Ischaemic distal limb necrosis and Klebsiella pneumoniae infection associated with arterial catheterisation in a cat.

This case report describes dorsal pedal arterial thrombosis and infection with Klebsiella pneumoniae subsequent to arterial catheter placement in a cat. The complication led to avascular necrosis of the metatarsal and pedal soft tissue. The catheter was placed for blood pressure monitoring during surgery for correction of a peritoneopericardial diaphragmatic hernia.

MRI findings of a middle ear cholesteatoma in a dog.

This article describes the MRI features of a middle ear cholesteatoma in an 8 yr old flat-coated retriever. Physical examination revealed pain on opening the jaw, and otoscopic examination showed tympanic membrane rupture associated with hyperplastic tissue at the entrance of the middle ear. Standard MRI sequences allowed for the identification of a severely expanded bulla containing material that was isointense to brain tissue on T1-weighted images and of mixed intensity on T2-weighted and fluid-attenuated inversion recovery sequences.

Alfaxalone for total intravenous anaesthesia in dogs undergoing ovariohysterectomy: a comparison of premedication with acepromazine or dexmedetomidine.

Objective: To describe alfaxalone total intravenous anaesthesia (TIVA) following premedication with buprenorphine and either acepromazine (ACP) or dexmedetomidine (DEX) in bitches undergoing ovariohysterectomy.

Study Design: Prospective, randomised, clinical study.

Animals: Thirty-eight healthy female dogs.

Canine sacroiliac luxation: anatomic study of the craniocaudal articular surface angulation of the sacrum to define a safe corridor in the dorsal plane for placement of screws used for fixation in lag fashion.

Objective: To define a safe corridor in the dorsal plane relative to the articular surface for placement of a single screw in lag fashion to achieve stabilization of sacroiliac luxation in the dog.

Study Design: Cadaveric study.

Methods: Dorsoventral radiographs of denuded canine sacra (n=49) were taken to determine the safe corridor in the craniocaudal plane, and the maximum, optimum and minimum angles were calculated that would allow a screw inserted in lag fashion to engage at least 60% of the width of the sacral body without cranial or caudal penetration through the bone.
