human or rat platelets, nor did it affect tirofiban pharmacokinetics in intact rats or in animals with induced DVT. When 99mTc-tirofiban was injected to rats after induction of DVT, at a molar dose lower than the one showing only a weak antiaggregatory effect in vitro, whole body scintigraphy indicated localization of 99mTc-tirofiban around the place of the induced DVT. Conclusion 99mTc labeling of tirofiban does not affect its ability to bind to glycoprotein IIb/IIIa or its in vivo pharmacokinetics in rats, either intact or with DVT. A low, nonantiaggregatory dose of 99mTc-tirofiban may be used to visualize DVT at an early stage. PMID:27713618

    Deep venous thrombosis (DVT) is a common surgical complication in cancer patients and evidence that inflammation plays a role in the occurrence of DVT is increasing. We studied a population of cancer patients with abdominal malignancies with the aim of investigating whether the levels of circulating inflammatory cytokines were associated with postoperative DVT, and to determine the levels in DVT diagnoses. The serum levels of C-reactive protein (CRP), interleukins (IL)-6 and IL-10, nuclear transcription factor-κB (NF-κB) and E-selectin (E-Sel) were determined in 120 individuals, who were divided into 3 groups: healthy controls, patients with and patients without DVT after surgery for an abdominal malignancy. Data were analyzed by ANOVA, Dunnet's T3 test, chi-square test, and univariate and multivariate logistic regression as needed. The CRP, IL-6, NF-κB, and E-Sel levels in patients with DVT were significantly higher than those in the other groups (P<0.05). The IL-10 level was higher in patients with DVT than in controls but lower than in patients without DVT. Univariate analysis revealed that CRP, IL-6, NF-κB, and E-Sel were statistically associated with the risk of DVT (OR=1.98, P=0.002; OR=1.17, P=0.000; OR=1.03, P=0.042; and OR=1.38, P=0.003; respectively), whereas IL-10 had a protective effect (OR=0.94, P=0.011). Multivariate analysis showed that E-Sel was an independent risk factor (OR=1.41, P=0.000). Thus, this study indicated that an increased serum level of E-Sel was associated with increased DVT risk in postoperative patients with abdominal malignancy, indicating that E-Sel may be a useful predictor of diagnosis of DVT.

    With an incidence of 0.7% inhabitants per year, acute deep venous thrombosis (DVT) is a common occurrence (20). Its incidence in the upper extremities, however, is not as precisely known; the literature reports that 1% to 10% of all DVT cases involve the upper limbs. Acute DVT of upper limb is mainly iatro-genic following interventions like implantation of pacemakers or central venous catheters, and is more likely to occur in obese patients or those with malignant diseases. Life-threatening pulmonary embolism (PE) may occur if acute DVT remains undetected. The presented case report demonstrates the feasibility of {sup 9}9mTc-apcitide scintigraphy for diagnosis of acute DVT of the upper limb and exclusion of PE in a single examination.

    Full Text Available IVIg therapy has potentially been related to arterial and venous therapy. We performed an Ovid review focusing on IVIg and thrombotic events. While a few case reports were reviewed case series and case control studies were particularly reviewed in relation to thrombotic events. Outcomes demonstrate a correlation between underlying cardiovascular risk factors with predominately arterial events which typically occurred within 4–24 hours of infusion. While venous events occurred less commonly they were associated with traditional risk factors and occurred later, typically, 1–7 days following infusion of IVIg. Potential causation of thrombotic events was discussed.

Methods: Clinical data of 8 patients with postpartum deep vein thrombosis of lower extremities were analyzed and summarized in our department from January, 2006 to December, 2010. Result: After the treatment, the symptoms and signs of all the cases were relieved. Ultrasound showed that deep venous thrombosis was disappeared. No one pulmonary embolism occurred. Conclusion: Factors which induced postpartum deep venous thrombosis of lower extremities are related to blood hypercoagulability, slow blood flow and venous endothelium injury, and so on. The indications of cesarean section should be controlled to reduce the rate of cesarean section. Early postpartum activities are taken to accelerate the venous refluence, which can prevent deep venous thrombosis of lower extremities.

    The authors analysed the results of examination and treatment of a total of 102 patients presenting with iliofemoral venous thrombosis. During treatment, ultrasonographic duplex scanning was used to determine the localization of the proximal margin of thrombotic masses, the time of appearing of the first signs of recanalization, its degree at various levels of the deep venous system, as well as alteration in velocity of the venous blood flow in the deep veins of the lower limbs. The dynamics of clinical symptoms was assessed by the visual analogue scale. Clinical and instrumental examination was performed on day 10, and then 1, 3, 6 and 12 months after the beginning of treatment. The patients were subdivided into three groups. Group One comprised 38 patients receiving therapy with low-molecular-weight heparin (enoxaprin) followed by switching to indirect anticoagulants (warfarin) combined with venotonics (original highly-purified diosmin 600 mg once daily). Group Two was composed of 33 patients receiving rivaroxaban at a dose of 15 mg twice daily for 3 weeks, followed by 20 mg once daily. Group Tree patients (n=31) were also given rivaroxaban according to the above-described standard regimen but in combination with venotonics (original highly-purified diosmin 600 mg once daily). The obtained findings showed that prescribing rivaroxaban to patients from the first day of the disease made it possible to considerably improve and accelerate the processes of restoration of patency of deep veins of lower extremities as compared with the patients taking vitamin K antagonists (warfarin). In patients receiving rivaroxaban, there were no cases of residual thrombotic occlusions of the major veins, and recanalization in three fourths of patients was assessed as good and in the remaining third as moderate. In the warfarin group, occlusion in the iliac veins was noted to persist persisted in 13% of patients, with good recanalization observed only in half of the patients. Addition

    2012-01-01

    Full Text Available Background: Genetic variation in multiple genes associated with hemostasis and thrombosis is well documented to impact the rates of future venous thromboembolism; in addition, trauma and orthopedic surgery in lower limb and immobilization are important factors in increasing the incidence of thrombosis. Gene mutation can be predisposing factor for thrombosis in traumatic patients under anti-coagulant agent prophylaxis. The aim of this study is to evaluate the different gene mutations in these patients. Materials and Methods: In this cross-sectional descriptive study, the sample consisted of 53 patients with deep venous thrombosis (DVT and 32 traumatic patients without thrombosis as the control group. Two groups matched together according to sex, age, weight, and medications. DNA analysis for mutation of multivariate of genes in thrombosis was studied. Results: Regarding gene variations, there was statistically significant difference only in Prothrombin (Factor II, G20210A between the patients with thrombosis and control group (P = 0.01. But, there was no difference between two groups considering other gene mutations. Mutation of Prothrombin gene (G20210A was a predictive factor for thrombosis with odds ratio of 1.1 (CI 0.3-1.9. Conclusion: According to the outcomes resulted from this study, genetic mutation in Prothrombin (Factor II [G20210A] is one of the most important genetic variations involved in traumatic patients with DVT despite prophylaxis. Genetic mutation in Prothrombin appears to be predisposing factor for thrombosis associated with trauma.

    Full Text Available The diagnosis of deep venous thrombosis (DVT may be challenging due to the inaccuracy of clinical assessment and diversity of diagnostic tests. On one hand, missed diagnosis may result in life-threatening conditions. On the other hand, unnecessary treatment may lead to serious complications. As a result of an initiative of the Ministry of Health of the Kingdom of Saudi Arabia (KSA, an expert panel led by the Saudi Association for Venous Thrombo-Embolism (SAVTE; a subsidiary of the Saudi Thoracic Society with the methodological support of the McMaster University Working Group, produced this clinical practice guideline to assist healthcare providers in evidence-based clinical decision-making for the diagnosis of a suspected first DVT of the lower extremity. Twenty-four questions were identified and corresponding recommendations were made following the Grading of Recommendations, Assessment, Development and Evaluation (GRADE approach. These recommendations included assessing the clinical probability of DVT using Wells criteria before requesting any test and undergoing a sequential diagnostic evaluation, mainly using highly sensitive D-dimer by enzyme-linked immunosorbent assay (ELISA and compression ultrasound. Although venography is the reference standard test for the diagnosis of DVT, its use was not recommended.

    The purpose of this article is to report long-term follow-up of improved external vulvuloplasty, intravenous laser photocoagulation and local sclerotherapy treatment of primary deep venous valvular insufficiency in eight hundred and seventy-two patients from Nov. 2000 to May 2006. Patients were evaluated clinically and with duplex ultrasound at 1, 3, and 12 months, and yearly thereafter until the fifth year to assess treatment efficacy and adverse reactions. Successful occlusion of the great saphenous vein and absence of deep vein reflux on color Doppler imaging, were noted in 956 limbs of 852 cases( 1 month follow-up), 946 limbs of 842 cases (6 month to 1 year follow-up), 717 of 626 (1~2 year follow-up), 501 of 417 (2~3 year follow-up), 352 of 296 (3~5year follow-up), 142 of 106 (5 year follow-up) after initial treatment. The cumulative total number of recurrence of reflux was fifteen cases. The respective competence rate was 95.18%, 96.23%, 94.23%, 95.25%, 94.23% and 94.12%. Of note, all recurrence occurred before 9 months, with the majority noted before 3 months. Bruising was noted in 0.7% of patients, tightness along the course of treated vein in 1.0% of limbs. There have been no paresthesia of cases, skin burns and deep vein thrombosis.

    An 83-year-old obese woman with a 60-pack-year smoking history was referred for evaluation of an abnormal chest radiograph [chest x-ray (CXR)]. Her past medical history was significant for recurrent deep venous thrombosis without any predisposing factors. CXR showed a large mass in the right mid lung and another nodule at the right apex, highly suspicious for a neoplastic process. These were not present on a CXR from 2 years earlier. An fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) scan revealed that all lesions were strongly FDG-avid. Six CT-guided core-needle lung biopsy specimens were obtained from the lung mass and all contained dense, lamellar, or "ropy" keloid-like collagen bundles arranged in a haphazard pattern. The biopsy specimens lacked significant necrosis and granulomas. Congo red stain with polarization was also negative for amyloid. The diagnosis of pulmonary hyalinizing granuloma (PHG) was made. A complete hypercoagulable workup was performed but no underlying abnormalities were found, including a negative lupus anticoagulant and malignancy workup. The patient was maintained on warfarin and followed with serial CT scans for 1 year, with spontaneous regression in the lung mass. The case is unique as it is the first case that reports an association of PHG with recurrent deep venous thrombosis in the absence of autoimmune or procoagulant factors and emphasizes the need for life-long anticoagulation in such scenarios. Also, we report the FDG-avid PET scan findings here that are novel for this disease in adults and add PHG to the list of diseases causing false-positive PET scans when malignancy is suspected.

    Both pulmonary arterial and peripheral venous sides of venous thromboembolism (VTE) can now be efficiently and safely investigated by multi-detector CT (MDCT) at the same time by a combined CT angiography/CT venography protocol. In the emergency setting, the use of such a single test for patients suspected of suffering from VTE on a clinical grounds may considerably shorten and simplify diagnostic algorithms. The selection of patients to be submitted to MDCT must follow well-established clinical prediction rules in order to avoid generalized referral to CT on a generic clinical suspicion basis and excessive population exposure to increased ionizing radiation dose, especially in young patients. Clinical and anatomical wide-panoramic capabilities of MDCT allow identification of underlying disease that may explain patients' symptoms in a large number of cases in which VTE is not manifest. The analysis of MDCT additional findings on cardiopulmonary status and total thrombus burden can lead to better prognostic stratification of patients and influence therapeutic options. Some controversial points such as optimal examination parameters, clinical significance of subsegmentary emboli, CT pitfalls and/or possible falsely positive diagnoses, and outcome of untreated patients in which VTE has been excluded by MDCT without additional testing, must of course be taken into careful consideration before the definite role of comprehensive MDCT VTE 'one-stop-shop' diagnosis in everyday clinical practice can be ascertained.

    . Sixty-eight percent of the catheters were infected: 72% of them were from Group 1 and 28% from Group 2 (asymptomatic patients. Systemic infection was diagnosed in 70% of the patients from Group 1. Positive blood culture was found in 17% of the patients from Group 2. The microorganisms found were: Staphylococcus sp. (48%, Candida sp. (21%, Enterococcus faecalis (16%, Pseudomonas aerurginosa (10% and Proteus sp. (5%. CONCLUSION: Central venous catheter infection is common in hospitalized asymptomatic patients. Patients receiving total parenteral nutrition are most frequently infected with Candida sp. Therefore, the creation of barriers that block colonization in the central venous catheter is essential to decrease the morbidity and mortality among patients that depend on total parenteral nutrition.

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

    Congenital anomalies of the inferior vena cava (IVC) are increasingly recognized with CT and venography techniques. Although many patients with IVC anomalies are asymptomatic, recent studies have suggested an association with venous thromboembolism. We report the case of a 62-year-old woman with extensive venous clot involving the infrarenal segment of a duplicated left IVC who underwent pharmacomechanical thrombectomy and tissue plasminogen activator catheter-directed thrombolysis with complete deep venous thrombosis resolution. To our knowledge this is the first reported case in the English literature of the use of a Trellis thrombectomy catheter in the setting of duplicated IVC.

    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.

    To investigate the validity of the 100 kVp setting in CT venography (CTV) in the diagnosis of deep vein thrombosis (DVT), and to evaluate the feasibility of reducing the amount of administered iodine in this setting. After receiving the contrast medium (CM) of 2.0 mL/kg, 88 patients underwent CTV of the pelvis and lower extremities by using one of four protocols: Group A, 120 kVp setting and 370 mgI/mL CM; group B, 120 kVp and 300 mgI/mL; group C, 100 kVp and 370 mgI/mL; group D, 100 kVp and 300 mgI/mL. The groups were evaluated for venous attenuation, vein-to-muscle contrast-to-noise ratio (CNR{sub VEIN}), DVT-to-vein contrast-to-noise ratio (CNR{sub DVT}), and subjective degree of venous enhancement and image quality. Venous attenuation and CNR{sub VEIN} were significantly higher in group C (144.3 Hounsfield unit [HU] and 11.9), but there was no significant difference between group A (118.0 HU and 8.2) and D (122.4 HU and 7.9). The attenuation value of DVT was not significantly different among the four groups, and group C had a higher absolute CNR{sub DVT} than the other groups. The overall diagnostic image quality and venous enhancement were significantly higher in group C, but there was no difference between groups A and D. The 100 kVp setting in CTV substantially help improve venous enhancement and CNR{sub VEIN}. Furthermore, it enables to reduce the amount of administered iodine while maintaining venous attenuation, as compared with the 120 kVp setting.

    A 22-year-old morbidly obese, nonpregnant woman presented with left ileofemoral deep vein thrombosis (DVT) presenting as low back pain and bilateral, left greater than right, leg swelling and pain for 2 days. While on heparin, she developed compartment syndrome in her left leg and had evidence of dead muscle tissue at the time of fasciotomy. Three options exist for treatment of ileofemoral DVT: catheter-directed thrombolysis (CDT), CDT plus pharmacomechanical thrombolysis or percutaneous mechanical thrombectomy, and surgical thrombectomy. Catheter-directed thrombolysis alone or in conjunction with pharmacomechanical thrombolysis in patients with low risk of bleeding has shown significant lysis of occlusion in 79% of patients with ileofemoral DVT with relatively low complication rates. Surgical thrombectomy and fasciotomy have not proven to be as effective but are appropriate alternatives if CDT is not available. Standard anticoagulation alone is likely not a sufficient treatment for ileofemoral DVT. Other therapies including CDT, CDT plus pharmacomechanical thrombolysis or percutaneous mechanical thrombectomy, or surgical thrombectomy to address lysis of the clot should be attempted first or in conjunction with anticoagulation for appropriate patients. Catheter-directed thrombolysis with or without pharmacomechanical thrombolysis is the preferred initial treatment.

    This study was undertaken to investigate the sequence of alterations in the venous blood flow to have occurred within the time frame of one year after sustained acute thrombosis of the lower-limb deep veins, which was carried out using the standard technique of ultrasonographic duplex scanning. A total of thirty-two 24-to-62-year-old patients presenting with newly onset acute phlebothrombosis were followed up. All the patients were sequentially examined at 2 days, 3 weeks, 3 months, 6 months and 12 months after the manifestation of the initial clinical signs of the disease. Amongst the parameters to determine were the patency of the deep veins and the condition of the valvular apparatus of the deep, superficial and communicant veins. According to the obtained findings, it was as early as at the first stage of the phlebohaemodynamic alterations after the endured thrombosis, i. e., during the acute period of the disease, that seven (21.9%) patients were found to have developed valvular insufficiency of the communicant veins of the cms, manifesting itself in the formation of a horizontal veno-venous reflux, and 6 months later, these events were observed to have occurred in all the patients examined (100%). Afterwards, the second stage of the phlebohaemodynamic alterations was, simultaneously with the process of recanalization of the thrombotic masses in the deep veins, specifically characterized by the formation of valvular insufficiency of the latter, manifesting itself in the form of the development of a deep vertical veno-venous reflux, which was revealed at month six after the onset of the disease in 56.3% of the examined subjects, to be then observed after 12 months in 93.8% of the patients involved. Recanalization of thrombotic masses was noted to commence 3 months after the onset of thrombosis in twelve (37.5%) patients, and after 12 months it was seen to ensue in all the patients (100%), eventually ending in complete restoration of the patency of the affected

    We investigated the association between haplotypes of fibrinogen alpha (FGA), beta (FGB), and gamma (FGG), total fibrinogen levels, fibrinogen gamma' (gammaA/gamma' plus gamma'/gamma') levels, and risk for deep venous thrombosis. In a population-based case-control study, the Leiden Thrombophilia Study, we typed 15 haplotype-tagging single nucleotide polymorphisms (htSNPs) in this gene cluster. None of these haplotypes was associated with total fibrinogen levels. In each gene, one haplotype increased the thrombosis risk approximately 2-fold. After adjustment for linkage disequilibrium between the genes, only FGG-H2 homozygosity remained associated with risk (odds ratio [OR], 2.4; 95% confidence interval [95% CI], 1.5-3.9). FGG-H2 was also associated with reduced fibrinogen gamma' levels and reduced ratios of fibrinogen gamma' to total fibrinogen. Multivariate analysis showed that reduced fibrinogen gamma' levels and elevated total fibrinogen levels were both associated with an increased risk for thrombosis, even after adjustment for FGG-H2. A reduced fibrinogen gamma' to total fibrinogen ratio (less than 0.69) also increased the risk (OR, 2.4; 95% CI, 1.7-3.5). We propose that FGG-H2 influences thrombosis risk through htSNP 10034C/T [rs2066865] by strengthening the consensus of a CstF site and thus favoring the formation of gammaA chain above that of gamma' chain. Fibrinogen gamma' contains a unique high-affinity, nonsubstrate binding site for thrombin, which seems critical for the expression of the antithrombin activity that develops during fibrin formation (antithrombin 1).

    Full Text Available Introduction: Deep venous thrombosis (DVT is thought to be less common in Asians than in Caucasian population. The incidence of DVT in high-risk groups, especially the neurosurgical (NS patients, has not been well studied. This leaves no firm basis for the start of early prophylactic anticoagulation within first 5 postoperative days in Indian NS patients. This is a prospective observational study to determine the early occurrence of DVT in the NS patients. Patients and Methods: We screened 137 consecutive high-risk NS patients based on inclusion and exclusion criteria. The femoral veins were screened using Doppler ultrasound on day 1, 3, and 5 of admission into the NS Intensive Care Unit (ICU at tertiary center from South India. Results: Among 2887 admissions to NICU 147 patients met inclusion criteria. One hundred thirty seven were screened for DVT. There was a 4.3% (6/137 incidence of DVT with none of the six patients having signs or symptoms of pulmonary embolism. Among the risk factors studied, there was a significant association with femoral catheterization and a probable association with weakness/paraparesis/paraplegia. The mortality in the study group was 10.8% with none attributable to DVT or pulmonary embolism. Conclusion: There is a low incidence of DVT among the high risk neurosurgical population evaluated within the first 5 days of admission to NICU, limiting the need for early chemical thrombo-prophylaxis in these patients. With strict protocols for mechanical prophylaxis with passive leg exercise, early mobilization and serial femoral Doppler screening, heparin anticoagulation can be restricted within the first 5 days of ICU admission in high risk patients.

    Objective:To observe the effect of low molecular weight heparin in combined with Shuxuetong in preventing the post-traumatic deep venous thrombosis (DVT).Methods:A total of 120 patients with post-traumatic DVT who were admitted in our hospital from February, 2014 to February, 2015 were included in the study and divided into the treatment group and the control group with 60 cases in each group according to different treatment protocols. The patients in the treatment group were given subcutaneous injection of low molecular weight heparin calcium and intravenous drip of Shuxuetong, while the patients in the control group were only given subcutaneous injection of low molecular weight heparin calcium. The changes of swelling degrees and coagulation indicators of the affected limb before and after treatment, and the clinical efficacy in the two groups were compared.Results:The total effective rate in the treatment group was significantly higher than that in the control group. The mean range of the perimeter 15cm above and below the bilateral knee joints after treatment in the treatment group was significantly lower than that in the control group. The shrinking rate of the mean range of the perimeter of the bilateral limbs in the treatment group was significantly higher than that in the control group. The comparison of PT, APTT, FIB, and INR before treatment between the two groups was not statistically significant. PT, APTT, and INR after treatment in the treatment group were significantly higher than those in the control group, while FIB was significantly lower than that in the control group.Conclusions:The low molecular weight heparin in combined with Shuxuetong can effectively prevent the post-traumatic DVT, with no requirement of monitoring of the bleeding tendency and safety.

    Detection of acute deep venous thrombosis (DVT) in patients presenting with clinical symptoms suggesting DVT and pulmonary embolism (PE) with {sup 99m}Tc-apcitide, a synthetic polypeptide, binding to glycoprotein IIb/IIIa receptors expressed on activated platelets is the objective of the study. Nineteen patients (11 males, eight females) received within 24h after admission to the hospital a mean of 841MBq (range 667 to 1,080) {sup 99m}Tc-apcitide i.v. followed by planar recordings 10, 60, and 120min after injection. Images were compared to the results of compression ultrasonography and/or phlebography. Patients with clinically suspected PE underwent spiral computed tomography or lung perfusion scans. {sup 99m}Tc-apcitide scintigraphy showed acute clot formation in 14 out of 16 patients where the other imaging modalities suggested DVT. Positive scintigraphic results were seen up to 17days after the onset of clinical symptoms. In three out of three patients without any proof of DVT, {sup 99m}Tc-apcitide scintigraphy was truly negative. Glycoprotein receptor imaging showed only one segmental PE in six patients with imaging-proven subsegmental (N = 3) or segmental PE (N = 3). {sup 99m}Tc-apcitide scintigraphy may be an easy and promising tool for the detection of acute clot formation in patients with DVT up to 17days after the onset of clinical symptoms with a sensitivity of 87% and a specificity of 100%. However, it failed to demonstrate PE in 83% of examined patients with proven PE. (orig.)

    Chronic venous disease is a common condition with clinical signs and symptoms ranging from spider veins, to varicose veins, to active venous ulceration. Both superficial and deep venous dysfunction may be implicated in the development of this disease. Socio-economic factors are shaping our population, with increasing age and body mass index resulting in significant pressure on healthcare systems worldwide. These risk factors also lead to an increased risk of developing superficial and/or deep venous insufficiency, increasing disease prevalence and morbidity. In this chapter, the authors review the current and future burden of chronic venous disease from an epidemiological, quality of life and economic perspective. PMID:26916773

    To assess the CT findings of acute deep venous thrombosis (DVT) in a lower extremity prior to catheter-directed thrombolysis, and to evaluate their relevance to the patency of an iliac venous stent placed with the help of CT after catheter-directed thrombolysis of DVT. Fourteen patients [M:F=3:11; age, 33-68 (mean, 50.1) years] with acute symptomatic DVD of a lower extremity underwent CT before and after catheter-directed thrombolysis using an iliac venous stent. The mean duration of clinical symptoms was 5.0 (range, 1-14 days. The CT findings prior to thrombolysis were evaluated in terms of their anatomic cause and the extent of the thrombus, and in all patients, the patency of the iliac venous stent was assessed at CT performed during a follow-up period lasting 6-31 (mean, 18.9) months. All patients were assigned to the patent stent group (n=9) or the occluded stent group (n=5). In the former, the anatomic cause of patency included typical iliac vein compression (May-Thurner syndrome) (n=9), and a relatively short segmental thrombus occurring between the common iliac and the popliteal vein (n=8). Thrombi occurred in the iliac vein (n=3), between the common iliac and the femoral vein (n=3), and between the common iliac and the popliteal vein (n=2). In one case, a relatively long segmental thrombus occurred between the common iliac vein and the calf vein. In the occluded stent group, anatomic causes included atypical iliac vein compression (n=3) and a relatively long segmental thrombus between the common iliac and the calf vein (n=4). Typical iliac vein compression (May-Thurner syndrome) occurred in two cases, and a relatively short segmental thrombus between the external iliac and the common femoral vein in one. Factors which can affect the patency of an iliac venous stent positioned after catheter-directed thrombolysis are the anatomic cause of the stenosis, and the extent of a thrombus revealed at CT of acute DVT and occurring in a lower extremity prior to

    Full Text Available Introduction In patients with pulmonary thromboembolism it is clinical to suspect the disease, establish the diagnosis and initiate anticoagulation treatment as early as possible in order to prevent relapses, which may be fatal. Deep venous thrombosis of lower extremities is the most common site of origin, which initially may remain obscure. Case report Two weeks prior to admission the patient had right-sided chest pain accompanied with dyspnea, interpreted and treated as pleuropneumonia. Pulmonary thromboembolism was suspected due to clinical symptoms, chest X-ray, elevated enzyme levels findings, blood gas analysis with hypoxemia and ECG with right heart overload. The diagnosis of pulmonary thromboembolism confirmed by lung scintigraphy presented with perfusion defects. After twenty days of heparin therapy, the patient developed left leg edema. Ultrasound screening confirmed bilateral iliac-femoral popliteal vein thrombosis of iliacofemoropopliteal veins bilaterally. Phlebography performed via jugular vein disclosed thrombotic material in the right common iliac vein, as well as in the vena cava inferior. In the course of the procedure vena cava filter has been placed. Discussion Although the patient was receiving anticoagulation heparin therapy, he developed pulmonary thromboembolism relapse and deep venous thrombosis. In our patient, vena cava filter placement was aimed at preventing pulmonary thromboembolism relapse. Since a deficit of S protein was also established, the patient is unfortunately likely to develop thrombosis at other sites as well. Conclusion In our patient pulmonary thromboembolism was a consequence of deep venous thrombosis, and the diagnosis was established by ultrasound screening of the lower extremities and confirmed by phlebography. During phlebography vena cava filter was placed in order to prevent pulmonary thromboembolism.

