Revascularizations of an island flap with a pedicle consisting of the inferior super ficial epigastric artery and vein based on different vascular states of recipient beds were observed by flap survival, peripheral neovascularization through microangiography, tissue blood flow measurement applied the hydrogen washout technique. The rats were divided into three groups: group I were the routes of revascularization from both margin and depth beds, group I only margin bed, group III only depth bed, The following conclusions were obtained: 1) Revascularizations necessary for flap survival completely were established on postoperative 4 days in group I, 8 days in group n, and 10 days in group even interrupted the passage of nutrient vessels. 2) The roles to revascularization were almost equally acted both margin bed and depth bed, and revascularization from margin recipient beds were began earlier than that from depth beds despite of the small area involved. 3) The vascular networkes of subdermal plexus were acted as the leading role of flap revasscularization. 4) The blood flow volume after postoperatively with hydrogen gas washout technique were increased by degrees, and be closely related to findings of microangiographic observation.
