Thrombotic Microangiopathy and Venous Thrombosis in a Patient With Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a systemic pauci-immune small vessel vasculitis. Its various presentations make AAV diagnosis challenging. Here, we present a case of AAV with thrombotic microangiopathy (TMA) and deep venous thrombosis (DVT).
