Summary
Endovascular embolization is a viable alternative for treating complex internal carotid artery (ICA) aneurysms at the C3 segment. This minimally invasive approach achieved sufficient obliteration in all three patients studied.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Vascular Neurology
Background:
- Direct surgical treatment for C3 internal carotid artery (ICA) aneurysms presents significant procedural complexity.
- Aneurysms in this specific ICA segment pose unique challenges due to their location and associated risks.
Purpose of the Study:
- To evaluate the efficacy and safety of endovascular embolization as an alternative treatment for C3 ICA aneurysms.
- To present a case series of patients treated with endovascular techniques for these challenging aneurysms.
Main Methods:
- Three patients diagnosed with C3 ICA aneurysms were treated using endovascular embolization.
- The remodelling technique was employed in two cases involving unruptured aneurysms.
Main Results:
- Complete or sufficient obliteration of the aneurysms was achieved in all three treated patients.
- The endovascular approach proved effective in managing these complex cerebrovascular lesions.
Conclusions:
- Endovascular embolization represents a crucial alternative to open surgery for C3 ICA aneurysms.
- This technique offers a less invasive option with successful outcomes for complex aneurysm treatment.
