Abstract
OBJECTIVE This study aimed to describe surgical trends, survival, and infection related complications (IRC) in a Danish cohort of patients with infective native aortic aneurysms (INAAs). METHODS A retrospective nationwide cohort study including all patients in Denmark who were surgically treated for abdominal INAA between 2000 and 2020 was conducted. Patients were identified through the Danish vascular registry, Karbase, which is a database registering all patients treated with vascular surgery in Denmark. Subsequent data on clinical presentation, treatment, all cause mortality, and complications were obtained from the electronic patient charts. RESULTS Seventy-five patients were included in the study, of whom 60 (80%) were male, with a median age of 69 (IQR 64, 75) years. Open surgical repair (OSR) was performed in 54 (72%) patients and endovascular aortic repair (EVAR) in 21 (28%). Median follow up was 52 (IQR 32, 103) months. Open repair was consistently the most frequent treatment modality throughout the study period, but EVAR became more frequent over time. The 30 day survival of the total cohort was 97% (94 - 100%). Kaplan-Meier survival estimates for the cohort were 92% (95% CI 85 - 98%), 80% (95% CI 71 - 91%), 63% (95% CI 52 - 78%), and 48% (95% CI 35 - 66%) at one, three, five and 10 years, respectively. Patients treated by EVAR had comparable long term survival to patients treated by OSR, with a hazard ratio of 0.35 (95% CI 0.10 - 1.22), but was associated with better short term survival up to five years. The most common cause of death was sepsis. Five (9%) OSR patients had IRC compared with one (5%) EVAR patient. CONCLUSION In this nationwide study of patients treated for abdominal INAA, an increasing number of patients were surgically treated during the study period. Patients treated by EVAR demonstrated long term survival comparable to OSR. The incidence of post-operative IRC was low. These results should be interpreted with caution and prospective registries are needed.

Prognostic factors after open and endovascular repair for infected native aneurysms of the abdominal aorta and common iliac artery. J Vasc Surg 2024; 79:1379-1389. [PMID: 38280686 DOI: 10.1016/j.jvs.2024.01.199] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 01/13/2024] [Accepted: 01/21/2024] [Indexed: 01/29/2024]
Abstract
OBJECTIVE Infected native aneurysms (INAs) of the abdominal aorta and iliac arteries are uncommon, but potentially fatal. Endovascular aneurysm repair (EVAR) has recently been introduced as a durable treatment option, with outcomes comparable to those yielded by conventional open repair. However, owing to the rarity of the disease, the strengths and limitations of each treatment remain uncertain. The present study aimed to separately assess post-open repair and post-EVAR outcomes and to clarify factors affecting the short-term and late prognosis after each treatment. METHODS Using a nationwide clinical registry, we investigated 600 patients treated with open repair and 226 patients treated with EVAR for INAs of the abdominal aorta and/or common iliac artery. The relationships between preoperative or operative factors and postoperative outcomes, including 90-day and 3-year mortality and persistent or recurrent aneurysm-related infection, were examined. RESULTS Prosthetic grafts were used in >90% of patients treated with open repair, and in situ and extra-anatomic arterial reconstruction was performed in 539 and 57 patients, respectively. Preoperative anemia and imaging findings suggestive of aneurysm-enteric fistula were independently associated with poor outcomes in terms of both 3-year mortality (hazard ratio [HR], 1.62; 95% confidence interval [CI], 1.01-2.62; P = .046, and HR, 2.24; 95% CI, 1.12-4.46; P = .022, respectively) and persistent or recurrent infection (odds ratio [OR], 2.16; 95% CI, 1.04-4.49; P = .039, and OR, 4.96; 95% CI, 1.81-13.55; P = .002, respectively) after open repair, whereas omental wrapping or packing and antibiotic impregnation of the prosthetic graft for in situ reconstruction contributed to improved 3-year survival (HR, 0.60; 95% CI, 0.39-0.92; P = .019, and HR, 0.53; 95% CI, 0.32-0.88; P = .014, respectively). Among patients treated with EVAR, abscess formation adjacent to the aneurysm was significantly associated with the occurrence of persistent or recurrent infection (OR, 2.24; 95% CI, 1.06-4.72; P = .034), whereas an elevated preoperative white blood cell count was predictive of 3-year mortality (HR, 1.77; 95% CI, 1.00-3.13; P = .048). CONCLUSIONS Profiles of prognostic factors differed between open repair and EVAR in the treatment of INAs of the abdominal aorta and common iliac artery. Open repair may be more suitable than EVAR for patients with concurrent abscess formation.

[PMID: 38884073 PMCID: PMC11176620 DOI: 10.1016/j.ejvsvf.2024.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 02/16/2024] [Accepted: 05/08/2024] [Indexed: 06/18/2024] Open
Abstract
Objective Primary aorto-enteral fistula (PAEF) is a connection between the gastrointestinal tract and the aorta that occurs without previous aortic surgery. The aetiological factors include, but are not limited to, aneurysm, infection, and tumours. It is a life threatening condition if untreated and requires emergency vascular surgical repair. A secondary aorto-enteric fistula (AEF) can occur to a previously reconstructed aorta. This case report presents a unique case of a male patient who developed a primary AEF and subsequent secondary AEF with successful surgical outcomes, suggested to be due to tuberculous aortitis. Report The patient was diagnosed and treated for tuberculosis and developed a saccular aneurysm within six months. The PAEF was surgically corrected with a tube graft using a bovine pericardial patch, the defect in duodenum was sutured, and a retrocolic omental flap was created between the duodenum and aorta. He developed a small stable pseudoaneurysm during follow up, and then a secondary AEF two and a half years later, in which a connection between the pseudoaneurysm and duodenum was corrected using a new bovine aorto-aortic interposition graft using a bovine pericardium patch. The defect in the duodenum was also sutured in two layers and a new omental flap was created. Discussion The mortality rate of AEF is high and it is very unlikely that a patient will survive two AEFs without major complications. It is believed that there are extremely few double AEF cases described in the literature. The aetiological factor in the development of PAEF in this case was most likely the patient's aortic aneurysm, which was most likely of mycotic origin due to tuberculosis. The patient developed a pseudoaneurysm during follow up and it is uncertain whether the pulsatile pressure of the pseudoaneurysm led to the recurrence of the AEF.

