Innocuous-looking skin scab over an arteriovenous fistula: Case report and literature review

Badri Shrestha et al. World J Nephrol. .

Abstract

Little is written on the management of an innocuous-looking skin scab over an autogenous arteriovenous fistula (AVF) used for haemodialysis. The seriousness of the underlying pathology can be under-estimated, and this may lead to early loss of the AVF, and major-life-threatening haemorrhage. We describe the management of a 78-year-old patient presenting with an innocuous-looking scab over an AVF and review the pertinent literature on this subject.

Keywords: Arteriovenous fistula; Bleeding; Duplex scan; Scab; Treatment.
