Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study sought to develop and validate a new risk stratification score (Henan predicting the risk of intracerebral hemorrhage score, Henan-PRIHS) based on intra-arterial contrast enhanced Flat Detector CT (IA-CEFDCT) to predict symptomatic intra-cerebral hemorrhage (sICH) after stroke thrombectomy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Henan-PRIHS was developed from 95 patients who underwent IA-CEFDCT and MT for acute anterior stroke. Patients were classified as having one of three grades according to the presence of contrast filling within the occluded vascular territory. Grade 0 was normal or less contrast filling in affected hemisphere, grade 1 and 2 were small and medium-large area without contrast filling, respectively. The Youden index was used to determine the optimum no contrast filling area cutoff for defining grade 1 and 2. The score was subsequently validated in a different population of 208 patients and compared with three established scores.

IA-CEFDCT group

95 patients who underwent IA-CEFDCT and MT for acute anterior stroke.

intra-arterial contrast enhanced Flat Detector CT

Intervention Type PROCEDURE

After femoral artery puncture, FDCT scan (if necessary) and IA-CEFDCT scan were performed on a single flat-detector angiography system (Allura Xper FD20, Philips Medical systems, Best, the Netherlands), respectively. FDCT was acquired with the following acquisition parameters: 20s rotation, 220° rotation, 617 single frames at a frame rate of 30/s, 48cm detector field of view, 1024 acquisition matrix. Images were reconstructed using a soft-tissue kernel with an isotropic voxel size of 0.9 × 0.9 × 0.9 mm on a dedicated workstation for FPCT data (XperCT Dual 3.2.0). For image analysis, these isotropic FDCT data were viewed in the axial plane with 5 mm slice thickness.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. age ≥18 years,
2. occlusion of internal carotid artery and/or middle cerebral artery (MCA) M1 or M2 segments confirmed by CTA or MRA or DSA,
3. baseline National Institutes of Health Stroke Scale (NIHSS) score ≥ 4 points,
4. MT was performed within 16 hours from stroke onset,
5. baseline CT scan and IA-CEFDCT scan must be performed; 24 hours post-treatment CT scan was done and when the patient's neurological state had deteriorated.

Exclusion Criteria

1. bilateral infarcts,
2. history of hemorrhagic stroke,
3. post-procedure ICH (including SAH) due to iatrogenic complications,
4. missing clinical and demographic data,
5. poor-quality IA-CEFDCT scans (i.e., motion artifact) that limited accurate identification of the region of interest. Bridge treatment (combined intravenous thrombolysis with MT) was not excluded from this study.
