Partial splenic embolization in a child with Gaucher disease, massive splenomegaly and severe thrombocytopenia.

A 13-month-old boy with Gaucher disease presented with severe thrombocytopenia, anemia and massive splenomegaly. In addition he had significant respiratory compromise caused by abdominal compartment syndrome, requiring mechanical ventilation. Because of the degree of respiratory compromise and his existing bone marrow suppression, splenic artery embolization was chosen as an alternative to splenectomy. Splenic artery embolization was performed using 355-500-microm polyvinyl alcohol particles, with 70% ablation achieved. Within 24 h of the procedure the platelet count had risen to greater than 70,000/mm(3) and to more than 170,000/mm(3) on postoperative day 4. At the 8-month follow-up the splenic size had decreased from 18 cm to 8 cm, with a platelet count of 578,000/mm(3). Partial splenic embolization provides a minimally invasive alternative to splenectomy in patients with Gaucher disease with massive splenomegaly and bone marrow suppression.
