Immediate Transfer for Clot Extraction in a Young Woman With Leukemia and Asparaginase-Associated Acute Cerebral Vein...

We present the case of an 18-year-old woman with B-cell acute lymphoblastic leukemia (ALL) who developed hemorrhagic stroke and epilepsia partialis continua due to acute cerebral vein thrombosis (CVT). The patient had 10 risk factors for CVT (including use of asparaginase chemotherapy for the ALL) and also unfortunately had 4 biomarkers for poor prognosis for outcome post-CVT diagnosis. Immediate transfer to a Comprehensive Stroke Center allowed for hyperacute neurointerventional clot extraction with rapid restoration of the patency of the superior sagittal sinus. This resulted in an unexpectedly favorable neurological outcome and simultaneously allowed for early resumption of chemotherapy for ALL after only a 5-day hiatus. Our case highlights the importance of immediate transfer of highest risk patients with multiple biomarkers for poor prognosis to a Comprehensive Stroke Center with endovascular and neurosurgical capabilities and the possibility of overcoming the odds of a poor outcome with venous clot extraction if medical management fails. Neurological deterioration due to escalating intracranial pressure with impending herniation may occur rapidly, and treatment at such facilities can be life-saving.
