It was reported that failure to evacuate occurred.The 99% stenosed target lesion was located in a mildly tortuous and severely calcified superficial femoral artery (sfa).A 1.6mm jetstream xc catheter was selected for a sfa dilation procedure.The catheter was placed with a thruway guidewire.After the third cutting, the evacuation function failed.The device was removed and primed again; however, saline did not flow through the device due to a suspected blockage.There were no patient complications, and the case was completed with a different device of a different model.
