CT Blend Signs are not Associated with Poor Outcome in Patients with ICH Following a Stereotactic Minimally Invasive Surgery

Abstract

<jats:title>Abstract</jats:title> <jats:p><jats:bold>Backgrounds: </jats:bold>The initial CT blend sign has been used as an imaging maker to predict haematoma expansion and poor outcome in patients with small volume intracerebral haemorrhage (ICH). However, the relationship between the blend sign and the outcome of patients remains elusive. The present study aimed to retrospectively observe the impact of initial CT blend signs on the short-term outcome of patients with hypertensive ICH underwent a stereotatic minimally invasive surgery (sMIS). <jats:bold>Methods:</jats:bold> Two hundreds and forty-two patients with spontaneous ICH were enrolled. Based on the initial CT features, the patients were assigned to a blend sign group (including 91 patients) or a non-blend sign group (control group, including 151 patients). The NIHSS, GCS and the mRS were used to observe the efficacy of the sMIS. The rates of severe pulmonary infection, cardiac complications were also compared between the two groups. <jats:bold>Results: </jats:bold>No significant differences in NIHSS and GCS in one week or two weeks after surgery were observed between the two groups. The proportion of patients with good outcome during follow-up did not show any difference between the two groups. However, both the two groups displayed good functional outcome over admission. The rate of rehaemorrhage increased in the blend sign group. No significant differences in severe pulmonary infections and cardiac complications were noted between the two groups. <jats:bold>Conclusions：</jats:bold>The initial CT blend sign are not associated with poor outcome of patients with hypertensive ICH underwent sMIS. ICH patients with CT blend sign should be also treated by performing sMIS if they are candidates for surgery.</jats:p>
