“…Isolation of the carotid artery is a rare form of aortic arch anomaly, with only 15 cases reported thus far (Table 1). [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] All except one case had a right aortic arch with an isolated left carotid artery. 14 In three patients, only the internal carotid artery was isolated, and the external carotid artery was arising from the aorta (8,11,14).…”

“…Coexisting CHD by altering pulmonary artery pressure, however, modifies the flow pattern. For instance, in conditions with reduced pulmonary blood flow, the isolated carotid artery is a source of pulmonary blood flow, thus alleviating arterial desaturation 11 . In others with pulmonary hypertension, depending upon relative resistances in systemic and pulmonary circulation, the isolated arch vessel may decompress the pulmonary circulation by allowing right to left shunt and manifesting as differential cyanosis.…”

Isolated left common carotid artery: multidisciplinary management is the key to success

An isolated carotid artery is a rare aortic arch anomaly. Instead of connecting to the aorta, the isolated carotid artery connects anomalously to the pulmonary artery. Chronically altered cerebral circulation poses the risk of cerebral hyperaemia following surgical reimplantation. We describe successful reimplantation of the isolated left common carotid artery in a child, highlighting the importance of a multidisciplinary approach for good clinical and neurological outcomes. We also briefly discuss the embryologic basis of this rare arch anomaly.

“…Significant associated congenital cardiac defects were also often present in cases with isolated left common carotid artery from the pulmonary artery: primum atrial septal defect, 5 secundum atrial septal defect, tetralogy of Fallot, 6 persistent left supra vena cava, 7 aortic atresia, 8 Ebstein anomaly, 4 CHARGE syndrome, 1 , 4 DiGeorge syndrome, 9 or hemifacial abnormality 7 . Our case had anovulvar fistula, without any other abnormality including coloboma, genital anomaly, and ear abnormality, and she had normal karyotype and fluorescence in situ hybridisation result for 22q11 deletion.…”

The closing process of the ductus arteriosus connecting the left common carotid artery and main pulmonary artery

2019

View full text Add to dashboard Cite

An isolated left common carotid artery is very rare, and only 13 cases have been reported thus far. All those cases were accompanied by a right aortic arch and aberrant left subclavian artery, and the connecting vessel between the pulmonary artery and left common carotid artery was thought to be ductal tissue. However, there have been no reports that have followed the natural closure of this vessel. We present a case in whom we could observe the closing process of this vessel at the connection between the left common carotid artery and main pulmonary artery in association with a tetralogy of Fallot.

Isolation of right internal carotid artery, persistent proatlantal 1 artery and rete mirabile in a child with 22q11 deletion syndrome

et al. 2018

View full text Add to dashboard Cite

We report a case of a 2-year-old girl with 22q11 deletion syndrome who underwent studies for cardiac murmur. Ultrasound, computed tomography angiography and digital subtraction angiography revealed an aberrant right subclavian artery and an isolated right internal carotid artery (ICA) originating from the right pulmonary artery. A right carotid rete mirabile (CRM) and a proatlantal (Pa) type 1 artery were also found. We hypothesize that Pa type 1 persistence and CRM development are secondary to the reversal of flow of the isolated ICA.
