Purpose: To report on the first clinical experience with perfusion angiography (PA) of the foot in patients with chronic critical limb ischemia.
Purpose: Approximately 83 % of patients with bladder cancer have achieved a complete response after undergoing a novel bladder preservation therapy involving balloon-occluded intra-arterial infusion chemotherapy (BOAI) using a four-lumen double-balloon catheter, known as the Osaka Medical College regimen. This study aimed to show the quantitative difference in hemodynamics of the bladder arteries using syngo iFlow (Siemens Healthcare, Erlangen, Germany), which provides an automatic tool for quantitative blood flow analysis between double BOAI (D-BOAI) and conventional single BOAI (S-BOAI).
Objective: To summarize our early experience gained from the chimney technique for type B aortic dissection (TBAD) extending to the aortic arch and to evaluate the aortic remodeling in the follow-up period.
Purpose: To optimize a C-arm computed tomography (CT) protocol for radioembolization (RE), specifically for extrahepatic shunting and parenchymal enhancement.
Purpose: The purpose of our study is to determine if there is a relationship between dose deposition measured by PET/MRI and individual lesion response to yttrium-90 (90Y) microsphere radioembolization.
Purpose: To evaluate the technical feasibility and clinical efficacy of osteoid osteoma (OO) cryoablation in a large, pediatric/adolescent cohort.
Balloon-occluded retrograde transvenous obliteration (BRTO) is an effective and minimally invasive treatment for isolated gastric varices (GVs) that is usually performed through a gastrorenal shunt (GRS) or gastrocaval shunt (GCS). However, there are some cases in which GVs drain mainly into the left pericardiophrenic vein without an accessible GRS or GCS. This brief report presents four cases of GVs without a GRS/GCS treated by BRTO through the pericardiophrenic vein. BRTO was successfully performed with the use of flexible balloon catheters without any complications in all four patients, and the GVs were completely obliterated.
The present update from the Safety and Health Committee of the Society of Interventional Radiology reviews Ebola virus disease (EVD) and the important points relevant to interventional radiology (IR) professionals who may encounter patients with or suspected to have EVD. The aim of this article is to shed some light on the perceptions and misconceptions of preparedness and protection of patients and hospital staff. This document also reviews the Centers for Disease Control and Prevention (CDC) guidelines related to personal protective equipment (PPE) and management of patients with EBV by health care workers in the United States. Finally, we present two potential EVD scenarios to put prevention and procedure into perspective.
Purpose: To assess the clinical utility of iliac vein stent placement for patients with chronic limb edema or pelvic congestion presenting with nonocclusive May–Thurner physiology.
Background: Uncontrolled arterial hypertension is a frequent problem after successful repair of CoA and has been attributed to increased central sympathetic drive as well as a blunted baroreceptor reflex. RSD is a promising therapy to reduce central sympathetic drive and improve baroreflex sensitivity.
Background: Renal denervation (RDN) has been shown to reduce blood pressure (BP), muscle sympathetic nerve activity (MSNA) and target organ damage in patients with resistant hypertension (RH) and bilateral single renal arteries. The safety and efficacy of RDN in patients with multiple renal arteries remains unclear.
Background: Renal sympathetic denervation (RSD) is currently being investigated in multiple studies of sympathetically driven cardiovascular diseases such as heart failure and arrhythmias. Our aim was to assess systemic and cardiac sympatholytic effects of RSD by the measurement of cardiac sympathetic activity and cardiovascular parameters.
Chronic kidney disease (CKD) induces cardiac remodeling including left ventricular hypertrophy (LVH), and cardiac fibrosis. Several clinical studies, including those who recruited participants with mild to moderate reduction in estimated glomerular filtration rate (eGFR) showed an independent association between CKD and LVH. Specifically, there is a progressive increase in the prevalence of LVH and increased left ventricular mass when the eGFR decreases. In addition, among participants in a study including patients with more advanced kidney disease on dialysis, contrast magnetic resonance image (MRI) demonstrates a diffuse pattern image with gadolinium uptake suggestive of fibrosis and non-ischemic cardiomyopathy.
Objective: The aim of the study was to assess the utilization of catheter-directed thrombolysis (CDT) and its comparative effectiveness against systemic thrombolysis in acute pulmonary embolism (PE).
Background: In selected patients with hypertension, renal artery (RA) stenting is used to treat significant atherosclerotic stenoses. However, blood pressure often remains uncontrolled after the procedure. Although catheter-based renal denervation (RDN) can reduce blood pressure in certain patients with resistant hypertension, there are no data on the feasibility and safety of RDN in stented RA.
