METHOD MODELING pathological tortuosity of the internal carotid artery in experimental animals

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, particularly to vascular surgery and can be used in experimental surgery. It involves an extensive sympathectomy of the common, internal and external carotid arteries by removing their adventitial coats. The common carotid artery is fixed to a medial edge of the fascial compartment of the sternocleidomastoid muscle. At the level of occipital vessels between two ligatures, the external carotid artery is transected, and within a bifurcation point of the common carotid artery, two clamps are applied on the internal carotid artery. The lower clamp is placed along an extension line of a lateral edge of the external carotid artery, while the upper clamp - transversally and in between; the internal carotid artery is transected; anastomosis of a distal end of the internal carotid artery with a proximal end of the external carotid artery is created, and pathological sinuation of the internal carotid artery is formed.;EFFECT: method extends the range pf products for simulating pathological sinuation of the internal carotid artery in experimental animals.;1 ex
