Percutaneous endoscopic contralateral interlaminar lumbar foraminotomy (PECILF) for lumbar degenerative spinal stenosis is an established procedure. Better preservation of contralateral facet joint compared with that of the approach side has been shown with uniportal bilateral decompression. The aim of this retrospective case series was to analyze the early clinical and radiologic outcomes of stand-alone contralateral foraminotomy and lateral recess decompression using PECILF. ⋯ Facet-preserving contralateral foraminotomy and lateral recess decompression with PECILF is effective for treatment of lateral recess and foraminal stenosis. Thorough decompression with acceptable early clinical outcomes and minimal perioperative morbidity can be obtained with the contralateral endoscopic approach.

Motor cortex stimulation (MCS) was introduced in the early 1990s by Tsubokawa and his group for patients diagnosed with drug-resistant, central neuropathic pain. Inconsistencies concerning the details of this therapy and its outcomes and poor methodology of most clinical essays divide the neuromodulation society worldwide into "believers" and "nonbelievers." A European expert meeting was organized in Brussels, Belgium by the Benelux Neuromodulation Society in order to develop uniform MCS protocols in the preoperative, intraoperative, and postoperative courses. ⋯ Substantial commonalities but also important methodologic divergencies emerged from the discussion of MCS experts from 7 European Centers. From this meeting and questionnaire, all participants concluded that there is a need for more homogenous standardized protocols for MCS regarding patient selection, implantation procedure, stimulation parameters, and follow-up-course.

PHACE syndrome (Posterior fossa malformations, large cervicofacial infantile Hemangiomas, Arterial anomalies, aortic coarctation and Cardiac abnormalities, and Eye abnormalities) is a neurocutaneous disorder including posterior fossa malformations, hemangiomas, arterial lesions, cardiac defects, and eye abnormalities. PHACE arteriopathies may be progressive and recently have been categorized based on the risk of acute ischemic stroke, increasing attention to the potentially devastating consequences of cerebrovascular complications in this syndrome. In contrast, the natural history of arteriopathy in PHACE syndrome remains poorly understood. At the moment, there are no established surgical guidelines for high-risk vasculopathies, including quasi-moyamoya, in this syndrome. ⋯ Although the natural history of arteriopathy in PHACE syndrome is poorly understood, patients with high-risk vasculopathies, such as quasi-moyamoya disease, may benefit of revascularization by using encephaloduroarteriosynangiosis and encephalomyosynangiosis.

Case Reports Multicenter Study
Initial Clinical Experience with AView-A Clinical Computational Platform for Intracranial Aneurysm Morphology, Hemodynamics, and Treatment Management.
The management of intracranial aneurysm (IA) is challenging. Clinicians often rely on varied and intuitively disparate ways of evaluating rupture risk that may only partially take into account complex hemodynamic and morphologic factors. We developed a prototype of a clinically oriented, streamlined, computational platform, AView, for rapid assessment of hemodynamics and morphometrics in clinical settings. To show the potential clinical utility of AView, we report our initial multicenter experience highlighting the possible advantages of morphologic and hemodynamic analysis of IAs. ⋯ AView has the potential to confirm decisions to treat IAs, suggest which among multiple aneurysms to treat, and guide treatment decisions. Furthermore, the flow visualization it affords can inform aneurysm treatment planning and potentially avoid poor outcomes.

Occasionally, a favorable clinical disease-specific outcome does not reflect into improved generic health-related quality of life (HRQoL) in patients with idiopathic normal-pressure hydrocephalus (iNPH) at 1 year after the installation of a cerebrospinal fluid shunt. Our aim was to identify factors causing this discrepancy. ⋯ Frail patients suffering from certain pre-existing comorbidities may not experience improvement in generic HRQoL despite of a favorable clinical disease-specific response. Acknowledging the comorbidity burden of the patient may help clinicians and the patients to understand the conflict between patient-reported and clinical outcomes.
