France: Medical Breakthrough with Treatment for Rare Vascular Tumor in Embryo

In France, a groundbreaking treatment was administered to an embryo suffering from the rare Kasabach-Merritt syndrome, a vascular tumor threatening its life. The diagnosis was made during the seventh month of pregnancy, and the tumor was growing rapidly, covering most of the embryo's face. The treatment involved administering Sirolimus to the mother, aiming to inhibit angiogenesis and tumor growth. Isa was born via Cesarean section with a significantly reduced tumor and did not require intubation. Despite the presence of a tumor on the lower part of his face, the baby is healthy and developing normally, while the treatment continues. This successful treatment is considered a pioneering medical act that saved the baby's life.
