【摘要】 目的 经尸体骶前静脉丛（Ｐｒｅｓａｃｒａｌ Ｖｅｎｏｕｓ Ｐｌｅｘｕｓ，ＰＳＶＰ）注水实验研究，探索ＰＳＶＰ大出血的防治措施。方法采用与血管走行方向垂直缝扎ＰＳＶＰ断裂各端、网膜填塞、压迫骶椎体静脉开口或人为通道，并缝扎在骶前纵韧带上堵水。将自来水注入ＰＳＶＰ和椎体静脉内或人为通道内。观察水从缝扎处流出情况。结果 注水压强超过１０００ｍｍＨ２Ｏ，均无水自缝扎、填塞处漏出。结论 上述措施在尸体上堵水是有效的。更多还原

【Abstract】 Objective To explore the ways of the prevention and the treatment of massive bleeding of PSVP (Presacral venous plexus,PSVP). The experiment with water injected into the PSVP was studied in 20 cadavers. Methods The ruptured ends of PSVP were stitched and ligated along with the veins perpendicularly. The opening of sacral basivertebral veins and artificial passageways were filled and pressed with free omentum. They were also stitched and packed on the presacral vertical ligament to stop water. Water was injected into PSVPs and the passageways of sacral basiverteral veins and artificial ones. Water flowing from sutured area was observed. Results There was no water flowing out from sutured area even under a pressure over 1000 mmH2O. Conclusion This method was effictive in stopping water flowing out from the sutured PSVP of the cadaver.更多还原
