Effects of head position on internal and external carotid pressures in standing sedated horses.

The effects of head position on internal carotid artery (ICA) and external carotid artery (ECA) pressures in standing sedated horses were evaluated in this study. The common carotid artery (CCA) was catheterized in 6 horses using an ultrasound-guided technique to facilitate placement of a pressure transducer within the ICA and ECA at the level of the guttural pouch. Transducer position was confirmed by endoscopic visualization.

Midbody penile urethrocutaneous fistula repaired by fistulectomy and urethral anastomosis in a stallion.

Case Description: A 12-year-old Friesian stallion was examined because of a 1-year history of preputial injury and urination through a urethrocutaneous fistula located at the midbody of the ventral aspect of the penis.

Clinical Findings: Physical examination revealed an opening with a clearly apparent mucocutaneous junction 12 cm from the distal opening of the urethra on the ventral left side of the penis. Endoscopic examination of the distal portion of the urethra confirmed a blind pouch with no communication with the fistula or proximal portion of the urethra.

Morcellation for testes extraction in horses undergoing standing laparoscopic cryptorchidectomy.

The major objective of this study was to describe the use of morcellation for standing laparoscopic cryptorchidectomy in 30 client-owned horses. A second objective was to describe a laparoscopic-assisted standing scrotal technique for removal of a descended testis in unilateral cryptorchids. Morcellation for extraction of abdominal testes is effective, efficient, and well-tolerated.

Use of a motorized morcellator for elective bilateral laparoscopic ovariectomy in standing equids: 30 cases (2007-2013).

Objective: To describe the use of a motorized morcellator for elective bilateral laparoscopic ovariectomy in standing equids and to evaluate long-term outcome.

Design: Retrospective case series.

Animals: 30 equids (20 horses, 9 mules, and 1 pony).

Imaging diagnosis--muscular hypertrophy of the small intestine and pseudodiverticula in a horse.

A 14-year-old Thoroughbred gelding was presented for chronic colic and weight loss. Transcutaneous and transrectal abdominal ultrasonography revealed distended, thickened small intestine with primary thickening of the muscularis and a focally more thickened loop with an echoic structure crossing the wall from the mucosa to the serosa. Visualization of diffuse thickening of the muscularis (muscular hypertrophy of the small intestine) and a focal lesion (pseudodiverticulum) helped clinicians make informed decisions.

Laparoscopic removal of a bladder urolith in a standing horse.

Case Description: An 11-year-old Arabian gelding was evaluated for hematuria, stranguria, and pollakiuria that had been observed for 1 week.

Clinical Findings: Transrectal palpation revealed a 5-cm firm round mass in the urinary bladder. Cystoscopy and transrectal ultrasonography confirmed the diagnosis of urinary bladder urolithiasis.
