Percutaneous Sclerotherapy of Congenital Slow-Flow Vascular Malformations of the Orbit

Abstract

Congenital slow-flow vascular malformations of the orbital region are rare lesions that should be treated using a multidisciplinary approach. Monitoring of the intraorbital pressure is required both during and after the procedure to decide about the need for lateral canthotomy to reduce the transiently increased intraorbital pressure.

Sclerotherapy for low-flow vascular malformations of the orbital and periocular regions: Systematic review and meta-analysis

“…This is important especially concerning the known risk of vision loss and orbital compartment syndrome. 6,7 Because of that, we believe it is important to perform orbital sclerotherapy with the support of a multidisciplinary team to ensure an early decompression in the case of compartment syndrome. These findings are important as they provide important information regarding the risks and benefits of percutaneous sclerotherapy for vascular malformations of the orbit and periocular region.…”

Polidocanol monotherapy for a superficial orbital venous malformation in a horse

“…Complications during or following sclerotherapy were not observed in our study. In humans, there is a low complication rate following sclerotherapy as monotherapy of orbital and periocular venous malformations, with reported complications including swelling, discomfort, skin erythema, skin necrosis, scar formation, orbital compartment syndrome, vision loss, reduced infraorbital nerve sensation, 10 and most commonly, the need for repeated treatments for resolution 11 . Adverse effects reflect differences in technique, severity of disease, and sclerosing agents used 12 …”

“…Commonly, a mixture of the sclerosant and contrast agent is used. Application of manual pressure may also be performed to prevent sclerosant from entering a draining vein that may result in non‐target sclerosis 10–12 . There are currently no reports of sclerotherapy, as monotherapy being used to treat an orbital venous malformation in any animal.…”

Sclerotherapy for eyelid and anterior orbital venous-lymphatic malformation

“…Chiramel and colleagues selected ten patients with orbital venous-lymphatic lesions and reported resolution of lesion in all patients by injecting STS in the digital subtraction angiography suite 12 . Hill et al.…”
