Short-term follow-up of embolization of hip synovitis

Abstract

Background: Osteoarthritis (OA) is the most frequent joint disease, affecting 10% of men and 18% of women older than 60 years worldwide. Traditionally, treatment is based in pain management with joint replacement of end-stage disease. In this setting, transcatheter embolization has emerged as an alternative in reduction of pain in patients with OA. Case presentation: A 77 years-old female presenting with two previous deep vein thrombosis and 10 years of hip pain. Magnetic resonance demonstrated a focal area of enhanced pericapsular signal near the superolateral margin of the acetabulum. Embolization of branches of the ascending branch of the lateral femoral circumflex artery was performed, with decrease of the pain and improvement in the image and her walking ability in a four-month follow-up. Conclusion: This case report have shown that embolization of hip synovitis is feasible with early clinical success, in tune with the findings of genicular and shoulder embolization. Studies with more patients and long-term results are necessary to corroborate this finding. Level of evidence: 4
