Little is known about the strength of suture lines and stapled closures of the bronchus, pulmonary arteries, and pulmonary veins. This experiment tested and compared the hydrostatic leakage point of each of these structures when closed by either sutures or staples. Fourteen fresh mature porcine cadavers and 8 human cadavers ...

An infant with complete atrioventricular septal defect (atrioventricular canal) was examined by standard transthoracic two-dimensional pulsed Doppler and color Doppler echocardiography. No evidence of ductus arteriosus was present. Preoperative transesophageal echocardiography identified a patent ductus: the left-to-right shunt seen by color Doppler echocardiography was enhanced by pharmacologic maneuvers aimed at ...

Six electrical workers accidentally exposed to degradation products of sulphur hexafluoride (SF6) during electrical repair work were followed up for one year. One degradation product, sulphur tetrafluoride (SF4), was identified from worksite measurements. Unprotected exposure in an underground enclosed space occurred for six hours over a 12 hour period. Initial ...

A 54-year-old woman with unoperated patent ductus arteriosus developed fatal cardiac tamponade due to a dissecting aneurysm of the pulmonary artery causing haemopericardium. Histology of the pulmonary artery showed the presence of cystic medial necrosis. Previous reports of this condition are reviewed and the role of pulmonary hypertension causing secondary ...

A novel percutaneous patent ductus arteriosus (PDA) occlusion technique, without the potential problems associated with conventional techniques, has been long awaited. The development of a novel transvenous PDA occlusion technique using a temperature-shape changeable occluder device, and the verification of its in vitro performance, were demonstrated in this study. The ...

A 3-month-old boy, mildly cyanosed and tachypneic, was found by cineangiography to have a nonbranching main pulmonary artery arising from the right ventricle and connecting to the descending aorta via a large persistent ductus arteriosus. The left and right pulmonary arteries arose as a common "trunk," before branching, from the ...

Vascular anomalies of the middle ear are extremely rare. The most common anomaly is a persistent stapedial artery. This artery is important clinically because of the risk of profuse bleeding during middle ear surgery. We describe a 26-year-old woman with a glomus tympanicum tumor. The blood supply to the tumor ...

Our 100% mortality rate with first-stage palliation of hypoplastic left heart syndrome performed with cardiopulmonary bypass led us to a procedure not necessitating bypass. In nine neonates with this congenital heart defect, a woven Dacron graft was placed from the main pulmonary artery to the descending thoracic aorta. The patent ...

Prenatal diagnosis of tetralogy of Fallot by two-dimensional echocardiography, which is based on demonstration of a ventricular septal defect and a large overriding aorta, is difficult. In the majority of cases the main pulmonary artery is small. In utero, there is no pathologically increased degree of the physiological right-ventricular hypertrophy. ...
