Summary
Free flap transfer complications decreased with experience. Microsurgical technique errors caused most flap failures, highlighting the need for improved objective monitoring methods like Laser-Doppler-flowmetry.
Area of Science:
- Plastic Surgery
- Microsurgery
- Surgical Complications
Background:
- Free flap transfer is a complex microsurgical procedure.
- Complications and failures can significantly impact patient outcomes.
- Evaluating the causes of failure is crucial for improving surgical techniques.
Observation:
- Nine cases of free flap transfer complications were analyzed.
- Six out of seven total flap necroses were attributed to technique and tactics in microsurgical procedures.
- One latissimus dorsi flap failure resulted from axillary and thoracodorsal vein thrombosis.
Findings:
- Flap failure rates appear to decrease with increased surgical experience.
- A dorsalis pedis flap was successfully salvaged by utilizing arterial inflow through a flap vein.
- Revision surgeries were unsuccessful in saving flaps, possibly due to reliance on capillary filling for monitoring.
Implications:
- Microsurgical technique and tactical execution are critical factors in free flap transfer success.
- Current monitoring methods relying solely on capillary filling may be insufficient.
- Laser-Doppler-flowmetry presents a promising objective method for enhanced flap monitoring and early complication detection.
