Contrast-enhanced ultrasound (CEUS) is a cost-effective, quick, and non-invasive imaging modality that has yet to be incorporated in uterine artery embolization (UAE). We present two cases that demonstrate the utility of CEUS in UAE for the identification of uterine-ovarian collaterals which otherwise can result in ineffective fibroid treatment and non-target embolization.

Objective The current study aimed to investigate the application of contrast-enhanced ultrasound (CEUS) in diagnosis and treatment of cesarean scar pregnancy (CSP). Methods A retrospective study was performed in 35 patients with clinically suspected CSP who requested termination of pregnancy and underwent contrast-enhanced ultrasound (CEUS). The patients were classified into two groups on the basis of whether they received uterine artery embolization (UAE). The CEUS characteristics of the two groups were reviewed. Results CEUS features of CSP were early enhancement of the cesarean scar and continuous infusion of contrast agent between the gestational sac and cesarean scar. Myometrial thickness in the cesarean scar was thinner in the UAE group than in the non-UAE group by CEUS and transvaginal ultrasound. Myometrial thickness measured by CEUS was thinner than that measured by transvaginal ultrasound in both groups. The parameters of the time-intensity curve in the UAE group were characterized by a faster arrival time, shorter time to peak, higher peak intensity, and greater enhancement rate compared with the non-UAE group. Conclusions CEUS may be a novel supplementary method to diagnose and assess CSP, and to help evaluate whether UAE is required.

Background In order to achieve sustained symptom control and minimize the risk of recurrence, uterine artery embolization (UAE) should aim at complete infarction of all fibroids. Purpose To retrospectively evaluate the infarction rate of uterine fibroids in patients that had undergone uterine artery embolization (UAE) after the introduction of contrast-enhanced ultrasound (CEUS) during UAE procedures at our institution. Material and Methods Thirty patients treated with UAE between February 2006 and August 2009 were included. MR images obtained before, at 3 months, and 12 months after the procedure were reviewed. We evaluated volume changes in dominant fibroids as well as the infarction rate of all fibroids in each patient. Clinical results were evaluated by reviewing the medical records. The study was approved by the institutional review board. Results CEUS was technically successfully performed during the UAE procedure in all patients. In five cases the endpoint of embolization was adjusted based on findings at CEUS. The mean volume shrinkage of dominant fibroids was 39.8% after 3 months and 59.8% after 12 months. There was complete infarction of all fibroid tissue in 97% of patients at 3 months and 96% at 12 months. No major complications were observed. Conclusion After the introduction of CEUS during UAE procedures in our institution, high infarction rates were achieved.

Abstract. Conventional ultrasound is worldwide the first-line imaging modality for the prompt diagnosis in the daily practice because it is a cost-effective and easy to perform technique. The additional application of contrast media has been used to enhance the intravascular contrast and to improve the imaging diagnostic accuracy in the detection, classification and follow-up of vascular pathologies. Contrast-enhanced ultrasound has the advantage of being a safe, fast and dynamic non-invasive imaging tool with excellent results in the diagnosis of acute aortic pathologies, especially the detection of endoleaks after endovascular aneurysm repair. This review describes the diagnostic and therapeutic roles of ultrasound and contrast-enhanced ultrasound imaging in the most common vascular pathologies such as aortic dissections, aneurysms and endoleaks. Keywords: Endoleak, contrast media, ultrasonography, aorta
