PDA (patent ductus arteriosus)
Meet Quey. This little man had a surgery for PDA (patent ductus arteriosus) a month ago (elsewhere) that unfortunately was not successful.
Quey presented for surgery yesterday for a second attempt, which is a very risky procedure due to adhesions and risk for fatal hemorrhage. True to that risk, surgery was very difficult. The cranial portion of the cranial left lung lobe was adhered to the body wall and heart and was so fragile it crumbled with manipulation and was removed. The caudal portion likewise was adhered but was left in place obscuring half the thorax and the heart.
With PDA surgery, the largest risk is for fatal hemorrhage from the fragile ductus, but on a 2nd surgery this risk is much higher. For little Quey, we were within a hair's breadth of successfully passing a clamp around the duct when it ruptured. Though this is usually fatal and results in rapid massive bloodloss, we were able to clamp off along the pulmonary artery and aorta and stop the hemorrhage. With conversion to an alternate technique dropping a loop of suture around the aorta, a 2nd massive rupture developed and for the second time l truly thought that was the end.
Miraculously with clamping a portion of the pulmonary artery and a thank you to the fates, we were able to once again stop the hemorrhage. The anesthesia service were rock stars, as was my assistant in the face of that much stress and how difficult the surgery was, but l am absolutely delighted to report that Quey miraculously survived. Special thanks to the critical care and emergency services post op. We needed packed red blood cells and 2 rounds of plasma, but today Quey is recovering and looking good!
Quey is in foster care with the North Central Maltese Rescue and is looking for a loving home for the dog with two angels on his shoulder. This rescue has been hit hard recently with multiple PDA surgeries, liver shunt surgeries and an eye surgery for their rescues and would welcome and appreciate any support. They are very caring and have rescued innumerous dogs over the years. -Dr. Connie Hurley Malteserescue.homestead.com
