背景情况:
- 调查常见阴静脉 (CIV) 压缩和下腔静脉 (IVC) 血栓形成对IVC过器使用和血栓管理具有临床意义.
- 了解CIV压缩度对下肢深静脉血栓 (DVT) 患者IVC血栓发生率的影响至关重要.
研究的目的:
- 澄清常见阴静脉 (CIV) 压缩度对下腔静脉 (IVC) 血栓发生率在患有下肢深静脉血栓 (DVT) 患者中的影响.
主要方法:
- 391名患者的单中心回顾性研究 (2015年1月至2023年7月).
- 使用计算机断层扫描静脉学对CIV最小直径和压缩百分比的定量评估.
- 分析包括单变量,多变量,倾向性得分匹配 (PSM) 和受限立方线 (RCS).
主要成果:
- 阴腿腹腔DVT和较大的CIV最小直径增加了IVC血栓形成风险;年龄较大和压缩率较高降低了风险.

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...

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
