Preoperative embolization of the vessels, supplying primary brain tumors

Abstract

Introduction. The problem of operations performing at brain tumors of difficult topographic localization and intensive blood supply requires search of new methods for it’s solving.Methods. Indications for tumor devascularization are: hypervascular vasculature available for embolization. After determination of target-vessels embolization was performed.Results. In 92% observations effective devascularization of tumor node was achieved. In 17 (65%) patients embolization was considered as total, in 7 (27%) — significant part of tumor vasculature was occluded, in 2 (8%) — embolization was acknowledged as sufficient.Conclusions. This method allows to decrease the blood loss during surgical removing of extra-intracerebral tumors with intensive blood supply. This gives an opportunity to perform more radical and less traumatic surgery.
