Abstract: Introduction: renal arteriovenous malformation (AVM) is a pathological communication between renal arteries and veins, both acquired and congenital. Congenital AVMs of kidneys, on average, remain asymptomatic for up to 30-40 years, occurring mainly in women, may manifest with hematuria and pain. Nephrectomy is known to be historical method of treating AVM of the kidney, however, with the development of angiographic instrumentation, endovascular methods of treatment began to be introduced into practice more often. Case report: a 30-year-old female patient with ongoing recurrent bleeding from the urogenital tract. Performed preoperative examination: laboratory tests, cystoscopy, ultrasound, multispiral computed tomography. Patient underwent angiography followed by embolization of kidney AVM with Squid. Results: intraoperatively, it was noted that AVM embolization is partial. During the first day of the observation period, the presence of postembolization syndrome in the form of hyperthermia, pain and dysuric syndromes, a phenomenon of systemic reaction according to laboratory tests were noted. After 1,5 months, patient was hospitalized for second stage of embolizaion, but during angiography it appeared, that AVM is totally embolized. Conclusions: renal artery embolization in patients with renal arteriovenous malformations is a minimally invasive, effective method of treatment. 1. The process of selective embolization is controlled and can be used as an independent method of treatment. 2. Due to selective catheterization of arteries and the infusion of agent directly into the affected area, segmental infarction occurs, as a result of which there is minimal destruction of the healthy part of the kidney parenchyma, the function of the kidney will not suffer.
