An urgent, minimally invasive procedure that stops life-threatening coughing up of blood by sealing the abnormal bronchial arteries responsible — without open chest surgery.
Hemoptysis is the medical term for coughing up blood from the lungs or airways. It ranges from small streaks of blood mixed with sputum to massive, life-threatening bleeding that can rapidly fill the airway and cause suffocation — which is why the immediate danger in severe hemoptysis is asphyxiation from blood flooding the airway, not blood loss itself, even though the volume of blood lost matters too. Any significant or recurrent hemoptysis needs prompt medical evaluation to identify the source and cause.
The lungs have two separate blood supplies: the pulmonary arteries, which carry low-pressure blood for gas exchange, and the bronchial arteries, a smaller, high-pressure system that nourishes the airways themselves. In most significant hemoptysis, the bleeding actually comes from the bronchial arteries, or from abnormal, enlarged bronchial and related systemic vessels that develop in response to chronic lung disease — which is why treatment is targeted specifically at this bronchial (and related systemic) circulation rather than the pulmonary arteries.
Past or present, including old TB scarring and cavities — one of the most common causes in this region.
Chronically damaged, dilated airways, often following earlier infections.
Lung abscess, or aspergilloma — a fungus ball forming within an old cavity.
Tumours invading or eroding into a blood vessel.
A needle puncture is made in the groin under local anaesthesia, with or without light sedation.
A catheter is guided selectively into the bronchial arteries feeding the bleeding area.
Particles or coils block the abnormal vessels while preserving normal lung blood flow.
Most patients are monitored in hospital for a period depending on their presentation.
A wide range of lung conditions can lead to hemoptysis significant enough to need embolization, most of them causing chronic inflammation or scarring that triggers abnormal, fragile, high-pressure blood vessels to grow into the affected lung tissue:
Tuberculosis, past or present, including old TB scarring and cavities — one of the most common causes in this region.
Bronchiectasis — chronically damaged, dilated airways, often following earlier infections.
Chronic infections, lung abscess, or fungal disease (such as aspergilloma, a fungus ball forming within an old cavity).
Lung cancer or other tumours invading or eroding into a blood vessel.
Less commonly, pulmonary artery pseudoaneurysm, vascular malformations, or a complication of a prior procedure.
Identifying the underlying cause matters not just for planning the embolization itself, but for the patient's long-term management afterward, since treating the acute bleed doesn't treat the disease that caused it.
In an actively bleeding patient, initial priorities are protecting the airway and stabilising breathing and circulation. A CT angiogram of the chest is typically the key investigation — it identifies the likely bleeding source, shows the underlying lung disease, and maps the abnormal, enlarged bronchial arteries and any other vessels contributing to the bleeding, which helps plan the embolization in detail before the patient even reaches the angiography suite. Bronchoscopy may also be used, particularly to help localise the bleeding side or segment when imaging is inconclusive, or to allow direct airway measures if bleeding is immediately life-threatening.
Access: under local anaesthesia, with or without light sedation, a needle puncture is made in the femoral artery in the groin.
Angiography: a catheter is guided into the aorta and then selectively into the bronchial arteries — and any other abnormal systemic vessels feeding the bleeding area identified on the pre-procedure CT — with contrast dye used to confirm the abnormal, hypertrophied vessel pattern responsible for the bleeding.
Superselective catheterisation: a fine microcatheter is advanced as precisely as possible into the specific abnormal vessel, an approach called superselective embolization, which improves both the effectiveness of the treatment and its safety by avoiding non-target vessels.
Embolization: particles, coils, or a combination of embolic materials are injected to block the abnormal vessels and stop the bleeding, while preserving normal blood flow to the surrounding lung tissue.
Closure and recovery: the puncture site is closed with pressure or a closure device, and the patient is monitored closely, typically in hospital for a period afterward that depends on how unwell they were at presentation.
The procedure typically takes one to two hours, and the vast majority of patients experience immediate control of bleeding, often within the procedure itself.
Bronchial artery embolization sits very close to structures where a mistake genuinely matters. In a small proportion of people, an artery supplying part of the spinal cord arises from, or very close to, a bronchial artery — a variant that must be specifically identified and avoided during the procedure, since inadvertently embolizing it can cause spinal cord injury, a rare but serious recognised complication of this procedure. This is precisely why bronchial artery embolization is a technically demanding procedure that depends on an experienced interventional radiologist carefully mapping each vessel's anatomy on angiography before any embolic material is injected, rather than treating it as a routine or generic embolization.
Most patients are observed in hospital for a period after the procedure, with attention to the underlying lung condition that caused the bleeding in the first place — treating that underlying disease, whether it's active infection, ongoing tuberculosis treatment, or another cause, is just as important as the embolization itself in preventing further episodes. Bleeding recurs in a meaningful minority of patients, generally over the following months to a year, most often because the underlying lung disease progresses or new abnormal vessels develop, rather than because the original embolization failed. Recurrent bleeding is usually managed successfully with a repeat embolization procedure, which is why closely coordinated, ongoing follow-up with the treating chest physician or pulmonologist matters well beyond the immediate procedure.
Successful management of hemoptysis depends on rapid coordination between emergency care, pulmonology, and interventional radiology — getting the patient stabilised, imaged, and to embolization quickly when bleeding is significant, while the interventional team applies the meticulous, superselective technique this procedure demands. Because the underlying cause so often needs its own ongoing treatment, the relationship between the interventional radiology team and the patient's pulmonologist or physician typically continues well past the day of the procedure itself.
It's typically performed urgently, once significant hemoptysis is confirmed and the bleeding source identified on imaging, and is considered the first-line treatment for hemoptysis that can't be controlled conservatively — for an actively bleeding patient, the first step is always emergency medical care to stabilise breathing and circulation.
No — it's done entirely through a needle puncture in the groin, under local anaesthesia, without any chest incision or removal of lung tissue.
Immediate bleeding control is achieved in the large majority of cases — commonly cited figures range from around 70% to over 90%, depending on the underlying cause and the completeness of embolization — making it considerably safer than emergency lung surgery for most patients.
Bleeding recurs in a minority of patients, usually related to progression of the underlying lung disease rather than the embolization itself, and is generally managed successfully with a repeat procedure alongside continued treatment of the underlying condition.
Common causes include tuberculosis and its long-term lung scarring, bronchiectasis, chronic infections, fungal disease, and lung tumours — all of which can trigger abnormal, fragile, high-pressure blood vessels to develop in the affected lung tissue.
