Prior to the introduction of percutaneous transluminal angioplasty (PTA), bypass grafting or endarterectomy was the treatment of choice for aortoiliofemoral atherosclerotic occlusive disease. Currently, PTA is a well-established procedure for the treatment of aortoiliofemoral atherosclerotic occlusive disease. PTA is as effective as, and safer than, surgery in these cases. Percutaneous transluminal angioplasty and endarterectomy cause similar trauma to the arterial wall, i.e., intimal denudation, plaque disruption and splitting, and medial disruption, splitting, and overstretching. Both PTA and endarterectomy heal in a similar manner, i.e., neointima formation and scarring. Both PTA and endarterectomy can be repeated. Therefore, PTA can be performed after endarterectomy or vice versa. Several patients with recurrent occlusive disease after endarterectomy have been safely treated with PTA. Our results obtained with PTA in patients who had a prior endarterectomy are comparable to the results obtained in patients who did not have a prior endarterectomy. No complications have been encountered. A previous endarterectomy does not preclude a subsequent PTA, or vice versa, in patients with recurrent occlusive disease. |
