Takayasu’s disease (nonspecific aortoarteritis) is a granulomatous inflammation of the aorta and its main branches with a progressive course and development of severe ischemic disorders. The difficulty of diagnosis and the possibility of applying various methods of pathogenetic anti-inflammatory treatment of Takayasu’s arteritis make it expedient to study a clinical case. The analysis of a clinical case of a patient with Takayasu’s arteritis with manifestation of the disease in the form of general inflammatory syndrome and manifestations of severe cerebral ischemia due to bilateral stenotic carotid artery lesion was performed. The patient has been under observation since September 2017 up to the present time, various methods of pharmacotherapy and surgical correction were used in her therapy. The dynamics of clinical symptomatology of Takayasu’s arteritis and clinical results of step therapy with high doses of methylprednisolone, bolus administration of cyclophosphan followed by long-term oral cyclophosphan administration were analyzed. In the course of treatment, the patient underwent carotid angioplasty. Due to the unstable effect of the therapy, the patient was administered intravenous infusions of IL-6 blocker tocilizumab, which led to remission of the disease. The presented clinical case demonstrates the important diagnostic value of vascular imaging methods in early diagnosis and control of the disease course and the effectiveness of IL-6 inhibitors in achieving and maintaining remission of Takayasu’s arteritis.
