{"cited_by_count":273142,"description":"This cluster of papers focuses on a wide range of venous anomalies and syndromes in the vascular system, including anomalies of the inferior vena cava, superior mesenteric artery syndrome, nutcracker syndrome, vascular compression syndromes, and venous aneurysms. The papers discuss the diagnosis, imaging findings, clinical implications, treatment strategies, and surgical interventions for these venous abnormalities.","display_name":"Vascular anomalies and
