This is a case demonstrating a combined traumatic lesion of the internal carotid artery (dissection and a carotid cavernous fistula [CCF]) in a patient who was beaten during a robbery and, while trying to escape, was hit by a vehicle. Endovascular approach for the treatment was chosen using the retrograde access from the vertebral artery to the cavernous sinus by posterior communicating (Pcom) artery due to the occlusion of the ipsilateral internal carotid. Because the artery access by the internal carotid was impossible, retrograde approach by vertebral artery and Pcom artery was done to treat the direct CCF. A patient presented with left hemiplegia and proptosis, chemosis, right eye ptosis. Computed tomography (CT) and CT angiography revealed a CCF of the right carotid. An arterial retrograde endovascular approach by the vertebral artery was used for CCF occlusion with coils. We present a rare case of a combined traumatic cerebrovascular lesion, right carotid artery dissection and a right direct CCF treated by a retrograde endovascular approach by the vertebral artery through the Pcom artery to reach the fistula point and achieved a complete cure of the CCF.

INTRODUCTION

As a rare condition, the traumatic carotid cavernous fistula (CCF) has an incidence lower than 0.2%. Another rare presentation is the cervical artery dissection after blunt trauma, with an incidence of 0.1%2) and a high mortality rate. According to Barrow et al.,1) the CCF can be classified into direct and indirect types. They also divided it into 4 subtypes categories (A-D). The shear stress or the acceleration-deceleration during a blunt trauma may cause a direct CCF or, in a high intense trauma, a completely transection of the artery. On the other hand, the indirect type may occur spontaneously or can be associated with Ehlers-Danlos syndrome, Osteogenesis imperfecta and other syndromes.5)7) We need to know that the intracranial hemorrhagic risk of direct CCF is low, and this risk may increase if: pseudoaneurysms, outflow pathways thrombosis, large varix of the cavernous sinus and drainage into cortical veins9) are present. All patients need a neuroimaging investigation with computed tomography angiography (CTA) and magnetic resonance angiography (MRA) if CCF is suspected. The gold standard for classification and diagnosis is the digital subtraction angiography (DSA). When we compare the sensitivity between MRA and CTA, the result has higher chances for the diagnosis of CCF.3)
Due to the most recent technique evolution, the endovascular technique is the first option approach for CCF treatment. The internal carotid artery (ICA) sacrifice is left as the last choice because of higher chances of cerebral ischemia when compared to other treatment techniques.8) Transarterial approach by the ICA is the most used to direct CCF treatment, however, in this case it was not possible due to occlusion of ICA caused by artery dissection. Another treatment option would be the transvenous approach if arterial access is not feasible. Endovascular approach is the first option because it has high rates of cure and low rates of complications as it is demonstrated in many reports.6)10)11)13)


CASE REPORT

A patient in the fifth decade of life was beaten during a robbery and, while trying to escape, was hit by a vehicle. Admitted in the emergency room with left hemiplegia, right eyelid drop and swollen, chemosis, proptosis and ophthalmoplegia of the right eye. CTA revealed a direct CCF with dissection of the right ICA. DSA was indicated to better understand the anatomy and to treat the lesion. DSA showed a dissection in the right cervical ICA after the bulb with no flow beyond the dissection to the intracranial territory (Fig. 1). Right ECA injection with no communication to the cavernous sinus or anastomosis to the right ICA. Right vertebral injection was visualized and a good right posterior communicating (Pcom) artery that fills the fistula and the ICA bifurcation with a slow flow to the right middle cerebral artery (MCA) territory (Fig. 2). During the left ICA, a slight communication through anterior communicating (Acom) artery and the right territory.
Patient under general anesthesia and a 6 F sheath was placed in the right femoral artery. A 6 F guiding catheter (Guider Soft tip [Boston Scientific, Fremont, CA, USA]) was positioned in the right vertebral artery. Through the guiding catheter a microcatheter Echelon 10 (Ev3, Irvine, CA, USA) with a Transend 0.014 Platinum guidewire (Stryker, CA, USA) was advanced through the Pcom artery to achieve the fistular point in the cavernous segment of the right ICA (Fig. 3). We started to deploy 2 Target coils (Stryker, CA, USA) in the cavernous sinus and after that, we gently pullbacked the microcatheter into the fistula point and 8 Target Coils was detached to occlude the fistula point and the ICA beyond the ophthalmic artery (Fig. 3). Angiography demonstrated exclusion of the fistula and normal flow by the Pcom artery to the intracranial segments of the right ICA (Fig. 4). DSA control by the left ICA showed the same flow to the right territory.


DISCUSSION

An endovascular approach is the first treatment option for direct CCF, with wide variety approach types: transarterial, transvenous and retrograde. In this case, the most common arterial approach was not feasible due to the occlusion of the ipsilateral ICA. With a dissected carotid artery, the recanalization could be done to reach the cavernous sinus and this has already been described. This approach is an option to avoid vasospasm during manipulation of Pcom or Acom arteries15) when retrograde catheterization, mainly in young patients, can be dangerous. Because accessing the cavernous sinus and the fistula point through the venous route might be difficult, the retrograde arterial access was chosen as treatment. Few reports in the literature using the retrograde approach to direct CCF4)14) are seen. All approaches may be acceptable in direct CCF, and the fastest but the least dangerous to the treatment was chosen.
Transarterial approach is the mainstay of endovascular treatment. In some countries the detachable balloon is the first choice, but occasionally, technical problems have been faced and the balloon had to be removed. Thus, the use of coils or other material as the main endovascular approach is indicated. For indirect CCF, the transvenous approach became the preferred method, especially in cases with no arterial access. It is widely used with low rates of complications and high rates of treatment success (80%).12) Trans arterial approach is also possible in indirect CCF. The retrograde approach used in this case report should be the last option if some of the other approaches are feasible.
One of the most important tips-and-tricks for endovascular approach is to well recognize the fistula point and to close this hole with coils to avoid any minimal residual fistula. We started the deployment of coils inside of the cavernous sinus and after that, with gentle manipulated the microcatheter and coils to deploy some coils inside of the fistula and then, we finished it with coils inside of the ICA beyond the ophthalmic artery.
Vertebral artery injections demonstrated completely occlusion of the fistula, with anterograde flow normalization into the right MCA and ACA. After that, the guiding catheter was withdrawn from the vertebral artery and it was positioned in the left ICA to confirm the fistula occlusion and to have a better flow by the Acom artery to the right hemisphere.


CONCLUSIONS

We present a rare case of a combined traumatic cerebrovascular lesion, right carotid artery dissection and a right direct CCF treated by a retrograde endovascular approach by the vertebral artery through the Pcom artery to reach the fistula point and a complete cure of the CCF was achieved. The patient exhibited a minor neurological improvement of the left hemiplegia after the treatment.
