Purpose: The purpose of this article is to report on the effectiveness and durability of endovascular therapy for obstructive disease of the superior mesenteric artery and celiac trunk.
Patients and methods: Our retrospective study population included nine patients (five women, four men; mean age 64 years, range 34-83 years) with 15 lesions. The indication for endovascular therapy was chronic mesenteric ischemia. The technical and clinical success rates and the incidence of complications were determined. Follow-up parameters included maintained patency and sustained clinical benefit.
Results: Ten vessels were treated. The primary technical and clinical success rates were both 100% with no perioperative mortality. Major complications occurred in two patients (pseudoaneurysms). During a mean follow-up of 31 +/- 18 months (range 3-60 months), thrombosis occurred in two patients at 1 and 3 months after the procedures, respectively. Thrombosis was successfully treated by catheter-directed intraarterial thrombolysis followed by percutaneous transluminal angioplasty (PTA) (n = 1) or stenting (n = 1). At 2 and 5 years, the primary patency rate was 78%, whereas survival was estimated to be 85% and 68% at 2 and 5 years, respectively. At this follow-up, all patients had obtained relief of symptoms.
Conclusions: Our experience suggests that endovascular treatment for chronic mesenteric arterial obstructive disease is feasible, with a low incidence of complications and acceptable midterm results.
