Sclerotherapy as an alternative treatment for complex, refractory seromas

Traditional therapy for seromas often entails compression, aspiration, drainage, or surgical excision and re-closure; however, more complex, treatment-refractory seromas may require additional treatment. Sclerotherapy has been well documented in the treatment of simple pleural effusions, vascular malformations, lymphoceles and seromas. However, little evidence is available on the efficacy of sclerotherapy in complex, treatment-refractory seromas that develop post-operatively in patients with complex medical histories. We present a case series highlighting the use of sclerotherapy by interventional radiology as an alternative or adjunctive treatment method for chronic, high-volume post-operative seromas recalcitrant to multiple attempts of traditional treatment. At long-term follow-up, the seromas resolved after a maximum of four rounds of sclerotherapy with various combinations of known sclerosants. Highly complex cases of large, chronic seromas may be refractory to conservative modalities and re-closure. Sclerotherapy can be considered an alternative method or adjunctive treatment for chronic, recalcitrant post-operative seromas.
