Abstract

Anomalous systemic arterial supply to normal lung (ASANL) is a rare vascular anomaly, typically characterized by the presence of an accessory systemic arterial blood supply to a lobe or segment of the lung, in which the bronchial structures and pulmonary arterial-venous systems are completely normal. This condition is frequently incidentally discovered due to it typically progresses silently without symptoms or with non-specific clinical manifestations. Early and accurate diagnosis is essential to prevent complications, particularly life-threatening hemoptysis. We report two cases examined and managed at the National Lung Hospital, both of which presented with atypical or absent respiratory symptoms. Preoperative diagnoses in both patients suggested pulmonary sequestration; however, postoperative histological findings revealed features more consistent with anomalous systemic arterial supply to normal lung. Through these cases, we aim to share our experience and promote early recognition and accurate diagnosis of this condition, thereby supporting optimal management and prevention of severe complications.
