NCS can be classified into anterior and posterior types regarding the origin of LRV compression: anterior NCS occurs when LRV is compressed between the aorta and superior mesenteric artery, whereas posterior NCS involves LRV compression between the aorta and the spine. Despite advancements in diagnostic modalities, including Doppler ultrasound, computed tomography, magnetic resonance imaging, and invasive techniques like phlebography, there is still no globally accepted diagnostic algorithm, leading to inconsistencies in diagnosis. Moreover, due to the lack of standardized treatment guidelines, the optimal management of anterior NCS remains a topic of debate. While conservative management is usually recommended in the pediatric population, invasive treatments-including surgical options like LRV transposition and renal autotransplantation, as well as interventional radiology procedures like stenting, present challenges such as stent migration, restenosis, and long-term material durability. Nevertheless, the emergence of 3D-printed stents offers potential improvements in patient-specific treatment, particularly in the pediatric population, yet their clinical efficacy and safety remain under investigation.
