Objectives And Design:
Undelayed investigation and surgical treatment of symptomatic carotid artery stenosis are recommended as per guidelines on stroke prevention. We evaluated patient referral pathways and delays from symptom to surgery in Helsinki University Central Hospital (HUCH) region.
Materials And Methods:
One hundred consecutive symptomatic patients scheduled for carotid endarterectomy (CEA) between August 2007 and September 2008 were identified and the delay between ischaemic index symptom and CEA was analysed.
Results:
The median time from the index symptom to surgery was 47 days (range: 3-688 days). The longest delay was surgery related with a median of 25 days (range: 2-202 days) from the consultation of the vascular surgeon to the operation. Only 11% of the patients were operated within the recommended 2 weeks' time. It was more likely that CEA was performed within 2 weeks if an emergent consultation to Meilahti Hospital neurologist on call did take place (odds ratio (OR) 12.6, 95% confidence interval (CI) 1.5-104, p = 0.019).
Conclusion:
Delays from symptom to surgery were generally too long and the in-hospital door-to-knife time (DKT) was long mostly due to waiting for the operation theatre. The investigation of all stroke, amaurosis fugax and transient ischaemic attack patients should be performed on an emergency basis and most optimally centralised to hospitals were carotid surgery is performed.
