Influence of complete revascularization on chronic mesenteric ischemia

Area of Science:

• Vascular Surgery
• Gastroenterology
• Surgical Outcomes

Background:

• Chronic intestinal ischemia management is debated.
• Complete revascularization is a controversial approach.
• Mesenteric revascularization involves complex arterial repairs.

Purpose of the Study:

• To evaluate the outcomes of mesenteric revascularization.
• To assess the impact of revascularization extent on survival and graft patency.
• To provide recommendations for surgical management of chronic intestinal ischemia.

Main Methods:

• Retrospective analysis of 58 patients undergoing mesenteric revascularization (1981-1988).
• Inclusion of 119 repaired arteries, with data on vessel involvement and concomitant procedures.
• Assessment of operative mortality, late graft failure, 5-year survival, and graft patency rates.

Main Results:

• Operative mortality was 10%, with higher mortality in patients undergoing aortic reconstruction.
• Five-year survival and graft patency were highest in patients with three-vessel disease who received complete revascularization.
• Complete revascularization showed superior outcomes (73% survival, 90% patency) compared to partial revascularization (57% survival, 54% patency) in three-vessel disease.

Conclusions:

• Complete revascularization is associated with improved graft patency and survival in chronic intestinal ischemia, particularly in three-vessel disease.
• Repair of diseased inferior mesenteric arteries should be considered when feasible.
• Concomitant aortic operations should be avoided to minimize operative risk.
