Introduction: Cervical artery dissection (CAD) is the cause of 2% to 3% of ischaemic strokes and 10% to 25% of the ischaemic strokes in young people. Our objective is to evaluate whether implementation of a comprehensive stroke centre (CSC) improves the diagnosis and modifies the prognosis of patients with acute stroke due to CAD.
Patients and methods: Retrospective study of a registry of consecutive patients with acute stroke due to CAD. They were classified according to the period of care at our centre: pre-CSC (October 2004-March 2008, 42 months) or post-CSC (April 2008-June 2012, 51 months). We compared baseline characteristics, methods of diagnosis, treatment and outcome of these patients in both periods.
Results: Nine patients were diagnosed with CAD in pre-CSC and 26 in post-CSC, representing 0.8% and 2.1% of all ischaemic strokes treated in each period, respectively. The diagnosis of CAD was made within the first 24 hours in 42.3% of the patients in post-CSC versus 0% in pre-CSC, by using urgent cerebral angiography as a diagnostic test in 46.2% of cases in the second period compared to 0% in the first. Both severity of stroke (median NIHSS score 11 vs. 3, P=.014) and time to neurological care (265 min vs 148, P=.056) were higher in the post-CSC period. Endovascular treatment was performed in 34.3%, and all treatments were post-CSC. The functional outcome was comparable for both periods.
Conclusions: Implementation of a CSC increases the frequency of the diagnosis of CAD, as well as the treatment options for these patients in the acute phase of stroke.
