Abstract
BACKGROUND While coiling is considered the standard treatment for carotid-cavernous fistulas (CCFs), studies demonstrating excellent results using new materials, especially flow diverter (FD) stents and liquid embolisates, are becoming more frequent. The indications and effectiveness of these alternative endovascular techniques remain unclear. METHODS A total of 22 direct and 20 indirect CCFs were included in the study. These were further subdivided based on the embolic material used: coils versus FD stents for direct and coils versus liquid embolisates for indirect CCFs. The subgroups were subjected to statistical analysis. RESULTS An angiographic cure was achieved in 88% of all CCFs, 93% of patients' experienced clinical improvement or remained stable. Direct CCFs were treated with coiling (41%) or with both coils and FD stents (55%). One (4%) patient with a direct CCF was treated with FD stent alone. Statistical analysis comparing these subgroups revealed a significantly higher complete occlusion rate immediately after treatment in the coiling subgroup (67% vs. 23%, p = 0.0409). The occlusion rates at the last follow-up were similar (89% vs. 85%). Indirect CCFs were treated with coiling (35%) or liquid embolisates (65%). All three periprocedural ischemic complications were recorded within the liquid subgroup, resulting in a significantly higher clinical deterioration rate (p = 0.0333). CONCLUSION FD stents in direct and liquid embolisates in indirect fistulas did not demonstrate better angiographic or clinical outcomes compared to convetional coiling. Liquid agents carried a higher risk of ischemic complications. Alternative embolization materials should be reserved for CCFs that cannot be treated with simple coiling.

Abstract
Abstract
Background
Carotid cavernous fistula (CCF) is an abnormal arteriovenous shunt between the carotid artery or its branches, with the cavernous sinus. It is still common in developing countries, and is mostly due to traumatic origin. Endovascular treatment has emerged as the primary mode of treatment of CCF. This is the first study describing the clinical manifestation, angiographic characteristic, and the challenges we face in endovascular treatment of CCF cases in Makassar, Indonesia.
Results
This descriptive study was conducted between January 2019 to March 2022. We reviewed medical records and angiograms of all patients diagnosed with CCF at the Wahidin General Hospital, Makassar. Clinical manifestations, angiogram results, treatment, and outcome data were analyzed. A total of 23 patients were included in this study, with 17 (73.9%) direct CCF (Barrow type A) and 6 (26.1%) indirect CCF (Barrow type B, C, D). The mean age of patients were 32 years old. The three most common clinical manifestations were proptosis (n = 21, 91.3%), headache (n = 14, 60.8%), and chemosis (n = 14, 60.8%). The three most common drainage routes were via the superior ophthalmic vein (n = 23, 100%), inferior petrosal sinus (n = 12, 52.1%), and superficial middle cerebral vein (n = 6, 26.0%). All patients with direct CCF (n = 17) had endovascular treatment, resulting in 13 cases with complete occlusion (76.5%), 3 cases with incomplete occlusion (17.6%), and 1 (5.9%) procedure cancelled due to difficult navigation. Occlusion of fistula was best achieved with detachable coil, with a technical success rate of 90%. In indirect CCF (n = 6), 4 patients were treated conservatively and 2 with endovascular treatment, with complete occlusion in 2 patients.
Conclusions
Carotid cavernous fistula patients commonly presented with orbital symptoms, headache, or neuro-ophthalmologic signs. The most common drainage pattern is via anterior route. Posterior, superior and lateral drainage were not found in indirect CCF. Endovascular treatment is an effective method for fistula closure, especially in the case of direct fistula. Challenges in endovascular treatment are related to the anatomy of the fistula and cavernous sinus.

