|Title:||Embolization of vascular malformations in head and neck regions. A single center experience|
|Citation:||Interventional Neuroradiology. Vol.10, No.1 (2004), 37-46|
|Abstract:||The purpose of this study is to determine the effectiveness of embolization of each type of vascular malformation. Thirty three patients with a diagnosis of vascular malformations in head and neck regions who were treated by embolization at Siriraj Hospital, Thailand, between 1997-2002 were reviewed retrospectively. There were 19 arteriovenous malformations (AVMs), two arteriolar-capillary types, ten venous malformations, one veno-lymphatic malformation and one mixed capillary and venous types. The goal of treatment is to restore function and to prevent bleeding complications with particularly good cosmetic results. The technique and therapeutic agents depended on the types and flow characteristics of each malformation. Transarterial embolization with N-butyl cyanoacrylate were used in AVMs, unless no arterial route approach, then direct puncture was tried. This was carried out in five patients with AVMs. Polyvinyl alcohol was used in two capillary lesions. All venous malformations were treated by absolute alcohol injection, percutaneously. All had good outcome without serious complications. Two patients had further plastic surgery, one was AVM of eyelid and the other was facial venolymphatic malformation. Embolization is considered to be the primary treatment by eradication of those abnormal vessels directly at the target, whereas delayed plastic surgery may be needed later.|
