Thoracic vascular congenital anomalies are malformations with significant clinical implications. One of the rarest anomalies is the anomalous origin of the brachiocephalic trunk from the pulmonary trunk, often associated with serious complications such as pulmonary hypertension. Diagnosis is facilitated by advanced imaging techniques, including MRI and CT scans. We present a case of a premature newborn with congenital heart disease (hypoplastic right ventricle) who developed respiratory and septic complications. A CT angiography revealed a left innominate artery arising from the pulmonary trunk. Despite valvuloplasty and multidisciplinary management, the infant passed away at two and a half months due to multi-organ failure. Early diagnosis and interdisciplinary management, aided by advanced imaging techniques such as CT angiography, are crucial for improving outcomes in patients with complex congenital heart malformations.
胸段血管先天性异常是具有重大临床意义的畸形。最罕见的异常之一是头臂干从肺动脉异常起源，常伴有诸如肺动脉高压等严重并发症。先进的成像技术，包括磁共振成像（MRI）和计算机断层扫描（CT）扫描，有助于诊断。我们报告一例患有先天性心脏病（右心室发育不全）的早产新生儿，该患儿出现了呼吸和败血症并发症。CT血管造影显示左无名动脉起源于肺动脉干。尽管进行了瓣膜成形术和多学科管理，但该婴儿由于多器官衰竭在两个半月时死亡。借助CT血管造影等先进成像技术进行早期诊断和跨学科管理，对于改善复杂先天性心脏畸形患者的治疗结果至关重要。
