A 73-year-old woman was referred to our Cardiology Department due to recurrent headaches and dizziness. She had a history of hypertension of 10 years. In the territorial hospital, left internal carotid artery significant stenosis was suspected. Neurological examination and laboratory tests were normal. A neck vascular ultrasound was performed, showing a low bifurcation of the left common carotid artery (CCA) and a hypoplastic left internal carotid artery (ICA) with a sinuous path at the cervical level. Therefore, a computed tomographic (CT) angiography examination of the head and neck vessels was performed. The images confirmed the presence of a hypoplastic left ICA, anatomic variation in the left CCA, and also showed that the left vertebral artery (VA) was stemming directly from the aortic arch, exhibiting a kinking trajectory.

Abstract: This chapter presents a case of a man with a history of previous subarachnoid hemorrhage from a ruptured basilar tip aneurysm and incidentally noted small, left, internal carotid artery bifurcation aneurysm that was unruptured. Preoperative assessment and decision-making for treatment are discussed for an unruptured aneurysm in the context of risk factors for hemorrhage, which varies by location. Relative indications for endovascular compared to open surgical treatment are presented, as well as comparative results of treatment with the different modalities. Procedure-related complications and management are also outlined. The presence of a large number of critical perforators around internal carotid artery terminus aneurysm that must be preserved presents a special risk of this aneurysm type, that must be considered for either open or endovascular treatment.

A 53-year-old healthy man with history of left internal carotid artery dissection in 2006 presented with right-sided facial pain with paraesthesia associated with taste and speech disturbances. A CT angiogram was done without further delay considering the patient’s history of dissection, and revealed a non-occlusive right-sided internal carotid artery dissection at the skull base level. The neurologist, neurosurgeons and stroke team were involved in the care, and the patient was immediately moved to a tertiary hospital for further intervention. Brain MRI and magnetic resonance angiography did not reveal further progression of the dissection and the patient was therefore medically managed.

Abstract A 28-year-old woman with von Recklinghausen's neurofibromatosis (NF-1) had a huge hematoma in the left posterior nuchal region. Carotid and vertebral angiograms revealed marked stenosis at the C3 portion of the left internal carotid artery, slight moyamoya staining, occlusion of the left vertebral artery at the atlas level, and a right internal carotid artery aneurysm. The radiographic, clinical, and histological features of this case are discussed together with a review of 42 similar cases found in the literature. (Neurosurgery 22:544-549, 1988)

A 79-year-old male patient who presented with dizziness and several syncopal episodes was admitted to our clinic. Medical history of the patient revealed arterial hypertension and multifocal atherosclerosis with a history of two ischemic left middle cerebral artery strokes within the last year, without residual deficits, two coronary artery bypass grafts 22 years ago, and Stage IIB peripheral artery disease. The imaging studies revealed severe stenosis of the left internal carotid artery and high-grade ostial stenosis of the left common carotid artery. After clamping of the internal carotid artery and endarterectomy with patch angioplasty, before the patch was completely sutured, a sheath was placed through it and dilation and retrograde stenting of the proximal segment of the left common carotid artery were performed. The neurological symptoms of the patient disappeared and on postoperative computed tomography angiography, there was no residual carotid stenosis.

Giant intra and parasellar aneurysm with a spontaneous thrombosis of internal carotid artery is rare. We report the case of a 34 years old woman presenting a unique giant sellar and parasellar aneurysm associated with hypopituitarism and amenorrhea-galactorrhea syndrome. Computed tomographic scans and magnetic resonance images were suggestive of a sellar tumor with a cystic component. Digital cerebral angiography showed spontaneous thrombosis of a intrasellar and parasellar carotid artery aneurysm and left internal carotid artery in the neck. A transseptal endoscopic biopsy was done and confirmed a thrombosed aneurysm. No other surgical treatment was required in this patient but permanent endocrinological treatment was necessary.

