A rare, large pulmonary arteriovenous malformation (PAVM) with aneurysm was successfully treated with surgery. This case highlights a surgical approach for complex PAVMs presenting with serious complications like brain abscess.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Malformations
Background:
- Pulmonary arteriovenous malformations (PAVMs) are abnormal connections between pulmonary arteries and veins.
- Large, centrally located PAVMs with aneurysmal changes are infrequent and pose treatment challenges.
- Optimal management strategies for complex PAVMs remain under investigation.
Observation:
- A 63-year-old female presented with dyspnea and a brain abscess, indicative of a serious complication.
- Diagnostic imaging revealed a large, centrally located PAVM with aneurysmal formation in the pulmonary hilum.
- The patient's symptoms were attributed to the complex vascular malformation.
Findings:
- A muscle-sparing thoracotomy was performed for surgical resection of the PAVM.
- The procedure involved a left upper lobe lobectomy.
- Three-dimensional reconstruction imaging guided the surgical approach, ensuring precision.
Implications:
- This case demonstrates the successful surgical management of a complex, centrally located PAVM.
- The use of 3D imaging facilitated a precise and effective surgical intervention.
- This approach may offer a viable treatment option for similar challenging PAVM cases.
