Anterior communicating artery aneurysm (ACOM aneurysm)

Aneurysms in the Anterior communicating artery, also referred to as ACOM aneurysms, are among the most common intracranial aneurysms. The presence of an ACOM aneurysm correlates with patient age, the angle between the anterior communicating artery and the A2 segment of the Anterior cerebral artery, and a smaller vessel diameter of the ACOM complex[^1].

History

The first operative treatments of ACOM aneurysms described in the literature were performed as early as 1933 and 1936 using Muscle wrapping [^2].

Imaging

The gold standard for imaging aneurysms is digital subtraction angiography. Depending on the size of the aneurysm, it may already be visualized on CT angiography.

Treatment

Anterior communicating artery aneurysms can be treated microsurgically with clipping or by endovascular means. The treatment modality should be selected according to the aneurysm’s anatomical characteristics.
