Abstract | BACKGROUND: CASE DESCRIPTION: A 79-year-old man suddenly developed somnolence, global aphasia, and right hemiplegia. Magnetic resonance imaging revealed acute infarction of the left frontal lobe and occlusion of the left common carotid artery. Thus, using an aspiration catheter and a stent retriever, mechanical thrombectomy was performed. The stent retriever was deployed from the middle cerebral artery to the internal carotid artery and retracted into the aspiration catheter placed in the internal carotid artery proximal to the thrombus. The catheter was bent during retraction of the stent retriever. After thrombus aspiration, the internal carotid and anterior and middle cerebral arteries were successfully reperfused; however, the stent retriever captured a broken section of the winding coil of the aspiration catheter. We suspected that an X-ray marker on the stent retriever broke the winding coil at the bent segment of the aspiration catheter and the stent captured the broken coil. CONCLUSIONS: The combined use of an aspiration catheter and a stent retriever may cause unexpected device breakage, especially when the catheter is bent.
