Summary
A rare abdominal aortic aneurysm case showed a mural thrombus blocking the inferior mesenteric artery (IMA). Unusual blood flow within the thrombus suggested chronic aortic dissection.
Area of Science:
- Vascular Surgery
- Radiology
- Cardiovascular Medicine
Background:
- Abdominal aortic aneurysms (AAAs) are common vascular conditions.
- The inferior mesenteric artery (IMA) is a critical vessel supplying the colon.
- Occlusion of the IMA can lead to ischemic complications.
Observation:
- A patient presented with an infrarenal AAA.
- A mural thrombus within the aneurysm occluded the ostium of a patent IMA.
- An accessory aneurysmal lumen within the thrombus supplied the IMA retrogradely.
Findings:
- Calcifications were noted within the mural thrombus.
- The retrograde IMA filling pattern was unusual.
- The findings raised suspicion for chronic aortic dissection.
Implications:
- This case highlights an atypical presentation of AAA.
- Understanding unusual IMA supply patterns is crucial for surgical planning.
- This morphology may indicate underlying chronic aortic dissection, requiring specific diagnostic considerations.
