We are of the view that the accurate prospective radiological reporting of this anomaly is important, especially in the context of endovascular stent procedures of aortic arch lesions, as the left subclavian artery perfusion would in such cases depend on the subclavian steal phenomenon from a normal left vertebral artery.
The steal phenomenon caused by ALCAPA causes significant left ventricular myocardial compromise and is associated with a high morbidity in infants.
They believed that in their patients focal hypoperfusion due to steal phenomenon resulted in dystrophic subcortical calcification.
One hypothesis that can explain exertional symptoms is steal phenomenon. This phenomenon results from increased metabolic demands in the LCX territory resulting in ischemic changes in LAD or RCA territories mimicking an acute coronary event [1, 2].
It was previously thought that caudal regression syndrome and sirenomelia were manifestations of the same syndrome, but it seems that syrenomelia is the result of vascular steal phenomenon that causes severe ischaemia of the caudal portion of the fetus.
