目的研究血管内栓塞治疗脑动静脉畸形(cAVM)的临床疗效。方法在数字减影全脑血管造影监视下,经股动脉插管,采用微导管技术,α-氰基丙烯酸正丁酯(NBCA)栓塞剂对23例cAVM患者行血管内栓塞,一次栓塞6例,分次栓塞17例,共45人次。11例栓塞后行γ-刀治疗。结果23例患者,血管畸形团完全栓塞达6例,>95%4例,70%～95%9例,70%以下4例,术后出现头晕、头痛3例。随访23例,4例仍有癫痫发作,余临床症状均明显改善。结论血管内栓塞治疗cAVM安全有效,单纯栓塞可治愈部分cAVM,血管内栓塞结合γ-刀放射治疗,可提高其治愈率。
Objective To study the clinical effect of endovascular embolization on cerebral arteriovenous malformation (cAVM). Methods Twenty-three patients with cAVM underwent coronary angiography with digital subtraction whole-brain angiography. Six patients underwent thromboembolism via femoral artery catheterization and micro-catheter technique. NBCA embolic agent , 17 cases of embolism, a total of 45 people. Eleven patients underwent embolization γ-knife treatment. Results Of the 23 patients, 6 cases were completely embolized with vascular malformations, 95% were in 4 cases, 70% ~ 95% in 9 cases and 70% in 4 cases. There were 3 cases of dizziness and headache after operation. Follow-up of 23 cases, 4 cases still have seizures, more than the clinical symptoms were significantly improved. Conclusions Endovascular embolization is safe and effective in treating cAVM. Simple embolization can cure some cAVMs. Intravascular embolization combined with γ-knife radiotherapy can improve the cure rate.
