The inaccuracy of measuring human bronchial artery blood flow has previously been considerable. En bloc double-lung transplantation with bronchial artery revascularization (BAR) using a single conduit offers the unique opportunity of direct measurement of the total bronchial artery blood flow. In eight en bloc double-lung-transplanted patients with complete BAR, the basal blood flow was measure...

OBJECTIVE To examine the efficacy and safety of bronchial artery embolisation in patients with acute major haemoptysis and those with chronic recurrent haemoptysis. DESIGN Retrospective review of clinical records. SETTING Regional hospital, Hong Kong. PATIENTS Clinical records of 70 consecutive patients who had undergone bronchial artery embolisation in Queen Elizabeth Hospital from 1998 ...

Transcatheter embolization is the first-line treatment for massive hemoptysis and recurrent intractable hemoptysis. Proximal interruption of the pulmonary artery is a rare congenital anomaly characterized by hypertrophy and neovasculsarity of bronchial and nonbronchial aortopulmonary collaterals; hemoptysis complicates a minority of cases. We present a case of unilateral proximal interruption o...

Bronchial compression due to pulmonary artery dilation is an important problem in infants with congenital heart disease, and can complicate the postoperative course. In recent years, airway stenting has become a popular treatment for these cases. We achieved success with endobronchial stenting in a two-month-old infant with bronchial compression caused by a dilated pulmonary artery.

Smoke inhalation can produce acute pulmonary edema. Previous studies have shown that the bronchial arteries are important in acute pulmonary edema occurring after inhalation of a synthetic smoke containing acrolein, a common smoke toxin. We hypothesized that inhalation of smoke from burning cotton, known to contain acrolein, would produce in sheep acute pulmonary edema that was mediated by the ...

Angiotensin-converting enzyme (ACE) plays a major role in the metabolism of bradykinin, angiotensin, and neuropeptides, which are all implicated in inflammatory airway diseases. The activity of ACE, which is localized on the luminal surface of endothelial cells (EC), has been well documented in pulmonary EC; however, few data exist regarding the relative activity of ACE in the airway vasculatur...

The lung transplant community has long ignored the importance of bronchial arterial blood supply. We review relevant history, published articles addressing post-transplant ischemia, and single-center reports with artery revascularization (BAR), followed by details surgical technique. In our experience, although BAR requires cardiopulmonary bypass (CPB) there is increased risk bleeding, ischemic...
