Methods There were six patients with traumatic carotid artery pseudoaneurysm including three patients of cavernous pseudoaneurysm combined with carotid-cavernous fistula (CCF), two with simple traumatic carotid artery pseudoaneurysm and one with traumatic carotid artery pseudoaneurysm that was found after CCF embolization with detachable balloon. The treatment included balloon occlusion for CCF and traumatic carotid pseudoaneurysm in one patient, coil embolization in three and intenal carotid artery balloon occlusion in two. The Clinical manifestations, imaging data, choice of treatment, clinical efficacy, follow-up data and literatures were analyzed to discuss the indications for three treatments. Results There was no cerebral ischemia or surgically-related complication. No epistaxis occurred. The eyeball protrusion restoration was found in three patients and intracranial bruit vanishing in three. Vision was improved one patient after half a year follow-up. The pupils shrank in three patients during follow - up. Digital subtraction angiography (DSA) showed no recurrence of pseudoaneurysm. Conclusions Endovascular treatment is the preferred choice of treatment for traumatic carotid artery pseudoaneurysm. The occlusion or parent artery balloon occlusion can be used when the pseudoaneurysm is combined with CCF. Coil embolization can be used for shoes with narrow neck, stent technology combined with coil embolization for those with wide neck and the covered stent for the rock section of the internal carotid artery. 相似文献

BACKGROUND AND PURPOSE: Endovascular techniques are the methods of choice for the treatment of patients with carotid cavernous fistulas. We report our experience using stent-assisted coil placement for treatment of patients with high-flow fistulas that are associated with severe laceration of the internal carotid artery. METHODS: In a retrospective review of an internal endovascular therapy database covering the interval between October 2001 and October 2003, we identified a total of 5 patients presenting with 6 high-flow type A carotid cavernous fistulas (one had a bilateral fistula) that were associated with severe laceration of the internal carotid artery. All were treated first with stenting of the injured segment of the internal carotid artery followed by transarterial (3/6) and/or transvenous (4/6) obliteration of the fistula with detachable platinum coils. In 2 cases, a liquid adhesive was also used. In all instances, a compliant balloon was inflated within the stented arterial segment during coil deposition to avoid extension of coils into the parent artery. RESULTS: All 6 fistulas were obliterated, and each internal carotid artery was successfully reconstructed. Except for posttraumatic cranial nerve dysfunction in 1 patient, clinical outcome was very good. Follow-up angiograms in 3 of the 6 patients obtained at intervals between 3 and 6 months (mean, 4.5 months) revealed no fistula recurrence and no evidence of intimal hyperplasia within the stent. CONCLUSION: In this series of patients with high-flow carotid cavernous fistula associated with severe injury to the internal carotid artery, stent-assisted coil placement offered a safe and effective treatment. Stent-assisted coil placement may increase the ability to successfully treat fistulas with severe injury to the internal carotid artery with preservation of the parent artery. 相似文献

Angiographic follow-up of traumatic carotid cavernous fistulas treated with endovascular stent graft placement 总被引:6,自引:0,他引:6
Archondakis E Pero G Valvassori L Boccardi E Scialfa G 《AJNR. American journal of neuroradiology》2007,28(2):342-347
BACKGROUND AND PURPOSE: Endovascular treatment (EVT) of carotid cavernous fistulas (CCFs) is based on various techniques, mainly those using detachable balloons. Coronary covered stent grafts have been sporadically used in the intracranial arteries and only 2 traumatic CCFs have been reported in the literature; moreover, there is poor information about the long-term follow-up. We present 8 cases of CCFs treated by the placement of a covered stent, 5 of which have a 1-year clinical and angiographic follow-up. METHODS: Eight patients with posttraumatic CCF were treated by positioning a covered stent in the intracranial internal carotid artery (ICA) to occlude the fistula. They received periodic clinical and angiographic follow-up to evaluate the patency and the stability of clinical results. RESULTS: In all cases, the symptoms related to the CCF regressed after treatment and did not recur in the follow-up. Two patients presented residual filling of the CCF at the end of the procedure. The angiographic follow-up revealed in 6 patients of 7 a good patency of the ICA; in 1 patient, there was an ICA asymptomatic occlusion. One patient required transvenous coil occlusion of the cavernous sinus. CONCLUSION: When standard treatments fail, covered stent grafts can be used as a valid alternative in the treatment of CCFs, but more data are needed, especially in the long-term follow-up. 相似文献

