Abstract
PURPOSE: To describe a hybrid procedure for orbital venous malformation in the endovascular operating room (EVOR). METHODS: Five consecutive patients with venous malformation in the periocular and orbital region were included. All patients received a one-stage direct puncture venogram, image-guided glue injection, and surgical resection in the EVOR equipped with a biplane digital subtraction angiography system (BDSAS). RESULTS: The mean age at the time of operation was 37.4 years (range, 22-69 years). The mean operative time was 193 min (range, 138-324 min). No intraoperative complications were noted. The mean follow-up duration was 18.8 months (range, 10-24 months). Three patients had complete removal of the vascular lesions. At the latest follow-up, no recurrence of symptoms related to the lesions was noted. All patients had an uneventful recovery and satisfactory outcome. CONCLUSIONS: The hybrid procedure of orbital venous malformation in the EVOR is a novel application in ophthalmology. It is a safe and well-controlled procedure with real-time high-quality BDSAS surveillance to facilitate surgical resection. Its success requires collaboration between the interventional radiologist, the surgeon, and the ophthalmologist.
