What is leukostasis?

Intravascular accumulation of white blood cells (WBCs) causing obstruction of blood flow in patients with hyperleukocytosis (defined as WBC count >100 x 10⁹/L), especially those with acute leukemia, in which the white cells are “stickier” compared to reactive causes or those with chronic lymphocytic leukemia (CLL). May lead to organ compromise. Learn more here.
