Renal arteriovenous fistula complicated with malignant hypertension: a case report

We reported a case of RAVF presented as malignant hypertension, which was detected by contrast-enhanced ultrasonography and successfully managed by interventional embolization. A 35-year-old male was presented with a headache and blurred vision. His blood pressure was up to 220/110 mmHg, with significantly elevated serum creatinine and proteinuria. Hypertensive target organ impairments were noted. A RAVF was detected by contrast-enhanced renal ultrasonography. He underwent renal artery angiography and renal arteriovenous fistula embolization. RAAS activation was also evaluated by separate renal vein sampling. The patient's blood pressure and target-organ damage improved after RAVF embolization and blood pressure control. This is a rare case of renal arteriovenous fistula with malignant hypertension. Contrast-enhanced ultrasonography can be useful for diagnosis.
