title: [Effect of technical and anatomical factors on efficacy of embolization of uterine arteries].
abstract: The article deals with analysis of technical and anatomical factors influencing the efficacy of uterine arteries embolization (UAE) in treatment of patients with uterine myoma. Based on experience gained in 420 interventions, the authors revealed that inefficiency of UAE may be attributed to the following causes: 1) a technical failure associated with anatomical peculiarities of the uterine artery or a spasm thereof; 2) incomplete embolization apparently attributable to both technical and anatomical factors; 3) an adventitious restoration of blood supply to the uterine myoma. We also determined the significance of utero-ovarian arterial anastomoses in blood supply of the myomatous nodes, suggesting technical manipulations making it possible to attain adequate embolization thereof, if such. Technical and anatomical factors play a decisive role in successful outcomes of UAE, which, if failed due to restoration or preservation of blood supply of the myomatous nodes, should be followed by a repeat intervention.
