Successful treatment of acute inferior vena cava and unilateral renal vein thrombosis by local infusion of recombinant tissue plasminogen activator

Renal vein thrombosis can occur as a complication of nephrotic syndrome. We present the case of a young man with nephrotic syndrome caused by minimal change disease who developed acute inferior vena cava and left renal vein thrombosis. He was treated initially with intravenous heparin. Because of the persistence of severe left flank pain and gross hematuria, local infusion of recombinant tissue plasminogen activator was tried, with resolution of thrombi and subsidence of symptoms. Functional preservation of the involved kidney is good, as indicated by Tc-99m DMSA scan (involved kidney, 47.4%; uninvolved kidney, 52.6%). Anticoagulation is usually recommended as the treatment of choice in renal vein thrombosis. We believe that in cases with critical presentations, such as bilateral involvement, extension into inferior vena cava, acute renal failure, pulmonary embolism or severe flank pain, thrombolytic therapy should be considered as a second-line treatment if good response is not obtained with heparin.     

A surgical case of acute massive pulmonary embolism associated with a giant free-floating inferior vena cava thrombus

The risk and mortality of pulmonary embolism is high in patients with free-floating inferior vena cava thrombi. We present a successful surgical case of a 70-year-old male who had acute massive pulmonary embolism associated with a giant free-floating inferior vena cava thrombus extending above the renal veins. Emergent thrombectomy of the pulmonary artery and the inferior vena cava using cardiopulmonary bypass was carried out because he was considered at high risk for fatal recurrent pulmonary embolism. Prophylactical insertion of a Greenfield filter in the inferior vena cava was added. In this report, diagnosis and treatment of inferior vena cava thrombosis is also discussed.

Bilateral renal vein and inferior vena cava thrombosis with nephrotic syndrome treated by thrombectomy: case report with 3-year followup.

A previously healthy 19-year-old woman taking anovulatory medication presented with symptoms of the nephrotic syndrome and lupus erythematosus. Diagnosis of inferior vena cava and bilateral renal vein thrombosis was made angiographically. The patient was treated successfully by thrombectomy and anticoagulation, and remains well 3 years later. Laboratory data indicate normal renal function and only mild proteinuria. This is the longest followup of a patient with this entity reported in the literature.     

Insertion of the inferior vena cava filter followed by iliofemoral venous thrombectomy for ischemic venous thrombosis

An elderly man, with ischemic venous thrombosis of the left lower extremity, underwent insertion of the inferior vena cava filter through the right internal jugular vein, followed by left iliofemoral venous thrombectomy with the Fogarty balloon catheter, both with fluoroscopic guidance. The inferior vena cava filter was inserted before venous thrombectomy to prevent pulmonary embolism from dislodged clots during the latter procedure.

The Prognosis of Renal Vein Thrombosis: A Re-evaluation of 27 Cases

Twenty-seven patients with renal vein thrombosis were retrospectivelystudied to evaluate their long-term prognosis and relevant prognosticfactors. Twenty-four patients presented with a nephrotic syndrome, and15 had renal impairment (8 acute; 7 moderate). Ten patientshad a previous history of proteinuria, and 14 of nephrotic syndrome.Renal biopsy performed in 20 patients, of whom 19 were nephrotic,showed membranous glomerulonephritis in 14, focal segmentalglomerulosclerosis in three, minimal change glomerulonephritisin two, and periarteritis nodosa in one. Renal vein thrombosiswas angiographically proven in all patients and was bilateralin 18, localised to the left renal vein in seven, and to theright in two. Thrombosis of the inferior vena cava was associatedin seven patients. Ten patients were treated by anticoagulants alone, nine by surgicalthrombectomy, seven by thrombolysis, and two did not receiveany specific treatment. One patient underwent successively thrombectomyand then thrombolysis. Eleven patients died within the first6 months, mainly from haemorrhagic complications (n = 5) orsevere sepsis (n = 2). Survivors were followed up from 6 monthsto 19 years. Nephrotic syndrome improved or even disappearedin 12 patients, and renal function did not worsen throughoutthe follow-up in any patients. The main prognostic factors were initial renal function andtype of nephropathy: patients with membranous glomerulonephritishad a significantly better renal function and a lower mortalityrate than patients with other nephropathies. Initial renal insufficiencywas significantly associated with a poor prognosis. There wasno advantage, in terms of survival, kidney function and nephroticsyndrome, of either thrombectomy or thrombolysis over anticoagulantsalone, despite two complete venous recanalisations after thrombolysis. Accordingly, patients with renal vein thrombosis from membranousglomerulonephritis should be treated by anticoagulants alone,since the long-term prognosis of this disease seems unaffectedby intercurrent renal vein thrombosis. With respects to therisk-to-benefit ratio, thrombectomy should be avoided and thrombolysisconsidered only in patients with initial acute renal failurefrom acute renal vein thrombosis.     

