Conte M, Cagil E, Lanzino G, Keser Z. Fusiform aneurysms of anterior cerebral artery: center experience and systematic literature review. Neurosurg Rev 2023; 47:11. [PMID: 38087068 DOI: 10.1007/s10143-023-02247-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 11/12/2023] [Accepted: 12/05/2023] [Indexed: 12/18/2023]
Abstract
Fusiform aneurysms of the anterior cerebral artery (ACA) are uncommon, and the natural history of this entity is poorly characterized. Along with our center experience, we conducted a systematic literature review to help shed light on the clinical course of ACA fusiform aneurysms. We queried our institutional database to identify cases with fusiform aneurysms of ACA. In addition, following the PRISMA algorithm, we identified all reported cases published in the English literature from the inception of PubMed until December 2022. We categorized clinical presentations into three categories: (i) traumatic/iatrogenic, (ii) spontaneous symptomatic ruptured/unruptured, and (iii) spontaneous asymptomatic aneurysms. We utilized descriptive statistics. We identified seven cases from our center along with 235 patients from published literature. Blunt trauma was responsible for the development of 19 aneurysms. Sixty-three percent of these aneurysms tend to rupture within 2 weeks from the initial trauma, and despite treatment, only 74% of these patients had good clinical outcomes. Spontaneous symptomatic presentation occurred in 207 patients and was often associated with previous/concomitant ACA dissection. Subarachnoid hemorrhage from ruptured aneurysms was the most common presentation. Spontaneous symptomatic fusiform aneurysm is rapidly evolving lesions, and treatment is necessary. Three of our own cases were treated with an endovascular flow diverter (pipeline) stenting with good outcomes. Spontaneous asymptomatic aneurysms were reported in nine patients. These lesions are often associated with other vascular abnormalities. Treatment included surgical clipping with good clinical outcomes. Instead, four patients from our center database were managed conservatively with equally good outcomes. Our study demonstrates good clinical outcomes when fusiform aneurysms of ACA, especially when symptomatic, are treated promptly with either reconstructive or deconstructive therapies.

Simultaneous presentation of subcortical hemorrhage, subdural hemorrhage, and cerebral infarct in a hemiplegic patient. Radiol Case Rep 2022; 17:1376-1379. [PMID: 35251421 PMCID: PMC8892005 DOI: 10.1016/j.radcr.2022.02.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 01/31/2022] [Accepted: 02/02/2022] [Indexed: 11/20/2022] Open
Abstract
A 90-year-old, non-hypertensive woman presented gait disturbance followed by falls. She had developed a lacunar infarction in the right frontal lobe 1 month previously that subsequently resulted in subtle motor weakness in the left lower extremity. At presentation, the patient showed motor weakness in the left upper and lower extremities with normal findings on blood test. Cranial computed tomography (CT) revealed a subcortical hemorrhage in the anterior part of the right frontal lobe that was accompanied by perilesional edema. In addition, two small subdural hematomas, apparently in the acute phase, were found. Magnetic resonance imaging performed immediately after the CT revealed hyperacute infarct in the right precentral gyrus adjacent to the previous infarct. It was hyperintense on the diffusion-weighted imaging but indistinct on the fluid-attenuated inversion recovery sequence. In addition, findings suggesting cerebral contusions were not observed. Based on these, we assumed that the patient's symptoms were mainly derived from the infarct and the subdural hemorrhages had developed in association with falls. However, it was unclear whether the infarct had developed before or after the formation of subcortical hemorrhage. Traumatic and non-traumatic intracranial hemorrhage and cerebral infarcts may present simultaneously. When intracranial hemorrhages appearing on CT do not adequately explain the patient's neurological findings, undetected cerebral ischemia should be assumed.

Abstract
BACKGROUND Fusiform aneurysms (FA) of the anterior cerebral artery (ACA) are found rarely. The common clinical presentation is a subarachnoid hemorrhage (SAH). Surgery is the main treatment to prevent rebleeding. CASE DESCRIPTION The authors present a case report of the ruptured FA of the ACA. The presented case demonstrates the successful microsurgical clipping of the fusiform ACA aneurysm. CONCLUSION A1-segment FA can lead to SAH with poor prognosis. The main goal of surgical treatment is to prevent rebleeding. Direct microsurgical clipping is one of the surgical options.

Abstract
Objective To report a case of ruptured anterior cerebral artery dissection treated with stent-assisted coil embolization with overlapping stents. Case Presentation A 51-year-old woman developed subarachnoid hemorrhage the day after transient left hemiparesis. Angiography revealed a ruptured anterior cerebral artery dissecting aneurysm. We conducted stent-assisted coil embolization with the overlapping stent technique on the day after the hemorrhage. She recovered steadily without rebleeding. Six months after embolization, no recurrence was found on angiography. Conclusion Although an acceptable result was achieved in this case, the safety and efficacy of this procedure are unconfirmed. A larger number of cases should be accumulated.

Abstract
The present report describes the case of a 57-year-old woman presenting with subarachnoid hemorrhage (SAH) and acute ischemic stroke (AIS) due to anterior cerebral artery (ACA) dissection, which exhibited severe stenosis at the origin with distal dilatation of the A2 segment and occlusion of the A3 segment. In this case, computed tomography (CT) revealed SAH in right superior frontal sulcus and the interhemispheric fissure. Magnetic resonance imaging demonstrated acute infarct in the territory of the right ACA. Brain digital subtraction angiography showed severe stenosis at the origin of the A2 segment with distal dilatation and occlusion at the origin of the A3 segment of the right ACA, suggesting a diagnosis of dissection. Only treatment with atorvastatin, her clinical condition subsequently improved. The stenosis and dilatation of A2 segment were ameliorated as demonstrated by a follow-up CT angiography 5 months after onset. SAH concomitant with ischemia caused by ACA dissection is rare. Conservative treatment may be a safe and effective choice for patients with SAH concomitant with AIS due to ACA dissection.

