Objective Intra-procedural WEB device migration is a scarcely reported complication that necessitates prompt intervention. Case Presentation Endovascular treatment of two broad necked flow-related aneurysms was planned aided by WEB-SL (Woven EndoBridge-single layer) devices in a 71-year-old female with known left temporal arteriovenous malformation. Inadvertent distal migration occurred while performing a control angiogram with an automated iodine injector. Immediate retrieval was successfully performed using a Solitaire stent-retriever. Conclusion To our knowledge, we report for the first time the successful retrieval of a distally migrated WEB using a stent-retriever device.

PurposeTo evaluate the clinical and anatomical results of treatment of intracranial aneurysms (IA) with the Woven EndoBridge (WEB) device, with emphasis on mid term and long term follow-up.MethodsBetween November 2010 and November 2015, we retrospectively identified, in our prospectively maintained database, all patients treated by WEB device placement for an IA at three institutions. Clinical charts, procedural data, and angiographic results were reviewed.Results48 patients with 49 IAs were identified. There were 35 women and 13 men with a mean age of 57 years (range 35–76 years). All IA were wide necked. Mean aneurysm size was 8.6 mm. There were 44 unruptured IA and 5 ruptured IA. During endovascular treatment (EVT), adjunctive devices were used in 22.4% of procedures. A good clinical outcome (modified Rankin Scale score ≤2) was achieved in 44/48 patients (92%). There was no mortality. Mean follow-up was 25 months (range 3–72 months; median 24 months). Between mid term and long term follow-up, occlusion was stable in 19/23 IA (82.6%), improved in 2/23 IA (8.7%), and worsened in 2/23 IA (8.7%). Retreatment was performed in 8/49 IA (16.3%). At the latest available follow-up, there were 34/47 (72.3%) complete occlusions and 13/47 (27.7%) neck remnants.ConclusionsOur study suggests that EVT of IA with the WEB device provides adequate and stable long term occlusion.

Background 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. Methods Ten patients with 10 unruptured wide-necked aneurysms were prospectively enrolled in this study. Feasibility, intraoperative and postoperative complications, and outcomes were recorded. Immediate and 6-month clinical and angiographic results were evaluated. Results Failure of WEB SL placement occurred in two cases. Eight aneurysms were successfully treated using one WEB SL without additional treatment. Three middle cerebral artery, four anterior communicating artery, and one basilar artery aneurysms were treated. Average dome width was 7.5 mm (range 5.4–10.7 mm), and average neck size was 4.9 mm (range 2.6–6.5 mm). No periprocedural complication was observed, and morbi-mortality at discharge and 6 months was 0.0%. Angiographic follow-up at 6 months demonstrated complete aneurysm occlusion in 2/8 aneurysms, neck remnant in 5/8 aneurysms, and aneurysm remnant in 1/8 aneurysm. Conclusions 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.

OBJECTIVE The Woven EndoBridge (WEB) is an innovative new technique for securing cerebral aneurysms. It is designed particularly for wide-necked bifurcation aneurysms that otherwise would be difficult to treat. There is a paucity of follow-up data in the literature due to the novelty of this technique. The authors reviewed their data from cases involving patients treated at Leeds General Infirmary with the WEB device. They assessed the safety and complication risk associated with the device and clinical and radiological follow-up outcomes in their patients. This is, to their knowledge, the first publication to include the new single-layer sphere device (WEB SLS) in addition to the original dual-layer (WEB DL) and the (nonsphere) single-layer (WEB SL) devices. METHODS Data from 22 patients who underwent 25 WEB treatments were analyzed. Of the 25 WEB procedures, 3 were performed on an acute basis, 1 was performed on a semiacute basis, and the remaining 21 were elective. A novel 6-point scoring system called the Leeds WEB aneurysm occlusion scale was created to ensure accurate assessment based on the morphology of the WEB device. Outcome was assessed at follow-up by MR angiography with or without digital subtraction angiography and the modified Rankin Scale (mRS). RESULTS Deployment of the WEB device was successful in 22 (88%) of 25 procedures; 3 (12%) of the attempts at WEB treatment were abandoned. One of the patients in whom treatment was abandoned underwent a successful second attempt. Immediately after the 22 procedures with successful deployment, 4 (18%) of the patients had a complete occlusion of the aneurysm and WEB device; 10 (45%) had varying degrees of occlusion within the WEB device but no aneurysm neck or remnant; 3 (14%) had a neck remnant; and 5 (23%) had an aneurysm remnant. Of the patients with an aneurysm remnant, 1 had a complete aneurysm occlusion at ≥ 3-months follow-up. In total, 6 (27%) patients had a residual aneurysm at ≥ 3-months radiological follow-up. One of these patients was admitted with hydrocephalus secondary to a recurrent aneurysm and later received a second WEB treatment with additional coiling. Only 1 patient developed new neurological symptoms. This patient went from an mRS score of 0 to a score of 1 and had radiological evidence of a thromboembolic event. Two patients showed radiological evidence of a new thromboembolic event on follow-up MRI but were clinically asymptomatic. CONCLUSIONS The WEB has shown itself to be a promising new device with the potential to increase the scope of treatment for difficult wide-necked bifurcation aneurysms. The technique is safe, and short-term results show effective occlusion of complex aneurysms with minimal complications associated with the procedure. Long-term efficacy, however, still needs to be assessed.

The image quality of Cone Beam Computed Tomography has enough diagnostic value in differentiating between haemorrhage, embolic materials and the arteriovenous malformation nidus to facilitate physicians to decide for further management of the patient.

Abstract Objectives Recurrent pregnancy loss (RPL) is a devastating complication of pregnancy with various etiologic backgrounds. Case presentation We present a case of combined oxidative phosphorylation deficiency 3 (COXPD3) carrier pregnant woman with Methylenetetrahydrofolate reductase (MTHFR) polymorphisms. She had five pregnancy losses and a postpartum death due to COXPD3. The patient was admitted to our clinic for the first time at her seventh pregnancy with oocyte donation. The patient was registered in a special antenatal care program and delivered a healthy baby at term. Her eighth pregnancy was terminated due to COXPD3 which was prenatally diagnosed. Conclusions Comprehensive and individualized approaches are necessary in RPL cases to obtain optimal outcomes.

Abstract Background Central precocious puberty is a condition characterized by precocious activation of the hypothalamic-pituitary-gonadal axis. It may be idiopathic or secondary to organic causes, including syndromes such as Neurofibromatosis type 1 (NF1). Case presentation We presented a girl of 6 years and 10 months with almost 11 café-au-lait skin macules, without other clinical or radiological signs typical of NF1, and with a central precocious puberty. Genetic analysis evidenced the new variant NM-152594.2:c.304delAp. (Thr102Argfs*19) in SPRED1 gene, which allowed to diagnose Legius syndrome. Conclusions We report for the first time a case of central precocious puberty in a girl with Legius syndrome. The presence of central precocious puberty in a child with characteristic café-au-lait macules should suggest pediatricians to perform genetic analysis in order to reach a definitive diagnosis. Further studies on timing of puberty in patients with RASopathies are needed to better elucidate if this clinical association is casual or secondary to their clinical condition.
