Good Treatment Option

We demonstrate feasibility of implantation of a self-expanding interwoven nitinol stent in a claudicant, where recanalization attempt of a heavily calcified, occluded superficial femoral artery (TASC D lesion) was complicated by a previously implanted, fractured standard stent. Wire passage through the occlusion and beyond the fractured stent could only be achieved through the subintimal space. A dedicated reentry device was used to allow distal wire entry into the true lumen at the level of the popliteal artery. Despite crushing of the fractured stent with a series of increasingly sized standard balloons, a significant recoil remainded in the area of the crushed stent. To secure patency of the femoro-popliteal artery we therefore decided to implant the novel self-expanding interwoven nitinol stent (Supera Veritas (TM), IDEV), whose unique feature is an exceptional high radial strength. Patient presented asymptomatic without any impairment of his walking capacity at three month follow up and duplex ultrasound confirmed patency of the stent. Subintimal recanalizations can be complicated by previously implanted stents, in particular in the presence of stent fracture, where intraluminal wire passage often can not be achieved. Considering the high radial strength and fracture resistance, interwoven nitinol stents represent a good treatment option in those challenging cases and they can be used to crush standard nitinol and ballonexpandable stents.

Stent Stenosis

Background: Advances in stent technology have widened the field of indications for stent treatment of femoro-popliteal artery lesions, however the use of stents in bending arterial segments is restricted because some first- and second-generation nitinol stent designs did not respond well to the mechanical forces of femoro-popliteal segments in motion which pose a substantial risk of stent fracture inducing in-stent-stenosis. New generation nitinol stents are supposed to overcome these limitations but long-term results are rare. Patients and methods: In forty-five patients (mean age 68 y, range 50 - 85) with peripheral arterial disease (TASC II A-C, Rutherford category 2 - 5) forty-six lesions of the superficial femoral artery (37) or popliteal artery (9) were treated [25 high-grade stenoses, mean length 53 mm (range 30 - 145 mm); 21 chronic total occlusions, mean length 74 mm (range 30 - 180 mm)]. 74 % of lesions were located in the mobile bending arterial segments in the distal femoral or the popliteal segment. Clinical reevaluation performed at discharge, at 6, 12, 24, and 36 months included at least the measurement of ankle-brachial index (ABI) and duplex sonography. Results: Procedural success rate was 100 %. At 6, 12, 24, and 36 months, cumulative primary patency rate was 93.5 %, 84.8 %, 80.5 %, and 74.3 % (SE<10); freedom from target lesion revascularization rate was 95.7 %, 89.2 %, 84.9 %, and 79.3 % (SE<10); Rutherford category and ABI improved in all patients and clinical success was maintained in more than 85 % of patients. Conclusions: Sustained technical and clinical success and good clinical long-term results were achieved with Misago™ nitinol stent implantation in femoro-popliteal lesions with moderate risk for in-stent-stenosis, and in the distal femoral and popliteal mobile segment.

Artery Disease

Background: Peripheral artery disease (PAD) affecting the femoropopliteal artery is treated by endovascular interventions [2, 5, 13] increasingly. Aim of the study was to evaluate mid-term efficacy and patency of long stents in the superficial femoral and popliteal artery. Patients and methods: Between September 2006 and September 2007 103 patients received 128 stents for endovascular treatment of femoropopliteal vascular stenosis or occlusion. Clinical and hemodynamic parameters were collected. Risk factors, popliteal involvement and TASC classification, were documented and evaluated. Results: Immediate outcome was satisfactory with a technical success rate of 100 %. After a mean follow-up period of 21 months, primary patency was 83.6 %. Potential risk factor analysis for restenosis and fracture demonstrated hypertension to have borderline significance (P = 0.06). In normotensive patients no restenosis occurred. Further pre-conditions, e.g. smoking, metabolic syndrome, age, gender and previous intervention did not show any influence on restenosis or stent fracture. TASC C and D lesion had similar patency rates compared to TASC A and B lesions. Most of the restenoses (13 out of 16) were observed within the first six months of follow-up. Six stent fracture were observed (4.7 %). Conclusions: Long stents had convincing results after endovascular treatment of the femoropopliteal PAD. The used stent was an efficacious endovascular tool for long athersclerotic lesions in the superficial femoral and popliteal artery. Fracture rate was low with an incidence of 4.7 %. Most restenoses occurred within the first six months so that careful follow-up would be necessary.
