Background: There are limited therapeutic options in cases of failed reperfusion (modified thrombolysis cerebral infarction [mTICI] score < 2b) after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence data supporting its use, rescue therapy (balloon angioplasty stent implantation) is often utilized such cases. Studies to large vessel occlusions, while outcomes and complications medium/distal occlusions (MDVOs) have not been...
Vessel perforation during thrombectomy is a severe complication and hypothesized to be more frequent medium vessel occlusion (MeVO) thrombectomy. The aim of this study was compare the incidence outcome patients with MeVO large (LVO) report on procedural steps that led perforation.
Background: There are limited therapy options in case of failed reperfusion after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence data supporting its use, rescue angioplasty (RA; with or without stent implantation) is often utilized such cases. Studies to large vessel occlusions, while outcomes and complications RA medium/distal occlusions (MDVOs) have not been reported. This study aims report MDVO stroke patients. Methods:...

During development, patients subject to using gadoterate meglumine post-contrast technique (TR/TE 3.3/1.6 ms; FoV320 × 320 mm; FA12°; Voxel1.1 1.1x2.5 mm) were matched into four equally-sized groups...
<h3>Introduction</h3> Rescue stenting is used more and in stroke cases with large-vessel-occlusion or medium-vessel-occlusion refractory to mechanical thrombectomy. The pEGASUS-stent(Phenox) represents a device which equipped hydrophilic polymer coating(HPC) antithrombogenic properties. coating allows for implantation under single antiplatelet therapy, thus possibly reducing the risk of bleeding acute cases. <h3>Case History</h3> A 79-year-old woman was rushed emergency room due left-sided...
<h3>Case report</h3> A 76-years old male patient presented 5 years after carotid stenting with ipsilateral recurrent high-grade stenosis, occlusion of the contralateral ICA and bilateral borderzone infarcts. progressive cuff calcification was identified compression distal stent (see figure 1).
