Three-Dimensional Venous Visualization with Phase-Lag Computed Tomography Angiography for Reconstructive Microsurgery

摘要

Background Most free flap reconstruction complications involve vascular compromise. Evaluation of vascular anatomy provides considerable information that can potentially minimize these complications. Previous reports have shown that contrast-enhanced computed tomography is effective for understanding three-dimensional arterial anatomy. However, most vascular complications result from venous thromboses, making imaging of venous anatomy highly desirable.
