abstract background: the gamma knife radiosurgery (gkr) is an established management option for cerebral ar-teriovenous malformations (avms). therapeutic benefits of radiosurgery for arteriovenous malformations are complete obliteration of nidus with minimal neurological deficit. methods: radiosurgery was performed between february 2003 and april 2010 at kamraniye day clinic, teh-ran, iran, usi...

BACKGROUND Stereotactic radiosurgery (SRS) is known to safely result in a high obliteration rate for small and medium sized arteriovenous malformations (AVM). OBJECTIVE To evaluate the long-term outcome of patients treated with SRS, with special emphasis given to obliteration and toxicity rates. METHODS We performed a review of 43 cerebral AVM patients, treated from 1998 to 2008 with a sing...

BACKGROUND AND PURPOSE The purpose of radiosurgery of bAVMs is complete angiographic obliteration of its nidus. We assessed the diagnostic accuracy of 1.5T T2-weighted MR imaging and TOF-MRA images for detecting nidus obliteration after radiosurgery. MATERIALS AND METHODS The pre- and postradiosurgery MR images and DSA images from 120 patients who were radiosurgically treated for a bAVM were ...

INTRODUCTION The purpose of this article is to present the results of microsurgical clipping or endovascular coil obliteration of unruptured intracranial aneurysms (UIA), in a single cerebrovascular center with regard to successful obliteration and periprocedural complications. METHODS Data concerning patients with UIA were recorded in the neurovascular database of the neurosurgical departmen...

BACKGROUND Stereotactic radiosurgery (SRS) has been performed on patients with cerebral arteriovenous malformations (AVMs) for over 40 years. OBJECTIVE To evaluate the impact of treatment period on obliteration, intracranial hemorrhage (ICH), and radiation-induced complications (RICs). METHODS Retrospective comparison of 381 AVM patients having SRS during a 20-year period (group 1, January ...

The long-term outcomes of gamma knife surgery (GKS) in patients with posterior fossa arteriovenous malformations (AVMs) were retrospectively analyzed in 82 patients followed up for more than 5 years to evaluate the efficacy and safety. The median AVM volume at GKS was 0.95 cm(3). The prescribed dose to the AVM margin was median 18 Gy with 1-18 isocenters. The actual complete AVM obliteration ra...
