在门脉高压中,胃左静脉(LGV)是通往食管曲张静脉的一主要通路。作者用多普勒检查其血流,并阐明其在肝硬变中的变化。 对53例健康对照(男19例,女34例,平均年龄48±16岁)和216例肝硬变病人(男153例,女63例,平均年龄57±9岁)。用带3.75MHz电子扇形探头的双功脉冲多普勒流量表(东芝SSA100A,270A),作多普勒检查。脉冲频率为4.0kHz、取样容积按LGV的直径从2、3、5和10cm宽度中选择。血流方向和速度由多普勒频移的快速傅里叶变换获得。B超扫描以确定LGV。研究对象禁食一夜,仰卧
In portal hypertension, the left gastric vein (LGV) is a major pathway to the esophageal varices. The authors examined their blood flow with Doppler and clarified their changes in cirrhosis. A total of 53 healthy controls (19 males and 34 females with an average age of 48 ± 16 years) and 216 patients with liver cirrhosis (153 males and 63 females with a mean age of 57 ± 9 years) were included. Doppler examination was performed using a bipolar pulsed Doppler flowmeter (Toshiba SSA100A, 270A) with a 3.75 MHz electronic sector probe. The pulse frequency is 4.0 kHz and the sampling volume is selected from the 2, 3, 5, and 10 cm widths by LGV diameter. The direction and velocity of blood flow are obtained from the Fast Fourier Transform of the Doppler shift. B-scan to determine LGV. Study fasting overnight, supine
