Improved visualization of aortopulmonary collateral arteries by abdominal aortic compression during angiography.
Increased filling of aortopulmonary collateral arteries occurs when the descending aorta is obstructed distal to their origin. We used this fact to develop a simple, safe technique for improving angiographic visualization of these arteries. The abdominal aorta is manually compressed against the spine during injection of contrast medium. A slight reflex bradycardia resulted, which probably also ...
متن کاملPrenatal diagnosis of major aortopulmonary collateral arteries.
BACKGROUND The presence of foetal major aortopulmonary collateral arteries (MAPCAs) is associated with adverse outcome, therefore early diagnosis is essential. AIM To evaluate the usefulness of foetal echocardiography in the diagnosis and evaluation of MAPCAs in foetuses with pulmonary atresia, as well as to assess the effects of prenatal diagnosis on the management of neonates with pulmonary...
متن کاملPulmonary atresia, "intact ventricular septum", and aortopulmonary collateral arteries.
In muscular pulmonary atresia, major aortopulmonary collateral arteries are characteristic of pulmonary atresia with ventricular septal defect and are rarely seen in pulmonary atresia with intact ventricular septum. Two unusual cases of muscular pulmonary atresia are reported, one with an intact septum and one with a perimembranous ventricular septal defect, closed in utero by aneurysmal tricus...
متن کاملRole of magnetic resonance angiography in the diagnosis of major aortopulmonary collateral arteries and partial anomalous pulmonary venous drainage.
BACKGROUND Accurate diagnosis of major aortopulmonary collaterals (MAPCAs) and partial anomalous pulmonary venous drainage (PAPVD) in adult patients with congenital heart disease is important but problematic. Three-dimensional contrast-enhanced magnetic resonance angiography (MRA) provides a minimally invasive technique to allow detailed studies in a single breath-hold. METHODS AND RESULTS We...
متن کاملAortopulmonary collateral arteries: a rare complication after arterial switch operation for transposition of the great arteries
Collateral vascular arteries from the descending aorta to the pulmonary arteries are uncommon after arterial switch operation. Here, we report the case of a baby girl treated with coil embolization for abnormal blood flow from the descending aorta to the pulmonary arteries after arterial switch operation. A baby girl weighing 1324 g was delivered at 32 weeks 4 days of gestation, and she had D-t...
