骶前出血是直肠切除术中严重并发症,手术中平均发生率为2.17% ~3.21%,死亡率为4.96% ~13.64%。由于骶前区静脉的解剖特点,造成远侧骶前区静脉的最大静水压可以达到17 ~23cmH2O,可在短时间内丢失大量静脉血。损伤骶前静脉丛或骶椎椎体静脉后表现不同的出血特点,应采取不同的方式止血。复习了多种止血措施,但预防出血仍是第一位的,熟悉骶前区的解剖结构和掌握游离直肠的技巧是预防骶前出血的关键。
Pre-sacral hemorrhage is a serious complication of rectal resection, the average incidence of surgery was 2.17% ~ 3.21%, the mortality rate was 4.96% ~ 13.64%. Due to the anatomic features of presacral veins, the maximum hydrostatic pressure of distal presacral veins can reach 17-23 cmH2O, which can result in the loss of large amounts of venous blood in a short time. Injury sacral venous plexus or sacral vertebral veins after the performance of different bleeding characteristics, should take a different approach to stop bleeding. Review of a variety of hemostatic measures, but the prevention of bleeding is still the first person familiar with the anatomy of the presacral area and grasp the skills of free rectum is the key to preventing presacral bleeding.
