| Popis: | 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. |
