SYSTEMIC VASCULITIS WITH LESION OF LARGE VESSELS AS A CAUSE OF ART ERIAL HYPERT ENSION IN A PATIENT OF YOUNG AGE

Objective: to analyze and present a clinical case of late diagnosis of Takayasu’s arteritis in a young female patient with long-term arterial hypertension.

Materials and methods. The female patient G., born in 1989, had noted elevated arterial pressure (AP) of 150/90 mm Hg since she was 14. At 21 the following diagnosis was stated: Fibro-muscular dysplasia, stenosis of the left renal artery. Stenosis of the celiac trunk. Aneurisms of the branches of the superior mesenteric artery; prosthesis of the left renal artery was performed. Since the beginning of 2016, the patient has noted elevated AP of 200/110 mm Hg despite continuing hypotensive therapy. Diagnosis of Nonspecific aortoarteritis was proposed in May of 2017. Methylprednisolone therapy was administered: 250 mg No. 2 intravenously, Prednisolone: 25 mg a day orally. Due to signs of decreased blood flow to the left kidney, in August of 2017 extracorporeal repeat prosthesis of the left renal artery, bypass of the right middle renal artery with reversed autovein were performed.

Results. During examination in October of 2017, the patient complained of weakness, frequent elevated AP of 200/110 mm Hg. In blood test: hemoglobin 106 g/l, erythrocyte sedimentation rate 38 mm/h, C-reactive protein 25 mg/l. A heterozygous mutation in the methylenetetrahydropholate reductase, a heterozygous mutation in the factor V gene (G1691A) were identified. Homocysteine level was normal, infection and oncological pathology were excluded. The following diagnosis was made: Takayasu»s arteritis type IV affecting the aorta and its branches, moderate activity. Occlusion of the celiac trunk. Aneurisms of the branches of the superior mesenteric artery. Critical stenosis of the left renal artery. Thrombosis of the aorto-renal prosthesis. Hypoplasia of the left kidney. Prednisolone 50 mg a day, metoprolol 50 mg a day, valsartan 160 mg a day, acetylsalicylic acid 100 mg a day were prescribed.

Conclusion. The presented clinical observation shows the importance of comprehensive examination of young patients complaining of elevated AP for many years. Due to untimely diagnosis and absence of pathogenetic therapy, the patient suffered negative consequences of surgical treatment.
