INTRODUCTION: The multimodal approach to treatment of @entity2758 yields good results. However, small and deep @entity600 still pose a big problem for surgeons. Transvenous embolization was designed as an alternative for the cases when endovascular treatment is required and conventional transarterial embolization is not available. CASE STUDY: A 41-year-old @entity1 with @entity600 in the subcortical nuclei of the left hemisphere of the brain, which had previously become a source of massive @entity548 , was operated on using the transarterial and, for the first time in our clinic, transvenous approaches. Transarterial embolization of the thalamic node of @entity600 was performed as the first step. After 6 months, transvenous embolization of the hypothalamic node of @entity600 was performed as the second step. Successful operation was ensured by using a stable coaxial guiding catheter system with the maximum distal approach and intranidal positioning of a microcatheter with detachable distal portion upon temporary occlusion of afferent vessels of the @entity600 using a balloon catheter. The operation resulted in total @entity715 of the @entity600 . No perioperative complications were observed. Control examination in 6 months did not reveal recanalization of the @entity600 . CONCLUSION: The transvenous approach can be successfully used in endovascular treatment of small and deep @entity2758 with a single drainage vein, which are inaccessible to direct surgery. It can also be used when radiosurgery is associated with a high risk in cases where transarterial embolization is infeasible.
