Varicose Veins II: Diagnostic Studies and Interprofessional Care

325
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...

科学领域:

  • 心脏病学 心脏病学
  • 电子生理学 电子生理学
  • 医疗器械 医疗器械

背景情况:

  • 肺静脉隔离 (PVI) 的成功受到由于不完整的病变形成而导致的复发的限制.
  • 实现肺静脉周围的持久,连续的,横向的病变对于PVI疗效至关重要.

研究的目的:

  • 为了比较一种新的"双"冷热气球除技术与用于肺静脉隔离的标准除的疗效.
  • 为了确定使用多个直径的冷气球是否可以提高切除线的耐用性并减少心律失常的复发.

主要方法:

  • 226名接受冷热气球PVI的患者随机分为标准 (28mm,两个4分钟冷) 或双 (28mm和31mm,每个3分钟冷) 组.
  • 随访时间长达1年,首要结局是评估心房动脉节律失常的复发.
  • 二次结局包括并发症,心脏转变,急救诊所,住院和重复切除.

主要成果:

  • 双组在1年内显示出明显更高的复发率 (87.2%对68.9%,P=.008).
  • 在双组中,重复切除率明显较低 (1.3%对13.5%,P=.002).
  • 周围手术并发症和医疗保健利用 (心脏转移,急救访问,住院治疗) 在各组之间是相似的.

结论:

  • 双冷藏气球技术通过减少AF复发和重复手术的需要来改善PVI结果.
  • 这种方法提供了一种优越的策略,以实现对心房的冷却气球移除中持久的病变.
  • 双堆技术与帕洛西斯马和持久性AF患者的医疗保健总利用率较低有关.
