Aneurysms arising in the petrous segment of the internal carotid artery (ICA) are rare. Although the causes of petrous ICA aneurysms remain unclear, traumatic, infectious, and congenital origins have been implicated in their development. These lesions can be detected incidentally on routine neuroimaging. Patients can also present with a wide spectrum of signs and symptoms, including cranial nerve palsies, Horner syndrome, pulsatile tinnitus, epistaxis, and otorrhagia. The treatment of petrous ICA aneurysms remains challenging. Treatment options include close observation, endovascular therapies, and surgical trapping with or without revascularization. Management dilemmas exist, particularly for incidental lesions found in asymptomatic patients. The authors review the literature and discuss the anatomy of the petrous ICA as well as the pathophysiological features of aneurysms arising in this region, and they propose a management paradigm with current treatment options.

Abstract: Authors present complex multistage endovascular treatment of female patient with an intradural infiltrative, inoperable tumor of the glomus jugulare, a stenosis of the internal carotid artery and an aneurysm of middle cerebri artery. In the literature our case report is the first announcement in which three pathology coexist ipsilateral in one patient and the patient has been treated step by step by endovascular procedures. Beside the endovascular treatment steps they display glomus jugulare tumor’s symptoms, staging, treatment options and also the current treatment guidelines of internal carotid artery stenosis and intracranial aneurysms.

Aneurysms of the cervical portion of the internal carotid artery are relatively rare and can present difficult diagnostic problems. Signs and symptoms of cerebral ischemia are common, but isolated cranial neuropathies are unusual. A patient with hypoglossal and glossopharyngeal cranial nerve palsies secondary to an extracranial internal carotid artery aneurysm is the subject of this case report and discussion.

Internal Carotid Artery Injury

One of the most serious/potentially fatal complications of transsphenoidal surgery (TSS) is internal carotid artery (ICA) injury. Of 6230 patients who underwent TSS, ICA injury occurred in 8 (0.12%). The etiology, possible treatment options, and avoidance of ICA injury were analyzed. ICA injury occurred at two different stages: (1) during the exposure of the sella floor and dural incision over the sella and cavernous sinus and (2) during the resection of the cavernous sinus extension of the tumor. The angiographic collateral blood supply was categorized as good, sufficient, and nonsufficient to help with the decision making for repairing the injury. ICA occlusion with a balloon was performed at the injury site in two cases, microcoils in two patients, microcoils plus a single barrel extra-intracranial high-flow bypass in one case, stent grafting in one case, and no intervention in two cases. The risk of ICA injury diminishes with better preoperative preparation, intraoperative navigation, and ultrasound dopplerography. Reconstructive surgery for closing the defect and restoring the blood flow to the artery should be assessed depending on the site of the injury and the anatomical features of the ICA.

Cranial Nerve Palsies

Internal carotid dissection most commonly presents as headache, focal neurological deficits or stroke. Rarely it can manifest itself by causing a palsy of the lower cranial nerves (IX, X, XI, XII). The reported incidence of isolated cranial nerve palsies is rare. We report a case of an internal carotid artery dissection manifesting as isolated XII (hypoglossal) cranial nerve palsy.

Thrombosed giant intracranial aneurysms usually present with symptoms and signs from their mass effect. Although multiple treatment options are available, direct clip reconstruction with thromboendarterectomy remains the gold standard. Here we present a 66-year-old man with seizure, aphasia and hemiparesis. Work-up revealed a giant partially thrombosed aneurysm of the internal carotid artery bifurcation with surrounding vasogenic edema. He underwent clip reconstruction of the aneurysm via a cranio-orbital approach. Although we prepared for bypass with the radial artery and/or the superficial temporal artery, we were able to clip-reconstruct the aneurysm without bypass. The patient improved upon his pre-morbid state after surgery and made an excellent recovery.The video can be found here: http://youtu.be/P_10hRQFuPo.

