Coil Embolization via Endovascular Approach for Abnormal Systemic Arterial Supply to the Left Lung's Lower Lateral Segment: A Case Study

1

A 40-year-old female presented with hemoptysis and was diagnosed with an anomalous systemic artery supplying the left lung's lower lateral segment.
2

CT angiography revealed an abnormal branch from the descending aorta supplying the affected lung segment, confirming the vascular malformation.
3

Endovascular coil embolization was successfully performed to occlude the abnormal artery, with no complications reported during or after the procedure.
4

Post-embolization imaging showed the distal vessel was no longer visible, and the exudative lesion in the left lower lobe significantly absorbed.
5

This case highlights the importance of recognizing rare congenital vascular malformations to prevent misdiagnosis and improve patient outcomes.
