Massive cryptogenic hemoptysis undergoing pulmonary resection: clinical and pathological characteristics and management.

Massive cryptogenic hemoptysis is a common presenting symptom and cause of hospitalization for respiratory diseases, and represents a challenging condition in the clinical. This study aimed to analyze the clinical and pathologic data and management of patients with massive cryptogenic hemoptysis. We retrospectively reviewed 12 patients with massive cryptogenic hemotysis in our hospital between January 2003 and December 2012. Bronchoscopy showed submucosal vascular abnormalities in 4 patients. Of 6 patients managed with conservative measures, bleeding was completely controlled in 2 patients. Of 10 hemoptysis patients, three were controlled by bronchial arterial embolization, and seven by surgery. Pathological examination showed a superficial dysplastic, tortuous and dilated bronchial artery under the bronchial epithelium in 4 patients, and bronchiole dilation in 2 patients, indicating Dieulafoy's disease of the bronchus and bronchiectasis. No malignance developed within the follow-up. In conclusion, Dieulafoy's disease of the bronchus and bronchiectasis should be suspected in patients with massive cryptogenic hemoptysis. BAE and surgical treatment should be considered in case that massive hemoptysis could not be controlled by conservative management.
