Three dogs with suspected patent ductus arteriosus were referred to Veterinary Medical Teaching Hospital of College of Veterinary Medicine, Konkuk University because of cough, shortness of breath, exercise intolerance, and syncope, Continuous murmur and thrill were detected in physical examination. Left ventricular enlargement, cardiomegaly, bulged main pulmonary artey were found in radiography. Tall R wave, wide P wave, atrial fibrillation, and turbulent flow were observed in electrocardiogram and echocardiogram. Thoracotomy was performed at left fourth intercostal space under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. The median (mean ${\pm}$ SD) diameter of patents was $8.0{\pm}2.0mm$. The median operation time was $36{\pm}6.6min$. On examination right after surgery, continuous murmur, thrill, atrial fibrillation, and turbulent flow were disappeared. On 30 days after surgery, clinical signs, left ventricular enlargement, and, bulged main pulmonary artery were disappeared. VHS 12.5 and 13.5, R wave 3.3 and 3.0 mV, and P wave 0.05 and 0.05 sec were decreased to 10.0 and 10.5, 1.8 and 2.0 mV, and 0.04 and 0.04 sec respectively in case 1 and 2. Ratio of aorta and main pulmonary artery in diameter was changed 1 : 1.3 and 1 : 1.6 into 1 : 1.1 and 1 : 1 respectively in case 1 and 2. Mild tear developed during dissection in case 3 and hemorrhage was controlled by vascular Devakey forceps. However, the dog died. On 12 months after surgery, patients (case 1 and case 2) have not showed abnormal signs.

윤헌영,Derek B. Fox,정순욱 한국임상수의학회 2008 한국임상수의학회지 Vol.25 No.3

A 1.4 kg adult great horned owl was presented to the University of Missouri-Columbia Veterinary Teaching Hospital after being found by the side of the highway. Physical examination revealed soft tissue injuries to the left wing and leg, and good body condition (body score 4/5). The radiographs revealed comminuted fracture of the diaphysis of the left tibiotarsus (severe) and ulna (mild). Closed reduction of the fracture was performed to the left tibiotarsus and ulna. System combining an intramedually (IM) Kirschner pin, IM Kirschner pin for external skeletal fixation, and polymethylmethacrylate was used for fracture repair. At 13 weeks, radiographs revealed that bridging callus was well formed over cortices of the fracture area. No physical, behavioral, or other assessable impairment was found during the rehabilitation period.

A 4.65 kg 13-month-old male Pekingese dog was referred to veterinary teaching hospital of KonkukUniversity for evaluation of dysuria. On physical examination, severe distention of urinary bladder was found inabdominal palpation. Urinary catheter could not be guided into urinary bladder. On serum biochemistry, blood ureanitrogen (35.6 mg/dl) and creatinine (1.9 mg/dl) were increased. Obstruction part of proximal membranous urethra wasfounded on urethrogram. The length (13 m) of obstruction part was callipered by cystourethrogram and urethrogramwas performed with 5-0 polyglycolic acid. Omentum was placed around the urethral anastomosis. On first day aftersurgery, appetite was good. On day 5, complete blood count and serum biochemistry showed normal range but mildurinary incontinence was showed after removing catheter. On day 7, urinalysis showed normal condition. On day 14,no leakage of surgical site was observed in excretory urogram. On day 21, no more urinary incontinence and goodmicturition were found. On 1 year later, the patient showed healthy condition without recurrence.

윤헌영,변재영,박강효,민병수,김정현 대한면역학회 2017 Immune Network Vol.17 No.2

Two young dogs were referred to the Veterinary Medical Teaching Hospital of Konkuk University, one for examination of vaginal discharge and the other after being hit by a car. Dog 1 exhibited a high neutrophil count on Gramstained vaginal smears, marked leukocytosis on a complete blood count, and uterine enlargement on ultrasonography. In dog 2, a markedly enlarged right uterine horn containing echogenic debris was found incidentally on ultrasonography. A tentative diagnosis of pyometra was made in both cases and ovariohysterectomy was performed. Purulent material was collected from each uterine horn and submitted separately for aerobic and anaerobic bacterial culture; all culture results were negative. The white blood cell count revealed normal limits 2 days post operation in dog 1 and 4 days post operation in dog 2. Positive bacterial cultures are usually obtained from dogs with pyometra, and antibiotic selection is based on the results of culture and sensitivity testing in the event of failure of empiric antibiotic therapy. However, in the cases reported here, no bacterial growth was identified from the uterine samples despite the presence of purulent material. A short course of empiric antibiotic therapy was administered. This is the first known report describing sterile pyometra in dogs.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

