To explore the vascular structure of the deep inferior epigastric artery perforator with the four‐dimensional computed tomography (CT) angiography. 10 abdominal specimens harvested from fresh cadavers were cannulated with trocar and injected with contrast medium in the deep inferior epigastric artery at different levels. During the perfusion of the contrast medium in the flap, the flap was scanned by three‐dimensional CT (four‐dimensional defined as three dimensional CT plus time). The CT data were sent to CT workstation and the images were processed and reformatted. The deep inferior epigastric artery perforator terminates in the subdermal vascular plexus, with bifurcating superior to the Scarps fascia and under the skin. The anastomosis in the abdominal midline occurs in the subdermal vascular plexus. The zone overlying the rectus muscle in the pedicle side has the best blood supply. The four‐dimensional CT is a useful method to study the vascular structure of the deep inferior epigastric artery perforator in the superficial fascia.
