Computed Tomography Angiography for Preoperative Thoracoabdominal Flap Planning

Area of Science:

• Plastic Surgery
• Radiology
• Breast Reconstruction

Background:

• Mastectomy rates are rising, increasing demand for advanced breast reconstruction techniques.
• Deep Inferior Epigastric Perforator (DIEP) flaps offer reduced abdominal donor site morbidity but require significant surgical skill.
• Optimizing DIEP flap procedures is crucial for patient outcomes and healthcare efficiency.

Purpose of the Study:

• To evaluate the impact of preoperative computed tomography angiography (CTA) on deep inferior epigastric perforator (DIEP) flap breast reconstruction.
• To assess if CTA-guided planning improves clinical outcomes, operative time, and hospital stay.
• To determine the cost-effectiveness of incorporating CTA in DIEP flap procedures.

Main Methods:

• Retrospective analysis of patients undergoing DIEP flap breast reconstruction.
• Comparison of outcomes between patients who received preoperative CTA and those who did not.
• Detailed review of operative times, hospital length of stay, and complication rates.

Main Results:

• Preoperative CTA accurately visualizes deep inferior epigastric artery (DIEA) anatomy and perforator pathways.
• Patients undergoing CTA demonstrated improved clinical outcomes.
• Shorter operative times and reduced hospital length of stay were observed in the CTA group.
• Potential for decreased overall healthcare costs associated with DIEP flaps.

Conclusions:

• Preoperative CTA is a valuable tool for planning DIEP flap breast reconstruction.
• CTA facilitates targeted intraoperative microdissection, improving efficiency and outcomes.
• Further research into thoracic anatomy and recipient vessel imaging may enhance preoperative planning and customization.
