Summary
This study developed a microvascular free flap using the deep circumflex iliac (DCI) artery and vein in cats. While some flaps failed due to technical issues or ischemia time, the DCI flap shows promise for reconstructing large wounds in felines.
Area of Science:
- Veterinary Surgery
- Microsurgery
- Anatomy
Background:
- Reconstructive surgery in cats often requires versatile flaps.
- The deep circumflex iliac (DCI) artery and vein offer potential for flap creation.
- Assessing the viability of a DCI-based cutaneous free flap in felines is crucial.
Purpose of the Study:
- To develop and evaluate the survival of a microvascular cutaneous free flap based on the ventral branch of the DCI artery and vein in cats.
- To determine the anatomical boundaries of the DCI angiosome in felines.
Main Methods:
- Phase 1 involved angiographic mapping of the DCI angiosome in feline cadavers.
- Phase 2 assessed the survival of island flaps based on the DCI angiosome in live cats.
- Phase 3 evaluated the survival of free DCI flaps transferred to a new location in cats.
Main Results:
- Angiography defined a large DCI cutaneous angiosome in the lateral femoral region.
- Island flaps demonstrated survival, but free flap survival was variable (60% success).
- Flap failure was associated with anastomosis issues, hemorrhage, and prolonged ischemia time.
Conclusions:
- The cutaneous DCI free flap is a potentially viable option for reconstructing large feline wounds.
- Shorter ischemia times may be critical for successful cutaneous free flap transfer in cats.
- Further clinical studies are needed to confirm the utility and optimize the technique.
