Anomalous systemic arterial supply to the basal segments of the lung with three aberrant arteries

Abstract

We report a case of anomalous systemic arterial supply with three aberrant arteries supplying the basal segments of the right lung. There is no published report of a patient of anomalous systemic arterial supply to the basal segments with three aberrant arteries. Transverse computed tomography (CT) showed one aberrant artery in the right lower lobe, and preoperative three-dimensional CT showed three aberrant arteries, which provided detailed information and assisted in the thoracoscopic surgery. The patient underwent a complete thoracoscopic right lower lobectomy.

Anomalous Systemic Vessel to the Lung with Hypoplastic Left Heart Syndrome in a Fetus

“…Anomalous systemic arterial supply to normal basal segments of the left lower lobe is an uncommon condition. The anomalous vessel, distinct from bronchial arteries [7,12], usually arises from the thoracic aorta, abdominal aorta, or celiac axis and supplies the basal segment of the lower lobe of the left lung [7,10]. The findings in this case report are similar, with the anomalous vessel extending from the aorta distal to the ductal arch to the lower segment of the left lung.…”

“…Pulmonary sequestration is characterized by a lack of normal bronchial connections to the segment of the lungs supplied by the anomalous vessel. Anomalous systemic arterial supply to a normal segment of the lung (i.e., without sequestration) is a much rarer entity described in case reports in children [1][2][3][4][5][6] and adults [7][8][9][10][11]. This is previously classified as Pryce type I sequestration [12].…”

Isolated Systemic Supply to Normal Lung—A Rare Cause for Hemoptysis (A Case Report with Review of Literature)

“…Very rarely, there may be multiple feeding arteries. 11 The anomalous branches may not withstand high systemic pressures due to predominant elastic lamina (unlike muscular arteries) and hence tend to bleed, presenting as hemoptysis. 12 The high pressures may also cause thickening and calcification of the wall of the anomalous artery with aneurysm formation and development of stenosis, especially in elderly patients.…”

Transcatheter arterial embolization of anomalous systemic arterial supply to the basal segment of the lung

“…In most cases, this congenital abnormality appears in the left basal segment of the lung, and the anomalous artery is usually a single vessel arising from the left side of the descending thoracic aorta. Very rarely, the congenital abnormality is in the right basal segment of the lung (3,4), and is associated with two or more anomalous arteries that arises from the proximal abdominal aorta or the celiac trunk (3). As a result of improvements in diagnostic imaging technology, the existence of the anomalous artery, the absence of a normal pulmonary artery and a normal branch of the bronchus can all be demonstrated using only a chest CT. Angiography is also a very useful examination, which can evaluate the hemodynamic status and the presence or absence of a shunt.…”
