The mean growth rate observed for celiac artery aneurysms that show enlargement is 1.09 mm per year.
Understanding Celiac Artery Aneurysm Growth
Celiac artery aneurysms, though rare, can enlarge over time. While not all celiac artery aneurysms exhibit growth, studies show that a significant portion—slightly over one-third of patients with radiological follow-up—experience aneurysmal enlargement.
The observed mean growth rate of 1.09 mm/year provides an insight into the typical progression for these enlarging aneurysms. It's important to note that despite this enlargement, clinical follow-up, which has been recorded for a mean of 31.2 months, has not documented cases of rupture or symptomatic disease associated with these aneurysms. This suggests a relatively benign natural history within this observed period for a substantial portion of these aneurysms.
Key Aspects of Celiac Artery Aneurysm Natural History
To provide a clearer picture, here are some key findings related to the natural history of celiac artery aneurysms:
| Aspect | Observation |
|---|---|
| Mean Growth Rate | 1.09 mm/year (for enlarging aneurysms) |
| Enlargement Frequency | Slightly over one-third of patients |
| Mean Clinical Follow-up | 31.2 months |
| Documented Rupture | None observed during follow-up |
| Symptomatic Disease | No documented cases during follow-up |
These insights help in understanding the typical behavior of celiac artery aneurysms, particularly regarding their growth pattern and clinical stability over a considerable follow-up period.
