PURPOSE To compare the effectiveness and toxicity of transcatheter arterial chemoembolization (chemoembolization) and yttrium-90-labeled microspheres (radioembolization) in patients with unresectable hepatocellular carcinoma (HCC). MATERIALS AND METHODS Outcomes from patients who underwent radioembolization or chemoembolization as the only treatment for(More)
PURPOSE To compare the clinical effectiveness of retrievable and permanent inferior vena cava (IVC) filters. MATERIALS AND METHODS A retrospective cohort study of consecutive patients who received retrievable or permanent IVC filters from January 2002 through December 2006 was conducted. Patient characteristics and clinical outcomes were compared with(More)
The purpose of this study was to assess the presence and severity of pain levels during 24 h after uterine fibroid embolization (UFE) for symptomatic leiomyomata and compare the effectiveness and adverse effects of morphine patient-controlled analgesia (PCA) versus fentanyl PCA. We carried out a prospective, nonrandomized study of 200 consecutive women who(More)
The liver is the most common visceral site of colorectal cancer metastasis and recurrence. Given that only 25% of patients with colorectal liver metastases are amenable to curative surgical resection at initial diagnosis, locoregional intra-arterial therapies including hepatic arterial infusion chemotherapy, conventional transarterial chemoembolization,(More)
BACKGROUND AND OBJECTIVES Chemoembolization with doxorubicin drug eluting beads (DEB) is a novel locoregional treatment modality for unresectable hepatocellular carcinoma (HCC). Initial animal studies and clinical trials suggest that treatment with DEB may provide safer and more effective short-term outcomes than conventional chemoembolization. Current(More)
PURPOSE To evaluate clinical outcomes after percutaneous treatment of superior mesenteric vein (SMV) thrombosis. MATERIALS AND METHODS A retrospective chart review was conducted of all patients with SMV thrombosis treated with percutaneous catheter-directed thrombectomy/thrombolysis. The demographics of the study population, potential causative factors(More)
Our objective was to evaluate the role of echoplanar diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) maps in the assessment of response of uterine fibroids and myometrium to uterine fibroid embolization (UFE). We evaluated 32 fibroids in 11 patients treated with UFE. Treated lesions had low ADC values compared to untreated lesions.(More)
PURPOSE To prospectively determine the feasibility of using diffusion-weighted (DW) imaging and apparent diffusion coefficient (ADC) mapping before (baseline) and after treatment and at 6-month follow-up to monitor magnetic resonance (MR) image-guided focused ultrasound surgical ablation of uterine fibroids. MATERIALS AND METHODS Informed consent was(More)
PURPOSE To evaluate the long-term clinical outcome of transcatheter embolotherapy in women with chronic pelvic pain caused by ovarian and pelvic varices. MATERIALS AND METHODS The study population included consecutive patients referred to a tertiary-care interventional radiology service from 1998 to 2003 because of a high degree of clinical suspicion of(More)
Uterine arteriovenous malformation (AVM) causes significant morbidity with vaginal bleeding. Traditional therapy is a hysterectomy with no potential for future pregnancy. We present a case of successful superselective embolization of uterine AVM using n-butyl cyanoacrylate with subsequent normal term pregnancy and uncomplicated vaginal delivery in 1 year.
