The modified proportional margins system resulted in satisfactory local disease control in dogs with MCTs.

Objective: To report the incidence of postattenuation seizures (PAS) in dogs that underwent single congenital extrahepatic portosystemic shunt (cEHPSS) attenuation and to compare incidence of PAS in dogs that either did or did not receive prophylactic treatment with levetiracetam (LEV). Study design: Multi-institutional retrospective study. Population: Nine hundred forty dogs. Methods: Medical records were reviewed to identify dogs that underwent surgical attenuation of a single cEHPSS from January 2005 through July 2017 and developed PAS within 7 days postoperatively. Dogs were divided into 3 groups: no LEV (LEV−); LEV at ≥15 mg/kg every 8 hours for ≥24 hours preoperatively or a 60 mg/kg intravenous loading dose perioperatively, followed by ≥15 mg/kg every 8 hours postoperatively (LEV1); and LEV at <15 mg/kg every 8 hours, for <24 hours preoperatively, or continued at <15 mg/kg every 8 hours postoperatively (LEV2).Preliminary results of this study were presented at the Association

Pretreatment neutrophil-to-lymphocyte ratio and albumin-to globulin ratio may aid with diagnosis and optimal treatment planning. Further investigation into their prognostic implications is warranted.

Objective: To identify prognostic factors for short-term survival of dogs that experienced seizures within seven days following surgical correction of single congenital extrahepatic portosystemic shunts (cEHPSS).Study Design: Multi-institutional retrospective study. Sample Population: Ninety-three client-owned dogs. Methods: Medical records at 14 veterinary institutions were reviewed to identify dogs that underwent surgical attenuation of a single cEHPSS from January 1 st 2005 through February 28 th 2018 and experienced post-attenuation seizures (PAS) within seven days postoperatively. Logistic regression analysis was performed to identify factors associated with one month survival. Factors investigated included participating institution, signalment, shunt morphology, concurrent/historical conditions, presence of preoperative neurologic signs, presence of preoperative seizures, aspects of preoperative medical management, surgical details including method and degree of shunt attenuation, type of PAS (focal only or generalized +/-focal), drugs administered as part of the treatment of PAS, and development of complications during treatment of PAS. Results: Thirty (32.3%) dogs survived to 30 days. Seventy-six (81.7%) dogs experienced generalized PAS. Factors positively associated with short-term survival included having a history of preoperative seizures (p=0.004) and development of focal PAS only (p=0.0003).The majority of non-survivors were humanely euthanized due to uncontrolled or recurrent seizures.Conclusions: Dogs that experienced PAS that had a history of preoperative seizures and those that experienced focal PAS only had significantly improved short-term survival. Clinical Significance:The results of this study will help in the counseling of owners who seek treatment for PAS following surgical correction of cEHPSS.

An adenocarcinoma of the uterine stump with abdominal metastases is described in a 12-year-old incompletely ovariohysterectomised female Domestic Short Haired (DSH) cat. At the time of presentation the adenocarcinoma had metastasised to the right peri-renal lymph node, the abdominal aorta, and the right ureter, resulting in the formation of a large cystic structure. This had compressed and displaced surrounding structures including the abdominal vena cava and the right kidney, and formed multiple adhesions to the body wall and adjacent abdominal structures. Metastatic extension to the aorta had resulted in its regression into a 2mm diameter non-pulsatile vessel.

Complications may be encountered following surgical pancreatic biopsy, although the risk should be minimal with good surgical technique. Pancreatic biopsy may provide a useful contribution to case management but it is not clear whether a negative pancreatic biopsy should be used to rule out pancreatic disease. Dogs were more likely to have no significant pathology found on pancreatic biopsy than cats, where chronic pancreatitis was the most common finding.

Two dogs were presented with dermal arteritis of the nasal philtrum associated with repeated episodes of bleeding. Described treatment for this condition consists of long-term, usually life-long medication with various combinations of immune suppressant and anti-inflammatory medication. This paper describes a novel surgical approach to the condition that induced long-term remission in both cases.
