Is endovascular treatment of the great saphenous vein (with immediate foam sclerotherapy of superficial tributary veins) in an outpatient clinic really safe and profitable?

ABSTRACT

BACKGROUND: This preliminary study aimed to evaluate the safety of radiofrequency (RF) thermoablation of the great saphenous vein (GSV) with immediate foam sclerotherapy of superficial tributary veins performed in the outpatient clinic (Hospital Department). Further, we also evaluated the cost reduction compared to the same procedure performed in the operating room. METHODS: Thirty patients were evaluated for RF thermoablation of the GSV. Foam sclerotherapy was performed with 1-3%sodium-tetra-decyl-sulphatefoam (Tessari’s method). We evaluated the possible risks of the procedure and methods to resolve them. We compared the costs of both procedures performed in the operating room and in the outpatient clinic. RESULTS: We had complete occlusion of the GSV in 28/30 patients (93.3%). Periodic check-up revealed a reflux through an anterior lateral saphenous vein in one patient and a long saphenous stump in another patient. There were no severe intraoperative complications. In two cases, it was necessary to convert the radiofrequency procedure into foam sclerotherapy (using the hollow probe as a long catheter in one case and using needle injection in the second case). In another case, it was necessary to perform surgical cannulation of the GSV. There were no severe postoperative complications. Moreover, the cost of the operating room procedure was € 1226.50, while that of the outpatient clinic procedure was € 1082.65 (cost reduction, 12.5%). CONCLUSIONS: This procedure is safe and sufficiently cost-effective to perform in an outpatient clinic and the operating room can hence be reserved for patients with more serious pathologies. These results should be validated in further studies with larger sample size.
