AbstractThe treatment of orbital lymphaticovenous malformations (OLVMs) has evolved from simple surgical resection to a multimodal approach consisting of sclerosing agents, embolization, and resection depending on the specific components that compose the lesion. Here we present a representative case series of 5 nonconsecutive patients who underwent percutaneous embolization of OLVMs with the Onyx Liquid Embolic System (Medtronic, Dublin, Ireland) before surgical resection between 2019 and 2021. OLVMs are rare, benign, congenital lesions that grow with age and can become symptomatic and disabling. Treatment can be conservative or invasive; depending on the clinical presentation and characteristics of the lesions, treatment modalities can vary. Preoperative percutaneous embolization of OLVMs with the Onyx system is a promising technique, as demonstrated in this case series.Copyright © 2021 Elsevier Inc. All rights reserved.
