Transradial access (TRA) has been associated with improved post-procedure hemostasis and patient satisfaction, and decreased hemorrhagic complications, sedation requirements, recovery times, and procedure-related costs when compared with traditional transfemoral catheterization. Supine TRA has been described for the treatment of myocardial infarctions, aortoiliac and femoropopliteal stenoses, and a variety of neoplasms. This original research describes prone transradial catheterization to facilitate combined single-session transarterial embolization and percutaneous cryoablation of solid neoplasms from a posterior approach without repositioning...

The direct oral anticoagulants (DOACs) have emerged as a good alternative for the treatment of thromboembolic diseases, and their use in clinical practice is increasing rapidly. The DOACs act by blocking the activity of one single step in the coagulation cascade. These drugs act downstream in the common pathway of the coagulation cascade by directly antagonising the action of thrombin or factor Xa. The development of DOACs represents a paradigm shift from the oral vitamin K antagonists such as warfarin. This article aims to describe the properties of the currently available DOACs including pharmacology and dosing...

PURPOSE: Recurrent spontaneous hemarthrosis is an infrequent but debilitating late complication of joint replacement, affecting up to 1.6% of patients with arthroplasty of the affected joint. Repeated episodes of bleeding result in an inflammatory cascade that further propagates bleeding events. Open and arthroscopic synovectomy are often performed when conservative treatments fail. Transarterial embolization is increasingly utilized as a less invasive option; however, its role is not widely established...

Early focus of interventional oncologists was developing tools and imaging guidance, performing "procedures" acting as a skillful technician without knowledge of clinical patient outcomes, beyond post-treatment image findings. Interventional oncologists must deliver "treatments" and not "procedures", and focus on clinically relevant outcomes, provide clinical continuity of care, which means stand at multidisciplinary tumor boards, see patients in consultation before treatment and for follow-up. Interventional oncologists have fought for the same "market" with surgery in a head to head, bloody competition called red ocean strategy in marketing terms, resulting in many aborted trials...

INTRODUCTION: We hypothesize that the combination of transarterial embolization (TAE) plus inhibition of lactate export will limit anaerobic metabolism and reduce tumor survival compared to TAE alone. The purpose of this study was to test this hypothesis in a rat model of hepatocellular carcinoma (HCC). METHODS: Rat N1-S1 hepatoma cells were assayed in vitro using the Seahorse XF analyzer to measure extracellular acidification (lactate excretion) comparing effects of the addition of caffeic acid (CA) or ferulic acid (FA) or UK-5099 with control...

This report describes perioperative hemodynamic monitoring of the common hepatic artery (CHA) during endovascular treatment of a pancreaticoduodenal arcade aneurysm, in a patient with celiac artery stenosis caused by the median arcuate ligament. Pressure monitoring was performed as a safety measure against critical complications such as liver ischemia. As the aneurysm was located in the anterior pancreaticoduodenal artery (APDA) and the posterior pancreaticoduodenal artery (PPDA) was small in caliber, the patient was considered to be at a high risk of liver ischemia...

Bronchial artery embolization is now a common treatment for massive pulmonary hemoptysis if flexible bronchoscopy at the bedside failed to control the bleeding. Complications of this technique range from benign chest pain to devastating neurological impairments. We report the case of a 41-year-old man who developed an ST elevation myocardial infarction during bronchial artery embolization, presumably because of coronary embolism by injected particles. In this patient who had no previously known coronary artery disease, we retrospectively found a communication between the left bronchial artery and the circumflex coronary artery...
