This retrospective teaching-hospital study evaluated 18 patients with ovarian endometrioma ≥3 cm and preprocedural AMH <2 ng/mL to assess the therapeutic efficacy of catheter-directed ethanol sclerotherapy (CDS) and its impact on ovarian reserve. Using an 8.5-F catheter placed transabdominally or transvaginally into the cyst, aspiration was followed by 99% ethanol with 20-minute retention, with outcomes assessed by ultrasound and serum AMH/CA-125 and dysmenorrhea visual analog scale at baseline and 6 months. At 6 months, cyst size and CA-125 levels decreased significantly, dysmenorrhea scores improved in all patients, but AMH did not change significantly (p = .875). The main limitation is its small sample size and retrospective design, restricting the strength of inferences about ovarian reserve effects. This paper is centrally about endometriosis — specifically, catheter-directed ethanol sclerotherapy for ovarian endometrioma and its effect on ovarian reserve in patients at risk of decreased AMH.

Abstract

STUDY OBJECTIVE: To investigate the therapeutic efficacy of catheter-directed ethanol sclerotherapy (CDS) and its effect on ovarian reserve in patients with endometrioma at risk of decreased ovarian reserve. DESIGN: Retrospective study. SETTING: Teaching hospital. PATIENTS: We evaluated 18 patients with ovarian endometrioma measuring ≥3 cm and preprocedural serum antimüllerian hormone (AMH) levels of <2 ng/mL. INTERVENTIONS: An 8.5-F catheter was inserted either transabdominally or transvaginally into the endometrioma. After aspiration, sclerotherapy with 99% ethanol was performed, with a subsequent 20-minute ethanol retention. MEASUREMENTS AND MAIN RESULTS: Ultrasonography was performed preprocedurally and 6 months after CDS to evaluate any recurrence or changes in cyst size. Furthermore, serum AMH levels, cancer antigen 125 (CA-125) levels, and the visual analog scale scores for dysmenorrhea were obtained to analyze the ovarian reserve and treatment efficacy, preprocedurally and at 6 months after CDS. The mean cyst size on ultrasonography and serum CA-125 levels decreased 6 months after CDS (p <.001 and p = .001, respectively). All patients reported a decreased visual analog scale score for dysmenorrhea (p <.001). However, the difference in serum AMH levels before and after CDS was statistically insignificant (p = .875). CONCLUSION: CDS was efficacious in reducing pain and serum CA-125 levels in patients with low AMH levels without adversely affecting their ovarian reserve.
