    The revised Dutch College of General Practitioners (Nederlands Huisartsen Genootschap [NHG]) guideline 'Deep-vein thrombosis and pulmonary embolus' includes recommendations for the treatment of patients with deep-vein thrombosis (DVT) and thrombophlebitis, and for the exclusion of pulmonary embolism (PE). The general practitioner (GP) can exclude the presence of DVT or PE in some patients by using a decision rule and a D-dimer test. When using D-dimer test as a point-of-care test, meticulous care is essential during the test procedure and storage of blood. The GP can treat many patients with DVT; the NHG guideline does not advise use of direct oral anticoagulants. In the case of an isolated DVT in the calf, treatment with anticoagulants or ultrasound follow-up can be chosen in consultation with the patient or on the basis of regional agreements. In the case of patients with superficial thrombophlebitis, a wait-and-see approach is usually sufficient.

    Pulmonary embolism is traditionally, since autopsy studies by Virchow in the mid 1800s, thought to originate from embolization of a deep-vein thrombosis, resulting in two clinical manifestations of one disease: venous thrombosis. The incidence of deep-vein thrombosis in the population is twice as hi

    After lung transplantation, pulmonary vein thrombosis is a rare, potentially life-threatening adverse event arising at the pulmonary venous anastomosis that typically occurs early and presents as graft failure and hemodynamic compromise with an associated mortality of up to 40%. The incidence, presentation, outcomes, and treatment of late pulmonary vein thrombosis remain poorly defined. Management options include anticoagulant agents for asymptomatic clots, and thrombolytic agents or surgical thrombectomy for hemodynamically significant clots. We present a rare case highlighting a delayed presentation of pulmonary vein thrombosis occurring longer than 2 weeks after lung transplantation and manifesting clinically as graft failure secondary to refractory pulmonary edema. The patient was treated successfully with surgical thrombectomy and remains well. We recommend a high index of suspicion of pulmonary vein thrombosis when graft failure after lung transplantation occurs and is not responsive to conventional therapy, and consideration of investigation with transesophageal echocardiography or computed tomography with venous phase contrast in such patients even more than 2 weeks after lung transplantation.

    The pulmonary embolism (PE) is the common and severe complication of the deep vein thrombosis of the lower limbs. The lack of accurate diagnosis of PE is a cause of 5-10% of the hospital deaths. The aim of the study was to assess the incidence of the pulmonary embolism in patients with the deep vein thrombosis of the lower limbs with no clinical symptoms of pulmonary embolism. Pulmonary perfusion scintigraphy was performed in 25 patients with angiographic findings confirmative to the deep vein thrombosis of the lower limbs. The results of the study were analysed according to the PIOPED criteria. In the group of patients with common thrombosis of the deep vein a high probability of lung embolism was assessed in 70%, medium and low by 12% in each group, and very low in 6%. In the group of patients with femoral thrombosis of the deep vein a high probability of lung embolism was assessed in 60%, medium in 20% and very low in 20%. In the group of patients with calf thrombosis of the deep vein high, medium and very low probability of lung embolism was assessed by 25% in each group. Results of this study indicate the need of searching the pulmonary embolism in patients with thrombosis of the deep vein of the lower limbs despite the lack of clinical symptoms of the pulmonary embolism.

    A young 23-year-old male patient presented with a two-day history of right flank pain. He had no history of any significant illnesses in the past. His investigations showed nephrotic range proteinuria with hypoalbuminemia. The patient developed cough and shortness of breath after having a left kidney biopsy. He did not respond to regular respiratory tract infection treatment. The kidney biopsy revealed membranoproliferative glomerulonephritis. Further investigations for the cough showed thromboembolism of the posterior and lateral basal segments of the right lower lobe. Moreover he was found to have thrombosis of the right upper pole renal vein. The patient was started on full anticoagulation along with three days pulse steroid, followed by 1 mg/kg oral steroid. Clinical improvement was noticed within 48 h. After eight weeks the proteinuria decreased from 8.5 gm/day to 1.1 gm/day. The kidney function was normal with eGFR 145 mL/min through the course of the disease. This case represent one of the unusual presentation of nephrotic syndrome with pulmonary and renal vascular thromboembolic events. The response to the combination of anticoagulation and steroid was remarkable.

    A 43-year-old male experienced renal infarction (RI) following left upper lobectomy for lung cancer. The patient complained of acute-onset severe left flank pain on the 14th postoperative day. A contrast-enhanced computed tomography (CT) of the abdomen revealed RI by a large wedge-shaped defect in the left kidney. A chest CT scan located the thrombus in the stump (a blind-ended vessel) of the left superior pulmonary vein. Therefore, thromboembolic RI caused by pulmonary vein thrombosis was suspected. Anticoagulation therapy was initiated with heparin and warfarin to treat RI and to prevent further embolic episodes. Two months later, pulmonary vein thrombosis had resolved without the appearance of additional peripheral infarction. This case emphasizes the need to consider thrombus in the stump of the pulmonary vein as a cause of RI.

    Pulmonary venous thromboembolism has only been identified as a cause of stroke with pulmonary arteriovenous malformations\\/fistulae, pulmonary neoplasia, transplantation or lobectomy, and following percutaneous radiofrequency ablation of pulmonary vein ostia in patients with atrial fibrillation. A 59-year-old man presented with a posterior circulation ischemic stroke. \\'Unheralded\\' pulmonary vein thrombosis was identified on transesophageal echocardiography as the likely etiology. He had no further cerebrovascular events after intensifying antithrombotic therapy. Twenty-eight months after initial presentation, he was diagnosed with metastatic pancreatic adenocarcinoma and died 3 months later. This report illustrates the importance of doing transesophageal echocardiography in presumed \\'cardioembolic\\' stroke, and that potential \\'pulmonary venous thromboembolic\\' stroke may occur in patients without traditional risk factors for venous thromboembolism. Consideration should be given to screening such patients for occult malignancy.

    Full Text Available The chylothorax is not a common presentation, and bilateral chylothorax in patients with chronically high central venous pressure secondary to venous thrombosis is a rare in incidence. We reported a case of bilateral chylothorax in a patient of chronic deep vein thrombosis (DVT in central veins with chronic thromboembolic pulmonary hypertension who presented with 2 weeks history of increased breathlessness, bilateral chest discomfort and weakness. Work-up with chest X-ray and ultrasonography-chest showed gross left sided and mild right sided pleural effusion, thoracocentesis was consistent with chylothorax. Contrast enhanced computed tomography-chest showed multiple collateral formation of left side subclavian vein, venous Doppler showed old DVT in right and left subclavian veins and two-dimensional echocardiogram showed finding of severe pulmonary hypertension. After 24 h of fasting and conservative management, pleural drain became clear and decreased in the amount. Patient′s video assisted thoracoscopic surgery was done, and thoracic duct was ligated and cut down at diaphragmatic level and bilateral talc pleurodesis done. Patient improved clinically and radiologically.

    Full Text Available Abstract Popliteal artery aneurysms representing 80% of peripheral artery aneurysms rarely rupture (a reported incidence of 0.1–2.8 % and second commonest in frequency after aorto-iliac aneurysms. They usually present with pain, swelling, occlusion or distal embolisation and can cause diagnostic difficulties. We report a 78 year old man who was previously admitted to hospital with a pulmonary embolus secondary to deep venous thrombosis. He was heparinized then warfarinised and was readmitted with a ruptured popliteal aneurysm leading to a large pseudo aneurysm formation. The pulmonary embolus had been due to popliteal vein thrombosis and propagation of the clot. A thorough review of literature identified only one previously reported case of ruptured popliteal artery aneurysm and subsequent large pseudo aneurysm formation. We feel it is important to exclude a popliteal aneurysm in a patient with DVT. This may be more common than the published literature suggests.

    Renal vein thrombosis in adults is usually a complication of the nephrotic syndrome. Rarely, it has been reported in nonnephrotic women postpartum. The thrombosis may be a complication of the hypercoagulable state associated with both the nephrotic syndrome and pregnancy. Two postpartum patients with renal vein thrombosis and no prior history of renal disease are reported here. Neither patient had heavy proteinuria. In both cases, pyelonephritis was suspected clinically and the diagnosis of renal vein thrombosis was first suggested and confirmed by radiologic examination. Renal vein thrombosis should be considered in women presenting postpartum with flank pain.

    Full Text Available Total anomalous pulmonary venous return (TAPVR is a rare and frequently isolated defect identified in 1% to 3% of all congenital heart diseases. To the best of our knowledge, portal vein thrombosis (PVT associated with TAPVR has not been reported in the literature. We report a successfully managed PVT in a newborn with infracardiac-type TAPVR and review the literature. Anticoagulation therapies were used during the neonatal period to prevent thrombus progression. PVT should be kept in mind in TAPVR patients who have open heart repair with total correction. The treatment in each neonate should be individualized with consideration of the risk/benefit ratio.

    Full Text Available Portal vein thrombosis (PVT is the blockage or narrowing of the portal vein by a thrombus. It is relatively rare and has been linked with the presence of an underlying liver disease or prothrombotic disorders. We present a case of a young male who presented with vague abdominal symptoms for approximately one week. Imaging revealed the presence of multiple nonocclusive thrombi involving the right portal vein, the splenic vein, and the left renal vein, as well as complete occlusion of the left portal vein and the superior mesenteric vein. We discuss pathogenesis, clinical presentation, and management of both acute and chronic thrombosis. The presence of PVT should be considered as a clue for prothrombotic disorders, liver disease, and other local and general factors that must be carefully investigated. It is hoped that this case report will help increase awareness of the complexity associated with portal vein thrombosis among the medical community.

    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.

    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.

    Superior mesenteric vein thrombosis was identified on computed tomographic scans in six patients. In each case, contrast-enhanced scans showed a high-density superior mesenteric vein wall surrounding a central filling defect. Four fo the six patients had isolated superior mesenteric vein thrombosis. A fifth patient had associated portal vein and splenic vein thrombosis, and the sixth patient had associated portal vein and inferior vena cava thrombosis. One of the six patients had acute ischemic bowel disease. The other five patients did not have acute ischemic bowel symptoms associated with their venous occlusion. This study defines the computed tomographic appearance of mesenteric vein thrombosis.

Case presentation A 42 year old man was found to have a paradoxical embolism in the systemic arterial circulation, in the setting of pulmonary embolism and deep vein thrombosis (DVT in the lower extremities. Conclusion Paradoxical embolism and intracardiac shunt should be immediately considered in a patient with pulmonary embolism and systemic arterial embolism. Diagnostic modalities included arteriogram and saline contrast echocardiography. Closure of intracardiac shunt is needed for patients who are at risk for recurrent embolic events.

    Venous thromboembolism (VTE), a disease entity comprising deep vein thrombosis (DVT) and pulmonary embolism (PE), is a frequent and potentially life-threatening event. To date different agents are available for the effective treatment of acute VTE and the prevention of recurrence. For several years, the standard of care was the subcutaneous application of a low molecular weight heparin (LMWH) or fondaparinux, followed by a vitamin K antagonist (VKA). The so-called direct oral anticoagulants (DOAC) were introduced rather recently in clinical practice for the treatment of VTE. DOAC seem to have a favorable risk-benefit profile compared to VKA. Moreover, DOAC significantly simplify VTE treatment because they are administered in fixed doses and no routine monitoring is needed. Patients with objectively diagnosed DVT or PE should receive therapeutic anticoagulation for a minimum of 3 months. Whether a patient ought to receive extended treatment needs to be evaluated on an individual basis, depending mainly on risk factors determined by characteristics of the thrombotic event and patient-related factors. In specific patient groups (e.g., pregnant women, cancer patients, and elderly patients), treatment of VTE is more challenging than that in the general population and additional issues need to be considered in those patients. The aim of this review is to give an overview of the currently available treatment modalities of acute VTE and secondary prophylaxis. In particular, specific aspects regarding the initiation of VTE treatment, duration of anticoagulation, and specific patient groups will be discussed. PMID:26664901

    2015-09-01

    Full Text Available Background: Obesity is a growing problem all over the world, including the United States. Single-incision laparoscopic sleeve gastrectomy is a surgery performed for patients who want to lose weight. The number of deaths resulting from thromboembolic complications from bariatric surgeries continues to be of major concern. Case Description: A 38-year-old female was admitted for single incision sleeve gastrectomy and was discharged home three days later. Subsequently she began to have abdominal pain, nausea and vomiting. A CT scan revealed superior mesenteric vein thrombosis with small bowel ischemia, splenic infarction and main and right portal vein branch thrombosis. An exploratory laparotomy demonstrated necrotic bowel due to abdominal compartment syndrome, and an area of small bowel was resected due to internal hernia. Surgical management of the patient during her second hospital stay included a decompressive laparotomy, internal hernia reduction, a small bowel resection. Discussion: Superior mesenteric vein thrombosis can be a life-threatening complication and present with non-specific presentations; thus, it is imperative that it is identified and managed promptly as these cases carry significant morbidity and mortality. Obese patients who undergo bariatric surgery frequently have other co-morbidities; many of which can complicate a case further. Mesenteric vein thromboses are normally treated with unfractionated or low-molecular-weight heparin.

    Abstract Previous studies indicated that gout is a risk factor of cardiovascular diseases. This study aimed to determine if patients with gout have an increased risk of deep vein thrombosis (DVT) or pulmonary embolism (PE). We used the Longitudinal Health Insurance Database, a subset of the national insurance claim dataset, which enrolled 1 million Taiwanese to identify 57,981 patients with gout and 115,961 reference subjects matched by sex, age, and entry date of diagnosis. The risk of DVT and PE was analyzed using the Cox proportional hazards model. In this Taiwanese dataset observed from 2000 to 2010, we found the incidence of DVT was 5.26 per 104 person-years in the gout cohort, which was twofold higher than the incidence of 2.63 per 104 person-years in the reference cohort. After adjusting for age, sex, and 9 comorbidities, the hazard ratio (HR) of developing DVT was 1.66 (95% confidence interval [CI] = 1.37–2.01). Among patients with gout, the youngest age group had the highest increase in the risk of developing DVT (HR [95% CI] = 2.04 [1.24–3.37] for ages 20 to 49 years, 1.80 [1.28–2.51] for ages 50 to 64 years, and 1.45 [1.11–1.91] for ages ≥65 years). The incidence of PE was about one-fifth that of DVT in gout patients, but the effect of gout on the risk was similar (HR [95% CI] = 1.53 [1.01–2.29]). Our analysis confirmed that gout increased the risk of DVT and PE. Further exploration is needed in the future. PMID:26705202

    Renal vein thrombosis is a rare entity in which true incidence is unknown. The disease occurs most frequently in patients with nephrotic syndrome, but it also can occur in the presence of other hypercoagulable state. Two cases of renal vein thrombosis with nephrotic syndrome which were treated by thrombectomy are reported here. One patient was successfully treated by renal vein and inferior vena cava thrombectomy before developing severe pulmonary embolism. The other was treated by renal vein thrombectomy by which fatal shock was able to be prevented. In those cases, immediate operation was indicated, primarily to prevent additional, possibly fatal, pulmonary embolism and also to improve perfusion of the kidney. In the hope of salvaging the kidney, thrombectomy may be the treatment of choice for acute renal vein thrombosis, complication of pulmonary embolism and inferior vena cava thrombosis, right renal vein thrombosis without collateral flow and acute renal vein thrombosis with shock.

    We studied 21 cases of pulmonary thromboembolism (PTE) in 67 consecutive cases of deep vein thrombosis (DVT) of the lower limbs and 4 cases in 9 selective cases of rheumatic heart disease (RHD). The incidence of PTE in DVT could be inferred as being 31.3%. PTE were diagnosed by 99mTc MAA lung scintiscans. In the DVT cases, lung scintiscan were done right after venography of the legs. Six cases underwent pulmonary angiography, ⅠDSA. As PTE in the DVT cases were all subclinical, only oligemia andvascular "pruning" were noted. Injection of urokinase into the pulmonary artery concerned through a catheter after which intravenous infusion was continued for 10-14 days, only 3 PTE resolved, probably representing early cases.

    Full Text Available Intracardiac thrombus, pulmonary artery aneurysms, deep vein thrombosis, and pulmonary thromboembolism are rarely seen symptoms of Behcet’s disease. A 20-year-old female patient was admitted for complaints of cough, fever, palpitations, and chest pain. On the dynamic thorax computed tomograms (CT obtained because of significantly enlarged hilar structures seen on chest radiograms, aneurysmal dilatation of the pulmonary artery segments bilaterally, chronic thrombus with collapse, and consolidation substances compatible with pulmonary embolism involving both lower lobes have been observed. It is learned that, four years ago, the patient had been diagnosed with Behcet’s disease and received colchicine treatment but not regularly. The patient was hospitalized. On the transthoracic echocardiogram, a thrombosis with a dimension of 4.2 × 1.6 cm was recognized in the right ventricle. On abdomen CT, aneurysmal iliac veins and deep vein thrombus on Doppler ultrasonograms were diagnosed. At the controls after three months of immunosuppressive and anticoagulant therapies, some clinical and radiological improvements were recognized. The patient suspended the treatment for a month and the thrombus recurred. We present our case in order to show the effectiveness of immunosuppressive and anticoagulant therapies and rarely seen pulmonary thromboembolism in recurrent Behcet’s disease.

    Neonatal renal vein thrombosis (RVT) continues to pose significant challenges for pediatric hematologists and nephrologists. The precise mechanism for the onset and propagation of renal thrombosis within the neonatal population is unclear, but there is suggestion that acquired and/or inherited thrombophilia traits may increase the risk for renal thromboembolic disease during the newborn period. This review summarizes the most recent studies of neonatal RVT, examining its most common features, the prevalence of acquired and inherited prothrombotic risk factors among these patients, and evaluates their short and long term renal and thrombotic outcomes as they may relate to these risk factors. Although there is some consensus regarding the management of neonatal RVT, the most recent antithrombotic therapy guidelines for the management of childhood thrombosis do not provide a risk-based algorithm for the acute management of RVT among newborns with hereditary prothrombotic disorders. Whereas neonatal RVT is not a condition associated with a high mortality rate, it is associated with significant morbidity due to renal impairment. Recent evidence to evaluate the effects of heparin-based anticoagulation and thrombolytic therapy on the long term renal function of these patients has yielded conflicting results. Long term cohort studies and randomized trials may be helpful to clarify the impact of acute versus prolonged antithrombotic therapy for reducing the morbidity that is associated with neonatal RVT.

    Factor V Leiden (FVL) is by far the most prevalent inherited thrombophilic abnormality in Western countries, and this genetic condition has been associated with sudden sensorineural hearing loss (SSHL). Audiologists should be aware that SSHL may be the precursor of life-threatening thromboembolic events, especially in Caucasians who are more likely to be FVL carriers. Case report. A 41-year-old male patient. Although this is not the first report of SSHL in a FVL carrier, it is the first to describe SSHL occurring in a heterozygous FVL carrier who--within a month--was also diagnosed with deep vein thrombosis of the left common femoral, saphenous, and popliteal veins, and pulmonary embolism of the left pulmonary artery branch serving the posterior basal segment of the inferior lobe. SSHL is an emergency condition that warrants prompt medical examination and treatment. Hematological investigations should be considered in SSHL patients at least for those with a family history of thrombotic events, and for women on estrogen-progestin therapy or during pregnancy, with a view to providing adequate antithrombotic prophylaxis and reducing the risk of other thromboembolic events.

  19. A patient who experienced thyroid storm complicated by rhabdomyolysis, deep vein thrombosis, and a silent pulmonary embolism: a case report

    2013-01-01

    Background Thyroid storm is a serious condition of thyrotoxicosis. Hyperthyroidism often presents with thrombotic events, especially at cerebral sites; however, the possible association between a lower extremity deep vein thrombosis (LEDVT) and thyroid storm has not been previously reported. We encountered a patient who developed thyroid storm, associated with rhabdomyolysis, followed by LEDVT and a small silent pulmonary embolism (PE). The case is discussed with references to the pertinent literature. Case presentation A 50-year-old woman with no past medical history was referred to our hospital because of severe diarrhea, muscle weakness in her lower limbs (manual muscle testing: MMT 3), and disturbances of consciousness. She was diagnosed as having Graves’ disease based on the presence of struma, exophthalmos, and hyperthyroidism with TSH receptor antibody positivity; we further determined that the patient was experiencing thyroid storm based on the results of the Burch-Wartofsky scoring system and a Japanese diagnostic criteria. Treatment with steroids, iodine potassium, methimazole, and propranolol was initiated. Severe watery diarrhea continued, and the laboratory data revealed hypokalemia (2.0 meq/L). On day 14, a blood analysis showed a sudden elevation in her creatinine kinase (CK) level, leading to a diagnosis of rhabdomyolysis. Thereafter, the muscle weakness in her lower limbs advanced to a degree of MMT 1. Seven days after the diagnosis of rhabdomyolysis, pitting edema began to appear in bilateral lower extremities. Contrast-enhanced CT scans revealed a LEDVT involving the left common iliac vein, bilateral femoral veins, and left popliteal vein. Furthermore, a small PE was identified. Hyperthyroidism often presents with thrombotic events, especially at cerebral sites, but few reports of PE or LEDVT have been made. Conclusion This case suggests that the occurrence of thyroid storm may be associated with a risk of LEDVT and/or PE. We suggest that DVT

    In this article, we present a rare case of calcified deep vein thrombosis in a 42-year-old female patient with frequent relapses of pulmonary sarcoidosis since 1995, for which she was on maintenance therapy with corticosteroids and with consequential secondary diabetes. Recent femoral vein thrombosis was diagnosed with color Doppler in 2012. At the same time, calcified occlusive thrombus in vena cava inferior from the level of renal vein to the confluence of hepatic veins was diagnosed on abdominal multi-slice computed tomography (MSCT). Digital subtraction venography (DSV) revealed a well-developed collateral circulation through the paravertebral veins, azygos and hemiazygos vein. There were no risk factors for thrombosis other than sarcoidosis and diabetes. Deep vein thrombosis is rarely described with sarcoidosis, but according to literature reports, it usually appears as a recurrence and simultaneously at multiple locations. According to the current knowledge, we cannot say for sure whether it is a disease with an increased risk of deep vein thrombosis or there is a combination of multiple risk factors present simultaneously.

    This article provides a review of the incidence, pathophysiology, and treatment of deep vein thrombosis (DVT) in pregnancy, a rare but serious complication of pregnancy. The incidence of DVT in pregnancy varies widely, but it is a leading cause of maternal morbidity in both the United States and the United Kingdom. Risk factors during pregnancy include prolonged bed rest or immobility, pelvic or leg trauma, and obesity. Additional risk factors are preeclampsia, Cesarean section, instrument-assisted delivery, hemorrhage, multiparity, varicose veins, a previous history of a thromboembolic event, and hereditary or acquired thrombophilias such as Factor V Leiden. Heparin is the anticoagulant of choice to treat active thromboembolic disease or to administer for thromboprophylaxis, but low molecular-weight heparin is being used with increasing frequency in the pregnant woman. Perinatal nurses should be aware of the symptoms, diagnostic tools, and treatment options available to manage active thrombosis during pregnancy and in the intrapartum and postpartum periods.

    We describe a 35-year-old Chinese woman with Behçet disease complicated by recurrent gastrointestinal flares. During admission for acute lower abdominal pain, a computed tomographic scan of the abdomen showed thrombosis of the left ovarian vein. She was treated with increased immunosuppressant and oral anticoagulant. Although she was not compliant to oral anticoagulant with her international normalized ratio frequently subtherapeutic, her symptoms abated and the thrombosis resolved. There has been only 1 reported case of a patient with Behçet disease presenting with postpartum ovarian vein thrombosis and pulmonary embolism and no reported case of Behçet disease with ovarian vein thrombosis occurring outside pregnancy and the puerperium. Ovarian vein thrombosis is a rare cause of abdominal pain that should be considered in patients with Behçet disease.

    The term factor V Leiden (FVL) paradox is used to describe the different risk of deep vein thrombosis and pulmonary embolism that has been found in carriers of FVL. In a thrombophilic family-cohort, we estimated differences in absolute risks of deep vein thrombosis and pulmonary embolism for various thrombophilic defects. Of 2,054 relatives, 1,131 were female, 41 had pulmonary embolism and 126 deep vein thrombosis. Annual incidence for deep vein thrombosis in non-carriers of FVL was 0.19% (95%CI, 0.16–0.23), and 0.41% (95%CI, 0.28–0.58) in carriers; relative risk (RR) 2.1 (95%CI, 1.4–3.2). For pulmonary embolism these incidences were similar in carriers and non-carriers 0.07%, respectively; RR 1.0 (95% CI, 0.4–2.5). When co-inheritance of other thrombophilic defects was excluded the RR for deep vein thrombosis in FVL carriers was 7.0 (95%CI, 2.3–21.7) compared to non-carriers and 2.8 (95%CI, 0.5–14.4) for pulmonary embolism. For other thrombophilic defects no such effect was observed. Thus the FVL paradox was confirmed in our study. However, a similar paradox in carriers of other thrombophilic defects was not observed.

    We present the sonographic findings of fetal renal vein thrombosis in a series of 6 patients. The mean gestational age at diagnosis was 31.2 weeks. Four cases were unilateral, and 2 were bilateral. The most common findings were renal enlargement and intrarenal vascular calcifications, followed by increased renal parenchymal echogenicity. Inferior vena cava thrombosis was found in 4 patients and common iliac vein thrombosis in 2. Fetal renal vein thrombosis is an uncommon diagnosis with characteristic sonographic findings. The presence of these findings should prompt Doppler interrogation of the renal vein and inferior vena cava to confirm the diagnosis.

It commonly affects the deep leg veins (such as the calf veins, femoral vein, or popliteal vein or the deep veins of the pelvis. It is a potentially dangerous condition that can lead to preventable morbidity and mortality.Aim: To present an update on the causes and management of DVT.Methods: A review of publications obtained from Medline search, medical libraries, and Google.Results: DVT affects 0.1% of persons per year. It is predominantly a disease of the elderly and has a slight male preponderance. The approach to making a diagnosis currently involves an algorithm combining pretest probability, D-dimer testing, and compression ultrasonography. This will guide further investigations if necessary. Prophylaxis is both mechanical and pharmacological. The goals of treatment are to prevent extension of thrombi, pulmonary embolism, recurrence of thrombi, and the development of complications such as pulmonary hypertension and post-thrombotic syndrome.Conclusion: DVT is a potentially dangerous condition with a myriad of risk factors. Prophylaxis is very important and can be mechanical and pharmacological. The mainstay of treatment is anticoagulant therapy. Low-molecular-weight heparin, unfractionated heparin, and vitamin K antagonists have been the treatment of choice. Currently anticoagulants specifically targeting components of the common pathway have been recommended for prophylaxis. These include fondaparinux, a selective indirect factor Xa inhibitor and the new oral selective direct thrombin inhibitors (dabigatran and selective

  9. PORTAL VEIN THROMBOSIS-ULTRASOUND IMAGING

    Full Text Available Portal venous system, apart from the main portal vein, includes its tributaries: superior and inferior mesenteric vein, as well as splenic vein, so the term portal venous thrombosis encompasses a broad spectrum of pathological conditions. Usually, one or more causative factors can be recognized, either local endothelial/ flow disturbances, or systemic inherited /acquired conditions. Portal vein thrombosis can be associated with benign or malignant disorders. Weather we are speaking about acute or chronic thrombosis, the clinical presentation is different. Acute thrombosis can be presented in a wide range, from mild abdominal discomfort to a state of intestinal ischemia and life-threatening infarction. Chronic thrombosis is usually recognized when variceal bleeding or other symptoms of portal hypertension express. Fast and accurate diagnosis sometimes is a life-saving procedure, especially in acute vascular alterations. Recently, due to the improvement of imaging procedures the number of patients with diagnosed portal vein thrombosis is increasingly growing. With a negative predictive value of 98% color Doppler ultrasound is considered as imaging modality of choice in detecting portal vein thrombosis. Based on large studies it is presumed that overall risk of getting portal vein thrombosis during lifetime is 1% in general population, but much bigger 5%-15% in cirrhotic patients. Existence of specific ultrasound criteria, if fulfilled, has ensured that diagnosis of portal vein thrombosis is fast and non-invasive. Procedure is convenient for the patient and healthcare providers, and above all, allows prompt treatment preventing further deterioration.

    To investigate which factors other than history of superficial vein thrombosis (SVT) are associated with recurrent spontaneous SVT episodes in patients with varicose veins (VVs). Patients with a history of spontaneous SVT and VVs were followed up for a mean period of 55 months. Demographics, comorbidities, and thrombophilia screening test were analyzed. Patients were grouped according to the clinical-etiology-anatomy-pathophysiology classification. A multiple logistic regression analysis with the forward likelihood ratio method was undertaken. Thirteen patients out of 97 had a recurrence SVT episode during the follow-up period. All those patients were identified to have a thrombophilia defect. Protein C and S, antithrombin, and plasminogen deficiencies were more frequently present in patients without recurrence. Gene mutations were present in 38% in the nonrecurrence group and 77% in the recurrence group. After logistic regression analysis, patients with dislipidemia and mutation in prothrombin G20210A (FII) had an increased risk for recurrence by 5.4-fold and 4.6-fold, respectively. No deep vein thrombosis or pulmonary embolism occurred. Dislipidemia and gene mutations of F II are associated with SVT recurrence in patients with VVs. A selection of patients may benefit from anticoagulation in the short term and from VVs intervention in the long term. © The Author(s) 2015.

    Full Text Available Internal jugular vein thrombosis (IJVT is a rare condition which may lead to life-threatening complications such as sepsis and pulmonary embolism. Prolonged central venous catheterization, intravenous (IV drug use, trauma, and radiotherapy are the most frequent causes of the IJVT. IJVT that develops after the oropharyngeal infection is a quite rare situation today. In this paper, a 37-year-old woman was presented; swelling occurred on her neck after acute tonsillitis and she was diagnosed with IJVT through Doppler ultrasonography and magnetic resonance imaging and managed without complications. Early diagnosis and conservative treatment with broad-spectrum IV antibiotics and anticoagulant agents have a critical importance for the prevention of fatal complications.

    The Vitamins and Thrombosis (VITRO) study investigated the effect of homocysteine lowering by daily supplementation of B vitamins on the risk reduction of deep vein thrombosis (DVT) and pulmonary embolism (PE). Patients between 20 to 80 years old with a first objectively confirmed proximal DVT or PE in the absence of major risk factors and a homocysteine concentration above the 75th percentile of a reference group were asked to participate (hyperhomocysteinemic group). A similar study was conducted in a random sample of patients with a homocysteine below the 75th percentile of the reference group (normohomocysteinemic group). After informed consent was obtained, patients were randomized to daily multivitamin supplementation (5 mg folic acid, 50 mg pyridoxine, and 0.4 mg cyanocobalamin) or placebo and were followed for 2.5 years. End points were objectively diagnosed recurrent DVT or PE. A total of 701 patients were enrolled (360 in the hyperhomocysteinemic and 341 in the normohomocysteinemic group). The number of recurrent events of venous thrombosis was 43 of 353 in the vitamin group (54/1000 py) and 50 of 348 in the placebo group (64/1000 py). The hazard ratio associated with vitamin treatment was 0.84 (95% CI, 0.56-1.26): 1.14 (95% CI, 0.65-1.98) in the hyperhomocysteinemic group and 0.58 (95% CI, 0.31-1.07) in the normohomocysteinemic group. The results of our study do not show that homocysteine lowering by B vitamin supplementation prevents recurrent venous thrombosis.

    Parathyroid carcinoma is a rare etiology of primary hyperparathyroidism responsible for 0.4 to 5.2% of all primary hyperparathyroidism cases. The overt hyperparathyroid bone or renal disease with palpable neck mass, as well as severe hypercalcemia with extremely high parathyroid hormone, are clinical parameters raising the suspicionforparathyroid carcinoma. However a definite diagnosis can be confirmed only by examining the histopathology of the tumor. The curative treatment solely depends on an en bloc surgical approach. Therefore, preoperative clinical diagnosis of carcinoma is essentialfor optimal surgical planning. Thepresent study reported asymptomatic subclavian vein thrombosis andpulmonary embolism in parathyroid carcinoma, suggesting paraneoplastic syndrome of hypercoagulability in this cancer type. The presence of this paraneoplastic syndrome in a case of overt clinical hyperparathyroidism in addition to a palpable neck mass indicated the diagnosis of carcinoma preoperatively in the present patient, which led to an en bloc surgical plan. Since this paraneoplastic syndrome can be asymptomatic, the exploration ofthis syndrome by a commonly used imaging technique for parathyroid tumor localization, computerized tomography, would enable a preoperative diagnosis of cancer especially in an equivocal situation.

    AIM: To estimate the prevalence of inherited and acquired thrombophilic risk factors in patients with abdominal venous thrombosis and to compare the risk factor profiles between Budd-Chiari syndromes (BCS) and splanchnic vein thrombosis (SVT).METHODS: In this retrospective study, 36 patients with abdominal venous thrombosis were studied.The patients were divided into Budd-Chiari group (hepatic vein, IVC thrombosis) and splanchnic venous thrombosis group (portal, splenic, superior mesenteric veins) based on the veins involved. Hereditary and acquired thrombophilic risk factors were evaluated in all patients.RESULTS: Twenty patients had SVT, 14 had BCS,and 2 had mixed venous thrombosis. Ten patients (28%) had hereditary and 10 patients (28%) acquired thrombophilic risk factors. The acquired risk factors were significantly more common in the SVT group (SVT vs BCS:45% vs 7%,x2=5.7,P=0.02) while hereditary risk factors did not show significant differences between the two groups (SVT vs BCS: 25%vs 36%, x2=0.46,P=0.7). Multiple risk factors were present in one (7%) patient with BCS and in 3 patients (15%) with SVT. No risk factors were identified in 57% of patients with BCS and in 45% of patients with SVT.CONCLUSION: Hereditary and acquired risk factors play an important role in the etiopathogenesis of abdominal venous thrombosis. Acquired risk factors are significantly more common in SVT patients while hereditary factors are similar in both groups.

    To review the literature on portal vein thrombosis in children and adolescents, focusing on its diagnosis, complications and treatment. The medical literature of the past 10 years was reviewed using the PubMed and MEDLINE search engines, with major focus on portal vein thrombosis and its clinical outcomes. The following keywords or expressions were used for the web search: portal vein thrombosis, extra-hepatic portal vein obstruction, prognosis, children, portal hypertension, esophagogastric varices. Additionally, we also reviewed the articles cited in the references of the initially selected papers, as well as relevant textbooks. Portal vein thrombosis is one of the most common causes of portal hypertension among children. The initial clinical manifestation is characterized either by episodes of upper gastrointestinal bleeding or by splenomegaly on routine clinical examination. The major complications include upper gastrointestinal bleeding, hypersplenism secondary to splenomegaly, growth retardation, and portal biliopathy. The diagnosis is made by abdominal Doppler ultrasonography. Treatment is targeted at the complications and includes primary and secondary prophylaxis against upper gastrointestinal bleeding (which results from the rupture of esophageal varices), and portosystemic shunting in selected cases. Portal vein thrombosis is one of the major triggers of upper gastrointestinal bleeding in children. Bleeding episodes have a remarkable effect on the quality of life of affected patients. Thus, appropriate diagnosis and treatment are needed in order to reduce morbidity and mortality.

    Isolated renal vein thrombosis is a rare entity. We present a patient whose complaint of flank pain led to the diagnosis of a renal vein thrombosis. In this case, abdominal computed tomography angiography was helpful in diagnosing the nutcracker syndrome complicated by the renal vein thrombosis. Anticoagulation was started and three weeks later, CTA showed complete disappearance of the renal vein thrombosis. To treat the Nutcracker syndrome, we proposed left renal vein transposition that the patient consented to.

    We describe the case of a 23-year-old serviceman on overseas deployment who presented with a painful, swollen arm. Investigations showed an upper extremity deep vein thrombosis (UEDVT) of the right arm with an associated asymptomatic pulmonary embolism, which was treated with warfarin anticoagulation. Further investigation identified positional obstruction at the thoracic outlet, and the patient was diagnosed with Paget-Schroetter syndrome. He underwent elective resection of the first rib, and has now returned to normal duties. After review of the literature on UEDVT, it is suggested that in this military patient, the occurrence of an anatomical variant put him at risk of upper limb venous thrombosis, which was probably potentiated by the occupational factor of carrying a rifle. The external compression of the subclavian vein from the rifle butt and hypertrophied muscles, in addition to the anatomical variation, caused repetitive microtrauma of the vessel intima, which precipitated venous thrombosis.

    Renal actinomycosis is a rare infection caused by fungi of the genus Actinomyces. A 74-year-old male was admitted to our hospital because of gross hematuria with urinary symptoms and intermittent chills. Computed tomography of the abdomen showed thrombosis in the left renal vein and diffuse, heterogeneous enlargement of the left kidney. After nephrectomy, sulfur granules with chronic suppurative inflammation were seen microscopically, and the histopathological diagnosis was renal actinomycosis. Our case is the first report of renal actinomycosis with renal vein thrombosis.

    Limited data exist on thrombophilia and the risk of venous thrombosis (VT) during pregnancy and postpartum. The objectives of the present study were to investigate the role of haemostatic risk factors for pregnancy-related VT and their phenotypic expression in deep-vein thrombosis (DVT) and pulmonary embolism (PE). Total 313 cases with objectively verified first time VT and 353 controls were selected from a source population of 377,155 women with 613,232 pregnancies. The adjusted odds ratio (aOR) for pregnancy-related VT was 1.7 (95% confidence interval [CI] 1.1-2.8) for women with factor VIII >90th percentile. The aOR for VT for endogenous thrombin potential and D-dimer values >90th percentiles were 1.8 (95% CI 1.1-3.0) and 2.1 (95% CI 1.3-3.3), respectively. Factor IX >90th percentile or free protein S ≤the 5th percentile increased the risk for PE, and the aORs were 2.4 (95% CI 1.1-5.0) and 3.1 (95% CI 1.3-7.2), respectively. Women carrying the factor V Leiden (F5 rs6025) polymorphism, or who had reduced sensitivity to activated protein C (aPC) in the absence of F5 rs6025, had increased risk for DVT, with unadjusted ORs 7.7 (95% CI 4.7-12.7) and 3.5 (95% CI 2.2-5.4), respectively. Women with a history of pregnancy-related VT showed activation of coagulation and had elevated factor VIII. Furthermore, high levels of factor IX and low levels of free protein S were associated with increased risk for PE, whereas aPC resistance and F5 rs6025 were risk factors for DVT and not PE.

DVT prophylaxis is essential in the management of trauma patients. Currently, the optimal VTE prophylaxis strategy for trauma patients is unknown. Traditionally, pelvic and lower extremity fractures, head injury, and prolonged immobilization have been considered risk factors for VTE; however it is unclear which combination of risk factors defines a high-risk group. Modalities available for trauma patient thromboprophylaxis are classified into pharmacologic anticoagulation, mechanical prophylaxis, and inferior vena cava (IVC filters. The available pharmacologic agents include low-dose heparin (LDH, low molecular weight heparin (LMWH, and factor Xa inhibitors. Mechanical prophylaxis methods include graduated compression stockings (GCSs, pneumatic compression devices (PCDs, and A-V foot pumps. IVCs are traditionally used in high risk patients in whom pharmacological prophylaxis is contraindicated. Both EAST and ACCP guidelines recommend primary use of LMWHs in trauma patients; however there are still controversies regarding the definitive VTE prophylaxis in trauma patients. Large randomized prospective clinical studies would be required to provide level I evidence to define the optimal VTE prophylaxis in trauma patients.

    Deep vein thrombosis (DVT) and pulmonary embolism (PTE) are known as venous thromboembolism (VTE). DVT occurs when a thrombus (a blood clot) forms in deep veins of the body, usually in the lower extremities. It can cause swelling or leg pain, but sometimes may occur with no symptoms. Awareness of DVT is the best way to prevent the VTE. Patients with trauma are at increased risk of DVT and subsequent PE because of coagulopathy in patients with multiple trauma, DVT prophylaxis is essential but the VTE prophylaxis strategy is controversial for the trauma patients. The risk factors for VTE includes pelvic and lower extremity fractures, and head injury.

    To evaluate the efficacy and safety of the Tempofilter II for the prevention of a pulmonary thromboembolism (PTE) in patients with lower extremity deep vein thrombosis (DVT). Between January 2007 and December 2008, thirteen patients with lower extremity DVT whom were implanted with the Tempofilter II to prevent PTE were analyzed. A chest CT was compared before and after filter placement, to evaluate effectiveness of preventing PTE. Clinical symptoms of PTE were checked. Fluoroscopy and a plain radiograph were examined to evaluate filter status. The tempofilter II was successfully inserted in 13 patients. Nine patients underwent endovascular treatment after filter insertion. Trapping of thrombus was evaluated by following CT, venography, and filter retrieval. Trapped thrombus was detected in four patients by CT or retrieved filter. Two patients showed a decrease in thrombus in a follow-up chest CT. Not all patients showed symptoms of PTE. One filter was surgically removed due to the detachment of the anchoring device. The placement and retrieval of the Tempofilter II is feasible and effective for the prophylaxis of PTE in patients with lower extremity DVT; especially for patients that underwent subsequent endovascular treatment

    This report details a 58-year-old gentleman who presented to his outpatient primary care physician's clinic several times over four weeks for ongoing epigastric pain radiating into his left flank, dry heaving, and constipation. He was presumed to have gastritis at each visit and prescribed escalating doses of proton pump inhibitors. Due to the unrelenting pain, he eventually was admitted to the hospital and diagnosed with splenic vein thrombosis after computed tomography imaging of the abdomen. Our literature search revealed that pancreatic pathology is overwhelmingly the contributing factor to splenic vein thrombosis. Our patient had prominent collateral vasculature, suggesting that his splenic vein thrombosis was chronic in nature and likely the cause of his ongoing abdominal pain. Splenic vein thrombosis is an uncommon cause of abdominal pain, but one that should be included in the treating physician's differential diagnoses when abdominal pain is ongoing despite medical therapy. Although he had no evidence of initial findings on radiography, our patient was eventually diagnosed with biopsy-proven pancreatic cancer. Our case report demonstrates how patients presenting with persistent or worsening abdominal pain despite the use of proton pump inhibitors or other acid reducing agents and potential 'red flag' findings such as decreased appetite and weight loss should be worked up for other potential sources of abdominal pathology.

