				        	 Mechanical thrombectomy using a stent retriever is a widely-used technique for recanalizing occluded cerebral arteries in acute ischemic stroke. Although rare, inadvertent stent detachment has primarily been reported with earlier stent retriever designs. We present 2 cases of inadvertent stent detachment with the pRESET stent. In the first case, an elderly patient presented with right middle cerebral artery occlusion and experienced stent detachment during the second retrieval. Despite this, successful recanalization was achieved through balloon angioplasty. In the second case, an elderly patient experienced stent detachment after the third retrieval, and recanalization of the M1 segment was unsuccessful due to the inability to pass the microcatheter. The first patient had a modified Rankin scale (mRS) score of 3, while the second had a poor prognosis with an mRS score of 5. These cases highlight that inadvertent stent detachment can impact outcomes, and balloon angioplasty may serve as a useful salvage therapy.