Abstract
BACKGROUND Direct carotid cavernous fistulas (dCCF) involve pathologic shunting from the internal carotid artery into the cavernous sinus. We systematically reviewed the methods and outcomes of endovascular therapy for dCCF. METHODS PubMed, Scopus, and EMBASE were used to identify studies that reported outcomes for patients undergoing embolization of dCCF. Outcomes included rates of occlusion, complications, symptom improvement, and recurrence. Pooled rates for each outcome were obtained with random effects models. The influence of embolization method on outcomes was assessed with meta-regressions. RESULTS There were 16 studies comprising 270 patients. The mean age was 39.6 years, there were 36.3% females, and the mean follow-up was 19.7 months. Coils were the most common method of embolization (69.3%), followed by Onyx (31.1%), covered stent (22.2%), N-butyl cyanoacrylate (6.7%), and flow diversion (4.8%). The pooled overall occlusion rate was 92.1% (95% confidence interval [CI], 86.3-95.6; I2 = 29.2%). The pooled complication rate was 10.9% (95% CI, 7.3-16; I2 = 0%). Use of coils were associated with a slightly lower odds of overall complications (odds ratio, 0.98; 95% CI, 0.97-0.99) and cranial nerve palsy (odds ratio, 0.98; 95% CI, 0.97-0.99). The pooled fistula recurrence rate was 8.3% (95% CI, 4.3-15.4; I2 = 30.9%). CONCLUSIONS Endovascular therapy for dCCF is associated with high occlusion and low complication rates. Recurrence is not uncommon, highlighting the need for close follow-up.

Abstract
A carotid-cavernous sinus fistula (CCF) is an abnormal communication between the cavernous sinus and the carotid arterial system. Direct CCFs arise from a direct connection between the cavernous sinus and the cavernous portion of the internal carotid artery. Nowadays, endovascular neurosurgery has become the first-line treatment modality for direct CCFs owing to the high complete obliteration rate. However, reversal of the clinical symptoms may not always be congruous after the endovascular intervention. Herein, we present a 50-year-old patient who manifested diplopia, ophthalmoplegia, and orbital congestion after a traffic accident. He had suffered head injury with right side frontal intracranial hemorrhage 1 month before the ophthalmic presentation. He came to our department primarily because of declining vision and for the above symptoms, and was diagnosed with direct type CCF, for which he received transarterial coil embolization. Unexpectedly, he later presented with serous retinal detachment accompanied by ocular ischemic syndrome secondary to recurrent CCF 1 month after the intervention, so repeat coil embolization was performed.

Abstract
We present a transvenous embolization technique for a direct carotid-cavernous fistula through the pterygoid plexus to the cavernous sinus which only 2 cases have been previously reported in the English literature. This method is appropriate when transarterial techniques or other attempts at transvenous access have failed due to vessel tortuosity, hypoplasia, stenosis, or occlusion. A middle-aged female patient presented with progressive left exophthalmos with conjunctiva chemosis and bruit after sustaining a falling injury. Digital subtraction angiography revealed Barrow type A carotid-cavernous fistula. The drainage route passed through a distal thrombosed superior ophthalmic vein that ended deep in the orbit. No other patent venous sinuses connected to the cavernous sinus, except for a small tract of pterygoid plexus. After failure of transarterial approach and other methods of transvenous access, we attempted to superselectly access to the cavernous sinus by applying transpterygoid technique with embolization using detachable coils. The transpterygoid venous approach to accessing the cavernous sinus represents an alternative approach when other techniques fail.

Abstract
Herein, we describe a case of traumatic direct carotid cavernous fistula (DCCF) treated with target coil embolization using the combined transarterial and transvenous balloon-assisted technique. The patient was a 59-year-old woman who had been involved in a vehicular accident. She was admitted to the hospital due to chemosis and exophthalmos. Cerebral angiography revealed a shunt from the internal carotid artery (ICA) to the cavernous sinus (CS), which indicated DCCF. Thus, target coil embolization using the combined transarterial and transvenous balloon-assisted technique was performed. Angiography was performed 1 week after surgery to confirm the disappearance of DCCF. No recurrence was observed during the 1-year follow-up after treatment. Thus, target coil embolization using the combined transarterial and transvenous balloon-assisted technique is safe and effective for the treatment of traumatic DCCF.

