Cervical Internal Carotid Artery

Introduction : C‐Guard carotid stent is a self‐expandable open cell stent covered with a double‐layer mesh which was developed for the treatment of internal carotid artery disease. Lower procedural and complications rates, as well as lower post‐operative infarctions are some advantages of this device. Nevertheless, the use of C‐Guard in the treatment of cervical internal carotid artery (ICA) aneurysms is scarce. Therefore, we present two cases in which the C‐Guard stent achieved complete angiographic occlusion at follow‐up. Methods : We identified two cases in which the C‐Guard carotid stent was used to treat symptomatic cervical ICA aneurysms. Angiographic follow‐up was performed. Results : Case 1: 47‐yo female presented left‐sided motor deficit. CT showed ischemic areas in the right hemisphere and CTA demonstrated an unruptured aneurysm in the C1 segment of the right ICA. The patient started dual antiplatelet therapy (DAPT) with aspirin and clopidogrel. A 6mm x 40 mm C‐Guard carotid stent was deployed without complications. One‐year follow‐up CTA showed complete obliteration of the aneurysm with reconstruction of the ICA. Case 2: 38‐yo male presented decreased left visual acuity. CTA and DSA showed an unruptured aneurysm in the C1 segment of the ICA. The patient started DAPT with aspirin and clopidogrel. A 7mm x 30 mm C‐Guard carotid stent was deployed without complications. Three‐month follow‐up DSA showed complete obliteration of the aneurysm with adequate filling of distal vessels. Conclusions : C‐Guard stent is a potential alternative to conventional carotid stents in the treatment of cervical ICA aneurysms with high obliteration rates at follow‐up.

Cervical Internal Carotid Artery

Background: Cervical internal carotid artery (ICA) tortuosity has been associated with vascular risk and stroke as well as genetic disorders related to abnormal extracellular matrix remodeling. It is plausible that dystrophic or aberrant arterial remodeling may therefore relate to cervical ICA tortuosity. We hypothesized that cervical ICA tortuosity relates to carotid dilatation, but not to traditional ultrasound (US) markers of atherosclerosis. Methods: Subjects of the NOMAS with available time-of-flight MRA were included in our study. Cervical ICA tortuosity was defined as a bend in the distal cervical ICA of > 90° as seen on MRA. We excluded subjects with < 5 cm of the cervical ICA visualized. Distensibility was calculated as the percentage excursion of the right CCA diastolic diameter during systole, which was assessed by high-resolution B-mode US of the right common carotid artery (CCA). We used multivariable logistic regression analyses to estimate odds ratios for the association of cervical ICA tortuosity and Doppler measures of carotid wall aging. Results: We visualized cervical ICA tortuosity in 468 NOMAS participants (mean age 64±8 years, 70% women, 70% Hispanic). It was present in 23% of subjects. In unadjusted models, cervical ICA tortuosity was more common in women (OR 2.34, 95% CI 1.34-4.11), Hispanics (OR 1.85, 95%CI 1.06-3.25) and those with higher diastolic blood pressures (OR per mm Hg 1.04, 95%CI 1.01-1.06), and less common among smokers (OR 0.23, 95%CI 0.07-0.78). In models adjusted for demographic and vascular risks, right CCA tortuosity was associated with ipsilateral larger CCA DD (OR 1.42, 95%CI 1.02-1.96) and borderline associated with lower distensibility (OR 0.94, 95%CI 0.87-1.01, P=0.06) but not with ipsilateral ICA IMT (OR 0.26, 95%CI 0.14-4.77), number of plaques (OR 1.08, 95%CI 0.76-1.53), maximum plaque thickness (OR 0.96, 95%CI 0.73-1.27), or plaque area (1.00, 95%CI 0.97-1.05). Conclusions: Cervical ICA tortuosity associates with ipsilateral cervical ICA dilatation and lower distensibility, but not with traditional US markers of atherosclerosis. The association with diastolic blood pressure suggests a role of steady, rather than pulsatile, hemodynamics in aberrant cervical ICA remodeling.

