【摘要】 依据临床观察到的门体侧枝循环形成的状况，分析了门静脉高压症对门脉循环系功能分区不同特点．胃脾区头向和尾向侧枝的变化，脾切除前后胃脾区侧枝的变化，断流术后胃脾区尾向侧枝和门脉肠系膜区尾向侧枝的改变都会使其临床表现各不相同．门体侧枝循环形成是血流动力学重要改变，观察比较这些变化有利于临床诊断和治疗．更多还原

【Abstract】 According to the clinically observated patterns of the portosystemic collaterals, this article analgses the different character of the functional compartmentation of the portal circulation. Under the situation of portal hypertension, the cephalad and caudad collaterals will be changed in the lesser splanchnic circulation. In the same way, the portasystemic collaterals in the lesser splanchnic circulation after splenectomy will differ from before. Following the pericadial devascularization the changes in the two compartments of the portal circulation will also occur. These changes and distribution of the collaterals resut in the various clinical features and are one of the important changes of the Hemodynamics. The investigation and comparision to the patterns of the portosystemic collaterals would benifit the diagnosis andtherapy for the patients with portal Hypertension.更多还原