Abstract
Penetrating aortic injuries represent critical medical emergencies that necessitate immediate intervention to prevent life-threatening consequences. When accompanied by the presence of an enormous right pleural false aneurysm, the clinical scenario becomes exceptionally rare and complex. This case report details the successful management of a patient who presented with a penetrating aortic ulcer and an extensive false aneurysm within the right pleura, employing an interdisciplinary approach involving cardiac surgeons, cardiologists, interventional cardiologists, and radiologists. The pivotal intervention involved the deployment of a covered and bare stent graft into the descending thoracic aorta to seal the aortic rupture. The patient's clinical condition stabilized postoperatively, with no signs of recurrent hemorrhage. This case underscores the importance of rapid diagnosis, timely intervention, and the collaborative efforts of a specialized medical team in successfully managing such complex vascular injuries. Early recognition and referral to specialized centers are essential for improving patient outcomes in cases of penetrating aortic injuries with associated giant pseudoaneurysms.

Abstract
OBJECTIVE The standard treatment of infected aortic aneurysms is open surgical repair but mortality rates remain high with the common cause of death being sepsis. Endovascular treatment of infected aortic aneurysms is another option and here we report the midterm outcomes of endovascular treatment for infected aortic aneurysms. METHODS Thirty-four patients with infected aortic aneurysms underwent endovascular and hybrid repair between December 2012 and June 2021. The patients were evaluated for early and midterm outcomes including postoperative mortality, morbidity, recurrent aortic infection, and midterm survival. RESULTS There were 34 patients who presented with infected aortic aneurysms with a mean age of 66.7 years (range, 26-89). Most of the patients presented with abdominal pain (94.1%) and fever (50.0%). The rate of positive blood culture for organisms was 32.4%. Salmonella was the most common organism. The procedures for treatment were endovascular repair using straight endograft, aorto-uni-iliac (AUI) endograft, bifurcated endograft, and thoracic endograft. Other procedures were endovascular repair with sandwich technique, chimney or periscope technique, and hybrid operation. The rate of in-hospital mortality and morbidity were 11.8% and 17.6%, respectively. Mean follow-up time was 21 months (range, 1-70). During the follow-up period, 7 (23.3%) patients had recurrent infection of aortic aneurysms and 5 patients required reoperation. Four patients died from septicemia and one patient died from cardiac disease. Male patients were more likely to have recurrent infection compared to females. The cumulative survival at 1 year and 2 years were 86.3% and 80.5%, respectively. CONCLUSION In this retrospective review of the endovascular treatment in the patients who presented with infected aortic aneurysms showed acceptable early and midterm outcomes.

Abstract
BACKGROUND To perform a systematic review on contemporary outcomes of endovascular repair and open surgical repair (OSR) for the treatment of mycotic aortic aneurysm (MAA). METHODS A comprehensive literature search on the management of MAAs with endovascular repair or OSR was performed between January 1998 and January 2023. Patient demographics, early and late outcomes were analyzed with respect to treatment modality and MAA location. RESULTS Forty-eight articles were included, encompassing a total of 1,358 patients (75.8% male; mean age 66.9 years; 1,372 aneurysms) treated by open (49.8%) or endovascular (50.2%) repair. Salmonella spp., and Staphylococcus spp. were the most prevalent pathogens in Asian and European countries respectively. An increasing number of descending thoracic MAAs were managed by endovascular repair (27.9% vs. 12.8%). Early mortality rates for supra- and infra-renal MAAs managed by endovascular repair were lower than OSR (suprarenal 5.4% vs. 43.2%; infrarenal 1.8% vs. 16.7%). Overall, endovascular repair demonstrated lower intraoperative (1.0% vs. 1.8%) and early mortality (6.5% vs. 15.9) rates than OSR. However, endovascular repair was associated with higher late sepsis rate (5.7% vs. 0.9%) and reintervention rate (17.6% vs. 7.3%). Pooled survival rates at 1- and 5-year were similar between the 2 groups. CONCLUSIONS Current literature suggest that endovascular repair is an effective and safe alternative to OSR for descending thoracic, suprarenal, and infrarenal MAAs. However, endovascular repair is associated with higher risk of infection-related complications and reintervention during follow-up.

Abstract
OBJECTIVE The European Society for Vascular Surgery (ESVS) has developed clinical practice guidelines for the care of patients with aneurysms of the abdominal aorta and iliac arteries in succession to the 2011 and 2019 versions, with the aim of assisting physicians and patients in selecting the best management strategy. METHODS The guideline is based on scientific evidence completed with expert opinion on the matter. By summarising and evaluating the best available evidence, recommendations for the evaluation and treatment of patients have been formulated. The recommendations are graded according to a modified European Society of Cardiology grading system, where the strength (class) of each recommendation is graded from I to III and the letters A to C mark the level of evidence. RESULTS A total of 160 recommendations have been issued on the following topics: Service standards, including surgical volume and training; Epidemiology, diagnosis, and screening; Management of patients with small abdominal aortic aneurysm (AAA), including surveillance, cardiovascular risk reduction, and indication for repair; Elective AAA repair, including operative risk assessment, open and endovascular repair, and early complications; Ruptured and symptomatic AAA, including peri-operative management, such as permissive hypotension and use of aortic occlusion balloon, open and endovascular repair, and early complications, such as abdominal compartment syndrome and colonic ischaemia; Long term outcome and follow up after AAA repair, including graft infection, endoleaks and follow up routines; Management of complex AAA, including open and endovascular repair; Management of iliac artery aneurysm, including indication for repair and open and endovascular repair; and Miscellaneous aortic problems, including mycotic, inflammatory, and saccular aortic aneurysm. In addition, Shared decision making is being addressed, with supporting information for patients, and Unresolved issues are discussed. CONCLUSION The ESVS Clinical Practice Guidelines provide the most comprehensive, up to date, and unbiased advice to clinicians and patients on the management of abdominal aorto-iliac artery aneurysms.