Abstract
Dissecting aneurysms in the anterior cerebral artery (ACA), although rare, can cause ischemic and/or hemorrhagic stroke. Hemorrhagic dissecting aneurysms in the A1 portion of the ACA are often associated with a poor prognosis. We retrospectively investigated three rare cases of hemorrhagic dissecting aneurysms in the A1 portion. Dissecting aneurysms were diagnosed by carotid angiography or computed tomography angiography to visualize morphological changes in the vessel. All patients presented with diffuse subarachnoid hemorrhage. In one case, computed tomography angiography performed at the onset of the subarachnoid hemorrhage revealed fusiform dilatation at the right ACA (A1), which did not appear on a magnetic resonance angiogram obtained 1 year prior to the onset of the subarachnoid hemorrhage. In the other two cases, A1 dissecting aneurysms were diagnosed from a growing aneurysmal bulge revealed at a non-bifurcated site via repeated carotid angiography. Two patients underwent surgical intervention (trapping or clipping), and their outcome was favorable, whereas the third patient died of delayed rebleeding before receiving surgical treatment. Hemorrhagic dissecting aneurysms in the A1 portion cause severe subarachnoid hemorrhage. Surgical treatments that include revascularization are necessary to prevent rebleeding, and direct surgery is recommended, particularly at the A1 portion.

Abstract
A basilar artery dissection (BAD) is an extremely rare disease. It can lead to hemorrhage or infarction involving the brain stem, and is often associated with grave outcome. However, little is known about the pathophysiology of BAD, and its proper managements are yet in controversy. Herein, we report on two rare cases of basilar artery dissection from strenuous physical effort; one from sexual intercourse and another from defecation. The treatment modalities and the outcomes are also discussed.

Abstract
BACKGROUND Compared to those found in the vertebrobasilar system, intracranial dissection in the anterior circulation is relatively rare, especially in the anterior cerebral artery (ACA). Moreover, only several cases of ACA dissection that underwent endovascular treatment have been reported. Here we present a rare case of gradually developing ACA dissecting aneurysm causing cerebral infarction, successfully treated by stent-assisted coil embolization. CASE DESCRIPTION A 36-year-old man was admitted with sudden right hemiparesis. Diffusion-weighted magnetic resonance (MR) imaging showed cerebral infarction in the left ACA territory, and MR angiography showed segmental stenosis at the A2 portion of the left ACA. Three-dimensional digital subtraction angiogram showed segmental dilatation and stenosis at the left A2 portion. We diagnosed ACA dissection causing acute cerebral infarction and treated the patient conservatively. Five months after the onset, the dissecting artery at the left A2 portion formed a gradually dilating aneurysm, suggesting increased risk for aneurysmal rupture. We attempted endovascular treatment entailing coil embolization of an aneurysm while preserving the left A2 with stent assistance. The patient remained neurologically stable 6 months after the procedure. CONCLUSIONS Although there are few reported cases of ACA dissection where endovascular treatment was attempted, we consider stent-assisted embolization for gradually developing ACA dissecting aneurysm as an alternative method to prevent bleeding and recurrent infarction.

Abstract
Spontaneous anterior cerebral artery (ACA) dissection, although extremely rare, is often associated with severe morbidity and mortality. It could lead to cerebral hemorrhage, ischemic stroke, or, rarely, combination of hemorrhage and ischemia due to hemodynamic changes. Prompt and accurate diagnosis is essential for determining the appropriate management. However, the optimal treatment for ACA dissection remains controversial. Herein, we report on two rare cases of subarachnoid hemorrhage (SAH) caused by ACA dissection; a case presenting with simultaneous SAH and infarction without aneurysmal formation and another case presenting with SAH with fusiform aneurysmal formation. A review of the related literature is provided, and optimal treatments for each type of dissection are suggested.

Abstract
A 46-year-old man presented with right hemiparesis. Cranial magnetic resonance (MR) imaging revealed both an acute cerebral infarction in the territory of the left anterior cerebral artery (ACA) and a thin subarachnoid hemorrhage in the left superior frontal sulcus. MR angiography revealed stenosis at the A2 segment of the left ACA. MR cisternography was, therefore, performed on day 12 after admission using sagittal, 3-dimensional, heavily T2-weighted images. Fusiform dilatation of the outer contour was confirmed by MR cisternography at the region of narrowing identified by MR angiography. This case indicates that the combination of MR cisternography and angiography can be useful for detecting ACA dissection.

Abstract
Simultaneous subarachnoid hemorrhage and infarction is a quite rare presentation in a patient with a spontaneous dissecting aneurysm of the anterior cerebral artery. Identifying relevant radiographic features and serial angiographic surveillance as well as mode of clinical manifestation, either hemorrhage or infarction, could sufficiently determine appropriate treatment. Enlargement of ruptured aneurysm and progressing arterial stenosis around the aneurysm indicates impending risk of subsequent stroke. In this setting, prompt treatment with stent-assisted endovascular embolization can be a reliable alternative to direct surgery. When multiple arterial dissections are coexistent, management strategy often became complicated. However, satisfactory clinical results can be obtained by acknowledging responsible arterial site with careful radiographic inspection and antiplatelet medication.
