Circulatory failure following surgery for type A aortic dissection is frequent and associated with a high mortality rate. The intra-aortic balloon pump (IABP) is used to treat postcardiotomy cardiogenic shock but aortic dissection is traditionally a contraindication. In 10 patients we used IABP for severe cardiogenic shock following aortic dissection surgery, here we report on the short and midterm results. ⋯ IABP should only be used as a salvage option in cases of severe cardiogenic shock following type A aortic dissection. No patient suffered device-related aortic rupture or extension of the dissection. High mortality and morbidity underline the gravity of cardiogenic shock in this setting.

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.

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.

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.

Acute type B aortic dissection is a life threatening disease process, which remains a clinical dilemma despite advances in technology, surgical technique and postoperative management. The variability of presenting symptoms, lack of a consensus on indications for treatment and differing opinions about the optimal timing for repair have added to the management confusion. Medical management has been the standard of care for acute uncomplicated type B dissection. ⋯ Recent data suggest that early TEVAR lowers aortic-related events and improves long-term aortic specific survival by covering the entry tear, promoting false lumen thrombosis and inducing aortic wall remodeling. The paucity of supporting data has created controversy surrounding the optimal treatment strategy for acute type B dissection. Nonetheless, recent healthcare trends show a paradigm shift towards the utilization of early TEVAR in acute type B dissection.
