lished treatment for hemoptysis (1-4). For complete embolization as well as to avoid embolization on a non-target organ, precise knowledge of the anatomy of the bronchial artery is important (5-7 ) . We describe a case in which an aberrant bronchial artery from left common carotid artery, communicating with the left bronchial artery, found during embolization of the bronchial artery, was a pote...

We previously found that injection of 15-μm microspheres into the bronchial artery of sheep decreased bronchial artery resistance. This effect was inhibited partially by indomethacin or 8-phenyltheophylline, suggesting that microspheres caused release of a dilating prostaglandin and adenosine. To identify the prostaglandin and confirm adenosine release, we perfused the bronchial artery in anest...

unilateral pulmonary artery agenesis (upaa) is a rare congenital anomaly during the 4 th  week of gestational age. it is defined as an absence of pulmonary parenchyma and its supporting artery. a 9-year-old girl was admitted to our hospital because of chronic cough. chest examination showed a decrement in lung sound of right hemi-thorax with expiratory wheeze. chest radiography (cxr) revealed a...

The effects of bronchial arterial administration of vasoactive substances on the pulmonary circulation were studied by a new technique for selective catheterization of a bronchial artery in intact dogs. In most experiments, this technique permitted pressor agents to be distributed mainly to one lung with smaller amounts to the other lung. The intercostal arteries were avoided, and in all but 2...

Bronchial artery embolization is an effective nonsurgical therapy for massive hemoptysis. Routine selection of the bronchial arteries from the aorta usually enables the interventionalist full interrogation and embolization of the culprit vascular abnormality. In problematic cases where bronchial artery access is difficult, a systemic-to-pulmonary arterial shunt can be exploited as a retrograde ...

A bronchial artery aneurysm (BAA) is uncommon and usually associated with chronic inflammatory lung disease or a systemic vascular condition, which is rarely the etiology of mediastinal hemorrhage. A middle-aged person presented with spontaneous hemothorax and hemomediastinum. A diagnostic evaluation identified a bronchial artery aneurysm as the source. To prevent further rupture, we performed ...

A coronary-bronchial artery fistula is a very rare congenital anomaly of the coronary artery whose etiology and pathogenesis have not yet been clarified. Most patients with coronary-bronchial fistulas are asymptomatic; however, some patients present with congestive heart failure, infective endocarditis, myocardial ischemia induced by a coronary steal phenomenon, or rupture of an aneurysmal fist...

Management of cryptogenic massive hemoptysis is difficult, and conservative treatment may be inadequate to stop the hemorrhage. Surgery is not a reasonable option because there is no underlying identifiable pathology. This study aimed to investigate the radiologic findings and bronchial artery embolization outcomes in cryptogenic hemoptysis, and to compare the results with non-cryptogenic hemop...
