BACKGROUND: The association between glioblastoma and intracranial aneurysm is rare. Treatment guidelines do not exist, and operative mortality and morbidity are significantly high. To our knowledge, no prior cases have employed endovascular therapy for the treatment of these intra-tumor intracranial aneurysms followed by tumor resection. CASE PRESENTATION: A 74-year-old male, history of a left A2 aneurysm, presented after a motor vehicle accident at low speeds. Imaging was concerning for a possible traumatic brain contusion, an aneurysmal hemorrhage given history of left A2 aneurysm, or a hemorrhage from an underlying tumor given profound edema...

Traumatic intracranial aneurysms (AICT) are rare and are associated with high morbidity and mortality. AICT are the result of head injuries caused by accidents, explosions, and gunfire. The case is reported here of a 28 year old man who was admitted to our hospital after suffering a penetrating head injury caused by a bullet. Radiographic studies showed interhemispheric subarachnoid haemorrhage and a likely AICT image that initially went unnoticed. One week later he underwent a cerebral angiography which showed a bilateral vasospasm of the terminal portion of the internal carotid and the appearance of a 2mm fusiform AICT at the orbit-frontal branch of the anterior cerebral artery...

Subarachnoid hemorrhage (SAH) following aneurysm bleeding accounts for 6% to 8% of all cerebrovascular accidents. Although an aneurysm can be effectively managed by surgery or endovascular therapy, delayed cerebral ischemia is diagnosed in a high percentage of patients resulting in significant morbidity and mortality. Cerebral vasospasm occurs in more than half of all patients after aneurysm rupture and is recognized as the leading cause of delayed cerebral ischemia after SAH. Hemodynamic strategies and endovascular procedures may be considered for the treatment of cerebral vasospasm...

OBJECTIVE AND IMPORTANCE: Traumatic intracranial aneurysms present diagnostic and therapeutic challenges. Owing to their fragile nature, endovascular intervention has become the first-line treatment; however, direct surgery has an advantage in certain cases. CLINICAL PRESENTATION: A 34-year-old man in coma was admitted after a motor vehicle accident. Brain computed tomographic scans revealed deep bifrontal, left intraventricular, and subarachnoid hemorrhages. Three-dimensional computed tomographic angiography and digital subtraction angiography revealed an aneurysm arising from the left pericallosal artery...

An aberrant left subclavian artery is a rare variant that has been reported to coexist with the right-sided aortic arch in many cases. We encountered a case in which percutaneous transluminal angioplasty using a stent was performed for an aberrant left subclavian artery and left carotid artery. The patient was a 63-year-old man in whom left carotid artery stenosis and abnormal flow pattern of the left vertebral artery was accidently found during an ultrasound screening of his carotid artery. The right-sided aortic arch with the aberrant left subclavian artery was revealed by a cerebral angiogram via the right femoral artery...

Innovations in endovascular tools have permitted an increasingly broad range of neurovascular lesions to be treated via minimally invasive methods. However, some device modifications may carry additional risks, not immediately apparent to operators. A patient with a symptomatic, partially thrombosed basilar apex aneurysm was allocated balloon-assisted coiling. Attempts were made to place a microwire across the basilar apex through the posterior communicating artery. Overlapping courses of the posterior cerebral and posterior choroidal arteries on the roadmap images were not recognized and a flanged-tip microwire was inadvertently advanced deep into the choroidal artery...

A 7-month-old baby presented with a 4-day history of drowsiness and vomiting after a falling accident. Magnetic resonance imaging demonstrated diffuse subarachnoid hemorrhage, intraventricular hemorrhage, and variable stages of subdural hematoma in bilateral occipital and left temporal subdural spaces. A partially thrombosed aneurysm was noted in the right craniocervical junction. Ophthalmological examination revealed bilateral retinal petechial hemorrhages. Conventional cerebral angiography revealed a dissecting aneurysm in the right posterior inferior cerebellar artery (PICA)...

Sixty-five middle cerebral artery (MCA) aneurysms in 59 patients treated by endovascular treatment (EVT) without the remodelling technique were analyzed. For ruptured aneurysms, the patients in bad condition are predominant and those with Fisher group four is 47.8% and with Hunt and Hess grade (HHG) IV or V are 43.5%. The clinical result is that 58.7% is in mRS 0-3, 21.7% in 4-5 and 19.6% in death. Contrary, 92.3% of the patients in HHG I-III resulted in mRS 0-3. Re-rupture was observed in two cases (4.4%)...

Stroke is the third leading cause of death in the United States. Intracranial atherosclerotic disease plays a role in cerebrovascular accidents, with well-characterized modifiable and nonmodifiable risk factors. Surgical bypass has so far not proved to be superior to medical therapy. Both medical and endovascular therapies for intracranial atherosclerosis have evolved since the initial off-label use of cardiac devices for its treatment. Initial reports on the results of stent placement for symptomatic high-grade intracranial atherosclerotic disease were initially encouraging...

HydroCoils are platinum helical coils coated with a layer of hydrophilic acrylic polymer (hydrogel), which on contact with blood causes disentanglement of polymer chains and expansion. We retrospectively reviewed a series of 29 patients harboring 29 cerebral aneurysms treated with the Hydrocoil Embolic System in the period 2004-2005, discussing the results of endovascular procedures in terms of safety and efficacy. The immediate post-procedure angiographic control demonstrated complete aneurysm occlusion in 21 cases (72...

A carotid-cavernous fistula is a life-threatening condition characterised by an abnormal communication between the carotid arterial vessels and the cavernous venous system. Although these fistulae can arise spontaneously, they mainly occur after trauma, especially road traffic accidents, falls and penetrating cranial or orbital injuries. The mainstay of treatment involves endovascular embolization, but in those patients where this is not possible or where embolization fails, direct surgical intervention and ligation of the artery may be necessary...

Traumatic pericallosal artery aneurysms are rare complications of blunt head trauma. The pericallosal artery is torn under the sharp edge of the rigid falx. CT shows a typical hematoma in the corpus callosum. Endovascular treatment with occlusion of the aneurysm including the parent vessel with coils or glue is the best treatment option.
