BACKGROUND Open surgery and the retrograde endovascular approach via the distal left common carotid artery (LCCA) have some limitations in LCCA ostial stenosis treatment. The 'no touch' technique used in the renal artery was modified for this situation. METHODS Fifteen selective LCCA stenosis patients were treated by the modified 'no touch' technique in(More)
PURPOSE To determine the prevalence of dynamic respiratory tortuosity (DRT) of the vertebral artery ostium (VAO) as well as to evaluate its correlation with in-stent restenosis (ISR) and stent fracture. METHODS From March 2012 to June 2015, 178 consecutive patients (mean age 65.2±5.8 years; 124 men) with symptoms of atherosclerotic vertebrobasilar(More)
We developed an "olive-tipped" technique for preventing the distal filter retrieval catheter from entrapment in the stent struts during retrieval procedures after stent deployment and which we used in 2 vertebral artery stenting cases. A new wire entry port was made in the catheter at the transition of larger and smaller lumen to permit passage of a(More)
PURPOSE To evaluate the Szabo technique in stenting at the vertebral artery ostium. METHODS Between 2010 and 2011, 26 patients (21 men; mean age 67 years) with symptomatic vertebral artery ostial stenosis >60% were treated. Under distal filter protection, a 0.014-inch guidewire was introduced in the ipsilateral subclavian artery as the marker wire for the(More)