    Full Text Available Background: Deep venous thrombosis (DVT is a common complication of arthroplasty in old patients. We analyzed risk factors for lower-limb DVT after arthroplasty in patients aged over 70 years to determine controllable risk factors. Methods: This was a retrospective study of 1,025 patients aged >70 years treated with knee arthroplasty at our hospital between January 2009 and December 2013. Of 1,025 patients, 175 had postoperative lower-limb DVT. We compared medical history, body mass index (BMI, ambulatory blood pressure, preoperative and postoperative fasting blood glucose (FBG, preoperative blood total cholesterol, triglyceride, high- and low-density lipoprotein cholesterol, and preoperative homocysteine (Hcy between thrombus and non-thrombus groups. B-mode ultrasonography was used to detect lower-limb DVT before the operation and 7 days after the operation in all patients. Logistic regression analysis was used to determine risk factors for DVT. Results: Incidence of diabetes (P = 0.014, BMI (P = 0.003, preoperative FBG (P = 0.004, postoperative FBG (P = 0.012, and preoperative Hcy (P < 0.001 were significantly higher in the thrombus group. A significantly greater proportion of patients in the non-thrombus group had early postoperative activity (P < 0.001 and used a foot pump (P < 0.001. Operative duration was significantly longer in the thrombus group (P = 0.012. Within the thrombus group, significantly more patients had bilateral than unilateral knee arthroplasty (P < 0.01. Multivariate logistic analysis revealed BMI, preoperative Hcy, postoperative FBG, long operative duration, bilateral knee arthroplasty, and time to the activity after the operation to be predictive factors of DVT. At 6-month follow-up of the thrombus group, 4.7% of patients had pulmonary embolism and 18.8% had recurrent DVT; there were no deaths. Conclusions: Obesity, inactivity after operation, elevated preoperative Hcy and postoperative FBG, long operative duration, and

  5. Detection of deep venous thrombosis in an experimental animal model using radioactive labelled tirofiban GPIIb/IIIa inhibitor

    International Nuclear Information System (INIS)

    Detection of acute deep venous thrombosis (DVT), including biochemical information on thrombus formation, is one of the most important issues in clinical nuclear medicine. Thus, development of radiolabelled small peptide or peptidomimetic ligands that can bind platelets and their specific expressed receptor have been suggested as a new approach to detect clot location and, more essentially, determine the age and morphology of the evolving thrombus. This new approach has focused on the use of a series of radiolabelled platelet GPIIb/IIIa receptor antagonists. Tirofiban N-(butylsulfonyl)- 4-O-(4-(4-piperidyl)-L-tyrosine is a non-peptide tyrosine derivate. The aim of the study was to introduce radioactive labelled tirofiban as a specific imaging agent for acute DVT. Iodine-125-tirofiban labelling was performed using the Iodo-gen method with a >95% yield. Technetium-99-tirofiban labelling in the presence of a stannous reducing agent was obtained with a >95% yield. Both labelled preparations have a fast blood clearance in the normal rat model (without induced thrombosis). More than 80% of the injected dose was eliminated from the circulation in the first hour after injection. Biodistribution and visualization of the labelled molecule was carried out using an experimental model of thrombosis in the male Wistar rat. Planar images were obtained 30 min and 60 min after application of 2-6 x 106 counts/min 99mTc-tirofiban, as well as 2 h and 24 h after application of 1.6-2.1 x 106 counts/min in the rat's tail vein. Sensitivity and specificity were determined using the ratio 'left leg positive for DVT' and 'right leg negative for DVT'. The obtained ratio was 1.76 after 1 h, 1.99 after 3 h and 2.06 after 24 h in the case of iodine labelled tirofiban, and 1.54 after 30 min and 5.04 after 60 min with 99mTc-tirofiban. These values were considered as positive in the detection of acute DVT. The results from experimental studies show that radiolabelled tirofiban could be helpful in

    Background Deep venous thrombosis (DVT) can result in pulmonary embolism, a fatal complication that is due to the dislodgement and movement of a blood clot (thrombus) from a limb into the lungs. Genetic risk factors related to DVT development include mutations in coagulation proteins, especially the endothelial protein C receptor (EPCR), a component of the anticoaguiation protein C (PC) pathway. The objective of the present study was to analyze the relationship between the 6936A/G polymorphism in the EPCR gene and the occurrence of DVT.Methods This study involved 65 patients with DVT and 71 age- and gender-matched healthy controls. Peripheral blood samples were collected from all subjects. Plasma levels of soluble EPCR (sEPCR) were measured by enzyme-linked immunosorbent assay. Genomic DNA was extracted and EPCR gene product was amplified by a standard PCR reaction.Gene product bands were sequenced to identify EPCR gene polymorphisms.Results In the control group, the level of sEPCR in subjects with 6936AG genotype was significantly higher than that in subjects with 6936AA genotype ((0.97±0.32) pg/ml vs. (0.61±0.24) pg/ml, P <0.01). Similarly in the DVT group, the level of sEPCR in subjects with the 6936AG were greater than that in subjects with the 6936AA genotype ((0.87±0.21) pg/ml vs. (0.50±0.18) pg/ml, P <0.01). The sEPCR level in DVT patients was significantly higher than that in healthy controls ((0.68±0.32) pg/ml vs. (0.54±0.22) pg/ml, P <0.05). The 6936AG genotype frequency in DVT patients was significantly higher than that in healthy controls (P <0.05). In contrast, the 6936AA genotype frequency in DVT patients was lower than that in healthy controls (P <0.05). Subjects carrying 6936AG had an increased risk of thrombosis (OR=2.75, 95% CI:1.04-7.30, P <0.05).Conclusions EPCR gene 6936A/G polymorphism is associated with increased plasma levels of sEPCR. Subjects carrying 6936AG likely have an increased risk of thrombosis.

    A 4-year-old girl was referred for evaluation for a mild but persistent serum aspartate aminotransferase (AST) elevation detected incidentally during routine blood screening for a skin infection. Serum creatine kinase activity was found to be increased. Immuno-histochemical study for dystrophin in her muscle biopsy showed results consistent with a carrier state for muscular dystrophy. Molecular work-up showed the proposita to be a carrier of a deletion mutation of exon 48 of the dystrophin gene. Four male relatives also had the deletion mutation, yet showed no clinical symptoms of muscular dystrophy (age range 8-58 yrs). Linkage analysis of the dystrophin gene in the family showed a spontaneous change of an STR45 allele, which could be due to either an intragenic double recombination event, or CA repeat length mutation leading to identical size alleles. To our knowledge, this is the first documentation of an asymptomatic dystrophinopathy in multiple males of advanced age. Based on molecular findings, this family would be given a diagnosis of Becker muscular dystrophy. This diagnosis implies the development of clinical symptoms, even though this family is clearly asymptomatic. This report underscores the caution which must be exercised when giving presymptomatic diagnoses based on molecular studies. 28 refs., 4 figs., 1 tab.

    Venous thromboembolism is known to be a complex interaction of genetic and acquired factors leading to thrombosis. JAK2V617F mutation is believed to contribute to a thrombophilic phenotype, possibly through enhanced leukocyte-platelet interactions in myeloproliferative neoplasms (MPNs). Several studies have focused on the importance of screening for JAK2V617F mutation in patients with splanchnic venous thrombosis (VT) for the detection of nonovert MPNs. The role of JAK2V617F mutation in VT outside the splanchnic region is still widely unsettled. The primary aim of this study was to find out the prevalence of JAK2V617F mutation in patients with deep venous thrombosis (DVT), its clinical significance as a prothrombotic risk factor, and its possible interactions with other genetic thrombophilic risk factors. A total of 148 patients with idiopathic, symptomatic DVT were evaluated. Median age of presentation was 32 years (range 15-71 years) with a sex ratio of 1.3:1. Overall, the most common genetic prothrombotic factor was factor V Leiden mutation, found in 10.8% (16 of 148) of patients who also showed strong association with increased risk of thrombosis (odds ratio 5.94, confidence interval 1.33-26.4, P = .019). Deficiencies in protein C, protein S, and antithrombin were seen in 8 (5.4%), 10 (6.7%), and 8 (5.4%) patients, respectively. It was observed that the frequency of JAK2V617F mutation was lower in Indian patients, and it also showed weaker association with risk of thrombosis, at least in cases of venous thrombosis outside the splanchnic region.

    Full Text Available Agenesis of the inferior vena cava (IVC is a rare anomaly which can be identified as incidental finding or can be associated with iliofemoral vein thrombosis. IVC agenesis has a known association with renal anomalies which are mainly confined to the right kidney. We describe a case of a 14-year-old male who presented with left leg swelling and pain. Ultrasonography confirmed the presence of left leg deep vein thrombosis (DVT. No underlying hematologic risk factors were identified. A CT scan was obtained which demonstrated absent infrarenal IVC and extensive thrombosis in the left deep venous system and development of collateral venous flow into the azygous/hemiazygous system, with extension of thrombus into paraspinal collaterals. An additional finding in the patient was an atrophic left kidney and stenosis of an accessory left renal artery. Agenesis of the IVC should be considered in a young patient presenting with lower extremity DVT, especially in patients with no risk factors for thrombosis. As agenesis of the IVC cannot be corrected, one should be aware that there is a lifelong risk of lower extremity DVT.

    We present the case of a 17-year-old girl who suddenly woke up with localized pain in the left groin and the inability to twist her leg. After comprehensive physician and laboratory examinations, deep venous thrombosis with consequent pulmonary embolism was ascertained. She had not experienced any recent trauma, but she had started to take oral contraceptives 6 months prior to the onset of the symptoms. Her parents and sisters had been asymptomatic throughout their lives, but the family history revealed a few thromboembolic accidents. Using DNA analysis, heterozygosity for factor V Leiden, prothrombin gene mutation G20210A and methylenetetrahydrofolate reductase C677T, as well as the homozygous 4G/4G genotype in the plasminogen activator inhibitor 1 were identified in our patient. Subsequently, DNA analysis was performed in all living family members, and multiple factors associated with thrombophilia were discovered. Our case confirms the multifactorial cause of thromboembolic events and emphasizes the importance of oral contraceptive use in the onset of venous thrombosis, especially in teenage females. In addition, this case indicates that teenage females with a family history of thrombosis who are making choices about contraception could most likely benefit from advanced thrombophilia testing.

    Venous thromboembolism (VTE) encompasses deep-vein thrombosis (DVT) and pulmonary embolism. VTE is the leading cause of lost disability-adjusted life years and the third leading cause of cardiovascular death in the world. DVT leads to post-thrombotic syndrome, whereas pulmonary embolism can cause chronic pulmonary hypertension, both of which reduce quality of life. Genetic and acquired risk factors for thrombosis include non-O blood groups, factor V Leiden mutation, oral contraceptive use, hormone replacement therapy, advanced age, surgery, hospitalization and long-haul travel. A combination of blood stasis, plasma hypercoagulability and endothelial dysfunction is thought to trigger thrombosis, which starts most often in the valve pockets of large veins. Animal studies have revealed pathogenic roles for leukocytes, platelets, tissue factor-positive microvesicles, neutrophil extracellular traps and factors XI and XII. Diagnosis of VTE requires testing and exclusion of other pathologies, and typically involves laboratory measures (such as D-dimer) and diagnostic imaging. VTE is treated with anticoagulants and occasionally with thrombolytics to prevent thrombus extension and to reduce thrombus size. Anticoagulants are also used to reduce recurrence. New therapies with improved safety profiles are needed to prevent and treat venous thrombosis. For an illustrated summary of this Primer, visit: http://go.nature.com/8ZyCuY. PMID:27189130

    Fourteen patients with deep venous thrombosis (DVT) and a positive sup(99m)Tc-plasmin test were followed up to determine how soon a negative test was obtained. Localization and extension of the thrombi were determined by phlebography. Plasminogen activator activity in vein walls and local fibrinolytic activity after venous occlusion were measured in order to find out what the prerequisites for impaired thrombolysis are. The time required to obtain a negative sup(99m)Tc-plasmin test showed considerable variation, ranging from less than 1 week to more than 6 months. The sup(99m)Tc-plasmin test had returned to normal in 64% of the patients after 6 months. No relationship was found between vessel wall fibrinolysis and time to normalization. Instead, we found an association between the time to normalization of the sup(99m)Tc-plasmin test and the size of the thrombus, according to phlebography, as well as between the time to normalization of the sup(99m)Tc-plasmin test and the extension of leg points with a positive sup(99m)Tc-plasmin test at admission. The finding of abnormal sup(99m)Tc-plasmin test results more than 6 months after acute DVT is of practical importance and warrants caution when evaluating patients with symptoms and signs suggestive of acute recurrent DVT.

    Lower extremity deep venous thrombosis (DVT) is uncommon in the pediatric population, but it can be associated with severe symptoms and potential long-term morbidity secondary to post-thrombotic syndrome. Inferior vena cava (IVC) atresia can predispose a patient to the development of extremity DVT. There is no clear consensus on optimal management of extensive extremity DVT in pediatric patients, especially in patients with IVC anomalies. We report a case of iliofemoral DVT in a 9-year-old boy with IVC atresia and presumed protein S deficiency that was treated successfully using pharmacomechanical thrombectomy and catheter-directed thrombolysis. He was maintained on long-term anticoagulation and remained symptom free at 6 months' follow-up.

    We report on a 42-year-old male who presented with priapism, severe scrotal swelling, and left lower extremity pain and swelling. Initial management of priapism failed, and he was noted to have both cavernosal and glandular venous obstruction. Computed tomography (CT) was performed and identified extensive acute thrombosis involving the distal inferior vena cava and the left iliac veins. Pharmacomechanical thrombolysis (PMT) was started over the course of two days. At completion of thrombolysis, the culprit lesion in the left common iliac vein was treated with angioplasty and stenting. His postoperative course was uneventful, and his priapism as well as the scrotal and leg swelling improved. He was discharged home on full anticoagulation. To our knowledge, this is the first available description of this rare presentation along with a literature review of the underlying vascular etiology for priapism.

    Objectives: To evaluate the feasibility and efficacy of the retrievable Guenther Tulip Vena Cava Filter in the prevention of pulmonary embolism in patients with acute deep vein thrombosis in the perinatal period and to discuss the technical demands associated with the filter's implantation and retrieval. Methods: Between 1996 until 2007, eight women (mean age 27.4 years, range 20-42 years) with acute deep iliofemoral venous thrombosis in the perinatal period of pregnancy and increased risk of pulmonary embolism during delivery were indicated for retrievable Guenther Tulip Vena Cava Filter implantation. All filters were inserted and removed under local anesthesia from the jugular approach. Results: The Guenther Tulip Vena Cava Filter was implanted suprarenally in all patients on the day of caesarean delivery. In follow-up cavograms performed just before planned filter removal, no embolus was seen in the filter in any patient. In all patients the filter was retrieved without complications on the 12th day after implantation. Conclusions: Retrievable Guenther Tulip Vena Cava Filters can be inserted and removed in patients during the perinatal period without major complications.

    Endothelial cell protein C receptor (EPCR) enhances the generation of activated protein C by the thrombin-thrombomodulin complex. A soluble form of EPCR (sEPCR) is present in plasma. Two polymorphisms in the EPCR gene (6936A/G and 4678G/C) have been reported to influence the risk of venous thromboembolism. We aimed to investigate the relation between EPCR gene polymorphisms (6936A/G and 4678C/G) and deep venous thrombosis (DVT) and their relations to sEPCR level. This study involved 90 patients with DVT and 90 age and sex-matched healthy controls. Plasma levels of sEPCR were measured in 45 cases of the primary DVT by ELISA. PCR-restriction fragment length polymorphism (RFLP) was used for detection of EPCR polymorphisms (6936A/G and 4678G/C). Regarding 6936A/G, our results demonstrated that mutant genotypes (AG, GG) were associated with an increased risk for DVT [P mutant allele G (P mutant genotypes were associated with increased levels of sEPCR. Although in 4678G/C, our results demonstrated that the mutant genotype (CC) was considered as a protective factor against DVT (P = 0.014, OR 0.289, 95% CI 0.108-0.776) as well as its mutant allele C (P = 0.02, OR 0.600, 95% CI 0.388-0.927), but it had no effect on sEPCR level. Our data suggest that 6936A/G polymorphism is a risk factor for DVT and is associated with elevated plasma levels of sEPCR, while 4678G/C polymorphism plays a role in protection against DVT.

    Residual venous obstruction (RVO) could improve the stratification of the risk of recurrence after unprovoked deep vein thrombosis (DVT), but results from clinical studies and study-level meta-analyses are conflicting. It was the objective of this analysis to determine if RVO is a valid predictor of recurrent venous thromboembolism (VTE) in patients with a first unprovoked DVT who had received at least three months of anticoagulant therapy. Individual patient data were obtained from the datasets of original studies, after a systematic search of electronic databases (Medline, Embase, Cochrane Library), supplemented by manual reviewing of the reference lists and contacting content experts. A multivariate, shared-frailty Cox model was used to calculate hazard ratios (HRs) for recurrent VTE, including, as covariates: RVO; age; sex; anticoagulation duration before RVO assessment; and anticoagulation continuation after RVO assessment. A total of 2,527 patients from 10 prospective studies were included. RVO was found in 1,380 patients (55.1%) after a median of six months from a first unprovoked DVT. Recurrent VTE occurred in 399 patients (15.8%) during a median follow-up of 23.3 months. After multivariate Cox analysis, RVO was independently associated with recurrent VTE (HR = 1.32, 95% confidence interval [CI]: 1.06-1.65). The association was stronger if RVO was detected early, i.e. at three months after DVT (HR = 2.17; 95% CI: 1.11-4.25), but non-significant if detected later, i.e. >6 months (HR = 1.19; 95% CI: 0.87-1.61). In conclusion, after a first unprovoked DVT, RVO is a weak overall predictor of recurrent VTE. The association is stronger if RVO is detected at an earlier time (3 months) after thrombosis.

    Objectives: The purpose of this study was to evaluate the necessity of and recommend indications for inferior vena cava (IVC) filter implantation during percutaneous endovenous intervention (PEVI) for deep venous thrombosis (DVT).BackgroundPEVI has emerged as a powerful tool in the management of acute proximal DVT. Instrumentation of extensive fresh thrombus is potentially associated with iatrogenic pulmonary embolism (PE). The true frequency of this complication has not been studied in a randomized fashion. We evaluated IVC filter implantation during PEVI for DVT. Methods: A total of 141 patients with symptomatic proximal DVT undergoing PEVI for symptomatic DVT were randomized to receive an IVC filter (70 patients) or no filter (71 patients; control group). The anticoagulation and PEVI regimen were similar between the two groups. Patients with development of symptoms suggestive of PE underwent objective testing for PE. Results: PE developed in 1 of the 14 symptomatic patients in the filter group and 8 of the 22 patients in the control group (P = 0.048). There was no mortality in any group. Three patients (4.2%) in the control group had transient hemodynamic instability necessitating resuscitory efforts. Predictors of iatrogenic PE were found to be PE at admission; involvement of two or more adjacent venous segments with acute thrombus; inflammatory form of DVT (severe erythema, edema, pain, and induration); and vein diameter of {>=}7 mm with preserved architecture. Conclusions: IVC filter implantation during PEVI reduces the risk of iatrogenic PE by eightfold without a mortality benefit. A selective approach may be exercised in filter implantation during PEVI.

    Antiphospholipid antibodies (AA) are immunoglobulins that cross-react with phospholipid on cell membrane, and are therefore associated with a hypercoagulable state manifested by arterial/venous thromboses. We aimed to determine the prevalence of deep venous thrombosis in the lower limbs and the pelvic region (DVT) and pulmonary embolism (PE) in patients with positive AA. Sixty-six patients (48 female, 18 male) with positive lupus anticoagulant (LA) and/or positive anticardiolipin antibody (aCL) underwent radionuclide (RN) venography with 370 MBq of {sup 99m}Tc-MAA. Pulmonary perfusion scintigraphy was performed in 58 patients. Fifteen patients had positive LA and positive aCL (LA+/aCL+), 33 patients had positive LA only (LA+/aCL-) and 18 patients had positive aCL only (LA-/aCL+). Forty-three patients were diagnosed with primary antiphospholipid syndrome (APS) and 19 were diagnosed with APS associated with SLE. DVT was detected in 21 of 66 patients (32%). Patients with LA+/aCL+ showed higher prevalence of DVT (53%) as compared to LA+/aCL- (27%) and LA-/aCL+ (22%). PE was found in 13 of 58 patients (22%). The prevalence of PE was higher in patients with positive aCL (33% in LA+/aCL+; 36% in LA-/aCL+) than in patients with negative aCL (10%). Because of the high prevalence of DVT and PE in patients with AA, RN scintigraphy must be recommended in screening for these clinical troubles. These results indicate that the prevalence of DVT and PE may vary in subgroups of AA. (author)

    Agreement rate between magnetic resonance imaging (MRI) and Doppler ultrasound (DUS) for the detection of deep vein thrombosis (DVT) in the lower extremities was attempted by using the intravascular MRI contrast agent gadofosveset trisodium. The potential of this method to detect pulmonary embolism (PE) was also evaluated. Forty-three consecutive inpatients with ultrasound-confirmed DVT but no clinical signs of PE were prospectively enrolled in this feasibility study. MRI was performed after a single injection of gadofosveset trisodium. The pulmonary arteries were imaged using a 3D Fast Low Angle Shot (FLASH) gradient recalled echo sequence. Additionally, pulmonary arteries, abdominal veins, pelvic and leg veins were imaged using a fat-suppressed 3D gradient echo Volume Interpolated Breath-hold Examination (VIBE FS). Gadofosveset trisodium-enhanced MRI detected more thrombi in the pelvic region, upper leg and lower leg than the initial DUS. In addition, PE was detected in 16 of the 43 DVT patients (37%). This study shows the feasibility of a combined protocol for the MRI diagnosis of DVT and PE using gadofosveset trisodium. This procedure is not only more sensitive in detecting DVT compared to standard DUS, but is also able to detect PE in asymptomatic patients. (orig.)

    Venous duplex ultrasound and plethysmography are used to evaluate patients for suspected deep venous thrombosis (DVT) or venous insufficiency symptoms. Testing can provide clinicians with detailed information on location, extent, and severity of venous conditions before and after treatment. Duplex ultrasound can image the venous system from the vena cava to the peripheral veins, including veins of the calf musculature, and is the recommended technique to diagnose DVT. Accurate interpretation of venous testing requires an understanding of venous hemodynamics, including normal flow phasicity with cardiac and respiratory motion and the changes produced by acute DVT. Duplex scanning provides a roadmap of vein anatomy similar to contrast venography and essential hemodynamic information about the presence of proximal obstruction, vein valve function, and perforator vein reflux. Indications for testing include the diagnosis of acute/chronic DVT and evaluation of patients with venous insufficiency manifested as edema, varicose veins, or ambulatory venous hypertension. Venous plethysmography, an indirect physiologic test, can be used to estimate severity of obstructive or reflux venous pathophysiology and document improvement in venous hemodynamics after intervention. Using criteria based on ultrasound imaging and physiologic testing, venous conditions producing a swollen or painful limb can be accurately determined and aid in appropriate treatment selection.

Methods WBC, PLT count and HB in two groups patients' peripheral blood, and coagulative funtion of pre-operation, and rate of deep venous thrombosis of two groups were analyzed. Results WBC count in hepatocirrhosis group recovered to normal in short time after operation; no difference of HB between two groups; PLT count of two groups were higher than that of the normal patients, but that in the trauma group was higher than that in the hepatocirrhosis groups; no difference of coagulative funtion pre-operation between two groups; the rate of deep venous thrombosis in the hepatocirrhosis group was higher than that in the trauma. Conclusion There is some relation between deep venous thrombosis and higher PLT count,but not the major cause. Using contrast enhanced CT and color Doppler flow imaging (CDFI) after splenectomy is necessary. Once diagnosis of deep venous thrombosis is confm-ned, adequate anticoagulant therapy should be given.

    Full Text Available Venous thrombosis, including deep vein thrombosis and pulmonary embolism, is a common disease that frequently recurs. Recurrence can be prevented by anticoagulants, but this comes at the risk of bleeding. Therefore, assessment of the risk of recurrence is important to balance the risks and benefits of anticoagulant treatment. This review briefly outlines what is currently known about the epidemiology of recurrent venous thrombosis, and focuses in more detail on potential new risk factors for venous recurrence. The general implications of these findings in patient management are discussed.

