AORTA – POST ENDOGRAFT

INDICATIONS: AAA Post Endograft, stent placement.“CTA: Aorta, PE. No need to do pre unless looking for acute intramural hematoma or looking at stent grafts.”

PATIENT PREP: NPO for solid food, water only, for 4 hours prior to scan

IV CONTRAST: 100mL Isovue 370 @ 4 mL/second

ORAL CONTRAST: None

POSITIONING: Feet First Supine

TOPOGRAMS: AP & Lateral

SCAN TYPE: Spiral/Helical

NOTES: FOR ENDOGRAFT ONLY: Do UnEnhanced Series. Also do Delay Series through the graft area to check for a leak.
