盆丛的临床解剖学

Clinical Anatomy of Pelvic Plexus

作者在40侧成人男性盆腔标本上观测了盆丛的形态、位置,并以坐骨棘为基准对盆丛做了定位调查.盆丛位于直肠前外侧,紧贴脏器。根据丛的形态,可以分为集中型(占25%)和分散型(占75%).以盆丛的扇形发支处为界,测量了盆丛最大宽径为3.85±0.9cm,最大纵径为3.55±0.7cm。将最大宽径和纵径的交点作为盆丛中心点。在盆丛中心点与坐骨棘投影的正中矢状平面上,93%的盆丛中心点分布在以坐骨棘为圆心,半径为2cm的同心圆范团范围内。讨论了盆腔脏器切除术保护盆丛的有关问题。

Injury of pelvic plexus is common in pelvic visceral resection and could result in its dysfunction.In this study,the authors observed the pelvic plexus morpho-logically on 40 sides of male adult cadavers.It was found that pelvic plexus was located anterolaterally to the rectum and very closely to the pelvic organs,which could be classified into two types according to its morphology.The maximum transverse and vertical diameters were 3.85cm and 3.55cm respectively.The center of pelvic plexus in 93%of the cases was found in an area of a circle with radius of 2cm and center at ischial spine.The way to prevent the pelvic plexus from being injured during pelvic visceral resection was suggested.
