Abstract: Objective To conduct an empirical study for quantifying the anastomosis between two vessels after skin expanded technique by the method of angiography and to provide a precise basis for vascular study in skin flap.Methods Bilateral skin flaps based on deep iliac circumflex vessels were elevated from the abdominal wall including deep superior epigastric vessels.One was expanded at the boundary between two vessels and the other unexpanded.An X-ray image was obtained by carotid arterial injection of gelatin-lead oxide mixture.Three parallel lines with equal intervals perpendicular to long axis of the two vessels were designed at the communication area.Vessel anastomosis quantity was determined by counting the number of marks derived from the intersections of the lines and the vessels and statistical analysis was carried out.Results The marks of intersection in expanded group were more than unexpanded group with statistical significance.Conclusions The method for quantifying vessel anastomosis in skin flap is reliable.The principles of this procedure may also be applied to other experimental and elinical studies.
