Data on large vessel strokes are important for resource allocation and infrastructure development. ⋯ This study estimates an LVO incidence of 24 per 100 000 person-years (95% CI 20 to 28). A current estimated annual thrombectomy rate of three procedures per 100 000 people indicates significant potential increase in the volume of endovascular procedures and the need to develop systems of care.

The annual cost of healthcare delivery in the USA now exceeds US$3 trillion. Fee for service methodology is often implicated as a cause of this exceedingly high figure. The Affordable Care Act created the Center for Medicare and Medicaid Innovation (CMMI) to pilot test value based alternative payments for reimbursing physician services. ⋯ In October 2016, the Centers for Medicare and Medicaid Services (CMS) released a final rule for MACRA implementation, providing greater clarity regarding 2017 requirements. The final rule provides a range of options for easing MIPS reporting requirements in the first performance year. Nonetheless, taking the newly offered 'minimum possible' approach toward meeting the requirements will still have negative consequences for providers.

Flow diversion represents a novel but definitive treatment for recurrent and difficult-to-coil aneurysms of the anterior communicating artery (ACoA) region, of which reports are limited. ⋯ The PED can be used safely and effectively in the treatment of aneurysms of the ACoA region. This represents a good alternative treatment option to microsurgical clipping and endovascular coiling.

Comparative Study
Endovascular thrombectomy for M2 occlusions: comparison between forced arterial suction thrombectomy and stent retriever thrombectomy.
To date there has been no direct comparison of two frequently used endovascular thrombectomy (EVT) methods (forced arterial suction thrombectomy (FAST) and stent retriever thrombectomy) in M2 occlusions. We review our experiences with EVT performed using FAST and stent retriever thrombectomy in such cases. ⋯ Stent retriever thrombectomy may provide faster reperfusion than FAST, while the FAST technique might be associated with lower distal embolization and a higher reperfusion rate for the first thrombectomy attempt, but without any significant difference in clinical outcome. When choosing the EVT method for M2 occlusions, consideration of the location of the occlusion and tortuosity between M1 and M2 might be helpful to achieve a better angiographic outcome.

Studying the imaging and histopathologic characteristics of thrombi in ischemic stroke could provide insights into stroke etiology and ideal treatment strategies. We conducted a systematic review of imaging and histologic characteristics of thrombi in acute ischemic stroke. ⋯ The hyperdense artery sign is associated with RBC-rich thrombi and improved recanalization rates. However, there was no association between the histopathological characteristics of thrombi and stroke etiology and angiographic outcomes.