Early and late results of transperitoneal thrombectomy in thrombosis of the inferior vena cava]

Acute inferior vena cava thrombosis is a rare clinical feature with unknown incidence. A clear evidence about the best treatment does not exist. Especially the indications for surgical therapy and their clinical results are published only in a few reports. So the aim of this study was to take a look to our experience and make an evaluation of the combined transcaval and transfemoral venous thrombectomy. In a retrospective study of the past 12 years 19 patients with a mean age of 28.5 years, 15 women and 4 men, showing ascension of a iliofemoral clot to the vena cava were treated by transperitoneal and transfemoral thrombectomy. The mean thrombus age was 7 days, 2 patients had bilateral iliofemoral thrombosis. Simultaneously a transfemoral thrombectomy and transcaval thrombectomy were performed after exposure of the vena cava inferior via transabdominal approach. In all cases a venous patency could be achieved, 3 times a re-thrombectomy within 1 week was necessary. One intraabdominal hematoma was revised surgically. One patient died on the first postoperative day because of a fulminant lung embolism. After a mean follow-up of 6 years 3 patients did not have any symptoms of post-thrombotic sequelae, 13 had mild and only one patient moderate post-thrombotic syndrome. The combined transperitoneal and transfemoral venous thrombectomy of the vena cava inferior represents a safe and effective treatment of the acute thrombosis of the vena cava inferior. Severe post-thrombotic sequelae especially in young women may be avoided.     

Extensive operations in kidney cancer complicated by tumor thrombus invasion of the inferior vena cava]

Invasion of renal tumor into retroperitoneal major vessels with thrombosis should be characterized as local spread of renal carcinoma and a serious complication. Extensive interventions were conducted in 30 subjects out of 196 nephrectomy cases. Nephrectomy was attended by colectomy (3 cases), pancreatic resection and adrenalectomy (3 cases), resection of the liver (2 cases), one-stage lobectomy (2 cases), adrenalectomy (9 cases), resection of the uterine appendages (1 case), resection of the colon, splenectomy, opening of an intraorganic abscess. 12 patients underwent thrombectomy from the major vein via the thoracophrenoabdominal approach. Cavathrombectomy was carried out in 7 (3.6%) patients, in 3 of which vena cava inferior was resected. Removal of the thrombus from the renal vein with resection of the opening and suturing of the vena cava inferior was performed in 5 patients. The thrombus originated from the right kidney in 9, while from the left one in 3 patients treated surgically. The thrombi occupied 4-10 cm along the renal vein from its opening. The removed kidney weighted from 400 to 3200 g. One death occurred due to pulmonary embolism during the operation, one on day 5 due to cardiopulmonary insufficiency. Histological examinations of the thrombi showed them to consist of fibrin, blood elements and tumor cells within the thrombus. The thrombi grow slowly, undergo organization and vascularization. Tumor cells multiply in the thrombus. Fibrin coating restricts cancer cell free dissemination via the venous system. Cavathrombectomy is considered the only way to prolong survival for the above patients.     

Renal venous diversion: an unusual treatment for renal vein thrombosis

Renal venous thrombosis most commonly occurs in the setting of nephrotic syndrome, hypercoagulability, or dehydration. This can usually be treated with systemic anticoagulation, and the diversion is via natural draining tributaries, eg, adrenal, lumbar, or gonadal veins. Occasionally, renal venous thrombosis results from extension of a thrombotic process, such as a large renal cell carcinoma with tumor thrombus extension into the infrahepatic inferior vena cava resulting in thrombosis of the inferior vena cava and contralateral renal vein. Herein, we report a case of left renal vein thrombosis relieved by diversion through the inferior mesenteric vein.     

Aspirex机械清栓治疗创伤后急性下肢深静脉血栓形成的临床疗效

Prophylactic interruption of the inferior vena cava: immediate and long-term hemodynamic effects.

Two hundred patients were evaluated retrospectively to determine the clinical effects of prophylactic inferior vena cava (IVC) interruption in association with aortic reconstruction. No pulmonary embolism occurred in the group with IVC interruption, but embolisms did occur in seven of 68 patients who had aortic reconstruction performed without IVC interruption. In two patients, the pulmonary embolism was fatal. Postoperative incidence of deep vein thrombosis was fatal. Postoperative incidence of deep vein thrombosis was 9% in both groups. Clinical and hemodynamic effects of prophylactic IVC interruption were studied in 20 additional patients. Venous hemodynamics (maximum venous outflow, inferior vena cava pressure, and ambulatory venous pressure) showed no change following interruption in 19/20. Sixteen patients from the original group of patients with prophylactic interruption were studied hemodyamically. No pulmonary embolism was clinically evident. One new case of deep vein thrombosis was seen. Again, venous hemodynamics showed no change as a result of IVC interruption. Prophylactic IVC interruption is a safe means of decreasing the incidence of pulmonary embolism without increasing venous-related morbidity.     

