Abstract

The objective of this study was to develop two new techniques for the conservation of uterine arteries in abdominal radical trachelectomy. Abdominal trachelectomy with conservation of uterine arteries was performed in two patients with cervical carcinoma. In the first case, the internal iliac artery was divided at 2.0 cm from the bifurcation of the common iliac artery. The internal iliac artery and uterine artery were skeletonized along their lengths to the lateral cervix. The dissected internal iliac artery was then reanastomosed following the radical trachelectomy. In the second case, the technique was similar to that of the first except that the internal iliac artery was not divided. Intraoperative observation and postoperative color Doppler ultrasound were used to confirm the patency of the uterine arteries. The operative time of the two patients was 390 min. and 350 min, respectively. Doppler flow studies demonstrated that the uterine arteries were patent in both cases. Resistance index of the left and the right uterine artery was 0.58 and 0.61, respectively, in the first case, and 0.60 and 0.63, respectively, in the second case. Reanastomosis of the internal iliac arteries or skeletonization of the internal iliac arteries are both feasible methods to conserve the uterine arteries during abdominal radical trachelectomy.
