Cerebral perfusion in patients with unilateral internal carotid artery occlusion by dual post-labeling delays arterial spin labeling imaging

BACKGROUND Global and regional cerebral blood flow(CBF)changes in patients with unilateral internal carotid artery occlusion(ICAO)are unclear when the dual post-labeling delays(PLD)arterial spin labeling(ASL)magnetic resonance imaging(MRI)technique is used.Manual delineation of regions of interest for CBF measurement is time-consuming and laborious.AIM To assess global and regional CBF changes in patients with unilateral ICAO with the ASL-MRI perfusion technique.METHODS Twenty hospitalized patients with ICAO and sex-and age-matched controls were included in the study.Regional CBF was measured by Dr.Brain's ASL software.The present study evaluated differences in global,middle cerebral artery(MCA)territory,anterior cerebral artery territory,and Alberta Stroke Program Early Computed Tomography Score(ASPECTS)regions(including the caudate nucleus,lentiform nucleus,insula ribbon,internal capsule,and M1-M6)and brain lobes(including frontal,parietal,temporal,and insular lobes)between ICAO patients and controls at PLD 1.5 s and PLD 2.5 s.RESULTS When comparing CBF between ICAO patients and controls,the global CBF in ICAO patients was lower at both PLD 1.5 s and PLD 2.5 s;the CBF on the occluded side was lower in 15 brain regions at PLD 1.5 s,and it was lower in 9 brain regions at PLD 2.5 s;the CBF in the contralateral hemisphere was lower in the caudate nucleus and internal capsule at PLD 1.5 s and in M6 at PLD 2.5 s.The global CBF in ICAO patients was lower at PLD 1.5 s than at PLD 2.5 s.The ipsilateral CBF at PLD 1.5 s was lower than that at PLD 2.5 s in 15 regions,whereas the contralateral CBF was lower at PLD 1.5 s than at PLD 2.5 s in 12 regions.The ipsilateral CBF was lower than the contralateral CBF in 15 regions at PLD 1.5 s,and in M6 at PLD 2.5 s.CONCLUSION Unilateral ICAO results in hypoperfusion in the global and MCA territories,especially in the ASPECTS area.Dual PLD settings prove more suitable for accurate CBF quantification in ICAO.

Massive Epistaxis Revealing a Post-Traumatic Aneurysm of the Internal Carotid Artery: A Clinical Case and Review of the Literature

Internal carotid artery (ICA) aneurysms are an unusual but serious cause of epistaxis. This epistaxis is massive and sometimes uncontrollable threatening the vital prognosis of patients. We report the case of a 16-year-old adolescent received in emergency with severe bilateral epistaxis, asthenia and grade-3 left exophthalmos. In his history, the subject had been the victim of an assault six months before consultation. He had received blows on the cephalic extremity with light but repeated epistaxis. The treatment consisted to blood products transfusion and local compression by sterile gazes. An ICA aneurysm in sphenoid sinus has been confirmed in a craniofacial CT scan coupled to vascular opacification. Although the ICA has a variable course in contact with the sphenoid sinus, massive epistaxis would be the consequence of a pronounced dehiscence of the ICA in the sphenoid sinus, particularly in a traumatic context. In front of this type of epistaxis in our context, general practitioners must be able to suspect a ruptured ICA aneurysm in the presence of exophthalmos and a notion of old or recent cranio-encephalic injury. Additionally, due to the high morbidity and mortality of this condition, a monitoring algorithm is necessary for patients with head trauma to facilitate early detection.

Choroidal infarction after internal carotid artery stenting

Dear Editor,We present a case of choroidal infarction along with retinal infarction after carotid artery stenting(CAS),which is a rare condition not reported in the literature.CAS has increasingly been accepted as the mainstay reconstruction method for carotid artery stenosis compared with carotid endarterectomy(CEA)due to no need for general anesthesia.

