Patients were evaluated and treated by the same team and followed with the same protocol. The primary endpoint was the efficacy of EVT on the cure of low-grade bAVMs. The second endpoint was the safety of EVT for the treatment of low-grade bAVMs, including procedural complications and long-term clinical outcomes.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n A total of 109 patients were enrolled and represented in the study population. The mean patient age was 31.6 \u00b1 14.8 years. Forty-eight AVMs (44%) were Spetzler-Martin grade I and 61 (56%) were grade II. Of 99 patients who completed their EVT sessions, complete exclusion was achieved in 89 patients (89.9%). Overall, complete exclusion was achieved in 59.6% of patients after a single EVT session. At the 6-month follow-up, 106 patients (97.2%) had a favorable outcome. Four patients (4.6%) experienced transient neurological deficits, and 1 patient (0.9%) had a permanent neurological deficit.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n EVT can be offered as the first choice of treatment for select patients with low-grade bAVMs, with a high cure rate and low morbidity.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2022.4.focus22122","type":"journal-article","created":{"date-parts":[[2022,7,1]],"date-time":"2022-07-01T07:36:45Z","timestamp":1656661005000},"page":"E8","source":"Crossref","is-referenced-by-count":18,"title":["Endovascular treatment as the first-line approach for cure of low-grade brain arteriovenous malformation"],"prefix":"10.3171","volume":"53","author":[{"given":"Seyed Ali Shariat","family":"Razavi","sequence":"first","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Hossein","family":"Mirbolouk","sequence":"additional","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reza","family":"Gorji","sequence":"additional","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feizollah","family":"Ebrahimnia","sequence":"additional","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Payam","family":"Sasannejad","sequence":"additional","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samira","family":"Zabihyan","sequence":"additional","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farid Qoorchi Moheb","family":"Seraj","sequence":"additional","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hamid","family":"Etemadrezaie","sequence":"additional","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahla","family":"Esmaeilzadeh","sequence":"additional","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rapha\u00ebl","family":"Blanc","sequence":"additional","affiliation":[{"name":"Department of Interventional Neuroradiology, Rothschild Foundation Hospital, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michel","family":"Piotin","sequence":"additional","affiliation":[{"name":"Department of Interventional Neuroradiology, Rothschild Foundation Hospital, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Humain","family":"Baharvahdat","sequence":"additional","affiliation":[{"name":"Section of Neurovascular Intervention, Neurosurgical Department, Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran; and"},{"name":"Department of Interventional Neuroradiology, Rothschild Foundation Hospital, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"9917","key":"b1","series-title":"Lancet","doi-asserted-by":"publisher","first-page":"614","DOI":"10.1016\/S0140-6736(13)62302-8","article-title":"Medical management with or without interventional therapy for unruptured brain arteriovenous malformations (ARUBA): a multicentre, non-blinded, randomised trial","volume":"383","author":"Mohr JP","year":"2014","unstructured":"Mohr JP, Parides MK, Stapf C, Medical management with or without interventional therapy for unruptured brain arteriovenous malformations (ARUBA): a multicentre, non-blinded, randomised trial.
