(PDF) Endovascular thrombectomy for large vessel occlusion acute However, the implications for IMS 3 for mechanical thrombectomy may be limited, as many patients enrolled in the endovascular arm of IMS 3 were treated with intra-arterial fibrinolytics drugs rather than mechanical thrombectomy, essentially none of the patients were treated with the most technically efficacious device class, the stent retrievers, and the trial included large number of patients with no occlusions or small, distal occlusions, which are less likely to benefit from mechanical retrieval. Large arteries, not small: Mechanical thrombectomy devices work well in large, proximal arteries, rapidly debulking large clot burdens that are resistant to chemical fibrinolysis. This unique combination allows us to combine the best available tools and providers to quickly treat our patients and maximize recovery. A guide wire is The neurointerventionalist deploys the loops of the coil through the clot to engage the thrombus, and then pulls both coil and clot back into the catheter, like pulling a cork from a wine bottle. thrombectomy devices used with thrombolysis are more effective than thrombolysis alone in patients with acute ischaemic stroke.
