Objective stent sizing criteria help avoid infolding and endoleaks during endovascular aortic bifurcation reconstruction.
This paper introduces objective criteria for stent size selection to avoid infolding and endoleaks during endovascular reconstruction of aortic bifurcations.
May aid endovascular aortic bifurcation reconstruction; leaves open need for prospective outcome validation.
Conventional revascularization of the lower extremities secondary to aortoiliac atherosclerotic vascular disease (ASVD) involves major intra-abdominal surgery with aortobifemoral bypass grafting. Complication rates are as high as 10% and perioperative mortality can be as high as 5%; therefore, careful patient selection is paramount. Endovascular aortobifemoral bypass repair with aortic bifurcation reconstruction is an emerging option in patients deemed unsuitable for conventional surgical management. Emerging techniques such as snorkel/chimney method are expanding the number of patients who can undergo endovascular repair of abdominal aortic aneurysms and/or revascularization of the lower extremities. However, until now, objective criteria for stent size selection used in these hybrid techniques have not been described.

Matteo et al. (2012) studied Aortoiliac atherosclerotic vascular disease (ASVD). Endovascular aortobifemoral bypass repair with aortic bifurcation reconstruction was evaluated. A reliable endovascular method and objective criteria for stent size selection are described to avoid infolding and endoleaks during aortic bifurcation reconstruction using stent grafts.
