Abstract:
To analysis the treatment effectiveness of maxillofacial arteriovenous malformation (AVM) by means of temporary balloon block and percutaneous puncture sclerotherapy. The treatment outcomes of 20 patients with AVM of maxillofacial deformity, aged (26.8±3.0) 18-36 years, from Dec 2012 to Dec 2019 were collected and retrospectively analyzed. All patients had been diagnosed AVM by digital substraction angiography (DSA). All the cases were treated by using balloons to temporary block responsible artery of the AVM in order to change the high-flow malformations into low-flow venous malformation. Then injection of polyethylene foam cinnamyl alcohol was conducted via percutaneous puncturing for hardening the vascular malformation. Comparing the symptoms and imaging changes before treatment with those 1-6 months after treatment according to Achauer curative effect evaluation standard. Totally 60% (12/20) of the cases were type Ⅱa AVM, and their treatments were effective. However, the treatment effects of type Ⅲb and type Ⅳ patients were relatively poor. The clinical effective rate was 85% (17/20), and the clinical curative rate was 50% (10/20). No skin necrosis, organ damage and other serious complications were observed for the 20 patients. The AVM patients with a main supply artery treated by using a balloon artery temporary block to make high flow malformations into low-flow and followed by percutaneous puncture sclerotherapy, could get good curative effect. It seemed that this approach was safe and effective.
