Surgical repair effectively treats giant pulmonary artery aneurysms, preventing life-threatening rupture. Postoperative imaging surveillance is crucial for long-term success and monitoring graft health.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Pulmonary artery aneurysm (PAA) is a rare condition defined by pulmonary artery trunk dilation >4 cm.
- Giant or symptomatic PAAs pose risks of dissection, thrombosis, or rupture, necessitating surgical intervention.
- Standardized postoperative follow-up protocols for PAA are lacking.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
