1/6. Splaying of the carotid bifurcation caused by a cervical sympathetic chain schwannoma.Splaying of the carotid bifurcation revealed by an imaging study is usually indicative of a carotid body tumor, but there are other possibilities. To promote awareness of a cervical sympathetic chain schwannoma as another cause of splaying of the carotid bifurcation, we present a case of cervical sympathetic chain schwannoma, with an additional 7 cases in the English-language literature, and discuss the relationship between the great vessels of the neck and a carotid body tumor or a schwannoma of the cervical sympathetic chain or vagus nerve from an anatomic viewpoint. We conclude that splaying of the carotid bifurcation with hypervascularity suggests a carotid body tumor, whereas in cases without hypervascularity, a cervical sympathetic chain schwannoma is another possibility. vagus nerve schwannomas can separate the internal jugular vein and internal carotid artery, but seldom widen the carotid bifurcation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/6. Wallenberg's syndrome caused by a craniopharyngioma "en plaque".Wallenberg's syndrome is the clinical manifestation of the obliteration of arterial blood vessels supplying the dorsolateral part of the medulla oblongata, the posterior inferior cerebellar artery being involved in most cases. A patient is described in whom the typical features of Wallenberg's syndrome correlated with cystic necrosis in the perfusion area of the posterior inferior cerebellar artery. A craniopharyngioma spreading along the pons and involving the posterior inferior cerebellar artery, the basilar artery, and its branches was found to be responsible for the infarction of the dorsolateral medulla oblongata.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/6. Intimal disruption of major cerebral vasculature following blunt trauma.A child with blunt traumatic intimal disruption involving the major vessels responsible for cerebral circulation was treated by operation. The injured vessels included both common carotid arteries, both vertebral arteries, and the left subclavian artery. The carotid injuries were treated by saphenous vein interposition grafts, whereas the left subclavian and vertebral arteries were ligated. The patient sustained no neurological deficit and is now completely well 2 years after treatment. The case reported herein is unique in that total intimal disruption of the four major vessels responsible for cerebral flow was treated by operation, resulting in complete recovery. The successful outcome underscores the importance of complete angiographic evaluation and adequate operative exposure in such cases.- - - - - - - - - - ranking = 3keywords = vessel (Clic here for more details about this article) |
4/6. Horner's syndrome secondary to angiogram negative, subadventitial carotid artery dissection.A 59-year-old man presented with the acute onset of paresthesias and pain in the left neck, face, and forehead. On subsequent investigation he was found to have a subadventitial type of carotid artery dissection, producing an ipsilateral Horner's syndrome with normal carotid angiography. MRI imaging of the neck structures, using fat saturation technique, showed the subadventitial dissection, sparing the vessel lumen. MRI offers a non-invasive method of diagnosis and follow-up for carotid artery dissection.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/6. infection-associated cervical artery dissection. Three cases.BACKGROUND: The pathogenesis of cervical artery dissection remains unknown. infection-mediated damage of the arterial wall may be one contributing mechanism. We present three male patients with respiratory infection prior to cervical artery dissection. CASE DESCRIPTIONS: Case 1: During an upper respiratory tract infection, a 49-year-old patient developed bilateral carotid and vertebral artery dissection with complete vessel restitution. Case 2: Within 3 years, a 40-year-old patient experienced two episodes of bilateral internal carotid artery dissection, both preceded by febrile upper respiratory tract infection. Case 3: A 52-year-old patient developed right-sided and, 2 years later, left-sided internal carotid artery dissection, each following upper respiratory tract infection. CONCLUSIONS: infection may be a trigger factor in the pathogenesis of cervical artery dissection.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/6. Endovascular stent treatment of cervical internal carotid artery aneurysms with parent vessel preservation.BACKGROUND: Aneurysms involving the cervical portion of the internal carotid artery (ICA) frequently result from prior trauma or dissection. CASE DESCRIPTIONS: Two patients are reported with cervical internal carotid artery aneurysms. In both cases, disease involving the contralateral ICA precluded safe treatment of the aneurysms by ICA occlusion. Endovascular stents placed across the diseased portion of the artery resulted in thrombosis of the aneurysm with preservation of the parent artery. CONCLUSION: Endovascular stent placement should be considered for treatment of aneurysms involving the cervical ICA when preservation of the parent vessel is necessary.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
