Microsurgical clipping as a retreatment strategy for previously ruptured aneurysms treated with the Woven EndoBridge (WEB) device: a mono-institutional case series.

BACKGROUND: Since its approval by the US Food and Drug Administration (FDA) in 2018, the flow disruptor Woven EndoBridge (WEB) device has become increasingly popular for the endovascular treatment of unruptured and ruptured cerebral aneurysms. However, the occlusion rates seem rather low and the retreatment rates rather high compared to other treatment methods. For initially ruptured aneurysms, a retreatment rate of 13 % has been reported. A variety of retreatment strategies has been proposed; however, there is a paucity of data concerning microsurgical clipping of WEB-pretreated aneurysms, especially previously ruptured ones. Thus, we present a single-center series of five ruptured aneurysms treated with the WEB device and retreated with microsurgical clipping. METHODS: A retrospective study including all patients presenting with a ruptured aneurysm undergoing WEB treatment at our institution between 2019 and 2021 was performed. Subsequently, all patients with an aneurysm remnant or recurrence of the target aneurysm retreated with microsurgical clipping were identified. RESULTS: Overall, five patients with a ruptured aneurysm treated with WEB and retreated with microsurgical clipping were included. Besides one basilar apex aneurysm, all aneurysms were located at the anterior communicating artery (AComA) complex. All aneurysms were wide-necked with a mean dome-to-neck ratio of 1.5. Clipping was feasible and safe in all aneurysms, and complete occlusion was achieved in 4 of 5 aneurysms. CONCLUSIONS: Microsurgical clipping for initially ruptured WEB-treated aneurysms is a feasible, safe, and effective treatment method in well-selected patients.

Use of topical antipsoriatic drugs in Denmark: a nationwide drug utilization study.

BACKGROUND: The reported real-life use of prescribed topical antipsoriatic drugs is conflicting and based on heterogeneous data sources. OBJECTIVES: To describe the utilization of topical antipsoriatic drugs among patients with psoriasis in Denmark. METHODS: A drug utilization study was performed based on nationwide Danish health registry data. We identified patients who received a first-time hospital diagnosis of psoriasis and redeemed at least one topical drug prescription in the period 2005-2015 (n = 7743). Patients were followed for 3 years from the time of diagnosis. Use of topical and systemic antipsoriatic drugs was described, specified by the type of treatment. RESULTS: The total use of topical drugs was divided between corticosteroids with calcipotriol (31%), calcipotriol (6·5%), very potent corticosteroids (24%), potent corticosteroids (30%), moderate corticosteroids (7·2%) and corticosteroids with antimicrobials (1·6%). There was a 19% reduction in the overall use of topical drugs during the study period. Use increased around the time of diagnosis and the majority of patients redeemed more than two packages of topical drugs during the first year after being diagnosed. Regional differences in patients' use of topical drugs varied considerably. The distribution of use of topical drugs was uneven, with a minority of all patients (25%) using 70% of the total amount of topical treatment. There was a 70% increase in the use of methotrexate over the study period. Biologics were used by up to 6%. CONCLUSIONS: The study provides further evidence that the use of topical antipsoriatic drugs shows considerable heterogeneity over time and regional practices, and differences between patients.