    Forty-eight patients (25 M, 23 F) age range 25 to 83 years were admitted for treatment of deep vein thrombosis (DVT) of lower limbs confirmed by phlebocavography. Lesions were sural in 6 cases (Gr. 1), subcrural in 28 (Gr. 2) and supracrural in 13 (Gr. 3). Rheoplethysmography with venous occlusion (ORP) was performed and repeated every four months until (possible) recovery of normal emptying parameters (EI). Mean observation period was 25 +/- 8 months. In group 1, ORP indices were always restored to normal values within 4 months. In groups 2 and 3, normal values of IDV were observed in 23/38 patients within a median period of 10 months. Actuarial analysis of changes in EI values showed normalization in 65% of patients within 12 to 16 months with lack of significant differences between values for groups 2 and 3. Beyond this period of time any recovery of normal emptying indices is more aleatory, the residual obstructive syndrome appearing to be established definitely. Antivitamin K therapy (AVK) was instituted in 44 patients, and discontinuation was a function of normalization of EI. Good long-term results (clinical and ORP) were noted in 26/28 cases: one patient had recurrence of DVT with regional extension of thrombus and another a thrombosis on a Mobin-Uddin filter. Restoration of normal EI values during the 16 months following onset of DVT of lower limbs constitutes a valuable index for cessation of AVK therapy. After this period, recovery from the obstructive syndrome is more aleatory and decision to continue therapy must be based on other criteria.

    Full Text Available Venous thromboembolism (VTE has been a subject of great interest of late. Since Rudolph Virchow described the famous Virchow′s triad in 1856, there have been rapid strides in the understanding of the pathogenesis and factors responsible for it. Discovery of various thrombophilic factors, both primary and acquired, in the last 40 years has revolutionized prognostication and management of this potentially life-threatening condition due to its associated complication of pulmonary thromboembolism. Detailed genetic mapping and linkage analyses have been underlining the fact that VTE is a multifactorial disorder and a complex one. There are many gene-gene and gene-environment interactions that alter and magnify the clinical picture in this disorder. Point in case is pregnancy, where the risk of VTE is 100-150 times increased in the presence of Factor V Leiden, prothrombin mutation (Prothrombin 20210A and antithrombin deficiency. Risk of VTE associated with long-haul air flight has now been well recognized. Thrombotic events associated with antiphospholipid syndrome (APS are 70% venous and 30% arterial. Deep venous thrombosis and pulmonary embolism are the most common venous events, though unusual cases of catastrophes due to central vein thrombosis like renal vein thrombosis and Budd-Chiari syndrome (catastrophic APS may occur.

    Full Text Available Background: After discontinuing oral anticoagulant therapy (OAT, the recurrence of venous thromboembolism (VTE is greatest in the 1 st year and gradually diminishes. D-dimer assay was proposed to be effective in selecting patients with idiopathic DVT. The aim of this study was to determine the rate of VTE recurrence after discontinuing OAT according to the results of D-dimer. Materials and Methods: This prospective study was conducted in patients with a first episode of symptomatic proximal deep vein thrombosis (DVT who had received OAT for at least 3 months. Patients were re-evaluated at 1 st , 6 th and 12 th months of their follow-up. At the first (T0 and 30-day (T1 visits, venous blood samples were taken for D-dimer test. At each follow-up visit, we examined patients for clinical symptoms or signs of recurrent VTE, bleeding, postthrombotic manifestations, adherence to treatment, and concomitant analgesic or antiinflammatory therapy. The endpoint outcomes were VTE recurrence and complete of this survey follow-ups. Results: A total of 68 eligible patients was enrolled. Four patients (two patients need to use long-term oral anticoagulation, and two patients lost their first follow-up were excluded. At T0, D-dimer and compression ultrasonongraphy (CUS was normal in 28 patients (44%. Moreover, 36 patients had abnormal D-dimer but normal CUS. A follow-up of 12 months was available in 44 patients. During the follow-up, three recurrent events were recorded. All Recurrent events were ipsilateral DVT. Among these index cases, all had an abnormal D-dimer at either T0 and/or T1. The recurrence rate was higher in males than in females (8.6% vs. 2.2%, P = 0.04 with an abnormal D-dimer at T0 and/or T1 with a multivariate hazard ratio of 2.1 (95% confidence intervals [CI]: 1.2-5.2; P = 0.02. Patients older than 65 years had a higher rate of events than younger and hazard ratio was about 3.8 (95% CI: 2.1-4.2; P = 0.02. Patients with recurrences had higher

OBJECTIVES: To verify whether pharmacological prophylaxis of deep venous thrombosis is being adequately and routinely used in our service and to evaluate physicians' knowledge about the indications of deep venous thrombosis chemoprophylaxis. METHODS: A prospective study was accomplished including 850 patients hospitalized from March to May 2007 at Hospital Geral de Roraima. Clinical, pharmacological and surgical factors were researched. Risk stratification and evaluation of prophylaxis were established according to the classification suggested by the Brazilian Society of Angiology and Vascular Surgery and to the protocol developed by Caiafa in 2002. Physicians answered a questionnaire and analyzed three hypothetical clinical cases. Data were tabled and statistically analyzed with the support of the software Epi-Info 2002®. RESULTS: Of the 850 patients surveyed, 557 (66.66% were clinical and 293 (33.34% were surgical patients. Of the total, 353 (41.56% had low risk, 411 (48.32% medium risk and 86 (10.12% high risk for development of deep venous thrombosis. Of the 497 patients that needed to receive chemoprophylaxis for deep venous thrombosis, only 120 (24% received it and of these, 102 (85% received it adequately. Any patient who did not need prophylaxis received it. Clinical physicians prescribed prophylaxis more frequently and correctly than surgeons, although the latter have demonstrated better theoretical knowledge of the theme. In general, theoretical knowledge on deep venous thrombosis was insufficient. CONCLUSIONS: In our hospital, chemoprophylaxis for deep venous thrombosis is underused in patients indicated for receiving it

  17. Asymptomatic uterine fibroids.

    Divakar, Hema

    2008-08-01

    It is estimated that at least 50% of fibroids are asymptomatic, but this figure is likely to be an underestimate as it is based on women in whom fibroids are found incidentally during another procedure (e.g. cervical screening), and there is little, if any, data from population studies on the true incidence of fibroids. If a prevalence of 50% by 50 years of age is accepted, a large number of women have asymptomatic fibroids. Working on the cliché, 'if it ain't broken, don't fix it', it may seem surprising that there should be a chapter dedicated to the issue of asymptomatic fibroids, since the simplistic approach might be to leave the asymptomatic fibroids well alone. However, asymptomatic fibroids may become symptomatic in the future, so it may be wiser to treat fibroids before they grow to a size when they become symptomatic, or treatment becomes more challenging, especially in young women who may desire fertility at a later stage, and in view of the fact that many women are starting their families in their mid-thirties when they have a 30% chance of having a fibroid(s). Despite their common occurrence, fibroids are still poorly understood. It is not known why they form in the first place, what determines their number and ultimate size, the best treatment approaches, or the factors that determine which women develop symptoms. Even when women present with disorders such as infertility, pelvic pain and abnormal bleeding, it is not always possible to be certain that a given myoma is not simply an innocent bystander rather than the cause of the symptom. This chapter addresses the challenging issue of what to do when fibroids are diagnosed incidentally. Firstly, there is the need to ascertain that the pelvic mass palpated is indeed a fibroid, and not an early, more sinister tumour, especially if conservative management is adopted. In addition, there is the issue of size, position and potential for becoming symptomatic at a later date. With the availability of uterine

    Objective: To evaluate the occurrence and the correlation between pulmonary embolism (PE) and deep venous thrombosis (DVT) using a single CT angiography protocol. Materials and methods: This was a prospective study performed at Hospital Copa D'Or, Rio de Janeiro, Brazil from July 2003 to June 2004. We analyzed 116 CT angiography examinations of patients with clinical suspicion of PE. After an interval of approximately three minutes, venous phase images from the diaphragm to the knees were acquired without additional contrast injection in order to determine the presence of DVT. Results: From the 116 patients studied, 23 (19.8%) had PE, 24 (20.7%) had DVT, 15 (12.9%) had both PE and DVT and 9 (7.8%) had DVT alone. Among the 23 cases of PE, 15 (65.2%) had concomitant DVT whereas 8 (34.8%) had only PE. Among the 24 cases of DVT, 15 (62.5%) had associated PE and 9 (37.5%) had DVT alone. Conclusion: The results showed a strong relationship between PE and DVT, as well as the importance of investigating DVT in cases with suspected PE and the benefits of performing indirect CT venography after pulmonary CT angiography as a single examination alternative method for simultaneous investigation of PE and DVT.

    Background: When exogenous testosterone or treatments to elevate testosterone (human chorionic gonadotropin [HCG] or Clomid) are prescribed for men who have antecedent thrombophilia, deep venous thrombosis and pulmonary embolism often occur and may recur despite adequate anticoagulation if testosterone therapy is continued. Case Presentation: A 55-year-old white male was referred to us because of 4 thrombotic events, 3 despite adequate anticoagulation over a 5-year period. We assessed interactions between thrombophilia, exogenous testosterone therapy, and recurrent thrombosis. In 2009, despite low-normal serum testosterone 334 ng/dL (lower normal limit [LNL] 300 ng/dL), he was given testosterone (TT) cypionate (50 mg/week) and human chorionic gonadotropin (HCG; 500 units/week) for presumed hypogonadism. Ten months later, with supranormal serum T (1385 ng/dL, upper normal limit [UNL] 827 ng/dL) and estradiol (E2) 45 pg/mL (UNL 41 pg/mL), he had a pulmonary embolus (PE) and was then anticoagulated for 2 years (enoxaparin, then warfarin). Four years later, on TT-HCG, he had his first deep venous thrombosis (DVT). TT was stopped and HCG continued; he was anticoagulated (enoxaparin, then warfarin, then apixaban, then fondaparinux). One year after his first DVT, on HCG, still on fondaparinux, he had a second DVT (5/315), was anticoagulated (enoxaparin + warfarin), with a Greenfield filter placed, but 8 days later had a second PE. Thrombophilia testing revealed the lupus anticoagulant. After stopping HCG, and maintained on warfarin, he has been free of further DVT-PE for 9 months. Conclusion: When DVT-PE occur on TT or HCG, in the presence of thrombophilia, TT-HCG should be stopped, lest DVT-PE reoccur despite concurrent anticoagulation. PMID:27536705

    Because deep vein thrombosis (DVT) can occur following orthopaedic procedures, knowledge of hereditary and acquired risk factors for DVT is essential. Hereditary forms of thrombophilia include factor V Leiden and prothrombin G20210A mutations, and deficiencies of antithrombin III, protein C, and protein S. Acquired risk factors include but are not limited to trauma, immobilization, and surgical procedures. In general, athletes have a low risk of venous thrombosis; however, this population is exposed to many acquired thrombogenic risk factors, including hemoconcentration, trauma, immobilization, long-distance travel, and the use of oral contraceptives. Thus, orthopaedic surgeons should consider screening athletes for thrombogenic risk factors, including history of venous thrombosis, hypercoagulable disorders, or high altitude exercise, during preparticipation physicals and preoperative examinations. If a patient is determined to be at high risk of DVT, preventive measures such as physical antithrombotic measures and/or low-molecular-weight heparin should be instituted. If an athlete develops a DVT, a risk factor assessment should be conducted along with anticoagulation treatment in accordance with the American College of Chest Physicians guidelines. PMID:23378374

    Full Text Available Sebastian Werth, Kai Halbritter, Jan Beyer-WestendorfCenter for Vascular Medicine and Department of Medicine III, Division of Angiology, University Hospital “Carl Gustav Carus” Dresden, Dresden, GermanyAbstract: Over the last 15 years, low-molecular-weight heparins (LMWHs have been accepted as the “gold standard” for pharmaceutical thromboprophylaxis in patients at high risk of venous thromboembolism (VTE in most countries around the world. Patients undergoing major orthopedic surgery (MOS represent a population with high risk of VTE, which may remain asymptomatic or become symptomatic as deep vein thrombosis or pulmonary embolism. Numerous trials have investigated LMWH thromboprophylaxis in this population and demonstrated high efficacy and safety of these substances. However, LMWHs have a number of disadvantages, which limit the acceptance of patients and physicians, especially in prolonged prophylaxis up to 35 days after MOS. Consequently, new oral anticoagulants (NOACs were developed that are of synthetic origin and act as direct and very specific inhibitors of different factors in the coagulation cascade. The most developed NOACs are dabigatran, rivaroxaban, and apixaban, all of which are approved for thromboprophylaxis in MOS in a number of countries around the world. This review is focused on the pharmacological characteristics of apixaban in comparison with other NOACs, on the impact of NOAC on VTE prophylaxis in daily care, and on the management of specific situations such as bleeding complications during NOAC therapy.Keywords: major orthopedic surgery, apixaban, dabigatran, edoxaban, rivaroxaban, deep vein thrombosis, venous thromboembolism, VTE prophylaxis

    Thrombosis occurs at sites of injury to the vessel wall, by inflammatory processes leading to activation of platelets, platelet adherence to the vessel wall and the formation of a fibrin network. A thrombus that goes on to occlude a blood vessel is known as a thromboembolism. Venous thromboembolism begins with deep vein thrombosis (DVT), which forms in the deep veins of the leg (calf) or pelvis. In some cases, the DVT becomes detached from the vein and is transported to the right-hand side of the heart, and from there to the pulmonary arteries, giving rise to a pulmonary embolism (PE). Certain factors predispose patients toward the development of venous thromboembolism (VTE), including surgery, trauma, hospitalization, immobilization, cancer, long-haul travel, increased age, obesity, major medical illness and previous VTE; in addition, there may also be a genetic component to VTE. VTE is responsible for a substantial number of deaths per annum in Europe. Anticoagulants are the mainstay of both VTE treatment and VTE prevention, and many professional organizations have published guidelines on the appropriate use of anticoagulant therapies for VTE. Treatment of VTE aims to prevent morbidity and mortality associated with the disease, and any long-term complications such as VTE recurrence or post-thrombotic syndrome. Generally, guidelines recommend the use of low molecular weight heparins (LMWH), unfractionated heparin (UFH) or fondaparinux for the pharmacological prevention and treatment of VTE, with the duration of therapy varying according to the baseline characteristics and risk profile of the individual. Despite evidence showing that the use of anticoagulation prevents VTE, the availability of several convenient, effective anticoagulant therapies and the existence of clear guideline recommendations, thromboprophylaxis is underused, particularly in patients not undergoing surgery. Greater adherence to guideline-recommended therapies, such as LMWH, which can be

    International Nuclear Information System (INIS)

    For the purpose of studying the incidence, pathomorphology and etiology of asymptomatic ischemic cerebral lesions, we carried out a brain MRI study on 65 patients with diabetes mellitus accompanied with hypertension who are thought to belong to a high risk group of ischemic cerebrovascular diseases. Excluding the abnormality of tendon reflex due to diabetic neuropathy, sixty percent of the total patients had some mild neurological signs and symptoms, most of them was discrepancy in tendon reflex. The percentage of the patients in whom MRI disclosed some abnormalities was as high as 70%, they were lacunar stroke, multiple lacunar state, cortical infarct, and patchy high signal lesions visible only in the T2 weighted image. Lacunes or these patchy high signal lesions (considered to be the dilatation of the perivascular space or true lacunes) tended to be found along the border zone or the terminal zone. These results indicate that asymptomatic patients in whom MRI discloses the abnormalities should be considered as candidates for the future onset of multi-infarct. (author)

    Venous thrombophilia is the result of clotting changes namely of a hypercoagulable state together with blood flow and vessel wall changes. There is no need for all these components to be present in order for thrombosis to occur. As the matter of fact, thrombosis may occur even if only one of these conditions is present. In clinical practice a combination of factors is usualy seen. In comparison with arterial thrombophilia, clotting changes and blood flow seen to play a major role in venous thrombosis. Venous thrombophilia may remain asynptomatic or may result in a series of clinical syndromes. The commonest of these are: 1. Superficial vein thrombosis, 2. Deep vein thrombosis of legs, 3. Deep vein thrombosis of arms, 4. Caval veins thrombosis, 5. Portal vein thrombosis, 6. Hepatic veins thrombosis, 7. Renal vein thrombosis, 8. Cerebral sinuses thrombosis, 9. Right heart thrombosis, 10. Miscellaneous (ovarian, adrenal veins thrombosis, etc.). Since the first two are widely and easily recognized, these is no need for an extensive discussion. Deep vein thromboses of upper limbs are not as frequent as those of lower limbs or of superficial phlebitis but they can still be recognized on clinical grounds and non invasive techniques. The remaining 7 syndromes are less common and therefore less frequently suspected and recognized. Of particular interest, among these less common manifestations of venous thrombophilia are hepatic vein and renal vein thrombosis. Hepatic veins thrombosis, sometimes part of inferior vena cava thrombosis is most frequently due to an isolated occlusion of hepatic veins thereby causing a form of venocclusive disease. Occasionally diagnosis may be difficult because of slow onset of symptoms (hepatomegaly, right flank pain, fever, ascites etc.). The same is true for renal vein thrombosis which may also be of difficult diagnosis since it causes proteinuria and flank pain. The proteinuria is often interpreted as due to a nephrotic syndrome which

    Behçet's disease is an autoimmune mediated multisystem vasculitis. It is most prevalent in Middle Eastern and Mediterranean patients and considered rare in Afro-Caribbean populations. The disease phenotype in Afro-Caribbean patients is more severe with systemic involvement, in particular lesions affecting the vascular system known as angio-Behçet's. The archetypal triad of disease in Behçet's includes oral stomatitis, genital ulceration and ocular lesions, however, the variety of symptoms patients experience is recognised by the revised International Criteria for Behçet's disease and is reflected in the clinical scoring criteria. The authors report an unusual case of Behçet's disease in a young Afro-Caribbean patient presenting with spontaneous bilateral renal, cerebral and pulmonary venous thrombosis as first presentation.

    Venous malformations (VMs) are non proliferative lesions that consist of dysplastic venous channels. The aim of imaging is to characterise the lesion and define its anatomic extent. We will describe the plain film, ultrasound (US) (including colour and duplex Doppler), computed tomography (CT), magnetic resonance imaging (MRI), conventional angiographic and direct phlebographic appearances of venous malformations. They will be illustrated at a number of head and neck locations, including orbit, oral cavity, superficial and deep facial space, supraglottic and intramuscular. An understanding of the classification of such vascular anomalies is required to define the correct therapeutic procedure to employ. Image-guided sclerotherapy alone or in combination with surgery is now the first line treatment option in many cases of head and neck venous malformations, so the radiologist is now an integral part of the multidisciplinary management team.

    Full Text Available Ola E Dahl1,21Department of Orthopaedics, Innlandet Hospital Trust, Elverum Central Hospital, Elverum, Norway; 2Thrombosis Research Institute, London, UKAbstract: Venous thromboembolism, presenting as deep vein thrombosis or pulmonary embolism, is a major challenge for health care systems. It is the third most common vascular disease after coronary heart disease and stroke, and many hospitalized patients have at least one risk factor. In particular, patients undergoing hip or knee replacement are at risk, with an incidence of asymptomatic deep vein thrombosis of 40%–60% without thromboprophylaxis. Venous thromboembolism is associated with significant mortality and morbidity, with patients being at risk of recurrence, post-thrombotic syndrome, and chronic thromboembolic pulmonary hypertension. Arterial thromboembolism is even more frequent, and atrial fibrillation, the most common embolic source (cardiac arrhythmia, is associated with a five-fold increase in the risk of stroke. Strokes due to atrial fibrillation tend to be more severe and disabling and are more often fatal than strokes due to other causes. Currently, recommended management of both venous and arterial thromboembolism involves the use of anticoagulants such as coumarin and heparin derivatives. These agents are effective, although have characteristics that prevent them from providing optimal anticoagulation and convenience. Hence, new improved oral anticoagulants are being investigated. Dabigatran is a reversible, direct thrombin inhibitor, which is administered as dabigatran etexilate, the oral prodrug. Because it is the first new oral anticoagulant that has been licensed in many countries worldwide for thromboprophylaxis following orthopedic surgery and for stroke prevention in patients with atrial fibrillation, this compound will be the main focus of this review. Dabigatran has been investigated for the treatment of established venous thromboembolism and prevention of

  19. The relationship of intracranial venous pressure to hydrocephalus.

    Little is known about intracranial venous pressure in hydrocephalus. Recently, we reported that naturally occurring hydrocephalus in Beagle dogs was associated with an elevation in cortical venous pressure. We proposed that the normal pathway for cerebrospinal fluid (CSF) absorption includes transcapillary or transvenular absorption of CSF from the interstitial space and that the increase in cortical venous pressure is an initial event resulting in decreased absorption and subsequent hydrocephalus. Further analysis, however, suggests that increased cortical venous pressure reflects the effect of the failure of transvillus absorption with increase in CSF pressure on the venous pressure gradient between ventricle and cortex. Normally, the cortical venous pressure is maintained above CSF pressure by the Starling resistor effect of the lateral lacunae. A similar mechanism is absent in the deep venous system, and thus the pressure in the deep veins is similar to that in the dural sinuses. Decreased CSF absorption causes an increase in CSF pressure followed by an increase in cortical venous pressure without a similar increase in periventricular venous pressure. The periventricular CSF to venous (transparenchymal) pressure (TPP) gradient increases. In contrast, cortical vein pressure remains greater than CSF pressure (negative TPP). The elevated periventricular TPP gradient causes ventricular dilatation and decreased periventricular cerebral blood flow (CBF), a condition that persists even if the CSF pressure returns to normal, particularly if tissue elastance is lessened by tissue damage. If deep CBF is to be maintained, periventricular venous pressure must increase. Since the veins are in a continuum, cortical venous pressure will further increase above the CSF pressure.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8194060

    Increased intracranial pressure is common in cerebral venous thrombosis (CVT), but hydrocephalus is rarely reported in these patients. We examined the frequency, pathophysiology and associated clinical manifestations of hydrocephalus in patients with CVT admitted to our hospital between 2000 and 2010 (prospectively since July 2006). Hydrocephalus was defined as a bicaudate index larger than the 95th percentile for age, and/or a radial width of the temporal horn of ≥ 5 mm. We excluded patients in whom hydrocephalus was caused by a disease other than CVT or if it was iatrogenic. 20 out of 99 patients with CVT had hydrocephalus. 6 patients with hydrocephalus were excluded from the analysis. Patients with hydrocephalus more often had focal neurological deficits (86 vs. 49%, p = 0.02) and were more frequently comatose (43 vs. 16%, p = 0.06), as compared to patients without hydrocephalus. Deep cerebral venous thrombosis (64 vs. 9%, p hydrocephalus. Intraventricular hemorrhage was present in 1 patient with hydrocephalus, compared to none among patients without hydrocephalus (7 vs. 0%, p = 0.15). Outcome at follow-up was worse in patients with hydrocephalus (mRS 0-1, 36 vs. 68%, p = 0.02; mortality 29 vs. 9%, p = 0.07). Hydrocephalus occurs more frequently in cerebral venous thrombosis than previously believed, especially in patients with deep cerebral venous thrombosis and edema of the basal ganglia. The presence of hydrocephalus is associated with a worse clinical outcome, but a direct causal relation is unlikely. Routine shunting procedures are not advisable.

  5. Partial anomalous pulmonary venous return in patients with pulmonary hypertension

    International Nuclear Information System (INIS)

    Anomalous pulmonary venous return is an uncommon congenital malformation, and may be partial or total. Partial anomalous pulmonary venous return (PAPVR) is more common than total anomalous pulmonary venous return, and is often associated with other congenital cardiac anomalies. Whilst many patients with PAPVR remain asymptomatic, some may present in later age with symptoms related to left-to-right shunt, right heart failure and pulmonary hypertension. We report two cases of PAPVR detected on Computed Tomography Pulmonary Angiogram (CTPA) for the work up of pulmonary hypertension. The cases demonstrate that, although uncommon, partial anomalous pulmonary venous return can be a contributing factor to pulmonary hypertension and pulmonary veins should be carefully examined when reading a CTPA study.

    Full Text Available Abstract Objective Behcet's is an idiopathic multi-organ syndrome, which may have onset during childhood. Vascular involvement is uncommon, with rarely reported coronary aneurysm formation. We present a case report of a teenager girl who developed recalcitrant life-threatening Behcet's vasculitis, involving both small and large venous and arterial systems including a giant coronary aneurysm. Case report De-identified data were collected retrospectively in case report format. Although our sixteen year old female with Behcet's vasculitis had resolution of many arterial aneurysms, she had persistent venous thrombosis of large vessels, as well as persistent, giant arterial aneurysms requiring intra-arterial coiling of a lumbar artery and coronary bypass grafting despite intensive immunosuppression including glucocorticoids, cyclophosphamide, infliximab, methotrexate, azathioprine and intravenous immunoglobulin. Conclusions Vascular manifestations may be seen in Behcet's syndrome, including asymptomatic coronary aneurysm, which may be refractory to immunosuppression and ultimately require surgical intervention. Increased awareness is essential for prompt diagnosis and management.

    Full Text Available Venous ulcers are the most common ulcers of the lower limb. It has a high morbidity and results in economic strain both at a personal and at a state level. Chronic venous hypertension either due to primary or secondary venous disease with perforator paucity, destruction or incompetence resulting in reflux is the underlying pathology, but inflammatory reactions mediated through leucocytes, platelet adhesion, formation of pericapillary fibrin cuff, growth factors and macromolecules trapped in tissue result in tissue hypoxia, cell death and ulceration. Duplex scan with colour flow is the most useful investigation for venous disease supplying information about patency, reflux, effects of proximal and distal compression, Valsalva maneuver and effects of muscle contraction. Most venous disease can be managed conservatively by leg elevation and compression bandaging. Drugs of proven benefit in venous disease are pentoxifylline and aspirin, but they work best in conjunction with compression therapy. Once ulceration is chronic or the patient does not respond to or cannot maintain conservative regime, surgical intervention treating the underlying venous hypertension and cover for the ulcer is necessary. The different modalities like sclerotherapy, ligation and stripping of superficial varicose veins, endoscopic subfascial perforator ligation, endovenous laser or radiofrequency ablation have similar long-term results, although short-term recovery is best with radiofrequency and foam sclerotherapy. For deep venous reflux, surgical modalities include repair of incompetent venous valves or transplant or transposition of a competent vein segment with normal valves to replace a post-thrombotic destroyed portion of the deep vein.

