肝动脉鞘切除术对门静脉高压症肝动脉血流量影响的研究

因肝硬化门静脉高压择期行脾切除门奇断流术２０例按入院先后分为两组（各１０例）。加肝总动脉鞘切除作处理组。术前、术后２周、术后３个月用超声多普勒直固有动脉、门静脉血流量。处理组术后２周肝固有动脉血流量交术前增３０％，术后３个月仍维持较术前增加１８％的量，最高可达４０％。病人住院时间较对照组平均少５天。门 干血流量未受肝固有动脉血流量增加的影响。门奇断流术不减少病人肝门静脉血流量，手术中加作肝总动脉鞘

The effect of neunectomy of common hepatic artery in patients with protal hypertension on the hepatic artery blood flow.

The improvement of blood supply of hepatic cells is an important factor to maintain impaired hepatic function.Neunectomy has been proved to be an effective procedure in a series of 20 patients,who had suffered from portal hypertension following hepatitis B and underwent portal azygous disconnection combined with splennectomy.Neunectomy has been added in 10 patients alternatively according to the admisson date(management group:N the rest 10 patients as control C group.The alternation of blood flow of proper hepatic artery and main trunk of portal vein has been monitored 2 weeks,3 months postoperatively.The proper hepatic artery blood flow increased by 30%(P<0 05 and 18% respectively than before operation in the management group,while the blood flow of proper hepatic artery in the control group in only 3% more and even lower respectively than before.The increase of portal vein blood flow after operation did not shouw significant both in the N and C group.The clinical results in N group is satisfied the hospitaliztion is 5 days less in N group than in C group in average.The neunectomy of common hepatic artery in cirrhotic patient is justified.
