Variation of Cognitive Function During a Short Stay at Hypobaric Hypoxia Chamber (Altitude: 3842 M).

Objective: To observe the effects of a fast-acute ascent to high altitude on brain cognitive function and transcranial doppler parameters in order to understand the physiological countermeasures of hypoxia.

Methods: 17 high-altitude-naïve male subjects (mean age was 26.3 ± 8.

Tube graft replacement of the suprarenal aorta with implantation of the superior mesenteric artery.

The superior mesenteric artery was successfully implanted to a tube graft replacement of the suprarenal abdominal aorta after a gunshot wound. Although injuries to the abdominal aorta carry a high mortality, adequate management and prompt operation can reduce the mortality rate. In cases like this one the ingenuity of the surgeon is at stake, because arterial anastomoses are not always possible to their natural origin.
