Controlled hypotension for cerebral aneurysm surgery in the presence of severe aortic coarctation
1Brain Dwyer Department of Anaesthetics, St Vincents Hospital, Darlinghurst NSW, Australia.
A patient is described with a bicuspid aortic valve and an undiagnosed aortic coarctation, presenting with a subarachnoid haemorrhage. A cerebral aneurysm was clipped under controlled hypotension. In view of the risk of inducing severe hypotension in the distal aorta in this patient, femoral arterial pressure was monitored. A marked reduction in the radial-femoral arterial pressure gradient during controlled hypotension was noted.
