| truncus arteriosus | <radiology> Right aortic arch (30-50%), VSD always immediately beneaath common truncal valve, waterfall or hilar comma sign (types II and III) TYPE, I short main pulmonary artery arises from left post-lat aspect, II pulmonary arteries arise separately from left post-lat aspect, III each pulmonary artery arises from lateral aspects, IV pulmonary arteries arise from dorsal aorta (pseudotruncus), probably tetralogy of Fallot with pulmonary atresia (12 Dec 1998) |
| truncus arteriosus communis | <radiology> Right aortic arch (30-50%), VSD always immediately beneaath common truncal valve, waterfall or hilar comma sign (types II and III) TYPE, I short main pulmonary artery arises from left post-lat aspect, II pulmonary arteries arise separately from left post-lat aspect, III each pulmonary artery arises from lateral aspects, IV pulmonary arteries arise from dorsal aorta (pseudotruncus), probably tetralogy of Fallot with pulmonary atresia (12 Dec 1998) |
| truncus arteriosus, persistent | A congenital anomaly resulting from the failure of the aorticopulmonary system to develop and divide the truncus arteriosus into the aorta and the pulmonary trunk. (12 Dec 1998) |
| truncus brachiocephalicus | The first and largest artery branching from the aortic arch. It distributes blood to the right side of the head and neck and to the right arm. (12 Dec 1998) |
| truncus bronchiomediastinalis | A lymphatic vessel arising from the union of the efferent lymphatics from the tracheo-bronchial and mediastinal nodes on either side.

| truncus costocervicalis | A short artery that arises from the subclavian artery on each side and divides into deep cervical and superior intercostal branches, the latter dividing usually to form the first and second posterior intercostal arteries. Synonym: truncus costocervicalis, costocervical artery. (05 Mar 2000) |
| truncus fascicularis atrioventricularis | The singular initial portion (stem) of the atrioventricular bundle which passes from the atrioventricular node into the right trigone of the fibrous skeleton of the heart and along the periphery of the membranous interventricular septum; upon reaching the muscular interventricular septum, the trunk terminates by dividing into the right and left crura of the atrioventricular bundle. Synonym: truncus fascicularis atrioventricularis. (05 Mar 2000) |
