Abstract
BACKGROUND
Optic nerve sheath diameter (ONSD) measurement is one of the non-invasive methods recommended for increased intracranial pressure (ICP) monitoring.
AIM
This study aimed to evaluate the roles of optic nerve sheath diameter (ONSD) and ONSD/eyeball transverse diameter (ETD) ratio in predicting prognosis of death in comatose patients with acute stroke during their hospitalization.
METHODS
A total of 67 comatose patients with acute stroke were retrospectively recruited. The ONSD and ETD were measured by cranial computed tomography (CT) scan. All patients underwent cranial CT scan within 24 h after coma onset. Patients were divided into death group and survival group according to their survival status at discharge. The differences of the ONSD and ONSD/ETD ratio between the two groups and their prognostic values were compared.
RESULTS
The ONSD and ONSD/ETD ratio were 6.07 ± 0.72 mm and 0.27 ± 0.03 in the comatose patients, respectively. The ONSD was significantly greater in the death group than that in the survival group (6.32 ± 0.67 mm vs 5.65 ± 0.62 mm, t = 4.078, P < 0.0001). The ONSD/ETD ratio was significantly higher in the death group than that in the survival group (0.28 ± 0.03 vs 0.25 ± 0.02, t = 4.625, P < 0.0001). The area under the receiver operating characteristic curve was 0.760 (95%CI: 0.637-0.882, P < 0.0001) for the ONSD and 0.808 (95%CI: 0.696-0.920, P < 0.0001) for the ONSD/ETD ratio.
CONCLUSION
The mortality increased in comatose patients with acute stroke when the ONSD was > 5.7 mm or the ONSD/ETD ratio was > 0.25. Both indexes could be used as prognostic tools for comatose patients with acute stroke. The ONSD/ETD ratio was more stable than the ONSD alone, which would be preferred in clinical practice.
Core Tip: Optic nerve sheath diameter (ONSD) and ONSD/eyeball transverse diameter (ETD) were correlated with intracranial pressure and prognosis. This study aimed to evaluate the roles of ONSD and ONSD/ETD ratio in predicting prognosis of death in comatose patients with acute stroke during hospitalization. Total 67 comatose patients were retrospectively recruited. ONSD and ETD were measured by cranial computed tomography scans within 24 h after coma onset. It was found that the mortality increased when ONSD > 5.7 mm or ONSD/ETD ratio > 0.25. The ONSD/ETD ratio was more stable than ONSD alone, which be preferred in clinical practice.
