We treated a VKCFD patient with subarachnoid hemorrhage, with favorable outcomes.METHODS： A 19-year-old male student with VKCFD was treated at our hospital. The initial treatment was injection of a large dose of vitamin K and fresh plasma, and then with oral high dose of vitamin K4.RESULTS： At 4 weeks after admission, the focus of hemorrhage subsided, neurological examination was normal, and the patient was discharged.CONCLUSIONS： VKCFD is rare and its diagnosis should be based on the history of the patient and the results of laboratory examinations. A large dose of vitamin K is the fi rst choice of treatment.展开更多

We have performed investigations in anesthetized Sprague-Dawley rats- Intracisternal injection (i. c. ) of ET-l (10-11, 10-10, 10-9 mol/kg) could induce acute dose-dependent CVS, furthermore, the highest dose of ET-l (lO-’ mo1/kg) had a biphasic response in CVS of a 24-hour duration. However, the CVS by ET-1 (10-9 mol/kg) could be prevented effectively by previous i. c. of BQ-123 in a dose-dependent manner (10-9, 10-8, 10-7 mol/kg), of which the i. c- of BQ-123 (10-7mol/kg) could abolish the CVS completely. i. c. of BQ-123 (10-7 mol/kg) before SAH induced by a single i. c, of 150 pl autologous fresh blood directly to the Willis circle cou1d prevent the following CVS largely, which was a biphasic response and long-lasting (duration of 72 h). We conclude that subarachnoid application of ETA-receptor antagonist can effecti vely prevent CVS induced by ET-1 and SAH, and ET-1 may be the major mediator responsible for the CVS following SAH.展开更多
