METHOD FOR TREATMENT OF HIGH-FLOW ARTERIO-SINUS FISTULAS OF BRAIN WITH ISOLATED SINUS Russian patent published in 2021 - IPC A61B17/00 

FIELD: medicine; neurosurgery.

SUBSTANCE: intravenous injection of the drug adenosine is performed and from the moment of development of bradycardia, transarterial injection of the arterio-sinus fistula into the main afferent is performed through a microcatheter of non-adhesive embolizate and simultaneous intra-arterial jet injection of saline solution is performed through a guide catheter of 200 ml until the heart rhythm is restored, maximally filling the small afferents of the arterio-sinus fistula with non-adhesive embolizate.

EFFECT: method makes it possible to increase efficiency of shutting off high-flow arterio-sinus fistulas with isolated sinus transarterial access from the blood circulation, reducing the consumed amount of non-adhesive embolizate, achieving preservation of the sinus lumen, reducing high intracranial venous hypertension and the risk of intracranial hemorrhage.
