Changes in vascular anatomy following reconstructive surgery: An in vivo angiographic demonstration of the delay phenomenon and venous recanalization

Abstract

Background Although a surgical insult may substantially alter local vascular anatomy within tissues, studies that have clearly demonstrated these changes as being dynamic phenomena have not been widely reported. The current study aimed to explore the changes in abdominal wall vasculature after a surgical insult. Methods The arterial and venous anatomy of both the deep and superficial epigastric systems of the abdominal wall were explored with computed tomographic angiography (CTA) performed before and after bilateral removal of both bilateral deep and superficial inferior epigastric systems. Results Several unique anatomic findings were evident, with dilatation of both deep superior epigastr..
