Welcome to The Veterinary Internal Medicine Group (VIMG), Miami’s trusted resource for expert veterinary diagnostic procedures, including abdominocentesis, thoracocentesis, and pericardiocentesis, provided by a board-certified specialist.

Abdominocentesis, thoracocentesis, and pericardiocentesis are specialized veterinary procedures that help diagnose and treat critical conditions in dogs and cats. These procedures safely remove excess fluid from a pet’s abdomen, chest cavity, or the sac around the heart.
This not only provides immediate relief but also enables your veterinary team to analyze the fluid for underlying causes such as infection, cancer, trauma, or heart disease. Timely diagnosis is essential for guiding the right treatment and improving your pet’s comfort and outcomes.
At The Veterinary Internal Medicine Group, we recognize how stressful it can be when a beloved pet is seriously ill. Led by Dr. Armstrong, a board-certified small animal internal medicine specialist, our team brings advanced diagnostic capabilities directly to the Miami community.
We combine medical precision with empathy, ensuring your pet receives personalized, compassionate care at every step. These procedures are performed with safety and comfort as top priorities.
When your pet is referred for a veterinary diagnostic procedure in Miami, our process is designed to maximize safety, comfort, and clarity for you and your pet.
We begin with a thorough evaluation to understand your pet’s history, symptoms, and current health status. You’ll stay informed at every stage, and our team will walk you through what to expect, including how we ensure your pet’s comfort throughout the visit.
Our veterinarians start with a detailed physical examination and review of your pet's medical history and symptoms. Dr. Armstrong prefers to involve owners during this stage to help alleviate anxiety for both you and your pet.
Diagnostic imaging, such as ultrasound or X-ray, may be recommended to pinpoint the exact location and amount of fluid. This ensures the safest and most effective approach for the procedure.
Once we confirm that a procedure is necessary, your pet is made as comfortable as possible. Fur in the targeted area may be shaved, and the skin is thoroughly cleansed. Sedation or local anesthesia is considered on a case-by-case basis to minimize stress and discomfort.
Our veterinary professionals use sterile technique and gentle restraint at all times. You are welcome to remain present during preparation when possible.
Using ultrasound guidance when indicated, our team carefully inserts a fine sterile needle or catheter into the appropriate area, abdomen, chest, or heart sac, to withdraw excess fluid. The amount of fluid removed varies depending on the clinical situation.
We immediately analyze samples in-house or send them to a laboratory for diagnostic testing. Removing the fluid often relieves your pet’s symptoms and allows for more comfortable breathing or movement.
After the procedure, your pet is closely monitored for any changes or complications. Our team provides detailed recommendations based on the fluid analysis and your pet’s overall status.
Dr. Armstrong will discuss findings with you in real time and answer all your questions. Our goal is to deliver prompt results and actionable recommendations to support the best outcome.

Procedures like abdominocentesis, thoracocentesis, and pericardiocentesis can be lifesaving for pets in urgent need. They bring immediate relief from dangerous fluid build-up and help diagnose the root causes of serious illness.
