Ruptured Ovarian Artery Pseudoaneurysm in a Postmenopausal Patient Treated with Transcatheter Embolization

Abstract

Ovarian artery pseudoaneurysms are relatively rare entities, usually associated with pregnancy or the early postpregnancy period. Occurrence in older females is even less common. We present a case of ruptured ovarian artery pseudoaneurysm in an older postmenopausal patient, successfully treated with transcatheter embolization.

Peripartum hemorrhage: Two cases of ruptured ovarian artery aneurysms with additional multifocal intact aneurysms

“…[ 5 ] These additional factors likely explain why the majority of OAA ruptures are reported in multiparous women. [ 1 - 4 ] Further, the first patient in this case series were found to have diminutive uterine arteries [ Figure 3 ] while the second patient was found to have a congenitally absent right uterine artery and diminutive left ovarian artery [ Figure 6g ]. This suggests that the pregnancies were preferentially supported by the ovarian arteries which would necessarily hypertrophy and be subject to increased flow.…”

“…Ovarian artery aneurysms are rare and often asymptomatic until stress such as trauma, increased pressure, or a change in flow dynamics cause rupture and consequentially rapid clinical decline. [ 1 - 3 ] The underlying mechanism of OAA formation is not clear, but a major risk factor appears to be multiparity. As a rare condition, it is unknown if vasculitis or connective tissue disorders predispose patients to OAA, though it would be prudent to monitor those patients closely should they become pregnant.…”

“…Although first described in 1963, ovarian artery aneurysm (OAA) ruptures are rare with less than 30 reported cases in the literature. [ 1 - 3 ] Multigravida and the physiologic changes of pregnancy are thought to be major risk factors for OAA development, with most cases occurring near the intrapartum period. [ 1 - 5 ] Herein, two cases of OAA are presented.…”

Spontaneous Rupture of Ovarian Artery Aneurysm in a Postmenopausal Woman: A Case Report and Literature Review

“…Based on a MEDLINE search of the English language literature from 1995 to 2020, only 9 cases of spontaneous rupture of an ovarian artery aneurysm not related directly to pregnancy have been published ( Table 1 ) [ 5 6 7 8 9 10 11 12 13 ]. The ages of the patients ranged from 35 to 69 years (mean, 51.2 years), and 5 of 9 patients were postmenopausal.…”
