1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Purpose The Apollo Onyx Delivery Microcatheter (Ev3, Irvine, CA) is a detachable-tip microcatheter that was developed to reduce the risk of microcatheter entrapment during ethylene-vinyl alcohol copolymer (Onyx) embolizations. We report our experience with the microcatheter in a variety of neurointerventional procedures. Methods We retrospectively reviewed all Onyx embolizations performed in the head, neck, and spine using the Apollo Onyx Delivery Microcatheter from its introduction at our institution in July 2014 to August 2016. Information regarding patient diagnoses, procedural details, as well as clinical outcomes were obtained from the electronic medical record, procedure reports, and relevant angiographic imaging. Results A total of 58 arterial pedicle Onyx embolizations were performed in 37 patients. There were no cases of microcatheter entrapment, early/inadvertent tip detachment, or vessel injury upon removal of the device. There were two instances (3.5%) of leakage of Onyx from the microcatheter detachment site during embolization, which did not result in adverse sequelae. Clinical outcomes were excellent, with nearly all embolizations achieving the intended goal. In multivariate analysis, length of Onyx reflux along the microcatheter tip and utilization of a higher viscosity agent, Onyx 34, were significantly associated with tip detachment. Conclusion The use of the Apollo Microcatheter is both safe and effective during neurointerventional embolizations using Onyx. Leakage of liquid embolic agent from the detachment site is an infrequent technical complication that may be encountered with the device.
