摘　　要：采用Wistar大鼠行保留胃冠状静脉的远端脾腔分流术(DSCS),远端脾肾分流术(DSRS)及结扎胃冠状静脉的DSCS,动态观察术后自由门脉压(FPP),自由脾静脉压(FSP)及门脉、脾静脉染色显影情况;结果表明保留冠状静脉分流的DSCS,区域性减压效果明显优于结扎冠状静脉的DSCS,术后早期可维持门脉压力,术后40天FPP开始呈下降趋势,同时染色显影发现脾胰间出现细条状侧支,术后60天出现索片状模糊侧支,表明DSCS(DSRS)随时间的延长出现脾胰离断后的新生侧支。Distal splenoeaval shunt with retained left gastric vein (DSCS) and distal splenbrenal shunt (DSRS) associated with ligation of left gastric vein were performed on Wistar rats. Postoperative free portal pressure (FPP), free splenic vein pressure (FSP), angiographic change of portal vein and splenic vein also have been observed dynamically. The results showed that regional decompression by DSCS with retained left gastric vein was remarkably superior to that of DSCS with ligation of left gastric vein, with preservation of portal pressure at early postoperative period. FPP began to decrease in DSCS group with the development of some fine collaterals between spleen and pancreas 40 days after operation. Cordlike collaterals and vague patches of collaterals could be visualized angiographically at 60th postoperative day. It was showed that DSCS (DSRS) tend to lose its effect of selective decompression over time due to the occurrence of new collaterals between spleen and pancreas.