    Varicosity of the pulmonary veins is a rare anomaly of the pulmonary vascular system. The varices do not usually change in size over years, do not cause symptoms and need no therapy. However, raised left atrial pressure can cause increase in the diameter of pulmonary vein varices. A case of lung vein varicosity in the right middle and upper lobe associated with coarctation of the aorta and an anomalous upper-middle lobe vein was observed over a period of 10 years. Increase in left atrial pressure (aortic and relative mitral regurgitation) led to enlargement of the pulmonary veins.

    Ovarian vein thrombosis is a rare postpartum complication (0.1%). It can be fatal, since it can lead to sepsis, pulmonary thromboembolisms and inferior vena cava or renal vein thrombosis. Computed tomography and magnetic resonance imaging are the techniques of choice for its diagnosis, while the value of ultrasound is limited due to its low sensitivity and specificity. We report the case of a woman who, during puerperium, developed thrombosis of right ovarian vein that presented clinical, ultrasonographic and computed tomographic features of appendicitis. We describe the radiological sings and stress the fact that this diagnosis should be suspected in puerperal women. (Author) 9 refs.

    Previous studies indicated that gout is a risk factor of cardiovascular diseases. This study aimed to determine if patients with gout have an increased risk of deep vein thrombosis (DVT) or pulmonary embolism (PE).We used the Longitudinal Health Insurance Database, a subset of the national insurance claim dataset, which enrolled 1 million Taiwanese to identify 57,981 patients with gout and 115,961 reference subjects matched by sex, age, and entry date of diagnosis. The risk of DVT and PE was analyzed using the Cox proportional hazards model.In this Taiwanese dataset observed from 2000 to 2010, we found the incidence of DVT was 5.26 per 10 person-years in the gout cohort, which was twofold higher than the incidence of 2.63 per 10 person-years in the reference cohort. After adjusting for age, sex, and 9 comorbidities, the hazard ratio (HR) of developing DVT was 1.66 (95% confidence interval [CI] = 1.37-2.01). Among patients with gout, the youngest age group had the highest increase in the risk of developing DVT (HR [95% CI] = 2.04 [1.24-3.37] for ages 20 to 49 years, 1.80 [1.28-2.51] for ages 50 to 64 years, and 1.45 [1.11-1.91] for ages ≥65 years). The incidence of PE was about one-fifth that of DVT in gout patients, but the effect of gout on the risk was similar (HR [95% CI] = 1.53 [1.01-2.29]).Our analysis confirmed that gout increased the risk of DVT and PE. Further exploration is needed in the future.

    Heparin-induced thrombocytopenia (HIT) is a life-threatening complication of heparin administration. Of the few reported cases of HIT-associated intra-abdominal thrombosis, none to our knowledge provide multidetector-row computed tomography (MDCT) imaging findings or emphasize its utility in diagnosis. We describe a case of HIT with MDCT images demonstrating extensive intra-abdominal thrombosis and end-organ complications including splenic rupture and pulmonary emboli. This case emphasizes the potential role of MDCT in the rapid detection of HIT-related thromboembolic complications in patients with nonspecific abdominal pain.

    Venous thromboembolism is a common cause of mortality among hospitalized patients and yet it is preventable through detecting the precipitating factors and a prompt diagnosis by specialists. The present study has been carried out in order to assist specialists in the diagnosis and prediction of the risk level of pulmonary embolism in patients, by means of artificial neural network. A number of 31 risk factors have been used in this study in order to evaluate the conditions of 294 patients hospitalized in 3 educational hospitals affiliated with Kerman University of Medical Sciences. Two types of artificial neural networks, namely Feed-Forward Back Propagation and Elman Back Propagation, were compared in this study. Through an optimized artificial neural network model, an accuracy and risk level index of 93.23 percent was achieved and, subsequently, the results have been compared with those obtained from the perfusion scan of the patients. 86.61 percent of high risk patients diagnosed through perfusion scan diagnostic method were also diagnosed correctly through the method proposed in the present study. The results of this study can be a good resource for physicians, medical assistants, and healthcare staff to diagnose high risk patients more precisely and prevent the mortalities. Additionally, expenses and other unnecessary diagnostic methods such as perfusion scans can be efficiently reduced.

    Cassia angustifolia (Senna), used as a laxative, is a plant from the Fabaceae family. It includes hydroxyanthracene glycosides, also known as Senna Sennoside. These glycosides stimulate the peristalsis of the colon and alter colonic absorption and secretion resulting in fluid accumulation and expulsion. In the literature, there are reports illustrating the hepatotoxic effects of Cassia angustifolia but there is no report of portal vein thrombosis caused by Cassia Angustifolia. A 42-year-old woman was admitted to the emergency department with a five-day history of worsening epigastric pain, anorexia, episodic vomiting, and intermittent fever. She reported that she had boiled dried senna leaves she had bought from herbalists and drank approximately 200 mL daily for two years. Color Doppler screening found an echogen thrombus obliterating portal vein bifurcation and the right branch. The lumen was obstructed at this level and there was no blood flow through it. Treatment with thrombolytics was unsuccessful. Severe hepatotoxicity senna use is unusual. The cause of senna-related hepatotoxicity is unclear but could be explained by the exposure of the liver to unusual amounts of toxic metabolites of anthraquinone glycosides. Chronic use of Cassia angustifolia may rarely be associated with portal vein thrombosis.

    Ovarian vein thrombosis is a rare, but potentially serious postpartum complication. In 80% of the cases, it occurs on the right side and in less than 6% on the left side; it is bilateral in 14% of cases. The usual clinical features include abdominal pain, fever and leucocytosis. However, the diagnosis is often complicated by other non specific signs and symptoms. Ovarian vein thrombosis may cause sepsis, pulmonary thromboembolism, and thrombosis of the inferior vena cava and the renal vein. The diagnosis can be established by CT scan or nuclear magnetic resonance imaging, which has a high sensitivity and specificity. Treatment for the ovarian vein thrombosis includes antibiotics and anticoagulation. The complications can sometimes be surgically managed. Prompt diagnosis and treatment can decrease the morbidity and the mortality. Nowadays, the fatal issue is rare as the appropriate treatment is quickly instaured.

    2013-01-01

    Background The worldwide EINSTEIN DVT and EINSTEIN PE studies randomized 8282 patients with acute symptomatic deep-vein thrombosis (DVT) and/or pulmonary embolism (PE) and, for the first time in trials in this setting, included patients in China. This analysis evaluates the results of these studies in this subgroup of patients. Methods A total of 439 Chinese patients who had acute symptomatic DVT (n=211), or PE with or without DVT (n=228), were randomized to receive rivaroxaban (15 mg twice daily for 21 days, followed by 20 mg once daily) or standard therapy of enoxaparin overlapping with and followed by an adjusted-dose vitamin K antagonist, for 3, 6, or 12 months. The primary efficacy outcome was symptomatic recurrent venous thromboembolism. The principal safety outcome was major or non-major clinically relevant bleeding. Results The primary efficacy outcome occurred in seven (3.2%) of the 220 patients in the rivaroxaban group and in seven (3.2%) of the 219 patients in the standard-therapy group (hazard ratio, 1.04; 95% confidence interval 0.36–3.0; p=0.94). The principal safety outcome occurred in 13 (5.9%) patients in the rivaroxaban group and in 20 (9.2%) patients in the standard-therapy group (hazard ratio, 0.63; 95% confidence interval 0.31–1.26; p=0.19). Major bleeding was observed in no patients in the rivaroxaban group and in five (2.3%) patients in the standard-therapy group. In fragile patients (defined as age >75 years, creatinine clearance <50 mL/min, and/or body weight ≤50 kg), the principal safety outcome occurred in four (8.9%) of the 45 patients who received rivaroxaban compared with seven (15.2%) of the 46 patients who received standard therapy. Conclusions In Chinese patients with acute symptomatic DVT and/or PE, rivaroxaban was as efficacious as enoxaparin followed by vitamin K antagonist therapy, with a similar safety profile. The relative efficacy and safety of rivaroxaban compared with enoxaparin/vitamin K antagonist were

    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.

    A young mother presented to a major trauma centre following a road traffic collision. Her admission CT traumagram demonstrated liver and renal lacerations, spinal and pelvic fractures with no abnormalities of the ovarian veins. Her inpatient course was uncomplicated other than a sustained, isolated raised C reactive protein. CT of the abdomen 1 week after injury demonstrated stable solid organ injuries and the additional, unexpected finding of a right ovarian vein thrombosis (OVT). A pragmatic approach was taken towards the management of the OVT given the haemorrhagic risk from her traumatic injuries. A multidisciplinary, consultant-led plan was made to slowly increase enoxaparin to a therapeutic dose under close surveillance and to then switch to warfarin following an outpatient consultation with a consultant haematologist. A MR venogram was performed after 3 months of anticoagulation, and this demonstrated complete resolution of the OVT and normal appearances of the ovary.

  5. Spontaneous Internal Jugular Vein Thrombosis: A Case Report

    Directory of Open Access Journals (Sweden)

    2010-12-01

    Full Text Available Internal jugular vein thrombosis (IJVT is an elusive vascular disease that is rarely seen, with potentially lethal complications such as sepsis and pulmonary embolism. Spontaneous IJVT is considered when no apparent predisposing cause of thrombosis is present. A previously healthy, 31-year-old woman presented to the university-based emergency department because of painless swelling in the right anterior side of her neck. Physical examination revealed a painless, soft and immobile mass in the right anterior side of her neck beneath the sternocleidomastoid muscle, without hyperemia or local heat. On ultrasonographic examination, a hyperechogenic mass was visualized around the thoracic entrance of the right internal jugular vein, which was suggestive of a thrombus. The patient was administered intravenous antibiotic and low-molecular-weight heparin followed by oral coumadin as anticoagulant therapy. Her complaints were relieved within 5 days. She was completely well after 6 months. Venous thrombosis generally results from impaired blood flow locally or systemically that leads to activation of coagulation. Primary care physicians should sustain a high index of suspicion in patients who present with undiagnosed swelling in the neck, or other signs and symptoms attributed to IJVT.

    The clinical manifestation of renal vein thrombosis varies with the speed and degree of venous occlusion. Such patients may be asymptomatic, have minor nonspecific symptoms such as nausea or weakness, or have more specific symptoms such as upper abdominal pain, flank pain, or hematuria. Acute scrotal pain is a very uncommon clinical expression of renal vein thrombosis. Here, we report a case of membranous glomerulonephritis-induced renal vein thrombosis presented with the symptom of acute scrotal pain caused by thrombosis-induced varicocele. This case report suggests that renal vein thrombosis should be considered in the diagnosis of acute scrotal pain; it also emphasizes that an investigation of retroperitoneum should be performed for adult patients with the sudden onset of varicocele.

    Neonatal renal vein thrombosis is the most common vascular condition in the newborn kidney, which could lead to serious complication in infants undergoing intensive care. In this study, we report the case of a preterm infant with left renal vein and inferior vena cava thrombosis, presented with gross hematuria, thrombocytopenia, transient hypertension, and adrenal hemorrhage. Supportive care was offered instead of heparin therapy or thrombolytic agents. In conclusion, our case teaches that, despite the lack of a clinically obvious shock event, renal vein thrombosis should be considered in a macrohematuric newborn without renal failure.

    Full Text Available Tuberculosis remains an infectious disease with high prevalence worldwide. An association between tuberculosis-induced inflammation and hypercoagulable state has been described in the literature. Deep vein thrombosis is a rare complication of the disease, and very few cases are reported worldwide. Furthermore, such manifestation is very rare in the paediatric age group. The paediatrician’s awareness of this phenomenon is important for early diagnosis and prompt treatment. Here, we report two cases of severe pulmonary tuberculosis associated with deep vein thrombosis in the pediatric age group.

    Plantar vein thrombosis is a rare condition, with only a handful of cases reported in the literature. The cause is unknown; however, the disease has been attributed to prior surgery, trauma, and paraneoplastic conditions. We present a case of a 32-year-old female runner with plantar vein thrombosis diagnosed on contrast-enhanced MRI and confirmed on ultrasound. The symptoms resolved with conservative treatment and evaluation revealed the presence of a prothrombin gene mutation and use of oral contraceptive pills. To our knowledge, this is the first case of plantar vein thrombosis diagnosed initially by MRI. Moreover, this case suggests that plantar vein thrombosis should be considered in patients with hypercoagulable states and plantar foot pain. (orig.)

    A 23-year-old female who presented with advanced renal failure was subsequently diagnosed with renal vein thrombosis and antiglomerular basement membrane (GBM) antibody disease. A previous case of renal vein thrombosis has been reported in association with anti-GBM disease, but to our knowledge, this is the first reported case in which the presentation of anti-GBM disease and renal vein thrombosis was concurrent. Further study is essential to understand if the association of anti-GBM disease and renal vein thrombosis as seen in our case was pure coincidence or is in fact occurs more frequently. It may be that the dual diagnosis is not made as establishing one sufficient diagnosis for renal failure may halt further investigations for additional diagnoses.

    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.

    Extrahepatic portal vein obstruction is a vascular disorder of liver, which results in obstruction and cavernomatous transformation of portal vein with or without the involvement of intrahepatic portal vein, splenic vein, or superior mesenteric vein. Portal vein obstruction due to chronic liver disease, neoplasm, or postsurgery is a separate entity and is not the same as extrahepatic portal vein obstruction. Patients with extrahepatic portal vein obstruction are generally young and belong mostly to Asian countries. It is therefore very important to define portal vein thrombosis as acute or chronic from management point of view. Portal vein thrombosis in certain situations such as liver transplant and postsurgical/liver transplant period is an evolving area and needs extensive research. There is a need for a new classification, which includes all areas of the entity. In the current review, the most recent literature of extrahepatic portal vein obstruction is reviewed and summarized.

    To determine the significance of patients' age and sex on the size of the thrombus in acute deep vein thrombosis, 420 consecutive phlebograms with acute deep vein thrombosis were studied. A significant correlation between the size of the thrombus and increasing age of the patient as well as the sex of male was noted. It is concluded that older patients and men often are at a high risk of pulmonary embolism at the time of diagnosis.

    Abdominal venous thrombosis may present either as Budd-Chiari syndrome (BCS) caused by hepatic vein or proximal inferior vena cava (IVC) obstruction or as an extra hepatic portal obstruction (EHPVO) caused by Portal vein thrombosis or mesenteric vein thrombosis, but a mixed involvement is uncommon. Multiple abdominal venous obstructions presenting with thrombosis of hepatic vein, IVC, portal vein and renal vein are very rarely seen . We are reporting a rare case with thrombosis of IVC, hepatic vein, portal vein and renal vein, with protein S and protein C deficiencies, which was managed by giving anticoagulant therapy.

    Treatment of prosthetic heart valve thrombosis using intravenous thrombolytics, although an acceptable alternative to surgery, is not complication free, and the literature has a dearth of data on the subject. This study analyzed the results of fibrinolytic treatment (FT) among a single-center group of patients with mechanical pulmonary valve thrombosis. Between 2000 and 2013, 23 consecutive patients with 25 episodes of pulmonary valve thrombosis received FT. The diagnosis of mechanical pulmonary valve thrombosis was established by fluoroscopy and echocardiography. Streptokinase (SK) was used in 24 cases and alteplase in 1 case. The FT was continued a second day for 14 patients (58.3%), a third day for 1 patient, and a fourth day for 1 patient. Echocardiography and fluoroscopy were performed every day until improvement of malfunction was achieved. Of the 23 patients, 19 had complete resolution of hemodynamic abnormalities after FT, 1 had partial resolution, and 2 showed no change. No patient had major complications. Five minor complications were detected, namely, fever, nausea, thrombophlebitis, epistaxi, and pain. Seven patients (30%) experienced recurrence of thrombosis, whereas four patients had surgery (biological pulmonary valve replacement) without re-thrombolytic therapy, one patient was treated with Alteplase, one patient received SK, and one patient received intense anticoagulation using heparin and warfarin. Overall, FT had a success rate of 84%. The results indicate that regardless of the time to pulmonary valve replacement and echocardiographic and fluoroscopic findings, FT was effective in most cases of mechanical pulmonary valve thrombosis. The efficacy increased with second-day thrombolytic therapy. Major complications were not common after lytic therapy for mechanical pulmonary valve thrombosis.

    Acute renal vein thrombosis can rapidly lead to significant impairment and eventual loss of renal function. Classically presenting with flank pain, hematuria, and laboratory markers consistent with acute kidney injury, therapeutic anticoagulation is the mainstay of treatment. However, endovascular surgery offers a safe and effective alternative for renal salvage in the setting of acute renal vein thrombosis. Described is the use of combined arteriovenous thrombolytic infusion for refractory renal vein thromboses to quickly and effectively decrease clot burden in the micro- and macrovenous circulations while limiting systemic exposure.

    2014-07-01

    Portal vein thrombosis in cirrhosis is a relatively common complication associated with the presence of an accompanying prothrombotic phenotype of advanced cirrhosis. The consequences of portal vein thrombosis are relevant because it can be associated with impaired hepatic function, might contraindicate hepatic transplantation and could increase morbidity in the surgical procedure. There is controversy concerning the most effective treatment of portal vein thrombosis, which is based on information that is seldom robust and whose primary objective is to achieve a return to vessel patency. Various studies have suggested that starting anticoagulation therapy early is associated with portal vein repatency more frequently than without treatment and has a low rate of complications. There are no proven data on the type of anticoagulant (low-molecular-weight heparins or dicoumarin agents) and the treatment duration. The implementation of TIPS is technically feasible in thrombosis without cavernous transformation and is associated with portal vein recanalization in a significant proportion of cases. Thrombolytic therapy does not appear to present an adequate balance between efficacy and safety; its use is therefore not supported for this indication. The proper definition of treatment for portal vein thrombosis requires properly designed studies to delimit the efficacy and safety of the various alternatives.

    Full Text Available Deep vein thrombosis (DVT has been reported to be 2-10 times commoner in HIV infected patients than in the general population. We report two cases of extensive unilateral deep vein thrombosis involving the lower limb in HIV infected patients on highly active antiretroviral therapy (HAART. Doppler ultrasound in the two patients revealed evidence of venous thrombosis from the femoral vein down to the posterior tibial veins. None of the patients had a history of acquired risk factors for DVT. Both patients responded well to anti-coagulants. A high index of suspicion may therefore be required to make the diagnosis and institute adequate management for this condition which has potentially life threatening consequences.

IVC agenesis (IVCA) is found in approximately 5% of cases of unprovoked lower extremity deep vein thrombosis in patients Renal vein thrombosis (RVT) is an extremely rare and unusual presentation of IVCA. We report a unique case of a 23-year-old previously healthy man presenting with infrahepatic IVCA-induced bilateral RVT with azygos and hemiazygos continuation. To our knowledge, this is the third reported case in the literature of IVCA-induced RVT and the first to affect the bilateral renal veins in the absence of any other thrombogenic risk factors or any lower extremity venous complications. We also present a literature review of IVCA-induced vein thrombosis and highlight the lack of literature to manage this condition.

    Portal vein thrombosis refers to an obstruction of blood flow in the portal vein; this rare disease can be both local and systemic. Local risk factors, accounting for about 70% of cases, can be abdominal cancers, inflammatory of infective diseases, surgical procedures or cirrhosis. A 62-year-old man, affected by hypertension and taking acetylsalicylic acid after a myocardial infarction in 1994, developed deep venous thrombosis on the right leg. Six months later the patient was admitted to the emergency unit due to abdominal pain. A CT scan revealed the presence of a complete splanchnic vein thrombosis and a primary tumor on the right kidney. The patient was treated with total parenteral nutrition and intravenous solution of heparin sodium first and then, because of occurrence of allergy, fondaparinux, with improvement of the abdominal pain. Subsequently he underwent right radical nephrectomy.

    This study compared the efficacy and complication rates of inferior vena cava (IVC) filters for calf vein thrombosis (CVT) vs conservative treatment with or without anticoagulation. Vascular laboratory studies of patients who had an isolated CVT (anterior and posterior tibialis, peroneal, soleal, and gastrocnemius veins) from April 2009 to January 2014 were retrospectively analyzed from a single institution. Of 647 patients with isolated CVT, 285 (44%) received an IVC filter, and 362 (56%) received medical treatment alone (38.9% surveillance, 11.6% prophylactic anticoagulation, and 49.4% therapeutic anticoagulation). Univariate, multivariate, propensity matching, and Kaplan-Meier analyses were performed on abstracted data, which included, but was not limited to, risk factors, treatment modalities, venous thromboembolism (VTE) complications (defined as propagation of deep vein thrombosis [DVT] or pulmonary embolism [PE]), bleeding complications, and IVC filter-related complications (ie, filter tilting >15°, perforation >3 mm, fracture, migration >10 mm). The overall incidence of PE in was 2.5% in the IVC filter group and 3.3% in the medical group (P = .27). The overall incidence of VTE complications (propagation of DVT, PE) was 35% for the surveillance group without anticoagulation, 30% in patients treated with prophylactic anticoagulation, and 10% in patients treated with therapeutic anticoagulation (P = .0003). Only a minority of patients underwent duplex ultrasound imaging after filter insertion. In the IVC filter group, the most common reasons that contraindicated anticoagulation were bleeding (35%) or recent surgery (27%). The number of IVC filter-related complications in the IVC filter group was 29 (10%). Because the IVC filter group was older (mean age, 65 vs 61 years, P = .004) and more likely to have a history of thromboembolic events (56% vs 16%, P filters in this study was associated with a 10% complication rate and did not significantly reduce the

    Portal vein thrombosis is one of the main prehepatic causes of portal hypertension. The most frequent causes of thrombosis in this localization, apart from hepatic cirrhosis, are the following: acute inflammatory diseases and abdominal cancers, traumas, proliferative diseases of the hematopoietic system. In recent years attention was given to disorders in hemostasis, such as thrombophilia, in the course of which thrombosis development is particularly common. The authors present 10 patients after an incident of portal vein thrombosis, in which primary hepatic pathology was excluded and tests directed at thrombophilia were performed. In seven patients abnormalities in the examined parameters were found, and what is more, in two cases they had a complex character and involved more than one parameter. In five patients hyperhomocysteinemia was found. Among them, in two patients there was also a decreased protein S activity and in one of them there was also APC-resistance. In the next two patients there were abnormalities in one of the examined parameters - APC-resistance. Hyperhomocysteinemia was found in all patients with idiopathic thrombosis, and in one of them there were concurrent changes in protein S activity and APC-resistance. In patients with the history of portal vein thrombosis diagnostics of thrombophilia should be performed.

In one Egyptian study, the possible circumstantial risk factors for portal vein thrombosis were found in 30% of cases:  19% neonatal sepsis, 8.7% umbilical catheterization, 6% severe gastroenteritis and dehydration. Another Egyptian study concluded that hereditary thrombophilia was common in children with PVT (62.5%, the commonest being factor V Leiden mutation (FVL (30%. Concurrence of more than one hereditary thrombophilia was not uncommon (12.5%. The first international publication on hepatic veno-occlusive disease (VOD in Egypt was in 1965 in children who rapidly develop abdominal distention with ascites and hepatomegaly. This disease was more frequent in malnourished children coming from rural areas; infusions given at home may contain noxious substances that were hepatotoxic and Infections might play a role. VOD of childhood is rarely seen nowadays. Data from South Mediterranean area are deficient and this may be attributable to reporting in local medical journals that are difficult to access.

The present study aimed to investigate the prevalence and characteristics of thrombosis of the superior vena cava and auxiliary branches in Chinese HD patients with an indwelling internal jugular venous catheter and to explore its risk factors.Methods Fifty-four patients on maintenance hemodialysis (MHD) with an indwelling catheter were enrolled in this cross-sectional study. The thrombosis of the internal jugular vein, subclavical vein, brachiocephalic vein and superior vena cava was assessed by vascular ultrasound. Collected were data on age, gender, ultrafiltration volume, Kt/V, blood pressure, levels of hemoglobin, serum albumin, lipid, calcium, and phosphorus, and parathyroid hormone.Results The patients were given short- or long-term double lumen central venous catheters. Among them, 42 patients had the catheter placed into the right internal jugular vein, and 12 patients into the left internal jugular vein. Different degrees of central venous thrombosis were found in 33 patients (61.1%). The prevalence of thrombosis in the jugular vein, brachiocephalic vein, subclavical vein and superior vena cava was 61.1% (33/54), 44.4% (24/54), 16.7% (9/54) and 5.6% (3/54), respectively. Among the 33 HD patients with central venous thrombosis, the percentages for one, two, three and four affected veins were 27.3% (9/33), 45.4% (15/33), 18.2% (6/33) and 9.1% (3/33), respectively. Twelve (12/33, 36.4%) of the 33 HD patients with central venous thrombosis had clinical symptoms. Nine patients (27.3%) had edema of the upper extremity and 3 (9.1%) had new-onset symptoms of pulmonary embolism such as cough, chest distress and short breath. The incidences of diabetes mellitus and malignant tumor and levels of lipoprotein a and homocysteic acid were significantly higher in the HD patients with central venous thrombosis than in those without

    Chylous ascites is defined as the accumulation of chyle in the peritoneum due to obstruction or rupture of the peritoneal or retroperitoneal lymphatic glands. Chylous ascites that arises from acute pancreatitis with portal vein thrombosis is very rare. We report here on a case of chylous ascite that was caused by acute pancreatitis with portal vein thrombosis, in which the patient showed an impressive response to conservative therapy with total parenteral nutrition and octerotide. We also review the relevant literature about chylous ascites with particular reference to the management of this rare disease.

    Full Text Available Deep vein thrombosis (DVT was considered a rare condition in the pediatric population, more recent data show a significant increase in incidence. DVT occurs due to an imbalance of hemeostasis. There are incriminated multiple risk factors, of which the most common is the central venous catheter. Imaging evaluation plays a crucial role in early diagnosis of the disease. Anticoagulant therapy is the first line of treatment, adapted existing protocols for adults. This article addresses the assessment and treatment of pediatric patients with deep vein thrombosis.

    The incidence of deep vein thrombosis (DVT), diagnosed by ascending phlebography, has been calculated retrospectively in a group of 14 869 obstetrical patients. The incidence was calculated to 0.13 per thousand antepartum and 0.61 per thousand postpartum. The study revealed that clinical signs and symptoms of thrombosis are very unreliable in pregnant women but more reliable in puerperal women. It is concluded that objective diagnosis of thrombosis is important in pregnant women, and ascending phlebography is a rewarding objective method to use in pregnant women.

    In patients with nephrotic syndrome, the presence of a hypercoagulable state is thought to give rise to a high incidence of thromboembolic phenomena. Renal vein thrombosis is a common complication in nephrotic patients, mainly in those with membranous nephropathy, and many other types of thromboembolic complications also occur. The mortality rate in nephrotic patients with thromboembolic complications may be significantly increased, with pulmonary emboli likely being the most common cause of death.

    Full Text Available Portal vein thrombosis is common in cirrhotic patients and results in increased morbidity and mortality. Transjugular intrahepatic portosystemic shunt (TIPS creation is a well-established therapy for refractory variceal bleeding and refractory ascites in patients who do not tolerate repeated large volume paracentesis. Experience and technical improvements have led to improved TIPS outcomes that have encouraged an expanded application. Complete portal vein thrombosis has come a long way from being a contraindication to an indication for TIPS procedure. As experience and technology have evolved, the ultrasound guidance transvenous access of portal vein from the hepatic vein help in overall higher success rate of performing the TIPS procedure and reducing the procedure-related complications.

    Full Text Available Tuberculosis is a common infectious disease with a high prevalence in developing countries and presents a major public health issue. Internal jugular vein (IJV thrombosis is a rare complication in tuberculous cervical lymphadenopathy. We report a case of 26-year male patient with a history of low-grade evening rise in fever, dry cough, loss of appetite, and loss of weight with swelling in lower neck on right side. Ultrasonography (USG neck showed well-defined hypoechoic lymph nodes posterior to right IJV and common carotid artery in the lower neck at level IV and in the right supraclavicular region showing central necrotic areas with adjoining IJV thrombosis. The association between tuberculosis and deep vein thrombosis is rare. Awareness of IJV thrombosis in isolated cervical lymphadenopathy needs high diagnostic suspicion and prompt treatment to avoid fatal complication. Our case is rare as there was isolated tuberculous cervical lymphadenopathy with adjoining IJV thrombosis. Both USG and computed tomography (CT are accurate and reliable radiological investigations for detecting IJV thrombosis along with cervical lymph nodes. They are useful in assessing surrounding soft tissue and fat planes and knowing the size and extent of cervical lymphadenopathy. USG is inexpensive and readily available for monitoring response to treatment.

    Vitelline veins are a pair of embryonic structures. The veins develop the portal vein system. Serious problems occur if the vitelline vein does not regress and becomes an aneurysm. Thrombus formation in the vitelline vein aneurysm could lead to portal vein thrombosis and portal hypertension unless promptly and correctly treated. Though vitelline vein aneurysm is an extremely rare anomaly, it rapidly progresses to portal vein thrombosis that requires prompt diagnosis and treatment. We reported a case of neonatal vitelline vein aneurysm and thrombosis that was cured by prompt operation. PMID:26665130

    Full Text Available Injuries to the pancreas by blunt trauma are uncommon. The association of pancreatic injury with acute portal vein thrombosis secondary to blunt trauma abdomen is furthermore rare. The early diagnosis of the pancreas with injury to the portal vein is challenging and difficult. These injuries are associated with high morbidity and mortality, particularly if the diagnosis is delayed. Accurate and early diagnosis is therefore imperative and computed tomography plays a key role in detection. We present a case of child with a rare combination of pancreatic laceration and acute portal vein thrombosis following a blunt trauma to the abdomen. With extensive literature search we found no such cases has been described previously.

    Full Text Available Ambarish Pandey, Nivedita Patni, Mansher Singh, Randeep GuleriaDepartment of Medicine, All India Institute of Medical Sciences, New Delhi, IndiaAim: Deep vein thrombosis (DVT and pulmonary thromboembolism (PE are important causes of morbidity and mortality in medically ill patients. This study was done to assess risk factors and prophylaxis given for DVT and PE in newly admitted medically ill patients during the first two weeks of their hospital stay at a tertiary care center hospital in India.Methods: All patients within one week of their admission in intensive care unit (ICU and wards were enrolled in the study after an informed written consent. Patients who had DVT prophylaxis within the past month or any contraindications for DVT prophylaxis were excluded. A structured proforma was designed and effective risk stratification for DVT was done. Patients were followed for up to two weeks to record any changes in the risk categories and document any signs of PE or DVT if present. Any prophylaxis given for DVT or PE was noted.Results: Seventy-five percent of patients had the highest risk for DVT and PE. Only 12.5% had DVT prophylaxis within the first two days of admission. Within two weeks of admission, 30.8% of patients were discharged, and 16.2% died. 72.6% of the patients still in the wards belonged to the highest risk category. Clinical signs and symptoms of DVT and PE were present in 25.8% and 9.8% of patients, respectively after the second week of admission. 86% of symptomatic patients belonged to the highest risk category initially and none of them received any prophylaxis. 21.6% of the highest risk category patients died within two weeks of their admission. A statistically significant correlation was found between mortality and risk score of the patients for DVT and between lack of prophylaxis and mortality (p < 0.05.Conclusion: A significant risk for DVT and PE exists in medically ill patients, but only a small proportion of the patients

    M.R. Ramesh Babu

    2013-01-01

    Full Text Available Deep vein thrombosis (DVT is caused by obstruction of blood flow of deep veins in upper and lower limb. One of the precipitating factors for DVT is surgery under general anesthesia exceeding 30 min. However, there are very few reports of DVT associated with surgery of oral and maxillofacial region. In this paper we report two cases of DVT involving left ilio-femoropopliteal deep vein in one patient treated for fractured left angle of mandible and left peroneal vein in the other patient treated for oral sub mucous fibrosis. Clinical and color Doppler examination were performed to diagnose the condition and were referred to vascular surgical unit of higher institute for further management. These cases illustrates any surgery of maxillofacial region is not free from risk of DVT, which can cause fatal pulmonary thromboembolism.

    Full Text Available Central venous catheter insertion and cancer represent some of the important predisposing factors for deep venous thrombosis (DVT. DVT usually develops in the lower extremities, and venous thrombosis of the upper extremities is uncommon. Early diagnosis and treatment of deep venous thrombosis are of importance, because it is a precursor of complications such as pulmonary embolism and postthrombotic syndrome. A 47-year-old woman visited our department with painful swelling on the left side of her neck. Initial examination revealed swelling of the region extending from the left neck to the shoulder without any redness of the overlying skin. Laboratory tests showed a white blood cell count of 5,800/mm3 and an elevated serum C-reactive protein of 4.51 mg/dL. Computed tomography (CT of the neck revealed a vascular filling defect in the left internal jugular vein to left subclavian vein region, with the venous lumina completely occluded with dense soft tissue. On the basis of the findings, we made the diagnosis of thrombosis of the left internal jugular and left subclavian veins. The patient was begun on treatment with oral rivaroxaban, but the left shoulder pain worsened. She was then admitted to the hospital and treated by balloon thrombectomy and thrombolytic therapy, which led to improvement of the left subclavian venous occlusion. Histopathologic examination of the removed thrombus revealed adenocarcinoma cells, indicating hematogenous dissemination of malignant cells.

    Cerebral venous thrombosis is a rare condition with various clinical presentations which may delay diagnosis. It is frequently associated with severe consequences. We present the first documented case of thrombosis of the great cerebral vein in a hemodialysis patient. A 29-year-old female patient with end-stage renal disease of unknown etiology was admitted to a hospital with altered consciousness and nausea. Severe headache in the right parietal area had started 2 days before. On examination, she was in the poor overall condition, dysartric, with a severe nystagmus. Urgent brain multislice computerized tomography and magnetic resonance imaging revealed thrombosis of the great cerebral vein with hypodense zones in hypothalamus, thalamus and basal ganglia. She was treated with heparin bolus of 25000 IU with a favorable outcome. Detailed examination demonstrated increased lupus anticoagulant (LA) 1 and LA2 and increased LA1/LA2. Control magnetic resonance imaging performed 1 year later revealed multiple vascular lesions within the brain. Acetylsalicylate was introduced in therapy. Thrombosis of the cerebral veins should be suspected in patients with end-stage renal disease, altered neurological status and signs of increased intracranial pressure.

    AIM: To research the etiology, portal vein thrombosis and other features of Budd-Chiari syndrome (BCS)patients prospectively.METHODS: A total of 75 patients (40 female, 35 male) who were diagnosed between January 2002 and July 2004 as having BCS were studied prospectively.Findings from on physical examination, ultrasonography,duplex ultrasonography and venography were analyzed.Hemogram and blood chemistry were studied at the time of diagnosis and on each hospital visit. Bone marrow examination and immune phenotyping were performed by a hematologist when necessary. Protein C, S, antithrombin Ⅲ, activated protein C resistance,and anticardiolipin antibodies, antinuclear antibodies,and anti ds-DNA were studied twice. The presence of ascite, esophageal varices, and portal thrombosis were evaluated at admission and on every visit.RESULTS: At least one etiological factor was determined in 54 (72%) of the patients. The etiology could not be defined in 21 (28%) patients. One etiological factor was found in 39, 2 factors in 14 and 3 factors in 1 patient.The most common cause was the web (16%), the second was Hydatid disease (11%), the third was Behcet's disease (9%). Portal vein thrombosis was present in 11 patients and at least one etiology was identified in 9 of them (82%).CONCLUSION: Behcet's disease and hydatid disease are more prominent etiological factors in Turkey than in other countries. Patients with web have an excellent response to treatment without signs of portal vein thrombosis while patients having thrombofilic factors more than one are prone to develop portal vein thrombosis with worse clinical outcome.

    2011-03-01

    The authors report on a rare case of neonatal scrotal oedema occurring concurrently with pain upon palpation of the spermatic cord on the first day of life. An ultrasound examination showed poor perfusion of the left testicle and a thrombosis of the left renal vein; intraoperative exploration indicated necrosis of the left testicle without signs of torsion. Gorged vessels with paravasal bleeding were found in the spermatic cord. The authors hypothesise that necrosis of the testicle may result from haemorrhagic infarction caused by renal venous thrombosis. Acute scrotal discolouration with pain upon palpation in neonates is usually attributed to testicular torsion. The authors report a case where these symptoms had a different cause.

    We performed a systematic review to determine best practice for the management of patients with chronic or subacute subclavian vein thrombosis. This condition is best managed with surgical excision of the first rib followed by long-term anticoagulation. Interventional techniques aimed at restoring patency are ineffective beyond 2 weeks postthrombosis. Additional therapeutic options should be made based on the severity of symptoms as well as vein status. Patients with milder symptoms are given decompression surgery followed by anticoagulation whereas patients with more severe symptoms are considered for either a jugular vein transposition or saphenous patch based on the vein characteristics.

    2016-11-01

    Full Text Available Introduction: Wipple disease (WD is a rare chronic disease caused by the bacillus Tropheryma whipplei. Constitutive, rheumatologic, gastrointestinal, cardiac, cerebral, lymphatic, cutaneous, and ophthalmological signs are possible systemic symptoms. However, thrombotic manifestations are rarely described as “stroke-like syndrome” or arterial thrombosis. Diagnosis is based on clinical manifestations and pathological examination. Laboratory findings may include anemia, leukocytosis, and thrombocytosis. Objective: We report a case of venous thrombosis as initial manifestation of WD. Case Report: We describe the case of a 53-year-old male with iliofemoral vein thrombosis followed by intermittent diarrhea, loss of appetite, abdominal distension, and bloating. A mild malnutrition state with a weight loss of 13 kg, pallor (+/4 +, presence of lower-limb edema (+/4 +, and hypertympanic distended abdomen occurred. Laboratory tests on admission revealed anemia, positive inflammatory activity tests, and normal coagulation. Endoscopic examination showed villous edema with white dotted infiltrates in the second duodenal portion and intestinal lymphangiectasia in the terminal ileum. Pathological examination revealed numerous macrophages with positive periodic acid-Schiff inclusions. Venous Doppler ultrasound showed extensive deep thrombosis on the left lower limb and recanalization of the femoral vein in the right lower limb. The patient was treated with ceftriaxone and enoxaparin sodium, which led to an improvement of gastrointestinal and thrombosis symptoms. Comments: Hypercoagulability, endothelial damage, vasculitis, and blood stasis are present in T. whipplei infection, which are associated with the activation of inflammatory mechanisms as well as procoagulant and thromboembolic events. WD should be part of the differential diagnosis of diseases that cause venous thrombosis of unknown origin.

    2016-01-01

    Full Text Available Pulmonary vein thrombosis (PVT is rather an uncommon condition which presents nonspecifically and is usually associated with lung malignancy and major pulmonary surgery. Rarely could no cause be found. It causes increased pulmonary venous pressure leading to pulmonary arterial vasoconstriction and subsequent pulmonary arterial hypertension and subsequently can cause cor pulmonale if not addressed in timely fashion. Other associated complications like peripheral embolization and stroke have also been reported. This case emphasizes the importance of maintaining high index of clinical suspicion especially when CT pulmonary angiogram is negative for pulmonary embolism.

  5. Cerebral Vein Thrombosis Misdiagnosed and Mismanaged

    Directory of Open Access Journals (Sweden)

    P. K. Sasidharan

    2012-01-01

    Full Text Available Cerebral venous thrombosis (CVT should be considered in the differential diagnosis of all unexplained CNS disorders of sudden onset. Etiological factors are often subclinical forms of several common thrombophilic states occurring together, rather than the typical inherited and rare causes. Diagnosis is missed because of the heterogeneity in clinical presentation and etiological factors. In several patients with the so called idiopathic CVT nutritional deficiencies and lifestyle issues are more important factors in pathogenesis, rather than single rarer causes. High index of suspicion is the key to diagnosis. Clinical skill has to be fine tuned to diagnose the problem and to identify all the etiological factors. Radiology is essential for diagnosis but relying on radiology alone will lead to missing several cases and even erroneous diagnosis. It is inappropriate to proceed prematurely to laboratory investigations, forgetting proper clinical evaluation by studying diet, lifestyle, and environment of the patients. Success in managing lies in identifying all the contributory causes and correcting all of them giving excellent outcome almost always. Clinical observations based on case series and sharing of such information alone are the means to arrive at a consensus in diagnosis and management.

    A 17-year-old female presented with an isolated pelvic vein thrombosis (PVT) which was not visualised at the first compression ultrasound scan of the femoral vein. Isolated PVT should be suspected when the patient demonstrates the possible symptoms of a deep vein thrombosis with unilateral leg swelling extending to the groin and a negative compression ultrasound scan of the femoral vein. Supplemental ultrasound scan with Doppler flow, computed tomography or magnetic resonance venography are alternative diagnostic modalities if PVT is suspected.

