Absolute contraindications to percutaneous tracheostomy due to anomaly of aortic arch branches origin and running A 77-year-old patient required percutaneous tracheost-omy. A first clinical evaluation showed a pulsating mass in the suprasternal region. Computed tomography (CT) revealed the presence of anomaly of the aortic arch branches (Fig. 1). We did not perform any type of tracheostomy due ...
Power-line networks are widely used today for broadband data transmission. However, due to multipaths within the broadband power line communication (BPLC) systems owing to stochastic changes in the network load impedances, branches, etc., network or channel capacity performances are affected. This paper attempts to investigate the performance of typical medium voltage channels that uses Orthogo...
The relative noninvasive nature, easy accessibility, convenience and accuracy of helical CT in the rapid evaluation of not only the aorta and its branches, but the entire thorax/abdomen, makes it the best suited imaging modality for use in evaluation of aortic aneurysms and dissection. Excellent vascular opacification, the advantage of reconstructing overlapping scans without respiratory misreg...
