Deep brain stimulation (DBS) is an effective but costly treatment for patients with advanced Parkinson disease (PD). This study examined the cost-effectiveness of DBS in relation to its improved effectiveness to help funding decision makers decide whether the treatment should be adopted. The incremental cost-effective ratio (ICER) per quality-adjusted life year has been benchmarked as being between US$50,000 and US$100,000 by US agencies, whereas it is less than €30,000 per quality-adjusted life year in Europe. ⋯ Cost-effectiveness of subthalamic nucleus DBS for treatment of advanced PD is greater during a 2-year period than 1 year only. These results can be used as a reference for the use of DBS for PD in a region with public health financing.

Metastatic disease of the craniovertebral junction (CVJ) can cause pain, cranial nerve deficits, occipitocervical instability, or brainstem/spinal cord compression if left untreated. Many patients with metastasis in this region have a high burden of systemic disease and short life expectancy, making them poor candidates for aggressive surgical resections and fusion procedures. Traditionally, symptom palliation and local disease control in these patients has been achieved through conventional radiation therapy. Stereotactic radiosurgery (SRS) has the advantage of precisely delivering radiation to a target in fewer fractions. To our knowledge, we report the results of the largest series of patients with CVJ metastasis treated with stereotactic radiosurgery. ⋯ In well-selected patients, SRS for metastatic lesions of the CVJ has a low risk for complications or treatment failure, while achieving a high rate of palliation of pain symptoms.

Recent evidence has suggested a potential beneficial effect of aspirin on the risk of aneurysm rupture. This benefit must be weighed against its potential adverse effects as an antiplatelet agent in the setting of acute aneurysmal subarachnoid hemorrhage (SAH). ⋯ In the present study, patients taking aspirin had a lower rate of hemorrhagic presentation. In addition, taking aspirin did not adversely impact presenting clinical grade or radiographic grade, vasospasm, and outcome in the setting of aneurysmal SAH.

To review our surgical experience in minimally invasive transcranial endoscope-assisted microsurgical treatment of intracranial aneurysms, using the supraorbital keyhole craniotomy. ⋯ The minimally invasive supraorbital keyhole approach allowed safe surgical treatment of intracranial aneurysms, including after subarachnoid hemorrhage. The markedly improved endoscopic visualization increased the assessment of clip placement with ideal control of surrounding vessels including perforators for identification of incorrect clip position.
