    Abstract:
    Hemoptysis is a life-threatening complication of Behcet's disease that is likely related to pulmonary artery aneurysm (PAA). Vascular interventional radiology may offer effective emergency therapeutic option, but has not been thoroughly investigated in this setting. A case series of a French referral center for hemoptysis combined with a literature review of case reports was conducted. Between 1995 and 2016, 12 patients were referred to our center for hemoptysis revealing or complicating the course of Behcet's disease. Pulmonary artery aneurysm (PAA) was the mechanism of hemoptysis in ten patients, nine of whom were treated by a transcatheter embolotherapy. Combining an additional 8 case reports from the literature, 17 patients treated by transcatheter embolotherapy for PAA were analyzed. The duration of the course of Behcet's disease was 22 months [IQR 3-45] at the time of PAA diagnosis. Transcatheter embolotherapy of PAA was successful for immediately controlling hemoptysis in all patients, without major complication except for one. Hemoptysis recurred in seven patients (41%) within 5 months [IQR 1-12]. The use of coils for transcatheter embolotherapy was associated with hemoptysis recurrence. A bronchosystemic hypervascularization related to the previously occluded PAA was the main mechanism of bleeding recurrence, leading to bronchosystemic artery embolization in four patients and surgery in two patients. Behcet's disease-related hemoptysis is mainly due to PAA. Transcatheter embolotherapy should be considered as the first-line emergency treatment for PAA-related hemoptysis, in association with the immunosuppressive regimen. Hemoptysis may recur in half of the cases, involving preferentially a bronchosystemic arterial mechanism.
