IntroductionEndovascular intervention for cervical carotid artery dissection (CAD) and vertebral artery dissection (VAD) may be indicated in specific circumstances.ObjectiveTo review our institutional experience with endovascular treatment of cervical dissections over the past 20 years to examine indications for treatment, interventional methods, and outcomes.MethodsRetrospective review of a prospectively maintained database to identify patients with extracranial dissection who underwent endovascular intervention between January 1996 and January 2016. Demographic data and details of procedures, outcomes, and complications were extracted.ResultsOf 116 patients [93 CAD, 23 VAD; mean age 44.9 years (range 5–76 years)], 104 underwent stent placement; 11, coil occlusion of the parent artery; and 1, stenting with contralateral vessel occlusion. The cohorts were well matched for age, sex, dissection etiology, and admission and follow-up modified Rankin Scale (mRS) scores. Patients with CAD had significantly more stent placements (p<0.001), failure of medical therapy (p=0.004), and interventions for enlarging pseudoaneurysms (p=0.01) or thromboembolic events (p=0.004). Patients with VAD had significantly more interventions for traumatic occlusion with recanalization (p<0.001). Dissections were spontaneous (n=67), traumatic (n=36), or iatrogenic (n=13). Traumatic dissections in patients with CAD were associated with poor admission mRS scores (p=0.01). Six of 67 (9.0%) patients with spontaneous dissection reported recent chiropractic manipulation. Mean follow-up was 3.5 years (range 1–146 months). Permanent morbidity/mortality was 3.4%, including two deaths. Over a follow-up period of 364 patient-years, 1 stroke occurred (0.27% per year). At last follow-up, 41 previously disabled patients [CAD, 31/93 (33.3%); VAD, 10/23 (43.5%)] were no longer disabled; no patient reported worsened disability.ConclusionsPatients with CAD and VAD differ significantly in presentation, indications for treatment, and treatment methods. Endovascular treatment of CAD and VAD has low procedural morbidity and is associated with a low incidence of future stroke.

Abstract BACKGROUND: Dissection of the carotid and vertebral arteries is an important cause of stroke in young patients. OBJECTIVE: The objective of this study is to compare antithrombotic treatments in patients with carotid and vertebral dissections. METHODS: Three hundred seventy patients with carotid and vertebral artery dissections were included. Univariate and multivariate analyses were conducted to analyze the association between treatment and new or recurrent events and clinical outcome. RESULTS: Mean follow-up was 24.3 months. In patients with spontaneous dissection, 55% received antiplatelets, 29.4% anticoagulation, and 12.6% combined treatment. New or recurrent ischemic and hemorrhagic events occurred in 9.6% of patients on antiplatelets, 10.4% on anticoagulation, and 13.3% on combined treatment. For traumatic dissection, 58.3% received antiplatelets, 26.9% anticoagulation, and 10.2% combined treatment. New or recurrent ischemic and hemorrhagic events occurred in 6.9% on antiplatelets, 11.1% on anticoagulation, and 20% on combined treatment. In patients with intracranial dissection, 63.1% were started on antiplatelets, 19.7% on anticoagulation, and 14.5% on combined treatment. Ischemic and hemorrhagic events occurred in 8.5% on antiplatelet treatment, 15.4% on anticoagulation, and 18.2% on combined treatment. In patients with extracranial dissection, 54.4% were on antiplatelets, 28.9% on anticoagulation, and 11.2% on combined treatment. Ischemic and hemorrhagic events occurred in 10.1% on antiplatelet treatment, 9.3% on anticoagulation, and 13.8% on combined treatment. The association between antithrombotic treatment and ischemic/hemorrhagic events and clinical outcome was not significant for all subtypes of dissection. CONCLUSION: The rate of new or recurrent events is similar with antiplatelet and anticoagulation treatment in treating intracranial and extracranial carotid and vertebral artery dissection.

Injury Mechanisms

Dissection of the extracranial carotid and vertebral arteries is increasingly recognized as a cause of transient ischemic attacks and stroke. The annual incidence of spontaneous carotid artery dissection is 2.5 to 3 per 100,000, while the annual incidence of spontaneous vertebral artery dissection is 1 to 1.5 per 100,000. Traumatic dissection occurs in approximately 1% of all patients with blunt injury mechanisms, and is frequently initially unrecognized. Overall, dissections are estimated to account for only 2% of all ischemic strokes, but they are an important factor in the young, and account for approximately 20% of strokes in patients less than 45 years of age. Arterial dissection can cause ischemic stroke either by thromboemboli forming at the site of injury or as a result of hemodynamic insufficiency due to severe stenosis or occlusion. Available evidence strongly favors embolism as the most common cause. Both anticoagulation and antiplatelet agents have been advocated as treatment methods, but there is limited evidence on which to base these recommendations. A Cochrane review on the topic of antithrombotic drugs for carotid dissection did not identify any randomized trials, and did not find that anticoagulants were superior to antiplatelet agents for the primary outcomes of death and disability. Healing of arterial dissections occurs within three to six months, with resolution of stenosis seen in 90%, and recanalization of occlusions in as many as 50%. Dissecting aneurysms resolve on follow-up imaging in 5- 40%, decrease in size in 15-30%, and remain unchanged in 50-65%. Resolution is more common in vertebral dissections than in carotid dissections. Aneurysm enlargement occurs rarely. The uncommon patient presenting with acute hemodynamic insufficiency should be managed with measures to increase cerebral blood flow, and in this setting emergency stent placement to restore cerebral perfusion may be considered, provided that irreversible infarction has not already occurred.

