Summary
For ruptured brain aneurysms where standard treatment failed, surgical wrapping provided favorable long-term results. Complete wrapping or wrapping residual portions after clipping/ligation significantly reduced rerupture risk.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Neurology
Background:
- Ruptured aneurysms pose significant risks.
- Standard treatments like clipping or ligation are not always feasible.
- Alternative techniques are needed for complex cases.
Purpose of the Study:
- To evaluate the long-term efficacy of surgical wrapping for ruptured aneurysms when standard treatments were not possible.
- To assess the outcomes of different wrapping techniques.
Main Methods:
- Retrospective review of 44 patients who underwent surgical wrapping for ruptured aneurysms between 1961 and 1986.
- Analysis of long-term follow-up data, focusing on rerupture rates.
- Comparison of outcomes based on wrapping technique (complete wrapping, wrapping with clipping/ligation).
Main Results:
- Surgical wrapping was employed in 52 (2.7%) of 1903 ruptured aneurysm cases.
- Long-term results were studied in 44 cases.
- Only two cases with incomplete wrapping experienced rerupture, indicating high efficacy for complete or combined techniques.
Conclusions:
- Complete surgical wrapping is an effective treatment for ruptured aneurysms when standard neck clipping or ligation is not feasible.
- Wrapping residual portions after aneurysmal body clipping or ligation yields favorable long-term outcomes.
- Surgical wrapping offers a viable alternative with a low rerupture rate.
