Abstract

Introduction: Injuries to the inferior epigastric artery (IEA) have been reported following surgical incisions in the lower abdominal wall, abdominal paracentesis, and placement of trocars in laparoscopic access sites, resulting in the formation of hematomas in the abdominal wall. This study aimed to determine its course in relation to anatomical landmarks and suggest safe areas for performing invasive procedures.

Methods: The abdominal and pelvic computed tomography images of 50 patients were analyzed. The distance between the superior and inferior epigastric vessels and the midline was determined at two levels and then correlated with each other and with the patient’s age and sex.

Results: Computed tomography successfully mapped the epigastric vessels, demonstrating that they are usually located between 4 and 8 cm from the midline.

Conclusion: Staying away from this area will establish the safe entry zone of the anterior abdominal wall.
