Morphometrics of Arterial Supply for Superficial Circumflex Iliac Artery Flap in Koreans / 체질인류학회지

ABSTRACT

We studied the distribution patterns of perforating branch of superficial circumflex iliac artery for flap surgery in Korean. Fifty one thighs from 34 Korean cadavers (17 males/ 17 females) were dissected and standard points were determined as follows point of anterior superior iliac spine (A), point of pubic tubercle (B), cross point of the line AB and femoral artery (FA), cross point of the femoral artery and the sartorius muscle (FAS), beginning point of superficial circumflex iliac artery (O), and perforating point of superficial circumflex iliac artery (P). We measured the distance and the angles between the standard points. Each frequency of superficial circumflex iliac artery from femoral artery and superficial epigastric artery is 69.6% and 30.4% respectively. The mean distance between the beginning point of superficial circumflex iliac artery (O) and the point A was 7.3+/-1.3 cm and the mean distance between the point O and the point B was 5.7+/-0.6 cm. The angle from line OA to line AB was 17.9+/-8.0 degrees and The angle from line OB to the line AB was 24.9+/-5.1 degrees. The mean distance between the perforating point for superficial circumflex iliac artery (P) and the point A was 6.3+/-2.4 cm and the mean distance between the point P and the point B was 8.3+/-2.7 cm. The angle from line PA to line AB was 33.4+/-18.3 degrees and the angle from line PB to the line AB was 24.5+/-14.3 degrees. Consequently, the pattern of distribution of superficial circumflex iliac arteries, obtained in this study, will provide useful anatomical backgrounds for the superficial circumflex iliac artery flap surgery in Korean.
