1/36. Stenting of the extracranial internal carotid artery for dissecting aneurysm.Symptomatic dissecting aneurysms of the extracranial internal carotid artery are not frequent. Medical treatment of these lesions can be ineffective and surgical options present high morbidity. We describe a case successfully treated with endovascular therapy, using a self-expanding stent. The advantages of the endovascular treatment and the rationale of the use of self-expanding stents are discussed.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/36. Circulating antineutrophil autoantibodies in a child with isolated central nervous system vasculitis.An 8-year old girl with history of twisted neck and painful swelling on the left side of the neck was found to have malfunction of glossopharyngeal and hypoglossal nerves on the left side. magnetic resonance angiography revealed a giant aneurysm of the internal carotid artery surrounded by a widespread inflammatory tumor. cerebral angiography disclosed a large, false aneurysm with almost complete compression of the internal carotid artery. Circulating antineutrophil cytoplasmic autoantibodies (titer 1:2560) and high levels of antibodies against antiproteinase 3 were detectable. This observation indicates that these autoantibodies may be a diagnostic tool in children in whom an undiagnosed central nervous system inflammatory disease is present.- - - - - - - - - - ranking = 0.4keywords = aneurysm (Clic here for more details about this article) |
3/36. Internal carotid artery pseudoaneurysm related to pregnancy.Arterial rupture is a common cause of maternal death. The increased tendency of true and false aneurysms to develop or rupture with advancing gestational age suggests that hemodynamic, hormonal, or other physiologic changes of pregnancy may play a role in their formation. To our knowledge, pseudoaneurysm formation from a carotid dissection or a ruptured true aneurysm related to pregnancy has not been previously reported. We report the successful repair of a large extracranial internal carotid artery pseudoaneurysm related to pregnancy. The clinical presentation, diagnostic modalities, surgical exposure, and treatment options for high internal carotid artery aneurysms will be discussed.- - - - - - - - - - ranking = 2.4786254103823keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
4/36. aneurysm dissection of the extracranial internal carotid artery.aneurysm of the extracranial internal carotid artery is a rare event. This is a pathology with an elevated mortality of 70%. The most important etiologic factor is atherosclerosis. Here we report a case of surgically treated extracranial internal carotid artery (ICA) aneurysm. A 77-year-old man noticed a laterocervical pulsatile mass. color Doppler ultrasonography revealed an ICA aneurysm related to a parietal thrombosis. The ICA aneurysm was confirmed by intra-arterial digital subtraction angiography, and cerebral computer tomography (CT) was negative. Surgical treatment reconstruction with the interposition of a part of the great saphenous vein was indicated. Exploration of the aneurysmatic wall revealed a posterolateral dissection. In this paper are discussed clinical and therapeutic implications.- - - - - - - - - - ranking = 0.8keywords = aneurysm (Clic here for more details about this article) |
5/36. Ventriculitis due to cryptococcus uniguttulatus.Infections due to non-neoformans cryptococci are rare. We report the first case of a human infection caused by cryptococcus uniguttulatus. Ventriculitis caused by this organism developed in a 65-year-old woman who had had repair of an internal carotid aneurysm. in vitro sensitivity testing showed the cryptococcus species sensitive to amphotericin b and itraconazole. Treatment with amphotericin led to resolution of the infection.- - - - - - - - - - ranking = 0.2keywords = aneurysm (Clic here for more details about this article) |
6/36. Bilateral spontaneous dissection of the internal carotid arteries--a case report.A 41-year-old African American man presented with an acute stroke secondary to bilateral spontaneous internal carotid artery dissections following exercise. Spontaneous bilateral carotid artery dissection is an unusual and uncommon occurrence that can be successfully diagnosed by color-flow duplex ultrasonography and magnetic resonance imaging/magnetic resonance angiography (MRI/MRA) imaging. A review of the literature and the authors' experience supports initial medical management of these patients. Surgery should be considered for those patients who exhibit progressive neurologic symptoms during medical management or when significant carotid artery complications, aneurysms, or flow-limiting stenoses persist.- - - - - - - - - - ranking = 0.2keywords = aneurysm (Clic here for more details about this article) |
