Acute Basilar Artery Occlusion with Underlying High-Grade Basilar Artery Stenosis: Multimodal Endovascular Therapy in a Series of Seven Patients
Conclusion Mechanical thrombectomy combined with acute stenting of the basilar artery is technically feasible and may be an effective therapeutic option in the rare case of an acutely occluded high-grade stenosis of the basilar artery in patients with an otherwise poor prognosis.

Temporal Changes in Periprocedural Events in the Carotid Revascularization Endarterectomy Versus Stenting Trial Clinical Sciences
Conclusions— The hypothesized temporal reduction of stroke+death events for carotid stenting–treated patients was not observed. Further adjustment for changes in patient characteristics between periods, including the addition of asymptomatic patients and a >50% decrease in proportion of octogenarians enrolled, resulted in practically identical rates. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT00004732.

Reversible cerebral vasoconstriction syndrome with reversible renal artery stenosis
A 41-year-old woman presented with thunderclap headaches, cortical blindness, generalized seizures, and severe hypertension. Brain imaging (figure) showed features of reversible cerebral vasoconstriction syndrome (RCVS) and posterior reversible encephalopathy syndrome.1 Her neurologic examination improved, but severe hypertension persisted. Abdomen CT angiography showed right renal artery narrowing with possible dissection, initially attributed to fibromuscular dysplasia (FMD). Renal angioplasty was considered; however, she was discharged on multiple antihypertensive agents. Her blood pressure normalized, and parenchymal l...

Endovascular Clot Retrieval Therapy: Implications for the Organization of Stroke Systems of Care in North America Understanding and Applying the Endovascular Trials
Endovascular acute ischemic stroke therapy is now proven by randomized controlled trials to produce large, clinically meaningful benefits. In response, stroke systems of care must change to increase timely and equitable access to this therapy. In this review, we provide a North American perspective on implications for stroke systems, focusing on the United States and Canada, accompanied by initial recommendations for changes. Most urgently, every community must create access to a hospital that can safely and quickly provide intravenous tissue-type plasminogen activator and immediately transfer appropriate patients onward t...

Acute Reperfusion Therapy and Stroke Care in Asia After Successful Endovascular Trials Understanding and Applying the Endovascular Trials
The current status of and prospects for acute stroke care in Asia in the situation where both intravenous thrombolysis and endovascular therapies have been recognized as established strategies for acute stroke are reviewed. Of 15 million people annually having stroke worldwide, 9 million are Asians. The burdens of both ischemic and hemorrhagic strokes are severe in Asia. The unique features of stroke in Asia include susceptibility to intracranial atherosclerosis, high prevalence of intracerebral hemorrhage, effects of dietary and lifestyle habits, and several disorders with genetic causes. These features affect acute strok...

Racial/Ethnic Variation in Carotid Artery Revascularization Utilization and Outcomes: Analysis From the National Cardiovascular Data Registry Clinical Sciences
Conclusion— During the study period, utilization of CAS and CEA was highest among non-Hispanic whites. There was a trend toward increased CAS utilization over time among non-Hispanic whites and other groups, and a trend toward increased CEA utilization among Hispanics and blacks. In-hospital major adverse cardiac and cerebrovascular events remained comparable between groups, whereas 30-day major adverse cardiac and cerebrovascular events were significantly higher in blacks.

Endovascular Treatment of Acute Middle Cerebral Artery Occlusion: Comparison of Percutaneous Transluminal Angioplasty and Mechanical Embolectomy (P4.298)
CONCLUSIONS: Data from this national multicenter registry showed that both PTA and ME represent safe and effective recanalization methods of acute MCAo. Bridging therapy was associated with better clinical outcome in the case of ME+IVT than PTA+IVT combination.

Recurrent right middle cerebral artery territory infarctions in a patient with JAK2 (V617F) point mutation positive polycythemia rubra vera (P2.258)
CONCLUSIONS: Hyperviscosity in polycythemia with hematocrit of more than 43[percnt] is known to cause ischemic events and it is evident in our case where our patient had recurrent ischemic strokes whenever the HCT is about 50[percnt] and the right MCA M1 segment though a mild stenosis, it becomes a critical factor for this patient as the patient had recurrent right MCA territory infarcts and hence in addition to regular phlebotomy to keep hematocrit less than 43[percnt], our patient might also need intervention in the form of cerebral angioplasty or stenting to treat even mild arterial stenosis.

Endovascular management and outcome of acute middle cerebral artery stroke in the setting of spontaneous carotid dissection (P1.012)
Conclusion: This study provides additional evidence that endovascular management of carotid artery dissection in acute middle cerebral artery is effective and safe to maintain distal revascularization. Revascularization can be achieved with a combination of stenting, large catheter mediated angioplasty and thrombectomy. Further studies are warranted to investigate the role of endovascular recanalization for this stroke subtypeDisclosure: Dr. Gulati has nothing to disclose. Dr. Aghaebrahim has nothing to disclose.