    Full Text Available AIDS-associated cholangiopathy is a form of biliary tract inflammation with stricture formation seen in AIDS patients who are severely immunosuppressed. It is no longer common in countries in which HAART therapy is widely employed but is still seen in underdeveloped countries. The majority of patients are symptomatic at the time of presentation. Herein, we describe a seventy-four-year-old woman who presented with unilateral leg swelling after a prolonged airplane flight. She was otherwise entirely asymptomatic. Routine laboratory testing was notable for a hypochromic microcytic anemia, slight leukopenia, and mild hypoalbuminemia. Liver enzymes were all elevated. Deep venous thrombosis was confirmed, and a CT scan of the chest disclosed no pulmonary emboli. However, the visualized portion of the abdomen showed dilatation of the common bile and pancreatic ducts. This was confirmed on ultrasonography and MRCP, and no obstructive lesions were noted. An ERCP revealed a dilated common bile duct without filling defects or strictures. A balloon occlusion cholangiogram showed strictures and beading of the intrahepatic ducts. Shortly thereafter, serology for HIV returned positive along with a depressed CD4 cell count, and the patient was diagnosed with AIDS-associated cholangiography.

    The present review provides an update of the biological profile of Pycnogenol in the light of its use in the treatment of chronic venous insufficiency (CVI) and related venous disorders such as deep vein thrombosis (DVT), post-thrombotic syndrome, long haul air-travel-related leg oedema, venous ulcers and acute haemorrhoids. Pycnogenol is a French maritime pine bark extract produced from the outer bark of Pinus pinaster Ait. subsp. atlantica. Its strong antioxidant, anti-inflammatory and vasodilator activities, antithrombotic effects and collagen stabilizing properties make it uniquely able to target the multi facet pathophysiology of CVI and related venous disorders. Clinical studies have shown that it can reduce oedema of the legs in CVI, reduce the incidence of deep venous thrombosis during long haul flights and enhance the healing of venous ulcers and haemorrhoidal episodes by topical application and/or oral administration. This review highlights clinical research findings on the safety, compliance and efficacy of Pycnogenol, including its use in combination products. PMID:23775628

  16. The diagnostic accuracy of magnetic resonance venography in the detection of deep venous thrombosis: a systematic review and meta-analysis

    International Nuclear Information System (INIS)

    Aim: To search the literature for further evidence for the use of magnetic resonance venography (MRV) in the detection of suspected DVT and to re-evaluate the accuracy of MRV in the detection of suspected deep vein thrombosis (DVT). Materials and methods: PubMed, EMBASE, Scopus, Cochrane, and Web of Science were searched. Study quality and the risk of bias were evaluated using the QUADAS 2. A random effects meta-analysis including subgroup and sensitivity analyses were performed. Results: The search resulted in 23 observational studies all from academic centres. Sixteen articles were included in the meta-analysis. The summary estimates for MRV as a diagnostic non-invasive tool revealed a sensitivity of 93% (95% confidence interval [CI]: 89% to 95%) and specificity of 96% (95% CI: 94% to 97%). The heterogeneity of the studies was high. Inconsistency (I2) for sensitivity and specificity was 80.7% and 77.9%, respectively. Conclusion: Further studies investigating the use of MRV in the detection of suspected DVT did not offer further evidence to support the replacement of ultrasound with MRV as the first-line investigation. However, MRV may offer an alternative tool in the detection/diagnosis of DVT for whom ultrasound is inadequate or not feasible (such as in the obese patient). -- Highlights: •We aimed to search the literature for evidence for the use of MRV in the detection of suspected DVT. •We questioned the use of MRV in special populations like the obese where contrast venography may not be feasible or safe. •MRV may not replace ultrasound as the first-line modality for DVT detection. •Consider MRV use in special populations like the obese where other diagnostic tools are not feasible. •Studies to compare MRV vs. ultrasound as a screening tool for DVT in the obese should be considered

    2002-03-01

    Purpose: To establish a differentiated protocol for multi-slice CT (MSCT) examinations in cases of clinically suspected pulmonary embolism (PE) using pulmonary CT-angiography (CTA) and indirect CT-phlebography (CTP). Materials and Methods: 161 patients with suspected PE were examined using an MSCT (SOMATOM Volume Zoom; Siemens, Forchheim, Germany). After intravenous administration of 120 ml of contrast material, a thin collimation chest-CT scan was performed (120 kV, 100 mAs, collimation: 4 x 1 mm). If PE was present, or previous examinations and clinical signs suggested deep venous thrombosis (DVT), a CTP was subsequently completed. CTPs were performed using a 4 x 5 mm protocol (120 kV, 170 mAs). Venous phase scanning, starting from the pelvic crest, was completed in the popliteal fossa three minutes after contrast material injection. In 73 extremities, CTP were compared to the results of ultrasound, phlebography and autopsy. Scan ranges were documented in all patients. Cumulative doses were calculated for male and female subgroups. Results: 62 patients in our series suffered from PE and in 47 of these patients deep venous thrombosis was seen additionally. Of the 99 patients without PE, 47 also received indirect CTP. CTP confirmed the suspicion and extent of DVT in 8 patients. Only in 2 of 39 patients (5.1%) was previously unknown DVT found, despite the exclusion of PE. Regarding DVT, sensitivity was 94.3% and specificity was 92.1% for indirect CTP. Cumulative chest CT doses averaged 3.3 mSv for males and 4.2 mSv for females, the calculated CTP dosage was 9.3 mSv (according to ICRP 60). Conclusions: the examination protocol presented its suitable for clinical usage in patients with suspected PE. If PE is confirmed, indirect CTP is justified, so that detailed information of the venous system can be obtained. However, the relatively high radiation dosage of an additional CTP requires a strict indication regiment in patients with a negative CTA. (orig.) [German

    Deep vein thrombosis and common complications, including pulmonary embolism and post-thrombotic syndrome, represent a major source of morbidity and mortality worldwide. Experimental models of venous thrombosis have provided considerable insight into the cellular and molecular mechanisms that regulate thrombus formation and subsequent resolution. Here, we critically appraise the ex vivo and in vivo techniques used to assess venous thrombosis in these models. Particular attention is paid to imaging modalities, including magnetic resonance imaging, micro-computed tomography, and high-frequency ultrasound that facilitate longitudinal assessment of thrombus size and composition.

    profunda e tromboembolismo pulmonar.OBJECTIVE: To compare the effectiveness and safety of rivaroxaban to those of enoxaparin for the prophylaxis of deep venous thrombosis (DVT after total hip arthroplasty. METHODS: From September 2006 to April 2007, at the Orthopedics and Traumatology Clinic of the Hospital Complex of the Santa Casa of Porto Alegre, State of Rio Grande do Sul, a randomized, double-blind clinical trial was carried out in which 67 patients were selected (n = 67, all of them submitted to total hip arthroplasty (ATQ. Of these patients, two were excluded for lack of adherence to the prophylaxis proposed after hospital release (n = 65. One of the groups was given subcutaneous 40 mg enoxaparin 6 hours to 8 hours before surgery, and after surgery a placebo pill was added, for once a day oral intake, during the first 32 to 36 days. The other group was given oral 10 mg rivaroxaban, once a day, during the first 32 to 36 post-operative days. In order to have the double-blind feature of the study, a subcutaneous placebo injection was given 6 hours to 8 hours before surgery and on the 32 to 36 days following surgery. The main outcome aimed at was the effectiveness in preventing DVT, which was evaluated by bilateral venography carried out between days 32 and 36 after surgery, or through documented symptoms of deep venous thrombosis or pulmonary thromboembolism (PTE. The secondary outcome studied was administration safety, that was evaluated through major bleeding or liver toxicity. RESULTS: Rivaroxaban and enoxaparin showed similar results (the differences were not statistically significant when compared for the reduction of DVT incidence till the 36th post-operative day. There was no difference in blood loss and liver toxicity when the drugs were compared. CONCLUSION: In patients submitted to total hip arthroplasty, rivaroxaban showed as effective and safe as enoxaparin to prevent deep venous thrombosis and pulmonary thromboembolism.

Ultrasonography may fail to achieve noninvasive diagnosis of these obstructions. The possibility of using Computed Tomography Venography (CTV for these diagnoses is under investigation.Methods:Patients with CVI graded at CEAP clinical classes 3 to 6 and previous treatment failure underwent evaluation with CTV. Percentage obstruction was rated by two independent examiners. Obstruction prevalence and its associations with risk factors and CEAP classification were analyzed.Results:A total of 112 limbs were prospectively evaluated. Mean patient age was 55.8 years and 75.4% were women. Obstructions involved the left lower limb in 71.8% of cases and 35.8% of patients reported a medical history of deep venous thrombosis. Overall, 57.1% of imaging studies demonstrated venous obstruction of at least 50% and 10.7% showed obstruction of >80%. The only risk factor that was found to be independently associated with a significantly higher incidence of >50% venous obstruction was a medical history of DVT (p=0.035 (Fisher's exact test. There was a positive relationship between clinical classification (CEAP and degree of venous obstruction in the limbs studied (Chi-square test for linear trend; p=0.011.Conclusion:Patients with advanced CVI are often affected by obstructions in the iliocaval venous territory and CTV is able to diagnose the degree of obstruction. There is a positive association between degree of obstruction and both previous history of DVT and severity of symptoms of CVI.

    2013-09-01

    Full Text Available Venous thromboembolism (VTE is a major complication of cancer and represents an important cause of morbidity and mortality. The incidence of VTE is 0.6-7.8% in patients with cancer more than double the incidence of VTE in patients without cancer. The risk of VTE which includes deep venous thrombosis (DVT and pulmonary embolism (PE is increased two to seven fold in patients with cancer. VTE risk is especially high among certain groups such as hospitalized patients with cancer and those receiving active antineoplastic therapy. Also cancer patients, who undergoing major surgery, are increased risk of VTE. Trauma, long-haul travel, increased age, obesity, previous VTE and genetic component are also predisposing factors for VTE. Patients with cancer who develop VTE should be managed multidisciplinary treatment guidelines. The primary goal of thromboprophylaxis in patients with cancer is to prevent VTE. The large majority of cancer patients should be treated with therapeutic doses of unfractioned heparin (UFH or low molecular weight heparin (LMWH. Prophylaxis should include cancer patients who underwent major surgery for cancer and patients with a history of VTE.

    Occlusive clot formation in the veins causes venous thrombosis, the site most common in the deep veins of leg, called deep vein thrombosis. The clot can block blood flow and when it breaks off, called an embolism which in turn can damage the vital organs. Venous thrombosis occurs via three mechanisms ie, Virchow's triad. The mechanisms are decreased flow rate of blood, damage to the blood vessel wall and an increased tendency of the blood to clot. There are several factors which can increase a person's risk for deep vein thrombosis. The symptoms of deep vein thrombosis in the legs are pain, swelling and redness of the part. One variety of venous thrombosis is phlegmasia alba dolens where the leg becomes pale and cool. Investigations include Doppler ultrasound examination of the limb, D-dimer blood test, plethysmography of the legs, x-rays to show vein in the affected area (venography). Hospitalisation is necessary in some cases with some risk factors. The mainstream of treatment is with anticoagulants, mostly low molecular weight heparin for 6 months. Deep venous thrombosis is a rising problem. Early diagnosis and treatment is associated with a good prognosis.

    Twentyeight patients with ileofemoral venous thrombosis were treated surgically. Five of the patients had moderate degree of venous congestion, 18 patients had phlegmasia alba dolens and five patients had phlegmasia coerulea dolens. The mean age was 54 years, range 15-80 years, and 15 were men and 13 were women. In all cases the thrombosis was verified by phlebography. Thrombectomy was performed with a Fogarty venous thrombectomy catheter. Peroperative phlebography was used in most cases to guarantee complete extraction of thrombotic material. No operative pulmonary embolism or mortality was encountered. Postoperative continuous heparin infusion in the thrombectomized segment was used for the first week followed by dicumarol treatment. The patients were followed from 6 months to 4 years postoperatively. In two patients thrombectomy was not possible to perform. One of these patients developed a pronounced postthrombotic syndrome, the other developed venous congestion of more moderate degree. Excellent long-term time results were obtained in 82% of the patients and satisfactory in 14%. Thrombectomy is an efficient treatment of ileofemoral venous thrombosis.

    Full Text Available The most frequent ultimate cause of death is myocardial arrest. In many cases this is due to myocardial hypoxia, generally arising from failure of the coronary macro- and microcirculation to deliver enough oxygenated red cells to the cardiomyocytes. The principle reason for this is occlusive thrombosis, either by isolated circulating thrombi, or by rupture of upstream plaque. However, an additionally serious pathology causing potentially fatal stress to the heart is extra-cardiac disease, such as pulmonary hypertension. A primary cause of the latter is pulmonary embolus, considered to be a venous thromboembolism. Whilst the thrombotic scenario has for decades been the dominating paradigm in cardiovascular disease, these issues have, until recently, been infrequently considered in cancer. However, there is now a developing view that cancer is also a thrombotic disease, and notably a disease predominantly of the venous circulation, manifesting as deep vein thrombosis and pulmonary embolism. Indeed, for many, a venous thromboembolism is one of the first symptoms of a developing cancer. Furthermore, many of the standard chemotherapies in cancer are prothrombotic. Accordingly, thromboprophylaxis in cancer with heparins or oral anticoagulation (such as Warfarin, especially in high risk groups (such as those who are immobile and on high dose chemotherapy, may be an important therapy. The objective of this communication is to summarise current views on the epidemiology and pathophysiology of arterial and venous thrombosis in cancer.

    Chronic venous disease, reviewed herein, is manifested by a spectrum of signs and symptoms, including cosmetic spider veins, asymptomatic varicosities, large painful varicose veins, edema, hyperpigmentation and lipodermatosclerosis of skin, and ulceration. However, there is no definitive stepwise progression from spider veins to ulcers and, in fact, severe skin complications of varicose veins, even when extensive, are not guaranteed. Treatment options range from conservative (eg, medications, compression stockings, lifestyle changes) to minimally invasive (eg, sclerotherapy or endoluminal ablation), invasive (surgical techniques), and hybrid (combination of ≥1 therapies). Ms L, a 68-year-old woman with varicose veins, is presented. She has had vein problems over the course of her life. Her varicose veins recurred after initial treatment, and she is now seeking guidance regarding her current treatment options.

Methods A retrospective study was conducted on the clinical data of 10 cases of nephrotic syndrome complicated with DVT and (or) PE, which was compared with 50 synchronous cases of nephrotic syndrome with no thrombosis as to age (AGE) , plasma albumin ( ALB ), 24 - hour urine protein ( 24 - UP), total cholesterol ( CHOL), triglyceride ( TG), platelet (PLT) and fibrinogen (FIB). Results In the thrombosis group, 6 patients underwent renal biopsy , 3 of whom had membranous nephropathy. There were significant differences in the indicators such as AGE , ALB, 24 - UP, FIB between the thrombosis group and the non -thrombosis group (P< 0.05 ); the differences in CHOL, TG and PLT had no statistical significance (P>0.05 ). The thrombi disappeared in the thrombosis group following a series of therapies including anticoagulation , thrombolysis, implantation of inferior vena cava filter (IVCF) , etc. Conclusion AGE, ALB, 24 - UP and FIB play very important roles in the formation off DVT and (or) PE in NS. Membranous nephropathy is the most common pathological type in NS with thromboembolism. In cases of NS complicated with DVT and (or) PE, anticoagulation, thrombolysis or interventional therapy should be conducted as required. Implantation of IVCF is an effective method to prevent DVT leading to PE .%目的 探讨肾病综合征(nephrotic syndrome,NS)并发深静脉血栓形成 (DVT)和(或)肺栓塞(PE)的相关危险因素及诊治体会.方法 对10例确诊的NS并发DVT和(或)PE患者(血栓组)的临床资料进行回顾性分析,并与同期50例NS无血栓患者(无血栓组)的年龄(AGE)、血浆白蛋白(ALB)、24小时尿蛋白定量(24-UP)、总胆固醇(CHOL)、三酰甘油(TG)、血小板(PLT)、纤维蛋白原(FIB)等指标进行比较.结果 血栓组10例,肾活检6

    Full Text Available Context Morbid obesity is associated with various co-morbidities, including chronic venous insufficiency. Bariatric surgery is the only effective treatment for morbid obesity, but with potential risks and possible complications, including venous thromboembolism. Objective To determine the prevalence of clinical and ultrasonographic signs of chronic venous insufficiency in morbid obese patients in preparation for bariatric surgery and the incidence of post-operative venous thromboembolic disease. Methods Patients on work-up for bariatric surgery of Centro Terapêutico Especializado em Fígado (CETEFI and Pro-Gastro surgical teams of the Hospital Beneficência Portuguesa de São Paulo were included. The analysed data were pre-operative findings for venous insufficiency (CEAP - clinical, etiological, anatomical, physiopathologic - classification and venous ultrassonographic findings, type of surgery (open or laparoscopic, abdominal circumference, body mass index (BMI and post-operative ultrassonography search for venous insufficiency and deep venous thrombosis. Results Between March 2007 and December 2009, 95 patients candidates for bariatric surgery had clinical and duplex scan evaluation of the lower limbs venous system. Of the 95 patients, 53 were submitted to the surgical procedure. There was a predominance of women (77.9%, the average age was 38.5 years, average preoperative weight 124.6 kg and average BMI of 45.5 kg/m2. Regarding obesity, 16.8% were obese, and 83.1% were morbidly obese. In relation to the venous findings, 86.3% of the patients did fit CEAP classification less than 3 and 13.7% greater than or equal to 3. Among the post-operative complications, there were four cases of wound infection.

    Venous valves play a crucial role in blood circulation, promoting the one-way movement of blood from superficial and deep veins towards the heart. By preventing retrograde flow, venous valves spare capillaries and venules from being subjected to damaging elevations in pressure, especially during skeletal muscle contraction. Pathologically, valvular incompetence or absence of valves are common features of venous disorders such as chronic venous insufficiency and varicose veins. The underlying causes of these conditions are not well understood, but congenital venous valve aplasia or agenesis may play a role in some cases. Despite progress in the study of cardiac and lymphatic valve morphogenesis, the molecular mechanisms controlling the development and maintenance of venous valves remain poorly understood. Here, we show that in valved veins of the mouse, three gap junction proteins (Connexins, Cxs), Cx37, Cx43, and Cx47, are expressed exclusively in the valves in a highly polarized fashion, with Cx43 on the upstream side of the valve leaflet and Cx37 on the downstream side. Surprisingly, Cx43 expression is strongly induced in the non-valve venous endothelium in superficial veins following wounding of the overlying skin. Moreover, we show that in Cx37-deficient mice, venous valves are entirely absent. Thus, Cx37, a protein involved in cell-cell communication, is one of only a few proteins identified so far as critical for the development or maintenance of venous valves. Because Cxs are necessary for the development of valves in lymphatic vessels as well, our results support the notion of common molecular pathways controlling valve development in veins and lymphatic vessels.

    A study into the normal anatomy of the venous circulation of the gastroesophageal junction was undertaken using three complementary techniques (radiology, corrosion casting, and morphometry). Four distinct zones of venous drainage were defined as follows: (a) gastric zone, characterized by a longitudinal venous distribution; (b) palisade zone, composed of parallel vessels arranged in groups, lying mainly within the lamina propria; (c) perforating zone, characterized by "treble clef" shaped veins, which collect and channel blood into extrinsic veins; and (d) truncal zone, composed of four or five deep lying descending veins. This venous system appeared to be mainly distributed within the esophageal mucosal folds. The anatomic pattern suggests that venous flow is bidirectional at the palisade zone, which acts as a high-resistance watershed region between the portal and azygos systems. In patients with portal hypertension this normal vascular system has to accommodate greatly increased venous flow, and the anatomy as demonstrated here offers insight into variceal development.

    The occurrence of thrombosis in patients with congenital bleeding disorders represents an exceptional event. Hemophilia A and hemophilia B patients have been showed to present both arterial and venous thrombosis (85 cases of arterial thrombosis and 34 cases of venous thrombosis). The great majority of arterial thrombosis are myocardial infarction or other acute coronary syndromes, whereas the majority of venous thrombosis are deep vein thrombosis and/or pulmonary embolisms. However there are discrepancies in the proportion of arterial and venous thrombosis seen in hemophilia A versus hemophilia B. The ratio of arterial versus venous thrombosis in hemophilia A is 3.72 whereas that for hemophilia B is 1.12. This indicates that arterial thrombosis is more frequent in hemophilia A as compared to hemophilia B and the opposite is true for venous thrombosis. The potential significance of this discrepancy is discussed.

    Venous thromboembolism (VTE) is a leading cause of morbidity and mortality worldwide. However, the mechanisms by which clots are formed in the deep veins have not been determined. Tissue factor (TF) is the primary initiator of the coagulation cascade and is essential for hemostasis. Under pathological conditions, TF is released into the circulation on small-membrane vesicles termed microparticles (MPs). Recent studies suggest that elevated levels of MPTF may trigger thrombosis. This review provides an overview of the role of TF in VTE. PMID:20690821

    Full Text Available Venous thromboembolism (VTE, consisting of deep vein thrombosis and pulmonary embolism, is a major clinical concern associated with significant morbidity and mortality. The cornerstone of management of VTE is anticoagulation, and traditional anticoagulants include parenteral heparins and oral vitamin K antagonists. Recently, new oral anticoagulant drugs have been developed and licensed, including direct factor Xa inhibitors (e.g. rivaroxaban, apixaban and edoxaban and thrombin inhibitors (e.g. dabigatran etexilate. This narrative review focusses on the characteristics of these direct anticoagulants and the main results of published clinical studies on their use in the prevention and treatment of VTE.

    Chronic venous insufficiency of the lower limbs is very prevalent. In recent decades, Doppler ultrasound has become the method of choice to study this condition, and it is considered essential when surgery is indicated. This article aims to establish a method for the examination, including venous mapping and preoperative marking. To this end, we review the venous anatomy of the lower limbs and the pathophysiology of chronic venous insufficiency and explain the basic hemodynamic concepts and the terminology required to elaborate a radiological report that will enable appropriate treatment planning and communication with other specialists. We briefly explain the CHIVA (the acronym for the French term "cure conservatrice et hémodynamique de l'insuffisance veineuse en ambulatoire"=conservative hemodynamic treatment for chronic venous insufficiency) strategy, a minimally invasive surgical strategy that aims to restore correct venous hemodynamics without resecting the saphenous vein.

    Full Text Available Insertion of central venous port (CVP catheter in the cancer population is associated with increased incidence of venous thromboembolic events (VTE. However, trials have shown limited benefit of antithrombotic treatment to prevent catheter-related venous thrombosis. This prospective observational cohort study was designed to assess the incidence of VTE closely related to CVP implantation in patients with cancer and undergoing chemotherapy, and to identify a high risk subgroup of patients. Between February 2006 and December 2011, 1097 consecutive cancer patients with first CVP implantation were included. Catheter-related VTE were defined as deep venous thrombosis in the arm, with or without pulmonary embolism (PE, or isolated PE. The incidence of CVP-associated VTE was 5.9% (IC95 4.4–7.3% at 3 months, and 11.3% (IC95 9.4–13.2% at 12 months. The incidence of any VTE was 7.6% (IC95 6.0–9.3% at 3 months, and 15.3% (IC95 13.1–17.6% at 12 months. High Khorana risk score and lung cancer were significant predictors of 3 month VTE. In conclusion, this large cohort study of patients with first CVP catheter implantation confirms the high incidence of VTE associated with the CVP implantation and allow identifying high risk patients who may benefit from thromboprophylaxis.

    Diet plays an important role in modulating the risk of arterial and venous thrombosis. Several lines of evidence attest that consumption of fish and its compounds, especially omega-3 fatty acids, may be effective to decrease the cardiovascular risk. Since the pathogenesis of arterial and venous thrombosis share some common aspects, we performed a systematic review of published clinical studies that investigated the association between fish intake and venous thrombosis. An electronic search was carried out in Medline, Scopus, and ISI Web of Science using the key words "fish" OR "seafood" AND "venous thromboembolism" OR "deep vein thrombosis" OR "pulmonary embolism", with no language or date restriction. Overall, 6 studies (5 prospective and 1 case-control) were finally identified. In only 1 small case-control study, a larger intake of total fish was found to be negatively associated with the risk of venous thromboembolism. No association was found in 4 large prospective studies, whereas a positive association was observed in the remaining. No substantial difference was also noticed between intake of fatty or lean fish. Taken together, the current epidemiological evidence does not support the existence of a significant effect of total fish consumption on the risk of venous thromboembolism. PMID:25962392

    Chronic venous ulcer can often be associated with asymptomatic peripheral arterial disease (PAD), which usually remains undiagnosed adding significantly to the morbidity of these patients. The Ankle-Brachial Pressure Index (ABPI) is suggested for PAD evaluation. Many PAD studies were conducted in western countries, but there is a scarcity of data on the prevalence of PAD in clinical venous ulcer patient in developing countries. We conducted a study in a tertiary care hospital of eastern part of India to find out the prevalence of PAD in venous ulcer patients, and also to find the sensitivity of ABPI as a diagnostic tool in these patients. We evaluated clinically diagnosed patients with venous ulcer using ABPI and Colour Doppler study for the presence of PAD. Possible associations such as age, sex, body mass index (BMI), smoking, hypertension and atherosclerosis were studied. All results were analysed using the software Statistica version 6. PAD was present in 23 (27·71%) patients. Older age, longer duration, smoking, high BMI and hypertension were found to be significantly associated with PAD. A very strong level of agreement was found between venous Doppler and ABPI. Assessment for the presence of PAD is important in all clinically diagnosed venous ulcer patients. ABPI being a simple, non-invasive outpatient department (OPD)-based procedure, can be routinely used in cases of venous ulcer to find out the hidden cases of PAD even in developing countries.

