title: [Arterial phenomenon of autonomization of vascularized island flaps reviewed by expansion of the vascular pedicle. An experimental study in the rat].
abstract: This experimental study performed in rats examined the possible vascular extensions of a periprosthetic membrane neoflap with an axial vascular pedicle towards an adjacent cutaneous angiotome. 22 Wistar rats were operated. After tattooing the superficial iliac circumflex angiotome, the adjacent epigastric pedicle was expanded. After expansion and a two-month rest period, clinical and microangiographic studies were performed. In 50% of cases, the iliac island skin flap raised on the periprosthetic membrane created by the epigastric pedicle was considered to be viable. The microangiographic results were identical. The pathophysiological mechanism is analysed in the light of the literature.
