Objective: The aim of our study was to evaluate the role of thoracic MDCTA in the management of acute hemoptysis secondary to pulmonary artery injuries.
Materials and Methods: During a 14-month period (08/2004 to 09/2005), 119 patients were admitted in respiratory intensive care unit for hemoptysis. MDCTA was performed in 112 patients prior to endovascular treatment. eighty five patients underwent an endovascular treatment.
Results: Hemoptysis was secondary to pulmonary arteries injury in five patients (5/85:6%). They were 3 men, and 2 women, mean age 45.8 years. Causes of pulmonary artery involvement were identified on MDCTA as active tuberculosis (n= 2, false aneurysm), Behçet disease (n=2, pulmonary artery aneurysm, bronchial and non bronchial systemic hypervascularization), and necrotic squamous cell carcinoma (n=1, false aneurysm). Pulmonary arteries vaso-occlusion was performed in 3 patients without bronchial angiography (active tuberculosis “n=2”, Behçet disease ”n=1”), in one patient it was associated with bronchial artery vaso-occlusion in the same session (Behçet disease). In the last one, vaso-occlusion was performed one week after bronchial artery vaso-occlusion (squamous cell carcinoma).
Conclusion: Multidetector row helical CT-angiography prior to endovascular treatment allows correct identification and early appropriate patients management with hemoptysis from pulmonary artery origin.
