Surgical treatment of chronic visceral ischemia
Insights
Surgical repair of chronic visceral ischemia using Dacron grafts effectively relieved symptoms in all patients. This revascularization technique shows promising long-term outcomes for visceral artery disease.
Area of Science:
- Vascular Surgery
- Gastroenterology
- Abdominal Surgery
Background:
- Chronic visceral ischemia significantly impacts patient quality of life.
- Operative repair is a potential treatment for visceral ischemia.
- Revascularization strategies aim to restore blood flow to abdominal organs.
Purpose of the Study:
- To describe the experience with operative repair for chronic visceral ischemia.
- To evaluate the efficacy and outcomes of revascularization using Dacron bifurcation grafts.
- To assess symptom relief and long-term survival after surgical intervention.
Main Methods:
- Retrospective review of eight patients undergoing operative repair for chronic visceral ischemia.
- Use of Dacron bifurcation grafts for revascularization of multiple visceral arteries (superior mesenteric, hepatic, or splenic arteries).
- Analysis of postoperative complications, symptom resolution, and long-term survival.
Main Results:
- All eight patients experienced relief from intestinal ischemic symptoms post-surgery.
- Four patients survived 8 to 48 months after surgery.
- One patient died postoperatively; three died of unrelated causes within 36 months.
Conclusions:
- Operative repair, particularly revascularization of multiple visceral arteries, is an effective treatment for chronic visceral ischemia.
- The described Dacron graft technique provides durable symptom relief.
- Surgical intervention can significantly improve outcomes for patients with visceral artery disease.
Abstract:
Our experience with the operative repair for chronic visceral ischemia in eight patients, including two patients without visceral ischemic symptoms, is described. We prefer revascularization of as many vessels as possible and have used a small diameter Dacron bifurcation graft directed cephalad from the infrarenal aorta to the superior mesenteric artery and hepatic or splenic artery in four patients. One patient died postoperatively of an arrhythmia. Three patients died of unrelated causes 7 to 36 months after surgery. Four patients are alive 8 to 48 months after surgery. All patients were relieved of the intestinal ischemic symptoms by surgery.
