Outcomes of gamma knife radiosurgery for trigeminal neuralgia after a minimum 3-year follow-up.

We conducted a retrospective study of the outcomes of 17 patients who underwent gamma knife radiosurgery (GKRS) for idiopathic trigeminal neuralgia (TN) with a minimum 3-year follow-up. The median interval from GKRS to pain improvement was 4 weeks (range, 1-16 weeks). At the last follow-up, a good treatment outcome was verified in 16 (94.

Fibrinogen and D-dimer analysis of chronic subdural hematomas and computed tomography findings: a prospective study.

Objective: We investigated the relationship between fibrinolytic factors and computed tomography (CT) findings in patients with chronic subdural hematomas (CSDHs).

Methods: Thirty-one patients with CSDHs were divided on the basis of CT findings into heterogeneous and homogeneous groups. A sample from the subdural hematoma was obtained at surgery to measure the concentrations of fibrinogen and D-dimer.

The retrogasserian zone versus dorsal root entry zone: comparison of two targeting techniques of gamma knife radiosurgery for trigeminal neuralgia.

Background: We performed a comparative study of the retrogasserian zone (RGZ) with the dorsal root entry zone (DREZ) target to determine effective gamma knife radiosurgery (GKRS) technique in patients with medically refractory trigeminal neuralgia (TN).

Methods: We retrospectively reviewed the records of 39 patients with refractory TN undergoing GKRS between April 2005 and October 2008. Until October 2007, DREZ was used as the primary target point.

Gamma knife radiosurgery for multiple brain metastases from lung cancer.

The aim of this study was to compare the effectiveness of gamma knife radiosurgery (GKS) for the treatment of multiple brain metastases from lung cancer with that of whole brain radiation therapy (WBRT). Patients with multiple (2-20) brain metastases were divided into two groups for initial brain tumor management: a GKS group (14 patients) and a WBRT group (19 patients). The patients were stratified by gender, age, initial Karnofsky performance status score, control of the primary site, known extracranial metastases, number of brain metastases, diameter of the maximal lesion, chemotherapy, and recursive partitioning analysis (RPA) Class.

Transcranial Doppler study of cerebral arteriovenous malformations after gamma knife radiosurgery.

The aim of this study was to evaluate the clinical value of the Transcranial Doppler (TCD) in follow-up examinations after gamma knife radiosurgery (GKS) for arteriovenous malformations (AVM). We performed TCD after GKS in 18 patients who had cerebral AVMs to evaluate the hemodynamic effects of the procedure. Ten patients underwent TCD within 12 months after GKS, and eight between 12 and 24 months.

Chronic subdural hematoma preceded by traumatic subdural hygroma.

Patients with traumatic subdural hygroma (SDG) are at an increased risk of developing chronic subdural hematoma (CSDH). However, the mechanism by which this occurs is still not fully understood. The purpose of this paper is to investigate the clinical characteristics and pathogenesis of CSDH, as well as the relationship between CSDH and SDG.
