<p><strong>Objectives</strong>: 1. Investigate the relationship between atmospheric pressure changes and the occurrence of intracranial aneurysm (IA) rupture.2. Aiming to determine if variations in atmospheric pressure contribute to IA rupture.</p><p><strong>Background</strong>: Spontaneous subarachnoid hemorrhage (SAH) has an annual incidence of approximately 10-20 per 100,000, predominantly attributed to the rupture of intracranial aneurysms (IA), accounting for about 85% of cases. This study aims to investigate the potential relationship between IA rupture and climate, and time-related factors.</p><p><strong>Methods</strong>: We conducted a retrospective analysis of cases presenting with SAH due to aneurysm rupture in 2023. Patient records were reviewed, the demographic data, Fisher Grade, Bleeding Time (including time of day, month, and season), as well as daily average and maximum atmospheric pressure (HPA) values from İzmir province were gathered. The Mann- Whitney U test was used to asses pressure values with SAH occurrence.</p><p><br></p><p><strong>Results</strong>: Total of 51 cases with an average age of 53.8 years (range: 23-85), with 53% male was found. Most of the cases (39%) were referred from other centers to our intensive care unit at the 16:00-08:00 time interval. The most common location of aneurysms was the anterior communicating artery (37%). Fisher Grade 4 SAH was observed in 69% of cases. Bleeding time predominantly occurred between 18:00 and 24:00 (31%), during autumn (31%), in September (13%), on weekdays (67%), and particularly on Mondays (21%). Pressure value changes were notably higher in patients with hypertension and Fisher Grade 4 bleeding. PMAX on the day of bleeding correlated with PMAX, port pressure, and one-day maximum pressure change (ΔPax) values, with statistical significance (p < 0.05).</p><p><strong>Conclusions</strong>: Our findings suggest a potential association between average pressure changes, Fisher grade, possibly linked to temperature decreases during seasonal transitions and evenings, coupled with increased atmospheric pressure. However, larger-scale, multi-centered studies are warranted to validate these findings further.</p>
