At VCA ASG, we know pets are family. When a dog experiences a slipped or ruptured spinal disc (IVDD), it can be painful and sometimes life-altering. That’s why we offer advanced options like PLDA to help reduce the risk of future disc problems and support long-term comfort and mobility.
Intervertebral Disc Disease (IVDD) occurs when the cushioning discs between the bones of the spine become damaged or rupture, potentially putting pressure on the spinal cord. After one episode, dogs have a 20–50% risk of recurrence, with higher risk in breeds such as dachshunds, Staffordshire terriers, beagles, basset hounds, and French bulldogs.
Percutaneous Laser Disc Ablation (PLDA) is a minimally invasive procedure designed to reduce the risk of future disc herniation.
It works by reducing the central disc material (nucleus pulposus), which is most likely to rupture. Studies show recurrence risk may be reduced to as low as 4–5% in appropriate cases.
PLDA may be recommended for dogs who have recovered from a prior IVDD episode and are neurologically stable, or for high-risk breeds identified through imaging or history.
It is not an emergency treatment and is not a substitute for surgery in dogs with paralysis or severe neurologic decline.
Under general anesthesia, small needles are placed into selected discs using imaging guidance. A medical laser is used to reduce disc material inside the disc space, helping stabilize it and reduce the risk of future rupture. The procedure is minimally invasive and does not require a large surgical incision.
Before PLDA, the patient will undergo a full evaluation with Dr. Biegen, including:
Some medications (such as steroids or anti-inflammatories) may need to be paused before the procedure. Our neurology team will guide pet owners through this carefully.
