Objectives: This study sought to investigate the association of local and segmental arterial stiffness with incident cardiovascular events and all-cause mortality.
Purpose: To identify retrospectively hypercoagulable events that occurred over time in patients who underwent image-guided percutaneous renal cryoablation and compare the incidence with a cohort of patients who underwent surgical partial nephrectomy (PN) during the same time period.
With ethics committee approval, records for 103 consecutive patients who underwent FBD with our interventional radiology service (1999–2011) were reviewed retrospectively. Patients underwent diagnostic contrast material–enhanced study prior to the first dilation. Dilations were performed by using general anesthesia. Outcomes were number and/or frequency of dilations, clinical effectiveness and response to dilations, esophageal perforation, requirement for surgery, and mortality. Data were expressed as mean ± standard deviation (with range). Comparisons were conducted by using the Fisher exact test and log-rank test. The significance level was set at P < .05.
To identify liver tumor characteristics associated with low (<10%), intermediate (10%–20%), and high (>20%) lung shunt fraction (LSF) at technetium 99m (99mTc) macroaggregated albumin (MAA) imaging performed before yttrium 90 (90Y) radioembolization (RE).
OBJECTIVE. After 90Y-microsphere radioembolization for unresectable hepatic neoplasms, the nearby gallbladder is susceptible to radiation-induced cholecystitis, an uncommon complication. The purpose of this study was to characterize the imaging findings after 90Y radioembolization of the gallbladder and to assess the incidence of clinically significant radiation-induced cholecystitis.
OBJECTIVE. The aim of our study was to evaluate the value of 3D registration images reconstructed by fusion of pre- and posttreatment CT or MRI for the assessment of ablative margins after percutaneous radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC).
OBJECTIVE. The purpose of this study was to investigate the safety and efficacy of CT-guided percutaneous cryoablation for the treatment of osteoid osteoma in adults.
Purpose: This study was designed to evaluate the feasibility of endovascular guidance by means of live fluoroscopy fusion with magnetic resonance angiography (MRA) and computed tomography angiography (CTA).
Purpose: Serious complications can result from nontarget embolization during yttrium-90 (Y-90) transarterial radioembolization. Hepatoenteric artery coil embolization has been traditionally performed to prevent nontarget radioembolization. The U.S. Food and Drug Administration–approved Surefire Infusion System (SIS) catheter, designed to prevent reflux, is an alternative to coils. The hypothesis that quantifiable SIS procedural parameters are comparable to coil embolization was tested.
Background: Prior unblinded studies have suggested that catheter-based renal-artery denervation reduces blood pressure in patients with resistant hypertension.
Background: The role of fibrinolytic therapy in patients with intermediate-risk pulmonary embolism is controversial.
Objective: Most clinicians regard angioplasty with or without stent placement to be the treatment of choice for transplant renal artery stenosis (TRAS). However, published results regarding its effectiveness are heterogeneous. The aim of this study was to assess the safety and efficiency of TRAS endovascular therapy.
Purpose: Multiple endovascular devices have been used for mechanical thrombectomy (MT) in basilar artery occlusion (BAO) for >10 years. Based on a single-center experience during the course of one decade, we present data on safety and efficacy of previous MT devices compared with modern stent retriever and suction thrombectomy.
Background: According to the Barcelona Clinic Liver Cancer (BCLC) algorithm, patients with advanced stage (BCLC-C) hepatocellular carcinoma (HCC) are recommended for systemic treatment or palliative therapy. However, chemoembolization with drug-eluting beads (DEB-TACE) has been shown to be safe in high-risk patients. The purpose of our study was to evaluate the safety and effectiveness of DEB-TACE in patients with an advanced-stage HCC.
Purpose: This study was designed to compare technical success and local recurrence rates of transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) with/without monitoring of embolized areas using cone-beam computed tomography (CBCT).
