Case report: Total obstruction of the left main bronchus by a blood clot leads to pneumonectomy in a pregnant woman.

INTRODUCTION AND

IMPORTANCE

Airway obstruction resulting from blood clot formation is observed across various clinical scenarios and is often preceded by hemoptysis. This condition can significantly compromise respiratory function, potentially leading to life-threatening ventilatory distress.

CASE PRESENTATION: In this report, the authors present a case of acute airway obstruction associated with hemoptysis in an 18-week pregnant woman admitted to the emergency department for acute respiratory distress. Clinical and radiographic evidence strongly suggested the presence of an endobronchial blood clot causing focal airway obstruction. Diagnosis was confirmed through direct endoscopic evaluation.

CLINICAL DISCUSSION: Initial attempts to remove the obstructing clot from the airway involved lavage, aspiration, and forceps extraction by using a bronchoscope. In cases in which these measures proved ineffective, other management strategies include rigid bronchoscopy, embolization, and surgical resection.

CONCLUSION

Central airway obstruction is a critical condition caused by numerous factors such as tumours or blood clots. Treatment focuses on securing the airway, ensuring breathing, and using tools such as bronchoscopy for diagnosis and treatment. Surgery is considered a last resort when other methods are ineffective.
