ANCILLARY DETECTION OF ABDOMINAL VASCULAR VARIANTS ON MULTIDETECTOR COMPUTED TOMOGRAPHY

Dr Anagha Rajeev Joshi, Dr Priyanka Nityanand Karanje, Dr Ashwini Purshottam Sankhe, Dr Sneha Rohit Pai

Abstract


This article deals with the spectrum of incidence of various abdominal vascular variants, both arterial(abdominal aorta and its main branches) 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.
