Between 1981 and 1984, 42 iliac venous thrombectomies were performed in 41 patients with recent iliofemoral venous thromboses. Of the 42 thromboses, 18 extended into the inferior vena cava. In 31 cases a temporary arteriovenous fistula was constructed and in 21 cases the inferior vena cava was partially interrupted. Early postoperative venography was performed in 40 of 42 thrombectomy cases. One or more late venograms were done one to four years postoperatively. None of the patients died during the hospital stay, and there were no cases of intraoperative or early postoperative pulmonary embolism. Six postoperative hematomas were evacuated. Patency of the iliac veins was maintained in 93% of cases. When performed with care venous iliac thrombectomy associated with a temporary arteriovenous fistula appears to be the appropriate treatment for iliofemoral or iliocaval thromboses less than ten days old.

Venous Stents Placed for Postthrombotic Syndrome: The Role of Inflow Disease on Patency.
J Vasc Interv Radiol

Department of Surgery, Erasmus University Medical Center, Rotterdam, The Netherlands.
Purpose: To identify the risk of deep femoral vein (DFV) and/or femoral vein (FV) inflow disease on venous stent patency loss in postthrombotic syndrome (PTS).
Materials And Methods: This single-center retrospective study included limbs with iliofemoral and iliocaval stents for PTS. Single-vessel and double-vessel inflow disease were defined on the basis of imaging of possible postthrombotic changes in the DFV/FV.
Major Complications of Deep Venous Stenting.

Introduction: Deep venous stent placement has developed into a primary treatment modality for venous obstruction in recent decades. Reported rates of complications are low in the literature and are based mainly on case reports and single-centre cohorts. Interventionalists performing these procedures must be aware of the occurrence of complications associated with stent placement to counsel patients adequately and promote avoidance through optimal procedural approach.

Inferior vena cava (IVC) compression secondary to mass effect is accompanied by edema, ascites, back and abdominal pain, and central nervous system symptoms. Most IVC syndrome cases described in the literature focus on the focal treatment of IVC lesions, and reports of complete iliocaval reconstructions secondary to malignant IVC syndrome in the palliative context are limited. In this case report, we describe the clinical presentation, technical approach, and symptomatic outcomes of a patient with extensive malignant compression and invasion of the iliofemoral venous system.

Testicular seminoma is rarely associated with occlusive venous thrombosis. Several investigators describe percutaneous guidewire recanalization for iliofemoral vein thrombosis; however, this technique is ill-documented for occlusion of the inferior vena cava, and even less information is available on managing pervasive iliocaval obstruction. Furthermore, there is limited data on percutaneous mechanical thrombectomy for malignancy-induced venous thrombosis.

Background: B-type natriuretic peptides (BNP) and cardiac enzymes are both recognized biomarkers of heart health. Many studies have reported that using these indicators can assess cardiac condition and predict prognosis of patients undergoing surgery. Currently little is known on the effect of increased cardiac input after venous recanalization on cardiac physiology in patients with chronic venous obstruction (CVO).
