Summary
This study shows that using 0.035-inch coils can effectively treat complex vascular lesions like aneurysms and dural arteriovenous fistulas (DAVFs). This method reduces coil usage and cost while achieving complete occlusion.
Area of Science:
- Interventional Neuroradiology
- Vascular Surgery
- Endovascular Therapy
Background:
- Parent artery occlusion and sinus packing for dural arteriovenous fistulas (DAVFs) can be challenging and costly.
- Traditional methods often require numerous expensive coils for complete occlusion.
Purpose of the Study:
- To evaluate the utility of 0.035-inch coils in endovascular embolization procedures.
- To assess the effectiveness of 0.035-inch coils in reducing coil number and expense for complex vascular lesions.
Main Methods:
- A strategy involving detachable coils for anchoring, fibered coils for stabilization, and 0.035-inch coils for final occlusion was employed.
- Seven consecutive patients with intractable aneurysms, traumatic vessel injuries, or DAVFs were treated using this technique.
Main Results:
- All procedures were safely performed, achieving complete occlusions in all seven patients.
- A mean of 20.1 coils and 258.4 cm total coil length were used per vessel.
- The 0.035-inch coils were used in conjunction with detachable and fibered coils.
Conclusions:
- Endovascular parent artery occlusion and sinus packing with 0.035-inch coils are effective.
- This approach reduces the number and cost of coils required for immediate occlusion.
- The 0.035-inch coils offer a valuable adjunct for complex endovascular embolization cases.
