Geniculate artery embolization for recurrent postarthroplasty hemarthrosis of the knee

Moses Azubuike et al. Radiol Case Rep. .

Abstract

Hemarthrosis after total knee arthroplasty is an uncommon condition. We present a unique case of recurrent hemarthrosis in a 93-year-old woman two years after an uneventful total knee arthroplasty and describe how we successfully treated her with selective angiographic embolization of the geniculate arteries.

(A) Digital subtraction angiography (DSA) of the left popliteal artery shows significant vascularity of the left lateral knee via the left superior lateral geniculate and left inferior lateral geniculate arteries (upper and lower arrows, respectively). (B) Arterial delayed-phase image shows significant staining of the left lateral synovium.

Final DSA of the left popliteal artery shows dramatic reduction in left lateral synovial vascularity, with significantly decreased flow in the left superior lateral geniculate artery. The left inferior lateral geniculate artery is no longer visualized.
