Computed Tomography01:10

Computed Tomography

4.4K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

科学领域:

  • 干预神经病学 干预神经病学
  • 医疗成像医学成像
  • 血管外科 血管外科

背景情况:

  • 机械血栓切除术 (MT) 需要及时的血管接入来治疗急性中风.
  • 大动脉形几何和与年龄相关的变化可能会使访问复杂化.
  • 需要预测性成像标记器来识别访问困难.

研究的目的:

  • 评估从胸骨到上升大动脉 (S-AAD) 的距离作为成像参数,用于预测MT的血管访问困难.
  • 在MT程序中将S-AAD与引导时间 (GT) 相对应.

主要方法:

  • 对115名为前部循环大血管封闭而接受MT的患者进行了回顾性观察性研究.
  • 在手术前的胸部CT扫描上测量S-AAD.
  • 难以进入的指导时间 (GT) ≥30分钟;患者分为短GT (sGT) 和长GT (lGT).

主要成果:

  • 在sGT和lGT组之间观察到S-AAD的显著差异 (中位数S-AAD:11.9毫米与6.6毫米,P=0.026).
  • 脱脂症和S-AAD<5毫米显著与难以进入 (OR分别为5.938和5.147) 相关.
  • 10.4%的患者遇到难以进入的情况 (lGT).

结论:

  • S-AAD是一种简单,可靠的成像参数,用于预测MT的血管访问困难.
  • 这个参数可以帮助选择合适的设备和入口路线进行干预前的操作.
  • 使用S-AAD可以提高MT程序效率和成功率.