Abstract
BACKGROUND Infective native aortic aneurysms (INAAs), formerly called mycotic aneurysms, remain an uncommon disease with significant heterogeneity among cases; hence, there is lack of solid evidence to opt for the best treatment strategy. The present study aims to describe a 20-year experience at a single institution treating this uncommon condition. METHODS Retrospective study of all patients treated for INAA at a single academic hospital in Santiago, Chile, between 2002 and 2022. Clinical characteristics are described, as well as operative outcomes per type of treatment. Nonparametric Mann-Whitney U-test or Kruskal-Wallis tests were performed when appropriate, and results were reported as median and ranges. Survival at given timeframes was determined by a Kaplan-Meier curve, with analysis performed through a Cox regression model. RESULTS During the study period, 1,798 patients underwent aortic procedures at our center, of which 35 (1.9%) were treated for INAA. Of them, 25 (71.4%) were male. One patient had 2 INAAs. Median age was 69.5 years (range: 34-89 years). Of the 36 INAAs, the most frequent location was the abdominal and thoracic aorta in 20 (55.5%) and 11 (30.5%) cases, respectively, followed by the iliac arteries in 4 (11.1%) cases. One (2.7%) patient presented a thoracoabdominal INAA. Overall, endovascular treatment associated with long-term antibiotics was used in 20 (57.1%) patients: 4 of them underwent hybrid treatment. Fifteen (42.8%) patients underwent direct aortic debridement followed by in situ or extra anatomic revascularization. There was a significant difference in age between both treatment strategies (a median of 76.5 years for endovascular versus a median of 57 years for open, P = 0.011). The median hospital stay was 15 days (range: 2-70 days). The early complications rate (<30 postoperative days) was 20% (n = 7). Early mortality rate (inhospital or before postoperative 30 days) was 14.2% (n = 5). Median follow-up was 33 months (range: 6-216 months). The overall survival rates at 1, 3, and 5 years were 69.9% (standard error [SE] 8.0), 61.7% (SE 9.8), and 50.9% (SE 11.8), respectively. Five-year survival rate of patients undergoing endovascular treatment compared with open approach was 45.9% (SE 15.1) versus 80.0% (SE 17.8), respectively (P = 0.431). There were no significant differences in survival between open and endovascular treatment, hazard ratio 3.58 (confidence interval 95%: 0.185-1.968, SE ± 0.45 P = 0.454). CONCLUSIONS Patients treated by endovascular approach were older than patients treated by open approach. Even though, the open group had a higher 5-year survival rate than the endovascular group, not statically significance differences were found between treatments.

Abstract
Mycotic aneurysms are dilatations of an artery, a rare but severe complication arising from infectious obliteration of the vessel wall. Thoracic aneurysms often present with unspecific symptoms and multiple diagnostic and therapeutic challenges. In an advanced state, they have an increased risk of perforation and a high mortality rate. The surgical therapeutic approach has a high perioperative complication rate. In this study, we report a case of a thoracic mycotic aortic aneurysm in an immunocompromised pediatric patient caused by Klebsiella pneumoniae bacteremia. A combination of prompt antibacterial treatment and minimally invasive stent implantation showed a good outcome, avoiding possible severe surgical problems.

Abstract
OBJECTIVES Aortic infections are an uncommon but life-threatening disease. The material of choice for aortic reconstruction is still a matter of debate. The aim of this study is to examine the short and mid-term outcomes in the treatment of abdominal aortic infections using self-made bovine pericardium tube grafts. MATERIAL AND METHODS This retrospective, single-center study collected all patients who underwent in situ abdominal aortic reconstruction using self-made bovine pericardial tube grafts between February 2020 and December 2021 in a tertiary care center. Patient comorbidities, symptoms, radiological, bacteriological and peri-operative findings, as well as postoperative outcomes were analyzed. RESULTS Bovine pericardial aortic tube grafts were used in 11 patients (10 male, median age 68.7 years). Two patients presented a native aortic infection and nine had graft infections (four bypass grafts, four endografts and a plurioperated patient who had undergone both endovascular and open procedures). There were two emergent surgeries due to infectious aneurysm ruptures. All patients were symptomatic and the most frequent clinical finding was lumbar or abdominal pain (36%), followed by wound infection (27%) and fever (18%). Seven bifurcated and four straight pericardial tube grafts were needed. Purulent drainage was obtained around the previous graft or in the aneurysmal sac in 7 cases; intraoperative cultures were positive in 6 cases (Gram + bacteria). Two patients died in the immediate postoperative period (perioperative mortality 18%; urgent procedures 50%; scheduled procedures 11%). One patient had a major complication due to bilateral SARS-CoV2 pneumonia. There was one single reintervention to control hemostasis due to bleeding non-graft-related. The median follow-up was 14.1 months (3-24 months). CONCLUSIONS Our preliminary experience in the treatment of abdominal aortic infections by in situ reconstrucción with self-made bovine pericardial tube grafts shows promising results. These should be confirmed in the long term.

