[Digestive arterial bypass. Long-term clinical results]

Area of Science:

• Vascular Surgery
• Gastrointestinal Surgery
• Interventional Cardiology

Context:

• Analysis of 92 restorative surgery cases on visceral arteries (celiac, hepatic, superior mesenteric) between 1966-1988.
• Focus on indirect, venous, or prosthetic bypasses and reimplants, excluding other revascularization and acute ischemic cases.
• Retrospective review of 12 years of surgical experience with consistent indications and techniques.

Purpose:

• To present a detailed retrospective analysis of restorative surgery outcomes for visceral artery disease.
• Evaluate the efficacy and safety of bypass and reimplant procedures for celiac, hepatic, and superior mesenteric arteries.
• Assess long-term results and complications associated with these restorative interventions.

Summary:

• 69 patients underwent 92 restorative procedures; 31 had consecutive surgeries, with common indications including stenosis and thrombosis.
• Procedures involved single or double artery restoration, with indirect reimplantation and bypass being common for hepatic and superior mesenteric arteries.
• No perioperative deaths occurred; early thrombosis recurred in 2 patients. Long-term, 17 patients remained symptom-free, with recorded blindness and secondary deaths.

Impact:

• Demonstrates the feasibility and safety of restorative surgery for visceral artery disease, with no perioperative mortality.
• Highlights the long-term outcomes, including symptom relief in a significant portion of patients.
• Provides valuable data for refining surgical strategies and patient selection for visceral artery revascularization.
