概括
与光镜相比,超声波导向 (USG) 穿刺用于跨导管大动脉植入 (TAVI) 访问显著减少了血管并发症和出血. 采用USG作为标准护理可以提高TAVI程序中的患者结果.
科学领域:
- 心血管干预 心血管干预
- 在程序中的医学成像.
- 血管接入技术 血管接入技术
背景情况:
- 过导管大动脉植入 (TAVI) 携带血管和出血并发症的风险.
- 超声指导 (USG) 穿孔可以减轻这些风险,特别是在大孔通道上.
- 由于缺乏足够的大规模数据,USG对TAVI访问的广泛临床采用是有限的.
研究的目的:
- 为了比较TAVI中USG和光学引导访问之间的与访问相关的血管和出血并发症.
- 评估USG访问在大型多中心TAVI注册表中的安全性和有效性.
主要方法:
- 从PULSE注册表 (2016-2021) 中,对9295名接受体输血TAVI的患者进行了回顾性分析.
- 在USG (n=1992) 和光学引导 (n=7303) 访问组之间进行比较.
- 倾向性得分匹配 (1:1) 创建了895对匹配对,用于分析主要终点 (血管并发症或II-IV型出血).
主要成果:
- 在USG组中,复合主终点发生的频率较少 (11.7%) 与光镜 (16.0%;OR 0.7,P=0.01) 相比.
- USG访问与手术出血率显著降低 (5.4%与9.2%相比;OR0.56,P=0.002).
- 在USG组观察到更低的内血管治疗率 (0.7%对2.5%;P=0.005).
结论:
- 与光镜相比,超声导入输血TAVI与血管并发症和出血的减少有关.
- 实施USG穿刺作为标准实践可能会改善TAVI患者的安全性和结果.
- 进一步的研究和将其纳入临床指南是有必要的,以促进USG的采用.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
