Abstract

CASE DESCRIPTION

A 12-year-old 32-kg neutered female crossbreed dog was treated for a large lumbosacral skin defect.

CLINICAL FINDINGS

The dog had sustained multiple, penetrating dog bite wounds to the lumbosacral and gluteal regions 5 days earlier. The referring veterinarian had initiated treatment with amoxicillin–clavulanic acid, which was continued at a dosage of 8.75 mg/kg, SC, every 24 hours at the referral hospital. Examination of the skin defect revealed a large subcutaneous abscess in the dorsal lumbosacral region with draining perimeter tracts at the wound margin. The partial-thickness wound measured 24 × 35 cm and had multifocal regions of necrosis extending caudally from the dorsal aspect of the T11 vertebra to the tail base. The skin defect was bounded by discolored and necrotic skin edges.

TREATMENT AND OUTCOME

The dog underwent extensive soft tissue wound reconstruction. A single, large, meshed full-thickness free skin graft was harvested from the left dorsolateral aspect of the thorax and grafted to the dorsal lumbosacral region, thereby enabling successful closure of the wound defect. Primary healing of the wound eventually occurred, without postoperative complications.

CLINICAL RELEVANCE

Use of a large, meshed full-thickness free skin graft led to a satisfactory outcome for this dog but required challenging postoperative management. Application of single, large, meshed full-thickness free skin grafts may be an option to manage large skin deficits in the lumbosacral area in dogs.

Abstract

OBJECTIVE

To evaluate ultrasound-guided placement of an anchor wire (AW) or injection of methylene blue (MB) to aid in the intraoperative localization of peripheral lymph nodes in dogs and cats.

ANIMALS

125 dogs and 10 cats with a total of 171 lymphadenectomies.

PROCEDURES

Medical records of dogs and cats that underwent peripheral lymphadenectomies with or without (N) the AW or MB localization technique were reviewed. Data retrieved included clinical, surgical, and histologic findings. The proportions of successful lymphadenectomies, lymph node characteristics, and complications among the 3 groups were analyzed.

RESULTS

143 (84%) lymph nodes were successfully excised. Lymphadenectomy success was significantly affected by the localization technique, with 94% for group AW, 87% for group MB, and 72% for group N. Lymph node size was smaller in groups AW and MB, compared with group N. Duration of lymphadenectomy was shorter in group AW, compared with groups MB and N, and in group MB, compared with group N. Intra- (7%) and postoperative (10%) complications and final diagnosis did not significantly differ among groups.

CONCLUSIONS AND CLINICAL RELEVANCE

Both lymph node localization techniques were highly successful and reduced surgery time, compared with unassisted lymphadenectomy. Specifically, these techniques were effective for localization of normal-sized and nonpalpable lymph nodes and were efficient and practical options for peripheral lymphadenectomies, particularly for those that were small or nonpalpable.
