OBJECTIVE. The purpose of this study was to evaluate the effectiveness of ultrasound-guided cryoablation in treating small invasive ductal carcinoma and to assess the role of contrast-enhanced (CE) MRI in determining the outcome of cryoablation.
OBJECTIVE. The purpose of this study was to evaluate the incidence, prognostic factors, and secondary management of stent migration in patients with malignant esophageal strictures.
OBJECTIVE. The purpose of this study is to investigate the incidence, management, and outcomes of esophageal perforation after fluoroscopic balloon dilation in 820 adult patients with esophageal diseases.
OBJECTIVE. Ureteroarterial fistula (UAF) is an uncommon condition with only approximately 150 cases reported in the literature. Patients typically present with hematuria in the setting of prolonged ureteral stenting, prior pelvic surgery, malignancy, or radiation. Presentation can vary from intermittent hematuria to life-threatening hemorrhagic shock.
Purpose: To study the effectiveness of prophylactic embolization of hepaticoenteric arteries to prevent gastrointestinal complications during radioembolization.
The National Patient Safety Goals program was established by The Joint Commission in 2002 to help accredited organizations address areas of concern regarding patient safety in the United States. The Universal Protocol, adopted by The Joint Commission in 2003, is included in the National Patient Safety Goals to prevent wrong person, wrong procedure, and wrong site surgery in all surgical and nonsurgical invasive procedures. These guidelines have been applied specifically to the practice of interventional radiology (IR); however, a pre–procedure checklist tailored to IR may further improve patient safety and outcomes.
Purpose: Interventional radiology (IR) has historically failed to fully capture the value of evaluation and management services in the inpatient setting. Understanding financial benefits of a formally incorporated billing discipline may yield meaningful insights for interventional practices.
Purpose: To evaluate preliminary outcomes after microwave ablation (MWA) of hepatocellular carcinoma (HCC) up to 5 cm and to determine the influence of tumor size.
Although the risk of adverse events from image-guided and interventional radiologic procedures is low, adverse events do occur, and there is evidence that inadequate resources and staffing can be associated with poorer outcomes
Background and Purpose: In CT fluoroscopy (CTF)-guided cervical transforaminal epidural steroid injection (TFESI), the majority of radiation dose is contributed by the planning CT scan rather than the CTF procedure itself. We replaced the planning helical CT with a spot CTF and accordingly changed the patient posture during scout and planning scans. The aim of this study was to test whether radiation dose reduction would be achieved by this protocol modification while still maintaining technical performance.
Purpose: To evaluate the technical feasibility and clinical efficacy of placement of a newly designed Y-shaped branched covered stent for palliative treatment of malignant hilar biliary obstruction.
Purpose: Hepatic artery pseudoaneurysms are a rare but potentially life-threatening complication of major pancreaticobiliary surgery. We evaluated the safety and efficacy of endovascular stentgraft implantation for the management of such vascular lesions.
Purpose: To evaluate long-term results of stent placement retrospectively in patients with outflow block after living-donor-liver transplantation (LDLT).
Purpose: We aimed to characterize the clinical profile, etiology, and outcomes of young Chinese patients with Budd–Chiari syndrome treated with recanalization.
