Transvenous embolization with flow arrest offers a novel approach for treating complex brainstem arteriovenous malformations (AVMs). This technique aims to improve obliteration rates by temporarily halting blood flow during embolization.
Area of Science:
- Neurology
- Interventional Neuroradiology
- Neurosurgery
Background:
- Brainstem arteriovenous malformations (AVMs) are rare and pose significant surgical challenges due to their location.
- Ruptured brainstem AVMs have a high risk of mortality and rebleeding.
Purpose of the Study:
- To describe a novel transvenous embolization technique for brainstem AVMs.
- To demonstrate the efficacy of simultaneous arterial and venous flow arrest in improving AVM obliteration.
Main Methods:
- A case report detailing the treatment of a ruptured brainstem AVM in a male patient in his 50s.
- Transvenous liquid embolization using Onyx with simultaneous arterial and venous flow arrest via balloon catheters (HyperGlide and Scepter C).
Main Results:
- Successful obliteration of the brainstem AVM was achieved using the described technique.
- The simultaneous flow arrest method facilitated intranidal flow reduction and enhanced nidal occlusion.
Conclusions:
- Transvenous embolization with arterial and venous flow arrest is a promising technique for treating complex brainstem AVMs.
- This approach may offer improved outcomes for challenging AVM cases.