Abstract
The incidence of campylobacteriosis has substantially increased over the past decade, notably in France. Secondary localizations complicating invasive infections are poorly described. We aimed to describe vascular infection or endocarditis caused by Campylobacter spp. We included 57 patients from a nationwide 5-year retrospective study on Campylobacter spp. bacteremia conducted in France; 44 patients had vascular infections, 12 had endocarditis, and 1 had both conditions. Campylobacter fetus was the most frequently involved species (83%). Antibiotic treatment involved a β-lactam monotherapy (54%) or was combined with a fluoroquinolone or an aminoglycoside (44%). The mortality rate was 25%. Relapse occurred in 8% of cases and was associated with delayed initiation of an efficient antimicrobial therapy after the first symptoms, diabetes, and coexistence of an osteoarticular location. Cardiovascular Campylobacter spp. infections are associated with a high mortality rate. Systematically searching for those localizations in cases of C. fetus bacteremia may be warranted.

Abstract
OBJECTIVES This report aims to review the management and outcomes of Brucella-associated mycotic aortic aneurysms. METHODS This is a retrospective chart review at a tertiary-level healthcare system. IRB approval was waived per policy. RESULTS We describe a case of Brucella aortitis acquired from habitual contact with wild hogs. Clinical presentation included lower back pain and elevated white blood cell count. Diagnosis was confirmed with imaging showing an infrarenal abdominal aortic aneurysm and serology revealing elevated Brucella antibodies titers. The patient was initially managed with endovascular aortic repair and combined oral and intravenous antibiotics therapy. He then underwent explanation and extra-anatomical bypass due to symptomatic periaortic infection and interval development of type I endoleak. The patient was asymptomatic after his final operation at 24 months of follow-up and remained on suppressive oral antibiotic therapy. CONCLUSIONS An aortic aneurysm secondary to Brucella is a rare entity. A detailed history of long-term exposure to animals may be a clue to obtain serologic testing. Operative debridement and re-establishing of reliable blood flow combined with long-term antibiotic suppression are the mainstay of treatment.

Abstract
The Croatian Cardiovascular Tissue Bank (CTB) was established in June 2011. Activities managed by CTB are processing of heart valves and blood vessels, as well as quality control, storage, medical release and distribution of allografts. The aim of this report is to present CTB's vascular tissue activities and retrospectively evaluate the outcomes of their use in the University Hospital Centre Zagreb. Between June 2011 and July 2021, 90 vascular allografts (VAs) from 55 donors after brain death were referred to CTB. Only 54% of VAs met the tissue quality requirements while 46% of tissues were discarded. The most frequent reasons for discard were unacceptable morphology and initial microbiological contamination. Altogether 42 VAs were released for transplantation and 37 of them were used in 27 surgical procedures. The most common indication for surgery was prosthetic graft or stent infection. According to the anatomic position of vascular reconstruction, patients were divided in the aortic and peripheral reconstruction group. A total of 23 patients were treated. In the aortic reconstruction group 58% of patients did not experience any graft-related complications. In the group of patients who underwent peripheral reconstruction significant incidence of reinfection was observed highlighting it as a major graft-related complication. Despite the small patient groups and limited duration of follow-up, presented clinical outcomes provide valuable information on the efficacy of vascular allografts. Additional clinical results collected on a larger patient groups and comparison to other reconstructive treatment options are necessary.

Abstract
BackgroundInfected abdominal aortic and iliac artery aneurysms are considered acute and severe diseases with insidious onset, rapid development, and high mortality in vascular surgery. Currently, there is no better treatment, either anatomic or extra-anatomical repair.Case presentationFrom February 2018 to April 2022, 7 patients with infected abdominal aortic and iliac artery aneurysms did not have sufficient autologous venous material for repair. With the consent of the Ethics Committee of the hospital, it uses the autologous peritoneal fascial tissue with rectus sheath to repair or reconstruct the infected vessels in situ. There were 5 cases of infected abdominal aortic aneurysm, 1 case of an infected common iliac aneurysm, and 1 case of the infected internal iliac aneurysm. Aortoduodenal fistula was found in 3 cases, all of them were given duodenal fistula repair and gastrojejunostomy and cholecystostomy. Three cases of infected abdominal aortic aneurysms were repaired with the autologous peritoneal fascial tissue patch, and 2 cases of infected abdominal aortic aneurysms were reconstructed by the autologous peritoneal fascial tissue suture to bifurcate graft in situ, the autologous peritoneal fascial tissue suture reconstructed the rest 2 cases of infected iliac aneurysm to tubular graft in situ. It was essential that Careful debridement of all infected tissue and adequate postoperative irrigation and drainage. Antibiotics were administered perioperatively, and all patients were subsequently treated with long-term antibiotics based on bacterial culture and susceptibility results of infected tissues and blood. All 7 patients had underwent surgery successfully. But there were 2 cases died of anastomotic infection or massive hemorrhage after the operation, the other 5 cases survived. The follow-up time was 2–19 months. The enhanced CT of postoperation showed that the reconstructed arteries were smooth without obvious stenosis or expansion, and no abdominal wall hernia occurred.ConclusionIn situ repair or reconstruction with autologous peritoneal fascial tissue with rectus sheath is a feasible treatment for the infected aneurysm patients without adequate autologous venous substitute, but it still needs long-term follow-up and a large sample to be further confirmed.

Abstract
BackgroundWith the advancement of vascular anastomosis techniques in recent years, radical surgery for tumors combined with venous vascular resection and reconstruction has been widely used. This study intends to establish two different rat vein replacement models, and further analyze the pathological changes of blood vessels after replacement.MethodsBrown-Norway (BN) rats were selected as donors and recipients, randomly divided into control group, cuff group (1-week group, 2-week group, and 4-week group), and suture group (1-week group, 2-week group, and 4-week group), with 6 rats in each group. The perioperative conditions, inner diameter, flow velocity and histopathological changes of the replaced vessels at different time points were analyzed.ResultsBoth cuff group and suture group can safely establish the rat vein replacement model. From the surgical operation, the operation time and venous cross-clamp time in the cuff group were shorter than those in the suture group (P < 0.05). At 2 and 4 weeks after operation, the diameter of suture group was wider than that of cuff group, and the flow rate was faster (P < 0.05). With prolonged postoperative survival, the wall of the replaced vessels underwent infiltration of CD4+ and CD8+ lymphocytes and high TGF-β1 gene expression. This leads to the proliferation of blood vessels and intimal layer. The results of vascular pathological staining showed that the infiltration degree of CD4+ lymphocytes at 2 weeks after operation and CD8+ lymphocytes at 4 weeks after operation in the suture group was lighter than that in the cuff group (P < 0.05). Meanwhile, TGF-β1 gene content at 4 weeks after operation in suture group was significantly lower than that in cuff group (P < 0.05).ConclusionCompared with cuff method, suture method is more suitable for the study of long-term pathological changes after vein replacement in rats. The main pathological changes in the long term after venous replacement in syngeneic background may be vascular fibrosis caused by inflammatory cell infiltration.

