Abstract
A very small aneurysm arising from the posterior wall of the A1 segment of the left anterior cerebral artery (ACA) was found incidentally in a 60-year-old female patient who presented with headaches and diplopia due to a large right posterior communicating artery aneurysm (PcomA) with mass effect. The A1 aneurysm was treated using an endovascular flow diversion technique with a p48 Flow Modulation Device (phenox). The patient had a good clinical and angiographic outcome. Angiography confirmed that the aneurysm had been completely excluded while the anterior cerebral artery remained patent. The various treatment criteria and endovascular methods available to treat very small aneurysms and enable flow diversion in small vessels distal to the circle of Willis are the main topics of this chapter.