    Summary: To further investigate the vertical transmission route of human papillomavirus (HPV) and the indication for the choice of mode of delivery, the infective status of 152 asymptomatic pregnant wemen and the maternal-fetal transmission were studied. By using general primers in polymerase chain reaction (GP-PCR) combined with restriction fragment length polymorphism analysis, HPV DNA positive rate in cervical secretions and venous blood in asymptomatic pregnant women was 36.21 % and 52.78 %, respectively, and the identified genotypes were mainly HPV16 and 18. The maternal-fetal transmission rate of HPV via genital tract as well as blood was 40.91 % and 57.89 %, respectively. It was concluded that besides the transmission route of genital tract and amniotic fluid, there was also transplacental transmission of HPV in utero. Therefore,in our opinion, it is not an absolut indication to perform a cesarean delivery for the pregnant women with HPV asymtomatic genital infection.

    Full Text Available Atrial fibrillation (AF is a common and refractory arrhythmia. Prevalence of AF increases with age. Asymptomatic AF is a state of asymptomatic episodes of arrhythmia and its exact prevalence remains unknown. Ablation and therapy with antiarrhythmic agents may predispose to asymptomatic AF. Detection of silent AF is crucial for prevention of ischaemic stroke. Progress in continuous ECG monitoring by Holter ECG, telemetry methods or implantable devices can provide a useful tools for identifying silent AF. Simple screening procedures like pulse examination and ambulatory ECG may be helpful in arrhythmia detection and logically – ischemic stroke prevention.

  18. Radionuclide plethysmography and Tc-99m red blood cell venography in venous thrombosis: comparison with contrast venography

    International Nuclear Information System (INIS)

    Radionuclide plethysmography (RPG) is a new technique that uses Tc-99m labelled red blood cells to ascertain changes in venous volumes by detecting the change in counts in response to the inflation and deflation of proximal thigh cuffs. Diagnosis of ileofemoral venous occlusion is possible using this technique, which also provides kinetic data of venous outflow. A range of normal values was defined in 19 subjects for per cent change in venous capacitance and venous outflow. Twenty-one patients with suspected deep venous thrombosis were studied prospectively using RPG, radionuclide venography (RV), and contrast venography (CV) to establish the usefulness of RPG alone and in combination with RV in the diagnosis of deep venous thrombosis. RPG proved to be a reliable technique for the diagnosis of ileofemoral venous thrombosis (sensitivity, 91%; specificity, 100%). RV was less sensitive (73%) and less specific (93%) in diagnosing that condition. When RPG is used as the criterion for the detection of ileofemoral vein thrombosis and RV is used as the criterion for the detection of calf vein thrombosis, the combined techniques show improved sensitivity (92%) and specificity (93%) for the detection of all deep venous thromboses

    The prevalence of kidney stones is increasing worldwide. Asymptomatic non-obstructing kidney stones are increasingly detected as an incidental finding on radiologic imaging, which has been performed more frequently over the last decades. Beside the current interventional treatment modalities such as extracorporeal shockwave lithotripsy (ESWL), ureterorenoscopy (URS) and percutaneous nephrolithotomy (PNL), active surveillance of asymptomatic kidney stones has been a focus of discussion lately, not only for attending physicians, but even more so for patients. The current German and European guidelines recommend active surveillance for patients with asymptomatic kidney stones if no interventional therapy is mandatory because of pain or medical factors. Herein we review the current literature on risks and benefits of active surveillance of asymptomatic non-obstructing kidney stones. PMID:26378390

    Full Text Available Cerebral sinus venous thrombosis (CSVT is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment.

    Deep vein thrombosis and pulmonary embolism is a well-recognised major health problem in the West. There is a deep-rooted belief among clinicians that deep vein thrombosis is rare in Asians, particularly in the Chinese population. However, it appears that the incidence of venous thrombosis and pulmonary embolism is increasing in Chinese patients. Prophylaxis reduces the incidence of venous thrombosis by 66% and of pulmonary embolism by 50%Ը? prophylaxis should therefore be considered for Chin...

    Henriet, J P

    1992-01-01

    According to D. Reinharez, pain and edema are the commonest presenting symptoms in phlebology. Pain is one of the most classical symptoms of an ordinary deep venous thrombosis, a valuable feature when present, in the form of deep tension, heaviness, swelling and a feeling of dead weight. It is often absent or slight. It may consist merely of a dull cramp, or of an "undefinable" (C. Bourde) odd, heavy leg. It generally affects the calf but may involve the sole of the foot, the heel, the thigh, the groin or even the true pelvis. This feeling, although "imprecise and variable" (P. Wallois, P. Griton) is highly suggestive. It increases on standing and walking in the form of unilateral uncomfortable tension, heaviness or painful swelling, which maybe a source of worry or even anxiety to the patient. Tenderness on palpation of venous tracts and their stretching is more suggestive. In the opinion of M. Duruble, Neuhof's sign (feeling of tender fullness of the calf) is more reliable than Homans' sign (pain in the calf caused by passive dorsiflexion of the foot, with the lower limb in extension) which essentially stretches only the posterior tibial venous system. The value of Sigg's sign (pain in the popliteal fossa on passive extension of the knee) is controversial. Far more rare is phlegmasia coerulea dolens or Grégoire's blue leg, complicating phlegmasia alba dolens or of sudden onset, with initial very severe or even "intolerable" pain (J.J. Pinot) in Scarpa's triangle, rapidly spreading to the limb. In varicose phlebitis (M. Perrin) or superficial thrombophlebitis or varico-phlebitis (A.A. Ramelet) or superficial venitis (J.P. Henriet), pain most often consists of moderate burning tension overlying the thrombosed vein(s), increased by palpation and mobilisation. Sometimes severe initially, it is exacerbated by the slightest touch. In total, pain, regardless of its characteristics, its site and/or its severity, is one of the most constant clinical features of venous

    Full Text Available Chronic venous insufficiency (CVI leads to skin changes with dermal hemosiderin deposition. We studied the presence of hemosiderin in the urine to assess if this could be used as a biochemical marker for CVI. Hereby we present a case control study conducted in a tertiary care centre in South India. There were 100 cases with evidence of advanced CVI (the Clinical-Etiology-Anatomy-Pathophysiology classification: C5, C6 confirmed by duplex scanning. Controls were 50 patients with leg ulcers due to other etiologies. All patients were subjected to urinary hemosiderin testing. In all 100 patients with CVI (C5 and C6 disease axial venous reflux was confirmed by duplex ultrasound. Superficial venous reflux was noted in 71% of patients and deep venous reflux in 54.%. Primary venous insufficiency was the etiology in 81% of patients. Only 4/100 patients had detectable amounts of hemosiderin in the urine. Urine hemosiderin testing to determine presence or absence of CVI yielded the following values: positive predictive value-80%; negative predictive value-33%; sensitivity-4% and specificity-98%. The test could not be recommended as a marker of CVI. In Indian patients urinary hemosiderin is not a useful screening test in CVI.

    Full Text Available Paolo PrandoniDepartment of Cardiothoracic and Vascular Sciences, Thromboembolism Unit, University Hospital of Padua Padua, ItalyAbstract: An increasing body of evidence suggests the likelihood of a link between venous and arterial thrombosis. The two vascular complications share several risk factors, such as age, obesity, diabetes mellitus, blood hypertension, hypertriglyceridemia, and metabolic syndrome. Moreover, there are many examples of conditions accounting for both venous and arterial thrombosis, such as the antiphospholipid antibody syndrome, hyperhomocysteinemia, malignancies, infections, and the use of hormonal treatment. Finally, several recent studies have consistently shown that patients with venous thromboembolism are at a higher risk of arterial thrombotic complications than matched control individuals. We, therefore, speculate the two vascular complications are simultaneously triggered by biological stimuli responsible for activating coagulation and inflammatory pathways in both the arterial and the venous system. Future studies are needed to clarify the nature of this association, to assess its extent, and to evaluate its implications for clinical practice.Keywords: venous thromboembolism, deep vein thrombosis, pulmonary embolism, myocardial infarction, ischemic stroke, atherosclerosis

The selection criteria were high-quality studies and studies relevant to clinical reproductive medicine. Summaries were presented and discussed...... is associated with an inherited thrombophilia in men and women. Changes in the coagulation system and in the risk of clinical VTE in women also occur during pregnancy, with the use of reproductive hormones and as a consequence of ovarian stimulation when hyperstimulation syndrome and conception occur together...... therapy (HRT) increases the VTE risk 2- to 4-fold. There is a synergistic effect between thrombophilia and the various reproductive risks. Prevention of VTE during pregnancy should be offered to women with specific risk factors. In women who are at high risk, CHC and HRT should be avoided. CONCLUSIONS...

    Full Text Available Background: Erectile dysfunction is an important problem in men and an organic cause is found in about 50% of cases. When a vasculogenic etiology is suspected, imaging assessments are of great help. Cavernosography is traditionally recognized as an imaging modality for evaluation of venous leakage in men with impotency. We employed CT cavernosography as a novel technique for demonstrating penile venous anatomy and leaking veins.Methods: In the present case series study, we recruited 45 patients with erectile dysfunction by convenient sampling at Hazrat Rasoul Akram Hospital in Tehran, Iran, during one year (1390. The patients had previously been diagnosed with venous incompetency by Doppler study. After intracavernosal injection of prostaglandin E1, we injected sterile normal saline into the corpora cavernosa to achieve penile erection. Later, we injected contrast media into the corpus cavernosum, which was followed by CT scan of the penis and pelvic area to show the venous anatomy and leakage sites.Results: The mean age of the patients was 35.8±8.9 years. 36 (80% patients had venous leakage in crural veins, 27 (60% in cavernosal veins, 27 (60% in circumflex veins, 24 (52.3% in urethral veins, 21 (46.7% in deep dorsal vein, 3 (6.7% in para-arterial veins and 3 (6.7% in corpus spongiosum. Conclusion: The results of this study show the high prevalence of venous leakage in patients referring for erectile dysfunction. Moreover, CT cavernosography was shown to be a useful method for evaluating penile venous system and its related leakage sites which are important for surgical planning.

    Turner syndrome is well known to be associated with significant cardiovascular abnormalities. This paper studied the incidence of cardiovascular abnormalities in asymptomatic adolescent patients with Turner syndrome using multidetector computed tomography (MDCT) instead of echocardiography. Twenty subjects diagnosed with Turner syndrome who had no cardiac symptoms were included. Blood pressure and electrocardiography (ECG) was checked. Cardiovascular abnormalities were checked by MDCT. According to the ECG results, 11 had a prolonged QTc interval, 5 had a posterior fascicular block, 3 had a ventricular conduction disorder. MDCT revealed vascular abnormalities in 13 patients (65%). Three patients had an aberrant right subclavian artery, 2 had dilatation of left subclavian artery, and others had an aortic root dilatation, aortic diverticulum, and abnormal left vertebral artery. As for venous abnormalities, 3 patients had partial anomalous pulmonary venous return and 2 had a persistent left superior vena cava. This study found cardiovascular abnormalities in 65% of asymptomatic Turner syndrome patients using MDCT. Even though, there are no cardiac symptoms in Turner syndrome patients, a complete evaluation of the heart with echocardiography or MDCT at transition period to adults must be performed.

    The traditional view that multiple sclerosis (MS) is an autoimmune disease has recently been challenged by the claim that MS is caused by chronic cerebrospinal venous insufficiency (CCSVI). Although several studies have questioned this vascular theory, the CCSVI controversy is still ongoing. Our...... aim was to assess the prevalence of CCSVI in Danish MS patients using sonography and compare these findings with MRI measures of venous flow and morphology....

  18. Asymptomatic cerebral hemorrhage detected by MRI

    International Nuclear Information System (INIS)

    Detection of previous cerebral infarction on CT films of patients with no history of stroke is a common occurrence. The incidence of silent cerebral infarction was reported to be about 10 to 11 percent, but very few reports concerning asymptomatic cerebral hemorrhage available. However, recent clinical application of MRI has resulted in the detection of old asymptomatic hemorrhage in patients with no history known stroke-like episodes. The purpose of this study was to elucidate the incidence, the cause and the character of the asymptomatic cerebral hemorrhage among patients who had undergone MRI examinations. From September 1987 through June 1990, 2757 patients have undergone 3474 MR scans of the brain with 1.0 Tesla Siemens Magneton unit in our hospital. Seventeen patients showed no clinical signs or symptoms suggesting a stroke episode corresponding to the detected hemorrhagic lesion. The 17 patients corresponded to 0.6% of the patients who underwent MRI, 1.5% of the patients with cerebrovascular disease and 9.5% of the patients with intracerebral hemorrhage(ICH), which was rather higher than expected. Among the 17 patients, 12 were diagnosed as primary ICH and 5 as secondary ICH. Most of the primary asymptomatic hemorrhage were hypertensive ones and slit-like curvilinear lesions between the putamen and claustrum or external capsule. The secondary asymptomatic hemorrhage were due to AVM and angiomas in the frontal cortex, thalamus and pons. (author)

    {sup 99m}Tc-DI-DD3B6/22-80B3 (ThromboView registered, hereafter abbreviated to {sup 99m}Tc-DI-80B3 Fab') is a radiolabelled humanised monoclonal Fab' fragment with affinity and specificity for D-dimer domains of cross-linked fibrin. Detection of thromboembolic events has been demonstrated in canine models. The study objectives were evaluation of safety and characterisation of biodistribution, immunogenicity and pharmacokinetic profile of increasing doses of {sup 99m}Tc-DI-80B3 Fab' in subjects with acute lower-limb DVT. Twenty-six patients with acute lower limb DVT were enrolled. Of these, 21 received a single intravenous dose of 0.5 mg (n = 6), 1.0 mg (n = 9) or 2 mg (n = 6) {sup 99m}Tc-DI-80B3 Fab'. Blood and urine samples and gamma camera images were collected to 24 h after administration for pharmacokinetic and dosimetry analysis. Vital signs, electrocardiography, hematological and biochemical data and human anti-human antibody (HAHA) levels were monitored for up to 30 days following administration. Patients were assigned to either planar or single photon emission computed tomographic (SPECT) imaging of the thorax at 4 h following injection. Thirty-five adverse events were reported in 15 of the 21 subjects. Those deemed possibly related to administration of {sup 99m}Tc-DI-80B3 Fab' included mild hypertension, mild elevation of LD (lactate dehydrogenase) and moderate elevation of ALT (alanine transaminase). HAHA assays remained negative. Pharmacokinetics and organ dosimetry were comparable to prior normal volunteer data. Localisation of Thromboview registered to sites of known thrombus was evident as early as 30 min post-injection. In subjects with acute DVT, {sup 99m}Tc-DI-80B3 Fab' was well tolerated with favourable characteristics for the detection of acute venous thrombosis. (orig.)

    Direct imaging of pulmonary embolism (PE) and deep vein thrombosis (DVT) with CT, and potentially with MR, will continue to replace V/Q scintigraphy. Venous imaging with MR far detecting DVT is used in a few centers, and their published accuracy figures are impressive. Recent studies of MR pulmonary angiography for PE reported that sensitivity of MRA was 85-100%, specificity 95-96%, but this data must be confirmed in other centers and patient populations. MR has advantages compared with CT, which make it worthwhile to continue MR development. Ionizing radiation and iodinated contrast material are not used. Imaging the pulmonary arteries and then imaging whichever venous region is of clinical interest is practical in a single examination. Repeated examinations can be performed safely. New contrast materials will facilitate the practically and accuracy of the MR technique and perfusion imaging may increase sensitivity. MR also has disadvantages compared with CT. It does not image effectively the non-vascular compartment of the lungs. It is more expensive, patient monitoring is more cumbersome, and a routine technique, which embodies all of MR's potential advantages, has not been packaged and tested. Accordingly, helical CT is a realistic option in clinical management of patients with suspected PE in most centers, while clinical application of MR is limited to centers with appropriate MR expertise and technology. However, MR has a number of fundamental characteristics that make it potentially ideal modality for evaluating patients with suspected acute venous thromboembolic disease and further clinical research with MRA is warranted.

  2. Asymptomatic cerebral lesions and risk factors in normal individuals

    International Nuclear Information System (INIS)

    We studied the relationship between asymptomatic ischemic lesions on magnetic resonance imaging (MRI) and risk factors for stroke in 460 asymptomatic subjects. Focal lesions were classified into two groups according to their size. Periventricular hyperintensity (PVH) was graded from 0 to 3. We also evaluated equivocal deep white matter hyperintensity as a confluent lesion that was separate from PVH. The incidence of focal lesions below 2 mm in diameter (we regard them as etatcrible) was 5.7%, and that of lesions over 2 mm was 16.1%. Grade 2 PVH was observed in 12.6% and grade 3 PVH in 2.2%. The prevalence rate of confluent lesions was 8.7%. The age of the group which had white matter lesions was significantly higher than that of the group without lesions. Hypertension was the greatest risk factor for the occurrence of focal lesions, PVH, and confluent lesions. Diabetes mellitus was a significant risk factor only for focal lesions. Other risk factors did not display any relations to white matter abnormalities. (author)

This study was performed to determine the incidence of asymptomatic bacteriuria and pyuria in pregnant women. A total of 86 pregnant women during first trimester and 56 nonpregnant women were evaluated. All subjects were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine samples were collected for both groups. Urine samples were examined microscopically and were cultured. Bacteriological examination revealed asymptomatic bacteriuria in 25 (29.1% and 3 (5.4% of the study group and controls, respectively (P < 0.05. Microscopic analysis of urine revealed pyuria in 18 (20.9% and 3 (5.4% of the study group and controls, respectively (P < 0.05. In study group, Escherichia coli were found in 20%, Staphylococcus epidermidis in 36%, Staphylococcus haemolyticus in 12%, streptococcus group D in 12%, Staphylococcus saprophyticus in 12% and Proteus mirabilis in 8%. In control group, E. coli were found in 33.3% and S. epidermidis in 66.7%. Our results show that the incidence of asymptomatic bacteriuria is significantly higher in pregnant women than nonpregnant women. The main finding in the present study was that 29.1% of the pregnant women who were in first trimester had asymptomatic bacteriuria which is much higher than figures reported from other countries. The use of microscopic urinanalysis was not an effective method of detecting asymptomatic bacteriuria and urine culture is necessary for screening these pregnant women.

  6. Asymptomatic Esophageal Varices Should Be Endoscopically Treated

    Full Text Available Endoscopic treatment has generally been accepted in the management of bleeding esophageal varices. Both the control of acute variceal bleeding and elective variceal eradication to prevent recurrent bleeding can be achieved via endoscopic methods. In contrast to acute and elective treatment, the role of endoscopic therapy in asymptomatic patients who have never had variceal bleeding remains controversial because of the rather disappointing results obtained from prophylactic sclerotherapy. Most published randomized controlled trials showed that prophylactic sclerotherapy had no effect on survival. In some studies, neither survival rate nor bleeding risk was improved. In this article, the author champions the view that asymptomatic esophageal varices should be endoscopically treated.

    Antithrombin Cambridge II(A384S) mutation shows a relatively high frequency in western population. Some studies suggest that the mutation is an independent genetic risk factor both for deep vein thrombosis (DVT) and for arterial thrombosis, but whether the mutation has racial difference or has a general significance for thrombophilia remains unclear. In this study we performed an analysis of the prevalence of the mutation in Chinese southern population; Also, the antithrombin activity levels were evaluated in each investigated individual. The studies included 120 patients with DVT, 150 patients with cerebral infarction, and 110 controls. The mutation was detected using polymerase chain reaction/PvuII restrictive fragment length polymorphism procedures. Antithrombin activity assay was done using chromogenic substrate method. The results showed that no antithrombin Cambridge II mutation was detected in all three groups (DVT, cerebral infarction and controls), the incidence was 0/380. Plasma antithrombin activity was 91.37% +/- 16.15% in the DVT patients and 102.68% +/- 13.10% in the controls; the antithrombin activity was significantly reduced in the DVT group (P Cambridge II mutation has a racial difference, and may not be a valuable risk factor of thrombophilia in Asian population, and antithrombin deficiency remains a major genetic risk factor for DVT patients in China.

In addition, the radiologic approach is discussed. This was a retrospective analysis of 19 children with CVT. The children were examined by contrast-enhanced dynamic CT. Radiologic findings were correlated with the etiology of CVT. Cerebral venous thrombosis is not as infrequent in children as has been thought. Cerebral venous thrombosis in children can occur due to trauma (n=9), infections (n=7), or coagulation disorders (n=3). Extent and location of thrombosis, as well as complications, final outcome, and therapy, depend on the etiology. Computed tomography remains a valuable primary imaging modality in the diagnosis of CVT in the acutely injured or diseased child. (orig.)

    Full Text Available Introduction. Controversy remains over the optimal length of anticoagulation following idiopathic venous thromboembolism. We sought to determine if a longer, finite course of anticoagulation offered additional benefit over a short course in the initial treatment of the first episode of idiopathic venous thromboembolism. Data Extraction. Rates of deep venous thrombosis, pulmonary embolism, combined venous thromboembolism, major bleeding, and mortality were extracted from prospective trials enrolling patients with first time, idiopathic venous thromboembolism. Data was pooled using random effects meta-regression. Results. Ten trials, with a total of 3225 patients, met inclusion criteria. For each additional month of initial anticoagulation, once therapy was stopped, recurrent venous thromboembolism (0.03 (95% CI: −0.28 to 0.35; =.24, mortality (−0.10 (95% CI: −0.24 to 0.04; =.15, and major bleeding (−0.01 (95% CI: −0.05 to 0.02; =.44 rates measured in percent per patient years, did not significantly change. Conclusions: Patients with an initial idiopathic venous thromboembolism should be treated with 3 to 6 months of secondary prophylaxis with vitamin K antagonists. At that time, a decision between continuing with indefinite therapy can be made, but there is no benefit to a longer (but finite course of therapy.

    Full Text Available The radial forearm free flap (RFFF has been widely used with increasing frequency in head and neck reconstruction following extirpative surgery. The controversy of the venous anastomoses patterns still exists. Thus, we conducted a meta-analysis to assess the relationship between the venous anastomoses patterns and venous compromise.MEDLINE, PubMed, Web of Science, and Wanfang databases were searched for studies reporting the different venous anastomoses patterns of the RFFF. A meta-analysis was conducted using the random effects models. Publication bias and sensitivity analysis were also assessed.6 studies with 992 cases were included in this meta-analysis. The dual anastomosis group tended to have a lower incidence of venous compromise (RR = 1.39. However, the difference was not statistically significant (95%CI: 0.59, 3.24.This meta-analysis indicated that performing dual venous anatomoses consisting of superficial and deep systems conferred a tendency of the reduction with regard to venous compromise.

    To examine neuropsychological deficits associated with the human immunodeficiency virus (HIV), 25 asymptomatic homosexual men and sexual partners of intravenous drug users and 25 seronegative homosexual men and nonhigh-risk heterosexuals were assessed on measures of fine motor control, visual scanning, attention, depression, and global psychological functioning. Analysis suggested that HIV infection is associated with reduced fine motor control. Seropositivity is associated with elevated depression and global psychological maladjustment. When depression and global adjustment were analyzed as covariates, motor slowing was evident in the seropositive group. These findings suggest an association between motor slowing and HIV infection in asymptomatic subjects and point to the necessity of measuring affect at least as a control variable. Further study is needed to determine whether the fine motor deficit evident in this sample is limited to distinct subgrouping of the over-all sample. PMID:2762096

  2. Treatment approaches to asymptomatic follicular lymphoma.

    2013-12-01

    Follicular lymphoma is a heterogeneous disease in which some patients present an indolent evolution for decades and others, a rather aggressive form of the disease requiring immediate therapy. While immunochemotherapy has emerged as a standard of care for symptomatic patients, treatment of the asymptomatic population remains controversial. Since the disease is still considered incurable, delayed initiation of therapy is an acceptable option. However, four single injections of rituximab can result in an acceptable clinical response and can improve the duration of the interval without cytotoxic therapy. With recent therapeutic approaches that enable substantial improvements in life expectancy for follicular lymphoma patients, limiting short- or long-term treatment toxicities appears as a new concern in the asymptomatic population. Based on these options, the challenge is to preserve patient quality of life and prolong survival: from the patient's perspective, his/her opinion is therefore of significant importance.

  3. Cerebral blood flow in asymptomatic individuals

    International Nuclear Information System (INIS)

    We studied the relationship between cortical grey matter flow (CBF) and age, cerebrovascular risk factors and the severity of subcortical hypersignals (HS, hyperintensity score in MRI) in 47 asymptomatic subjects with cerebrovascular risk factors. Multiple regression analysis revealed that HS was most strongly related to CBF, and that hematocrit, age and evidence of ischemic change detected in the electrocardiogram also appeared to be independent determinants of CBF. Both the severity and location of hypersignals were correlated with CBF. The most significant negative correlation observed was that between CBF and HS in the basal ganglia-thalamic region, where the degree of signal abnormality was modest. Decreased CBF in asymptomatic subjects with cerebrovascular risk factors may be related to microcirculatory disturbance associated with elevated hematocrit and an increase in the number of risk factors, and functional suppression of cerebral cortex due to the neuronal disconnection associated with subcortical lesions. In addition, impaired cerebral circulation may be related to MRI signal abnormalities. (author)

    We report a case of intra-abdominal testicular torsion, of eight years old boy who presented with asymptomatic left impalpable testis. Diagnostic laparoscopy revealed a twisted small intra-abdominal testis in which the spermatic cord twisted 3 times over a band attached to the internal ring. The cord was long enough to bring the small testis into the scrotal sac. This case highlights the pole of laparoscopy in the management of impalpable testes.

