Consistent anatomic accessibility, ease of cannulation, and a low rate of complications have
made the radial artery the preferred site for arterial cannulation. Radial artery catheterization …

Assessment of collateral circulation to the hand is required prior to invasive procedures or
harvesting of the radial artery (RA). A modified Allen's test (MAT) is commonly used to …

Smart rings provide unique opportunities for continuous physiological measurement. They
are easy to wear, provide little burden in comparison to other smart wearables, are suitable …

Objective: We describe a novel machine-learning based method to estimate total

Introduction The following study aimed to find the pooled prevalence estimate of anatomical
variations in the palmar vasculature, namely the superficial palmar arch (SPA) and the deep …

The vascular anatomy of the hand is a complex and challenging area and has been the
subject of many studies. Knowledge of the vascular patterns and diameters of the hand …

The median artery has been considered as an embryonic structure, which normally
regresses around the 8th week of gestation. However, various prevalences have been …

The presence of a persistent median artery (PMA) has been implicated in the development
of compression neuropathies and surgical complications. Due to the large variability in the …

Objectives: to describe the radial artery and its variants in origin, branching pattern, mode of
termination, measurements of its length and external diameter. Methods: 100 upper limbs of …

Diabetes has become a major health problem in society. Invasive glucometers, although
precise, only provide discrete measurements at specific times and are unsuitable for long …
