The overall features were in keeping with a diagnosis of
intimomedial mucoid degeneration.
The patient’s renal function and blood pressure improved
postoperatively. However on the third day after admission
his haemoglobin dropped and abdominal distension was
noted. A repeat CTA indicated haemorrhage around the auto-
transplanted kidney with possible leakage of the abdominal
aneurysm. The patient received an emergent hybrid repair of the
extensive thoraco-abdominal aneurysm. The procedure involved
debranching of the coeliac artery, superior mesenteric artery
(SMA) and right renal artery, with extensive stent-graft repair
using four overlapping aortic stent grafts.
Prior to the stent-grafting, the coeliac artery and SMA were
revascularised with a bifurcated prosthetic graft, using the
