摘　　要：以多层螺旋CT （MDCT）扫描及三维重建为研究手段，探讨急性胰腺炎成人肾筋膜向下的附着关系、肾周间隙向下的通连关系，以及CT对其的诊断价值。收集2012年5月~7月于我院行全腹CT增强扫描检查的急性胰腺炎82例的CT资料，采用三维重建，观察肾筋膜向下的附着情况及肾周间隙向下的通连关系。结果发现：（1）肾筋膜前后层在髂窝平面附近融合：左侧占71.95%（59/82），右侧占75.61%（62/82），左右肾周间隙、肾旁前后间隙在下方均不通连。（2）肾筋膜前后层在肾脏下方不融合：左侧占28.05%（23/82），右侧占24.39%（20/82），左右肾周间隙向下可延伸至盆腔腹膜后间隙及腹股沟深面，肾旁前后间隙在下方仍不通连。研究显示MDCT增强扫描三维重建能判断肾筋膜向下的附着情况，以及肾周间隙向下的通连关系。This study aims to explore the inferior adhesion of the renal fascia （RF）, and the inferior connectivity of the perirenal spaces （PS） with multidetector computed tomography （MDCT）, and to investigate the diagnostic value of CT for showing this anatomy. From May to July 2012, eighty-two patients with acute pancreatitis presented in our hospital were enrolled into this study and underwent contrast-enhanced CT scans. All the image data were used to perform three dimensional reconstruction to show the inferior attachment of RF and the inferior connectivity of PS. The fusion of anterior renal fascia （ARF） and posterior renal fascia （PRF） next to the plane of iliac fossa were found on the left in 71.95% （59/82） cases, and on the right in 75.61% （62/82）. In these cases, bilateral perirenal spaces, and anterior and posterior pararenal spaces were not found to be connected with each other. No fusion of ARF and PRF below the level of bilateral kidneys occurred on the left side in 28.05~ （23/82） cases and on the right side in 24.39 % （20/82）. In these patients, the PS extended to the extraperitoneal space of the pelvic cavity and fur- ther to the inguinal region, and bilateral anterior and posterior pararenal spaces were not found to be connected with each other. Three-dimensional reconstruction on contrast-enhanced MDCT could be a valuable procedure for depic- ting inferior attachment of RF, and the inferior connectivity of PS.
