Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, your son is having pulmonary embolism. It is blood clot in pulmonary artery. Since his age is only 3 weeks, possibility of congenital coagulation defect is more. Coagulation system is there in the body. There are two kinds of chemicals, coagulants and anti coagulants in the body. Coagulants will form blood clots while anti coagulants will prevent clot formation. So in your children case there must be higher coagulants and absent anti coagulants. Such diseases are as follows. 1. Protein C deficiency 2. Protein S deficiency 3. Homocysteinuria4. Hypervitaminosis K etc. So better to consult hematologist and get done blood levels of these chemicals. Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks.
