What is the first branch off the aortic arch?

brachiocephalic artery


Is the brachiocephalic artery longer on the left side than on the right?

Trick question.... you only have 1 brachiocephalic trunk. It comes off the right side of the aortic arch (right side from anatomical position, or the patient's perspective) and immediately splits into the subclavian artery and the common carotid artery. On the left side of the arch the subclavian and common carotid branch directly off the aortic arch. Hopefully this makes sense.

Aortic arch syndrome?

DefinitionAortic arch syndrome refers to a group of signs and symptoms associated with structural problems in the arteries that branch off the aortic arch. The aortic arch is the top part of the main artery carrying blood away from the heart.Alternative NamesSubclavian artery occlusive syndrome; Carotid artery occlusion syndrome; Subclavian steal syndrome; Vertebral-basilar artery occlusive syndromeCauses, incidence, and risk factorsAortic arch syndrome problems are most often associated with trauma, blood clots, or malformations that develop before birth. The arteries' defects result in abnormal blood flow to the head, neck, or arms.In children, there are multiple types of aortic arch syndromes, including:Congenital absence of a branch of the aortaIsolation of the subclavian arteriesVascular ringsSymptomsSymptoms vary according to the affected artery, but may include:Neurological changes such as: DizzinessBlurred visionWeaknessBlood pressurechangesBreathing problemsNumbness of an armReduced pulseTransient ischemic attacksTreatmentSurgery is usually required to treat the underlying cause of aortic arch syndrome.ReferencesWebb GD, Smallhorn JF, Therrien J, et al.

Where do coronary arteries originate in the heart?

The right coronary artery takes its blood supply from the right coronary sinus, just above the aortic valve and sprouting from the ascending aorta. The left coronary artery takes its blood supply from the left coronoray sinus, also coming off of the ascending aorta. From these main coronary arteries, the rest of the branch coronary arteries are derived.
