[Vascular anomalies: obstacles in ureteral dissection in centripetal radical surgery for uterine cancer].

Vascular abnormalities may create difficulties during exposure of the lateral surface of the ureter during radical lymphadeno-hystero-colpectomy for uterine carcinoma. The aim is to avoid peroperative bleeding due to damage to abnormal vessels (in particular abnormal anastomotic uterine vein) crossing the lateral surface of the ureter. The authors have encountered such vascular abnormalities three times during radical lymphadeno-hystero-colpectomy. Recognition of the abnormal vessel crossing the lateral surface of the ureter and its division between two separate sutures prevented accidental peroperative bleeding as well as possible damage to the terminal (juxta-vesical) part of the ureter.