Clip Occlusion

Background: Recurrent cerebral infarction caused by traumatic extracranial vertebral artery dissection (EVAD) is treated medically and surgically. We report a case of EVAD that was treated using surgical clip occlusion of the V3 segment to prevent recurrent cerebral infarction. Case Description: A 48-year-old man was admitted for a cerebral infarction caused by EVAD and was treated using 200 mg/day cilostazol. Afterward, the cerebral infarction recurred. Digital subtraction angiography revealed that initial severe stenosis of the VA ostium resulted in the final occlusion and that collateral vessels to the VA remained. We continued antiplatelet therapy, but the cerebral infarction recurred due to thromboembolism of the collateral vessels. Parent artery occlusion was planned. We exposed the V3 segment of the VA and clipped it to prevent the recurrence of cerebral infarction. Conclusion: Surgical clip occlusion of the V3 segment was effective for treating recurrent cerebral infarction caused by traumatic EVAD that had remained an issue despite continuing medical therapy.

We present the case of a man in his thirties who had attended the emergency department with complaint of a distressing headache and associated intermittent facial droop with occasional slurred speech. The patient’s symptoms were bizarre in their nature as they were random, not sustained and he had long intervals when he was asymptomatic and was his normal self. During the course of admission his symptoms evolved resulting in neurological deficits which were more sustained, prompting the need for further imaging beyond the initial plain CT brain which showed no abnormality. This led to the diagnosis of vertebral artery dissection (VAD) complicated with an ischaemic stroke in the posterior inferior cerebellar artery distribution (PICA) on MRI/MRA. Dual anti-platelet treatment was commenced with the patient attaining gradual symptomatic improvement prior to discharge. He has reported some degree of neurological sequelae which he described as intermittent poor coordination on follow up visit in clinic after discharge.

Intracranial vertebral artery dissection (IVAD) is a potentially life-threatening disease, which usually presents with ischemic stroke or subarachnoid hemorrhage. IVAD presenting with isolated facial pain is rare, and no case with isolated trigeminal neuralgia- (TN-) like facial pain has been reported. Here, we report the case of a 57-year-old male with IVAD who presented with acute isolated TN-like facial pain that extended from his left cheek to his left forehead and auricle. He felt a brief stabbing pain when his face was touched in the territory of the first and second divisions of the left trigeminal nerve. There were no other neurological signs. Magnetic resonance imaging (MRI) of the brain 7 days after onset revealed dissection of the left intracranial vertebral artery without brain infarction. The pain gradually disappeared in approximately 6 weeks, and the patient remained asymptomatic thereafter, except for a brief episode of vertigo. Follow-up MRI revealed progressive narrowing of the artery without brain infarction. This case indicates that IVAD can present with isolated facial pain that mimics TN. IVAD should be considered in the differential diagnosis of acute facial pain or TN.

✓The authors report the case of a 65-year-old woman with atlantoaxial subluxation caused by rheumatoid arthritis. The patient had been hospitalized because of an infection after a total-knee replacement, when she suddenly lost consciousness and became apneic after an episode of intractable neck pain. Cranial computed tomography scanning demonstrated subarachnoid hemorrhage (SAH), and angiography revealed a dissecting aneurysm of the radiculomedullary artery that had originated from an extracranial vertebral artery dissection at the level of the atlantoaxial joint. Although coil embolization for the parent artery, including the dissecting aneurysm, was performed successfully, the patient died of worsening infection. The authors believe that the SAH occurred because of a ruptured dissecting aneurysm in the intradural portion of the radiculomedullary artery.

✓ The question of whether unruptured intracranial vertebral artery dissections should be treated surgically or nonsurgically still remains unresolved. In this study, six consecutive patients with intracranial vertebral artery dissection presenting with brain-stem ischemia without subarachnoid hemorrhage (SAH) were treated nonsurgically with control of blood pressure and bed rest, and five received follow-up review with serial angiography. No further progression of dissection or associated SAH occurred in any of the cases, and all patients returned to their previous lifestyles. In the serial angiograms in five patients, the findings continued to change during the first few months after onset. Four cases ultimately showed “angiographic cure,” while fusiform aneurysmal dilatation of the affected vessel persisted in one case. In one patient, arterial dissection was visualized on the second angiogram despite negative initial angiographic findings. These results indicate that intracranial vertebral artery dissection presenting without SAH can be treated nonsurgically, with careful angiographic follow-up monitoring. Persistent aneurysmal dilatation as a sequela of arterial dissection seemed to form a subgroup of fusiform aneurysms of the posterior circulation. These aneurysms may be prone to late bleeding and may require surgical treatment.
