Title: Vasculitis Poster III
Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose:
Hemoptysis is the most frequent and feared symptom of pulmonary artery involvement (PAI) in Behçet’s syndrome (BS). Some BS patients with PAI experience recurrent hemoptysis after achieving clinical response and regression or even resolution of abnormal radiologic findings with treatment. Enlargement of bronchial arteries may be the source of recurring hemoptysis in these patients.
Methods:
Retrospective chart review of 6 BS patients (all men) having repeated hemoptysis with no overt clinical or radiologic findings for active PAI.
Results:
The mean age of the patients at the diagnosis of PAI was 28.8± 5.8 SD years and their mean disease duration was 2±1.5 SD years. Five patients had pulmonary artery aneurysms (PAA) and 1 had pulmonary artery thrombosis (PAT). Consolidation treatment consisted of monthly cyclophosphamide pulses and corticosteroids (1.7±1.2 mean±SD years) and this was followed by maintenance with azathioprine. This treatment was successful in ameliorating hemoptysis in all patients except 1 PAA patient who experienced gross hemoptysis necessitating pulmonary artery embolization 2 years later. Hemoptysis recurred in all after a mean interval of 5.8±6.2 SD years (range 1 – 17 years). Thorax CT evaluations did not show any signs for new or worsening of existing PAI. Rather, there was complete resolution of PAA in 4 patients, regression of PAA in 1 patient and regression of PAT in 1 patient. However, enlargement of bronchial arteries and enlarged collaterals were evident in 5 patients. Four of them underwent transcatheter bronchial artery embolization that was complicated by hemiparesis in 1 patient. This procedure was repeated in 1 patient 2 years later because of new enlarged epigastric arteries. This patient still continues to experience occasional and small hemoptysis 3 years after the last procedure. The other 3 patients are currently free of hemoptysis ranging for between 3 months and 8 years after the procedure. The fifth patient died of massive hemoptysis in emergency unit in another center before undergoing embolization. His last CT did not show any evidence of PAI. The source of bleeding could not be demonstrated in the last patient despite repeated bronchoscopies and pulmonary angiography who is now completely symptom free since 4 years and does not take any medications either.
Conclusion:
Enlargement of bronchial arteries and formation of collaterals can complicate the course of PAI during remission and may result in recurrent and potentially fatal hemoptysis in BS patients. Whether this enlargement is only due to the compromised pulmonary circulation or there is also accompanying vasculitis remains to be studied. Transcatheter embolization appears to be successful in controlling hemoptysis in such patients.
