Recumbency decreases mare and foal survival following in-hospital dystocia management.

Background: Mare and foal survival are increased with prompt dystocia management. Data regarding mortality outcomes in mares and foals, when mares are recumbent at admission for dystocia resolution, are scarce.

Objectives: To evaluate recumbency at hospital admission as a risk factor for survival of mares and foals following dystocia management.

Sales and race performance of juvenile Thoroughbreds with surgically corrected large colon displacements.

Background: Juvenile Thoroughbreds can be expensive to raise and train to race. Part of the economic return in these juveniles are the weanling, yearling and 2-year-old in training sales at which major surgeries must be declared.

Objectives: To determine if surgically corrected large colon displacements were associated with a reduction of sales price and racing performance.

Prognosis for survival to discharge and racing performance in Thoroughbred foals treated for single joint septic arthritis (2009-2016).

Background: Haematogenous septic arthritis is a major cause of morbidity and mortality in foals. Previous research has demonstrated a variable prognosis for athletic performance in foals diagnosed with septic arthritis.

Objective: To determine the racing prognosis for Thoroughbred foals, 6 months of age or less with single septic joint of presumed haematogenous origin without recognised systemic sepsis or other serious comorbidity compared with a group of maternal sibling controls.

Preoperative computed tomographic evaluation of neonatal foals with rib fractures.

Objective: To compare ultrasonographic and computed tomographic findings in neonatal foals prior to surgical repair of rib fractures as well as postoperative outcomes in foals with and without preoperative thoracic computed tomography (CT). Study design Retrospective cohort study. Sample population 43 neonatal foals undergoing surgical treatment of rib fractures between 2013 and 2021.

Comparative results of 3 treatments for medial femoral condyle subchondral cystic lesions in Thoroughbred racehorses.

Objectives: To compare 3 different methods for treatment of medial femoral condyle (MFC) subchondral cystic lesions in Thoroughbred horses <24 months old based on the criterion of ability to race post-treatment.

Study Design: Retrospective cohort study.

Animals: Thoroughbreds (n = 107, age < 24 months) diagnosed with MFC subchondral cystic lesions.

The impact of grade of laryngeal function immediately prior to laryngoplasty and ipsilateral ventriculocordectomy on postoperative performance: 623 Thoroughbred racehorses (1998-2013).

Background: There is persistent concern among some trainers, owners and veterinarians regarding the effect of preoperative laryngeal function grade on the outcome of laryngoplasty and ventriculocordectomy (LPVC).

Objectives: To determine the effect of laryngeal function grade prior to LPVC on postoperative performance.

Study Design: Retrospective case-series.

Osteochondral fragments of the pastern joint at the origin of the collateral ligament of the distal sesamoid bone: performance after arthroscopic removal (2000-2015).

Objective: To describe the presence of fragments in the dorsal proximal interphalangeal (PIP) joint and to report flat racing performance after surgical treatment.

Study Design: Retrospective study.

Sample Population: Thirty-nine affected thoroughbred flat racehorses and 169 age- and sex-matched maternal siblings.

Preliminary heritability of complete rotation large colon volvulus in Thoroughbred broodmares.

Large colon volvulus (LCV) is a life-threatening form of colic that occurs when the large colon rotates 360° or more on its axis, resulting in colonic distention and ischaemia. Any horse can suffer from LCV, but the risk is greatest for periparturient Thoroughbred broodmares; the objective of this study was to estimate the heritability of LCV in these horses. The criteria for classification as an LCV case were being a Thoroughbred broodmare from one of three farms in central Kentucky and having had surgical correction for LCV.

End-to-Side Versus Side-to-Side Jejunocecostomy in Horses: A Retrospective Analysis of 150 Cases.

Objectives: To determine factors associated with postoperative reflux, postoperative colic, repeat celiotomy, and survival in horses after end-to-side (E2S) or side-to-side (S2S) jejunocecostomy.

Study Design: Retrospective, multicenter study.

Sample Population: Horses (n = 150).

Evaluation of survival rate and athletic ability after nonsurgical or surgical treatment of cleft palate in horses: 55 cases (1986-2008).

Objective: To determine survival rate and athletic ability after nonsurgical or surgical treatment of cleft palate in horses.

Design: Retrospective case series.

Animals: 55 horses with cleft palate.

Survival rates of mares and foals and postoperative complications and fertility of mares after cesarean section: 95 cases (1986-2000).

Objective: To assess survival-to-discharge rates of mares and foals and postoperative complications and fertility in mares following cesarean section (C-section).

Design: Retrospective case series.

Animals: 95 mares.

Resection and anastomosis of the descending colon in 43 horses.

Objectives: To determine (1) the short- (to hospital discharge) and long- (>6 months) term survival, (2) factors associated with short-term survival, and (3) the perioperative course for horses with resection and anastomosis of the descending colon.

Study Design: Multicentered case series.

Animals: Horses (n=43) that had descending colon resection and anastomosis.

Endoscopic evaluation of arytenoid function and epiglottic structure in Thoroughbred yearlings and association with racing performance at two to four years of age: 2,954 cases (1998-2001).

OBJECTIVE-To determine the association between results of endoscopic evaluation of arytenoid function (AF) and epiglottic structure (ES) in Thoroughbred yearlings and racing performance at 2 to 4 years of age. DESIGN-Retrospective case series. ANIMALS-2,954 Thoroughbred yearlings.

Selected urogenital surgery concerns and complications.

This article discusses selected urogenital surgeries. The discussion focuses on perioperative concerns and complications. The ideal approach to addressing complications resulting from disease processes or surgery is to avoid them.
