Purpose: Temporary arterial occlusion (TAO) is a widespread practice in the surgical treatment of intracranial aneurysms. This study aimed to investigate TAO's role during ruptured aneurysm clipping as an independent prognostic factor on short- and long-term outcomes.
Methods: This prospective cohort included 180 patients with ruptured intracranial aneurysms and an indication of microsurgical treatment.
Neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios and prognosis after aneurysmal subarachnoid hemorrhage: a cohort study.

Background: Subarachnoid hemorrhage (SAH) prognosis remains poor. Vasospasm mechanism might be associated with inflammation. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been studied as inflammation markers and prognostic predictors.

- - The study aimed to assess risk factors influencing outcomes after treatment for aneurysmal subarachnoid hemorrhage (aSAH) in patients aged 18 and older.
- - Findings revealed that female gender, aneurysm location, and atherosclerotic plaque affected outcomes in the surgical treatment group, while age was the main factor for those treated endovascularly.
- - The results indicated that patients with atherosclerotic plaques and multiple aneurysms had poorer outcomes in surgery, while older age correlated with worse outcomes in endovascular treatment.
Purpose: To analyze the role of serum creatinine levels as a biomarker of intracranial aneurysm outcomes.
Methods: This is a prospective analysis of outcomes of patients with intracranial aneurysm. One hundred forty-seven patients with serum creatinine at admission and 6 months follow up were included.
Background: Temporary arterial occlusion (TAO) is a technique widely used in cerebrovascular surgery. However, few studies have evaluated the independent long-term effects of TAO or given detailed information about the complications during in-hospital stay.
Objective: This study aims to investigate the independent impact of TAO during unruptured intracranial aneurysm surgery on short and long-term outcomes.
