IntroductionHaemorrhages from the genital tract remain a major threat to the life of patients with advanced cervical cancer. It is possible to achieve haemostasis by both surgical techniques and the procedure of endovascular uterine artery embolization. However, in some women with loco-regionally advanced cervical cancer the obliteration of the uterine arteries is not effective.AimEvaluation of morphological changes in uterine arteries in patients with advanced cervical cancer and comparison of their changes with the achieved haemostatic effect of obliteration.Material and methodsThe prospective study included a group of 8 women with cervical cancer at a clinical stage of IIB to IIIC according to the FIGO classification. 3D quantitative coronary angiography (QCA) was performed before uterine embolization. The haemostatic effect of uterine artery embolization was compared with observed vascular changes.ResultsMean uterine artery length in patients who achieved complete hemostasis: 39.5 mm – right uterine artery; 38.7 mm – left uterine artery. Mean uterine artery length in patients who achieved partial satisfactory haemostasis: 32 mm – right uterine artery; 30.5 mm – left uterine artery. Mean uterine artery length in patients who achieved unsatisfactory haemostasis: 10.5 mm – right uterine artery; 19 mm – left uterine artery.ConclusionsShortening of uterine arteries worsens prognosis of the haemostatic effect of their obliteration in patients with advanced cervical cancer.
