Ultrasonographic Technique and Appearance of Adrenal Gland in Neonatal Foals: A Pilot Study
No full textAbnormal adrenal activity is involved in several neonatal diseases. Objectives of this pilot study were to assess the feasibility to investigate the adrenal gland in neonatal foals using the sonographic technique and to describe the ultrasonographic appearance. Eighteen neonatal foals less than 10 days of age were included in this study. Adrenal gland ultrasound was performed with a transcutaneous abdominal approach; anatomic localization, shape, and appearance were recorded. The right and left adrenal glands were located medial and cranial to kidney's hilus, between kidney and the caudal vena cava and ventral to the aorta, respectively. The right had a peanut shape in the majority; the left varied from crescent to oval-elliptic shapes. Ultrasonographically, the cortex (hypoechogenic) was well differentiated from the medulla (echogenic), except in three foals. Adrenal glands can be assessed consistently using abdominal ultrasonography in foals
Anatomical variation of the spinous and transverse processes in the caudal cervical vertebrae and the first thoracic vertebra in horses
No full textThere are scant data on the incidence of different anatomical variants of the equine caudal cervical spine, despite interest in cervical pathology

No full textThe purpose of this study was to describe the variation of the radiologic appearance of the caudal cervical
vertebrae in horses of different breeds, discipline and gender with cervical pathology and control horses
Arthroscopic anatomy of the equine cervical articular process joints
No full textSummary
Reason for performing study: Although arthropathy of the cervical articular process joints is
common, descriptions of the arthroscopic technique of the cervical articular process joint (APJs)
have not been reported previously. Objectives: To develop an arthroscopic approach to the APJs and to describe the arthroscopic anatomy of the APJs. Study design: Descriptive cadaver study and clinical case report. Methods: The regional anatomy was reviewed and the technique developed on fresh cadaver necks. A series of cadaveric APJs arthroscopies from C2-C3 to C6-C7 were performed t evaluate the procedure, which was then used 24 in 3 clinical patients. A description of the procedure and the potential complications encountered were recorded. Results: The equine APJs consist of cranioventral and caudodorsal recesses; a single entry pointat one of these recesses enables almost complete evaluation of cartilage surfaces and the synovial membrane and its villi. Successful entry into both APJ recesses was achieved in 22 cadaveric APJs and 5 APJs in the 3 clinical cases operated upon. An instrument portal was created to assess the feasibility of surgical arthroscopy. Complications were minor and dissection of the APJs following the arthroscopic exploration revealed that the cartilage and periarticular neurovascular structures were not damaged during the procedure. Conclusions: This study shows that arthroscopic examination of the APJs of equine cervical vertebra is feasible and can be performed in adult horses. Arthroscopy of the APJs may provide additional diagnostic information compared to conventional diagnostic techniques
Bilateral Rupture of the Palmar Carpal Ligament in a Horse Suffering from Acute Diaphragmatic Hernia
No full textA 20-year-old Argentinian gelding was evaluated for sudden weakness, muscular
tremors, tachypnea, and reluctance to move. On admission, a mild bilateral hyperextension
of the carpi was noticed. On the basis of the clinical, laboratory, and ultrasonographic
!ndings, a diagnosis of diaphragmatic hernia was made. During con!nement, the
hyperextension of the carpi worsened. Because radiographic examination of both carpi
revealed palmar-lateral diastasis of the accessory carpal bone, bilateral rupture of the
palmar carpal ligament (PCL) was suspected. Gross pathology con!rmed the diaphragmatic
hernia and the bilateral rupture of the PCL. Rupture of a PCL in a horse has been
previously described, and conformation of the forelimb of that horse was similar to that
of the horse in the case described in this article
Successful removal of a guidewire from the jugular vein of a mature horse
No full textThis case report describes the removal of a metal
guidewire that was lost accidentally in the jugular vein
during the placement of an indwelling catheter. The
proximal end of the guidewire was identified in the distal
third of the cervical region by radiography and
ultrasonography. The retained wire was removed
successfully by percutaneous fluoroscopically assisted
endovascular retrieval with a 4 pronged retrieval catheter
Frattura d’avulsione dell’origine della corda femoro-metatarsica (Peroneus Tertius) in un puledro
No full textIl peroneo terzo è un’importante porzione dell’apparato
di reciprocità che ha il compito di
coordinare la flessione e l’estensione del garretto
e della grassella. Le rotture del peroneo
terzo sono delle condizioni patologiche abbastanza
rare e l’evento traumatico ne costituisce
la causa principale. In questo lavoro è descritto
un caso di frattura d’avulsione dell’inserzione
prossimale del peroneo terzo e dell’estensore
lungo del dito in un puledro di 6 settimane.
L’esame clinico ha consentito da subito la diagnosi
di rottura della corda femoro-metatarsica
e gli esami radiografici ed ecografico hanno
permesso di stabilire le strutture interessate e
la localizzazione della lesione, e determinare
l’entità del danno. Il puledro è stato quindi sottoposto
ad artroscopia in anestesia generale,
per la rimozione dei frammenti osteocondrali
dall’articolazione femoro-tibiale laterale. A più
di un anno dall’intervento il puledro non presenta
zoppia e/o deformazioni della regione
della grassella, anche se la prognosi dovrà essere
rivalutata e rimodulata all’entrata in allenamento
del paziente
