Thirty-five patients hospitalized for recent angiographically documented arterial occlusion in the legs (27 femoropopliteal arteries and eight grafts) benefited from local fibrinolytic therapy delivered at the site of the occlusion with a 4- or 5-F catheter. This therapy combined a continuous urokinase (UK) infusion of 1,000 U/kg/hour and a lysyl plasminogen (LYS-PLG) infusion of 15 microkatals every 30 minutes. Angiographically confirmed lysis was obtained in 85% of the cases. Only 3% of the patients had major and 6% had minor groin hematomas. Only two patients had concentrations of fibrinogen as low as 100 mg/dl. Intravascular infusion of UK-LYS-PLG is as effective as streptokinase. Its excellent tolerance makes it a good alternative in the treatment of acute ischemia in the lower limbs. 相似文献

Stroke is a major health problem worldwide, causing high morbidity and mortality. Intracerebral hemorrhage (ICH) accounts for 15% of stroke cases in the US and Europe and up to 30% in Asian populations. It is less treatable than other forms of stroke and causes higher morbidity and disability. Data suggest that early hematomy growth is the principal cause of early neurological deterioration after ICH. Prospective and retrospective studies indicate that early hematoma growth occurs in 18–38% of patients scanned within 3 h of ICH onset, and that hematoma volume is an important predictor of 30-day mortality. As hematoma growth in acute ICH is a dynamic process, intervention with ultra-early hemostatic therapy could lead to minimization and even prevention of early hematomy growth. Recombinant activated factor VII (rFVIIa, ‘NovoSeven’), a powerful initiator of hemostasis, is approved for the treatment of bleeding in patients with hemophilia and inhibitors and may also promote hemostasis in patients with normal coagulation. rFVa acts locally at the bleeding site without activating systemic coagulation and may be a valuable therapy during the hyperacute stage of ICH. A randomized, double-blind, placebo-controlled, dose-ranging trial is currently in progress to investigate the potential of rFVIIa as an ultra-early hemostatic therapy to prevent or minimize hematoma growth in ICH patients without coagulopathy. 相似文献

Erythromycin-Induced Immune Hemolytic Anemia 总被引:2,自引:0,他引:2

A 3-year-old female receiving Pediazole (erythromycin ethylsuccinate and sulfisoxazole) for tonsillitis and otitis media developed severe hemolytic anemia. No serum drug-dependent antibodies could be demonstrated with an in vitro 'immune-complex' method using Pediazole, pure erythromycin ethylsuccinate or pure sulfisoxazole. However, a method using red cells coated with erythromycin base showed in vitro lysis of the erythromycin-coated red cells. This is only the second case of immune hemolytic anemia associated with erythromycin and the first where in vitro drug-dependent hemolysis was demonstrable. 相似文献
