Intraorbital arteriovenous malformation treated by transarterial embolization: technical case report

Neurosurgery. 2011 Jun;68(2 Suppl Operative):383-7; discussion 387. doi: 10.1227/NEU.0b013e31821522ec.


Background and importance: Intraorbital arteriovenous malformations (AVMs) are rare, and their clinical management is controversial. A case of orbital AVM successfully treated by transarterial embolization with diluted glue is reported.

Clinical presentation: A 53-year-old man developed a left pulsating exophthalmos, chemosis, and ocular pain, revealing the presence of a left intraorbital AVM. A microcatheter was selectively placed into the feeders arising from the left ophthalmic artery. Diluted glue was injected toward the nidus through the microcatheter, with monitoring by digital subtraction angiogram. These procedures were performed for 2 individual proper feeders. Superselective angiography for the central retinal artery was also performed instead of a retinal Wada test. His orbital symptoms improved immediately after the procedure without further visual disturbance. Follow-up digital subtraction angiogram revealed the disappearance of the AVM.

Conclusion: Transarterial embolization can be considered one of the radical treatments for orbital AVMs.