Background: Current debates are focused on inflammatory processes in atherosclerotic lesions as a possible pathomechanism for destabilization and thrombembolism. In this prospective study the role of systemic and local infection in patients with high-grade internal carotid artery stenosis (ICA) was evaluated. Patients and methods: Serum antibody titers of 109 consecutive patients, who underwent surgery for ICA stenosis (asymptomatic n = 40, symptomatic n = 69) were prospectively measured for Chlamydia pneumoniae (Cpn) (IgA and IgG), Herpes simplex virus (HSV) (IgG, IgM) and Cytomegalovirus (CMV) (IgG, IgM) respectively. 53 carotis plaques of this group (asymptomatic n = 17, symptomatic n = 36) could be analyzed by polymerase chain reaction (PCR) for Cpn-, HSV- and CMV-DNA presence. Results: Seropositivity was found in 61,5% for Cpn, 91,7% for HSV and 72,5% CMV respectively. No significant relation was found between symptomatic and asymptomatic patients as well as no difference was seen for presence of IgA antibodies against Cpn comparing both groups. Plaque-PCR revealed Cpn in 7 cases (13,2%), HSV in 2 cases (3,8%) and no CMV had been detected. Again, no significant relationship was found concerning symptomatic and asymptomatic patients. All 9 PCR-positive plaques displayed lesions of "complicated atherosclerosis" as central fibrous necrosis and calcification or plaque bleeding and surface thrombosis. Conclusions: Our results do not support the hypothesis that systemic Cpn, HSV or CMV- infection or evidence of Cpn-, HSV- or CMV-DNA in carotid plaques causes plaque destabilization and cerebral thromboembolism. Plaque infection could only be observed in cases with advanced atherosclerosis.

Recurrent Strokes

Unilateral absence of internal carotid artery (ICA) is a rare congenital anomaly. We present the case of a 35-year-old man with episodes of recurrent strokes in the past and now presenting with right-sided upper limb weakness. Radiological diagnostic workup revealed a thin left ICA in the neck with non-visualization beyond petrous bone in the intracranial course. The ipsilateral brain parenchyma is supplied by vessels from the contralateral side of the Circle of Willis. As the patient had no evidence of a cerebrovascular accident on radiological evaluation and no neurological signs and symptoms, he was discharged with anticoagulant medications with the advice of follow-up. This is the first report to describe a case of ICA agenesis with a pattern of collateral circulation that doesn’t fit any of the six types described by Lie.

Abstract Objective Intracranial aneurysms (AIs) are acquired vascular abnormalities that cause sacculations in the arterial wall and are present in ∼2 to 5% of the population. Among the treatment options are endovascular interventions with the use of flow-redirecting stents. In the present study, we analyzed the flow re-direction endoluminal device (FRED). Methods The present study aims to describe the results obtained from treatment with FRED in a series of patients affected by aneurysms in intracranial segments of the internal carotid artery. This is a cross-sectional, epidemiological, and observational study, whose data were obtained from the medical records of 81 patients from July 2018 to July 2019. Results One hundred and three internal carotid artery aneurysms were observed in 81 patients, with a prevalence of women (91.35%), small (< 10 mm) (89.33%), and located at the C6 level (73.78%) of the internal carotid artery. Of the 81 patients, 16 had multiple aneurysms in the same artery. One hundred and three FRED stents were used in the treatment. These patients underwent angiography 6 months after the surgery, using the O'Kelly-Marotta classification (OKM) to assess the effectiveness of the device, and it was observed that: in 91 of the 103 procedures (88.34%), the FRED was fully open and well positioned, thus restoring the arterial flow and leading to a statistically significant result. In addition, a low complication rate (4.85%) was found, with ischemic stroke being the main complication (1.94%). Conclusion This device can be an effective option in the treatment of internal carotid aneurysms since the aneurysm occlusion rate is excellent with a low rate of complications.
