Perioperative management of a patient with Henoch-Schonlein purpura for appendectomy.

Henoch-Schonlein purpura HSP is a multisystem disease and immunoglobulin A-mediated vasculitis with a self-limited course affecting the skin, joints, gastrointestinal tract, and kidneys. It is the most common form of acute small-vessel vasculitis primarily affecting children. Severe renal and central nervous system disease may lead to life-threatening conditions, and immunosuppressive agents and plasmapheresis may be needed. The cause of HSP is unknown; immunizations, certain food allergies, insect bites, infection, and some medications may play a role in the development of the disease. Perioperative management for liver and kidney functions is very important for anesthetized patients with HSP. We report the perioperative management of a patient with HSP for appendectomy.