    Ulcerative colitis (UC) is an idiopathic autoimmune inflammatory disease of the gastrointestinal tract. Cerebral venous sinus thrombosis along with deep vein thrombosis, pulmonary embolism and arterial thrombosis have occasionally been reported as a complication in the active phase of UC being attributed to its pro-thrombotic state. This paper depicts a 38-year-old female with a history of UC in remission who developed sudden onset headache, blurring of vision and seizures. Subsequent diagnosis of cerebral venous sinus thrombosis was made with MRI venography and treated with low molecular weight heparin with complete resolution of symptoms. The highlights of this case underscore the importance of evaluating cerebral venous sinus thrombosis as a cause of acute onset neurological deterioration in a setting of inflammatory bowel disease. It also emphasizes on the hypothesis that the risk of venous thrombosis or other hypercoagulable states have no direct relationship with the disease activity or flare-up. PMID:27437291

    Full Text Available This cross-sectional study is conducted to determine the prevalence of asymptomatic cervical spine subluxation in rheumatoid arthritis patients by plain radiographs and its relation to demographic and clinical characteristics, disease activity measures and medications. 100 rheumatoid arthritis patients (18 male and 82 female were selected randomly, according to the American college of Rheumatology Criteria, who were under follow up in the rheumatology clinic. A complete history was taken, and physical examination has been done with focus on the cervical spine to determine their demographic data, disease duration, age of disease onset, drug history, swollen and tender joint counts, and ESR, Hb, CRP, RF levels. The disease activity of patients with rheumatoid arthritis was measured using the disease activity score 28. Radiographs of the cervical spine included lateral views taken in flexion, extension, neutral position of the neck and anterioposterior and odontoid projection view. Asymptomatic cervical spine subluxation was found in 17 of the 100 patients (17%. The prevalence of, anterior atlantoaxial subluxation, atlantoaxial impaction and subaxial subluxation was 10(10%, 5(5% and 6(6%, respectively. Posterior subluxation was not detected. The only characteristic that showed meaningful relationship with cervical spine subluxation was CRP (P=0.036. Our results showed that patients with RA, who have cervical spine subluxation cannot be distinguished on the basis of symptoms. Cervical spine involvement is common and may be asymptomatic, indicating routine cervical spine imaging is needed in patients with RA.

    Management guidelines were created to screen and manage asymptomatic renal stones in U.S. astronauts. The true risk for renal stone formation in astronauts due to the space flight environment is unknown. Proper management of this condition is crucial to mitigate health and mission risks. The NASA Flight Medicine Clinic electronic medical record and the Lifetime Surveillance of Astronaut Health databases were reviewed. An extensive review of the literature and current aeromedical standards for the monitoring and management of renal stones was also done. This work was used to develop a screening and management protocol for renal stones in astronauts that is relevant to the spaceflight operational environment. In the proposed guidelines all astronauts receive a yearly screening and post-flight renal ultrasound using a novel ultrasound protocol. The ultrasound protocol uses a combination of factors, including: size, position, shadow, twinkle and dispersion properties to confirm the presence of a renal calcification. For mission-assigned astronauts, any positive ultrasound study is followed by a low-dose renal computed tomography scan and urologic consult. Other specific guidelines were also created. A small asymptomatic renal stone within the renal collecting system may become symptomatic at any time, and therefore affect launch and flight schedules, or cause incapacitation during a mission. Astronauts in need of definitive care can be evacuated from the International Space Station, but for deep space missions evacuation is impossible. The new screening and management algorithm has been implemented and the initial round of screening ultrasounds is under way. Data from these exams will better define the incidence of renal stones in U.S. astronauts, and will be used to inform risk mitigation for both short and long duration spaceflights.

    2016-06-01

    Venous thromboembolism (VTE) is a major health concern because it increases morbidity and mortality after a surgical procedure. A number of well-defined, evidence-based guidelines are available delineating suitable use of prophylaxis to prevent deep vein thrombosis and pulmonary embolism. Despite the available literature, there are clear gaps between recommendations and clinical practice, affecting the incidence of VTE. Plastic surgeons underuse the substantiated literature and risk stratification tools that are available to decrease the incidence of VTE in the office-based surgical setting because of fear of bleeding or hematoma complications postoperatively. Venous thromboembolism creates an economic burden on both the patient and the healthcare system. The intent of this literature review is to determine existing VTE risk using assessment models available to aid in the implementation of protocols for VTE prevention, specifically for high-risk cosmetic surgical patients in office-based settings.

  16. The Paradigm Shift to Non-Treatment of Asymptomatic Bacteriuria

    2016-01-01

    Asymptomatic bacteriuria, also called asymptomatic urinary infection, is a common finding in healthy women, and in women and men with abnormalities of the genitourinary tract. The characterization and introduction of the quantitative urine culture in the 1950s first allowed the reliable recognition of asymptomatic bacteriuria. The observations that a substantial proportion of patients with chronic pyelonephritis at autopsy had no history of symptomatic urinary infection, and the high frequency of pyelonephritis observed in pregnant women with untreated asymptomatic bacteriuria, supported a conclusion that asymptomatic bacteriuria was harmful. Subsequent screening and long term follow-up programs for asymptomatic bacteriuria in schoolgirls and women reported an increased frequency of symptomatic urinary tract infection for subjects with asymptomatic bacteriuria, but no increased morbidity from renal failure or hypertension, or increased mortality. Treatment of asymptomatic bacteriuria did not decrease the frequency of symptomatic infection. Prospective, randomized, comparative trials enrolling premenopausal women, children, elderly populations, patients with long term catheters, and diabetic patients consistently report no benefits with antimicrobial treatment of asymptomatic bacteriuria, and some evidence of harm. Several studies have also reported that antimicrobial treatment of asymptomatic bacteriuria increases the short term risk of pyelonephritis. Current investigations are exploring the potential therapeutic intervention of establishing asymptomatic bacteriuria with an avirulent Escherichia coli strain to prevent symptomatic urinary tract infection for selected patients.

  17. Radionuclide plethysmography and Tc-99m red blood cell venography in venous thrombosis: comparison with contrast venography

    International Nuclear Information System (INIS)

    Radionuclide plethysmography (RPG) is a new technique that uses Tc-99m labelled red blood cells to ascertain changes in venous volumes by detecting the change in counts in response to the inflation and deflation of proximal thigh cuffs. Diagnosis of ileofemoral venous occlusion is possible using this technique, which also provides kinetic data of venous outflow. Twenty-one patients with suspected deep venous thrombosis were studied prospectively using RPG, radionuclide venography (RV), and contrast venography (CV) to establish the usefulness of RPG alone and in combination wth RV in the diagnosis of ileofemoral venous thrombosis (sensitivity, 91%; specificity, 100%). RV was less sensitive (73%) and less specific (93%) in diagnosing that condition

    2014-01-01

    Full Text Available Thirty seven year old asymptomatic male underwent routine medical examination which revealed an abnormal mass in the right atrium. Family history was not suggestive of any cardiac or malignant disease. Detailed investigation detected deficiency of protein S, which is a vitamin K dependent protein and a cofactor for activated protein C mediated cleavage of factor Va and VIIIa. The deficiency of protein S predisposes to venous thrombosis. Further investigation revealed that it was an organized calcified thrombus in right atrium occupying almost whole of the cavity. Various approaches including surgical excision, thrombolysis and anticoagulation has been used to manage such thrombosis. However therapeutic approach is still a question of debate. Atriotomy and excision of mass was done using cardiopulmonary bypass.

    Full Text Available To determine the prevalence of asymptomatic urinary abnormalities in adolescents, first morning clean mid-stream urine specimens were obtained from 2500 individuals and examined by dipstick and light microscopy. Adolescents with abnormal screening results were reexamined after two weeks and those who had abnormal results twice were subjected to systemic clinical examination and further clinical and laboratory investigations. Eight hundred and three (32.1% individuals had urinary abnormalities at the first screening, which significantly decreased to 345 (13.8% at the second screening, (P <0.001. Hematuria was the most common urinary abnormalities detected in 245 (9.8% adolescents who had persistent urine abnormalities; 228 (9.1% individuals had non glomerular hematuria. The hematuria was isolated in 150 (6% individuals, combined with leukocyturia in 83 (3.3% individuals, and combined with proteinuria in 12 (0.5% individuals. Leukocyturia was detected in 150 (6% of all studied adolescents; it was isolated in 39 (1.6% individuals and combined with proteinuria in 28 (1.1% of them. Asymp- tomatic bacteriuria was detected in 23 (0.9% of all studied adolescents; all the cases were females. Proteinuria was detected in 65 (2.6% of all the studied adolescents; 45 (1.8% indivi- duals had <0.5 g/day and twenty (0.8% individuals had 0.5-3 g/day. Asymptomatic urinary abnormalities were more common in males than females and adolescents from rural than urban areas (P <0.01 and (P <0.001, respectively. The present study found a high prevalence of asymptomatic urinary abnormalities among adolescents in our population.

    To evaluate the efficacy and safety of radiologic venous port placement in children under venous anesthesia. Between April 2009 and July 2011, 44 ports were implanted in 41 children (24 boys, 17 girls). The age of patients ranged from 9 months to 19 years (mean, 6.5 years) and their body weights ranged from 6.8 kg to 56.3 kg (mean, 23.2 kg). Right internal jugular vein access was used in 42 ports, right subclavian vein in 1, and left subclavian in 1. Durability and complications of port implantation were reviewed. The technical success rate was 100%. The catheter life was 10-661 days (mean 246 days). Two patients died during the follow-up period, 21 and 6 ports were removed at the end of treatment or as a result of complications, respectively. One port was removed and replaced by a Hickmann catheter. Three ports were explanted due to port-related sepsis, one due to a catheter kink, and two for unexplained fever or insertion site pain. The overall port-related infection was 3 cases (6.8%, 0.28/1000 catheter days). Venous port placement by interventional radiologists in children under intravenous sedation is relatively safe, with a high rate of technical success and low rate of complications.

    Indwelling central venous catheters have been reported to increase the risk of superior venous cava (SVC) syndrome. This case report describes the development of acute SVC syndrome in a 28-year-old woman with end-stage renal disease implanted with a left-side hemodialysis reliable outflow graft and a right-side double lumen hemodialysis catheter via internal jugular veins. Her symptoms were not alleviated after catheter removal and systemic anticoagulation therapy. She was eventually treated with catheter-directed thrombolysis and a predischarge computer tomographic venogram on postthrombolytic procedure day 7 showed patent central veins and patient remained asymptomatic. This case demonstrates that catheter-directed thrombolysis can be safely employed to treat refractory catheter-induced acute SVC syndrome in end-stage renal disease patients.

    Intracranial developmental venous anomalies (DVAs) are considered benign vascular dispositions; they are asymptomatic in the vast majority of cases. They represent extreme variations of the venous drainage and may rarely be responsible for focal venous ischemia leading to neurological dysfunction. The aim of the study is to analyze a group of patients with symptomatic DVAs with capillary stain at angiography. We retrospectively reviewed the clinical and radiological features of patients in which a DVA was considered the cause of a neurological event. In all the patients, the DVA was suspected by angio-CT or MRI and conventional angiography was performed to detail the angioarchitecture of the DVA. A total of 7 patients and 11 DVAs were identified; three patients had multiple DVAs. Three DVAs were frontal, two were parietal, two were thalamic, one was in the midbrain, and three were cerebellar. Patients presented with progressive neurological deficits, seizures, or cerebral hemorrhage. All these DVAs were associated with a peculiar capillary stain at angiography. Although being normal anatomical variations, DVAs may create, because of hemodynamic unbalance, venous ischemia that induces angiogenic phenomena. MRI shows the suffering of the brain and angiography witnesses this angiogenesis under the form of capillary stain. Conventional angiography can thus provide useful information to recognize ''atypical'' symptomatic DVAs. (orig.)

    2016-08-01

    An increase in the diagnosis of pulmonary embolus (PE) in the early postoperative period has been attributed to the use of multidetector 64-slice computed tomographic (CT) scans. It was suspected that this finding was the result of marrow or fat emboli that are commonly associated with arthroplasty rather than a true venous thromboembolic phenomenon. The purpose of this study was to determine the baseline pulmonary findings in asymptomatic patients after total joint arthroplasty (TJA). Over a 1-year period, an institutional review board-approved prospective study of 20 asymptomatic patients using a multidetector 64-slice CT scanner was performed. Overall, 15 TKAs and 5 total hip arthroplasties were included for analysis. All of the CT scans were negative for PE. There were no signs of microemboli or fat emboli on any scan. No patient went on to develop a PE at 2 years postoperatively. Despite the fact that emboli are created during TJA, if emboli are seen on a CT scan postoperatively, they should be assumed to be real events with clinical sequelae. If pulmonary symptoms develop postoperatively, they should not simply be assumed to be the result of fat or marrow embolism.

  7. Sepsis, venous return, and teleology.

    An understanding of heart-circulation interaction is crucial to our ability to guide our patients through an episode of septic shock. Our knowledge has advanced greatly in the last one hundred years. There are, however, certain empirical phenomena that may lead us to question the wisdom of our prevailing treatment algorithm. Three extreme but iatrogenically possible haemodynamic states exist. Firstly, inappropriately low venous return; secondly, overzealous arteriolar constriction; and finally, misguided inotropy and chronotropy. Following an unsuccessful fluid challenge, it would be logical to first set the venous tone, then set the cardiac rate and contractility, and finally set the peripheral vascular resistance. It is hypothesized that a combination of dihydroergotamine, milrinone and esmolol should be superior to a combination of noradrenaline and dobutamine for surviving sepsis. PMID:25245463

    Full Text Available Abstract Background CMV-induced vasculopathy and thrombosis have been reported, but they are rare conditions usually encountered in immunocompromised patients. However more and more complications of CMV infections are recognized in immunocompetent patients. Case presentation We present a case report of a previously healthy adult with cytomegalovirus infection that was complicated by tibiopopliteal deep venous thrombosis and in whom Factor V Leiden heterozygous mutation was found. Conclusion This new case report emphasizes the involvement of cytomegalovirus in induction of vascular thrombosis in patients with predisposing risk factors for thrombosis. It is necessary to screen for CMV infection in patients with spontaneous thrombosis and an history of fever.

    Cerebral venous thrombosis (CVT) is an uncommon cause of stroke with extremely diverse clinical features, predisposing factors, brain imaging findings, and outcome. Anticoagulation is the cornerstone of CVT management, however, it is not supported by high-quality evicence. Novel oral anticoagulants (NOACs) have been extensively studied in patients with deep vein thrombosis, pulmonary embolism and non-valvular atrial fibrillation. The aim of our work was to review the available evidence for NOACs in the treatment of CVT. Based on our literature search there is insufficient evidence to support the use of NOACs in CVT, although case series with rivaroxaban and dabigatran have showed promising results. PMID:25994451

    No studies have compared toileting-specific behaviors of encopretic children with those of asymptomatic children and have controlled for environmental factors such as parental attitudes, parenting styles, and bathroom facilities. This study prospectively examined the toileting habits of 86 chronically encopretic children compared with those of 27 asymptomatic siblings and 35 asymptomatic nonsiblings. Although encopretic children experienced significantly more soiling than did controls, the total number of daily bowel movements passed in the toilet (+/-SD) was comparable in the three groups (.92 +/- .76 in encopretic children compared with 1.14 +/- .43 and 1.08 +/- .47 in siblings and nonsiblings, respectively). Encopretic children experienced pain with defecation more often than did controls. During the 14-day study period, encopretic children complained of pain on 2.75 +/- 4.03 days compared with .58 +/- 1.84 days among sibling controls and 2.31 +/- 3.21 days among nonsibling controls. The mean pain score in encopretic children was .76 +/- 1.00 compared with .05 +/- .15 and .26 +/- .38 among siblings and nonsiblings, respectively. All three groups of children sat on the toilet without parental prompting the same number of times each day. In summary, children with chronic encopresis do not seem to avoid toileting, and they exhibit toileting behaviors that are very similar to those of asymptomatic siblings as well as to those of nonsibling controls.

    To determine the prevalence of asymptomatic urinary abnormalities in adolescents, first morning clean mid-stream urine specimens were obtained from 2500 individuals and examined by dipstick and light microscopy. Adolescents with abnormal screening results were reexamined after two weeks and those who had abnormal results twice were subjected to systemic clinical examination and further clinical and laboratory investigations. Eight hundred and three (32.1%) individuals had urinary abnormalities at the first screening, which significantly decreased to 345 (13.8%) at the second screening, (P adolescents who had persistent urine abnormalities; 228 (9.1%) individuals had non glomerular hematuria. The hematuria was isolated in 150 (6%) individuals, combined with leukocyturia in 83 (3.3%) individuals, and combined with proteinuria in 12 (0.5%) individuals. Leukocyturia was detected in 150 (6%) of all studied adolescents; it was isolated in 39 (1.6%) individuals and combined with proteinuria in 28 (1.1%) of them. Asymptomatic bacteriuria was detected in 23 (0.9%) of all studied adolescents; all the cases were females. Proteinuria was detected in 65 (2.6%) of all the studied adolescents; 45 (1.8%) individuals had adolescents from rural than urban areas (P adolescents in our population.

    Full Text Available Introduction. Syphilis is a sexually transmitted disease that is known as “the great imitator” due to its wide variety of clinical presentations, including ocular disorders. There has been an increase in the rate of syphilis in the United States, especially in persons with HIV. We report a case of optic perineuritis in an asymptomatic male secondary to central nervous system (CNS syphilis. Case Report. A 41-year-old man was found to have bilateral disc edema on a routine exam. Brain MRI was unremarkable, and lumbar puncture revealed a normal opening pressure, with an elevated cerebrospinal fluid white cell count. Orbit MRI showed optic nerve sheath expansion and enhancement, consistent with optic perineuritis. He tested positive for syphilis based on serum RPR and FTA-ABS. Conclusion. Ophthalmologic findings, including disc edema, may be the presenting features of CNS syphilis. Even in asymptomatic persons, perineuritis should be considered early, as diagnosis and treatment are imperative given the progressive nature of the disease.

    Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep venous thrombosis (DVT), is a common and severe complication of critical illness. Although well documented in the general population, the prevalence of PE is less known in the ICU, where it is more difficult to diagnose and to treat. Critically ill patients are at high risk of VTE because they combine both general risk factors together with specific ICU risk factors of VTE, like sedation, immobilization, vasopressors or central venous catheter. Compression ultrasonography and computed tomography (CT) scan are the primary tools to diagnose DVT and PE, respectively, in the ICU. CT scan, as well as transesophageal echography, are good for evaluating the severity of PE. Thromboprophylaxis is needed in all ICU patients, mainly with low molecular weight heparin, such as fragmine, which can be used even in cases of non-severe renal failure. Mechanical thromboprophylaxis has to be used if anticoagulation is not possible. Nevertheless, VTE can occur despite well-conducted thromboprophylaxis.

    Objective To explore the early diagnosis of lower extremity deep venous thrombosis (LDVT)and evaluate the therapeutic effect of anticoagulant therapy in hospitalized patients with acute ischemic stroke. Methods According to Wells model for suspecting lower extremity deep venous thrombosis,patients with suspected LDVT were confirmed by compression ultrasonography. If the patients diagnosed with LDVT had no contraindications to anticoagulant therapy,they were treated with low molecular weight heparin(LMWH)subcutaneous injection and oral warfarin at the same time.The dosage of oral warfarin was determined by Roberts'age adjusted warfarin loading protocol.LMWH was stopped when the patients'international normalized ratio(INR)was 2.0~3.0 for two consecutive days. Results From January 2003 to August 2007,2067 cases with acute ischemic stroke were admitted to the department of neurology in Huizhou Municipal Central Hospital including 18 cases with LDVT and the incidence was 0.9%.The patients with LDVT all had paralytic extremities including 13 left legs and 5 right legs with deep vein thrombosis.All the 18 cases were treated by anticoagulant including 17 cases with oral warfarin treatment for 3 months.Symptoms in all LDVT patients were eliminated.12 cases had been observed for one year and 5 cases for three months after they stopped taking warfatin.There were no patients with pulmonary thromboembolism and LDVT recurrence. Conclusions By using Wells model for suspecting LDVT,patients with acute ischemic stroke-complicated LDVT can be timely diagnosed.The goal of prompt and enough anticoagulant can be achieved according to Roberts'age adjusted warfarin loading protocol.Because of racial difference,population difference and other unknown factors,the incidence of acute ischemic stroke patients with complicated LDVT is much lower in Huizhou.It suggests that it should be unnecessary to use LMWH in patients with acute ischemic stroke to prevent LDVT in Huizhou.%目的 探

    Human brucellosis is mainly caused by contact with Brucella-infected animals and their secretions and carcasses. Individuals who are continuously in contact with animals are considered to be at a high risk but only some show symptoms and are diagnosed as cases of brucellosis. Here, we showed that asymptomatic brucellosis infections occur among humans. Asymptomatic infections mainly result from less frequent contact with Brucella and/or contact with low-virulence Brucella. In our study, patients with asymptomatic infection had low antibody titres and different contact patterns. Awareness of asymptomatic infection is important for early diagnosis of brucellosis and prevention of chronic infection.

    Association between chronic venous disease and obesity has recently been studied, with indications that it may worsen in obese patients. The aim of study was to correlate clinical classes of chronic venous disease according to Clinical Etiology Anatomy Pathophysiology (CEAP) classification and body mass index, as well as to compare the severity of chronic venous disease in obese and nonobese patients. This retrospective cross-sectional prevalence study was conducted at the Maringá State University and Belczak Vascular Center along a period of 2 years, consisting of a random sample of 482 patients with complaints compatible with chronic venous disease. Data obtained from patient's files included gender, age, weight and height (for calculating body mass index), and clinical class (C) of chronic venous disease according to CEAP classification. Statistical analysis included Spearman's correlation coefficient, Chi-square test (for comparing frequencies), and Student's t-test (for comparing means). Significant positive correlation between body mass index and clinical classes was established for women (0.43), but not for men (0.07). Obesity (body mass index  : ≥  : 30.0) was significantly more frequent in patients with chronic venous disease in clinical classes 3 (p venous disease in clinical class 1 (p venous disease in women, but not in men. It also corroborated the negative impact of obesity on the clinical severity of chronic venous disease.

    @@ Venous thromboembolism (VTE), composed of deep venous thrombosis (DVT) and pulmonary thromboembolism (PTE), has been recognized as worldwide health problem not only in the western countries but also in Asian-Pacific regions. Tremendous progress has been made in recent years in identifying the potential risk factors, understanding the pathogenesis and developing therapeutic approaches for VTE. However, most of the currently available data are from American and European populations. Limited data from Chinese population are validated. Efforts should be made to increase public awareness, and promote clinical and translational research of VTE in modern China.

    There are various region-specific challenges to the diagnosis and effective treatment of venous thromboembolism in Latin America. Clear guidance for physicians and patient education could improve adherence to existing guidelines. This review examines available information on the burden of pulmonary embolism and deep vein thrombosis in Latin America and the regional issues surrounding the diagnosis and treatment of pulmonary embolism and deep vein thrombosis. Potential barriers to appropriate care, as well as treatment options and limitations on their use, are discussed. Finally, an algorithmic approach to the diagnosis and treatment of venous thromboembolism in ambulatory patients is proposed and care pathways for patients with pulmonary embolism and deep vein thrombosis are outlined for primary care providers in Latin America.

    Three-quarters of the estimated 390 million dengue virus (DENV) infections each year are clinically inapparent. People with inapparent dengue virus infections are generally considered dead-end hosts for transmission because they do not reach sufficiently high viremia levels to infect mosquitoes. Here, we show that, despite their lower average level of viremia, asymptomatic people can be infectious to mosquitoes. Moreover, at a given level of viremia, DENV-infected people with no detectable symptoms or before the onset of symptoms are significantly more infectious to mosquitoes than people with symptomatic infections. Because DENV viremic people without clinical symptoms may be exposed to more mosquitoes through their undisrupted daily routines than sick people and represent the bulk of DENV infections, our data indicate that they have the potential to contribute significantly more to virus transmission to mosquitoes than previously recognized.

    Full Text Available Intracranial lipomas are rarely observed, and accepted as the congenital lesion of central nervous system. Intracranial lipomas are usually based centrally and have benign character. In the brain, it is mostly localized in pericallosal region, quadrigeminal system, and suprasellar region and cerebellopontine angles. As being mostly asymptomatic, the patients occasionally constitute clinical symptoms according to localization area. These symptoms are systemic symptoms such as cephalalgia, drowsiness, crisis and ataxy. In this article, we aimed to present the intracranial lipomas phenomenon which was diagnosed to have caused ptosis and upper lateral sight problem, namely causing localized neurological symptom, situated in mesencephalon and having pressure effect, regarding a 57-year old male patient brought to the emergency service with the nausea, throwing up and cephalalgia ailments.

    2016-06-26

    A 78-year-old asymptomatic woman was referred to our clinic for a second opinion regarding indication for mitral valve surgery. An echocardiogram showed a moderate mitral stenosis with a concomitant severe regurgitation. The most striking feature, however, was a giant left atrium with a parasternal anteroposterior diameter of 79 mm and a left atrial volume index of 364 mL/m². There are various echocardiographic definitions of a giant left atrium, which are mainly based on measurements of the anteroposterior diameter of the left atrium using M-mode in the parasternal long axis view. Since the commonly accepted method for echocardiographic evaluation of left atrial size is left atrial volume index, we propose a cut-off value of 140 mL/m(2) for the definition of a "giant left atrium".

