“…The incidence of SWI, including patch infection after carotid surgery, is 0.2%-0.5% (14,15). Open abdominal aortic surgery is associated with 2.4%-6.3% risk of 30-day SWI (16) and 0.44%-1.9% risk of graft infection (17,18). In a retrospective analysis with 12,626 open abdominal aortic aneurysm reconstructions, the risk of developing graft infection was highest during first postoperative year: 32% of all graft infections developed during the first year after surgery (17).…”

Surgical wound infection is one of the most common complications after peripheral vascular surgery. it increases the affected patient's risk for major amputation as well as mortality. furthermore, surgical wound infection is an additional cost. Wound infections after vascular surgery are of multifactorial nature and generally result from the interplay of patient-and procedure-related factors. the use of systemic antibiotic prophylaxis may be the most important method in preventing surgical wound infections. in this review article, we report the current literature of surgical wound infections after peripheral vascular surgery.

Abstract:The aim of this retrospective study was to evaluate the results of vascular operations based on the RaK prostheses, with a particular attention paid to their long-term patency. The study included 105 patients who were operated on in the period from 1992 to 1996. Vascular surgery was performed in the aortofemoral area and the underlying diagnoses were Leriche syndrome, asymptomatic abdominal aortic aneurysm, iliac artery stenosis or occlusion and symptomatic abdominal aortic aneurysm. During the mean follow-up time of 96 months (range 28-144), 8 patients (7.6 %) were lost to follow-up and 23 patients (21.9 %) died. At 12, 36, 60 and 120 months after surgery, the prostheses were patent in 99 %, 98 %, 93 % and 89 % of the patients, respectively. It is concluded that the RaK collagen prosthesis is the device of high quality and parameters comparable with the other types of knitted vascular prostheses currently used (Tab. 3, Fig. 4, Ref. 17 The number of different kinds of vascular prostheses that are produced today is enormous. The basic groups are distinguished according to the production technology and, to a certain extent, to the characteristic features of the prostheses -the most frequent prostheses used in vascular surgery are knitted dacron prostheses and prostheses made of an expanded polytetrafl uorethylen (ePTFE).The wall of knitted prostheses is made of synthetic fi bres, most often polyester. The gradual development has led to a compromise between the porosity necessary for anchoring the internal layer of fi brin, which is gradually being deposited, and the possibility of an effi cient preclotting of the prosthesis. On the other hand, a disadvantage of the prostheses that are too tightly knitted is a worse healing process and more diffi cult suturing. The last stage in the development of knitted prostheses is characterised by prostheses whose walls have been impregnated with collagen, gelatine or albumin during the manufacturing process. This fact ensures wall impermeability and, therefore, a minimal blood loss during implantation. Good healing is made possible by means of the gradual absorption of an artifi cially applied collagen layer (1, 2).At the Second Department of Surgery at St. Anne´s University Hospital in Brno, vascular surgery has a long tradition and has included cooperation with the producer (Výzkumný ústav pletařský Brno, Hosiery Research Institute Brno) in the research and development of synthetic grafts. At present, knitted prostheses impregnated with collagen are applied to the whole length of the abdominal aorta and iliac arteries as far as the inguinal ligament (Fig. 1). When the run-off is suffi cient and it is not possible to use an autologous venous graft, they are also used in the femoropopliteal area above the knee joint.The aim of this retrospective study was to evaluate clinical experience with this type of vascular prosthesis and to compare some relevant parameters (especially long-term patency) with the results obtained by other researchers.

“…A randomized multicenter trial of aortoiliac reconstructions comparing PTFE to knitted Dacron showed no difference in 5-year patency by graft type. 26 In general, all commercially available prosthetic grafts perform well in this location. The limitations of prosthetic conduits in these environments relate to the potential for infection (an infrequent, although highly morbid complication), anastomotic pseudoaneurysms, and thrombosis (Tables 1 and 2).…”

The prevalence of peripheral arterial disease (PAD) is increasing worldwide, with recent global estimates exceeding 200 million people. Advanced PAD leads to a decline in ambulatory function and diminished quality of life. In its most severe form, critical limb ischemia, rest pain, and tissue necrosis are associated with high rates of limb loss, morbidity, and mortality. Revascularization of the limb plays a central role in the management of symptomatic PAD. Concomitant with advances in the pathogenesis, genetics, and medical management of PAD during the last 20 years, there has been an ongoing evolution of revascularization options. The increasing application of endovascular techniques has resulted in dramatic changes in practice patterns and has refocused the question of which patients should be offered surgical revascularization. Nonetheless, surgical therapy remains a cornerstone of management for advanced PAD, providing versatile and durable solutions to challenging patterns of disease. Although there is little high-quality comparative effectiveness data to guide patient selection, existing evidence suggests that outcomes are dependent on definable patient factors such as distribution of disease, status of the limb, comorbid conditions, and conduit availability. As it stands, surgical revascularization remains the standard against which emerging percutaneous techniques are compared. This review summarizes the principles of surgical revascularization, patient selection, and expected outcomes, while highlighting areas in need of further research and technological advancement.
