Double-balloon technique for embolization of carotid cavernous fistulas

Embolization of a carotid cavernous fistula (CCF) by means of a detachable balloon is an established method for treating CCFs while preserving a patent parent internal carotid artery (ICA). However, failure to embolize the CCF may occur on a few occasions, such as when the balloon cannot pass through the fistula into the cavernous sinus by blood flow, or when the inflated balloon in the cavernous sinus retracts to the carotid artery. Under these circumstances, the ICA may have to be sacrificed in order to treat the CCF. Herein we describe a double-balloon technique for embolization of a CCF. By applying this technique, we successfully treated nine of 11 CCFs, without compromise of the parent ICA when the conventional one-balloon technique failed.

Abstract：

Objective To investigate the indication and result of parental artery occlusion, embolization with coils, stents in treatment of the traumatic carotid artery pseudoaneurysm. 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.     

Angiographic follow-up of traumatic carotid cavernous fistulas treated with endovascular stent graft placement

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.     

可脱球囊治疗外伤性颈内动脉海绵窦瘘

目的：研究外伤性颈内动脉海绵窦瘘的栓塞治疗。材料与方法：本文对5例外伤性颈内动脉海绵窦瘘患者施行了血管内介入栓塞术。所有患者均于手术前行Matas试验。结果：4例患者经可脱球囊栓塞术治疗，颈内动脉海绵瘘消失，颈内动脉保持通畅，颈内动脉海绵窦瘘的临床综合征于治疗后消失。1例由于瘘口较大，球囊不能完整闭塞瘘口，因该患者健侧颈内动脉代偿供应患侧的能力差，故无法栓塞患侧颈内动脉，栓塞术后该患者临床症状及体征有所改善但未能完全消除。结论：栓塞治疗对于外伤性预内动脉海绵窦瘘是一种有效治疗方法。     

Ruptured cavernous sinus aneurysms causing carotid cavernous fistula: incidence, clinical presentation, treatment, and outcome

BACKGROUND AND PURPOSE: In this study, we present our experience with 11 patients with ruptured cavernous sinus aneurysms causing carotid cavernous fistulas (CCFs), to assess the incidence of ruptured cavernous sinus aneurysms causing CCFs and evaluate clinical presentations, treatments, and outcomes. PATIENTS AND METHODS: During a 10-year period, 10 of 689 (1.5%) endovascular-treated ruptured aneurysms were ruptured cavernous sinus aneurysms causing CCF. One additional patient with a CCF died shortly before treatment of intracranial hemorrhage. All patients had audible pulsatile bruit. Exophthalmus, ocular motor palsy, and decreased vision correlated with venous drainage to the superior ophthalmic veins and intracerebral hemorrhage was associated with major cortical venous drainage in 2 patients. RESULTS: Two low-flow CCFs closed spontaneously before treatment with resolution of symptoms; the aneurysms were subsequently treated. Eight CCFs were successfully occluded, 5 by coil occlusion of the aneurysm, one by occlusion of the aneurysm with a balloon, and 2 by simultaneous coil occlusion of the aneurysm and internal carotid artery. There were no complications of treatment. Visual acuity returned to normal in all but one patient, and ophthalmoplegia was cured in 6 of 8 patients. In 2 patients, a remaining abducens palsy was surgically corrected. CONCLUSION: The incidence of CCF by a ruptured cavernous sinus aneurysm was 1.5%. CCF was the presenting symptom in 24.4% of treated symptomatic cavernous sinus aneurysms. Clinical symptoms correlate with venous drainage. Drainage to cortical veins may lead to intracranial hemorrhage. Endovascular treatment with coils is effective in occluding the fistula.     

