[In situ arterial allografting for aortoiliac infection].

From January 2009 to January 2013, we treated 83 patients for aortoiliac infection by resection of all infected material and in situ revascularization with an arterial allograft. Thirteen patients (15.7 %) died during the first month or before discharge. Perioperative mortality was associated with the presence of a visceral fistula: five deaths (27.8%) occurred among the 18 patients with a visceral fistula, and8 (12.3 %) among the 65 without a visceral fistula (p = 0.11). These results confirm those of our previous studies regarding the severity of aortoiliac infection, especially in patients with a visceral fistula, and endorse our in situ allografting strategy.
