Aims and objectives
Compare the cost of two different approaches to the follow-up of endovascular repair (EVAR) of infrarenal abominal aortic aneurysm (AAA) using computed tomography angiography (CTA) (Fig.
1) and combining contrast enhanced ultrasonography (CEUS) with computed tomography (Fig.
Methods and materials
We included all the patients submitted to EVAR of infrarenal AAA who underwent at least one CEUS for post operative follow-up in the year of 2016.
The cost of imaging exams used in this period was analyzed.
We hypothetically substituted the cost of CEUS by the cost of CTA to create a new group.
Ten patients were included for analysis with a total of 29 exams.
Mean follow-up was of 202.2 days (+/- 51.2).
Median cost of imaging follow-up was US$1.160,57 (939,29-1.637,56).
CEUS is 40.5% less costly than CTA at our institution (US$432,76 versus US$727,80).
If the follow-up was only made with CTA,
median cost would be US$1.455,61 (1.455,61-1.637,56).
Including CEUS as a strategy for follow-up saves 26.5% of the costs (Fig.
Contrast enhanced ultrasonography is a more cost-effective strategy for the follow-up of endovascular repair of abominal aortic aneurysm and can save 26.5% of imaging exam expenses and do not expose patients to radiation and nephrotoxic contrast used in computed tomography angiography.
Contrast Enhanced Ultrasound can Replace Computed Tomography Angiography for Surveillance After Endovascular Aortic Aneurysm Repair.
