BACKGROUND AND PURPOSE: Tandem aneurysms are defined as multiple aneurysms located in close proximity on the same parent vessel. Endovascular treatment of these aneurysms has rarely been reported. Our aim was to evaluate the safety and efficacy of a single Pipeline Embolization Device for the treatment of tandem aneurysms of the internal carotid artery. MATERIALS AND METHODS: A retrospective analysis of consecutive aneurysms treated with the Pipeline Embolization Device between 2009 and 2016 at 3 institutions in the United States was performed...

An 8-month old female presented with spontaneous subarachnoid hemorrhage and was treated successfully with endovascular coil embolization of the ruptured aneurysm. Transcranial Doppler ultrasound performed four days later demonstrated middle cerebral artery (MCA) velocities greater than 350 cm/sec on the right and greater than 200 cm/sec on the left, despite medical management. The patient demonstrated no focal neurological deficits, though examination was limited by our patient's sedation and intubation. Angiography revealed severe vasospasm of the supraclinoid internal carotid and MCA territories, bilaterally...

Segmental arterial mediolysis (SAM) is a non-atherosclerotic, non-hereditary vasculopathy that most commonly involves abdominal aortic branches and predominantly affects middle-age and elderly populations. Lysis of the outer arterial media results in separation of the media from the adventitia leading to dissecting aneurysms and/or pseudoaneurysms. We report a unique case of a 47-year-old man who presented with bilateral internal carotid artery dissection followed by dissections and aneurysms involving multiple visceral arteries...

A giant intracranial internal carotid artery(ICA)aneurysm is difficult to treat. We encountered a case with an unruptured giant intracranial ICA aneurysm with a ruptured C2 aneurysm of the ipsilateral ICA. In this case report, we describe how the treatment and review the literature. A 59-year-old man presented with sudden-onset headache and vomiting. He was diagnosed at a local neurosurgical unit as having a subarachnoid hemorrhage and admitted to our hospital. Cerebral angiogram revealed an unruptured giant ICA C3-4 aneurysm with a ruptured aneurysm of the ipsilateral ICA C2...

Duplication of the middle cerebral artery(MCA)is an anatomical variant of the MCA, originating from the distal portion of the internal carotid artery(ICA)and supplying blood flow to the tip of the temporal lobe. Cerebral aneurysms rarely develop at the bifurcation of the ICA and the duplicated MCA, but when they do develop, they may result in subarachnoid hemorrhage. We treated a 41-year-old man, who was urgently brought to our hospital because of severe headache. A computed tomography(CT)scan showed subarachnoid hemorrhage due to the rupture of an aneurysm at the origin of the duplicated MCA...

We conducted a prospective study to analyze the medially displaced courses of the common carotid artery (CCA) and the cervical segment of the internal carotid artery (ICA) in patients who were diagnosed with a pulsatile mass on nasopharyngolaryngoscopy and by clinicoradiologic findings. Our study group was made up of 62 patients-40 women and 22 men, aged 30 to 88 years (mean: 63.7)-who presented with a submucosal pseudomass or a bulging mass on the pharyngeal wall with obvious pulsation. For comparison purposes, we recruited a control group of 62 consecutively presenting patients who had been admitted to our Neurology Department with acute severe headache and who had undergone CT angiography based on a suspicion of an aneurysm or a vertebral or carotid artery dissection...

BACKGROUND: Superior hypophyseal artery (SHA) aneurysms form a unique subgroup of paraclinoid aneurysms having a propensity to grow to a large size in the suprasellar region resulting in compression of the optic nerve, chiasma, and/or tract. AIM: A new classification of SHA aneurysms is proposed that helps in identifying the surgical issues encountered during surgical clipping of these medially directed aneurysms located at different segments of the medial surface of the internal carotid artery (ICA)...

Introduction Blunt head trauma can injure the cavernous segment of the internal carotid artery (ICA). This may result in a carotid cavernous fistula (CCF). Rarely, a traumatic aneurysm may bleed medially causing massive epistaxis. Case presentation We present two cases of traumatic intracavernous carotid pseudoaneurysms with delayed massive epistaxis. The patients were managed with endovascular treatment involving coil embolization with parent vessel sparing and detachable balloon occlusion with carotid sacrifice...

Congenital cyanotic heart disease can lead to intra-cranial involvement. Authors report a very rare case of right intra-cerebral abscess diagnosed on computerized tomography (CT) scan and simultaneous presence of an aneurysm of the left internal carotid artery diagnosed on CT angiogram in a 15-year-old child with congenital cyanotic heart disease with recent onset left hemiparesis. Right cerebral abscess was tapped and left internal carotid aneurysm was planned to be followed up by giving antibiotics and serial angiograms, but he could not survive and died due to non-cranial cause...

BACKGROUND: Intracranial pseudoaneurysms are rare vascular defects of arterial walls that are classically the result of traumatic injury, iatrogenic causes, or infection. Idiopathic pseudoaneurysms are seen even less frequently and are often related to atherosclerosis. Pseudoaneurysms are most commonly found along the distal wall of the internal carotid artery, however, can occur at any location in the cerebrovascular circulation. Treatment of these arterial defects is often challenging due to their frail nature...

OBJECTIVE: Pipeline Embolization Devices (PED) are commonly used for endovascular treatment of cerebral aneurysms but can be associated with delayed ipsilateral intraparenchymal hemorrhage (DIPH). The role that altered intracranial hemodynamics may play in the pathophysiology of DIPH is poorly understood. We assess middle cerebral artery (MCA) flow velocity changes after PED deployment. MATERIALS AND METHODS: Patients with aneurysms located proximal to the internal carotid artery terminus treated with PED at our institution between 2015 and 2016 were retrospectively reviewed...

The efficacy of mechanical thrombectomy with stent retrievers for emergent large vessel occlusion has been proved by randomized trials. Mechanical thrombectomy is increasingly being adopted in Japan since stent retrievers were first approved in 2014. An urgent clinical task is to offer structured systems of care to provide this treatment in a timely fashion to all patients with emergent large vessel occlusion. Treatment with flow-diverting stents is currently a preferred treatment option worldwide for large and giant unruptured aneurysms...

OBJECTIVE: Large internal carotid artery aneurysms can cause remodeling of the sphenoid bone with subsequent hemorrhage into the sinus. No reports have demonstrated small unruptured lesions causing similar bone remodeling. The purpose of this study was to demonstrate our experience with small unruptured paraophthalmic aneurysms causing sphenoid bone remodeling, specifically when the optimal aneurysm inflow angle is present. METHODS: We searched our database for computed tomography angiography studies of small paraophthalmic aneurysms and assessed adjacent sphenoid bone remodeling and inflow angle...

Large cerebral aneurysms are considered more dangerous than their smaller counterparts, with higher risk of subarachnoid hemorrhage. Understanding the hemodynamics of large aneurysms has potential to predict their response to treatment. Digital subtraction angiography images for patients with intracranial aneurysms over a seven-year period were reviewed. Unruptured solitary aneurysms of the internal carotid artery (ICA) proximal to the terminus and posterior communicating artery were included. Contrast intensity over time was analyzed at the center of the M1 segment of the middle cerebral artery distal to the aneurysm and compared to the contralateral side...
