盆腔脏器根治术通常产生排尿、排便和性功能障碍等并发症。其原因现已公认主要是损伤了支配这些器官的神经.盆腔脏器的神经支配来自盆丛.显然减少术后功能障碍的发生率,术中保护盆从是个关键.本文就有关这方面的问题分述如下: 一、盆丛的解剖概况盆丛亦称下腹下丛,由植物性神经组成. (一)盆丛的来源组成:盆丛由腹下神经盆内脏神经和骶交感干支交织而成. 1.上腹下丛和腹下神经:上腹下丛位于腹主动脉叉下方、髂总动脉之间区域内,其形态呈网状。少数仅由数支纵行纤维所组成.在骶骨岬平面上或下方,上腹下丛分叉成为左右腹下神经.腹下神经可以是单干.但更多见由2~3支纤维组成,并以横支吻合成丛.约在第三骶椎水平,腹下神经下端纤维分散,构成盆丛.在小骨盆入口缘以上,腹下神经与髂总血管行走方向一致且位于髂总血管内侧.在小骨盆入口缘,腹下神经与
Pelvic organ radical surgery usually produces complications such as urination, defecation and sexual dysfunction. The reason is now recognized mainly to damage the nerves that dominate these organs.The pelvic organs of the innervation of the pelvic plexus.Obviously reduce the incidence of postoperative dysfunction and intraoperative protection of the basin is a key.This article on this issue As follows: First, the anatomy of the basin plexus plexus, also known as the lower abdomen plexus, composed of autonomic nerve. (A) the origin of the basin plexus: pelvic plexus by the inferior pelvic nerve and sacral sympathetic stem interwoven 1. Abdominal celiac plexus and hypogastric nerve: The abdomen plexus is located below the aorta of the abdominal aorta, with a reticular shape in the area between the common iliac arteries. Only a few by a few longitudinal fibers composed of sacral headland in the plane or below, the upper and lower celiac plexus bifurcation into the right and left inferior hypoglossal nerve can be single .Normally seen by 2 to 3 fibers, And horizontal cross-kiss synthesis of plexus.About the third sacral level, the lower hypogastric fibers scattered to form the basin plexus in the pelvis basin above the entrance edge, the inferior ileus nerve and common iliac artery walking in the same direction and located in the common iliac vessels At the entrance to the pelvis, the hypogastric nerve interacts with
