Clinical characteristics and treatments for bronchial Dieulafoy's disease.

BACKGROUND

Dieulafoy's disease of the bronchus is an arterial abnormality characterized by enlarged mucosal arterial branches that are susceptible to lethal bleeding. To date, this disease is rarely reported in the literature. We recently encountered three patients from February 2010 to March 2017, each with such a vascular anomaly in a bronchus with massive hemoptysis.

AIM

This paper describes the clinical characteristics and treatments for Dieulafoy's disease.

METHODS

We report three cases with recurrent massive hemoptysis. Bronchoscopic examination was performed on two patients, one with a non-pulsating polypoid nodule and the other without. One patient had fatal bleeding after biopsy and could not withstand bronchial artery embolization or thoracotomy. Angiography and bronchial artery embolization on another two patients successfully stopped the bleeding. In addition, we retrospectively reviewed the literature on all reported cases with cryptogenic hemoptysis, obtained through PubMed and Chinese journal searches.

RESULTS

The intervention with embolization was successful, and no new episodes of acute hemoptysis were observed.

CONCLUSION

Angiography can be used for diagnosis of Dieulafoy's disease of the bronchus, whereas bronchoscopy biopsy should be avoided. Interventions such as embolization or bronchial coagulation play an important role in patients with coughing with massive hemoptysis.
