Coughing Up Blood (Hemoptysis):
How Bronchial Artery Embolization (BAE) Can Help
Seeing blood while coughing can be frightening. While a small streak of blood may sometimes occur with a severe cough or chest infection, recurrent or significant amounts of blood should never be ignored.
Coughing up blood, medically known as hemoptysis, may be a sign of an underlying lung condition or abnormal blood vessel that requires medical evaluation. In severe cases, the bleeding can become life-threatening and may require urgent treatment.
Today, advances in Interventional Radiology allow many cases of significant or recurrent hemoptysis to be treated without major surgery using a minimally invasive procedure called Bronchial Artery Embolization (BAE).
Bronchial Artery Embolization is a minimally invasive, image-guided procedure used to control bleeding from abnormal bronchial arteries.
Why Does the Bleeding Occur?
The lungs receive blood through two different circulatory systems—the pulmonary circulation and the bronchial circulation.
In many cases of significant hemoptysis, the bleeding originates from the bronchial arteries. Chronic infection or inflammation can cause these arteries to become enlarged, abnormal and fragile.
These abnormal vessels may eventually rupture, allowing blood to enter the airways and resulting in hemoptysis.
What Is Hemoptysis?
Hemoptysis refers to blood that is coughed up from the respiratory tract. The amount can range from small streaks mixed with sputum to significant bleeding.
The severity of hemoptysis depends not only on the amount of blood but also on factors such as the patient’s underlying condition, breathing and overall clinical stability.
While minor bleeding may occur with respiratory infections or irritation, recurrent or substantial hemoptysis needs prompt medical assessment to identify its source and underlying cause.
What Causes Hemoptysis?
There are several possible causes of coughing up blood, including:
· Tuberculosis (TB)
· Bronchiectasis
· Lung infections
· Lung cancer
· Fungal infections
· Chronic inflammatory lung diseases
· Blood vessel abnormalities
· Trauma
Identifying the underlying condition is important because controlling the bleeding and treating its cause are both essential parts of patient management.
Enlarged and fragile bronchial arteries can rupture and become a source of significant bleeding into the airways.
The Role of Interventional Radiology
When hemoptysis is significant or recurrent, simply identifying the source of bleeding may not be enough—the bleeding vessel may need to be treated.
This is where Interventional Radiology plays an important role.
Instead of performing open surgery, an Interventional Radiologist can navigate through the body’s blood vessels using small catheters and real-time imaging to reach the abnormal artery responsible for bleeding.
One of the key treatments used for this purpose is Bronchial Artery Embolization.
How Is Hemoptysis Diagnosed?
The first priority is to determine why the bleeding is occurring and where it is coming from.
· Clinical examination
· Chest X-ray
· CT scan / CT bronchial angiography
· Bronchoscopy in selected patients
CT angiography can be particularly useful in demonstrating abnormal blood vessels and helping plan further treatment.
What Is Bronchial Artery Embolization?
Bronchial Artery Embolization (BAE) is a minimally invasive, image-guided procedure used to selectively block abnormal bronchial arteries responsible for bleeding.
The Interventional Radiologist identifies the abnormal blood vessel using angiography and then delivers embolic material through a small catheter to reduce or stop blood flow to the bleeding vessel.
The objective is highly targeted: control the source of bleeding while preserving circulation to healthy tissue.
How Is Bronchial Artery Embolization Performed?
BAE is performed through a small vascular access point and does not require a large surgical incision.
Step 1 – Vascular Access
A small catheter is introduced through a tiny puncture, usually through an artery in the wrist or groin.
Step 2 – Image-Guided Navigation
Using real-time X-ray guidance, the catheter is carefully navigated through the blood vessels towards the abnormal bronchial artery.
Step 3 – Embolization
Once the bleeding vessel has been identified, specialised embolic material is delivered through the catheter to selectively block the abnormal vessel.
