A 50-year-old woman presented with headaches. Evaluation revealed an unruptured 7-mm broad-based basilar artery fenestration aneurysm that incorporated both limbs of the basilar fenestration and both distal vertebral arteries. A 4.5 mm × 22 mm Enterprise stent (Codman Neurovascular, Raynham, MA, USA) was deployed from the right limb of the basilar fenestration into the right distal vertebral artery. Similarly, a 2.5 mm × 20 mm Neuroform EZ stent (Boston Scientific, Natick, MA, USA) was placed from the left limb of the MK-8669 concentration basilar fenestration into the
left distal vertebral artery. Following stent deployment, the aneurysm was treated with coil-embolization through a jailed microcatheter. In the case presented, a double-barrel stent
configuration enabled dense coil embolization of the aneurysm as well as preservation of both basilar fenestration limbs and both distal vertebral arteries. “
“A trigeminal artery as the most common persisting embryonic carotid-basilar anastomosis is found in up to .2% of adults. In rare instances, trigeminal-cavernous fistulas develop either spontaneously or after a trauma. We present a 16-year-old patient with a traumatic trigeminal-cavernous fistula (Saltzmann type 2), which was successfully treated by interventional occlusion of the persistent trigeminal artery. After intervention, clinical symptoms (chemosis, right-temporal bruits, and sixth nerve palsy) selleck inhibitor resolved. In this case, fistula occlusion was achieved by coil embolization with only 4 coils placed directly at the rupture point of the trigeminal artery but not into
the cavernous sinus. Thus, the cavernous sinus was preserved in function and structure. Special anatomy and interventional peculiarities of this unique case are described in detail. “
“Vertebrobasilar dolichoectasia (VBD) is a dilatative arteriopathy associated with a decreased blood flow velocity. Fluid attenuated inversion recovery (FLAIR) vascular hyperintensity (FVH) is a phenomenon most likely representing slow arterial blood flow. We sought to examine the frequency and extent of FVH in VBD. We analyzed magnetic resonance imaging (MRI) findings in 77 VBD patients with special emphasis on FVH in relation to the diagnostic MRI criteria of VBD and the etiology in symptomatic patients. In 49 (63.6%) VBD patients, FVH could be detected: 上海皓元 in 22 (44.9%) a small hyperintense rim near the vessel wall (grade 1), in 20 (40.8%) a strong hyperintense rim near the vessel wall (grade 2), and in 7 (14.3%) the hyperintense signal filled the complete vessel lumen (grade 3). The diameter of the basilar artery moderately correlated with the extent of FVH. A higher FVH grade (2 and 3) was more common in patients with TIA/stroke related to VBD (9/16 [56.3%]) in comparison to patients with other etiology and asymptomatic patients (18/61 [29.5%]; P = .046). FVH may be useful to demonstrate the decreased blood flow velocity in VBD.
