The position of the aortic bifurcation in women in relation to the lumbar vertebral bodies was determined in 100 pelvic arteriograms to provide some help in teleradiation therapy planning for pelvic malignancies. It was found that in order to cover the area of the aortic bifurcation, the radiation field should extend to the top of the body of the fourth lumbar vertebra.

Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is an unwarranted complication associated with high mortality. The current TAVI practices recommend a multidetector computed tomography (MDCT) evaluation of the aortic valve, the left ventricular outflow tract, and the aortic root to determine the conventional risk factors for coronary obstruction like low-lying coronary ostia and narrow sinuses of Valsalva, mandating prophylactic coronary protection or native valve leaflet modification in high-risk patients. Despite optimal anatomy, acute coronary occlusion can still occur due to multiple mechanisms, one of which is coronary embolism due to thrombus, calcium, or native aortic valve fragments.

A 24-day-old female Japanese Black calf presented a sudden paraplegia after a history of watery diarrhea. Antemortem magnetic resonance imaging confirmed the suspicion of thrombotic component in the abdominal aorta, without any spinal cord abnormality at the lumbar region. On necropsy, a massive thrombus occupied the lumen from the distal abdominal aorta to the bifurcation of the external iliac arteries.

Peripheral arterial chemoreceptors monitor the levels of arterial blood gases and adjust ventilation and perfusion to meet metabolic demands. These chemoreceptors are present in all vertebrates studied to date but have not been described fully in reptiles other than turtles. The goals of this study were to 1) identify functional chemosensory areas in the South American rattlesnake (Crotalus durissus) 2) determine the neurochemical content of putative chemosensory cells in these areas and 3) determine the role each area plays in ventilatory and cardiovascular control.
