(b) Angiography shows occlusion of the popliteal artery. (c) Arteriogram after mechanical thrombectomy using a Rotarex device and (d) recanalization of the popliteal artery after the deployment of a Supera stent.

case_images: At that time, his left popliteal artery thrombosis (P1 and P2 segments) was treated with mechanical thrombectomy using a 6-French (6 F) Rotarex catheter (Straub Medical, Wangs, Switzerland) and implantation of a 6.5- x 100-mm Supera stent (Figure 1).

case_images: Popliteal artery re-occlusion associated with a fracture of the Supera stent. (a) An axial image of computed tomography angiography shows left popliteal artery occlusion and a Supera stent fracture. (b) A maximum intensity projection image of computed tomography angiography shows popliteal artery thrombosis and a Supera stent fracture (arrows). (c) Anteroposterior radiogram of the Supera stent immediately after implantation (between the white arrows) and a radiographic image of the same stent at 5 months after the procedure (between the black arrows). A radiogram of the Supera stent taken immediately after implantation shows moderate elongation (white arrowhead) of the stent segment within the P2 segment of the popliteal artery. The 5-month follow-up radiogram shows a fracture of the Supera stent (black arrowhead). (d) Anteroposterior projection diagnostic angiogram. (e) Deployment of a new Supera stent for popliteal artery re-occlusion and (f) final angiogram after the implantation of a new Supera stent.

case_images: CTA showed an occlusion of the distal superficial femoral artery and popliteal artery associated with the stent fracture (Figure 2(a) and (b)). F introducer was placed in the left common femoral artery under local anesthesia. Femoropopliteal artery angiography showed an occlusion of the distal superficial femoral artery and popliteal artery associated with the stent fracture (Figure 2(c) and (d)). After mechanical thrombectomy, a new 6.5 x 150-mm Supera stent was implanted (Figure 2(e)). Admiral Xtreme 6 x 40-mm balloon catheter (Medtronic, Minneapolis, MN, United States) before the Supera stent re-implantation. A completion angiogram showed good patency of the stent (Figure 2(f)).

case_images: Repeated Supera stent fracture and re-occlusion of the popliteal artery. (a) A computed tomography angiography image shows left popliteal artery occlusion. (b) A repeated fracture of the Supera stent can be seen on a maximum intensity projection image of computed tomography angiography. (c) An anteroposterior radiograph of the left knee shows repeated stent fracture at the previous fracture site. (d) Lateral radiograph of the left knee and (e) computed tomography angiography image after bypass surgery.

case_images: CTA showed popliteal artery re-occlusion associated with a repeated fracture of the Supera stent (Figure 3(a) and (b)). Radiographs showed stent fracture at the previous fracture site (Figure 3(c) and (d)). At a 6-month follow-up, the patient was asymptomatic and CTA showed a patent graft (Figure 3(e)).
