脾脏机能的现代认识过去认为脾切除不影响生命,因此,脾脏对生命的维持不是必不可少的。但是现在已经越来越明确的认识到,它的生理机能的独特性,对于人体也是非常重要的,现将其分成如下几方面加以叙述。 1.脾的解剖特点及血液循环动态脾脏质软而脆呈暗红色,脾动脉来自腹腔动脉干,沿胰腺上缘走向脾门并分出胃短动脉和胃网膜左动脉。脾静脉由脾门静脉诸支汇合而成,经胰后上缘向右走行,在脾动脉的深面下方。与胰腺颈部和肠系膜上、下静脉汇流成门静脉。脾的血管在脾门处分成敛被,出入脾门同时并行,这对于脾脏外科、行部分牌切除是其有利条件。脾的淋巴引流汇集于脾门淋巴结,然后沿脾血管右行,进入腹脏动脉旁淋巴结。
The modern understanding of the spleen function in the past that splenectomy does not affect life, therefore, the spleen to maintain life is not essential. However, it is now becoming more and more clear that its unique physiological function is also of great importance to the human body, and is now divided into the following aspects to be described. 1. Anatomical characteristics of the spleen and blood circulation Dynamic spleen soft and crisp dark red, splenic artery from the celiac trunk, along the upper edge of the pancreas toward the spleen door and the separation of the gastric artery and the left gastric artery. Splenic vein by the splenomegaly merger made by the upper edge of the pancreas to the right after the line, deep in the lower surface of the splenic artery. And pancreatic neck and superior mesenteric, inferior venous confluence into portal vein. Splenic blood vessels in the spleen at the door into Convergence, access splenic door parallel at the same time, which for the spleen surgery, the line part of the card resection is its favorable conditions. Spleen lymphatic drainage pool in the spleen lymph nodes, and then along the right spleen blood vessels, into the abdominal aortic lymph nodes.
