The purpose of this study was to assess the impact of freezing and thawing on MR images of equine feet examined ex vivo. Nine equine cadaver digits were first imaged at room temperature (T0). Among the 9 digits, 3 (group 1) were imaged in a 3 Tesla MR system after one and after 2 freezing-thawing cycles. Digits of group 1 were thawed in a cold room at 4°C for 36h. Three other digits (group 2) were imaged after one freezing-thawing cycle. Digits of group 2 were thawed in a cold room at 4°C and then rescanned after 24h at room temperature. The last 3 digits (group 3) were scanned after one freezing-thawing cycle. Digits of group 3 were thawed at room temperature for 24h. Sequences used were Spin Echo (SE) T1, Turbo Spin Echo (TSE) T2 and proton density (PD), Short Tau Inversion Recovery (STIR), Double Echo Steady State (DESS), 3D Gradient Echo (GE) T1 and 2D GE T2*. Images obtained on the fresh limbs at room temperature were subjectively compared side by side to images obtained at the different freezing-thawing cycles. A quantitative analysis to assess signal change between examinations was realized by measuring signal to noise ratio (SNR). Visibility and margination of the anatomical structures of the foot and overall image quality were subjectively considered unchanged except for the hoof where the lamina was considered less visible distally after freezing and thawing in the GE T2* and in TSE T2 and PD sequences. Quantitative analysis demonstrated SNR changes in the bone marrow only in the distal phalanx in the SE T1 sequence when the feet were thawed at room temperature. When the feet were thawed in a cold room at 4°C, bone marrow SNR changes were present in the SE T1, GE T1 and TSE PD sequences. Signal changes were significant in the synovial recess when the thawing process was made at 4°C and not when the thawing process was at ambient temperature. The soft tissue structures and the hoof capsule showed significant changes with an increase of SNR, except in STIR, after freezing and thawing at 4°C and at room temperature. SNR changes in the soft tissues were mainly present in GE sequences. [less ▲]

Acepromazine (ACP) is a phenothiazine commonly used to sedate horses. Additionally, ACP exerts strong anti-inflammatory effects, which might have a therapeutic potential in horses suffering from systemic inflammatory response syndrome (SIRS). However, the ACP-induced vasodilation precludes its use in horses with SIRS-related cardiovascular compromise. The objective of this study was to test if the hemodynamic effects of the administration of 0,1 mg/kg of ACP could be counteracted by an intravenous infusion of norepinephrine (NOR) at 1ug/kg/min in healthy horses. In 5 healthy adult horses, a 15 minutes NOR IV infusion was administered 45 minutes after an injection of 0,1 mg/kg of ACP IV. The systolic arterial blood pressure (SAP) was non-invasively measured by Doppler sphingometry at the tail. Hemodynamics of the median artery of the left forelimb were studied using Doppler ultrasonography, through calculation of the vessel’s surface (SURF), diameter (DIAM), circumference (CIRC), and peak systolic velocity (PSV), end diastolic velocity (EDV), mean velocity (MV), volumetric flow (VF) and resistivity index (RI) of the flow. Both SAP and Doppler parameters were determined at regular intervals during the entire study. ACP induced a hypotension and a vasodilatation, that were evidenced by a significant rise of the SURF, DIAM, CIRC, PSV, EDV, MV and VF and reduction of the SAP and RI. During NOR infusion, all these ACP-induced hemodynamic changes were reversed. These findings suggest that a continuous IV NOR infusion at 1ug/kg/min is able to revert ACP-induced hypotension and vasodilation in healthy adult horses. [less ▲]

Foot pain is an important cause of lameness in horses. When horses with foot pain have no detectable radiographic abnormalities, soft-tissue assessment remains a diagnostic challenge without magnetic resonance (MR) imaging. Ultrasonography can provide an alternative to MR imaging when that modality is not available but the extent of changes that might be seen has not been characterized. We reviewed the ultrasonographic findings in 39 horses with lameness responding positively to anesthesia of the palmar digital nerves and without radiographically detectable osseous abnormalities. Thirty of the 39 horses had lesions affecting the deep digital flexor tendon (DDFT), 27 had abnormalities in the distal interphalangeal joint of which six had a visible abnormality in the collateral ligament. Ultrasonographic abnormalities were seen in the podotrochlear bursa in 22 horses and in the ligaments of the navicular bone in two horses. Abnormalities of the navicular bone flexor surface were detected in eight horses. In three of the 39 horses, only the DDFT was affected. The other 36 horses had ultrasonographic abnormalities in more than one anatomical structure. Based on our results, ultrasonographic examination provides useful diagnostic information in horses without radiographic changes. [less ▲]

