Antegrade Visceral Revascularisation via a Thoracoabdominal Approach for Chronic Mesenteric Ischaemia

Abstract 

Objectivesit has been suggested that patients with chronic visceral ischaemia are elderly and emaciated hence they may not tolerate antegrade visceral revascularisation via a thoracoabdominal approach. There are no studies to support this assumption. The purpose of this study is to assess the efficacy of this approach for the treatment of chronic visceral ischaemia.Methodsbetween 1988 and 1996, 10 patients underwent antegrade visceral revascularisation for chronic visceral ischaemia via a thoracoabdominal approach and were followed-up for a mean of 40 months. Eight patients were treated with aorto superior mesenteric artery bypass and implantation of the coeliac axis in the graft and two patients with aorto superior mesenteric bypass alone. Graft patency was monitored with duplex scanning.Resultsthere were no postoperative deaths in this series. Two patients developed postoperative pulmonary infections and required intubation for a short period of time. All patients were discharged after a mean of 17 days (range 7–38). Follow up with duplex scanning revealed that all grafts were patent. One patient developed a high grade anastomotic stenosis which was followed by recurrence of the symptoms. This was dilated on three occasions by balloon angioplasty within a period of 17 months. On the last occasion a stent was placed and since then the patient remains asymptomatic.Conclusionsantegrade visceral revascularisation via a thoracoabdominal approach is a durable and effective method of relieving symptoms of chronic visceral ischaemia. The low morbidity in this series justifies larger studies in order to establish the true incidence of complications.
