Unilateral Bifid Ureter with Persistent Left Superior Vena Cava: A Cadaveric Case Report

摘要

This is a case report of unilateral bifid ureter with Double Superior Vena Cava (DSVC) which was observed during the routine dissection on a 60-year-old male cadaver. The finding is of interest due to the presence of urogenital and vascular anomalies. The case belonged to the category of incomplete double renal pelvis and ureter along with a Persistent Left Superior Vena Cava (PLSVC) with an enlarged coronary sinus and a normal Right Superior Vena Cava (RSVC). Incomplete double ureter with the angled point of junction of the two ureters creates a narrowing that can further obstruct normal flow, predisposing to uretero-ureteric reflux and associated complications such as hydronephrosis, as well as increases the possibility of ureteral injury during surgery. PLSVC is usually an insignificant finding, however, its presence makes it difficult for insertion of central venous catheter via left internal jugular vein and is important to surgeons and interventionalists.
