Computed tomography angiography offers detailed 3D vascular imaging for upper extremity reconstruction planning. This cost-effective technique accurately visualizes anatomy, aiding surgical decisions and improving patient outcomes.

Area of Science:

  • Medical Imaging
  • Vascular Surgery
  • Orthopedic Surgery

Background:

  • Computed tomography angiography (CTA) is an advanced imaging modality.
  • It offers high-resolution, three-dimensional vascular visualization.
  • CTA provides excellent spatial relationships for bone and soft tissues.

Purpose of the Study:

  • To evaluate the utility of CTA in planning upper extremity reconstruction surgeries.
  • To assess the accuracy of CTA in depicting relevant anatomy for surgical intervention.

Main Methods:

  • Seventeen CTA scans were performed on 14 patients over 20 months.
  • All scans were conducted on an outpatient basis.
  • Contrast was administered intravenously via peripheral vein access.

Main Results:

  • All CTA studies accurately demonstrated pertinent anatomy.
  • Intraoperative findings consistently matched CTA imaging.
  • Information from two CTA studies significantly altered pre-operative surgical planning.
  • CTA averaged $1,140, significantly less than traditional angiography ($3,900).

Conclusions:

  • CTA is a valuable tool for pre-operative planning in upper extremity reconstruction.
  • It provides accurate anatomical detail cost-effectively compared to traditional angiography.
  • CTA can guide surgical decisions, potentially improving reconstructive procedures.
