Summary
Pulmonary arteriovenous fistulas (PAFs) are rare lung malformations. This case highlights PAFs presenting as hemoptysis, successfully treated with lobectomy.
Area of Science:
- Cardiology
- Pulmonology
- Radiology
Background:
- Pulmonary arteriovenous fistulas (PAFs) are uncommon vascular malformations.
- PAFs are often congenital, associated with Osler-Weber-Rendu disease, but can be acquired.
- The Institute of Tuberculosis and Chest Diseases has observed 11 congenital PAF cases among 4000 resected lungs.
Observation:
- A 40-year-old male presented with hemoptysis, initially suspected as tuberculosis or cancer.
- Chest X-rays showed a right upper lobe infiltrate that progressed despite antitubercular treatment.
- Persistent, life-threatening hemoptysis prompted surgical intervention without prior angiography.
Findings:
- Right upper lobectomy revealed pulmonary arteriovenous fistulas in the resected lobe.
- The patient experienced complete symptom resolution post-surgery.
- Post-operative angiography was declined by the patient.
Implications:
- This case underscores the importance of considering PAFs in patients with unexplained hemoptysis and progressive lung infiltrates.
- Surgical resection can be an effective treatment for symptomatic PAFs, even in the absence of pre-operative diagnosis via angiography.
- Early recognition and management of PAFs are crucial for preventing potentially fatal hemorrhages.
