目的 为膈下间隙病变的断层影像学诊断和外科治疗提供实用的形态学依据。 方法 在 30例成人尸体上腹部连续冠状断层标本和 2例尸体腹部磁共振冠状图像上 ,研究了膈下间隙的冠状断层解剖。 结果在冠状断层上 ,膈下间隙分为肝周间隙和脾周间隙 ;胃胰襞左部前缘和小网膜左部 (肝胃韧带 )后层之间的间隙构成网膜囊上、下隐窝间的唯一直接交通 ,其交通形式在冠状面上可分为 3型。胃膈韧带右层与小网膜的后层相续 ,左层与膈脾韧带右层及胃脾韧带后层相续 ,向下左、右层靠拢而续为胃胰襞左部。胃裸区居胃膈韧带的左、右层之间 ,其存在率为 10 0 %。脾裸区居膈脾韧带、胃脾韧带、脾肾韧带和脾结肠韧带之间 ,在脾肾韧带处最宽 ,脾裸区可分为脾门部和脾肾部 ,其最大值分别为 :2 6 4± 1 16cm ,4 16± 2 2 4cm。 结论 冠状断层是显示胃胰襞左部及网膜囊上、下隐窝间通连关系的优势断层。网膜囊上、下隐窝相通的约占观察总例数的 73 3%
Objective To provide a practical morphological basis for the diagnosis and surgical treatment of subgapsional space lesions. Methods Coronal dissection of the subphrenic space was studied on 30 cases of adult cadaver abdominal continuous coronal section and 2 cases of coronal abdominal magnetic resonance coronary angiography. Results In the coronal section, the subphrenic space was divided into the perihepatic space and the splenic space; the gap between the left front edge of the stomach pancreas and the posterior layer of the lesser omentum The only direct traffic between crypts, the traffic form in the coronal plane can be divided into 3 types. The right layer of the diaphragm diaphragm and the small retinal after the phase continued, the left and the right of the splenic and splenic ligament and splenic ligament posterior continuous phase, the lower left and right layers closer and continued to the left part of the stomach and pancreas. The gastric nude region occupies the left and right layers of the diaphragm diaphragm ligament, its presence rate was 10%. Splenic nude area home phrenic splenic ligament, stomach spleen ligament, spleen and kidney ligament and splenic ligament between the spleen and kidney ligament at the widest point, splenic uncrowded area can be divided into splenomegaly and spleen and kidney, the maximum values were: 2 6 4 ± 1 16cm, 4 16 ± 2 2 4cm. Conclusions Coronal is the predominant lesion that shows the relationship between the left part of the stomach pancreas and the superior and inferior crypts of the omentum. Retina sac, under the crypt associated about the total number of cases observed 73 3%
