The purpose of this study is to compare the hemodynamics effects of two usual hypnotic agents (LENOXe ™ (xenon 100 % v/v) and sevoflurane) during a general anesthesia for carotid endarterectomy in elderly patients. The hypothesis is that the use of the LENOXe ™ (xenon 100 % v/v) allows to obtain per-operating hemodynamic stability non inferior than with sevoflurane.

Primary Outcome Measures:
  • Standard deviation of the values of systolic blood pressure (SBP)collected per-operatively every minutes(BIOPAC ® MP150) Values of SBP over or under thresholds during and out of the clamping period, if so vasopressive/ hypotensive treatment used [ Time Frame: Pre-op, every min from 1-90 min during maintenance phase ]

Secondary Outcome Measures:
  • cardiovascular, general, hepatic and renal tolerance to xenon. Quality and time of awakening, recovery index (IR);Post-op pain (EVA)and consumption of analgesic; Inflammatory Syndrome (cytokine profile); Subjective comfort of the patient [ Time Frame: During the whole anesthetic procedure and the postoperating time until 24 hours after discharge from the recovery room / intensive care unit and return to the ward ]

Estimated Enrollment: 84
Study Start Date: July 2009
Study Completion Date: April 2010
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
