概括
慢性四肢威胁性缺血症 (CLTI) 干预后,脆弱性通常会增加,其中27%的人在一年内变得脆弱. 这种转向脆弱状态与更糟糕的生存结果有关,强调需要仔细评估患者.
科学领域:
- 血管外科 血管外科
- 老年医学 老年医学
- 患者研究成果研究结果
背景情况:
- 在手术患者中,脆弱性很普遍,预示着不良结果.
- 慢性四肢威胁性缺血症 (CLTI) 影响了大量需要干预的患者群体.
- 了解脆弱过渡对于管理CLTI患者至关重要.
研究的目的:
- 分析为CLTI进行下肢再血管化或截肢的患者的虚弱状态的变化.
- 为了确定与脆弱过渡相关的因素.
- 评估脆弱性转移对临床结果的影响.
主要方法:
- 对1859名CLTI患者 (2018-2022) 的回顾性分析,这些患者接受了内血管干预 (EV),旁路 (BYP),大截肢 (AMP) 或伤口护理.
- 使用血管质量倡议衍生风险分析指数 (≥35定义为脆弱) 评估的脆弱性.
- 使用多变量考克斯回归分析的虚弱过渡 (手术前到1个月和1年);评估了没有截肢的生存率和没有主要不良肢体事件的情况.
主要成果:
- 25%的患者最初是脆弱的;整体脆弱性在30天后增加到34%,并在1年后增加到40%.
- 一年后,27%的患者从非脆弱转变为脆弱,9%的患者从脆弱转变为非脆弱,治疗方式各不相同.
- 术后转移到脆弱状态与较高的并发症指数,降低的生存率和较低的无截肢生存率相关.
结论:
- 显著比例的CLTI患者经历了干预后过渡到脆弱状态,特别是在内血管干预和伤口护理后.
- 干预后的脆弱性转变与较差的生存率和不利的肢体结果有关.
- 在临床评估和CLTI患者的管理策略中,应考虑脆弱性状态的变化.

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...
