Abstract

OBJECTIVE
To document our experience of the vascular anomalies or variants in paraaortic region and intend to increase vigilance among the gynecological surgeons for presence of variable vascular anomalies or variants.
METHODS
We conducted a retrospective chart review of 280 patients with various gynecologic malignancies who had undergone systemic laparotomic or laparoscopic paraaortic lymphadenectomy between November 2003 and July 2011.
RESULTS
We discovered total nine patients of vascular anomalies during the surgery. Seven patients had an accessory polar renal artery. One patient had a duplicated inferior vena cava and the other had a right paravertebral vein. There were no vascular complications such as tearing, ligation or transection.
CONCLUSION
It is not uncommon to encounter vascular anomalies in paraaortic region during the lymphadenectomy. Hence, the gynecological surgeons must be cognizant of various vascular anomalies occurring within this area to reduce the vascular accidents.
