OBJECTIVE:

To evaluate the advantages of performing and not performing "Hypogastric artery ligation prior to delivery or modified hysterectomy" in the surgical management of anomalous placental insertion.

MATERIALS AND METHODS:

A retrospective, cross-sectional, comparative, retrospective case series study conducted at the Unidad Médica de Alta Especialidad, Hospital de Ginecoobstetricia 4 Luis Castelazo Ayala, from 2013 to 2019. Inclusion criteria: patients with abnormal placental insertion who underwent hypogastric artery ligation before delivery or before modified obstetric hysterectomy, compared with those who did not have hypogastric artery ligation. Exclusion criteria: patients who did not terminate the pregnancy in the hospital or the information in the file was incomplete. Study parameters: transoperative bleeding, blood transfusion, postoperative morbidity and admission to intensive care. Outcomes were analyzed with descriptive and inferential statistics.

RESULTS:

285 patients were evaluated; 57% (n = 164) with placenta previa, 27% (n = 78) marginal and 15% (n = 43) normoinsert. The placenta accreta spectrum was found in 34% (n = 91) of the sample. In the placenta previa group, the application of the technique decreased transoperative bleeding (p = 0.005) and blood transfusion (p = 0.05). In patients with placenta accreta spectrum there was a reduction of transoperative bleeding (p < 0.01), lower blood transfusion (p = 0.01), intensive care admission (p < 0.001) and days of intensive care stay (p = 0.0001).

CONCLUSIONS:

Hypogastric artery ligation before delivery and before modified hysterectomy in the surgical treatment of anomalous placental insertion showed maximum benefit in the placenta previa and spectrum of placenta accreta groups.
