Abstract Introduction Carotid artery dissection is a common cause of stroke in the young. It has been related to association carotid with fixed neighbouring anatomical structures. This study assesses between styloid process length, internal position and cervical (CCAD). information would provide potential predicative radiological measurements, which could prevent delays CCAD diagnosis. Method R...

A 3D-dissection (A rectangular solid dissection) is a dissection of a rectangular solid into smaller rectangular solids by planes. In this paper, we propose an O-sequence, a string of representing any 3Ddissection which is dissected by only non-crossing rectangular planes. We also present a necessary and sufficient condition for a given string to be an O-sequence. key words: rectangular solid d...

The diagnostic value of a combination of transoesophageal and transthoracic echocardiography was evaluated in 21 patients with dissection of the aorta. The results were compared with those of computed tomography, aortography, and with findings at operation or necropsy or both. Transthoracic echocardiography identified three of the four patients with type I dissection, two of the five patients w...
