Assessment of subclinical venous catheter-related diseases in horses and associated risk factors. A total of 102 horses that had a catheter introduced intravenously to facilitate treatment had the catheterised jugular vein and contralateral vein examined by ultrasound every 48 hours. Subclinical complications were defined by thrombus formation or thickening of the venous wall, and the data were analysed to establish risk factors for the development of these complications. The horses with a rectal temperature above 38.5 degrees C when the catheter was introduced were four times more likely to develop complications, than the horses with a lower temperature. The administration of a NSAID whil...
Evaluation of polysulfated glycosaminoglycan or sodium hyaluronan administered intra-articularly for treatment of horses with experimentally induced osteoarthritis.

PCR detection of African horse sickness virus serogroup based on genome segment three sequence analysis. A nested reverse transcriptase (RT) polymerase chain reaction (RT-PCR), for rapid detection of African horse sickness virus (AHSV) double-stranded ribonucleic acid (dsRNA) in cell culture and tissue samples, was developed and evaluated. Using an outer pair of primers (P1 and P2), selected from genome segment three of AHSV serotype 6 (AHSV-6), the RT-PCR-based assay resulted in amplification of a 890 base pair (bp) primary PCR product. RNAs from the nine vaccine strains of AHSV, and a number of AHSV field isolates including the Central African isolates of AHSV-9 and AHSV-6, propagated in cell c...
Evaluation of an automated blood culture system for the isolation of bacteria from equine synovial fluid. The objective of this study was to evaluate an automated blood culture system for the isolation of microorganisms from infected equine synovial fluid (SF). Samples were collected from 220 severely inflamed synovial joints and classified as either presumably infected (group A: n=149) or not infected (group B: n=71), based on a combination of clinical history, clinical signs and cytological analysis of the SF. Samples were inoculated into blood culture bottles and after incubation were subcultured onto agar media to confirm the results and to facilitate full bacterial identification. Microorgani...
Successful treatment of a sinonasal cryptococcal granuloma in a horse. A 12-year-old 500-kg (1,100-lb) American Quarter Horse mare was evaluated because of chronic mucopurulent, bloody discharge from the left nostril, inspiratory dyspnea, and respiratory noise. Results: The horse had severe inspiratory dyspnea and stertorous respiration with no airflow from the left nostril. A temporary tracheostomy was performed. Endoscopy revealed a tan mass protruding from the left middle nasal meatus into the left common nasal meatus; it extended caudally into the nasopharynx and around the caudal edge of the nasal septum into the right nasal cavity. Radiographically, a soft ...
Use of computed tomography to diagnose new bone formation associated with desmitis of the proximal aspect of the suspensory ligament in third metacarpal or third metatarsal bones of three horses. 3 horses with lameness localized to the proximal aspect of the metacarpus or metatarsus. Results: All horses had evidence of problems that originated from the proximal aspect of the suspensory ligament (PASL), including signs of pain on palpation, positive results of diagnostic nerve blocks, ultrasonographic detection of enlargement and diffuse areas of reduced echogenicity in the proximal region of insertion of the ligament, and radiographic detection of increased mineral opacity in the proximal aspect of the metacarpus or metatarsus. Desmitis of the PASL was diagnosed in each horse; however,...
Colic: nonsurgical complications. Colic is a serious disease of the horse and may require surgical correction. Postoperative complications may result in an increase in short-term morbidity and mortality. Commonly encountered nonsurgical complications are detailed. Anticipation and timely treatment of common postoperative complications after colic surgery may improve overall survival.
Selected urogenital surgery concerns and complications. This article discusses selected urogenital surgeries. The discussion focuses on perioperative concerns and complications. The ideal approach to addressing complications resulting from disease processes or surgery is to avoid them. This approach requires knowledge of what can go wrong, gained by personal experience and that shared by others. The better one is able to anticipate potential complications, the more likely complications can be avoided.
Complications associated with equine arthroscopy. Arthroscopic complications are infrequent but when they occur can cause significant morbidity in the equine patient. This article reviews intraoperative and postoperative complications along with ways to avoid them. Additionally, therapeutic methods of managing these complications also are discussed.
Strategies for reducing the complication of orthopedic pain perioperatively. Equine orthopedic pain management has become a growing area of interest. Its importance has been emphasized in many studies showing that better pain management results in decreased postoperative complications such as chronic pain, support-limb laminitis, gastric ulceration, and gastrointestinal disease. This review is meant for the surgeon managing orthopedic pain pre-, peri-, and postoperatively.
Surgical complications of the equine upper respiratory tract. Upper respiratory abnormalities are common performance-limiting problems in horses. The complications of various treatment methods, including laryngoplasty surgery, sinus surgery, intermittent dorsal displacement of the soft palate, laser surgery, and tracheal disorders, are discussed.
Complications in equine anesthesia. General anesthesia of horses entails considerable risk of morbidity and mortality. A large-scale, multicenter study reported that the death rate from non-colic-related anesthetics was 0.9%, while the perianesthetic mortality rate at a single, busy equine surgical practice was somewhat more favorable, at 0.12%. While any perianesthetic death is devastating, mortality figures alone do not reflect the overall morbidity of equine anesthesia in terms of nonterminal events or injuries related to recovery. In some circumstances, recognition of perianesthetic complications may allow appropriate interv...
