[Isolated abdominal pain revealing a paraprosthetic fistula in a patient with Takayasu arteritis]. / Douleur abdominale isolée révélant une fistule paraprothétique au cours d'une maladie de Takayasu.

Aortic aneurysms and stenosis occurring in Takayasu arteritis may require aortic prosthesis that can be complicated by aorto-digestive fistula. We report a 41-year-old female who presented with an isolated abdominal pain revealing a para-prosthetic aorto-duodenal fistula complicating a Takayasu arteritis. The diagnosis of aorto-digestive fistula may be difficult if abdominal pain is isolated and imaging inconclusive. Surgical procedure may be necessary to obtain the diagnosis and constitutes the main part of the treatment before fatal outcome.
