1. Cheramie, Hoyt Stephen. Occlusion of the Internal Carotid Artery of Horses: Evaluation of a Technique Designed to Prevent Epistaxis Caused by Guttural Pouch Mycosis.

Degree: MS, Veterinary Medical Sciences, 1998, Virginia Tech

In six, healthy, adult horses, the origin of the left internal carotid artery was isolated via a modified hyovertebrotomy approach. Normograde blood flow was occluded by placement of a tourniquet on the artery near its origin. Lumenal access was gained through placement of a distally directed introducer sheath and retrograde blood flow from the cerebral arterial circle was confirmed. An 8.5 mm diameter detachable latex balloon loaded onto a carrier catheter and placed within a guiding catheter was introduced into the internal carotid artery through the introducer sheath and advanced to the target occlusion site (the proximal curve of the sigmoid flexure of the internal carotid artery). The balloon was inflated with 0.5 ml of a radiopaque solution. Correct placement and inflation of the balloon were confirmed by intraoperative radiography. The balloon was then released and the guiding and carrier catheters withdrawn. Immediate embolization of the distal internal carotid artery was determined by lack of retrograde blood flow through the introducer sheath. The introducer sheath was withdrawn from the vessel and the proximal tourniquet was replaced with two ligatures. Horses were euthanized on day 30 and detailed gross and histopathologic examinations were performed. The balloons were easily placed into the target site and produced immediate occlusion of retrograde flow from the cerebral arterial circle. All balloons remained inflated in their original position throughout the study period. Mature thrombus formation and absence of clinically significant inflammation were consistent findings in all occluded internal carotid arteries at gross necropsy and histologic examination.

2. Sysel, Annette M. Investigation into the use of an epidural morphine sulfate and detomidine hydrochloride combination in horses: Part 1: efficacy in alleviation of hindlimb pain, Part 2: long-term systemic and local effects.

Degree: MS, Veterinary Medical Sciences, 1996, Virginia Tech

In Part 1, amphotericin B-induced synovitis of the left tarsocrural joint was used to create hindlimb lameness in 11 horses. Caudal epidural catheters were placed and advanced to the lumbosacral region. Baseline heart and respiratory rates were recorded and horses were videotaped at a walk and trot. Treated horses received 0.2 mg/kg morphine sulfate and 30 ug/kg detomidine hydrochloride through the epidural catheter; control horses received an equivalent volume of physiologic saline solution through the catheter. At hourly intervals after epidural injection for a total of 6 hours, heart and respiratory rates were recorded and horses were videotaped walking and trotting. At the end of the observation period, video recordings were scrambled onto a master videotape. Lamenesses were scored by 3 investigators. Lameness grades, heart rates and respiratory rates were compared. There was a significant decrease in lameness grades after treatment with epidural morphine and detomidine. Initially, heart rates significantly increased in control horses and decreased in treated horses. A similar trend occurred for respiratory rates. In Part 2, caudal epidural catheters were used to administer injections to 10 horses every 12 hours for 14 days. Treated horses received 0.2 nlg/kg morphine sulfate and 30 ug/kg detomidine hydrochloride, and control horses received an equivalent volume of physiologic saline solution. Body weights were recorded on days 1 and 14. Rectal temperature, heart rate, respiratory rate and gastrointestinal motility were recorded twice daily, and daily hay and water consumption was measured. Horses were euthanatized day 15. Atlanto-occipital cerebrospinal fluid samples were submitted for bacteriologic culture and determination of white and red blood cell counts and protein and glucose concentrations. Post mortem examinations were performed and representative samples of the spinal cord and surrounding tissues were taken from cervicothoracic, thoracolumbar, lumbosacral, sacral and catheter entry point regions. Spinal tissue segments from these regions were graded for histologic degree of inflammation and fibrosis. Cerebrospinal fluid values and spinal tissue segment inflammation and fibrosis grades were compared between control and treated horses, and between all 10 catheterized study horses and 6 uncatheterized horses. No problems were encountered with epidural catheter maintenance or injection. No significant difference was identified in body weight change, daily variables or hay and water consumption between control and treated horses. All cerebrospinal fluid cultures were negative for growth. No significant difference in cerebrospinal fluid values or spinal tissue inflammation or fibrosis grades for any segment was demonstrated between control and treated horses. However, when compared to uncatheterized horses, cerebrospinal fluid red blood cell counts were marginally higher and protein concentrations were significantly higher in catheterized horses. As well, lumbosacral and… Advisors/Committee Members: Pleasant, Robert Scott (committeechair), Jacobson, John D. (committee member), Moll, H. David (committee member), Sponenberg, D.

3. May, Kimberly Anne. Experimental Evaluation of Urinary Bladder Marsupialization in Male Goats.

Degree: MS, Veterinary Medical Sciences, 1999, Virginia Tech

Urinary bladder marsupialization has been successful in producing acceptable long-term resolution of clinical cases of obstructive urolithiasis in male goats. The purpose of this study was to evaluate the six-month outcome of urinary bladder marsupialization in male goats. The urinary bladders of six male goats free from systemic disease were marsupialized following induced urethral obstruction. Renal ultrasonography, complete blood count, and blood chemistry analysis were evaluated preoperatively (day 0), at 7 postoperative days, and at 30-day intervals until 180 postoperative days. Stomal diameter was recorded at each interval. Necropsy examination was performed on day 180 or when stomal stricture or death occurred. Stomal stricture occurred in one goat at 120 days, and another goat was found dead at 150 days. Necropsy of this goat revealed severe, suppurative cystitis. All goats developed mild urine scald dermatitis. All blood chemistry values remained within normal limits. Significant decreases in white blood cell count, serum creatinine, and stomal diameter were observed from day 0 to day 180. Except for the goat that died at 150 days, all urinary bladders were tubular in shape and the mucosa and serosa of all urinary tract organs appeared grossly normal at necropsy examination. Histologic evidence of chronic suppurative cystitis and chronic, mild, lymphoplasmacytic pyelitis was present in all goats. Culture of renal tissue yielded bacterial growth in three of six goats, and culture of a swab of the urinary bladder mucosa yielded bacterial growth in all animals. Although clinical signs of ascending urinary tract infection were not observed in goats with patent stomata, urinary bladder marsupialization may result in ascending inflammation or infection. Based upon the results of this study, urinary bladder marsupialization should be recommended with caution as the primary procedure in clinical cases. Advisors/Committee Members: Moll, H. David (committeechair), Larson, Martha Moon (committee member), Duncan, Robert B. Jr. (committee member), Howard, Rick Dale (committee member), Pleasant, Robert Scott (committee member).
