P.14 Transcranial Colour Duplex Reveals Haemodynamically Significant Venous Flow Alterations Following Resection of Arteriovenous Malformation of the Brain

Abstract

Background: Resection of a brain arteriovenous malformation (bAVM) can impose several post-operative challenges including postoperative haemorrhage (POH) [1]. The mechanism of such complications remains controversial although deliberately inducing hypotension has proven successful for POH prevention [2]. Daily non-invasive monitoring for patients may be useful in predicting POH. Transcranial color duplex (TCCD) and central aortic pressures (CAP) can be derived non-invasively providing pressure and haemodynamic measurements. These techniques may provide valuable insight into the process of vessel remodeling following bAVM resection.
