Evaluation of a selective neurectomy model for low urethral pressure incontinence in female dogs.

Objective: To develop a model of low urethral pressure incontinence and compare the relative contributions of the pudendal and hypogastric nerves with urethral function by performing selective neurectomy and ovariohysterectomy in dogs.

Animals: 19 healthy Foxhounds.

Procedure: Dogs were allocated into 2 groups.

Lobar holoprosencephaly in a Miniature Schnauzer with hypodipsic hypernatremia.

A 9-month-old male Miniature Schnauzer was examined because of a lifelong history of behavioral abnormalities, including hypodipsia. Diagnostic evaluation revealed marked hypernatremia and a single forebrain ventricle. The behavioral abnormalities did not resolve with correction of the hypernatremia, and the dog was euthanatized.

Flexor carpi ulnaris (humeral head) muscle flap for reconstruction of distal forelimb injuries in two dogs.

Objective: To describe the use of the humeral head of the flexor carpi ulnaris muscle as a rotational flap for reconstruction of distal antebrachial, carpal, and metacarpal injuries in two dogs.

Study Design: Description of clinical cases.

Results: Local rotation of the humeral head of the flexor carpi ulnaris muscle provided coverage of the carpal and carpometacarpal bones and joint structures exposed by soft tissue avulsion.

Effects of vascular pedicle ligation on blood flow in canine semitendinosus muscle.

Blood flow to the semitendinosus muscle was studied in 12 dogs after ligation of either the proximal or distal vascular pedicle and elevation of the muscle from its normal position. Using 15-micron-diameter radioactive microspheres, flow was measured at rest, 6 and 18 days after muscle elevation and pedicle ligation. Mean blood flow in the proximal region of the muscle 6 and 18 days after ligation of the caudal gluteal (proximal) pedicle was not significantly different from mean blood flow calculated in the middle and distal regions of the muscle.

Identification and categorization of the vascular patterns to muscles of the thoracic limb, thorax, and neck of dogs.

Vascular patterns to thoracic limbs, thorax, and neck muscles were studied in 10 dogs (20 limbs) to identify muscles most suitable for transposition in the treatment of large wounds. Gross dissection of injected specimens and angiography were used to identify vascular pedicles. Size and location of pedicles were generally consistent, and any variations would not interfere with most muscle transfers.
