While in veterinary school she received a number of awards including GPSA Travel Award, Richland Kennel Club Scholarship, George G. Ross Scholarship, and was the Mark Morris Student representative. She then proceeded to do a rotating internship at Colorado State University School of Veterinary Medicine followed by a 3-year small animal surgical residency at the University of California, Davis. She completed her surgery board examinations in 2004, at which time she became a Diplomate of the American College of Veterinary Surgeons. She was recruited to stay on an additional year after her residency at UC Davis for a fellowship in renal transplantation and vascular surgery, After completing the fellowship she was accepted for a tenure-track faculty position at the UC Davis Small Animal Surgery department. She remained in a UC Davis Small Animal Surgery faculty position as an assistant professor training students and residents, predominantly in soft tissue and oncologic surgeries from 2005-2008. She was the section leader for the Educational Commission for Foreign Veterinary Graduates Clinical Proficiency Exam from 2004-2008. Dr. Mehl has published numerous research papers in peer-reviewed journals and acquired many grants for her research. Her research specialized in kidney transplantation, liver shunt surgery, ureteral surgery and immunosuppression therapy. In 2008, she left her faculty position at UC Davis and came to San Francisco Veterinary Specialists (SFVS) where she has been working for the past 9 years performing a multitude of surgeries. She continues to author book chapters and is frequently invited to review research papers in her field of expertise.

Survival Analysis of One Versus Two Treatments of Local Delivery Cisplatin in a Biodegradable Polymer for Osteosarcoma

Abstract: The purpose of this study was to evaluate one versus two doses of local delivery cisplatin in a biodegradable polymer (OPLA-Pt) for the treatment of osteosarcoma (OSA) after amputation in dogs. Medical records were reviewed retrospectively, and 105 dogs were included in the study; 39% of dogs received one treatment (surgical implantation) of OPLA-Pt and 61% of dogs received two treatments of OPLA-Pt after amputation. Administration of two doses of OPLA-Pt did not have a significant effect on disease-free interval or survival time compared to one dose. The anatomic site of the tumour was identified as a prognostic factor, and dogs with proximal humeral OSA had the shortest disease-free interval and survival times. There was no advantage to giving a second dose of local delivery cisplatin following amputation for the treatment of OSA in dogs.

What Is A Board Certified Veterinary Surgeon? A board certified veterinary surgeon is a licensed veterinarian who has obtained intensive, additional surgical training. A veterinary surgeon can offer special assistance in the following kinds of cases:
  • Traumatic injury and emergencies such as fractures, skin wounds and lacerations, correction of gastric dilatation-volvulus, and exploratory (abdominal/thoracic) surgery
  • Orthopedic surgeries (such as total hip replacements (THRs), cruciate ligament surgeries (TPLOs), and arthroscopy for joint exploration).
  • Soft tissue surgeries (such as tumor/cancer removal and correction of congenital defects).
  • Neurological surgeries (such as herniated discs and spinal injuries).

While your general practitioner veterinarian can diagnose and treat many health problems, certain diseases and conditions require the care of a doctor who has had specialized, intensive surgical training in order to provide the very best outcome for your pet. Your veterinary surgeon will work closely with your general practitioner veterinarian, as well as'"depending on your pet's condition'"other board certified specialists in internal medicine, veterinary oncology, veterinary neurology, and veterinary radiology.

Why Does My Pet Need A Veterinary Surgeon?

Just as your own primary care physician may feel the need to refer you to the care of a specialist from time to time, your general practitioner veterinarian may feel your pet needs the additional expertise of a board certified surgeon for certain surgeries. In fact, many general practitioner veterinarians refer all but the most routine of surgeries to specialists'"orthopedic and neurology cases, reconstructive surgeries, tumor removals, etc.

Board certified veterinary surgeons also are often affiliated with referral hospitals where they may have access to specialized diagnostic or surgical equipment, the latest and safest anesthesia monitoring equipment, physical therapy or rehabilitation capabilities, and other critical care services that a general practitioner may not have access to. All of these specialized services may be necessary for the optimal care and recovery of your pet.

You can be assured that a veterinarian who knows when to refer you and your pet to a veterinary surgeon is one that is caring and committed to ensuring that your pet receives the highest standard of care for his or her problem.

What Kinds of Problems Require the Expertise of a Veterinary Surgeon?

Board certified veterinary surgeons can repair complex fractures, perform total hip replacements, and use advanced techniques to repair torn ligaments (ruptured cruciate ligaments) within the knee. They can also remove cancerous growths, manage extensive or non-healing wounds, and perform reconstructive surgery, such as grafting skin over large injuries. Veterinary surgeons can perform intricate surgeries in the chest or abdomen, such as kidney transplants in cats or repairing heart defects in dogs. Spinal injuries and herniated discs are problems that are also commonly referred to board certified surgeons. Veterinary surgery is also expanding into minimally invasive surgery, such as arthroscopy, thorascopy, and laparoscopy.

Will My Regular Veterinarian Still Be Involved?

In many if not most surgical cases, your regular veterinarian will still supervise your pet's veterinary care, especially if your pet is continuing to cope with a disease or chronic condition. It depends on your pet's particular disease and health problem, however. Typically, though, your general practitioner veterinarian will oversee many aspects of your pet's pre-op and post-op care, just as in human medicine. Recovery periods are often prolonged in many surgical cases, particularly in orthopedic surgery, and it is very important to follow your veterinary team's recommendations concerning at-home recovery guidelines for your pet, follow up care and appointments, as well as any rehabilitation that has been prescribed.

Did You Know?

Just as in humans, a pet's recovery from veterinary surgery can go more smoothly or even result in a better outcome with the addition of rehabilitation options. Many veterinary referral hospitals offer rehabilitation services, such as water therapy, physical therapy, and massage therapy, as an adjunct to surgical care.

Just as in people, laser surgery is becoming a much more common surgical technique in veterinary medicine, bringing with it the same advantages of reduced blood loss and shorter recovery times.

If you think that your pet may be a candidate for veterinary surgery, talk to your general practitioner veterinarian, or find a board certified veterinary surgeon near you today.
