目的:研究胃左静脉(LGV)的超声解剖及其血流动力学特征。方法:测定正常组胃左静脉内径,观察其走向及汇合点,确定血流方向和流速,并以门脉高压者作为对照组,观察胃左静脉与门脉的汇合点。结果:71.5％的胃左静脉得到确认,96.5％的胃左静脉汇合于脾静脉或脾门静脉交界处。结论:大多数人的胃左静脉可以用彩色多普勒超声检测到,并可以作为早期诊断门脉高压的重要指标。
Objective: To study the ultrasonic anatomy and hemodynamics of gastric left venous (LGV). Methods: The diameter of gastric left venous vein in normal group was measured, the direction and confluence of gastric left ventricular in normal group were observed, the direction and velocity of blood flow were determined, and the portal hypertension was used as the control group to observe the confluence of gastric left venous and portal. Results: 71.5% of the left gastric vein was confirmed, 96.5% of the left gastric vein confluence in the splenic vein or splenic vein junction. CONCLUSIONS: The gastric left venules of most people can be detected by color Doppler ultrasound and can be used as an important indicator for the early diagnosis of portal hypertension.
