Summary
Temporary balloon occlusion aids complex basilar trunk aneurysm surgery by improving proximal artery control and operative fields. This endovascular technique enhances surgical success for challenging cerebral aneurysms.
Area of Science:
- Neurosurgery
- Endovascular Surgery
- Cerebrovascular Disease
Background:
- Surgical treatment of basilar trunk aneurysms presents significant technical challenges.
- Achieving proximal artery control and adequate operative fields is difficult in these cases.
Purpose of the Study:
- To describe the experience with temporary balloon occlusion and intraoperative digital subtraction angiography for basilar trunk aneurysms.
- To evaluate the safety and efficacy of this combined endovascular and surgical approach.
Main Methods:
- Five patients with basilar trunk aneurysms underwent surgery using temporary balloon occlusion.
- A silicone balloon catheter was used for temporary occlusion of the basilar artery proximal to the aneurysm.
- Intraoperative digital subtraction angiography confirmed aneurysm clip placement.
Main Results:
- Temporary balloon occlusion, with a mean duration of 22 minutes, facilitated aneurysm dissection.
- No postoperative deficits were attributed to the temporary occlusion.
- Intraoperative digital subtraction angiography confirmed successful clip placement without complications like distal embolism.
Conclusions:
- Intraoperative endovascular techniques, including temporary balloon occlusion, can improve outcomes for complex cerebral aneurysms.
- This method is particularly beneficial for basilar trunk aneurysms where proximal vascular control is challenging.
