Femorofemoral Crossover Bypass Graft Has Excellent Patency When Performed with EVAR for AAA with UIOD

To compare the durability of the crossover femorofemoral bypass graft (CFFBG) in combination with aorto-uni-iliac stent graft (AUIS) for abdominal aortic aneurysm with the durability of CFFBG used in the treatment of unilateral iliac occlusive disease (UIOD).

We analyzed the clinical records of 69 patients who underwent CFFBG from 1992 until 2010. Group I consisted of 34 patients who received CFFBGs in combination with AUIS. Group II consisted of 35 patients treated with CFFBG for UIOD. The mean period of follow up was 2.7 years. Outcomes analyzed included primary graft patency, secondary graft patency, and postoperative morbidity and mortality.

There was one death in each group. Wound infection complicated 11.4% of CFFBGs performed as a sole procedure for UIOD and 5.8% of cases in combination with AUIS (P = 0.673). Primary graft patency was 96.5% and 96.5% at 2 and 5 years in group I, compared with 76.6% and 53.7% in group II (P = 0.046, 0.009). Secondary graft patency at 5 years was 100% and 92.9% for groups I and II, respectively. No variables independently influenced primary graft patency. Patients in group I experienced complications that could be linked to the bypass graft in 20.5% of cases, after long-term follow-up.

The CFFBG possesses superior long-term durability and patency when implemented in combination with aorto-uni-iliac stent grafts and does not seem to compromise the endpoint success of endovascular treatment.
