conclusions in our conditions, the use of an anatomical landmark-guided procedure was the preferred treatment method due to limited resources and a lack of adequate training. background central venous cannulation is a current and important procedure used in the operating room and intensive care unit. some studies have shown that the application of ultrasound-guided cannulation can improve the s...

Over the last ten years, transradial cardiac catheterization has been increasingly applied, primarily because of its lower incidence of complications compared to the femoral approach. However, one of the greatest flaws of the transradial approach is a relatively high incidence of catheterization failure (1%-5%). Anatomic variations of radial artery are ranked second among the reasons for this. ...

PURPOSE To assess the influence of anatomic location on the relationship between computed tomography (CT) number and X-ray attenuation in limited and medium field-of-view (FOV) scans. MATERIALS AND METHODS Tubes containing solutions with different concentrations of K2HPO4 were placed in the tooth sockets of a human head phantom. Cone-beam computed tomography (CBCT) scans were acquired, and CT...

Non-recurrent inferior laryngeal nerve (ILN) arising from the vagus nerve is a rare anatomic variation. The vagus descends vertically in the cervical neurovascular bundle, between and posterior to common carotid artery (CCA) and internal jugular vein (IJV). The vagus has also some anatomic variations. We present a case of two coincident anatomic variations both ILN and the vagus nerve. A patien...

BACKGROUND Understanding the hemodynamics of the total cavopulmonary connection may lead to further optimization of the connection design and surgical planning, which in turn may lead to improved surgical outcome. Although most experimental and numerical investigations have mainly focused on somewhat simplified geometries, investigation of the flow field of true anatomic configurations is neces...
