Alternative to splenectomy
In cirrhosis, the enlarged spleen “absorbs” platelets - their deficiency blocks treatment and threatens bleeding; partial embolization (50–70% of the parenchyma) solves the problem minimally invasively: platelets grow in the first weeks and the effect lasts for years, while the immune function of the organ is partially preserved - important for the prevention of infections. The stage and volume are determined by angiography. Post-embolization syndrome (pain, temperature) is controlled for 2–5 days; prevention by vaccination and antibiotics - according to the protocol.
Indications
- uterine fibroids with bleeding in women who want to avoid surgery or preserve the uterus (UA);
- fibroids before myomectomy to reduce blood loss;
- hypersplenism in cirrhosis (thrombocytopenia) - partial embolization of the splenic artery;
- preparation for operations on the spleen, some bleeding.
How embolization works
Targeted closure of the arteries deprives the pathological focus of blood supply: myomatous nodes after UAE are reduced by 40–60% in six months, bleeding stops from the first cycle, the uterus and fertility are preserved; with partial embolization of the spleen, the sequestration of blood cells decreases - platelets grow without removing the organ. The procedure is performed through a 2–3 mm puncture without anesthesia; post-embolization syndrome is typical (pain, fever for 1–3 days), relieved with drugs.
