Summary
Flow diversion successfully treated a spinal arteriovenous malformation complicated by a pseudoaneurysm, resolving severe back pain and radiculopathy. This minimally invasive technique offers a potential treatment for spinal artery aneurysms.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Vascular Neurology
Background:
- Spinal arteriovenous malformations (AVMs) can present with severe symptoms like back pain and radiculopathy.
- Pseudoaneurysms (PAs) are a rare but serious complication of spinal AVMs, potentially leading to mass effect.
- Conservative management of spinal AVM complications may yield limited results.
Purpose of the Study:
- To report a case of spinal cord AVM with PA formation treated with flow diversion.
- To evaluate the efficacy and safety of flow diversion for spinal artery aneurysms.
Main Methods:
- Digital subtraction angiography for diagnosis and treatment planning.
- Conservative management initially attempted.
- Selective treatment of the pseudoaneurysm using flow diversion (FD).
Main Results:
- The spinal AVM was complicated by acute feeder dissection and pseudoaneurysm formation causing mass effect.
- Conservative management showed limited angiographic and clinical improvement.
- Flow diversion resulted in pseudoaneurysm occlusion and shrinkage, leading to symptom resolution.
Conclusions:
- Flow diversion is a potentially feasible treatment for spinal artery aneurysms in select patients.
- Favorable patient anatomy is crucial for successful flow diversion treatment.
- The requirement for antiplatelet therapy with current devices is a significant limitation.
