Review of the supernumerary renal arteries by dissection method
Introduction. A thorough knowledge of the variations ofthe renal artery has grown in importance with the increasingnumbers of renal transplants. The literature indicates thatmultiple renal arteries are found in 9-76% cases. The purposeof this study was to establish the incidence and characteristicsin cadavers. Methods. The examinations were performed on39 cadavers dissected in the Department of Anatomy Facultyof Medicine University of Sarajevo. Results. The anatomicalfindings included the presence of multiple renal arteries in18 (46.15) cases. Most often the hilar and lower polar arterieswere found, while the upper polar artery was present in only5.1% cases. Conclusions. In preparation for interventions,such as live renal donation, vascular reconstruction, renovascularhypertension, or radical nephrectomy, preoperativerenal imaging is necessary and operative techniques shouldbe considered with attention to multiple renal arteries. Therecognition of multiple renal arteries is both
