Background Transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) frequently causes feeding artery stenosis or occlusion that may interfere with repeated treatment. Purpose To investigate the incidence and predictors of hepatic arterial damage (HAD) after drug-eluting bead-TACE (DEB-TACE) in comparison with conventional TACE (Conv-TACE). Material and Methods We retrospectively analyzed 54 patients who underwent DEB-TACE for HCC as an initial treatment with follow-up angiography

Abstract Manual vascular interventional radiology (VIR) procedures have been performed under radiation exposure conditions, and many commercial master–slave VIR robot systems have recently been developed to overcome this issue. However, master–slave VIR robot systems still have limitations. The operator must reside near the master device and control the slave robot using only the master device. In addition, the operator must simultaneously process the recognition of the surgical tool from the X-

Conventional vascular intervention (VI) procedures are typically performed manually under exposure to X-rays, whereby several problems are presented that need to be addressed owing to the patients and doctors being exposed to large amounts of radiation. In such cases, employing radiation protection units is not a long-term solution to avoid physical damage. Therefore, to overcome these issues, we propose a robotic VI system in this study. Moreover, we compare the extent of radiation exposure in

BACKGROUND: The purpose of this study was to evaluate the safety and usefulness of fluoroscopy-guided percutaneous gastrostomy (FPG) in patients with amyotrophic lateral sclerosis (ALS) using a large-profile gastrostomy tube accompanied by the pull technique. This procedure was done without an accompanying endoscopy or gastropexy. METHODS: Thirty-six patients with ALS underwent FPG using a large-profile gastrostomy tube accompanied by the pull technique. A 24 Fr pull-type tube was inserted under
