Active smoking is a major risk factor for intracranial aneurysm rupture (IAR); however, little is known about the effects of passive smoking on IAR. In China, female passive smoking is widespread and severe. This study aimed to assess whether passive smoking is associated with increased risk of IAR among nonsmoking women. ⋯ Although active current smoking was strongly associated with aneurysm rupture in female patients, passive smoking was not an independent risk factor for aneurysm rupture in nonsmoking women.

Secondary intracranial hypotension is a clinical syndrome associated with reduction of cerebrospinal fluid volume and dural continuity violation. The main symptoms are orthostatic headache associated with nausea, vomiting, diplopia, dizziness, and tinnitus. The treatment is usually nonspecific. ⋯ Volumetric reduction of the epidural space may be considered as a valuable therapeutic option in case of intracranial hypotension that is unresponsive to medical treatments and spinal blood patch, as well as when an altered compliance of the dural sac is hypothesized.

Neurosurgical patients are aging as the general population is becoming older. ⋯ This study identifies factors that predict perioperative complications for elderly patients undergoing elective craniotomies, particularly congestive heart failure, smoking history, chronic steroid use, anesthesia time, and estimated blood loss. Age alone should not preclude elective craniotomy.

Surgical management of hemifacial spasm associated with chiari I malformation: analysis of 28 cases.
Hemifacial spasm (HFS) associated with Chiari I malformation (CIM) is rare. This study aimed to analyze the frequency of HFS associated with CIM in our department and further to investigate the clinical characteristics, treatment strategies, and outcomes of these cases. ⋯ The results suggest that MVD can still be an effective treatment for HFS when it coexists with CIM. Furthermore, posterior fossa crowdedness may be a common risk factor for the 2 diseases, and foramen magnum decompression should be considered as the primary procedure in patients with HFS and symptomatic CIM.

Video Telescope Operating Monitor (VITOM) 3D: preliminary experience in cranial surgery. Technical Case Report.
Optimal vision and ergonomics are important factors contributing to achievement of good results during neurosurgical interventions. The operating microscope and the endoscope have partially filled the gap between the need for good surgical vision and maintenance of a comfortable posture during surgery. Recently, a new technology called video-assisted telescope operating monitor or exoscope has been used in cranial surgery. The main drawback with previous prototypes was lack of stereopsis. We present the first case report of cranial surgery performed using the VITOM 3D, an exoscope conjugating 4K resolution view and three-dimensional technology, and discuss advantages and disadvantages compared with the operating microscope. ⋯ VITOM 3D is a video system that has overcome the lack of stereopsis, a major drawback of previous exoscope models. It has many advantages regarding ergonomics, versatility, and depth of field compared with the operating microscope, but the holder arm and the mechanism of repositioning, refocusing, and magnification need to be ameliorated. Surgeons should continue to use the technology they feel confident with, unless a distinct advantage with newer technologies can be demonstrated.