CAS and CEA in the Treatment of Severe Internal Carotid Artery Stenosis

Objective:To explore the clinical value of carotid artery stent implantation(CAS)and carotid endarterectomy(CEA)in the treatment of patients with severe internal carotid artery stenosis.Methods:88 patients with severe carotid artery stenosis who underwent CAS and CEA in the First People's Hospital of Changde City(hereafter referred as "our hospital")from January 2018 to December 2020 were selected as the research objects and divided into CAS group(n=43)and CEA group(n=45).To understand the clinical application value and feasibility of the two surgical schemes by comparing the general situation,cerebral blood flow,MMSE scale,MOCA scale score and serum miR-145,IGF1R levels of the two surgical schemes.Conclusions:CAS and CEA in the treatment of patients with severe internal carotid artery stenosis,have good curative effect,can effectively improve the patient's cerebral blood flow,regulate serum miR-145,IGF 1R levels,promote the recovery of cognitive function,but relatively speaking,the incidence of stroke and hypotension after CAS is higher,and the incidence of hypertension after CEA is higher.

A Comprehensive Analysis of a Case of Internal Carotid Artery Stenting

With the development of science and technology and the continuous progress of interventional equipment,internal carotid artery stenting has become increasingly popular among patients in view of its advantages,which include high efficiency,minimally invasive,and fast postoperative recovery.It has grown importance as a surgical method for the treatment of severe internal carotid artery stenosis.This paper discusses a rare case of severe internal carotid artery stenosis and its management,where various types of pre-dilatation balloons were not able to be positioned in the stenting process.Relevant solutions have also been proposed in hope to provide a more theoretical and practical basis for clinical work.

Bilateral cerebral infarction in diabetic ketoacidosis and bilateral internal carotid artery occlusion:A case report and review of literature

BACKGROUND Diabetic ketoacidosis(DKA)is a serious complication of type 1 diabetes mellitus(T1DM).Very rarely does DKA lead to cerebral edema,and it is even rarer for it to result in cerebral infarction.Bilateral internal carotid artery occlusion(BICAO)is also rare and can cause fatal stroke.Moreover,case reports about acute cerebral infarction throughout both internal carotid arteries with simultaneous BICAO are very scarce.In this study,we present a patient with BICAO,T1DM,hypertension,and hyperlipidemia,who had a catastrophic bilateral cerebral infarction after a DKA episode.We briefly introduce BICAO and the mechanisms by which DKA results in cerebral infarction.CASE SUMMARY A 41-year-old woman presented with ischemic stroke that took place 3 mo prior over the left corona radiata,bilateral frontal lobe,and parietal lobe with right hemiplegia and Broca’s aphasia.She had a history of hypertension for 5 years,hyperlipidemia for 4 years,hyperthyroidism for 3 years,and T1DM for 31 years.The first brain magnetic resonance imaging not only revealed the aforementioned ischemic lesions but also bilateral internal carotid artery occlusion.She was admitted to our ward for rehabilitation due to prior stroke sequalae.DKA took place on hospital day 2.On hospital day 6,she had a new massive infarction over the bilateral anterior cerebral artery and middle cerebral artery territory.After weeks of aggressive treatment,she remained in a coma and on mechanical ventilation due to respiratory failure.After discussion with her family,compassionate extubation was performed on hospital day 29 and she died.CONCLUSION DKA can lead to cerebral infarction due to several mechanisms.In people with existing BICAO and several stroke risk factors such as hypertension, T1DM,hyperlipidemia, DKA has the potential to cause more serious ischemic strokes.

Percutaneous cervical carotid artery access with stenting of the left internal carotid artery in an elderly patient

To describe the successful endovascular treatment in a nonagenarian with symptomatic internal carotid artery stenosis using direct carotid artery access. An independent 98 year-old man was admitted to our hospital for symptoms of progressive weakness with disorientation and dysphasia. Carotid Duplex ultrasonography was performed which revealed a totally occluded right internal carotid artery and high grade stenosis of the left internal carotid artery by velocities of 608/240 cm/sec. The patient refused surgical endarterectomy and thus he was referred for carotid artery stenting. Using the femoral artery approach and multiple catheter techniques, access to the common carotid artery could not be accomplished safely. The procedure was aborted and he was therefore brought back to the catheterization laboratory the following day for direct carotid access. Carotid artery stenting was accomplished by using of a 6F sheath percutaneously in the left common carotid, cerebral protection device (CPD) and a Nitinol stent. The patient was discharged the following day without complications. At 14 months follow-up the patient is functional and independent without recurrence of symptoms. Carotid artery stenting via direct access can be accomplished in patients when the femoral artery approach is anatomically prohibitive. In this case of advanced age and the patient’s refusal for surgery, direct carotid access was his only option.

