The patient was undergoing a thrombectomy procedure to treat a large vessel occlusion (lvo) in the left m1 segment of the middle cerebral artery (mca) using a penumbra system red72 reperfusion catheter (red72), a neuron max 6f 088 long sheath (neuron max), a non-penumbra stent retriever and a guidewire.During the procedure, the physician deployed the stent retriever and completed one pass using the red72.After completion of the first pass, the physician retracted the stent retriever through the red72.While retracting the red72, the physician experienced resistance and noticed under fluoroscopy that the red72 was fractured at the distal length.The physician then attempted to aspirate the fractured distal segment of the red72 using a new red72 but was unable to retrieve it.The procedure ended at this point.
