Embolisation der Arteria genicularis

Combined

genicular artery embolization and genicular nerve block to treat chronic pain following total knee arthroplasty. A Frontal projection digital subtraction angiography revealed extensive hypervascular synovium supplied by branches of the genicular arteries (white arrows) at the superomedial, inferomedial, and superolateral compartments (white circles) about the total knee replacement prosthesis. B Completion angiography after genicular artery embolization demonstrated subtotal devascularization with mild residual synovial blush (white circles) at the inferomedial compartment. C Selective angiography and embolization of the articular branches of the recurrent anterior tibial artery (white arrows) supplying the lateral joint space. D Completion angiography after genicular artery embolization demonstrated total devascularization

Role of

geniculate artery embolization in the treatment of knee pain secondary to osteoarthritis. Illustrative diagram shows the classic anatomy of the genicular arteries. DGA: Descending genicular artery; (MSGA) medial superior genicular artery, (MIGA) medial inferior genicular artery, (LSGA) lateral superior genicular artery, (LIGA) lateral inferior genicular artery and (ATRA) anterior tibial recurrent artery

Role of

geniculate artery embolization in the treatment of knee pain secondary to osteoarthritis. Angiography of the descending genicular artery (blue arrow) shows hyper-vascular inflammatory “blush” (black arrow) over the medial aspect of the knee

Role of

geniculate artery embolization in the treatment of knee pain secondary to osteoarthritis. Angiography post-embolization revealed the absence of the inflammatory blush. The parent genicular artery remains patent
