Abstract | BACKGROUND: Thrombolysis and mechanical thrombectomy have been used to treat postoperative main portal vein and superior mesenteric vein thrombosis. PURPOSE: To evaluate the safety and efficacy of balloon angioplasty and/or stent placement without thrombolysis or thrombectomy for treating such thromboses. MATERIAL AND METHODS: Fourteen patients with postoperative main portal vein or superior mesenteric vein thrombosis underwent percutaneous transhepatic balloon angioplasty and/or stent placement without thrombolysis or thrombectomy. The rates of technical and clinical success, major complications, and recurrence were evaluated retrospectively. RESULTS: Initial technical success was achieved in 13 of the 14 patients (93%). After the procedures, these 13 patients showed brisk portal inflow, without a significant amount of residual thrombus in the stented lumen or embolism. One patient was considered to be a technical failure despite showing a brisk portal inflow because 50% stenosis and partial residual thrombus remained in the stented lumen. Initial clinical success was achieved in 13 patients. One patient with technical success died of acute respiratory distress syndrome 8 days after the procedure, whereas one patient with technical failure achieved clinical success. One patient experienced acute rethrombosis 8 days after the procedure. During the median follow-up period of 16.3 months, rethrombosis occurred in six patients (43%), including one patient with acute rethrombosis. CONCLUSION: Balloon angioplasty and/or stent placement without thrombolysis or thrombectomy may be a safe and effective treatment modality for postoperative main portal vein and superior mesenteric vein thrombosis.
