Aortic Abdominal Aneurysm Blood Pressure for Endograft Function Assessment

Published: August 9, 2026Updated: August 16, 2026

This test measures blood pressure in the abdominal aorta after an endovascular stent graft (a tube placed inside your aorta to repair an aneurysm). It helps doctors monitor how well the graft is working and whether blood pressure is safely distributed around it.

Quick summary

["This test ensures your aortic stent graft is functioning properly and protects your blood pressure from abnormal pressures near the graft site."]

Why This Test Is Done

Doctors may order this test after you’ve had an endovascular aneurysm repair (EVAR) to check if the stent graft is holding your blood pressure at safe levels. It’s especially important if you have symptoms like back pain, swelling, or unusual fatigue, which could signal complications.

What to Expect Before the Test

No special preparation is needed. You’ll likely have a small tube inserted into an artery in your arm or groin to draw blood. The blood is then sent to a lab for analysis.

What the Results Mean

Results compare your blood pressure in the abdominal aorta to what’s expected after an endograft. Abnormal readings may indicate issues like improper graft placement, leaks, or high pressure near the graft.

Common Causes of Abnormal Results

Results outside expected ranges could be due to graft malposition, endoleaks (unintended blood flow around the graft), or other vascular issues. Your doctor will discuss these findings with you during your follow-up visit.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How often will I need this test?
This test is usually done during your follow-up visits after EVAR, often every few months or as recommended by your doctor. The timing depends on your graft type, health, and symptoms.
What if my blood pressure is too high or low near the graft?
If your results show unsafe blood pressure, your doctor may adjust your medications, reposition the graft, or recommend further imaging to fix the issue. You’ll work closely with your vascular team to manage this.
Can I eat or drink before this test?
Yes, you can eat and drink normally before this test. No fasting is required.