    Fatal pulmonary embolism is the third most common cause of death after major trauma. We hypothesised that the Trauma Embolic Scoring System (TESS) would have adequate calibration and discrimination in a group of severely injured trauma patients in predicting venous thromboembolism (VTE), and could be used to predict fatal and non-fatal symptomatic pulmonary embolism. Calibration and discrimination of the TESS were assessed by the slope and intercept of the calibration curve and the area under the receiver operating characteristic curve, respectively. Of the 357 patients included in the study, 74 patients (21%) developed symptomatic VTE after a median period of 14 days following injury. The TESS predicted risks of VTE were higher among patients who developed VTE than those who did not (14 versus 9%, P=0.001) and had a moderate ability to discriminate between patients who developed VTE and those who did not (area under the receiver operating characteristic curve 0.71, 95% confidence interval 0.65 to 0.77). The slope and intercept of the calibration curve were 2.76 and 0.34, respectively, suggesting that the predicted risks of VTE were not sufficiently extreme and overall, underestimated the observed risks of VTE. Using 5% predicted risk of VTE as an arbitrary cut-point, TESS had a high sensitivity and negative predictive value (both ≥0.97) in excluding fatal and non-fatal pulmonary embolism. The TESS had a reasonable ability to discriminate between patients who developed VTE and those who did not and may be useful to select different strategies to prevent VTE in severely injured patients.

    Accurate assessment of residual thrombosis is of clinical importance for diagnostic baseline imaging, and may be of value in risk stratification for recurrent venous thromboembolism (VTE). This study evaluated the interobserver reliability of the measurement of residual thrombosis in patients 6 months after a first unprovoked deep vein thrombosis (DVT) of the leg. All enrolled patients received two ultrasound examinations by two independent blinded ultrasound technicians 5-7 months after their first unprovoked DVT. In total, 49 patients completed the two baseline ultrasound examinations. During the examinations, the presence of residual thrombosis was evaluated. If residual thrombosis was present, a detailed description of the size and location was reported. After all ultrasound results had been collected, the interobserver agreement was calculated by use of the kappa statistics, Pearson correlation, and the Bland-Altman plot. Furthermore, the clinical implications of interobserver reliability were examined. The interobserver reliability of the assessment of whether residual thrombosis is present was very good (κ = 0.92). The interobserver reliability of the measurement of residual thrombosis was good (r2 = 0.648), with a limited number of patients being misclassified. For the assessment of the percentage of residual occlusion, the interobserver reliability was fair (r2 = 0.357). Our results suggest that the interobserver reliability for measurement of residual thrombosis is high, and that the variability introduced by interobserver reliability has minimal clinical implications. Our study is important for the use of baseline imaging for the diagnostic and prognostic management of recurrent VTE. © 2012 International Society on Thrombosis and Haemostasis.

    Long-term anticoagulant treatment is highly effective in preventing recurrent Venous Thrombo-Embolism (VTE) in patients with idiopathic Deep Vein Thrombosis (DVT) of the lower limbs, though associated with an increased risk for major bleeding that may offset the benefits of anticoagulation. Accordingly to recent guidelines, patients with idiopathic DVT should be treated for at least 3 months and then should be evaluated for the risk-benefit ratio of long-term therapy. However, such 'time for decision' is often unclear and the optimal duration of VKA remains debatable. In recent studies, markers for the assessment of the individual risk for recurrent thrombosis have been proposed, which can be of help to establish the optimal duration of VKA treatment; among them, the D-dimer (D-d) assay and the Residual Vein Thrombosis (RVT) assessment by Compression Ultra-Sonography (CUS) were shown to be the most suitable. Studies' results showed that negative results of these parameters after 3 to 6 months of therapy, identify a group of patients at low-risk for recurrent thrombosis in whom VKA treatment can be withheld. In the present review we will discuss advantages and potential limits of using these individual markers for the management of patients with a first episode of DVT of the lower limbs.

    Full Text Available Portal vein thrombosis (PVT is commonly classified into acute (symptom duration <60 days and absence of portal carvernoma and portal hypertension and chronic types. However, the rationality of this classification has received little attention. In this study, 60 patients (40 men and 20 women with PVT were examined using contrast-enhanced computed tomography (CT. The percentage of vein occlusion, including portal vein (PV and superior mesenteric vein (SMV, was measured on CT image. Of 60 patients, 17 (28.3% met the criterion of acute PVT. Symptoms occurred more frequently in patients with superior mesenteric vein thrombosis (SMVT compared to those without SMVT (p<0.001. However, there was no significant difference in PV occlusion between patients with and without symptoms. The frequency of cavernous transformation was significantly higher in patients with complete PVT than those with partial PVT (p<0.001. Complications of portal hypertension were significantly associated with cirrhosis (p<0.001 rather than with the severity of PVT and presence of cavernoma. These results suggest that the severity of PVT is only associated with the formation of portal cavernoma but unrelated to the onset of symptoms and the development of portal hypertension. We classified PVT into complete and partial types, and each was subclassified into with and without portal cavernoma. In conclusion, neither symptom duration nor cavernous transformation can clearly distinguish between acute and chronic PVT. The new classification system can determine the pathological alterations of PVT, patency of portal vein and outcome of treatment in a longitudinal study.

    2011-01-01

    Full Text Available 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.

    Deep vein thrombosis remains a source of adverse outcomes in surgical patients. Deep vein thrombosis is preventable with prophylactic intervention. The success of noninvasive mechanical modalities for prophylaxis relies on compliance with correct application. The goals of this project were to create a guideline that reflected current evidence and expert thinking about mechanical modalities use, assess compliance with mechanical modalities, and develop strategies to disseminate an evidence-based guideline for deep vein thrombosis prophylaxis.

    Thromboembolism is a major complication of nephrotic syndrome. Renal vein thrombosis and deep vein thrombosis are relatively common, especially in membranous nephropathy. However, the incidence of portal vein and superior mesenteric vein (SMV) thrombosis in patients with nephrotic syndrome is very rare. To date, several cases of portal vein thrombosis treated by anticoagulation therapy, not by thrombolytic therapy, have been reported as a complication of nephrotic syndrome. Here, we report a case of portal, splenic, and SMV thrombosis in a patient with a relapsed steroid dependent minimal change disease who was treated successfully with anticoagulation and thrombolytic therapy using urokinase. Radiologic findings and his clinical conditions gradually improved. Six months later, a complete remission of the nephrotic syndrome was observed and the follow-up computed tomography scan showed the disappearance of all portal vein, splenic vein, and SMV thrombi.

    2002-01-01

    Full Text Available Pulmonary thromboembolism is a clinical and pathophysiological condition caused by occlusion of pulmonary arteries by thrombotic embolus. Deep venous thrombosis needn't necessarily be evident. Acute renal insufficiency is a syndrome manifested by rapid decrease or even complete urinary retention which may be due to obturation of renal arteries by a thrombus. The condition is clinically manifested by hematuria, oliguria, anuria and death due to uremia. Case Report The patient had a history of disease and a chest X-ray finding both irrelevant for establishing the working diagnosis. Blood gas analysis presented prominent hypoxemia with hyperventilation and ECG finding exhibited right heart overload, pointing to pulmonary thromboembolism. On the third day of treatment with heparin, the patient developed hematuria, oliguria and excessive elevation of nitrogen in blood as a sign of acute renal insufficiency, leading to fatal outcome. Autopsy revealed deep venous thrombosis of the left femoral vein, with massive pulmonary thromboembolism and thrombosis of both femoral arteries, inducing acute renal failure. Discussion Although the patient had a typical radiologic presentation of pulmonary thromboembolism, treatment with heparin was initiated on the basis of his blood gas analysis and ECG findings. Deep venous thrombosis was not clinically evident and acute renal failure could not be explained during patient's lifetime. Conclusion This is a rare case of acute renal failure due to a rare occurrence of bilateral acute thrombosis of renal arteries.

    Vipera berus has a wide geographical distribution throughout Central and Northern Europe. The symptoms after a bite usually are mild, life threatening symptoms are mainly described in children. We describe a case of popliteal vein thrombosis of the right leg after systemic envenoming with Vipera berus venom after a bite in the right hand by a female Vipera berus in the alpine region of Styria, Austria. Changes of the plasmatic coagulation system were obvious in our patient. These changes were due to an activation of the coagulation system and might be the reason for the thrombotic event in this usually healthy young male person.

    Renal vein thrombosis is a complication of the nephrotic syndrome presumably related to compression of renal veins by edematous parenchyma and a concomitant hypercoagulable state. The diagnosis has been made by demonstrating marked widening of the left renal vein as it crosses horizontally anterior to the aorta on computed tomography. Inferior venacavography confirmed the presence of thrombosis within the vessels. CT is suggested as a method for noninvasive imaging of the renal veins which might eliminate the need for venography.

    Full Text Available Background: Deep venous thrombosis (DVT of lower limbs is one of the most common cause for the majority of deaths caused by pulmonary embolism. Many medical and surgical disorders are complicated by DVT. Most venous thrombi are clinically silent. B-mode and color Doppler imaging is needed for early diagnosis of DVT to prevent complications and sequalae of DVT. Aim and Objectives: The objectives of the following study were to evaluate the role of Doppler as an imaging modality in diagnosing DVT of lower limbs, to study the spectrum of findings on Doppler ultrasound in patients with DVT. Materials and Methods: Retrospective descriptive analysis of 78 patients of DVT diagnosed on Doppler. Results: Nearly 74% of the patients were males and 26% were females with majority belonging to fifth decade (26%. 75 (96.1% cases showed unilateral while 3 (3.9% cases showed bilateral lower limb involvement. In our study, predominant distribution of thrombus was found to be in above knee region with 69/78 (88.5% patients having thrombus in the superficial femoral vein. Popliteal vein was involved in 54/78 (69.2% patients. Complete thrombosis was observed in 54/78 (69% cases, while partial thrombosis was observed in 24/78 (31% cases. Subacute stage was seen in 42 cases (53.8%, acute stage in 23 cases (29.5% while chronic stage in 13 cases (16.7%. 71 cases (91% had multiple contiguous segmental involvement, whereas 7 cases (9% had isolated vein involvement. Conclusion: Color Doppler is useful in diagnosing DVT in symptomatic and at risk patients and provides a non-invasive method of investigation. It is also helpful in evaluating the site, extent and stage of thrombus.

    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.

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

    Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but might also occur in absence of an overt liver disease. Several causes, either local or systemic, might play an important role in PVT pathogenesis. Frequently, more than one risk factor could be identified; however, occasionally no single factor is discernable. Clinical examination, laboratory investigations, and imaging are helpful to provide a quick diagnosis, as prompt treatment might greatly affect a patient’s outcome. In this review, we analyze the physiopathological mechanisms of PVT development, together with the hemodynamic and functional alterations related to this condition. Moreover, we describe the principal factors most frequently involved in PVT development and the recent knowledge concerning diagnostic and therapeutic procedures. Finally, we analyze the implications of PVT in the setting of liver transplantation and its possible influence on patients’ future prognoses. PMID:20066733

    In the last few years, several phase III clinical trials of new drug treatments for deep vein thrombosis (DVT) have been carried out or are about to finish. These drugs have a predictable and reliable pharmacokinetic and pharmacodynamic response and do not require monitoring and are consequently an attractive alternative for the treatment of a high proportion of patients with DVT. Dabigatran, edoxaban and idrabiotaparinux have been developed as an alternative to warfarin, and apixaban and rivaroxaban as one-drug only treatment for this disease, with a 1- or 3-week intensified phase of initial treatment, respectively. So far, the reported results show non-inferior efficacy and safety to warfarin or to conventional treatment. Therefore, the new anticoagulants will be particularly useful in patients with unstable INRs, warfarin incompatible pharmacologic interactions, and in those without access to regular coagulation monitoring.

    2011-12-01

    Full Text Available Abstract Background Ovarian vein thrombosis (OVT is a rare, but serious condition that affects mostly postpartum women. A high index of suspicion is required in order to diagnose this unusual cause of abdominal pain. Case presentation A 19-year-old woman at three days postpartum was admitted to our hospital because of severe right lower quandrant abdominal pain and fever 38.5'C. Physical examination revealed an acutely ill patient and right lower quadrant tenderness with positive rebound and Giordano signs. The patient underwent appendectomy which proved to be negative for acute appendicitis. Postoperatively fever and pain persisted and abdominal CT-scan with intravenous contrast agent demonstrated a thrombosed right ovarian vein. The patient was initiated on low-molecular weight heparin (LMWH and antibiotic treatment and a month later a new abdominal CT-scan showed a patent right ovarian vein. Discussion Pathophysiologically, OVT is explained by Virchow's triad, because pregnancy is associated with a hypercoagulable state, venous stasis due to compression of the inferior vena cava by the uterus and endothelial trauma during delivery or from local inflammation. Common symptoms and signs of OVT include lower abdomen or flank pain, fever and leukocytosis usually within the first ten days after delivery. The reported incidence of OVT ranges 0,05-0,18% of pregnancies and in most cases the right ovarian vein is the one affected. Anticoagulation and antibiotics is the mainstay of treatment of OVT. Complications of OVT include sepsis, extension of the thrombus to the inferior vena cava and renal veins, and pulmonary embolism. The incidence of pulmonary embolism is reported to be 13.2% and represents the main source of mortality due to OVT. Conclusions OVT is a rare condition, usually in the postpartum period. A high index of suspicion is required for the prompt diagnosis and management especially in cases that mimic acute abdomen.

    Full Text Available Portal vein thrombosis (PVT not associated with hepatocellular carcinoma is considered a frequent complication of liver cirrhosis but, unlike PVT occurring in non-cirrhotic patients, very few data are available on its natural history and management.  The reduced portal blood flow velocity is the main determinant of PVT but, as in other venous thromboses, multiple factors local and systemic, inherited or acquired often can concur with. PVT has a variety of clinical presentations ranging from asymptomatic to life-threatening diseases like gastroesophageal bleeding or acute intestinal ischemia. It is usually diagnosed by Doppler ultrasound but computed tomography and magnetic resonance imaging are useful to study the extent of thrombosis and the involvement of the abdominal organs. The risk of bleeding mainly determined by the presence of gastroesophageal varices and clotting alterations causes concern for the treatment of PVT in cirrhotic patients. To date, anticoagulant therapy seems to be indicated only in patients awaiting liver transplantation. This review focuses on the definition of the subgroups of patients with cirrhosis that might benefit from treatment of PVT and examines the pros and cons of the available treatments in terms of efficacy, monitoring and safety, providing also perspectives for future studies.

    Although there is no other underlying disease, women can sometimes experience rare and serious diseases such as ovarian vein thrombosis (OVT) and renal vein thrombosis (RVT) after giving birth. The widespread development of thrombosis is treated for the first time in this study. Stasis, coagulation factor abnormalities, and intimal damage to the venous thrombosis risk can increase during pregnancy. It was mentioned that it diagnoses an abnormality in the hypercoagulability half of women with OVT. Despite the hypercoagulant abnormality observed in pregnant women, it was very unusual that the renal vein thrombosis led to this complication. It can lead to severe complication of OVT which can even cause death. It was the first time that the renal vein and ovarian vein thrombosis were observed in the postpartum period, and there was no coagulation abnormality. It is known that the thrombus in the postpartum period can be observed with the fever of unknown origin. The problematic, but rarely observed, postpartum disease such as ovarian venous thrombosis (OVT) is generally observed in the right ovarian vein. In this disease, avoiding the resulting laparotomy heparin and intravenous antibiotics is best solution for the patient. If it is to be noted a fever for unknown reasons, that it be thrombosis.

    2015-12-01

    Full Text Available Background Portal vein thrombosis is a fairly common and potentially life-threatening complication in patients with liver cirrhosis. The risk factors for portal vein thrombosis in these patients are still not fully understood. Objectives This study aimed to investigate the associations between various risk factors in cirrhotic patients and the development of portal vein thrombosis. Patients and Methods In this case-control study performed at the Shiraz organ transplantation center, Iran, we studied 219 patients (> 18 years old with liver cirrhosis, who were awaiting liver transplants in our unit, from November 2010 to May 2011. The patients were evaluated by history, physical examination, and laboratory tests, including factor V Leiden, prothrombin gene mutation, Janus Kinase 2 (JAK2 mutation, and serum levels of protein C, protein S, antithrombin III, homocysteine, factor VIII, and anticardiolipin antibodies. Results There was no statistically significant difference in the assessed hypercoagulable states between patients with or without portal vein thrombosis. A history of previous variceal bleeding with subsequent endoscopic treatment in patients with portal vein thrombosis was significantly higher than in those without it (P = 0.013, OR: 2.526, 95% CI: 1.200 - 5.317. Conclusions In our population of cirrhotic patients, treatment of variceal bleeding predisposed the patients to portal vein thrombosis, but hypercoagulable disorders by themselves were not associated with portal vein thrombosis.

    Portal vein thrombosis may occur in cirrhosis; nevertheless, its prevalence, and predictors are still elusive. To investigate this issue, the Italian Society of Internal Medicine undertook the "Portal vein thrombosis Relevance On Liver cirrhosis: Italian Venous thrombotic Events Registry" (PRO-LIVER). This prospective multicenter study includes consecutive cirrhotic patients undergoing Doppler ultrasound examination of the portal area to evaluate the prevalence and incidence of portal vein thrombosis over a 2-year scheduled follow-up. Seven hundred and fifty-three (68 % men; 64 ± 12 years) patients were included in the present analysis. Fifty percent of the cases were cirrhotic outpatients. Viral (44 %) etiology was predominant. Around half of the patients had a mild-severity disease according to the Child-Pugh score; hepatocellular carcinoma was present in 20 %. The prevalence of ultrasound-detected portal vein thrombosis was 17 % (n = 126); it was asymptomatic in 43 % of the cases. Notably, more than half of the portal vein thrombosis patients (n = 81) were not treated with anticoagulant therapy. Logistic step-forward multivariate analysis demonstrated that previous portal vein thrombosis (p portal vein thrombosis. Portal vein thrombosis is a frequent complication of cirrhosis, particularly in patients with moderate-severe liver failure. The apparent undertreatment of patients with portal vein thrombosis is a matter of concern and debate, which should be addressed by planning interventional trials especially with newer oral anticoagulants.

    Background D-dimer testing to rule out deep vein thrombosis is less useful in older patients because of a lower specificity. An age-adjusted D-dimer cut-off value increased the proportion of older patients (>50 years) in whom pulmonary embolism could be excluded. We retrospectively validated the eff

    This paper aims to analyze the impact of splenic vein thrombosis (SVT) on the hemodynamic parameters in hepatic portal vein system. Based on computed tomography (CT) images of a patient with portal hypertension and commercial software MIMICS, the patient's portal venous system model was reconstructed. Color Doppler ultrasound method was used to measure the blood flow velocity in portal vein system and then the blood flow velocities were used as the inlet boundary conditions of simulation. By using the computational fluid dynamics (CFD) method, we simulated the changes of hemodynamic parameters in portal venous system with and without splenic vein thrombosis and analyzed the influence of physiological processes. The simulation results reproduced the blood flow process in portal venous system and the results showed that the splenic vein thrombosis caused serious impacts on hemodynamics. When blood flowed through the thrombosis, blood pressure reduced, flow velocity and wall shear stress increased. Flow resistance increased, blood flow velocity slowed down, the pressure gradient and wall shear stress distribution were more uniform in portal vein. The blood supply to liver decreased. Splenic vein thrombosis led to the possibility of forming new thrombosis in portal vein and surroundings.

    The aim of this study is to analyze the incidence, risk factors, management, and follow-up of patients with portal vein thrombosis (PVT) undergoing primary orthotopic liver transplantation (OLT). Four hundred fifteen OLTs were performed in 391 patients. In 62 patients, partial (group 1; n = 48) or complete (group 2; n = 14) PVT was found at the time of surgery. Portal flow was reestablished by venous thrombectomy. In this study, we compare 62 primary OLTs performed in patients with PVT at the time of OLT with a group of 329 primary OLTs performed in patients without PVT (group 3) and analyze the incidence of PVT, use of diagnostic methods, surgical management, and outcome. We found no significant differences among the 3 groups for length of surgery, cold and warm ischemic times, and postoperative stay in the intensive care unit. With the piggyback technique, groups 1 and 2 had greater blood losses and required more blood transfusions than group 3. The early reoperation rate was greater in group 2. The incidence of rethrombosis was 4.8% (group 1, 2%; group 2, 14.3%). Reexploration and thrombectomy (2 patients) and retransplantation (1 patient) had a 100% mortality rate. In particular, the mortality rate of patients with complete PVT with extension into the splanchnic veins is high (33%). Three-month and 4-year patient survival rates were statistically similar in the 3 groups. The presence of PVT at the time of OLT is not a contraindication for OLT. However, if PVT extends into the splanchnic veins, the outcome is guarded.

    2016-07-01

    Pseudoaneurysm formation often complicates transfemoral interventional procedures. Nonsurgical treatment consists of femoral compression and thrombin injection under ultrasound guidance. We report a 74-year-old man who was diagnosed with a pseudoaneurysm, following coronary angiography. Duplex ultrasound revealed deep vein thrombosis of the ipsilateral common femoral vein. Ultrasound-guided thrombin injection was unsuccessfully performed, and the patient subsequently underwent surgical exploration for repair of the pseudoaneurysm and release of the venous compression. The increased local inflammation, because of the thrombosis, added in surgical difficulties. We conclude that early surgical intervention should be considered as a primary strategy in patients with femoral pseudoaneurysms and deep vein thrombosis secondary to femoral compression.

    A 49-year-old, previously healthy woman sought treatment for abdominal pain. Colonoscopy revealed ascending colon cancer. Computed tomography and angiography showed splenic metastasis and thrombosis extending from the splenic vein to the portal vein. She underwent right hemicolectomy, splenectomy, and distal pancreatomy. Histological findings showed no malignant cell in the splenic vein which was filled with organizing thrombus. We postulate the mechanism of splenic vein thrombosis in our case to be secondary to the extrinsic compression of the splenic vein by the splenic metastasis or by the inflammatory process produced by the splenic metastasis. In conclusion, we suggest that splenic metastasis should be added to the list of differential diagnosis which causes splenic vein thrombosis. In the absence of other sites of neoplastic disease, splenectomy seems to be the preferred therapy because it can be performed with low morbidity and harbors the potential for long-term survival.

    A 64-year-old woman underwent prophylactic inferior vena cava filter placement immediately after spinal surgery for pulmonary embolus prophylaxis. One week after surgery, acute renal failure developed, and she required hemodialysis secondary to filter migration with iliocaval and renal vein thrombosis. Pharmacomechanical thrombolysis was performed, with complete recovery of renal function and no evidence of recurrence on follow-up imaging. This report highlights an important and rare complication of filter placement and the importance of prompt thrombus debulking to preserve end organ function while reducing the risks of hemorrhagic complications. Pharmacomechanical thrombolysis allows prompt clearance of venous outflow channels and is attractive in patients with end-organ compromise and high risk for bleeding.

    Cortical vein thrombosis (CVT) is a rare disorder, and its diagnosis is challenging. The aim of our study was to evaluate the value of different imaging modalities for the detection of CVT. Thirteen patients with CVT, either isolated (n = 3) or in combination with sinus thrombosis (n = 10), and 20 control patients without any venous pathologies were included in this study. The analysis was performed independently by three blinded readers who evaluated the following imaging modalities and sequences separately: non-enhanced computed tomography (NCCT); multi-detector row CT angiography (MDCTA); diffusion-weighted (DWI), T1-weighted (T1w), PD-weighted (PDw), T2*-weighted (T2*w), and fluid-attenuated inversion recovery-weighted (FLAIRw) magnetic resonance (MR) sequences; as well as venous MR angiography (vMRA). The sensitivity, specificity, positive (PPV) and negative predictive values, and interobserver agreement of the different modalities were calculated. T2*w showed the highest sensitivity for the detection of CVT (97.4%), followed by T1w (70%). FLAIRw and vMRA had a sensitivity of 50% and 41.7%, respectively, whereas the sensitivity of NCCT, MDCTA, DWI, and PDw was below 30%. The specificity and PPV of all modalities was 100%, with good to perfect interobserver agreement. T2*w was the superior MR imaging sequence for diagnosing CVT. Besides T2*w, only T1w reached a sensitivity of over 50% for CVT, followed by FLAIRw, and vMRA. On the contrary, our results suggest that NCCT but also MDCTA might not be suitable for diagnosing CVT.

    Bilateral renal vein thrombosis is an unusual etiology of acute renal failure and usually is associated with nephrotic syndrome. We report a 77-year-old man, consulting in the emergency room for anuria that appeared 24 hours after a syncope. The patient was carrier of an inferior vena cava filter prophylactically installed 17 months earlier and was not receiving anticoagulation. Serum creatinine on admission was 5.45 mg/dl and blood urea nitrogen was 54 mg/dl. Computed tomography and Doppler ultrasonography showed an extensive thrombosis of inferior vena cava and both renal veins. Heparin therapy was started with a rapid recovery of renal function and diuresis.

    Limited literature regarding the incidence of cannula associated deep vein thrombosis (CaDVT) following veno-venous extracorporeal membrane oxygenation (VV ECMO) exists. The purpose of this study was to identify the incidence of post decannulation CaDVT and identify any associated risk factors. Forty eight patients were admitted between August 2014 and January 2016 to the Lung Rescue Unit were included in the study. Protocolized anticoagulation levels (partial thromboplastin time 45-55 second) and routine post decannulation DVT screening were in place during the study period. Forty-one (85.4%) patients had CaDVT. Of those with CaDVT, 31 (76%) patients were treated with full anti-coagulation therapy. 34 (76%) patients with right internal jugular cannulation had CaDVT at cannula site. Twenty-five (61%) patients had CaDVT in the lower extremity. (18 associated right femoral vein cannulation; 7 left femoral vein cannulation) 18 (44%) patients had both upper and lower extremity CaDVT. Overall, patients with CaDVT tended to be older, have a higher body mass index (BMI) and on ECMO longer (p=NS). Mean PTT during time on ECMO between patients that did and did not have CaDVT did not differ. No clinical evidence of pulmonary embolism was seen.

    Venous thrombus resolution sets up an early intense inflammatory reaction, from which vein wall damage results. Tissue response to injury includes matrix metalloproteinase (MMP) activation and extracellular matrix protein turnover. This study sought to determine the effect of exogenous MMP inhibition and its potential attenuation of early vein wall injury. Rats received treatment beginning 24 hr after a stasis venous thrombosis by near occlusive ligation and until harvest at day 7. Three groups were evaluated: (1) vehicle saline controls (NaCl), (2) low molecular weight heparin (LMWH; Lovenox, 3 mg/kg daily SQ), and (3) doxycycline (DOXY, 30 mg/kg daily PO). Thrombus size (mg/mm), levels of tumor necrosis factor alpha (TNF alpha) and D-dimer by colorimetric assay, and monocytes counts by immunohistochemistry were assessed. Vein wall assessment included stiffness by tensiometry, interleukin 1beta (IL-1 beta protein levels by enzyme-linked immunosorbent assay, MMP2 and -9 by zymography, and histological analysis of intimal thickness (IT). Comparisons were by t-test to control. p DOXY-treated groups (NaCl = 1.0 +/- 0.8, LWMH = 9 +/- 3, DOXY = 27 +/- 5 pg/mg protein, n = 6-8, p DOXY group (NaCl = 3.0 +/- 2.5, DOXY = 23 +/- 4.2 pg/mg protein, n = 5, p DOXY, compared to controls (NaCl = 0.33 +/- 0.05, LMWH = 0.17 +/- 0.03, DOXY = 0.43 +/- 0.09 N/mm, n = 5-7, p DOXY group at 7 days (NaCl = 26 +/- 3, LMWH = 38 +/- 17, DOXY = 6 +/- 3 pg/mg protein, n = 4-6, p DOXY = 0.8 +/- 0.20, n = 4-6, p DOXY groups (NaCl = 85 +/- 24, LMWH = 23 +/- 7( *), DOXY = 13 +/- 5 U/mg protein, n = 6-8, p DOXY did not alter the size of deep vein thrombosis, mildly altered thrombus composition, and differentially affected vein wall injury, despite similar reductions in early MMP9 activity. Whether exogenous MMP inhibition affects long-term vein wall fibrosis will require further study. Copyright 2010 Annals of Vascular Surgery Inc. Published by Elsevier Inc. All rights reserved.

    Pulmonary vein stenosis(PVS) is rare condition characterized by a challenging diagnosis and unfavorable prognosis at advance stages. At present, injury from radiofrequency ablation for atrial fibrillation has become the main cause of the disease. PVS is characterized by a progressive lumen size reduction of one or more pulmonary veins that, when hemodynamically significant, may raise lobar capillary pressure leading to signs and symptoms such as shortness of breath, cough, and hemoptysis. Image techniques(transesophageal echocardiography, computed tomography, magnetic resonance and perfusion imaging) are essential to reach a final diagnosis and decide an appropriate therapy. In this regard, series from referral centers have shown that surgical and transcatheter interventions may improve prognosis. The purpose of this article is to review the etiology, assessment and management of PVS.

  11. Splenic and portal vein thrombosis following laparoscopic splenectomy in a pediatric patient with chronic myeloid leukemia

    Directory of Open Access Journals (Sweden)

    Full Text Available CONTEXT: Splenic or portal vein thrombosis is a rare complication following splenectomy. CASE REPORT: We report a case of splenic and portal venous thrombosis in a 10-year-old girl with chronic myeloid leukemia who underwent laparoscopic splenectomy prior to bone marrow transplant. Clinical suspicion of such thrombosis should be high for patients who have had splenectomy. The diagnosis is confirmed by Doppler ultrasound or contrast-enhanced computed tomography; magnetic resonance imaging magnetic resonance angiography or arteriography can also be used. Proposals for postoperative screening protocols are discussed. Patients with primary myeloproliferative disorders are at increased risk of portal vein thrombosis, independent of surgical intervention, perhaps due to platelet dysfunction resulting from abnormalities of pluripotent stem cells. Marked splenomegaly (with larger draining veins is thought to increase the risk of thrombosis.

    Venous thromboembolism (VTE) is known as a common complication in surgical and non-surgical patients. We hypothesized that according to the underlying risk factors and the acute illness, the prevalence ofVTE in non-surgical patients admitted to hospital is widely underestimated. For three months each patient admitted to the department of internal medicine with an acute illness, but without known deep venous thrombosis (DVT) was investigated by ultrasound compression sonography. Patients' history, risk factors and extent of immobilisation were documented. In patients with newly detected DVT D-dimer and fibrinogen were measured as well as computer tomography scans performed. Follow-up investigations of the DVT population were performed at four weeks and three months. Six hundred seventeen patients (49.3% men) were included. In 16 patients (men = 7) a previously unknown thrombosis (2.6%) was detected, mainly in patients with acute cardio-pulmonary disease (56%) and the elderly (mean age 75.6 years). Eight patients had femoro-popliteal (50.0%), four a femoral (25.0%), and four a popliteal vein thrombosis (25.0%). Five had pulmonary embolism (31.3%). In patients with DVT D-dimer was 875 +/- 1,228 mg/l, fibrinogen 568 +/- 215 mg/dl and C-reactive-protein 58.54 +/- 73.65 mg/dl. One patient died from sepsis during hospitalisation, one died from sudden cardiac death at home. None of the other 14 surviving patients relapsed. The study shows a 2.6% risk for DVT in outpatients with acute illness admitted to the department of internal medicine. These data demonstrate the high risk of DVT is in non-surgical patients. Early prophylaxis has to be considered in internal medicine patients especially in the elderly.

    A previously healthy young man presented with acute renal failure due to extensive spontaneous deep vein thrombosis, including the inferior vena cava (IVC) and both renal veins. The patient was treated with selectively delivered thrombolytic therapy over a 7-day-period, which resulted in renal vein patency and complete recovery of renal function. A stent was placed over a segment stenosis of the IVC. No thrombophilic factors were identified. Bilateral renal vein thrombosis in young fit individuals is an unusual cause of acute renal failure. Thrombolytic therapy, even with delay, can completely restore renal function.

    Full Text Available Isolated obstruction (mainly due to thrombosis of the splenic vein usually results in left-sided portal hypertension and isolated fundal varice formation. This syndrome is a rare cause of gastrointestinal bleeding. Pancreatic diseases are among the most common etiologies of splenic vein obstruction. Renal disorders are rarely reported as a cause of splenic vein thrombosis. In the present article, a case of a 26-year-old woman with a perirenal abscess presenting with gastrointestinal bleeding as a complication of an isolated splenic vein thrombosis is described. The thrombosis could not be visualized with ultrasonography and angiography because of its extremely proximal localization. Fundal varices disappeared following splenectomy and nephrectomy. Follow-up at one year revealed the patient to be well both clinically and endoscopically.

    2014-09-01

    Full Text Available [b]Introduction[/b]. Chronic venous disease is a group of symptoms caused by functional and structural defects of the venous vessels. One of the most common aspects of this disease is the occurrence of varicose veins. There are many ways of prevention and treatment of varicose veins, but in Poland the leading one is still surgery. As in every medical procedure there is the possibility of some complications. One of them is deep vein thrombosis (DVT. The diagnosis of DVT can be difficult, especially when access to a specialist is limited, such as in case of rural patients. [b]The aim of the study.[/b] The aim of the study was estimation of the influence of LMWH primary prophylaxis on the formation of postoperative DVT, as well as sensitivity and specificity of clinical examination and D-dimer value in diagnosis of postoperative DVT in women. [b]Materials and methods[/b]. The study was conducted in a group of 93 women operated on in the Department of General, Vascular Surgery and Angiology at the Karol Marcinkowski University of Medical Sciences in Poznań, Poland. The patients had undergone a varicose vein operation and were randomly divided into two groups: A – 48 women receiving LMWH during two days of the perioperative period, B – 45 women receiving LMWH during seven days of the perioperative period. [b]Results[/b]. There was no significant difference in the postoperative DVT complications in both groups. The value of D-dimer > 0.987 mcg/ml and swelling > 1.5 cm of shin (in comparison to the preoperative period plays a significant role in diagnosis of DVT. [b]Conclusions[/b]. The extended primary prophylaxis with LMWH does not affect the amount or quality of thrombotic complications after varicose vein operation. If the DVT occurs, the evaluation of the D – dimer and careful clinical examination can be a useful method for its diagnosis.

    Full Text Available Superior mesenteric venous thrombosis is a rare & life threatening condition. We report a case of 18 years old boy presented to emergency department with pain abdomen, fever, Melena for almost week duration. Bowel sounds were absent since two days. With a preoperative diagnosis of peritonitis Patient was taken up for emergency laparotomy. Resection of gangrenous small bowel and end to end anastomosis was done. Intra operatively thrombus in SMV was found. Coagulation profile was normal except for elevated homocystine levels. Early postoperative period was stormy. Patient was started on LMV Heparin from day - 1. Pregangrenous changes were seen in contrast CT abdomen on Day - 4. We managed conservatively with anticoagulation therapy in the postoperative period. Pregangrenous changes disappeared with conservative management. Patient was shifted to oral warfarin and discharged on 3 rd week. Follow up Doppler USG abdomen revealed a portal vein of normal size & caliber with no evidence of thrombus. On postoperative follow up for one year, patient is doing well. Hyperhomocycteinemia is an independent predisposing factor to superior mesenteric venous thrombus.

    Renal vein thrombosis (RVT) with flank pain, and hematuria, is often mistaken with renal colic originating from ureteric or renal calculus. Especially in young and otherwise healthy patients, clinicians are easily misled by clinical presentation and calcified RVT. A 38-year-old woman presented with flank pain and hematuria suggestive of renal calculus on ultrasound. She underwent extracorporeal shock wave lithotripsy that failed, leading to the recommendation that percutaneous lithotomy was necessary to remove the renal calculus. In preoperative view of the unusual shape of the calculus without hydronephrosis, noncontrast computed tomography was taken and demonstrated left ureteric calculus. However computed tomography angiography revealed, to our surprise, a calcified RVT that was initially thought to be a urinary calculus. This case shows that a calcified RVT might mimic a urinary calculus on conventional ultrasonography and ureteric calculus on noncontrast computed tomography. Subsequent computed tomography angiography disclosed that a calcified RVT caused the imaging findings, thus creating a potentially dangerous clinical pitfall. Hence, it is suggested that the possibility of a RVT needs to be considered in the differential diagnosis whenever one detects an uncommon shape for a urinary calculus.

    This report describes two non-cirrhotic patients with portal vein thrombosis who underwent successful balloon occlusion retrograde transvenous obliteration (BRTO) of gastric varices with a satisfactory response and no complications. One patient was a 35-year-old female with a history of Crohn's disease, status post-total abdominal colectomy, and portal vein and mesenteric vein thrombosis. The other patient was a 51-year-old female with necrotizing pancreatitis, portal vein thrombosis, and gastric varices. The BRTO procedure was a useful treatment for gastric varices in non-cirrhotic patients with portal vein thrombosis in the presence of a gastrorenal shunt.

    Superficial vein thrombosis (SVT) increases the risk of venous thrombosis fourfold to sixfold. As most individuals with SVT do not develop venous thrombosis, additional risk factors may explain the risk of developing a venous thrombosis. In the Multiple Environmental and Genetic Assessment of risk factors for venous thrombosis study, we assessed the risk of venous thrombosis in individuals with previous SVT and a mild thrombotic risk factor (smoking or overweight/obesity), a strong risk factor (surgery, hospitalization, plaster cast immobilization, or malignancy), or a reproductive factor in women (oral contraception, postmenopausal hormone therapy, or pregnancy/puerperium). Individuals with previous SVT alone had a 5.5-fold (95% confidence interval [CI], 4.4-6.8) increased risk of venous thrombosis. This was 9.3 (95% CI, 7.2-12.1) combined with a mild thrombotic risk factor, 31.4 (95% CI, 14.6-67.5) with a strong risk factor, and 34.9 (95% CI, 19.1-63.8) in women with a reproductive risk factor. The highest separate risk estimates were found for SVT with surgery (42.5; 95% CI, 10.2-177.6), hospitalization (49.8; 95% CI, 11.9-209.2), or oral contraception (43.0; 95% CI, 15.5-119.3 in women). In conclusion, the risk of venous thrombosis is markedly increased in individuals with previous SVT who have an acquired thrombotic risk factor.

    External iliac artery endofibrosis describes an intimal subendothelial fibrosis leading to wall thickening and stenosis that has been described in high-performance athletes. There are anatomical, mechanical, and probably metabolic factors that may contribute to this pathology. Ankle-brachial index (ABI) measurement with exercise testing, duplex ultrasound, computed tomography (CT) or magnetic resonance (MR) angiogram, and ultimately arteriography help to make the diagnosis. Management can be conservative, but most cases require surgical intervention. External iliac vein stenosis and thrombosis in cyclists has rarely been described in the literature. We report a case of extensive left lower limb deep venous thrombosis (DVT) including the external iliac vein diagnosed in a 57-year-old athletic cyclist with a history of external iliac artery thrombosis.

    Deep venous thrombosis and pulmonary embolism are the two aspects of venous thrombo-embolism. Investigation of lower limb veins has been part of various diagnostic algorithms in the past 15 years. Recently, the combination of CT venography (CTV) of lower limbs and abdominal veins together with CT angiography of the pulmonary arteries has allowed a complete examination of venous thrombo-embolism in one session. The technical aspects, imaging findings, venous anatomy on CT, interpretative pitfalls, results and advantages of CT venography are reviewed. (orig.)

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

    Objective: To explore the effect of thrombolysis with anticoagulation treatment for early stage of deep vein thrombosis of lower extremity. Methods: The clinical data of 106 patients at the early stage of deep vein thrombosis (DVT) in the lower extremities treated by thrombolysis with anticoagulation and dispersion drugs were analyzed retrospectively. Results: The thrombolytic effect was significant. After treatment, the deep veins were recanalized without regurgitation in 75.3% of the patients. The total effective rate was 100%. Only three patients had hemorrhagic complication, but none of the patients died. Conclusion: Thrombolysis with anticoagulation treatment is an effective and safe method for DVT at the early stage.

    Isolated cortical vein thrombosis often produces a focal lesion. Because of the rapid development of collateral circulation, increased intracranial pressure has never been reported in a patient with isolated cortical vein thrombosis. The diagnosis of isolated cortical vein thrombosis is based mainly on MRI, catheter digital subtraction angiography, and histological findings, but may be challenging. We report a patient who presented with intermittent seizures and left-sided limb weakness. Her symptoms gradually progressed, and she eventually developed signs of increased intracranial pressure. Imaging studies showed a space-occupying lesion in the right frontal lobe of the brain. As we could not diagnose isolated cortical vein thrombosis based on the preoperative findings, surgical excision of the lesion was performed under general anesthesia. Histological examination showed destruction of the brain parenchyma with infiltration of macrophages, proliferation of reactive astrocytes and small vessels, and foci of hemorrhage. Further examination found that a number of small vessels in both the subarachnoid space and brain parenchyma were filled with thrombus, some of which was organized. Elastic fiber staining showed that the obstructed vessels were veins. We diagnosed isolated cortical vein thrombosis with atypical clinical features.

