[Value of thoracic CT in the management of severe hemoptysis]

Abstract

Purpose: To assess the value of thoracic CT in the management of patients with severe hemoptysis.

Patients and methods: Between January 1997 and January 2001, 62 patients were investigated for severe hemoptysis (>300 ml/24H). The protocol, performed before angiography and embolization, included bronchial fiberoptic examination (BFE) followed by thoracic spiral CT-angiography. Data recorded at CT and BFE were the presence and location of bleeding, the etiology of hemoptysis and the therapeutic modality.

Results: Nine patients with life-threatening hemoptysis directly underwent bronchial embolization. CT was available in the 53 remaining patients. No abnormality was found in 4 patients. CT assessed the presence (n=49) and the location (n=38) of the bleeding. The etiology was determined in 49 patients. BFE was feasible in 38/53 patients. BFE assessed the presence (n=38) and location (n=15) of the bleeding. The etiology was determined in 12 cases of bronchial tumour. The available findings of CT and BFE for the presence and the location of the bleeding were concordant. Comparing fiberoptic examination and thoracic CT, the percentages of localized bleedings (39% and 72%) and demonstrated etiologies (32% and 92%), were significantly different (p<0,005 and p<0.0001 respectively).

Conclusion: Although retrospective and limited by the small number of cases, our study provides arguments to perform thoracic CT before bronchial fiberoptic examination for the management of severe hemoptysis.
