Variations In The Origin Of Gonadal Artery And Its Clinical Significance

Background: A sound knowledge of variations of blood vessels is required during operative, diagnostic andendovascular procedures in the abdomen and pelvis. The anatomy of the gonadal vessels has assumed moreimportance with development of newer intra-abdominal operative and laparoscopic techniques. The main aimof this study is to highlight incidence of variable origin of gonadal artery and its clinical significance.Materials and Methods: Dissection of posterior abdominal wall was done in 30 cadavers in the department ofAnatomy, K.P.C. Medical College and Hospital, Kolkata to observe the origin and course of gonadal arteries.Results: Variation was found in two cases (6.67%). Both of the cases were in male (8.33%) and on the left side.Conclusion: Various morphological anomalies of gonadal arteries are reported. The possible embryologicalbasis for this variation as well as its clinical significance, are discussed. The knowledge of this variation willhelp the radiologists and surgeons in avoiding clinical complications during uroradiologic interventions andsurgical procedures such as renal and gonadal surgeries.

Three rare variations in the course of the gonadal artery / Tres raras variaciones en el trayecto de la arteria gonadal

The gonadal arteries, lateral branches of the abdominal aorta, usually arise distal to the renal vessels. Knowledge of the origin and course of them, particularly their relationships with renal vessels, are important for uncomplicated surgical procedures on the posterior abdominal wall. So the relationship of the testicular artery and renal vessels were studied in 80 cadavers in Calcutta National Medical College, India and detected three rare variations. We have discussed the possible clinical implications and embryological explanation with review of literature of those variations.

Las arterias gonadales, ramas laterales de la aorta abdominal, usualmente surgen distales a los vasos renales. El conocimiento del origen y trayecto de estas, particularmente sus relaciones con los vasos renales, son importantes para procedimientos quirúrgicos sin complicaciones en la pared posterior del abdomen. La relación de la arteria testicular y los vasos renales fueron estudiados en 80 cadáveres en la Escuela Nacional de Medicina de Calcuta, India y se detectaron tres variaciones raras. Se discuten las posibles implicancias clínicas y explicaciones embriológicas, con la revisión de la literatura de estas variaciones.
