Event Description

The following literature article was reviewed: "comparison of endovascular versus bypass surgery in femoro-popliteal tasc ii d lesions: a single-centre study" gian franco veraldi et al.Annals of vascular surgery accepted sep 14, 2017; published online sep 22, 2017.Https://doi.Org/10.1016/j.Avsg.2017.09.008 ann vasc surg 2018;47:179-187.Eighty limbs with symptomatic severe occlusive disease (tasc ii d) of the femoro-popliteal segment observed from january 2013 to january 2017 were included in this retrospective study.Indication to treatment was severe claudication in 17 limbs and critical limb ischemia (cli) in 63 limbs.As to the run-off, all limbs included had at least one vessel patent up to the distal third of the leg.Of these limbs, 40 were treated by means of percutaneous transluminal angioplasty (pta) plus bare metal stent (bms) (group a) and 40 were treated by means of femoro-popliteal bypass with gore® propaten® vascular graft (6 mm and 7 mm diameter) plus linton patch with biologic material (either autologous vein or cryopreserved vein homograft in case of unavailable autologous vein) tailored to the distal anastomosis (group b).Patency, re-intervention rate and limb salvage were compared in the two groups.Patients were followed with a clinical assessment and duplex at 1, 6, 12 months after procedure and then annually.A closer follow up was performed in case of any complication.In the article the following complication greater than 30 days after surgery in group b was reported: one patient underwent surgical correction of a proximal anastomotic aneurysm.
