Abstract
An aberrant right subclavian artery (ARSA) and persistent left superior vena cava (PLSVC) are rare congenital anomalies of the cardiovascular system. This case presents the rare copresence of an ARSA and PLSVC, identified in a 22 week old fetus. The ARSA, an atypical anatomical variant where the right subclavian artery arises abnormally from the aortic arch, was observed along with the PLSVC, also an anatomical variation where the left superior vena cava persists and drains into the right atrium through coronary sinus that becomes dilated consequently. Ultrasound imaging provided detailed visualization of both anomalies and their concurrent existence leading to this rare prenatal diagnosis. This copresence is clinically significant due to its potential implications for fetal cardiovascular development and associated genetic conditions.
