Transendoscopic Nd: YAG Laser Ablation of Vaginal Septa in a Bitch     

MICHAEL D. WHITACRE DVM  MS  Diplomate ACT    LLOYD P. TATE VMD  Diplomate ACVS    CHARLES T. ESTILL VMD  Diplomate ACT  STEVEN D. VAN CAMP DVM  Diplomate ACT 《Veterinary surgery : VS》1991,20(4):257-259

A vaginal septum was diagnosed in an English bulldog bitch during routine estrous cycle staging. The septum extended 16 cm from the vestibulo-vaginal junction to just caudal to the cervix. The septum was removed by two applications of an Nd:YAG laser via a flexible fiberoptic endoscope. Complete healing occurred over a 5-week period and was uneventful. The bitch was bred and subsequently delivered four puppies vaginally. Transendoscopic laser ablation provided a noninvasive approach to surgically remove a vaginal septum in the dog.  相似文献

RADIOGRAPHIC EVALUATION OF CAUDAL VENA CAVA SIZE IN DOGS     

Linda B.  Lehmukhl  DVM  MS  John D.  Bonagura  DVM  MS  David S.  Biller  DVM  MS  Wendie M.  Hartman 《Veterinary radiology & ultrasound》1997,38(2):94-100

Dilation of the caudal vena cava (CVC) on lateral thoracic radiographs is often interpreted as suggestive of right-sided congestive heart failure. To quantitate the clinical utility of evaluating CVC size as an indicator of right-sided heart disease, we compared the ratio of the diameter of the CVC as measured on a left lateral thoracic radiograph to the descending aorta (Ao), length of the thoracic vertebra above the tracheal bifurcation (VL), and width of the right fourth rib (R4) in 35 dogs with right heart disease and 35 control dogs. Each CVC ratio (CVC/Ao, CVC/VL, CVC/R4) was statistically larger in dogs with right heart disease. Response operating characteristic curves and likelihood ratios were used to determine ratios helpful in identifying dogs with right heart disease. A CVC/Ao > 1.50, CVC/VL > 1.30, or CVC/R4 > 3.50 are strongly suggestive of a right-sided heart abnormality in a patent.  相似文献

Use of toltrazuril in pullet breeding flocks raised on floors with anticoccidial-free feed     

H P Schmid  R Weber  C Schwarzer  H C Mundt  P Dorn 《DTW. Deutsche tier?rztliche Wochenschrift》1991,98(4):141-144

In 28 replacement pullet flocks with flock size of 4,000 to 25,000 birds Toltrazuril (experimental preparation, 2.5% solution, approx. 7 mg/kg body weight) was administered for a period of two days in the drinking water for metaphylactic purpose and therapeutic use, respectively. All flocks were reared without anticoccidial feed additives. Exposition to Eimeria spp. was recorded by examination of faecal samples and intestinal scrapings. Clinical flock control was achieved by vets at eight to ten day intervals. Toltrazuril was characterized by short application period, rapid mode of action, significant reduction of oocyst shedding, good compatibility and acceptance thus proving superior to conventional chemotherapy of coccidiosis. The results suggest that, even without administration of anticoccidial feed additives. Toltrazuril is an effective agent for therapeutic use in acute coccidiosis. Under insufficient management and rearing conditions repeated metaphylactic application has to be considered.  相似文献

THE USE OF GATED RADIONUCLIDE VENTRICULOGRAPHY AS A NONINVASIVE METHOD OF EVALUATING RIGHT VENTRICULAR FUNCTION IN DOGS WITH EXPERIMENTALLY INDUCED CONGESTIVE HEART FAILURE     

Kathy  Arrington  DVM  Janice M.  Bright  DVM  Gregory B.  Daniel  DVM  MS 《Veterinary radiology & ultrasound》2001,42(1):62-69