Step 4 – Controlling the Bleeding
By reducing or stopping blood flow through the abnormal artery, the source of bleeding can be controlled while healthy lung tissue continues to receive blood through other normal vessels.
Angiography allows the Interventional Radiologist to identify the abnormal bronchial artery responsible for bleeding.
Embolic material is delivered through a microcatheter to selectively block the abnormal vessels responsible for bleeding.
Advantages of Bronchial Artery Embolization
· Minimally invasive
· No large surgical incision
· Effective in controlling significant bleeding
· Can be life-saving in emergency situations
· Shorter recovery compared with major surgery
· May help avoid emergency lung surgery
Because the treatment is performed from within the blood vessels, it can provide a targeted approach even in patients who may be seriously unwell.
Who May Benefit from BAE?
· Tuberculosis-related bleeding
· Bronchiectasis
· Chronic lung infections
· Lung tumours
· Recurrent hemoptysis
· Massive or life-threatening hemoptysis requiring urgent treatment
The decision to perform embolization depends on the cause and severity of bleeding, imaging findings and the patient’s overall clinical condition.
Case Study: Emergency Embolization for Massive Hemoptysis
28-year-old man | Previous pulmonary tuberculosis (Koch’s disease) | ~400 mL hemoptysis
A 28-year-old man with a previous history of pulmonary tuberculosis (Koch’s disease) presented with an acute episode of approximately 400 mL of hemoptysis.
The patient required assessment and stabilization, and imaging demonstrated prominent abnormal bronchial arteries as the likely source of bleeding.
Endovascular embolization was subsequently performed to target and control the abnormal vessels.
1. Clinical Presentation
Chest radiograph of the patient presenting with a significant episode of hemoptysis.
2. Identifying the Source of Bleeding
Angiographic evaluation demonstrating prominent abnormal bronchial arterial circulation.
3. Targeted Bronchial Artery Embolization
BEFORE EMBOLIZATION
AFTER EMBOLIZATION
Angiographic comparison before and after selective bronchial artery embolization.
Clinical Takeaway
This case demonstrates the role of image-guided embolization in identifying and selectively treating abnormal bronchial arteries in a patient presenting with significant hemoptysis.
Frequently Asked Questions
Is Bronchial Artery Embolization painful?
Most patients experience very little discomfort. The procedure is generally performed using local anaesthesia, and medication may also be given to help the patient remain comfortable during treatment.
Is BAE an emergency procedure?
It can be. In patients with severe or life-threatening hemoptysis, Bronchial Artery Embolization may be performed urgently to control active bleeding.
Can the bleeding return after embolization?
Many patients achieve effective control of bleeding following embolization. However, hemoptysis can recur, particularly if the underlying lung disease persists or progresses. In some patients, repeat embolization may be required.
Will I still need surgery?
In many cases, embolization can successfully control bleeding and help avoid emergency surgery. Whether surgery or other treatment is required later depends on the underlying disease and the patient’s individual clinical situation.
When Should You Seek Medical Attention?
Coughing up blood should not simply be ignored.
Medical evaluation is particularly important when the bleeding is recurrent, increasing or more than a small streak, or when it occurs in someone with a known lung condition.
Significant coughing of blood accompanied by difficulty breathing, chest pain, dizziness, weakness or substantial blood loss requires urgent medical attention.
Early evaluation helps identify both the underlying cause and the most appropriate treatment.
Controlling Bleeding Without Major Surgery
Bronchial Artery Embolization has become an important minimally invasive treatment for patients with significant or recurrent hemoptysis.
By using advanced imaging and catheter-based techniques, an Interventional Radiologist can identify and selectively treat abnormal bleeding vessels without the need for major surgery in many cases.
The goal is straightforward: control the bleeding, treat the problem as precisely as possible and help the patient recover safely.
Experiencing Recurrent Hemoptysis?
If you have experienced recurrent coughing of blood or have been advised to undergo embolization, consultation with an Interventional Radiologist can help determine whether Bronchial Artery Embolization may be appropriate for your condition.
