Chronic Visceral Artery Obstruction Associated with Hypoplastic Aorta in a Pair of Monozygotic Twins

We report a case of chronic visceral artery obstruction associated with a hypoplastic aorta in a pair of monozygotic twins. They had suffered from abdominal angina and intermittent claudication. The younger twin underwent simultaneous visceral artery reconstruction and right common iliac-femoral artery bypass at age 30. The older twin underwent a visceral artery reconstruction at age 34, 4 years after bilateral common iliac-femoral artery bypass. We used a temporary shunt in order to ensure perfusion for the visceral organs, because there was a rich collateral circulation to visceral organs from the inferior mesenteric artery (IMA) and the internal iliac arteries.
