Dynamics of homemade aortic endografts: in vivo study in humans with computed tomography scanner modeling.

Background: Several cases of aortic endograft rupture have been described. In most cases, they stem from component wear and perforation of the graft, leading to leakage. Friction of the stents on the graft can cause abrasion and perforate the textile.

[Pseudoaneurysm of the deep palmar arch due to infective endocarditis].

The authors report a case of mycotic pseudoaneurysm of the deep palmar arch in a complicated case of Staphylococcus aureus infective endocarditis. They review the literature to discuss the physiopathology, diagnosis and treatment of this rare complication.

Chronology of the push pull effect on nonhuman primates-shift of the arterial pressure threshold.

Fighter pilots are frequently exposed to high Gz acceleration which may induce in-flight loss of consciousness (G-LOC). One factor reducing tolerance to accelerations is a previous exposure to negative accelerations. This phenomenon, which happens during the first few seconds after the onset of the positive plateau, is called the push pull effect.

Static mechanical properties of custom-made aortic endografts.

Several cases of delayed aortic rupture after endovascular aneurysm repair have been attributed to in vivo endograft fatigue. Such complications could involve damage to structural components during introduction. The purpose of this study was to compare forces applied during introduction to forces needed to damage the endograft.
