Background: The etiology of a non-sinus-type dural arteriovenous fistulas (DAVFs) with shunt points located on the sinus wall, previously described as on-the-wall-type DAVFs, is unknown. Case Description: Two cases transverse DAVF point limited to causing cortical venous reflux, were successfully treated endovascular transarterial Onyx embolization. cast showed multiple feeders from occipital and middle meningeal arteries aggregated in arachnoid granulation (AG), which dilated draining vein....
Flow re-direction endoluminal device (FRED) is a novel dual-layer flow-diverting stent to treat cerebral aneurysms with high obliteration rates, however, it induces inevitable metal-related artifacts. We compared silent magnetic resonance angiography (MRA), new MRA method using ultra-short time of echo and arterial spin-labeling, conventional time-of-flight (TOF)-MRA for imaging treated FRED.Between May 2020 September 2022, 16 patients unruptured internal carotid FRED simultaneously...
Endovascular treatment of wide-necked bifurcation aneurysms remains challenging. Although the advent PulseRider and Web has expanded options, with a large deviation from parent artery axis difficult to treat. We present case aneurysm that was misaligned angle between long successfully treated Y-shaped PulseRider-assisted coil embolization.A 64-year-old woman presented an unruptured basilar tip aneurysm. Cerebral angiography showed measuring 8.1 mm × 6.1 mm, neck 5.7 mm. The strongly tilted...
