title: 64-detector row CT evaluation of bronchial and non-bronchial systemic arteries in life-threatening haemoptysis.
abstract: OBJECTIVE
  To retrospectively evaluate the depiction of bronchial and non-bronchial systemic arteries with 64-detector row CT in patients undergoing endovascular treatment for life-threatening haemoptysis.
  
  
  METHODS
  64-detector row helical CT and conventional angiography of the thorax were performed in 28 patients (25 males, 3 females; age range, 18-65 years; mean age, 40 years) with life-threatening haemoptysis. CT images were analysed to identify abnormal bronchial and non-bronchial systemic arteries and also to localise them in two planes.
  
  
  RESULTS
  Using multidetector CT (MDCT), 43 bronchial arteries were identified on the right side and 46 on the left side. 89% of the right bronchial arteries originated from the right intercostobronchial arteries. A common trunk of origin of the right and left bronchial artery was noted in 46% of cases. 23 non-bronchial systemic arteries were noted on the right side and 41 on the left side. Pleural thickening >3 mm was confirmed to be a good predictor of non-bronchial systemic supply. An internal mammary artery diameter of >3 mm and an inferior phrenic artery diameter of >2 mm were sensitive indicators for non-bronchial systemic supply.
  
  
  CONCLUSIONS
  MDCT is a good investigation tool for evaluating life-threatening haemoptysis as it confirms the disease process, identifies the origin and ostial position of bronchial arteries, detects non-bronchial systemic arteries and acts as a roadmap for percutaneous transcatheter embolisation.
