心脏移植后急性血管排斥反应.炎症反应存在大量的淋巴细胞,主要围绕在小动脉周围,成为血管炎。移植后数月免疫抑制剂剂量减少时就会发生。这样的病人增加免疫抑制剂的治疗不如急性细胞性排斥反应那么有效。
This is acute vascular rejection in a heart transplant. The inflammatory reaction consists mostly of lymphocytes and is seen mainly around small arteries, a vasculitis. Such a reaction can occur when the dose of immunosuppressive drugs is decreased in the months following transplantation. Increasing immunosuppresive therapy in these patients is not as effective as for acute cellular rejection.
