【摘要】：目的 探讨内镜下食管静脉曲张套扎术(EVL)后门静脉血流动力学的变化,为临床防治肝硬化并食管静脉曲张破裂出血(EVB)提供指导。方法 选取64例肝硬化并食管静脉重度曲张破裂出血的患者作为研究对象,行内镜下食管静脉曲张套扎术,套扎前后用彩色多普勒超声对门静脉及其属支的血管管径、血流速度、血流量进行分析与比较。并对研究对象进行随访1年,考察行术后患者再出血及死亡病例的情况。结果 EVL近期止血成功率为96.9%,1年内再出血率为9.7%,术后患者门静脉和脾静脉的血流速度与血流量明显增加(P0.05),胃左静脉血流由离肝血流转变为向肝血流。结论 EVL是治疗和预防EVB安全有效的方法;EVL后门静脉和脾静脉的血流速度、血流量增加,肝脏的血液供应增大。
[Abstract]:Objective to investigate the changes of portal vein hemodynamics after endoscopic esophageal variceal ligation (EVLL), and to provide guidance for clinical prevention and treatment of cirrhosis with esophageal variceal hemorrhage. Methods Sixty-four patients with cirrhosis and severe esophageal variceal bleeding were selected as study subjects. Endoscopic esophageal variceal ligation was performed. The diameter of portal vein and its branches was measured by color Doppler ultrasound before and after ligation. Blood flow velocity and blood flow were analyzed and compared. The patients were followed up for 1 year to investigate the postoperative bleeding and death. Results the recent success rate of hemostasis in EVL was 96.9 and the rate of rebleeding within one year was 9.7. The blood flow velocity and blood flow of portal vein and splenic vein increased significantly (P 0.05), and the blood flow of left gastric vein changed from free liver flow to liver flow. Conclusion EVL is a safe and effective method for the treatment and prevention of EVB.
