Minimally invasive surgery has been found in humans to reduce pain, incidence of infections, and duration of hospitalization. Minimally invasive procedures are also being described in veterinary medicine. Laparoscopic ovariohysterectomy (OHE) was performed on nine, healthy, intact female dogs using a Harmonic scalpel. Creatine kinase values were determined(More)
The purpose of this study was to evaluate the surgical outcomes of 28 dogs with generalized septic peritonitis treated without postoperative abdominal drainage. The overall mortality rate was 46%, with most cases of peritonitis being caused by leakage of the gastrointestinal tract (75%). Etiology of peritonitis, abdominal cytopathology, total white blood(More)
The tibial tuberosity advancement (TTA) procedure was developed to treat dogs with cranial cruciate ligament deficient stifles. A retrospective, descriptive study was performed on 57 dogs that underwent unilateral or bilateral TTA. Medical records were reviewed and pre-, postoperative and follow-up radiographs were evaluated for patellar ligament-tibial(More)
OBJECTIVE To compare the effects of postoperative pain after ovariohysterectomy by harmonic scalpel-assisted laparoscopy (HALO) and traditional ovariohysterectomy (OVH) in dogs. STUDY DESIGN A randomized, blinded, prospective study. SAMPLE POPULATION Sixteen, purpose-bred, intact female, Beagle dogs. METHODS Dogs were divided into 2 groups: Group 1 (8(More)
OBJECTIVE To assess the effect of 9 mm tibial tuberosity advancement (TTA) on cranial tibial translation (CTT) in a cranial cruciate ligament (CCL)-deficient canine stifle model. STUDY DESIGN In vitro cadaveric study. ANIMALS Canine pelvic limbs (n=12). METHODS Each stifle was placed in a jig at 135 degrees with a simulated quadriceps force and tibial(More)
Cementless total hip implants are relatively new to the veterinary market and therefore complication rates and prognostic indicators associated with the procedure have not been thoroughly documented. The objective of this study was to determine the prevalence of complications and identify prognostic indicators of success or failure for the Zurich cementless(More)
OBJECTIVE To assess the effects of epidural anesthesia using lidocaine on microcirculatory blood flow, volume, and velocity in free fasciocutaneous flaps in dogs. Study Design-In vivo experimental investigation. Animal Population-Ten adult dogs weighing 20 to 25 kg. METHODS A medial saphenous fasciocutaneous free flap was removed and an orthotopic(More)
The purpose of the anatomical study was to identify potential myoperitoneal microvascular free flaps, in dogs, that are based on a single artery and vein. The angiosomes of the right deep circumflex iliac artery and left phrenicoabdominal (cranial abdominal) artery were evaluated in six medium-sized canine cadavers. The right deep circumflex iliac artery(More)
The purpose of this study was to identify the angiosome of the medial saphenous artery and vein and to evaluate the use of this cutaneous angiosome as a free skin flap in the dog. In phase 1 of this study, selective angiography of the medial saphenous artery performed in six canine cadavers showed that the skin covering the entire medial femorotibial area,(More)
We evaluated the diagnostic sensitivity of ultrasound, nonenhanced computed tomography (CT) and nonenhanced magnetic resonance (MR) imaging in detecting wooden foreign bodies in the canine manus. Identical wooden splinters were manually inserted into 30 cadaver canine manus, and the limbs were evaluated using ultrasound, CT, and MR imaging by independent(More)
