概括

持续的左上静脉 (PLSVC) 与下心房 (AF) 在切除后的复发有关. 重复除显著改善了PLSVC患者的AF自由,这表明其潜在的益处.

科学领域:

心脏病学心脏病学
电子生理学电子生理学
医疗成像医学成像

背景情况:

持续的左上 vena cava (PLSVC) 是一个解剖学变异,可以与心房动 (AF) 相关.
了解PLSVC对AF切除结果的影响对于患者管理至关重要.

研究的目的:

为了比较PLSVC患者与没有PLSVC (n-PLSVC) 的匹配队列中经过切除后1年无复发性心房动心 (AT) 或AF的情况.

主要方法:

追溯病例对照研究 (2008-2022) 涉及15名PLSVC患者和75名匹配对照.
倾向性得分匹配用于控制包括年龄,性别,BMI,AF类型,切除能量和左心房体积在内的变量.
排除标准包括不到1年的随访或之前的手术切除.

主要成果:

与n-PLSVC对照组 (59%,p=0.02) 相比,PLSVC患者 (27%) 的1年无AF自由度显著较低.
在PLSVC患者中,33%接受了PLSVC的直接切除,所有患者在一年内都出现了复发的AT/AF.
在PLSVC患者中重复AF切除后,在2.1年的中位随访期内实现了83%的AF脱离.

结论:

与没有PLSVC的患者相比,PLSVC的患者在去除后的AF初始自由度较低.
重复的切除手术可以显著改善PLSVC患者长期无AF的状况.
需要进一步的研究来优化PLSVC的废弃策略,包括脉冲场废弃的潜在作用.

Varicose Veins II: Diagnostic Studies and Interprofessional Care

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...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
