Percutaneous Laser Disc Ablation (PLDA)

Veterinary Percutaneous Laser Disc Ablation Services in San Diego, CA


Minimally Invasive Proactive Procedure for IVDD

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.

What is IVDD?

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.

What is PLDA?

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.

Who May Benefit from PLDA?

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.

How Procedure is Performed

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.

What to Expect Pre-Procedure

Before PLDA, the patient will undergo a full evaluation with Dr. Biegen, including:

  • Physical and neurologic examination
  • Pre-anesthetic bloodwork
  • Review of prior imaging (MRI/CT if available)
  • Discussion with owner of benefits, risks, and individualized recommendations

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.

Key Benefits of PLDA

  • Minimally invasive procedure
  • No large surgical incision
  • Helps reduce risk of future disc herniation
  • Short recovery time compared to traditional surgery
  • Can be used preventively in high-risk dogs

Important Considerations

  • PLDA does not treat active spinal cord compression emergencies
  • It is most effective in dogs that have recovered or are stable after IVDD
  • Not all discs are treated - Dr. Biegen will determine the safest and most appropriate plan for the patient.
