概括
对于慢性肢体威胁性缺血症,自主静脉绕道手术提供了优越的无截肢生存率和整体生存率与内血管治疗相比. 然而,当自身静脉不可用时,内血管治疗可能是首选的.
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:
- 涉及关动脉的慢性四肢威胁性缺血症 (CLTI) 提出了重大的临床挑战.
- 像BASIL-2和BEST-CLI这样的现有研究在内血管治疗 (EVT) 与外科绕道 (BP) 之间提供了相互矛盾的证据.
- 需要对现实世界注册表进行比较,以澄清下流层CLTI的治疗疗效.
研究的目的:
- 为了比较EVT与手术绕道 (BP) 的现实世界结果,在需要下人群干预的CLTI患者中.
- 评估无截肢生存率 (AFS),整体生存率 (OS) 和没有重大截肢的情况.
- 为了评估BP的结果,使用自身静脉 (BPAV) 和假体导管 (BPPC) 与EVT对比.
主要方法:
- 对血管质量倡议 (VQI) 外围血管干预和下内绕道注册表 (2017-2022) 的分析.
- 包括为CLTI进行的人口内手术的患者.
- 构建倾向分数匹配的队列,以比较EVT与BP,EVT与BPAV以及EVT与BPPC.
主要成果:
- BP和EVT显示了相当于2年的AFS (50.3%对49.0%),但BP具有优越的OS (79.7%对75.6%) 和下肢救援 (71.4%对81.4%).
- 与EVT相比,BPAV (主要是大沙静脉) 显示出优越的2年AFS (53.9%与52.5%) 和OS (81.1%与77.4%) 与相当的四肢救援相比.
- 与EVT相比,BPPC的2年AFS (44.1%与46.9%) 和四肢挽救率 (63.3%与77.5%) 显著低于EVT,尽管OS.
结论:
- 由于更好的AFS和OS,当可行时,应优先选择自主静脉绕道 (特别是大沙静脉),而不是CLTI的EVT,因为更好的AFS和OS.
- 当自身静脉不可用时,内血管治疗可能是首选的选择,提供比假肢旁路更好的AFS和四肢救援.
- 这些发现提供了关键的现实世界数据,用于在复杂的低人口CLTI中做出治疗决策.

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Sites for measruring blood pressure
2.4K
Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
