Abstract :Ischaemic stroke is recognised as one of the common causes of disability and death today, and it is a primary reason for admission to intensive care units. Posterior circulation strokes account for 20-25% of ischaemic strokes. Respiratory failure is among the leading causes of mortality. Identifying risk factors may aid in taking preventive measures. This study aims to identify the risk factors associated with invasive mechanical ventilation in patients with posterior circulation stroke. This study included patients diagnosed with posterior circulation stroke by the Neurology Clinic at our tertiary centre between 01.01.2019 and 01.01.2021. It was designed to compare patients who required invasive mechanical ventilation with those who did not, and to identify associated risk factors. Independent risk factors for requiring invasive mechanical ventilation in patients with posterior circulation infarcts were found to be stroke-related pneumonia, basilar artery occlusion, and ischaemic stroke due to large artery disease. SOFA and APACHE II scores, along with 28-day mortality rates, were assessed in patients requiring invasive mechanical ventilation. 28-day mortality occurred in 6 patients. The mean SOFA score was 4.72 ± 2.72, and the mean APACHE II score was 19.88 ± 5.34. In this study, the need for invasive mechanical ventilation in posterior circulation strokes was associated with basilar artery occlusion, stroke aetiology being large artery atherosclerosis, presence of stroke-related pneumonia. The main limitation of this study is its retrospective design, and as it was conducted at a single centre, it may not reflect the wider population. Multicentre and prospective studies are necessary to address this issue.