Endovascular management of carotid-cavernous fistulas

Objective To investigate endovascular treatment of traumatic direct carotid-cavernous fistulas （CCF） and their complications such as pseudoaneurysms. Methods： Over a five-year period, 22 patients with traumatic direct CCFs were treated endovascularly in our institution. Thirteen patients were treated once with the result of CCF occluded, 8 twice and 1 three times. Treatment modalities included balloon occlusion of the CCF, sacrifice of the ipsilateral internal carotid artery with detachable balloon, coll embolization of the cavernous sinus and secondary pseudoaneurysms, and covered-stem management of the pseudoaneurysms. Results All the direct CCFs were successfully managed endovascularly. Four patients developed a pseudoaneurysm after the occlusion of the CCF with an incidence of pseudoaneurysm formation of 18.2% （4/22）. A total number of 8 patients experienced permanent occlusion of the ICA with a rate of ICA occlusion reaching 36.4% （8/22）. Followed up through telephone consultation from 6 months to 5 years, all did well with no recurrence of CCF symptoms and signs. Conclusion Traumatic direct CCFs can be successfully managed with endovascular means. The pseudoaneurysms secondary to the occlusion of the CCFs can be occluded with stent-assisted coiling and implantation of covered stents.     

Transarterial balloon-assisted n-butyl-2-cyanoacrylate embolization of direct carotid cavernous fistulas

BACKGROUND AND PURPOSE: Transarterial detachable balloon embolization of direct carotid cavernous fistulas (DCCFs) has become an optimal treatment. In a few cases, the parent artery has to be sacrificed to achieve morphologic cure. We present our experience with transarterial balloon-assisted n-butyl-2-cyanoacrylate (n-BCA) embolization of DCCFs in which there was failure to achieve angiographic cure and preservation of parent arteries. METHODS: Of 141 patients with traumatic DCCFs who had been treated by transarterial embolization with occlusion of the fistula and parent artery preservation, 18 received transarterial balloon-assisted n-BCA embolization-6 for residual fistula after the balloons detached, 7 for recurrent fistula because of premature balloon deflation or migration, and 5 for repeated puncture of the detachable balloon by the bony fragment at the cavernous sinus. A total of 27 procedures were performed with an average 1.5 attempts per patient, and the volume of the n-BCA mixture varied from 0.5 to 2.3 mL with a mean of 0.83 mL. RESULTS: All DCCFs were successfully occluded by the n-BCA mixture with preservation of parent arteries. One patient with a giant cavernous sinus varix had a fatal subarachnoid hemorrhage. One had a recurrence and was treated by internal carotid artery (ICA) occlusion. Five had asymptomatic pseudoaneurysms at the parent artery. There was no adhesion of the n-BCA mixture to the protective balloon or the microcatheter or n-BCA reflux into the parent arteries. CONCLUSION: Transarterial balloon-assisted n-BCA embolization is a feasible, efficient, and safe treatment for DCCFs when angiographic cure and ICA preservation are not achieved by transarterial detachable balloon embolization.

Cavernous sinus dural fistulae treated by transvenous approach through the facial vein: report of seven cases and review of the literature

BACKGROUND AND PURPOSE: Dural Carotid Cavernous Fistulas (CCFs) can be treated by transarterial and/or transvenous endovascular techniques. The venous route usually goes through the internal jugular vein (IJV) and the inferior petrosal sinus (IPS) up to the pathologic shunts of the cavernous sinus. In case a thrombosed IPS, catheterization through the obstructed sinus is not always possible and a puncture of the superior ophthalmic vein (SOV) can be performed often after a surgical approach. We report our results in the endovascular transvenous treatment of dural CCFs through the facial vein (retrograde catheterization of the IJV, facial vein, angular vein, SOV, and cavernous sinus). METHODS: A retrospective study of seven patients with a dural CCF treated with transvenous embolization via the facial vein was performed. In five patients, the IPS was thrombosed. In one patient, the IPS was patent, but there was not communication between the cavernous sinus compartment in which the CCF shunts were located and the IPS itself. In the only patient with the CCF draining through permeable IPS, the transvenous route through the IPS permitted the occlusion of the posterior CCF shunts and a second session was performed through the facial vein in order to occlude the shunts of the anterior compartment of the cavernous sinus. The other six patients underwent one embolization session only. RESULTS: In all seven cases, it was possible to navigate through the tortuous junction of the angular vein and the SOV. In one patient with a thrombosed SOV, the venous procedure was interrupted because the catheterization through the occluded SOV failed. In the other six patients, after transvenous catheterization of the cavernous sinus via the facial vein, placement of coils resulted in complete occlusion of the dural CCF with clinical cure in four patients and improvement in two. CONCLUSION: In the endovascular treatment of the dural CCFs, the transfemoral approach via the facial vein provides a valuable alternative to other transvenous routes. Catheterization of the cavernous sinus via the facial vein is usually successful. Although this technique requires caution, it allows a safe and effective treatment of these lesions.     

