Jugular venous thrombosis as a risk factor for exercise-induced pulmonary hemorrhage in thoroughbred racehorses.

Abstract: Exercise-induced pulmonary hemorrhage (EIPH) is one of the most commonly diagnosed disorders in racehorses. Many EIPH risk factors such as breed, age, high or low environmental temperature, and distance of the race have been studied in racehorses. Unassigned: The aim of this study was to study the relationship between EIPH and the presence of jugular vein thrombose in racehorses. Unassigned: Forty-eight thoroughbred racehorses randomly selected from animals with exercise intolerance due to respiratory disorders were enrolled in the present study. Clinical and tracheobronchoscopy examinations were done for EIPH grading. In addition, both jugular veins were examined using ultrasonography for vein thrombosis. Unassigned: It was noted during endoscopy that many cases suffered from laryngeal paralysis, and we were not able to assess the degree of laryngeal paralysis under sedation. About 40% of horses with exercise intolerance suffered from EIPH of varying degrees. Most cases of jugular vein thrombosis were of the chronic type, as local heat and pain were not observed. About 42% of the exercise-intolerant horses had jugular vein thrombose with most jugular vein thrombosis on the left side. Combined jugular veins thrombose and EIPH were found in about 25% of exercise intolerance horses, while 17% showed jugular vein thrombose without EIPH, and 41% showed no EIPH with the absence of jugular vein thrombose. Unassigned: The present study revealed that jugular vein thrombosis may cause disorders-associated damage to the vessels and anatomical structures close to it, such as the trachea causing EIPH.

This study explores the correlation between Exercise-Induced Pulmonary Hemorrhage (EIPH) and instances of jugular vein thrombosis in thoroughbred racehorses. The research reveals that horses suffering from jugular vein thrombosis may be more prone to EIPH due to potential damage to the trachea and nearby vascular structures.

Objective of the Study

  • The aim of the research was to investigate the link between EIPH, a common disorder in racehorses, and the presence of jugular vein thrombosis. EIPH has been studied in relation to various factors such as breed, age, environmental variables, and race distance. This study adds to the understanding of these potential risk factors.

Methodology

  • 48 thoroughbred racehorses were selected randomly for the study. All horses studied demonstrated exercise intolerance due to respiratory disorders.
  • Each horse underwent a clinical and tracheobronchoscopy examination to ascertain levels of EIPH. Also, both jugular veins were examined using ultrasonography to detect possible thrombosis.

Findings

  • Many horses were also found to suffer from laryngeal paralysis, which could not be fully assessed under sedation.
  • Approximately 40% of the horses with exercise intolerance demonstrated varying degrees of EIPH.
  • Around 42% of the exercise-intolerant horses had jugular vein thrombosis, most of which were on the left side.
  • About 25% of the exercise intolerant horses exhibited both jugular vein thrombosis and EIPH. By contrast, 17% showed thrombosis without EIPH, and 41% showed no EIPH or thrombosis.

Conclusions

  • The study suggests a connection between jugular vein thrombosis and EIPH in thoroughbred racehorses. The presence of a clot in the jugular vein can cause damage to adjacent structures like the trachea, leading to EIPH.
  • This research can provide valuable insights into preventive measures for reducing the incidence of EIPH in racehorses by detecting and treating jugular vein thrombosis at an early stage.
