That systemic artery is usually large, originating from the thoracic aorta or the abdominal aorta and its upper branches. We describe a case of ILS where a large systemic artery coming up from below the diaphragm is formed by the convergence of many very small serpiginous arteries coming up from the area of the celiac trunk and common hepatic artery: a kind of “rete mirabile”. This peculiar morphology was not described before.展开更多
