Osteonecrosis of femoral head occurred after stent placement of femoral artery.

Shimatani A, Inori F, Yoshida T, Tohyama M, Konishi S, Ohashi H - Case Rep Orthop (2014)

Bottom Line: We present a case of osteonecrosis of femoral head (ONFH) that occurred after stent angiography of femoral artery for the treatment of arteriosclerosis obliterans (ASO) of left inferior limb in a 76-year-old woman.No case of late collapse of femoral head as a complication of endovascular procedure such as stent placement has been previously documented.We considered that ONFH occurred after detaining stent at a junction of left deep femoral artery for the treatment of the ischemia of left lateral and medial femoral circumflex artery.

ABSTRACT
We present a case of osteonecrosis of femoral head (ONFH) that occurred after stent angiography of femoral artery for the treatment of arteriosclerosis obliterans (ASO) of left inferior limb in a 76-year-old woman. No case of late collapse of femoral head as a complication of endovascular procedure such as stent placement has been previously documented. We considered that ONFH occurred after detaining stent at a junction of left deep femoral artery for the treatment of the ischemia of left lateral and medial femoral circumflex artery.

fig2: MRI T1WI at the time of admission to our hospital. Femoral head was completely collapsed and low band was observed in the upper edge of the femoral head.

Mentions: Plain radiography showed the stent which is detained in left femoral artery, collapse of left femoral head, and disappearance of joint space (Figure 1(b)). MRI T1WI showed bone marrow edema, collapse of left femoral head with appearance of low band, and pooling of joint fluid (Figure 2). Terminal stage of coxarthrosis was diagnosed from these findings. Angiography before PTA showed complete obstruction of left femoral artery; however bloodstream for left femoral head could be identified (Figure 3(a)). Angiography taken just before THA at our hospital showed increasing of blood vessel around left hip joint (Figure 3(b)). These findings suggested compensation of the ischemia. Six months after detaining stent, THA was performed with noncemented cup and cemented stem. Macroscopic findings of the resected femoral head showed severe osteoarthritic change, such as flattening of the upper part of femoral head and osteophyte formation. From microscopic findings in high magnification field (×100), empty lacuna and addition of newly formed bones adjacent to those necrotic bone areas were observed (Figure 4). These histological findings indicated that bone necrosis occurred firstly and osteoarthritic change progressed secondarily.
