Radial access

Nikhil Cheerla, Olivier Gevaert
BACKGROUND: The current state-of-the-art in cancer diagnosis and treatment is not ideal; diagnostic tests are accurate but invasive, and treatments are "one-size fits-all" instead of being personalized. Recently, miRNA's have garnered significant attention as cancer biomarkers, owing to their ease of access (circulating miRNA in the blood) and stability. There have been many studies showing the effectiveness of miRNA data in diagnosing specific cancer types, but few studies explore the role of miRNA in predicting treatment outcome...

BACKGROUND: The continuous monitoring of vital parameters and subsequent therapy belong to the core duties of anaesthetists during acute trauma resuscitation in the trauma room. Important procedures may include placement of arterial lines and central venous catheters (CVCs). Knowledge of indication, performance and localization of invasive catheterisation of trauma care in Germany is scarce. METHODS: After approval of the German Society of Anaesthesiology and Intensive Care Medicine we conducted an online survey about arterial and central venous catheterisation of severely injured patients with consideration of common practice used by anaesthetists in German trauma rooms...

BACKGROUND: PCI has been done traditionally through transfemoral route. But now transradial and transbrachial routes are also coming up in practice. We compared transradial versus transfemoral routes for ease of operability, time for procedure, complications, and failure rates through a prospective study. METHODS: Four hundred Patients admitted in department of cardiology for percutaneous interventions were enrolled in the study. 200 patients were assigned to each group randomly...

OBJECTIVES: To assess the effect of image registration and averaging on the visualization and quantification of the radial peripapillary capillary (RPC) network on optical coherence tomography angiography (OCTA). METHODS: Twenty-two healthy controls were imaged with a commercial OCTA system (AngioVue, Optovue, Inc.). Ten 10x10° scans of the optic disc were obtained, and the most superficial layer (50-μm slab extending from the inner limiting membrane) was extracted for analysis...

See-through-wall coherent microwave scattering from resonance-enhanced multiphoton ionization (REMPI) for rotational temperature measurements of molecular oxygen has been developed and demonstrated in a flow reactor at atmospheric pressure. Through limited, single-ended optical access, a laser beam was focused to generate local ionization of molecular oxygen in a heated quartz flow reactor enclosed by ceramic heating elements. Coherent microwaves were transmitted, and the subsequent scattering off the laser-induced plasma was received, through the optically opaque ceramic heater walls and used to acquire rotational spectra of molecular oxygen and to determine temperature...

AIMS: To compare different radiation protection drapes in term of radiation dose absorbed by operators during right or left transradial procedures. METHODS AND RESULTS: Patients who underwent transradial coronary procedures were randomized initially in 4 groups: Group 1 (no drapes), Group 2 (drape on patient's arm), Group 3 (pelvic drape), Group 4 (combined arm and pelvic drapes). Subsequently each group was further randomized to right or left radial access. The primary end-point was the operator radiation dose at thorax...

We explore temperature dependence of the self, corrected and transport diffusivities of CO2, CH4 and N2 in a polyethylene (PE) polymer membrane through equilibrium Molecular Dynamics (EMD) simulations. We also investigate the morphology of the polymer membrane based on the intermolecular radial distribution function (RDF), free volume and pore size distribution analysis. The results indicate the existence of 1.5-3 Å diameter pores in PE membrane, and with increase in temperature the polymer swells linearly with changing slope at 450 K in the absence of gas and exponentially in the presence of gas...

Intravenous injection of drugs is associated with a host of medical complications, notably soft-tissue infections. On the contrary, intra-arterial injections of drugs have also been reported, largely restricted to inadvertent injections. Here we describe a patient who engaged in repeated intra-arterial injections of heroin when she exhausted most of her venous access, and presented acutely with a radial artery occlusion requiring thrombolytic therapy. Clinicians should have a high index of suspicion for intra-arterial injection in injection drug users who present with limb pain, ischemia, and motor/sensory deficits...

BACKGROUND: Transesophageal introduction of the endobronchial ultrasound (EBUS) videobronchoscope allows pulmonologists to perform endoscopic ultrasound fine-needle aspiration (EUS-B-FNA) of mediastinal lesions. Safety, diagnostic accuracy, and feasibility of EUS-B-FNA in evaluation of pulmonary parenchymal lesions are not established. METHODS: All patients undergoing pulmonologist-performed EUS-B-FNA of parenchymal lung lesions at 2 tertiary centers were included in this prospective observational cohort study...

Post-procedural upper extremity dysfunction (UED) remains one of the few potential questions about the overall benefits of the transradial approach (TRA) to endovascular procedures compared to femoral (TFA). Data on UED is limited, but the most comprehensive study curiously shows similar incidence of post-procedural UED with TFA as TRA. The effects of trAnsRadial perCUtaneouS coronary intervention on upper extremity function (ARCUS) study will investigate whether patient characteristics influence radial access outcomes such as UED...

The radial artery has gained favor as the access of choice for many operators due to a lower risk of vascular complications. The vascular anatomy of the left upper extremity may be more conducive to cardiac catheterization given reduced subclavian tortuosity. The left radial artery continues to be an arrow in the quiver of modern interventional cardiologist and may provide less radiation exposure when compared to the right radial artery.

Skull base surgical defects present unique challenges to anatomic and functional reconstruction. Fortunately, many endonasal skull base defects are successfully managed with a variety of local and regional reconstructive techniques. However, when prior surgery or radiotherapy eliminates the use of these local and regional reconstructive options, more elaborate free tissue transfer techniques are required. Managing endoscopic skull base defects of the anterior cranial fossa and clivus is further complicated by the limited access afforded for flap inset...
