AI Article Synopsis
- The treatment of brain arteriovenous malformation (bAVM) includes various methods like microsurgery and embolization, with complete obliteration rates that vary significantly based on the grade of the bAVM.
- The study emphasizes the effectiveness of dynamic 3D roadmap technology during endovascular procedures, improving navigation of microcatheters and reducing the need for multiple 2D angiograms, which can lower radiation exposure.
- No complications were reported in the 21 cases treated using this method, highlighting its safety and efficacy in achieving higher rates of complete obliteration during bAVM embolization.
Article Abstract
Purpose: Treatment of brain arteriovenous malformation (bAVM) includes microsurgical excision, stereotactic radiosurgery, endovascular embolization, or combination. With bAVM embolization, complete angiographic obliteration ranges from 12.5 to 51%, and higher total occlusion rate is seen in SM grades I to III, ranging from 96 to 100%.
Methods: In this paper, we illustrate the use of 3D rotational angiography and dynamic (live) 3D roadmap functions in endovascular treatment of bAVM. A single dynamic 3D roadmap or two dynamic 3D roadmaps obtained help tremendously in navigation of microcatheters and wires along the parent artery and bAVM feeders.
Results: This method eliminates the need for repeated 2D angiograms and roadmaps for new working projections every time the C-arm position is changed for cannulation of different feeders, thereby reducing radiation dose. No instances of misalignment error, vascular perforation, or thromboembolic phenomena were observed in the 21 embolization cases performed within the previous 2 years while utilizing this feature.
Conclusion: The dynamic 3D roadmap is an extremely useful tool for multiple-feeder cannulation, by reducing the use of multiple 2D angiograms, providing intraprocedural live and adjustable 3D roadmap for better mental orientation to angioarchitecture of the bAVM, which further aids in the overall complete angiographic obliteration rate of bAVM in a single session especially in multiplug embolization technique.
