CTA abdominal aorta with lower extremity runoff


Strengths
Pre-stent, angioplasty or surgical evaluation or in acutely ischemic patient. Includes 3D image reconstruction.
Limitations
MRA also very good for pre-procedural assessment and options exist for non-contrast study; If just screening for PVD, consider arterial US (very sensitive and can quanlify degree of overall compromise, but has less assessment of specific stenoses).
Contraindications
1) Allergy to contrast, but we will premedicate patient as necessary; 2) IV contrast will be dose-adjusted dependent upon creatinine clearance.
CPT Code
75635
Exact format for order to be authorized