  15. Prevalence of deep vein thrombosis in patients with paraplegia caused by traumas

    2013-12-01

    Full Text Available BACKGROUND: Deep vein thrombosis is a common disease among people who are immobilized. Immobility is inherent to paraplegia and leads to venous stasis, which is one of the factors covered by Virchow's triad describing its development. Trauma is the primary cause of paraplegia and is currently increasing at a rate of 4% per year. OBJECTIVE: To determine the prevalence of deep vein thrombosis in paraplegic patients whose paraplegia was caused by traumas, using color Doppler ultrasonography for diagnosis. METHODS: This was a cross-sectional observational study of 30 trauma-induced paraplegia patients, selected after analysis of medical records at the neurosurgery department of a University Hospital in Curitiba, Brazil, and by a proactive survey of associations that care for the physically disabled. The prevalence of deep vein thrombosis was analyzed using 95% confidence intervals. RESULTS: Spinal cord trauma was the cause of paraplegia in 29 patients. The most common cause of trauma was gunshot wounding, reported by 17 patients. Deep vein thrombosis was diagnosed by color Doppler ultrasonography in 14 patients in the sample. The most often affected vein was the posterior tibial, in 11 patients. The left lower limb was involved three times more often than the right. Edema was observed in 25 individuals, cyanosis in 14, ulcers in 8 and localized increase in temperature in 13. CONCLUSIONS: Deep vein thrombosis was prevalent, occurring in 46.7% of the patients.

Six hundred and forty eight patients who underwent surgical procedures >1 hour were included in this study to find the incidence of deep vein thrombosis (DVT development postoperatively. AIMS AND OBJECTIVES Identifying the possible risk factors and to identify the subgroup of patients needing prophylaxis routinely after a surgical procedure. METHOD OF COLLECTION OF DATA Patients aged >15 years who underwent surgeries (APR, colostomies, abdominal surgeries, hernia repairs, MRM, thyroidectomies, perforation closure etc. lasting for more than one hour under spinal, epidural and general anaesthesia. Patients unwilling to take part in the study, patients on anticoagulant therapy and patients previously diagnosed with DVT or VTE were excluded from the study. PROCEDURE Clinical examination was carried out in the postoperative period to look for limb pain and swelling. D-dimer levels and Doppler USG were used for diagnosis. RESULTS AND CONCLUSION The incidence of DVT was 1.23% and the mean age group of the patients affected was 50.5 years. Male-to-female ratio was 1.28:1. OCP intake, smoking, higher BMI, major surgeries under GA and greater and postoperative immobilisation were important risk factors. Colonic surgeries had a greater chance of post-op DVT development. Duplex USG had a high sensitivity and specificity and thus can be considered the gold standard test for diagnosis of DVT, whereas D-dimer has low specificity and specificity thus not reliable for DVT diagnosis post-operatively.

    Portal vein thrombosis (PVT) is a rare but potentially life-threatening complication of laparoscopic splenectomy (LS) and can lead to bowel ischemia or portal hypertension. In childhood, this complication is reported in 5-10 % of the cases whereas it can be up to 50 % in adult population. Our aim was to evaluate PVT incidence after LS and associated risks factors. A retrospective chart review identified 37 children who underwent elective LS from 2005 to 2013. The main indications were spherocytosis or sickle cell disease. Median age and weight were respectively 7.4 years and 25.1 kg. Thromboembolic prophylaxis was not routinely given. Duration of surgery was 129 min and hospital length of stay 4 days. Doppler ultrasound scan (USS) was performed post-operatively in 26 cases. Post-operative course was uneventful in all but one patient. She was a 17 year-old girl previously operated for an ovarian tumor with hyperandrogenism. Histopathology revealed a splenic lymphoma. At day 4, a systematic USS showed a PVT extending in the portal branches. Therapeutic low molecular weight heparin was used and then transitioned to fluindione for 3 months. Follow-up USS performed at 1 and 4 months demonstrated complete resolution of the PVT. PVT after pediatric LS is a rare event in our series. Clinician should be cautious in oncologic cases and if very large spleen or if thrombocythemia >650.10(9)/L is present. If detected early, PVT can be treated efficiently. We therefore recommend a systematic USS during the first postoperative week.

    Deep-vein thrombosis (DVT) represents a serious complication in acute stroke patients with pulmonary embolus (PE) as a potential outcome. Prediction of DVT may help with formulating a proper prevention strategy. To assess of the risk of deep venous thrombosis (DVT) in acute stroke patients, we developed and validated a clinical score in a cohort study. Incidence of Deep Venous Thrombosis after Acute Stroke in China (INVENT-China) is a multicenter prospective cohort study. The potential predictive variables for DVT at baseline were collected, and the presence of DVT was evaluated using ultrasonography on the 14 ± 3 days. Data were randomly assigned to either a training data set or a test data set. Multivariate logistic regression analysis was used to develop risk scores to predict DVT in the training data set and the area under the receiver operating characteristic curve to validate the score in the test data set. From 2006-2007, 862 hospital-based acute stroke patients were enrolled in China. The overall incidence of DVT after acute stroke within two weeks was 12.4% (95%CI 10.3-14.7%). A seven-point score derived in the training data set (age [≥65 years = 1], sex [female gender = 1]), obesity [BMI ≥ 25 kg/m(2) = 1], active cancer [yes = 2], stroke subtype [cerebral hemorraghe = 1], muscle weakness [≥2 on Lower limb NIHSS score = 1] was highly predictive of 14-day risk of DVT(c statistic = 0.70, 95% CI, 0.64-0.76, P < 0.001), in the overall study population(c statistic = 0.65, 95% CI 0.59-0.70, P < 0.001). This clinical score may help identify acute stroke patients with high risk of DVT. In addition, it also serves as a platform to develop further models of DVT prediction in stroke patients based on clinical factors. © 2014 John Wiley & Sons Ltd.

    The morphological and functional effects of calcium-free and calcium-containing solutions on canine jugular vein intima were examined under conditions which closely resemble those techniques currently employed in peripheral vascular and aortocoronary bypass surgery. Veins that had been exposed only to calcium-containing solutions remained patent for the duration of the experimental period. Vein perfusion with a calcium-free solution, however, resulted in disruption of the jugular vein intima once calcium ions were reintroduced. Autogenous as a femoral arterial graft became thrombosed within 60 minutes. It is therefore suggested that vein grafts of autogenous origin be irrigated with calcium-containing solutions to prevent intimal damage and thrombosis.

    Deep vein thrombosis is an alarming medical emergency. Deep vein thrombosis or deep venous thrombosis (DVT) is the formation of a blood clot (thrombus) within a deep vein predominantly in the legs. Post-Coronary Artery Bypass Grafting deep vein thrombosis is a very rare medical condition relatively in Asian. Approximately 80% of deep vein thrombosis (DVTs) is clinically asymptomatic, 20% of those that actually demonstrate signs and symptoms can be easily confused with symptoms of other commonly presenting musculoskeletal disorders. Proper medical management can reduce patient's morbidity and further burden. A 50 years old diabetic Post-Coronary Artery Bypass Grafting gentleman had been suffering for left leg swelling, high grade fever and calf muscle pain for 5 days. He had absent Arteria Dorsalis Paedis pulse on left foot, Positive Homan sign and Wells score is 7. His left leg was hugely swelled. He had normal leg hair distribution. Duplex study of Left Leg-Deep Vein Thrombosis in left lower limb (Popliteal segment) with sign of recanalization. He is also a patient of anemia of chronic disease due to hemorrhoid. Several investigations have done to find the cause of his chronic anemia. His treatment was meticulous with complete bed rest, elevation of left lower limb, heparinization, oralrivaroxaban. He had rapid recovery following treatment. Post-Coronary Artery Bypass Grafting patient should be given post-operative enoxaparin (Low molecular weight Heparin) or Heparin for 3-5 days. Early diagnosis of the disease condition reduces morbidity. Combined treatment with Rivaroxaban and Heparin is of great clinical value and outcome in a case of Post-Coronary Artery Bypass Grafting Deep Vein Thrombosis patient.

    Antenatal renal vein thrombosis is a rarely described diagnostic finding, with variable consequences on kidney function. We present the case of an affected fetus, born at 35-week gestation, with intrauterine oligohydramnios and two small kidneys. A renal ultrasound carried out after birth confirmed the presence of prenatal abnormalities. Renal vein thrombosis was not diagnosed at the time. The baby died 20 days later of kidney failure, metabolic acidosis, and polypnea with severe hypotrophy. Autopsy revealed atrophied kidneys and adrenal glands. The vena cava had thrombosis occupying most of its length. The right renal vein was normal, while the left renal vein was threadlike and not permeable. Histologically, there was necrosis of the left adrenal gland with asymmetrical bilateral renal impairment and signs of ischemic and hemorrhagic lesions. A review of thrombophilia was carried out and a heterozygous mutation in Factor V was found in both the mother and the child.

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

    Full Text Available Clot formation within a deep vein is called deep vein thrombosis (DVT. It occurs in about 100 persons per 100,000 population each year in the United States and leads to about 600,000 pulmonary thromboembolism (PTE cases and also causes 60,000 deaths annually. For many years, unfractionated heparin (UFH and warfarin have been used for treatment of DVT and prevention of PTE. This approach needs hospitalization and necessitates close monitoring by partial thromboplastin time (PTT measurement. By development of low molecular weight heparin (LMWH the need for laboratory monitoring was resolved. In addition, some investigators also claimed that it is accompanied with less bleeding risk and better outcome. Accordingly, outpatient management of DVT became possible and nowadays American College of Chest Physicians (ACCP advocates outpatient therapy for DVT. This method has been shown to be safe and effective in presence of home adequacy criteria. Home adequacy is defined by ACCP as “well-maintained living conditions, strong support from family or friends, phone access, and ability to quickly return to the hospital if there is deterioration”. Yet, many physicians in Iran prefer to hospitalize all DVT patients because of their belief in the impossibility of outpatient treatment.

    Treatment of splanchnic vein thrombosis (SVT) is a clinical challenge due to heterogeneity of clinical presentations, increased bleeding risk, and lack of evidences from clinical trials. We performed an international registry to describe current treatment strategies and factors associated with therapeutic decisions in a large prospective cohort of unselected SVT patients. A total of 613 patients were enrolled (mean age 53.1 years, standard deviation ± 14.8); 62.6% males; the majority (468 patients) had portal vein thrombosis. Most common risk factors included cirrhosis (27.8%), solid cancer (22.3%), and intra-abdominal inflammation/infection (11.7%); in 27.4% of patients, SVT was idiopathic. During the acute phase, 470 (76.7%) patients received anticoagulant drugs, 136 patients (22.2%) remained untreated. Incidental diagnosis, single vein thrombosis, gastrointestinal bleeding, thrombocytopenia, cancer, and cirrhosis were significantly associated with no anticoagulant treatment. Decision to start patients on vitamin K antagonists after an initial course of parenteral anticoagulation was significantly associated with younger age, symptomatic onset, multiple veins involvement, and unprovoked thrombosis. Although a nonnegligible proportion of SVT patients did not receive anticoagulant treatment, the majority received the same therapies recommended for patients with usual sites thrombosis, with some differences driven by the site of thrombosis and the pathogenesis of the disease.

    The safest duration of anticoagulation after idiopathic deep vein thrombosis (DVT) is unknown. We conducted a prospective study to assess the optimal duration of vitamin K antagonist (VKA) therapy considering the risk of recurrence of thrombosis according to residual vein thrombosis (RVT). Patients with a first unprovoked DVT were evaluated for the presence of RVT after 3 months of VKA administration; those without RVT suspended VKA, while those with RVT continued oral anticoagulation for up to 2 years. Recurrent thrombosis and/or bleeding events were recorded during treatment (RVT group) and 1 year after VKA withdrawal (both groups). Among 409 patients evaluated for unprovoked DVT, 33.2% (136 of 409 patients) did not have RVT and VKA was stopped. The remaining 273 (66.8%) patients with RVT received anticoagulants for an additional 21 months; during this period of treatment, recurrent venous thromboembolism and major bleeding occurred in 4.7% and 1.1% of patients, respectively. After VKA suspension, the rates of recurrent thrombotic events were 1.4% and 10.4% in the no-RVT and RVT groups, respectively (relative risk = 7.4; 95% confidence interval = 4.9-9.9). These results indicate that in patients without RVT, a short period of treatment with a VKA is sufficient; in those with persistent RVT, treatment extended to 2 years substantially reduces, but does not eliminate, the risk of recurrent thrombosis.

    We report a case of renal vein thrombosis diagnosed at 27 weeks of gestation in a dichorionic twin pregnancy. The left kidney of one fetus was hyperechoic and enlarged with echoic streaks following the direction of interlobular veins and the loss of corticomedullary differentiation. In the following weeks, left kidney became smaller and echoic, and Doppler examination showed no flow in both artery and vein. The right kidney had totally normal appearance in the beginning, but it became enlarged and hyperechoic, and progressed into a small echoic kidney with no flow in artery and vein. In the postnatal ultrasound examination, both kidneys appeared hyperechoic with no vascularization in the hilum region. There was thrombosis in arteries and veins of both kidneys, as well as in the inferior vena cava. The investigation for thrombophilia resulted with the combined presence of heterozygote mutation in factor V Leiden and prothrombin 20210 genes.

    Objective:To study the relationship between inflammation and traumatic deep vein thrombosis (TDVT).Methods : A rat model of deep venous thrombosis was established by directly clamping femoral vein. Based on the different biological situations of femoral vein thrombosis and observation phases, 150 SD rats were divided into 7 groups. Inflammatory cells in vein wall of each group were counted. The fold change and cluster analysis were applied to study the change of gene expression during the development of venous thrombosis. Especially, the genes related to inflammation, fibrinolysis, coagulation of endothelium were analyzed in detail.Results: The inflammation cells in femoral vein wall were mostly neutrophilic granulocytes in Groups B, C and D, while they were lymphocytes in Groups E, F and G. Compared with Groups A, B, E and G, the inflammation cell counts in Groups C, D and F were much higher (P <0.05). The results of fold-change analysis showed that 2 504 genes ( Log 2 ratio ≥ 1 or≤-1 ) presented different expressions in the process of TDVT. Most of these genes' functions were not clarified so far and the genes with known functions were involved in inflammation, DNA-dependent transcription regulation, blood coagulation, fibrinolysis, etc. Among them, 23 genes related to inflammation had different expressions during TDVT. The cluster analysis showed that the expression changes of several genes, such as IL-1α, IL-1β, IL-6, Cinc2, corresponded with the development of femoral vein thrombosis.Conclusion: There is a close relationship between the genes related to inflammation and deep vein thrombosis induced by direct vascular trauma.

    The objective of this study was to determine the sequential CT findings of controlled hepatocellular carcinoma (HCC) with main portal vein (MPV) thrombosis with the use of transcatheter arterial chemoembolization and additional intra-arterial cisplatin infusion. From January 2004 to September 2006, 138 patients with HCC invading MPV were referred to the angiography unit of our institution for chemoembolization and additional intra-arterial cisplatin infusion. Until August 2008, seven (5%) of 138 patients were followed-up and found not to have tumor recurrence. CT scans were retrospectively reviewed by two radiologists, focusing on the following parameters: the extent of portal vein thrombosis, the diameter of the affected portal vein, and enhancement of portal vein thrombosis. The extent of portal vein thrombosis at the initial presentation was variable: left portal vein (LPV) and MPV (n = 1), right portal vein (RPV) and MPV (n = 3), as well as RPV, LPV and MPV (n = 3). The extent and diameter of the affected portal vein decreased during follow-up examinations. In addition, the degree of enhancement for tumor thrombi and serum alpha-feto-protein levels decreased after the transcatheter arterial chemoembolization. Portal vein thrombosis was found to be completely resolved in one patient, whereas residual thrombus without viability was persistent in six patients. If chemoembolization is effective in patients with HCC that invades the portal vein, the extent and enhancement of portal vein thrombosis is reduced, but residual thrombosis frequently persists for months or years, without evidence of a viable tumor.

    AIM: To test whether clamping during liver surgery predisposes to hepatic vein thrombosis.METHODS: We performed a retrospective analysis of 210 patients who underwent liver resection with simultaneous inflow and outflow occlusion.Intraoperatively, flow in the hepatic veins was assessed by Doppler ultrasonography during the reperfusion phase. Postoperatively, patency of the hepatic veins was assessed by contrast-enhanced CT angiography,when necessary after 3-6 mo follow up.RESULTS: Twelve pat ients (5.7%) developed intraoperative liver remnant swelling. However,intraoperative ultrasonography did not reveal evidence of hepatic vein thrombosis. In three of these patients a kinking of the common trunk of the middle and left hepatic veins hindering outflow was recognized and was managed successfully by suturing the liver remnant to the diaphragm. Twenty three patients (10.9%) who developed signs of mild outflow obstruction postoperatively, had no evidence of thrombi in the hepatic veins or flow disturbances on ultrasonography and contrast-enhanced CT angiography, while hospitalized. Long term assessment of the patency of the hepatic veins over a 3-6 mo follow-up period did not reveal thrombi formation or clinical manifestations of outflow obstruction.CONCLUSION: Extrahepatic dissection and clamping of the hepatic veins does not predispose to clinically important thrombosis.

  11. Deep venous thrombosis and pulmonary embolism in psychiatric settings

    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.

    Aims: In images of magnetic resonance and computed tomography (CT) there are visible angles between pulmonary veins and the coronary, transversal or sagittal section of body. In this study these angles are measured and defined as Projective Angles of pulmonary veins. Several possible influential factors and characters of distribution are studied and analyzed for a better understanding of this imaging anatomic character of pulmonary veins. And it could be the anatomic base of adjusting correctly the angle of the central X-ray of the angiography of pulmonary veins undergoing the catheter ablation of atrial fibrillation (AF). Method: Images of contrast enhanced magnetic resonance angiography (CEMRA) and contrast enhanced computer tomography (CECT) of the left atrium and pulmonary veins of 137 health objects and patients with atrial fibrillation (AF) are processed with the technique of post-processing, and Projective Angles to the coronary and transversal sections are measured and analyzed statistically. Result: Project Angles of pulmonary veins are one of real and steady imaging anatomic characteristics of pulmonary veins. The statistical distribution of variables is relatively concentrated, with a fairly good representation of average value. It is possible to improve the angle of the central X-ray according to the average value in the selective angiography of pulmonary veins undergoing the catheter ablation of AF.

    Isolation of the pulmonary veins by applying radiofrequency is an effective treatment for atrial fibrillation. One of the potential complications with higher clinical compromise utilizing this invasive technique is the occurrence of stenosis of one or more pulmonary veins. This complication can be treated by angioplasty with or without stent implantation, with an adequate clinical improvement, but with a high rate of restenosis.

    Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but several other causes might play an important role in PVT pathogenesis. We present a case of alcoholic chronic pancreatitis complicated by acute extensive PVT. The patient was managed conservatively with danaparoid sodium at first, but the thrombosis gradually extended. We then tried radiological intervention using the direct transhepatic and transjugular intrahepatic postsystemic shunt approaches. Although we were able to successfully catheterize the percutaneous transhepatic portal vein (PTP), we could not achieve recanalization of the portal vein. Therefore, PTP catheterization and systemic intravenous infusion of urokinase and heparin was performed to prevent further progression of the thrombosis and cavernous transformation was finally achieved. Computed tomography (CT) and magnetic resonance cholangiopancreatography revealed a pancreatic stone which had possibly induced dilatation of the tail duct and formation of a pancreatic pseudocyst and caused intractable pancreatitis. We performed endoscopic retrograde cholangiopancreatography and placed a stent in the pancreatic duct, which completely cured the pancreatitis. Retrospectively, the previous CT with curved multi-planar reconstruction was reviewed and a fistula was detected between the pancreatic pseudocyst and splenic vein. We concluded that the etiology of the PVT was not only inflammatory extension from pancreatitis but also a fistula between the pancreatic duct and the splenic vein.

    2012-03-01

    Full Text Available Abstract Background Approximately 80,000 patients each year are admitted to UK hospitals with an acute stroke and are immobile. At least 10% will develop a proximal Deep Vein Thrombosis in the first month and 1.5% a pulmonary embolus. Although hydration, antiplatelet treatment and early mobilisation may reduce the risk of deep vein thrombosis, there are currently no preventive strategies which have been clearly shown to be both effective and safe. Anticoagulation increases the risks of bleeding and compression stockings are ineffective. Systematic reviews of small randomized trials of intermittent pneumatic compression have shown that this reduces the risk of deep vein thrombosis in patients undergoing surgery, but that there are few data concerning its use after stroke. The CLOTS trial 3 aims to determine whether, compared with best medical care, best medical care plus intermittent pneumatic compression in immobile stroke patients reduces the risk of proximal deep vein thrombosis. Methods/Design CLOTS Trial 3 is a parallel group multicentre trial; with centralized randomisation (minimisation to ensure allocation concealment. Over 80 centres in the UK will recruit 2800 immobile stroke patients within the first 3 days of their hospital admission. Patients will be allocated to best medical care or best medical care plus intermittent pneumatic compression. Ultrasonographers will perform a Compression Duplex Ultrasound Scan to detect deep vein thrombosis in each treatment group at about 7-10 days and 25-30 days. The primary outcome cluster includes symptomatic or asymptomatic deep vein thrombosis in the popliteal or femoral veins detected on either scan. Patients are then followed up by postal or telephone questionnaire at 6 months from randomisation to detect later symptomatic deep vein thrombosis and pulmonary emboli and to establish their functional outcome (Oxford handicap scale and quality of life (EQ5D-3 L.

    Full Text Available Introduction. Portomesenteric thrombosis is increasingly recognized as a complication of laparoscopic sleeve gastrectomy (LSG. It often presents with abdominal pain. We present a mother and her son who both developed portal vein thrombosis (PVT after LSG. Case Description. A 43-year-old woman presented complaining of sudden severe abdominal pain, two weeks after she had uncomplicated laparoscopic sleeve gastrectomy. CT scan of the abdomen and pelvis with IV contrast showed portal vein thrombosis and SMV thrombosis. Two weeks later her son had the same LSG for morbid obesity and presented with the same clinical picture. Thrombophilia workup showed heterozygous prothrombin gene mutation. Conclusions. A high index of suspicion is necessary to diagnose PVT; although rare, it can be potentially lethal. Anticoagulation therapy should be initiated immediately to limit the morbidities and improve the outcome. Patients with family history of thrombophilia should be investigated prior to any bariatric surgery and nonsurgical alternative treatments for morbid obesity should be strongly encouraged.

    Obscure gastrointestinal bleeding is a common clinical scenario. In the upper gastrointestinal tract, gastric varices can be frequently overlooked on endoscopy, particularly if not suspected or volume depleted. We report a case of suspected gastrointestinal bleeding in a patient with a childhood history of pancreatitis, who also experienced severe epigastric pain while in hospital. After transfer to an academic medical centre, the presence of gastric varices was identified and presumed to be due to splenic vein thrombosis. Pancreatitis is the most common cause of splenic vein thrombosis and accords with the patient's history, even though it occurred many years previously. This case highlights the importance of recognising pancreatitis-induced splenic vein thrombosis as a possible aetiology for upper gastrointestinal bleeding.

    Full Text Available The pathophysiology of venous thrombosis is classically attributed to alterations in one or more components of Virchow’s triad: hypercoagulability, stasis, and damage to the vascular endothelium. Deep vein thrombosis (DVT may lead to pulmonary thromboembolism (PE, and the latter is culpable for many deaths annually in the United States; however, DVT as a complication of uterine leiomyoma has rarely been reported. We report a case of a 57-year-old woman whose death was due to a large pedunculated subserosal leiomyoma externally compressing the pelvic veins resulting in stasis and venous thrombosis leading to fatal PE. The association of large pelvic masses with venous thrombosis has clinical implications, since prophylactic surgery could be life-saving.

    Full Text Available We are reporting a case of a healthy 21-year-old male, with no significant past medical history, who was found to have an incidental nonocclusive deep vein thrombosis in the right internal jugular vein detected on a head MRI previously ordered for work-up of headaches. A follow-up upper extremity venous Doppler ultrasound confirmed the presence of a partially occlusive deep vein thrombosis in the right jugular vein. The case presented is unique for the reason that the patient is young and has no prior risk factor, personal or familial, for venous thrombosis except for associated polycythemia on clinical presentation.

    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.

    Objective To evaluate color Doppler ultrasonography (CDU) appearances of renal vein thrombosis (RVT) and its diagnostic value.Methods Ten patients with RVT were analyzed retrospectively. Renal structure, distributions of intrarenal flow signals, echogenicity, and flow fullness in main renal veins were observed with CDU. Resistance index (RI) was recorded from the waveforms of segmental or interlobar renal artery.Results Ten kidneys in nine patients were confirmed to have thrombus within the main renal veins, and one patient was confirmed to have thrombus within the small intrarenal veins. The appearances of the main renal vein thrombosis included full of solid echogenicity or strip echogenicity and complete or partial filling defect within the main renal veins, and absent or a few intrarenal venous flow signals in 70% of kidneys involved. The appearances of intrarenal vein thrombosis included obscure renal structure and no venous flow signal within the involved part of the kidneys. Reverse diastolic flow in the intrarenal artery had only a sensitivity of 36% (4/11) ; in other 7 kidneys without intrarenal arterial reverse diastolic flow, increased RI (mean, 0.84; range, 0.74-0.96) was found.Conclusion CDU is helpful for rapid clinical diagnosis and follow-up of RVT, and therefore can be the first imaging modality of choice for RVT.

    Pulmonary hypertension is a common cause of death among patients with sickle cell disease. This study investigates the use of pulmonary vein analysis to assist the diagnosis of pulmonary hypertension non-invasively with CT-Angiography images. The characterization of the pulmonary veins from CT presents two main challenges. Firstly, the number of pulmonary veins is unknown a priori and secondly, the contrast material is degraded when reaching the pulmonary veins, making the edges of these vessels to appear faint. Each image is first denoised and a fast marching approach is used to segment the left atrium and pulmonary veins. Afterward, a geodesic active contour is employed to isolate the left atrium. A thinning technique is then used to extract the skeleton of the atrium and the veins. The locations of the pulmonary veins ostia are determined by the intersection of the skeleton and the contour of the atrium. The diameters of the pulmonary veins are measured in each vein at fixed distances from the corresponding ostium, and for each distance, the sum of the diameters of all the veins is computed. These indicators are shown to be significantly larger in sickle-cell patients with pulmonary hypertension as compared to controls (p-values < 0.01).

    The creation of a transjugular intrahepatic portosystemic shunt (TIPS) is a critical procedure for the treatment of recurrent variceal bleeding and refractory ascites in the setting of portal hypertension. Chronic portal vein thrombosis remains a relative contraindication to conventional TIPS and options are limited in this scenario. Presented is a novel technique for management of refractory ascites in a patient with hepatitis C cirrhosis and chronic portal and superior mesenteric vein thrombosis secondary to schistosomiasis and lupus anticoagulant utilizing fluoroscopically guided percutaneous mesocaval shunt creation.

    Full Text Available A 65-year-old man presented to our hospital due to intermittent claudication and swelling in his left leg. He had Leriche syndrome and deep vein thrombosis. We performed endovascular therapy (EVT for Leriche syndrome, and a temporary filter was inserted in the inferior vena cava. He received anticoagulation therapy for deep vein thrombosis. The stenotic lesion in the terminal aorta was stented with an excellent postprocedural angiographic result and dramatic clinical improvement after EVT. This case suggests that EVT can be a treatment for Leriche syndrome.

    A 52-year-old man developed malignant peritoneal mesothelioma 17 years after radiotherapy for seminoma of the testis. Although asbestos exposure is considered to be the major risk factor for the development of malignant mesothelioma, prior therapeutic radiation has also been postulated as a causative factor. The unexplained appearance of ascites or pleural effusion within a previously irradiated area should be considered suggestive of malignant mesothelioma in any long-term survivor of cancer. In addition, the patient suffered a deep vein thrombosis four years before the diagnosis of mesothelioma. Deep vein thrombosis is a common complication of malignant disease, and is often the first clue to occult malignancy. (author)

    Full Text Available Arteriovenous graft for hemodialysis vascular access is a widely used technique with many advantages. However, it has crucial complications with graft thrombosis and infection. We recently experienced an unusual case of arteriovenous graft complication involving graft thrombosis related to fistula formation between the graft and the natural vein with infection. We diagnosed this condition using Doppler ultrasound and computed tomography angiography. Successful surgical treatment including partial graft excision and creation of a secondary arteriovenous fistula using an inadvertently dilated cephalic vein was performed. The dialysis unit staff should keep this condition in mind and try to prevent this complication.

    Isolated renal vein thrombosis is very rare without the presence of nephrotic syndrome. It is more common in the newborns and infants. Whereas major risk factors in adults are the procoagulant states such as protein C or S deficiency, factor V Leiden mutation, primary or secondary antiphospholipid syndrome, severe hypothyroidism, and trauma. Here, we report a case of isolated renal vein thrombosis associated with MTHFR-1298 and PAI-1 4G gene mutations. It should be noted that the presence of MTHFR-1298 and PAI-1 4G gene mutations together might be one of the examples of genetic mutation combinations that increase the likelihood of a thrombotic event.

    We experienced a case of deep vein thrombosis after spine surgery in the prone position with a central venous catheter (CVC). Posterior lumbar interbody fusion was performed on a 73-year-old female patient who was diagnosed with spinal stenosis. Accordingly, in the operation room under general anesthesia, two-lumen CVC were inserted into the left subclavian vein. The surgery was performed in the prone position with a Wilson frame. On the next day, there was a sudden occurrence of severe edema in the patient's left arm. By ultrasonography and computed tomography scanning, extensive deep vein thrombosis was observed in the left subclavian vein. The existence of a factor affecting blood flow such as the prone position may increase the risk of thrombus formation. Therefore, careful perioperative evaluation should be implemented.

    Cerebral sinus-vein thrombosis may lead to severe hemodynamic changes, elevated intracranial pressure (ICP), and brain edema. It is supposed that progression of the thrombus from the sinus into bridging and cortical veins plays a key role in the development of these pathophysiological changes, but this hypothesis lacks experimental proof. The aim of this study, using a novel animal model of sinus-vein thrombosis, was to evaluate the effects of a standardized occlusion of the superior sagittal sinus and its bridging and cortical veins on hemodynamic alterations, on brain water content, and on ICP in domestic pigs. In 10 animals, the middle third of the superior sagittal sinus was occluded with a catheter-guided balloon. Five of these pigs received an additional injection of 1 ml fibrin glue into the superior sagittal sinus anterior to the inflated balloon, leading to an obstruction of bridging and cortical veins. In five control animals the balloon was inserted but not inflated. Five pigs underwent cerebral angiography. Four hours after occlusion, the brains were frozen in liquid nitrogen, and coronal slices were examined for Evans blue dye extravasation, regional water content, and histological changes. Occlusion of the superior sagittal sinus alone did not affect ICP or cerebral perfusion pressure (CPP). The additional injection of fibrin glue caused an obstruction of cortical and bridging veins as well as severe increases in mean (+/- standard deviation) ICP to 49.4 +/- 14.3 mm Hg, compared with 8.3 +/- 4.5 mm Hg in sham-treated controls and 7.1 +/- 3.9 mm Hg in animals with occlusion of the superior sagittal sinus alone. There was also a steep fall in the mean CPP to 34.2 +/- 19.6 mm Hg compared with 96.4 +/- 13.8 mm Hg in the control group. White-matter water content anterior to the occlusion site was elevated to 81.9 +/- 3.7 gm/100 gm frozen weight in the fibrin group as compared to 70.7 +/- 2.2 gm/100 gm in controls. Posterior to the occlusion site, water

    When imaging a renal transplant, the combination of absent flow in the main renal vein and reversed diastolic flow in the intrarenal arteries is considered highly suggestive of renal vein thrombosis. We present a case of torsion of a transplant kidney presenting with identical findings. Renal transplant torsion in general is a rare entity, previously described only in intraperitoneally placed organs; this case is the first that we are aware of with torsion occurring in a retroperitoneally placed graft.

    Full Text Available PURPOSE Venous thromboembolism is a relevant social and health care problem for its high incidence, pulmonary embolism-related mortality and long-term sequelae which may be disabling (post-thrombotic syndrome and ulceration. PROCEDURES The aim of our work was to establish the presence of coagulation disorders (hypercoagulable states in the patients with deep vein thrombosis (DVT of the leg. Prospectively we have analyzed a group of 30 patients with echosono-graphicaly verified DVT of the leg who were admitted to the department of vascular surgery from August 1st 2000 to July 31st 2001.The following parameters were monitored: prothrombin time (PT partial thromboplastin time (PTT, fibrinogen (Fib, alpha 2 antiplasmin (A-2 AP, D-dimer (DD, antithrombin III (AT III and factor VII. FINDINGS Activation of the coagulation process was registered. The values of monitored coagulation parameters are shown in table 1. Plasma levels of monitored parameters in the patients with DVT of the leg were significantly higher than in the control subjects. CONCLUSION In patients with a DVT a hypercoagulable state is common finding. Some parameters of coagulation activity such as D-dimer might be of great interest in the diagnostic strategy of DVT.

    Deep vein thrombosis (DVT) is a component of venous thromboembolism (VTE), the other being pulmonary embolism (PE). Its incidence is 1 to 2/1.000/year and nearly 1/100/year after 80 years. The major complication of DVT is PE which occurs in about 1/3 of cases, is often asymptomatic but can be fatal. Another common complication, occurring in 20-50 % of cases is the post-thrombotic syndrome (PTS) which is likely to alter the quality of life. Several issues remain unanswered when considering DVT. The optimal management of distal DVT versus proximal DVT is not well codified. The diagnostic approach to DVT is essential : it is based on the estimation of clinical probability, the possible use of D-dimer test and compression ultrasonography. The new direct oral anticoagulants (NOACs) have been proven effective in the phase 3 studies but when to use them and which to choose in the real life ? Wearing compression stockings to prevent the SPT is recommended: what is the definition of compression stockings and is there some evidence of their efficacy ? The purpose of this article is to provide some useful information to primary care physicians to address a DVT.

    Deep vein thrombosis (DVT) and pulmonary embolism are major causes of morbidity and mortality in patients during hospitalization; previous studies have proposed that an advanced age of more than 60 years is a risk factor for these conditions. This study analyzes the relative risk of DVT in very elderly patients older than 90 years of age compared with elderly patients aged 80 to 89 years. The study was performed at the Department of Internal Medicine, University Hospital of Saarland, Homburg/Saar, Germany, between 2004 and 2012. After completing ultrasound examinations, 20 (64.52%, 12 [60%] female patients, mean age 91.8 ± 1.83 years) of the 31 patients in the study group and 132 (62.26%, 87 [65.91%] female patients, mean age 83.84 ± 2.66 years) of the 212 patients in the control group were diagnosed with DVT. An increased relative risk of DVT was not discovered in the very elderly patients (relative risk, 1.04; P = .80).

  1. Bed rest versus early ambulation with standard anticoagulation in the management of deep vein thrombosis: a meta-analysis.

    Full Text Available Bed rest has been considered as the cornerstone of management of deep vein thrombosis (DVT for a long time, though it is not evidence-base, and there is growing evidence favoring early ambulation.Electronic databases including Medline, PubMed, Cochrane Library and three Chinese databases were searched with key words of "deep vein thrombosis", "pulmonary embolism", "venous thrombosis", "bed rest", "immobilization", "mobilization" and "ambulation". We considered randomized controlled trials, prospective or retrospective cohort studies that compared the outcomes of acute DVT patients managed with early ambulation versus bed rest, in addition to standard anticoagulation. Meta-analysis pertaining to the incidence of new pulmonary embolism (PE, progression of DVT, and DVT related deaths were conducted, as well as the extent of remission of pain and edema.13 studies were included with a total of 3269 patients. Compared to bed rest, early ambulation was not associated with a higher incidence of new PE, progression of DVT, or DVT related deaths (RD -0.03, 95% CI -0.05∼ -0.02; Z = 1.24, p = 0.22; random effect model, Tau2 = 0.01. Moreover, if the patients suffered moderate or severe pain initially, early ambulation was related to a better outcome, with respect to remission of acute pain in the affected limb (SMD 0.42, 95%CI 0.09∼0.74; Z = 2.52, p = 0.01; random effect model, Tau2 = 0.04. Meta-analysis of alleviation of edema cannot elicit a solid conclusion because of significant heterogeneity among the few studies.Compared to bed rest, early ambulation of acute DVT patients with anticoagulation was not associated with a higher incidence of new PE, progression of DVT, and DVT related deaths. Furthermore, for the patients suffered moderate or severe pain initially, a better outcome can be seen in early ambulation group, regarding to the remission of acute pain in the affected limb.

    Venous complications in patients with acute pancreatitis typically occur as a form of splenic,portal,or superior mesenteric vein thrombosis and have been detected more frequently in recent reports.Although a well-organized protocol for the treatment of venous thrombosis has not been established,anticoagulation therapy is commonly recommended.A 73-year-old man was diagnosed with acute progressive portal vein thrombosis associated with acute pancreatitis.After one month of anticoagulation therapy,the patient developed severe hematemesis.With endoscopy and an abdominal computed tomography scan,hemorrhages in the pancreatic pseudocyst,which was ruptured into the duodenal bulb,were confirmed.After conservative treatment,the patient was stabilized.While the rupture of a pseudocyst into the surrounding viscera is a well-known phenomenon,spontaneous rupture into the duodenum is rare.Moreover,no reports of upper gastrointestinal bleeding caused by pseudocyst rupture in patients under anticoagulation therapy for venous thrombosis associated with acute pancreatitis have been published.Herein,we report a unique case of massive upper gastrointestinal bleeding due to pancreatic pseudocyst rupture into the duodenum,which developed during anticoagulation therapy for portal vein thrombosis associated with acute pancreatitis.

    Full Text Available Introduction: Literature is inconsistent whether patients with hypopituitarism have increased risk of thrombosis. Recent data has shown problems with the coagulation system in Sheehan′s syndrome (SS. Here, we describe a case of SS which presented with deep vein thrombosis. Objective: To describe a case of SS presenting as deep vein thrombosis. Case Report: A 30-year-old female was admitted to the general medicine ward with 1 month history of gradual onset swelling and pain in the left leg. The left calf diameter was 5 cm greater than the right. Doppler of the lower limbs revealed thrombosis in the left popliteal vein. Patient′s coagulation profile revealed a normal prothrombin time of 12 sec, activated partial thromboplastin time of 30 sec, positive D-dimer, negative protein C and protein S and normal titres of antinuclear antibodies. Echocardiography showed an ejection fraction of 52 percent. Endocrinology consultation was sought in view of clinical suspicion of hypothyroidism. Endocrinology review revealed a significant past history of primary postpartum hemorrhage, lactation failure and secondary amenorrhea since the delivery of the last child 6 years back. She had clinical features of growth hormone, thyroid hormone and adrenocorticotropic hormone deficiency. Hormonal analysis showed features of central hypothyroidism, secondary adrenal insufficiency and growth hormone deficiency which was subsequently confirmed by insulin tolerance test. Conclusion: SS patients may have increased risk of thrombosis

    AIM: To determine the clinical impact of portal vein thrombosis in terms of both mortality and hepatic decompensations(variceal hemorrhage, ascites, portosystemic encephalopathy) in adult patients with cirrhosis.METHODS: We identified original articles reported through February 2015 in MEDLINE, Scopus, Science Citation Index, AMED, the Cochrane Library, and relevant examples available in the grey literature. Two independent reviewers screened all citations for inclusion criteria and extracted summary data. Random effects odds ratios were calculated to obtain aggregate estimates of effect size across included studies, with 95%CI.RESULTS: A total of 226 citations were identified and reviewed, and 3 studies with 2436 participants were included in the meta-analysis of summary effect. Patients with portal vein thrombosis had an increased risk of mortality(OR = 1.62, 95%CI: 1.11-2.36, P = 0.01). Portal vein thrombosis was associated with an increased risk of ascites(OR = 2.52, 95%CI: 1.63-3.89, P < 0.001). There was insufficient data available to determine the pooled effect on other markers of decompensation including gastroesophageal variceal bleeding or hepatic encephalopathy. CONCLUSION: Portal vein thrombosis appears to increase mortality and ascites, however, the relatively small number of included studies limits more generalizable conclusions. More trials with a direct comparison group are needed.

    AIM: To summarize our methods and experience with interventional treatment for symptomatic acute-subacute portal vein and superior mesenteric vein thrombosis (PV-SMV) thrombosis. METHODS: Forty-six patients (30 males, 16 females,aged 17-68 years) with symptomatic acute-subacute portal and superior mesenteric vein thrombosis were accurately diagnosed with Doppler ultrasound scans, computed tomography and magnetic resonance imaging.They were treated with interventional therapy, including direct thrombolysis (26 cases through a transjugular intrahepatic portosystemic shunt; 6 through percutaneous transhepatic portal vein cannulation) and indirect thrombolysis (10 through the femoral artery to superior mesenteric artery catheterization; 4 through the radial artery to superior mesenteric artery catheterization).RESULTS: The blood reperfusion of PV-SMV was achieved completely or partially in 34 patients 3-13 d after thrombolysis. In 11 patients there was no PV-SMV blood reperfusion but the number of collateral vessels increased significantly. Symptoms in these 45 patients were improved dramatically without severe operational complications. In 1 patient, the thrombi did not respond to the interventional treatment and resulted in intestinal necrosis, which required surgical treatment.In 3 patients with interventional treatment, thrombi re-formed 1, 3 and 4 mo after treatment. In these 3 patients, indirect PV-SMV thrombolysis was performed again and was successful.CONCLUSION: Interventional treatment, including direct or indirect PV-SMV thrombolysis, is a safe and effective method for patients with symptomatic acutesubacute PV-SMV thrombosis.

