Introduction: Despite evidence based institutional protocols being in place in many countries, aneurysmal subarachnoid hemorrhage (SAH) continues to be a major socio-economic burden with many open questions remaining regarding the optimal management of the affected patients. Aims: Our aim was to put together a retrospective aneurysmal SAH registry, in order to obtain a cross-section of the patients reffered to or treated at our Insitution. The goal was to both obtain data regarding these patients and to design a prospective registry based on the collected information.

Methods: We retrospectively collected and reviewed the data from our electronic admission forms and electronic on-call reports. All patients with aneurysmal subarachnoid hemorrhage and non-aneurysmal perimesencephalic hemorrhage reffered to or admitted in our Department were considered. We analysed geo-demographic data (refferring hospital, referral time, age, sex) as well as onset of symptoms-referral/treatment interval, Hunt and Hess and Fisher grades, treatment method (surgical or endovascular), aneurysm charectiristics (localisation, dome/neck ratio, multiplicity), complication rate (general and specificvasospasm, hydrocephalus), time spent in Intensive Care Unit, mortality rate, status at discharge (modified Rankin Scale).

Results: We found and analysed the data from 1355 patients referred to or admitted in our Department during 2014-2022. The patients predominantly received endovascular treatment. 

Conclusion: Based on our data, we propose a prospective SAHRegistry where, in addition to the data we collected from the retrospective one, it is imperative to include follow-up data at at least 3 and 6 months. In addition, we should work towards a national and at least South-East European unified registry in order to compare our institutional protocols and outcomes for the benefit of our patiens.
