Headway duo microcatheter combined with Onyx glue in preoperative embolization of meningiomas

Abstract

Objective To evaluate the clinical value of Headway duo microcatheter combined with Onyx glue in embolization of meningiomas. Methods A retrospective analysis on clinical data of 12 patients with meningiomas, admitted to our hospital from December 2015 to March 2017, was performed. According to the blood supply typing of Manelfe meningiomas, 5 were type I, 3 were type II, 2 were type III, and 2 were type IV. The degrees of embolization were compared by DSA tumor staining before and after embolization; and complications of embolization were recorded. Results Cerebral angiography after embolization demonstrated complete embolization in 5 patients, subtotal embolization in 5, partial embolization in 2, and small amount of embolization in 0. Only 2 had head and face pain in the process of embolization, and these syndromes disappeared once the operation stopped. The mean average blood loss in the surgery was 685 mL and the mean surgical time was 4.45 h. Conclusion Headway duo microcatheter combined with Onyx glue in the embolization of intracranial meningiomas can play a good role in blocking blood flow, and results suggest that this method is safe and effective, worth of clinical promotion.
