Willow is a gorgeous 3 month old Weimaraner who presented to us with PDA (Patent Ductus Arteriosus) which is an abnormal vessel at the base of the heart allowing too much blood to re-circulate through the lungs. The vessel is patent throughout foetal life but should close by three days of age. If the vessel remains open, allowing abnormal shunting of blood, progressive heart enlargement and heart failure can occur. In Willow’s case she required surgery to correct the problem. This involved ligating (tying off) the ductus arteriosus with suture material, thus routing all of the blood flow through the lungs. Once closed, the heart is returned to normal function, and generally an excellent prognosis can be offered. Willow’s surgery went really well and her owner reports that she is living a happy and healthy life almost one year on. Southpaws specialist surgeons have years of training and expertise in soft tissue surgery and have performed thousands of successful operations on dogs and cats and puppies and kittens. Soft tissue surgery can include surgery in the gastrointestinal, respiratory and genitourinary systems and includes surgical oncology in treating cancer.
