Cerebral aneurysms are diagnosed in 1-5% of people and cause 80-85% of subarachnoid hemorrhages (SAH). Aneurysmal hemorrhages are more common in people aged 30-50 years causing high socio-economic significance of this disease. Therefore, the outcomes of microsurgical clipping are an urgent problem in these patients.
To evaluate the immediate and long-term results after microsurgical treatment of cerebral aneurysms in acute period of hemorrhage; to analyze functional results and long-term outcomes, including higher mental functions and return to previous work.
The study included 517 patients in acute period of subarachnoid hemorrhage between 2019 and 2022. Severity of hemorrhage was assessed using the Hunt-Hess scale while the Fisher scale was valuable to estimate dimensions of hemorrhage and predictions for vasospasm. All patients underwent microsurgical clipping of aneurysms. We assessed clinical status and outcomes immediately after microsurgical clipping, within 2 weeks, 1, 3, 6 and 12 months after surgery. The Modified Glasgow Outcome Scale, Modified Rankin Scale (mRS), EQ-5D-3L Quality of Life Questionnaire, Mini-Mental State Examination MMSE and Hamilton Anxiety Rating Scale were used.
After 1 month, mRS score 0 was observed in 22% of patients, score 1 — 17%, score 2 — 19.4%, score 3 — 6.2%, score 4 — 2.6%, score 5 — 1% of patients. Mortality rate was 6.4%. After 12 months, mRS score 0, 1, 2, 3 and 4 was observed in 67%, 15%, 8%, 3% and 0.4% of patients, respectively. After 12 months, 39 (8.3%) patients did not return to previous work. Among 427 (91.7%) patients who returned to previous work, 20% returned to work after 3 months, 65% after 6 months and 15% after 9 months.
Short-term and long-term functional outcomes vary significantly. There were significantly better mRS scores in long-term period compared to early period. Analysis of immediate and long-term results after hemorrhage will allow us to determine the most important predictors of adverse functional outcomes, assess the prevalence, characteristics, modifiable risk factors and consequences of hemorrhage.
