title: Deep inferior epigastric perforator flap: an anatomical study of the perforators and local vascular differences.
abstract: The objective of this study was to determine precise localization and external diameter of the lower abdominal wall perforators as well as to investigate some vascularity differences between the same parts of perfusion zones II and III according to Hartrampf perfusion zones. The study was performed on 10 fresh cadavers (20 hemiabdomens) using the gelatin injection technique. All perforators were identified, and their localization and diameter were noted. Measurements were made at the level of the fascia. We noted localization and diameter of arteries on cross-sectional planes of either part of the flap. The median sum of the external diameter of all arteries in zone I was 17.01 mm. The median sum of the external diameter of all arteries in the medial 1/3 part of zone III was 4.17 mm, and in the medial 1/3 part of zone II, it was 0.96 mm. The median sum of the external diameter of all arteries in the intermediary 1/3 part of zone III was 2.16 mm, whereas in the intermediary 1/3 part of zone II, it was 0.81 mm. Significant differences were recorded between proximal and middle horizontal regions of zones II and III and between medial vertical part of zone III and medial vertical part of zone II. Anastomoses between zones I and II are considerably smaller compared with anastomoses between zones I and III. The best vascularized parts of the lower abdominal wall were perfusion zone I, then the inner 2/3 of zone III and medial 1/3 of zone II.
