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. Our aim was to assess a novel embolic agent precipitating hydrophobic injectable liquid (PHIL) this is currently used in the treatment by neuro-interventionists in the treatment of cerebral arterio-venous malformations.
Purpose: The purpose of this study was to describe a novel system for treating advanced head and neck cancer consisting of an external carotid arterial sheath (ECAS) and a microcatheter to inject drugs retrogradely into multiple feeding arteries through the superficial temporal artery (STA).
Objective: To assess the technical feasibility and safety of combined fusion imaging and needle tracking under ultrasound guidance to target bone lesions without cortical disruption.
Objective: Conventional multiplanar reconstruction (MPR) imaging can be used as a tool for planning oblique puncture procedures, but it takes a few minutes to reconstruct and is not appropriate for real-time CT fluoroscopy-assisted puncture. Recently, new MPR technology has been used that requires only 8 s and makes it possible to obtain a nearly real-time CT fluoroscopy-assisted oblique puncture. We refer to it as “direct MPR.” This is the first clinical report of this technique.
Objectives: In vitro and in vivo evaluation of fast- and slow-release gemcitabine-eluting hydrogel (GEH) devices.
Purpose: Covered stents have been demonstrated to reduce restenosis; however, the membrane’s limited biocompatibility can still lead to thrombus formation. To obtain optimal surface hemocompatibility, endothelialization of the luminal surface has been proposed. However, the effect of delivery procedures, such as crimping and balloon dilatation, on the endothelial layer has not been quantified. This study investigated the impact of such procedures on endothelialized covered stents in vitro.
Purpose: This study was designed to evaluate the safety and efficacy of CT-guided drainage of the pericardial effusion in patients after cardiac surgery.
Purpose: To determine the correlation of pre-procedural and imaging characteristics with lung shunt fraction (LSF) measured by technetium-99 m macroaggregated albumin (99mTc-MAA) scan in patients with hepatocellular carcinoma.
Purpose: To evaluate the safety and efficacy of yttrium-90 radioembolization (RE) following left or right hepatic lobectomy.
Background: To evaluate the course of pro- and anti-inflammatory cytokines after 90Y-radioembolization (RE) of liver malignancies and to identify prognosticators for liver-related adverse events and survival.
Lower urinary tract symptoms (LUTS) are one of the most common health issues in men and pose a significant economic challenge in healthcare. Transurethral resection of the prostate (TURP) remains the gold standard surgical treatment for medically refractive LUTS secondary to benign prostatic hyperplasia. The institution of medical therapy and the development of several minimally invasive surgical therapies (MISTs) began in the 1980’s and 1990’s. Together, these therapies brought about a change in the natural course of the disease, stimulating investigation into the economic consequences of various management approaches. TURP has been observed to have higher complication rates, but better efficacy and lower retreatment rates compared to MISTs. Staying abreast of the evolving understanding of LUTS and the alternative treatment options is imperative for radiologists.
Objectives: The main goal of the study was to evaluate sexual function before and one year after UFE. The secondary goals were to evaluate the quality of life before and one year after UFE and to determine the relation of imaging findings (MRI data) before and 3–6 months after UFE to changes in sexual function and quality of life.
Background: Bronchial artery embolisation (BAE) is recommended for the treatment of massive haemoptysis in cystic fibrosis (CF), but there are no randomised controlled trials of this therapy and its role in sub-massive haemoptysis is unclear. This study aimed to determine the outcomes and safety of BAE in adults with CF.
Purpose: Intraprocedural distal embolization is an accepted complication of femoropopliteal angioplasty. The purpose of this study is to assess the use of below-the-knee stents in the “bail-out” of conventional methods.
Purpose: To evaluate the hemodynamic effect of percutaneous transluminal intervention (PTI) on stenosis of the superficial femoral (SFA) and popliteal arteries (PA) using time–density curves (TDCs) derived from digital subtraction angiography (DSA) series in correlation with ultrasound peak systolic velocity ratio (PSVR) and ankle brachial index (ABI).
