Abstract
BACKGROUND: Popliteal artery entrapment syndrome (PAES) is a condition in which the popliteal artery/vein is entrapped by the gastrocnemius muscle. CASE SUMMARY: A patient presenting with intermittent claudication was diagnosed with a popliteal artery occlusion and underwent endovascular therapy. Although the occlusion recurred and an interwoven nitinol stent was implanted, a stent fracture was observed within 3 months. DISCUSSION: Recurrent popliteal artery occlusion can occur because of external compression, such as in PAES. In this case, there was significant external compression of the popliteal artery by the gastrocnemius muscle. Notably, the stent fractured early, even though the interwoven nitinol stent is known for its high compressibility, resistance to damage, and flexibility. TAKE-HOME MESSAGES: This case highlights the importance of accurately diagnosing occlusive lesions of the popliteal artery. Endovascular therapy is contraindicated in PAES because of the risk of repeated early arterial occlusion.
