Desmotomy for treatment of chronic desmitis of the accessory ligament of the deep digital flexor tendon in a horse. Chronic lameness was determined to be caused by desmitis of the accessory ligament of the deep digital flexor tendon and adhesions associated with these 2 structures. Desmotomy of the accessory ligament, resection of adhesions, and controlled exercise during convalescence resulted in return to normal use without apparent lameness.
Multiple aneurysmal bone cysts in a foal. Multiple aneurysmal bone cysts (ABCs) are previously unreported in horses. An ABC was diagnosed in the left 3rd metacarpal of a Thoroughbred foal, which partially resolved following surgical curettage. A 2nd ABC developed in the left tibia, 7 wk postoperatively, and the foal was euthanized.
Pseudocyst of the spermatic cord of a gelding. Clinical, echographic, and histopathological features of an unusual enlarging scrotal mass in a 5-year-old gelding are described. Echography of the scrotal mass in this case provided valuable information concerning the nature of the tissue present, and assisted in narrowing the differential diagnosis.
Management of a transverse fracture in the distal phalanx of a horse. A yearling horse was presented with a septic, transverse fracture in the frontal plane of the distal phalanx. The fracture fragment was surgically removed from the parent bone via the sole. The foot was managed by corrective farriery and the horse was able to be ridden for pleasure.
Combination of medical and surgical therapy for pleuropneumonia in a horse. Medical management was unable to prevent the development of an extrapulmonary abscess in a 10-year-old Thoroughbred gelding with anaerobic pleuropneumonia. Intercostal thoracostomy achieved drainage of the abscess. Resolution of the abscess and subsequent bronchopleural fistulas was monitored by ultrasonography and video-endoscopy. The horse returned to training 4 mo after discharge.
Incomplete nasomaxillary dysplasia in a foal. Atresia of the nasal punctum is the most common congenital anomaly for the equine nasolacrimal system. Nasomaxillary dysplasia has not been previously documented in foals, is of unknown etiology, and appears to be a rare condition. Conjunctivomaxillary sinostomy was successful in resolving the epiphora.
Varices with thrombosis in the cervix and uterus of a mare. Cervical and uterine varices with thrombosis were observed at the necropsy of a virgin 16-year-old Peruvian Paso that had previous episodes of hemorrhage from the uterus. Practitioners and pathologists should be alert to the possibility of ruptured varices in mares with hemorrhage into the uterus or from the vulva.
Repair of a deep digital tendon deficit in a horse using a polypropylene implant. A yearling horse was treated for a chronic wound with a 4 cm deficit in the deep digital tendon. The gap in the tendon was bridged with paired polypropylene braided implants designed for use as a ligament augmentation device. Uncomplicated healing and return to function occurred.
Lag screw fixation of an extensor process fracture in a foal with flexural deformity. A 4-month-old colt with stage I flexural deformity of the distal interphalangeal joint was diagnosed as having a type IV nondisplaced fracture of the extensor process of the 3rd phalanx. An inferior check ligament desmotomy and internal fixation of the fracture were performed. Favorable long-term results for internal fixation of extensor process fractures are presented.
Pregnancies from imipramine and xylazine-induced ex copula ejaculation in a disabled stallion. Breeding or semen collection was attempted using: natural cover, manual stimulation, artificial vagina, pharmacologic induction of ejaculation, and electroejaculation. Sperm cells were recovered from the ductus deferens and epididymides post mortem. Only semen collected ex copula by imipramine and xylazine treatment resulted in conceptions (4/5). This is the first report of pregnancies in horses from ex copula semen collection.
Removal of a nasal polyp in a standing horse. Diagnosis and removal of a nasal polyp in a horse using standing chemical restraint and readily available equipment are described. Histopathology of the polyp and differential diagnoses are discussed.
A comparison of romifidine and xylazine when used with diazepam/ketamine for short duration anesthesia in the horse. The purpose of this study was to compare and evaluate sedation with intravenous xylazine (1.1 mg/kg bodyweight [BW]) versus intravenous romifidine (100 micrograms/kg BW) followed by induction of anesthesia with intravenous diazepam (0.04 mg/kg BW) and ketamine (2.2 mg/kg BW). Twelve healthy horses were used in a blinded, randomized, cross-over design. Heart rate, presence of 2nd degree atrioventricular heart blocks (2 degrees AVB), respiratory rate, arterial blood pressures, blood gases, packed cell volume, total serum proteins, and duration of anesthesia and recumbency were recorded. Inductio...
A case-control study of the congenital hypothyroidism and dysmaturity syndrome of foals. A case-control study was conducted to identify risk factors for the congenital hypothyroidism and dysmaturity syndrome of foals. A questionnaire was used during personal interviews of foal owners and farm managers to collect information on animal signalment, farm environment, and mare management. Information on 39 foals with the congenital hypothyroidism and dysmaturity syndrome were compared with 39 control foals. Foals with the syndrome had a significantly (P < 0.0001) longer gestation (357.6 d) than control foals (338.9 d). Pregnant mares that were fed greenfeed, did not receive any supplem...
Comparison of herniorrhaphy versus clamping of umbilical hernias in horses: a retrospective study of 93 cases (1982-1994). Many uncomplicated umbilical hernias have been managed successfully in foals by the application of a hernia clamp. Isolated reports of complications following clamp application have led some authors to suggest that it is an unsuitable method of treatment. Little information has been published comparing the complication rates associated with the use of hernia clamps and herniorrhaphy in the treatment of umbilical hernias. The purpose of this retrospective study was to report the characteristics of clinical cases of umbilical hernia and to compare the complication rates following these 2 treatme...
Tissue and serum concentrations of amikacin after intramuscular and intrauterine administration to mares in estrus. Concentrations of amikacin in endometrial tissue and plasma were studied in mares in estrus after intrauterine infusion of 1.0 or 2.0 g once a day for 3 consecutive d, and after 9.7 or 14.5 mg/kg body weight (BW) had been injected intramuscularly once a day for 3 consecutive d to determine concentrations of amikacin sulfate in plasma and endometrial tissues, and whether parenteral administration provides any advantages over intramuscular infusion. No amikacin was detected in serum at the 1.0 g dose. At the infusion dose of 2.0 g once a day, very low levels of serum amikacin were detected at 1 ...