Depicting cerebral veins by three-dimensional CT angiography before surgical clipping of aneurysms 总被引:3,自引:0,他引:3

BACKGROUND AND PURPOSE: Cerebral veins show wide variation, and unexpected veins occasionally limit surgical procedures for clipping of cerebral aneurysms. This study was undertaken to assess the utility of three-dimensional CT angiography (3D-CTA) in the evaluation of venous anatomy before surgical clipping of cerebral aneurysms. METHODS: 3D-CTA was performed in 19 patients before pterional craniotomy. The venous anatomy visualized by use of 3D-CTA was compared retrospectively with intraoperative findings. RESULTS: 3D-CTA clearly depicted the superficial sylvian veins (SSVs) in 17 of 19 cases. In three of these 17 cases, 3D-CTA failed to reveal the additional connecting veins from SSVs to the midportion of the sphenoid wing. 3D-CTA also depicted bridging veins from: 1) the basal vein of Rosenthal to the sphenoparietal sinus (SPS) (three cases); 2) a junction of the anterior cerebral vein and the deep middle cerebral vein to the SPS (two cases); 3) the anterior cerebral vein into the cavernous sinus (one case); and 4) the deep middle cerebral vein to the cavernous sinus in one case. Surgical findings corresponded well with the angiographic findings. 3D-CTA depicted bridging veins from the frontal base into the SPS in two cases; retraction of the frontal lobe was severely limited in these cases. 3D-CTA also exhibited anatomic variation of deep cerebral veins, which suggests the utility of 3D-CTA in evaluating the risks carried by sacrifice of some bridging veins. In two patients, aneurysmal dissection was restricted because of adhering veins. 3D-CTA depicted these cerebral veins to be lying in contact with the aneurysm. In one case, the contiguous vein was hidden behind a large middle cerebral artery aneurysm; 3D-CTA was helpful for visualization of this vein. CONCLUSION: 3D-CTA can clearly depict the venous anatomy of the brain and is useful for surgical planning of a pterional or temporopolar approach for cerebral aneurysms. 相似文献

Direct caroticocavernous fistula and traumatic dissection of the ipsilateral internal carotid artery: endovascular treatment 总被引:3,自引:0,他引:3
After severe craniocerebral trauma a 14-year-old boy developed progressive exophthalmos with venous congestion and chemosis,
due to a direct caroticocavernous fistula. Angiography revealed traumatic occlusion of the ipsilateral internal carotid artery
and absence of the inferior petrosal sinus. After failure of an approach via the anterior and posterior communicating arteries,
the cavernous sinus was successfully catheterised through the occluded internal carotid artery, and embolisation performed
with coils.

We report an original method of transcatheter closure of an arteriovenous fistula using the combination of an Amplatzer PDA
occluder and a carotid stent. The fistula was between the left carotid artery and the brachiocephalic vein. The patient had
significant left-to-right shunt and was highly symptomatic. Due to the large orifice and pseudoaneurysmatic enlargement of
the fistula, we had to use a large Amplatzer PDA occluder and the protruding part of the PDA device disk had to be covered
with a carotid stent. The fistula was completely closed. The patient stopped having symptoms and, 2 years after the procedure,
the effect persists. 相似文献

Spontaneous resolution of symptoms in an infant with a congenital dural caroticocavernous fistula 总被引:1,自引:1,他引:0

We report a 5-week-old boy with a congenital dural caroticocavernous fistula (CCF). He had gradually progressive proptosis, dilated conjunctival veins, chemosis, abducens nerve palsy and an objective bruit. Angiography of the right common carotid artery revealed fistulous communication in the cavernous sinus (CS) region. The CS was fed by the middle meningeal artery and drained through the superior ophthalmic vein and the superior petrosal vein. The child's symptoms and signs disappeared within a few weeks and did not recur over 11 months. At that time, however, angiography still showed a small communication between the right external carotid artery and the CS. 相似文献