The aim of this prospective study was to establish a protocol for fast localised abdominal sonography of horses (FLASH) admitted for colic. The FLASH protocol was then presented to clinicians without extensive ultrasound (US) experience to determine whether they could learn to use it in less than 15 min. The clinical subjects comprised 36 horses that had been referred for colic over a 2 month period. Each horse was examined at admission and FLASH findings at seven topographical locations were compared to serial clinical examinations, surgical and non-surgical outcomes, or with post-mortem reports. FLASH was able to show free abdominal fluid and abnormal intestinal loops, with a mean time of 10.7 min required to complete the protocol. The positive and negative predictive values of requirement for surgery of dilated turgid small intestinal loops using FLASH were 88.89% and 81.48%, respectively. The results suggested that FLASH is a technique that can be used in an emergency setting by veterinarians without extensive US experience to detect major intra-abdominal abnormalities in horses with colic.

Introduction/Aims The cisterna chyli (CC) is a dilated and bipartite portion of the lymphatic channels coursing intimately along the abdominal aorta in the retroperitoneal space.1 The appearance of the CC of the dog has been described on magnetic resonance imaging.2 The aim of this poster is to describe the ultrasonographic appearance of the CC in 2 dogs with chylous ascitis and in 2 healthy dogs. Methods Abdominal ultrasonography was realised with a 7.5MHz microconvex transducer. A right or left lateral dorsal approach was used. The aorta (together with the cranial mesenteric artery in normal dogs) was used as the main landmark to localize the CC. The dogs with chylous ascites were a 4 year old female american cocker spaniel, with immune-mediated hemolytic anemia and thrombocytopenia and a 1 year old, spayed female whippet with recurrent pancreatitis. The 2 healthy dogs were a 7 year old Beagle and a 9 year old Jack Russell. The abdominal ultrasonography was realised within 2 hours after the meal in the healthy dogs. Results The CC was seen as a hypoechoic structure, without detectable flow, dorsal and to the right of the aorta. The CC was easily visible in the 2 dogs with chyloabdomen while it was more difficult to localize in the healthy dogs. The CC was tubular on the longitudinal images. On transverse images, the CC is elliptic or semilunar and may partially surround the aorta. The maximal width of the CC measured on transverse images varied from 2-3mm in the 2 healthy dogs to 4-8mm in the 2 dogs with chyloabdomen. In 3 patients some efferent/afferent lymphatic vessels were seen as thin hypoechoic tubes converging on the CC. Shape and size of the CC in the same animal were seen varying during the same ultrasonography or between different exams. Discussion/Conclusion The CC is visible by ultrasonography in dogs. Its visibility depends on different conditions like disease of the lymphatic system3, quality and distance of the meal. [less ▲]

Introduction: The injuries of the suspensory ligament (SL) are important causes of lameness and financial losses in the equine industry. Ultrasound examination permitted to visualize some parts of the SL. The significance of “abnormal” findings is however not sufficiently known. Until now, few studies described the relationship between the ultrasonographic appearance and the exact morphology in histological sections. The aim of this study is to develop good techniques for cutting and staining the SL and to improve knowledge about the normal morphology of the SL. Methods: In this study, the SL of eight <sound> horses were collected. The body of the SL was divided in 3 thirds and sampling was realised within each third and between the thirds. The samples were embedded in paraffin or in Tissue-Tek for cryosections. The sections were stained with hematoxylin/eosin or Masson's trichrome. For 3 SL, ultrasounds were performed before sampling. The digital tip was maintained in physiological position owing to a press. Results: Most of the paraffin sections were shredded because of the hardness of the tissue. Cryosection revealed a better preservation of tissues. Only some freezing artifacts (holes) appeared on a few sections. Muscles fibers surrounded by adipose tissue containing blood vessels were present mainly in the proximal and medium third of the SL whereas they were not found in the distal third. The remaining structure look like a tendon and was composed of collagen fibers, stained in green with the Masson's trichrome coloration. Conclusions: This study permitted to develop cutting and staining techniques for the SL and helped to map the adipose, muscular and tendinous parts within the SL. It lays down the bases of subsequent studies that will concern ultrasonographically examined digital tips of sound and pathological horses of different breeds and ages. [less ▲]
