背景情况:

患有连接组织疾病和大动脉根动脉瘤的患者面临剖析和扩张进展的风险.
传统的治疗方法,如全额或门节约性根部置换,存在一些缺点,包括抗凝的需要和重新操作的风险.
个性化外部大动脉根支 (PEARS) 是一款旨在减轻这些风险的新型周血管支架.

研究的目的:

评估PEARS程序的安全性和有效性.
报告荷兰第一个90名结合组织疾病和大动脉根动脉瘤患者的结果.

主要方法:

在2018年1月至2023年2月期间,共有90名患者接受了孤立的PEARS,罗斯-PEARS或同时进行的PEARS手术.
程序通常在诱导的低血压下进行离.
评估了手术前和手术后的成像 (心声,CT/MRI) 和患者的特征.

主要成果:

手术成功率为96.6%,两次转换为常规手术.
在随访期间 (中位数为6个月) 没有死亡,内心炎或解剖发生.
手术后观察到主动脉根和上升主动脉直径的显著减少.

结论:

皮尔斯手术证明了可接受的手术风险,是大动脉根动脉瘤治疗的可行替代方案.
在随访期间没有发现任何剖析,这突显了关键的安全益处.
与冠状动脉起源相关的潜在并发症需要仔细考虑.
