Insights
Medically refractory vertebral artery dissection can be treated with endovascular coil occlusion. A single long oversized coil offers a safe, rapid, and cost-effective alternative for vessel sacrifice in these cases.
Area of Science:
- Vascular Surgery
- Interventional Neurology
- Endovascular Therapy
Background:
- Vertebral artery dissection (VAD) is a significant cause of stroke.
- Medical management is the primary treatment, but some cases are medically refractory.
- Endovascular techniques, including parent vessel occlusion, are options for refractory VAD.
Observation:
- Two cases of medically refractory symptomatic VAD were treated.
- Successful vessel coil occlusion was achieved using a single long oversized coil in both patients.
- This technique for vessel sacrifice has not been previously described.
Findings:
- No periprocedural complications occurred.
- Both patients experienced excellent clinical and angiographic outcomes.
- Patients remained asymptomatic during follow-up.
Implications:
- A single long oversized coil is a safe, rapid, and cost-effective endovascular option for vessel sacrifice in refractory VAD.
- This method may offer an alternative to existing techniques for managing complex vertebral artery dissections.
- Further research could validate this approach for broader clinical application.
Abstract:
Vertebral artery dissection may lead to stroke. Medical therapy is usually the first line of treatment. The endovascular approach of medically refractory vertebral artery dissection may include numerous techniques, including coil occlusion of the parent vessel. Two cases are presented of medically refractory symptomatic vertebral artery dissections in which vessel coil occlusion was successfully achieved with a single long oversized coil. There were no periprocedural complications and both patients had excellent clinical and angiographic outcome and remained asymptomatic on follow-up. The use of a single long oversized coil in vessel sacrifice has not been described previously. It represents a safe, rapid and cost effective alternative to the current existing techniques for vessel sacrifice.