    The current approach for deciding the duration of vitamin K antagonist (VKA) treatment after an episode of venous thrombo-embolism (VTE) is mainly based on the characteristic of the index event (3 months or longer in case of unknown/persistent risk factors, 3 months or less in case of removable causes). However, the length of anticoagulation should be tailored on the patient's risk for recurrent thrombosis as well as for bleeding, but such 'time for decision' is often unclear and the optimal duration of VKA remains debatable. The presence of persistent residual vein thrombosis and increased D-dimer levels after stopping therapy are predictors for recurrent deep vein thrombosis (DVT). Management strategies based on these parameters have been demonstrated to optimize the decision for VKA duration, as they establish the patient's intrinsic risk for recurrent events. This annotation discusses current practice and upcoming approaches regarding the length of VKA treatment after a first episode of DVT.

    Full Text Available We describe a 39-year-old male who presented with a fever of unknown origin, the diagnostic work-up of which disclosed an acute cytomegalovirus (CMV infection complicated by a partial superior mesenteric vein (SMV thrombosis. Further investigations revealed the presence of factor V Leiden mutation. Oral anticoagulant treatment with warfarin led to a complete recanalization of SMV two months after. A literature review on the association between CMV infection and portal system (PS thrombosis in immunocompetent patients was performed. We found that, in agreement with our case, in a minority of case reports patients did not complain of abdominal pain, but presented with a mononucleosis-like syndrome with malaise and prolonged fever and displayed a variable elevation of aminotransferase levels. Interestingly, most of them exhibited a limited extension of portal thrombosis. On the whole, these data suggest that PS thrombosis during acute CMV infection may be an underestimated complication.

    Renal vein thrombosis (RVT) is an uncommon condition in adults and may be caused by endothelial damage, stasis, or hypercoagulable states. RVT is commonly identified in patients with nephrotic syndrome or malignancy. We present the case of a 57-yearold man with no past medical history who presented with a 1-month history of abdominal pain, dysuria, and hematuria. Initial laboratory studies were consistent with acute kidney injury (AKI). Imaging revealed bladder distension, enlargement of the prostate, bilateral hydronephrosis, and left renal vein thrombosis extending into the inferior vena cava. His renal failure and presenting symptoms resolved with placement of a Foley catheter and ureteral stent. The patient was discharged on anticoagulation. Here, we report a rare case of RVT that appears to have occurred as a consequence of obstructive uropathy causing massive bladder distention resulting in compression of the renal vein.

    The aim of the study is to evaluate the practicability and therapeutic efficacy of (125)iodine seeds implantation percutaneously for portal vein tumor thrombosis (PVTT) in patients with hepatocellular carcinoma (HCC). Nineteen patients with HCC accompanied with PVTT received ultrasound-guided implantation of 8-30 (125)iodine seeds, 8 mm apart within the portal vein tumor thrombi. The patients were followed up postoperatively for a period of 3-22 months. The successful rates of the procedure, postoperative changes of liver and renal function, hemogram, complications and therapeutic response were monitored. (125)I seeds were successfully implanted in the portal veins in all patients without serious complications. During the follow-up period, the portal vein tumor thrombi all shrunk obviously. Percutaneous implantation of (125)iodine seeds into the portal vein is an effective and safe treatment for PVTT accompanying HCC.

    Full Text Available We present a rare case of hemoptysis secondary to isolated unilateral pulmonary vein atresia. Isolated pulmonary vein atresia is a rare condition in which patients typically acquire a diagnosis in infancy and early childhood [Mataciunas et al.; Pourmoghadam et al.]. Our patient presented during puberty with several previous episodes of hemoptysis prior to her admission and diagnosis. The initial diagnosis was suspected in our patient from chest computerized tomography (CT, and confirmed with cardiac catheterization and pulmonary angiography. Treatment aim is to preserve lung function and minimize irreversible pulmonary remodeling [Pourmoghadam et al.; Harrison et al.]. Conservative monitoring can be considered with milder or asymptomatic cases, while others may require preoperative collateral artery banding, surgical anastomosis between the pulmonary vein (PV & left atrium (LA and even pneumonectomy [Pourmoghadam et al.].

    2010-03-01

    Full Text Available Abstract Background Pulmonary veins (PVs are the most important sources of ectopic beats with the initiation of paroxysmal atrial fibrillation, or the foci of ectopic atrial tachycardia and focal atrial fibrillation. Elimination of nitric oxide (NO enhances cardiac triggered activity, and NO can decrease PV arrhythmogensis through mechano-electrical feedback. However, it is not clear whether NO may have direct electrophysiological effects on PV cardiomyocytes. This study is aimed to study the effects of nitroprusside (NO donor, on the ionic currents and arrhythmogenic activity of single cardiomyocytes from the PVs. Methods Single PV cardiomyocytes were isolated from the canine PVs. The action potential and ionic currents were investigated in isolated single canine PV cardiomyocytes before and after sodium nitroprusside (80 μM, using the whole-cell patch clamp technique. Results Nitroprusside decreased PV cardiomyocytes spontaneous beating rates from 1.7 ± 0.3 Hz to 0.5 ± 0.4 Hz in 9 cells (P Conclusion Nitroprusside regulates the electrical activity of PV cardiomyocytes, which suggests that NO may play a role in PV arrhythmogenesis.

    Full Text Available Abstract Introduction Adrenocortical carcinomas are rare aggressive tumors. Their annual incidence is approximately one to two per million among the population of the United States of America. Patients with active endocrine tumors often present with Cushing's syndrome accompanied by virilizing features. Conversely, patients with non-functioning tumors may present with symptoms related to a mass-occupying lesion, such as abdominal pain and flank pain. Although varicoceles and acute kidney injuries are common problems in medicine, they are uncommon presentations of these rare tumors and easy to miss. We report a case of a large adrenocortical carcinoma that presented as testicular pain, varicocele, and acute kidney injury secondary to renal vein thrombosis. Case presentation A 54-year-old Caucasian man with a left-sided varicocele presented to our emergency department with lower abdominal pain and a decrease in urination. Four months previously, he had noticed pain and swelling in his left groin and had been diagnosed with left-sided varicocele. For one week, he began developing left-sided abdominal pain and decreased urination frequency, so he came to our emergency department for evaluation. His physical examination revealed a hard mass occupying the entire left side of his abdomen, crossing the midline, and extending to the pelvic brim. His blood tests showed acute kidney injury and mild anemia. Computed tomography of his abdomen showed a large retroperitoneal mass on the left side, displacing the left kidney inferiorly and the spleen superiorly with thoracic epidural compression. Thrombus was also identified in his left renal vein and inferior vena cava. Computed tomography of his chest showed bilateral pulmonary nodules. A computed tomography-guided abdominal mass biopsy was performed, and the diagnosis of adrenocortical carcinoma was made on the basis of pathology and immunohistochemistry. His hormonal evaluations were normal. His kidney

    Full Text Available CONTEXT: Portal vein thrombosis refers to a total or partial obstruction of the blood flow in this vein due to a thrombus formation. It is an important cause of portal hypertension in the pediatric age group with high morbidity rates due to its main complication - the upper gastrointestinal bleeding. OBJECTIVE: To describe a group of patients with portal vein thrombosis without associated hepatic disease of the Pediatric Hepatology Clinic of the Hospital das Clínicas, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil with emphasis on diagnosis, presentation form and clinical complications, and the treatment of portal hypertension. METHODS: This is a descriptive study of a series of children and adolescents cases assisted from January 1990 to December 2010. The portal vein thrombosis diagnosis was established by ultrasound. RESULTS: Of the 55 studied patients, 30 (54.5% were male. In 29 patients (52.7%, none of the risk factors for portal vein thrombosis was observed. The predominant form of presentation was the upper gastrointestinal bleeding (52.7%. In 20 patients (36.4%, the initial manifestation was splenomegaly. During the whole following period of the study, 39 patients (70.9% showed at least one episode of upper gastrointestinal bleeding. The mean age of patients in the first episode was 4.6 ± 3.4 years old. The endoscopic procedure carried out in the urgency or electively for search of esophageal varices showed its presence in 84.9% of the evaluated patients. The prophylactic endoscopic treatment was performed with endoscopic band ligation of varices in 31.3% of patients. Only one died due to refractory bleeding. CONCLUSIONS: The portal vein thrombosis is one of the most important causes of upper gastrointestinal bleeding in children. In all non febrile children with splenomegaly and/or hematemesis and without hepatomegaly and with normal hepatic function tests, it should be suspect of portal vein thrombosis. Thus, an

    This case report is about a 70-years-old female patient, suffering from discal hernia, with compression of the iliac vein, that led to the formation of deep vein thrombosis of the lower limbs. The angio-CT scan revealed the starting point of the L4- L5 compression where a voluminous discal hernia caused deep vein thrombosis, with the involvement the femoro-popliteal venous axis. Blood samples and PET-CT scans excluded other possible etiologic factors. This case demonstrates how a voluminous discal hernia can cause venous thrombosis.

    Full Text Available Abstract Introduction Gastric variceal bleeding due to splenic vein thrombosis is a life-threatening situation and is often difficult to manage by endoscopy. In the worst cases, an emergency splenectomy may be required to stop variceal bleeding. Case presentation We report the case of a 60-year-old Caucasian woman with bleeding gastric varices secondary to splenic vein thrombosis treated by splenic artery embolization. Successful embolization was performed by depositing coils into the splenic artery resulting in cessation of variceal bleeding. After embolization there was no recurrence of bleeding. Conclusion Splenic artery embolization can be an effective and definite treatment for variceal bleeding secondary to splenic vein thrombosis.

    Full Text Available CONTEXT: There are no reports in the literature of massive deep venous thrombosis (DVT associated with cisplatin, bleomycin and etoposide (BEP cancer treatment. CASE REPORT: The patient was a 18-year-old adolescent with a nonseminomatous germ cell tumor of the right testicle, with the presence of pulmonary, liver, and massive retroperitoneal metastases. Following radical orchiectomy, the patient started chemotherapy according to the BEP protocol (without routine prophylaxis for DVT. On day 4 of the first cycle, massive DVT was diagnosed, extending from both popliteal veins up to the thoracic segment of the inferior vena cava. Thrombolytic therapy with streptokinase was immediately started. On day 2 of thrombolytic therapy, the patient developed acute renal failure, due to extension of the thrombosis to the renal veins. Streptokinase was continued for six days and the outcome was remarkably favorable.

    Rosenfeld, Hannah; Byard, Roger W

    2012-05-01

    Venous stasis predisposes to thrombosis. One hundred and sixty cases of fatal pulmonary thromboembolism were reviewed to determine how many cases had deep venous thromboses associated with venous blood flow reduction caused by external pressure from benign pelvic masses. 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.

    Full Text Available Abstract Introduction Renal vein thrombosis, although rare in adults, is well recognized in neonates and is one of the most common manifestations of neonatal thromboembolic events. The etiology of renal vein thrombosis remains unidentified in the majority of cases. We report a case of renal vein thrombosis in a neonate associated with elevated maternal lipoprotein (a. Case presentation A full-term female infant, appropriate for gestational age, was born via spontaneous vaginal delivery to an 18-year-old primigravida. The infant's birth weight was 3680 g and the Apgar scores were eight and nine at 1 and 5 minutes respectively. Evaluation of the infant in the newborn nursery revealed a palpable mass in the right lumbar area. Tests revealed hematuria and a high serum creatinine level of 1.5 mg/dl. An abdominal ultrasound Doppler flow study demonstrated an enlarged right kidney, right renal vein thrombosis, and progression of the thrombosis to the inferior vena cava. There was no evidence of saggital sinus thrombosis. An extensive work-up of parents for hypercoagulable conditions was remarkable for a higher plasma lipoprotein (a level of 73 mg/dl and an elevated fibrinogen level of 512 mg/dl in the mother. All paternal levels were normal. The plasma lipoprotein (a level in the neonate was also normal. The neonate was treated with low molecular weight heparin (enoxaparin at 1.5 mg/kg/day every 12 hours for 2 months, at which time a follow-up ultrasound Doppler flow study showed resolution of the thrombosis in both the renal vein and the inferior vena cava. Conclusion There have been no studies to date that have explored the effect of abnormal maternal risk factors on fetal hemostasis. A case-control study is required to investigate whether elevated levels of maternal lipoprotein (a may be a risk factor for neonatal thrombotic processes. Although infants with this presentation are typically treated with anticoagulation, there is a lack of evidence

    Renal vein thrombosis (RVT) is the most common noncatheter-related thrombosis encountered in infancy, most of which occurs in neonates. The optimal management strategy for neonatal RVT is unclear. Fibrinolytic and heparin therapy may play a role in preventing chronic renal failure in neonates with bilateral RVT. However, the use of fibrinolytics early after any major surgery requires tremendous caution. In this report, we describe the successful use of fibrinolysis in a neonate with bilateral RVT after repair of truncus arteriosus in the early postoperative period.

    Antiphospholipid syndrome is a multisystem auto-immune disorder characterized by thrombotic events and the presence of circulating antiphospholipid antibodies. Large vessel involvement in the form of thrombosis/stenosis and thrombotic microangiopathy is a commonly described renal finding. However, non-thrombotic glomerulopathies are increasingly being recognized in patients with antiphospholipid syndrome. We report a rare occurrence of both renal vein thrombosis and membranous nephropathy in a previously healthy adolescent male. Investigations revealed persistently positive antiphospholipid antibodies in the absence of an underlying systemic autoimmune disorder or malignancy. Our patient responded favourably to anti-proteinuric therapy and anticoagulation with complete resolution of proteinuria and a nearly occlusive thrombus.

    Purpose: Intrahepatic thrombus is usually associated with either cirrhosis or hepatocellular carcinoma (HCC). Most HCCs enhance after the administration of MnDPDP (Teslascan). Our objective was to analyze the enhancement characteristics of tumour portal vein thrombi. Material and Methods: Thrombi affecting the main or segmental portal veins (17 cases) and the suprahepatic inferior vena cava (1 case) were retrospectively selected from a series of 128 patients studied with MR imaging before and after the administration of MnDPDP. Enhancement was assessed qualitatively and quantitatively. Results: All tumour thrombi enhanced after MnDPDP administration. The enhancement was more conspicuous in the GRE images. On the quantitative evaluation, the portal thrombus enhancement was greater for GRE images than SE images. Portal thrombi enhanced more than the liver and the HCCs. There was a significant difference between the enhancement of the HCCs and the thrombi with both MR imaging techniques. (orig./AJ).

    Full Text Available Abstract Background Pancreatic metastases from previously treated renal cell carcinoma are uncommon. Surgical resection of pancreatic metastasis remains the only worthwhile modality of treatment. Case presentation A case where pancreatic metastasis from previously resected right sided renal cell carcinoma was resected with a subtotal left pancreatectomy is described. An unusual feature was the presence of a large splenic vein tumor thrombus extending into the portal vein with associated portal hypertension. The patient underwent an uneventful portal vein resection with primary anastomosis. Conclusion This is possibly the first documented case of portal vein renal tumor thrombosis in a case of isolated pancreatic metastasis from previously operated renal cell carcinoma in published world surgical literature.

    Renal cell carcinoma (RCC) is the most common renal malignancy in adults. Since complete surgical resection is the treatment of choice, accurate staging and extent delineation are imperative for optimal management. Owing to venous tropism, the tumour has a propensity to extend into renal vein and/or inferior vena cava. However, contiguous gonadal vein extension has rarely been reported. Here we present an unusual case of a 65-year-old woman who demonstrated a large left renal mass with extension of tumour thrombus into the left renal and ovarian veins with multiple retroperitoneal venous collaterals detected on multiphasic CT examination. This preoperative imaging information facilitated en bloc resection of the tumour and thrombosed vessels. To the best of our knowledge, this is the first case where comprehensive imaging evaluation enabled successful surgical management of RCC with malignant ovarian vein thrombosis and limited peroperative complications.

    Acute renal vein thrombosis (RVT) causes rapid deterioration of renal function if it is not treated aggressively. Conventional anticoagulation therapy is the standard mode of treatment; however, the need for rapid and complete resolution has led to the development of newer modes of treatment such as percutaneous catheter-directed techniques. We describe a case of acute RVT with deteriorating renal functions that highlights the rational of percutaneous catheter-directed combined pharmacomechanical thrombolysis-thrombectomy approach to successfully restore the renal vein patency with improvement of the renal function.

    Oral combined contraceptive pill (OCCP) is popular as birth control pills. Like all other drugs, they are not free from risks. Women taking certain types of OCCP have higher risk of developing deep vein thrombosis (DVT). A 29 year old married woman had taken OCCP for 3.5 months, developed deep vein thrombosis of left leg. Hereditary and acquired causes of DVT were excluded. She was treated with parenteral and oral anticoagulants simultaneously and was advised to discontinue OCCP. Initially the risk of blood clot was believed to be due to dose of estrogen but recent study relates it to the type of progesterone involved in OCCP. Thus, it is still a matter of debate, whether to associate risk of DVT to the amount of estrogen alone or also to the type of progestin. Apart from careful selection of patients, one should also look for the risk of venous thromboembolism irrespective of type of OCCP prescribed.

    The purpose of this study was to characterize differences in the prevalence of hereditary and acquired thrombophilia in patients with splanchnic vein thrombosis (SVT). A total of 88 consecutive patients with SVT, including Budd Chiari Syndrome (n = 47) and portal extrahepatic portal vein obstruction (n = 41), underwent comprehensive thrombophilia testing, including testing for heritable and acquired causes. In 33 (37.5%) patients, etiology could be explained by at least 1 of the heritable etiologic factors, and 31 (35.2%) patients could be explained by at least 1 of the acquired causes studied. The combination of multiple concurrent factors was present in 9 (11.4%) patients. Among the heritable causes, the risk of SVT was found increased in the presence of thrombophilia resulting from the deficiencies of the naturally occurring anticoagulant proteins, and the acquired thrombogenic factors were significantly associated with causation of thrombosis in adult patients with SVT.

    Deep venous thrombosis as a result of venous wall injury provoked by trauma is a common finding. It often occurs in patients with sportive overstraining, caused by over fatigue of the body structures. In 2007, the entity of "acute wiiitis" was first described in a letter to the New England Journal of Medicine. Acute wiiitis sums up all affections, mainly skeletal and muscle affections, provoked by playing Nintendo Wii, a very common and loved video-game system. Deep venous thrombosis as a consequence of Nintendo Wii has not been described so far. We present a patient with a massive free floating thrombus of the left pelvic veins originating from the gluteal veins and reaching into the inferior vena cava after playing Nintendo Wii.

    2003-01-01

    Objective To study thrombosis and its significance after acute experimental pulmonary thromboembolism. Methods The acute pulmonary thromboembolism (PTE) model of rabbits was established by intravenous injection of autologous blood clots (0.04 g/kg) which were stabilized in temperature-controlled (70℃) distilled water for 10 min. The process of thrombosis was observed grossly and microscopically. The Quick's method was used to examine the coagulability of blood and radioimmunoassay was employed to measure the level of plasma thromboxane A2 and endothelin. Results Thrombotic propensity was observed at 1 h, fresh thrombus started to form and the blood coagulation system was activated at 24 h following clots infusion. Emboli were completely or partly dissolved at 5 d and appeared to organize at both 10 d and 14 d after clots were infused. Venous plasma thromboxane A2 concentration began to increase at 5 min (2489.59±714.68 ng/L) and reached its maximum at 15 min (2545.46±590.58 ng/L) then declined at 60 min after clot infusion (P<0.001, respectively, vs 626.59±510.02 ng/L of pre-clot). The level of endothelin in both arterial and venous blood increased at 5 d post-clot infusion (840.74±154.19 ng/L, 230.35±52.39 ng/L, respectively) compared to the one before infusion (602.66±453.26 ng/L, 148.01±53.28 ng/L, respectively, P<0.05).Conclusions Thrombosis occurs after autologous-blood-clot-induced PTE. The interactions between thrombus formation, fibrinolysis and organization determines the consequences of emboli. Abnormalities of endothelin metabolism and the increment of thromboxane A2 may play an important role in PTE.

  11. EVALUATION OF AVERAGE DIAMETER OF LOWER EXTREMITY VEINS IN ACUTE AND CHRONIC THROMBOSIS AND COMPARISON WITH NORMAL PERSONS BY DOPPLER SONOGRAPHY

    Full Text Available The goal of this study was to define the normal range of diameter in the deep vein of the lower limb and to compare this range with diameter of the veins with acute thrombosis and of veins with chronic thrombosis by using color doppler sonography. The study was cross sectional. The vein diameter and vein to artery ratio in different levels were measured and the following results were obtained. In patients with acute thrombosis the vein diameter and vein to artery ratio were more than normal range and this difference had statistical significance so we can reliably predict acute thrombosis if the vein diameter is upper than a suggested level. In chronic thrombosis, however, the vein diameter is not a good diagnostic factor and so we can not rely on it.

    A 37-year-old woman was admitted to hospital with severe tonsillitis with unilateral necrotizing tonsillitis. She suddenly got fever, malaise, difficulties swallowing, pain in the throat and deterioration despite four days of penicillin treatment. During hospitalisation, she experienced abdominal pain, and blood tests showed pancytopenia. She was transferred to a haematological department, where a bone marrow biopsy showed acute myeloid leukaemia. Subsequently, an abdominal computed tomography with intravenous contrast revealed bilateral renal vein thrombosis, probably because of coagulopathy due to leukaemia.

    Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but might also occur in absence of an overt liver disease. Several causes, either local or systemic, might play an important role in PVT pathogenesis. Frequently, more than one risk factor could be identified; however, occasionally no single factor is discernable. Clinical examination, laboratory investigations, and imaging are helpful to provide a quick diagnosis, as prompt treatment might greatly affect a pa...

    Splenic vein thrombosis can lead to gastric varices. Subsequent upper gastrointestinal bleeding may ensue related to the change in venous outflow to the portal system. Vascular surgeons are infrequently asked to assist in the management of this entity. However, with many vascular surgeons providing diverse endovascular-based interventions, understanding catheter-based solutions is imperative. This report presents a case in which arterial embolization was used to treat gastric variceal bleeding.

    Peripherally inserted central venous catheters (PICCs) are widely used in cancer patients. Although PICC is a convenient tool, its use is associated with an obvious increase in the incidence of venous thrombosis. The risk factors for deep vein thrombosis associated with the use of PICCs in cancer patients are largely unexplored. This study aimed to investigate the incidence of PICC-associated thrombosis in lymphoma compared with its incidences in other types of cancer. A total of 8028 adult cancer patients inserted with PICC between June 2007 and June 2015 were included in this study. A total of 249 of the 8028 included patients (3.1%) inserted with PICC developed upper extremity deep vein thrombosis (PICC-UEDVT). Patients with lymphoma were more likely to have PICC-UEDVT than those with other types of malignancies (7.1% vs. 2.80%; P < 0.001). Logistic analysis revealed that a lymphoma diagnosis was a risk factor for UEDVT in cancer patients inserted with PICC (OR: 3.849, 95% CI: 2.334–6.347). Patients with lymphoma may be more predisposed to developing PICC-UEDVT than those with other types of malignancies. Identifying the mechanism underlying the relationship between PICC-UEDVT and lymphoma requires further study. PMID:27078849

    Indications for thrombectomy in acute thrombosis of the deep veins of the pelvis and lower extremities are: 1. Phlegmasia coerulea dolens with imminent danger of venous gangrene. 2. All cases: a) with contraindications for a therapy with fibrinolysis, b) after therapy-failures with thrombolytic therapy, c) thrombosis of more than 3 days duration. 3. In cases associated with tumours or trauma. If a thrombectomy can only be partially achieved, or in cases with an old thrombosis, a temporary arteriovenous fistula is performed. In cases with phlegmasia alba and the inexistence of danger for an extremity treatment with fibrinolysis, this is preferable in the first three days after onset, if general conditions permit this treatment. Results of venous thrombectomies are particularly astonishingly good in phlegmasia coerulea and it is therefore mandatory to transfer all fresh cases of thrombosis of the deep veins of the peelvis and lower extremities to an angiologic center in order to differentiate cases for fibrinolytic therapy, from those which require surgical intervention.

    The stated aims of treating acute deep vein thrombosis (DVT) are to prevent a pulmonary embolism, stop the clot from spreading, reduce the risk of a recurrence; they are less concerned with the late morbidity associated with post-thrombotic syndrome (PTS). In accordance with the French (Afssaps, 2009) and North American (ACCP, 2008) recommendations, anticoagulants (LMWH, heparin, AVK) form the cornerstone for treating DVT. These treatments appear to be far less effective in preventing post-thrombotic syndrome (PTS), associated with venous hypertension, residual occlusion, and with reflux caused by valve incompetence. Given that, the new aim is to optimise the prevention of PTS, the ACCP guidelines, unlike those of Afssaps, "suggest" for selected patients suffering from acute iliofemoral DVT, the use of both classic anticoagulants, and in situ percutaneous administration of thrombolytic drugs (recommendation grade 2B) and simultaneous correction of any underlying anatomical anomalies using angioplasty and stenting (recommendation 2C). Contemporary endovascular methods, referred to collectively as "facilitated" thrombolysis, combine low doses of rtPa or Urokinase administered locally, and the removal of the clot using various mechanical, rotating, rheolytic systems, or using ultrasound. The results of non-randomised, heterogeneous studies objectivised a lysis rate of 80%, a 50% lower risk of haemorrhage complications compared with systemic thrombolysis (<4%), and a clear reduction in treatment time (one-shot methods possible for procedures lasting less than 2 hours). This data ties in with the modern "open vein" concept which underpins the hope of an improvement in the late prognosis of acute DVT, through the removal of a clot, thereby improving permeability and valve integrity; this hypothesis is supported by the results at 24 months of a randomised CaVent objectifying absolute risk reduction of 15% in the thrombolysis in situ. The current randomised study (ATTRACT

    Full Text Available Septic thrombosis of the internal jugular vein or Lemierre’s syndrome is a rare form of metastatic septic thromboembolitis, typically involving superinfection with Fusobacterium Necrophorum, internal jugular vein thrombosis and remote septic emboli.CASE REPORT: A 49-year-old male was referred for a painful cervicofacial swelling on the left, obliteration of the buccal sulcus, as well as swelling of both the soft and hard palate and the floor of the mouth ipsilaterally, accompanied by severe trismus and difficulty in swallowing. The patient underwent intraoral and extraoral incisions and drainage of the affected anatomical spaces and tracheotomy. The patient’s clinical condition was steadily improving; following examination with CT scan,9 days post-op, internal jugular vein thrombosis was diagnosed. The patient was put on anticoagulants. The postoperative course continued uneventfully, and the patient was discharged. One month post-operatively the vessel was normal and anticoagulant treatment was discontinued.CONCLUSION: Since Lemierre’s syndrome is not only rare but also tends to be underdiagnosed when there is no obvious cause of sepsis, it should be included in the differential diagnosis if the patient’s general contition deteriorates in spite of the treatment.

    The present work was aimed at studying the state of the inferior vena cava system according to the findings of duplex scanning in dynamics of acute cerebral circulation impairments (ACCI). Amongst 100 patients with ACCI, lower limb vein deep thrombosis (LLVDT) was revealed in 57% of cases. The incidence of LLVDT in patients with intracerebral haemorrhage was higher than in those with ischaemic stroke, however there were no statistically significant differences between the type of ACCI (p=0.06) and subtypes of ischaemic stroke (atherothrombotic, ceardioembolic) (p = 0.68). The main risk factors for LLVDT are the presence of pronounced motion deficit in the extremities, induced by the underlying disease (p=0.02) and immobilization. In the overwhelming majority of patients (81%) thrombosis localized isolatedly in the crural veins. Ascending thrombosis and the development of a floating thrombus were represented mainly on the side of motility deficit in the extremities. We have confirmed a strong association between positive dynamics in the neurological status of patients and frequency of recanalization of thrombi (p=0.043). Ultrasonographic examination of lower limb veins in dynamics of ACCI is an important component of preventive and therapeutic process.

    Snakebite is a health issue specific to some parts of the world, especially in the tropical areas, where it produces many victims. The main clinical damage caused by snakebite involves haemotoxic, neurotoxic and myotoxic reactions. We report the case of a young woman suffering from snakebite who developed deep vein thrombosis and compartment syndrome. We present the case of a 32-year-old Romanian woman who was injured by her own Crotalinae snake (also known as pit viper or rattlesnake) on her left forearm. When admitted to our Emergency Department, she was conscious with a Glasgow coma scale of 12/15, somnolent, febrile, suffering of headache, tachypnoea; the marks of the snakebite were located in the distal part of the anterior left forearm; she had pain and bleeding at the bite site and swelling of the left upper limb with lymphangitis up to the axilla. She experienced fasciotomy-requiring compartment syndrome of the upper limb and required unfractionated heparin and close monitoring using activated partial thromboplastin time evolution due to micro-thrombosis in the brachial vein. Local improvement was achieved in the next 4 days with progressive diminishment of local tenderness and swelling. Limb deep vein thrombosis might be induced by snakebite, despite the pro-haemorrhagic general condition induced by the envenomation. A high index of clinical suspicion is needed for early diagnosis and timely management, which can improve survival of these patients.

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

    The purpose of current study is to evaluate the response of the patients with portal vein thrombosis (PVT) or hepatic vein thrombosis (HVT) in hepatocellular carcinoma (HCC) treated with three-dimensional conformal radiation therapy (3D-CRT). In addition, survival of patients and potential prognostic factors of the survival was evaluated. Forty-seven patients with PVT or HVT in HCC, referred to our department for radiotherapy, were retrospectively reviewed. For 3D-CRT plans, a gross tumor volume (GTV) was defined as a hypodense filling defect area in the portal vein (PV) or hepatic vein (HV). Survival of patients, and response to radiation therapy (RT) were analyzed. Potential prognostic factors for survival and response to RT were evaluated. The median survival time of 47 patients was 8 months, with 1-year survival rate of 15% and response rate of 40%. Changes in Child-Pugh score, response to RT, Eastern cooperative oncology group performance status (ECOG PS), hepatitis C antibody (HCVAb) positivity, and additional post RT treatment were statistically significant prognostic factors for survival in univariate analysis (p = 0.000, p = 0.018, p = 0.000, p = 0.013, and p = 0.047, respectively). Of these factors, changes in Child-Pugh score, and response to RT were significant for patients' prognosis in multivariate analysis (p = 0.001 and p = 0.035, respectively). RT could constitute a reasonable treatment option for patients with PVT or HVT in HCC with acceptable toxicity. Changes in Child-Pugh score, and response to RT were statistically significant factors of survival of patients.

    Full Text Available Levoatriocardinal vein (LACV is characterized by an abnormal connection between pulmonary and systemic venous return. This extremely rare cardiac malformation is usually associated with left-sided obstructive lesions including mitral atresia, hypoplastic left-heart syndrome, and abnormal pulmonary venous connection. Patients may have low systemic cardiac output and pulmonary venous obstruction symptoms. In this manuscript, we report a case with LACV and normal pulmonary venous return with absence of any intracardiac pathology. LACV was demonstrated with echocardiography, angiography, and computed tomography. Surgical correction was made successfully.

    Nephrotic syndrome causes a hypercoagulable state, leading to both venous and arterial thrombosis. The mechanisms are as yet unclear, but numerous alterations in coagulant and anti-coagulant factors have been reported [Llach et al. 1985, Harris and Ismail 1994]. The most common clinical features in adults are renal vein thrombosis, femoral vein thrombosis and pulmonary embolism, although thrombosis in numerous other arterial and venous sites has been described [Cameron 1984, Llach et al. 1985]. Intracranial thrombosis is rare, although in adult nephrotic syndrome arterial thrombosis is well recognized [Fuh et al. 1991]. We report a patient with minimal change nephrotic syndrome who developed venous sinus thrombosis detected by magnetic resonance (MR) scanning.

    Agenesis of the inferior vena cava, especially of the infrarenal segment, is exceptional. This condition is thought to result from thrombosis during gestation rather than from a true congenital malformation. Agenesis of the inferior vena cava can be associated with renal vein thrombosis, which in turn is related to suprarenal hemorrhage in the fetus. We present a case of agenesis of the inferior vena cava with preservation of the hepatic segment, thrombosis of the left renal vein, and secondary bilateral suprarenal hemorrhage diagnosed prenatally using sonography and magnetic resonance imaging.

    Background: Deep vein thrombosis is an important cause of morbidity and mortality. However, its association with adenomatous polyposis coli is extremely rare. Here we present an interesting case of deep vein thrombosis associated with adenomatous polyposis coli. Case Presentation: A 15 year old female who was having fever and diarrhea for 5 months developed bilateral asymmetric painful swelling of lower limbs for 1 month. Doppler ultrasound of lower limbs revealed presence of thrombosis from inferior vena cava up to popliteal vein. Colonoscopy and biopsy were suggestive of adenomatous polyposis coli. However, she could not tolerate anticoagulant therapy and was put on aspirin therapy for 6 months to which she responded well with the resolution of thrombus. Conclusion: Role of aspirin therapy may be considered whenever a patient of venous thrombosis cannot tolerate anticoagulant therapy. PMID:27386068

    Background Differential diagnosis of isolated calf muscle vein thrombosis (ICMVT) and gastrocnemius hematoma is essential for early identification of deep vein thrombosis (DVT).This study aimed to investigate the diagnostic value of high-frequency color Doppler ultrasound for differential diagnosis of ICMVT and gastrocnemius hematoma.Methods A retrospective case series of 35 ICMVT (M∶F,21∶14; mean age (64.5±10.6) years) and 23 gastrocnemius hematoma (M∶F,16∶7; mean age (75.4±11.8) years) patients with bilateral/unilateral lower limb pain was conducted between January 2006 and September 2012.Characteristics and the morphology of high-frequency color Doppler ultrasonography of the lower limb deep vein,great saphenous vein,calf muscles,skin,and soft tissue were examined.Results ICMVT hypoechoic signals were characterized by long,tube-like masses on longitudinal sections and oval masses on transverse sections,with apparent muscle thrombosis boundaries,distal and proximal venous connections,and,often,lower limb DVT.Gastrocnemius hematoma hypoechoic signals were characterized by large volumes,enhanced posterior hematoma echo,hyperechoic muscle boundaries,no hematoma blood flow,and no DVT,and clear differences in trauma/exercise-and oral anticoagulant-induced hematomas were readily apparent.According to the measurement,the ratio of long diameter/transverse diameter (D/T) in ICMVT patients was about less than 2.0,whereas in gastrocnemius hematoma patients the ratio was more than 2.0.Early stage isoechoic and hypoechoic signals were detected with gradually increasing ovular anechoic areas.Partial muscle fibers in the hematoma due to muscle fractures were apparent.Conclusion High-frequency color Doppler ultrasound was found to be a sensitive and reliable method for differential diagnosis of ICMVT and gastrocnemius hematoma due to trauma and exercise or prolonged oral anticoagulant use.

    A73 -year-old man underwent a sigmoidectomy for sigmoid colon cancer with liver metastasis. After the operation, he received CapeOX combined with bevacizumab therapy. After 6 courses, the liver metastasis was undetectable on computed tomography scans. After 15 courses, computed tomography revealed ascites, and chemotherapy was discontinued. Two months later, computed tomography revealed portal vein thrombosis. Owing to the chronic nature of the thrombosis, thrombolytic therapy was not initiated. However, preservation therapy using antiplatelet drugs for 1 month resolved the ascites and the thrombosis. The risk of serious thrombosis must be considered when using bevacizumab.

    Gastric varices (GV) are one of the most common complications for patients with portal hypertension. Currently, histoacryl injection is recommended as the initial treatment for bleeding of GV, and this injection has been confirmed to be highly effective for most patients in many studies. However, this treatment might be ineffective for some types of GV, such as splenic vein thrombosis-related localized portal hypertension (also called left-sided, sinistral, or regional portal hypertension). Herein, we report a case of repeated pancreatitis-induced complete splenic vein thrombosis that led to intractable gastric variceal bleeding, which was treated by splenectomy. We present detailed radiological and pathological data and blood rheology analysis (the splenic artery - after a short gastric vein or stomach vein - gastric coronary vein - portal vein). The pathophysiology can be explained by the abnormal direction of blood flow in this patient. To our knowledge, this is the first reported case for which detailed pathology and blood rheology data are available.

    Full Text Available Abstract Background Splanchnic vein thrombosis may complicate inherited thrombotic disorders. Acute cytomegalovirus infection is a rare cause of acquired venous thrombosis in the portal or mesenteric territory, but has never been described extending into a main hepatic vein. Case presentation A 36-year-old immunocompetent woman presented with acute primary cytomegalovirus infection in association with extensive thrombosis in the portal and splenic vein. In addition, a fresh thrombus was evident in the right hepatic vein. A thorough evaluation for a hypercoagulable state was negative. The clinical course, biological evolution, radiological and histological findings were consistent with cytomegalovirus hepatitis complicated by a partial acute Budd-Chiari syndrome and portal thrombosis. Therapeutic anticoagulation was associated with a slow clinical improvement and partial vascular recanalization. Conclusion We described in details a new association between cytomegalovirus infection and acute venous thrombosis both in the portal vein and in the right hepatic vein, realizing a partial Budd-Chiari syndrome. One should be aware that this rare thrombotic event may be complicated by partial venous outflow block.

  20. 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

    Objective:To study the expression changes of matrix metal loproteinases (MMPs) in traumatic deep vein thrombosis (TDVT) in a rat model with the aid of gene chip technology and to explore the roles of MMPs in TDVT.Methods:Totally 150 Sprague Dawley rats were randomly divided into control group (n=10) and model group (n=140). Rat models of TDVT were established by clamping the femoral vein and fixing the bilateral hind limbs. Then fixation of the hip spica with plaster bandage was conducted.According to the observation phases and/or biological situations of the femoral vein thrombosis, the model rats were further divided into 7 groups. Vascular tissues were obtained from each group through noninvasive incision into the femoral vein at corresponding time points. We adopted the Trizoi one-step method for total RNA extraction,Affymetrix RAT 230 2.0 array for detection of RNA expressions and fold change (FC) analysis for changes of differential expressions of MMPs in each group. The main outcome parameters measured included expressions of MMP-2,MMP-3, MMP-7, MMP-8, MMP-9, MMP-10, MMP-11,MMP- 12, MMP-13, MMP- 14, MMP- 16, MMP-23 and MMP-24. Gene array data of these MMPs were analyzed by the Affymetrix Microarray Analysis software (Version 5.0).Results:FC analysis showed differential expressions of MMPs in each group during the course of TDVT. At the initial period of thrombosis, MMP-2, MMP-3, MMP-7,MMP-8, MMP-9, MMP- 10, MMP-11, and MMP-24 had significantly high expression, while MMP-12, MMP-13,MMP-14, MMP-16 and MMP-23 had relatively low expression. MMPs were all highly expressed at the peak time of thrombosis. In the process of thrombus resolution,MMP-2, MMP-10, MMP-16 and MMP-24 have relatively low expression, while MMP-12, MMP-13, MMP-14,MMP-16 and MMP-23 have significantly high expression.Conclusion:MMPs may affect the process of TDVT through transcription regulation of the fibrinolysis-anti-fibrinolytic system during the course of thrombosis and thrombus resolution.

    Full Text Available Maxim E Shaydakov, Jose A Diaz Department of Surgery, Section of Vascular Surgery, Conrad Jobst Vascular Research Laboratories, School of Medicine, University of Michigan, MI, USA Abstract: Venous thromboembolism is a serious medical, social, and economic problem. A number of treatment options exist to decrease mortality and morbidity in patients with deep vein thrombosis (DVT. An accurate and timely diagnosis of this condition is important to improve immediate and long-term prognosis. The standard diagnostic algorithm implying assessment of the clinical probability of the disease, d-dimer test, and venous duplex ultrasound is not optimal. Infrared thermography is a relatively new diagnostic modality under clinical investigation for various medical conditions. This study aims to review the published evidence on infrared thermography as a possible alternative tool in DVT diagnosis. The authors conclude that infrared thermography is still an experimental diagnostic tool for patients with DVT, and requires more clinical research evidence to support theoretical advantages and suggest a possible clinical application.

    To evaluate the feasibility and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in patients with active variceal bleeding due to liver cirrhosis and pre-existing portal vein thrombosis. Of a total of 123 patients who underwent TIPS, 14 patients with intractable variceal bleeding due to portal hypertension and portal vein thrombosis were included in this study. Noncavernomatous portal vein occlusion was seen in eight patients, and complete portal vein occlusion with cavernomatous trans-formation in six. For all patients, the methods used for TIPS placement were the same as those used in patients with patents portal veins. In seven of eight patients with noncavernomatous occlusion, right hepatic vein-right portal vein shunting was performed; in one with knoncavernomatous occlusion, a shunt was created between the right hepatic and left portal vein. In five of six patients with cavernomatous occlusion, the right hepatic and main portal vein were connected via a collateral vein. The procedures were technically successful in all except one patient. Immediate hemostatis was achieved after all technically successful procedures, and no significant complications were encountered. Minor complications were noted in six patients (three biliary tree punctures, one transperitoneal puncture, one splenic vein perforation, one hepatic subcapsular hematoma). TIPS is a technically feasible and hemodynamically effective procedure, even in patients with active variceal bleeding due to cirrhosis and complete portal vein occlusion.