Outcomes of patients with aortic vascular graft and endograft infections initially contra-indicated for complete graft explantation. J Vasc Surg 2022; 76:1364-1373.e3. [PMID: 35697306 DOI: 10.1016/j.jvs.2022.05.007] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 05/14/2022] [Accepted: 05/24/2022] [Indexed: 10/31/2022]
Abstract
OBJECTIVE Complete excision in patients with aortic vascular graft and endograft infections (VGEIs) is a significant undertaking, and many patients never undergo definitive treatment. Knowing their fate is important to be able to assess the risks of graft excision vs alternative strategies. This study analyzed their life expectancy and sepsis-free survival. METHODS VGEIs were diagnosed according to the Aortic Graft Infection (MAGIC) criteria, and patients turned down for graft removal from November 2006 to December 2020 were included. Primary endpoints were aortic-related and sepsis-free survival estimated using the Kaplan-Meier method. A Cox proportional hazards regression analysis was used to compute the hazard ratio (HR) and 95% confidence interval (CI) as estimates of survival without sepsis. RESULTS Seventy-four patients were included, with a median age of 71 years (range, 63-79 years). The index aortic repair was either open (n = 33; 44.6%), endovascular (n = 19; 25.7%), or hybrid (n = 22; 29.7%). Causative organisms were identified in 56 patients (75.7%). At presentation, 26 patients (35.1%) required salvage surgery, open (n = 22; 29.7%) or endovascular (n = 8; 10.8%), and 17 radiological drainage (23.0%). During follow-up, eight required drainage and 11 (14.9%) graft removal (five complete). Infectious complications included pseudoaneurysms (n = 14; 18.9%), rupture (n = 9; 12.2%), gastro-intestinal bleeding (n = 13; 17.6%), septic embolisms (n = 4; 5.4%), and thrombosis (n = 12; 16.2%). In-hospital mortality was 20.3% (n = 15), freedom from aortic-related death and overall survival was 77.1% (95% CI, 65.2%-85.3%) and 70.4% (95% CI, 58.3%-79.7%) at 1 year, and 61.7% (95% CI, 46.1%-74.0%) and 43.1% (95% CI, 29.2%-56.3%) at 5 years. Sepsis recurrence occurred in 37 patients (50.0%). Seven (16.3%) developed acquired antimicrobial resistance. Malnutrition (HR, 3.3; 95% CI, 1.4-7.6; P = .005), hemorrhagic shock at presentation (HR, 2.9; 95% CI, 1.0-8.2; P = .048), aorto-enteric fistulae (HR, 3.3; 95% CI, 1.3-8.4; P = .011), fungal coinfection (HR, 3.5; 95% CI, 1.2-11.5; P = .030), and infection with resistant micro-organisms (HR, 3.1; 95% CI, 1.1-8.3; P = .023) were significantly associated with worse survival without sepsis. CONCLUSIONS In-hospital and aortic-related mortality were significant, but with salvage surgery and antibiotic therapy, the median survival was 3 years. Sepsis recurrence remained frequent, and further procedures were needed. These outcomes should be considered when graft excision is proposed. Known predictors of adverse outcomes should become important points for discussion in multidisciplinary team meetings.

Abstract
Abstract
Background
Infectious aneurysms are rare in clinic with poor therapeutic outcomes. When artery rupture occurs, the disease tends to progress resulting in a high mortality, and there remains no ideal treatment.
Case presentation
We report a case of rupture of infectious iliac artery pseudoaneurysm, who was assigned to receive artery reconstruction with autologous fascial-peritoneal tissue and obtained satisfied short-term outcome. The follow-up of 6 months after operation was good and long-term follow-up is continuing.
Conclusion
The posterior rectus fascia-peritoneal layer seems to be a feasible autologous biomaterial for vascular substitution in urgent setting when no other autologous material was available.

Abstract
OBJECTIVE The existing literature on mycotic aortic aneurysm is scarce and focuses on treatment. This study evaluates the clinical characteristics, diagnostics, treatment and outcome of patients with a mycotic abdominal aortic aneurysm treated in a tertiary referral center. METHODS A retrospective cohort study was conducted including all patients with a proven mycotic abdominal aortic aneurysm admitted between May 2010 and July 2020. Primary outcome was mortality and secondary outcome included complications such as vascular graft/endograft infection. RESULTS Twenty-four patients with a mycotic abdominal aortic aneurysm were included. Patients had a mean age of 68 ± 9 years and 20 (83%) were male. Thirteen patients (57%) had positive preoperative blood cultures. Streptococcus pneumoniae was most frequently isolated by blood culturing, pus, and vascular or perivascular tissue cultures (17%). In 19 (83%) patients the mycotic abdominal aortic aneurysm was located infrarenally, in three (13%) patients suprarenally, and in one (4%) patient juxtarenally. Median follow-up was 20 (7-42) months. In eight patients (33%) vascular graft and or endograft infection was diagnosed after surgical repair. Ten (42%) patients died during the follow-up period. The main causes of death were vascular graft/endograft infection-related (n=4) and rupture of the mycotic abdominal aortic aneurysm (n=3). No patient characteristics could be identified as predictive for mortality. CONCLUSION This study shows a large variation in presentation, diagnostic approaches, and surgical and antibiotic treatment of mycotic abdominal aortic aneurysm. The detailed information about the diagnostic approaches to this rare disease and its antibiotic/other treatment contributes to existing knowledge of mycotic abdominal aortic aneurysm. Because of the individual variation patients should be discussed in a multidisciplinary team with a vascular surgeon, infectious disease specialist, and clinical microbiologist.

