Ten guinea pigs with an ovarian cyst had clinical signs of anorexia, alopecia, or depression. Ultrasonographic features of the 2- to 3-cm diameter fluid-filled cysts included compartmentalization and connection to the ovary. In two animals, a unilateral cyst was present, and in two others, the cysts were bilateral. Diagnosis of the disease by plain radiography is difficult because of the similar opacity of ovarian cysts, abdominal neoplasms, and trichobezoars. 相似文献

By the radiographic examination of pet and wild birds, veterinary clinicians may relatively easily obtain additional information that can be used routinely in their everyday diagnostic and therapeutic work. The first part of the present review summarizes the basic technical conditions of radiological examinations, analyses the radiographic features of healthy birds, and describes the procedure and radiological indications of contrast radiography. 相似文献

Two-dimensional echocardiographic (2DE) examination was performed on a horse with clinical signs of pericardial effusion. Thickening of the pericardium, excess amount of pericardial fluid, elevation of the cardiac apex, and right ventricular compression, characteristic of cardiac tamponade, could be seen on 2DE recordings. Fibrinous pericarditis was suspected by observation of fibrinous strands in the pericardial fluid and epicardial fibrin deposits. Echocardiographically guided pericardiocentesis was performed, and 4 L of fluid was removed from the pericardial sac. Streptococcus zooepidemicus was isolated from the fluid. Pericardiocentesis was repeated for 3 days, and medication was administered. Despite temporary improvement in cardiac function, the horse's condition deteriorated gradually, and euthanasia was performed on the ninth day of hospitalization. Necropsy revealed chronic serofibrinous pericarditis of traumatic origin, attributable to an intercostal stab wound entering the pericardium and the apical portion of the myocardium. 相似文献

Ultrasonographic linear and area measurements were performed on both kidneys of 15 clinically healthy dogs. Renal volumes were calculated from linear and area data applying three prolate ellipsoid models. Ultrasonographic volumes were then compared using linear regression analysis with kidney volumes measured in vitro by water displacement. In vivo ultrasonographic volumes had a statistically significant relationship with the in vitro volume. The highest correlation was provided by the single plane area method. There was also a correlation between body weight and ultrasonographically detected renal volume, suggesting that ultrasound imaging may be a useful method for assessment of renal volume changes in dogs with renal disease. 相似文献

The applicability of ultrasonography was studied in the diagnosis of lesions of the renal pelvis and ureter in 10 dogs. Ultrasonographic findings of processes associated with dilatation and concretion formation in the renal pelvis were described and the differential diagnosis of the lesions was discussed. The authors propose a new classification system for judging processes characterized by dilatation of the renal pelvis. Experience suggests that ultrasonography is an effective procedure in the diagnosis of certain diseases of the upper urinary tract in dogs. 相似文献

The second part of the review dealing with the diagnostic radiology of pet and wild birds discusses the indications of radiological examination, the interpretation of radiographs taken of pathological lesions, and the differential diagnosis of such lesions. Radiology has paramount importance in the diagnosis of diseases affecting the skeletal, digestive, respiratory, urogenital and cardiovascular systems. Certain diseases (shortage of grits, ovarian cysts) cannot be recognized without radiography. Other conditions (e.g. Macaw Wasting Disease, renal tumours, egg retention) require this complementary diagnostic method for confirmation of a suspicion based upon the clinical signs. Radiographic examination is also indicated for follow-up of the surgical management of bone fractures and for facilitating the implantation of transponders aimed at individual identification of the birds. 相似文献

Ultrasonographic examination of 40 pet guinea pigs was performed in the framework of this study. Preparation of the patient for ultrasonography and the examination procedure are described. Normal ultrasonographic findings of the abdominal organs including the liver, spleen, kidney and urinary bladder are presented and illustrated for the first time in this species. Ultrasonography was found to be a useful investigative tool in the diagnosis of abdominal diseases in guinea pigs. In comparison to other diagnostic methods like physical examination including palpation, haematological examination, radiography and diagnostic laparotomy, ultrasonography offers a rapid, non-invasive and reliable means of diagnosing abdominal diseases in this species. 相似文献
