Safety and Efficacy Analysis of Stent-assisted Coil Embolization in the Treatment of Acute Ruptured Intracranial Aneurysms in the Perioperative Period.

28. Juni 2026 aktualisiert von: Tang-Du Hospital
To determine the perioperative safety and efficacy of stent-assisted coil embolization of intracranial aneurysms in the acute phase. Intravenous antiplatelet drugs that are clinically easy to administer, have good reproducibility and good controllability are used.The program focuses on exploring the safety of emergency stent-assisted embolization of intracranial wide carotid aneurysms, and then determines the effectiveness of treatment in preventing rebleeding and preventing aneurysm recurrence in the long term.

Studienübersicht

Detaillierte Beschreibung

Based on the current clinical research results and existing clinical needs, this paper conducts a study on how to carry out stent-assisted embolization of ruptured aneurysms in the acute stage, aiming to explore the safety and embolization effect of stent-assisted embolization aneurysms in the acute stage under the protection of intravenous antiplatelet drugs, focusing on the probability of complications and related clinical consequences in the perioperative period. Thus, it provides a reasonable, safe and effective interventional treatment plan for a large number of patients with ruptured aneurysms who need interventional treatment in clinical practice.

Study endpoints:

Main endpoints: 1. Complications related to surgical treatment; 2. New stent-related (possibly related) ischemic events and bleeding events within 30 days after surgery. 3. Perioperative-related mortality rate (death from any cause and Neurological dysfunction with NIHSS greater than 4 points due to complications)

Secondary study endpoints: 1. Degree of embolism immediately after surgery (R grade); 2. 30-day patient mRS score; 3. The degree of aneurysm embolism at 1 year after surgery; 4. New treatment-related ischemia and bleeding events 30 days to 1 year after thrombosis; 4. Proportion of restenosis within the stent at 1 year; 5 mRS score at 1 year postoperatively.

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Number of participants with imaging-confirmed stent-related stroke within 30 days post-procedure
Zeitfenster: From the procedure to 30 days post-procedure
Stroke was defined as an acute neurological deficit lasting >24 hours or resulting in death, with corresponding neuroimaging evidence. Events were adjudicated as stent-related by the independent clinical events committee. Confirmation required head CT, MRI, or DSA performed from the time of procedure completion to postoperative day 30. The number of participants experiencing such events was reported.
From the procedure to 30 days post-procedure
Number of participants with perioperative NIHSS score ≥4 or all-cause mortality.
Zeitfenster: from the start of the procedure to postoperative day 30.
Perioperative period is defined as the time from the start of the procedure to postoperative day 30. The number of participants with a National Institutes of Health Stroke Scale (NIHSS) score of 4 or higher at any time during this period, or death from any cause during this period, was reported. NIHSS is a 15-item neurological examination scale used to evaluate the severity of stroke, with scores ranging from 0 to 42; higher scores indicate greater severity.
from the start of the procedure to postoperative day 30.

Proportion of in-stent restenosis at 1 year post-procedure
Zeitfenster: At 1 year post-procedure
All patients underwent repeat pan-cerebral DSA at 1 year post-procedure; the degree of stenosis at the stent-implantation site was graded on the angiogram as mild (<50%), moderate (50%-70%), or severe (≥70%), and the proportion of patients with any degree of stenosis relative to the total cohort was calculated.
At 1 year post-procedure
mRS score at 1 year post-procedure
Zeitfenster: At 1 year post-procedure
The mRS score at the 1-year post-procedure cerebral angiography visit was assessed; if the patient could not attend, the score was obtained via outpatient clinic or structured telephone interview.
