RESUMO

Intra-abdominal or intrascrotal testicular torsion in dogs occurs due to spermatic cord rotation. Dogs with testicular torsion commonly present severe pain and require surgical intervention. Torsion of intra-abdominal retained testicles in cryptorchid adult dogs is often associated with the presence of testicular neoplasia. Herein, we reported the case of a 5-year-old male poodle with uncommon intra-abdominal testicular torsion (ITT) of a non-neoplastic testicle. The dog was referred to the veterinary hospital with acute abdominal pain in the hypogastric region. An intra-abdominal gonad and alterations compatible with testicular torsion were visualized during ultrasound examination. Orchiectomy and histopathological analysis of the testes confirmed the diagnosis of ITT in the absence of neoplasia. The patient recovered uneventfully from the situation. This report showed that ITT can occur in adult dogs in the absence of testicular neoplasia and reinforce the message that it should be included as a differential diagnosis in cases of acute abdominal pain in cryptorchid dogs. Furthermore, the ultrasound examination in this case of pain in the hypogastric region was decisive for the diagnosis of ITT.


A torção testicular intra-abdominal ou intra-escrotal em cães ocorre devido à rotação do cordão espermático. Os cães com torção testicular apresentam comumente dor intensa e necessitam de intervenção cirúrgica. Em cães adultos, a torção de testículos retidos no abdômen está geralmente associada à presença de neoplasia testicular. Este relato descreve um caso incomum de cão macho, de cinco anos de idade, da raça Poodle, encaminhado ao Hospital Veterinário com dor abdominal aguda na região hipogástrica. Durante o exame ecográfico, foi possível evidenciar um testículo e alterações compatíveis com torção testicular. A orquiectomia intra-abdominal e posterior análise histopatológica confirmaram a ITT sem neoplasia associada. O paciente apresentou evolução clínica satisfatória. Este relato mostra que a ITT na ausência de neoplasia pode ocorrer em cães adultos, reforçando a mensagem de que deve ser considerada como um diferencial diagnóstico em casos de dor abdominal aguda. Além disso, o exame ultrassonográfico realizado neste caso de dor na região hipogástrica foi decisivo para o diagnóstico de ITT.

RESUMO

Introduction. Gossypiboma is a rare surgical complication in small animals. The authors reported the laparoscopic diagnosis and treatment of an abdominal gossypiboma and chronic draining fistula postopen ovariohysterectomy (OVH) unresponsive to medical treatment in a bitch. Case Presentation. The patient had undergone OVH and exploratory laparotomy in other veterinary practice 3 years previously. The animal, presenting a chronic fistula, was then referred to UFSM Veterinary Hospital. Ultrasonographic examination revealed a structure compatible with a granuloma. For the laparoscopic procedure, a 3-port (two at 11 mm; one at 6 mm) access was used. Adhesiolysis and mass removal were performed by blunt dissection and bipolar electrocoagulation. The fistula was treated by mobilising the omentum through it. There were no intra- or postoperative complications. The chronic wound showed first intention healing. The mass was composed of fibrous tissues surrounding one surgical gauze. Discussion and Conclusion. The removal of a retained surgical gauze in the abdomen by laparoscopy has already been described in medicine. However, a laparoscopic approach for treating a fistulous draining tract due to a gossypiboma has not been previously reported in dogs. Laparoscopic exploration of the fistula allowed the use of a pedicled omental flap through infected sites to control chronic infection. Laparoscopic surgery can be used to identify and treat abdominal gossypiboma in dogs, including those with chronic abdominal sinus.

