Abstract
Recombinant factor Vila (rFVIIa; NovoSevenTM) was available for compassionate use in Australia and New Zealand from 1991 to 1994. Over this period there were 18 treatment episodes in 9 patients, age 8-66 years, with haemophilia A and high titre inhibitors cross-reacting with porcine factor VIII. There were no significant adverse effects. Treatment with rFVIIa resulted in a successful outcome in 8 potentially life-threatening (retroperitoneal, subdural, gastro-intestinal) bleeds. Elective cystoscopy, repair of a cranial flap, yttrium synovectomy and inguinal herniotomy were performed successfully, as was surgical decompression of a flexor pollicis longus bleed. Treatment of a patient with an infected haematoma had limited success, attributed to intermittent suboptimal doses. In 2 patients, satisfactory haemostasis was achieved for multiple dental extractions; subsequent oozing was attributed to suboptimal rFVIIa and/or antifibrinolytic therapy.
