Graft Choice and Timing of Coronary Bypass Surgery in Patients with Vasculitis Syndromes: Two Cases Report

Abstract
Polyarteritis nodosa is multisystem disease with necrotizing vasculitis of middle and small sized arteries. Takayasu arteritis is a rare nonspecific inflammatory disease with unknown cause, predominantly affecting the aorta and its main branches. In the literature, experience about the appropriate graft selection and the long-term patency is reported for vasculitis syndromes such as Takayasu’s arteritis but there were no data for Polyarteritis Nodosa. In this article we review the graft choice for patients with vasculitis syndromes and our coronary revascularization surgery experience with two patients, one with Polyarteritis Nodosa and the other with Takayasu’s arteritis. There has not yet a consensus on graft choice for patients with vasculitis syndromes and it will be possible more accurate assessment if the number of cases increases.
