The authors present the results of selective bronchial and parietal arteriography of pulmonary systemic hypervascularization, in 83 cases. They emphasize the advantages of previous pulmonary venous angiography and overall aortography for the success of selective injections. Failures are evaluated at 6 to 7%. On occasions, a medullary branch was opacified. No medullary accidents were noted. The angiographic appearances of the lesions encountered are described. A comparative study of the angiographic results of non-tumoral acquired lesions was carried out in those patients with hemoptysis and in those who were free from them.

[The treatment of hemoptysis by embolization of the systemic arteries (author's transl)].

The authors present their still limited experience of embolization of systemic arteries as the treatment of hemoptysis. Their cases illustrate the indications, contra-indications, causes of failure and effectiveness of this therapeutic method in pneumology. They had to refuse who patients: in the first, the pathological bronchial artery arose from a common trunk with the intercostal which gave rise to an anterior spinal artery. The second patient showed signs of medullary involvement on injection of a pathological right intercostal artery, which in their opinion is also a contra-indication of embolization, although no anterior spinal artery was demonstrated on the arteriogrammes. Six patients were treated by embolization. In the case of one patient, treatment was a failure owing to incomplete embolization. A main esophageal pedicle supplied a high flow bronchial artery anastomosis. These important collateral esophageal vessels compromize the effectiveness of bronchial embolization.
