Příklady arch

• In four patients, it was placed through the brachiocephalic artery permitting selective perfusion of the brain during repair of the aortic arch.

• Migrating crest cells could be followed through the pharyngeal arches and the somites targeting to the arterial ostium level and the sinuatrial region.

• Here, an approach is developed specifically to the study of arches and vaults.

• Furthermore, in specimens with coarctation, the proximal aortic arch contained fewer elastic lamellae than specimens without coarctation.

• The pulmonary veins, left atrium and aortic arch are clearly seen.

• This final segregation was more apparent in the second and third gill arches.

• The interruption is located between the ascending aorta and proximal portion of the aortic arch.

• The ascending aorta was bulbous, but narrowed at the transverse arch and at the site of repair of the aortic coarctation.

• The proximal portions of the sixth arches contribute to the pulmonary arteries and the distal portions of the left sixth arch becomes the arterial duct.

• Recent investigations showed that cells from the cardiac neural crest contribute to the formation of the arch arteries and the media of the arch.

• More rarely the supply can be via an aortopulmonary window, the fifth aortic arch, or fistulas between the coronary and pulmonary arteries.

• This projection identifies ventricular morphology and the ventriculoarterial connection and shows the aortic arch and the bifurcation of the pulmonary arteries.

• The aortic arch itself was interrupted between the left common carotid and the left subclavianan arteries.

• The long and narrow passage is evenly lit by a continuous glazed roof with open spandrel arches that provide a good level of daylight.

• Although rare, the possibility of cervical aortic arch and intrathoracic vascular pathology should be considered in patients with a large facial hemangioma.
