Rescue Extracranial Vertebral Stenting in Tandem Occlusions — REVET  

Acute Stroke Clinical Trial

Official title: Rescue Extracranial Vertebral Stenting in Tandem Occlusions

Status Completed

Clinical Trial Summary

The acute vertebrobasilar occlusion associated with the poor prognosis, particularly tandem occlusion. However, few data on the efficacy of the endovascular therapy was indicated in this occlusion. The investigators reported whether the additional rescue extracranial stenting improved clinical outcome by modified Rankin Scale (mRS) score within 3 months after the procedure

Clinical Trial Description

Acute vertebrobasilar artery occlusion is one of the cerebrovascular diseases with high disability and mortality rates. Although mechanical thrombectomy has recently been demonstrated an effective treatment for large vessel occlusions of posterior circulation, the treatment strategies depending on the specific pathophysiology. Tandem occlusion in posterior circulation is less frequently than in anterior one, comprises severe stenosis or occlusion of the extracranial vertebral artery ipsilateral to its intracranial and basilar occlusion. The recent studies showed the benefit of the "distal-to-proximal" approach, there were many tecniques to achieved the successful recanalization. Besides, the use of Dotter technique allowed 8F guiding catheter to cross the extracranial lesions easily and save the procedural time. However, the Diagnosis 5F-Dotter, like the Dilator-Dotter, has not been mentioned in previous studies. Therefore, the aim of the our study was to assess the improvement of outcomes at 3 months posttreatment in patients receiving rescue extracranial vertebral stenting ;
