The precipitating factors included prolonged labor (n = 3), birth trauma (n = 2), breech (n = 1), wandering spleen (n = 1), assaulted before delivery (n = 1), post resuscitation (n = 5), congenital deficiency in coagulation factor VII deficiency (n = 1), erythroblastosis fetalis (n = 4), hemophilia A (n = 3), family history of hemophilia A (n = 1), and preterm neonate (n = 11).