    Abstract Vascular involvement can be seen in up to 40% of patients with Behcet syndrome (BS), the lower-extremity vein thrombosis (LEVT) being the most common type. The aim of the current study was to compare venous Doppler findings and clinical features between BS patients with LEVT and control patients diagnosed as having LEVT due to other causes. All consecutive 78 patients (71 men, 7 women; mean age 38.6 ± 10.3 years) with LEVT due to BS and 50 control patients (29 men, 21 women; mean age 42.0 ± 12.5 years) who had LEVT due to other causes, or idiopathic, were studied with the help of a Doppler ultrasonography after a detailed clinical examination. Patterns of venous disease were identified by cluster analyses. Clinical features of chronic venous disease were assessed using 2 classification systems. Venous claudication was also assessed. Patients with BS were more likely to be men, had significantly earlier age of onset of thrombosis, and were treated mainly with immunosuppressives and less frequently with anticoagulants. Furthermore, they had significantly more bilateral involvement, less complete recanalization, and more frequent collateral formation. While control patients had a disorganized pattern of venous involvement, BS patients had a contiguous and symmetric pattern, involving all deep and superficial veins of the lower extremities, with less affinity for crural veins. Clinical assessment, as measured by the 2 classification systems, also indicated a more severe disease among the BS patients. In line, 51% of the BS patients suffered from severe post-thrombotic syndrome (PTS) and 32% from venous claudication, whereas these were present in 8% and 12%, respectively, among the controls. Among BS patients, a longer duration of thrombosis, bilateral femoral vein involvement, and using no anticoagulation along with immunosuppressive treatment when first diagnosed were found to be associated independently with severe PTS.

    Full Text Available The patient was a male in his 70s with a history of chronic renal failure and dilated cardiomyopathy. In January 2011, he underwent abdominoperineal resection of the rectum, right hepatic lobectomy, and resection of a portal vein tumor thrombus with a diagnosis of rectal cancer and metastatic liver cancer accompanied by portal vein tumor thrombosis. Although 5-fluorouracil + l-leucovorin therapy (RPMI regimen was carried out as postoperative adjuvant chemotherapy, the tumor marker (CEA and VA19-9 levels increased 8 months after surgery. Since the functions of major organs were impaired, UFT® + UZEL® therapy was started. The tumor marker levels decreased temporarily, but increased again 12 months after surgery, and so intravenous instillation of panitumumab was initiated. Nine administrations have been performed to date, with no increase in tumor marker levels or exacerbation of the condition. Also, no grade 2 or severer adverse event has been noted according to CTCAE v.4.0. The experience with this patient suggests the possibility that exacerbation of the condition of patients with liver metastasis of colorectal cancer accompanied by portal vein tumor thrombosis with abnormalities in the functions of major organs can be controlled temporarily by the administration of panitumumab alone.

    An estimated 300 million people worldwide suffer fromchronic hepatitis C with a prevalence of 0.8%-1.0% of the general population in Canada. An increasing pool of evidence exists supporting the use of pegylatedinterferon (pegIFN) and ribavirin combination therapy for hepatitis C. We report a 49-year old male of North American aboriginal descent with chronic hepatitis C (genotype 2b). Biopsy confirmed that he had cirrhosis with a 2-wk history of left eye pain and decreased visual acuity. He developed retinal vein thrombosis after 16 of 24 wk of pegIFN-α 2a and ribavirin combination therapy. He was urgently referred to a retinal specialist and diagnosed with non-ischemic central retinal vein occlusion of the left eye. PegIFN and ribavirin combination therapy was discontinued and HCV RNA was undetectable after 16 wk of treatment. Hematologic investigations revealed that the patient was a factor V Leiden heterozygote with mildly decreased protein C activity. Our patient had a number of hypercoagulable risk factors, including factor V Leiden heterozygosity, cirrhosis, and hepatitis C that alone would have most likely remained clinically silent. We speculate that in the setting of pegIFN treatment, these risk factors may coalesce and cause the retinal vein thrombosis.

    To evaluate the usefulness of ultrasonography for diagnosis of portal vein thrombosis (PVT) associated with the umbilical venous catheterization (UVC). We reviewed the abnormal ultrasonography of 54 patients with UVC. We observed echogenic thrombus in the portal vein by ultrasonography which has a 5-10 MHz linear transducer. We evaluated the frequency of PVT, the relationship between PVT and duration of UVC, and the location of catheter tip (Group I (n=41): above the diaphragm, Group II (n=9): between the diaphragm and the liver, Group III (n=4): below the liver), the location of thrombus on US, and the change of PVT on the follow-up ultrasonography. PVT was identified in the 7 neonates (13%) among the 54 neonates with UVC. The frequency of PVT was 5% on group I, 45% on group II and 25% on group III. The 6 cases among the 7 cases(86%) of PVT were localized to the umbilical portion of the left portal vein, and there were completely resolved (n=4) or regressed (n=1) on the follow-up ultrasonography(n=5). Remaining one case of PVT was located in the right, left, and main portal veins with collateral formation, and cavernous transformation occurred on the follow-up. Most PVTs by UVC are localized to the umbilical portion of left portal vein. Ultrasonography is a useful modality to diagnose PVT by UVC.

  9. Management of Anticoagulation for Portal Vein Thrombosis in Individuals with Cirrhosis: A Systematic Review

    2012-01-01

    Full Text Available Non-neoplastic portal vein thrombosis (PVT is an increasingly recognized complication of liver cirrhosis. It is often diagnosed fortuitously and can be either partial or complete. The clinical significance of PVT is not obvious except in some situations such as when patients are on the waiting list for liver transplantation. The only known therapy is anticoagulation which has been shown to permit the disappearance of thrombosis and to prevent further extension. Anticoagulation is a challenging therapy in individuals with liver cirrhosis because of the well-recognized coagulation abnormalities observed in that setting and because of the increased risk of bleeding, especially from gastrointestinal tract caused by portal hypertension. We herein review the current knowledge on that topic in order to highlight the advantages and disadvantages of the currently proposed therapeutic attitudes in face of the diagnosis of PVT in individuals with cirrhosis.

    Full Text Available Molecular targeted agents have lower hematological toxicity. However, specific side-effects such as allergic rashes, skin reactions and high cost limit their use. We report a case of 35-year-old male patient with carcinoma of left tonsil treated with concurrent cetuximab and radiotherapy. After four weeks of treatment, the patient developed sudden onset of pain in the left calf region radiating to the left foot. Doppler study of the left lower limb revealed complete thrombosis of superficial femoral, popliteal and proximal tibial arteries and veins and no flow in anterior tibial artery and lower posterior tibial artery. Emergency embolectomy was done. After 48 h of observation, no improvement was noted. A repeat Doppler examination showed similar finding. Ultimately a left lower limb amputation was done. We report simultaneous arterio-venous thrombosis associated with cetuximab-based chemoradiotherapy. Oncologists should be aware of this possible complication to undertake early intervention.

    Triathlon followers increase each year and long-distance events have seen major growth worldwide. In the cycling phase, athletes must maintain an aerodynamic posture on the bike for long periods of time. We report a case of a 38-year-old triathlete with symptoms of an axillary vein thrombosis 48h after a long triathlon competition. After 3days of hospitalization with a treatment consisted on enoxaparin anticoagulant and acenocumarol, the patient was discharged with instructions to continue treatment under home hospitalization with acetaminophen. Four weeks after the process, the patient was asymptomatic and the diameter of his arm was near normality. Due to the growing popularity of events based on endurance exercise, it is necessary more research to determine the etiopathogeny of deep venous thrombosis in athletes. Copyright © 2016 Elsevier Inc.

    The requirement for a safe diagnostic strategy of deep vein thrombosis (DVT) should be based on an overall objective post incidence of venous thromboembolism (VTE) of less than 1% during 3 mo follow-up. Compression ultrasonography (CUS) of the leg veins has a negative predictive value (NPV) of 97%-98% indicating the need of repeated CUS testing within one week. A negative ELISA VIDAS safely excludes DVT and VTE with a NPV between 99% and 100% at a low clinical score of zero. The combination of low clinical score and a less sensitive D-dimer test (Simplify) is not sensitive enough to exclude DVT and VTE in routine daily practice. From prospective clinical research studies it may be concluded that complete recanalization within 3 mo and no reflux is associated with a low or no risk of PTS obviating the need of MECS 6 mo after DVT. Partial and complete recanalization after 3 to more than 6 mo is usually complicated by reflux due to valve destruction and symptomatic PTS. Reflux seems to be a main determinant for PTS and DVT recurrence, the latter as a main contributing factor in worsening PTS. This hypothesis is supported by the relation between the persistent residual vein thrombosis (RVT = partial recanalization) and the risk of VTE recurrence in prospective studies. Absence of RVT at 3 mo post-DVT and no reflux is predicted to be associated with no recurrence of DVT (1.2%) during follow-up obviating the need of wearing medical elastic stockings and anticoagulation at 6 mo post-DVT. The presence or absence of RVT but with reflux at 3 to 6 mo post-DVT is associated with both symptomatic PTS and an increased risk of VTE recurrence in about one third in the post-DVT period after regular discontinuation of anticoagulant treatment. To test this hypothesis we designed a prospective DVT and postthrombotic syndrome (PTS) Bridging the Gap Study by addressing at least four unanswered questions in the treatment of DVT and PTS. Which DVT patient has a clear indication for long

    Full Text Available Deep venous thrombosis (DVT is not an uncommon condition in the intensive care unit (ICU, and having high morbidity and mortality. Upper limb DVT also is increasingly being recognized as a clinical entity. The presence of the indwelling catheter in neck veins is a risk for developing venous thrombus, which may be further aggravated by presence of thrombocytosis. In ICU patients with sepsis, reactive thrombocytosis has been found during the recovery phase. Here, we are presenting two cases, having thrombocytosis and central venous catheter who developed upper limb DVT.

    Massive splenic infarction and portal vein thrombosis (PVT) due to chronic myeloid leukemia (CML) is extremely rare. We describe 2 children who were presented with massive splenic infarction and PVT in the course of CML. Massive splenic infarction and PVT treated with splenectomy in one and with medical treatment in another in whom PVT resolved by cytoreductive treatment, led to downsizing of spleen or splenectomy. Splenic infarct and PVT should be considered in CML patients with long-lasting severe abdominal pain despite appropriate medical attempts. Splenectomy should be spared for persistent symptoms and complications.

    We present an 8-year-old boy who was referred to our center with the complaint of upper gastrointestinal bleeding and was diagnosed with hypersplenism and progressive esophageal varices. Performing a computerized tomography (CT) scan, we discovered a suspicious finding in the venography phase in favor of thrombosis in the splenic vein. Once complementary examinations were done and due to recurrent bleeding and band ligation failure, the patient underwent splenectomy. And during the one-year follow-up obvious improvement of the esophageal varices was observed in endoscopy.

    The incidence of deep vein thrombosis (DVT), diagnosed by ascending phlebography, was calculated in two Swedish districts. The average incidence per thousand population and year was 0.85 in males and 0.68 in females. Before the age of 50 the incidence was very low and almost the same in both sexes. After age 50 the incidence in men markedly increased with age. A similar increase was found in women, but not before age 60. DVT occurring after age 50 was significantly more common in men than in women. The study strongly suggests male sex as a risk factor for DVT.

    Full Text Available There are increasing number of deep vein thrombosis (DVT cases that are associated with the use of atypical antipsychotics. We are presenting a case report of a female patient who suffered from DVT. She was a known case of schizophrenia and was on risperidone 4 mg for the last 5 years. She had good physical health before that and there were no known risk factors for DVT. The family history of DVT was also found to be negative. She was managed by intravenous heparin followed by oral warfarin and amisulpride 100 mg/day. Atypical antipsychotics can induce DVT, and psychiatrist should be careful about it.

    Deep vein thrombosis is one of the common complications of orthopedic surgery. Studies indicated that genetic factors played a considerable role in the pathogenesis of deep vein thrombosis. Endothelial nitric oxide synthase which encoded by nitric oxide synthase 3 (NOS3), can generate nitric oxide in endothelial cells. As a predominant regulator for vascular homeostasis, nitric oxide might be involved in the pathogenesis of thrombosis. It had been proved that the NOS3 polymorphism (rs1799983) was associated with the development of cardiovascular diseases. Our objective was to evaluate the association between the NOS3 polymorphism (rs1799983) and deep vein thrombosis after orthopedic surgery in Chinese Han population. The polymorphism was genotyped in 224 subjects with deep vein thrombosis after orthopedic surgery and 580 controls. Allele and genotype frequencies were compared between subjects with deep vein thrombosis and control subjects. The allele and genotype frequencies of the NOS3 polymorphism (rs1799983) were significantly different between subjects with deep vein thrombosis and control subjects. There were also significant differences when the subjects were stratified by gender, surgery type and hypertension status. These findings suggested that the NOS3 polymorphism (rs1799983) was associated with susceptibility to the deep vein thrombosis after orthopedic surgery in Chinese Han population, and NOS3 might play a role in the development of deep vein thrombosis after orthopedic surgery.

    Deep vein thrombosis (DVT) always induced venous thrombosis. Most cases of venous thrombosis were induced by deep vein thrombosis (DVT), with high incidence rate of >60% in >60 years old people. Near-infrared spectroscopy (NIRS) were reported recently to be an intriguing and potential technique in detecting DVT in clinics. However, the photon transport is still unclear, which is crucial for the image reconstruction of the updated development called as NIRS-based DVT imager. Here we employed the Monte Carlo simulation software for 3D voxelized media (MCVM) and the Visible Chinese Human (VCH) model, which segmentation is finest in the world, to simulate multi-channel photon migration in calf muscle. And the image reconstruction of DVT hemodynamic distribution was achieved. This study, for the first time, provides the most realistic 3-D multichannel photon migration for NIRS study on DVT, and explored the image reconstruction for furtherly developing a NIRS-based DVT imager.

    Full Text Available In paroxysmal atrial fibrillation usually pulmonary veins isolation is enough, while in persistent and long-standing persistent forms ablation lines in the left atrium are needed. After that post ablational macroreentry tachycardia and focal atrial tachycardia, resistant to antiarrhythmic therapy, occur. Left atrial macroreentry tachycardia are localized perimitrally, around pulmonary veins and septally. There are also roof and posterior wall-associated macroreentry tachycardia. Considering relevance of postablation arrhythmias, we present our case report. A patient had paroxysmal atrial fibrillation. Pulmonary vein isolation was performed. After patient’s radiofrequency pulmonary vein isolation, three-dimensional map of left atrium was made using CARTO XP navigation system. Macroreentry tachycardia around left inferior pulmonary vein was revealed.There were fragmented potentials between left superior and left inferior pulmonary veins. An ablation lineconnecting inferior and superior pulmonary veins was made. After the completion of ablation line sinus rhythmwas restored.

    The purpose of this study was to evaluate the usefulness of multi-detector helical CT (MDHCT) with contrast medium in the diagnosis of deep vein thrombosis (DVT). The bilateral veins of the dorsal pedis in 45 patients (12 men, 33 women; average age, 64 years) under clinical suspicion of DVT were first punctured using 22-G needles. Then CT scanning from the level of the foot to the inferior vena cava was started 20 sec after the initial injection of 200 mL of dilute contrast medium (50 mL nonionic iodinated contrast medium of 300 mgI/mL and 150 mL saline) at a rate of 5 mL/sec. Two patients were excluded because of unsuccessful venous puncture. The average scanning time in 43 patients was 38.5{+-}7.9 seconds. Images of veins from the foot to the inferior vena cava were clearly demonstrated in each case. MDHCT showed DVT in 32 cases and patent deep vein in 11 cases. Simultaneous venography of the lower extremity in 18 patients clearly visualized DVT at the same level detected by contrast MDHCT. MDHCT for the diagnosis of DVT has the advantages of wider scanning rage, shorter scanning time, and finer Z-axis resolution than the other diagnostic modalities. (author)

    Upper-extremity deep vein thrombosis is common after pacemaker or cardioverter-defibrillator implantation. Only 1% to 3% of patients with upper-extremity deep vein thrombosis become symptomatic. Downhill esophageal varices develop in the upper third of the esophagus as a result of the obstruction of the superior vena cava. Herein, we report the case of a 54-year-old man—a recipient of multiple implanted cardiac pacemakers—who presented with bilateral upper-extremity deep vein thrombosis. This severely symptomatic condition was complicated by very rare and life-threatening downhill varices of the upper esophagus, but without bleeding. To the best of our knowledge, this is the 1st report of this array of conditions. PMID:21224954

    Hyperhomocysteinemia (HHcy) can be associated with deficiency of group B vitamins and folic acid. HHcy might also results from renal insufficiency, diabetes, hypothyreosis or malignant diseases. In same cases HHcy is connected with mutations of genes involved in its metabolism. HHcy causes the increased risk of arterial and vein thrombosis. In this paper we show case report of woman with HHcy, who developed several complications, probably because of HHcy. This patient in the age of 38 and 44 years developed twice myocardial infarction, whereas in the age of 48 she suffered from portal vein thrombosis. According to documentation, the level of cholesterol has never been elevated, however HHcy was observed. During diagnostic process, the primary and secondary causes of HHcy were assessed. Mutations of genes involved in Hcy metabolism were also assessed. We did not find any mutation in protein products of methylenotetrahydrofolate reductase (MTHFR) or cystationine beta-synthase (CBS). The patient was treated with the use of folic acid, vitamin B12 and B6 supplementation, and normalization of Hcy level was received. This case report underline, how important role in the case of HHcy play vitamin supplementation. The early treatment of HHcy might limit thromboembolic complication.

    Full Text Available Ovarian ependymomas are extremely rare tumors of the ovary. We present a case of a 67-year-old lady presented to us with swelling in the right side of neck for 2 months followed by pelvic pain, lower abdominal distention, and weight loss for 1 month. Her coagulation profile, blood chemistry, lipid profile, and tumor markers were within normal limits. Neck Doppler ultrasonography revealed thrombus in the right internal jugular vein and CT scan of the abdomen showed bilateral ovarian masses. Patient was subjected to debulking surgery for suspected ovarian cancer and microscopy revealed a highly cellular tumor composed of small cells with hyperchromatic, round-to-oval nuclei with scanty cytoplasm, and perivascular pseudorosettes. Diagnosis was confirmed by immunophenotype showing strong positivity to glial fibrillary acidic protein, estrogen receptors, and progesterone receptors. Patient was successfully managed with anticoagulants, adjuvant chemotherapy with BEP regimen, and letrozole. After ruling out other common conditions for thrombosis in this age group, this seems to be a paraneoplastic presentation of ovarian malignancy that preceded the diagnosis of ependymoma by 2 months. To the best of our knowledge this is the first case report in the world literature as “paraneoplastic internal jugular vein thrombosis leading to diagnosis of bilateral ovarian ependymoma.”

    Full Text Available Dynamic renal perfusion computerized tomographic (CT scan was performed to test the cortical and medullary perfusion in a patient with unilateral renal vein thrombosis secondary to idiopathic focal and segmental glomerulosclerosis (FSGS. Forty mL of Iohexol was injected intra-venously. Multiple fixed repeated axial renal CT scan cuts at specific intervals, over the mid pole, were recorded over 400 seconds. Radio density was measured over the aorta, cortex and medulla during that period. Graphs for the radio contrast density against time were plotted. Aortic, cortical and medullary perfusions were calculated by estimating the slopes of the curves. Based on the CT scan findings, perfusion of different parts of the kidney was measured. The reduction in kidney function with renal vein thrombosis seems to be secondary to hypoperfusion of renal cortex and medulla. Further studies are required to confirm this observation. The blood flow to the kidney im-proved within four days after therapy with anticoagulation and pulse steroids. The sequences of events that take place need further studies for validation.

    Portal vein tumor thrombosis (PVTT) is a common phenomenon in hepatocellular carcinoma (HCC). Compared to HCC without PVTT, HCC with PVTT is characterized by an aggressive disease course, worse hepatic function, a higher chance of complications related to portal hypertension and poorer tolerance to treatment. Conventionally, HCC with PVTT is grouped together with metastatic HCC during the planning of its management, and most patients are offered palliative treatment with sorafenib or other systemic agents. As a result, most data on the management of HCC with PVTT comes from subgroup analyses or retrospective series. In the past few years, there have been several updates on management of HCC with PVTT. First, it is evident that HCC with PVTT consists of heterogeneous subgroups with different prognoses. Different classifications have been proposed to stage the degree of portal vein invasion/thrombosis, suggesting that different treatment modalities may be individualized to patients with different risks. Second, more studies indicate that more aggressive treatment, including surgical resection or locoregional treatment, may benefit select HCC patients with PVTT. In this review, we aim to discuss the recent conceptual changes and summarize the data on the management of HCC with PVTT. PMID:27621575

    Pulmonary vein (PV) -encircling radiofrequency ablation frequently is effective in vagal atrial fibrillation (AF), and there is evidence that PVs may be particularly prone to cholinergically induced arrhythmia mechanisms. However, PV ablation procedures also can affect intracardiac autonomic ganglia. The present study examined the relative role of PVs versus peri-PV autonomic ganglia in an experimental vagal AF model. Cholinergic AF was studied under carbachol infusion in coronary perfused canine left atrial PV preparations in vitro and with cervical vagal stimulation in vivo. Carbachol caused dose-dependent AF promotion in vitro, which was not affected by excision of all PVs. Sustained AF could be induced easily in all dogs during vagal nerve stimulation in vivo both before and after isolation of all PVs with encircling lesions created by a bipolar radiofrequency ablation clamp device. PV elimination had no effect on atrial effective refractory period or its responses to cholinergic stimulation. Autonomic ganglia were identified by bradycardic and/or tachycardic responses to high-frequency subthreshold local stimulation. Ablation of the autonomic ganglia overlying all PV ostia suppressed the effective refractory period-abbreviating and AF-promoting effects of cervical vagal stimulation, whereas ablation of only left- or right-sided PV ostial ganglia failed to suppress AF. Dominant-frequency analysis suggested that the success of ablation in suppressing vagal AF depended on the elimination of high-frequency driver regions. Intact PVs are not needed for maintenance of experimental cholinergic AF. Ablation of the autonomic ganglia at the base of the PVs suppresses vagal responses and may contribute to the effectiveness of PV-directed ablation procedures in vagal AF.

    To evaluate the value of early identification and endovascular treatment of iliac vein compression syndrome (IVCS), with or without deep vein thrombosis (DVT). Three groups of patients, IVCS without DVT (group 1, n = 39), IVCS with fresh thrombosis (group 2, n = 52) and IVCS with non-fresh thrombosis (group 3, n = 34) were detected by Doppler ultrasonography, magnetic resonance venography, computed tomography or venography. The fresh venous thrombosis were treated by aspiration and thrombectomy, whereas the iliac vein compression per se were treated with a self-expandable stent. In cases with fresh thrombus, the inferior vena cava filter was inserted before the thrombosis suction, mechanical thrombus ablation, percutaneous transluminal angioplasty, stenting or transcatheter thrombolysis. Stenting was performed in 111 patients (38 of 39 group 1 patients and 73 of 86 group 2 or 3 patients). The stenting was tried in one of group 1 and in three of group 2 or 3 patients only to fail. The initial patency rates were 95% (group 1), 89% (group 2) and 65% (group 3), respectively and were significantly different (p = 0.001). Further, the six month patency rates were 93% (group 1), 83% (group 2) and 50% (group 3), respectively, and were similarly significantly different (p = 0.001). Both the initial and six month patency rates in the IVCS patients (without thrombosis or with fresh thrombosis), were significantly greater than the patency rates of IVCS patients with non-fresh thrombosis. From the cases examined, the study suggests that endovascular treatment of IVCS, with or without thrombosis, is effective

    Full Text Available With the objective of making advancements in the area of pro-thrombotic microparticle characterization in cardiovascular biology, we present a novel method to separate blood circulating microparticles using a membrane-based, nanopore filtration system. In this qualitative study, electron microscopy observations of these pro-thrombotic mouse microparticles, as well as mouse platelets and leukocytes obtained using a mouse inferior vena cava ligation model of deep-vein thrombosis are presented. In particular, we present mouse microparticle morphology and microstructure using SEM and TEM indicating that they appear to be mostly spherical with diameters in the 100 to 350 nm range. The nanopore filtration technique presented is focused on the development of novel methodologies to isolate and characterize blood circulating microparticles that can be used in conjunction with other methodologies. We believe that determination of microparticle size and structure is a critical step for the development of reliable assays with clinical or research application in thrombosis and it will contribute to the field of nanomedicine in thrombosis.

    Background. We studied the role of pulmonary veins in cancer progression using computed tomography (CT) scans. Methods. We obtained data from 260 patients with pulmonary vein obstruction syndrome (PVOS). We used CT scans to investigate pulmonary lesions in relation to pulmonary veins. We divided the lesions into central and peripheral lesions by their anatomical location: in the lung parenchymal tissue or pulmonary vein; in the superior or inferior pulmonary vein; and by unilateral or bilateral presence in the lungs. Results. Of the 260 PVOS patients, 226 (87%) had central lesions, 231 (89%) had peripheral lesions, and 190 (75%) had mixed central and peripheral lesions. Among the 226 central lesions, 93% had lesions within the superior pulmonary vein, either bilaterally or unilaterally. Among the 231 peripheral lesions, 65% involved bilateral lungs, 70% involved lesions within the inferior pulmonary veins, and 23% had obvious metastatic extensions into the left atrium. All patients exhibited nodules within their pulmonary veins. The predeath status included respiratory failure (40%) and loss of consciousness (60%). Conclusion. CT scans play an important role in following tumor progression within pulmonary veins. Besides respiratory distress, PVOS cancer cells entering centrally can result in cardiac and cerebral events and loss of consciousness or can metastasize peripherally from the pulmonary veins to the lungs.

    Full Text Available Left atrial tachycardia (AT has been reported to occur after pulmonary vein isolation (PVI for the treatment of atrial fibrillation (AF. We treated 3 patients who developed AT of different mechanisms following PVI. In case 1, focal AT originating at the ostium of the left superior PV was demonstrated and focal radiofrequency ablation was performed at the breakthrough point at the ostium of the left superior PV terminated the AT. In case 2, AT was shown to be counterclockwise macroreentrant AT around the left inferior PV through the conduction gap of the left sided posterior wall for which linear ablation was performed between left superior and inferior PVs. Focal ablation at the conduction gap terminated the AT. In case 3, a macroreentrant AT propagating around the mitral annulus was demonstrated and linear ablation between left inferior pulmonary vein and mitral annulus (mitral isthmus terminated the AT.

    A combination of giant hepatic hemangioma and diffuse hemangiomatosis is extremely rare in adults. Even when they are large, hemangiomas are soft and rarely compress adjacent structures. A 78-year-old man presented with abdominal pain and distension. Ultrasonography, computed tomography, and magnetic resonance imaging demonstrated a large expansile mass replacing the medial segment and caudate lobe with diffusely scattered nodules in the entire liver. The large hilar mass contained a central nonenhancing area and had a mass effect, leading to left portal vein occlusion. The image findings also revealed two unprecedented findings: left lateral segmental atrophy of the liver and recent portomesenteric vein thrombosis. The hepatic lesions were confirmed with hemangiomas by ultrasonography-guided biopsy. We diagnosed intrahepatic portal vein obstruction caused by a mass effect of giant hepatic hemangioma coexistent with diffuse hemangiomatosis, resulting in hepatic segmental atrophy and extrahepatic portal vein thrombosis.

    GI ischemia is a concerning adverse event of portal vein thrombosis (PVT). Minimally invasive techniques, such as visible light spectroscopy (VLS), have greatly improved the ability to diagnose GI ischemia. The aim of this study was to assess the clinical presentation and characteristics of GI ischemia in patients with PVT. Patients with noncirrhotic, nonmalignant PVT were included in this prospective cohort study. Clinical symptoms of GI ischemia were assessed by a structured questionnaire, VLS, and radiologic evaluation of the mesenteric vasculature. VLS measurements were compared with those in patients with cirrhosis and with a reference population. We included 15 patients with chronic PVT and 1 patient with acute PVT (median age 46.1 years [interquartile range [IQR], 30.9-53.7]; 44% male). Decreased mucosal oxygenation in at least 1 location of the GI tract was found in 12 patients (75%). Compared with the reference population (median 60.0 [IQR, 56.2-61.7]), VLS measurements were mostly decreased in the descending duodenum in patients with PVT (median 55.5 [IQR, 52.3-58.8]; P = .02) and patients with cirrhosis (median 52.0 [IQR, 46.5-54.0], P = .003). Symptoms typical for GI ischemia, such as postprandial pain and exercise-induced pain, were reported in 10 patients (63%) with PVT. In patients with extension of thrombosis into the superior mesenteric vein and splenic vein and/or presence of hypercoagulability, decreased VLS measurements were observed compared with historical control subjects. In patients with chronic PVT, GI ischemia is frequent. VLS enables objective and quantitative determination of GI mucosal ischemia. Onset of abdominal symptoms such as postprandial pain should prompt the physician to re-evaluate extent, cause, and treatment of PVT. Copyright © 2016 American Society for Gastrointestinal Endoscopy.

    Deep-vein thrombosis (DVT) resolves via a sterile inflammatory response. Defining the inflammatory response of DVT may allow for new therapies that do not involve anticoagulation. Previously, we have shown that Toll-like receptor 9 (Tlr9) gene deleted mice had impaired venous thrombosis (VT) resolution. Here, we further characterise the role of Tlr9 signalling and sterile inflammation in chronic VT and vein wall responses. First, we found a human precedent exists with Tlr9+ cells present in chronic post thrombotic intraluminal tissue. Second, in a stasis VT mouse model, endogenous danger signal mediators of uric acid, HMGB-1, and neutrophil extracellular traps marker of citrullinated histone-3 (and extracellular DNA) were greater in Tlr9-/- thrombi as compared with wild-type (WT), corresponding with larger VT at 8 and 21 days. Fewer M1 type (CCR2+) monocyte/macrophages (MØ) were present in Tlr9-/- thrombi than WT controls at 8 days, suggesting an impaired inflammatory cell influx. Using bone marrow-derived monocyte (BMMØ) cell culture, we found decreased fibrinolytic gene expression with exposure to several endogenous danger signals. Next, adoptive transfer of cultured Tlr9+/+ BMMØ to Tlr9-/- mice normalised VT resolution at 8 days. Lastly, although the VT size was larger at 21 days in Tlr9-/- mice and correlated with decreased endothelial antigen markers, no difference in fibrosis was found. These data suggest that Tlr9 signalling in MØ is critical for later VT resolution, is associated with necrosis clearance, but does not affect later vein wall fibrosis. These findings provide insight into the Tlr9 MØ mechanisms of sterile inflammation in this disease process.

    Full Text Available Background & objectives: Discrepancies exist in the reported prevalence of portal vein thrombosis (PVT, and its clinical characteristics and sites of occurrence need to be elucidated. The risk factors for PVT are also poorly understood. This single centre study was undertaken to determine the clinical characteristics, sites of occurrence, and risk factors associated with PVT in patients with liver cirrhosis. Methods: Hospitalized cirrhotic patients (N = 162 were segregated into the PVT and non-PVT groups. Indices possibly associated with PVT were measured and PVT was detected by both Doppler ultrasonography and computed tomography portal angiography. The portal vein diameter and flow velocity and splenic thickness were measured by ultrasonography. Results: PVT was found in 40 patients (24.7%; in 34 PVT patients (85%, the liver cirrhosis resulted from hepatitis B virus infections. Most (90% patients were Child-Pugh classes B and C, with similar distribution between the groups. PVT was seen in 20 patients in the portal and superior mesenteric veins; ascites, abdominal pain, gastrointestinal bleeding, and jaundice were common findings in PVT patients. Haemoglobin levels and blood platelet counts (BPCs were significantly lower and splenic thickness was greater in PVT than in non-PVT patients (P<0.01. There was a significant positive correlation between BPCs and platelet aggregation rates (R = 0.533, P<0.01. Interpretation & conclusions: The occurrence of PVT was 24.7 per cent, primarily in post-hepatitis B liver cirrhosis patients. PVT occurred mainly in the portal vein trunk and superior mesenteric vein. Different PVT sites may account for the differing clinical presentations. The lower levels of haemoglobin and BPCs as well as splenic thickening were associated with PVT. Splenic thickening may be a risk factor for PVT.

    Full Text Available Background Accurate identification of patients with deep vein thrombosis (DVT is critical, as untreated cases can be fatal. It is well established that the specificity of the clinical signs and symptoms of DVT is low. Therefore, clinicians rely on additional tests to make this diagnosis. There are three modalities for DVT diagnosis; clinical scoring, laboratory investigations, and radiology. The objective of this study was to determine the correlation of plasma D-dimer concentration with the ultrasonographic non-compressibility ratio in patients with DVT in the lower extremities. Methods This research was a cross-sectional observational study. The sample comprised 25 subjects over 30 years of age with clinically diagnosed DVT in the lower extremities. In all subjects, D-dimer determination using latex enhanced turbidimetric test was performed, as well as ultrasonographic non-compressibility ratio assessment of the lower extremities. Data were analyzed using Pearson’s correlation at significance level of 0.05. Results Mean plasma D-dimer concentration was 2953.00 ± 2054.44 mg/L. The highest mean non-compressibility ratio (59.96 ± 35.98% was found in the superficial femoral vein and the lowest mean non-compressibility ratio (42.68 ± 33.71% in the common femoral vein. There was a moderately significant correlation between plasma D-dimer level and non-compressibility ratio in the popliteal vein (r=0.582; p=0.037. In the other veins of the lower extremities, no significant correlation was found. Conclusion The sonographic non-compressibility ratio is an objective test for quick and accurate diagnosis of lower extremity DVT and for evaluation of DVT severity.

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

    Full Text Available Hepatocellular carcinoma (HCC is the third leading cause of cancer-related death worldwide. Portal vein tumor thrombosis (PVTT is a frequent entity in HCC, which strictly limits the gold standard treatment options such as surgical resection and transarterial chemoembolization. Therefore, the prognosis of patients with PVTT is extremely poor and an emergence of seeking an alternative option for intervention is inevitable. We present a case of a 60-year-old male patient with HCC induced PVTT who was subjected to the intraportal RFA and stenting-VesOpen procedure. No additional medical intervention was performed. The repeated CT performed 5 months after the VesOpen procedure revealed significant decrease of the tumor size, patent right, and main portal vein and a recanalization of the left portal vein, which was not processed. At this time point, liver functional tests, appetite, and general condition of the patient were improved evidently. This report designates the RFA as an instrumental option of therapeutic intervention for HCC patients with PVTT.

    The writing committee for Antithrombotic Therapy for Venous Thromboembolic Disease of the 2008 ACCP guidelines made the following recommendations for thrombus removal strategies in patients with deep vein thrombosis (DVT): open surgical thrombectomy is recommended in patients with acute iliofemoral DVT to reduce symptoms and post-thrombotic morbidity; whenever available, catheter-directed thrombolysis is preferred to surgical venous thrombectomy, the risk of hemorrhage being diminished; surgical venous thrombectomy is recognized to be efficient in cases where catheter-directed thrombolysis is unavailable or the patients are not suitable candidates for such a procedure. Randomized studies comparing surgical thrombectomy and anticoagulant therapy in patients with iliofemoral DVT (IFDVT) showed that at 6 months, 5 years, and 10 years the patients in the thrombectomy group presented increased permeability, lower venous pressure, less edema, and fewer postthrombotic symptoms compared to the patients receiving anticoagulant therapy. In this article we present 3 cases of IFDVT in postpartum patients diagnosed by Doppler ultrasound of the deep venous system. The 3 patients received anticoagulant therapy prior to surgery. Surgery consisted in thrombectomy of the common, superficial and deep femoral veins, external and internal iliac veins, and femoral-saphenous arteriovenous fistula. The patients received postoperative antithrombotic therapy and were followed-up at 3, 6 and 9 months by Doppler ultrasound of the deep venous system.

    Full Text Available We present a case of giant Splenorenal Shunt (SRS associated with portal vein thrombosis in a 37-year-old woman with a twelve-year history of autoimmune hepatitis/primary biliary cholangitis overlap syndrome. At the moment of the CT examination laboratory tests showed creatinine 1.5 mg/dl, bilirubin 1.5 mg/dl, INR 3, and Na 145 mmol/l and the Model End-Stage Liver Disease score was 24. Extensive calcified thrombosis causing complete occlusion of the portal vein lumen and partially occluding the origin of the superior mesenteric vein was present and a small calcified thrombus in the Splenic Vein lumen was also evident. SRS was located among the spleen hilum and the left kidney with a maximum diameter of 3.25 cm and was associated with dilatation of left renal vein and inferior vena cava. After a multidisciplinary evaluation the patient was put on the Regional Liver Transplant waiting list and liver transplantation was performed successfully. Although portal vein thrombosis and SRS are common occurrences in cirrhotic patients, the impact in the natural history of the disease is still unclear. Careful management and accurate imaging protocols are essential in the evaluation of those patients.

    Studies on the association between chronic osteomyelitis and deep vein thrombosis (DVT) and pulmonary thromboembolism (PE) are scarce. The aim of this study was to analyse a nationwide population-based database for association between DVT or PE after a diagnosis of chronic osteomyelitis. This nationwide population-based cohort study was based on data obtained from the Taiwan National Health Insurance Database from 1998 to 2008, with a follow-up period extending to the end of 2010. We identified patients with chronic osteomyelitis using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. The patients with chronic osteomyelitis and comparison controls were selected by 1:1 matching on a propensity score. The propensity score was calculated by a logistic regression to estimate the probability of the treatment assignment given the baseline variables including age, sex, and Charlson comorbidity index score. We analysed the risks of DVT and PE by using Cox proportional hazards regression models, including sex, age, and comorbidities. In total, 24,335 chronic osteomyelitis patients and 24,335 controls were enrolled in the study. The risk of developing DVT was 2.49-fold in patients with chronic osteomyelitis compared with the comparison cohort, after adjusting for age, sex, and comorbidities. The multiplicative increased risks of DVT were also significant in patients with chronic osteomyelitis with any comorbidity. In conclusion, physicians should consider chronic osteomyelitis in their evaluation of risk factors for DVT.

    While deep vein thrombosis (DVT) may be clinically suspected at several time points after major orthopedic surgery, clinical examination is often unreliable, and compression ultrasonography (CUS) screening at discharge is of limited value. A prospective cohort study was carried out in 1,033 consecutive patients who had undergone major hip or knee surgery, aimed to assess the accuracy of a strategy consisting of clinical investigation followed by CUS in the detection of proximal DVT before discharge. The circumferences of both legs were measured in all patients; those exhibiting >2 cm difference between them were considered to have suspected DVT, and underwent bilateral CUS. The same diagnostic workup was repeated on days 45 and 90 after surgery. Three patients developed pulmonary embolism (PE) during admission (one died). Five additional patients died before discharge. Routine clinical evaluation before discharge was done in 1,025 patients, and 105 (10%) had suspected DVT. CUS confirmed the diagnosis in 24 (2.3% of the overall series). After discharge, 59 patients had suspected DVT on day 45, 53 on day 90. DVT diagnosis was confirmed by CUS in 27 (26%). Three additional patients developed PE (1 fatal). This translates into a sensitivity of the routine examinations at discharge of 44%. A limited diagnostic workup for DVT before discharge has the capacity to identify 44% of those patients who will become symptomatic afterwards.

    Superficial vein thrombosis (SVT) may be associated with complications such as venous thromboembolism (VTE) and recurrent SVT. The purpose of this study was to explore risk factors among patients with a first isolated episode of SVT (index SVT) involving upper and lower extremities and to estimate the prevalence of VTE complications within 1 year of index SVT. Retrospective chart review of electronic records at Marshfield Clinic in Wisconsin identified 381 subjects with a first isolated SVT diagnosis (male/female: 170/211; median age 59.4 years). Patients were stratified based on whether they did (n = 44; 11.5 %) or did not (n = 337; 88.5 %) experience VTE complications and whether they did (n = 25; 6.6 %) or did not (n = 356; 93.4 %) experience pulmonary embolism (PE) and/or deep vein thrombosis (DVT) within 1 year of index SVT. There were 49 complications among 44 patients; these included DVT (n = 18, 36.7 %), propagation of SVT (n = 18, 36.7 %), PE (n = 9, 18.4 %), new SVT at different location (n = 3, 6.1 %), and recurrent SVT (n = 1, 2.0 %). Univariate analysis of all VTE complications identified seven potential risk factors and similar analysis of PE/DVT complications identified eight potential risk factors, with six common risk factors identified in both analyses. Multivariate analysis identified indwelling venous catheter 30 days prior to SVT (p = 0.044), cancer history with treatment in the previous year (p = 0.001), and non-surgical trauma 7 days prior to SVT (p PE/DVT complications. Independent risk factors identified in the current study may convey greater risk for VTE complications, especially PE/DVT, following an initial isolated SVT episode.

    Deep vein thrombosis (DVT) is a major health problem. Despite the wealth of studies on its epidemiology, few have described the thrombus sidedness and particularly the association of thrombus sidedness with clinical presentation and subsequent complications. This article reviews current knowledge regarding this topic and in light of recent data from a large prospective study. This is the first report from the prospective National Research Institute of Tuberculosis and Lung Disease DVT registry. Patients with ultrasound-confirmed symptomatic DVT were enrolled, and thrombus sidedness was investigated in each case. Computed tomography pulmonary angiography was used to diagnose coexisting pulmonary embolism (PE) in DVT patients with suggestive symptoms. Embolic burden score was calculated for those with PE. From the total of 100 patients, 45 had left-sided DVT, 41 had right-sided DVT, and 14 had bilateral DVT. Presenting symptoms and comorbidities were comparable, except for cancer, which was more common in those with right-sided involvement (either right-sided or bilateral DVT; P = 0.004). Compared with those with left-sided DVT, PE happened more frequently in right-sided DVT patients. Right-sided DVT patients also had a higher rate of massive PE ( P = 0.03) and a greater mean embolic burden (13.32 ± 1.63 versus 6.05 ± 1.06; P = 0.001). These findings support raised awareness for global reconsideration of the assumption of complete identicalness of right-sided and left-sided DVT. Although future studies are needed to better elucidate epidemiological and prognostic differences based on the thrombus sidedness, our preliminary findings suggest that the two are not completely identical and right-sided DVT might be more ominous.