Congenital bilateral absence of the common carotid artery and internal carotid artery:a case report and literature review

Absence of the common carotid artery(CCA) and/or internal carotid artery (ICA ) is a kind of rare congenital anomaly. This paper reports one patient with bilateral absence of the CCA and ICA who suffered from cerebral infarction. And the relative literatures of the possible cause and collateral circulation were reviewed.

Metformin effect on internal carotid artery blood flow assessed by area under the curve of carotid artery Doppler in women with polycystic ovarian syndrome

BACKGROUND Insulin resistance(IR)was reported in most polycystic ovarian syndrome(PCOS)cases.Metformin,a biguanide drug,successfully reduced IR.Homeostatic Model Assessment for IR(HOMA-IR)and Doppler parameters assessed metformin's effectiveness.AIM To verify whether the area under the curve of the internal carotid artery(AUC-ICA)Doppler wave can be a useful marker for assessing IR among PCOS cases who presented with menstrual irregularity and were treated with metformin over 6 mo.METHODS An observational,cross-sectional study recruited 54 eligible PCOS women;the anthropometrics were as follows:age,body mass index(BMI),menstrual cycle days,biochemical serum cholesterol,low and high-density lipoprotein,sex hormone-binding globulin,fasting blood glucose,and HOMA-IR,hormonal testosterone,luteinizing hormone over follicle-stimulating hormone ratio,and ultrasonic pulsatility index(PI)and resistance index(RI),carotid artery intima-media thickness(CIMT)and(AUC-ICA)parameters were initially recorded and repeated 3 mo and 6 mo later with metformin tab 500 mg;three times/day for 6 mo.In addition,AUC-ICA was assessed by taking repeated systolic and diastolic wave height measurements.RESULTS Metformin caused a progressive reduction in BMI,menstrual cycle days,biochemical hormonal,and Doppler parameters(CIMT,PI,RI,and AUC-ICA).AUC-ICA correlated strongly to all PCOS parameters.AUC-ICA correlated inversely with treatment time(r=-0.98,P<0.001)and positively with HOMA-IR(r=0.98,P<0.0001).Via the best subset regression model,the AUC-ICA had the highest predictive value for HOMA-IR.CONCLUSION AUC-ICA preceded PI,RI,and CIMT with a strong,meaningful correlation to all PCOS parameters,making it a reliable marker for the assessment of IR,especially during metformin therapy.Further studies are recommended to promote the application in practice.

Treatment of Dissection at the Ophthalmic Segment of Internal Carotid Artery

Objective Intracranial internal carotid artery dissection is a rare case. The purpose of this study was to report the treatment of intracranial internal carotid dissection and the radiologic and clinical result.Material And Method A 67 year-old female patient admitted for lower leg fracture at the outside university hospital. After 6 days later, she presented with left hemiparesis, verbal disturbance and visual disturbance. She transferred to our hospital and evaluated with MRI and Angiography. Angiography show stenosis with ulceration and pseudoaneurysm at the internal carotid artery. The stenosis rate was 63%. At the lesion, ophthalmic artery was poor visualized. Results The intracranial lesion was treated with angioplasty and stenting. After stenting, angiography showed good ophthalmic artery flow. Patients improved visual acuity just after stenting. Conclusions Intracranial angioplasty and stenting will be a good treatment option in a highly selected case.

Fatal Cataclysmic Otorrhagia and Epistaxis Due to a Ruptured Aneurysm of the Petrous Internal Carotid Artery: A Case Report

Background: Aneurysms of the internal carotid artery within the petrous temporal bone are extremely rare;their true incidence is unknown. The exact cause is unclear: they may be congenital or result from trauma, infection, or radiation. Aim: We report a case of massive otorrhagia and epistaxis from a ruptured aneurysm of the petrous internal carotid artery. Case Presentation: A 34-year-old man presented to our department for the first time with repeated left otorrhagia ongoing for 5 years, left sided pulsatile tinnitus and left conductive hearing loss. In his history, we noted a right hemi-corporeal deficit of sudden onset one month ago and the head-CT showed a left frontoparietal subarachnoid hemorrhage without any visualised vascular malformation. Otomicroscopy showed a pulsatile mass visible at the posterior part of the hypotympanum. There was a right-sided hemiparesis estimated at 2/5 with no disorder of the sensitivity. After hemodynamic stabilization, the patient was discharged from the hospital and treatment was scheduled in interventional radiology and neurosurgery unit. Unfortunately the patient presented at home with a cataclysmic hemorrhage by massive otorrhagia and epistaxis and arrived dead at the emergency unit. Conclusion: The treatment of a petrous carotid aneurysm must be carried out quickly considering the risk of rupture leading to a cataclysmic hemorrhage that can be rapidly life threatening.

