Aim of the paper was to assess the reliability of preoperative cross-flow determination by transcranial Doppler measurement (TCD) to detect clamping ischemia in patients undergoing carotid endarterectomy with selective shunting. ⋯ TCD scanning is highly reliable to detect cross-flow prior to carotid surgery and thus helpful to identify patients at risk for clamping ischemia and need for shunting.

Comparative Study
On or off pump coronary bypass? Insight from matched and principal component analyses of 8779 operations.
The aim of this paper was to compare the clinical impact of the different myocardial protection strategies in coronary artery bypass grafting (CABG) patients to facilitate decision-making for use of on- or off-pump technique. ⋯ Comparatively, on-pump techniques were associated with greater risk of adverse events in "high risk" patients defined by clinical characteristics, while off-pump was associated with increased risk of adverse events in "low risk" patients.

He aim of this paper was to investigate the incidence of and the indications for conversion to general anesthesia (GA) in a large single-center series of patients undergoing carotid surgery under cervical plexus block (CPB). ⋯ Cervical plexus block for carotid surgery is associated with a low rate of conversions to GA. Neurological deterioration upon carotid clamping and local anesthetic toxicity are identified as the most common indications for such intervention.
