作者报告了三年内应用异丁基-2-氰丙烯(Isobuty1-2-Cyanoacrylate,IBCA)治疗脑动静脉畸形(AVM)和瘘的经验。 IBCA为一液态组织粘合剂,一经与离子性溶液如血液接触立即聚合,其粘稠度低,故可用带标定漏口的胶囊微导管准确投放,可混以微粒钽粉使其不透X线。若加入小量iophendylate,尚可略延长其聚合时间。近期组织病理学材料显示其可产生动脉内持久性闭塞,伴随的纤维性反应不大于丝线缝合所见者。本组选择40例颅内AVM与6例颈动脉海绵窦
The authors report the experience of using Isobuty1-2-Cyanoacrylate (IBCA) in the treatment of cerebral arteriovenous malformations (AVMs) and fistulas within three years. IBCA is a liquid tissue adhesive, once in contact with ionic solution such as blood immediately polymerization, its low viscosity, it can be used with a calibrated capsule microcatheter accurately leak can be mixed with particles of tantalum powder to make it through X line. If you add a small amount of iophendylate, can slightly extend the polymerization time. Recent histopathological materials have shown that they can produce persistent intra-arterial occlusion with no more fibrotic response than seen with silk suture. This group choose 40 cases of intracranial AVM and 6 cases of carotid cavernous sinus