    Objective. To determine the postoperative appearance of the plantar fascia on MR imaging after a fasciotomy has been performed, and to compare the postsurgical appearance of the fascia after an open and endoscopic procedure.< rate at head-abs-p1.lf>Design and patients. Fifteen asymptomatic volunteers (12 women, 3 men; age range 22-49 years, mean age 33 years) with prior fasciotomies for treatment of longstanding plantar fasciitis were studied. Fourteen volunteers had a unilateral release and one volunteer had bilateral releases, allowing for assessment of 16 ankles. Eight fasciotomies were performed through an open incision and eight were performed endoscopically. The average time between surgery and imaging was 24 months (range 11-46 months). The site of surgery was established from the operative reports. Proton density (PD)-weighted and T2-weighted images in three orthogonal planes were obtained on a 1.5-T magnet. In eight studies, T1-weighted sagittal and STIR sagittal images were included. The fascia in each ankle was assessed for morphology and signal intensity. Perifascial soft tissues and bone marrow were assessed for edema. Preoperative MR studies were available in five volunteers.< rate at head-abs-p1.lf>Results. There was no apparent difference in the postoperative appearance of the ankle after an open or endoscopic procedure except for scar formation in the subcutaneous fat which was common after an open procedure (P<0.05). Three ankles had a gap in the fascia (one open, two endoscopic). The plantar fascia measured a mean of 7.0 mm (range 5-10 mm) at the fasciotomy, and 8.3 mm (range 6-12 mm) at the enthesis. At the fasciotomy, 11 of 13 ankles had an indistinct deep contour and 9 of 13 had an indistinct superficial contour. At the enthesis, 13 of 16 ankles had an indistinct deep contour and 6 of 16 had an indistinct superficial contour. Compared with preoperative MR studies there was an average reduction in the fascial thickness at the enthesis of 14

    Venous thromboembolism (VTE), which is manifested as deep vein thrombosis (DVT) and pulmonary embolism (PE), represents a significant cause of death, disability, and discomfort. They are frequent complications of various surgical procedures. The aging population and the survival of more severely injured patients may suggest an increasing risk of thromboembolism in the trauma patients. Expanded understanding of the population at risk challenges physicians to carefully examine risk factors for VTE to identify high-risk patients who can benefit from prophylaxis. An accurate knowledge of evidence-based risk factors is important in predicting and preventing postoperative DVT, and can be incorporated into a decision support system for appropriate thromboprophylaxis use. Standard use of DVT prophylaxis in a high-risk trauma population leads to a low incidence of DVT. The incidence of VTE is common in Asia. The evaluation includes laboratory tests, Doppler test and phlebography. Screening Doppler sonography should be performed for surveillance on all critically injured patients to identify DVT. D-Dimer is a useful marker to monitor prophylaxis in trauma surgery patients. The optimal time to start prophylaxis is between 2 hours before and 10 hours after surgery, but the risk of PE continues for several weeks. Thromboprophylaxis includes graduated compression stockings and anticoagulants for prophylaxis. Anticoagulants include Warfarin, which belongs to Vitamin K antagonists, unfractionated heparin, low molecular weight heparins, factor Xa indirect inhibitor Fondaparinux, and the oral IIa inhibitor Melagatran and ximelagatran. Recombinant human soluble thrombomodulin is a new and highly effective antithrombotic agent. Prophylactic placement of vena caval filters in selected trauma patients may decrease the incidence of PE. The indications for prophylactic inferior vena cava filter insertion include prolonged immobilization with multiple injuries, closed head injury, pelvic

    Summary Background Data: The epidemiology of venous thromboembolism (VTE) after cancer surgery is based on clinical trials on VTE prophylaxis that used venography to screen deep vein thrombosis (DVT). However, the clinical relevance of asymptomatic venography-detected DVT is unclear, and the population of these clinical trials is not necessarily representative of the overall cancer surgery population. Objective: The aim of this study was to evaluate the incidence of clinically overt VTE in a wide spectrum of consecutive patients undergoing surgery for cancer and to identify risk factors for VTE. Methods: @RISTOS was a prospective observational study in patients undergoing general, urologic, or gynecologic surgery. Patients were assessed for clinically overt VTE occurring up to 30 ± 5 days after surgery or more if the hospital stay was longer than 35 days. All outcome events were evaluated by an independent Adjudication Committee. Results: A total of 2373 patients were included in the study: 1238 (52%) undergoing general, 685 (29%) urologic, and 450 (19%) gynecologic surgery. In-hospital prophylaxis was given in 81.6% and postdischarge prophylaxis in 30.7% of the patients. Fifty patients (2.1%) were adjudicated as affected by clinically overt VTE (DVT, 0.42%; nonfatal pulmonary embolism, 0.88%; death 0.80%). The incidence of VTE was 2.83% in general surgery, 2.0% in gynecologic surgery, and 0.87% in urologic surgery. Forty percent of the events occurred later than 21 days from surgery. The overall death rate was 1.72%; in 46.3% of the cases, death was caused by VTE. In a multivariable analysis, 5 risk factors were identified: age above 60 years (2.63, 95% confidence interval, 1.21–5.71), previous VTE (5.98, 2.13–16.80), advanced cancer (2.68, 1.37–5.24), anesthesia lasting more than 2 hours (4.50, 1.06–19.04), and bed rest longer than 3 days (4.37, 2.45–7.78). Conclusions: VTE remains a common complication of cancer surgery, with a remarkable proportion

    静脉血栓栓塞症(venous thromboembolism,VTE)是一种多种危险因子共同参与其发病机制的全身性疾病,VTE最终产生两种主要的临床类型,包括深静脉血栓形成(deep venous thrombosis,DVT)和肺血栓栓塞症(pulmonary thromboembolism,PTE),前者最为常见,而后者则较为严重。作为一种疾病的两种表现,DVT与PTE的防治方法相似,主要为抗凝治疗。文章就近年来内科住院患者静脉血栓栓塞症临床防治的相关研究进展进行阐述。%Venous thromboembolism (venous thromboembolism, VTE) is a systemic disease which multiple risk factors involved in the pathogenesis, VTE finally produced two major clinical types, including deep venous thrombosis (deep venous thrombosis, DVT) and pulmonary thromboembolism (pulmonary thromboembolism, PTE), The former is most common, While the latter is more serious. As two kinds of manifestations of one disease, the preventive treatments of DVT and PTE are similar, mainly for anticoagulation therapy. This article reviews the related research progress about clinical prevention of venous thromboembolism in hospitalized medical patients.

  12. The relationship between brain atrophy and asymptomatic cerebral lesions

    International Nuclear Information System (INIS)

    In order to clarify the relationship between brain atrophy and asymptomatic cerebral lesions, total of 235 subjects (130 males and 105 females), who had neither neurologic deficits nor organic lesions on cerebral computed tomography, were studied. The subjects' ages ranged from 40 to 86 years (mean 66). They were divided into two groups: 90 controls without hypertension or diabetes mellitus (Group C), and 145 patients with essential hypertension (Group H). Brain atrophy was diagnosed using the caudate head index (CHI). Asymptomatic cerebral lesions on magnetic resonance imaging were defined as asymptomatic lacunae and white matter lesions. Caudate head index was higher in Group H than it was in Group C, and CHI in both groups was significantly correlated with the number of asymptomatic lacunae and the severity of white matter lesions on magnetic resonance imaging. These results indicate that brain atrophy may progress along with asymptomatic cerebral lesions. (author)

    Full Text Available Aim: To estimate the incidence of VTE in Indonesian patients undergoing major orthopedic surgery and not receiving thromboprophylaxis.Methods: This was an open clinical study of consecutive Indonesian patients undergoing major orthopedic surgery, conducted in 3 centers in Jakarta. Bilateral venography was performed between days 5 and 8 after surgery to detect the asymptomatic and to confi rm the symptomatic VTE. These patients were followed up to one month after surgery.Results: A total of 17 eligible patients were studied, which a median age of 69 years and 76.5% were females. Sixteen out of the 17 patients (94.1% underwent hip fracture surgery (HFS. The median time from injury to surgery was 23 days (range 2 to 197 days, the median duration of surgery was 90 minutes (range 60 to 255 minutes, and the median duration of immobilization was 3 days (range 1 to 44 days. Thirteen out of the 17 patients were willing to undergo contrast venography. A symptomatic VTE was found in 9 patients (69.2% at hospital discharge. Symptomatic VTE was found in 3 patients (23.1%, all corresponding to clinical signs of DVT and none with clinical sign of PE. These patients were treated initially with a low molecular weight heparin, followed by warfarin. Sudden death did not occur up to hospital discharge. From hospital discharge until 1-month follow-up, there were no additional cases of symptomatic VTE. No sudden death, bleeding complication, nor re-hospitalization was found in the present study.Conclusion: The incidence of asymptomatic (69.2% and symptomatic (23.1% VTE after major orthopedic surgery without thromboprophylaxis in Indonesian patients (SMART and AIDA, and still higher than the results of the Western studies. A larger study is required to establish the true incidence, and more importantly, that the use of thromboprophylaxis in these patients is warranted.

    The aim of this study is to declare our experience and to identify the important factors that influence the mortality and morbidity in patients with combat-related penetrating wounds of the abdomen (CR-PWA) with major venous vessel injuries. Twenty-six wounded with combat-related injuries of major abdominal venous vessels, admitted in the University Clinic cardiovascular surgery department during the period from 1 August 1991 through 30 October 1995, were analyzed. Patients with concomitant injured arteries and extra-abdominal injuries (n=150; 85.2%) were excluded from this study. The Penetrating Abdominal Trauma Index (PATI) score for each patient was calculated. Fifteen patients (57.69%) sustained with PATI score greater than 25 died. The mean duration of hospitalization was 16 days (range 0-86). The average hospitalization time for those surviving their complications was 17 days with a PATI of 25 or less, and 43 days with a score more than 25. Three clinical assessments of the long-term outcome were performed after a median of about 3, 5 and 10 years, respectively. Surviving patients (42.31%) were symptom free and had normal Duplex scans as well as no other surgical related complications. Higher PATI scores, postoperative complications and reoperations exert an unfavorable effect on patient outcome. PMID:18006557

    Full Text Available Abstract Venous thromboembolism is a common disease that is associated with considerable morbidity if left untreated. Recently, low-molecular-weight heparins (LMWHs have been evaluated for use in acute treatment of deep venous thrombosis and pulmonary embolism. Randomized studies have shown that LMWHs are as effective as unfractionated heparin in the prevention of recurrent venous thromboembolism, and are as safe with respect to the occurrence of major bleeding. A pooled analysis did not show substantial differences among different LMWH compounds used, but no direct comparison of the different LMWHs is currently available. Finally, in patients with pulmonary embolism, there is a relative lack of large studies of daily practice. It could be argued that large prospective studies, in patients who were treated with LMWHs from the moment of diagnosis, are needed.

    2016-01-01

    Introduction: Management guidelines were created to screen and manage asymptomatic renal stones in U.S. astronauts. The risks for renal stone formation in astronauts due to bone loss and hypercalcuria are unknown. Astronauts have a stone risk which is about the same as commercial aviation pilots, which is about half that of the general population. However, proper management of this condition is still crucial to mitigate health and mission risks in the spaceflight environment. Methods: An extensive review of the literature and current aeromedical standards for the monitoring and management of renal stones was done. The NASA Flight Medicine Clinic's electronic medical record and Longitudinal Survey of Astronaut Health were also reviewed. Using this work, a screening and management algorithm was created that takes into consideration the unique operational environment of spaceflight. Results: Renal stone screening and management guidelines for astronauts were created based on accepted standards of care, with consideration to the environment of spaceflight. In the proposed algorithm, all astronauts will receive a yearly screening ultrasound for renal calcifications, or mineralized renal material (MRM). Any areas of MRM, 3 millimeters or larger, are considered a positive finding. Three millimeters approaches the detection limit of standard ultrasound, and several studies have shown that any stone that is 3 millimeters or less has an approximately 95 percent chance of spontaneous passage. For mission-assigned astronauts, any positive ultrasound study is followed by low-dose renal computed tomography (CT) scan, and flexible ureteroscopy if CT is positive. Other specific guidelines were also created. Discussion: The term "MRM" is used to account for small areas of calcification that may be outside the renal collecting system, and allows objectivity without otherwise constraining the diagnostic and treatment process for potentially very small calcifications of uncertain

  2. Asymptomatic cerebral infarction examined by magnetic resonance imaging (MRI)

    International Nuclear Information System (INIS)

    To find the real incidence and risk factors in asymptomatic cerebral infarction, a retrospective review was made on magnetic resonance (MR) images, which were obtained from 713 outpatients seen at the Geriatrics Research Institute Hospital between March and November of 1990. The criteria for asymptomatic cerebral infarction are: high signal intensity areas larger than 3 mm in diameter on T2-weighted image; no history of stroke; no neurological and psychological signs or symptoms with or without subjective symptoms. Symptomatic cerebral stroke was defined as stroke episodes associated with neurological signs and infarction lesions on CT or MR imaging. Of a total of 713 patients, 215 (30.2%) had symtomatic cerebral infarction and 384 (53.9%) had no cerebral lesions. The incidence of asymptomatic cerebral infarction increased with aging. Cerebral risk factors, i.e. hypertension, atrial fibrillation, and diabetes mellitus, were more significantly common in both symptomatic and asymptomatic groups than the normal control group. In the group of asymptomatic patients, T2-weighted images showed hyperintensity in the corona radiata in 60.9%, in the frontal lobe in 32.1%, in the semioval center in 28.8%, and in the basal ganglia in 23.7%. Periventricular hyperintensity was present in 124 of all 713 patients (17.4%). Common complaints in asymptomatic patients were headache (40.0%), dizziness (14.4%), and neck muscle contraction (9.8%). In conclusion, MR imaging may contribute to manage asymptomatic patients. (N.K.)

    To study the effectiveness of Doppler echography in the deep venous system of the lower limbs for deep venous thrombosis detection in patients suspected of having pulmonary thromboembolism. There were received 341 consecutive suspected pulmonary thromboembolism patients, all of whom were emergency room attended. All were submitted to CT pulmonary angiography in order to evaluate thrombus presence in the pulmonary tree. Without knowing the results of the previous exploration, we studied 301 of the patients using Doppler echography in deep venous system of the lower limbs in order to evaluate thrombus presence. In the group of CT-detected pulmonary thromboembolism patients, the percentage of Doppler echography-detected deep venous thrombosis was 46.3%, while in the group of non-detected patients this percentage decreased to 4.7%. Additional deep venous system exploration in clinically suspected pulmonary thiolcarbamate patients is useful, since it can increase the detection rate of venous thromboembolic disease, thereby leading to early treatment and prevention of the disease's manifestation in the lungs. Realization of Doppler echography is especially beneficial in those patients who exhibit no factors which predispose them to thromboembolic disease, as well as in patients who have previously had venous thrombosis. This exploration account for 4.7% of non-detected pulmonary embolism patients being added to the ranks of those with thromboembolic disease, an important percentage when taking into consideration the high pulmonary thromboembolism morbimortality rate.

    Objective To investigate the application value of ultrasonic vascular enhancement technology (VET) combined with panoramic ultrasound imaging (PUl) in the interventional treatment of acute deep venous thrombosis (ADVT)of lower limbs. Methods VET and PUl were used to detect 48 veins of lower limbs in 46 patients with ADVT of lower limbs during interventional procedures. The acquired images were compared with those obtained with 2D ultrasound, CDFI and DSA. Then the thrombolytic catheter was moved under dynamic monitoring of VET. Resalts VET could show catheter in the cavity and its top position, boundary contour of undissolved thrombus, small mural thrombus, vascular wall and ambient collateral circulation clearly with less artifacts and interferences. The image quality was better than that of 2D ultrasound and CDFI (P<0. 05). Compared with DSA, the coincident rate of VET with DSA was 87. 50% (42/48) for the diameter of the recanalized lumen of femoral vein in the same narrow portion tangent, of 2D ultrasound and CDFI with DSA was 37. 50% (18/48,x2=25. 60, P<0. 05). Panoramic images of VET were clear and informative. VET could show the movement of catheter in cavity clearly in dynamic conditions, and under its surveillance, the lateral hole of thrombolytic catheter was put to the vein that contained thrombus accurately. Conclusion VET combined with PUl has great clinical application value in the interventional treatment of ADVT of lower limbs.%目的 探讨超声血管增强技术(VET)联合全景超声成像(PUI)在下肢急性深静脉血栓(ADVT)介入治疗中的应用价值.方法 应用VET及PUI对46例接受下肢ADVT介入治疗患者的48侧下肢血管进行检查,将图像与二维超声及CDFI、DSA进行对比分析,并在VET动态监视下移动溶栓导管.结果 VET图像可清晰显示管腔内导管及其头端位置、未溶血栓边界轮廓、附壁小血栓、血管壁情况及周围侧支循环等,伪像和干扰减少,图像质量评

    Background Chronic obstructive pulmonary disease (COPD) has a variable natural history and not all individuals follow the same course. This study aimed to identify the prevalence and characteristics of asymptomatic COPD patients from a population-based survey in China.Methods A multistage cluster sampling strategy was used in a population from seven different provinces/cities. All residents (over 40 years old) were interviewed with a standardized questionnaire and spirometry.Post-bronchodilator forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) of less than 70% was defined as the diagnostic criterion of COPD. All COPD patients screened were divided into symptomatic group and asymptomatic group according to the presence or absence of chronic respiratory symptoms. Socio-demographic,personal and exposure variables were collected and analyzed.Results Among the 1668 patients who were diagnosed with COPD from the 25 627 sampling subjects, 589 (35.3%)were asymptomatic. The age, sex, body mass index (BMI),rural and urban distributions, smoking habit and education levels were similar in the two groups. A total of 64.7% of the asymptomatic patients had no comorbidities. Cardiovascular diseases and lung cancer were more common among symptomatic COPD patients than asymptomatic group.Asymptomatic COPD group were less likely to present with poor ventilation in the kitchen, a family history of respiratory disease and recurrent childhood cough. Asymptomatic COPD patients had significantly higher FEV1 (73.1% vs. 61.0%), FVC (91.9% vs. 82.0%), and a higher ratio of FEV1/FVC (62.9% vs.58.7%) (all P <0.001) than symptomatic group. More asymptomatic patients were underdiagnosed (91.9% vs.54.3%, P<0.001) than symptomatic patients.Conclusions This large population-based survey confirmed a high prevalence of asymptomatic COPD patients in China. More use of spirometry screening test may be important to the early detection of COPD.

    Hepatic venous outflow obstruction after piggyback liver transplantation is a very rare complication. An unusual mechanism aggravating it is reported. A 33-year-old man with end-stage hepatitis B liver cirrhosis underwent a piggyback orthotopic liver transplantation using a fullsize cadaveric graft. Two months after transplantation,he developed gross ascites refractory to maximal diuretic therapy. Doppler ultrasound showed patent portal and hepatic veins. Serial computed tomography scans revealed a hypoperfused right posterior segment of the liver which subsequently underwent atrophy. Hepatic venography demonstrated a high-grade stenosis with an element of torsion of venous drainage at the anastomosis. The stenosis was successfully treated with repeated percutaneous balloon angioplasty. The patient remained asymptomatic six months afterwards with complete resolution of ascites and peripheral edema. We postulate that liver allograft segmental hypoperfusion and atrophy may aggravate or result in a hepatic venous outflow problem by the mechanism of torsion effect. Percutaneous balloon angioplasty is a safe and effective treatment modality for anastomotic stenosis.

    Full Text Available The dural sinus thrombosis is an uncommon complication of a commonly done procedure of central venous catheterisation. We present a case of massive hemorrhagic venous infarct with gross cerebral edema due to dural sinus thrombosis along with right internal jugular vein thrombus. A 21-year-old male patient presented to the emergency department with fever and swelling of the right neck four days following discharge after his prior hospitalization two weeks ago for acute renal failure due to severe gastroenteritis, when he underwent hemodialysis through right internal jugular access. On presentation, he was conscious, with swelling on right side of the neck, which was diagnosed as right internal jugular vein occlusion. However, he rapidly dete-riorated and developed signs of raised intracranial pressure despite being on treatment with heparin. He was diagnosed as having massive hemorrhagic cerebral venous infarct with gross cerebral edema complicated with shift of the ventricles to the left due to dural sinus thrombosis. Despite emergency decompressive craniotomy, he succumbed in the next two days due to coning. Asymptomatic catheter-related thrombosis is frequent in the intensive care units, but major complications like retrograde extension into dural sinus causing thrombosis is rare. A high index of suspicion is required to diagnose this major catastrophe for an early and meaningful intervention.

    immunological mechanisms in asymptomatic skin sensitization might provide new insights into the natural history and treatment of respiratory allergy. RECENT FINDINGS: Research on asymptomatic skin sensitization is rare, and the present review unites previous studies with recent findings. It is a common...... positive skin test must be ruled out before allergen avoidance measures are initiated. SUMMARY: Surprisingly few papers exist on asymptomatic skin sensitization epidemiology and immunology, despite the intriguing question as to why symptoms do not develop in IgE-sensitized patients.

  13. Cerebral venous outflow and cerebrospinal fluid dynamics

    Full Text Available In this review, the impact of restricted cerebral venous outflow on the biomechanics of the intracranial fluid system is investigated. The cerebral venous drainage system is often viewed simply as a series of collecting vessels channeling blood back to the heart. However there is growing evidence that it plays an important role in regulating the intracranial fluid system. In particular, there appears to be a link between increased cerebrospinal fluid (CSF pulsatility in the Aqueduct of Sylvius and constricted venous outflow. Constricted venous outflow also appears to inhibit absorption of CSF into the superior sagittal sinus. The compliance of the cortical bridging veins appears to be critical to the behaviour of the intracranial fluid system, with abnormalities at this location implicated in normal pressure hydrocephalus. The compliance associated with these vessels appears to be functional in nature and dependent on the free egress of blood out of the cranium via the extracranial venous drainage pathways. Because constricted venous outflow appears to be linked with increased aqueductal CSF pulsatility, it suggests that inhibited venous blood outflow may be altering the compliance of the cortical bridging veins.

    One hundred and seven Hickman catheters for haemodialysis were inserted in 90 end-stage chronic renal failure patients, and were used for 1-448 days (median 45 days). Sixty-nine per cent of the patients were treated without any problem for 1-165 days (median 34 days). Clinically evident complications occurred in 44 catheters inserted in 28 patients, and included outflow obstruction (16.8% of the catheters) and thrombosis (13.1% of the catheters). However, many episodes of clotting or insufficient flow could be corrected by simple manoeuvres. Other less frequent complications were recorded: sepsis, mainly in patients with increased risk factors (4.1% of the catheters), laceration of the catheter (3.7%) and occasional cases of jugular-vein phlebitis, transient palsy of a vocal cord, haematoma of the wound, and bleeding of the cutaneous orifice. No clinical sign of subclavian or innominate-vein thrombosis was observed. Nevertheless, a prospective study conducted in 50 asymptomatic patients demonstrated a 12% rate of anomalies of the venous system, although two-thirds of these alterations were mild and had no consequence. When the present series is compared to the results obtained with currently available percutaneous haemodialysis catheters, it is concluded that the Hickman catheter is a safe, comfortable and efficient vascular access device.

  15. Upper Body Venous Compliance Exceeds Lower Body Venous Compliance in Humans

    1996-01-01

    Human venous compliance hypothetically decreases from upper to lower body as a mechanism for maintenance of the hydrostatic indifference level 'headward' in the body, near the heart. This maintains cardiac filling pressure, and thus cardiac output and cerebral perfusion, during orthostasis. This project entailed four steps. First, acute whole-body tilting was employed to alter human calf and neck venous volumes. Subjects were tilted on a tilt table equipped with a footplate as follows: 90 deg, 53 deg, 30 deg, 12 deg, O deg, -6 deg, -12 deg, -6 deg, O deg, 12 deg, 30 deg, 53 deg, and 90 deg. Tilt angles were held for 30 sec each, with 10 sec transitions between angles. Neck volume increased and calf volume decreased during head-down tilting, and the opposite occurred during head-up tilt. Second, I sought to cross-validate Katkov and Chestukhin's (1980) measurements of human leg and neck venous pressures during whole-body tilting, so that those data could be used with volume data from the present study to calculate calf and neck venous compliance (compliance = (Delta)volume/(Delta)pressure). Direct measurements of venous pressures during postural chances and whole-body tilting confirmed that the local changes in venous pressures seen by Katkov and Chestukhin (1980) are valid. The present data also confirmed that gravitational changes in calf venous pressure substantially exceed those changes in upper body venous pressure. Third, the volume and pressure data above were used to find that human neck venous compliance exceeds calf venous compliance by a factor of 6, thereby upholding the primary hypothesis. Also, calf and neck venous compliance correlated significantly with each other (r(exp 2) = 0.56). Fourth, I wished to determine whether human calf muscle activation during head-up tilt reduces calf venous compliance. Findings from tilting and from supine assessments of relaxed calf venous compliance were similar, indicating that tilt-induced muscle activation is

    Full Text Available CONTEXT: Alcoholism may interfere with nutritional status, but reports are often troubled by uncertainties about ingested diet and organ function, as well as by ongoing abuse and associated conditions. OBJECTIVE: To identify nutritional and body compartment changes in stable alcoholics without confounding clinical and dietetic variables, a prospective observational pilot study was designed. Three well-matched populations were considered: subjects with chronic alcoholic pancreatitis, alcoholics without visceral disease, and healthy never-drinking adults (controls. METHODS: Subjects (n = 60 were asymptomatic males with adequate diet, no superimposed disease or complication, and alcohol-free for at least 6 months. After exclusions, 48 patients were compared. Variables encompassed dietary recall, bioimpedance analysis, biochemical profile and inflammatory markers. Main outcome measures were body fat, lean body mass, serum lipids, C-reactive protein, and selected minerals and vitamins. RESULTS: Both alcoholic populations suffered from reduced lean body mass (P = 0.001, with well-maintained body fat.Magnesium was depleted, and values of vitamin D and B12 correlated with alcohol abuse. LDL and total cholesterol was increased in alcoholics without pancreatitis (P = 0.04, but not in those with visceral damage. C-reactive protein and serum amyloid A correlated with duration of excessive drinking (P = 0.01. CONCLUSIONS: Undernutrition (diminished lean body mass, risk of magnesium and vitamin deficiencies contrasted with dyslipidemia and increased cardiovascular risk. This second danger was masked during chronic pancreatitis but not in alcoholics without visceral disease. Further studies should focus special requirements of this population.

