Abstract

In acute ischemic stroke, various endovascular approaches have been reported with high recanalization rates and good clinical outcomes. However, the best device or technique for the first attempt at mechanical thrombectomy remains a matter of debate. We report a case in which endoluminal injury from initial stent clot retrieval possibly caused repeated middle cerebral artery occlusion. A 74-year-old man presented with left-sided hemiplegia and was diagnosed with a right internal carotid artery occlusion. He underwent endovascular thrombectomy using a stent clot retriever. Although complete recanalization was achieved in the first pass, repeated middle cerebral artery occlusion occurred. Angiography revealed an irregular inner surface and thrombus formation in the superior branch of the second segment of the right middle cerebral artery. There is a risk of endoluminal injury due to stent retrieval, especially using a large sized stent against small branches. Antiplatelet therapy may be effective for preventing recurrent occlusion.

Key Messages We report a case in which endoluminal injury from initial stent clot retrieval possibly caused repeated middle cerebral artery occlusion. There is a risk of endoluminal injury due to stent retrieval, especially using a large sized stent against nonvisible small branches.