    Aseptic cavernous sinus thrombosis (CST) is rare and may clinically masquerade as a carotid cavernous fistula. Conventional management includes oral anticoagulation, but cases of ocular hypertension affecting vision may require more aggressive intervention. We report a case of a woman with spontaneous bilaterally occluded cavernous sinuses with elevated intraocular pressure (IOP), which resolved immediately following unilateral superior ophthalmic vein (SOV) sacrifice. She was subsequently placed on oral anticoagulants. By 4 months postoperatively her IOP was normalized and her vision had improved. Repeat angiography demonstrated stable venous filling, with some mild improvement of flow through the cavernous sinus. Coil-mediated sacrifice of the SOV might be an effective means to relieve ocular hypertension and preserve vision in the setting of aseptic CST.

    The purpose of this paper is to provide an in-depth analysis of computer aided system for the early diagnosis of Deep Vein Thrombosis (DVT). Normally, patients are diagnosed with DVT through ultrasound examination after they have a serious complication. Thus, this study proposes a new approach to reduce the risk of recurrent DVT by tracking the venous valve movement behaviour. Inspired by image processing technology, several image processing methods namely, image enhancement, segmentation and morphological have been implemented to improve the image quality for further tracking procedure. In segmentation, Otsu thresholding provides a significant result in segmenting valve structure. Subsequently, morphological dilation method is able to enhance the region shape of the valve distinctly and precisely. Lastly, image subtraction method is presented and evaluated to track the valve movement. Based on the experimental results the normal range of valve velocity lies within the range of blood flow velocity (Vb) and occasionally may result in higher values.

    This paper reports a prospective audit, against an existing baseline standard, for intermittent pneumatic compression (IPC) in the prophylaxis of asymptomatic deep vein thrombosis (DVT). This was done via a structured questionnaire, using the methodology of total population sampling, encapsulating all theatre staff within one NHS trust. With regards to the standard, performance is good, as IPC is DVT prophylaxis of choice in the perioperative area and is used frequently on most patients. The findings of the audit do, however, highlight the need for appropriate local DVT risk assessment guidelines, essential to ensure that prophylaxis is administered to the correct at risk groups, as prevention may be unjustified in low risk groups and possibly inappropriate for the same regimen to be used for all patients.

    We report the rare case of a splenic inflammatory pseudotumor associated with massive splenomegaly, diagnosed after surgery. A 51-year-old woman was admitted to our hospital for investigation of anemia. Physical examination revealed a palpable left upper quadrant mass. Computed tomography and magnetic resonance imaging showed a splenic mass, 20 cm in diameter. We performed splenectomy for both diagnosis and treatment. The spleen weighed 2400 g, and histologic examination of the mass confirmed an inflammatory pseudotumor. Portal vein thrombosis (PVT) developed the day after surgery, but resolved with anticoagulation therapy. This case highlights that there is a risk of PVT after splenectomy in patients with massive splenomegaly, and that anticoagulant therapy should be initiated promptly.

    True crural artery aneurysm is a rare clinical entity. Crural artery aneurysms are most frequently seen in men in their sixth decade without major cardiopulmonary diseases and are often associated with injury, superinfection, or vasculitis. We report the case of a 44-year-old man with a history of idiopathic deep vein thrombosis (DVT) as the first manifestation of a true crural artery aneurysm. To our knowledge, DVT is very rarely related with true crural artery aneurysms, with only 3 cases reported in the current literature. Open surgical repair is the most common management, with ligation as a second option in emergencies such as rupture. The related literature is discussed. We conclude that crural aneurysms should be considered in differential diagnosis of popliteal DVT in adults. True crural aneurysms need vigilance and a more systematical approach to provide physicians the means to the best medical care.

    Neonatal renal vein thrombosis is a rare condition. The present case is rather unfrequent and particularly educative since it shows the complete diagnostic triad including hematuria, flank mass and thrombocytopenia. The diagnosis relies on the demonstration, by Doppler ultrasound, of an obstructed renal venous bed. The investigation is completed by a platelet count and the determination of the prothrombin time, of the activated partial thromboplastin time as well as of the concentration of fibrinogen. The screening also includes the search for a possible etiology, such as a deficiency in coagulation proteins, the presence of antiphospholipid antibodies or of a genetic mutation of one of the coagulation factors. Since there exist no evidence based guidelines for the management of the disease, we will discuss the diagnosis and treatment in relation with the published literature.

    Spontaneous renal vein thrombosis (RVT) is very rare in the absence of nephrotic syndrome. It is more common in newborns and infants. RVT should always be included in the differential diagnosis of flank pain and hematuria, and because RVT can induce acute renal injury. A 19-year-old man was admitted to our hospital because he complained of right flank pain and oliguria for 3 days. Another patient, a 24-year-old man, complained of a severe and sudden onset of bilateral flank pain and anuria for a day. They were both healthy before they developed the described symptoms and had different levels of decrease in renal function when they visited the hospital. Color Doppler ultrasonography revealed RVT in both the patients. The patients received therapy, including anticoagulation and thrombolysis, following their diagnoses, and they recovered in a few days.

    Neonatal renal vein thrombosis (NRVT) is a rare thromboembolic complication in the neonatal period, and sequelae from renal dysfunction can cause significant morbidity. The authors retrospectively reviewed 10 patients with NRVT treated at their institution. The majority of the cohort were male (n = 9), preterm (n = 6), and had unilateral NRVT (n = 6). Six patients received thrombolysis and/or anticoagulation, and 4 patients received supportive care only. Two of the 6 patients treated with anticoagulation who had bilateral NRVT and anuria received thrombolysis with low-dose tissue plasminogen activator. Thrombolysis was not associated with any major adverse events, and both patients had marked improvement of renal function. Eight patients subsequently developed renal atrophy (3 received anticoagulation, 2 received thrombolysis with anticoagulation, and 3 received supportive care). Anticoagulation/thrombolysis did not appear to prevent renal atrophy. The role of thrombolysis needs to be further studied and considered in the setting of bilateral NRVT and acute renal failure.

    Venous volume (venous capacity) of the calf is low in patients with acute myocardial infarction, who also have a high risk of deep vein thrombosis (DVT). The effect of graduated compression stockings on the venous volume and on the incidence of DVT was therefore studied in 80 patients aged 70 years and above with acute myocardial infarction. Graduated compression stockings were randomly fitted to one leg, the other serving as a control, after which the venous volume was measured by strain gauge plethysmography. The incidence of DVT was measured by the 125I fibrinogen uptake test. Venous volume was significantly higher in legs treated with graduated compression stockings compared to control legs. DVT developed in eight control legs but not in any leg treated with graduated compression stockings (P = 0.003). DVT was also significantly more frequent in women compared to men and the majority of DVT developed in legs with very low venous volume values.

    The anatomy of the thrombus in acute deep vein thrombosis (DVT) in women using oral contraceptives was studied in 277 reports on DVT received by the Swedish Adverse Drug Reaction Advisory Committee (SADRAC). The study revealed a similarity between the anatomy of DVT in women on oral contraceptives and that of DVT in pregnant women, suggesting a pharmacologic influence of the hormones in the pill on the pathogenesis of DVT in women on oral contraceptives. The anatomy of DVT in women on low-estrogen pills was identical with that of DVT in women on high-estrogen pills, suggesting an identical pharmacologic influence of the two types of pill on the pathogenesis of DVT in women on oral contraceptives.

    A 68-year-old female presented with a week history of fever and generalized weakness. Clinical examination, blood work and urinalysis were compatible with sepsis due to acute pyelonephritis. Urine cultures were positive for Escherichia coli and blood cultures were negative. After 5 days of antibiotic therapy with cefuroxime, inflammatory parameters (CRP level and white blood cell count) remained highly elevated. Abdominal CT scan showed right kidney pyelonephritis with renal and perirenal abscess and right renal vein thrombosis. The patient improved after percutaneous drainage of the perirenal abscess and anticoagulation treatment. She was discharged on hospital day 14.

    Imaging findings of bilateral pulmonary vein atresia have not been described. To describe cardiac CT findings and clinical outcomes of bilateral pulmonary vein atresia. Three newborns with bilateral pulmonary vein atresia were encountered at our institution during a period of 8 years. We evaluated prenatal echocardiographic findings, clinical presentations, postnatal echocardiographic findings, chest radiographic findings, cardiac CT findings and clinical outcomes. All newborns presented immediately after birth with severe cyanosis, respiratory distress and acidosis that were unresponsive to medical management. Prenatal and postnatal echocardiographic studies and chest radiography were misleading, inconclusive or nonspecific in making the diagnosis in these children; however cardiac CT clearly demonstrated atresia of the bilateral pulmonary veins with multiple small mediastinal collateral veins and pulmonary edema. Surgical treatments were not feasible for this anomaly. Their clinical outcomes were universally dismal and all infants died within 3 days. Cardiac CT provides an accurate diagnosis of bilateral pulmonary vein atresia and leads to prompt treatment decision in these children. (orig.)

    Full Text Available R Kreidy1, N Irani-Hakime21Department of Vascular Surgery, 2Department of Laboratory Medicine, Saint George Hospital, University Medical Center, University of Balamand, Beirut, LebanonAim: Factor V Leiden (R506Q mutation is the most commonly observed inherited genetic abnormality related to vein thrombosis. Lebanon has one of the highest frequencies of this mutation in the world with a prevalence of 14.4% in the general population. The aim of this study is to define risk factors including inherited genetic abnormalities among Lebanese patients with lower extremity deep vein thrombosis. We report the clinical outcome of patients with thrombophilia.Methods: From January 1998 to January 2008, 162 patients (61 males and 101 females were diagnosed with lower extremity deep vein thrombosis. Mean age was 61 years (range: 21 to 95 years.Results: The most frequent risk factors for vein thrombosis were surgery, advanced age, obesity, and cancer. Twenty-five patients had thrombophilia, 16 patients had factor V Leiden (R506Q mutation, and seven patients had MTHFR C677T mutation. Ninety-two percent of patients screened for thrombophilia were positive. Screening was requested in young patients (16, patients with recurrent (11, spontaneous (8, and extensive (5 venous thrombosis, familial history (5, pregnancy (4, estroprogestative treatment (3, and air travel (1. Nine patients had one, 11 patients had two, and five had three of these conditions. Follow-up (6 to 120 months of these 25 patients treated with antivitamin K did not reveal recurrences or complications related to venous thromboembolism.Conclusion: Factor V Leiden mutation followed by MTHFR mutation are the most commonly observed genetic abnormalities in these series. Defining risk factors and screening for thrombophilia when indicated reduce recurrence rate and complications. Recommendations for thrombophilia screening will be proposed.Keywords: venous thrombosis, risk factors, genetics, factor V

    AIM: To evaluate the effect of portal vein thrombosis and arterioportal shunts on local tumor response in advanced cases of unresectable hepatocellular carcinoma treated by transarterial chemoembolization. METHODS: A retrospective study included 39 patients (mean age: 66.4 years, range: 45-79 years, SD: 7) with unresectable hepatocellular carcinoma (HCC) who were treated with repetitive transarterial chemoembolization (TACE) in the period between March 2006 and October 2009. The effect of portal vein thrombosis (PVT) (in 19 out of 39 patients), the presence of arterioportal shunt (APS) (in 7 out of 39), the underlying liver pathology, Child-Pugh score, initial tumor volume, number of tumors and tumor margin definition on imaging were correlated with the local tumor response after TACE. The initial and end therapy local tumor responses were evaluated according to the response evaluation criteria in solid tumors (RECIST) and magnetic resonance imaging volumetric measurements. RESULTS: The treatment protocols were well tolerated by all patients with no major complications. Local tumor response for all patients according to RECIST criteria were partial response in one patient (2.6%), stable disease in 34 patients (87.1%), and progressive disease in 4 patients (10.2%). The MR volumetric measurements showed that the PVT, APS, underlying liver pathology and tumor margin definition were statistically significant prognostic factors for the local tumor response (P = 0.018, P = 0.008, P = 0.034 and P = 0.001, respectively). The overall 6-, 12- and 18-mo survival rates from the initial TACE were 79.5%, 37.5% and 21%, respectively. CONCLUSION: TACE may be exploited safely for palliative tumor control in patients with advanced unresectable HCC; however, tumor response is significantly affected by the presence or absence of PVT and APS.

    2003-12-01

    Full Text Available Abstract Introduction Deep vein thrombosis (DVT is a serious health problem that affects more than 2 million people annually in the United States. Many of these patients develop asymptomatic DVT, but months to years later may experience symptomatic post-thrombotic syndrome (PTS. It is not known how many cases of PTS can be traced to "asymptomatic" DVT because venography is no longer routinely done and ultrasonography (US may miss some asymptomatic clots. As a result, a clinical tool in addition to US to detect symptom emergence or exacerbation in patients after DVT would be of value. Methods Seventy-seven patients hospitalized with an acute DVT interviewed by telephone at 3–7 days, 30–40 days, and 12-months following discharge were included in this report. All were treated with a standard anticoagulation "Clinical Pathway Protocol" between April 1999 and January 2000. Using a 14-item Deep Vein Thrombosis Leg Symptom Index (DVT-LSI, patients were queried regarding leg pain, swelling, skin discoloration, cosmetic appearance, activity tolerance, emotional distress, and leg-related sleep problems. Results The DVT-LSI for each leg was reliable at all assessments, with instrument reliability (alpha coefficients greater than 0.70 at all time points (range 0.71–0.87. DVT-LSI scores, and the percentage of patients exhibiting symptoms, were higher in the DVT-affected leg at all time points. Among patients with unilateral disease, symptom severity ratings were significantly worse for patients in the affected leg compared to the normal leg at all time points, with the exception of those with a right-leg DVT at 12 months. Patients with bilateral thrombi did not have different scores on one leg compared to the other. Conclusion The DVT-LSI is useful in assessing symptomatic clinical outcomes in patients after diagnosis of DVT, and may represent a surrogate marker for DVT otherwise presumed to be asymptomatic.

  2. Emergency Department Management of Suspected Calf-Vein Deep Venous Thrombosis: A Diagnostic Algorithm

    2016-06-01

    Full Text Available 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.

    2013-01-01

    Full Text Available Background: Elevated plasma homocysteine (Hcy level has been established as a significant risk factor for venous thrombosis and cardiovascular disease. Homozygosity for the methylenetetrahydrofolate reductase (MTHFR C677T mutation has been associated with elevated plasma Hcy concentration and may contribute to retinal vein thrombosis (RVT development. The aim of the present study was to investigate whether the hyperhomocysteinemia and/or homozygosity for the MTHFR C677T mutation are associated with an increased risk for RVT. Materials and Methods: Our study population consisted of 73 consecutive patients (50-78 years old with RVT and 73 control subjects (51-80 years old, matched for age and sex. Genotyping for the MTHFR C677T mutation was performed by polymerase chain reaction-restriction fragment length polymorphism technique and Hcy level was determined by an enzyme immunoassay kit. Results: The prevalence of 677TT genotype was higher in patients than control subjects, but the difference in frequency didn′t reach a significant value (P = 0.07. The frequency of the 677T allele was 26% and 21.2% in patients and controls, respectively and did not differ significantly between the two groups (odds ratio = 1.3, 95% confidence interval (0.75-2.24, P = 0.33. Fasting plasma total Hcy level was significantly higher in patients than controls (P = 0.001. Conclusion: Our study demonstrated that hyperhomocysteinemia, but not the MTHFR C677T mutation, is associated with RVT.

  5. Radiotherapy as valid modality for hepatocellular carcinoma with portal vein tumor thrombosis.

    Yu, Jeong Il; Park, Hee Chul

    2016-08-14

    Although the current standard treatment for hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is sorafenib, many previous studies have established the need for a reliable local modality for PVTT control, which is a major cause of liver function deterioration and metastasis. Additionally, there is growing evidence for the prognostic significance of PVTT classification according to the location of tumor thrombosis. Favorable outcomes can be obtained by applying local modalities, including surgery or transarterial chemoembolization, especially in second-order or distal branch PVTT. Rapid control of PVTT could maintain or improve liver function and reduce intrahepatic as well as distant metastasis. Radiotherapy (RT) is one of the main locoregional treatment modalities in oncologic fields, but has rarely been used in HCC because of concerns regarding hepatic toxicity. However, with the development of advanced techniques, RT has been increasingly applied in HCC management. Randomized studies have yet to definitively prove the benefit of RT, but several comparative studies have justified the application of RT in HCC. The value of RT is especially noticeable in HCC with PVTT; several prospective and retrospective studies have reported favorable outcomes, including a 40% to 60% objective response rate and median overall survival of 15 mo to 20 mo in responders. In this review, we evaluate the role of RT as an alternative local modality in HCC with PVTT.

    2011-03-01

    Full Text Available Ramsay-Hunt Syndrome (RHS is a rare affection characterized by peripheral facial paralysis (PFP, skin eruption in the auricular canal and cochleovestibular symptoms. It is produced by varicella-zoster virus(VZV reactivation at the geniculate ganglia. In elderly and immunocompromised individuals, the virus may reactivate to produce shingles (zoster. After zoster resolves, many elderly patients experience postherpetic neuralgia. Uncommonly, VZV can spread to large cerebral arteries to cause a spectrum of large-vessel vascular damage, ranging from vasculopathy to vasculitis, with stroke. In immunocompromised individuals, especially those with cancer or acquired immunodeficiency syndrome, deeper tissue penetration of the virus may occur (as compared with immunocompetent individuals, with resultant myelitis, small-vessel vasculopathy, ventriculitis, and meningoencephalitis. The polymerase chain reaction (PCR analysis of cerebrospinal fluid remains the mainstay for diagnosing the neurologic complications of VZV during life. We report a case of Ramsay Hunt syndrome complicated with cerebral venous thrombosis. Patient received treatment with acyclovir and anticoagulation. Early treatment with acyclovir therapy and anticoagulation could improve the recovery rate of facial nerve palsy and sinus vein thrombosis.

  8. Study of Vessel Conditions in Different Categories of Weight for Early-Stage of Deep Vein Thrombosis (DVT Diagnosis

    Directory of Open Access Journals (Sweden)

    Noor Hafizzatul ‘Izzah bt Mat Harun

    2015-02-01

    Full Text Available In this paper, the clinical experiment study is presented to diagnose the Deep Vein Thrombosis (DVT. The diagnosis of DVT is commonly used by monitoring the blood velocity and the present of thrombus in vessel from B-mode ultrasound image associated with the application of Doppler ultrasound. However, the monitoring of those parameters will only be confirmed when someone had already suffered from DVT disease. Thus, this study is to diagnose the early stage of DVT. Since it is difficult to recognize the vessel condition at the early stage of DVT, the evaluation of vein mechanism based on different categories of weight at the early stage of DVT is proposed. The wall displacement and blood flow velocity is considered to be the important parameters to construct a clinical model of DVT risk factor, thereby constitutes an important contribution for predicting probability of Deep Vein Thrombosis (DVT.

    We report our experience using catheter-directed thrombectomy/thrombolysis (CDT) to treat a patient with acute renal vein thrombosis (RVT) associated with systemic lupus erythematosus (SLE). A 34-year-old woman presented with persistent left flank pain, and a renal ultrasonography examination revealed an enlarged left kidney. Contrast-enhanced computed tomography confirmed the presence of acute left RVT. Because medical treatment failed to relieve her pain and the renal function was deteriorating, we attempted to salvage the occluded left renal vein using an endovascular approach. The pain was completely relieved after a CDT and an overnight urokinase infusion. A follow-up computed tomography examination revealed the complete resolution of the thrombus. The creatinine level returned to normal (1.7-0.4 mg/dL), along with contrast enhancement in the left kidney, and this suggested the preservation of renal function. To our knowledge, this is the first report utilizing CDT to treat SLE-associated RVT. When the renal function is deteriorating, CDT is worth considering for RVT if conventional medical treatment has failed. © 2016 Wiley Periodicals, Inc.

    Pulmonary embolism (PE) is a deceptive condition which is often incorrectly diagnosed leading to high morbidity and mortality. We present a case where symptoms were localised to different areas of the body starting with post-traumatic pain over lower extremity varicosities that migrated sequentially over a month to the knee, hip, back, abdomen and chest finally presenting as syncope. Despite a low pre-test clinical probability, a very high index of suspicion led to a timely diagnosis of a massive bilateral PE that eventually caused a troponin leak. The aetiology is highly suspicious of a thrombus which originated in the veins of the leg due to trauma over varicose veins.The case described here exemplifies the importance of considering trauma to varicosities as a risk factor for embolism when the clinical picture is concerning but other signs and symptoms of PE are not apparent.

    2006-01-01

    The purpose of this work was to describe our experience in performing pulmonary angiography using the Hunter pulmonary catheter, manufactured by Cook, Inc., which is a modified 6F pigtail catheter with a "C-shaped" curve, designed for a brachiocephalic vein approach. One hundred twenty-three patients underwent pulmonary angiograms using the Hunter catheter between August 1997 and January 2002. Operator comments were gathered in 86 (70%) of the cases. The operator was, if possible, the most junior resident on the service. Thirty-nine operators participated in the survey. Efficacy, safety, and ease of use of the catheter were determined by operators' comments and ECG observations during the procedure. Corroborating clinical data were gathered from medical records. In 68 (79%) of the procedures that were commented upon, the operator described insertion into the pulmonary artery (PA) as easy; only 2 (2%) indicated difficulty in accessing the PA. In 41 (63%) of the bilateral angiograms that were commented upon, the operator described accessing the left PA from the right PA as easy; only 6 (9%) rated it as difficult and all were with an older technique in which the catheter was withdrawn to the pulmonary bifurcation without a wire or with only the soft tip of the wire in the pigtail and then rotated to the left main pulmonary artery. Thirty-one of the 41 patients who demonstrated premature ventricular contractions (PVCs) had a previous history of heart disease. Nineteen of the 39 patients who did not have PVCs had a history of heart disease (p = 0.018). The maneuverability and shape of the Hunter catheter make pulmonary angiography an easy procedure, even for operators with minimal experience and limited technical proficiency. PVCs demonstrated a statistically significant correlation with a positive patient history for cardiac disease, rather than being a universal risk.

    Venous thrombosis, including deep vein thrombosis and pulmonary embolism, occurs at an annual incidence of about 1 per 1000 adults. Rates increase sharply after around age 45 years, and are slightly higher in men than women in older age. Major risk factors for thrombosis, other than age, include exogenous factors such as surgery, hospitalization, immobility, trauma, pregnancy and the puerperium and hormone use, and endogenous factors such as cancer, obesity, and inherited and acquired disorde...

    A 22-year-old Japanese woman was found to have severe esophageal varices and then suffered from hepatic encephalopathy. She was diagnosed with Budd-Chiari syndrome (BCS) due to hepatic vein (HV) thrombosis accompanied by portal vein thrombosis without inferior vena cava (IVC) obstruction. Latent myeloproliferative neoplasm (MPN) lacking the JAK2-V617F mutation was considered to be the underlying disease. Liver transplantation was strikingly effective for treating the clinical symptoms attributable to portal hypertension. Although thrombosis of the internal jugular vein occurred due to thrombocythemia, which manifested after transplantation despite anticoagulation therapy with warfarin, the thrombus immediately disappeared with the addition of aspirin. Neither thrombosis nor BCS has recurred in more than 4 years since the amelioration of the last thrombotic event, and post-transplant immunosuppression with tacrolimus has not accelerated the progression of MPN. In Japan, IVC obstruction, which was a predominant type of BCS, is suggested to have decreased in incidence with recent improvements in hygiene. The precise diagnosis of BCS and causative underlying diseases should be made with attention to the current trend of the disease spectrum, which fluctuates with environmental sanitation levels. Because the stepwise strategy, including liver transplantation, has been proven effective for patients with pure HV obstruction in Western countries, this strategy should also be validated for utilization in Japan and in developing countries where HV obstruction potentially predominates.

    In this study, we propose to use optical coherence tomography to enable a direct visualization of myocardium extending into the pulmonary vein (PV). The results showed that there are obvious differences in the morphology of myocardium and fibrous tissue in the transition region of myocardial sleeve, which is in agreement with the histological analysis. In addition, the myocardial area in transition point has three layers in the depth of 1 mm, and the depth-resolved myocardial fiber show different orientation in the different layers. This characteristic was applied for segmentation of the structures of myocardium extending into PV.

    There is good evidence demonstrating that outpatient management of deep venous thrombosis (DVT) is feasible and safe. However, few emergency departments in Ireland have implemented care pathways for outpatient management of DVT. The aim of this study was to examine the safety and efficacy of implementing an Emergency Department (ED)- care pathway for outpatient management of patients with DVT. A retrospective observational study of this care pathway introduced at our institution was performed. The primary outcome measure was the number of hospital admissions avoided by using the care pathway. Two hundred and eighty-four patients presenting to the ED with suspected lower limb DVT, were managed using the care pathway over a 6 month period. Forty-nine patients (17%) had a DVT diagnosed. Thirty-nine patients (81%) were suitable for outpatient DVT management. Ten patients (19%) were admitted to hospital. At 3 months there were no reported cases of the following complications: missed DVT, pulmonary embolism or death.

    Standard donor lung assessment relies on imaging, challenge gases and subjective interpretation of bronchoscopic findings, palpation and visual assessment. Central gases may not accurately represent true quality of the lungs. We report our experience using selective pulmonary vein gases to corroborate the subjective judgement. Starting, January 2012, donor lungs have been assessed by intraoperative bronchoscopy, palpation and visual judgement of lung collapse upon temporary disconnection from ventilator, central gases from the aorta and selective pulmonary vein gases. Partial pressure of oxygen (pO2) <300 mmHg on FiO2 of 1.0 was considered low. The results of the chest X-ray and last pO2 in the intensive care unit were also collected. Post-transplant primary graft dysfunction and survival were monitored. To date, 259 consecutive brain-dead donors have been assessed and 157 transplants performed. Last pO2 in the intensive care unit was poorly correlated with intraoperative central pO2 (Spearman's rank correlation rs = 0.29). Right inferior pulmonary vein pO2 was associated (Mann-Whitney, P < 0.001) with findings at bronchoscopy [clean: median pO2 443 mmHg (25th-75th percentile range 349-512) and purulent: 264 mmHg (178-408)]; palpation [good: 463 mmHg (401-517) and poor: 264 mmHg (158-434)] and visual assessment of lung collapse [good lung collapse: 429 mmHg (320-501) and poor lung collapse: 205 mmHg (118-348)]. Left inferior pulmonary pO2 was associated (P < 0.001) with findings at bronchoscopy [clean: 419 mmHg (371-504) and purulent: 254 mmHg (206-367)]; palpation [good: 444 mmHg (400-517) and poor 282 mmHg (211-419)] and visual assessment of lung collapse [good: 420 mmHg (349-496) and poor: 246 mmHg (129-330)]. At 72 h, pulmonary graft dysfunction 2 was in 21/157 (13%) and pulmonary graft dysfunction 3 in 17/157 (11%). Ninety-day and 1-year mortalities were 6/157 (4%) and 13/157 (8%), respectively. Selective pulmonary vein gases provide corroborative objective

    Full Text Available BACKGROUND: Pulmonary thromboembolism is a common cause of death in patients with autopsy-confirmed Parkinsonism. This study investigated the incidence of leg deep vein thrombosis in Parkinson's disease and relationships between deep vein thrombosis and clinical/laboratory findings, including postural abnormalities as assessed by photographic measurements. METHODS: This cross-sectional study assessed the presence of deep vein thrombosis using bilateral leg Doppler ultrasonography in 114 asymptomatic outpatients with Parkinson's disease. RESULTS: Deep vein thrombosis was detected in 23 patients (20% with Parkinson's disease. Deep vein thrombosis was located in the distal portion in 18 patients and in the proximal portion in 5 patients. No significant differences in age, sex, body mass index, disease duration, Hoehn-Yahr stage, anti-Parkinson's drugs, or daily levodopa-equivalent dose were seen between deep vein thrombosis-positive and -negative groups. Univariate analysis for developing deep vein thrombosis in patients with Parkinson's disease identified the following markers: long-term wheelchair use, bent knee, bent spine, and D-dimer elevation. Bending angles were significantly greater in the deep vein thrombosis-positive group at the knee and spine than in the deep vein thrombosis-negative group. Half of Parkinson's disease patients with camptocormia had deep vein thrombosis. Among diabetes mellitus cases, long-term wheelchair use, bent knee over 15°, camptocormia, D-dimer elevation, the more risk markers were associated with a higher incidence of DVT. The presence of risk markers contributed to the development of deep vein thrombosis. On multivariate logistic regression analysis, a bent knee posture was strongly associated with an increased risk of deep vein thrombosis. CONCLUSION: Presence of leg deep vein thrombosis correlated with postural abnormalities in Parkinson's disease. We recommend non-invasive ultrasonographic screening for leg

    Full Text Available Jugular venous thrombosis infrequently could be secondary to malignancy and has seldom been reported secondary to mediastinal large B-cell lymphomas. The postulated mechanisms are mechanical compression that leads to stagnation of blood in the venous system of the neck and/or an increase in the circulating thrombogenic elements that could cause venous thromboembolism as a paraneoplastic phenomenon. We report the case of a middle aged male presenting with right sided neck pain and arm swelling secondary to ipsilateral jugular-subclavian deep vein thrombosis. Investigations revealed it to be secondary to a mediastinal mass shown on CT scan of the chest.

    This prospective study evaluated the ability of indirect 16-row multidetector CT venography, in comparison with Doppler sonography, to detect deep vein thrombosis after total hip or knee replacement. Sixty-two patients had undergone orthopedic replacement surgery on a total of 30 hip joints and 54 knee joints. The CT venography (scan delay time: 180 seconds; slice thickness/increment: 2/1.5 mm) and Doppler sonography were performed 8 to 40 days after surgery. We measured the z-axis length of the beam hardening artifact that degraded the image quality so that the presence of deep vein thrombosis couldn't be evaluated on the axial CT images. The incidence and location of deep vein thrombosis was analyzed. The diagnostic performance of the CT venograms was evaluated and compared with that of Doppler sonography as a standard of reference. The z-axis length (mean{+-}standard deviation) of the beam hardening artifact was 4.5{+-}0.8 cm in the arthroplastic knees and 3.9{+-}2.9 cm in the arthroplastic hips. Deep vein thrombosis (DVT) was found in the popliteal or calf veins on Doppler sonography in 30 (48%) of the 62 patients. The CT venography has a sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 90%, 97%, 96%, 91% and 94%, respectively. The ability of CT venography to detect DVT was comparable to that of Doppler sonography despite of beam hardening artifact. Therefore, CT venography is feasible to use as an alternative modality for evaluating postarthroplasty patients.

    Full Text Available Abstract Introduction Spontaneous intrauterine arterial thrombosis and congenital pulmonary hypoplasia are rare conditions and have not been reported to occur together. The literature rather includes two reports of babies with neonatal pulmonary artery occlusion and post-infarction cysts of the lungs. Case presentation We report a case of a live Caucasian male newborn with left lung hypoplasia that occurred in association with left pulmonary artery thrombosis. Despite a critical neonatal course, including extracorporeal membrane oxygenation, this infant is alive and well at 18 months of age without any neurodevelopmental sequelae or reactive airway disease. Conclusion This association suggests the possibility of an intrauterine vascular event between the fifth and eighth weeks of gestation during early pulmonary artery and lung development.

    Tony Zitek, MD

    2016-03-01

    Full Text Available Introduction: Two-point compression ultrasound is purportedly a simple and accurate means to diagnose proximal lower extremity deep vein thrombosis (DVT, but the pitfalls of this technique have not been fully elucidated. The objective of this study is to determine the accuracy of emergency medicine resident-performed two-point compression ultrasound, and to determine what technical errors are commonly made by novice ultrasonographers using this technique. Methods: This was a prospective diagnostic test assessment of a convenience sample of adult emergency department (ED patients suspected of having a lower extremity DVT. After brief training on the technique, residents performed two-point compression ultrasounds on enrolled patients. Subsequently a radiology department ultrasound was performed and used as the gold standard. Residents were instructed to save videos of their ultrasounds for technical analysis. Results: Overall, 288 two-point compression ultrasound studies were performed. There were 28 cases that were deemed to be positive for DVT by radiology ultrasound. Among these 28, 16 were identified by the residents with two-point compression. Among the 260 cases deemed to be negative for DVT by radiology ultrasound, 10 were thought to be positive by the residents using two-point compression. This led to a sensitivity of 57.1% (95% CI [38.8-75.5] and a specificity of 96.1% (95% CI [93.8-98.5] for resident-performed two-point compression ultrasound. This corresponds to a positive predictive value of 61.5% (95% CI [42.8-80.2] and a negative predictive value of 95.4% (95% CI [92.9-98.0]. The positive likelihood ratio is 14.9 (95% CI [7.5-29.5] and the negative likelihood ratio is 0.45 (95% CI [0.29-0.68]. Video analysis revealed that in four cases the resident did not identify a DVT because the thrombus was isolated to the superior femoral vein (SFV, which is not evaluated by two-point compression. Moreover, the video analysis revealed that the

    The authors assessed efficacy and safety of the operation of plication of deep veins of lower extremities, pelvic veins, and the inferior vena cava as a method of preventing fatal pulmonary artery thromboembolism. A total of 48 patients were operated on. Of these, 23 patients belonged to traumatological-and-orthopaedical cohort, 3 to general surgical cohort, 4 to gynaecological, and 18 to vascular cohort (isolated deep vein thrombosis). The length of the floating head of the thrombus varied from 2 to 10 cm. The presence of a floating thrombus in traumatological, surgical and gynaecological patients, regardless of the length of the floating part was an absolute indication for thrombectomy and venous plication. Vascular patients were operated on in accordance with the National Guidelines (with the length of the thrombus floating portion of not less than 4 cm). In all cases, surgical management envisaged direct and indirect thrombectomy. Plication was always performed above the level of venotomy. It was shown that thrombectomy combined with plication of major veins is a reliable and safe method of prophylaxis, being in some cases the only possible method of preventing fatal pulmonary artery thromboembolism. The operation of plication makes it possible not to cancel a scheduled surgical intervention in patients with a detected floating thrombus of major veins. The operation of thrombectomy and plication above the level of the floating head of the thrombus may be considered an operation of choice in the conditions where there is no possibility to use endovascular methods of treatment (implantation of a cava filter, endovascular catheter thrombectomy), as well as in pregnant women. Restoration of the venous lumen occurs at safe terms spontaneously, not requiring repeat surgical intervention. Simultaneous plication of the vein does not complicate the course of the postoperative period of the main surgical intervention. Thrombectomy and plication do not lead to the

    To validate the diffusion-weighted MRI (DWI) for differentiation of benign from malignant portal vein thrombosis. The Institutional Review Board approved this retrospective study and waived informed consent. A total of 59 consecutive patients (52 men and 7 women, aged 40–85 years) with grossly defined portal vein thrombus (PVT) on hepatic MRI were retrospectively analyzed. Among them, liver cirrhosis was found in 45 patients, and hepatocellular carcinoma in 47 patients. DWI was performed using b values of 50 and 800 sec/mm{sup 2} at 1.5-T unit. A thrombus was considered malignant if it enhanced on dynamic CT or MRI; otherwise, it was considered bland. There were 18 bland thrombi and 49 malignant thrombi in 59 patients, including 8 patients with simultaneous benign and malignant PVT. Mean apparent diffusion coefficients (ADCs) of benign and malignant PVTs were compared by using Mann-Whitney U test. Diagnostic accuracy was evaluated using receiver operating characteristic (ROC) curve analysis. The mean ADC ± standard deviation of bland and malignant PVT were 1.00 ± 0.39 × 10{sup -3} mm{sup 2}/sec and 0.92 ± 0.25 × 10{sup -3} mm{sup 2}/sec, respectively; without significant difference (p = 0.799). The area under ROC curve for ADC was 0.520. An ADC value of > 1.35 × 10{sup -3} mm{sup 2}/sec predicted bland PVT with a specificity of 94.6% (95% confidence interval [CI]: 84.9–98.9%) and a sensitivity of 22.2% (95% CI: 6.4–47.6%), respectively. Due to the wide range and considerable overlap of the ADCs, DWI cannot differentiate the benign from malignant thrombi efficiently.

    Portal vein thrombosis (PVT) is one of the most common complications occurring during the natural course of liver cirrhosis.Even though PVT is often asymptomatic,the worsening of liver function,an unexpected episode of gastrointestinal bleeding or ascitic decompensation may be landmarks of PVT development.Beyond these clinical manifestations,it is debated whether PVT really has an impact on liver cirrhosis natural history or rather represents only one of its consequences.Probably PVT development should not only be considered as a matter of impaired blood flow or pro-coagulation tendency.On one hand,PVT seems a consequence of the worsening in portal vein outflow due to the increased hepatic resistance in cirrhotic livers.On the other hand,vascular microthrombosis secondary to necroinflammation may cause liver ischemia and infarction,with loss of hepatic tissue (parenchymal extinction) which is replaced by fibrotic tissue.Therefore,PVT might also be considered as the overt manifestation of the liver fibrosing process evolution and anticoagulant therapy may thus have microscopic indirect effects also on the progression of liver disease.At present,a connection between PVT development and the progression of liver fibrosis/cirrhosis has not yet been demonstrated.Nevertheless,it is not clear if PVT development may worsen cirrhotic patients' outcome by itself.Some authors tried to assess liver transplant benefit in PVT cirrhotic patients but data are contrasting.In this review,we will try to answer these questions,providing a critical analysis of data reported in literature.

    Inflammatory bowel diseases are associated with an increased risk of vascular complications. The most important are arterial and venous thromboembolisms, which are considered as specific extraintestinal manifestations of inflammatory bowel diseases. Among venous thromboembolism events, portal vein thrombosis has been described in inflammatory bowel diseases. We report three cases of portal vein thrombosis occurring in patients with active inflammatory bowel disease. In two of them, hepatic ab...

    Full Text Available Superior mesenteric vein thrombosis (SMVT is a rare condition, usually caused by infections, intra-abdominal inflammatory diseases, portal hypertension, hypercoagulable states, or contraceptive therapy. Due to its vague symptomatology, SMVT is often diagnosed only after an abdominal contrast-enhanced computed tomography (CT scan. In this article, we present a case of SMVT in a patient with a history of contraceptive drug use and a recent cytomegalovirus infection. A 36-year-old female was admitted to our department with the clinical symptoms of an acute appendicitis. The patient was a smoker and had been using hormonal contraceptives for over a year. Surgery was deemed the best course of action. Before the operation, blood tests showed a mild lymphocytosis and altered liver enzyme levels, while coagulation values were normal. A contrast-enhanced CT scan revealed a complete superior mesenteric vein thrombosis without signs of bowel ischemia. Anticoagulants were immediately administered. A thrombophilia panel did not highlight any noteworthy elements. Cytomegalovirus (CMV tests resulted positive. Since CMV is a rare, but potentially significant cause or precipitating factor for thrombosis in immunocompetent hosts, all patients with an unexplained fever and seemingly spontaneous thrombosis should be screened for CMV infection.

    AIM: To characterize non-alcoholic fatty liver disease(NAFLD) presentation with esophageal varices. METHODS: We carried out a retrospective cohort study on 258 patients with esophageal varices at a single tertiary referral center. These patients underwent diagnosis of several liver diseases, including: NAFLDassociated cirrhosis, hepatitis B, hepatitis C, Wilson disease, autoimune liver diseases, and others. RESULTS: Of the 258 patients, 39% of patients exhibited esophageal varices due to NAFLD-associated cirrhosis. Of the 38(14.7%) patients developed hepatocellular carcinoma during follow-up, 52% were due to hepatitis B, 26% due to hepatitis C and 13.2% due to NAFLD. Of the 258 patients, 50.0% with NAFLD, 33.3% with hepatitis B, 26.3% with hepatitis C, and 58.3% with other diseases were alive at the end of the 5-year period with a significant difference according to the Kaplan-Meier log Rank test(P = 0.040). Portal vein thrombosis was detected in 47.5% of patients with NAFLD, in 29% of patients with hepatitis B, in 17% of patients with hepatitis C, and in 62% of patients with other related diseases(P < 0.0001). CONCLUSION: Our study showed a proportionally greater elevation in liver transplant candidacy in patients with NAFLD and portal vein thrombosis. Older patients were more prone to developing cirrhosis, hepatocellular carcinoma and a high mortality rate. However, younger patients exhibited more portal vein thrombosis and gastric varices.

