Direct puncture and sclerotherapy with sotradecol ((r)) . Orbital lymphatic malformations

We evaluated sclerotherapy in the treatment of orbital lymphatic malformations. Six consecutive patients with unilateral orbital cystic masses and recurrent episodes of orbital swelling were included in this retrospective study. All have been treated with percutaneous puncture and injection of Sotradecol (sodium tetredecyl sulphate) under radiographic guidance, on one or more occasions. Reduction of orbital mass volume was documented clinically and radiologically within a few weeks in all cases. There was total regression of proptosis in three instances. There were no immediate complications. One subject suffered a presumably coincidental orbital hemorrhage two weeks after treatment. Follow-up times ranged between six months and four years. Sotradecol sclerotherapy appears to be a useful adjunct to the therapeutic arsenal for orbitallymphatic malformations.
