A two and a half year old Chihuahua intact male dog weighing 1.7 kg was referred to our Animal Medical Centre presenting with ataxia, seizure, nystagmus, tremor, and tilt. Additionally, it was not able to stand and sit. Physical examination, palpation, neurology examination, complete blood count (CBC), serum chemistry test, radiographs (X-ray), ultrasonography (US), and magnetic resonance imaging (MRI) were all performed. Open fontanelle, domeshaped calvarium, a thinning of bone structure, and asymmetrically enlarged lateral ventricles on the right were found on diagnostic imaging. Accordingly, the dog was diagnosed with hydrocephalus. A VP shunt placement was performed as surgical treatment. The ventricular catheter was placed into the right lateral ventricle through the fontanelle insertion site and the distal catheter was placed in the abdomen using the percutaneous technique. After surgery, anorexia, seizure, tremor, and nystagmus disappeared. Also, the dog could stand and walk without support; however, gait was slow and not completely normal and the tilt remained.
A two-years-old, intact female, Shih-Tzu dog weighing 5 kg was presented to the Chonbuk Animal Medical Centre, College of Veterinary Medicine, Chonbuk National University, with the history of bone ingestion before two days. The survey radiographs of the thorax revealed a bone at the caudal thoracic oesophagus. An oesophagram was performed which did not reveal any oesophageal leakage or perforation. The left caudolateral thoracotomy was performed and the caudal oesophagus was found partially necrosed, friable and inflamed. The necrosed, friable part was removed and the oesophageal defect was reconstructed using a full-thickness muscle flap collected from the diaphragm. A part of the omentum was mobilized from the abdomen and sutured over the reconstructed site of the oesophagus to aid healing. Oesophagoscopy after nine days postoperatively showed a good adhesion of the diaphragm flap. The patient showed normal activity after 12 days and no complications were observed during a one-year follow up period. The pedicle flap collected from the left hemidiaphragm in addition to the omentum flap can be successfully used to reconstruct the circumferential oesophageal defect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
