Aortic replacement in aorto-occlusive disease: an observational study.

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine
• Surgical Outcomes

Background:

• Aorto-occlusive disease often necessitates surgical intervention when stent deployment is not feasible.
• Critical limb ischemia presents a significant challenge for patients unresponsive to endovascular treatments.

Purpose of the Study:

• To evaluate the efficacy and outcomes of aortic reconstruction surgery in patients experiencing critical limb ischemia.
• To assess long-term patient survival and graft patency following aortic reconstruction.

Main Methods:

• A retrospective analysis of 86 patients who underwent aortic reconstruction for critical ischemia between 1991 and 2004.
• Disease classification included Type I (aorta/iliac), Type II (external iliac), and Type III (combined).
• Mortality data was cross-verified with death certificates; clinical and radiological data were systematically collected.

Main Results:

• The 30-day mortality rate was 10.4%. One-year patient and graft survival rates were both 80%, with 73% patient survival at two years.
• Excellent symptomatic relief was reported by survivors. Early complications (7%) included thrombosis and hemorrhage; late complications (14%) involved stenosis, thrombosis, and infection.
• Four patients developed new claudication, and one required amputation due to progressive distal disease.

Conclusions:

• Aortic reconstruction provides durable symptomatic relief for most patients with extensive aorto-occlusive disease.
• Post-operative patient attrition is primarily linked to comorbid cardiovascular conditions, not graft failure after the first year.
