Abstract:
Objective To provide applied anatomic data for relevant operations of blood vessels of perisacral promontory(BVPSP). Methods The composition of BVPSP including origin, course, diameter of the middle sacral vessels, the distance between the sacral promontory and the sacral 1 transverse trunk were observed on 37 adult cadavers. Result The BVPSP is composed of the common and internal iliac vessels, the superior segment of the middle sacral vessels and the sacral 1 transverse trunk. Middle sacral artery comes from abdominal aorta. Middle sacral veins are thin walled without valves. The average diameter of middle sacral artery and vein is 1.02 mm and 2.53 mm respectively. The distance between the sacral 1 transverse trunk and the sacral promontory is 5.75 mm. Conclusion The composition of BVPSP, especially middle sacral veins, plentiful vascular anastomosis are the anatomical basis leading to massive hemorrhage in the relevant operations.
