概括
在CT扫描上测量的肝动脉直径可以预测治疗后胃食道静脉 (GOV) 患者的出血风险. 超过4.06毫米的直径表明风险较高,有助于临床决策.
科学领域:
- 放射学 放射学是一门学科.
- 胃肠病学 胃肠病学
- 肝病学 肝病学是一种肝病学.
背景情况:
- 门性高血压是肝硬化的一种并发症,导致胃食道静脉 (GOV) 和增加出血风险.
- 肝动脉扩张与门性高血压有关,可能表明患水出血的风险较高.
研究的目的:
- 为了评估肝动脉直径的实用性,通过对比度增强CT测量,在预测GOV治疗后出血风险.
- 为了确定肝动脉直径的切割值,以确定高风险的GOV患者.
主要方法:
- 一项对258名肝硬化患者进行的回顾性研究,这些患者接受了对比度增强CT和内镜检查.
- 患者被分为测试 (治疗前) 和验证 (治疗后) 队列.
- 肝动脉直径测量在冠状CT重建;出血风险被评估内镜.
主要成果:
- 与低风险患者相比,高风险GOV患者的肝动脉直径显著更大 (4.69毫米对3.10毫米).
- 肝动脉直径的切线为4.06毫米,在测试队列中显示出高诊断性能 (AUC0.940).
- 这一切断值在测试和验证队列中显示出出色的灵敏度 (88.5-88.7%) 和特异性 (89.2-93.9%).
结论:
- 在对比度增强的CT上测量的肝动脉直径是GOV治疗后出血风险的可靠预测指标.
- 这种成像生物标志物可以帮助分层患者,并指导水出血的临床治疗.

60
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

01:24Esophageal Varices-I: Introduction
124
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
