“…Beseth et al 19 reported that the short segment interposition of the prosthetic graft may decrease the thrombogenesis into the graft, and provide a good graft patency rate. This concept is supported by the study by Blanco et al 20 which reported that short segment PTFE bypasses had better graft patency than long segment PTFE bypasses for the treatment of PAAs. On the other hand,…”

Abstract:Purpose:The aim of this study was to evaluate the long-term outcomes of the surgical repair of popliteal artery aneurysms (PAAs), and to analyze the factors associated with graft patency. Methods: Between January 1980 and December 2013, forty-five limbs were subjected to open surgical repair at Tokyo Medical and Dental Hospital. We retrospectively examined the patients' clinical characteristics, clinical symptoms, and aneurysm-related anatomy. Surgical procedures were performed through a posterior or medial approach with using autologous vein or prosthetic graft. Surgical outcomes were evaluated by postoperative-mortality, postoperative-morbidity, graft patency, and limb salvage. Results: During the study period, forty-five limbs [35 patients, mean age: 60 years] were subjected to open surgical repair. 25 limbs were treated through a posterior approach with using 23 autologous vein grafts (AVGs), and 2 expanded polytetrafluoroethylene (ePTFE) grafts. The other 20 limbs were treated through a medial approach with using 13 AVGs, and 7 ePTFE grafts. During the mean follow-up period of 65 months, the primary patency rates at one, three and five years were 88.0%, 75.7% and 75.7%, respectively, and the limb salvage rates at one, three and five years were 97.1%, 91.4% and 91.4%, respectively. In the univariate analysis, the ligation and bypass grafting affected the primary patency rate significantly, and the ePTFE graft was associated with a poor primary patency in the multivariate analysis (hazard ratio: 17.8). Conclusion:The use of resection or endoaneurysmorrhaphy for PAAs and graft interposition with an AVG might be more effective for the open repair of PAAs.

At the beginning of the era of this new modality of treatment, in North America home-made devices made of balloon expandable stents covered with vein or PTFE were used, while in Europe the Cragg Endo Pro stents were used, which included the System 1 (a self expandable nitinol stent covered by polyester fabric, Cragg EndoPro System; Mintec, La Ciotat, France); the Passager stent graft (a self expandable, polyester-covered metal stent-grafts; Boston Scientific, Watertown, Mass), and the Corvita stentgraft (a metallic self-expandable, braided wire stent to which is bonded an inner liner of polycarbonate urethane microfibers; Boston Scientific, Bülach, Switzerland).…”

Endovascular repair of popliteal aneurysms

Endovascular repair is an established modality of treatment for abdominal aortic aneurysms. It is therefore reasonable to expect its application to other less common aneurysmal conditions, including isolated iliac and popliteal artery aneurysms (PAA). There are, however, essential differences between aortic aneurysms and peripheral aneurysms: smaller arterial caliber, mobility of the arterial segment, associated occlusive disease, and devices that have not been specifically designed for peripheral applications. Due to these differences, results obtained in abdominal aortic aneurysms cannot be extrapolated to peripheral aneurysms. The attraction of the endovascular repair for PAA is its minimally invasive nature. The literature, however, provides only case reports, case series and small cohorts, and one small randomized, controlled trial. A cumulative summary of these studies provides the clinician with information upon which to base the choice of treatment on a specific patient. Endovascular repair for PAA with suitable anatomy and good run-off can be considered safe, and medium term results appear comparable with those of open repair.

“…11e13 If no suitable vein conduit is available, expanded polytetrafluoroethylene (ePTFE) or polyester grafts can be used, although with a 30% lower patency compared with the venous conduit at long-term followup. 14,15 Another treatment option for PAA is endovascular repair, which provides shorter operation time, hospital stay, and less perioperative and postoperative morbidity and therefore a faster patient recovery. Most studies have shown patency rates at 4 years varying between 64% and 88%, which is comparable with the 4-year patency rate of a surgical bypass (69e88%).…”
