心血管干预心血管干预
血管外科血管外科
干预性放射学干预性放射学

背景情况:

传统的关节动脉进入关节下支架带来了诸如出血和延长恢复等风险.
跨射线动脉接入 (TRA) 减少了血管并发症,但有辐射动脉封闭 (RAO) 的风险.
远距离透射接入 (dTRA) 作为具有较低阻塞率的替代方案出现.

研究的目的:

评估使用双边远端透射接入 (dTRA) 用于皮肤间治疗关节下动脉狭窄的安全性和技术可行性.

主要方法:

诊断血管造影使用SIM2导管通过逆侧通道在10名患有关节下动脉狭窄的患者中进行.
然后进入ipsilateral远端辐射动脉,用于输送气球可扩展支架.
这项研究涉及10名被诊断患有不同程度的关节下动脉狭窄症的患者.

主要成果:

在双边远端辐射动脉穿刺和关节下狭窄干预方面,获得了100%的成功率.
在1个月的随访期间,没有观察到放射性动脉封闭 (RAO) 或关节下动脉复缩的情况.
在所有10个案例中,程序都成功完成,涉及9名男性和1名女性,平均年龄为65.8岁.

结论:

双边dTRA是一种安全的,最小侵入性的,并且在人体工程学上有利的方法,用于治疗下关节狭窄症患者.
这种方法为传统方法提供了可行的替代方案,提高了患者的舒适性和操作人员的方便性.

Peripheral Artery Disease III: Interprofessional Care

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...

Arteries of the Upper Limbs

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
