Ch. 65: Amputations

Question 1

Billas Vet Sx 2021

Incidence of and risk factors for surgical site infection following canine limb amputation

% developed SSI?
4 reasons more likely to develop SSI?

Answer 1

Thirty-one dogs (31/248, 12.5%) developed an SSI of the amputation site

More likely to develop SSI:
- pre-op bacterial infection 5.7x (vs. neoplasia)
- trauma as reason for amputation 4.5x (vs. neoplasia)
- wound classified as other than clean
- use of bipolar vessel sealing device (but NOT monopolar cautery)

Question 2

Nakano JAVMA 2022

Outcome of appendicular or scapular osteosarcoma treated by limb amputation in cats: 67 cases (1997-2018)

• % distant mets?
• location assoc with distant mets?
• MST?

Answer 2

Distant metastasis rate after amputation 42%

Humerus osteosarcoma sig associated with distant metastasis (OR 9.56)

Median survival time was 527 days

Question 3

Magidenko JAVMA 2022

Analysis of patient outcome and owner satisfaction with double limb amputations: 14 dogs and four cats

• most common indication?
• % O satisfaction?

Answer 3

Trauma most common indication 12/18 (67%)

Owner satisfaction score
- Very satisfied/excellent 14/18 (78%)
- Mildly satisfied 3/18 (17%)
- Strongly dissatisfied 1/18 (5%)

Question 4

Galliano VSURG 2022

Subcutaneous vascular access port implantation in the axillary or femoral/external iliac vein at the time of full limb amputation in dogs

• minor/major complication rates?
• which placement associated with euthanasia?
• difference in complication rate for placement?

Answer 4

Minor and major complications were recorded in 1/13 and 2/13 aSVAPs, 0/4 and 0/4 fSVAPs, and 3/19 and 4/19 of jSVAPs

Two dogs with jSVAPs were euthanized due to SVAP-related complications

No difference in complication rate was detected between groups
