“…This procedure may reduce pathologic blood flow by improving both the blood flow and perfusion pressure in the MCA territory, which would consequently constrict moyamoya arteries and possibly shrink distal aneurysms. 6 In these two patients, the anastomosis improved cerebral hemodynamics as measured by CT perfusion and the aneurysm was shown by DSA to have vanished, accompanied by deceased moyamoya vessels. This suggests that patients with developed collateral circulation following revascularization are at lower risk of aneurysmal rebleeding from the peripheral moyamoya vessels.…”

“…5 Peripheral aneurysms are caused by rupture of the pathological vessels that form a hematoma, and are regarded as pseudo-aneurysms due to their transient appearance on cerebral angiograms. 6 Rupture occurs due to persistent hemodynamic stress on dilated, fragile moyamoya vessels, 7 often occurring in the basal ganglia, thalamus or ventricles. 8 Major artery aneurysms grow slowly and do not disappear; they are often discovered around the circle of Willis.…”

“…Some authors have considered these lesions to be pseudoaneurysms. Aneu- rysms associated with moyamoya show differences in their evolution and location when compared with those in the general population [10][11][12]. However, clinical differ ences between the aneurysms in unilateral and bilateral moyamoya remain unclarified.…”

The occurrence of unilateral and bilateral moyamoya disease may be associated with intracranial aneurysms. These aneurysms are of two types: major-artery aneurysms and peripheral-artery aneurysms. The former arise at the circle of Willis and the latter are located mainly at either the moyamoya vessels or at the choroidal arteries. We analyzed 76 patients with cerebral aneurysms associated with moyamoya disease who were affected unilaterally or bilaterally. Of them, 10 cases were studied by our group and 66have been reported in other studies. The characteristics of the aneurysms were assessed. The frequency of aneurysms associated with moyamoya is 4-fold higher in unilateral than in bilateral moyamoya. Major-artery aneurysms are found mainly in the arterial complex of the anterior communicating artery-anterior cerebral artery in patients with unilateral moyamoya, and in the basilar artery in patients with bilateral moyamoya. When microaneurysms are taken into account, peripheral-artery aneurysms are more frequent than major-artery aneurysms. Our results suggest that aneurysms associated with moyamoya disease have some characteristics that should be taken into consideration when making comparisons with these lesions encountered in the general population.

“…However, Satoh et al reported a case of MMD associated with bilateral PcomA aneurysm, in which the aneurysms did not rupture during the 2-year follow-up period. MMD progressed and the ICA was occluded, resulting in involvement of the bilateral PcomA and disappearance of the PcomA aneurysms (9). Adams et al reported one case of MMD with PcomA aneurysm.…”

“…Eventually, the PcomA will suffer from too much blood flow, possibly resulting in the formation of an aneurysm (7). Expansion of the PcomA with aneurysm after MMD formation is rare, and only a few cases have been reported (1, 8,9,10). Therefore, study on the treatment and prognosis of this condition has been limited.…”

In moyamoya disease (MMD), subsequent aneurysm in the proximal part of the posterior communicating artery (PcomA) is extremely rare. We report the case of a middle-aged female patient with MMD, who presented with a ruptured wide-necked aneurysm at the proximal part of the developed PcomA that converged with the posterior cerebral artery (PCA) and supplied the distal area. Endovascular treatment was performed, but the stent-assisted coil embolization resulted in occlusion of the internal carotid artery (ICA) above the ophthalmic artery and PcomA. Due to good compensatory collateral circulation, the patient was improved after surgery and had no complications. One-year followup DSA did not show recurrence of the aneurysm. The right ICA was still embolized, but with good compensatory collateral circulation. We conclude that, for an MMD patient with an aneurysm at the proximal part of the developed PcomA, if the ICA and PcomA are accidentally occluded, then the patient may still have a good prognosis due to sufficient collateral blood circulation.

Moyamoya hastalığı olan ve posterior komünikan arterin proksimal kısmında, posterior serebral arterle birleşip distal bölgeyi besleyen kısımda rüptüre olmuş geniş boyunlu bir anevrizmayla gelen bir hastayı bildiriyoruz. Endovasküler tedavi yapılmış ama stent yardımlı sarmal embolizasyonu oftalmik arter ve posterior komünikan arter üzerinde internal karotid arter oklüzyonuyla sonuçlanmıştır. İyi kompansatuar kollateral dolaşım sayesinde hasta cerrahiden sonra iyileşmiş ve komplikasyon olmamıştır. DSA ile bir yıl sonraki takip, anevrizma nüksü göstermemiştir. Sağ internal karotid arter hala embolize durumdadır ve iyi kompansatuar kollateral dolaşım vardır. Gelişmiş posterior komünikan arterin proksimal kısmında anevrizması olan bir moyamoya hastasında, internal karotid arter ve posterior komünikan arter yanlışlıkla tıkanırsa hastanın yeterli kollateral kan dolaşımı sayesinde hala iyi bir prognozu olabileceğini bildiriyoruz.AnAhtAr sÖZCÜKler: Moyamoya hastalığı, Posterior komünikan arter, Anevrizma
