彩色多普勒超声对肝圆韧带架桥门-腔静脉分流术后桥血管通畅性的评价

The value of ultrasonography in detection of bypass grafts after ligmentum teres hepatis-bridged combined with portacaval shunt

目的探讨彩色多普勒超声对肝圆韧带架桥门-腔静脉分流术后桥血管通畅性的观察,进而对手术疗效进行评价。方法肝圆韧带架桥门-腔静脉分流术后病人共43例,用二维超声及彩色多普勒分别于术后3、12及24个月观察桥血管通畅情况,依据桥血管不同的超声表现,分为桥血管通畅组和桥血管狭窄组两组。结果术后3个月,有41例血管通畅,2例血管狭窄;术后12个月38例血管通畅,5例血管狭窄;术后24个月30例血管通畅,13例血管狭窄,随着时间的延长桥血管发生狭窄的概率增加,术后3个月与24个月比较,P<0.05。结论术后彩色多普勒超声监测桥血管是评价手术效果的重要手段。

Objective To explore the value of ultrasonography in detection of bypass grafts after Ligmentum teres hepatis-bridged combined with portacaval Shunt.Methods There were 43 patients of bypass grafts after Ligmentum teres hepatis-bridged combined with portacaval Shunt.Two-dimensional ultrasound and color Doppler was used to observed the bypass grafts at 3,12 and 24 months respectively after the operation.According to different ultrasonic manifestations of bypass grafts,2 groups were divided:group of patency of bridging vessels and group of Bridge stenosis.Results Three months after surgery,there were 41 cases with vascular patency,and 2 cases with vascular stenosis;twelve months after surgery,there were 38 cases with vascular patency,and 5 cases with vascular stenosis;Twenty-four months after surgery,there were 30 cases with vascular patency,and 13 cases with vascular stenosis.The probability of stenosis of the bypass grafts increased with time,while 3 months after surgery was compared with 24 months after surgery,P<0.05.Conclusion The color Doppler ultrasound was used as an important method to evaluate the success of the operation.
