📖 Overview
Splenic embolization uses a catheter advanced through the femoral artery to the splenic artery, with injection of embolic agents to reduce splenic blood flow. Partial embolization (40–60% of the spleen) reduces splenic sequestration of blood cells in hypersplenism while preserving immune function. Total embolization (pre-operatively) or splenic artery aneurysm treatment are other indications.
🎯 Indications
- Hypersplenism with thrombocytopenia or anaemia — pre-chemotherapy or ongoing haematological disease
- Portal hypertension — reducing splenic congestion and platelet sequestration
- Splenic artery aneurysm — endovascular treatment
- Pre-operative embolization before splenectomy — reduce intra-operative blood loss
