Topic:Veterinary Procedure
Veterinary procedures in horses encompass a range of medical and surgical interventions performed to diagnose, treat, and manage equine health conditions. These procedures are designed to address various health issues, from routine care to emergency interventions. Common veterinary procedures include vaccinations, dental care, lameness evaluations, reproductive services, and surgical interventions such as colic surgery or fracture repair. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, outcomes, and advancements in veterinary procedures for horses, providing insights into their application and efficacy in equine medicine.
[The immobilization of wild equines with STH 2130 and tiletamine/zolazepam]. Successful immobilisation of Przewalski's horses and zebras was obtained by using a combination of STH 2130 (Boehringer) and Tiletamin/Zolazepam.
Surgery of the upper respiratory tract in the racehorse. The authors discuss the surgical treatment of selected diseases of the upper airway of the racehorse. Although most of these conditions occur commonly and are easily diagnosed, their surgical management is often less straight-forward and may be surprisingly controversial. The authors' intent is to provide an overview of these problems and give some information regarding current treatment options.
Traumatic disruption of the suspensory apparatus in foals. Traumatic disruption of the suspensory apparatus is a catastrophic injury in the horse. Although this injury has been described in the adult, little information is available in the foal. This paper describes 3 foals with metacarpophalangeal joint instability caused by traumatic disruption of the suspensory apparatus. Two foals had biaxial proximal sesamoid fractures in a single forelimb, and 1 foal had avulsion of the distal sesamoidean ligaments in 1 forelimb plus biaxial proximal sesamoid fractures in the other forelimb. The foals with single forelimb involvement were managed with splints, a...
Anatomy of the laryngeal and adjacent regions as perceived by palpation of clinically normal standing horses. The anatomy of each feature and structure of the laryngeal and adjacent regions, as perceived by palpation, is described for clinically normal standing horses. Visible skin contours produced by some of the superficial structures are also described. Concurrent dissection was performed on fresh cadavers to confirm initial findings. The procedure of systematic palpation in relation to clinical diagnosis and surgical procedure is discussed.
[Endodontics in horses. An experimental study]. A total of 44 experimental endodontic treatments were performed in incisors of eight horses of different ages. Four different endodontic pastes were used: Cloropercha, AH26 De Trey, Eugenol-Endometasone, and Universal N2. Gutta-percha points were also included in the last two treatments. Access to the pulp cavity of incisors was gained through their vestibular and occlusal faces. Holes drilled in vestibular faces were sealed with composite and those drilled in occlusal faces were sealed with Amalgama. Animals were observed during eighteen months at least after endodontics. Radiographic control...
[Veterinary examinations of horses during purchase transactions]. Veterinary examinations of horses on the occasion of sale or purchase take place on the basis of contracts for work and services. Three types may be distinguished: Examinations for sale (by order of the seller before the sales contract is concluded) Guarantee examination (by order of the buyer after conclusion of the sales contract) (Real) purchase examination (under a conditional contract of purchase). In the latter case the veterinarian acts as trustee for both seller and buyer and is equally obliged to both parties morally and at law. The deficiencies of the law of warranties for contracts ...
Lameness diagnosis and treatment in the Standardbred racehorse. Lameness of the Standardbred racehorse is a function of rigorous training programs, year-round racing schedules, hard racetrack surfaces, and the draft load. In this article, principles of lameness diagnosis and treatment are reviewed, with emphasis upon common or unique problems of the trotter and pacer. The role of physical therapy as an adjunct to medical and surgical treatment of lameness is described. Options for management of chronic pain are discussed, and a limited glossary of descriptive terms that are unique to harness racing is provided.
Tracheal obstructions in two horses and a donkey. The clinical signs associated with intramural tracheal obstructions in two horses and a donkey were respiratory distress and coughing, which were aggravated by exercise and excitement. The obstructions were at the level of the thoracic inlet and consisted either of flattening of the cartilage rings in the dorsoventral plane or of cartilage rings having a scroll-like conformation. They appeared to be developmental in origin and to have been present for a considerable time before the onset of clinical signs. Endoscopy and radiography were helpful in the diagnosis of the condition.