Abstract
Mycotic abdominal aortic aneurysms (MAAAs) are rare but life-threatening, and no standard therapy has yet been established. Effective surgery with intensive antimicrobial therapy is crucial; however, this can be fatal in immunocompromised patients. Only a few reports of MAAA with concomitant autoimmune disease exist; therefore, we were concerned about our lack of experience and knowledge about appropriate treatment. We report a 69-year-old male with an MAAA secondary to septic shock after spinal fusion surgery. He had also been on long-term oral immunosuppressants for systemic lupus erythematosus (SLE). After preoperative cephazolin, we performed debridement of infected tissue, graft replacement with a rifampicin-bonded prosthesis, and omentopexy. On the 52nd post-operative day, he was transferred back to the previous attending hospital under oral antibiotics and prednisolone. MAAA in patients with SLE should be treated with in situ replacement using an antimicrobial prosthetic or biological graft with thorough debridement and omentopexy, followed by antimicrobials and immunosuppressants, as needed.

Abstract
PURPOSE OF REVIEW Infective native aortic aneurysms (INAAs) are challenging and complex with both bacteraemia and an aneurysm prone to rupture. They are fatal unless recognized and treated promptly. The rarity of the disease makes it unfamiliar to most physicians, which might delay both diagnosis and treatment.The present review aims to outline the recently published diagnostic algorithm of INAAs, the main characteristics of the disease and present an overview of contemporary treatment strategies. RECENT FINDINGS New terminology, definition, diagnostic algorithm and reporting standards have recently been proposed for INAAs. Current evidence concerning the treatment of INAAs is founded on retrospective register-based multicentre studies and small single-centre studies. Recent findings encourage the use of endovascular aortic repair (EVAR) for surgical treatment of INAAs. Although EVAR, as a surgical approach, does not drain the infection, the postoperative infection-related complication rates (IRCs) are similar to the ones reported after open surgical repair (OSR) with aortic prosthetic reconstruction and extensive debridement. IRCs carry over 50% risk of being fatal. Postoperative mortality after EVAR remains considerably lower supporting the use of method for aged and comorbid group of patients. Biological grafts have the benefit of being more resistant to reinfection. OSR with biological reconstruction is a promising surgical approach for patients fit for open surgery; however, data are scarce and long-term follow-up is lacking. SUMMARY The treatment of INAAs should be guided by experienced multidisciplinary team and tailored individually based on patients' condition and centres' experience. An international consensus document is warranted to enable further research on this disease.

Abstract
OBJECTIVE The aim of our systematic review and meta-analysis was to demonstrate the clinical outcomes of open surgical repair (OSR) and endovascular aneurysm repair (EVAR) for infective native aortic aneurysms (INAAs). METHODS MEDLINE, Embase, and Cochrane Databases were searched for articles reporting OSR and/or EVAR repair of INAA. The methodological quality of included studies was assessed by the Newcastle-Ottawa scale and Moga-Score. Random-effects models were used to calculate the pooled measures. RESULTS A total of 34 studies were included, with 22 studies reporting OSR alone, 6 studies reporting EVAR alone and 6 comparative studies for INAAs. The pooled estimates of infection-related complications (IRCs) were 8.2% (95% CI 4.9%-12.2%) in OSR cohort and 23.2% (95% CI 16.1%-31.0%) in EVAR cohort. EVAR was associated with a significantly increased risk of IRCs compared with OSR during follow-up (OR 1.9, 95% CI 1.0-3.7). As for survival outcomes, the summary estimate rate of all cause 30-day, 3-month and 1-year mortality in OSR cohort were 11.7% (95% CI 7.7%-16.1%), 21.6% (95%CI 16.3%-27.4%) and 28.3% (95% CI 20.5%-36.7%; I2=50.47%), respectively. For EVAR cohort, the summary estimate rate of all cause 30-day, 3-month and 1-year mortality were 4.9% (95% CI 1.1%-10.4%), 9.4% (95% CI 2.7%-18.7%) and 22.2% (95% CI 12.4%-33.7%), respectively. EVAR was associated with a significantly decreased of 30-day mortality (OR 0.2, 95% CI 0.1-0.6). However, no difference was found between EVAR and OSR in 3-month (OR 0.2, 95% CI 0-1.1), 1-year all-cause mortality (OR 0.4, 95% CI 0.1-1.1) or aneurysm-related mortality (OR 1.4, 95% CI 0.5-3.9). Moreover, no difference of incidence of reintervention was observed (OR 2.6, 95% CI 0.9-7.7; I2=53.7%) between two groups. CONCLUSIONS EVAR could provide better short-term survival than OSR in patients with INAAs. However, patients undergoing EVAR suffered from higher risks of IRCs. EVAR could be considered as an alternative for low-risk patients with well-controlled infections or patients considered high-risk for open reconstruction.

