RESUMO
WHAT IS KNOWN AND OBJECTIVE: Peripheral vascular adverse events have been reported with ponatinib treatment in chronic myeloid leukaemia (CML) after failure of dasatinib or nilotinib. We here report peripheral arterial occlusive disease (PAOD) in a patient who had previously received only imatinib as tyrosine kinase inhibitor. CASE DESCRIPTION: The patient was a 70-year-old man with no history of cardiovascular disease. He developed arterial hypertension 5 months after the initiation of ponatinib and PAOD 41 months later. WHAT IS NEW AND CONCLUSION: Peripheral arterial occlusive disease can occur several years after the initiation of ponatinib in patients who had previously received only imatinib. Long-term surveillance is required for preventing the complications of ponatinib-associated PAOD.