Surgical repair of tibial tuberosity avulsion fractures in four horses. Four horses, 2 to 17 years old, were treated for unilateral avulsion fractures of the tibial tuberosity. Two horses were treated successfully with tension band wiring or plating in combination with lag screw fixation. One horse was euthanatized because of implant failure during recovery and one was euthanatized on day 11 because a longitudinal fracture of the tibial tuberosity occurred through the plane of the screws used for stabilization.
Evaluation of an interfragmentary compression system for the repair of equine femoral capital physeal fractures. Femoral neck and proximal epiphyseal lengths were measured in 37 femurs from 19 cadaver foals that were 1 day to 12 months old to determine the applicability of a human interfragmentary compression system to equine femoral capital physeal fractures. Because components of the implant system are available only in fixed sizes, its use was possible in foals older than 5 weeks of age, but not in younger foals. The 135 degree angle plate conformed best to the equine femur. Femoral capital physeal fractures were created surgically and repaired with the implant system in three foals. Fracture stabilit...
Effects of left recurrent laryngeal neurectomy, prosthetic laryngoplasty, and subtotal arytenoidectomy on upper airway pressure during maximal exertion. Upper airway pressure was measured with a nasotracheal catheter system and a portable pressure transducer in 10 normal horses during maximal exercise before and after left recurrent laryngeal neurectomy. Measurements were repeated 16 weeks after prosthetic laryngoplasty (5 horses) or subtotal arytenoidectomy (5 horses). During maximal exertion, prosthetic laryngoplasty was more effective than subtotal arytenoidectomy in reversing the increases in upper airway pressure that followed left recurrent laryngeal neurectomy.
Arthroscopic approaches and intraarticular anatomy of the equine elbow. Periarticular anatomy and techniques for arthroscopic access to the equine elbow were studied in six joints from cadavers. Caudomedial and craniolateral approaches were evaluated subsequently in 11 anesthetized horses. The caudomedial approach was made between the flexor carpi radialis and flexor carpi ulnaris muscle bellies. Most of the caudal articular surfaces of the humeral condyles, the caudal perimeter of the radius, and the trochlear notch and portions of the anconeal process of the ulna could be identified. The voluminous caudal joint capsule cul-de-sac proximal to the anconeal process...
Mechanical properties of four suture patterns for transected equine tendon repair. Thirty-six superficial digital flexor tendons from nine fresh equine cadavers were transected and sutured with size 2 monofilament nylon. Nine tendons were repaired with each of four suture patterns: single-locking loop, double-locking loop, triple-locking loop, or three-loop pulley. The times required for application, tensile strengths, resistance to distraction (gap), and modes of failure were analyzed. The mean times required were: single-locking loop, 3 mins, 15 secs; double-locking loop, 4 mins, 15 secs; triple-locking loop, 10 mins, 50 secs; and three-loop pulley, 4 mins. The double-lock...
A large frontonasal bone flap for sinus surgery in the horse. A large frontonasal bone flap was created to treat diseases of the paranasal sinuses in 14 horses. The bone flap was made as wide as possible within the confines of the nasolacrimal duct so the floor of the frontal sinus and the dorsal and ventral conchae could be opened. These openings exposed the nasal passages, maxillary sinuses, and ventral conchal sinus thereby facilitating removal of diffuse and localized lesions from these sites. Diseases treated were ethmoid hematomas (4 horses), sinus cysts (5 horses), cryptococcal granuloma, osteoma, hemangiosarcoma, pus in the ventral conchal sinus,...
Intraocular silicone prostheses in a dog and a horse with corneal lacerations. Intraocular silicone prostheses were implanted in the eyes of a horse and a dog with traumatic corneal lacerations and protrusion of intraocular contents. Several months after surgery, the horse and dog were tolerating the intraocular prostheses, and the appearance was cosmetically acceptable. This contradicts earlier reports that have cited corneal disease as a contraindication for implantation of intraocular silicone prostheses.
Pericarditis in horses: six cases (1982-1986). Records of 6 horses with pericarditis were reviewed. Septic pericarditis was suspected in all horses, based on historic and clinical findings. In horses 1, 2, and 4, cytologic examination of the pericardial effusion revealed acute inflammation with severe neutrophil degeneration. In horses 3 and 5, cytologic examination of pericardial fluid revealed subacute inflammation with degenerated neutrophils, and in horse 6, chronic active inflammation, with well preserved neutrophils. In horses 1 and 3, bacteria were identified on cytologic examination of pericardial fluid. Results of microbiologic cu...
