Review of magnetic resonance-guided focused ultrasound in the treatment of uterine fibroids.

Uterine leiomyoma is the most frequently occurring solid pelvic tumor in women during the reproductive period. Magnetic resonance-guided high-intensity focused ultrasound is a promising technique for decreasing menorrhagia and dysmenorrhea in symptomatic women. The aim of this study is to review the role of Magnetic resonance-guided high-intensity focused ultrasound in the treatment of uterine fibroids in symptomatic patients.

Predictive factors for pelvic magnetic resonance in response to arterial embolization of a uterine leiomyoma.

Objective: Minimally invasive methods are used as alternatives to treat leiomyomas and include uterine artery embolization, which has emerged as a safe, effective method. This study aims to evaluate the magnetic resonance imaging predictors for a reduction in leiomyoma volume in patients undergoing uterine artery embolization.

Methods: This prospective longitudinal study was performed at a university hospital.

Endometrium evaluation with high-field (3-Tesla) magnetic resonance imaging in patients submitted to uterine leiomyoma embolization.

Objective: To evaluate the endometrial alterations related to embolization of uterine arteries for the treatment of symptomatic uterine leiomyomatosis (pelvic pain and/or uterine bleeding) by means of high-field (3-Tesla) magnetic resonance.

Methods: This is a longitudinal and prospective study that included 94 patients with a clinical and imaging diagnosis of symptomatic uterine leiomyomatosis, all of them treated by embolization of the uterine arteries. The patients were submitted to evaluations by high-field magnetic resonance of the pelvis before and 6 months after the procedure.

[Uterine fibroid embolization in women with giant fibroids].

Purpose: to evaluate the effectiveness of uterine fibroid embolization (UFE) in patients with giant fibroids, with regard to both clinical outcomes and size reduction.

Methods: twenty-six patients with a mean age of 36.5 years, carrying symptomatic fibroids with a volume over 1,000 cm³, were referred for UFE.

Endovascular surgery in gynecology.

Endovascular surgery has presented a high evolution since 1960 with Charles Dotter, who changed the concept of catheter utilization as a mean to diagnose and introduce therapeutic in interventionist vascular environment. The first reports of bleeding control of gastrointestinal and transluminal angioplasty input the development of new techniques for endovascular access, and new materials use, such as microcatheters and embolic agents, become this procedure effective and viable for treatment of several pathologies. The embolization of several organs of human body is a procedure carried out for more than 30 years all over the world showing safety, efficacy and of simple execution.

[Strategies for reduction of exposure to ionizing radiation in women undergone to uterine fibroid embolization].

Purpose: to determine the dose of ionizing radiation absorbed by the ovaries and the skin of patients undergoing uterine fibroid embolization (UFE), and to suggest a radiologic protocol directed at reducing the risks involved in this procedure.

Methods: seventy-three consecutive women (mean age: 27 years) participating in an institutional research protocol, having symptomatic uterine fibroids with indication for minimally invasive treatment, underwent UFE. We estimated the radiation absorbed by the ovaries by means of vaginal dosimeters and the radiation dose absorbed by the skin by means of indirect calculations of radiation absorption.
