断流术加胃减动脉术的意义和胃减动脉术式的探讨

设计了丝线胃网膜右动脉枉性栓塞术，用在门脉高压症（PH）断流术中，以进一步减少胃壁动脉的血供、缓解术后胃里局部的静脉高压状态、防止术后门脉高压性胃病（PHG）的发生发展及增加断流的彻底性。以16条PH模型犬为对象，与现存的其它两种术式—胃网膜右动脉主干结扎和胃网膜右动脉主干及其胃支离断（统称为“胃减动脉术”）进行对照研究。结果表明，该方法即可以克服胃网膜右动脉主干结扎的效果不持久，又能避免胃网膜右动脉主干及其胃支离断的胃壁缺血坏死等弊端。有希望成为在PH断流术中进一步减少胃壁动脉血供的理想术式。

THE SIGNIFICANCE OF PAD WITH GAR AND THE STUDY OF GAR MODE

The author designed the right gas-troepiploic artery(RGEA) chronic embolization with silk for the portazygons disconnection procedure (PAD) of portal hypertension (PH) to decrease the blood support of gastric wall, and reduce the hyper-tensive state of gastric intramural venous, so as to avoid the occurrence or development of portal hy-pertensive gastropathy (PHG ) after PAD, and in-creace thoroughness of PAD. A contrasting study was carrided out on 16 model dogs of PH between the new operation mode and two of the remaining modes-the ligature of the main stem of RGEA and the cutting of the main stem and gastric branch of RGEA called by a joint name as "Gastric Artery Rheopexy Procedure (GAR)"]. The results indicat-ed that the method not only can overcome the short-coming that the effect of RGEA ligature cannot maintain long time, but also can avoid the ischemia and necrosis of gastric wall after the stem and gas-tric branch of RGEA were amputated. lt deserves high hopes to become an ideal mode to reduce the