    Full Text Available Abstract Introduction Splenic vein thrombosis results in localized portal hypertension called sinistral portal hypertension, which may also lead to massive upper gastrointestinal bleeding. Symptomatic sinistral portal hypertension is usually best treated by splenectomy, but interventional radiological techniques are safe and effective alternatives in the management of a massive hemorrhage, particularly in cases that have a high surgical risk. Case presentation We describe a 23-year-old Greek man with acute massive gastric variceal bleeding caused by splenic vein thrombosis due to a missing von Leiden factor, which was successfully managed with splenic arterial embolization. Conclusions Interventional radiological techniques are attractive alternatives for patients with a high surgical risk or in cases when the immediate surgical excision of the spleen is technically difficult. Additionally, surgery is not always successful because of the presence of numerous portal collaterals and adhesion. Splenic artery embolization is now emerging as a safe and effective alternative to surgery in the management of massive hemorrhage from gastric varices due to splenic vein thrombosis, which often occurs in patients with hypercoagulability.

    To determine the frequency of Factor V Leiden in cases of Deep Vein Thrombosis and Healthy controls. This case control study was performed in Armed Forces Institute of Pathology Rawalpindi, From 21(st) March to 25(th) September 2013. One hundred patients with diagnostic evidence of Deep vein thrombosis on Doppler ultrasound/Magnetic resonance imaging (MRI) scan were included in the study through non probability convenient sampling and compared with 100 matched healthy controls. DNA was extracted from the blood sample by kit method. In order to identify Factor V Leiden mutation, the polymerase chain reaction (PCR) method was utilized combined with the Amplification refractory mutation system. Data was analyzed using statistical package for social sciences (SPSS) version 17. In 100 patients of Deep Vein Thrombosis (DVT), frequency of Factor V Leiden (FVL) was 13% and it is was 2% in healthy control group. A significant association was found between FVL and DVT with odds ratio of 7.32 and with P value (P = 0.003). FVL was found to be highly prevalent among patients of DVT, Signifying strong association between the two.

    Full Text Available Cerebral vein thrombosis (CVT is an infrequent condition with a large variety of causes that can lead to serious disabilities. However, in 20% to 35% of cases, no cause is found. In this study we evaluated the hereditary (P & C Proteins, antithrombin, mutation of prothrombin G20210A and factor V Leiden, other risk factors (hyperhomocycteinemia, factor VIII, ACL-ab, APL-ab, and OCP and clinical manifestations among a population of Iranian patients with CVT. 18 women and 10 men aged 16 to 50 years with CVT were screened for inherited and acquired coagulation risk factors. No one had an abnormal ACL-ab, APL-ab or antithrombin III deficiency. One had prothrombin G20210A mutation (heterozygot (3.6%. Hyperhomocycteinemia was observed in 5 patients (17.9%. APC-R was decreased in 3 (10.7%. 2 had positive factor V Leiden mutation (heterozygot (7.1%. 17 had an increased of factor VIII (60.7. PS and PC deficiencies were each detected in two cases (7.1%. Conclusion: Our study suggests that screening for inherited thrombophilia may be an integral part in the diagnostic workup and duration of treatment in patients with CVT.

    Portal vein thrombosis (PVT) is a common complication in patients with liver cirrhosis. During liver transplantation (LT), PVT may complicate the procedure and lead to a poor prognosis. The aim of this study is to evaluate patients enrolled in the China Liver Transplant Registry, to understand the influence of PVT to the LT recipients. We collected data from patients who underwent LT and were entered into the China Liver Transplant Registry. All data of medical records and follow-up were retrospectively reviewed. The preoperative condition, duration of surgery, intraoperative blood loss, postoperative early and late PVT, and survival rates were compared between patients with PVT and those without PVT. Multivariate Cox analysis and survival analysis were used to determine the influence of PVT. A total of 20,524 cases were recruited into the study. In all, 1810 (8.82%) patients were diagnosed with preoperative PVT of various severities. All patients were followed up for an average of 30.25±33.25months (up to a maximum of 171.68months). Patients with PVT had a significantly longer operating time, more intraoperative blood loss and a higher rate of post-LT PVT (Ptransplantation centers. Copyright © 2016.

    BACKGROUND: Portal vein thrombosis (PVT) is due to many risk factors, but its pathogenesis is still not clearly understood. To identify the risk factors for PVT, we analyzed the clinical characteristics and complications associated with PVT in cir-rhotic patients. METHODS: We studied patients with liver cirrhosis who were admitted to our unit from April 2009 to December 2014. The patients were divided into the PVT and non-PVT groups, and were compared by variables including gender, age, the etiology of cirrhosis, stage of cirrhosis, complications, imaging, and treatment. RESULTS: PVT was found in 45 (9.8%) of 461 cirrhotic pa-tients admitted to our hospital. Most patients (45.9%) had hepatitis B virus (HBV)-related cirrhosis, with a similar dis-tribution of etiologies between the groups. However, there was no positive relationship between PVT and etiologies of cirrhosis. Most patients (71.5%) were in the stage of hepatic decompensation. No statistically signiifcant differences were found in complications including esophageal varices, ascites, and hepatic encephalopathy between the groups. However, there was a signiifcant positive correlation between hepatocel-lular carcinoma (HCC) and PVT (P CONCLUSIONS: The incidence of PVT was 9.8%, mainly in patients with HBV-related cirrhosis. The development of PVT was associated with the severity of liver disease and HCC.

    Full Text Available Globally Behcet%u2019s disease (BD is most frequently seen in Turkey and takes its name from the Turkish dermatologist Hulusi Behcet. Basic findings of the disease are the triad of genital ulcers, oral ulcers and uveitis. Neurological involvement in BD appears an average of 5 years after the beginning of disease, or the first appearance of the disease may be neurological findings. Sinus vein thrombosis (SVT is among neurological involvements observed in BD. However diagnosis of SVT is difficult and it is a situation that may cause disability or mortality. Our case was a 24-year old female patient with diagnosed SVT who had a diagnosis of BD from 5 years. In spite of the patient frequently applying to health services, SVT diagnosis was delayed until 15 days after the initial symptoms. BD can cause SVT and SVT may cause disability or mortality but SVT may be diagnosed late, just as in our case. Therefore we present this case to increase awareness of this disease.

    BACKGROUND Diabetic myonecrosis is an uncommon complication of long-standing poorly controlled diabetes mellitus. It presents as acute non-traumatic swelling and pain of the lower extremity, which can mimic deep vein thrombosis (DVT). The clinical course is usually self-limiting and patients respond well to supportive medical therapy. CASE REPORT A 54-year-old male with past medical history of poorly controlled diabetes mellitus type II, hyperlipidemia, gastroesophageal reflux disease (GERD), and remote history of DVT presented to our emergency department with 2-week history of progressively worsening left calf pain and swelling. On physical examination, the patient had increased warmth, edema, erythema, and tenderness in the left calf, with positive Homan's sign. A lower-extremity venous Doppler was negative for DVT. His creatinine phosphokinase (CPK) level was normal, but hemoglobin A1C was 11.0%, reflective of poor glycemic control. Magnetic resonance imaging (MRI) of the left calf revealed a focus of non-enhancement in the gastrocnemius muscle along with increased enhancement of the rest of the muscle, suggestive of diabetic myonecrosis. CONCLUSIONS Diabetic myonecrosis is a rare complication of long-standing diabetes mellitus that can often mimic DVT. Diagnosis can be made on an MRI, and treatment involves strict glycemic control along with antiplatelet therapy and non-steroidal anti-inflammatories (NSAIDs).

    Retrospective analysis of the course of pregnancy, labor and mode of anesthesia in women with portal hypertension and esophageal varices induced by portal vein thrombosis. From 2000 to 2012 seven pregnant were admitted. None had liver transplantation (Ltx), the varicose have been in the 1st stage. Each of them has been consulted by the obstetrician, transplant surgeon and anesthetist. The patient condition during pregnancy, labor and postpartum period was analyzed. Pregnancy in five cases proceeded physiologically. In one threatening miscarriage was diagnosed and treated with gestagens, two patients had tocolytic. One required variceal banding twice. In three thrombocytopenia worsened, with platelet count delivery time was 2.5 min. Time from opioid administration to birth was <4 min. All children were born in good condition, weight 10-90 percentile. Regional anesthesia is contraindicated in patients with thrombocytopenia. In patients with esophageal varices sudden increase in heart rate and blood pressure can cause hemorrhage. Patients with portal hypertension can deliver at term. It is a high-risk pregnancy. In this group it is desirable to shorten the second stage of labor or complete it by c-section under general anesthesia with remifentanyl which allows getting desired analgesia without complications in the newborn. Surveillance of pregnant with portal hypertension must include monitoring of liver function and coagulation disorders.

    Studies have confirmed an association between idiopathic deep vein thrombosis (DVT) and malignant tumors. We assessed the usefulness of routine abdominal sonography in patients with idiopathic DVT to detect malignant tumors and other relevant findings. We retrospectively analyzed abdominal sonograms and records from 135 consecutive patients with confirmed idiopathic DVT and interviewed patients and their physicians during the follow-up period (mean, 30 months). Malignancy and other clinically relevant findings determined by sonography were tabulated, and the cost of each malignancy detected by abdominal sonography in this study was calculated. Malignant tumors were found in 14 patients (10%), 7 by routine abdominal sonography, 3 by other means during hospitalization, and 4 during the follow-up period. Other clinically relevant findings detected by routine abdominal sonography were found in 33 patients (24%). The estimated cost of discovering malignancy by using screening abdominal sonography was approximately US$3,000/malignancy. Abdominal sonography was useful in detecting a variety of clinically relevant findings in addition to half of the malignant tumors found in our study.

Reported in up to 45% of patients with chronic pancreatitis, SVT may also be seen in patients with acute pancreatitis and pancreatic adenocarcinoma. It causes a localized portal hypertension called sinistral portal hypertension. Unlike those with generalized portal hypertension, patients with sinistral portal hypertension are asymptomatic and have normal liver function. Upper gastrointestinal bleeding from gastric varices is a life threatening complication of SVT. In patients with gastrointestinal bleeding secondary to esophageal or gastric varices, late-phase celiac angiography is used to determine the presence SVT.

    Objective. To evaluate the incidence of deep vein thrombosis in hospitalized Chinese medical patients and the impact of DVT prophylaxis. Methods. All cases of confirmed proximal DVT from 1 January 2005 to 31 December 2008 were reviewed retrospectively to determine the presence of risk factors and whether DVT developed: during hospitalization in medical wards or in case of readmission with a diagnosis of DVT within 14 days of discharge from a recent admission to medical wards. The impact of prophylaxis will be estimated by comparing the annual incidence of proximal DVT among medical patients hospitalized from 2005 to 2007 with that of 2008 (DVT prophylaxis commonly used). Results. From 1 January 2005 to 31 December 2008, 3938 Doppler ultrasound studies were performed for suspected DVT. Proximal DVT was diagnosed in 687 patients. The calculated incidence of proximal DVT among medical patients hospitalized for at least two days was 1.8%, 2%, and 1.7% for the year 2005, 2006, and 2007, respectively. The incidence was 1.1% for 2008 (P DVT was substantial in Chinese medical patients, and DVT prophylaxis might reduce such risk.

    Directory of Open Access Journals (Sweden)

    M Horsey

    2016-07-01

    Full Text Available A 71-year-old woman with severe right lower leg pain, edema and erythema was presented to the Emergency Department and was found to have an extensive deep vein thrombosis (DVT confirmed by ultrasound. She underwent an extensive evaluation due to her prior history of malignancy and new hypercoagulable state, but no evidence of recurrent disease was detected. Further investigation revealed pernicious anemia (PA, confirmed by the presence of a macrocytic anemia (MCV=115.8fL/red cell, Hgb=9.0g/dL, decreased serum B12 levels (56pg/mL, with resultant increased methylmalonic acid (5303nmol/L and hyperhomocysteinemia (131μmol/L, the presumed etiology of the DVT. The patient also suffered from autoimmune thyroid disease (AITD, and both antithyroglobulin and anti-intrinsic factor antibodies were detected. She responded briskly to anticoagulation with heparin and coumadin and treatment of PA with intramuscular vitamin B12 injections. Our case suggests that a DVT secondary to hyperhomocystenemia may represent the first sign of polyglandular autoimmune syndrome III-B (PAS III-B, defined as the coexistent autoimmune conditions AITD and PA. It is important to recognize this clinical entity, as patients may not only require acute treatment with vitamin B12 supplementation and prolonged anticoagulation, as in this patient, but may also harbor other autoimmune diseases.

    Patients with Glanzmann thrombasthenia fail to form large platelet thrombi due to mutations that affect the biosynthesis and/or function of the αIIbβ3 integrin. The result is a moderate to severe bleeding syndrome. We now report unusual vascular behaviour in a 55-year-old woman with classic type I disease (with no platelet αIIbβ3 expression) and a homozygous ITGA2B missense mutation (E324K) affecting the terminal β-propeller domain of αIIb. While exhibiting classic bleeding symptoms as a child, in later life this woman first developed deep vein thrombosis after a long air flight then showed vascular problems characteristic of Raynaud's phenomenon, and finally this year she presented with chest pains suggestive of coronary heart disease. Yet while coronary angiography first showed a stenosis, this was not seen on a second examination when she was diagnosed with coronary spastic angina and Prinzmetal phenomenon. It is significant that the absence of platelet aggregation with physiologic agonists had not prevented any of the above cardiovascular or vascular diseases.

    Renal vein thrombosis (RVT) in neonates is a rare condition of low mortality but significant morbidity due to renal impairment.We report the case of a male term newborn with left RVT and elevated serum factor VIII (FVIII).The main symptoms of the patient and the important clinical findings: prompt diagnosis of RVT was possible because the classic clinical presentation of macroscopic hematuria, thrombocytopenia, and palpable flank mass were present in this newborn infant.The main diagnoses: finally, the reason of RVT was established when the infant was 3 months of age: the increased level of FVIII was confirmed. We discuss the diagnosis, therapy, and outcome of the patient and compare with the literature.Therapeutics interventions: however, despite anticoagulant therapy the left kidney developed areas of scarring and then atrophy.Conclusions and outcomes: Prothrombotic defects should be considered in all patients with perinatal RVT. Elevated factor VIII as a reason of RVT in neonatal period is particularly rare. Given a poor renal outcome in children associated with elevated levels of factor VIII, consideration could be given to more aggressive antithrombotic therapy in such cases.

  12. Patient education: a tool in the outpatient management of deep vein thrombosis.

    A key to effective outpatient management of thromboembolic disease is patient education. Although highly effective for the treatment of deep vein thrombosis (DVT), antithrombotic treatment may fail as a result of inadequate patient education. The risk of hemorrhage from antithrombotic drugs is related to a number of factors including intensity of anticoagulation achieved, comorbid illness, concurrent drug therapy, and lifestyle. When patients receive inadequate antithrombotic treatment, the risk of recurrent thromboembolic events and long-term complications are substantially increased. A well-organized, structured education program enables patients to learn the necessary skills that permit complex and valuable therapies to be managed on an outpatient basis. Health care professionals who are part of an outpatient DVT treatment program should possess working knowledge of adult learning theory and instructional design. To be effective, education programs should be systematically planned, have an educationally sound structure, and attempt to meet specific objectives. In addition, they should build on patients' existing knowledge, skills, and attitudes. Periodic evaluation of the education program is important to ensure that overall goals are being adequately met and to identify areas of weakness.

    This is a retrospective study on the safety and efficacy of gamma knife radiosurgery (GKR) in treating hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT). Patients with confirmed HCC and PVTT were allocated into two groups based on the treatments they received (palliative or GKR). A total of 138 patients were included (74 in the palliative group, 64 in GKR group). No significant differences in baseline characteristics existed between the two groups. Treatment-related adverse events (AEs) were recorded and compared between groups. The majority of AEs were mild to moderate and subsided naturally or after medication. There was no AE-induced death. The influences of baseline characteristics and treatment options on patients' OS were analyzed. The median OS of patients in the palliative and GKR group were 3.0 months (95% CI: 2.719-3.281) and 6.1 months (95% CI: 4.706-7.494) respectively (p = 0.003). Multivariate analysis revealed that GKR treatment, performance status 0-1, Child A, smaller tumor diameter and monolobar distribution were significant favorable prognosticators. Subgroup analyses showed OS benefit of GKR regardless of PVTT location (main or branch of PVTT). In conclusion, GKR is well tolerated in selected HCC-PVTT patients and can confer OS benefit, which needs validation in future prospective studies. PMID:26473291

    Epidemiological studies have pointed to a correlation between the oestrogen content of oral contraceptives and the risk of deep vein thrombosis (DVT). The correlation has been strongest in studies which partially consisted of adverse drug reaction reports to the Swedish Adverse Drug Reaction Advisory Committee (SADRAC). The present study analyzes the epidemiological basis of the adverse drug reaction reports on DVT in women on oral contraceptives to SADRAC. It verifies the reported correlation between the oestrogen content of the pills and the risk of DVT but it also demonstrates that this correlation probably was secondary to differences in the diagnostic standard of DVT, to differences in reporting policies to SADRAC and to an age difference between women on low-oestrogen-pills and those on high-oestrogen pills and is thus due to bias. It is concluded that adverse drug reaction reporting on oral contraceptives has been very unreliable, for which reason it cannot support any epidemiological conclusion concerning the relative thrombogenicity of high-oestrogen pills compared with that of low-oestrogen pills.

    Full Text Available OBJECTIVE: To study the arrangement of the myocardial fiber bundles at the pulmonary venous left atrial junction in patients with pulmonary hypertension, and to discuss the pathophysiological importance of this element in the etiology of acute pulmonary edema. METHODS: We obtained 12 hearts and their pulmonary vein extremities from postmortem examinations of patients with the anatomicopathological diagnosis of acute pulmonary edema. The specimens, which had no grossly visible morphological cardiac alterations, were fixed in 10% formalin, and the muscular arrangement of the pulmonary venous left atrial junctions was analyzed. This material was then isolated, embedded in paraffin, underwent serial cutting (50 µm of thickness, and was stained with Azam's trichrome. RESULTS: We observed in our specimens that: a the myocardial fiber bundles that originate in the atrial wall and involve the openings of the pulmonary veins were fewer than those observed in healthy material; b the myocardial fiber bundles that extend into the pulmonary veins were shorter than those found in material originating from individuals with no pulmonary hypertension. CONCLUSION: Anatomical changes that result in a reduction in the amount of myocardial fiber bundles in the pulmonary venous left atrial junction, isolated or associated with other factors, may be the cause of disorders in pulmonary circulation, leading to an increase in pulmonary venous pressure, and, consequently, to acute pulmonary edema.

    Full Text Available Splanchnic vein thrombosis (SVT may be negatively associated with the prognosis of pancreatitis. We performed a systematic review and meta-analysis of literatures to explore the prevalence of SVT in pancreatitis. All observational studies regarding the prevalence of SVT in pancreatitis were identified via PubMed and EMBASE databases. The prevalence of SVT was pooled in the total of patients with pancreatitis. And it was also pooled in the subgroup analyses according to the stage and causes of pancreatitis, location of SVT, and regions where the studies were performed. After the review of 714 studies, 44 studies fulfilled the inclusion criteria. Meta-analyses showed a pooled prevalence of SVT of 13.6% in pancreatitis. According to the stage of pancreatitis, the pooled prevalence of SVT was 16.6% and 11.6% in patients with acute and chronic pancreatitis, respectively. According to the causes of pancreatitis, the pooled prevalence of SVT was 12.2% and 14.6% in patients with hereditary and autoimmune pancreatitis. According to the location of SVT, the pooled prevalence of portal vein, splenic vein, and mesenteric vein thrombosis was 6.2%, 11.2%, and 2.7% in pancreatitis. The prevalence of SVT in pancreatitis was 16.9%, 11.5%, and 8.5% in Europe, America, and Asia, respectively.

    We aimed to define the possible risk factors for acute and remote seizures in patients with cerebral vein and sinus thrombosis (CVST). Ninety-four patients were recruited prospectively at Al-Zahra Hospital, Isfahan, Iran, between April 2007 and April 2012. To identify seizure predictors, we compared demographic, clinical and imaging factors between patients with or without acute and remote seizures. Of the 94 patients, 32 (34%) experienced at least one seizure after CVST development. Bivariate analysis showed a significant association of remote seizure with loss of consciousness at presentation (P=0.05, OR: 5.11, 95%CI: 1.07-24.30), supratentorial lesions (P=0.02, OR: 9.04, 95%CI: 1.04-78.55), lesions in the occipital lobe (P=0.00, OR: 12.75, 95%CI: 2.28-71.16), lesions in the temporal and parietal lobes, thrombophilia (P=0.03, OR: 5.87, 95%CI: 1.21-28.39), seizure in the acute phase (P=0.00, OR: 13.14, 95%CI: 2.54-201.2) and sigmoid sinus thrombosis (P=0.00, OR: 12.5, 95%CI: 2.23-69.79). Seizures in the acute phase were also more common in patients with paresis (P=0.00, OR: 4.88, 95%CI: 1.91-12.46), hemorrhagic lesions indicated by imaging (P=0.02, OR: 2.77, 95%CI: 1.08-7.10), supratentorial lesions, lesions in the frontal (P=0.01, OR: 3.81, 95%CI: 1.28-11.31) and parietal lobes (P=0.00, OR: 5.16, 95%CI: 2-13.29), thrombophilia and history of miscarriage (P=0.03, OR: 2.91, 95%CI: 1.07-7.91). No factor predicted acute or remote seizure in a multiple logistic regression analysis. Our results demonstrate that seizure development in the acute phase is the most significant factor for development of remote seizure. Parenchymal lesions in the supratentorial area were also found to be associated with both acute and remote seizures. However, no factor was predictive of acute or remote seizures in a multivariate analysis. Copyright © 2013 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    The effectiveness of the calf-squeeze technique during aspiration thrombectomy using guiding catheter in the treatment of an acute lower extremity deep vein thrombosis (DVT) was evaluated by the use of imaging and the clinical follow-up of patients. A prospective analysis of ten patients (seven women, three men; median age, 56.9 years) with common iliac vein (CIV) obstruction and ipsilateral DVT was performed for this study. All patients presented with leg edema or pain and were treated with catheter-directed thrombolysis via an ipsilateral popliteal vein approach after insertion of a temporary inferior vena cava (IVC) filter. Subsequently, the patients were treated with by aspiration thrombectomy using a guiding catheter to remove the residual thrombus. The calf-squeeze technique during aspiration thrombectomy can be used to induce the proximal migration of thrombi in the popliteal, tibial, and muscular veins were used to increase venous flow. The calf-squeeze technique was employed at mean of 1.3 times (range, 1-3 times). All patients showed proximal migration of a popliteal and muscular vein thrombus during the execution of the calf-squeeze technique. Successful recanalization was achieved in all patients (100%) without any complications. On duplex ultrasonography, which was performed immediately after the aspiration thrombectomy, four patients had a residual thrombus in the soleal muscular veins. However, none of the patients had a thrombus in the popliteal and tibial veins; and, during follow-up, no DVT recurred in any patient. The use of the calf-squeeze technique during aspiration thrombectomy after catheter-directed thrombolysis can induce the proximal migration of thrombi in the popliotibial and muscular veins and is an effective method that can remove a thrombus in calf veins.

    The etiology and pathogenesis of portal vein thrombosis are unclear. Portal venous thrombosis presentation differs in cirrhotic and tumor-related versus non-cirrhotic and non-tumoral extrahepatic portal venous obstruction (EHPVO). Non-cirrhotic and non-tumoral EHPVO patients are young and present with well tolerated bleeding.Cirrhosis and tumor-related portal vein thrombosis patients are older and have a grim prognosis. Among the 118 patients with portal vein thrombosis, 15.3% had cirrhosis, 42.4% had liver malignancy (primary or metastatic), 6% had pancreatitis (acute or chronic), 5% had hypercoagulable state and 31.3% had idiopathy,12% had hypercoagulable state in the EHPVO group.

    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.

    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

    Patients suffering from hepatocellular carcinoma (HCC) with tumor thrombus in the portal vein generally have a poor prognosis. Portal vein tumor thrombus must be distinguished from portal vein blood thrombus, and this identification plays a very important role in management of HCC. Conventional imaging modalities have limitations in discrimination of portal vein tumor thrombus. The application of positron emission tomography (PET) with 18F-fluorodeoxyglucose (18F-FDG) for discrimination between tumor extension and blood thrombus has been reported in few cases of HCC, while portal tumor thrombosis and portal vein clot identified by 18F-FDG PET/CT in HCC patients has not been reported so far.We present two HCC cases, one with portal vein tumor thrombus and one thrombosis who were identified with 18F-FDG PET/CT. This report illustrates the complimentary value of combining the morphological and functional imaging in achieving a correct diagnosis in such clinical situations.

    The monthly incidence of deep vein thrombosis during pregnancy varies from 0.1 to 0.8 per 1000 pregnancies, depending on the study. These figures are undoubtedly an underestimation because they were determined from clinical events with no estimation of asymptomatic forms which, in general, increase the prevalence about 3-fold. Although the absolute figures are reliable, the consequences in terms of maternal mortality and post-phlebitis sequelae warrant the careful attention paid to this condition. Moreover, it should be recalled that the prevalence of superficial venous thrombosis is similar and may be associated with a risk of pulmonary embolism.

    Pulmonary vein stenosis (PVS) is a late and rare complication of pulmonary vein isolation for the treatment of atrial fibrillation. The ideal approach to the management of PVS has not yet been established, however, corrective procedures may include both surgical and percutaneous techniques. We describe the case of a complex bifurcation lesion involving the left superior pulmonary vein. The condition required percutaneous intervention using a modified kissing stent technique with bare metal stents that resulted in an excellent post-operative course, sustained symptomatic relief, and uncomplicated 1-year follow-up. © 2014 Wiley Periodicals, Inc. © 2014 Wiley Periodicals, Inc.

    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.)

    In 1998 a 57-year-old man having skin leisons of 6 months duration reported to Central Leprosy Teaching and Research Institute (CLTRI), Chengalpattu. It was diagnosed as a case of borderline lepromatous leprosy with a type 2 lepra reaction, was treated with multi bacillary-multi drug therapy (MBMDT) for a period of 12 months and the patient was released from treatment (RFT) in September 1999. For reactions the patient was treated with prednisolone for more than 10 months. After 14 years in April 2013 the same patient presented to CLTRI with complaints of weakness of both hands with loss of sensation for 4 months, so making a diagnosis suggestive of MB relapse with neuritis the patient was started with MB-MDT for period of 12 months with initial prednisolone 25 mg OD dose then increased to 40 mg for painful swollen leg and to follow the neuritis associated pain and swelling. Increased dose is not beneficial and the patient was investigated for other pathology. Doppler ultra-sound revealed a left ileofemoral deep vein thrombosis (DVT) in that patient with levels. Prednisolone was withdrawn and the patient was started with anticoagulant heparin followed by warfarin. During this period rifampicin was also withdrawn. After patient was in good condition he was put on MB-MDT regimen. Till the 6th pulse the patient continues to show improvement in functions without steroids and any tenderness, he is taking multivitamins; regular physiotherapy. This DVT appears to be due to prednisolone and such causative relationship though rare should be kept in mind when patient on long term treatment with steroids/and or immobilized or on prolonged bed rest report with such symptomatology.

    Tumoural portal vein thrombosis (PVT) is a major prognostic factor in hepatocellular carcinoma (HCC). The efficacy of sorafenib, the only treatment approved at an advanced stage, is limited. Based on previous data, selective internal radiation therapy (SIRT), or {sup 90}Y radioembolization, seems an interesting option. We aimed to compare both treatments in this population. We retrospectively compared patients treated in two centres for HCC with tumoural PVT. We compared overall survival (OS) between patients treated with SIRT and patients treated with sorafenib. Analyses were performed before and after 1:1 matching with a propensity score for controlling indication bias, using a Cox proportional hazards model. A total of 151 patients were analysed, 34 patients treated with SIRT and 117 patients treated with sorafenib only. In the whole population, SIRT was associated with a higher median OS as compared with sorafenib: 18.8 vs 6.5 months (log-rank p < 0.001). There was an imbalance of baseline characteristics between patients treated by SIRT and sorafenib, which justified patient matching with use of a propensity score: 24 patients treated with SIRT could be matched with 24 patients treated with sorafenib. OS was estimated with a median of 26.2 vs 8.7 months in patients treated with SIRT vs sorafenib, respectively (log-rank p = 0.054). Before and after patient matching, the adjusted hazard ratio related to treatment by SIRT was estimated at 0.62 [95 % confidence interval (CI) 0.39-0.97] (p = 0.037) and 0.40 (95 % CI 0.19-0.82) (p = 0.013), respectively. SIRT seems more effective than sorafenib in patients presenting with HCC and tumoural PVT. This hypothesis is being tested in prospective randomized trials. (orig.)

    Aviation deep vein thrombosis is a challenge poorly understood in modern aviation. The aim of the present project was to determine if cabin decompression might favor formation of vascular bubbles in commercial air travelers. Thirty commercial flights were taken. Cabin pressure was noted at take-off and at every minute following, until the pressure stabilized. These time-pressure profiles were imported into the statistics program R and analyzed using the package SCUBA. Greatest pressure differentials between tissues and cabin pressures were estimated for 20, 40, 60, 80 and 120 min half-time compartments. Time to decompress ranged from 11 to 47 min. The greatest drop in cabin pressure was from 1022 to 776 mBar, equivalent to a saturated diver ascending from 2.46 msw depth. Mean pressure drop in flights >2 h duration was 193 mBar, while mean pressure drop in flights <2 h was 165 mBar. The greatest drop in pressure over 1 min was 28 mBar. Over 30 commercial flights it was found that the drop in cabin pressure was commensurate with that found to cause bubbles in man. Both the US Navy and the Royal Navy mandate far slower decompression from states of saturation, being 1.7 and 1.9 mBar/min respectively. The median overall rate of decompression found in this study was 8.5 mBar/min, five times the rate prescribed for USN saturation divers. The tissues associated with hypobaric bubble formation are likely slower than those associated with bounce diving, with 60 min a potentially useful index.

    AIM: To evaluate the efficacy of different treatment strategies for hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) and investigate factors influencing prognosis.METHODS: One hundred and seventy-nine HCC patients with macroscopic PVTT were enrolled in this study. They were divided into four groups and underwent different treatments: conservative treatment group (n = 18),chemotherapy group (n = 53), surgical resection group (n = 24) and surgical resection with postoperative chemotherapy group (n = 84). Survival rates of the patients were analyzed by the Kaplan-Meier method. A log-rank analysis was performed to identify group differences. Cox's proportional hazards model was used to analyze variables associated with survival.RESULTS: The mean survival periods of the patients in four groups were 3.6, 7.3, 10.1, and 15.1 mo respectively.There were significant differences in the survival rates among the groups. The survival rates at 0.5-, 1-, 2-, and 3-year in surgical resection with postoperative chemotherapy group were 55.8%, 39.3%, 30.4%, and 15.6% respectively, which were significantly higher than those of other groups (P<0.001). Multivariate analysis revealed that the strategy of treatment (P<0.001) and the number of chemotherapy cycles (P = 0.012) were independent survival predictors for patients with HCC and PVTT.CONCLUSION: Surgical resection of HCC and PVTT combined with postoperative chemotherapy or chemoembolization is the most effective therapeutic strategy for the patients who can tolerate operation.Multiple chemotherapeutic courses should be given postoperatively to the patients with good hepatic function reserve.

    We hypothesised that adjuvant intermittent pneumatic compression (IPC) beneath a plaster cast would reduce the risk of deep-vein thrombosis (DVT) during post-operative immobilisation of the lower limb. Of 87 patients with acute tendo Achillis (TA) rupture, 26 were prospectively randomised post-operatively after open TA repair. The treatment group (n = 14) received two weeks of IPC of the foot for at least six hours daily under a plaster cast. The control group (n = 12) had no additional treatment. At two weeks post-operatively all patients received an orthosis until follow-up at six weeks. At two and six weeks the incidence of DVT was assessed using colour duplex sonography by two ultrasonographers blinded to the treatment. Two patients withdrew from the study due to inability to tolerate IPC treatment. An interim analysis demonstrated a high incidence of DVT in both the IPC group (9 of 12, 75%) and the controls (6 of 12, 50%) (p = 0.18). No significant differences in incidence were detected at two (p = 0.33) or six weeks (p = 0.08) post-operatively. Malfunction of the IPC leading to a second plaster cast was found to correlate with an increased DVT risk at two weeks (ϕ = 0.71; p = 0.019), leading to a premature abandonment of the study. We cannot recommend adjuvant treatment with foot IPC under a plaster cast for outpatient DVT prevention during post-operative immobilisation, owing to a high incidence of DVT related to malfunctioning of this type of IPC application.

    Patients with an acute Achilles tendon rupture (ATR) take a long time to heal, have a high incidence of deep vein thrombosis (DVT) and widely variable functional outcomes. This variation in outcome may be explained by a lack of knowledge of adverse factors, and a subsequent shortage of appropriate interventions. A total of 111 patients (95 men, 16 women; mean age 40.3, standard deviation 8.4) with an acute total ATR were prospectively assessed. At one year post-operatively a uniform outcome score, Achilles Combined Outcome Score (ACOS), was obtained by combining three validated, independent, outcome measures: Achilles tendon Total Rupture Score, heel-rise height test, and limb symmetry heel-rise height. Predictors of ACOS included treatment; gender; age; smoking; body mass index; time to surgery; physical activity level pre- and post-injury; symptoms; quality of life and incidence of DVT. There were three independent variables that correlated significantly with the dichotomised outcome score (ACOS), while there was no correlation with other factors. An age of less than 40 years old was the strongest independent predictor of a good outcome one year after ATR (odds ratio (OR) 0.20, 95% confidence interval (CI) 0.08 to 0.51), followed by female gender (OR) 4.18, 95% CI 1.01 to 17.24). Notably, patients who did not have a DVT while immobilised post-operatively had a better outcome (OR 0.31, 95% CI 0.12 to 0.80). Over the age of 40 years, male gender and having a DVT while immobilised are independent negative predictors of outcome in patients with an acute ATR.

    Although anticoagulation therapy is the primary treatment for deep vein thrombosis (DVT), it has not been associated with the rapid recanalization of the venous occlusion. Moreover, it is associated with long-term disability due to post-thrombotic syndrome (PTS). In contrast, pharmacomechanical endovascular intervention (PMI) results in more rapid clinical improvement in DVT patients, but there are few reports on its long-term outcomes. This retrospective study evaluated the clinical effectiveness of PMI compared to conventional anticoagulation therapy (ACA) for acute and subacute iliofemoral DVT. We reviewed the medical records of 102 patients with iliofemoral DVT. A total of 46 patients for ACA and 56 patients for PMI were enrolled. We analyzed the clinical differences between the PMI and ACA groups by comparing the clinical signs, residual DVT free-rate, and PTS-free rate. There were no statistically significant differences in the demographic characteristics and risk factors except age between the groups (age: ACA, 52.0 ± 18.0 years; PMI, 59.0 ± 17.0 years; P = 0.035). The 1-, 3-, and 5-year residual DVT-free rate (ACA = 84.7%, 71.6%, and 46.0%; PMI = 82.1%, 76.8%, and 76.8%, respectively; P = 0.235) was not significantly different. However, the 1-, 3-, and 5-year PTS-free rate was significantly different (ACA = 93.5%, 74.0%, and 55.7%; PMI = 92.9%, 90.0%, and 90.0%, respectively; P = 0.019). There was no significant difference in the rate of other complications. PMI showed a lower incidence of PTS during the follow-up period. Therefore, PMI should be considered as an effective therapeutic modality for patients with iliofemoral DVT.

    Summary A 71-year-old woman with severe right lower leg pain, edema and erythema was presented to the Emergency Department and was found to have an extensive deep vein thrombosis (DVT) confirmed by ultrasound. She underwent an extensive evaluation due to her prior history of malignancy and new hypercoagulable state, but no evidence of recurrent disease was detected. Further investigation revealed pernicious anemia (PA), confirmed by the presence of a macrocytic anemia (MCV=115.8fL/red cell, Hgb=9.0g/dL), decreased serum B12 levels (56pg/mL), with resultant increased methylmalonic acid (5303nmol/L) and hyperhomocysteinemia (131μmol/L), the presumed etiology of the DVT. The patient also suffered from autoimmune thyroid disease (AITD), and both antithyroglobulin and anti-intrinsic factor antibodies were detected. She responded briskly to anticoagulation with heparin and coumadin and treatment of PA with intramuscular vitamin B12 injections. Our case suggests that a DVT secondary to hyperhomocystenemia may represent the first sign of polyglandular autoimmune syndrome III-B (PAS III-B), defined as the coexistent autoimmune conditions AITD and PA. It is important to recognize this clinical entity, as patients may not only require acute treatment with vitamin B12 supplementation and prolonged anticoagulation, as in this patient, but may also harbor other autoimmune diseases. Learning points A DVT can be the first physical manifestation of a polyglandular autoimmune syndrome. Hyperhomocysteinemia secondary to pernicious anemia should be considered as an etiology of an unprovoked DVT in a euthyroid patient with autoimmune thyroid disease. Patients with DVT secondary to hyperhomocysteinemia should undergo screening for the presence of co-existent autoimmune diseases in addition to treatment with B12 supplementation and anticoagulation to prevent recurrent thromboembolism.

    We sought to evaluate the clinical outcomes of 3-dimensional conformal radiation therapy (3D-CRT) for portal vein tumor thrombosis (PVTT) alone in patients with advanced hepatocellular carcinoma. We retrospectively analyzed data on 46 patients who received 3D-CRT for PVTT alone between June 2002 and December 2011. Response was evaluated following the Response Evaluation Criteria in Solid Tumors. Prognostic factors and 1-year survival rates were compared between responders and non-responders. Thirty-seven patients (80.4%) had category B Child-Pugh scores. The Eastern Cooperative Oncology Group performance status score was 2 in 20 patients. Thirty patients (65.2%) had main or bilateral PVTT. The median irradiation dose was 50 Gy (range, 35 to 60 Gy) and the daily median dose was 2 Gy (range, 2.0 to 2.5 Gy). PVTT response was classified as complete response in 3 patients (6.5%), partial response in 12 (26.1%), stable disease in 19 (41.3%), and progressive disease in 12 (26.1%). There were 2 cases of grade 3 toxicities during or 3 months after radiotherapy. Twelve patients in the responder group (15 patients) received at least 50 Gy irradiation, but about 84% of patients in the non-responder group received less than 50 Gy. The 1-year survival rate was 66.8% in responders and 27.4% in non-responders constituting a statistically significant difference (p = 0.008). Conformal radiotherapy for PVTT alone could be chosen as a palliative treatment modality in patients with unfavorable conditions (liver, patient, or tumor factors). However, more than 50 Gy of radiation may be required.

    The aim of this study is to compare the clinical outcomes of transjugular intrahepatic portosystemic shunt (TIPS) and endoscopic band ligation (EBL) in patients with cirrhosis and portal vein thrombosis (PVT). We retrospectively reviewed the January to September 2010 data from our database and included 25 patients with cirrhosis and PVT who underwent successful TIPS creation. We selected another 25 patients who underwent EBL matching for age, sex, and Child-Pugh-Turcotte class. The outcome measures included changes in the PVT status before and after the treatments, the rebleeding rate, and the overall survival. The mean follow-up was 25.1 ± 8.7 months in the EBL group and 25.6 ± 8.5 months in the TIPS group (P = 0.85). After treatments, the PVT severity improved in 40% and worsened in 25% of patients who did not undergo TIPS, compared with 87% and none of the patients who underwent TIPS (P EBL group, and 12.5% and 25.2% in the TIPS group (P = 0.002). The 1- and 2-year survival rates were, respectively, 95.7% and 85.2% in the EBL group, and 96% and 78.7% in the TIPS group (P = 0.203). The MELD score was the only independent predictive factor for survival (HR 1.73, 95% CI 1.27-2.37, P = 0.001). Compared with EBL, TIPS contributed to PVT improvement and reduced the risk of rebleeding without providing a survival benefit for patients with PVT.

    Full Text Available The prognosis of patients with advanced hepatocellular carcinoma (HCC is very poor. The outcome of these patients is particularly bleak when the disease is complicated by portal vein tumor thrombosis (PVTT, since the increased portal pressure often causes serious gastrointestinal bleedings. Before the introduction of sorafenib (SOR, a tyrosine kinase inhibitor, no effective treatment was available for patients with advanced disease. SOR is now considered the standard treatment even for patients with tumor thrombosis, although the well-known interference between tyrosine kinase inhibitors and the coagulation pathway calls for caution against their use in this setting. Here, we report the case of a 74-year-old male patient with advanced HCC and PVTT treated with sunitinib (SUN, another multikinase inhibitor. During the third cycle, our patient experienced a life-threatening hematemesis with hemorrhagic shock that required intensive care treatment and SUN discontinuation. However, he completely recovered, and the PET/CT scan performed 1 year after the adverse effect demonstrated no evidence of the tumor together with portal vein recanalization. The short course of SUN causing both tumor response and gastrointestinal bleeding warrants further studies on the effectiveness of SUN in this setting as well as on the duration of treatment with multikinase inhibitors in patients with tumor thrombosis.

    We encountered a patient with hepatocellular carcinoma who had discrepant imaging findings on portal vein thrombosis with portal phase dynamic computed tomography (CT) and CT during arterial portography (CTAP). CTAP, via the superior mesenteric artery and via the splenic artery, both showed a portal perfusion defect in the right hepatic lobe, indicating portal vein thrombosis in the main trunk of the right portal vein. Portal phase dynamic CT clearly depicted portal perfusion of the same hepatic area. Transarterial chemoembolization was successfully performed, but it was associated with severe liver injury. Clinicians should be cautious about this possible discrepancy based on imaging technique. The inaccurate evaluation of portal vein thrombosis may result in inappropriate treatment selection, which can worsen patient prognosis.
