肾筋膜减压平面在腹膜后病变CT诊断中的应用

Decompression Plane of Renal Fasciae: Its Value in CT Diagnosis of Retroperitoneal Lesions

目的 进一步探讨肾筋膜减压平面的解剖及其在腹膜后病变CT诊断中的应用。资料与方法 搜集 37例腹膜后病变病例 ,其中急性胰腺炎 2 3例 ,肾及肾周病变 14例。均采用CT扫描。结果 所有病例在CT上均可见不同程度和范围的肾筋膜和桥隔增厚。结论 将肾筋膜减压平面分为肾前筋膜前平面、肾前筋膜后平面、桥隔旁平面、肾后筋膜前平面及肾后筋膜后平面有助于加深对腹膜后病变CT表现的理解和提高CT诊断的准确性。

Objective To make a further understanding of the anatomy of decompression plane of the renal fasciae, to discuss its use in CT diagnosis of retroperitoneal lesions. Materials and Methods Thirty-seven patients with retroperitoneal lesions were enrolled in this study. All patients underwent CT scanning. Of the total 37 cases, 23 were acute pancreatitis, 14 were renal or perirenal lesions.Results Thickening of renal fasciae of different degree and extent was found on CT scans in all cases. Conclusion Renal decompression plane can be divided into anterior and posterior planes of the anterior renal fasciae, para-bridging-septa plane, and anterior and posterior planes of the posterior renal fasciae. This classification is helpful for the understanding of CT signs of retroperitoneal diseases and for the improvement of the diagnostic accuracy.