윤헌영,노미영,정순욱 한국임상수의학회 2013 한국임상수의학회지 Vol.30 No.1

A 12-year-old male poodle weighing 2.0 kg presented for evaluation of right thoracic limb lameness. The owner reported that the dog showed recurrent bilateral shoulder joint luxation after a car accident for a year. Recently,the left shoulder joint appeared well maintained, but right shoulder joint luxation was exacerbated. On physical examination, the dog showed non-weight bearing lameness on the right thoracic limb. Craniocaudal radiographic views revealed medial displacement of the right humerus. Mediolateral radiographic views revealed overlap of the glenoid cavity and humeral head. Muscle atrophy of the right thoracic limb, reduced biceps brachii muscle tendon tone, a tear of the medial glenohumeral ligament, and a rupture of the subscapularis tendon were identified intraoperatively. Transposition of the biceps muscle tendon was performed. However, at 7 days, there was evidence of right shoulder reluxation on radiographs. The second surgery was performed with two 2 mm × 6 mm cortical bone anchors and a 4mm× 6 mm cancellous bone anchor placed in the cortical bone of the distal scapula and the cancellous bone of the proximal humerus respectively. Two scapular bone anchors were then connected with a humeral bone anchor using heavy nylon suture to minimize shoulder abduction range of motion. On radiographs right after surgery and 6 weeks after surgery, the affected limb revealed no evidence of medial shoulder luxation. At 6 months, no evidence of lameness was noted on the right thoracic limb.

Lung Lobe Torsion with Concurrent Intestinal Lymphangiectasia in a Maltese Dog

윤헌영,정순욱 한국임상수의학회 2011 한국임상수의학회지 Vol.28 No.2

A 4-year-old intact male, Maltese dog weighing 2.2 kg was presented for evaluation of tachypnea and hyperthermia. On initial evaluation, the dog was dyspneic, but alert and responsive. Muffled heart sound was noted with auscultation of the right hemithorax. The radiographic findings were consolidation of the right middle lung lobe,pleural effusion, and abdominal fluid accumulation. Thoracic computed tomography confirmed a contrast-enhancing mass within the right middle lung lobe. Surgical exploration of the thoracic cavity was performed using a right fifth intercostal thoracotomy. Examination of the right lung lobe revealed 360o torsion of the right middle lung lobe at the level of the hilus, in a clockwise direction. Lung lobectomy was performed using a thoracoabdominal stapling device with 2.5-mm vascular staples. Full-thickness intestinal biopsy by exploratory laparotomy was taken from the jejunum for histological assessment. Histopathologic examination of the full-thickness intestinal biopsy revealed distended lacteal located within the submucosa of the jejunum. Intestinal lymphangiectasia was resolved with prednisone and low fat diets. Subsequent communication with the owner revealed that the patient was in good health 6 months post-discharge.

윤헌영,이정하,신동욱,박희명,정순욱 한국임상수의학회 2014 한국임상수의학회지 Vol.31 No.5

Two dogs were presented with a history of anorexia, respiratory distress, or epistaxis. On physicalexamination, the dogs showed difficulty breathing and open-mouth breathing and large masses were found on the hardpalate and soft palate. Cardiac arrest happened in case 2 and the dog was stabilized with cardiopulmonary resuscitationand oxygen therapy. Computed tomography demonstrated that the mass occupied the oropharynx, intrapharyngealostium, and laryngopharynx including the hard palate and soft palate in case 1. Palliative surgery was decided to improveswallowing and breathing with owner’s consent in two dogs. Buccal mucosal flaps were performed for reconstructionof defects using rotational and single-pedicle advancement flaps and bilateral 90 degree transposition flaps in cases1 and 2, respectively. Histopathology results described the oral masses as amelanotic melanoma in two dogs. Theowners reported that there was normal swallowing and breathing at 7 days postoperatively in two dogs. In case 1,recurrent tumor was identified caudal to the hard palate 4 weeks after surgery. The owner did not allow further treatmentand the dog became lost to follow-up at 2 months postoperatively. In case 2, there was no clinical or radiographicevidence of a local recurrence or distant metastasis at 3 weeks after surgery. The owner informed that the dog diedsuddenly with no signs of anything particularly wrong at 7 weeks after surgery.

윤헌영,강명곤,정순욱 한국임상수의학회 2009 한국임상수의학회지 Vol.26 No.6

Five dogs presented to the Veterinary Medical Teaching Hospital of the Konkuk University and Hangang Animal Hospital with a history of foreign body ingestion. On physical examination, five dogs showed lethargy, anorexia, or vomiting. Plain radiographs revealed that radiopaque foreign bodies lodged in the heart base or caudal thoracic esophagus. Positive contrast esophagogram revealed that large foreign bodies severely expanded the esophagus and there was no evidence of leakage of the contrast agent from the esophagus into the thoracic cavity. Gastrotomy for retrieval of esophageal foreign bodies using long forceps technique was performed. Esophageal foreign bodies were successfully retrieved in all dogs. The follow-ups were completed 10 days to 2 years after surgery. The follow-up information was based on physical examination by veterinarians and telephone interview with owners. The owners reported that there was no evidence of complications related to surgery such as vomiting, regurgitation, dysphagia, gagging, hyper-salivation, or anorexia in all dogs.
