Abstract

Background: To report a novel staged hybrid technique to treat complex juxtarenal abdominal aortic aneurysm (JAAA) associated with at least one iliac artery aneurysm (IA) with no adequate distal fixation zone.

Methods: The novel technique herein described has two main "staged" steps. The first step consists in creating an adequate distal fixation zone by endovascular means; after hypogastric embolization an iliac stent-graft has placed from 5 mm above the aortic bifurcation to the external iliac artery. The second step is the surgical resection of the JAAA and graft placement sutured distally to the stent-graft which was always performed the day after.

Results: The five cases included (mean age 74 years), were rejected for fenestrated or branched endovascular aortic repair or iliac branch devices. Four tube grafts and one aorto-bi-iliac graft were sutured to one stent-graft (N.=3), two stent-grafts in iliac kissing configuration (N.=1) and to a main body of a bifurcated stent-graft (N.=1). Mean follow-up duration was 14 (4-27) months with no mortality. Technical success was obtained in all cases (2 suprarenal clamping). Postoperative complications included two pleural effusions, two transient gluteal intermittent claudications, and one renal failure.

Conclusions: The technique herein described seems to be a feasible and cost-effective alternative treatment for selected concomitant complex JAAAs and IAs unsuitable for totally endovascular treatment.
