Abstract

Purpose of review: Allograft vasculopathy in vascularized composite allografts (VCA) remains understudied. This review explores the vascular changes in VCA, focused on recent literature.

Recent findings: Allograft vasculopathy in VCA generally includes progressive concentric myointimal thickening and luminal narrowing of arterial vessels through endothelial deterioration and proliferation of smooth muscle cells. Microvascular changes are also noted, with thrombosis and lumen narrowing in microvessels of the skin even in the absence of large vessel vasculopathy. Histopathologic reports of skin containing VCA rejection document arteriosclerosis in deep vessels that are not always reflected in skin punch biopsies. The first revision of the Banff VCA scoring system 2022 was developed to include vascular changes in VCA. The scoring system for chronic changes and antibody mediated rejection continues to be under development.

Summary: The study of vascular changes in VCA continues to progress. Important data and advances in experimental and clinical VCA have been reported and continue to take place. Challenges ahead include capture of clinical data that will evolve beyond transient report forms and approaching on the problem of graft failure well grounded in sound scientific methodology.

血管化复合异体移植中的血管变化。
审查目的:血管化复合异体移植物(VCA)的血管病变仍未得到充分研究。这篇综述探讨了 VCA 的血管变化,重点关注最新文献:VCA中的同种异体移植血管病变通常包括通过内皮退化和平滑肌细胞增殖导致的动脉血管同心肌膜增厚和管腔狭窄。微血管也会发生变化,即使没有大血管病变,皮肤微血管也会出现血栓形成和管腔狭窄。含有 VCA 排斥反应的皮肤组织病理学报告显示,深层血管的动脉硬化并不总是能在皮肤打孔活检中反映出来。班夫 VCA 评分系统 2022 的首次修订版将 VCA 的血管变化纳入其中。慢性变化和抗体介导的排斥反应的评分系统仍在开发中。VCA 实验和临床方面的重要数据和进展已被报道,并将继续进行。未来的挑战包括获取临床数据,使其超越短暂的报告形式,并以健全的科学方法论为基础,解决移植失败的问题。
