Reoperation for recurrent chronic visceral ischemia

Area of Science:

• Vascular Surgery
• Gastrointestinal Surgery
• Interventional Cardiology

Background:

• Recurrent visceral ischemia affects up to one-third of patients post-revascularization.
• Management strategies for recurrent visceral ischemia remain incompletely described.
• This study addresses the clinical presentation, surgical management, and outcomes of recurrent visceral ischemia.

Purpose of the Study:

• To analyze the presentation of recurrent visceral ischemia.
• To evaluate the surgical management of recurrent visceral ischemia.
• To determine the outcomes, including survival rates, following reoperation for recurrent visceral ischemia.

Main Methods:

• A retrospective review of 109 patients undergoing primary visceral revascularization between 1959 and 1997.
• Analysis of 24 patients who underwent 30 reoperations for recurrent visceral ischemia (12 chronic, 7 acute).
• Symptom-free and overall survival rates were calculated using life table analysis.

Main Results:

• Recurrent acute visceral ischemia had a high mortality rate (85.7%).
• Reoperation for chronic recurrent visceral ischemia involved antegrade aortovisceral bypass or transaortic visceral endarterectomy.
• First reoperations had a 6.7% mortality and 33.3% complication rate, with 77.3% symptom-free survival at 1 year.

Conclusions:

• Recurrent visceral ischemia is a frequent complication of primary visceral revascularization.
• Reoperation for recurrent chronic visceral ischemia is safe and effective.
• Repeat visceral revascularization provides durable symptom relief and comparable life expectancy to primary procedures.
