[Spontaneous aneurysm of the patent ductus arteriosus with endarteritis. A case report]

The spontaneous aneurysm of the ductus arteriosus is an extremely rare disease. From a total of 24 adult cases reported in the literature up to 1987, only in one case the ductus was open and other, was recanalized after being closed. We described the second case in the literature in a patient with totally permeable ductus arteriosus who developed a spontaneous aneurysm and endarteritis, showing the great importance of the diagnostic procedures such as echocardiogram, tomography and angiogram, as well as the surgical treatment which was successful in our patient. The probable etiology of this disease is discussed.
