概括
与初级修复相比,在二次内血管大动脉干预后,植入后综合征 (PIS) 的发生率较低. 需要进一步的研究来证实这些发现,并了解免疫机制.
科学领域:
- 血管外科 血管外科
- 炎症反应综合征 炎症反应综合征
- 医疗器械技术 医疗器械技术
背景情况:
- 植入后综合征 (PIS) 是内血管动脉瘤修复 (EVAR) 后的一种全身性炎症反应,影响大约30%的患者.
- 假设PIS是一种过敏反应,可能因先前暴露而改变.
- 在EVAR之后的二次干预可能会对PIS产生不同的风险概况.
研究的目的:
- 为了确定二次内血管大动脉干预后PIS的发病率.
- 评估PIS在这个患者群体中的短期临床后果.
- 通过二次 EVAR 程序,识别与 PIS 相关的潜在风险因素.
主要方法:
- 在初级EVAR (2011-2022) 后接受二次选择性内血管大动脉干预的患者的回顾性观察性研究.
- 由温度≥38°C和C反应蛋白 (CRP) >75 mg/L定义的PIS.
- 主要结局:PIS发病率在三天内;次要结局:30天的结局和风险因素. 用于混调整的物流回归.
主要成果:
- 分析了71名患者的79项二次干预. 接受二次修复的患者年龄较大,更经常服用他类药物或抗血小板药物.
- 与初级修复 (32.3%) 相比,二次修复 (16.5%) 后PIS发病率明显较低,调整后的几率比率为0.38.
- 没有观察到发烧持续时间或炎症标志物 (CRP,白细胞计数) 峰值的显著差异,尽管在二次PIS中,CRP升高的延迟更大.
结论:
- 与初级修复相比,在二次内血管大动脉干预后,PIS的发生率似乎减少了.
- 由于程序异质性和样本规模有限,研究结果应谨慎解释.
- 需要进一步的研究来验证这些结果,并阐明PIS的潜在免疫机制.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
