Calcification of patent ductus arteriosus

Calcification of patent ductus arteriosus Brief Review Abstract: Calcified patent ductus arteriosus (PDA) produces an inverted Y shaped pattern of calcification on x-ray chest PA view. Detection of calcification of the patent ductus arteriosus is important because of potential problems with surgical management. The simple surgery for closure of patent ductus arteriosus was triple ligation which was a closed heart procedure not requiring cardiopulmonary bypass. But a calcified ductus cannot be dealt with by this procedure. The general dictum is that a calcified ductus needs division and ligation with support of cardiopulmonary bypass. This is more likely to be needed in adult patients. Now device closure is being undertaken even in cases of calcified ductus. Of the twenty one adult patients reported by Bonhoeffer P and associates, the ductus was calcified in seven patients.1 Calcification of a patent ductus arteriosus has been reported by several authors in relatively young patients.2,3,4 Calcification of an obliterated ductus arteriosus or ligamentum arteriosus can also occur. This may be noted as an incidental finding on computerized tomographic imaging of the thorax.5 X-ray appearance of calcification of patent ductus arteriosus Typical appearance of calcification of patent ductus arteriosus in an X-ray chest PA view is inverted Y shaped. Inverted Y shape is a combined appearance of calcification of the aortic arch extending down to the pulmonary artery and patent ductus...
