超声引导对经皮肝胃冠状静脉栓塞术的辅助作用

目的探讨超声引导对经皮肝胃冠状静脉栓塞术（PTVE）治疗肝硬化上消化道出血的辅助作用。方法52例经超声引导下PrrVE作为观察组，37例采用盲穿门静脉行PTVE作为对照组。比较2组患者穿刺成功率、穿刺时间（指确定穿刺点至导管置入时间）、栓塞效果及并发症发生率。结果观察组1次穿刺成功率（73．1％）显著高于对照组（43．2％），P〈0．05具有统计学意义。观察组1次穿刺成功时间（2．3±0．6）min显著低于对照组（4．2±0．8）min，P〈0．05具有统计学意义。观察组栓塞成功率（100％）显著高于对照组（86．5％），P〈0．05具有统计学意义。观察组并发症发生率低于对照组。结论超声引导对PTVE具有重要的辅助作用，能准确判断门静脉位置，增加了穿刺成功率，提高了穿刺速度。

Auxiliary effect of ultrasonic guidance for percutaneous transhepatic varices embolization

Objective To explore the auxiliary effect of ultrasonic guidance for percutaneous transhepatic varices embolization （FPVE） for the treatment of hemorrhage of upper gastrointestinal with cirrhosis. Methods Fifty-two patients arranged PTVE by ultrasonic guidance were considered as observation group, and 37 patients arranged PTVE by blind paracentesis were considered as control group. The paracentesis success ratio, time of paracentesis, results and rate of complications in the two groups were compared. Results The achievement ratio of one- time puncture in observation group（73.1% ） was significantly increased than that in control group（43.25 ）. The differences were statistically significant（ P 〈 0.05 ）. The time of paracentesis in observation group （ 2.3 ± 0.6 ） rain was shorter than that in control group （ 4.2 ± 0.8 ） min. The differences were statistically significant（ P 〈 0.05 ）. The rate of embolization rate in observation group（ 100% ） was obviously higher than that in control group （ 86.5 % ）, the differences were statistically significant （ P 〈 0.05 ）, and the rate of complications was less than that in control group. Conclusion The ultrasonic guidance plays an important assistant roles for PTVE,it is helpful to determine the location of portal vein and increase the paracentesis succeed ratio and speed. It is safe and deserved to be spread.