Abstract Objective The management of intraluminal carotid thrombus is not well defined. Medical and surgical management carry a relatively high risk of thromboembolism. Although endovascular options also carry the risk of thromboembolism from manipulation of the lesion, successful carotid stent placement using various methods of flow restriction has been reported anecdotally. We describe a technique to arrest antegrade flow before placement of carotid stents in the setting of symptomatic intraluminal thrombus. Clinical Presentation A 49-year-old woman presented with expressive dysphasia, right-upper extremity weakness, and an episode of left monocular blindness. Angiography confirmed the presence of a large intraluminal thrombus in a chronic dissection of the left internal carotid artery. Results We devised a configuration to arrest antegrade flow in the internal carotid artery before crossing the thrombus with a distal embolic protection device by inflating balloons in the common carotid artery and external carotid artery before crossing the lesion. After inflation of a balloon in the internal carotid artery, we completed overlapping stent placement to completely exclude the thrombus from the lumen. Conclusion The patient remained neurologically unchanged during and immediately after the procedure. She had mild neurological deficits at the 1 month follow-up evaluation. Follow-up ultrasonography at 1 and 3 months and computed tomographic angiography at 3 months after the procedure showed patency of the stented carotid artery, with no evidence of restenosis or thrombus. Although the risks of carotid stent placement for intraluminal thrombus remain unclear, the technique of flow arrest seems to provide a safe endovascular treatment option.

This case illustrates the usefulness of an endovascular stent to treat a pseudoaneurysm of the cervical internal carotid artery. A 46-year-old male patient presented with a spontaneous dissection of the cervical internal carotid artery. After failing conservative therapy, he was treated by endovascular placement of a Palmaz stent at level of the pseudoaneurysm and dissection. Immediate obliteration of pseudoaneurysm was achieved, and patency of the internal carotid artery was maintained. The patient sustained no neurological complications and the stenosis of treated carotid artery did not occur during the 6-month follow-up period. For internal carotid artery dissection, stent placement seems to be a reasonable therapeutic alternative to direct surgery.

Cervical Internal Carotid Artery

Percutaneous transluminal angioplasty (PTA) for severe arteriosclerotic stenosis in the cervical internal carotid artery (ICA) was successfully carried out in 23 cases between December 1994 and August 1996. In order to analyze the condition of the cervical ICA in the early stage after PTA, 12 stenotic lesions of 11 cases were exposed to follow-up study of stenotic cervical ICA after PTA with magnetic resonance angiography (MRA) 1 to 150 days postoperatively. In six lesions, the diameter of the cervical ICA was dilated sequentially. In another four lesions, the diameter of the cervical ICA was decreased in the first three weeks and dilated over the next three weeks. Angiographically, these lesions had a small intimal flap at the balloon dilated portion, which was speculated to cause the turbulent flow in the first stage. In the remaining 2 lesions, restenotic changes in cervical ICAs were observed within three weeks after PTA. Follow-up angiography was performed over three months after PTA in five cases of this series and compared with MRA. Consequently, the diameters of the cervical ICA between angiography and MRA were closely correlated. The evaluation of the lesion after PTA of the cervical ICA demonstrated that MRA is beneficial, but within three weeks after PTA, caution should be paid for underestimation of the small intimal flap on MRA.

AbstractSurgical treatment of giant aneurysms often poses significant challenges. Endovascular techniques have evolved exponentially over the last decades, and most of these complex aneurysms can be treated with flow-diverting techniques; however, successful obliteration of all giant aneurysms is not always possible with endovascular flow-diverting techniques. Although the need for microsurgical intervention has undoubtedly diminished, a versatile-thinking surgeon should keep in mind that obliteration of these aneurysms combined with revascularizing the distal circulation via extracranial–intracranial bypass techniques can provide a potentially life-long durable solution. The key to curing these pathologies is to utilize interdisciplinary decision making with a robust knowledge of the pros and cons of different treatment approaches. Herein, we present a case of a giant posterior communicating segment aneurysm of the left supraclinoid internal carotid artery (ICA), which was treated by obliteration (Fig. 1). Extradural anterior clinoidectomy was used to provide exposure of the supraclinoidal ICA proximal to the aneurysm, and revascularization of the distal circulation was achieved with a common carotid artery to M2-superior trunk bypass using a radial artery interposition graft (Fig. 2). The patient was a 62-year-old female who presented with vision loss in her left eye but was otherwise neurologically intact. She had a history of two unsuccessful flow-diverting stent placement attempts 2 months prior to this surgery. Postoperatively, the patient woke up without any deficits, with her left eye vision partially recovered and ultimately returning to normal at 1-year follow-up. Computed tomography (CT) angiography at a 1-year follow-up showed complete obliteration of the aneurysm and successful revascularization of the distal circulation.The link to the video can be found at: https://youtu.be/3Zz-ecvlDIc .

