Prognostic value of power doppler ultrasonography for equine superficial digital flexor tendon injury in thoroughbred racehorses. Vet J 2024; 306:106179. [PMID: 38880229 DOI: 10.1016/j.tvjl.2024.106179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 06/13/2024] [Accepted: 06/14/2024] [Indexed: 06/18/2024]
Abstract
The potential value of hypervascularity detected with power Doppler ultrasonography (PDU) within equine superficial digital flexor tendon (SDFT) as a prognostic factor of SDFT injury is not clear. The purpose of this study was to test the hypothesis that hypervascularity within SDFT is one of the risk factors for subsequent severe SDFT injury and to evaluate the prognostic value. A prospective cohort study of 97 Thoroughbred racehorses without any clinical signs of SDFT injury was conducted. Six variables of age, body weight, sex, the cross-sectional area of SDFT, PDU signal within SDFT and experience of steeplechase were assessed for the possibility of risk factors of subsequent SDFT injury in follow-up period of 1 year. Multivariable logistic regression analyses were used for assessment of the odds ratios (ORs) and 95 % confidence intervals (CIs) of SDFT injury. Multivariable logistic regression analysis revealed that the PDU signal within SDFT was a risk factor for the development of SDFT injury in follow-up period (P = 0.017). The adjusted OR of SDFT injury was significantly higher in PDU positive group than in PDU negative group (OR 3.17, 95 % CIs 1.20-8.35). Although further studies are required, these results would be useful for early detection and/or prevention of development for clinical severe SDFT injury.

Abstract
Thirty-seven pathologic Achilles tendons from 27 patients were investigated by a three-dimensional (3-D) power Doppler ultrasound system. Both the volume of the neovascularity (VON) and the volume of Achilles tendon (VOAT) were investigated. VON-VOAT index (VVI), as the normalization of the neovascularization, was accordingly calculated. Patient's clinical indications were assessed using the visual analog scale for pain (VAS) and Victorian Institute of Sport Assessment Achilles (VISA-A). Relationships between VAS and VON, VISA-A and VON, VAS and VOAT, VISA-A and VOAT, VAS and VVI, and VISA-A and VVI, were statistically analyzed. The vascular mapping within and surrounding the symptomatic Achilles tendons was investigated. 97.3% of the Achilles tendons were found to have neovascularization. In 55.6% of these Achilles, the neovascularity was associated with the location of thickening. The VAS was found to be positively correlated with the VON and the VVI, the VON was found to be independent from the VOAT.
