Preoperative CT angiography for free fibula transfer

Area of Science:

• Vascular Surgery
• Medical Imaging
• Reconstructive Surgery

Background:

• The necessity of preoperative imaging for free fibula flap harvest is debated.
• Traditional arteriography, the standard imaging method, carries risks and potential complications.
• There is a need for safer imaging alternatives to assess vascular anatomy before flap harvest.

Purpose of the Study:

• To evaluate the utility of CT angiography as a preoperative imaging modality for free fibula flap harvest.
• To assess the safety and accuracy of CT angiography in visualizing lower extremity vasculature.
• To determine if CT angiography can replace traditional arteriography, thereby reducing patient risks.

Main Methods:

• A cohort of 7 patients underwent CT angiography prior to free fibula flap harvest.
• CT angiography was utilized for detailed vascular imaging of the lower extremity.
• The procedure focused on assessing both arterial and venous circulation relevant to flap viability.

Main Results:

• CT angiography provided accurate visualization of the arterial and venous systems.
• The imaging quality was comparable to traditional angiography.
• No complications were reported from the CT angiography procedure or the subsequent fibula harvest.

Conclusions:

• CT angiography is a safe and effective noninvasive alternative for preoperative vascular assessment in free fibula flap surgery.
• This imaging technique accurately depicts lower extremity circulation, potentially mitigating risks associated with arteriography.
• The findings support the adoption of CT angiography for routine preoperative planning in free fibula flap procedures.
