Purpose. Research of features of topography of the arcuate line of the rectus sheath.            Materials and methods. There were studied 30 corpses of both sexes without signs of pathology of the anterior abdominal wall. During the autopsy of corpses, the muscular aponeurotic layer of the medial section of the anterior abdominal wall with fragments of the pubic bones, breast and costal arches was taken. On the prepared anatomical preparations was determined localization of the arcuate line of the rectus sheath in the midline relatively to the umbilical ring and the upper edge of the pubic symphysis.       Results. In this studied autopsy material the arcuate line of the rectus sheath was more located below the umbilical ring (93%), by the way part of the upper third of the segment from the lower edge of the umbilical ring and the upper edge of the pubic symphysis (50%). In females, the arcuate line of the rectus sheath relative to the umbilical ring was located more lower (5,4±0,8 cm), compared to males (3,5±0,7 cm).  Conclusion. The obtained data can be used in performing hernioplasty of variously localized hernias for the prevention of intra- incisional and incisional complications.