    Iliofemoral venous thrombosis is discussed and a technique of iliofemoral venous thrombectomy is presented. Operative phlebography is recommended. The personal recommendations of leading American vascular surgeons in treating the patient with acute iliofemoral venous thrombosis are presented. I recommend thrombectomy for phlegmasia cerulea dolens, and in previously healthy, young ambulatory patients with phlegmasia alba dolens who are seen within 48 hours following thrombosis and have failed to show clinical improvement after a trial of bed rest, elevation of the lower extremities, and intravenous heparin. The majority of patients seen with phlegmasia alba dolens will best be served with nonoperative treatment.

    The prime objective of this International Microgravity Laboratory (IML-1) investigation is to measure the bulk compliance (distensibility) of the veins in the lower leg before, during, and after spaceflight. It is of particular interest whether venous compliance over the range of both positive and negative transmural pressures (various states of venous distention and collapse) changes throughout the duration of spaceflight. Information concerning the occurrence and character of compliance changes could have implications for the design of improved antigravity suits and further the understanding of inflight and postflight venous hemodynamics.

    2016-02-01

    International guidelines advocate the use of first-line ultrasound for central venous catheter, particularly for the internal jugular vein. The role of ultrasound in peripheral venous access remains questionable. In some specific situations, such as pediatrics, obesity and patients with poor venous network, problems to cannulate peripheral vein may occur. Success rate of peripheral intravenous access increases with the diameter of the vein and for a depth of the vein between 0.3 and 1.5 cm. The type of puncture (long-axis or short-axis) and the type of catheters have little influence on the success rate. Specific considerations have to be taken concerning infection control.

    2016-01-01

    American cutaneous leishmaniasis (ACL) is a major public health problem caused by vector-borne protozoan intracellular parasites from the genus Leishmania, subgenera Viannia and Leishmania. Asymptomatic infection is the most common outcome after Leishmania inoculation. There is incomplete knowledge of the biological processes explaining the absence of signs or symptoms in most cases while other cases present a variety of clinical findings. Most studies of asymptomatic infection have been conducted in areas of endemic visceral leishmaniasis. In contrast, asymptomatic ACL infection has been neglected. This review is focused on the following: (1) epidemiological studies supporting the existence of asymptomatic ACL infection and (2) immunological studies conducted to understand the mechanisms responsible for controlling the parasite and avoiding tissue damage.

  4. Oral contraceptives and venous thrombosis: end of the debate?

    During the more than 30-year history of oral contraceptives, clinicians have received several official warnings issued by regulating agencies on cardiovascular risks. These have affected not only gynecological practice, but also generated research activities resulting in the refined third-generation products marketed in the 1970s. The alert sent out by the UK Committee on Safety of Medicines (CSM), October 1995, on increased risk of deep venous thrombosis during use of these compounds was, therefore, very much unexpected. The statements were referring to unpublished data and, thus, indicated new and highly alarming findings. However, during the following months, although four epidemiological studies reported a 2-4 fold relative increase compared with the second-generation oral contraceptives. This relative increase means, looking at absolute risks, an excess of 1-2 cases of deep venous thrombosis per 10,000 oral contraceptive users per year. In the academic discussions following the primary publication of the four papers, the possibility of confounding factors and bias was strongly emphasized and follow-up studies together with re-analysis of the original studies have not generated evidence for the suspicion of the increased risk with third-generation oral contraceptives. In contrast, a decreasing tendency was demonstrated for more serious events such myocardial infarction. Also, the biological plausibility for increased risk of deep venous thrombosis with third-generation products is lacking, although one study has pointed to a change in the natural anticoagulatory mechanism. Obviously, the authorities have a right to react on suspicion, but the psychological and social effects of the abrupt stopping of oral contraceptive use should not be ignored, and the public understanding of scientific results is manipulated by the mass media. Following confirmed evidence from both epidemiological and biological studies, with full acknowledgement of the contraceptive and non

    2013-09-01

    Full Text Available The strength of pedicle screws attachment to the vertebrae is an important factor affecting their motion resistance and long term performance. Low bone quality, e.g. in osteopenic patients, keeps the screw bone interface at risk for subsidence and dislocation. In such cases, bone cement could be used to augment pedicle screw fixation. But its use is not free of risk. Therefore, clinicians, especially spine surgeons, radiologists, and internists should become increasingly aware of cement migration and embolism as possible complications. Here, we present an instructive case of cement embolism into the venous system after augmented screw fixation with fortunately asymptomatic clinical course. In addition we discuss pathophysiology and prevention methods as well as therapeutic management of this potentially life-threatening complication in a comprehensive review of the literature. However, only a few case reports of cement embolism into the venous system were published after augmented screw fixation.

  7. The possibility for use of venous flaps in plastic surgery

    International Nuclear Information System (INIS)

    The use of venous flaps is controversial. The mechanism of perfusion of venous flaps is still not fully understood. The research was conducted on 56 white rats. In our experimental work we studied two different models of venous flaps: pedicled venous flap (PVF) and pedicled arterialized venous flap (PAVF). Our results showed that postoperative congestion was present in all flaps. However 66.7% of all pedicled venous flaps and 100% of all pedicled arterialized venous flaps eventually survived. Histological examination revealed that postoperatively the blood flow in the skin of the pedicled arterialized venous flap became «re-reversed» again; there were no differences between mechanism of survival of venous flaps and other flaps. On the 7-14th day in the skin of all flaps were processes of neoangiogenesis and proliferation. Hence the best scenario for the clinical use of venous flaps unfolds when both revascularization and skin coverage are required

    Full Text Available Background: With aging there is alteration of elastic properties of the skin and skin-blood flow. Aim: The purpose of this study was to compare age-related changes in selected biomechanical parameters of the skin (skin hardness, skin extensibility, relaxation time constant, τ and subcutaneous microcirculatory quality (SMQ in individuals with and without venous diseases. Materials and Methods: Two groups were studied: the first group was of asymptomatic healthy individuals and the second group included patients with chronic venous insufficiency (CVI and venous ulceration, without edema. Both groups were subdivided to three age categories (21-40, 41-60 and 61-90 years old. Skin hardness was measured by durometer, extensibility and τ were measured using extensometer and SQM was assessed via postural vasoconstrictive response (LDF. Results: Results showed that skin hardness, extensibility, and τ-values were increased, whereas LDF was decreased in the older groups as compared with younger groups. These changes are attributed to alterations in the skin structure and reduced capillaries density networks. Similar behavior was found in the biomechanical and microcirculatory changes in patients with venous ulceration and CVI, but these changes were more increased further in older patients with venous ulceration as compared with older patients with CVI and that can be attribute to more intense response against tissue injury. Conclusions: Since aging elevated skin hardness and extensibility, but lowered vasoconstrictive response in individuals, with and without, venous diseases, we conclude that aging process is likely to cause an accumulation of damaged skin tissues and that could induce an apparent antigen-driven response that altered skin structure and the subsequent biomechanical properties obtained in this study.

    Rotavirus is a major cause of infectious intestinal disease in young children; a substantial prevalence of asymptomatic infection has been reported across all age groups. In this study, the authors determined characteristics of asymptomatic rotavirus infection and potential risk factors for infection. Healthy persons were recruited at random from the general population of England during the Study of Infectious Intestinal Disease in England (1993-1996). Rotavirus infection was identified using reverse-transcription polymerase chain reaction. Multivariable logistic regression was used to compare exposures reported by participants with rotavirus infection with those of participants who tested negative. Multiple imputation was used to account for missing responses in the data set. The age-adjusted prevalence of asymptomatic rotavirus infection was 11%; prevalence was highest in children under age 18 years. Attendance at day care was a risk factor for asymptomatic rotavirus infection in children under age 5 years; living in a household with a baby that was still in diapers was a risk factor in older adults. The results suggest that asymptomatic rotavirus infection is transmitted through the same route as rotavirus infectious intestinal disease: person-to-person contact. More work is needed to understand the role of asymptomatic infections in transmission leading to rotavirus disease. PMID:20392863

    Venous malformations arising from the peripheral nerve are a rare type of vascular malformation. We present the first case of an intraneural venous malformation of the median nerve to be reported in a child and review the previous two cases of median nerve compression due to a venous malformation that have been reported. These cases presented with painless masses in the volar aspect of the wrist or with symptoms suggestive of carpal tunnel syndrome. Clinical suspicion should lead to the use of Doppler ultrasonography as the first-line diagnostic tool. Magnetic resonance imaging and histopathology can confirm the diagnosis, as phleboliths are pathognomonic of venous malformations. Surgical treatment appears to be the only modality capable of successfully controlling the growth of an intraneural malformation. Sclerotherapy and radiotherapy have never been used to treat this type of malformation.

    Full Text Available Implantable central venous port catheters are widely used in the management of children with cancer undergoing long term chemotherapy. These catheters can manifest a number of complications such as arrhythmia. Central venous port catheter was placed on a ten years old boy for chemotherapy. Before insertion of port catheter his physical examination, laboratory parameters, electrocardiography and echocardiography were normal. The patient felt palpitations shortly after the insertion of the port catheter. At that time the heart rate was 200 beats/minute but immediately normal sinus rhythm was restored. A chest roentgenogram revealed that the distal fragment of the port catheter was inside the right atrium. The port catheter was pulled back somewhat and then tachycardia attacks stopped. To our knowledge there are a few reports of supraventricular tachycardia (SVT in children associated with central venous port catheter. Here we aimed to present a pediatric case with SVT after placement of central venous port catheter and his management.

    Prescription of thromboprophylaxis is not a common practice in pediatric intensive care units. Most thrombi are catheter-related and asymptomatic, without causing acute complications. However, chronic complications of these (a)symptomatic catheter-related thrombi, that is, postthrombotic syndrome (PTS) and residual thrombosis have not been studied. To investigate these complications, critically ill children of 1 tertiary center with percutaneous inserted femoral central venous catheters (FCVCs) were prospectively followed. Symptomatic FCVC-thrombosis occurred in 10 of the 134 children (7.5%; 95% confidence interval [CI], 2.4-9.5). Only FCVC-infection appeared to be independently associated (P=0.001) with FCVC-thrombosis. At follow-up 2 of the 5 survivors diagnosed with symptomatic thrombosis developed mild PTS; one of them had an occluded vein on ultrasonography. A survivor without PTS had a partial occluded vein at follow-up. Asymptomatic FCVC-thrombosis occurred in 3 of the 42 children (7.1%; 95% CI, 0.0-16.7) screened by ultrasonography within 72 hours after catheter removal. At follow-up, mild PTS was present in 6 of the 33 (18.2%; 95% CI, 6.1-30.3) screened children. Partial and total vein occlusion was present in 1 (3%) and 4 (12%) children, respectively. In conclusion, children on pediatric intensive care units are at risk for (a)symptomatic FCVC-thrombosis, especially children with FCVC-infection. Chronic complications of FCVC-thrombosis are common. Therefore, thromboprophylaxis guidelines are warranted in pediatric intensive care units to minimize morbidity as a result of FCVC-thrombosis.

    Full Text Available Cerebral venous thrombosis (CVT has a wide spectrum of clinical manifestations that may mimic many other neurological disorders and lead to misdiagnoses. Headache is the most common symptom and may be associated with other symptoms or remain isolated. The other frequent manifestations are focal neurological deficits and diffuse encephalopathies with seizures. The key to the diagnosis is the imaging of the occluded vessel or of the intravascular thrombus, by a combination of magnetic resonance imaging (MRI and magnetic resonance venography (MRV. Causes and risk factors include medical, surgical and obstetrical causes of deep vein thrombosis, genetic and acquired prothrombotic disorders, cancer and hematological disorders, inflammatory systemic disorders, pregnancy and puerperium, infections and local causes such as tumors, arteriovenous malformations, trauma, central nervous system infections and local infections. The breakdown of causes differs in different parts of the world. A meta-analysis of the most recent prospectively collected series showed an overall 15% case-fatality or dependency rate. Heparin therapy is the standard therapy at the acute stage, followed by 3-6 months of oral anticoagulation. Patients with isolated intracranial hypertension may require a lumbar puncture to remove cerebrospinal fluid before starting heparin when they develop a papilloedema that may threaten the visual acuity or decompressive hemicraniectomy. Patients who develop seizures should receive antiepileptic drugs. Cerebral venous thrombosis - even pregnancy-related - should not contraindicate future pregnancies. The efficacy and safety of local thrombolysis and decompressive hemicraniectomy should be tested

    To study the effect of CO2 pneumoperitoneum and the special 30 degree head-down tilt positionon the venous hemodynamics in the lower extremity. Methods: Color doplex ultrasound was adopted to evaluate the diameterand blood flow velocity of the right femoral vein of 18 patients undergoing gynecologic laparoscopy under the same pressure ofpneumoperitoneum of 12 mmHg. The diameter of femoral vein and the flow velocity were measured; the blood flow volumewas calculated based on the equation of Q = vπr2 . Result: After establishment of pneumoperitoneum, the dilation of the fem-oral vein and the decrease in the velocity and volume can be observed (P < 0.05). And the 30 degree head-down positioncould increase the flow velocity and volume of the femoral vein and decrease the diameter of the vessel ( P < 0.05). At 30minutes of the 30 degree head-down tilt position, the blood flow ameliorated compared with that in prone position after theestablishment of pneumoperitoneum. After deflation of pneumoperitoneum, the femoral vein remained dilated( P < 0.05 ).Conclusion: During laparoscopy, CO2 pneumoperitoneum may result in the dilation of the vein in lower extremity and retar-dance of blood flow. The 30 degree Trendlenburg position can ameliorate the blood flow in the lower extremity. The deflationof the pneumoperitoneum cannot eliminate the effect of CO2 pneumoperitoneum on the lower extremity veins, which may pre-dispose deep venous thrombosis after laparoscopy.

    Chronic cerebrospinal venous insufficiency (CCSVI) is a syndrome characterized by stenosies of the internal jugular and/or azygous veins (IJVs-AZ) with opening of collaterals and insufficient drainage proved by reduced cerebral blood flow and increased mean transit time in cerebral MRI perfusional study. The present review is aimed to give a comprehensive overview of the actual status of the art of the diagnosis and treatment of this condition. As far as the origin of venous narrowing is concerned, phlebographic studies of the IJVs and AZ systems demonstrated that venous stenoses were likely to be truncular venous malformations; mostly, they are intraluminal defects such as malformed valve, septa webs. CCSVI condition has been found to be strongly associated with multiple sclerosis (MS), a disabling neurodegenerative and demyelinating disease considered autoimmune in nature. In several epidemiological observations performed at different latitudes on patients with different genetic backgrounds, the prevalence of CCSVI in MS ranges from 56% to 100%. To the contrary, by using venous MR and/or different Doppler protocols, CCSVI was not detected with the same prevalence. Two pilot studies demonstrated the safety and feasibility in Day Surgery of the endovascular treatment of CCSVI by means of balloon angioplasty (PTA). It determines a significant reduction of postoperative venous pressure. Restenosis rate was found out elevated in the IJVs, but negligible in the AZ. However, PTA seems to positively influence clinical and QoL parameters of the associated MS and warrants further randomized control trials.

However, the positive diagnostic value of this noninvasive test in clinically suspected pulmonary embolism is not very high (10%–18%. Since thromboembolic risks increase considerably in hospitalized patients with advanced age, this study aims to determine the importance of lower extremity venous color flow duplex scan in this particular subgroup of patients with clinically suspected pulmonary embolism. The effects of clinical presentation and risk factors on the results of duplex scan have been also studied. Methods: Between July 2007 and January 2010, 95 consecutive Lebanese geriatric ($60 years of age inpatients with clinically suspected pulmonary embolism assessed in an academic tertiary-care center for complete lower extremity venous color flow duplex scan were retrospectively reviewed. Age varied between 60 and 96 years (mean, 79.9 years. Forty patients were males and 55 females. Absence of compressibility was the most important criteria for detecting acute venous thrombosis. Results: Out of 95 patients, 33 patients (34.7% were diagnosed with recent deep venous thrombosis of lower extremities (14 proximal and 19 distal using complete venous ultrasound. Nine of these 33 patients (27.2% had a history of venous thromboembolism and eleven (33.3% presented with edema of lower

    By ultrasound scanning it was determined that respiratory movements made by chest of healthy and sick person are accompanied by respiratory chest rise of internal jugular veins. During the exhalation of an individual diameter of his veins increases and during the breath it decreases down to the complete disappearing if their lumen. Change of the diameter of internal jugular veins in different phases can influence significantly the results of vein puncture and cauterization in patients. The purpose of this research is development of the method increasing the efficiency and safety of cannulation of internal jugular veins by the ultrasound visualization. We suggested the method of catheterization of internal jugular veins by the ultrasound navigation during the execution of which the puncture of venous wall by puncture needle and the following conduction of J-guide is carried out at the moment of patient’s exhalation. This method decreases the risk of complications development during catheterization of internal jugular vein due to exclusion of perforating wound of vein and subjacent tissues and anatomical structures.

  11. New anticoagulants for the treatment of venous thromboembolism

    Full Text Available Worldwide, venous thromboembolism (VTE is among the leading causes of death from cardiovascular disease, surpassed only by acute myocardial infarction and stroke. The spectrum of VTE presentations ranges, by degree of severity, from deep vein thrombosis to acute pulmonary thromboembolism. Treatment is based on full anticoagulation of the patients. For many decades, it has been known that anticoagulation directly affects the mortality associated with VTE. Until the beginning of this century, anticoagulant therapy was based on the use of unfractionated or low-molecular-weight heparin and vitamin K antagonists, warfarin in particular. Over the past decades, new classes of anticoagulants have been developed, such as factor Xa inhibitors and direct thrombin inhibitors, which significantly changed the therapeutic arsenal against VTE, due to their efficacy and safety when compared with the conventional treatment. The focus of this review was on evaluating the role of these new anticoagulants in this clinical context.

    The initial element in the causation of venous ulceration is a disturbance of venous blood flow that leads to an increase in venous pressure. Eventually, however, it is the microcirculatory consequences of venous hypertension that lead to trophic skin changes and finally to ulceration. A reduction in blood viscosity results in an improvement at the microcirculatory level. The elimination of fibrinogen from plasma improves blood viscosity. This case report concerns a 75-year-old woman with venous ulcers of both legs (left lower leg: deep ulceration with a surface area of 3 x 5 cm; right lower leg: superficial, confluent ulceration with a total surface area of 5 x 10 cm). The patient underwent 20 sessions of fibrinogen adsorption, while simultaneously continuing with a regimen of conservative measures (activated charcoal cloth dressing with silver, calcium alginate dressings and short-stretch compression bandages). Following binding to a peptide (Gly-Pro-Arg-Pro-Lys), fibrinogen and fibrin were specifically removed from the patient's plasma: her fibrinogen concentration was lowered from an original mean level of 310 mg/dl (SD +/- 104 mg/dl) to 136 mg/dl (SD +/- 54 mg/dl), and there was no return to the baseline concentration by the time of the next fibrinogen adsorption session. In response to this treatment the patient's ulcers healed rapidly within 9 weeks. Dizziness and hematomas at the vascular access sites in both antecubital fossae were reported as adverse effects. A fall in hematocrit was also noted (before treatment 37% +/- 1%; after treatment 35% +/- 2%). This may have been caused by hemodilution due to the procedure and to cell losses during blood-plasma separation, a phenomenon that is known to occur during apheresis. This case report suggests that fibrinogen adsorption is low in adverse effects and is a useful addition to the range of treatments available for ulcers of venous etiology. PMID:14524041

    Noroviruses (NoV) are the most common cause of epidemic gastroenteritis world-wide. NoV infections are often asymptomatic, although individuals still shed large amounts of NoV in their stool. Understanding the differences between asymptomatic and symptomatic individuals would help in elucidating mechanisms of NoV pathogenesis. Our goal was to compare the serum cytokine responses and faecal viral RNA titres of asymptomatic and symptomatic NoV-infected individuals. We tested serum samples from infected subjects (n = 26; 19 symptomatic, seven asymptomatic) from two human challenge studies of GI.1 NoV for 16 cytokines. Samples from prechallenge and days 1-4 post-challenge were tested for these cytokines. Cytokine levels were compared to stool NoV RNA titres quantified previously by reverse transcription-polymerase chain reaction (RT-qPCR). While both symptomatic and asymptomatic groups had similar patterns of cytokine responses, the symptomatic group generally exhibited a greater elevation of T helper type 1 (Th1) and Th2 cytokines and IL-8 post-challenge compared to the asymptomatic group (all P viral RNA titre was associated positively with daily IL-6 concentration and negatively with daily IL-12p40 concentration (all P viral RNA titre, duration of viral shedding or cumulative shedding. Symptomatic individuals, compared to asymptomatic, have greater immune system activation, as measured by serum cytokines, but they do not have greater viral burden, as measured by titre and shedding, suggesting that symptoms may be immune-mediated in NoV infection.

    Quality of life (QOL) can be defined as the functional effect of an illness and its consequent therapy upon a patient, as perceived by the patient. Studies on the impact of chronic venous disease on quality of life are scarce compared to quality of life research in other diseases. The purpose of this paper was to describe instruments that assess the quality of life in patients with chronic venous disease and to review the literature on this topic. A computer search of the MedLine database was performed to identify papers; the bibliographies of relevant articles were reviewed to obtain additional papers. Papers were included if they described the development or use of a quality of life instrument for patients with chronic venous disease. A total of 25 papers were identified that fit the inclusion criteria. The studies described in the papers used six different generic instruments and ten disease-specific instruments. Quality of life in chronic venous disease was assessed in 12 studies. Six studies compared different types of treatment for chronic venous disease where QOL was an outcome measure. Despite the wide variety of measures used, results indicate that the quality of life of patients with chronic venous disease is affected in the physical domain mostly with regard to pain, physical functioning and mobility, and that they suffer from negative emotional reactions and social isolation. We feel that QOL should be a standard measure in future studies in patients with chronic venous disease, preferably with a combination of generic and disease-specific measures. PMID:12876622

    A series of 12 patients with vasculogenic impotence (4 arterial lesions; 8 arterial and venous lesions) underwent deep dorsal vein arterialisation after pre-operative assessment by a multidisciplinary approach. Cumulative graft patency was 58% (7 of 12 patients) up to 21 months but only 4 patients developed almost normal erections. Digital angiography, with and without the intracavernous injection of papaverine, was performed during follow-up to determine the vascular physiological status. At flaccidity, the corpora cavernosa were never opacified in the absence of a venocorporeal shunt. The penile glans was always visualised. Opacification of the deep dorsal vein and the circumflex system decreased with penile rigidity, resulting from their compression between Buck's fascia and the tunica albuginea. Intracavernous pressure recorded before and after the surgical procedure showed a marked increase when a caverno-venous shunt was performed. Hypervascularisation of the glans occurred in 2 cases. The relevance of this new surgical technique and its functional mechanism are discussed.

    Objectives To detect the effects of P-selectin on deep venous thrombosis (DVT) in nephrotic syndrome (NS). and to evaluate the molecular magnetic resonance imaging (MRI) with a P-selectin targeted conlrost agent in diagnosis of thrombosis in the early phase. Methods (1) Forty-one patients with NS hospitalized in our department from 2005 to 2006 were enrolled in this study. They were assigned into DVT group and non-DVT group according to lower limbs radionuclide imaging (RNV) with 99mTc MAA. Blood P-selectin level was measured by ELISA method. (2) P-selectin was detected both in injured vein and blood immediately, 1 h and 3 h after the dog DVT model was established. (3) The P-selectin-targeted contrast agent was developed by conjugating anti-P-selectin lectin-EGF domain monoclonal antibody (PsL-EGFmAb) which was prepared by our lab. The potential of this contrast agent used in vitro molecular imaging experiment as well as in vivo experiment in dog DVT model was investigated. Results (1) Blood P-selectin level was elevated in patients with NS. It was much higher in DVT group than that in non-DVT group. (2) Blood P-selectin level was also elevated in DVT dogs and P-selectin expressed immediately in tunica intima of injured vein and subsequently in thrombus after the model established. (3) Mural thrombus showed higher signal visualization than surrounding muscle in 30 rain after contrast agent injection. These enhanced signals exhibited P-selectin specificity and persisted from the initiation of intima lesions to 3 h after development of thrombosis. There was signficant Differences in contrast-to-noise ratio (CNR) of the experiment group and the control group (11.50±2.32 vs 2.71±0.86, P<0.01). The same results were derived from 30 rain to 1 hafter contrast agent being injected in distal to heart part of the injured vessel, and the signal decreased 24 h later.

    clinical significance of coagulation function in patients with lower extremity deep venous thrombosis (LEDVT) after gynecological pelvic surgery. Methods; ACL - TOP automated coagulation analyzer was used to detect plasma prothrombin times (PT) , activated partial thromboplastin times (APTT) , plasma thrombin times (TT) , plasma fibrinogen (FIB) concentrations, and D - dimer levels in 30 patients with LEDVT after gynecological pelvic surgery (including 9 patients with cervical cancer, 6 patients with ovarian cancer, 8 patients with endometrial cancer, 5 patients with hysteromyoma, one patient with adenomyoma, and one patient with tubal pregnancy) and 58 patients without LEDVT (including 40 patients with gynecological malignant tumor and 18 patients withhysteromyoma) after gynecological pelvic surgery, then the results were compared with those of normal women (control group) after physical examination. Results: Before operation, FIB concentrations and D - dimer levels in the patients with LEDVT after gynecological pelvic surgery and the patients without LEDVT after gynecological pelvic surgery were statistically significantly higher than those in control group ( P 0.05) . After 24 hours, FIB concentration and D - dimer level in the patients with LEDVT after gynecological pelvic surgery were statistically significantly higher than those in the patients without LEDVT after gynecological pelvic surgery and control group (P 0.05) . After anticoagulant therapy, thrombolytic therapy, and anti - inflammatory therapy, all the patients were cured, no complications occurred. After recovery, there was no statistically significant difference in PT, APTT, TT, FIB, and D - dimer levels between the patients after gynecological pelvic surgery and control group (P > 0.05 ) . Conclusion: Coagulation function detection, especially FIB and D - dimer detection, has important effect for laboratory examination of patients with LEDVT after gynecological pelvic surgery, which can be used for early
