A STUDY OF ANOMALOUS ORIGIN OF OVARIAN ARTERIES AND ITS CLINICAL SIGNIFICANCE IN HUMAN CADAVERS

Background: The Gonadal Arteries most commonly arise from the abdominal aorta at the level of the second lumbar (L2) vertebra, supplying the testes and ovaries. The gonadal arteries variations are commonly seen in males on right side however there are few instances where there is variation in ovarian arteries seen in females which could be of importance. Aim of the Study: To re-evaluate the origin and courses of gonadal arteries in human cadavers and explain the developmental anatomy and its clinical significance. Materials and Methods: During routine educational dissection of 24 cadavers in the Department of Anatomy, K.A.P.V. Government Medical College, Trichy, the origin and course of gonadal arteries were observed. I found the variants in 2 female cadavers aged over 60 years. Results: The present study showed variation in the origin of ovarian arteries in 2 female cadavers (8.33%) out of 24 cadavers. I observed, a rare anatomical variant of left ovarian arteries were found, originating from the left accessory renal arteries, just below and behind the left main renal vein of 60 years and 68 years old female cadavers respectively. The variants were unilateral in origin. Conclusions: The knowledge of anatomical course and variations of the ovarian artery is important for surgeons and radiologists during invasive and non-invasive arterial procedures.
