Fifteen-year experience of transperitoneal management of inflammatory abdominal aortic aneurysms.
OBJECTIVE
to assess the long-term outcome of patients with inflammatory abdominal aortic aneurysms.


METHODS
over a fifteen-year period 598 cases of abdominal aortic aneurysm were treated and, of these, 32 cases (5.3%) were inflammatory in nature. The diagnosis was made on preoperative (CT) computed tomography in fifteen cases. Twenty-six patients were symptomatic on presentation and ten cases were repaired on an emergency basis. Only six were repaired electively. The transabdominal transaortic approach without dissection on the nearby adherent structures was used routinely.


RESULTS
there was one postoperative death from a respiratory arrest leading to a thirty-day mortality of 3.1%. Early graft thrombosis occurred in three cases (9.3%) and all underwent successful thrombectomy. Colonic ischaemia was encountered in one patient who later developed an aortoenteric fistula. Two patients suffered a non-fatal myocardial infarction postoperatively leading to an overall morbidity of 18.7%.


CONCLUSIONS
patients with inflammatory aortic aneurysms fare worse than patients with aortic aneurysms in general. Preoperative suspicion assists in planning surgery. We believe that the transperitoneal approach with an anterolateral aortotomy and minimal dissection of adherent structures offers excellent results in dealing with this difficult group of patients.
