Hypodensities within hematoma predict outcome after spontaneous intracerebral hemorrhage

Abstract

Background and objective:
 Not much is known about the prevalence and significance of hypodensities within hematoma after spontaneous intracerebral hemorrhage (ICH). The objective of this study was to determine the prevalence of hypodensities within hematoma after spontaneous ICH and their significance to predict poor outcome after ICH.
 Methods:
 This observational cross sectional study was conducted in the Department of Neurology, Pakistan Institute of Medical Sciences, Islamabad, from October 2021 to June 2022. Total 140 patients of acute stroke were included. Inclusion criteria was any patient of >20 years of age with confirmed diagnosis of ICH on imaging, non-traumatic, who presented within 24 hours after onset of symptoms. Data was analyzed by SPSS ver.23.0.
 Results: 
 Total 150 patients were included in the study. The mean age of patients was 52.28 ± 1.29 years. There were 100 (71.4%) males and 40 (28.6%) females. Hypertension was the most common comorbid present in 87 patients (62.1%).55% of patients had on presentation National Institute of Health Stroke Scale (NIHSS) and modified Rankin Scale score of moderate severity. The mean ICH score on presentation was 2.64 +1.26. Hematoma expansion was present in 55(39.3%) patients while interventricular extension was seen in 100(71.4%) patients. Hypodensities were seen in 125(89.3%) patients( p value 0.001). When hematoma volume were compared in both groups it was also significant (p value 0.002).
 Conclusion: 
 We conclude that hypodensities within hematoma are a reliable marker of hematoma expansion after spontaneous ICH. Such reliable marker can be easily employed in resource-poor countries where CT angiography is not available everywhere. The higher NIHSS score and low GCS are significantly associated with hypodensities within hematoma.
