ThesisItem Restricted ASSESSMENT OF WOUND HEALING FOLLOWING COLLAGEN URETHRAL STENT PLACEMENT FOR URETHROTOMY IN DOGS(2021) NISHANTH C; TANUVAS; GOKULAKRISHNAN M; MOHAMED SHAFIUZAMA; KANNAN TAUrethral obstruction is an emergency clinical scenario in dogs which leads to post-renal azotemia due to obstruction of urine flow. The most common cause of urethral obstruction is urolithiasis which was diagnosed with ultrasonography and radiography in the present study. A total of 12 animals presented to Madras Veterinary College teaching hospital with the history of urinary obstruction were chosen for the study and were randomly divided into 2 groups of 6 animals each. Group I animals were treated with conventional urethrotomy procedure and group II animals were treated with urethrostomy with collagen urethral stent placement. The collagen material used was an acellular matrix of bovine origin. The acellular collagen matrix was tubularised into urethral stent and placed inside the urethra and the urethrotomy was closed and the surgical wound was evaluated post-operatively for 14 days. Haemato-biochemical parameters were assessed pre-operatively and post operatively on days 0, 3, 7 and 14 and found that the renal parameters were significantly different in both the groups I and II between the pre-operative and post-operative period indicating the change in renal function before and after relieving the urethral obstruction. Plain and contrast radiography were used to determine the urethral lumen diameter and urethral leakage post-operatively in both the groups I and II which revealed no urethral leakage or urethral stricture post-operatively in both the groups indicating that acellular collagen matrix prevented urethral leakage and stricture. Ultrasonography was used to assess the collagen stent absorption, collapse and migration post-operatively in group II animals. There was no collagen stent collapse or stent migration in any of the animals in group II. Ultrasound revealed a partial absorption of collagen stent on day 7 and a complete absorption at day 14 post-operatively. Short Form of Glassgow Composite Measure Pain Scale (CMPS-SF) was used to evaluate acute pain in this study on 3"*, 7^ and 14^ post-operative days. There was no significant difference in the pain scores between the groups indicating that the collagen stent does not elicit any extra pain than normal urethrotomy procedure.ThesisItem Restricted COMPUTED TOMOGRAPHY AND ULTRASONOGRAPHY FOR DIAGNOSIS OF OPHTHALMIC DISEASES IN DOGS(2022) NIRANJANA C; TANUVAS; MOHAMED SHAFIUZAMA; RAMANI C; PAZHANIVEL N; JEYARAJA KComputed Tomography (CT) and Ultrasonography (US) are useful, complementary cross-sectional imaging modalities of the eye and orbit. The aim of the present study was to assess the efficacy of computed tomography over ocular ultrasonography in diagnosing various ophthalmic lesions in dogs and to study the effectiveness of Hounsfield unit (HU) in accurate diagnosis of ophthalmic diseases in dog. The study was carried out on 43 dogs of different breeds (86 eyes with respect to ophthalmic lesions), aged 2 months to 11 years with retrobulbar tumours, eye ball lesions, extraocular and intraocular lesions, retinal detachment, optic disc lesions and amaurosis. All the dogs with ocular disorders were subjected to detailed ophthalmic examination and computed tomography was done under general anaesthesia. A 38 mm linear array transducer of 6-18 MHz was used for ultrasonography in this study. Computed tomographic scan was taken on sternal recumbency under general anaesthesia with collimation focused on the skull. The factors while taking CT were fixed at 120 kVP, 150 mA,112-115 mAs and slice thickness of 1 mm using 16-slice CT scanner were fixed.ThesisItem Restricted POLY AXIAL LOCKING PLATE SYSTEM (PAX) FOR THE MANAGEMENT OF LONG BONE FRACTURES IN DOGS(2022) SARAVANA KUMAR P; TANUVAS; ARUN PRASAD A; MOHAMED SHAFIUZAMA; SATHYAMOORTHY ORThe present study was designed with the objective of evaluating Polyaxial Locking Plate system (PAX) and the intra-operative intricacies involved during application of Polyaxial Locking Plating system for long bone fracture management in dogs. The study was conducted in Small Animal Orthopaedics Unit of Madras Veterinary College Teaching Hospital from March 2021 to December 2021. A study on incidence of long bone fractures, in 609 cases presented during the study period revealed that fractures were more common in radius and ulna followed by femur, tibia and fibula and humerus. Distal fractures occurred commonly in femur, radius and ulna and humerus whereas, proximal fractures were common in tibia and fibula. Transverse fractures occurred highest followed by oblique fractures in all long bones. Young puppies of 0-6 months age were more prone than adult dogs and males were affected more than females. Among different breeds incidence was highest in non-descript dogs followed by Labrador, Spitz, German Shepherd dogs and others.ThesisItem Restricted RADIOGRAPHIC AND COMPUTED TOMOGRAPHIC ASSESSMENT OF CHRONIC OTITIS EXTERNA AND ITS SURGICAL MANAGEMENT IN DOGS(2021) DIVYA V; TANUVAS; NAGARAJAN L; MOHAMED SHAFIUZAMA; KANNAN TATwelve cases of chronic otitis externa that presented to the Small Animal Out-patient unit of Madras Veterinary College Teaching Hospital were chosen for this study. They were randomly divided into two groups of six animals each. Lateral ear canal resection was performed in animals of group I, and vertical ear canal ablation was performed in animals of group II. Cytology, culture, and antibiotic sensitivity was done on day 0 and the 14th post-operative day. Radiography and computed tomography (CT) were done on day 0 and the 30th post-operative day. Dorso-ventral and lateral oblique orthogonal views of the skull were taken on radiography to assess the external ear canal and the tympanic bulla. CT was done with a 16-slice helical CT scanner with 1mm slice thickness and slice interval. Images were assessed in both the bone and soft tissue windows. Parameters measured were the length of the vertical canal, length of the horizontal canal, diameter at the external auditory meatus, diameter at the junction of the vertical and horizontal canal, diameter at the proximal end of the horizontal canal, presence of soft tissue opacity within the lumen of the horizontal canal, presence of mineralization and presence of narrowing of the external ear canal. Additionally, the maximum thickness of the vertical and horizontal canal was measured on CT.