Traumatic carotid cavernous sinus fistula: serial angiographic studies from the day of trauma.

BACKGROUND AND PURPOSEThe purpose of this study was to ascertain the early angiographic features characteristic of traumatic carotid cavernous sinus fistulas (CCFs).METHODSEight patients with severe craniofacial injuries underwent emergency diagnostic and therapeutic angiography for intractable oronasal bleeding, starting on an average of 6.7 hours after trauma. Carotid angiograms and the clinical manifestation of traumatic CCFs were then reviewed retrospectively to determine characteristic angiographic features.RESULTSIn four of the eight patients, no arteriovenous fistulas were found in the cavernous sinuses and symptomatic CCF did not occur during the follow-up period. In the remaining four patients, dural CCFs (Barrow type B) were observed, unilaterally in three patients and bilaterally in one. One of these four patients subsequently became symptomatic and required transarterial coil embolization.CONCLUSIONTraumatic dural CCFs are frequently observed in the early stage of severe craniofacial trauma, if investigated. Although their spontaneous disappearance is known, some of these do become symptomatic and need treatment.

Endovascular treatment strategy for direct carotid-cavernous fistulas resulting from rupture of intracavernous carotid aneurysms

BACKGROUND AND PURPOSE: Reported treatments and outcomes in aneurysmal carotid-cavernous fistulas (CCFs) have been admixed with those of cases considered to be symptomatic of intracavernous aneurysm. However, aneurysmal CCFs have clinical features distinct from those of dural arteriovenous fistulas, and treatment strategies similar to those of traumatic CCF are required. We evaluated our experience in placing detachable balloons in the management of spontaneous CCFs due to rupture of an intracavernous aneurysm. METHODS: Six patients (one man, five women; mean age, 64.7 years) were treated for spontaneous direct CCF at our institution between 1995 and 2001. All patients presented with sudden ocular symptoms including exophthalmos, conjunctival injection, chemosis, and ocular motor palsies. Detachable latex balloons were used as the embolic material in five patients, and in one patient the cavernous sinus was packed transarterially with coils. RESULTS: All six patients were successfully treated by means of transarterial embolization, and symptoms improved within a week. CONCLUSION: Although other techniques using a transvenous approach and/or detachable coils may also be useful, embolization with detachable balloons should be a safe and effective method to immediately occlude the fistula.

Long-term clinical outcome of spontaneous carotid cavernous sinus fistulae supplied by dural branches of the internal carotid artery

We report the long-term clinical outcome of spontaneous carotid cavernous sinus fistulae (CCF) originally supplied by branches arising from the internal carotid artery (Barrow's type B), or type-D lesion that became type B after particulate embolization. A total of 55 patients was included in this study. Their angiography revealed that cortical drainage was absent, and that the arteries supplying the fistulae originated in the dural branches of the internal carotid artery. Thirty-two patients had type-D lesions, which became type-B lesions after obliteration of the external carotid supply by endovascular treatment. The other 23 patients had type-B lesions documented by angiography, and had no embolization. The follow-up period ranged from 8 to 144.5 months. Clinical cure was achieved in 39 patients (70.9%), improvement in eight patients (14.5%), the lesion remained stable in four patients (7.3%), and was aggravated in four patients (7.3%). The number of drainage veins is the only radiographic factor that could predict the outcome. Those patients with single draining veins had a better chance of complete remission. The outcome between the group with original type D lesions after embolization and the group with original type B revealed no statistically significant difference. The time-course to complete cure was significantly shorter in the group with embolization of the external carotid supply. In the four patients whose symptoms were aggravated, embolization was performed, and the result was excellent. The clinical outcome of type-B CCF, or type D converted to type B, is good. Previous external carotid artery embolization can significantly shorten the time to complete cure. Aggressive treatment should be reserved for those who have aggravated symptoms.