Agenesis of the internal carotid artery (ICA) is a rare congenital anomaly. Most of the patients are asymptomatic and it is usually discovered incidentally by computed tomography (CT) or magnetic resonance imaging (MRI). There is close association of the cranial aneurysms and subarachnoid hemorrhage with ICA agenesis. We present a case of a 61-year-old male with left ICA agenesis associated with basilar artery and left vertebral artery aneurysms. The patient complained of headaches and numbness on the right-side of the face. Physical examination showed high blood pressure (210/90 mmHg). Neurological examination revealed nystagmus and decreased sensation on the right-side of the face. Agenesis of left ICA, left carotid canal with basilar and left vertebral artery aneurysms were demonstrated incidentally using CT, MRI, and digital subtraction angiography, as a part of an evaluation for suspected cerebrovascular accident.

Infectious pseudoaneurysm is a rare condition characterized by arterial wall dilation, usually due to an adjacent infectious focus. We present an 8-year-old male with a 3-day history of progressive, severe headache 2 weeks after treatment for a parapharyngeal abscess. Computed tomography revealed a left internal carotid artery (ICA) pseudoaneurysm inferior to the skull base and a small parapharyngeal abscess inferior to the pseudoaneurysm. The patient was admitted for intravenous antibiotic treatment and underwent transfemoral endovascular coil occlusion of the cervical ICA pseudoaneurysm without complications. We discuss the presentation and management of rare vascular complications of parapharyngeal abscesses involving major arteries of the neck and the role of neurointerventional embolization in these cases.

Internal carotid artery pseudoaneurysm is a rare complication of deep neck infections. The authors report the case of a 17-year-old male who presented to the Department of Otorhinolaryngology with an acute tonsillitis requiring tonsillectomy. Four weeks after the surgery the patient was readmitted because of progressive swallowing, trismus, and worsening headache. Computed tomography revealed a pseudoaneurysm of the left internal carotid artery in the extracranial segment. A bare Wallstent was implanted primarily and a complete occlusion of the pseudoaneurysm was achieved. The endovascular approach is a quick and safe method for the treatment of a pseudoaneurysm of the internal carotid artery.

OBJECTIVEThere are little data in the literature on the characteristics and natural history of unruptured intracranial aneurysms in children. The authors analyzed their experience with unruptured intracranial aneurysms in the pediatric population at their tertiary care pediatric institution over the last 18 years. The first objective was to assess the imaging characteristics and natural history of these aneurysms in order to help guide management strategies in the future. A second objective was to evaluate the frequency of an underlying condition when an incidental intracranial aneurysm was detected in a child.METHODSThe authors conducted a Research Ethics Board–approved retrospective review of incidental intracranial aneurysms in patients younger than 18 years of age who had been treated at their institution in the period from 1998 to 2016. Clinical (age, sex, syndrome) and radiological (aneurysm location, type, size, thrombus, mass effect) data were recorded. Follow-up imaging was assessed for temporal changes.RESULTSSixty intracranial aneurysms occurred in 51 patients (36 males, 15 females) with a mean age of 10.5 ± 0.5 years (range 9 months–17 years). Forty-five patients (88.2%) had a single aneurysm, while 2 and 3 aneurysms were found in 3 patients each (5.8%). Syndromic association was found in 22 patients (43.1%), most frequently sickle cell disease (10/22 [45.5%]). Aneurysms were saccular in 43 cases (71.7%; mean size 5.0 ± 5.7 mm) and fusiform in the remaining 17 (28.3%; mean size 6.5 ± 2.7 mm). Thirty-one aneurysms (51.7%) arose from the internal carotid artery (right/left 1.4), most commonly in the cavernous segment (10/31 [32.3%]). Mean size change over the entire follow-up of 109 patient-years was a decrease of 0.6 ± 4.2 mm (range −30.0 to +4.0 mm, rate −0.12 ± 9.9 mm/yr). Interval growth (2.0 ± 1.0 mm) was seen in 8 aneurysms (13.3%; 4 saccular, 4 fusiform). An interval decrease in size (8.3 ± 10.7 mm) was seen in 6 aneurysms (10%). There was an inverse relationship between aneurysm size and growth rate (r = −0.82, p < 0.00001). One aneurysm was treated endovascularly with internal carotid artery sacrifice.CONCLUSIONSUnruptured pediatric intracranial aneurysms are most frequently single but can occur in multiples in a syndromic setting. None of the cases from the study period showed clinical or imaging signs of rupture. Growth over time, although unusual and slow, can occur in a proportion of these patients, who should be identified for short-term imaging surveillance.
