A 40-year-old man who underwent total hip replacement on the left side with a metal-on-metal (MOM) implant reported swelling at the operative site within 6 weeks of the arthroplasty. Tissue sampled during the revision arthroplasty showed an aseptic lymphocyte-dominated vasculitis-associated lesion (ALVAL).
ALVAL is a widely recognized complication of MOM hip implants and needs to be considered early, even in completely asymptomatic patients with normal metal ion levels and normal radiographs.
一名40岁男性接受了左侧全髋关节置换术，使用金属对金属（MOM）植入物，在关节置换术后6周内报告手术部位肿胀。翻修关节置换术期间采集的组织显示为无菌性淋巴细胞为主的血管炎相关病变（ALVAL）。
ALVAL是MOM髋关节植入物广泛认可的并发症，即使在金属离子水平正常且X线片正常的完全无症状患者中，也需要早期考虑。
