Project description:Endovascular treatment of a giant extracranial internal carotid aneurysm by a stent graft implantation was unsuccessful due to a high flow leak directly through the stent graft's coating. The problem was solved deploying a second stent graft inside the previously implanted one resulting in complete exclusion of the aneurysmal sac and patent carotid lumen preservation. The review of the literature did not provide a case using this endovascular strategy. Follow-up for more than 12 months, using CT angiography, showed confirmed aneurysmal exclusion and carotid patency and no clinical complications have been detected.

Project description:Post-endarterectomy pseudoaneurysms (PEPA) are a rare complication of carotid endarterectomy (CEA), but are associated with high morbidity risk. Therefore, once they are diagnosed, treatment is urgent to prevent possible complications such as rupture, embolisation, thrombosis, or airway and cranial nerve compression. In this video, the surgical procedure is shown in a case of PEPA 10 years after CEA with patch angioplasty, which was successfully managed by surgical excision and interposition of great saphenous vein graft. Follow up duplex examination at six months was normal, with patency of the vein graft. This case reiterates the importance of open surgery as the treatment of choice for this difficult clinical setting.

Project description:Introduction: Carotid artery dissection (CAD) and atherosclerotic carotid artery occlusion (ACAO) are major causes of a tandem occlusion in patients with intracranial large vessel occlusion (LVO). Presence of tandem occlusions may hamper intracranial access and potentially increases the risk of procedural complications of endovascular treatment (EVT). Our aim was to assess neurological, functional and technical outcome and complications of EVT for intracranial LVO in patients with CAD in comparison to patients with ACAO and to patients without CAD or ACAO. Methods: We analyzed data of the MR CLEAN trial intervention arm and MR CLEAN Registry, acquired in 16 Dutch EVT-centers. Primary outcome was the change in stroke severity by comparing the National Institute of Health Stroke Scale (NIHSS) score at 24-48 h after treatment vs. baseline. Secondary outcomes included reperfusion rate and symptomatic intracranial hemorrhage (sICH). We compared outcomes and complications between patients with CAD vs. patients with ACAO and patients without CAD or ACAO. Results: In total, we identified 74 (4.7%) patients with CAD, 92 (5.9%) patients with ACAO and 1398 (89.4%) patients without CAD or ACAO. Neurological improvement at short-term after EVT in patients with CAD was significantly better compared to ACAO (resp. mean -5 vs. mean -1 NIHSS point; p = 0.03) and did not differ compared to patients without CAD or ACAO (-4 NIHSS points; p = 0.62). Rates of successful reperfusion in patients with CAD (47%) was comparable to patients with ACAO (47%; p = 1.00), but was less often achieved compared to patients without CAD or ACAO (58%; p = 0.08). Occurrence of sICH did not differ significantly between CAD patients (5%) and ACAO (11%; p = 0.33) or without CAD/ACAO (6%; p = 1.00). Conclusion: EVT in patients with intracranial LVO due to CAD results in neurological improvement comparable to patients without tandem occlusions. Therefore, carotid artery dissection by itself should not be a contraindication for endovascular treatment in stroke patients with intracranial large vessel occlusion. Although more challenging endovascular procedures are to be suspected in both patients with CAD or ACAO, accurate distinction between CAD and ACAO might influence clinical decision making as better clinical outcome can be expected in patients with CAD.

Project description:Introduction and importanceExtracranial carotid aneurysms (ECCAs) are relatively uncommon. Most of these lesions are due to atherosclerosis, trauma, infection, radiotherapy, previous surgery or iatrogenic event. Severe complications include rupture, dysphagia, respiratory symptoms and brain embolization.Case presentationWe report a case of a large saccular aneurysm of the extracranial internal carotid artery (EICA) in a 83-year old asymptomatic woman without any apparent causative history. The patient underwent a successful repair of the aneurysm by aneurysmectomy and primary end-to-end anastomosis between the proximal and distal portion of the remaining vessel with continuity restored without tension.Clinical discussionECCAs are rare with few cases reported in the most recent literature. There is little knowledge of their natural history and management. Both surgical and endovascular as well as medical treatments have been recommended depending on disease-location and comorbidities.ConclusionAlthough treatment should be individualized time by time by evaluating patient's characteristics, the surgical repair could be a safe and effective solution to treat distal EICAs, especially for symptomatic and true growing lesions. The presentation, the diagnostic evaluation, and the successful surgical treatment are discussed.

