Ethanol Sclerotherapy in the Management of Ovarian Endometrioma: Technical Considerations for Catheter- and Needle-Directed Sclerotherapy

To provide technical guidance on applying catheter-directed and needle-directed ethanol sclerotherapy for endometriomas and present the results of these sclerotherapy methods. From January 2015 to March 2021, the results of the patients with symptomatic ovarian endometriomas who underwent needle-directed or catheter-directed sclerotherapy were evaluated, retrospectively. The decision to apply which sclerotherapy technique was made during the procedure for each patient considering the following factors: cyst size, cyst location, cyst viscosity, and tissue rigidity. Both needle-directed (n = 34 cysts) and catheter-directed (n = 34 cysts) sclerotherapy techniques were effective, with a 100
