Hydrogen peroxide priming of the venous architecture: A new technique that reveals the underlying anatomical basis for venous complications of DIEP, TRAM, and other abdominal flaps

Abstract

Background:: Previous studies of venous anatomy lack the detail of their arterial counterparts because of (1) the technical challenge of retrograde perfusion against competent valves and (2) anterograde venous perfusion failing to adequately delineate the area of interest. We introduced a novel technique: retrograde hydrogen peroxide priming that dilates veins and renders valves incompetent, thereby facilitating complete cadaveric venous perfusion. Methods:: The superficial and deep venous systems of 41 hemiabdomens and 20 hemichests of unembalmed human cadavers were primed by retrograde injection with 6% hydrogen peroxide. Specimens were then injected with lead oxide contrast, radiographed,..
