Abstract
ObjectiveTo guarantee a better perfusion, the preservation of the uterine arteries during ART has sometimes been performed but has seldom been tested. We share the results of our tests to provoke a potentially different point of view on such uses of ART. MethodsUsing computed tomography angiography (CTA), we identified the uterine blood supply in patients who underwent ART with uterine artery preserved and sacrificed. ResultsWe included 26 consecutive post-ART patients from the outpatient service. The uterine arteries were preserved in 16 patients (61.5%) and ligated in 10 patients (38.5%). Out of the 26 patients studied, 17 (65.4%) were supplied by only the ovarian arteries; seven (26.9%) by one uterine artery and the contralateral ovarian artery; and only 2 (7.6%) by the uterine artery supply alone. No recanalization of the ligated uterine artery or other newly formed compensatory circulation was observed. Among the 16 patients who had preserved uterine arteries, only two (12.5%) showed identifiable bilateral uterine arteries, whereas seven (43.6%) had unilateral uterine artery occlusion and another seven (43.6%), bilateral occlusion. We had three obstetric outcomes, two of which came from the ovarian artery supplying group and one from the hybrid supplying group. ConclusionsThe ovarian artery became the dominant supplying vessel after ART. The anatomically preserved uterine artery had an 87.5% chance of occlusion after the procedure. Moreover, the contributing uterine artery did not show any functional superiority. Thus, the benefit of preserving the uterine arteries during ART is probably very limited.
