Dò động tĩnh mạch màng cứng não (DĐTMMCN) là dò từ động mạch vào tĩnh mạch màng cứng và hoặc xoang tĩnh mạch màng cứng tại não. Nguy cơ đột quỵ xuất huyết não hàng năm lên đến 10,5% khi có dội ngược vào tĩnh mạch vỏ não. Mục đích nghiên cứu của chúng tôi nhằm đánh giá hiệu quả và độ an toàn của kỹ thuật can thiệp nội mạch trong điều trị DĐTMMCN. | KẾT QUẢ BƯỚC ĐẦU CAN THIỆP NGHIÊN CỨU KHOA HỌC NỘI MẠCH ĐIỀU TRỊ DÒ ĐỘNG TĨNH MẠCH MÀNG CỨNG NÃO SCIENTIFIC RESEARCH TẠI BỆNH VIỆN CHỢ RẪY Initial results of endovascular embolization for treatment of intracranial dural arteriovenous fistulas at Cho Ray Hospital Lê Văn Phước Nguyễn Huỳnh Nhật Tuấn Lê Văn Khoa SUMMARY Objectives Brain dural arteriovenous fistulas are connections of the branches of dural arteries to dural veins or a venous sinus at brain. Annually the risk of cerebral hemorrhagic stroke is increasing the risk of intracranial hemorrhage due to retrograde cortical venous drainage. Currently treatment options include surgery gamma knife and endovascular intervention but most clinicians consider endovascular treatment to be the method of first choice. The purpose of this study was to assess the efficacy and safety of endovascular intervention for the treatment of brain dural arteriovenous fistula. Subjets and methods All the patients treated by endovascular intervention for the treatment of brain dural arteriovenous fistula at Cho Ray hospital from June 2015 to January 2017. The techniques for treatment include transarterial and or transvenous approach microcatheter was inserted and reached the fistula point embolization was performed with material agent such as coils n-BCA PVA . The efficacy and safety were evaluated by variants complete partial embolization procedural success rate clinical improvement procedural complications. Results 52 patients treated by endovascular intervention. The technical success rates with complete obliteration by transvenous approach are 30 39 patients technical success rates with complete obliteration by transarterial approach are 4 6 patients complete obliteration by combined transarterial and transvenous approach 6 7 patients mortality rate 1 52 hemorrhagic stroke 3 52 vomiting and headache 4 52 . Conclusions Endovascular intervention of brain dural arteriovenous fistulas is a safe and .
