Traumatic arteriovenous fistula treated by superselective embolisation with microcoils: case report
Neuroradiology
|January 1, 1995
Summary
This study presents a successful case of treating a direct dural arteriovenous fistula (DAVF) using microcoil embolization. This minimally invasive technique effectively obliterated the fistula, resolving the patient
Area of Science:
- Neurosurgery
- Interventional Radiology
Background:
- Direct dural arteriovenous fistulas (DAVFs) are abnormal connections between arteries and veins in the dura mater.
- Traumatic DAVFs can arise from head injuries and may present with symptoms like bruits.
Observation:
- A 27-year-old man developed a right temporal bruit following blunt head trauma.
- Angiography confirmed a direct DAVF involving the middle meningeal artery and draining into the cavernous sinus.
Findings:
- Microcoil embolization was successfully performed using a Tracker-18 catheter.
- The procedure achieved complete obliteration of the DAVF, with immediate resolution of the patient's bruit.
Implications:
- Microcoil embolization is a viable and effective treatment for direct DAVFs when a microcatheter can access the draining vein.
- This technique offers a minimally invasive option for managing traumatic dural arteriovenous fistulas.
