A large pulmonary arteriovenous malformation (PAVM) was identified in a woman presenting with exertional breathlessness and anemia. Surgical resection via lobectomy led to a full recovery, highlighting PAVM management.
Area of Science:
- Cardiology
- Pulmonology
- Vascular Surgery
Background:
- Pulmonary arteriovenous malformations (PAVMs) are abnormal connections between pulmonary arteries and veins.
- PAVMs can lead to significant complications, including hemorrhage and paradoxical embolism.
- Diagnosis and management of PAVMs are crucial for patient outcomes.
Observation:
- A 49-year-old woman presented with dyspnea on exertion and iron deficiency anemia.
- Imaging revealed a large right lung mass, diagnosed as a pulmonary arteriovenous malformation with an aneurysmal sac.
Findings:
- Surgical lobectomy was performed for the PAVM.
- The patient experienced an uncomplicated recovery following the procedure.
Implications:
- This case underscores the importance of considering PAVMs in patients with unexplained respiratory symptoms and anemia.
- Surgical intervention, such as lobectomy, can be effective for treating symptomatic PAVMs.
- Understanding PAVM pathophysiology and diverse clinical presentations is vital for accurate diagnosis and timely treatment.
