520 |a Objective: To investigate the clinical characteristics and prognosis of children with acute promyelocytic leukemia (APL) complicated with thrombosis. Methods: The clinical profiles of four APL patients complicated with thrombosis treated at the First Affiliated Hospital of Zhengzhou University between January 2012 and December 2019 were reviewed. Literature search and review covered the China national knowledge infrastructure, Wanfang database, China biology medicine disc and PubMed using the key words of "acute promyelocytic leukemia" and "thrombosis" up to June 2020. Results: Four patients included one male and three females with an age range of 4-13 years. In two patients, thrombosis occurred intracranially, both patients presented with seizure and hemiplegia. In one patient, thrombosis occurred in spleen, the patient presented with severe abdominal pain. In the last patient, thrombosis occurred in liver, the patient presented with abdominal pain, distension and ascites. Thrombosis occurred during the course of retinoic acid treatment in three patients, it occurred before the initiation of the treatment in one patient. Thrombosis was confirmed by imaging examination in all four patients. After thrombolytic and anticoagulation treatment, the vessels were recanalized and the symptoms were alleviated in 3 cases, the fourth patient died of hepatic venous thrombosis. Literature search identified no similar reports in Chinese journals, 11 case reports were found in English journals. In these 15 patients, 9 were male and 6 females with an age range of 3-16 years. Thrombus located in brain in 6 cases, in lower limbs for 3 cases, in liver for 3 cases, in spleen in 2 cases and in coronary artery for 1 case. In 10 cases thrombosis occurred before the induce treatment and in 5 cases occurred during the induction treatment. After surgery, thrombolytic and anticoagulation treatment vascular recanalization was observed in 10 patients, and in those patients, the symptoms were relieved, death occurred in 5 patients, including three patients with hepatic venous thrombosis. Conclusions: Thrombosis may occur before or during the treatment for APL. Both arterial and venous thrombosis may occur in patients with APL. Imaging examination is a reliable method for its diagnosis. After treatment, most patients had good prognosis with recanalization of blood vessels, but the mortality rate was high for patients with hepatic venous thrombosis
