nal interventions for diagnostic and treatment procedures, such as paracentesis, peritoneal dialysis catheter procedures, tru-cut or fine needle biopsies, manipulation of laparoscopic instruments, insertion of sutures and drains, radiofrequency thermal ablation, abscess drainage, and endoscopic gastrostomy, has increased over the past two decades. Although these procedures can be performed safely, with or without imaging guiding, some complications may occur. Inferior epigastric artery (IEA) injuries are one of the major types of puncture site-related complications that occur in mid and lower abdominal percutaneous interventions. Therefore, it is crucial to be aware of anatomical variations and the exact course of the IEA to prevent any complications during percutaneous abdominal interventions. Several computed tomography (CT) studies have been published documenting the distance from the IEA to the midline, at different levels in randomized patients (1), and mapping the IEAs and their branches in selected cases (2-4). However, few multidetector CT (MDCT) studies have been performed on the general population revealing the abdominal course of an IEA and measuring its distance to the midline at different levels (5, 6). The purpose of this study was to map the inferior epigastric vessels using reconstructed two-detector computed tomography (TDCT) images and to measure distances from the IEA to the midline to determine a safe route for percutaneous abdominal interventions.
