PURPOSE: We investigated the possibility of shortening the time required for loading epirubicin into calibrated polyvinyl alcohol-based hydrogel beads (DC Beads(®)) to be used for transarterial chemoembolization. METHOD: After separating the beads suspended in phosphate-buffered saline (PBS) solution by the use of a sieve (clearance 75 µm), epirubicin hydrochloride (EH) was loaded for 20, 30, or 60 s under vibration into DC beads. The EH loading rate into conventionally prepared (control) beads, i...

PURPOSE: To determine the accuracy of automatic and manual co-registration methods for image fusion of three-dimensional computed tomography (CT) with real-time ultrasonography (US) for image-guided liver interventions. MATERIALS AND METHODS: CT images of a skills phantom with liver lesions were acquired and co-registered to US using GE Logiq E9 navigation software. Manual co-registration was compared to automatic and semiautomatic co-registration using an active tracker...

We report a unique case of neonatal mycotic internal iliac artery aneurysm managed non-operatively. The child had multifocal osteomyelitis and no history of umbilical artery catheterisation. The aneurysm was regularly scanned and monitored until its obliteration by thrombus 17 days after initial detection. Contingency plans for either interventional radiological coiling or open surgical repair were in place had the aneurysm grown or the child deteriorated.

PURPOSE: Several scoring systems that guide patients' treatment regimen for transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) have been introduced, but none have gained widespread acceptance in clinical practice. The purpose of this study is to externally validate the Selection for TrAnsarterial chemoembolization TrEatment (STATE)-score and START-strategy [i.e., sequential use of the STATE-score and Assessment for Retreatment with TACE (ART)-score]. MATERIALS AND METHODS: From January 2000 to September 2015, 933 patients with HCC underwent TACE at our institution...

PURPOSE: To demonstrate the use of "Smart Puncture," a smartphone application to assist conventional CT-guided puncture without CT fluoroscopy, and to describe the advantages of this application. MATERIALS AND METHODS: A puncture guideline is displayed by entering the angle into the application. Regardless of the angle at which the device is being held, the motion sensor ensures that the guideline is displayed at the appropriate angle with respect to gravity. The angle of the smartphone's liquid crystal display (LCD) is also detected, preventing needle deflection from the CT slice image...

OBJECTIVE: Endovascular aortic aneurysm repair has become the principle technique used to treat abdominal aortic aneurysms. However, its long-term success is limited by complications, including type II endoleaks from lumbar arteries and the inferior mesenteric artery. Treatment of these endoleaks can be difficult. The most commonly performed procedure is embolisation via mesenteric or iliolumbar vessels. Embolic agents currently used include coils, glue and Onyx, all of which have their limitations...

PURPOSE: To investigate the clinical impact of performing prostate artery embolization (PAE) on patients with adenomatous-dominant benign prostatic hyperplasia (AdBPH). MATERIALS AND METHODS: Twelve patients from the ongoing proSTatic aRtery EmbolizAtion for the treatMent of benign prostatic hyperplasia (STREAM) trial were identified as having AdBPH; defined as two or more adenomas within the central gland of ≥1 cm diameter on multi-parametric MRI (MP-MRI). These patients were age-matched with patients from the STREAM cohort, without AdBPH...

PURPOSE: To determine current practice regarding screening, management, and follow-up of pulmonary arteriovenous malformations (PAVMs), particularly those with feeding arteries <3 mm in diameter, in those patients with hereditary hemorrhagic telangiectasia (HHT) at HHT Centers of Excellence. MATERIALS AND METHODS: A 32-question survey focusing on PAVM screening, management, and follow-up was sent to 147 participants at HHT Centers worldwide. RESULTS: Thirty-three responses were received (22%); 60% from interventional radiologists and 20% from pulmonologists; 67% from the USA, 21% European, and 6% Asian...

PURPOSE: To evaluate the effect of bariatric arterial embolization (BAE) with non-spherical polyvinyl alcohol (PVA) particles on systemic ghrelin levels, weight change, and gastric ulceration risk in a swine model. MATERIALS AND METHODS: From March 2014 to February 2015, ten healthy swine were used in the study (mean weight 31.5 kg; range 24.0-41.5 kg). The animals were randomly assigned to two groups: the embolized group (n = 5) in which BAE was performed and the control group (n = 5)...

OBJECTIVE: To evaluate the safety and efficacy sodium tetradecyl sulfate and lipiodol foam (STS foam) in BRTO for large (caliber ≥15 mm) porto-systemic shunt and gastric fundal varices. MATERIALS AND METHODS: It is a retrospective record-based study of patients who underwent BRTO using STS foam at the Institute of Liver and Biliary Sciences, New Delhi, for gastric variceal bleed or refractory hepatic encephalopathy (HE) who had large porto-systemic shunt (diameter ≥15 mm) with or without associated gastric varices...

PURPOSE: To evaluate the feasibility of short-segment coil embolization between 2 balloons for tight packing in an experimental vascular model. MATERIALS AND METHODS: Three coil embolization techniques were performed by 5 interventional radiologists as follows: (1) proximal balloon technique (proximal BT) which involved proximal balloon inflation and coil deployment over the balloon, (2) distal balloon technique (distal BT) which involved distal balloon inflation and coil deployment at the proximal side of the inflated balloon, and (3) double-balloon technique (DBT) which involved coil deployment between 2 inflated balloons...

PURPOSE: To evaluate the feasibility of a novel curved CT-guided biopsy needle prototype with shape memory to access otherwise not accessible biopsy targets. METHODS AND MATERIALS: A biopsy needle curved by 90° with specific radius was designed. It was manufactured using nitinol to acquire shape memory, encased in a straight guiding trocar to be driven out for access of otherwise inaccessible targets. Fifty CT-guided punctures were conducted in a biopsy phantom and 10 CT-guided punctures in a swine corpse...

OBJECTIVE: This study aimed to retrospectively evaluate the efficacy and safety of preoperative transcatheter arterial embolization (pTAE) for treating nasopharyngeal angiofibroma (NPAF). METHODS: Seventy-four NPAF patients were hospitalized for elective surgical treatment with pTAE (pTAE group, n = 32) or surgical treatment alone (non-pTAE group, n = 42) between January 1990 and December 2013. The following outcome measures were retrospectively analyzed and compared: intraoperative bleeding volume, surgery time (ST), duration of postoperative hospital stay (PHS), and disease recurrence...

PURPOSE: We report three cases of spontaneous prostatic tissue elimination through the urethra while voiding following technically successful prostatic artery embolization (PAE) as a treatment for lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH). METHODS: All patients were embolized with 100- to 300-μm microspheres alone or in combination with 300- to 500-μm microspheres. RESULTS: During follow-up prior to eliminating the tissue fragments, the three patients all presented with intermittent periods of LUTS improvement and aggravation...

Anthony M Esparaz, Muneeb Ahmed
Local and systemic reactions to implanted metallic devices, particularly to those containing nickel, are well documented. Metal ions are released due to exposure of the metal to blood, proteins, other body fluids, and sheer mechanical stress. Metal ions then complex with native proteins and become antigens, which can elicit hypersensitivity reactions. Another case report depicts a specific allergic complication (early stent occlusion) related to metallic biliary stent implantation. We present a case of allergic symptoms, associated with eating, in a patient who developed nickel sensitivity after biliary metal stent placement confirmed by allergic skin testing to the same metallic biliary stent placed one year earlier...
