Laparoscopic intra-abdominal ligation of the testicular artery following castration in a horse.

A 364-kg (800-lb) 1-year-old mixed-breed horse was admitted for treatment of uncontrolled bleeding after castration. Multiple attempts to ligate the testicular artery through the scrotal incisions prior to referral had been unsuccessful. Because of the owner's concerns about cost, an attempt was made to control the bleeding by applying pressure to the inguinal region and administering formalin IV.

The effect of oral isoxsuprine and pentoxifylline on digital and laminar blood flow in healthy horses.

Objective: To quantitate blood flow in the palmar digital artery and dorsal laminae of the hoof in standing, unmedicated, nonsedated horses, and in horses treated with oral isoxsuprine, oral pentoxifylline, and intravenous acetylpromazine as a positive control.

Study Design: Experimental study; treatments administered in a random cross-over design.

Animals: A total of 6 healthy horses selected with at least one nonpigmented forelimb hoof wall and determined to be free of laminitis.

Endoscopy of the calcaneal bursa in horses.

Objective: To describe endoscopic approaches to the calcaneal bursa and clinical findings in 2 horses with calcaneal bursitis.

Study Design: Cadaver evaluations and retrospective case reports.

Animals: 12 cadavers and 2 adult horses.

Evaluation of digital and laminar blood flow in horses given a low dose of endotoxin.

Objective: To measure blood flow in the palmar digital artery and laminae corium, using ultrasonic and laser Doppler flowmetry, respectively.

Animals: 6 healthy horses.

Procedure: Digital blood flow and laminar perfusion, respectively, were measured by placing a flow probe around the palmar digital artery and a laser Doppler flow probe in a hole in the dorsal aspect of the hoof wall.

Bacterial culturing of ventral median celiotomies for prediction of postoperative incisional complications in horses.

Objective: The purpose of this study was to determine whether detection of bacterial contamination of ventral midline incisions was predictive of postoperative incisional complications in horses undergoing exploratory celiotomy for colic.

Study Design: Prospective study.

Animal Or Sample Population: Horses that had ventral median celiotomies for colic at Colorado State University between May 1, 1991 and April 30, 1993 were studied prospectively.
