Embolization is a procedure where a doctor uses a thin tube (catheter) to reach the bleeding blood vessel and blocks it using special materials like coils, glue, gel foam, or tiny particles.
This treatment:
- Stops active internal bleeding quickly
- Targets only the bleeding vessel
- Avoids major surgery in many cases
- Helps stabilize the patient and save lives
Trauma is one of the most common reasons for sudden internal bleeding — from road accidents, falls, or abdominal injuries. But not all internal bleeding comes from trauma alone. Bleeding can also originate from the digestive tract, which is why gastrointestinal bleeding is treated using the same embolization approach — blocking the exact vessel that is leaking, without opening the abdomen.
When bleeding occurs in the chest and a patient is coughing up blood, the source is often an abnormal or damaged airway vessel. In such cases, bronchial artery embolization is performed to seal off that vessel precisely — stopping the bleeding without the need for lung surgery.
In some patients, bleeding is not caused by an injury at all but by a weakened blood vessel wall that has expanded and burst. These are called aneurysms. A visceral aneurysm — occurring in arteries supplying the liver, spleen, or kidneys — can rupture suddenly and cause life-threatening internal bleeding, making early diagnosis and embolization critical.
