Ophthalmic Segment Aneurysms

Introduction Ophthalmic segment aneurysms may present with visual symptoms due to direct compression of the optic nerve. Treatment of these aneurysms with the Pipeline embolization device (PED) often results in visual improvement. Flow diversion, however, has also been associated with occlusion of the ophthalmic artery and visual deficits in a small subset of cases. Case report A 49-year-old Caucasian female presented with subarachnoid hemorrhage due to a ruptured anterior communicating artery aneurysm. On follow-up imaging, the patient was found to have a right asymptomatic ophthalmic segment aneurysm. Due to the irregular shape of the aneurysm and history of aneurysmal subarachnoid hemorrhage, the decision was made to treat the aneurysm with a PED. Postoperatively, the patient complained of floaters in the right eye. Detailed ophthalmologic examination showed retinal hemorrhage and cotton-wool spots on the macula. Such complication after PED placement has never been reported in the literature. Conclusion Visual complications after PED placement for treatment of ophthalmic segment aneurysms are rare. It is thought that even in cases where the ophthalmic artery occludes, patients remain asymptomatic due to the rich collateral supply from the external carotid artery branches. Here we report a patient who developed an acute retinal hemorrhage after PED placement.

Abstract A patient presented with spontaneous subarachnoid hemorrhage after a prolonged episode of coughing. A preoperative computed tomographic (CT) scan confirmed subarachnoid hemorrhage, but demonstrated no other lesion. Arteriography revealed an ophthalmic artery aneurysm. Operation revealed the aneurysm to be intracavernous without sign of prior rupture; however, a small hemorrhagic meningioma was removed from the ipsilateral anterior clinoid process. In this case, coincidental meningioma and aneurysm presented as a subarachnoid hemorrhage secondary to tumor hemorrhage. The follow-up of cases of subarachnoid hemorrhage with negative arteriography with sequential CT scans is discussed.

Traumatic Subarachnoid Hemorrhage

Introduction. Vitreous or retinal hemorrhage occurring in association with subarachnoid hemorrhage is known as Terson?s syndrome. In Terson?s syndrome, intracranial hemorrhages are followed by intraocular hemorrhage, classically in the subhyaloid space, but may also include subretinal, retinal, preretinal, and vitreal collections. Vitreous hemorrhage recovery is usually spontaneous in six to 12 months, otherwise vitrectomy is considered. Outline of Cases. We report of two cases of Terson?s syndrome. The first was in a hypertensive middleaged female, following anterior communicating artery aneurismal subarachnoid hemorrhage, after postneurosurgical interventions. The second case report was of a young male who suffered from the bilateral vitreous hemorrhage after a severe traumatic brain injury. Conclusion. Terson?s syndrome should be considered in patients who had previous cerebral hemorrhage and are referred to eye specialist because of loss of vision. However, this phenomenon has only rarely been described in association with subdural and epidural hematomas or traumatic subarachnoid hemorrhage.

Introduction Pericallosal artery (PA) aneurysms represent 2 to 9% of all intracranial aneurysms, and their management remains difficult. Objective The aim of the present study is to describe the case of an adult woman with subarachnoid hemorrhage and bilateral PA aneurysm in mirror position. Case Report A 46-year-old woman was referred to our institution 20 days after a sudden severe headache. She informed that she was treating her arterial hypertension irregularly, and consumed ∼ 20 cigarettes/day. The patient was neurologically intact at admission. A non-contrast computed tomography (CT) on the first day of the onset of the symptoms revealed hydrocephaly and subarachnoid hemorrhage (Fisher III). An angio-CT/digital subtraction arteriography showed bilateral PA aneurysms in mirror position. The patient was successfully treated with surgery via the right interhemispheric approach (because the surgeon is right-handed); the surgeon performed the proximal control with temporary clipping, and introduced an external ventricular drain at the end of the surgery. The patient was discharged on the fourth postoperative day without any additional neurological deficits or ventricular shunts. Conclusion Ruptured PA aneurysm is a surgically challenging aneurysm due to the many anatomical nuances and risk of rebleeding. However, the operative management of ruptured bilateral PA aneurysms is feasible and effective.

Abstract OBJECTIVE AND IMPORTANCE: The present case report is the first one to report a bilateral anastomotic artery between the internal carotid artery and the anterior communicating artery in the presence of a bilateral A1 segment, fenestrated anterior communicating artery (AComA), and associated aneurysm of the AComA, which was discovered by magnetic resonance angiography and treated surgically. CLINICAL PRESENTATION: A 38-year-old man who was previously in good health experienced a sudden onset of nuchal headache, vomiting, and confusion. Computed tomography revealed a subarachnoid hemorrhage. Magnetic resonance angiography and four-vessel angiography documented an aneurysm of the AComA and two anastomotic vessels of common origin with the ophthalmic artery, between the internal carotid artery and AComA. INTERVENTION: A fenestrated clip, introduced by a left pterional craniotomy, leaving in its loop the left A1 segment, sparing the perforating and hypothalamic arteries, excluded the aneurysm. CONCLUSION: The postoperative course was uneventful, with complete recovery. Follow-up angiograms documented the successful exclusion of the aneurysm. Defining this particular internal carotid-anterior cerebral artery anastomosis as an infraoptic anterior cerebral artery is not appropriate because there is already an A1 segment in its habitual localization. Therefore, it is also thought that, embryologically, this anomaly is not a misplaced A1 segment but the persistence of an embryological vessel such as the variation of the primitive prechiasmatic arterial anastomosis. The favorable outcome for our patient suggests that surgical treatment may be appropriate for many patients with this anomaly because it provides a complete and definitive occlusion of the aneurysm.

Abstract INTRODUCTION Subarachnoid hemorrhage has a poor outcome despite a modern advancement in medical care. The development of a novel therapeutic strategy to prevent rupture of intracranial aneurysms (IAs) or a novel diagnostic marker to predict rupture-prone lesions is thus mandatory. Therefore, in the present study, we established a rat model in which IAs spontaneously rupture and examined this model to clarify histopathological features associated with rupture of lesions. METHODS In detail, female Sprague-Dawley rats were subjected to the bilateral ovariectomy, the ligation of the left common carotid, the right external carotid, and the right pterygopalatine arteries, the induced systemic hypertension, and the administration of a lysyl oxidase inhibitor. RESULTS Aneurysmal subarachnoid hemorrhage occurred one-thirds of manipulated animals and locations of ruptured IAs were exclusively at a posterior or an anterior communicating artery. Histopathological examination using ruptured IAs, rupture-prone ones induced at a posterior or an anterior communicating artery, ones induced at an anterior cerebral artery-olfactory artery bifurcation that never rupture revealed the formation of vasa vasorum as an event associated with rupture of IAs. CONCLUSION We thus proposed the contribution of a structural change in an adventitia, vasa vasorum formation, to rupture of IAs. Findings from this study provide important insights about the pathogenesis of IAs.
