Advanced carotid disease in patients requiring aortic reconstruction

Area of Science:

• Vascular Surgery
• Neurology
• Cardiovascular Medicine

Background:

• Perioperative stroke is a major risk following abdominal aortic operations.
• Patients with concurrent carotid occlusive disease present complex management challenges regarding surgical timing.
• Simultaneous carotid artery endarterectomy (CEA) and abdominal aortic reconstruction (AAR) require careful sequencing to optimize outcomes.

Purpose of the Study:

• To analyze the impact of surgical sequence (CEA first vs. AAR first) on perioperative and long-term outcomes.
• To evaluate the safety and efficacy of CEA performed prior to AAR.
• To identify factors influencing survival in patients undergoing both procedures.

Main Methods:

• Retrospective review of 121 patients undergoing both CEA and AAR within one year (1979-1989).
• Patients divided into two groups: Group I (CEA first, n=99) and Group II (AAR first, n=22).
• Analysis of perioperative stroke, mortality, and long-term survival based on the order of procedures.

Main Results:

• Perioperative stroke occurred in 2% of Group I vs. 14% of Group II (p < 0.04), with all strokes happening post-AAR.
• Overall survival was significantly greater in Group I (77% at 5 years) compared to Group II (51%, p < 0.04).
• Multivariate analysis indicated CEA as the first procedure had a protective effect on survival.

Conclusions:

• Carotid artery endarterectomy (CEA) is safe when performed before abdominal aortic reconstruction (AAR).
• Performing CEA prior to AAR reduces the risk of perioperative stroke.
• This surgical sequence may improve long-term survival in selected patients requiring both interventions.
