“…1 It is reasonable to consider CT imaging as the initial imaging procedure in patients with suspected intraabdominal VGI. In the absence of recent manipulations, 1,[33][34][35] Several studies have reported that PET/CT is useful for the diagnosis of intra-abdominal VGI. 1,[28][29][30][31][32][42][43][44][45][46] Three recent studies summarized the role of PET/CT for the diagnosis of VGI.…”

The use of synthetic material for reconstructive vascular surgery was first reported during the early 1950s. Infection involving vascular graft prostheses is an infrequent but devastating complication of reconstructive vascular graft surgery and is associated with a high morbidity and, in some situations, mortality. Improvements in surgical techniques and graft design, including the use of native venous or arterial tissue, have reduced the frequency of infection and severity of complications from vascular graft infection (VGI). However, these advances have also led to more frequent vascular graft procedures occurring in a patient population with multiple underlying comorbidities that would have previously disqualified them as candidates for vascular reconstructive surgery. Underlying comorbidities, such as diabetes mellitus or immune compromise, increase the risk of infection and serious infection-related complications. The major complications of VGI include sepsis, amputation, disruption of infected anastomotic suture line with rupture or pseudoaneurysm formation, embolization of infected thrombi, reinfection of reconstructed vascular grafts, enteric fistulae to the small or large bowel, bacteremic spread of infection to other sites, and death. VGIs can be categorized broadly into those that occur in an extracavitary location, primarily in the groin or lower extremities, or in an intracavitary location, primarily within the abdomen or less commonly within the thorax. frequencyThe frequency of VGI depends on the anatomic location of the graft. The infection rate is 1.5% to 2% for most extracavitary grafts and as high as 6% with vascular grafts in the groin. [1][2][3][4][5][6][7][8][9] For intracavitary grafts, the infection rate is ≈1% to 5%. 1-6 Graft infection is most common after emergency procedures and after reoperation. [1][2][3][4]10 Aortic graft erosion or fistulous communication into the duodenum or other areas of the bowel reportedly occurs in 1% to 2% of patients after aortic reconstruction. 11,12 MicrobiologyThe microbiological cause of VGI has evolved over the years. 1 In early published studies, Staphylococcus aureus was the predominant microorganism recovered. 1,13 Improvements in surgical technique, administration of prophylactic antistaphylococcal antimicrobial therapy, and other factors have resulted in a changing microbiological epidemiology. Vascular graft surgery performed on patients with multiple underlying comorbidities and the increased frequency of emergency procedures have contributed to the changing spectrum of infection. Other factors such as changes in hospital flora, surgery in patients with complicated vascular anatomy, and multiple revisions of previous vascular surgery have resulted in a more diverse microbio- clInIcal stateMents anD GuIDelInes logical spectrum of infection, which includes multidrugresistant strains, polymicrobial infection, and Candida species. Gram-positive cocci accounts for at least two thirds of VGIs. 1,13 Infections caused by coagulase-negative staphylococ...

Early and accurate detection of prosthetic arterial graft infection is important because this serious complication of vascular surgery carries high morbidity and mortality rates. This report describes the use of a new method of isotopic imaging to detect graft infection using 99mTc-hexametazime-labelled leucocytes. Seventeen patients with potentially infected arterial grafts were imaged in addition to routine investigations but were managed according to our normal surgical practice. 99mTc-imaging was positive in eight patients with proven graft infection and falsely positive in one patient with a groin haematoma (89 per cent specificity). There were no false negatives (100 per cent sensitivity) after an average follow-up of 6 months (range 3-9 months). This technique has proved a reliable and rapid method of confirming graft infection.
