<unk>  of the ductus arteriosus is a rare entity in adults The ductus arteriosus is a short tubular connection between the left pulmonary artery and aorta. A remnant of the left sixth aortic arch, it normally undergoes physiologic closure soon after birth. In the few reports of<unk> s involving a patent ductus arteriosus in adults, it is uncertain whether the ductus arteriosus recanalized or original patency persisted. Normal closure proceeds from the pulmonary artery to the aortic end. Therefore, when closure is incomplete, the pulmonary side closes and the aortic side remains patent. 60% fatality rate due to complications rupture (i.e. dissection, infection, and distal embolization occur) Criteria for resection include lesions greater than 3 cm in diameter, symptomatic<unk> s, and any that show progressive enlargement.
