Abstract

AIM: The aim of this study was to elucidate whether the presence of an ovarian endometrioma is associated with impaired vascular flow. We investigated changes in vascular flow on the ipsilateral and contralateral side of the endometrioma, before and after surgery. METHODS: This prospective case-control study included 144 women (ovarian endometrioma [n = 40], endometriosis without ovarian endometrioma [n = 33], non-endometriotic ovarian cyst [n = 17], and normal pelvis [n = 54]). The uterine artery (UtA) vascular resistance indices (pulsatility index [PI] and resistance index [RI]) were measured using transvaginal Doppler sonography, and UtA diameters were measured using magnetic resonance imaging. RESULTS: The UtA PI and RI were significantly higher on the ipsilateral side of the endometrioma than on the contralateral unaffected side in the endometrioma group (P < 0.01), as well as in the non-endometriotic ovarian cyst group (P < 0.05), and normal pelvis group (P < 0.01). The UtA PI and RI on the ipsilateral side of the endometrioma were significantly lower after cystectomy than before cystectomy (P < 0.01). The UtA diameters were significantly larger (P < 0.01) on the ipsilateral side of the endometrioma than on the contralateral side. CONCLUSION: The UtA-vascular resistance might be higher on the ipsilateral side of the endometrioma than on the contralateral unaffected side, indicating a risk of subclinical atherosclerosis in women with endometriosis.