We describe a case of giant cervical internal carotid aneurysm successfully treated by endovascular trapping. A 57-year-old woman with a history of maxillary contusion seven years before presented with pharyngeal discomfort during swallowing. MRI revealed a 4 cm mass in the right parapharyngeal space. A common carotid angiogram revealed a giant aneurysm with a wide neck originating from the cervical internal carotid artery; kinking of the internal carotid artery was noted at a point distal to the carotid bifurcation. Analysis of cerebral blood flow by SPECT during a balloon occlusion test showed no hypoperfusion areas, and the patient underwent endovascular trapping. There were no neurological or other complications after the procedure. A follow-up MRI revealed complete thrombosis of the aneurysm. Our results show that endovascular trapping for pseudoaneurysm of the cervical internal carotid artery can be a reliable and effective treatment in patients who tolerate a balloon occlusion test.

Abstract Introduction Despite intravenous thrombolysis (IVT) and endovascular treatment (EVT) have been demonstrated effective in acute ischemic stroke (AIS) due to large vessel occlusions, there are still no conclusive data to guide treatment in stroke due to cervical internal carotid artery (ICA) occlusion. We systematically reviewed available literature to compare IVT, EVT, and bridging (IVT + EVT) and define optimal treatment. Methods Systematic review followed predefined protocol (Open-Science-Framework osf.io/bfykj). MEDLINE, EMBASE, and Cochrane CENTRAL were searched. Results were restricted to studies in English, with sample size ≥ 10 and follow-up ≥30 days. Primary outcomes were favorable outcome (mRS ≤ 2), mortality, and symptomatic intracerebral hemorrhage(sICH), defined according to study original report. Newcastle-Ottawa scale was used for bias assessment. Results Seven records of 930 screened were included in meta-analysis. Quality of studies was low-to-fair in 5, good in 2. IVT (n = 450) did not differ for favorable outcome and mortality compared to EVT (n = 150), though having lower rate of sICH (OR = 0.4, 95% CI 0.2–0.8). Compared to IVT, bridging (IVT + EVT) was associated with higher rate of favorable outcome (OR = 2.2, 95% CI 1.3–3.7). Compared to EVT, bridging (IVT + EVT) provided higher rate of favorable outcome (OR = 1.9, 95% CI 1.1–3.4), with a marginally increased risk of sICH (OR = 2.1, 95% CI 1–4.4) but similar mortality rates. Conclusions Our systematic review highlights that, in acute ischemic stroke associated with isolated cervical ICA occlusion, bridging (IVT + EVT) might lead to higher rate of functional independence at follow-up, without increasing mortality. The low quality of available studies prevents from drawing firm conclusions, and randomized-controlled clinical trials are critically needed to define optimal treatment in this AIS subgroup.

Cervical Internal Carotid Artery

The purpose of this study was to determine the value of stenting in the treatment of occlusive vascular disease involving the cervical internal carotid artery. Clinical and angiographical results of stenting were compared those of conventional angioplasty alone up to 20 months of follow-up. The Palmaz-Schatz stent was implanted in two patients with acute intimal dissection, whereas conventional angioplasty alone was performed in seven patients with arteriosclerotic stenosis. Initial procedural success was achieved in all the patients, and acute or subacute complications were not encountered at all. One of the patients (14%) treated with conventional angioplasty alone developed late restenosis at three-month follow-up. The patients treated with stenting revealed satisfactory results clinically and angiographically. The present results may suggest that stenting is an effective and safe method to treat dissection of cervical internal carotid artery, but larger clinical trials as well as experimental studies would be necessary to define the indications and refine the stents.

Endoscopic endonasal surgery on a 36-year-old man was complicated by perforation of the right internal carotid artery. The immediate, substantial haemorrhage was controlled by packing the sphenoid sinus. Intra-arterial angiography of the right internal carotid artery showed small irregularities proximal to the ophthalmic artery. A follow-up examination two weeks later documented a large pseudoaneurysm in the initially irregular arterial segment, which was successfully treated by endovascular coiling.This case report illustrates the need for angiographic follow-up examinations following traumatic intracranial vessel injury in order to identify late pseudoaneurysm development.
