Utility of indocyanine green in assessing blood perfusion in anomalous systemic arterial supply to the lung.

The chosen treatment for anomalous systemic arterial supply to the basal segment of the lung (ABLL) is typically the division of the anomalous artery and resection of the abnormal area, dependent on the anomalous artery. Although only division or interventional embolization of the anomalous artery may be selected. However, leaving the area dependent on the anomalous artery can lead to complications, such as necrosis and pulmonary infarction. We report the case of a 39-year-old female with ABLL. Intraoperatively, the anomalous artery was first divided. Indocyanine green (ICG) was subsequently injected intravenously to evaluate blood perfusion within the abnormal lung area. Since the abnormal area was still poorly perfused after a few minutes, a left basal segmentectomy was performed because of the possibility of complications. Thus, evaluation of perfusion via ICG can be used in the decision to resect abnormal area.
