It was reported that slow flow occurred.The patient presented with recurrent chronic ischemia (rutherford 6) affecting the left lower extremity with gangrene of the left heel.A left lower extremity arteriography was performed via an antegrade left common femoral artery approach, with placement of a 7 french sheath.Left lower extremity arteriography demonstrated moderate to severe calcified atherosclerotic plaque within the mid and distal superficial femoral artery (sfa) with multifocal segmental stenoses, the greatest of which was greater than 90% reduction in luminal diameter.There were two vessel runoffs via a diminutive peroneal artery (dpa) and dominant runoff to the left foot via the anterior tibial artery (at) and dorsalis pedis (dp) arteries.There was a focal significant stenosis within the distal anterior tibial artery.A jetstream sc 1.6 mm device was utilized with blades down.Subsequently, embolic protection was deployed using an 8 mm non-boston scientific device into the popliteal artery.A jetstream 2.1 mm device was utilized with blades down.A 5 mm x 100 mm ranger dcb was then utilized to treat the left sfa.Follow up arteriography of the left sfa was performed during these procedures which demonstrated an excellent angiographic result; however, the below knee segment was only evaluated after removal of the embolic protection device and after ranger dcb.This demonstrated very slow flow in both the peroneal and anterior tibial arteries with occlusion of the distal ata and dpa.The physician tried to cross the ata from an antegrade approach which was unsuccessful.He performed successful retrograde dpa access ultimately reversing the access to perform vasodilator infusion, aspiration with a standard 4 f endhole catheter (not a dedicated aspiration catheter) and 2 mm in diameter angioplasty of the ata and dpa.Final arteriography demonstrated re-established patency of the ata and dpa with relatively slow flow and no washout into the pedal arteries.Post-procedure the patient foot was cool.The patient and family did not want additional intervention to be performed.Over the next 7 days, the leg became progressively ischemic which would have indicated an amputation, which the patient and family declined.By 14 days, the toes were dusky and blistering ensued.By 21 days, worsening gangrene occurred, now progressing through the calf.The patient expired 33 days post-procedure.
