Abstract

Background: A spot sign on computed tomography angiography (CTA) is a potentially strong predictor of poor outcome on ultra-early radiological imaging. The aim of this study was to assess the spot sign as a predictor of functional outcome at 3 months as well as long-term mortality, with a focus on the ability to identify patients with a spontaneous, acceptable outcome. Methods: In a prospective, consecutive single-centre registry of acute stroke patients, we investigated patients with spontaneous intracerebral haemorrhage (ICH) admitted within 4.5 h after symptom onset from April 2009 to January 2013. The standard work-up in our centre included CTA for spot sign status, unless a contraindication was present. Modified Rankin Scale (mRS) scores were assessed at 3 months in the outpatient clinic or by telephone interviews. Long-term mortality was assessed by electronic chart follow-up for up to 1,500 days. Results: Of the 128 patients, 37 (28.9%) had a spot sign on admission CTA. The presence of a spot sign was associated with larger median admission haematoma volume [38.0 ml (IQR 18.0-78.0) vs. 12.0 ml (5.0-24.0); p < 0.0001] and higher median National Institutes of Health Stroke Scale score [19 (IQR 12-23) vs. 12 (6-16); p < 0.0001]. Three months after stroke, the median functional outcome was considerably better in patients without spot sign [mRS score 3 (IQR 2-4) vs. 6 (4-6); p < 0.0001]. The absence of a spot sign showed a sensitivity and specificity for good outcome (mRS scores 0-2) of 0.91 and 0.36, respectively. The presence of a spot sign was, in multivariate models, an independent inverse predictor of good 3-month outcome (OR 0.17; 95% CI: 0.03-0.88) as well as a prominent independent predictor of poor 3-month outcome (mRS scores 5-6; OR 3.40; 95% CI: 1.10-10.5) and death during follow-up (HR 3.04; 95% CI: 1.45-6.34). Patients with a spot sign surviving the acute phase had long-term survival comparable to patients with no spot sign. Conclusion: The absence or presence of a spot sign is a reliable ultra-early predictor of long-term mortality and functional outcome in patients with spontaneous ICH.
