Describe the pathophysiology of hemoptysis and the relevant anatomyof bronchial and non-bronchial systemic arteries Evaluate the indicationsof bronchial artery embolization (BAE) as well the the diagnostic work-up prior to the procedure. Describe the imaging findings,
outcomesand complications of bronchial artery embolization (BAE).
The expectoration of blood from the respiratory tract is defined as hemoptysis.
The classification of the severity of hemoptysis in literature demonstrates an element of subjectivity as there are many factors which can contribute to the impact of the symptome.g.
volume of bleeding,
duration of presentation and the impact on clinical state of the patient. With the aforementioned factors in mind,
it canbeen classified into different grades of severity; mild,
moderate and severe/massive: Mild...
Findings and procedure details
Diagnostic Evaluation: Pre-procedure Prior to the treatment of hemoptysis by BAE,
a full clinical history and examination should be performed to formulate a list of differential diagnoses and potential causes for the bleeding.
As discussed previously,
hemodynamically instability warrants urgent resuscitation of the patient and close monitoring of vital signs prior to any intervention. Chest radiography is recommended by the American College of Radiology (ACR) for all new cases of hemoptysis...
Hypertrophy of bronchial vessels due to lung parenchymal abnormalities is the main cause of acute,
life-threatening hemoptysis. Bronchial artery embolization (BAE) is a well-known,
established treatment and has an excellent technical success rates due to improvements in embolization agents,
materials and techniques. Recurrence of bleeding is dependent on primary lung disease etiology,
recanalization of primary embolization and development of collateral circulations which can be managed...
