Half-Trevo technique. A: Initial angiography showing left M2 occlusion. B: After deployment of the Trevo ProVue, fluoroscopy demonstrated satisfactory configuration of the stent retriever wall, although the unsheathing length of the microcatheter was half the size of the whole stent retriever component. This partial deployment of the stent retriever, the “Half-Trevo technique,” could shorten the length of stent retriever deployment at a tortuous vessel with a short clot lesion. This technique might contribute to the relief of stress placed on tortuous vessels. C: After retrieval of the Trevo ProVue, the clot was removed with the stent retriever. D: After mechanical thrombectomy, angiography showed successful revascularization.
