Endovascular thrombectomy after large-vessel ischaemic stroke: A meta-analysis of individual patient data from five randomised trials. The image artifact extends approximately 2 mm from the device, both inside and outside the device lumen. Metallic stents may indeed undergo heating during RF-excitation, but this also does not seem to be a major problem even with overlapping stents or with big aortic stent-grafts, in part because flowing blood serves to diffuse away whatever heat is locally generated. More information (see more) ObjectivesThe stent retriever thrombectomy (SRT) and a direct aspiration first-pass technique (ADAPT) are the two main mechanical thrombectomy (MT) techniques for acute ischemic stroke. The appropriate anti-platelet and anti-coagulation therapy should be administered in accordance with standard medical practice. This was the first successful human clinical use of a Solitaire stent for this purpose and the ignition spark for the development of a whole generation of new devices, now called stent .

Mueller-Kronast NH, Zaidat OO, Froehler MT, et al. Although the authors blamed the MRI for the displacement, subsequent letters to the editor cast doubt on this assertion, providing evidence that the original stent was poorly chosen and placed and that spontaneous displacement of similarly placed stents had been reported in the absence of MRI.
