Comparison of ascending aortic cohesion between patients with bicuspid aortic valve stenosis and regurgitation.

Objectives: A bicuspid aortic valve (BAV) is commonly associated with aortic wall abnormalities, including dilatation of the ascending aorta and increased potential for aortic dissection. We compared the mechanical properties of the aortic wall of BAV patients with aortic valve stenosis (AS) and regurgitation (AR) using a dissectometer, a device mimicking transverse aortic wall shear stress.

Methods: Between March 2010 and February 2013, 85 consecutive patients with bicuspid aortic valve undergoing open aortic valve replacement at our institution were prospectively enrolled, presenting either with stenosis (Group 1, n = 58) or regurgitation (Group 2, n = 27).

[Secondary omentitis in children following appendectomy].

The data on treatment of 18 children with secondary omentitis, which developed after appendectomy, are presented. A complication can manifest itself as an abscess of the omentum and as its infiltration, differing in clinical picture and the findings of electromyography. On the basis of the analysis of 463 appendectomies, at the time of which the changes in the omentum were revealed, the association of the form of appendicitis and secondary omentitis is shown.
