Endovascular coil embolization for anomalous systemic artery supply to the lower lateral segment of the left lung: a case report

Year: 2026

Type: article

Abstract: A 40-year-old female who presented with "hemoptysis for 3 days" was referred to our hospital due to suspected bronchial artery malformation. Physical examination revealed no obvious abnormalities. Aortic CT angiography with three-dimensional reconstruction showed the descending aorta had an abnormal branch supplying the lower lateral segment of the left lung. Left pulmonary artery angiography under DSA showed poor filling of the lower lateral segment artery of the left lung, and aortography revealed an abnormal branch originating from the lower segment of the thoracic aorta supplying the left lower lateral segment. The diagnosis of anomalous systemic artery supply to the lower lateral segment of the left lung was confirmed. After angiography, a microcatheter was used to select the abnormal vessel, and coils were placed to embolize the abnormal artery. Re-angiography after embolization showed that the distal vessel disappeared. The patient had no obvious discomfort or complications during or after the procedure. Two months later, contrast-enhanced CT scan showed that the shadow of the left lower lobe had significantly absorbed, the coils were in place as expected, and the abnormal blood vessel was blocked well.