Project description:Background and purposeDolichoarteriopathies of the extracranial part of the internal carotid artery (ICA) are associated with cerebrovascular events, yet information on their prevalence and risk factors remains limited. The aim of the present study therefore was to study the prevalence and risk factors of dolichoarteriopathies in a sample of patients with cerebrovascular symptoms from the Plaque At RISK (PARISK) study.MethodsIn a random sample of 100 patients from the PARISK study, multidetector computed tomography angiography (MDCTA) was performed as part of clinical workup. On MDCTA, we evaluated the extracranial trajectory of the ICA by measuring the length (in millimeters), the tortuosity index (TI; defined as the ICA length divided by the shortest possible distance from bifurcation to skull base), and dolichoarteriopathy type (tortuosity, coiling or kinking). Next, we investigated the association between cardiovascular risk factors and these measurements using linear and logistic regression analyses.ResultsThe mean (standard deviation) length of the ICA was 93 (± 14) mm, with a median (interquartile range) TI of 1.2 (1.1-1.3). The overall prevalence of dolichoarteriopathies was 69%, with tortuosity being the most common (72%), followed by coiling (20%), and kinking (8%). We found that age and obesity were associated with a higher TI: difference per 10-year increase in age: 0.05 (95% confidence interval [CI] 0.02-0.08) and 0.16 (95% CI 0.07-0.25) for obesity. Obesity and hypercholesterolemia were associated with a more severe type of dolichoarteriopathy (odds ratio [OR] 2.07 [95% CI 1.04-4.12] and OR 2.17 [95% CI 1.02-4.63], respectively).ConclusionDolichoarteriopathies in the extracranial ICA are common in patients with cerebrovascular symptoms, and age, obesity and hypercholesterolemia may play an important role in the pathophysiology of these abnormalities.

Project description:Cases of an endovascular treatment for traumatic aortic injury are extremely rare. A prompt diagnosis of traumatic thoracic aortic pseudoaneurysm through a 3-dimensional computed tomographic angiography of aorta and emergency repair are mandatory to rescue the life-threatening condition. An endovascular treatment is a trend for traumatic aortic injury because of lower invasivity, morbidity and mortality. We reported a rare case of traumatic aortic injury with thoracic aortic pseudoaneurysm definitively diagnosed by the reconstructional computed tomographic angiography of aorta and successfully treated with endovascular stent-graft.

Project description:Internal carotid artery injury is a rare and devastating complication of endoscopic sinus and skull base surgery that has an associated mortality rate of 15%. This case describes a patient who developed massive epistaxis following routine sinus surgery and was eventually diagnosed with a pseudoaneurysm of the cavernous internal carotid artery. Endovascular coiling and Onyx (Covidien, Irvine, California, United States) liquid embolization were ultimately used to completely occlude the internal carotid artery with resolution of bleeding; however, the patient had an unexpected late complication of coil extrusion through the pseudoaneurysm sac into the sphenoid sinus and nasal cavity. The endoscopic skull base team safely excised the coils endoscopically without recurrent bleeding. We describe the multidisciplinary operative management of this case of endovascular coil extrusion to increase awareness of this potentially life-threatening complication.

Project description:Extracranial carotid artery injuries may produce severe haemorrhage, cerebral damage or arteriovenous fistula. Examples of traumatic extracranial carotid-jugular fistula are not frequently reported, especially in forensic medicine. We report a controversial case of an extracranial internal carotid-jugular fistula resulting from a stab wound to the neck. The degree of the injury was classified under "The Standard of Human Body Injury Assessment (2014)" (SIA) in China by forensic examiners. We believe this case report will provide information for the forensic assessment of similar cases.

Project description:Ischemic stroke due to large vessel occlusion (LVO) is a devastating condition. Most LVOs are embolic in nature. Arterial dissection is responsible for only a small proportion of LVOs, is specific in nature and poses some challenges in treatment. We describe 3 cases where patients with stroke caused by carotid artery dissection were treated with mechanical thrombectomy and extensive stenting with good outcome. We believe that mechanical thrombectomy and stenting is a treatment of choice in these cases.

Project description:Objective This case report is designed to illustrate an uncommon presentation of osteoradionecrosis (ORN) of the temporal bone and a treatment method for bloody otorrhea from a pseudoaneurysm of the internal carotid artery (ICA). Design This is a single patient case report Setting University of Missouri-Columbia Hospital and Clinics. Participants The report describes a patient with a history of hypopharyngeal squamous cell carcinoma (SCCA) who was previously treated with chemoradiation therapy and salvage bilateral neck dissections and then presented in a delayed fashion with profuse, episodic bloody otorrhea. Computed tomography (CT) was consistent with ORN of the temporal bone. The patient underwent emergent cerebral angiography. A pseudoaneurysm of the cervicopetrous ICA was confirmed to be the source of the patient's bloody otorrhea. The lesion was treated by endovascular sacrifice of the ICA using the two-catheter coiling technique. Results The patient had no neurologic sequelae or further bleeding after treatment. Conclusions Bloody otorrhea is an uncommon presentation of ORN. Sacrifice of the internal carotid can be considered as a treatment when the source is pseudoaneurysmal.
