Abnormal systemic artery to the left lower lobe is a rare congenital abnormality characterized by anomalous communication between the systemic and pulmonary circulation. Owing to its rarity, there is limited clinical experience with respect to the diagnosis and treatment of this disease.
We report a 60-year-old man who presented with a history of hemoptysis for 20 d. Contrast-enhanced computed tomography of the chest confirmed the diagnosis of abnormal systemic artery to the left lower lobe, and surgical treatment was performed. The aberrant artery arising from the descending thoracic aorta was ligated, followed by removal of the left lower lobe. The patient showed good recovery and was discharged 6 d after the surgery. At the 1-year follow-up, the patient had recovered completely, and lung CT showed no abnormal findings.
We present a case of abnormal systemic artery to the left lower lobe that was successfully managed by surgical resection of the aberrant artery and the left lower lobe. This case report adds to the clinical experience of diagnosing and treating this rare entity.
Core Tip: Abnormal systemic artery to the left lower lobe is a rare congenital vascular malformation. Experience in diagnosis and treatment remains limited. Here we pre