Abstract
OBJECTIVE The purpose of the present study was to evaluate the survival and freedom from reinfection for patients with infected native aortic aneurysms (INAAs) treated with in situ revascularization (ISR), using either open surgical repair (OSR) or endovascular aneurysm repair (EVAR), and to identify the predictors of outcome. METHODS Patients with INAAs who had undergone ISR from January 2005 to December 2020 were included in the present retrospective single-center study. The diagnosis of INAAs required a combination of two or more of the following criteria: (1) clinical presentation, (2) laboratory results, (3) imaging findings, and (4) intraoperative findings. The primary endpoint was 30-day mortality. The secondary endpoints were in-hospital mortality, estimated survival, patency, and freedom from reinfection using the Kaplan-Meier method. The predictive factors for adverse outcomes were evaluated using the Mann-Whitney U test or the Fisher exact test and multivariate regression analysis. RESULTS A total of 65 patients (53 men [81.5%]; median age, 69.0 years; interquartile range, 61.5-75.0 years) were included, 31 (47.7%) were immunocompromised, 60 were symptomatic (92.3%), and 32 (49.2%) had presented with rupture, including 3 aortocaval fistulas (4.6%) and 12 aortoenteric fistulas (18.5%). The most common location was infrarenal (n = 39; 60.0%). Of the 65 patients, 55 (84.6%) had undergone primary OSR with ISR, 3 (4.6%) had required EVAR as a bridge to OSR, and 8 (12.3%) had undergone EVAR as definitive treatment. The approach was a midline laparotomy for 44 patients (67.7%), mostly followed by reconstruction and aortic-aortic bypass (n = 28; 40.6%) and the use of a silver and triclosan Dacron graft (n = 30; 43.5%). Causative organisms were identified in 55 patients (84.6%). The 30-day and in-hospital mortality rates were 6.2% (n = 4) and 10.8% (n = 7). The median follow-up was 33.5 months (interquartile range, 13.6-62.3 months). The estimated 1- and 5-year survival rates were 79.7% (95% confidence interval [CI], 67.6%-87.7%) and 67.4% (95% CI, 51.2%-79.3%). The corresponding freedom from reinfection rates were 92.5% (95% CI, 81.1%-97.1%) and 79.4% (95% CI, 59.1%-90.3%). On multivariate analysis, in-hospital mortality increased with uncontrolled sepsis (P < .0001), rapidly expanding aneurysms (P = .008), and fusiform aneurysms (P = .03). The incidence of reinfection increased with longer operating times (P = .009). CONCLUSIONS The selective use of ISR and OSR combined with targeted antimicrobial therapy functioned reasonably well in the treatment of INAAs, although larger, prospective, multicenter studies with appropriately powered comparative cohorts are necessary to confirm our findings and to determine the best vascular substitute and precise role of EVAR as a bridge to OSR or definitive treatment.

Abstract
In the present case report, we have described concomitant, rapidly expanding, abdominal and thoracic mycotic aortic pseudoaneurysms in a patient who had originally presented for right arm superficial thrombophlebitis and a right-hand abscess in the presence of methicillin sensitive Staphylococcus aureus bacteremia. Within 12 days, the patient had developed a rapidly expanding paravisceral mycotic abdominal aortic pseudoaneurysm that required open surgical repair. After the initial operation, she developed a thoracic mycotic aortic aneurysm that ultimately required open surgical repair. Her postoperative course after the initial operation was complicated by decompensated hepatitis C cirrhosis that required convalescence before repair of the thoracic aneurysm. Follow-up data were available for ≤10 months after the initial operation.

Abstract
Background The surgical treatment of aortic infections (AIs) is challenging. In situ aortic reconstructions represent nowadays the favored therapy for fit patients and xenogeneic materials are used increasingly. The aim of this study was to present our experience with xenogeneic reconstructions for AI using self-made bovine pericardium tubes and/or the biosynthetic Omniflow® II graft. Methods This retrospective single-center study included all patients undergoing xenogeneic aortic and aortoiliac reconstructions from December 2015 to June 2020. Patient comorbidities, symptoms, procedural characteristics, types of pathogens and postoperative outcomes were analyzed. Results Twenty-eight patients [23 male (82%), median age 68 (range, 28–84) years] were included. Ten patients (36%) had native AIs and 18 (64%) had graft infections, including 3 (11%) aortoesophageal and 2 (7%) aortoduodenal fistulas (ADF). Twenty-four patients (86%) were symptomatic, the most common symptoms being contained aortic rupture (n=8) and sepsis (n=4). The surgical procedures were infra- and juxtarenal aortic repairs (n=11, 39% and n=7, 25%), thoracoabdominal aortic repairs (type IV: n=1, 4%; type V: n=3, 11%), descending thoracic aortic repairs (n=4, 14%) and 2 reconstructions (7%) involving the ascending aorta/aortic arch. Most were urgent (n=10, 43%) or emergent operations (n=11, 35%). Identification of pathogen(s), mostly Gram-positive bacteria, was possible in 25 patients (89%). Twelve patients (43%) had polymicrobial infections and 6 (21%) infections with multi-resistant bacteria. In-hospital mortality was 32% (n=9) due to acute cardiac failure (1/9), endocarditis (1/9), bleeding (3/9) and sepsis (4/9). The most frequent complications were transient need for dialysis (n=12, 43%) and persisting sepsis (n=11, 39%). Two early occlusions of Omniflow® II grafts were observed (7%). Median follow-up (FU), during which 2 patients died of non-aortic causes, was 14 months (95% CI: 9–19 months). Freedom from reoperation was 100%, there was no evidence for reinfection during FU. Conclusions Xenogeneic orthotopic reconstructions for AI can be performed at all aortic levels. Combining bovine pericardium and the Omniflow® II graft can be useful for reconstructing the branched aortic segments and both materials show appropriate early to midterm outcomes. Nonetheless, AIs are serious conditions associated with relevant morbidity/mortality rates, even in a specialized center.

Nationwide study of surgery for primary infected abdominal aortic and common iliac artery aneurysms. Br J Surg 2021; 108:286-295.

