Revascularization methods in chronic visceral ischemia caused by atherosclerosis

Area of Science:

• Vascular Surgery
• Gastroenterology
• Cardiovascular Disease

Background:

• Chronic visceral ischemia, often caused by atherosclerosis, presents significant surgical challenges.
• Many revascularization methods have historically high failure rates or technical difficulties.

Purpose of the Study:

• To compare various revascularization methods for chronic visceral ischemia.
• To identify effective surgical techniques for treating atherosclerosis-induced visceral ischemia.

Main Methods:

• Review of 39 operations in 35 patients with chronic visceral ischemia.
• Evaluation of multiple revascularization techniques, focusing on success and failure rates.
• Detailed assessment of antegrade aorto-celiac prosthetic grafts and transaortic endarterectomy.

Main Results:

• Most revascularization methods were abandoned due to technical issues or high failure rates.
• Antegrade aorto-celiac prosthetic grafts demonstrated success.
• Transaortic endarterectomy using a thoracoretroperitoneal approach also proved effective.

Conclusions:

• Antegrade aorto-celiac prosthetic grafts are a viable option for visceral ischemia.
• Transaortic endarterectomy offers a successful alternative for treating chronic visceral ischemia.
• These two methods overcome the limitations of previously used techniques.