Recanalization of extracranial internal carotid artery occlusion A 12-year retrospective study

This study aimed to summarize therapy experience of carotid endarterectomy, carotid endarterec- tomy combined with Fogarty catheter embolectomy, and hybrid surgery for the treatment of extrac- ranial internal carotid artery occlusion. The study included 65 patients with extracranial internal ca- rotid artery occlusion who underwent carotid endarterectomy, carotid endarterectomy combined with Fogarty catheter embotectomy, or hybrid surgery in the Department of Neurosurgery, Xuanwu Hospital, Capital Medical University, China between January 2006 and December 2012. Prior to surgery, all patients underwent perfusion CT or xenon CT to evaluate the occlusion. The procedure for each patient was chosen according to digital subtraction angiography data. The carotid artery was successfully recanalized in 46 of 51 patients who underwent carotid endarterectomy, 9 of 10 patients who underwent carotid endarterectomy combined with Fogarty catheter embolectomy, and 3 of 4 patients who underwent hybrid surgery. In patients with symptomatic carotid artery occlusion, the carotid artery can be recanalized by choosing a treatment procedure based on imaging ex- amination findings.

Subfoveal choroidal thickness and volume in severe internal carotid artery stenosis patients

AIM：To demonstrate the differences of retinal and choroidal structure changes in internal carotid artery（ICA） patients of China by enhanced-depth imaging optical coherence tomography（EDI-OCT）.METHODS：A retrospective review was conducted of 46 patients with a diagnosis of ICA stenosis greater than 65% on only one side（the opposite ICA Stenosis had less than 40% stenosis） from June 2015 through June 2016.All of the patients were combined with amaurosis fugax,but without any abnormality with other ocular examination.Thickness and volume of choroid and retina were manually measured by EDI-OCT.Differences were compared between ICA stenosis eyes and fellow eyes.RESULTS：There were no significant differences in the retinal thickness,macular retinal nerve fiber layer（m RNFL） thickness,inner thickness,or outer retinal thickness between the ICA Stenosis group and the control group（P=0.834,0.187,0.552,and 0.903,respectively）.The mean central choroidal thickness of the ICA Stenosis group was significantly lower than that of the control group（239.70±23.76 μm vs 257.46±22.13 μm,P〈0.001）.The percentage of ICA stenosis was significantly associated with the central choroidal thickness,central retinal thickness,foveal center choroidal volume,and foveal center retinal volume（r=0.854,0.678,0.729,and 0.785,respectively;P〈0.001）.There were no significant differences in the retinal and choroidal volume values in the 4 inner and 4 outer sectors between the two groups.CONCLUSION：The choroidal thickness in severe ICA stenosis eyes is lower than in fellow eyes.The choroidal thinning may occur before the retinal changes in patients with ocular ischemic syndrome.Evaluations of choroidal thickness may be useful to choose the optimal therapeutic schedule for ICA patients.

Cerebral infarct secondary to traumatic internal carotid artery dissection

BACKGROUND Traumatic internal carotid artery dissection(TICAD)is rare and can result in severe neurological disability and even death.No consensus regarding its diagnostic screening and management has been established.AIM To investigate the clinical presentation,imaging features,diagnostic workup,and treatment of TICAD.METHODS In this retrospective case series,emergency admissions for TICAD due to closed head injury were analyzed.The demographic,clinical,and radiographic data were retrieved from patient charts and the picture archiving and communication system.RESULTS Six patients(five males and one female,age range of 43-62 years,mean age of 52.67 years)presented with TICAD.Traffic accidents(4/6)were the most frequent cause of TICAD.The clinical presentation was always related to brain hypoperfusion.Imaging examination revealed dissection of the affected artery and corresponding brain infarction.All the patients were definitively diagnosed with TICAD.One patient was treated conservatively,one patient underwent anticoagulant therapy,two patients were given both antiplatelet and anticoagulant drugs,and two patients underwent decompressive craniectomy.One patient fully recovered,while three patients were disabled at follow-up.Two patients died of refractory brain infarction.CONCLUSION TICAD can cause catastrophic outcomes and even refractory brain hernia.Early and efficient diagnosis of TICAD is essential for initiating appropriate treatment.The treatment of TICAD is challenging and variable and is based on clinician discretion on a case-by-case basis.

