Purpose: To evaluate pulsed Doppler ultrasound and MR angiography (MRA) in the diagnosis of cervicocranial dissection. Material and Methods: Fourteen patients with cervicocranial artery dissection were examined over a 3-year period. Twelve patients had dissection of the extracranial part of the internal carotid artery, and 2 had vertebral artery dissection. All patients were examined with pulsed Doppler ultrasound. In addition, all patients had conventional angiography (n=9) and/or MR imaging including MRA (n=9). Results: Doppler ultrasound disclosed unspecific abnormalities in 11 of 14 dissected vessels; 3 patients had false-negative Doppler findings. MRA showed vessel abnormalities in 9 of 9 patients; 2 vessels were occluded, and 7 vessels had changes typical of dissection (double lumen and/or string sign). Twelve patients had follow-up examinations with pulsed Doppler ultrasound (n=12), conventional angiography (n=3), and MRA/MR (n=11). Follow-up Doppler showed complete or partial normalization in 61 of 9 patients, all confirmed by either angiography or MRA. Conclusion: Our findings suggest that Doppler ultrasound may be used in follow-up of pathologic Doppler findings in known dissections, and that MRA may replace angiography in the confirmative diagnosis of cervicocranial dissection.

A Prospective Study

A prospective study was undertaken using a range-gated, pulsed Doppler velocimeter to study flowpressure relationships in the anterior cerebral artery. Serial velocity and pressure studies were performed with each infant serving as his or her own control. The hypothesis tested was that ill preterm infants sustaining subependymal/intraventricular hemorrhage would have absent autoregulation. The hypothesis has been tested in 88 studies on 32 infants. Of 32 infants studied, 15 were judged to be pressure passive; nine of these children bled. The other 17 infants were not pressure passive; eight of these children bled (P > .05). From these studies, it may be concluded that the pressure passive state is not the final common link in the genesis of subependymal/intravertricular hemorrhage. Pulsed Doppler ultrasound may provide an extremely useful noninvasive technique for studing both the arterial and venous sides of the cerebral circulation.

Carotid And Vertebral Arteries

Spontaneous dissection of the major arteries of the neck is known to increase the risk of stroke or transient ischaemic attack in young and middle-aged adults. Most of the reported cases of arterial dissections in the neck involve one or both paired extracranial carotid or vertebral arteries. Spontaneous dissection of the bilateral internal carotid and vertebral arteries is extremely rare. We report a case of spontaneous bilateral internal carotid artery and vertebral artery dissection while using a prescribed pill for weight loss which contained amphetamine derivative. A review of literature is also provided.

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.
