Case Reports[A case of total arch replacement for traumatic aortic arch rupture].
We report a case of aortic arch rupture due to blunt chest trauma. A 64-year-old woman was crushed under a wood when she was working. On her arrival to our hospital, she was in shock state due to cardiac tamponade. ⋯ As the intimal disruption was found to be extended to three fourths of the circumference of aortic arch, total arch replacement was performed. In this case, the TEE was useful for the immediate diagnosis of the aortic rupture. This was the first successful case of total arch replacement for a traumatic arch rupture.

Randomized Controlled Trial Clinical Trial[Clinical evaluation of heparin concentration and activated clotting time monitoring (HEPCON HMS) system].
The HEPCON HMS system provides both activated clotting time (ACT) and accurate whole blood heparin concentration measurements. We evaluated the impact of heparin and protamine administration using this system on the incidence and treatment of bleeding after performing a cardiopulmonary bypass. Patients were randomly divided into two groups. ⋯ There were no statistical differences in the coagulation factor, the postoperative chest tube drainage or the blood products used between the two groups. Patients in Group H received a higher dosage of heparin and a lower dosage of protamine compared with Group A. By facilitating the maintenance of a therapeutic heparin concentration and by determining an appropriate protamine dosage, the HEPCON HMS system may be useful in managing extracorporeal circulation.
