In situ arterial allografting for aortoiliac graft infection: a 6-year experience.
Between October 1988 and May 1994, all aortoiliac graft infections seen in the authors' service were treated by in situ arterial allografting after resection of any infected graft or tissue. Some 83 consecutive cases were treated; there were 68 isolated primary prosthetic infections (82%) and 15 aortoenteric fistulae (18%). Emergency arterial allografting was performed in five cases (6%), elective allografting in 64 cases (77%) and elective allografting after emergency palliative revascularization using a temporary prosthetic graft in 14 cases (17%). Arterial allografts were harvested from cadavers as part of a programme to retrieve multiorgan transplant tissue. Fifteen patients (18%) died either intra- or postoperatively. Three died during the operation, one from septic shock and two from uncontrollable coagulopathy. Twelve patients died in the early postoperative period, from from septic shock, two from myocardial infarction, two from pneumonia, one from a pulmonary embolism, one from an intestinal infarction, one from recurrence of a duodenal fistula and one from disruption of the native aorta at the suture line. Three patients presented with an early complication directly related to the use of the allograft. Eleven early survivors of the series died during follow-up. Among these late deaths, only one could likely be allograft-related. In four patients, the aortic segment of the allograft was mildly dilated on late computed tomography scan; three were reoperated on for disruption of the extra-abdominal segment of their allograft. All four cases were managed with simple suture of the allograft or with the use of a new allograft. Fifteen patients exhibited 19 late occlusive lesions of their allograft; 17 of these lesions had to be treated either with transluminal angioplasty or with surgery using autogenous or allograft material. In all but one case, secondary patency could be achieved through these additional procedures. Late occlusive disease was more prevalent in the femoral segment of the allograft than in the iliac or, moreover, the aortic segment. There were no late amputations in this series.
