Abstract | BACKGROUND: METHODS: We described five rare cases of patients with HIT associated with deep vein thrombosis treated with dabigatran, a member of NOACs. We also reviewed representative cases and literature investigating the use of NOACs to treat patients with HIT to further discuss the efficacy and safety. RESULTS AND CONCLUSIONS: Following the treatment of dabigatran after argatroban, the platelet count of patients with HIT gradually elevated and reached the normal range eventually. There was no incidence of new symptomatic, objectively-confirmed arteriovenous thromboembolism observed within the 90-day-period follow up. The patient in case 3 presented with gastric bleeding after dabigatran treatment and died in the end. The results suggested that dabigatran use after argatroban may be effective in the treatment of patients with HIT. However, safety should be reconsidered since severe complications were observed in case 3.
