Objective: To report complications in dogs with naturally occurring cranial cruciate ligament rupture following single-stage bilateral tibial tuberosity advancement (SS-BTTA) procedures, and to compare these complications to a population of dogs undergoing unilateral tibial tuberosity advancement (UTTA). Methods: Medical records and radiographs of client-owned dogs treated with tibial tuberosity advancement between August 2008 and December 2011 were reviewed. Forty-four client-owned dogs with bilateral cranial cruciate ligament rupture that underwent SS-BTTA procedures and 82 clientowned dogs that underwent UTTA procedures were randomly selected from our hospital population. Complications were recorded and analysed. Major complications were defined as fractures or any complication requiring a second surgery. Minor complications were any problem identified that did not require surgical management. Results: Incidence for major and minor complications in the UTTA group was 2.3% and 24.4%, respectively. Incidence for major and minor complications in the SS-BTTA group was 12.5% and 26.1%, respectively. Singlestage bilateral tibial tuberosity advancement procedures had a four- to five-fold increase in odds of a major complication (p <0.050) compared to UTTA. Clinical significance: The findings of our study indicate that SS-BTTA procedures are associated with an increased risk of major complications compared to UTTA procedures. © Schattauer 2015. Source

Objectives: To prospectively compare the accuracy of three preoperative measurement techniques in tibial plateau levelling osteo - tomy (TPLO) planning. Methods: Fifty-nine dogs were randomly assigned to one of three measurement techniques; A, B or C. Surgeons measured the intended osteotomy location on preoperative radiographs according to the assigned technique. Measurements were used intra-operatively during osteotomy placement. Postoperative measurements were made by a single blinded observer and compared to preoperative measurements. Results: Fifty-one dogs were included for final statistical analysis. The mean absolute differences between pre- and postoperative measurements was 1.72 mm ± 0.958, 1.79 mm ± 1.010, and 3.56 mm ± 1.839, for techniques A, B and C, respectively. No significant differences were identified for patient age, gender, limb or surgeon. Techniques A and B were not significantly different (p = 0.8799). Techniques A and B were significantly more accurate than C (p = 0.0001 and p = 0.0003, respectively). Weight was significantly different among the groups (p = 0.047) but the statistical results did not change when an adjustment was made for bodyweight (p = 0.4971, p <0.001 and p = 0.0007, respectively). Clinical significance: Preoperative measuring for planning a TPLO osteotomy is recommended. Techniques A and B in the current study were clinically practical and significantly more accurate compared to technique C. © 2015 Schattauer. Source

A 10-week-old domestic shorthair kitten was referred for intermittent episodes of dyspnea, cyanosis and a suspected congenital thoracic anomaly. Physical examination showed an obvious palpable concavity in the caudal thoracic spine. Thoracic radiographs showed severe caudal thoracic lordosis from T5 to T13 with a Cobb angle of -77°, a centroid lordosis angle of -68°, a vertebral index of 6.3 and a flattened sternum. Severe loss of vital capacity was suspected and surgical correction of the thoracic deformity was to be performed in two separate stages, the first being surgical ventral distraction on the sternum to increase thoracic volume and rigid fixation with an external splint. The second stage, if required, would be surgical correction of the spinal deformity to also increase thoracic volume. The initial stage of surgery was performed and postoperative radiographs showed a vertebral index of 10.3. The kitten suffered a left sided pneumothorax in recovery and died from cardiorespiratory arrest despite immediate pleural drainage and cardiopulmonary resuscitation. Treatment recommendations that may benefit future case management are discussed. © ISFM and AAFP 2014. Source

This study evaluated segmental measurement techniques for predicting immediate post-deployment intraluminal tracheal stent length in dogs with naturally occurring tracheal collapse. Radiographs of 12 client-owned dogs that underwent intraluminal tracheal stent placement were retrospectively reviewed. Tracheal lengths were divided into 1, 2, 3, or 4 equal segments. Stent lengths were predicted using the widest dorsoventral height of each segment, with and without the addition of 10%, and an accompanying foreshortening chart. Techniques were compared for intra- and inter-observer reliability, and post-deployment stent length predictability. There was good to high intra- and inter-observer reliability for all segmental measurements; median intra-class correlation coefficients were 0.98 and 0.92, respectively. Measuring 2 segments without the addition of 10% to the widths was significantly more accurate in predicting immediate post-deployment stent length in terms of percent (P = 0.03) and absolute difference (P = 0.02). Segmental measuring techniques are repeatable amongst observers and may help guide stent selection. Source

An 11-year-old spayed female pit bull terrier was presented with a 2-month history of polyuria, polydipsia, polyphagia, and panting. Serum chemistry, blood and urine analysis, and tests for hyperadrenocorticism suggested an adrenal tumor. Abdominal ultrasound identified a mass caudal to the right kidney. The mass was completely excised and histopathology was consistent with endocrine carcinoma. Three years later there was no evidence of recurrence or metastasis. Source