RESUMO

BACKGROUND: Intraoperative fluids are still poorly studied in veterinary medicine. In humans the dosage is associated with significant differences in postoperative outcomes. OBJECTIVES: The aim of this study is to verify the influence of three different fluid therapy rates in dogs undergoing video-assisted ovariohysterectomy. METHODS: Twenty-four female dogs were distributed into three groups: G5, G10, and G20. Each group was given 5, 10, and 20 mL·kg-1·h-1 of Lactate Ringer, respectively. This study evaluated the following parameters: central venous pressure, arterial blood pressure, heart rate, respiratory rate, temperature, acid-base balance, and serum lactate levels. Additionally, this study evaluated the following urinary variables: urea, creatinine, protein to creatinine ratio, urine output, and urine specific gravity. The dogs were evaluated up to 26 h after the procedure. RESULTS: All animals presented respiratory acidosis during the intraoperative period. The G5 group evidenced intraoperative oliguria (0.80 ± 0.38 mL·kg-1·h-1), differing from the G20 group (2.17 ± 0.52 mL·kg-1·h-1) (p = 0.001). Serum lactate was different between groups during extubation (p = 0.036), with higher values being recorded in the G5 group (2.19 ± 1.65 mmol/L). Animals from the G20 group presented more severe hypothermia at the end of the procedure (35.93 ± 0.61°C) (p = 0.032). Only the members of the G20 group presented mean potassium values below the reference for the species. Anion gap values were lower in the G20 group when compared to the G5 and G10 groups (p = 0.017). CONCLUSIONS: The use of lactated Ringer's solution at the rate of 10 mL·kg-1·h-1 seems to be beneficial in the elective laparoscopic procedures over the 5 or 20 mL·kg-1·h-1 rates of infusion.

RESUMO

Background: Trauma is the main cause of spinal fractures and dislocations in humans and large animals. Clinical signspresent with acute onset and vary according to the location and severity of the spinal cord injury. The treatment of fractures in large animals depends on economic value, cost of procedures, prognosis, location and type of fracture. However,although spinal fractures in large animals are not uncommon, the literature about their clinical aspects and treatment isscanty. Therefore, the purpose of this report is to describe a surgical stabilization of atlantoaxial subluxation, fracture ofthe third cervical vertebra and C2-C3 subluxation.Case: An approximately 2-year-old Île-de-France sheep, weighing 101 kg, with a history of cervical trauma and nonambulatory tetraparesis was treated at the Veterinary Hospital of the Institution (UNIPAMPA). During physical examination, the animal presented good general physical condition and heart rate, respiratory rate and temperature was accordingto physiological parameters for the species. The animal remained in lateral decubitus, with minimal head and limb movements, and exhibited deep pain sensitivity. Clinical treatment with dexamethasone, limb physiotherapy and change inlateral decubitus position were employed, but failed to improve the animals condition. After five days of unresponsive toclinical treatment, the patient was referred to the neurology department, where it underwent neurological examination andradiographic examination of the cervical region was performed under general anesthesia. The radiographic examinationrevealed atlantoaxial subluxation, by displacement of the odontoid process into the vertebral canal, fracture of the thirdcervical vertebra and C2-C3 vertebral subluxation. The surgical planning aimed cervical vertebral instability repair usingatlantoaxial arthrodesis associated the stabilization of C1-C2 and C2-C3 vertebrae with Schanz pins and bone cement...(AU)

