Time-Staged Gamma Knife Stereotactic Radiosurgery for Large Cerebral Arteriovenous Malformations: A Preliminary Report
OBJECTIVE We retrospectively analyzed our experience with time-staged gamma knife stereotactic radiosurgery (GKS) in treating large arteriovenous malformation(AVM)s;≥ 10 cm3). METHODS Forty-five patients who underwent time-staged GKS (2-stage, n = 37;3-stage,n = 8) between March 1998 and December 2011 were included. The mean volume treated was 20.42±6.29 cm3 (range, 10.20-38.50 cm3). Oblitera...
متن کاملStereotactic radiosurgery of intracranial arteriovenous malformations.
Stereotactic radiosurgery for intracranial arteriovenous malformations (AVMs) has been performed since the 1970s. When an AVM is treated with radiosurgery, radiation injury to the vascular endothelium induces the proliferation of smooth muscle cells and the elaboration of extracellular collagen, which leads to progressive stenosis and obliteration of the AVM nidus. Obliteration after AVM radios...
متن کاملRadiosurgery for patients with unruptured intracranial arteriovenous malformations.
OBJECT The appropriate management of unruptured intracranial arteriovenous malformations (AVMs) remains controversial. In the present study, the authors evaluate the radiographic and clinical outcomes of radiosurgery for a large cohort of patients with unruptured AVMs. METHODS From a prospective database of 1204 cases of AVMs involving patients treated with radiosurgery at their institution, ...
متن کاملStaged embolization with staged gamma knife radiosurgery to treat a large AVM.
Treatment of arteriovenous malformations (AVMs) is complicated because of many factors including increasing size, eloquent location, and risk of unacceptable neurological deficits. Each of the treatment modalities, microsurgery, embolization, and stereotactic radiosurgery (SRS), has its pros and cons. Surgery and embolization are limited by location, size, and afferent and efferent vessel anato...
متن کاملStereotaxic angiography in gamma knife radiosurgery of intracranial arteriovenous malformations.
Gamma knife radiosurgery is an effective alternative to embolization or microsurgical removal of small arteriovenous malformations, particularly in eloquent areas of brain tissue. Stereotaxic angiography is a useful diagnostic and targeting adjunct to gamma knife radiosurgery, and the authors present their experience (1,100 patients) with methods and technique, and show how the nidus of the art...
