Capillary leak syndrome (CLS) represents a critical complication arising from allogeneic hematopoietic stem cell transplantation (allo-HSCT). The prognosis for CLS remains considerably constrained. A targeted therapeutic approach targeting vascular endothelial growth factor (VEGF) offers a novel strategy for the management of CLS.
