摘要

Objectives

The aim was internal vascular centre quality-control measures to compare single-centre results with the national perspective, as well as analysing the Swedish results from carotid artery stenting (CAS) and comparing a relatively high-volume single centre with the Swedish Vascular Registry (Swedvasc) data. The second aim was to compare CAS and carotid artery endarterectomy (CEA) outcomes for the same 7-year period.

Design

Retrospective review of a single high-volume centre (S枚dersjukhuset (S脰S)) (approximately 30 CAS year^鈭? approximately 90 CEA year^鈭?) versus Swedvasc National data.

Materials and methods

All consecutive selective patients treated with CAS at S脰S for a stenosis of the internal carotid artery (n聽=聽208) or CEA (n聽=聽552) between 2004 and 2011 were compared with all patients in Swedvasc registered for CAS (n聽=聽258) and CEA (n聽=聽6474). Primary outcome was 30-day frequency of stroke or death. Secondary outcome was stroke/death/acute myocardial infarction (AMI).

Results

The 30-day frequency of any stroke or death after CAS at S脰S compared to the national data was 2.9%and 7.4%, respectively (P聽=聽0.04). The 30-day AMI/stroke/death frequency was 3.4%and 9.5%, respectively (P聽=聽0.01). After CEA during the same time period, the Swedvasc national data had a 4.4%frequency of 30-day stroke and death and 5.8%for AMI/stroke/death.

Conclusions

CAS is not as safe as CEA from a national perspective but our results indicate that a single centre can achieve acceptable results with CAS.
