[False prosthetic aneurysms. Evaluation of etiologic factors]

Area of Science:

• Vascular Surgery
• Biomaterials Science

Context:

• Increasing use of prosthetic materials in aortoiliac reconstructive surgery necessitates new evaluations of anastomotic aneurysms.
• A review of 503 lower extremity revascularizations (1972-1978) and analysis of 20 false aneurysms from synthetic grafts (1972-1981) were conducted.

Purpose:

• To evaluate the occurrence and etiologic factors of false aneurysms following aortoiliac reconstructive surgery.
• To compare outcomes in patients with and without false aneurysms after aorto-iliofemoral prosthesis implantation.

Summary:

• Retrospective analysis of 97 patients with aorto-iliofemoral prostheses over a 5-year follow-up identified vascular patterns below revascularization, anastomotic level, and iterative interventions as primary etiologic factors for false aneurysms.
• Extensive reconstructive procedures at the anastomosis should be avoided; however, anastomotic technique (termino-terminal vs. latero-lateral) and hypertension (HTA) did not appear to be deleterious.

Impact:

• Provides insights into managing false aneurysms after synthetic graft use in vascular surgery.
• Suggests strategies to minimize false aneurysm formation by modifying surgical approaches and focusing on specific risk factors.
