Insights
Few studies report cerebral arteriovenous malformation (cAVM) angioarchitecture using Joint Writing Group (JWG) guidelines. This systematic review found only 15% of studies adhered to JWG standards, indicating incomplete reporting of cAVM features.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Cerebral arteriovenous malformations (cAVMs) are complex vascular abnormalities.
- The Joint Writing Group (JWG) established guidelines for reporting cAVM angioarchitecture.
- The extent to which these JWG guidelines are adopted in subsequent research remains unclear.
Purpose of the Study:
- To systematically review and quantify the adherence to JWG reporting standards in publications describing cAVM angioarchitecture.
- To identify which JWG standards are utilized and if definitions or features deviate from the original guidelines.
Main Methods:
- A systematic literature search was conducted using the PRISMA checklist.
- Publications reporting on cAVM angioarchitecture were screened for adherence to JWG guidelines.
- Data were extracted on the use of JWG standards, variations in definitions, and additional reported features.
Main Results:
- Out of 4306 initially identified articles, 219 were selected for analysis (105 from database, 114 from other sources).
- Only 15% (33/219) of the selected studies specifically referenced the use of JWG standards.
- A significant gap exists in the routine, comprehensive reporting of cAVM angioarchitecture according to established guidelines.
Conclusions:
- Adoption of the JWG guidelines for reporting cAVM angioarchitecture has been limited since their publication.
- This suggests that the detailed description of cAVM angioarchitecture is not consistently performed in the scientific literature.
- Further efforts are needed to promote and ensure consistent application of standardized reporting guidelines for cAVMs.
Abstract:
A cerebral arteriovenous malformation (cAVM) is an abnormal tangle of cerebral blood vessels. The consensus document by the Joint Writing Group (JWG) highlighted which cAVM features should be recorded. Subsequent publications have reported cAVM angioarchitecture, but it is unknown if all followed the JWG recommendations. The aim of this systematic review was to describe use of the JWG guidelines. A database search, using the PRISMA checklist, was performed. We describe the proportion of publications that used JWG reporting standards, which standards were used, whether the definitions used differed from the JWG, or if any additional angiographic features were reported. Out of 4306 articles identified, 105 were selected, and a further 114 from other sources. Thirty-three studies (33/219; 15%) specifically referred to using JWG standards. Since the JWG publication, few studies have used their standards to report cAVMs. This implies that the angioarchitecture of cAVMs are not routinely fully described.
