METHOD FOR SELECTING THE SURGICAL MANAGEMENT OF THE ANEURYSM OF THE OPHTHALMIC SEGMENT OF THE INTERNAL CAROTID ARTERY WITH THE INVOLVEMENT OF THE OPHTHALMIC ARTERY IN THE ANEURISMIC STRUCTURE OR ASSOCIATED WITH IT Russian patent published in 2019 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to neurosurgery, neurology and ophthalmology. Initial neurologic symptoms and visual functions of the patient are assessed by the catheter balloon being inflated to the neck of the aneurysm; the balloon is inflated to complete cessation of blood flow in the internal carotid artery (ICA) and in the orbital artery (OA). Carotid angiography is performed to assess the presence of anastomosis between an orbital artery and branches of an external carotid artery. In the presence of anastomosis, a balloon-occlusion test is performed, evaluating neurological symptoms and visual functions in dynamics at preset intervals. If observing neurological symptoms, the functional significance of the internal carotid artery is considered to be high. Balloon-occlusion test is stopped and the flow-redirecting stent is installed. In the absence of neurological symptoms, the balloon-occlusion test is continued by evaluating visual functions in dynamics. If observing a visual impairment in a patient with visual disturbed vision in ophthalmoscopy, the functional significance of the ophthalmic artery is considered to be high. Balloon-occlusion test is stopped and the flow-redirecting stent is installed. If the patient observes vision loss during 45–50 minutes if observing a drop in vision, but ophthalmoscopy is normal, the ophthalmic artery is considered functionally insignificant and the aneurysm is switched off by spirals.

EFFECT: method enables individualizing an approach to surgical management of patients with aneurysms of the ophthalmic segment of the ICA with the involvement of OA in the aneurysm or associated structure, maximally reducing the probability of complications and reducing the cost of treatment.
