Surgical repair of pulmonary artery dissection in a patient with 10-year history of Takayasu's arteritis.

Pulmonary artery (PA) dissection is a rare but life-threatening event, predisposing to sudden cardiac death and cardiogenic shock, and generally occurs in patients with underlying pulmonary hypertension. We report a case of surgical repair of PA dissection in a patient with 10-year history of Takayasu’s arteritis and with no diagnosis of pulmonary hypertension.