Gated radionuclide ventriculography was evaluated as a noninvasive method of quantifying right ventricular function in dogs with experimentally induced congestive heart failure. Gated radionuclide ventriculography measurements of right ventricular function (right ventricular ejection fraction, right ventricular average emptying rate, and right ventricular average filling rate) were related to standard hemodynamic and echocardiographic measurements. Congestive heart failure was induced by rapid ventricular pacing in eight normal dogs. Hemodynamic, echocardiographic, and gated radionuclide ventriculography measurements were obtained before and after development of biventricular failure. Congestive heart failure resulted in significant changes in all hemodynamic, echocardiographic, and gated radionuclide ventriculography measurements with the exception of systemic arterial pressure. Right ventricular ejection fraction was inversely related to pulmonary artery systolic, diastolic, and mean pressure, and right ventricular average emptying rate was inversely related to the pulmonary artery systolic, diastolic, and mean pressure. Right ventricular ejection fraction was inversely related to left ventricular filling pressure, (pulmonary capillary wedge pressure). Neither the echocardiographic measurements of right ventricular size (right ventricular internal diastolic dimension) nor the right ventricular end-diastolic pressure were related to right ventricular ejection fraction and right ventricular average emptying rate. However, echocardiographic measurements of right ventricular dimension were related to right ventricular filling pressure. The gated radionuclide ventriculography indexes of right ventricular function, right ventricular ejection fraction and right ventricular average emptying rate, are affected by afterload but unaffected by preload, whereas the echocardiographic measurement of right ventricular dimension is related to preload. Gated radionuclide ventriculography provides right ventricular data which is unique from that obtained by standard echocardiographic imaging. Also, gated radionuclide ventriculography has potential value as a noninvasive means of estimating a change in pulmonary artery pressure.  相似文献   

RADIOGRAPHY REVIEW: THE VASCULAR AND BRONCHIAL PATTERNS OF PULMONARY DISEASE     

Carole W.  Myer  DVM  MS 《Veterinary radiology & ultrasound》1980,21(4):156-160

Pulmonary blood vessels account for the majority of radiographically visible structures in normal lung. The vascular pattern of pulmonary disease is characterized by changes in vessel size, shape, contour. Changes in size can be classified as hypo vasularity (decreased size) or hyper vascularity (increased size). The pulmonary arteries and veins may be affected separately or simultaneously. In normal lung, the bronchial structures peripheral to the hilar area are not seen clearly. The bronchial pattern of pulmonary disease is characterized by alteractions in bronchial wall thickness and dinsity, or in bronchial lumen diameter. Mixtures of the four lung patterns, i.e. , alveolar, interstitial, bronchial, and vascular, occur frequently. The lung radiographic pattern in an individual animal depends not only on the disease process present, but also on the stage of the disease during which they are radiographed.  相似文献   

Evalution of an Epidural Intracranial Pressure Monitoring System in Cats     

Curtis W. Dewey DVM  MS  Cleta S. Bailey DVM  PhD  Steven C. Haskins DVM  MS  Philip H. Kass DVM  PhD  Dennis T. Crowe DVM 《Journal of Veterinary Emergency and Critical Care》1997,7(1):20-33

The accuracy of an inexpensive, easily implantable, epidural intracranial pressure (ICP) monitoring system was assessed in six normal cats by comparing measurements from this system to those obtained with a fiberoptic intraparenchymal monitoring system. The epidural monitoring system consisted of a three-way stopcock and saline-filled extension tubing, connected to a standard blood pressure transducer. Each cat was placed under halothane anesthesia and mechanically ventilated. Both an epidural and a fiberoptic intraparenchymal monitoring device were placed in the left cranium of each cat; correct placement was verified by computed tomography. Mean ICP values were simultaneously recorded from both monitoring devices. After obtaining baseline ICP measurements, the ICP was manipulated via ventilation, jugular compression, and pharmacologic agents. Arterial blood pressure levels, arterial blood gas values, end-tidal carbon dioxide levels, and end-tidal halothane levels were recorded throughout the study. Cerebral perfusion pressure was calculated for each level of ICP. Repeated measures analysis of variance method was used to compare mean ICP values between the two monitoring systems. No significant differences in ICP values obtained from the two systems were found (p>0.05) at any level of ICP. The results of this study show that the epidural monitoring system is a reliable alternative to the fiberoptic intraparenchymal ICP monitoring system in normal cats. The accuracy of the epidural monitoring system in pathologic states needs to be investigated.  相似文献
