摘　　要：骶前区位于直肠后壁与骶骨之间,内包含疏松结缔组织、骶中动脉、骶外侧血管、骶前静脉丛、骶前神经及骶前淋巴结等。了解骶前区动脉和静脉的走向及分布、骶神经的解剖及其对内脏功能的影响、骶前孔和骶椎与血管网的关系,并根据传统尸体解剖及CT血管造影(CTA)骶前血管区三维重建结果提出骶骨固定术的手术安全区的范围;对于这些结构的解剖位置和关系的深刻认识及了解对于骶前神经切除、骶前淋巴切除等手术提供了解剖学保障,对骶前手术提供了理论基础和实践指导。The presacral area is situated between the posterior wall of the rectum and the sacrum,encom?passing loose connective tissue,the middle sacral ar?tery,lateral sacral blood vessels,the presacral venous plexus,presacral nerves,and presacral lymph nodes. It is essential to comprehend the direction and distri?bution of arteries and veins within the presacral area,the anatomy of the sacral nerves and their influence on visceral function,as well as the relationship between the anterior sacral foramen,sacral vertebrae,and the vascular network. Furthermore,based on findings from traditional autopsy and CTA three-dimensional re?constructions of the presacral vascular area,it is proposed to delineate the surgical safe zone for sacral fixation. A thorough understanding of the anatomical positioning and interrelations of these structures offers an anatomical foundation for presacral nerve resection,presacral lymphadenectomy,and other surgical pro?cedures,thereby providing both a theoretical basis and practical guidance for presacral surgery.
