曲张静脉表面呈樱桃红色或积血色斑(红色征)是门脉高压患者食管曲张静脉出血的危险因素。有认为这种内窥镜下的征象可反映组织学上的上皮内血管充血扩张。本文测定肝硬化食管曲张静脉的跨壁压(TOVP),并研究 TOVP 与各种临床、实验室和内镜参数的关系。方法 40例有中度或重度(直径>2mm)食管曲张的肝硬化患者,于第一次硬化疗法前,在内镜下直接测定 TOVP。全部病例均未服过出血预防药,亦未用过曲张静脉或门脉的降压药。全部腹水患者及12/29例无腹水患者正在接受利尿药治疗。测压前记录有无
Varicose vein surface cherry red or hemorrhagic bloody stain (red sign) is a risk factor for portal hypertension in patients with esophageal variceal bleeding. It is thought that this endoscopic sign may reflect the histological intraepithelial vascular congestion expansion. This article measures the transvaginal pressure (TOVP) of cirrhotic esophageal varices and investigates the relationship between TOVP and various clinical, laboratory and endoscopic parameters. Methods Forty patients with cirrhosis who had moderate or severe esophageal varices (diameter> 2 mm) were treated with TOVP directly under endoscopy before the first sclerotherapy. All cases were not given prophylactic prophylaxis, nor have used varicose veins or portal antihypertensive drugs. All patients with ascites and 12/29 patients without ascites are receiving diuretics.
