Abstract: ［Abstract］ Objective〖HTSS〗〓To investigate the clinical efficacy of superior mesenteric artery(SMA) catheter thrombolysis in the early treatment of acute superior mesenteric venous thrombosis(ASMVT).
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Six cases of ASMVT treated with SMA catheter thrombolysis were reviewed. The diagnosis, treatment and prognosis of the patients were analyzed.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓In 6 patients, except for 1 cases undergoing laparotomy for intestinal resection, the remaining treatments were successful with no obvious complications. The blood circulation rate of the mesenteric vein in the interventional treatment reached 60.0%, and the abdominal symptoms disappeared. The patients were followed up for half a year to 2 years, and 1 cases relapsed.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Interventional therapy has the advantages of less trauma, simple operation and less complications. For patients without necrosis of the ASMVT, early intervention with adequate anticoagulation may improve patient outcomes considerably.
