Aim of Study:The objective of this study is themanagement of symptomatic slow-flow vascular malformations with foam sclerotherapy. Materials and Methods:Out of 35 patients with vascular malformation intervened ,17 (50%)patients with symptomatic slow flow vascular malformation were prospectively evaluated and subjected to foam sclerotherapy under fluoroscopy and ultrasound guidance. Results:A total of 17 patients were included in the study.Of which 12(71%) were female and 5(29%) were male.82% (14)of patients presented with pain.Among patient who presented with pain 78%(11) had 95% improvement in pain with single session.Out of the 17,30%(5) of patients with previous history of surgery required more number of session for symptom(pain) reduction when compared to patients presented with primary lesion. Conclusion:Foamsclerotherapy can be used successfully to treat slow flow vascular malformation with less complications.In pediatric patients presenting with diffuse lesions,sclerotherapy is the initial viable modality and surgical intervention can be postponed.
