To evaluate long-term effects of arterial embolization (AE) for postpartum hemorrhage (PPH) on menses recovery and subsequent pregnancies. One hundred thirteen consecutive patients, recruited from 1999 to 2006, who had undergone AE for severe PPH were evaluated in a retrospective monocentric study. As embolization agents, pledgets of absorbable gelatine sponge (Curaspon) were used in 106 cases, Curaspon powder in 3 cases, and inert microparticles in 4 cases. In 111/113 cases (98.1%), AE was successful in controlling PPH. In two cases (1.7%), the AE was unsuccessful and required a total abdominal postembolization hysterectomy. Concerning fertility, 6 patients were lost to follow-up and 107 were available. The average time to follow-up was 46.4+/-21.8 months. Of the 107 patients, 99 had recovery of menses (92.5%). Of the 107 (61%) patients, 66 reported regular menstruation with normal delay after the delivery. Thirty-three patients (31%) reported subjective changes in the frequency and amount of menses. Six patients (5.6%) had documented amenorrhea after AE and developed diffuse uterine synechiae at the hysteroscopic investigation. Out of 29 patients who desired and attempted conception, 18 patients (62%) reported a total of 19 pregnancies at the end of the follow-up. One miscarriage at 12 weeks of gestation was reported. The 18 pregnancies at term were uneventful until delivery, but 3 cases of further PPH (15%) occurred due to abnormal placentation requiring a further AE. All full-term newborns were healthy. AE is a feasible, safe, and reproducible technique to control PPH, allowing a very high resumption of menses and subsequent pregnancies; in these cases, considering the elevated incidence of further PPH due to abnormal placentation, an accurate ultrasonographic monitoring during pregnancy seems appropriate.
