[Creation of extracranial-intracranial microvascular anastomosis under regional anesthesia (a case report and a review of the literature)].

The article describes a case of successful surgical treatment of an 81-year-old male patient with symptomatic occlusion of the internal carotid artery that led to severe impairment of cerebral hemodynamics and was accompanied by severe gait and equilibrium disorders. Given the patient's age and his positive medical history, he underwent surgery for the creation of an extracranial-intracranial microvascular anastomosis under regional anesthesia, with spontaneous breathing and a baseline level of consciousness being maintained. In the postoperative period, the patient achieved a marked clinical effect in the form of complete regression of syncopal conditions and gait disorders associated with recovery of cerebral perfusion in the right MCA territory. The article discusses the indications for surgical treatment and the technical details of surgery for the creation of an extracranial-intracranial microvascular anastomosis under regional anesthesia.
