Analysis of the efficacy and factors affecting the prognosis of intracranial dissecting aneurysm treated with multi-stent overlap technique.

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.
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
objectiveThe study aims to identify characteristics that impact the postoperative prognosis and recurrence of intracranial dissecting aneurysms (IDA) patients treated using multi-stent overlapping techniques.
methodsClinical data from 69 IDA patients treated with multistate-assisted spring coil embolization at the hospital between January 2017 and October 2023 were retrospectively reviewed, including clinical and imaging data gathered at admission and discharge. The prognosis was determined based on mRS grade at discharge, and the patients were divided into excellent prognosis (mRS 0-2 points) and poor prognosis (mRS 3-6 points). They were split into two groups: recurrence and no-recurrence, based on whether the patients had recurrence during surgical follow-up. The patient's clinical information and aneurysm data were compared between the two groups to better understand the efficacy of multi-stenting for IDA and to investigate the factors that influence the good or negative prognosis of multi-stenting for IDA and recurrence.
resultsThe prognosis was poor in 10 patients, 7 of whom died, while 59 had an excellent prognosis. Hunt-Hess classification (χ2 = 25.503a, P = < 0.01), hospitalization days (t=-3.873, P < 0.01), operation time (t=-1.970, P = 0.049), and aneurysm height (t=-1.969, P = 0.049) were all significant. 62 patients were discharged with 4 postoperative recurrences and 58 without recurrences in patients treated with multiple stents, with significant differences in the largest diameter (t=-2.235, P = 0.025), basal length (t=-2.149, P = 0.032), and position(located in pica base or not ) (χ2 = 10.955a, P = 0.001). The postoperative recurrence rate was 5.8%, but 85.8% reported satisfactory neurologic function (mRS ≤ 2). The case fatality rate was 10.1%.
conclusionHunt-Hess grading on admission, aneurysm high, and operation time affect the prognosis of IDA, Hunt-Hess grade was an independent risk factor for prognosis. Aneurysm size, longest diameter, basal length, and location at the base of the pica affect recurrence. Located in pica base by the dissecting aneurysm is an independent risk factor for recurrence.
