Summary
Slipped surgical clips can cause residual aneurysms in 21.8% of cases. Early and regular angiographic follow-up is crucial for managing these intracranial aneurysm complications.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Radiology
Background:
- Aneurysm rest occurs in 1-10% of operated patients.
- Slipped clips are a significant cause of residual aneurysms, accounting for 21.8% of cases.
Observation:
- Two female patients underwent microsurgical treatment for intracranial aneurysms without intra-operative complications.
- Post-operative angiography revealed clip displacement and recurrent aneurysms in both cases.
Findings:
- The study highlights the risk of clip migration leading to residual aneurysms.
- Literature review suggests specific follow-up protocols based on residual aneurysm size.
Implications:
- Emphasizes the need for vigilant post-operative monitoring of intracranial aneurysms.
- Suggests potential modifications to surgical techniques or clip selection to minimize migration risks.
