Objectives. To study the specific features of the topography of the intercostal nerves in the celiac area of the anterior abdominal wall.
Methods. The floating corpses (n=88) of both sexes without any pathology of the anterior abdominal wall were studied. There were 45% of male corpses (mean age – 53,8±11,9 years) and 55% – females (51,9±13,2 years).
The topographic anatomical dissection of the intercostal nerves in the celiac area of the anterior abdominal wall with the determination of the level of their penetration into the rectus abdominis in relation to the inferior edge of the costal arch and the external edge of the rectus abdominis muscle had been performed on each corpse.
Results. In this study the intercostal nerves (1-4 pairs) had been identified in the celiac area of the anterior abdominal wall. Most often 2 pairs of intercostal nerves (71%) met in females, while no statistically significant differences were found in males. Intercostal nerves penetrated into the rectus abdominis often via their external edges (52%), more rarely – via posterior surface (39%). In males the variant of the lateral penetration of the intercostal nerves in the rectus abdominis was more common (60%), while in females no statistically significant differences were found. To reduce the risk of intraoperative trauma of the intercostal nerves, the levels of their penetration into the depth of the rectus abdominis muscle had been determined. It had been found out that the distance from the inferior edge of the costal arch on the site of the penetration of rectus abdominis by intercostal nerves was reliably higher in females. The distance from the external edge of the rectus abdominis muscle on the site of the penetration of the muscle thickness by intercostal nerves was significantly greater in males.
Conclusion. The obtained data can be used to predict the topography of the intercostal nerves in the umbilical hernias plasty.
