Purpose: To assess the scope and determining risk factors related to the development of pneumothorax throughout CT-guided biopsy of pulmonary lesions in coaxial and non-coaxial techniques and the outcome of its management.
Objectives: CT-guided ethanol-mediated renal sympathetic denervation in treatment of therapy-resistant hypertension was performed to assess patient safety and collect preliminary data on treatment efficacy.
It is postulated that focal IRE affords complete ablation of soft-tissue tumours while protecting the healthy peritumoral tissue. Therefore, IRE may be an interesting option for minimally invasive, kidney-tissue-sparing, non-thermal ablation of renal tumours.
Once reserved solely for non-surgical cases, percutaneous ablation is becoming an increasingly popular treatment option for a wider array of patients with small renal masses and the radiation risk needs to be better defined as this transition continues.
Purpose: To evaluate the frequency and the predictive factor of each feeding artery on intra-arterial infusion chemotherapy (IAIC) in primary tongue cancer.
Purpose: To identify factors associated with advanced inferior vena cava filter (IVCF) retrieval to raise awareness on technical considerations, retrieval efficiency, and patient safety.
Purpose: Although platelet reactivity is routinely inhibited with aspirin after percutaneous angioplasty (PTA) in peripheral arteries, the restenosis rate in the superficial femoral artery (SFA) is high. Interaction of activated platelets and the endothelium in the region of intervention could be one reason for this as collagen in the subendothelium activates platelets.
Purpose: Retrospective evaluation of 12-year experience with endovascular management of acute mesenteric ischemia (AMI) due to embolic occlusion of the superior mesenteric artery (SMA).
Purpose: This study was designed to evaluate the long-term clinical outcome and frequency of reinterventions in patients with uterine fibroids treated with embolization at a single center using polyvinyl alcohol microparticles.
Purpose: Transjugular intrahepatic portosystemic shunt (TIPS) creation is considered as being one of the most complex procedures in abdominal interventional radiology. Our aim was twofold: quantification of TIPS-related patient radiation exposure in our center and identification of factors leading to reduced radiation exposure.
OBJECTIVE. CT-guided lung biopsy is a well-established diagnostic method for pulmonary lesions. The aim of our study was to evaluate the diagnostic outcomes and safety profile of conventional CT–guided lung biopsies.
Transcatheter arterial chemoembolization (TACE) is the most commonly used local-regional treatment for unresectable hepatocellular carcinoma (HCC). The convention for decades has been to deliver concentrated chemotherapeutic solutions in an ethiodized oil emulsion (Ethiodol; Savage Laboratories, Melville, NY), with or without particulate embolization, which results in a favorable pharmacokinetic profile. However, this technique may result in inconsistent drug delivery and retention. Alternative vehicles have been developed by using calibrated ion-exchange polymer microspheres to allow consistent embolization and a predictable retention and elution of agents such as doxorubicin. Commercially available drug-eluting microsphere products include LC Beads (Biocompatibles/BTG, Farnham, United Kingdom) and QuadraSpheres (BioSphere/Merit Medical, South Jordan, Utah). These new vehicles may offer the opportunity to implement a higher level of standardization to HCC treatment.
Purpose: To identify predictors of oncologic outcomes after percutaneous radiofrequency ablation (RFA) of colorectal cancer liver metastases (CLMs) and to describe and evaluate a modified clinical risk score (CRS) adapted for ablation as a patient stratification and prognostic tool.
Purpose: To demonstrate the feasibility of free-breathing three-dimensional (3D) radial ultrashort echo time (UTE) magnetic resonance (MR) imaging in the simultaneous detection of pulmonary embolism (PE) and high-quality evaluation of lung parenchyma.
Purpose: To investigate the qualitative and quantitative impacts of labeling yttrium microspheres with increasing amounts of superparamagnetic iron oxide (SPIO) material for magnetic resonance (MR) imaging in phantom and rodent models.
