- 干预性放射学 干预性放射学
- 血管成像 血管成像
- 骨关节炎的治疗方法
背景情况:
- 生殖关节动脉栓塞 (GAE) 是一种治疗膝关节骨关节炎的方法.
- 目前还没有针对GAE的标准化,定量终点.
- 血管学终点"修剪"已经被主观地定义.
研究的目的:
- 在GAE中确定血栓终点的定量替代参数.
- 建立客观的标准来评估GAE程序中的栓塞成功.
- 为了将成像发现与接受GAE的患者的临床结果相关联.
主要方法:
- 数字减去血管学 (DSA) 图像被合并并转换为彩色图.
- 细分软件被用来测量血栓化前后的红斑大小,计算红斑减少比率 (BRR).
- 评估了骨关节炎严重程度和临床结果 (KOOS),并记录了栓塞血管和体积数据.
主要成果:
- 脸红的大小和栓塞体积随着骨关节炎程度的提高而增加.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
