Abstract:
Objective:To summarize the clinical features, treatment and prognosis of asparaginase (ASP) related cerebral venous sinus thrombosis (CVST).Methods:Clinical profiles including age, sex, first symptoms, coagulation function, imaging findings, ASP type, treatment and prognosis of eight acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL) children with ASP related CVST at the Department of Pediatrics, First Affiliated Hospital of Zhengzhou University from November 2016 to October 2021 were analyzed retrospectively.Results:Eight CVST children were all male, including 6 ALL and 2 LBL, with the onset age ranged from 5 to 15 years, 6 cases occurred in the stage of first induction remission, and the initial symptom were mainly epileptic seizures (7 cases). Magnetic resonance imaging combined magnetic resonance venography (MRV) showed the most common site of venous sinus enlargement was superior sagittal sinus (8 cases). Secondary cerebral hemorrhage was found in 5 cases. D-dimer elevated on the day of onset in all cases. Three patients were treated with intravascular mechanical thrombectomy and thrombolysis combined with anticoagulant therapy, 3 patients were treated with continuous anticoagulant therapy only, 2 patients were not treated with anticoagulant therapy. MRV follow-up for 3 months showed that the thrombi in patients were almost completely absorbed except in 2 patients who were not treated with anticoagulant therapy. Thrombolysis combined with anticoagulant therapy was the fastest way for thrombosis absorption. Among 8 patients, 1 died of early recurrence of ALL, and 7 patients accepted further asparaginase and no CVST recurrence or progression was found. There were no sequelae of nervous system except 1 patient with left upper limb muscle strength impairment.Conclusions:ASP related CVST is more common in older male children and the prognosis is good. ASP related CVST occurred mostly in the stage of first induction remission, and most initial manifestation is epileptic seizure. The superior sagittal region is a common site of thrombus, magnetic resonance imaging combined with MRV is helpful for accurately diagnosis. Timely anticoagulant treatment can improve the prognosis, and mechanical thrombectomy and thrombolysis can quickly recanalize the vessel.
