Periprocedural vascular access complications associated with percutaneous femoral arterial access using the modified Seldinger's technique in dogs during cardiac catheterization: a single-center experience.

BACKGROUND

The primary objective of this study is to evaluate the peri-procedural major and minor complications associated with percutaneous femoral arterial access using modified Seldinger's technique in dogs that underwent cardiac catheterization.

METHODS

Medical records of 62 client owned dogs that underwent percutaneous femoral arterial access for interventional cardiac procedures were retrospectively evaluated. Post-procedural manual compression was used for hemostasis. Peri-procedural vascular access complications (that occurred from procedure time to discharge) were evaluated. Vascular access complications were divided into two groups: minor complications that did not require specific therapy and major complications that did require an intervention to address the complication associated with vascular access.

RESULTS

The minor complication rate was 30.6% (19/62) with most dogs experiencing minor bruising and small hematomas. The major complication rate was 3.2% (2/62). Both major complications were associated with bleeding with one dog requiring blood transfusion and the other dog requiring fluid therapy. No peri-procedural mortality associated with vascular access was noted.

CONCLUSION

This retrospective study suggests that percutaneous femoral arterial access using the modified Seldinger's technique with post-procedural manual compression for hemostasis is viable option for vascular access during cardiac catheterization and associated with no peri-procedural mortality in dogs. The lower rate of complications noted in this study may be related to operator experiences and as such complication rate at a single center may not reflect the experience at other centers.
