The WEB device is a recent intrasaccular flow disruption technique developed for the treatment of wide-necked intracranial aneurysms. To date, a single report on the WEB Single-Layer (SL) treatment of intracranial aneurysms has been published with 1-months' safety results. The aim of this study is to report our experience and 6-month clinical and angiographic follow-up of endovascular treatment of wide-neck aneurysm with the WEB SL. ⋯ From this preliminary study, treatment of bifurcation intracranial aneurysms using WEB SL is feasible. WEB SL treatment seems safe at 6 months; however, the rate of neck remnants is not negligible due to compression of the WEB SL. Further technical improvements may be needed in order to ameliorate the occlusion in the WEB SL treatment.

Case Reports
Endovascular treatment of an infected pseudoaneurysm secondary to retropharyngeal abscess in a child.
We describe a rare case of carotid pseudoaneurysm secondary to a retropharyngeal abscess, treated with coil embolization in a 2-year-old boy. The patient presented to an emergency department with symptoms suggesting meningitis but was subsequently diagnosed with streptococcal pharyngitis. He was discharged home on oral antibiotics after a short hospitalization. ⋯ Post-treatment imaging demonstrated complete thrombosis of the pseudoaneurysm but also demonstrated acute strokes in the left MCA/ACA watershed distribution. His parents noted that the patient was clumsier and exhibited some mild speech changes and a steppage gait prior to evaluation in the ED; therefore, these were thought to be secondary to emboli from partial thrombosis of the pseudoaneurysm prior to treatment. The patient was discharged home in good condition and his neurological function improved.

Craniopagus-type conjoined twins (joined at the head) are exceedingly rare. Separation of craniopagus conjoined twins is a challenging task mainly owing to complex vascular anatomy and limited experience with this disorder. ⋯ We report a case in which endovascular techniques have been used in the separation of craniopagus conjoined twins. To our knowledge there are no reports of successful incorporation of neurointerventional methods in the disconnection of shared venous channels.

Pulsatile tinnitus of vascular origin may arise in arterial or venous structures. Many authors have reported the association of pulsatile tinnitus with anomalies of dural venous sinuses and the jugular bulb. ⋯ She was treated with dural sinus stenting and selective embolization of the diverticulum. In addition, we performed a literature review aiming to identify possible risk factors for developing the symptoms, as well as the safety and results of endovascular treatment.

Review Case Reports
Usefulness of interventional embolization of the middle meningeal artery for recurrent chronic subdural hematoma: Five cases and a review of the literature.
Although several strategies against recurrent chronic subdural hematoma (CSDH) have been proposed, no consensus has been established. Recently, middle meningeal artery (MMA) embolization has been proposed as radical treatment for recurrent CSDH. We wanted to estimate the usefulness of MMA embolization for recurrent CSDH. ⋯ MMA embolization with careful attention paid to the procedure might be a treatment of choice for recurrent CSDH.
