Endovascular stent implantation for isolated pulmonary arterial stenosis caused by Takayasu’s arteritis
Takayasu’s arteritis (TA) is an idiopathic large-vessel vasculitis of young adults that causes stenosis and/or aneurysmal dilatation of the aorta and its major branches . Although the pulmonary artery is often (50–80% of cases) involved in TA, the isolated pulmonary TA is really uncommon . We present a case of isolated pulmonary TA, and describe the successful endovascular therapy and prognosis of this rare condition.
A 40-year-old female presented with a history of progressively increasing dyspnea on exertion for one and a half years. At the time of presentation, she was in New York Heart Association class III. There was nothing remarkable in her routine blood-sample tests other than mildly increased C-reactive protein (CRP) (3.0 mg/dL) and erythrocyte sedimentation rate (ESR) (22 mm at the first hour). Rheumatoid factor and antinuclear antibody were both negative. Chest X-ray films showed no marked abnormality. Electrocardiogram showed no axis deviation....
