在30具成人尸体制成的腹部连续横断面标本上(其中8具为肾周间隙灌注后制成的,6具为肾周间隙灌注并作CT扫描后制成的断面标本,断面厚约1.00cm),观察了腹膜后间隙向内侧通连的情况,结果如下:1.肾旁后间隙向内侧的延伸随肾后筋膜内侧端附着位置的变化而变化,肾后筋膜内侧端附着点变化在腰方肌稍外侧的腹横筋膜和腰大肌后外侧部的筋膜之间,但集中附着在腰方肌外侧3/4的筋膜上,在肾门和肾下极平面分别占80%和90%左右.2.两侧肾周间隙完全不通者占30%左右,而通连者约70%,前者的肾前筋膜向内侧与腹部大血管及其周围结缔组织紧密连接,后者的肾前筋膜向内侧经肾血管和腹部大血管的前方与对侧同名筋膜延续,与血管间为疏松结缔组织所填充.在70%的连通中,肾门平面连通的为100%,L_3～5单面的占16%,另有8%可在Th_(11～12)平面,主动脉裂孔的前上方经膈前方通连,而腹腔动脉和肠系膜上动脉起始部之间的区域由于有大量致密结缔组织、神经丛和节的存在以及肾前筋膜与此的紧密连接,为不能通连区.3.肾旁前间隙在胰平面因胰在腹后壁的横垮可两侧通连,但间隙灌注显示灌注剂多局限在灌注侧.在联平面以下,两侧间隙由于肠系膜根在腹后壁的附着而被阻隔.熟悉腹膜后间隙的内侧延伸和通连情况,对腹膜后间隙疾患尤其积液的诊治具有?
Thirty adult cadaver abdominal continuous cross-sectional specimens (of which 8 were perinephric perfusion, 6 peritoneal perfusion and CT scan made of cross-section specimens, section thickness of about 1.00 cm), observed the situation of the retroperitoneal space to the medial connection, the results are as follows: 1. The extension of the renal side of the gap to the medial extension of the posterior kidney fascia medial end of the attachment position changes, the posterior kidney fascia medial end attachment points Changes in the lateral lateral muscle of the lateral transverse fascia and the psoas major lateral fascia, but the focus attached to the outer side of the 4/4 of the fascia, in the renal hilus and the lower pole of the plane were accounted for 80% and 90% .2. Both sides of the perirenal space completely unreasonable about 30%, while about 70%, the former of the anterior fascia to the medial and abdominal large vessels and connective tissue closely connected, The latter prerenal fascia to the medial by the renal blood vessels and abdominal large blood vessels in front of the same name and the contralateral fascia continued with the blood vessels loose connective tissue filled in 70% of the connectivity, the plane of the renal portal connectivity of 100 %, L_3 ~ 5 single-sided accounted for 16%, and another 8% in the Th_ (11 ~ 12) plane, aortic atherosclerosis in front of the top of the diaphragm through the front, and The area between the celiac artery and the beginning of the superior mesenteric artery is a zone of inaccessibility due to the presence of a large number of dense connective tissue, the presence of plexuses and nodes, and the prerenal fascia .3. Pancreatic flat due to the pancreas in the ventral posterior wall of the collapse can be connected on both sides, but the perfusion showed perfusion more perfusion side .In the joint plane, both sides of the gap due to the attachment of the mesenteric root in the ventral wall was blocked. Familiar with the retroperitoneal space and medial extension of the situation, especially for the diagnosis and treatment of retroperitoneal space disease with fluid?
