Correlation of Pelvic Sentinel Lymph Node With Superficial Vein

Pelvic Sentinel Lymph Node (SLN) biopsy is an important integral part of endometrial surgery. Although SLN is usually found on internal iliac artery, location is variable. Lymphatic pathways in pelvis determines the location (Obturator, internal iliac or external iliac vessel locations). Since it is accepted that the lymphatic channel formation during embryologic life follows venous system formation investigators hypothesized that the presence or absence of superior or deep uterine vein may determine the location of sentinel lymph node
