Intravenous administration of an ionic radiographic contrast medium was believed to have caused acute oliguric renal failure in a young dog. Intravenous pyelography was done on a healthy 14-month-old female Lhasa Apso prior to reconstructive surgery for pseudohermaphroditism. Within 24 hours of the radiographic procedure, acute oliguric renal failure developed. Cause for the renal failure was not found other than the recent IV administration of radiographic contrast medium. Treatment with fluids, furosemide, and dopamine was successful in returning renal function to normal. Various adverse reactions to IV administration of contrast media in human beings and animals have been reported; however, to our knowledge, acute renal dysfunction induced by IV administration of contrast material has not been reported in dogs

Postoperative survival and early complications after intracranial surgery in dogs

Objective To describe survival and early postoperative outcome after intracranial surgery in dogs. Study design Retrospective case series. Animals Fifty client-owned dogs that underwent intracranial surgery. Methods Records were searched and analyzed for dogs that underwent intracranial surgery between 2005 and 2015. Signalment, clinical presentation, neurological deficits, concurrent medical conditions, laboratory data, diagnosis, administration of perioperative glucocorticoids or antiepileptic drugs, and specific imaging, surgical, and anesthetic variables were recorded. Risk factors for survival, occurrence of postoperative complications, and hospitalization times were identified with univariate linear and logistic regression, followed by multivariable regression models. Results All dogs were recovered with a specific protocol in an intensive care unit. Forty-nine of 50 (98%) dogs survived the immediate postoperative period, and 46 of 50 (92%) survived to discharge. Early postoperative neurological deterioration was seen in 45% (22/49) of dogs, and a postoperative complication was diagnosed in 23 of 49 (47%). Nonneurological postoperative complications were seen in 9 of 49 (18%) dogs; the most common consisted of aspiration pneumonia (6/49, 12%). Among variables associated with outcomes, higher postoperative natremia (P?=?.023) and prolonged hospitalization (P?=?.024) were associated with the occurrence of postoperative, nonneurological complications. Conclusion The short-term survival rate of this population was excellent. About half of the dogs experienced neurologic deterioration and postoperative complications, and most resolved with treatment. Clinical significance In our clinical setting, intracranial surgery in dogs was associated with a high rate of survival and a low rate of severe postoperative complications
