The anatomic basis for the occasional failure of transfemoral balloon catheter thromboembolectomy.
A Fogarty balloon catheter was advanced from the common femoral artery through the popliteal artery and its branches in 15 cadavers. The catheter passed into the peroneal branch 89% of the time. In all 15 cadavers, the peroneal artery was the direct continuation of the popliteal artery and the arterior tibial and posterior tibial arteries branched off at varying angles from the popliteal. This provides an anatomic explanation for the occasional failure of transfemoral Fogarty catheter embolectomy of the leg. Our study suggests that if the patient's foot does not improve after Fogarty embolectomy, the popliteal artery should be exposed and the catheter directed into the shank arteries using vascular forceps.
