Laminite crônica em equino - tratamento com uso de ferradura com travessa horizontal e massa epóxi / Chronic laminitis in a horse - treatment with use of horseshoe with horizontal cross and epoxy putty

Background: Laminitis is characterized by an inflammation of the laminar structures of the hoof, which results in lamellar degradation of the suspensory apparatus of the distal phalanx. Despite being a common disease in the equine clinic, it is a medical emergency, which can lead the affected animals not return to sports activities. Due to the severity of laminitis and the poor prognosis, the objective was to report the case of a horse with chronic laminitis with sole perforation in all limbs treated with therapeutic shoeing using a type of horseshoe that has a horizontal crossbar and is filled with mass. Fast-drying epoxy, which has its use little described in the literature Case: A 4-year-old Crioula horse, weighing 325 kg, used in long noose competitions, was referred to the Veterinary Hospital of UFPR with chronic laminitis. The animal had reluctance to move, walk on a trestle position, grade V lameness and phalanx rotation of all limbs. The treatment of laminitis was carried out in the field, for two months, which consisted of trimming and shoeing with a horseshoe in the shape of a heart, and due to the failure of the treatment instituted, the patient presented clinical worsening. The treatment in the HV consisted of cleaning the perforated region of the sole with hydrogen peroxide and 10% iodine and dressing with cotton boots with EVA rubber on the sole to provide comfort. Corrective trimming was performed in order to remove excess forceps, lower the heel, and align the distal phalanx with the hoof wall, using a rasp. Orthopedic shoeing was performed with a normal horseshoe with a horizontal crossbar in the central region. The sole was filled with a quick-drying epoxy putty (Poxilina®), with the aim of preventing sole movement, blocking the rotation of the phalanges and improving the concavity of the hoof. Discussion: In chronic laminitis, the signs observed are claudication and deformation of the hoof, flat sole, enlargement of the white line, uneven growth of the hoof wall, hemorrhage in the abaxial white line, cracks in the hoof wall, which are observed parallel to the coronary band, in addition to phalanx rotation; in this clinical case, all these signs were observed. The trimming of horses with laminitis consists of removing the heels and decreasing the dorsal wall of the hoof, in this case, the trimming performed improved the clinical improvement of the animal five days after the procedure. The horseshoe used in the treatment of this animal has the objective of creating a weight-bearing surface on the middle of the sole, close to the tip of the frog, in this way the weight is not on the supporting edge of the clamp and, in this way, it reduces the pressure. over the most affected area. Despite the scarcity of reports on the use of this type of horseshoe, in this case it played a fundamental role in the treatment of laminitis. In this way, it is an alternative that must be taken into account when choosing the treatment, in view of its effectiveness and lower cost when compared to other methods. This case demonstrates the severity of laminitis in all limbs, especially as it presents a perforation of the sole. It is important to highlight that trimming and shoeing performed at the recommended interval (30-45 days) contributes a lot to the success of the treatment and the return of the animal to sports practice. The horseshoe with a horizontal crossbar was effective in the treatment of chronic laminitis of the forelimbs and pelvic limbs in the reported animal, with progressive improvement of the patient who returned to normal daily activities, without the presence of signs of pain or signs of laminitis after treatment.

Correção de deformidade flexural da articulação metacarpofalangeana em uma bezerra / Correction of flexural deformity of the metacarpophalangeal joint in a calf

Background: The congenital flexural deformity is common in cattle, often affecting the metacarpophalangeal joint of thethoracic limbs. The deformity may be mild, moderate, or severe, and the therapy depends on the limb’s degree of flexionand the affected joint. In severe deformities, tenotomy of the flexor tendons and desmotomy of the suspensor ligament isrecommended. However, this surgical technique may not be sufficient to promote limb extension, and other interventionsmay be necessary. Thus, the purpose of this report is to describe a technique to correct severe flexural deformities of themetacarpophalangeal joint in calves.Case: A 3-month-old, female, Dutch-bred calf weighing 46 kg was referred for treatment of congenital flexural deformity.On attendance, the patient presented severe deformity in the right thoracic limb and mild in the left thoracic limb both at theheight of the metacarpophalangeal joints. During palpation it was possible to notice that the flexor tendons were contractedin both limbs. Radiographic exams were performed to rule out the presence of other diseases, confirming the diagnosis offlexural deformity. The patient was referred to surgery to correct the anatomical anomaly. The animal was submitted to general anesthesia and placed in right lateral decubitus. In the left thoracic limb, an incision was made in the medial region ofthe metacarpal bone, the tissues were divulsioned until the superficial digital and deep digital flexor tendons were exposed;these structures were sectioned with a scalpel, and the limb was extended, returning to the standard anatomical position. Inthe right thoracic limb, the same procedure was performed, but during the limb extension test, we observed that the limbremained flexed, we then followed with a second incision and section of the deep...

