Abstract

Polytetrafluoroethylene (PTFE) graft is a synthetic graft commonly used in chronic haemodialysis patients. Expected complications of synthetic grafts include infection, thrombosis, oedema and pain. PTFE is a non-textile graft that is chemically inert, electronegative and hydrophobic. Due to their chemical properties, PTFE grafts have lower risks of these adversities. We present a patient with a rare case of cutaneous hypersensitivity to a PTFE graft.

摘要

聚四氟乙烯(PTFE)移植物是慢性血液透析患者常用的一种合成移植物。合成移植物的预期并发症包括感染、血栓形成、水肿和疼痛。PTFE是一种非纺织移植物,具有化学惰性、带负电荷且疏水。由于其化学性质,PTFE移植物发生这些不良反应的风险较低。我们报告了一例对PTFE移植物发生皮肤超敏反应的罕见病例。
