The safety and effectiveness of preserving the ascending uterine artery in a modified fertility-sparing abdominal radical trachelectomy

To evaluate the outcome of preserving the ascending uterine artery in a modified fertility-sparing abdominal radical trachelectomy and understand whether preserving uterine arteries during abdominal radical trachelectomy is helpful for patients. From September 2005 to September 2019, 31 early uterine cervical cancer patients who underwent modified fertility-sparing abdominal radical trachelectomy were enrolled in this study, and were followed up in our cancer center. Computed tomography (CT) of the abdomen and pelvis was advised as the initial investigation to evaluate the ascending uterine artery in 11 patients. The major outcomes were recurrence, mortality, CT results and obstetric outcomes. During the median follow-up of 56 months, two recurrences were recorded. Among 11 patients who underwent CT, none of them showed uterine arteries occlusion. Fifteen patients attempted to conceive, and 5 pregnancies were achieved in 5 patients. Hence, the pregnancy rate among patients who attempted to conceive was 33.3 %. There was only one artificial first-trimester abortion. Three pregnancies resulted in live births, and two of them got full-term births. The modified fertility-sparing abdominal radical trachelectomy in preserving uterine arteries is effective, and it is recommended that surgeon should retain the uterine artery as much as possible during operation.
