Insights
Management of aneurysmal subarachnoid hemorrhage (SAH) in elderly patients has shifted towards interventional treatments, improving outcomes. This study highlights the increasing use and effectiveness of these modern approaches in older populations.
Area of Science:
- Neurosurgery
- Interventional Neurology
- Geriatric Medicine
Background:
- Aneurysmal subarachnoid hemorrhage (SAH) poses significant risks, particularly in elderly patients (over 70 years).
- Recent advancements in neurosurgical and endovascular techniques offer new management possibilities for this demographic.
- Evaluating treatment trends and outcomes in advanced age SAH is crucial for optimizing patient care.
Purpose of the Study:
- To analyze recent management strategies for aneurysmal subarachnoid hemorrhage (SAH) in patients over 70 years old.
- To compare treatment approaches and outcomes between early (2001-2005) and late (2006-2009) periods.
- To assess the impact of evolving treatment modalities on patient outcomes in advanced age SAH.
Main Methods:
- Retrospective analysis of 372 aneurysmal SAH cases, including 123 elderly patients, treated between January 2001 and July 2009.
- Division of patients into two groups based on treatment period: 2001-2005 and 2006-2009, with a focus on interventional treatment selection since 2006.
- Analysis of Hunt-Kosnik (HK) grade, treatment methods, vasospasm rates, Glasgow Outcome Scale (GOS) at 30 days, and shunt operation ratios, using chi-square and t-tests for statistical analysis.
Main Results:
- The proportion of interventional procedures in elderly patients increased significantly from 28% to 38%.
- Coil embolization rates rose from 8% to 24%, and angioplasty rates increased from 22% to 76%.
- Favorable outcomes (GOS) improved from 47% to 51%, while the rate of shunt surgeries decreased from 33% to 19%.
Conclusions:
- Despite an increasing mean age and procedural shift towards interventional methods in elderly SAH patients, outcomes have improved.
- Aggressive prevention and treatment of vasospasm, alongside acute-stage aneurysm treatment, are key to these positive results.
- Interventional treatment strategies are essential for enhancing outcomes in advanced-age aneurysmal SAH cases.
Purpose:
we focused on the recent management of aneurysmal subarachnoid hemorrhage (SAH) in patients over 70 years old (advanced age).
Methods:
from January 2001 through July 2009 we treated 372 aneurysmal SAH cases including 123 patients of advanced age. Since 2006 we have been selecting primarily interventional treatment in advanced age. We divided patients into two groups: from 2001 to 2005 and from 2006 to 2009. We analyzed Hunt-Kosnik (HK) grade, treatment methods, rate of vasospasm, Glasgow Outcome Scale at 30 days after onset of SAH, and the ratio of shunt operations. Statistical analyses were done with chi-square analysis or the t-test.
Results:
the ratio of procedures in advanced age increased statistically from 28% (51/183) to 38% (72/189). Mean age of patients increased from 76.2 to 77.7. HK grade and proportion of radical surgeries were similar. But the proportion of acute stage surgery and coil embolization increased significantly from 79 to 95% and from 8 to 24%, respectively. Incidence of symptomatic vasospasm increased from 35 to 37%, while asymptomatic vasospasm decreased from 4.7 to 3.2%. Rate of angioplasty increased significantly from 22 to 76%. The proportion of shunt surgeries decreased from 33 to 19% and favorable outcomes increased from 47 to 51%.
Conclusions:
mean age and proportion of procedures in advanced age are increasing, but outcomes have improved. These results depend on radical surgery for aneurysm in the acute stage and aggressive prevention and treatment of vasospasm. Interventional treatment is necessary to improve the outcome in cases of advanced age.
