Abstract
Surgical site infection (SSI) is an important component of infections acquired from hospital. The most significant feature of vascular surgery different from other surgeries is frequent application of artificial grafts. Once SSI occurs after vascular operations with grafts, it might results in a serious disaster. Staphylococcus aureus and coagulase-negative Staphylococcus are the most common pathogenic bacteria for SSI after vascular surgery. Although SSI in vascular surgery often lacks of typical clinical characters, some clinical symptoms, laboratory data and certain imaging procedures may help to diagnose. In most cases of SSI after vascular procedures, the artificial grafts must be removed and sensitive antibiotics should be administered. However, for different cases, personalized management plan should be made depending on the severity and location of SSI.

Vascular surgery is a new interdisciplinary subject of medicine
CT and MRI, can be detected in vascular plants infected graft shift caused by the abscess or anastomotic aneurysm, selective joint use of such special vascular examination, diagnosis of vascular graft infection sensitivity can reach more than 80%, the specificity was 50% ~ 90%, and to help determine the surgical approach and the scope of 3; angiography in the planning of treatment has a guiding role; on suspicion of aortic graft infection patients must be two-way angiography, in order to understand the host and graft patency by the extent of infection and the proximal and distal vessels, in order to make further treatment
Aorta bilateral femoral artery graft infection treatment is difficult, because the inguinal region of vascular graft infection, affect the lower limb blood supply, for extra anatomic bypass reconstruction, the distal anastomosis should be built in the deep femoral artery or superficial femoral artery to artery, even, in order to avoid the occurrence of lower extremity ischemic necrosis
Summary
Vascular surgery is a new interdisciplinary subject of medicine. Besides has the general characteristics of other surgical disciplines, vascular surgery is characterized in that a variety of artificial graft (artificial blood vessels, stents, stent grafts) are widely used in clinical. Most vascular surgical operation is clean operation, but the chance of infection is usually increased, due to the application of artificial graft, and that vascular surgery patients are often elderly, and may be combined with a variety of internal medicine diseases such as diabetes, hypertension and heart disease, immune disease, weak body resistance. It’s not enough, sometimes, with antibiotic therapy alone for graft infection, and if necessary, removal of the infected vascular graft and revascularization pathway have to be operated [1,2,3], otherwise SSI can cause serious limb loss, organ failure, and even death
