Abstract

Objective: Endovascular abdominal aortic aneurysm (AAA) grafts are subjectto subsequent failure of endograft limbs. We sought to determine what device-related factors could be identified that might contribute to limb failure. Methods: We reviewed the records of patients who had undergone endovascular AAA repair and femorofemoral bypass grafting at a single institution. Results: Endovascular AAA repair was performed in 173 patients. There were137 bifurcated endografts and 36 aortomonoiliac grafts combined with femorofemoral bypass grafts, yielding a total population of 310 aortic graft limbs and 36 femorofemoral grafts. Thirty-nine additional patients underwent femorofemoral bypass grafting for occlusive disease. The cumulative primary patency of all endografts performed for AAA was 92% at 21 months. Secondarypatency was achieved for all failed endograft limbs. There were 24 aortic graft limb "failures" that required intervention: seven limbs underwent thrombosis requiring revision; kinked limbs requiring stenting either at the time of graft placement (17) or subsequently (7) were identified. Fully supported endograft limbs had better primary patency (97% at 18 months) than unsupported limbs (69% at 18 months, P <.001). The aortomonoiliac grafts withfemorofemoral bypass grafts tended to have better patency (97% at 18 months) than bifurcated endografts (90% at 18 months), but this did not reach statistical significance (P = .28, not significant). Femorofemoral grafts performed for occlusive disease were found to have somewhat lower patency thanthose performed for AAA (83% vs 92% at 18 months of follow-up, P = .37, not significant). Conclusions: fully supported AAA endografts provide superior endograft limb patency compared with unsupported designs. Consideration should be given to routine stenting of all unsupported endograft limbs. Aortomonoiliac grafts and bifurcated grafts provide similar results for endograft limb patency. Femorofemoral bypass grafts performed in conjunction with aortomonoiliac grafts for ABA disease provide excellent short-term patency.
