Outcome of Elective and Emergency Open Thoraco-Abdominal Aortic Aneurysm Repair in 255 Cases: a Retrospective Single Centre Study

Published:March 18, 2022DOI:


      This study reports on open TAAA repair comparing short and long term patient outcome according to the type of repair defined by the Crawford classification and elective vs. emergency repair. Endpoints were death, acute kidney injury (AKI), sepsis, spinal cord ischaemia (SCI), and re-intervention rate.


      This was a retrospective study reporting the outcomes of 255 patients (between 2006 and 2019), designed according to the STROBE criteria.


      The TAAA distribution was type I 25%, type II 26%, type III 23%, type IV 18%, and type V 7%. Fifty-one (20%) patients had an emergency procedure. Of all the patients, 51% had a history of aortic surgery, 58% suffered from post-dissection TAAA, and 26% had connective tissue disease. The in hospital mortality rate among electively treated patients was 16% (n = 33) vs. 35% (n = 18) in the emergency subgroup; the total mortality rate was 20% (n = 51). The adjusted odds ratio for in hospital death following emergency repair compared with elective repair was 2.52 (95% confidence interval [CI] 1.15 – 5.48). Temporary renal replacement therapy because of AKI was required in 29% (n = 74) of all patients, sepsis from different cause was observed in 37% (n = 94), and SCI in 7% (n = 18, 10 patients suffering from paraplegia and eight from paraparesis). The mean follow up time was 3.0 years (median 1.5, range 0 – 12.8 years). Aortic related re-intervention was required in 2.8%. The total mortality rate during follow up was 22.5% (n = 46); 5.3% (n = 11) of all patients died because of aortic related events.


      Open TAAA repair is associated with an important morbidity and mortality rate, yet the incidence of spinal cord ischaemia may be favourably low if a neuromonitoring protocol is applied. The aortic related re-intervention and aortic related mortality rate during follow up are low.
