Percutaneous sclerotherapy of para-orbital and orbital venous malformation: A single center, case series

Purpose To present a case series of percutaneous sclerotherapy of para-orbital and orbital venous malformations. Method Seven patients with venous malformations in the orbital and para-orbital region were reviewed. Puncture venogram was performed on all patients and image guided bleomycin injections using biplane digital subtraction in angiography suite. Results Average age of patients at the time of the procedure was 22 years old with the youngest being five years of age and the oldest being 50 years. Follow-ups ranged from 3 months to 18 months and the average follow-up duration was 13 months. The patients had no intraprocedural complications and reported symptomatic relief of pain as per the last follow-up. Patients have shown no symptoms or signs of recurrence of lesions with uneventful recovery so far. Conclusions Percutaneous sclerotherapy of orbital Venous Malformations with bleomycin is a safe and well-controlled procedure done in real time; it has no major systemic adverse side effects and higher efficacy than other sclerosing agents.
