A Commentary on 'Diagnose Vessel Course Distal to Occluded Artery using Heavily T2-weighted MRI in Mechanical Thrombectomy

In endovascular thrombectomy for acute ischemic stroke due to large-vessel occlusion, occluded vessels are invisible on MRA or DSA. Heavily T2-weighted MRI sequence, which offers good contrast between cerebrospinal fluid and other brain structures, may contribute to resolve this issue. In this study the efficacy of this sequence in estimating vessel courses including unexpected aneurysms of the portion more distal to the occlusion site in endovascular thrombectomy is evaluated from the point of reliability, feasibility, and contribution to safety and also the detectability of aneurysms [1-4]. The heavily T2-weighted MRI sequence can contribute to improving the safety of maneuvers by clarifying the course of occluded vessels in endovascular thrombectomy for large-vessel occlusion [5].
