          Abstract

          A 66-year-old woman presented with intermittent paraparesis and generalized tonic-clonic seizure. Cerebral angiography demonstrated dural arteriovenous fistula (AVF) involving superior sagittal sinus (SSS), which was associated with SSS occlusion on the posterior one third. The dural AVF was fed by bilateral middle meningeal arteries (MMAs), superficial temporal arteries (STAs) and occipital arteries with marked retrograde cortical venous reflux. Transfemoral arterial Onyx embolization was performed through right MMA and STA, but it was not successful, which resulted in partial obliteration of dural AVF because of tortuous MMA preventing the microcatheter from reaching the fistula closely enough. Second procedure was performed through left MMA accessed by direct MMA puncture following small decortications of cranium overlying the MMA using diamond drill one week later. Microcatheter could be located far distally to the fistula through 5 F sheath placed into the MMA and complete obliteration of dural AVF was achieved using 3.9 cc of Onyx.

          Treatment of intracranial dural arteriovenous fistulas: current strategies based on location and hemodynamics, and alternative techniques of transcatheter embolization.

          Intracranial dural arteriovenous fistulas (AVFs) can occur anywhere within the dura mater. Patients may be clinically asymptomatic or may experience symptoms ranging from mild symptoms to fatal hemorrhage, depending on the location (eg, cavernous sinus, transverse-sigmoid sinus, tentorium, superior sagittal sinus, anterior fossa) and venous drainage pattern of the AVF. In the past, dural AVFs have been treated with a variety of approaches, including surgical resection, venous clipping, transcatheter embolization, radiation therapy, or a combination of these treatments. Recent developments in catheter intervention now allow most patients to be cured with transcatheter embolization, although stereotactic radiation therapy is demonstrating good results in an increasing number of cases and surgery is still the preferred option in some cases. Familiarity with drainage patterns, the risk of aggressive symptoms, recent technical advances, and current treatment strategies is essential for the treatment of intracranial dural AVFs.

            Surgical treatment of high-risk intracranial dural arteriovenous fistulae: clinical outcomes and avoidance of complications.

            An increasing number of intracranial dural arteriovenous fistulae (DAVFs) are amenable to endovascular treatment. However, a subset of patients with high-risk lesions requires surgical intervention for complete obliteration. We reviewed our experience with the surgical management of high-risk intracranial DAVFs and offer recommendations to minimize complications based on fistula location and type. Hospital records for 53 patients (16 women, 37 men) with high-risk intracranial DAVFs treated surgically between 1995 and 2004 were reviewed to determine their presenting symptoms, location, endovascular and surgical interventions, angiographic outcome, and treatment complications. Most patients (76%) presented with intracranial hemorrhage, progressive neurological deficits, or seizures. All patients had high-risk angiographic features such as cortical venous drainage or venous varix. Preoperative embolization was performed in 27 patients. Surgical approaches were tailored to the lesion location. Fistulae were located in the transverse-sigmoid junction (n = 18), tentorium (n = 17), ethmoid (n = 7), superior sagittal sinus (n = 6), torcula (n = 4), and sphenoparietal sinus (n = 3). At the time of the last follow-up evaluation, 49 patients (92%) had good or excellent outcomes (Glasgow Outcome Scale score, 4 or 5) and three (6%) were deceased. Five patients had a residual fistula. One residual spontaneously thrombosed, one was treated with gamma knife radiosurgery, and two were successfully embolized. The overall morbidity and mortality rate was 13%. Despite fulminant presenting symptoms, high-risk intracranial DAVFs can be successfully managed with good outcomes. When anatomic features prevent endovascular access, or embolization fails to obliterate the lesion, urgent surgical treatment is indicated. Patients with residual filling of the DAVF should be considered for adjuvant therapy, including further embolization or radiosurgery.

              Transcranial approach for venous embolization of dural arteriovenous fistulas.

              Transvenous embolization is effective in the treatment of an intracranial dural arteriovenous fistula (DAVF). Access to the fistula via the internal jugular vein (IJV) may be limited by associated dural sinus thrombosis; a transcranial approach has been developed for venous embolization in such a situation. The authors report their experiences with the use of a transcranial approach for venous embolization of DAVFs. Ten patients with DAVFs underwent craniectomy and embolization procedures in which direct sinus puncture was performed. The DAVFs were located inside the dura mater that constituted the walls of the transverse sinus in five cases, the superior sagittal sinus in four cases, and the superior petrosal sinus in one case. All DAVFs drained directly into a sinus with secondary reflux into leptomeningeal veins. In all cases, the fistula could not be accessed from the IJVs. Craniectomy was performed in an operating room and, in seven cases, subsequent enlargement of the craniectomy was required. Sinus catheterization was performed after the patient had been transferred to the angiography room. The DAVFs were embolized using coils only in five patients, glue only in two patients, and both coils and glue in three patients. Angiographic confirmation that embolization of the fistula was successful was obtained in all cases. A transient complication occurred during the first case after sinus catheterization was attempted in the operating room. The transcranial approach allows straightforward access to DAVFs located on superficial dural sinuses that are inaccessible from the IJVs. The effectiveness of this approach is similar to that of the standard retrograde venous approach. The correct location and adequate extent of the craniectomy are essential for success to be achieved using this technique.
