Summary
Raymond-Roy class predicts early brain aneurysm recanalization after endovascular treatment. Patient and coil factors did not influence treatment failure, highlighting RRC as a key predictor needing further study.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Medical Imaging
Background:
- Endovascular treatment is standard for brain aneurysms.
- Early recanalization occurs in 15% of cases, necessitating re-treatment.
- Identifying risk factors for treatment failure is crucial.
Purpose of the Study:
- To investigate risk factors for early treatment failure in endovascularly treated brain aneurysms.
- To evaluate the association of patient and aneurysm characteristics with recanalization.
- To determine the predictive value of Raymond-Roy class (RRC) and coil packing density.
Main Methods:
- Retrospective cohort study of endovascularly treated aneurysms (July 2012 - Dec 2015).
- Inclusion of cases with pre- and post-treatment imaging.
- Morphologic analysis using 3D volume rendering and statistical analysis of clinical factors.
Main Results:
- 14% of 50 patients experienced early treatment failure.
- Raymond-Roy class (RRC) significantly predicted treatment failure (p=0.0052).
- Coil packing density did not correlate with aneurysm recanalization (p=0.61).
Conclusions:
- RRC is the strongest predictor of early aneurysm recanalization.
- Patient demographics, aneurysm characteristics, and coil density did not significantly impact early outcomes.
- Further research is needed to confirm RRC's predictive value and investigate late recanalization factors.

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.