A 58-year-old man developed a self-occluding arteriovenous fistula following stent-grafting of the right internal carotid artery (ICA). Due to prolonged ischaemic neurological deficits carotid angiography had been performed 3 weeks previously. It revealed marked atherosclerotic lesions predominantly narrowing the distal right carotid siphon. MRI confirmed ischaemic lesions and massive deficits of perfusion in the right ICA cerebral territory. Stent-grafting was performed successfully, but subsequent angiography revealed a new arteriovenous fistula adjacent to the stent, between the right carotid siphon and the cavernous sinus. On angiography 10 days later, the fistula no longer was present, and flow MRI were normal; the patient was by then asymptomatic. Arteriovenous fistula can thus complicate following endovascular stenting. 相似文献

Cerebral MR venography 总被引:5,自引:0,他引:5
Pui MH 《Clinical imaging》2004,28(2):85-89
This paper illustrates the technique and clinical use of cerebral MR venography (MRV). Dural sinus thrombosis is detected by both two-dimensional time-of-flight (TOF) and three-dimensional phase-contrast (PC) techniques. Venous angiomas are demonstrated by the three-dimensional PC method. The arterial feeders, nidus and draining veins of cerebral arteriovenous malformation (AVM) can be visualized on contrast-enhanced TOF three-dimensional MR angiogram. The high-flow draining veins of cerebral and dural AVMs, vein of Galen malformation and carotid cavernous fistula are better seen on contrast-enhanced three-dimensional gradient-echo MRV. 相似文献

We present a case of an arteriovenous malformation (AVM) where standard MR angiography demonstrated an enlarged basal vein of Rosenthal. The lenticulostriate branches of the middle cerebral artery were suggested but not conclusively shown, as the feeders of the AVM. Therefore, it could not be determined whether the enlarged vein was part of an AVM or of a venous angioma. By using a saturation pulse inferior to the image volume including the basal vein of Rosenthal and the middle cerebral artery, the transmission of "black blood" to the basal vein of Rosenthal was demonstrated. This implied early venous draining, which confirmed that the lesion represented an AVM. 相似文献

A 27-year-old man with a traumatic direct dural arteriovenous fistula (DAVF) was treated using embolisation microcoils. He had suffered blunt trauma to the head while drunk and was aware of no neurological deficit. A few days after the accident, however, he noticed a bruit in the right temple. Angiography demonstrated a direct DAVF fed by the right middle meningeal artery and draining into a right temporal dural vein and the ipsilateral cavernous sinus. A Tracker-18 catheter was passed without difficulty through the fistula and the draining vein was then embolised from distal to proximal with microcoils, and finally the fistula was occluded with microcoils, resulting in total obliteration of the fistula. Immediately after the embolisation, the patient could no longer hear the bruit. Thus, when a microcatheter can be introduced into the draining vein, microcoils can be used as emboli in the treatment of direct DAVF. 相似文献

We report a case of a 34-year-old female with type IV Ehlers-Danlos syndrome diagnosed with a carotid cavernous fistula presenting with progressive proptosis. Endovascular embolization using balloons or coils carries a high risk of complications in this group of patients, owing to the extreme fragility of the blood vessels. Initial treatment was conservative until an intracerebral haemorrhage occurred. To avoid transfemoral angiography, the ipsilateral carotid arteries and the internal jugular vein were surgically exposed for insertion of two endovascular sheaths. The patient was transferred from theatre to the angiography suite and the sheaths were used for embolization access. The fistula was closed, with preservation of the carotid artery, using Guglielmi detachable coils deployed in the cavernous sinus from the arterial and venous sides. Rapid resolution of symptoms and signs followed, which was sustained at 6-month follow-up. This technique offers alternative access for endovascular treatment, which may reduce the high incidence of mortality associated with catheter angiography in this condition. 相似文献