RESUMO

Background: Tracheal intubation is performed in an anesthetized patient in order to optimize oxygenation and to allow the administration of volatile anesthetics. Some patients have characteristics that make intubation a challenge. Therefore, an adequate pre-anesthetic evaluation enables the anesthesiologist to define the best management. There are reports of the impossibility of performing conventional intubation attributed to the lack of pre-anesthetic consultation in Medicine, which motivates and justifies the discussion of these aspects in Veterinary Medicine. Therefore, this study aims to report a case of difficult airway management in a feline with tonsillitis. Case: A 3-year-old male NDB cat weighing 3.5 kg was admitted to the Veterinary Hospital, Federal University of Pampa (UNIPAMPA) - Uruguaiana, for consultation. After physical examination, total tooth extraction and tonsillectomy was recommended. On the day of the procedure, a physical evaluation of the patient was performed, and he was classified as ASA II. Zolazepam and tiletamine [Zoletil® - 5 mg/kg, i.m] associated with morphine [Dimorf® - 0.3 mg/kg, i.m] was given as premedication. Given the difficulty of intubation in a previous procedure reported by the tutor, a thoughtful conduct was planned for the intubation of the patient, considering the possibility of tracheostomy. The patient was pre-oxygenated, and subsequently, propofol [Propovan® - 4 mg/kg, i.v] was administered to promote anesthetic induction. The first attempt at intubation was done by laryngoscopy, but despite the use of a 6 cm blade, it was too large in relation to the hyperplastic tissue; then swabs and a flashlight were subsequently used. With the help of 2 people, the experienced anesthesiologist was able to position the endotracheal tube correctly approximately 25 min after the first attempt, requiring supplemental doses of propofol [Propovan® to the effect, i.v] and oxygenation between the attempts. Anesthetic maintenance was achieved with isoflurane [Isoforine® vaporized in 100% oxygen] in a system without gas rebreathing. Locoregional block of the maxillary nerve and inferior branch of the mandibular nerve was performed with lidocaine 2% [0.1 mL/kg]. During the transoperative, the vital parameters remained stable and there was no need for analgesic rescue. After the end of the procedure and extubation, the patient received oxygen therapy via facemask until he regained consciousness and had no complications. Discussion: The mortality of dogs and cats related to anesthetic procedures is substantially higher when compared to humans. Studies have shown that most anesthetic-related complications in humans are predictable. The lack of adequate pre-anesthetic evaluation or anesthetic consultation are factors that can cause losses in the transoperative period. Therefore, sharing information that can mitigate these situations is critical. The scarcity of reports on pre-anesthetic evaluation in veterinary medicine allows the identification of a gap on the role of the anesthesiologist in this important stage of anesthesia, and how it is performed in the hospital routine or in veterinary clinics. The success in managing the difficult airway in the case reported here can be attributed to the procedures adopted in all stages of the procedure, especially the planning based on information obtained during the pre-anesthetic period. It is worth mentioning that the owner was a veterinarian and we believe this also contributed to the outcome, since he informed the anesthesiologist about the difficulties encountered during the previous procedure. This case motivated the implementation of a pre-anesthetic consultation service in the hospital in question. In addition to the physical examination, a complete anamnesis carried out with the owner may reveal relevant details for determining the most appropriate and safe anesthetic conduct for the patient.

RESUMO

This case report presents a celioscopy procedure followed by partial salpingectomy (PS) in a pregnant bitch referred to elective video assisted ovariohysterectomy. Through celioscopy it was visualized the embryonic vesicles and PS was performed after conversion to minioceliotomy. The puppies were born by eutocic delivery without clinical alterations. The case suggested that short and regular pneumoperitoneum is not deleterious to dog fetus and video surgery could be used in pregnant bitches. PS allows the fetus development and promotes bitch neutering.(AU)

RESUMO

INTRODUCTION: Nanoparticle solutions have been studied to improve antimicrobial effect. The aim of this study was to develop, characterize, and evaluate the in vitro and in vivo antiseptic efficacy of 0.25% aqueous-based chlorhexidine nanoemulsion (NM-Cl 0.25% w/v). METHODS: The NM-Cl 0.25% w/v (2.5mg/mL) and free chlorhexidine nanoemulsion (FCN; same composition of NM-Cl without the molecule of chlorhexidine) were synthetized by the spontaneous emulsification method. Characterization analyses of physical and chemical properties were performed. The NM-Cl 0.25% w/v was compared with chlorhexidine 0.5% alcohol base (CS-Cl 0.5%) in vitro studies (microdilution study and kill curve study), and in vivo study (antisepsis of rats dorsum). Kruskal-Wallis test was used between groups and inside the same group, at different sample times and the Mann-Whitney test was performed when difference was detected. RESULTS: The NM-Cl 0.25% w/v presented adequate physicochemical characteristics for a nanoemulsion, revealing a more basic pH than FCN and difference between zeta potential of NM-Cl 0.25% w/v and FCN. The NM-Cl 0.25% w/v and CS-Cl 0.5% solutions were more effective on Gram-positive than on Gram-negative bacteria (p≤0.05). NM-Cl 0.25% w/v presented upper antiseptic effect in the microdilution study and residual antiseptic effect was maintained for a longer time when compared to CS-Cl 0.5% (kill curve study). The four-fold (minimal inhibitory concentration) of NM-Cl 0.25% were the formulations with most durable effect within those tested, presenting residual effect until T6 for both bacteria. In the in vivo study, both formulations (NM-Cl 0.25% w/v and CS-Cl 0.5%) had a reduction of the microorganisms in the skin of the rats (p<0.0001) not revealing any difference between the formulations at different times, showing the antiseptic effect of NM-Cl (p≤0.05). CONCLUSION: Both in vitro and in vivo experiments demonstrated that NM-Cl showed promising future as an antiseptic for cutaneous microbiota.

