Abstract

The purpose of this study was to analyze the effect of single-fraction stereotactic radiosurgery (SRS) for the treatment of 15 cases of cerebral arteriovenous malformations (AVMs). Between 2002 and 2009, of the 25 patients who had SRS for the treatment of cerebral AVM, 15 patients (6 men, 9 women) taken a digital subtraction angiography (DSA) over 12 months after SRS were included. We retrospectively evaluated the size, location, hemorrhage of nidus, angiographic changes on follow-up on the MR angiography and DSA, and clinical complications during follow-up periods. At a median follow-up of 24 months (range 12-89), complete obliteration of nidus was observed in all patients (100%) while residual draining veins was observed in 3 patients (20%). There was no clinical complication during the follow-up period except seizure in 1 patient. The mean nidus volume was 4.7cc (0.5~11.7 cc, SD 3.7 cc). The locations of nidus were in cerebral hemisphere in 11 patients, cerebellum in 2 patients, basal ganglia in 1 patient, and pons in 1 patient respectively. 9 cases were hemorrhagic, and 6 cases were non-hemorrhagic AVMs. The SRS with LINAC is a safe and effective treatment for cerebral AVMs when the follow up period is over 4 years. However, it is recommended to continue to follow up until the draining vein on arterial phase of follow up DSA disappears completely.

선형가속기를 이용하여 single-fraction stereotactic radiosurgery (SRS)를 시행하였던 뇌동맥 기형 치료 환자 25예 중 13예의 임상결과와 혈관조영술 소견에 대해 알아보고자 하였다. 2002년부터 2009년까지 뇌동정맥 기형으로 SRS를 시행하였던 25명 중 추적 혈관조영술이 시행된 기간이 12개월 이상인 환자 15명(남자 6명, 여자 9명)을 대상으로 하였으며 후향적으로 MRI와 혈관조영술에서 동정맥기형 핵의 크기와, 위치, 파열유무, 추적기간 동안의 합병증 유무, 혈관조영술에서의 변화를 분석하였다. 평균 30개월(12~89개월) 동안 추적 혈관조영술이 시행되었던 15명의 환자 (평균나이 33세, 14~56세) 중 모든 환자에서(100%) 동정맥기형이 완전 소실되었고 3명(20%)에서 유출정맥만이 동맥기 촬영에서 확인되었다. 추적기간 중 1명에서 경련이 있었으며 출혈이나 뇌부종에 의한 임상증상이 있었던 환자는 없었다. 동정맥기형 핵의 부피는 평균 4.3 cc (SD 3.7 cc, 범위 0.69~11.7 cc)였으며 방사선 조사 선량은 평균 17 Gy (12~20 Gy)였다. 동정맥기형의 위치는 대엽이 11예, 기저핵이 1예, 뇌교가 1예, 소뇌가 2예였다. 9예는 파열, 나머지 6예는 비 파열 예였다. 선형가속기를 이용한 뇌동정맥기형 방사선 치료의 성적은 추적기간을 4년 이상으로 할 때 높은 완치율을 보이며 동맥기에 유출정맥이 남아 있을 경우 유출정맥이 완전히 소멸될 때까지 추적 관찰이 요구된다.
