Learning objectives Review the anatomy, embryogenesis, and pathophysiology of congenital pulmonary artery and vein anomalies. Correlate clinical findings and patient complaints with imaging results of pulmonary vascular anomalies. Summarize imaging protocols, including post-processing techniques for pulmonary vascular evaluation. Highlight the role of non-invasive and invasive imaging in diagnosing pulmonary artery and vein anomalies. Discuss the role of radiologists in multidisciplinary teams for diagnosis, treatment planning, and patient follow-up.
Read more Background Congenital anomalies of the pulmonary vasculature include a variety of malformations that arise due to errors in embryological development. These anomalies may remain asymptomatic or present with nonspecific symptoms such as respiratory distress, frequent infections, hemoptysis, or pulmonary hypertension, making diagnosis challenging. Early detection is crucial for effective management, as these conditions can lead to serious complications, including heart failure, inadequate blood oxygenation, and pulmonary hypertension.The prevalence of pulmonary vascular malformations varies depending on the specific type and the population...
Read more Findings and procedure details Pulmonary Vein Anomalies Embryology of Pulmonary Veins:The primordial lung buds are surrounded by the vascular plexus of the foregut (splanchnic plexus), which initially lacks direct connections to the heart. During development, the common pulmonary vein (CPV) establishes a connection between the pulmonary venous plexus and the sinoatrial portion of the heart. Over time, connections between the pulmonary venous plexus and the splanchnic plexus regress, and the CPV incorporates into the left atrium (LA). This process allows individual pulmonary veins to connect...
Read more Conclusion Congenital anomalies of the pulmonary arteries and veins represent a diverse group of conditions, often diagnosed incidentally or due to clinical symptoms. Early recognition through detailed imaging studies, particularly CTA, is crucial for accurate diagnosis and management. Radiologists play a central role in identifying these anomalies, aiding in surgical or interventional planning, and contributing to improved patient outcomes. [fig 24] Multidisciplinary collaboration ensures the best care for patients with these complex conditions.