RESUMO

For ethical and organic reasons, surgical and analgesic techniques that minimize and adequately control pain should be studied. Ovariohysterectomy is the most common surgical technique in veterinary medicine and is performed in female dogs for elective or therapeutic purposes. Both conventional and minimally invasive surgical techniques are used in veterinary medicine; however, the minimally invasive laparoscopic technique is considered superior to the conventional technique because it is associated with a less painful and faster post-operative recovery. However, for various reasons, the laparoscopic technique is not yet widely used in veterinary medicine, and the conventional ovariohysterectomy is still the most common. The aim of this study, therefore, was to validate the efficacy of the combination of dipyrone, scopolamine, and meloxicam after conventional or two-port laparoscopic-assisted ovariohysterectomies in female dogs. Additionally, this study sought to assess recovery after the two surgical modalities while receiving the same analgesic protocol. Fourteen healthy adult female dogs were spayed and then evaluated using the Visual Analogue Scale, the Melbourne Scale, and the short form of the Glasgow Composite Measure Pain Scale for 72 hours after surgery. The analgesic protocol was efficient for pain control after both techniques, with minimal differences between the groups.(AU)

A ovário-histerectomia é a técnica cirúrgica mais realizada em medicina veterinária, seja aplicada com fins eletivos ou terapêuticos. As técnicas cirúrgicas convencionais e minimamente invasivas são utilizadas em medicina veterinária, e as laparoscópicas são consideradas superiores, pois promovem menor dor e mais rápida recuperação pós-operatória. Embora esta modalidade cirúrgica seja considerada superior, por diferentes razões ainda não é tão difundida na medicina veterinária, sendo a técnica convencional de ovário-histerectomia a mais utilizada em cadelas. Por estas razões, o objetivo deste estudo foi validar a eficácia do protocolo dipirona, escopolamina e meloxicam em cadelas submetidas a ovário-histerectomia convencional ou videoassistida por dois portais, assim como avaliar a recuperação dos animais submetidos a duas modalidades cirúrgicas junto ao referido protocolo analgésico. Assim, 14 cadelas adultas saudáveis foram submetidas a ovário-histerectomia e avaliadas por meio da Escala Visual Analógica, Escala de Melbourne e Forma reduzida da Escala Composta de Glasgow até 72 horas após a realização do procedimento cirúrgico. O protocolo analgésico foi eficiente para controle da dor nos animais submetidos a ambas as técnicas cirúrgicas, e mínimas diferenças foram observadas entre os grupos.(AU)

RESUMO

Background: Perineal hernia is characterized by the displacement of abdominal organs to the perineal region after ruptureor weakening of the pelvic diaphragm muscles. This condition is common among middle-aged and elderly unneuteredmale dogs. Considering the severity of the condition and its rarity among bitches, this paper reports on a case of perinealhernia caused by hydrometra in a 12-year-old pinscher bitch.Case: The patient was a 12-year-old Pinscher bitch, weighing 3 kg, suffering from anuria and constipation in the 36 hprior to treatment, without reported trauma. She was unspayed, and her last estrus had occurred approximately thirty dayspreviously. The physical examination revealed an increase in volume in the right perineal region, increased volume in theleft inguinal region, increased body temperature (39.8ºC), pale mucous membranes, tachycardia, tachypnea, abdominalpain and increased popliteal lymph nodes. The diagnosis was determined based on her medical history, clinical signs andan ultrasound scan, which revealed dilated uterine horns displaced unilaterally in the left inguinal region, with evidence ofhydrometra, full urinary bladder inside the hernia sac in the right dorsolateral perineal region and right kidney pyelectasis.After evaluating the animals physical condition, surgery was recommended, involving ovariohysterectomy associatedwith inguinal and perineal herniorrhaphy.Discussion: Perineal hernia, a common condition in male dogs, is characterized by the displacement of organs towardsthe perineal region. However, in this case, this condition occurred in female dog. Unlike males, the main causes of perineal hernia in females are trauma, chronic coughing related to heart disease, bronchitis, and tracheal collapse. Increasedintra-abdominal pressure associated with a weak pelvic diaphragm predisposes for herniation of abdominal contents,such as occurred through hydrometra. In this case...(AU)

