Summary
Sonography effectively quantifies peripheral arteriovenous malformations (AVM) using hemodynamic and morphological data. This aids in diagnosis, monitoring disease progression, and planning interventions for AVM.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Medical Diagnostics
Background:
- Congenital vascular malformations, including arteriovenous malformations (AVM), affect 1.5% of the population.
- Peripheral congenital AVM can cause significant hemodynamic and metabolic dysfunction.
- Accurate quantification of AVM is crucial for effective management.
Purpose of the Study:
- To evaluate the utility of sonographic parameters for quantifying peripheral congenital AVM.
- To assess functional-hemodynamic and morphological data for AVM characterization.
Main Methods:
- Sonographic examinations including continuous-wave Doppler and color-coded duplex sonography were performed on 8 patients.
- Clinical assessment, medical history, and venous occlusion plethysmography were utilized.
- Pre-intervention angiography results were used for comparison.
Main Results:
- The resistance index of Pourcelot and vascular blood flow velocities are appropriate functional-hemodynamic parameters for AVM quantification.
- Sonomorphological parameters reflect the specific vascular pathology influenced by hemodynamic changes.
- These sonographic findings correlate with pre-intervention angiography.
Conclusions:
- Functional-hemodynamic and sonomorphologic parameters enable quantification of peripheral congenital AVM.
- Sonographic assessment provides a basis for deciding on further invasive radiological diagnosis.
- This approach aids in diagnosis, disease monitoring, and pre-interventional planning.
