Abstract:
BACKGROUND AND AIMS:Until now, no study has focused exclusively on low-flow retrobulbar intraconal venous malformations (RIVMs) which may require treatment due to cosmetic defect, pain, and visual dysfunction. The treatment for RIVMs which surround the optic nerve remains challenging. This case series aimed to evaluate the technical feasibility, effectiveness, and safety of percutaneous sclerotherapy with polidocanol for low-flow RIVMs, using local anesthesia. METHOD:This is a prospective, non-comparative, single-center, interventional case series. All patients signed informed consent forms. Seven patients with RIVMs were treated with percutaneous sclerotherapy with polidocanol/air foam using CT guidance. Primary endpoints are reduction in the volume of RIVMs and pain relief assessed by visual analog scale (VAS). Secondary endpoints are exophthalmos and recording adverse events obtained in clinical follow-up during outpatient visits. RESULTS:Results revealed that the mean volume of RIVMs was decreased from 12.05 ± 6.35 cm3 preoperatively to 1.56 ± 0.43 cm3 postoperatively, (p = 0.005), with a mean decrease of 87.05%. The intraocular pressure was decreased from 14.19 ± 2.99 to 11.79 ± 1.25 mmHg, (p = 0.043). The mean VAS score was decreased from 3.43 ± 2.37 preoperatively to 1.29 ± 0.76 postoperatively, (p = 0.023). The exophthalmos score was decreased from 1.75 ± 0.27 to 1.34 ± 0.31 cm, (p = 0.005). All patients were satisfied with the treatment, which did not leave a postoperative scar. CONCLUSIONS:The results of percutaneous intralesion injection of polidocanol for RIVMs are encouraging. The present results suggest that this method could be a safe and effective treatment option for patients with RIVMs.