Bilateral congenital cysts in the frontal sinuses of a horse. Congenital frontal sinus cysts were found bilaterally in the frontal sinuses of a one-year-old miniature horse. Diagnosis was based on radiography of the head and cytologic examination of tissue aspirated from the frontal sinuses. The cysts were surgically removed, using a hinged bone flap technique bilaterally over the frontal sinuses.
Anatomy of the dorsoscapular ligament of horses. Thoracic limbs from 8 horses were dissected. The dorsoscapular ligament was determined to consist of a collagenous part that fused to the surface of the thoracolumbar fascia and of an elastic part that extended laterally from the collagenous part to attach to the medial surface of the scapula and interdigitate with fibers of the serratus ventralis thoracis muscle.
Endometrial concentrations of ampicillin in mares after intrauterine infusion of the drug. Serum concentration of ampicillin, a semisynthetic penicillin, was measured in mares at various time intervals up to 24 hours after intrauterine infusion of 3 g of ampicillin. Blood samples were drawn immediately before infusion and at 1-, 4-, 10- and 24-hour intervals after infusion. At postinfusion hour 24, two endometrial biopsy specimens were obtained to measure endometrial concentrations of ampicillin. Blood was drawn twice as part of the 24-hour postinfusion sample collection, once before removal of the biopsy specimens and again 5 minutes after removal of the biopsy specimens. After dru...
Long-term jugular vein catheterization in horses. The use of soft catheter materials in large-bore veins has allowed safe long-term venous access in human patients. Similar principles were applied to groups of horses; the jugular vein was catheterized for 14 days (group 1) and for 30 days (group 2). Three catheter materials were compared, and the clinical and histologic findings indicated that the least reaction was associated with silastic, followed by polyurethane; polytetraflouroethylene caused marked reaction. Our results suggest that by using catheters made of materials (especially silastic) that are less stiff or rigid, the duration of ...
Carbon dioxide laser ablation for treatment of limbal squamous cell carcinoma in horses. Limbal squamous cell carcinoma in 4 horses was treated successfully, using carbon dioxide laser ablation. Tumors were removed, with minimal to no postoperative inflammation or discomfort to the horses. Carbon dioxide laser ablation represents a promising new option in the treatment of limbal squamous cell carcinoma in horses.
Twenty cases of equine osteoarthrosis detected at autopsy. A pathological study was performed on osteoarthrosis detected at autopsy in 20 horses whose ages ranged from 21 days to 17 years old. They were asymptomatic on the joints except in 3 animals, and autopsied after death or sacrificed due to accidental fracture or other diseases. Lesions of osteoarthrosis were recognized in all horses, which tended to increase in incidence and severity according to age. Lesions were concentrated at hinged joints such as the elbow, fetlock, and hock. Synovial fossae and ulcerative lesions were observed on each opposite articular cartilage, forming the so-called mi...
Autoimmune haemolytic anaemia in eight horses. Autoimmune haemolytic anaemia was diagnosed in eight horses on the basis of a positive Coomb's test. The disease was considered to be idiopathic in three cases and secondary to another condition in five. The clinical signs included dullness and depression, pyrexia, jaundice and haemoglobinuria. In addition to anaemia, haematological evaluation commonly revealed auto-agglutination of red cells and anisocytosis; reticulocytosis and an increased mean corpuscular volume were less commonly observed. Four horses were successfully treated with dexamethasone, but the other four were destroyed or died ...
Diagnostic ultrasonography for evaluation of cryptorchidism in horses. The location and size of 11 retained testes were accurately determined ultrasonographically. There was 100% correlation between the location of the testis determined by ultrasound vs that determined by surgery. Testicular size determined presurgically in all cases closely approximated the actual size obtained by gross measurement of the excised testis. The cryptorchid testicular echotexture was less dense than that of the normal descended testicles, but was easily identified. Ultrasonographic evaluations were completed by use of an ultrasound base unit with attached 5-MHz transrectal transduce...
