Galliano et al: Subcutaneous vascular access port implantation in the axillary or femoral/external iliac vein at the time of full limb amputation in dogs
Veterinary Surgery 7, 2022

🔍 Key Findings

SVAPs placed in axillary (aSVAP) or femoral/external iliac veins (fSVAP) during limb amputation remained functional in 92.3% and 100% of cases, respectively.
Complication rates were lower in aSVAP (23.1%) and fSVAP (0%) compared to jSVAP (47.4%), although not statistically significant (P = .12).
No catastrophic complications occurred with aSVAP or fSVAP; 2 deaths occurred with jSVAP due to port-related issues.
Infection-related port removal was needed in 1 aSVAP (7.7%) and 2 jSVAPs (10.5%) — no removals were required in fSVAPs.
Tip placement of the catheter (e.g., right atrium vs. vena cava) did not correlate with complications (P = .66).
Shorter surgical time likely with aSVAP/fSVAP as they use the same surgical field as the limb amputation.
Survival time median was similar across groups (jSVAP: 177 days, aSVAP: 125 days, fSVAP: 122 days).
SVAP implantation during limb amputation offers a practical and safe alternative to separate jugular placement.

Multiple Choice Questions on this study

In Galliano 2022 et al., on vascular access ports, which group had the highest rate of major and catastrophic complications?

A. aSVAP

B. fSVAP

C. jSVAP

D. All equal

E. Not reported

Answer: jSVAP

Explanation: jSVAP had 2 catastrophic and 3 major complications, including sepsis and port dislodgement.

In Galliano 2022 et al., on vascular access ports, what was one potential benefit of placing the SVAP during limb amputation compared to a separate jugular procedure?

A. Lower cost

B. Higher functionality

C. Fewer anesthetic risks

D. Shorter surgical time

E. Reduced sepsis risk

Answer: Shorter surgical time

Explanation: Using the same surgical field avoids a second surgical site, potentially reducing total procedure time.

In Galliano 2022 et al., on vascular access ports, what was the most frequent minor complication observed?

A. Thrombosis

B. Seroma formation

C. Temporary loss of catheter patency

D. Huber needle malfunction

E. Catheter migration

Answer: Temporary loss of catheter patency

Explanation: Temporary loss of patency occurred in 5 cases and was the most common minor complication.

In Galliano 2022 et al., on vascular access ports, which factor did **not** correlate with the development of complications?

A. Site of implantation

B. Number of uses

C. Catheter tip position

D. Port size

E. Breed

Answer: Catheter tip position

Explanation: No statistical correlation was found between catheter tip location and complications.

In Galliano 2022 et al., on vascular access ports, what was the reported functionality rate of ports placed in the femoral/external iliac vein (fSVAP)?

A. 70%

B. 80%

C. 90%

D. 95%

E. 100%

Answer: 100%

Explanation: All 4 dogs with fSVAP had fully functional ports during follow-up.
