The conventional anatomical study of specimens requires cutting processes which destruct the limited specimens. A non-destructive method, namely an ultrasonography, can be used to assess the anatomical organ information of those specimens. The aim of this research is to analyse the macroanatomy of the female reproductive organ in the Sunda porcupine (Hystrix javanica), using ultrasonographical imaging. In this study, four formaldehyde-fixed reproductive organ specimens of the Sunda porcupine were used. A 10–12 MHz linear ultrasound transducer was utilized to provide an imaging format of both longitudinal and transversal views. Photographic images were then used as comparison with a sonographic image. The results show that the ultrasound image of the Sunda porcupine reproductive organ soft tissue was hypoechoic, the lumen and antrum follicles were anechoic, while atretic follicles and the mons pubis were hyperechoic. Generally, the size of the organ was not significantly different between photographical and ultrasonographical imaging (p > .05). In conclusion, ultrasound images can be utilized for anatomical studies of the Sunda porcupine reproductive organs without destructing the specimen. 相似文献

ObjectiveTo provide ultrasonographic mapping of the axillary region of dogs to facilitate identification of the major branches of the brachial plexus in relation to the axillary artery.Study designProspective study.AnimalsA total of two dog cadavers and 50 client-owned, healthy dogs weighing >15 kg.MethodsIn Phase 1, anatomical dissections were performed to identify the relation of the major brachial plexus nerves to the axillary artery. In Phase 2, with the dogs in dorsal recumbency with thoracic limbs flexed naturally, the axillary space was scanned using a linear array probe oriented on the parasagittal plane until the axis transverse to nerves was found. Then, the transducer was rotated to a slight lateral angle approximately 30° to midline. The examination aimed to identify the axillary artery and the musculocutaneous, radial, median and ulnar nerves in addition to determining their position and distribution in four predefined sectors.ResultsThe musculocutaneous nerve was observed in all animals cranial to the axillary artery. The radial, ulnar and median nerves were distributed around the axillary artery, with >90% on the caudal aspect of the axillary artery (sectors 1 and 2).Conclusions and clinical relevanceUltrasonography identified the location of the brachial plexus nerves near the studied sectors, providing useful guidance for performing a brachial plexus nerve block. 相似文献

ObjectiveTo evaluate the use of ultrasound for identifying the site for needle puncture and to determine the depth to the epidural space in obese dogs.Study designProspective study in dogs undergoing elective orthopedic surgery.AnimalsA group of seven obese Labrador male dogs aged 6.93 ± 2.56 years and weighing 46.5 ± 4.1 kg (mean ± standard deviation).MethodsThe anesthetic protocol for these dogs included epidural anesthesia. With the dogs anesthetized and positioned in sternal recumbency with the pelvic limbs flexed forward, ultrasound imaging was used to locate the lumbosacral intervertebral space. Intersection of dorsal and transverse lines about the probe identified the point of needle insertion. A 17 gauge, 8.9 cm Tuohy needle was inserted perpendicularly through the skin and advanced to the lumbosacral intervertebral space. The number of puncture attempts was recorded and needle depth was compared with skin to ligamentum flavum distance.ResultsEpidural injection was performed in all dogs at the first attempt of needle insertion. The distance from skin to epidural space was 5.95 ± 0.62 cm measured by ultrasound and 5.89 ± 0.64 cm measured with the Tuohy needle. These measurements were not different (p = 0.26). A highly significant correlation coefficient of 0.966 between measurement techniques was obtained (p < 0.001).Conclusions and clinical relevanceUltrasound imaging identified the point of needle insertion for lumbosacral epidural injection in seven obese dogs. The results indicate that ultrasound can be used to locate the lumbosacral intervertebral space and identify an appropriate point for needle insertion to perform epidural injection. 相似文献
