概括

帕克利塔塞尔排泄支架 (PESs) 在5年后,即使在infrapopliteal病变中,也显示出延迟愈合和受损的内皮质化. 组织病理学证实了持续的问题,特别是在重叠的支架片段.

科学领域:

血管外科血管外科
干预心脏病学干预心脏病学
生物材料科学生物材料科学

背景情况:

在infrapopliteal (IP) 病变中对帕克利塔塞尔排泄支架 (PES) 的长期血管反应尚不清楚.
由于其复杂的解剖学和高风险的复杂性,IP病变具有挑战性.

研究的目的:

通过组织学来表征长期血管对PESs在infrapopliteal病变中的反应.
在植入后5年评估愈合过程和内皮细胞化.

主要方法:

一个78岁妇女的案例研究,患有关键四肢缺血症,接受重叠PES治疗.
在3岁和5岁时进行多模式成像 (OFDI,血管镜),然后在支架扩张后进行组织学分析.

主要成果:

在3岁时,观察到没有被覆盖的支架与血栓.
在5岁时,成熟的neointima存在于非重叠的部分,但未被覆盖的,纤维素涂层的支柱在重叠区域中持续存在.
组织病理学证实在重叠的支架段中延迟愈合和受损的内皮质化.

结论:

释放帕克利塔塞尔的支架可以导致下垂层病变的内皮质化受损.
在IP病变中重叠的支架放置可能会加剧延迟愈合和不完全的内皮质化.
长期组织学数据突出显示了复杂动脉段中与PES相关的潜在并发症.

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...
