Effect of cold storage on immediate graft function in an experimental model of renal transplantation in cats.

OBJECTIVE To assess the effect of cold storage (CS) on immediate posttransplantation function of renal autografts in cats. ANIMALS 15 healthy 1-year-old cats. PROCEDURES Cats were assigned to 2 groups and underwent autotransplantation of the left kidney followed by nephrectomy of the right kidney.

An in-house phantom as an alternative to commercially available Doppler flow phantoms.

Learning the principles and application of Doppler ultrasound is difficult and requires repeated practice. Flow phantoms provide a method of teaching Doppler techniques before their application in clinical patients; however, commercially available flow phantoms are expensive. Herein we describe an easily constructed, economic Doppler flow phantom, utilizing readily available products, for use as a training aid.

Ultrasonographic determination of resistive index and graft size for evaluating clinical feline renal allografts.

Ultrasonographic examination is a commonly employed technique for postoperative renal allograft evaluation after transplantation. Allograft size and resistive index (RI) are two objective ultrasonographic measures that may help establish a diagnosis and direct postoperative management for grafts with suboptimal function but their diagnostic efficacy has not been evaluated in clinical veterinary patients. Results of 69 feline renal transplant ultrasonographic examinations and RI determinations were studied.

Correlation of ultrasonographic appearance of lesions and cytologic and histologic diagnoses in splenic aspirates from dogs and cats: 32 cases (2002-2005).

Objective: To determine the accuracy of cytologic diagnosis, compared with histologic diagnosis, in determination of disease in ultrasound-guided fine-needle aspirates of splenic lesions.

Design: Retrospective study.

Sample Population: Splenic specimens from 29 dogs and 3 cats.

Phenobarbital-responsive ptyalism, dysphagia, and apparent esophageal spasm in a German shepherd puppy.

A 10-week-old, male German shepherd dog was presented with a primary complaint of episodic ptyalism, dysphagia, vomiting, and mandibular salivary gland enlargement. An esophagram with fluoroscopy showed normal pharyngeal and esophageal function; however, upper gastrointestinal endoscopy and cervical ultrasonography revealed a focal circumferential thickening of the midcervical esophageal muscular wall, consistent with esophageal spasm. The puppy responded dramatically and completely to phenobarbital treatment.
