Contemporary results for open repair of suprarenal and type IV thoracoabdominal aortic aneurysms

Abstract

Background: Endovascular and hybrid procedures are not yet widely established in the management of type IV thoracoabdominal aortic aneurysm (TAAA). Open surgery remains the treatment of choice until the long-term outcomes of these novel techniques are known. Methods: This study reviewed a 10-year experience of open repair of non-ruptured type IV and suprarenal TAAA. All procedures were performed using a totally abdominal approach with supracoeliac clamping of the aorta. Results: There were 53 patients (31 men; 58 per cent) of median age 69 (range 54-82) years. Forty-four patients had a type IV TAAA and nine a suprarenal aneurysm. Three patients (6 per cent) died within 30 days and the 12-month mortality rate for patients followed for at least 1 year was 6 per cent (three of 49). Ten patients (19 per cent) had a cardiac complication, 20 (38 percent) a respiratory complication, three (6 percent) required early reoperation, and one patient (2 percent) developed permanent paraplegia. There was one late death resulting from an aneurysm-related complication. Conclusion: Open repair of suprarenal aneurysms and type IV TAAA may be undertaken using a totally abdominal approach with acceptable levels of morbidity and mortality.
