Abstract
OBJECTIVES: To evaluate the possible prevention of renal and intestinal ischaemia during surgery of thoracoabdominal aortic aneurysms (TAAA) by use of retrograde and selective organ perfusion. DESIGN: Prospective study. MATERIALS: Thirty-three consecutive patients underwent TAAA repair, six of whom had a previous type B dissection: 14 patients (35%) had type I TAAA, 12 patients type II (32%), three patients type III (15%) and four patients type IV (18%). Mean age was 61 years (range 22-84 years). METHODS: In patients with type I TAAA, retrograde aortic perfusion was performed by means of a left atrium femoral artery bypass or partial cardiopulmonary bypass. In type II, III and IV the same procedure was performed; however, following cross-clamping and opening of the abdominal aorta, the coeliac trunc, superior mesenteric and both renal arteries were selectively perfused with four Pruitt-catheters (9 Fr.), connected as an octopus to the extracorporal circulation. RESULTS: All patients survived the surgical procedure. The minimal volume flow through each octopus catheter was 60 ml/min. Urine output was uninterrupted in all patients, irrespective of the aortic cross-clamp time. Only one patient (3%), who already had renal insufficiency, developed renal failure. Total in-hospital mortality was 15%, paraplegia occurred in 12%. CONCLUSION: Retrograde aortic and selective organ perfusion is a safe technique and can prevent ischaemic renal and intestinal damage during cross-clamping of the aorta in thoracoabdominal aneurysm surgery
