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)
3.5 locking compression plate (LCP) fixation was compared to 3.5 limited contact dynamic compression plate (LC-DCP) fixation in a canine cadaveric, distal humeral metaphyseal gap model. Thirty paired humeri from adult, large breed dogs were separated into equal groups based on testing: static compression, cyclic compression, and cyclic torsion. Humeral(More)
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 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 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)
Introduction Irreversible electroporation (IRE) is a promising technique for the focal treatment of pathologic tissues that involves placing minimally invasive electrodes within the targeted region. A series of short, intense electric pulses are then applied to destabilize the cell membrane, presumably by creating nanopores, inducing cell death in a(More)
Non-invasive blood perfusion measurement systems have been developed and tested in a phantom tissue and an animal model. The probes use a small sensor with a laminated flat thermocouple to measure the heat transfer and temperature response to an arbitrary thermal event (convective or conductive) imposed on the tissue surface. Blood perfusion and thermal(More)
Accurate pre-operative localization and removal of disc material are important for minimizing morbidity in dogs with thoracolumbar disc extrusions. Computed tomography (CT) is an established technique for localizing disc extrusions in dogs, however the effect of multi-planar reformatting (MPR) on surgeon diagnostic performance has not been previously(More)
To evaluate the relationship between endostatin and vascular endothelial growth factor (VEGF) in cancers of dogs, circulating concentrations of these 2 tumor-associated markers were measured prospectively in healthy dogs (n = 44), dogs with tumors (n = 54), and dogs with nonneoplastic diseases (n = 42 for endostatin; n = 16 for VEGF). A canine-directed(More)
There are several disease processes of the ear and pinna that warrant surgical intervention. This article reviews surgical anatomy and common surgical procedures of the ear and pinna, including aural hematomas, lateral wall resection, vertical ear canal resection, total ear canal ablation and lateral bulla osteotomy, partial pinna resection, and feline(More)
