“…At this stage, smooth muscle alpha-actin (aSMA) levels in vascular smooth muscle cells (VSMC) are low and incomplete, and the elastin coverage rate of the elastic protein layer (IEL) in AVM was also decreased, which are associated with the Notch2 mutation. 9 Most CRAVM patients remain asymptomatic until they are approximately 35 years old, 10 and most cases occur in older people, which might be relevant to the vascular walls that become fragile.…”

Renal arteriovenous malformations (AVMs) are infrequent vascular morphological anomalies. About 20% of AVMs are congenital renal AVMs (CRAVMs). A 53-year-old female patient presented with a 5-day history of gross hematuria and right flank pain. The patient underwent the selective renal arteriography and embolization under local anesthesia. Renal computed tomography angiography (CTA) and digital subtraction angiography (DSA) results showed bleeding of the right renal arteriovenous malformation, both nidus and aneurysm, which indicated that the patient had both cirsoid and cavernosal types of CRAVM. Endovascular management was chosen to treat the patient. The patient was cured and discharged, then followed-up for 3 months. These results show that early identification using radiologic tests is important for diagnosis and treatment of CRAVM.

“…При этом тяжесть гематурии не коррелирует с размерами мальформации, и даже аномалия малых размеров может привести к развитию жизнеугрожающего состо-яния. Поэтому гематурия, увеличение размера свища, резистентная к терапии гипертония и сердечная недостаточность являются показаниями к хирургическому лечению АВМ [12].…”

This article describes the causes of vascular abnormality of the upper urinary tract, arteriovenous malformation of the kidneys, its variants, possible clinical manifestations, methods of diagnosis of this condition, as well as ways to eliminate hemorrhagic complications caused by this pathology. The main method of correction of arteriovenous malformation is superselective embolization of vessels of the malformation zone. This clinical example presents a rare case of surgery in which embolization was unacceptable due to technical difficulties associated with the complexity of vascular angioarchitectonics, with the impossibility of superselective entry into varix through the arterial channel. In this regard, endovascular surgeons and urologists had to use a combined approach – percutaneous varix puncture with the introduction of a spiral and an embolizing substance through a puncture needle under the control of selective angiography of the branches of the renal artery.
