Percutaneous transluminal angioplasty versus surgery for subclavian artery occlusive disease.
Twenty-one patients who underwent percutaneous transluminal angioplasty (PTA) for proximal stenosis of the subclavian artery were compared with 15 patients who underwent carotid subclavian reconstruction. This represents the first attempt to directly compare the two procedures. All patients had routine Doppler examination during follow-up. Mean follow-up was 30 +/- 24 months after PTA and 40 +/- 25 months after surgery. The incidences of procedural complications were similar (PTA one complication, surgery two complications). Although better early results were achieved in patients who underwent PTA (actuarial patency: PTA 91 percent, surgery 87 percent), after dilatation, we observed a continuous deterioration of the hemodynamic status of the artery, which led to a high rate of late restenosis (actuarial patency: PTA 54 percent, surgery 87 percent). There were no significant changes postoperatively. The specific role of each procedure is analyzed in view of the new acknowledgment of the clinical importance of proximal subclavian artery disease.
