Stereotactic radiosurgery is a well-established treatment modality for vestibular schwannoma. Initial reports using single-stage radiosurgery have demonstrated excellent tumor control rates. Many patients now elect to undergo radiosurgery given the potential for tumor control while avoiding the morbidity associated with microsurgical resection. In attempt to improve hearing preservation rates o...

PURPOSE This European Organisation for Research and Treatment of Cancer phase III trial assesses whether adjuvant whole-brain radiotherapy (WBRT) increases the duration of functional independence after surgery or radiosurgery of brain metastases. PATIENTS AND METHODS Patients with one to three brain metastases of solid tumors (small-cell lung cancer excluded) with stable systemic disease or a...

The management of pituitary adenomas entails a multidisciplinary approach that involves neurosurgeons, endocrinologists, and radiation oncologists. Traditionally, the treatment included medical management, surgery (transsphenoidal microsurgical resection and transcranial approaches), and conventional fractionated radiotherapy. Stereotactic radiosurgery, through the various competing radiosurgic...

BACKGROUND We report the result obtained using Gamma knife stereotactic radiosurgery on the trigeminal ganglion (TG) in a patient with trigeminal neuralgia (TN) secondary to vertebrobasilar ectasia (VBE). CASE DESCRIPTION Retrospective review of medical records corresponding to one patient with VBE-related trigeminal pain treated with radiosurgery. Because of the impossibility of visualizatio...

Optimal management of cavernous sinus hemangiomas remains unclear. Total microsurgical removal of these neoplasms may be extremely difficult due to their rich vascularization. Three cases of cavernous sinus hemangioma treated with low-dose Gamma Knife radiosurgery are presented. Marginal dose varied from 10 to 13 Gy. Treatment planning and radiation dosimetry were done with a goal of conformal ...

Background: Radiosurgery is defined as the use of high-dose ionizing radiation for precise and total destruction of a chosen target, avoiding concomitant or delayed harm to adjacent tissues. The three types of radiations include gamma rays (GammaKnife) by Cobalt-60, X8 rays using linear accelerator (LINAC) system, and charged-particles generated from synchocyclotron. Recommendations: Based on c...

Ventricular tachycardia is a frequent cause of mortality after myocardial infarction. Current treatment includes the implantation of cardioverter defibrillators and adjunctive therapies, such as catheter ablation or cardiac surgery. In patients where standard treatment fails, preclinical data showed that radiosurgery ablation of the ectopic substrate might be a viable option. Authors present a ...

BACKGROUND Stereotactic radiosurgery is the principal alternative to microsurgical resection for acoustic neuromas (vestibular schwannomas). The goals of radiosurgery are the long-term prevention of tumor growth, maintenance of neurologic function, and prevention of new neurologic deficits. Although acceptable short-term outcomes have been reported, long-term outcomes have not been well documen...

Radiosurgery is a therapeutic technique to deliver high dose radiation to the target. It induces radiobiological responses of lesions while minimizing radiation effect to the surrounding area. Gamma knife is one of the representative devices for stereotactic radiosurgery, which is exclusively designed for treatment of cerebral disorders. Gamma knife was developed as the first radiosurgical devi...

 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, us...
