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. We followed 50 symptomatic premenopausal women with uterine leiomyomas who underwent uterine artery embolization. We examined 179 leiomyomas among these patients. Magnetic resonance imaging was performed one month before and six months after uterine artery embolization. Two radiologists who specialized in abdominal imaging independently interpreted the images. Main Outcome Measures: The magnetic resonance imaging parameters were the uterus and leiomyomas volumes, their localizations, contrast perfusion pattern and node-to-muscle ratio. RESULTS: Six months after treatment, the average uterine volume reduction was 38.91%, and the leiomyomas were reduced by 55.23%. When the leiomyomas were submucosal and/or had a higher node-to-muscle ratio in the T2 images, the volume reduction was even greater (greater than 50%). Other parameters showed no association. CONCLUSIONS: We conclude that symptomatic uterine leiomyomas in patients undergoing uterine artery embolization exhibit volume reductions greater than 50% by magnetic resonance imaging when the leiomyomas are submucosal and/or had a high node-to-muscle ratio in the T2 images.
- Dissecção espontânea do tronco celíaco: qual a melhor abordagem terapêutica?(2013) GALASTRI, Francisco Leonardo; NASSER, Felipe; AFFONSO, Breno Boueri; AMORIM, Jorge Eduardo de; TRAVASSOS, Fabiellen BerzoiniSpontaneous dissection of visceral arteries is a quite rare event. Sudden abdominal pain in the epigastrium is the most frequent symptom. Advances in imaging techniques have made it easier to establish the diagnosis of this event, increasing the incidence of dissections of visceral arteries. Conservative medical treatment, surgical revascularization, and endovascular therapy are the three treatment options available. We report two cases of patients with spontaneous dissection of the celiac trunk that received different treatments based on clinical presentation and imaging studies. We also conducted a literature review on this disease.
- Safety, efficacy, and prognostic factors in endovascular treatment of pelvic congestion syndrome(2014) NASSER, Felipe; CAVALCANTE, Rafael N.; AFFONSO, Breno B.; MESSINA, Marcos L.; CARNEVALE, Francisco C.; GREGORIO, Miguel A. deObjective: To evaluate the safety and effectiveness of transcatheter embolization using coils for treatment of pelvic congestion syndrome (PCS) and to elucidate prognostic factors for clinical success. Methods: Data were retrospectively analyzed from 113 women with PCS who underwent endovascular embolization of ovarian and pelvic varicose veins at Hospital Clinic Universitario, Zaragoza, Spain between January 2001 and January 2011. Pain score was evaluated before and after the procedure via a visual analog scale (VAS). Associated symptoms (dysmenorrhea, dyspareunia, urinary urgency, and lower limb symptoms) were also evaluated. Patients were followed up for 12 months. Results: The technical and clinical success was 100%. At 12 months, 53% of patients had no pelvic pain and 47% reported a reduction in pelvic pain. The average VAS was 7.34 before the procedure and 0.47 at 12 months. Complete relief of pain and associated symptoms was achieved for 37% of patients. Urinary urgency, lower limb symptoms, and vulvar and lower limbs varicosities were prognostic factors related to incomplete treatment success. The global complication rate was low (5/113,4.4%). Conclusion: Transcatheter embolization was a safe and effective treatment for PCS. Lower limb symptoms, urinary urgency, and varicosities were associated with incomplete clinical success.
