Forty-nine patients with the occlusive lesions of the thoraco-abdominal aortic segment, congenital hypoplasia (13 patients) and non-specific aortitis (36 patients) were operated on. Operations were performed under moderate hypothermia (+30-31 degrees C) through the left thoracophrenolumbotomic approach. In the majority of patients reconstruction of the aorta was done by means of its resection and replacement. In 9 patients with congenital hypoplasia we performed aortic reconstruction only, and in 4 it was combined with plastic procedure on the coeliac trunk. In 25 patients with non-specific aorto-arteritis aortic replacement was combined with revascularization of the visceral (renal) arteries. In this group reconstruction of the aorta and visceral branches was performed in 7 cases, that of the aorta and renal arteries in 62 and simultaneous reconstruction of the aorta, visceral and renal arteries in 16 cases. Total mortality was 6.1% (3 patients). There was no mortality in patients with aortic hypoplasia.

Cephalic fluid shifts, induced by lower body positive pressure (LBPP) are known to influence various physiological systems (i.e. cardiovascular and renal). In earlier experiments, we observed an apparent change in the arousal state of primates in such LBPP conditions. This study was designed to examine the effects of LBPP on arousal state and body temperature level which is normally correlated with sleep. Chair restrained male squirrel monkeys were exposed to 40 mmHg LBPP for 90-100 minutes between the daytime hours of 13:00-15:00. Each monkey was placed in a specially modified restraint chair to which they were highly restrained [correction of trained]. Deep body temperature (DBT) was collected from 10 animals. Sleep parameters were obtained from 6 animals chronically implanted for sleep recording. A video camera was used to observe each animal's apparent state of arousal. LBPP resulted in an approximate 0.9 degree C decrease in DBT. During video observation some animals appeared drowsy during LBPP, however, sleep recording revealed no significant changes in the state of arousal. Thus, LBPP is capable of inducing a mild hypothermia [correction of hyperthermia]. Further, the mechanisms underlying the observed lowering of body temperature appear to be independent of arousal state.
