Abstract:
Objective To present our single-center experience in treating traumatic direct carotidcavemous fistulas (TDCCFs)by using detachable balloon,coil and Willis covered stent via arterial route.Methods During the last five years,transarterial endovascular treatment by using detachable balloon,coil and Willis covered stent was performed in fifty-one consecutive patients of traumatic direct carotid-cavernous fistulas.with a total of 54 TDCCFs.The detachable balloon was the material of first choice,while Willis covered stents and coils were regarded as the back-up materials.A clinical and angiographic follow-up for 348 months (mean 20.8 months) was conducted to evaluate the arterial patency and the stability of embolization.The clinical data were retrospectively analyzed.Results By using the detachable balloon alone via transarterial route.85%TDCCFs were successfully treated with good preservation of ICA.A total of 98% TDCCFs in this study were successfully treated by using detachable balloon,coil and/or Willis coveted stent,the fistulas became occluded,and ICAs were preserved except one patient.Forty TDCCFs were treated with detachable balloons alone,two TDCCFs with the Willis covered stent alone,and one DCCF with coils alone.Eight TDCCFs were treated with detachable balloons together with Willis covered stent.Of these eight TDCCFs,two were treated with a single session,three were treated with detachable halloons in combination with coils,and one had to receive Willis covered stent.Second and third times of endovascular treatment were needed in 12 TDCCFs.The TDCCF-rel(at)ed symptoms were gradually relived or improved within 1 day to 6 months after treatment,except for five patients who suffered from ipsilateral moderate visual loss or cranial nerve deficit.No perioperative complications.such as vessel rupture,distal embolization or new neurologic deficits,occurred.During the follow-up period lasting for six months,neither delayed neurologic or vascular complications nor recurrence of the lesions developed.Conclusion Via the transarterial route,using detachable balloon to occlude the fistula and at the same time to preserve ICA remains the optimal treatment for TDCCFs.When the standard treatment fails.various coils and the Willis covered stents can be used as an effective alternative or remedial tool in the treatment of TDCCFs,which can preserve ICA.Willis covered stent deployment seems to be an effective,safe,feasible and economical endovasculal treatment for TDCCF,but more clinical studies are needed before we can further clarify its specifications and indications.
