No type I or III endoleaks occurred. One type II endoleak is under observation.
Conclusions: Sm-FBSG may play an important role in the treatment of select patients with symptomatic or ruptured complex aortic aneurysms who are at prohibitive risk for open surgery and in whom endovascular repair cannot be delayed to allow implantation of a custom-made commercial device. Until an off-the-shelf fenestrated-branched device is created that does not require a prolonged waiting period, this may be the best
option to treat patients with symptomatic or ruptured complex aneurysms that are at excessively high surgical risk. (J Vasc Surg 2012;56:1535-43.)”
“Objective: Fenestrated endovascular aortic aneurysm repair (f-EVAR) of juxtarenal aneurysms requiring cannulation of the superior mesenteric artery and renal arteries is technically challenging, has a long operating
time, and requires bilateral large-caliber see more sheath insertion into the femoral arteries. Consequently, the risk of lower limb ischemia and subsequent reperfusion injury is increased. We describe the use of an adjunct temporary axillobifemoral bypass graft (TABFBG) for f-EVAR and propose that it be used as a strategy to avoid ischemia-reperfusion injury in patients anticipated as being at increased risk.
Methods: Consecutive patients from a tertiary referral center undergoing f-EVAR, between October 2008 and August 2011, were retrospectively analyzed. Patients with lower limb arterial occlusive disease and those with difficult anatomy had an adjunct TABFBG.
Results: All patients presenting with a juxtarenal aortic aneurysm were treated endovascularly, regardless Talazoparib in vivo of aneurysm anatomy and technical difficulties. There were 37 patients without TABFBG (group 1) and 27 with TABFBG (group 2). No patients required open conversion. Sex and age were not significantly
different between the groups. The median ankle-brachial pressure index was significantly higher in group 1 (P = .0001). The groups had similar median blood loss, percentage of target vessel cannulation, and median stay in the intensive therapy unit. Morbidities were similar in both groups. There were no significant differences in cardiac, renal, or respiratory complications between the groups. The 30-day mortality BAY 1895344 concentration was 10.8% (n = 4) in group 1 and 0% in group 2 (P = .046).
Conclusions: Our series has demonstrated a significant reduction in mortality (10.8% absolute risk reduction) and no increase in morbidity with the use of a TABFBG for fenestrated grafts. This is likely a result of the reduction in ischemia and ischemia-reperfusion injury in these patients. We therefore recommend the use of TABFBG in patients with proximal severe stenotic or occlusive disease and those in whom an operative time of >4 hours is predicted (typically those for whom three or more target fenestrations is planned).
