Factors Affecting Distal Hyperintense Vessel Sign, a Postulated Marker for Intracranial Collateral Circulation (P4.256)
Conclusions:We note consistencies between prior studies and our study showing that younger patients without hypertension have better collaterals. We also found an association of diabetes with less DHVS whereas prior studies have yielded an inconsistent association. While a correlation between stroke severity and stroke volume could not be confirmed, low power and wide stroke-to-MRI gap (range 1–8 d) were important limitations here. Further study correcting these shortcomings is warranted. In conclusion, our findings support the origins of DHVS from collateral circulation and are affected by traditional cerebrovascula...

Vasa Vasorum Enhancement on Computerized Tomographic Angiography Correlates with Symptomatic Patients with 50% to 70% Carotid Artery Stenosis (P4.259)
Conclusions:In patients with 50% to 70% ICA stenosis, VV enhancement recognized on computed tomographic angiography is strongly associated with acute neurological symptoms compared with calcified and nonenhancing-noncalcified arterial plaques. This finding may aid in the identification of patients at increased risk for ischemic stroke within populations with the same degree of stenosis.Disclosure: Dr. Pizzolato Umeton has nothing to disclose.

Association between Increased Brachial-ankle Pulse Wave Velocity and Cerebral Perivascular Space (P4.260)
Conclusions:Increased baPWV was independently associated with severity of cerebral PVS, especially in younger individuals. This finding provided further evidences of the relationship between arterial stiffness and cerebral small vessel disease.Study Supported by:National Natural Science Foundation of China (grant number: 81173663), and National Key Technology R&D Program in the 12th five-year Plan of China (grant number: 2012BAJ18B04-3, 2015AA020506)Disclosure: Dr. Zhai has nothing to disclose.

Quick-brain MRI as first imaging modality to diagnose pediatric stroke (P4.261)
Conclusions:QB was the most common first study, was sensitive for acute stroke, and resulted in rapid diagnosis, with no missed findings. This small study suggests that QB may be considered as a first study in children with symptoms of acute stroke.Disclosure: Dr. Christy has nothing to disclose. Dr. Wilson has nothing to disclose.

Early Clinical Improvement in Central Retinal Artery Occlusion is Associated with Central Retinal Artery Recanalization (P4.262)
Conclusions:In our case series, no patient without early recanalization of the CRA had ECI.

Symptomatic Intracranial Hemorrhage after IV tPA for Acute Ischemic Stroke Patients with Relative Contraindications to Treatment (P4.267)
Conclusions:12 AIS patients with Class 3 exclusion criteria were treated with IV tPA. Our eight cases of IV tPA in pICH patients adds substantially to the existing literature. In this study, 25% of patients with pICH developed symptomatic ICH after IV tPA. Although the low number of eligible patients limits interpretation of our findings, continued caution when considering IV tPA for AIS patients with pICH may be warranted. More data is needed to clarify the impact these relative contraindications have on the treatment of AIS.Disclosure: Dr. Smith has nothing to disclose. Dr. Alkuwaiti has nothing to disclose.
