Move the mouse cursor over the PINK text boxes inside the flow chart to bring up a pop up box with salient points.
Clicking on the PINK text box will bring up the full text.
The relative radiation level (RRL) of each imaging investigation is displayed in the pop up box.
| SYMBOL | RRL | EFFECTIVE DOSE RANGE |
 | None | 0 |
 | Minimal | < 1 millisieverts |
 | Low | 1-5 mSv |
 | Medium | 5-10 mSv |
 | High | >10 mSv |

Post-Primary Pulmonary Tuberculosis Image 1 (Plain Radiograph): Pulmonary tuberculosis is an important cause of haemoptysis. This chest radiograph demonstrates patchy bilateral opacification of the upper lung lobes with cavitation most marked on the left (arrow) consistent with post-primary tuberculosis. |
| 2 |  |
Pulmonary Haemorrhage Image 2 (Plain Radiograph): There is widespread airspace opacification of both lungs with air brochograms. This patient had bilateral pulmonary haemorrhage due to Goodpasture's (Anti-GBM) syndrome. |
| 3a |  |
Pulmonary Haemorrhage Image 3a (Plain Radiograph) and 3b (Bronchial Angiogram): Image 3a demonstrates right apical consolidation with cavitation due to mycetoma formation on a background of tuberculosis (arrow). The bronchial artery was embolised with gel foam and coils due to recurrent haemoptysis (Image 3b). |

Teaching Points
Teaching Points
- A chest radiograph may reveal a cause of haemoptysis
- If there is a clinical suspicion of an underlying abnormality, CT of the chest is indicated
- Further investigations are dictated by CT findings. This may include a bronchoscopy if a neoplastic lesion is seen or an angiogram if a vascular abnormality is suspected
- Massive haemoptysis (>300mL in 24hrs) is a medical emergency. Depending on whether the patient is haemodynamically stable, diagnostic tests (e.g. CT scan) may be undertaken. However, if the patient is compromised bronchoscopy is preferred initially, as it affords therapeutic intervention at the same time
angio
Bronchial Angiography
- Indicated when bronchial embolisation is intended 9
- Angiographic signs of pulmonary haemorrhage include extravasation of contrast media, hypervascularisation, abnormal arborisation of bronchial arteries, systemic-pulmonary shunts and bronchial artery aneurysms
bronch
Flexible Or Rigid Bronchoscopy
- Urgent bronchoscopy is indicated in unstable patients with massive haemoptysis
- Rigid bronchoscopy offers greater suctioning ability and maintenance of airway patency but flexible bronchoscopy may be more appropriate for peripheral lesions 9,10
- Precedes bronchial angiography and embolisation to locate the bleeding site (sensitivity 67%) 1
ct
Computed Tomography (CT)
- Most sensitive diagnostic test with a positive yield of 67% 1,5,6
- Primary investigation in patients with normal or non-localising chest radiographs 6,9
- Initial Chest CT before bronchoscopy in patients in whom the chest radiograph is abnormal or suggestive of malignancy is cost effective in improving diagnostic yield from invasive diagnostic procedures and in some cases, eliminates the need for any further investigation 3,6,7
- In patients with non-massive haemoptysis, intravenous contrast is given if there are abnormalities seen on the chest radiography
- Useful for
- Bronchiectasis is the second most common cause of haemoptysis diagnosed on CT. Multidetector CT with thin collimation or conventional High Resolution CT is required to identify and define the type and extent of this disease 3
- More information on high resolution computed tomography (HRCT)
- Limitations of CT - insensitive to early mucosal abnormalities 3,5
embo
Bronchial Artery Embolisation
- Effective treatment adjunct to control bronchial bleeding and reduces the need for high-risk emergency lung resections (immediate control of bleeding in 75-93% of cases) 10,11,12
- Aims to reduce the systemic arterial perfusion pressures to the fragile vessels within inflammatory tissue and to try to prevent the development and enlargement of non-bronchial systemic arterial collaterals 9
- Reserved for patients with life threatening haemoptysis
- Helps avoid surgery in patients who are not good surgical candidates 11
- Limitations 11,12
- 20% recurrence rate
- Potential complications include accidental embolisation of the spinal artery either by contrast material or the embolising particles causing ischaemic injury to the spinal cord
- 0-20% technical failure rate due to inability to cannulate the vessel, instability of the catheter tip, or visualisation of anterior spinal artery
hrct
High Resolution Computed Tomography (HRCT)
- Investigation of choice for suspected bronchiectasis which is the second most common cause of haemoptysis. 3
- Thick slice helical CT is not effective as a screening modality for bronchiectasis.
xray
Chest Radiograph (CXR)
- May detect a cause of haemoptysis in 40-50% of cases 1,10
- Patients with negative chest radiograph and two or more risk factors for malignancy (>50yrs old, >40 pack year smoking history) need to be further investigated 2
- Patients with fewer than two risk factors for malignancy can be followed by observation 2
