Macrocalcification of intracranial vertebral artery may be related to in-stent restenosis: lessons learned from optical coherence tomography
Conclusions This study suggests a potential relationship between macrocalcifications and the risk of in-stent restenosis of the intracranial vertebral artery. These preliminary findings obtained from a limited sample should be verified by prospective large-scale studies.

E-060 Endovascular treatment for intracranial giant cell arteritis with angioplasty, stenting, and intra-arterial calcium channel blockers
ConclusionsEndovascular treatment, including PTA (with or without stenting) and CCB infusion, may be effective in medically-refractory GCA with intracranial arterial stenosis but complication rates are considerable. The efficacy of CCB monotherapy implicates vascular smooth muscle dysfunction in the pathogenesis of intracranial GCA.Calcium-channel blocker infusion as monotherapy for intracranial giant cell arteritis. Pre-treatment angiography (lateral right internal carotid artery projection) shows severe focal supraclinoid ICA stenosis (curved white arrow, 1A). Post-verapamil infusion (20mg, 15 min delay) angiogram (1B) s...

E-077 Laboratory analogs of challenging thromboemboli in acute ischemic stroke
Conclusion Thrombus analogs with mechanical characteristics similar to those of challenging clinical thrombi were successfully developed. The calcium apatite thrombus analog was found to be stiffer than the fibrin-rich thrombus analog. References .
