Orbital Venous Malformations

Abstract

To evaluate the clinical, radiological, and histopathological features, treatment, and outcome of a series of orbital venous flow malformations (OVMs) with the aim of delineating a more systematic approach for treatment.Methods: A 38-year retrospective review of 22 patients with OVMs followed up at 1 institute.Results: Eighteen of 22 patients (13 women and 9 men) showed clinical or radiological evidence of distensibility. The mean age at the initial manifestation was 28.3 and 50.7 years in patients with distensible and nondistensible OVMs, respectively. Eight patients (36.3%) had deep orbital lesions, 6 (27.3%) had superficial orbital lesions, and 8 (36.3%) had combined orbital lesions. All 3 patients with deep nondistensible OVMs had a sudden onset of proptosis and pain or diplopia secondary to thrombosis or hemorrhage. Seventeen patients required

Intraorbital arteriovenous fistula with thrombosed varix: Diagnosis and treatment without catheter angiography in a developing country

“…[3] They are usually only treated if symptomatic (either due to mass effect or thrombosis/hemorrhage). Symptomatic AVF in association with thrombosed varices are only amenable to surgical excision under direct vision[1] and the outcomes are usually satisfactory and associated with minimal morbidity. If thrombosed, the anterior part of the varix can usually be relatively easily excised surgically.…”

“…However, symptomatic AVF in association with thrombosed varices are only amenable to surgical excision under direct vision. [1] We describe clinical and radiological findings in a patient with spontaneous onset purely intraorbital AVF with thrombosed varicose superior ophthalmic vein (SOV), which was treated by direct surgical excision and discuss the management strategy.…”

Bilateral Atypical Eyelid Lesions in a 50-Year-Old Woman

“…Sclerotherapy (choice A) is not the recommended next step because it is typically used for the treatment of orbital low-flow lymphovenous malformations, but it has not been studied for use in varicosities of the peripheral arcade . Moreover, sclerotherapy of orbital or facial lesions carries the risk of hemorrhage or embolic events in some cases .…”

Orbital Venous Malformation Accompanied by Arteriovenous Fistula

“…Orbital venous malformation (OVM) is a hemodynamically low-flow vascular malformation caused by aberrant angiogenesis in the embryonic developmental stage [ 1 2 ]. It is a rare disease which accounts for 0% to 1.3% of orbital tumors, and it is usually managed conservatively [ 1 3 ].…”

“…It is a rare disease which accounts for 0% to 1.3% of orbital tumors, and it is usually managed conservatively [ 1 3 ]. However, when OVM is accompanied by acute thrombosis and hemorrhage or when it shows gradual enlargement, the lesion is surgically managed, as it causes intolerable pain, functional impairment, and cosmetic deficits [ 2 4 ]. Herein, we report a case of OVM fed from an arteriovenous fistula in a patient with acute proptosis and vision loss.…”
