A 12-year experience with femorofemoral crossover grafts
Insights
Crossover femorofemoral grafts offer a durable solution for unilateral iliac artery obstruction, demonstrating long-term patency and favorable outcomes compared to alternative treatments.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
Background:
- Unilateral iliac artery obstruction presents a significant challenge in vascular surgery.
- Crossover femorofemoral grafting is a common revascularization strategy.
Purpose of the Study:
- To evaluate the long-term efficacy and safety of crossover femorofemoral grafts for unilateral iliac artery obstruction.
Main Methods:
- A retrospective analysis of 133 patients undergoing crossover femorofemoral grafting.
- Follow-up ranged from one to 12 years.
Main Results:
- Cumulative patency rates were 73.3% at five years and 63.6% at ten years.
- Early graft failure was primarily due to inadequate runoff; late failure stemmed from distal disease progression.
- Low operative morbidity and mortality (6%) were observed.
Conclusions:
- Crossover femorofemoral grafting provides a viable and effective treatment option for unilateral iliac artery obstruction.
- Long-term graft survival is influenced by runoff adequacy and progression of peripheral arterial disease.
Abstract:
One hundred thirty-three patients with unilateral iliac artery obstruction were treated with crossover femorofemoral grafts and followed up for one to 12 years. Cumulative patency was 73.3% at five years and 63.6% at ten years. There were 17 early closures with ten unsuccessful revisions and 22 late failures between three and 122 months. Inability to establish adequate runoff was the primary cause of early failure, and the progression of distal disease was the major cause of late failures. In only five cases did progressive disease of the donor artery cause failure of the graft. Operative morbidity and mortality were low (6%), and the results compare favorably with alternative methods of treating unilateral iliac artery occlusions.
