The patient was undergoing a thrombectomy procedure in the m1 segment of the middle cerebral artery (mca) using a penumbra system jet7 kit (kit).
During the procedure, the physician advanced the penumbra system jet 7 reperfusion catheter (jet7) over a non-penumbra guidewire up to the m1 occlusion through a neuron max 6f 088 long sheath (neuron max).
Next, the physician advanced the jet7 to the clot and turned on aspiration; however, after approximately two minutes, there was no flow of blood in the aspiration tubing.
Therefore, the physician started to retract the jet7.
Upon reaching the internal carotid artery (ica) terminus, the physician noticed that blood flow started to come through the aspiration tubing and, subsequently, observed that the vessel had recanalized.
After removing the jet7, it noticed that the coils at the distal tip of the jet7 were ¿unwound¿ and frayed.
The physician then performed a contrast run and noticed a hemorrhage just distal to the ica terminus where the distal tip of the jet7 had broken off and seated.
No attempts were made to retrieve the broken tip and the physician ended the procedure at this point.
Subsequently, the patient expired; however, the cause of death is unknown at this time.
Furthermore, the relationship between the fractured jet7 tip and death is unknown.