Salpingopharyngeus fistula by means of videosurgery to treat horse bilateral gutural pouch chronic empyema – a case study / Fístula salpingofaríngea por videocirurgia para tratamento de empiema crônico de bolsa gutural bilateral em equino – relato de caso

The aim of this paper is to report the Salpingopharyngeus fistula technique by means of videosurgery through a natural orifice (NOTES) in order to treat bilateral empyema. A mare was seen at the Large Animal Sector of UFPR, with a history of bilateral purulent nasal discharge associated with dysphagia lasting for ninety days. The animal was submitted to endoscopy, showing a moderate amount of purulent secretion in both guttural pouches. With no improvement on the clinical treatment, we opted for surgical treatment by endoscopy through Salpingopharyngeus fistula made with the aid of a device containing an electrical scalpel developed to perform this technique. It consisted of making an incision in the pharyngeal recess in order to access the guttural pouches and subsequently drain the purulent content. The patient was discharged at the same day and returned to work 30 days after the procedure. Surgical treatment for cases of guttural pouch empyema is indicated when the clinical resolution has not been effective, and the minimally invasive technique is indicated due to the reduction of risks and the easiness of postoperative management. Until this moment, there are no reports of the salpingopharyngeal fistula technique through video surgery for the treatment of guttural pouch empyema, which has proved to be efficient for the treatment of the disease.

O objetivo deste trabalho é relatar a técnica de fístula salpingofaríngea por videocirurgia através de orifício natural (NOTES) para tratamento de empiema bilateral. Uma égua foi atendida no Setor de Grandes Animais da UFPR, com histórico de secreção nasal purulenta bilateral associado a disfagia há noventa dias. O animal foi submetido à endoscopia, evidenciando moderada quantidade de secreção purulenta em ambas as bolsas guturais. Sem apresentar melhora com o tratamento clínico, optou-se pelo tratamento cirúrgico por endoscopia através da realização de uma fístula salpingofaríngea feita com o auxílio de um dispositivo contendo eletrobisturi, desenvolvido para a realização desta técnica; que consistiu na realização de uma incisão no recesso faríngeo, para o acesso das bolsas guturais e posterior drenagem do conteúdo purulento. O paciente recebeu alta médica no mesmo dia e retornou ao trabalho 30 dias após o procedimento. O tratamento cirúrgico para os casos de empiema de bolsa gutural é indicado quando a resolução clínica não foi efetiva, sendo a técnica minimamente invasiva indicada devido à redução de riscos e à facilidade do manejo pós-operatório. Até o momento, não há relatos da técnica de fístula salpingofaríngea através de videocirurgia para o tratamento de empiema de bolsa gutural, a qual mostrou-se eficiente para o tratamento da enfermidade.

Histeropexia com aplicação de "toggles" para tratamento de piometra em mini horse / Pyometra treatment by histeropexy with toggles aplication in mini horse

