Summary
Preoperative vascular mapping using color Duplex scanning improves planning for Deep Inferior Epigastric Perforator (DIEP) and Thoracodorsal Artery Perforator (TAP) flaps. Unidirectional Doppler flowmetry is reliable for Superior Gluteal Artery Perforator (S-GAP) flap planning.
Area of Science:
- Plastic Surgery
- Vascular Anatomy
- Surgical Planning
Background:
- Perforator flaps are preferred for contour defects and tissue replacement.
- Deep Inferior Epigastric Perforator (DIEP), Superior Gluteal Artery Perforator (S-GAP), and Thoracodorsal Artery Perforator (TAP) flaps are routinely used.
Purpose of the Study:
- To enhance surgical strategy by evaluating preoperative vascular anatomy.
- To improve the speed and safety of reconstructive microsurgery procedures.
Main Methods:
- Color Duplex scanning was evaluated for 50 DIEP flap patients.
- Unidirectional Doppler flowmetry was assessed for 30 S-GAP and 11 TAP flaps.
- Sensitivity and positive predictive value of imaging techniques were analyzed.
Main Results:
- Color Duplex scanning is preferred for DIEP and TAP flaps due to variable anatomy.
- Unidirectional Doppler flowmetry is reliable for S-GAP flaps due to consistent vascular anatomy.
- Preoperative imaging aids in selecting appropriate flaps for reconstruction.
Conclusions:
- Tailoring preoperative imaging based on flap vascular anatomy optimizes surgical planning.
- Color Duplex scanning and unidirectional Doppler flowmetry are valuable tools in perforator flap surgery.
- Improved planning leads to safer and more efficient reconstructive procedures.