Spontaneous internal carotid artery pseudoaneurysm complicated with ischemic stroke in a young man:A case report and review of literature

BACKGROUND Carotid artery pseudoaneurysm(PSA)is infrequently encountered in clinical settings.Internal carotid artery(ICA)PSA complicated with ischemic stroke is rare.PSAs are typically caused by iatrogenic injury,trauma,or infection.The underlying mechanisms of spontaneous PSA formation are not well characterized.We report a healthy young man who presented with stroke as a complication of spontaneous PSA of the left ICA.CASE SUMMARY A 30-year-old man working as a ceiling decoration worker was hospitalized due to sudden-onset speech disorder and right lower extremity weakness.Medical history was unremarkable.Brain computed tomography revealed ischemic stroke.Digital subtraction angiography showed a left ICA PSA with mild stenosis.The patient was conservatively managed with oral anticoagulation and antiplatelet therapy.He recovered well and was discharged.The patient was in good condition during follow-up.CONCLUSION The occupational history of patient should be taken into consideration while evaluating the etiology of spontaneous ICA PSA in young people with stroke.

Emergency treatment and anesthesia management of internal carotid artery injury during neurosurgery:Four case reports

BACKGROUND During skull base surgery,intraoperative internal carotid artery(ICA) injury is a catastrophic complication that can lead to fatal blood loss or secondary cerebral ischemia.Appropriate management of ICA injury plays a crucial role in the prognosis of patients.Neurosurgeons have reported multiple techniques and management strategies;however,the literature on managing this complication from the anesthesiologist’s perspective is limited,especially in the aspect of circulation management and airway management when patients need transit for further endovascular treatment.CASE SUMMARY We describe 4 cases of ICA injury during neurosurgery;there were 3 cases of pathologically proven pituitary adenoma and 1 case of cavernous sinus endothelial meningioma.After the onset of ICA injury,all four patients were immediately transferred for endovascular therapy under general anesthesia with vital signs monitored and mechanical ventilation.Three patients were transferred to the hybrid operating room,and one patient was transferred to the catheter operating room.Three patients underwent covered stent implantation,and one patient underwent embolization.All four patients experienced hypovolemic shock and received blood products infusion and vasoactive drugs to maintain stable circulation.After the neurosurgery,one patient was extubated and returned to the ward,and the other three were delayed tracheal extubation and returned to the intensive care unit.One patient died from serious neurological complications after 62 d in the hospital,but the other three showed good clinical outcomes.CONCLUSION ICA injury imposes a high risk of massive hemorrhage and subsequent infarction.Immediate treatment is critical and requires interdisciplinary collaboration among neurosurgeons,anesthesiologists,and interventional neuroradiologists.Effective hemostatic methods,stable hemodynamics sufficient to ensure perfusion of vital organs,airway safety during transit,rapid localization and implementation of appropriate measures to occlude the damaged vessel are strong guarantees of patient safety.

Endoleak management and postoperative surveillance following endovascular repair of internal carotid artery vascular diseases using Willis covered stent

Background:To report the clinical results and experiences of endoleak management and postoperative surveillance following endovascular repair of internal carotid artery vascular diseases(ICAVDs)using Willis covered stents.METHODS:Seventy-three patients with ICAVD who received Willis covered stent implantation between November 2013 and September 2018 were retrospectively reviewed.The clinical data of endoleak management and postoperative surveillance were analyzed.RESULTS:Seventy-three cases with ICAVD,including 57 aneurysms,11 carotid-cavernous sinus fistulas(CCF),and 5 surgical injuries,were all successfully installed with covered stents.Total isolation of ICAVDs was achieved in 59 patients(80.8%),and endoleaks were observed in 14 patients(19.2%).Of the 14 patients with endoleaks,12 had type I endoleaks and 2 had type II;13 had aneurysms and one had CCF.10 patients with type I endoleaks received balloon dilatation,and 7 of them underwent a second stent-graft implantation after then.One patient with type II endoleak received embolization of the branch artery,and another one received follow-up observation.Endoleaks resolved in 6 patients and were minimal in 5 patients after balloon dilatation or the second stent implantation.During the follow-up period,minor endoleaks spontaneously resolved in 4 patients and minimal endoleaks were still demonstrated in 4 patients without enlargement of residual lumen and rupture.CONCLUSIONS:Endoleaks are the major complication after endovascular repair of ICAVDs and represent one of the limitations of this procedure.Improving the understanding and management of endoleaks can be beneficial in the clinical setting,including the popularization and application of this technique.

