“…3) There have been many reports on the treatment of PCA aneurysms, but the localization of aneurysms has been classified based on P1-P3, which is the main trunk, and it is unclear how many aneurysms that developed in the PCA temporal branch were included. 3,5) To our knowledge, there has been only one report on the treatment of aneurysms that developed in the PCA temporal branch, 6) and the present case that developed in the peripheral region may be rarer. Two classifications of the 4,7,8) The aneurysm in the present patient was located in the posterior temporal artery in the former classification and PITA in the latter.…”

We report a case of a ruptured aneurysm at the posterior inferior temporal artery (PITA) of the posterior cerebral artery (PCA) treated by intra-aneurysmal coil embolization.Case Presentation: A 93-year-old man presented with disturbance of consciousness. Angiography revealed a 3-mm aneurysm in the distal PITA of the left PCA. He was diagnosed with subarachnoid hemorrhage and intracerebral hemorrhage due to a ruptured aneurysm. This aneurysm was occluded by intra-aneurysmal coil embolization with preservation of the PITA. Conclusion:Distal PITA aneurysm of the PCA is rare. Complete occlusion and preservation of the parent artery were achieved by intra-aneurysmal coil embolization, which may be an effective therapeutic option for such aneurysms.

“…Eighteen patients who underwent treatment for aneurysms of fetal-type PCAs have been reported previously. Of these 18 patients, cerebral infarction occurred in 11 of the 15 patients who had undergone PAO without revasculari- zation, [1][2][3]5,[14][15][16][17] and symptoms were reported in 6 of the 11 cases (Table 1). The remaining 3 patients underwent internal trapping with OA-PCA bypass, which prevented cerebral infarction in 2 cases.…”

BACKGROUND Unlike in aneurysms of the adult-type posterior cerebral artery (PCA), in aneurysms of the fetal-type PCA, parent artery occlusion (PAO) results in vascular insufficiency and major ischemic strokes. Preservation or reconstruction of fetal-type PCAs is necessary to prevent these complications. Furthermore, it is necessary to select an appropriate bypass method and approach for revascularization of the PCA. OBSERVATIONS The authors report 2 cases of aneurysms of fetal-type PCAs that were successfully treated with PAO with revascularization. A 38-year-old man with a large unruptured right PCA aneurysm at the postcommunicating (P2) segment underwent trapping with superficial temporal artery–PCA bypass via the anterior temporal and subtemporal approaches. In addition, a 45-year-old woman with a left PCA aneurysm at the quadrigeminal (P3)–cortical (P4) segments resulting in subarachnoid hemorrhage underwent proximal clipping of the P3 segment via the occipital interhemispheric approach with an occipital artery–PCA bypass. Although she had perforator infarction, major ischemic stroke was prevented, and aneurysm occlusion was accomplished in both cases. LESSONS Aneurysms of fetal-type PCAs pose a risk of ischemia due to PAO. The combined use of bypass and revascularization should be considered to prevent major ischemic stroke after occlusion of the fetal-type PCA. However, perforator infarction is a concern.

“…To our current knowledge, treating methods of AVMs are basing on 3 types [8][9][10][11][12], Arterial Embolization (AE), interventional management and surgical treatment. Previous studies have shown that the potential for the embolization treatment of recanalization of AVMs in other areas, then the follow-up visits confirmed the effective results [13,14].…”

Posterior Cerebral Artery Aneurysms: Treatment and Outcome Analysis in 121 Patients

Abstract: Aneurysms of the PCA are infrequent and often associated with other vascular diseases. Microsurgery and endovascular treatment are effective for the occlusion of PCA aneurysms. The preservation or reconstruction of the parent vessel is crucial for favorable treatment outcomes.
