Photogrammetric Reconstruction of 3D Human Anatomical Structures and Augmented Reality via Smartphone Technology

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Limited access to cadavers necessitates the availability of digital resources for anatomy education. Smartphone‐based photogrammetry offers a promising solution for creating three‐dimensional (3D) and augmented reality (AR) models. This study compared two mobile photogrammetry applications (Qlone and Polycam) that have been used in modern ...

The Impact of Aging on the Anatomical Course of the Azygos Vein: A Retrospective, Computed Tomography Study

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The azygos vein (AV) is typically described as ascending vertically to the right of the vertebral column before arching anteriorly to drain into the superior vena cava. However, a small number of studies suggest that it is found leftward in older adults.

Congenital Absence of Superior Vena Cava with no Manifestation of Superior Vena Cava Syndrome [PDF]

open access: yesKorean Circulation Journal, 2016
Total absence of superior vena cava (SVC) is a very rare anomaly, and the patient usually suffers from SVC syndrome or conduction disturbances. We report an asymptomatic 27 year-old male, with complete absence of SVC. Transthoracic echocardiography and computed tomography demonstrated the absence of SVC and other congenital cardiac anomalies, but the ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Malposition of a Port Catheter in the Azygos Vein: Endovascular Repositioning Using a Long Loop Snare Technique

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Port catheters provide a reliable, long‐term venous access option in children for repeated administration of medications or parenteral nutrition. A cardiac catheterization procedure was performed in a 7‐year‐old girl in whom lateral chest radiography revealed posterior deviation suggestive of azygos vein malposition.
