Hemoptysis is when cough up blood from lungs. It can be a sign of a serious medical condition. Infections, cancer, and problems in blood vessels in your lungs can cause it. As an alternative to surgery, bronchial artery embolization (BAE) has established itself as the first-line treatment of life-threatening hemoptysis. It is a minimally invasive endovascular procedure with lower morbidity and mortality as compared with surgery.
