The patient was undergoing a thrombectomy procedure in the middle cerebral artery (mca) using a velocity delivery microcatheter (velocity), penumbra system jet7 reperfusion catheter (jet7), penumbra pump, penumbra canister, non-penumbra guiding catheter, and non-penumbra stent retriever. During the procedure, the physician placed the velocity, jet7, and guiding catheter in the m1 segment and performed aspiration using the jet7. It was noted that the jet7 was connected to the pump, and the canister was placed in the pump. The physician stopped aspirating once blood was seen flowing into the canister. Subsequently, the physician flushed the jet7 with a 10cc syringe to perform an angiogram, which showed there were remaining clots in the m2 to m3 segments. The physician then re-advanced the same velocity through jet7, followed by a stent retriever. The jet7 was used aspirate the remaining clots. Next, the stent retriever was removed, but there was no blood flowing into the canister, so the physician decided to retract the jet7. While retracting the jet7 slowly, the physician continued aspiration until it was close to the acute-stage cerebral infarction. Subsequently, the jet7 was flushed with a 10cc syringe again to perform another angiogram. However, while flushing the jet7, the distal tip was kicked to the m1 segment and expanded. Contrast media was noticed in that segment. It was noted that second angiogram showed there were remaining blood clots. Upon removal of the jet7, damage on the distal tip was observed. The physician ended the procedure at this point. To treat the bleeding in the mca, the physician placed eight non-penumbra coils. On (b)(6) 2020, the patient? S condition was classified as mrs5 on the modified rankin scale (mrs). On (b)(6) 2020, the patient expired.
