Review Case Reports[Coarctation of aorta with right aortic arch and anomalous left subclavian artery].
The occurrence of coarctation in patients with right aortic arch is extremely rare. We have encountered a 21-year-old man with anomalous left subclavian artery. He was diagnosed when he was 13. ⋯ Clinical studies revealed no vascular ring and no other anomalies were found in this patient. An attempt at treatment was made with extra anatomical bypass grafting from the ascending aorta to the descending aorta. No pressure difference due to coarctation remained after operation.

[Reinfusion of autologous platelet-rich plasma improves hemostasis after cardiopulmonary bypass].
Although it is reported that postoperative bleeding is reduced by reinfusing autologous platelet-rich plasma (PRP) after cardiopulmonary bypass (CPB), the effect of PRP on hemostasis is not reported in detail. We prepared PRP and fresh whole blood (WB) from the blood of seven patients each prior to their undergoing CPB, and reinfused them autologously to the patients intravenously after the CPB was terminated. In this article, the effect on hemostasis of autologous PRP and WB was described. ⋯ The platelet counts increased from 4.3 +/- 1.4 x 10(4)/mm3 to 14.1 +/- 1.6 x 10(4)/mm3 after PRP reinfusion and the platelet aggregation rates increased significantly (p less than 0.01) after PRP reinfusion compared to WB transfusion. The activities of coagulation factors VII-X also increased significantly (p less than 0.05) after reinfusion of PRP when compared to transfusion of WB. The activated partial thromboplastin time decreased to 1.2 times the baseline in the PRP group but remained 1.5 times the baseline in the WB group (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
