Foam sclerotherapy : the Maltese experience

Abstract

Objectives: To describe demographics and outcomes of a new sclerotherapy service – Foam sclerotherapy (FS), for venous disease at Mater Dei Hospital, Malta Methods: The data of a consecutive series of patients undergoing FS were prospectively entered into a database and the results analysed. Medical notes of patients were also reviewed. Patients underwent detailed venous duplex scanning before and after each intervention and at follow-up visits. Results: 121 patients underwent a total of 204 FS procedures between November 2008 and October 2011. 22% were male and 78% of the procedures were done in female patients. 151 (74%) of procedures were done in patients above the age of 50 years. 74(37%) interventions were for recurrent varicose veins and 113(55%) for chronic venous insufficiency (CEAP4-6). 77 (38%) patients had active or healed venous ulceration as the indication for treatment. 83% of ulcers healed after foam sclerotherapy during the follow up period. 88.3% (143/162) of veins treated were completely occluded while 11.7% (19/162) were partially occluded. In the majority (64%) only one treatment session was required. One patient sustained an anaphylactic reaction to the sclerosant. No deep vein thromboses, cardiovascular events, pulmonary embolism or other major complications were reported. Skin staining was reported in 21.5% of cases. Conclusions: Foam sclerotherapy is a safe and cheap treatment modality resulting in high rates of venous ulcer healing and successful venous occlusion and a very low complication rate. The success rate of foam sclerotherapy in Malta is comparable to that reported in the literature.
