We report a case of aortic arch reconstruction with an autologous pulmonary arterial-roll tube in a 4-year-old child with a type A interrupted aortic arch. The autologous pulmonary arterial-roll tube dilated progressively after the operation, and some severe complications occurred, including formation of an aneurysm. A second operation was performed to resect the aortic aneurysm and to interpose a Dacron tube graft. We conclude that the aforementioned dilation may limit the use of an autologous pulmonary arterial-roll tube in the construction of the aortic arch.
