Summary
Pulmonary arteriovenous malformation (PAVM) can occur independently or with hereditary hemorrhagic telangiectasia. Surgical lobectomy offers a safe and effective treatment for large, centrally located PAVMs, especially in high-risk individuals.
Area of Science:
- Cardiology
- Thoracic Surgery
- Radiology
Background:
- Pulmonary arteriovenous malformations (PAVMs) are abnormal connections between pulmonary arteries and veins.
- PAVMs can be congenital or associated with hereditary hemorrhagic telangiectasia (HHT).
- Diagnosis and treatment of PAVMs have evolved with advancements in imaging and interventional radiology.
Observation:
- A case of a large, solitary PAVM in the central lower lobe of the left lung is presented.
- The patient was a 75-year-old woman with this uncommon lesion.
- Contrast echocardiography was utilized for lesion evaluation.
Findings:
- The PAVM was successfully treated with a lobectomy.
- Surgery was considered the first-line option due to the lesion's size, central location, and patient's high-risk status.
- Obliterative techniques are alternatives but may not be suitable for all PAVM presentations.
Implications:
- Lobectomy remains a safe and effective surgical option for specific PAVM cases.
- Accurate diagnostic tools like contrast echocardiography are crucial for PAVM management.
- Treatment decisions for PAVMs should be individualized based on lesion characteristics and patient factors.
