Overview
The rescue carotid stenting has recently been an additional treatment followed by mechanical thrombectomy in tandem occlusions of the anterior circulation. Nevertheless, there were few data to date that support this beneficial treatment in Asia. The investigators hypothesized that this treatment related to improvement of clinical outcomes after procedure.
Description
The anterior circulation made commonly up 70-80% of all ischemic strokes. The mechanical thrombectomy is the gold treatment standard in acute ischemic stroke due to large vessel occlusion of anterior circulation. Tandem occlusions are one of the acute lesions relating to the high poor clinical outcome rate. Besides, tandem characteristic is a challenge to perform endovascular therapy and save procedural time in the restoration blood flow to the cerebral artery territory infarction. Many studies mentioned rescue carotid stenting with two approaches (such as proximal-to-distal and distal-to-proximal) with this lesion and the intracerebral hemorrhage after the successful recanalization. However, few studies compared the pros and cons of each approach. Therefore, the investigators conducted this study to assess the roles of approaches with rescue carotid stenting in the tandem occlusions to improve clinical outcomes at 3 months.
