What this trial studies

This longitudinal, prospective study aims to evaluate the effects of superselective embolization on patients with hereditary coagulopathies suffering from chronic synovitis due to hemarthrosis in their joints. A total of 30 subjects will undergo imaging tests, physical assessments, and quality of life evaluations at multiple time points over five years. The embolization procedure involves using spherical microparticles to achieve partial vascular stasis in the affected joints, potentially alleviating symptoms and improving joint health. The study will be conducted at the Centro de Hemofilia do Hospital das Clinicas, Faculdade de Medicina da Universidade de São Paulo.

Who should consider this trial

Good fit: Ideal candidates are individuals with hereditary coagulopathies who have chronic synovitis resulting from hemarthrosis in their elbows, knees, or ankles.

Not a fit: Patients who do not complete the planned assessments or decline to participate in the study may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this treatment could significantly improve joint function and quality of life for patients with hereditary coagulopathies.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in treating joint issues related to coagulopathies, suggesting potential for success.