Background: Brazil is an important horse breeder that creates about three million jobs and movements about R$16,15 billions per year. Although, it is important to the horse breeding industry success that the animals reproductive performance be kept. The mare pregnancy loss causes abundant forfeitures to horse breeders, furthermore, the chronic pyometra is one of that causes. The chronic pyometra is an uncommon mare condition, clinical treatments are often ineffective, under those circumstances the hysterectomy, ovariohysterectomy and uteropexy are recommended. This report proposes to describe the chronic pyometra surgical treatments with the uteropexy technique in mini horses that do not respond to the clinical treatment. Case: A 14-year-old mini breed horse mare weighing 117 kg was sent to Veterinarian Hospital (HV) of the Paraná Federal University (UFPR), presenting dystocia background and intrauterine purulent secretion. The clinical treatment had been conducted, but not well succeeded. An hysteroscopy was conducted with a cervix rupture monitoring, uterine mucosa edematiated and crispy, presenting liquid and a high amount of purulent secretion in the uterus horn and body. The biopsy identified uteropexy. The post-surgical complications were minimums and 30 days after the procedure the laparoscopy was repeated with uterine healing monitoring, without adherences and the uterus were at horizontal position. The hysteroscopy was conducted where a small amount of purulent secretion was perceived. Ten days after the second laparoscopy the patient was discharged. Two years after the procedure, the animal responsible informed that there was not a relapse. Discussion: the mare pyometra occurrence is uncommon and emerges by nature protection false mechanisms. Any change or flaw in one of these protection mechanics barriers, may result in a reproductive change due to uterine infection, resulting in reduction of mare reproductive capacity. Probably this reports patients developed pyometra due to the cervix lesion it's presented made easier the uterus external microorganisms entrance, that predisposes an chronic uterine infection. As many authors report, the chronic pyometra clinical treatment is not always successful, also observed in the case reported, indicating then surgical treatment. There are many pyometra surgical treatments indications as: Wedge resection technique in case of cervix adherence, uteropexy technique, ovary-hysterectomy technique or hysterectomy. The ovary-hysterectomy and the hysterectomy was not conducted for being considered highly invasive. This case choice procedure was the uteropexy, which corresponds to fixing the broad ligament of the uterus to the abdominal wall, repositioning it horizontally, to obtain a better drainage and motility, since this is your anatomic position. In the report, the surgical technique was conducted satisfactorily, certifying the uterine elevation by laparoscopy in the postoperative and also by the responsible report, that the animal does not relapse in two years. The postoperative complications were not alarming, considering that it ceased 24h after the procedure. The conclusions present in this treatment show that the hysteropexy conducted by videosurgery with toggles application developed the necessary uterine elevation to the liquid drainage, that allows the mare to execute the uterine cleaning by the physiological form.(AU)

Hernioplastia com aplicação de tela por laparoscopia em equino com hérnia incisional / Hernioplasty with laparoscopy mesh application in equine with incisional hernia

Background: Incisional hernia in the midline can be a consequence of abdominal surgeries, which incidence is around5.7-18%. Surgical indication occurs in cases of large hernias, and the most common techniques used involve the closingof the musculature in a primary way, with sutures, and the implantation of a mesh on the abdominal wall. Laparoscopichernioplasty emerged as a less invasive option, showing superiority when compared with open surgical techniques in human medicine, however there are few reports describing this technique in equines. So, the aim of this paper is to report acase of hernioplasty, using laparoscopic mesh, in a horse with midline incisional hernia.Case: A 13-year-old castrated male Brasileiro de Hipismo horse, weighing 415 kg, practitioner of classic equestrian, presented an incisional hernia after 14 days from an exploratory laparotomy surgery realized to treat colic syndrome. After 6months, the patient was referred to a Veterinary Medicine Teaching Hospital for the correction of the defect in the abdominal wall. During palpation, the animal did not present local pain or other sign of inflammation, and the hernia measuredapproximately 20 cm in diameter. The animal was submitted to general anesthesia and placed in dorsal decubitus for thehernioplasty surgical procedure. An incision was made in cranial region of the midline, close to the xiphoid to introduce asingle port; the abdomen was inflated with CO2 gas (12 mmHg) and the operating table was tilted in order to displace theorgans cranially, facilitating the laparoscopic procedure. The abdomen was inspected and the presence of a single adherence could be observed, which was disrupted with endoscopic forceps. The mesh was introduced through the single port...

Megaesôfago em muar / Megaesophagus in mule

Background: Megaesophagus is a chronic dilation of the esophagus rarely found in horses. It’s a non-specific disease that is associated with several causes, and esophageal hypomotility is the dysfunction that most commonly results in organ dilation. In the literature, there are few reports of megaesophagus in horses and, to date, no cases in mule have been reported. The objective of this work is to describe a case of a donkey with thoracic megaesophagus. Case: A 16 year-old donkey, castrated male, mixed breed weighing 195 kg, was referred for clinical care with a history of 5 days of anorexia. On physical examination, apathy, cachexia, 8% dehydration, moderate enophthalmos, ptialism, bilateral nasal discharge, dry and bristling hair were observed. Due to the poor general condition, a nasogastric tube was chosen to perform enteral nutrition, however, it was not possible to progress the tube to the stomach. In order to confirm the suspicion of a possible esophageal obstruction, gastroscopy was performed, where it was possible to observe an esophageal dilation filled with bulky food located in the thoracic portion of the esophagus. In an attempt to stimulate esophageal motility, in order to promote the progression of the material present in the region of dilation, intramuscular metoclopramide was administered (two applications every 6 h), however the treatment had no effect. Due to the unfavorable prognosis and financial limitations of the owner, euthanasia was performed, which was followed by autopsy and histopathological examination. At necropsy, a marked dilation of the esophagus was observed in the thoracic portion, which was filled with approximately 500 grams of bulky food (grass). In the mucosa of this area...