Abstract
OBJECTIVE The purpose of the study was to investigate the treatments and outcomes of patients with traumatic carotid-cavernous sinus fistula (TCCF). METHODS All patients diagnosed with TCCF at our institution from January 2013 to December 2018 and meeting the inclusion/exclusion criteria were included in the study. RESULTS A total of 24 patients were included in this study. Of them, 21 (87.5%) were treated with detachable balloon embolization, 1 (4%) with coil embolization, 1 (4%) with balloon-assisted coil embolization, and 1 (4%) with balloon-assisted coil and glue embolization. Among the 21 patients treated with detachable balloon embolization, 10 underwent double-balloon technique embolization including double-detachable balloon embolization (n = 6) and balloon-assisted detachable balloon embolization (n = 4). The fistulas in 17 patients (17/21, 81%) were successfully occluded after the first attempt of detachable balloon embolization, while those in the remaining 4 patients were occluded after a second surgery due to TCCF recurrence or pseudoaneurysm development. Preservation of the internal carotid artery (ICA) was observed in 19 cases after the first treatment by detachable balloon embolization (19/21, 90.4%). ICA was occluded in the remaining two patients, as revealed by a complete angiographic evaluation of the circle of Willis. All patients achieved complete resolution of ocular and orbital manifestations as well as pulsatile bruit, except for three patients whose oculomotorius and/or abducens remained paralyzed during the follow-up period. CONCLUSION Although several endovascular treatment options are available for TCCF, the detachable balloon embolization is still the preferred method of TCCF, as evidenced in our study. Furthermore, double balloon technique, an improvement upon the conventional detachable balloon embolization, is extremely safe and can effectively treat patients with refractory TCCF.

Abstract
SUMMARY Carotid cavernous fistulas (CCFs) are abnormal connections between the carotid artery and the cavernous sinus. They are considered direct when there is a direct connection between the internal carotid artery and the cavernous sinus. These cases are generally traumatic. Direct CCFs are high-flow lesions, possibly related to intracranial bleeding, visual loss, corneal exposure or even fatal epistaxis. Treatment of such lesions is, thus, always recommended. The ideal treatment for direct CCF is to exclude the fistula from circulation, preserving the carotid flow. This can be attained using diverse endovascular techniques. The objective of the present article is to review the current techniques for treatment of direct CCFs, with special attention to the currently available endovascular treatment options.

Abstract
PURPOSE We report our initial experience using a detachable microvascular plug system to occlude the internal carotid artery during endovascular treatment of high-flow carotid cavernous fistula. CASE AND TECHNIQUE An 87-year-old patient was admitted for acute-onset double vision with associated right-eye ptosis. Exam revealed a pupil-sparing, partial right third cranial nerve palsy. MRI showed a carotid cavernous fistula with high-flow drainage. Digital subtraction angiography showed a high-flow, right-sided, direct carotid cavernous fistula with flow from the proximal right internal carotid artery. The ophthalmic artery, posterior communicating artery and anterior communicating arteries supplied retrograde flow to the fistula through the internal carotid artery. Obliteration of the fistula was achieved through coil embolization in combination with proximal and distal microvascular plugs (Reverse Medical, Irvine, Calif., USA). CONCLUSION The microvascular plug is a new addition to current endovascular embolization devices for the treatment of high-flow, direct carotid cavernous fistulas. This technique offers easy navigability through tortuous arteries, precise localization and immediate occlusion, which may allow shorter procedure and fluoroscopy times and increased cost-effectiveness. Larger case series are needed to support our observation.

Abstract
OBJECT
The goal of this study was to evaluate the obliteration rate of intracranial dural arteriovenous fistulas (DAVFs) in patients treated with stereotactic radiosurgery (SRS), and to compare obliteration rates between cavernous sinus (CS) and noncavernous sinus (NCS) DAVFs, and between DAVFs with and without cortical venous drainage (CVD).
METHODS
A systematic literature review was performed using PubMed. The CS DAVFs and the NCS DAVFs were categorized using the Barrow and Borden classification systems, respectively. The DAVFs were also categorized by location and by the presence of CVD. Statistical analyses of pooled data were conducted to assess complete obliteration rates in CS and NCS DAVFs, and in DAVFs with and without CVD.
RESULTS
Nineteen studies were included, comprising 729 patients harboring 743 DAVFs treated with SRS. The mean obliteration rate was 63% (95% CI 52.4%–73.6%). Complete obliteration for CS and NCS DAVFs was achieved in 73% and 58% of patients, respectively. No significant difference in obliteration rates between CS and NCS DAVFs was found (OR 1.72, 95% CI 0.66–4.46; p = 0.27). Complete obliteration in DAVFs with and without CVD was observed in 56% and 75% of patients, respectively. A significantly higher obliteration rate was observed in DAVFs without CVD compared with DAVFs with CVD (OR 2.37, 95% CI 1.07–5.28; p = 0.03).
CONCLUSIONS
Treatment with SRS offers favorable rates of DAVF obliteration with low complication rates. Patients harboring DAVFs that are refractory or not amenable to endovascular or surgical therapy may be safely and effectively treated using SRS.
