Operative management of the calcified patent ductus arteriosus
JP Gold and LH Cohn
A technique in which the calcified adult patent ductus arteriosus can be
safely divided using a left-sided thoracotomy approach without the need for
transient aortic cross-clamping or cardiopulmonary bypass is described.
Concentric, nested vascular clamps are placed on the noncalcified pulmonary
artery side of the ductus, so that dissection and clamping of the heavily
calcified ductus-aortic junction are unnecessary. The pulmonary artery rim
surrounding the insertion of the ductus can be divided between the two
clamps and oversewn.
