Predictors of aneurysm occlusion following treatment with the WEB device: systematic review and case series

The Woven EndoBridge (WEB) device is becoming increasingly popular for treatment of wide-neck aneurysms. As experience with this device grows, it is important to identify factors associated with occlusion following WEB treatment to guide decision making and screen patients at high risk for recurrence. The aim of this study was to identify factors associated with adequate aneurysm occlusion following WEB device treatment in the neurosurgical literature and in our case series. A systematic review of the present literature was conducted to identify studies related to the prediction of WEB device occlusion. In addition, a retrospective review of our institutional data for patients treated with the WEB device was performed. Demographics, aneurysm characteristics, procedural variables, and 6-month follow-up angiographic outcomes were recorded. Seven articles totaling 450 patients with 456 aneurysms fit our criteria. Factors in the literature associated with inadequate occlusion included larger size, increased neck width, partial intrasaccular thrombosis, irregular shape, and tobacco use. Our retrospective review identified 43 patients with 45 aneurysms. A total of 91.1% of our patients achieved adequate occlusion at a mean follow-up time of 7.32 months. Increasing degree of contrast stasis after WEB placement on the post-deployment angiogram was significantly associated with adequate occlusion on follow-up angiogram (p?=?0.005) and with Raymond-Roy classification (p?=?0.048), but not with retreatment (p?=?0.617). In our systematic review and case series totaling 450 patients with 456 aneurysms, contrast stasis on post-deployment angiogram was identified as a predictor of adequate aneurysm occlusion, while morphological characteristics such as larger size and wide neck negatively impact occlusion.

     

A Team-Based Approach to Introduce and Sustain the Use of the WHO Surgical Safety Checklist in Tanzania

Introduction

Millions of patients worldwide suffer disability and death due to complications related to surgery. Many of these complications can be reduced by the use of the World Health Organization (WHO) Surgical Safety Checklist (SSC), a simple tool that can enhance teamwork and communication and improve patient safety. Despite the evidence on benefits of its use, introducing and sustaining the use of the checklist are challenging. We present a team-based approach employed in a low-resource setting in Tanzania, which resulted in high checklist utilization and compliance rates.

Methods

We reviewed reported data from facility registers supplemented by direct observation data by mentors to evaluate the use of the WHO SSC across 40 health facilities in two regions of Tanzania between January and December 2018. We analyzed the self-reported monthly data on total number of major surgeries performed and proportion of surgeries where the checklist was used. We also analyzed the use of the SSC during direct observation by external mentors and completion rates of the SSC in a random selection of patient files during two mentorship visits between June and December 2018.

Results

During the review period, the average self-reported checklist utilization rate was 79.3% (11,564 out of 14,580 major surgeries). SSC utilization increased from 0% at baseline in January 2018 to 98% in December 2018. The proportion of checklists that were completely and correctly filled out increased between the two mentor visits from 82.1 to 92.8%, but the gain was significantly greater at health centers than at hospitals (p < 0.05). Health centers (which had one or two surgical teams) self-reported a higher checklist utilization rate than hospitals (which had multiple surgical teams), i.e., 99.4% vs 68.8% (p < 0.05).

Conclusion and recommendations

Our findings suggest that Surgical Safety Checklist implementation is feasible even in lower-resource settings. The self-reported SSC utilization rate is higher than reported in other similar settings. We attribute this finding to the team-based approach employed and the ongoing regular mentorship. We recommend use of this approach to scale-up checklist use in other regions in the country as recommended in the Ministry of Health of Tanzania’s National Surgical, Obstetric, and Anesthesia Plan (NSOAP).
