A study was undertaken to estimate the fraction of intracranial aneurysms that might be amenable to treatment with the pipeline embolization device (PED), a current flow diverter device, and to determine the types of aneurysms that are probably not amenable to treatment with this device. ⋯ On the basis of anatomical configuration, nearly half of the aneurysms in this study were likely to be amenable to treatment with the PED.

Monitoring various physiological parameters and their derangements provides a valuable tool for management of severely brain injured patients. The various parameters and their monitoring tools include but are not all inclusive are cerebral blood flow and oxygen monitoring, jugular bulb oximetry, intracerebral microdialysis and continuous electroencephalography. It needs to be seen how these devices are applied to improve patient outcomes.

The Independent Payment Advisory Board (IPAB) is a powerful component of the Affordable Care Act, with the authority to issue recommendations to reduce the growth in Medicare spending and to provide recommendations to Congress for fast-track implementation. The IPAB works by recommending policies to Congress to help Medicare provide better care at a lower cost, including ideas on coordinating care, getting rid of waste in the system, providing incentives for best practices and prioritizing primary care. Congress then has the power to accept or reject these recommendations. ⋯ The applicable percentage for maximum savings appears to be 0.5% for 2015, 1% for 2016, 1.25% for 2017 and 1.5% for 2018 and later. The IPAB Medicare proposal process involves mandatory recommendations and advisory recommendations with multiple reporting requirements. We believe neurointerventionalists, as highly specialized physicians reliant on expensive technology, should be aware of the IPAB and its impact on the practice of medicine.

The presence of active contrast extravasation during CT angiography, the spot sign, is a potent predictor of in-hospital mortality in patients with primary intracerebral hemorrhage (ICH). However, its predictive value in patients with ICH due to a vascular abnormality, secondary ICH (SICH), is unknown. The aim of this study was to determine the clinical and radiological predictors of a spot sign and in-hospital mortality in patients with SICH. ⋯ The spot sign identifies patients with SICH at increased risk of in-hospital mortality. However, the admission Glasgow Coma Scale was the only independent predictor of in-hospital mortality in this cohort of patients with SICH.

The endovascular treatment of acute ischemic stroke has been revolutionized in the past years by the introduction of new devices for mechanical thrombectomy. Several tools were already available in 2008. The majority allowed the recanalization of acutely occluded intracranial arteries with acceptable levels of safety and efficacy, and with occasional failures. ⋯ The Solitaire stent was initially developed for the endovascular treatment of wide necked intracranial aneurysms but has been demonstrated to be safe and efficacious for intracranial thrombectomy. This was the first successful human clinical use of a Solitaire stent for this purpose and the ignition spark for the development of a whole generation of new devices, now called stent retrievers.
