Access via the internal jugular vein [PDF]

open access: yes, 2008
Central venous access via the internal jugular vein (IJV) is safe, relatively easy and very commonly used in infants and children undergoing cardiac surgery for congenital heart disease. Because of the wide range of anatomical variations an ultrasound-

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.

Outflow boundary conditions for 3D simulations of non-periodic blood flow and pressure fields in deformable arteries [PDF]

open access: yes, 2010
The simulation of blood flow and pressure in arteries requires outflow boundary conditions that incorporate models of downstream domains. We previously described a coupled multidomain method to couple analytical models of the downstream domains with 3D ...

Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

open access: yesAdvanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.

Congenital absence of the internal carotid artery with intercavernous anastomosis

open access: yesRadiology Case Reports, 2019
Congenitally absent internal carotid artery with intercavernous anastomosis is an exceedingly rare vascular anomaly. We report such a case in a 65-year-old man with chronic symptoms resembling sporadic transient ischemic attacks. While these patients are

Facts and Misfacts on D‐Dimer Testing. Consensus Guidance From the Italian Society on Thrombosis and Hemostasis (SISET)

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT D‐dimer defines degradation products derived from the proteolysis mediated by plasmin on cross‐linked fibrin. The evidence‐based use of D‐dimer in some conditions has been consolidated. Currently, however, there is an entrenched prescription of D‐dimer testing to screen otherwise healthy subjects that may induce prescribing physicians to start
