Arteriomegaly.

Abstract

Arteriomegaly describes tortuous, ectatic, irregular vessels with prolonged blood flow. Seven cases of this entity are outlined with representative case reports. The increased incidence of aneurysms, thrombosis and embolization is noted in this and other series. The possibility that tortuous vessels may be confused with aneurysms on examination is also discussed. Due to the prolongation of blood flow, adequate arteriographic evaluation may be quite difficult.