Thrombectomy and surgical reconstruction for extensive iliocaval thrombosis in a patient with agenesis of the retrohepatic vena cava and atresia of the left renal vein

In 80% of the patients presenting with deep-venous thrombosis (DVT), a risk factor can be identified. An absent or hypoplastic infrarenal vena cava is a rare risk factor for DVT in young adults. In these cases, the prevalence of congenital anomalies of the inferior vena cava (IVC) is estimated at 0.5% of the general population, up to 5% in young people. The association with coagulopathy increases the risk of DVT. We report a case of a young man who presented with a massive caval and iliofemoral-popliteal thrombosis in presence of the agenesis of retrohepatic inferior vena cava and atresia of the left renal vein. Open thrombectomy and caval reconstruction with a polytetrafluoroethylene graft were performed. Surgical option with vein reconstruction was preferred to prevent new episodes of thrombosis and the risk of acute renal failure.     

Temporary inferior vena cava filter applied to 4 patients with urological disease

A temporary inferior vena cava (IVC) filter was placed in 4 patients. Patient 1 had an advanced testicular germ cell tumor with IVC tumor thrombosis, patient 2 presented with a large adrenal tumor with IVC tumor thrombosis, patient 3 was found to have deep vein thrombosis following grade 3b renal injury, and patient 4 was suffering severe SLE with renal vein thrombosis. The temporary inferior vena cava filter prevented pulmonary thromboembolism in all cases, and no adverse reaction was observed. Temporary inferior vena cava filter is safe and useful to prevent pulmonary thromboembolism associated with urological disorders.     

Long-term mortality in patients with thrombosis of the inferior vena cava, iliac and femoral veins.

OBJECTIVES: To assess the long-term mortality in patients with thrombosis of the vena cava, iliac and femoral veins. DESIGN: Registry study. MATERIALS: Between 1992 and 2000, 212 consecutive patients with acute pelvic vein thrombosis diagnosed by duplex sonography were examined by magnetic resonance imaging (MRI) to determine the most proximal extent of the thrombus. MRI revealed a thrombosis in the inferior vena cava in 46 patients (22%), in the iliac vein in 142 patients (67%), and in the femoral vein in 24 patients (11%). METHODS: The vital status of the patients was investigated in April 2004 using the Austrian National Registry and the Cause of Death Register. RESULTS: A total of 211 patients of the original 212 patients were monitored over a mean follow-up period of 91 months. Seventy-two of 211 patients (34%) had died. There was no significant difference in the long-term mortality, the survival period or the occurrence of fatal pulmonary embolism (PE) between previously diagnosed vena cava, iliac vein, or femoral vein thrombosis. CONCLUSIONS: Extension of a thrombus into the inferior caval vein in patients considered to have a pelvic vein thrombosis has no impact on long-term mortality or the development of fatal PE compared to those patients with thrombus limited to more distal veins.     

暂时性动静脉瘘在血栓消融术治疗急性深静脉血栓形成中的作用

目的评估暂时性动静脉瘘(arteriovenousfistula,AVF)在Amplatz血栓消融器(Amplatzthrombectomydevice,ATD)治疗急性深静脉血栓形成(deepvenousthrombosis,DVT)中的作用。方法76例急性DVT患者采取ATD血栓消融术治疗,其中50例患者在介入治疗的基础上辅以暂时性AVF。结果1例术后第1天死于肺栓塞。72例术后第1天患肢肿胀明显消退、疼痛缓解。2例术后第7天对侧肢体继发DVT。暂时性AVF通畅率86%(43/50)。术后随访10～42个月,随访率90.7%(68/75)。59例肿胀消失,6例轻度下肢肿胀,1例继发下腔静脉血栓形成,2例死于其他疾病。结论暂时性AVF可提高取栓后静脉的血流量和加快其血流速度,提高静脉通畅率,是ATD的一个有益的辅助手段。     

Endovascular treatment of obliterative hepatocavopathy with inferior vena cava occlusion and renal vein thrombosis

We describe the endovascular treatment of an occlusion of the inferior vena cava (IVC) due to obliterative hepatocavopathy with renal and iliac vein thrombosis. A 34-year-old man with nephrotic syndrome and hepatic dysfunction presented to the hospital after a 3-month history of lower extremity swelling with an acute deterioration in his condition. Magnetic resonance venography diagnosed a massive IVC occlusion with thrombosis of the entire IVC, iliac veins, and renal vein. He was treated with thrombolysis, and a chronic occlusion of the infrahepatic IVC was discovered. After venous stenting of the IVC and iliac veins, he dramatically improved. After 24 months, he remains symptom-free with a patent IVC and iliac veins.
