Abstract :

This article deals with the spectrum of incidence of various abdominal vascular variants, both arterial(abdominal aorta and its main anches) and venous ( inferior vena cava and IVC) that help in better delineation of pre–operative anatomy due to great variability found in the vasculature of the abdominal organs.

Identification of these variations should be included in routine scans. The preoperative knowledge of these variants has tremendous surgical significance when laparoscopic procedures or liver surgery are planned due to limited vision of the surgical field. Moreover, recognition of the aberrant vessels can also be useful in trans catheter arterial chemoembolization and radio embolization, liver or kidney transplantation as well as interventional or diagnostic procedures.

Apart from the standard evaluation of transverse sections of the vessels, a very important element of the CTA examination is the three–dimensional reconstruction performed with high resolution.
