概括
气球辅助次极入口 (BASE) 技术用于复杂的慢性全闭塞 (CTO) 穿皮冠状动脉干预 (PCI). 这种方法显示了中等的成功率,主要心脏不良事件 (MACE) 的发病率很低.
科学领域:
- 干预心脏病学 干预心脏病学
- 心血管干预 心血管干预
- 通过皮肤进行冠状动脉干预.
背景情况:
- 关于在慢性全闭症 (CTO) 穿皮冠状动脉干预 (PCI) 中应用气球辅助次极入口 (BASE) 技术的数据有限.
- 了解BASE技术的利用和结果对于复杂的CTO PCI策略至关重要.
研究的目的:
- 使用BASE技术分析CTO PCI病例的临床和血管学特征.
- 在CTO PCI中评估与BASE技术相关的结果.
- 为了比较BASE技术的使用与其他前级解剖和重新进入 (ADR) 策略.
主要方法:

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
