白塞病是一种原因不明的慢性多系统血管炎,可累及各种大小的动脉和静脉,表现为动脉瘤形成和动、静脉闭塞。其中肺动脉瘤虽不多见,但因其有易破裂倾向,对生命危害很大。皮质类固醇及免疫抑制剂对累及血管的白塞病有很好的疗效。作者报道了13例有肺动脉瘤的白塞病(皆为男性,17～44岁,均进行了药物治疗,其中2例因大咯血做了肺切除术。在治疗前后作了螺旋CT扫描,观察了动脉瘤的 Behcet’s disease is an unidentified chronic multisystem vasculitis that can involve various sizes of arteries and veins, manifesting as aneurysm formation and arterial and venous occlusion. Although pulmonary aneurysms are rare, but because of their tendency to rupture, life-threatening great. Corticosteroids and immunosuppressive agents have a good effect on Behcet’s disease involving blood vessels. The authors reported Behcet’s disease in 13 patients with pulmonary aneurysms (all men, 17-44 years old, both treated with drugs, 2 of whom underwent pneumonectomy due to massive hemoptysis.) Spiral CT scans were performed before and after treatment Aneurysms
