Carotid artery stenting shown to be cost-effective alternative to endarterectomy
Date:3/3/2011

complication who were then randomized and underwent CAS (n=159) or END (n=151). Researchers prospectively assessed clinical outcomes, resource use, costs and quality of life for all participants over a one-year period following the procedures.

"Our findings show that CAS with embolic protection offers a cost-effective alternative treatment option for patients with carotid artery atherosclerosis who are at high risk of adverse events with END," noted Dr. Cohen. Study results showed initial procedural costs were significantly higher for stenting ($7,000) than for END ($3,000). However, post-procedure hospital stay was one day shorter for CAS which reduced associated costs, resulting in initial costs for stenting being only $559 per patient higher than for END. Follow-up costs after discharge and total one-year costs did not differ between the two procedures.

Researchers also found after the first year, the rates of death, heart attack, major stroke and repeat carotid revascularization were lower with CAS compared with END (7% vs. 13%; 3% vs. 8%; 0.6% vs. 4%; 0.6% vs. 4%). Follow-up medical costs were $810 higher for stenting. "CAS appears to be a highly cost-effective option for high surgical risk patients," concluded Dr. Cohen. "Results should not be generalized to patients at low surgical risk, however. Further studies are needed to assess efficacy and cost-effectiveness of CAS in this patient population."
