Objective: To evaluate the demographic distribution and the long-term surgical outcomes of intracranial aneurysms (IAs) at a tertiary health institute. Method: I retrospectively reviewed the medical records of 398 patients with IAs who underwent surgical intervention at our tertiary health institute within 3 years, between 2011 and 2013. The demographic distribution regarding the patients’ cities and their long-term surgical outcomes were evaluated. Results: Sixty-one (36 females, 25 males) patients were from Istanbul. Majority (14.6%) of our patients (n=120: 71 females, 49 males) with IAs came from the Marmara region. The locations of IAs in our patients with subarachnoid hemorrhage (SAH) were antrerior communicating artery (AcoA) (n=78), middle cerebral artery (MCA) (n=74), multiple aneurysms (67), internal cerebral artery (ICA) (n=24), posterior communicating artery (PcoA) (n=13), anterior cerebral artery (ACA) (n=7), superior cerebellar artery (SCA) (n=6), and posterior cerebral artery (PCA) (n=5), whereas the locations of incidentally diagnosed IAs were MCA (45), ACoA (32), multiple (23), ICA (22), PCoA, ACA, and PCA one each artery. The mortality and morbidity rates were higher in SAH patients 16.7% - 10.6% (15% - 3% in patients with incidentally diagnosed IAs). The rate of the patients who returned to their normal daily activities was higher. Conclusion: A higher rate of postoperative hydrocephalus was observed in patients with multiple aneurysms. There was no relation between sex and morbidity and mortality rates. SAH patients presented with multiple aneurysms had a higher morbidity rate. Advanced age (> 65) and MCA location were associated with a higher mortality rate, while locations of ICA (especially ophthalmic), PCoA, and ACoA were associated with a higher morbidity rate.
