概括
介质动脉狭窄,特别是在上介质动脉 (SMA) 和下介质动脉 (IMA) 中,在结直肠手术后显著增加了解静脉泄漏的风险. 手术前的CT扫描可以识别这种风险,指导潜在的干预措施.
科学领域:
- 这是血管外科手术.
- 胃肠道手术 胃肠道手术
- 放射学 放射学是指放射学
背景情况:
- 静脉漏 (AL) 是结直肠外科手术的严重并发症.
- 从中枢动脉 (MA) 狭窄症中受损的血液流动可能会损害解静脉的愈合.
- 在手术前确定MA狭窄症可以预测AL风险.
研究的目的:
- 为了研究手术前介质动脉狭窄症和结直肠手术后的静脉泄漏 (AL) 之间的关联.
- 为了确定特定中腔动脉 (SMA,IMA) 的狭窄是否与AL相关.
- 评估计算机断层扫描 (CT) 扫描在识别与AL相关的MA狭窄时的诊断价值.
主要方法:
- 一项多中心,回顾性,病例控制研究,涉及130名AL患者和627名匹配的对照.
- 在手术前的CT扫描中,分析了中腔动脉狭窄的存在 (≥50%).
- 病例和对照对年龄和体重指数进行了匹配;分析对已知的AL风险因素进行了调整.
主要成果:
- 在AL患者 (13.8%) 和对照组 (2.2%) 中,SMA狭窄的患病率 (≥50%) 显着更高.
- 在AL患者 (24.6%) 和对照组 (12.1%) 中,IMA狭窄的患病率 (≥50%) 也较高.
- SMA 狭窄增加了5.9倍的AL风险,IMA狭窄增加了2.1倍的AL风险,独立于其他风险因素.
结论:
- 在CT扫描上检测到的手术前的SMA或IMA狭窄 (≥50%) 是结直肠手术后AL的重要危险因素.
- 这些发现表明,在手术前确定中腔动脉狭窄症对于风险分层至关重要.
- 需要进一步的研究来评估预防性干预措施的有效性,例如在中枢动脉狭窄时放置支架,以减少AL.

Esophageal Varices-I: Introduction
74
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...

Esophageal Strictures-I: Introduction
65
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
