Control of massive hemoptysis by embolization of bronchial arteries was achieved in two patients with bronchopleural fistula. Both patients would have been prohibitive risks for thoracotomy. The indications, contraindications, and technique of the procedure are presented as well as a review of the literature.

PURPOSE To report our experience with 10 cases of bronchial artery embolization (BAE). MATERIALS AND METHODS The study included 18 cases (11 men and 7 women between 21 and 81 years of age, average 52 years), whose massive hemoptyses could not be controlled with conservative and bronchoscopic methods and were sent to the digital subtraction angiography unit between August 2002 and May 2004. Of...

The relative contribution of the pulmonary and bronchial circulatory systems to heat and water exchange in normal lungs was evaluated in 20 isolated, in situ perfused dog lungs and in four patients undergoing elective cardiopulmonary bypass. In isolated dog lungs, if the pulmonary artery was perfused at a nominal flow rate (0.5 l/min), bronchial artery perfusion (up to 70 ml/min) did not signif...

• The existence of brouchopulmonary anastomoses has led to the general belief that the blood from the aorta and bronchial arteries can reach the pulmonary vessels and left atrium. There is reasonable evidence to suggest that the reverse can occur. Three observations pertain to the flow of blood from the pulmonary artery to the bronchial veins and right atrium: (a) In 1931 Berry and Daly perfuse...

Spontaneous mediastinal hematoma is exceedingly rare. We described such a case of a 61-year-old male with a posterior mediastinal hematoma from ruptured small aneurysm, which was ascertained via contrast-enhanced computed tomography examination. Subsequent super-selective angiography of left gastric artery revealed a ruptured aneurysm with contrast medium leakage, feeding vessels respectively f...

BACKGROUND Massive hemoptysis is a potentially life threatening respiratory emergency and mandates immediate investigation and intervention. There is no universal consensus regarding the optimal management of these patients, and there are no large series of patients studied. OBJECTIVES Here we reported thirty Iranian patients who were managed with bronchial artery embolization. PATIENTS AND...

BACKGROUND There is growing evidence to support bronchoscopic resection of well-circumscribed typical carcinoids. However, massive bleeding and risk of recurrence can potentially complicate this approach. OBJECTIVES The aim of this study was to assess the safety and feasibility of endobronchial resection of carcinoids preceded by bronchial artery embolization. METHODS Five patients with cen...

OBJECTIVE To characterize structural changes in pulmonary vessels of dogs with dirofilariosis. ANIMALS 8 dogs with dirofilariosis and 2 unaffected control dogs. PROCEDURE Pulmonary artery pressure was measured in affected dogs, and dogs then were euthanatized. Scanning electron microscopy was used to examine vascular corrosion casts of pulmonary vasculature. Tissue sections of pulmonary vas...