7/36. Treatment of internal carotid artery dissections with endovascular stent placement: report of two cases.Extracranial carotid artery dissection may manifest as arterial stenosis or occlusion, or as dissecting aneurysm formation. Anticoagulation and/or antiplatelet therapy is the first-line treatment, but because it is effective and less invasive than other procedures, endovascular treatment of carotid artery dissection has recently attracted interest. We encountered two consecutive cases of trauma-related extracranial internal carotid artery dissection, one in the suprabulbar portion and one in the subpetrosal portion. We managed the patient with suprabulbar dissection using a self-expandable metallic stent and managed the patient with subpetrosal dissection using a balloon-expandable metallic stent. In both patients the dissecting aneurysm disappeared, and at follow-up improved luminal patency was observed.- - - - - - - - - - ranking = 0.4keywords = aneurysm (Clic here for more details about this article) |
8/36. Pseudoaneurysm of the internal carotid artery: treatment with a covered stent.dissection of the cervical segment of the internal carotid artery may occur spontaneously or after trauma. We report the management of a 53-year-old right-handed man with progressive dizziness and neck pain 6 weeks after a motor vehicle collision. The clinical and neurologic examinations were normal. The CT scan led to the diagnosis of a pseudoaneurysm of the right internal carotid artery near the skull base. We successfully treated this post-traumatic lesion with a covered stent. The patient underwent the endovascular procedure under general anesthesia and transcranial Doppler monitoring. No neurologic event was observed. Obliteration of the pseudoaneurysm with preservation of the carotid artery was achieved. The patient was discharged from the hospital 72 hr later with no complications. Clinical and imaging follow-up at 6 months was unremarkable.- - - - - - - - - - ranking = 1.4262084701274keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
9/36. Repair of a tear at the base of a blister-like aneurysm with suturing and an encircling clip: technical note.OBJECTIVE: An aneurysm can produce large defects in the parent vessel if the aneurysm tears at the neck of the vessel. The authors present a technique to repair a tear at the base of a blister-like aneurysm encountered during microsurgical clipping of an anterior wall aneurysm of the internal carotid artery. methods: The repair technique involved suturing and covering the aneurysm with an encircling aneurysm clip. A large tear had destroyed the vessel's tubular structure, and repair was not sufficient using an encircling clip alone. Two microsuture stitches were placed on the tear, so that a split artery re-formed a tubular structure. The lesion was then covered with Surgicel (Ethicon, Inc., Somerville, NJ) and fibrin glue. When the Surgicel and fibrin glue were applied, the temporary clip on the distal internal carotid artery was removed for a moment, allowing retrograde blood flow to provide the counterforce necessary to maintain the vessel's tubular structure. An encircling clip was then applied to cover the entire circumference of the lesion. RESULTS: This method required only a short occlusion time for arterial repair, thus helping avoid ischemic complications. The patient awoke with transient hemiparesis, but recovery was prompt. CONCLUSION: This technique is useful for repairing an aneurysmal tear at its base, especially if the tear is large.- - - - - - - - - - ranking = 2.2keywords = aneurysm (Clic here for more details about this article) |
10/36. Endovascular treatment of an internal carotid artery pseudoaneurysm following transsphenoidal surgery. Case report.Internal carotid artery (ICA) pseudoaneurysm formation following transsphenoidal surgery is a rare but potentially lethal complication. Direct surgical repair with preservation of the ICA may be difficult. The feasibility of endovascular coil embolization with parent artery preservation for an iatrogenic ICA pseudoaneurysm is undefined. A 40-year-old man was referred to the authors' institution after identification of a pseudoaneurysm of the left ICA following transsphenoidal resection of a pituitary macroadenoma. The pseudoaneurysm was treated via an endovascular approach that included stent-assisted coil embolization of the lesion. Follow-up angiographic studies obtained 1 year later demonstrated complete occlusion of the aneurysm, and the patient remains asymptomatic. Stent-assisted coil embolization of this iatrogenic pseudoaneurysm was successful in achieving complete, angiographically confirmed aneurysm obliteration, with preservation of the ICA and short-term prevention of hemorrhage or carotidcavernous fistula. The endovascular method provided an effective, relatively low-risk treatment for this difficult lesion, and was an excellent alternative to direct surgical repair. Nonetheless, long-term follow-up review is required before definitive treatment recommendations can be made.- - - - - - - - - - ranking = 3.2179381155734keywords = aneurysm, pseudoaneurysm (Clic here for more details about this article) |
