Transsinusoidal portal vein embolization with ethylene vinyl alcohol copolymer (Onyx): a feasibility study in pigs.

Purpose: Portal vein embolization is performed to increase the future liver remnant before liver surgery in patients with liver malignancies. This study assesses the feasibility of a transsinusoidal approach for portal vein embolization (PVE) with the ethylene vinyl alcohol copolymer, Onyx.

Methods: Indirect portography through contrast injection in the cranial mesenteric artery was performed in eight healthy pigs.

Arterial head vascularization cartographies of normal metencephalic dogs using magnetic resonance angiography.

The aim of our study was to establish head arterial cartographies-useful for the diagnosis of brain diseases leading to cerebral vascular modifications-by means of magnetic resonance angiography (MRA). Casts of the arterial vascular brain system were used to corroborate the MRA results as they can be easily rotated in nonvirtual three-dimensions and give an accurate view of the arteries calibre and origin. Two types of 3T MRA images were used: three-dimensional fast low-angle shot (3D-FLASH) acquisition sequenced every 20 s, paired with injection of a paramagnetic contrast medium, and three-dimensional time-of-flight (3D-TOF) acquisition sequenced every 300 s.

Precision, reproducibility, and clinical usefulness of measuring the Norberg angle by means of computerized image analysis.

Objective: To evaluate the precision, reproducibility, and clinical usefulness of measuring the Norberg angle (NA) by means of a computerized system of image analysis.

Sample Population: 1,182 consecutive radiographs of hip joints of various breeds of dogs assessed for hip dysplasia and 72 radiographs of hip joints of German Shepherd Dogs.

Procedures: Radiographs were assessed by a panel of 4 experts in consensus, and NAs were measured by means of a computerized system.

Evaluation of computed tomographic anatomy of the equine metacarpophalangeal joint.

Objective: To determine the detailed computed tomography (CT) anatomy of the metacarpophalangeal (MCP) joint in healthy horses.

Sample Population: 10 cadaveric forelimbs from 10 adult horses without orthopedic disease.

Procedures: CT of the MCP joint was performed on 4 forelimbs.

Urodynamic and morphologic changes in the lower portion of the urogenital tract after administration of estriol alone and in combination with phenylpropanolamine in sexually intact and spayed female dogs.

Objective: To compare the urodynamic and morphologic effects of the administration of estriol alone and in combination with phenylpropanolamine on the lower portion of the urogenital tract in female dogs.

Animals: 3 sexually intact and 3 spayed female Beagles without urinary incontinence.

Procedure: Dogs received estriol (2 mg, PO) once daily for 7 days followed by estriol (2 mg, PO) and phenylpropanolamine (1.

Influence of the estrous cycle on urodynamic and morphometric measurements of the lower portion of the urogenital tract in dogs.

Objectives: To compare the values of the urodynamic parameters of the lower portion of the urinary tract and vaginourethral measurements obtained during the phases of the estrous cycle in dogs and determine possible functional or anatomic modifications of the lower portion of the urinary tract associated with those phases.

Animals: 7 adult female Beagles.

Procedure: Urethral pressure profilometry, diuresis cystometry, and vaginourethrography were performed in each dog during proestrus; estrus; early, mid, and late diestrus; and early and late anestrus.

Radiographic, magnetic resonance imaging, computed tomographic, and rhinoscopic features of nasal aspergillosis in dogs.

Objective: To determine radiographic, magnetic resonance imaging (MRI), computed tomography (CT), and rhinoscopic features of nasal aspergillosis in dogs.

Design: Prospective study.

Animals: 15 client-owned dogs.

Validation and comparison of the use of diuresis cystometry and retrograde filling cystometry at various infusion rates in female Beagle dogs.

Objectives: To compare retrograde filling cystometry at infusion rates of 5, 10, and 20 mL/min with diuresis cystometry for determination of an appropriate infusion rate and to confirm the reproducibility of measurements obtained by urethral pressure profilometry (UPP) and cystometry in female Beagles.

Animals: Adult female Beagles.

Procedure: Successive UPP and cystometry were performed by use of a water perfusion catheter on dogs anesthetized with propofol.

Computed tomographic findings in 35 dogs with nasal aspergillosis.

The purpose of this study was to describe the computed tomographic (CT) features of nasal aspergillosis in dogs. Initial (n = 35) and follow-up (n = 12) CT images were available from 35 dogs. The most commonly encountered CT findings were (1) moderate to severe cavitary destruction of the turbinates with presence of a variable amount of abnormal soft tissue in the nasal passages, (2) non-specific thickening of the mucosa adjacent to the inner surface of bones of the frontal sinus, maxillary recess and nasal cavity and, (3) thickened reactive bone.