RESUMO

Background: Ovariohysterectomy (OVH) is one of the most applied techniques in Veterinary Medicine. Despite some analgesic protocols being used after this procedure in order to control post operatory pain, there is a lack of knowledge of the efficacy after conventional and two port laparoscopic-assisted techniques in dog female. Although the combined formulation of metamizol and scopolamine is used, there is no knowledge about the efficacy and collateral effects in a 6 h regimen after OVH. The aim of this research was to evaluate the efficacy of metamizol and scopolamine to analgesia after two techniques of OVH in dog female. Materials, Methods & Results: Fifteen adults and healthy dog female were submitted to OVH, being eight to the conventional procedure and seven to video assisted technic with two ports. The patients received a combination of metamizol and scopolamine, 6-6 h during 48 h and were evaluated before surgery, 60 min after extubation and on 1 h interval during the f irst 8 h, and at 12, 18, 24, 36, 48 and 72 h after surgery. For this, the University of Melbourne Pain Scale (UMPS) and the short-form of the Glasgow Composite Measure Pain Scale (CMPS-SF) were applied by three evaluators blinded to surgical technic. Glucoses measurement was realized at 1, 6, 12, 24, 48 and 72 h after surgery. Analgesic rescue was not necessary for any animal. Punctuation of UMPS in GC decreases at 8 h and at 5 h, and to GV at 12 and 24 h. Difference between groups happened at 3 h with larger average to GV; at 48 h the punctuation in GC was lager. Considering CMPS-SF to CG, higher average was observed at 1 h and decreased at 2, 3, 8 and 18. At GV highest average points was verified at 1, 2 and 3 h and decreased at 5, 8 and 18 h. Correlation was strong and positive between each two evaluators. Animals of both groups had increased average...

RESUMO

Background: Perineal hernia is characterized by the displacement of abdominal organs to the perineal region after ruptureor weakening of the pelvic diaphragm muscles. This condition is common among middle-aged and elderly unneuteredmale dogs. Considering the severity of the condition and its rarity among bitches, this paper reports on a case of perinealhernia caused by hydrometra in a 12-year-old pinscher bitch.Case: The patient was a 12-year-old Pinscher bitch, weighing 3 kg, suffering from anuria and constipation in the 36 hprior to treatment, without reported trauma. She was unspayed, and her last estrus had occurred approximately thirty dayspreviously. The physical examination revealed an increase in volume in the right perineal region, increased volume in theleft inguinal region, increased body temperature (39.8ºC), pale mucous membranes, tachycardia, tachypnea, abdominalpain and increased popliteal lymph nodes. The diagnosis was determined based on her medical history, clinical signs andan ultrasound scan, which revealed dilated uterine horns displaced unilaterally in the left inguinal region, with evidence ofhydrometra, full urinary bladder inside the hernia sac in the right dorsolateral perineal region and right kidney pyelectasis.After evaluating the animal’s physical condition, surgery was recommended, involving ovariohysterectomy associatedwith inguinal and perineal herniorrhaphy.Discussion: Perineal hernia, a common condition in male dogs, is characterized by the displacement of organs towardsthe perineal region. However, in this case, this condition occurred in female dog. Unlike males, the main causes of perineal hernia in females are trauma, chronic coughing related to heart disease, bronchitis, and tracheal collapse. Increasedintra-abdominal pressure associated with a weak pelvic diaphragm predisposes for herniation of abdominal contents,such as occurred through hydrometra. In this case...

