“…Most studies in literature are related with commonly used covered stent-graft deployment for peripheral steno-occlusive diseases. Zhang et al 11 reported 67% primary patency rate for PTFE-covered self-expandable stent-graft at three years, Speziale et al 16 reported 73.6% primary patency rate with a mean follow-up of 37.4 AE 29.3 months, Saxon et al 15 found it to be 73% at 12 months, and Lammer et al 17 70.9% at one year. In a meta-analysis consisting of 14 studies, Patel et al 12 came up with a 63.4% primary patency rate for PTFE-covered self-expandable stent-graft at five years.…”

Objectives To evaluate the primary patency rate at three years for the infra-aortic peripheral arterial pathologies treated with polytetrafluoroethylene-covered stent-grafts. Methods Patients treated with self-expandable polytetrafluoroethylene-covered stent-grafts for infra-aortic peripheral arterial aneurysms, pseudo-aneurysms, and arterio-venous fistulas were evaluated retrospectively. A total of 48 patients (35 male, 13 female; mean age: 53.8 ± 13.5) were included with 29.0 ± 16.5 months (median 27, range 4–70) mean follow-up period. The primary objective was to determine the primary patency rate at three years. The secondary objectives were to compare type and localization of pathology, and length and diameter of the stent-grafts with primary patency rate. Kaplan–Meier test was used as the main statistical method. Results Overall mean primary patency rate at three years was 77.10%. Polytetrafluoroethylene-covered stent-graft implantation in aneurysms had worse primary patency rate than pseudo-aneurysms and arterio-venous fistulas (66.6%, P = 0.03; 76.9%, P = 0.03; 88.2%, P = 0.01, respectively). Stent-graft location, length, and diameter are not associated with primary patency rate ( P > 0.05) but stent diameter is associated with better primary assisted and secondary patency rates ( P < 0.05). Conclusions Pathology of the lesion is associated with the long-term primary patency rate of polytetrafluoroethylene-covered stent-grafts but not the stent-graft location, length, or diameter. Stent diameter is associated with primary assisted and secondary patency rates.

“…It is ideal for patients with multiple comorbidities and patients who have contraindications to general or spinal anesthesia. 11 Primary stenting of acutely thrombosed PAAs is feasible and can represent an alternative solution to classic open PAA repair approaches. 12 The introduction of perioperative thrombolysis allows successful restoration of patency to the popliteal and tibial vessels.…”

We present a case of failed popliteal artery aneurysm repair using a Viabahn stent graft (W. L. Gore & Associates, Flagstaff, Ariz) due to laminated thrombus formation. A 75-year-old man presented with a symptomatic popliteal artery aneurysm. He was treated with a Viabahn stent graft. On follow-up, the patient complained of lower extremity claudication, and duplex ultrasound examination showed a focal intrastent stenosis. A computed tomography scan showed a significant stenosis within the stent graft, at the level of the knee joint creases. The patient underwent superficial femoral artery to distal popliteal surgery. This case report aims to expand on the mechanism of stent graft failure in popliteal aneurysms.

“…There are, however, very few data from randomized studies comparing the two treatments, and most single-center series rarely reported a follow-up duration >5 years. [16][17][18][19] Recently, Speziale et al 20 reported 73% primary patency at 5 years in 53 patients treated with endovascular repair. Similarly, in another recent Italian multicenter study, 5 in which our institution was also involved, the results of endovascular exclusion of PAA at 4 years were similar to those achieved with open surgery in the present series at 13 years of follow-up.…”
