- 胸部外科手术 胸部外科手术
- 大动脉疾病 大动脉疾病
背景情况:
- 不复杂的斯坦福B型大动脉剖析 (TBAD) 可以导致晚期的大动脉并发症.
- 鉴定患有这些并发症高风险的患者仍然是一个临床挑战.
研究的目的:
- 确定一个最佳的成像参数,可以预测与大动脉相关并发症的风险,在没有并发症的TBAD患者.
主要方法:
- 对213名没有并发症的TBAD患者的前性收集数据的回顾性分析.
- 序列计算机断层扫描 (CT) 图像分析,以评估随访期间成像参数和大动脉相关并发症之间的关联.
主要成果:
- 在最初的亚急性阶段,较低的真面积比率 (TLAR) (<2.9%) 是晚期主动脉相关并发症的显著预后因素.
- 低TLAR (HR,6.32) 和扩大的虚假光线面积 (HR,6.09) 是并发症的独立预测因素.
- ≤52.9%的TLAR增加了并发症风险,即使大动脉直径小于40毫米.

Aortic Regurgitation I: Introduction
3
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

The Aorta
660
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...
