Preoperative imaging like computed tomographic and magnetic resonance angiography improves free flap surgery outcomes. Understanding vascular anatomy pre-surgery enhances results and reduces operating time.

Area of Science:

  • Plastic Surgery
  • Vascular Surgery
  • Radiology

Background:

  • Perforator-based free flaps depend on specific dominant vessels for viability.
  • Accurate preoperative vascular anatomy assessment is crucial for successful flap outcomes.
  • Surgical planning benefits from advanced imaging techniques.

Purpose of the Study:

  • To highlight the importance of preoperative vascular imaging in free flap surgery.
  • To discuss the role of computed tomographic angiography and magnetic resonance angiography in surgical planning.
  • To emphasize the need for understanding technical considerations in cross-sectional imaging.

Main Methods:

  • Review of preoperative imaging modalities for free flap planning.
  • Focus on computed tomographic angiography (CTA) and magnetic resonance angiography (MRA).