Primary balloon angioplasty for chronic occlusion of intracranial internal carotid artery: A case report

Chronic occlusion of large intracranial arteries is the main cause of ischemic stroke in China.Patients with symptomatic intracranial artery occlusion and hemodynamic impairment are at high risk of recurrent stroke.Chronic occlusion of the intracranial segment of the internal carotid artery is a common type of intracranial artery occlusion.Medical management is regarded as the standard treatment for this disease.With the development of endovascular treatment,some patients with chronic cerebral artery occlusion have achieved satisfactory results with endovascular therapy.We reported a patient with symptomatic chronic occlusion of the ophthalmic segment of the internal carotid artery.Simple balloon angioplasty was performed,and the occluded ophthalmic segment of the internal carotid artery was successfully recanalized without perioperative complications.At 4 months followup,the internal carotid artery remained patent and perfusion of the right cerebral hemisphere improved dramatically.In addition,we briefly reviewed the relevant literature.

Endovascular treatment of a ruptured pseudoaneurysm of the internal carotid artery in a patient with nasopharyngeal cancer:A case report

BACKGROUND Radiation therapy(RT)for nasopharyngeal cancer can cause several complications.In rare cases,an internal carotid artery pseudoaneurysm can occur,which can be fatal.We report the experience of a nasopharyngeal cancer patient who underwent radiation therapy and subsequently developed a fatal pseudoaneurysm of the petrous internal carotid artery.CASE SUMMARY A 39-year-old man was diagnosed with nasopharyngeal cancer 2 years ago(American Joint Committee on Cancer Stage T3N2M0)and received concurrent chemoradiation therapy.He subsequently relapsed and received chemotherapy.One week after the 4th cycle of chemotherapy,he was admitted to the emergency room of our hospital because of massive epistaxis accompanied by a headache.A pseudoaneurysm of the petrous internal carotid artery was confirmed by digital subtraction angiography(DSA).Stent-assisted endovascular coil embolization was performed and complete occlusion was achieved.No pseudoaneurysm was observed on DSA after coil embolization;however,intermittent epistaxis was maintained even after coil embolization.After seven days,a diagnostic laryngoscopy was performed.Massive bleeding occurred after aspiration of the blood clot during the laryngoscopy and the patient died of hypovolemic shock.In this case,epistaxis may have been a sign of pseudoaneurysm;therefore,treatment such as embolization should be performed promptly,and careful management should be undertaken after treatment.CONCLUSION This case highlights a rare,serious complication of RT in nasopharyngeal cancer and how it should be recognized and treated.

Treatment of extracranial internal carotid artery dissecting aneurysm with SUPERA stent implantation:Two case reports

BACKGROUND There is no standard endovascular treatment for extracranial internal carotid artery dissecting aneurysms.In the past,stent-graft isolation and stent-assisted coil embolization were commonly used for wide-necked and fusiform aneurysms.Here,we present two cases of extracranial internal carotid artery dissecting aneurysms treated successfully using the SUPERA stent.CASE SUMMARY Case 1 was a 57-year-old male patient with sudden right limb weakness and vague speech and diagnosed with cerebral infarction in February 2019.Cervical computed tomographic angiography(CTA)revealed left internal carotid artery dissection with stenosis.CTA at 2 mo showed an eccentric wide-necked dissecting aneurysm(5 mm×5 mm×12 mm,10-mm neck)that was enlarged at 4 mo(7 mm×6 mm×12 mm,11-mm neck).The patient underwent SUPERA stent implantation.His condition was stable in July 2020.Case 2 was a 57-year-old man who suddenly felt dizzy and developed unsteady walking in November 2019.Cervical CTA suggested right internal carotid artery dissecting aneurysm(11 mm×9 mm×31 mm)complicated with severe lumen stenosis(95%).The patient underwent SUPERA stent implantation.The patient had no residual symptoms and was stable in December 2020.CONCLUSION SUPERA stent implantation might achieve good results in treating wide-necked or long fusiform internal carotid artery dissecting aneurysms.
