Design: Case report.
Conclusion: Acquired injury to the right retro-splenial region can result in a specific variant of topographical disorientation known as heading disorientation that may present as an atypical transient ischaemic attack-like symptom heralding acute cerebral infarction.
METHODS: This is a cross-sectional study in which patients receiving IV alteplase in Hospital Universiti Sains Malaysia, from January 2017 to April 2020 were recruited. Demographical data, National Institutes of Health Stroke Scale (NIHSS) scores, door-to-needle time were recorded. Modified Rankin scale (mRS) scores were evaluated at 90 days after initial therapy. Good and poor functional outcomes were defined as 0-2 and 3-6, respectively.
RESULTS: A total of 30 patients were included in the study with a mean age of 59±11.47 years old. 76.7% of them were male and the rest were female. From the study, onset-toneedle time was 197.47±51.74 minutes, whereas door-toneedle time was 120.93±53.63 minutes. Seventeen (56.3%) patients achieved a favourable score of 0-2 on the mRS at 90 days after treatment. Haemorrhagic transformation occurred in eight (26.7%) of the patients with a mortality rate of 13.3%.
CONCLUSION: 56.7% of our patients showed improvement in the mRS at 90 days post thrombolysis for AIS. Higher baseline NIHSS scores and diabetes mellitus were associated with poorer functional outcomes after thrombolysis.
