Transcatheter, Occlusion Of Patent Ductus Arteriosis Using Rashkind’s Umbrella Device
Keywords:Transcatheter, Occlusion Of Patent Ductus Arteriosis Using Rashkind’s Umbrella Device
Transcatheter occlusion of PDA using Rashkind’s Umbrella device is a popular method of PDA closure in the first world today. We performed our first successful closure on 20.9.1994 at AFIC/NIHD, Rawalpindi.
Ductus arteriosis is an aiterial connection between the descending aorta (just distal to the origin of the left subclavian artery) and the left pulmonary artery close to its origin. It closes within few hours to few weeks from birth. It causes increased left to right shunt and predisposes to volume overload of the heart, infections, infective endocarditis and to calcification, aneurysm formation and even rupture at late stages. Except when PDA is part of congenital cyanotic heart disease and helping the duct dependent circulation, the PDA has to be closed, and depending on clinical urgency various methods are employed such as intrav enous Indomethacin, or surgical intervention like ligation or duct interruption.
