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...

“…It is assumed that aneurysms for which an infection factor cannot be established develop either as a consequence of an autoaggressive process that results in the formation of inflammatory granulation tissue and leads to degenerative changes within the walls of the aorta; or that the inflammatory process associated with the atherosclerotic and degenerative changes within the walls of the aorta spreads to the surrounding tissues [8, 9, 11]. On the other hand, inflammatory aneurysms could develop as a result of infection and inflammation that encompass the thrombus in the aneurysmal sac; alternatively, such a process could cause destruction and rupture of the aortic walls, thus resulting in vessel dilatation [1, 3, 5]. As a result of this, infectious aneurysms are saccular in shape, with characteristic rapid growth and a strong tendency to rupture.…”

Osteolysis of vertebrae due to inflammatory aortic aneurysm is rarely observed. However, it is estimated that up to 10 % of infectious aneurysms coexist with bone tissue destruction, most commonly the vertebrae. Inflammatory aneurysms with no identified infection factor, along with infiltration of adjacent muscle and in particular extensive destruction of bone tissue have rarely been described in the literature. A case of inflammatory aneurysm with posterior wall rupture and inflammatory infiltration of the iliopsoas muscle and spine, together with extensive vertebral body destruction, is presented. The aneurysm was successfully treated with endovascular aneurysm repair EVAR.
