Trombosis en LAM3 (i) mere coincidence (e.g. genetic predisposition, prolonged bed rest or immobility) (ii) causation by APL (iii) causation by all-trans retinoic acid (ATRA) (iv) causation by the combination of ATRA and antifibrinolytic agents (v) as a part of the differentiation syndrome caused by ATRA (i.e. ATRA syndrome) Rashidi A.

Guidelines for the treatment of coagulopathy in APL patients
Initiate ATRA as soon as the diagnosis is suspected based on the clinical picture and morphologic findings in the peripheral blood without waiting for cytogenetic or molecular genetic confirmation Aggressive platelet support to maintain the platelet counts greater than 30,000–50,000/mL Aggressive repletion of fibrinogen with cryoprecipitate to maintain with fibrinogen greater than 150 mg/dL No routine use of heparin No routine use of antifibrinolytic agents Start treatment of the disease with ATRA and chemotherapy for patients who present with a high white blood cell count