Surgical complications of colic surgery. Colic is one of the most common and challenging problems that equine practitioners encounter. Although the majority of horses with colic can be treated with medical management, up to 10% of horses with colic require surgical intervention. The decision for surgery is often straightforward based on historical and diagnostic information. However, some horses require further diagnostics and observation to determine if surgery is needed. Surgical intervention can be life saving. However, complications may arise during surgery, in the immediate postoperative period, or during long-term management, a...
Complications of ophthalmic surgery in the horse. Corneal transplantation, amniotic membrane transplantation, phacoemulsification cataract extraction, and laser glaucoma therapy are routine ophthalmic surgical procedures in horses. This article discusses the indications, techniques, and postoperative complications of these and other ophthalmic surgical procedures in horses. Meticulous and accurate anatomic repair can minimize postoperative complications to maintain positive visual outcomes in ophthalmic surgery of the horse.
Complications of surgery for diseases of the guttural pouch. Guttural pouch diseases pose serious challenges in diagnosis and treatment. Complications from treatment are common and often life-threatening, largely because the unique anatomy of the guttural pouches brings them into intimate contact with the nervous, respiratory, and cardiovascular systems. There is little forgiveness for surgical errors, and so the surgeon should focus on ways to anticipate and prevent them. As with any disease, errors in diagnosis can set the stage for many surgical errors and must be recognized. This article deals with errors that can be expected after the most common s...
Complications of orthopaedic surgery in horses. Complications are a price all surgeons eventually pay. Experience and increasing skill will decrease many of them but certainly not all. The most important thing is for the surgeon to react correctly to a complication. Acknowledge the mistake (or bad luck) quickly and take whatever steps you can to correct the problem. Because so many equine orthopaedic cases have the potential for complications, recognizing and responding properly to these complications are imperative for successful outcomes. Discussion of the most common complications, their prevention and corrections, is presented.
Complications of laparoscopic surgery. This article describes surgical complications associated with laparoscopy, how to avoid them, how to recognize them if they do happen, and how to deal with them in the most expedient method possible. Complications of sedation, anesthesia, positioning, the general surgical approach, and complications associated with specific surgical procedures are examined. The best defense against surgical complications is a thorough training program and an understanding of anatomy that will help the surgeon work in the three-dimensional environment while being limited to two dimensions on the monitor. The au...
Complications of equine oral surgery. The vast majority of equine oral procedures are dental-related and, unless great care is taken, almost all such procedures have the potential to cause marked short- or long-term damage to other oral structures. This review of the more common complications of oral surgery begins at the rostral oral cavity with procedures of the incisors, and then moves caudally to deal with complications related to procedures of wolf teeth and cheek teeth, including salivary duct disruption and dental sinusitis. Finally, complications associated with maxillary and mandibular fractures are discussed.
Analysis of local spread of equine influenza in the Park Ridge region of Queensland. In 2007, an incursion of equine influenza (EI) occurred in Australia. Accurate maps of property boundaries were used to examine the pattern and mechanism of local spread of EI. This study focussed on a cluster of infected premises (IPs) at Park Ridge, a peri-urban suburb 26 km south of Brisbane, Queensland. The cluster recorded 437 IPs and 81% of these were not contiguous to a previously IP. The mean distance from each new IP to the closest previous IP was 0.85 +/- 1.50 km with a range of 0.01-12.94 km. Eighty-two percent of new IPs were within 1 km of a previous IP. The spatial mean for each ...
Characterization of equine adipose tissue-derived progenitor cells before and after cryopreservation. In horses, stem cell therapies are a promising tool to the treatment of many injuries, which are common consequences of athletic endeavor, resulting in high morbidity and often compromising the performance. In spite of many advantages, the isolation of stem cells similar to human, from equine adipose tissue, occurred only recently. The aim of this study was to isolate equine adipose tissue-derived progenitor cells (eAT-PC), to characterize their proliferative potential, and to study their differentiation capacity before and after cryopreservation. The cells, isolated from horse adipose tissue,...
Characterization of alpha(4)beta(1) (CD49d/CD29) on equine leukocytes: potential utility of a potent alpha(4)beta(1) (CD49d/CD29) receptor antagonist in the treatment of equine heaves (recurrent airway obstruction). The purpose of this study was to characterize the alpha(4)beta(1) receptor (CD49d/CD29, very late antigen-4, VLA-4) on circulating equine leukocytes and to evaluate the intrinsic potency of an alpha(4)beta(1) receptor antagonist (Compound B) in the horse. Ultimately, these studies would allow us to determine the suitability of treating recurrent airway obstruction (RAO; heaves) affected horses by blocking the cellular recruitment of lymphocytes and neutrophils into the lung. The data demonstrates the alpha(4)beta(1) integrin is present on horse lymphocytes and neutrophils (fluorescence-assiste...
Twin pregnancy experimental model for transvaginal ultrasound-guided twin reduction in mares. Multiple pregnancies are still an important cause of noninfectious abortion, stillbirth, neonatal mortality, and significant delays in reproductive performance in mares. Despite new management techniques, reduction in multiple pregnancies is an ongoing preoccupation and challenge for the equine veterinarian. The aim of the present study was to establish a twin pregnancy experimental model in the mare to study the effectiveness of a transvaginal ultrasound-guided embryonic vesicle injection. Mares in heat were inseminated and then received an embryo at day 7 of the estrous cycle. At days 14 and...