RESUMO

Mesothelioma is a very aggressive malignant tumor with low survival rates that is often diagnosed belatedly. Pericardial effusion is a common consequence in cases of mesothelioma, with pericardiocentesis and pericardiectomy indicated; therefor thoracocentesis is necessary to drain the contents no longer retained in the pericardium. The present report describes a mesothelioma-carrying dog with a history of cardiac tamponade that underwent thoracoscopic pericardiectomy and, later, thoracoscopic implantation of a fully implantable catheter to function as a thoracic drain. In the consulted literature, there is no use of a fully implantable catheter for this purpose. The authors consider that there was an improvement in the quality of life.

RESUMO

Background: The lymphatic system plays an important role in the local control of neoplasms as well as in the transportation of tumor cells, which represents the most common pathway of metastasis. From the tumorigenesis, there is a remarkable enlargement of the tumor drainage network towards the regional and target lymph nodes. Since the mammary lymphatic system of animals with neoplasms as well as the demarcation of the pelvic and abdominal caudal chain are poorly studied, the aim of the present study is to report a case of iliac lymphadenectomy after intrauterine lymphatic dyeing in a dog with breast neoplasm, which allowed the identification of metastasis in the medial iliac lymph node.Case: A 7-year-old, 13.4 kg, non neutered, mixed breed, female dog was diagnosed with ulcerative neoplasm in the left caudal abdominal breast, which presented evolution of approximately 90 days, presenting ulceration for 10 days, according to the tutor. After a clinical evaluation, thoracic radiography and abdominal ultrasonography were requested, which did not present metastasis suggestive images. Therefore, left unilateral total mastectomy was indicated. Retro-umbilical celiotomy was performed for the administration of 0.5 mL of 1% intrauterine methylene blue (body of the uterus), which allowed lymphatic mapping and medial iliac lymphadenectomy. Subsequently, ovariohysterectomy was performed and after celiorrhaphy, axillary lymphadenectomy was performed, followed by left unilateral mastectomy and concomitant removal of the superficial inguinal lymph node. The patient had a prompt recovery and was discharged from hospital in six hours postoperatively. The excised material was referred for histopathological examination, which revealed the presence of metastasis of simple tubulopapillary carcinoma of the mammary gland in the left medial and superficial inguinal lymph nodes, while the axillary lymph node had no metastases.[...](AU)

RESUMO

Background: Dioctophyme renale, also known as “giant kidney worm”, is a cosmopolitan parasite, which usually affects domestic and wildlife canids in wetlands. Nephrotomy and nephrectomy are the only treatment options. Laparoscopic nephrectomy for dioctophymosis was first performed in veterinary patients in the late 90’s. Canine pyometra is one of the most frequent surgical disorder in the small animal setting. The purpose of this study was to report a case of successful one-stage laparoscopic approach for nephrectomy and ovariohysterectomy in a bitch.Case: A female stray dog, rescued from a riverside community, was presenting hematuria. Abdominal echography revealed presence of Dioctophyme renale worms within the right renal parenchyma. Moreover, the uterus was moderately filled by anechoic content. The patient was clinically stable and undergone laparoscopy. A 10-mm trocar was established at the middle third of the right flank, followed by 12-mmHg CO2 insufflation. The telescope was inserted and a giant worm was seen free within the abdominal cavity. A second 10-mm port was inserted cranial and dorsally to the first one. The parasite was retrieved using a laparoscopic Kelly forceps. A third 5-mm trocar was inserted in a classic laparoscopic triangulation port positioning. Renal artery and vein were individually triple ligated using titanium clips and then transected. The right ovarian pedicle was sequentially coagulated and transected using laparoscopic bipolar forceps. The right kidney was then dissected and detached from the abdominal wall, followed by cauterization and transection of the left ovarian pedicle. The uterus was exposed out of the abdominal cavity through the 5-mm port access. Uterine body and vessels were double ligated using polyglactin 910, with transfixating ligatures, and then transected. The opening of the retrieval bag was exposed through the cranial port site incision.[...]
