BACKGROUND AND PURPOSE: Hypertensive basal ganglia hemorrhage (HBGH) accounts for 35%-44% of cases of hypertensive intracranial hemorrhage (ICH), which is one of the most devastating forms of cerebrovascular disease. In this study, intracerebral hematoma was evacuated with a burr hole craniectomy. The relationships of residue hematoma volume to brain edema, ...

BACKGROUND: It is unclear whether the benefit of adding whole-brain radiation therapy (WBRT) to stereotactic radiosurgery (SRS) for the control of brain-tumours outweighs the potential neurocognitive risks. We proposed that the learning and memory functions of patients who undergo SRS plus WBRT are worse than those of patients who undergo ...

OBJECTIVE: Arteriovenous malformations (AVMs) treated by radiosurgery with complete obliteration of the nidus but a persisting early draining vein on follow-up angiography can be termed subtotally obliterated. However, these are persistent circulating AVMs. The significance of these lesions, their hemorrhage rate, and their management are analyzed. METHODS: In a series ...

OBJECTIVE: Gamma knife radiosurgery (GKRS) is occasionally a useful tool for maintaining good brain status in patients with brain metastases (METs). Conversely, we recently experienced patients with delayed cyst formation (DCF) several years after GKRS, a complication not previously reported. Herein we assessed the frequency and characteristics of DCF after ...

OBJECTIVE: Intracerebral hemorrhage (ICH) has a high mortality rate and leaves most survivors disabled. The dismal outcome is mostly due to the mass effect of hematoma plus edema. Major clinical trials show no benefit from surgical or medical treatment. Decompressive craniectomy has, however, proven beneficial for large ischemic brain infarction ...

PURPOSE: Primarily, gamma knife centers are predominant in publishing results on arteriovenous malformations (AVM) treatments including reports on risk profile. However, many patients are treated using a linear accelerator-most of these at smaller centers. Because this setting is different from a large gamma knife center, the risk profile at Linac ...

PURPOSE: Pulmonary arteriovenous malformation (PAVM) embolization has traditionally been performed as an inpatient procedure, often with sequential procedures to treat multiple lesions. This approach is costly, inconveniences the patient, and may lead to noncompliance with embolotherapy. In the authors' hereditary hemorrhagic telangiectasia (HHT) center, all PAVM embolizations in teenagers and ...

The decision to adopt a conservative or surgical modality for a relatively small volume of spontaneous intracerebral hemorrhage (SICH) is difficult and often controversial, especially when consciousness is tolerable. The authors examined the results of stereotactic-guided evacuation of SICH for relatively small volumes with respect to functional outcome. This prospective ...

BACKGROUND: Although the ABC/2 formula has been widely used to estimate the volume of intracerebral hematoma (ICH), the formula tends to overestimate hematoma volume. The volume-related imprecision of the ABC/2 formula has not been documented quantitatively. PURPOSE: To investigate the volume-dependent overestimation of the ABC/2 formula by comparing it with ...

OBJECTIVE: Intraventricular extension of intracerebral hemorrhage (IVH) is an independent predictor of poor outcome. IVH volume may be important in outcome prediction and management; however, it is difficult to measure routinely. DESIGN AND PATIENTS: We reviewed the charts and computed tomographies of a cohort of consecutive patients with IVH. The ...
