Do the evaluation of intra- and extra-cranial circulation in subclavian steal syndrome?
Reversal flow of the vertebral artery may occur in rest or only in exercise, depending on the grade of subclavian arterial stenosis. Hyperemia test is the most sensitive index. It is necessary to monitor blood flow in the MCA and basilar artery in hyperemia test. The coexistence of intra- and extra-cranial arterial stenosis is common.
This study is the first to investigate eight hours of capnoperitoneum in a survival model. GIT-TT is not affected by prolonged capnoperitoneum in pigs. No POI occurred with prolonged capnoperitoneum. Prolonged capnoperitoneum is safe regarding postoperative gastrointestinal function in innovative surgical procedures.
