概括
系统性免疫抑制并没有显著影响慢性四肢威胁性缺血症 (CLTI) 下肢再血管化的患者的结果. 这包括移植的通透性,再干预率和重大截肢,无论手术类型如何.
科学领域:
- 血管外科 血管外科
- 免疫抑制疗法是一种免疫抑制疗法.
- 慢性四肢威胁性缺血症 (CLTI) 是一种疾病.
背景情况:
- 许多患有CLTI的患者由于并发症需要全身免疫抑制.
- 免疫抑制对下肢再血管化结果的影响尚未得到充分证实.
- 潜在的作用包括抑制移植体的整合或预防炎症/残留症.
研究的目的:
- 评估系统性免疫抑制与不免疫抑制对CLTI首次下肢再血管化后的结果的影响.
- 为了比较绕道移植 (BPG) 和皮肤透光血管造形术 (PTA/S) 程序之间的结果.
主要方法:
- 对1312名首次接受CLTI下 inguinal BPG或PTA/S的患者进行了回顾性分析 (2005-2014).
- 根据免疫抑制状态分层的患者 (干预时治疗≥6周).
- 主要结局:经手术后的并发症,再干预,初级通透性,肢体救援. 使用卡普兰-梅尔和考克斯回归模型进行分析.
主要成果:
- 在接受免疫抑制治疗的BPG患者的术后结果或3年后的结果 (重新干预,初级通透性,主要截肢) 没有显著差异.
- 对于PTA/S患者,单变量分析显示免疫抑制组的截肢率较高 (23%对12%,P=.01).
- 多变量分析 (Cox回归) 没有发现免疫抑制和重新干预,重大截肢或BPG或PTA/S.的初级通透性之间的显著关联.
结论:
- 系统性免疫抑制对CLTI下肢再血管化后的晚期结果 (初级通透性,再干预,主要截肢) 没有显著影响.
- 这些发现适用于旁路移植和皮肤透光血管造形手术.
- 免疫抑制状态不应成为CLTI患者再血管化的禁忌.

Peripheral Artery Disease III: Interprofessional Care
11
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...

Tissue Transplantation
394
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
