Telescoping Pipeline Embolization Devices (PEDs) offers enhanced coverage for intracranial aneurysms but presents technical challenges. This technique, while effective in many cases, is associated with a higher complication rate requiring careful consideration.
Area of Science:
- Neurosurgery
- Interventional Neuroradiology
- Medical Device Technology
Background:
- Telescoping multiple Pipeline Embolization Devices (PEDs) enhances treatment for intracranial aneurysms.
- This technique allows for improved vessel coverage and flexible device placement.
Purpose of the Study:
- To evaluate the technical aspects and challenges of using telescoping PEDs.
- To assess outcomes and complications associated with this advanced neurovascular technique.
Main Methods:
- Retrospective analysis of 46 patients with 48 intracranial aneurysms treated with multiple PEDs across three centers.
- Data collected included patient/aneurysm characteristics, occlusion rates, functional outcomes (mRS), and complications.
Main Results:
- 16 patients (33%) underwent planned telescoping PED placement.
- Complete occlusion was achieved in 70% of aneurysms; 4% required retreatment.
- A higher-than-expected complication rate (4%) was observed, linked to technical complexity.
Conclusions:
- Telescoping PEDs is a valuable technique for complex intracranial aneurysms.
- The procedure's complexity necessitates careful management to mitigate potential complications.
