OBJECTIVES: We aimed to detect if pre-procedure vascular ultrasound scanning (VUS) of radial arteries (RAs) can increase the radial access success (RAS) rate and/or reduce the vascular access time (VAT), by guiding the choice of the proper access site for repeated trans-radial interventions (TRIs). BACKGROUND: Currently, repeated-TRIs are encountered more frequently in most of the cath. labs. However, structural changes of the RAs after TRA may hinder it is usage for repeated-TRI...

Extracorporeal membrane oxygenation (ECMO) and extracorporeal life support (ECLS) are an increasingly established advanced therapy for emerging severe lung and/or cardiocirculatory dysfunction or failure. Several reports have provided evidence for a potential benefit in prognosis by ECLS in cases of cardiogenic shock including cardiopulmonary resuscitation. Routine use in specialized centers reduces the incidence of negative side effects (e.g., vascular/ischemic, embolic, hemorrhagic, hemolytic and, furthermore, septic)...

Retroperitoneal hemorrhage from iliac artery injury is a potentially serious complication of vascular interventional procedures leading to hemorrhagic shock and death if not diagnosed early and treated promptly. We report a 70-year-old male admitted to our facility with non-ST-elevation myocardial infarction, whose heart catheterization revealed left anterior descending artery (LAD) with 80% proximal, 95% mid and 100% distal disease. The left circumflex and right coronary arteries were 100% occluded proximally and received collaterals from the LAD...

BACKGROUND: We previously showed that using the radial artery access site as opposed to the femoral artery site decreases the radiation exposure of patients during coronary artery interventions. The objective of this study was to compare radiation exposure levels of the operating physician during coronary interventions when incorporating both radial and femoral artery approaches. METHODS: The study assessed all coronary angioplasties performed in a major metropolitan general hospital...

BACKGROUND: Extreme lateral interbody fusion (XLIF) has rapidly become a popular operative procedure for lumbar canal stenosis and scoliosis. This approach provides direct access to the lateral aspect of the disc with minimal disruption of spinal structures, including ligaments and muscles. However, it involves risk of injuries to the lumbar nerve plexus, segmental artery and intestinal tract because of the limited surgical field. This study aimed to clarify the benefit of using a microendoscope to prevent these injuries...

INTRODUCTION: Elderly patients (≥75 years) undergoing coronary angioplasty are increasing. Meta-analyses have shown the benefits of radial access which might reduce hospital stay by decreasing access site complications with associated secondary benefits, however, the population over the age of 75 years were not a large part of the cohort and may behave differently due to increased atherosclerotic burden and age-related vascular changes. In addition, complications unique to this age group such as delirium and deconditioning might occur which could have a bearing on the outcome...

INTRODUCTION: The aim of this study was to evaluate in vitro and ex vivo roles of bortezomib, a proteasome inhibitor that binds to the active site of the 26S proteasome, in tertiary dentin formation. METHODS: We established pulpal access cavity preparation that was treated with or without bortezomib before direct pulp capping with a calcium hydroxide-based material. We also analyzed bone morphogenetic protein (Bmp)- and Wnt-related signaling molecules using quantitative real-time polymerase chain reaction...

INTRODUCTION: Vascular closure devices (VCDs) are designed to achieve rapid hemostasis during percutaneous coronary and peripheral vascular procedures. Studies demonstrate that VCDs improve time to hemostasis (TTH) and time to ambulation (TTA) in comparison to standard manual compression. The available products, however, typically have 13-17 steps in their application, often require hemostatic collagen or other agents as part of the process, and can result in significant scarring at the puncture site that can impact future access...

BACKGROUND: There is an increasing trend towards shorter hospital stays after transcatheter aortic valve implantation (TAVI), in particular for patients undergoing the procedure via transfemoral (TF) access. Preliminary data suggest that there exists a population of patients that can be discharged safely very early after TF-TAVI. However, current evidence is limited to few retrospective studies, encompassing relatively small sample sizes. METHODS: The Feasibility And Safety of early discharge after Transfemoral TAVI (FAST-TAVI) registry is a prospective observational registry that will be conducted at 10 sites across Italy, the Netherlands and the UK...

BACKGROUND: Advanced stage cancer treatments are often invasive and painful-typically comprised of surgery, chemotherapy, and/or radiation treatment. Low transport efficiency during systemic chemotherapy may require high chemotherapeutic doses to effectively target cancerous tissue, resulting in systemic toxicity. Nanotherapeutic platforms have been proposed as an alternative to more safely and effectively deliver therapeutic agents directly to tumor sites. However, cellular internalization and tumor penetration are often diametrically opposed, with limited access to tumor regions distal from vasculature, due to irregular tissue morphologies...

OBJECTIVES: Transcatheter aortic valve implantation is a well-recognized treatment option for high-risk patients with aortic stenosis. The femoral approach is possible in 80% of cases and remains the access of choice. When this approach is not feasible, other alternative routes have been proposed such as transapical, transaortic and subclavian. Transcarotid aortic valve implantation has been proposed as another direct vascular access. Its use is relatively new and still under evaluation...

The transradial approach (TRA) for coronary angiography and percutaneous coronary intervention is associated with lower rates of vascular complications and acute kidney injury when compared to the transfemoral approach (TFA). Urine metabolites and proteins may be useful in identifying the dynamic changes at the vascular endothelial cell level. We attempted to explore the changes in the measurable signals of endothelial and nephron injury within 60 to 90 minutes after catheterization among those with the TRA and TFA approaches...

BACKGROUND: When the common femoral artery is not accessible for infrainguinal bypass grafting, the profunda femoris artery (PFA) can be a valuable alternative inflow source for distal arterial revascularization. The purpose of this retrospective study was to evaluate the results of infrageniculate bypass grafting via the PFA as inflow source for critical limb ischemia. METHODS: Between 1994 and 2016, 68 patients, 51 men of a mean age of 74 years, underwent an infrageniculate arterial bypass grafting for critical limb ischemia, using the PFA as inflow site...

Extensive de novo vascularization of leafy galls emerging upon Rhodococcus fascians infection is achieved by fascicular/interfascicular cambium activity and transdifferentiation of parenchyma cells correlated with increased auxin signaling. A leafy gall consisting of fully developed yet growth-inhibited shoots, induced by the actinomycete Rhodococcus fascians, differs in structure compared to the callus-like galls induced by other bacteria. To get insight into the vascular development accompanying the emergence of the leafy gall, the anatomy of infected axillary regions of the inflorescence stem of wild-type Arabidopsis thaliana accession Col-0 plants and the auxin response in pDR5:GUS-tagged plants were followed in time...

Percutaneous transfemoral transcatheter aortic valve implantation (TF-TAVI) is generally an acceptable procedure but may be associated with vascular complications at femoral access sites, particularly in obese patients. This report aimed to describe a case of successful performance of our "double crossover technique" in an obese patient undergoing TF-TAVI with a percutaneous transfemoral intra-aortic balloon pump (TF-IABP). A 75-year-old man presented with heart failure due to a left ventricular ejection fraction of 35% and low-flow, low-gradient severe aortic stenosis...

Patients with severe accidental hypothermia require active rewarming. External rewarming may not be successful in severe hypothermia, and use of invasive techniques is limited to regional centers and is associated with vascular access site and other complications. We present a patient with severe accidental hypothermia who was successfuly rewarmed using a novel esophageal heat transfer device. A 55-year-old male (175 cm, 71 kg) was admitted with the first recorded temperature 23.3°C. Rewarming using renal replacement therapy circuit was unsuccessful because of severe hypotension...
