AIM: This study investigated whether a high birth weight was associated with increased risk factors for cardiovascular disease when Swedish adults reached 34-40. METHODS: We studied 27 subjects born at Uppsala University Hospital in 1975-1979, weighing at least 4,500g, and compared them with 27 controls selected by the Swedish National Board of welfare with birth weights within ±1 standard deviations scores and similar ages and gender. The study included body mass index (BMI), blood pressure, lipid profile, haemoglobin A1c (HbA1c), C-reactive protein (CRP) and high frequency ultrasound measurements of intima-media thickness, intima thickness and intima:media ratio of the carotid and radial arteries...

An ideal non-invasive monitoring system should provide accurate and reproducible measurements of clinically relevant variables that enables clinicians to guide therapy accordingly. The monitor should be rapid, easy to use, readily available at the bedside, operator-independent, cost-effective and should have a minimal risk and side effect profile for patients. An example is the introduction of pulse oximetry, which has become established for non-invasive monitoring of oxygenation worldwide. A corresponding non-invasive monitoring of hemodynamics and perfusion could optimize the anesthesiological treatment to the needs in individual cases...

BACKGROUND: Radial artery access is the primary approach for coronary interventions due to higher safety profile in comparison to femoral access. Radial artery occlusion (RAO) is the main complication of transradial catheterization that can lead to severe symptoms and a permanent artery occlusion. The incidence of RAO after transradial access ranges from 5 to 38% and data regarding treatment is scarce. Whether anticoagulation and vasoactive medication provides an additional benefit in recovery of radial artery patency (RAP) after catheterization has not been investigated in detail...

BACKGROUND: Radial artery cannulation is extremely challenging in neonatal patients. Herein, we compared the success rate of the modified dynamic needle tip positioning short-axis, out-of-plane, ultrasound-guided technique with that of the traditional palpation technique in neonatal radial artery cannulation. METHODS: Sixty term neonates undergoing major abdominal surgery were randomized into the ultrasound or palpation group via the sealed-envelope method. The ultrasound group underwent radial artery cannulation using an ultrasonic apparatus, while traditional palpation of arterial pulsation was used in the palpation group...

Minimally invasive sublobar anatomical resection is becoming more and more popular to manage early lung lesions. Robotic-assisted thoracic surgery (RATS) is unique in comparison with other minimally invasive techniques. Indeed, RATS is able to better integrate multiple streams of information including advanced imaging techniques, in an immersive experience at the level of the robotic console. Our aim was to describe three-dimensional (3D) imaging throughout the surgical procedure from preoperative planning to intraoperative assistance and complementary investigations such as radial endobronchial ultrasound (R-EBUS) and virtual bronchoscopy for pleural dye marking...

The posterior antebrachial cutaneous nerve branches from the radial nerve proximal to the elbow and supplies sensation to the posterior aspect of the forearm. With a high-frequency linear transducer, the posterior antebrachial cutaneous nerve was identified in 8 healthy volunteers. Under aseptic conditions and with an ultrasound-guided in-plane technique, 1% lidocaine was injected circumferentially around the nerve. In each participant, the block was successful, and neither incidental blocks of other nerves nor any other complications were observed...

Nowadays we use novel diagnostic equipment for lung cancer. Bronchoscopy was the tip of the arrow for diagnosis, however; ultrasound systems have brought a revolution. We have the radial-endobronchial ultrasound for peripheral lesions and the convex probe endobronchial ultrasound for central lesions. Ultrasound endoscopic systems can be used for the diagnosis of any lesion that can be approached from the airways. In the current manuscript we will present two methods for the biopsy of thyroid gland. The first method is using anesthisiological tools and the second tools from the ear, nose and throat department...

BACKGROUND: Pancreatic cysts are being diagnosed more frequently because of the increasing usage of imaging techniques. A pseudocyst with the major diameter of 10 cm is termed as a giant cyst. Asymptomatic pseudo-cysts up to 6 cm in diameter can be safely observed and monitored without intervention, but larger and symptomatic pseudocysts require intervention. CASE PRESENTATION: A 27-year-old Sri Lankan male, with history of heavy alcohol use, presented with progressive abdominal distension following an episode of acute pancreatitis...

INTRODUCTION: Brachial artery aneurysms are relatively uncommon and generally due to infectious, post-traumatic or iatrogenic etiology. They seem to affect 4.5% of arteriovenous fistula. The usual manifestation is an accidental finding of a pulsatile, painless, and asymptomatic mass. Complications include sac thrombosis, thromboembolic ischaemic events, and disruption with profuse bleeding. METHODS: The aim of this study is to present a case of true brachial artery aneurysm in end-stage renal disease patient after arteriovenous fistula creation...

Non-invasive vascular elastography can evaluate the stiffness of the carotid artery by visualizing the vascular strain distribution. Axial strain estimates of the longitudinal cross section of the carotid artery are sensitive to the angle between the artery and the transducer. Anatomical variations in branching and arching of the carotid artery can affect the assessment of arterial stiffness. In this study, we hypothesized that principal strain elastograms computed using compounded plane wave imaging can reliably visualize the strain distribution in the carotid artery, independent of the transducer angle...
