Abstract [en]

Objectives: Current European Society for Vascular Surgery guidelines recommend that patients with a symptomatic carotid stenosis should be operated on within 14 days of onset of symptoms. Recent reports indicate that carotid endarterectomy (CEA) within 2 days of a neurological event may be associated with a higher. pen-procedural risk of stroke. Whether urgent carotid artery stenting (CAS) carries a similar high risk is unclear. The aim of this study was to analyze if urgent CAS increases the pen-procedural risks. Methods: Retrospective analysis of all CAS registered in Swedvasc, a validated nationwide registry, between January 1, 2005, and March 20, 2014. Only symptomatic patients treated for a stenosis of the internal carotid artery were included. Patients were categorized according to time from index event to surgery; 0-2 days, 3-7 days, 8-14 days, and 15-180 days. Primary outcome was 30 day combined stroke and death rate. Results: 323 patients underwent CAS for symptomatic carotid artery stenosis. The demographic and clinical data were similar in the groups. No procedure related complications or deaths were observed in the urgent CAS group. The 30 day combined stroke and death rate did not differ significantly between the groups; zero of 13 (0%; 95% Cl 0-26.6) in the group treated 0-2 days versus four of 85 (4.7%; 95% Cl 1.5-11.9), at 3-7 days, five of 80 (6.3%; 95% Cl 2.4-14.1) at 8-14 days, and six of 145 (4.1%; 95% Cl 1.7-8.9) for the patients treated at 15-180 days (p = .757). Stroke and death were not more frequent for patients treated within 1 week compared with after 1 week: 4 out of 98 (4.1%; 95% Cl 1.3-9.0) versus 11/225 (4.9%; 95% Cl 2.7-8.6) (p = .751). Conclusions: In this national registry study, CAS performed within 1 week of the onset of a neurologic event Was not associated with an additional risk of a pen-operative complication compared with those treated subsequently.
