概括
深静脉动脉化 (DVA) 为慢性肢体威胁性缺血症 (CLTI) 患者提供了一种肢体救援选择,这些患者无法接受传统的再血管化. 现实世界结果显示,无截肢生存率低于之前的试验,这表明需要精确的患者选择.
科学领域:
- 血管外科 血管外科
- 干预心脏病学 干预心脏病学
- 再生医学是一种再生医学.
背景情况:
- 慢性四肢威胁性缺血症 (CLTI) 是一个重大挑战,通常会让患者有有限的重血管化选择和高的截肢风险.
- 深静脉动脉化 (DVA) 是一种复兴的技术,创建动脉静脉来通过静脉系统 perfuse 足部,针对复杂的CLTI病例.
研究的目的:
- 评估CLTI患者的深静脉动脉化 (DVA) 的实际有效性和结果.
- 将现实世界DVA结果与以前发表的试验数据进行比较,特别是PROMISE II研究.
主要方法:
- 在2021年1月至2023年12月期间,对接受DVA (CPT代码0620T) 的医疗保险收费服务受益人的回顾性分析.
- 评估的结果包括肢体救援,免受主要不良肢体事件 (主要截肢或重新干预),生存率和无截肢生存率 (AFS).
- 使用Kaplan-Meier和竞争风险分析来估计结果的累积发病率.
主要成果:
- 134名CLTI患者接受了DVA;队列是老年人,主要是男性,并患有多种并发病 (高血压,高脂血症,慢性瘤,糖尿病).
- 6个月和1年的无截肢生存率分别为42%和33%.
- 一年内肢体救援,免受主要不良肢体事件的发生率和生存率分别为53%,36%和65%.
结论:
- 深静脉动脉化 (DVA) 在高风险的CLTI患者身上进行,其预后本质上很差,肢体损失和死亡率很高.
- 在这项研究中观察到的真实世界AFS明显低于PROMISE II试验中报告的,这质疑了该程序的通用性.
- 需要进一步的研究来优化患者选择标准,并在实践中确定DVA的临床实用性.

Venous Return
2.3K
The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

Veins of Lower Limbs

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
