Preventing a central nervous system catastrophe in a case of Takayasu's arteritis presenting with critical stenosis of all three arch vessels.

Multifocal and bilateral involvement of the arch vessels is a common presentation of Takayasu's arteritis. Endovascular stenting of multiple supra aortic lesions in Takayasu's arteritis has been described scarcely in literature. We describe the management of a case of Takayasu's arteritis who presented with recurrent vertebro-basilar symptoms and a single surviving arch vessel. Whether routine revascularization of all three vessels is superior to symptom driven revascularization of individual lesions remains uncertain. The abundant collateral blood flow; the problems with stenting during the acute phase of the disease; the risk of restenosis that is considerably higher than atherosclerotic lesions; and the chances of progression of the disease have to be taken into account during endovascular revascularization of multiple supra aortic arch vessels.
