Background and purpose Physicians treating patients with posterior circulation strokes (PCS) tended to debate more on whether or not to introduce anticoagulation rather than performing investigations to identify stroke aetiology, as in patients with anterior circulation strokes (ACS). Recent findings suggest that stroke aetiologies of PCS and ACS are more alike than dissimilar, suggesting that PCS deserve the same investigations as ACS. The characteristics and current diagnostic evaluation between patients with PCS and ACS were compared.Methods 312 consecutive patients with first ever ACS and 93 patients with first ever PCS were prospectively analysed.Results Patients with ACS and PCS did not differ in terms of demographic characteristics, prevalence of vascular risk factors, diagnostic evaluation or stroke aetiology. The median National Institutes of Health Stroke Scale score was 8 in ACS and 4 in PCS (p=0.004). Brain imaging revealed more often pathological findings in ACS than PCS. The proportion of non-thrombolysed patients with a favourable clinical outcome (modified Rankin score 0-2) was similar in ACS and PCS (67.0% vs 78.4%; p=0.08). In non-thrombolysed patients, stroke severity was an independent predictor of clinical outcome both in ACS (OR 1.60, 95% CI 1.2 to 2.1; p
