Elective procedures

Elective procedures are those performed on a non-emergency basis, and which do not involve immediately life-threatening conditions. These are in contrast to emergency procedures.


Sterilization surgery

One of the most common elective surgical procedures in animals are those that render animals incapable of reproducing. Neutering in animals describes spaying or castration (also please see

in cattle, sheep, and goats. These procedures have been controversial and recently debated among breeders, veterinary organizations, and animal welfare scientists. The controversy is different for each procedure, but issues arise based on reasons to perform the procedure, differing opinions on techniques and methods, perceived long-term benefits in individual animals, and the development of alternatives.

Cardiology surgery

Common cardiology surgeries in animals include: * Balloon valvuloplasty: Procedure used to alleviate pain symptoms from cardiac problems such as pulmonic, mitral, and tricuspid stenosis. The purpose of this procedure is to create a smoother blood flow throughout the body by reducing harmful effects from obstructed heart valves. It is considered a minimally invasive procedure. The procedure involves putting a balloon-like object inside of the animal's heart; the balloon inflates and deflates in order to alleviate pain and increase blood flow. Complications can occur if the animal's body rejects the balloon, forming a life-threatening allergic reaction. * Centesis: Procedure consisting of the removal of fluid from an animal's body in order to manage congestive heart failure. Draining fluid helps prevent tumors from growing around the heart. Animals undergo no anesthesia because little pain occurs during this operation. Catheters and needles of various sizes are punctured into the thoracic cavity. To remove the fluid, veterinarians will use a syringe suction or vacuum. Post-operatively, swelling might occur around the thoracic cavity or appear bruised, but this is normal and is rarely discomforting to the animal. * Devive Embolization of Persistent Ductus Arteriosus (PDA): PDA is caused by an abnormal blood flow from right to left inside the heart. This causes patients to develop left-sided congestive heart failure. In order to treat this condition, coils are placed inside ducts of the heart. The coils embolize into the pulmonary arteries. Both the ACDO device and the procedure itself are relatively inexpensive.
