Azygos distal anterior cerebral artery (Az.DACA) is a rare anatomical variant. This variant has been found to be associated with aneurysms in a significant proportion of patients. We present two cases of Az.DACA aneurysms associated with this anatomical variant with different branching patterns and the corresponding technical difficulties in clipping such aneurysms. Aneurysms associated with Az.DACA present unique technical challenges in proportion to the number of branches arising near the neck and should be managed at high volume centres with the best of facilities.

Article Synopsis
- * A systematic review and meta-analysis were conducted using databases like Cochrane Library and PubMed, identifying 48 relevant articles to assess the incidence of these ACA variations.
- * The analysis reveals that there were no statistically significant differences in the prevalence of ACA variations when comparing cadaveric (autopsy) studies to imaging studies.
