[Recent results of carotid stenting for treatment of extracranial carotid occlusive disease].

OBJECTIVE

To analyze the recent results of CAS performed by vascular surgeons to treat extracranial carotid occlusive disease (ECOD) retrospectively in a single medical center.

METHODS

Forty-eight carotid arteries underwent CAS. Procedures were transfemoral. The postoperative follow-up was separated to 2 periods (<or=30 d and >30 d). The mortality and all kinds of complications were analyzed.

RESULTS

91.7% of them were men; 8.3% were women; mean age was (70.6 +/- 5.9) years. Preoperative asymptomatic cases were 37.5%; symptomatic cases were 62.5%. Mean internal carotid artery diameter stenosis was (71.2 +/- 14.8)%. 43.8% patients had single preoperative risk factors; two or more of these risk factors were present in 47.9%. In 33.3% cases the contralateral carotid artery had 50% or greater stenosis or was completely occluded. Technical success was achieved in 100%. There were no death, no major or minor stroke but 4.2% TIA. Carotid sinus compression syndrome occurred in 18.8% of patients. At follow-up > 30 days, there had been 4.2% instances of in-stent recurrent stenosis great than 50%, noted by color doppler ultrasound scanning. No stent deformity happened.

CONCLUSION

CAS can be preformed safely enough in patients with ECOD at high CEA risk, with lower perioperative morbidity and mortality.
