A retrospective study of 54 consecutive patients who were admitted to our hospital with a diagnosis of
AchA aneurysm and treated with EVT was performed. The variations and anatomy of the
AchA and the outcomes of EVT for
AchA aneurysms were analyzed.
Result: The 54 patients were aged 35-82 years (mean age, 56.1 ± 19.7 years) and included 32 females (59.3%, 32/54). Regarding
AchA anatomy, 63.5% of AchAs had a typical S-shaped course. The diameter of the
AchA origin averaged 0.8 ± 0.3 mm. Of all the
AchA aneurysms, 51.9% were ruptured. The diameter of
AchA aneurysms averaged 4.1 ± 2.4 mm. Moreover, 40.7% of 54 cases had multiple
aneurysms. EVT was assisted with stenting for 25.9% of 54
AchA aneurysms. An immediate Modified Raymond-Roy Classification grade of I was obtained in 96.3% of
AchA aneurysm cases. After EVT, the ischemic complication rate was 13%. In total, 83% of patients had good outcomes, with a Glasgow Outcome Scale score of 4-5. Follow-up angiography showed acceptable treatment results in this study.
Conclusion: The study showed that the
AchA had a complex angiographic anatomy in cases with
aneurysms at the origin of the vessel and that the anatomical features can be helpful in EVT. EVT for
aneurysms at the origin of the
AchA had good outcomes.
