Article Synopsis
- Carotid artery disease is common in patients with coronary heart disease, requiring revascularization options that include simultaneous or staged surgeries for treatment.
- A study involving 192 patients compared the outcomes of simultaneous coronary artery bypass grafting (CABG) and carotid endarterectomy (CEA) versus staged procedures, assessing their 30-day and long-term effects on overall health.
- Results showed no significant differences in short-term and long-term major cardiovascular events between the two groups, but the simultaneous surgery group had a higher risk of complications and required longer ventilatory support, despite not leading to more deaths or major adverse events.

Objective: Operation for aortic recoarctation and/or residual hypoplastic arch represents a surgical challenge because of surrounding scar tissue in the coarctation area, hazard of spinal cord ischemia due to aortic cross-clamping, laceration of the recurrent nerve, and the choice of the best approach. We demonstrate the results of 52 operations of an extra anatomically bypass technique via right thoracotomy approach without establishment of cardiopulmonary bypass.
Methods: Since 1987, 52 patients underwent extra anatomically positioned ascending-descending bypass grafting.
In this work the thermal properties of diethyl sulphoxide (Et2SO), as well as its cryoprotective ability are studied and related to other well-known cryoprotectant substances, like dimethyl sulphoxide (Me2SO). We have investigated the thermal properties of Et2SO/water systems using Differential Scanning Calorimetry at a very low heating/cooling rate (2 degrees C/min). Liquid/solid or glassy/crystalline transitions have been observed only for the solutions with content of Et2SO ranging from 5 up to 40% w/w and/or greater than 85%.
