Applied anatomy of the venous vascular structure in the superficial abdomen
Objective To explore the anatomy of the venous vascular structure in the superficial abdomen using the method of radiology and cadaveric anatomy. Methods Ten abdominal specimens harvested from fresh cadavers were cannulated with trocar and injected with contrast medium into the superficial inferior epigastric vein. During the perfusion of the contrast medium in the flap, the abdominal wall was scanned by three-dimensional CT (four-dimensional defined as three dimensional CT plus time). The CT data was sent to CT workstation and the images were processed and reformatted. The result was compared with that of specimen dissection after injection of blue dye from the vein. Results Originated from paraumbilical area, the superficial inferior epigastric vein coursed obliquely to great saphenous vein of femoral vein; The superficial inferior epigastric vein located longitudinally in a plane above the Scarpa's fascia, with a subcutaneous depth of 0.27~0.41; There were obvious anastomoses existing around the paraumbilical area between the superficial inferior epigastric vein and the largest vein perforator from deep inferior epigastric vein. Conclusions It is the main draining vein of the superficial anterior abdominal wall which is confirmed by its course, diameter and distribution. The knowledge of venous drainage in the superficial anterior abdomen helps to plan DIEP flap and guide flap thinning.
