In a final step, the measurements were calibrated to the patient's body size, as the length of the abdominal aorta between the origin of the celiac trunk and the bifurcation is proportional to body size.
Axial CT image shows the presence of hypodense soft tissue (white arrow) consistent with tumour recurrence, encasing the origin of the caeliac trunk and portal vein Open image in new window Fig. 29 Nodal tumour recurrence.
Alternatively, a right brachial approach can be used to insert the device if no other peripheral access is available, but this approach may be associated with neurological complications related to crossing the origin of the innominate trunk.
Genetic fate-mapping studies using the neuroepithelial marker Sox1 identified a neuroectodermal origin of the earliest trunk MSCs, but other MSCs are recruited from undefined sources at later stages (Takashima et al., 2007).
The atherosclerotic burden was quantified at a defined segment of the abdominal aorta between the origin of the celiac trunk and the bifurcation using a method also suitable for volume data sets acquired by helical scanning from CTs not designed for calcium scoring [ 21].
More important, however, than this strict definition issue, we discuss what these new data imply for the origin of the pygidium, i.e. that it may share a common evolutionary origin with the trunk segments.
The single clonal origin of the precursor cells for the trunk SE contrasts with the double clonal origin of the precursor cells for the head SE and for the SE of the posterior part of the embryo.
The origin of trunk neural crest from the neural ectoderm was unequivocally shown through grafting of neural tube in avian embryos (Weston, 1963).
In this group of patients en bloc lymph node dissection was performed, including the paraesophageal, sub carinal, posterior mediastinal and paracardial lymph nodes, as well as those located along the lesser gastric curvature, the origin of the left gastric artery, the celiac trunk, the common hepatic artery and the splenic artery.