Abstract
BACKGROUND Primary infected aneurysms of the abdominal aorta and iliac arteries are potentially life-threatening. However, because of the rarity of the disease, its pathogenesis and optimal treatment strategy remain poorly defined. METHODS A nationwide retrospective cohort study investigated patients who underwent surgical treatment for a primary infected abdominal aortic and/or common iliac artery (CIA) aneurysm between 2011 and 2017 using a Japanese clinical registry. The study evaluated the relationships between preoperative factors and postoperative outcomes including 90-day and 3-year mortality, and persistent or recurrent aneurysm-related infection. Propensity score matching was used to compare survival between patients who underwent in situ prosthetic grafting and those who had endovascular aneurysm repair (EVAR). RESULTS Some 862 patients were included in the analysis. Preceding infection was identified in 30.2 per cent of the patients. The median duration of postoperative follow-up was 639 days. Cumulative overall survival rates at 30 days, 90 days, 1 year, 3 years and 5 years were 94.0, 89.7, 82.6, 74.9 and 68.5 per cent respectively. Age, preoperative shock and hypoalbuminaemia were independently associated with short-term and late mortality. Compared with open repair, EVAR was more closely associated with persistent or recurrent aneurysm-related infection (odds ratio 2.76, 95 per cent c.i. 1.67 to 4.58; P < 0.001). Propensity score-matched analyses demonstrated no significant differences between EVAR and in situ graft replacement in terms of 3-year all-cause and aorta-related mortality rates (P = 0.093 and P =0.472 respectively). CONCLUSION In patients undergoing surgical intervention for primary infected abdominal aortic and CIA aneursyms, postoperative survival rates were encouraging. Eradication of infection following EVAR appeared less likely than with open repair, but survival rates were similar in matched patients between EVAR and in situ graft replacement.

Abstract
We report a case of mycotic thoracic aortic aneurysm managed by staged hybrid repair. A 30-year-old male patient with polysubstance abuse presented with chest pain and elevated white blood cell count. CTA performed showed a rapidly developing mycotic thoracic aortic pseudoaneurysm. He underwent emergent thoracic endovascular aortic repair followed 24 hours later by surgical debridement of the posterior mediastinum. Cultures grew Methicillin-resistant Staphylococcus aureus and patient was placed on long term antibiotics. The patient was asymptomatic on follow up one year after his final operation with complete exclusion of pseudoaneurysm with no endoleak.

Abstract
OBJECTIVE Different graft materials have been proposed for in situ reconstruction in the setting of vascular graft infection (VGI). We analyzed the long-term outcomes after in situ aortoiliac reconstruction with cryopreserved allografts. METHODS We performed a retrospective analysis of patients who had undergone in situ aortoiliac reconstruction with cryopreserved arterial allografts for VGI from 2000 to 2015. The end points were the perioperative and long-term mortality and graft-related complications, including stenosis, occlusion, pseudoaneurysm, and reinfection. RESULTS A total of 33 patients (91% male) with a median age of 67 years (range, 53-83 years) had undergone in situ aortoiliac reconstruction with cryopreserved allografts. The 30-day mortality was 6% (n = 2); both deaths were related to the allograft (one early allograft-enteric fistula and one graft rupture). Another two patients had experienced early (≤30 days) graft-related events (one allograft-enteric fistula and one graft limb occlusion), for an early graft-related complication rate of 12% (n = 4). Of the 31 discharged patients, 13 (42%) had died after a median of 47 months (range, 2-97 months). The median follow-up for the 18 remaining patients was 96 months (range, 10-146 months). The estimated survival at 1, 3, and 5 years was 88%, 81%, and 66%, respectively. Nine patients (29%) had experienced at least one of the following graft-related events during follow-up, including graft stenosis requiring intervention in five (16%), graft occlusion in four (13%), pseudoaneurysm in three (10%), and reinfection in two patients (6%). The estimated freedom from any first graft-related event at 1, 3, and 5 years was 78%, 71%, and 62%, respectively. The estimated primary patency and primary assisted patency at 1 and 3 years was 87% and 79%, and 90% and 83%, respectively. CONCLUSIONS In situ aortoiliac reconstruction with cryopreserved allografts to treat VGI was associated with relevant perioperative graft-related complications. Although the reinfection rate was acceptable, other graft-related complications were frequent in the long term, in particular, graft occlusion and stenosis.

Abstract
BACKGROUND The aim of this study is to identify preoperative and intraoperative factors associated with in-hospital mortality of intact abdominal aortoiliac aneurysm repair. METHODS In this observational study, prospectively collected information included demographics, risk factors, comorbidities, aneurysm characteristics (including special aneurysm presentation, i.e., inflammatory, mycotic/infected, aortocaval fistula), investigations, and operative variables. Receiver operating characteristic) curve analysis of the Glasgow aneurysm score (GAS) and the Vascular Study Group of New England (VSGNE) score was performed in the subgroup of bland aneurysms undergoing isolated elective repair. RESULTS A total of 928 cases with intact aortoiliac aneurysms had an elective (n = 882) or urgent (n = 46) repair, associated with an in-hospital mortality of 1.7% and 8.7%, respectively (P = 0.01). Open repair (n = 514) was a predictor of higher mortality (3.3% vs. 0.5% for endovascular aneurysm repair [EVAR], n = 414, odds ratio [OR] 7.1, P = 0.003), and so was the pre-EVAR era (4.8% vs. 1.3% in the EVAR era, OR 4.0, P = 0.004). Other significant predictors included the presence of abdominal/back pain (7.5% vs. 1.3%, OR = 6.0, P = 0.001), preoperative angiography (7% vs. 1.6%, OR = 4.5, P = 0.01), special aneurysm presentation (10.9% vs. 1.5%, OR = 8.1, P < 0.001), concomitant major procedures (19% vs. 1.7%, OR = 14.0, P < 0.001), serious intraoperative complications (9.1% vs. 1.5%, OR = 6.6, P = 0.001), median number of transfused units of blood intraoperatively (2 and 0 for cases with and without mortality, respectively, P < 0.001), and procedure duration (270 and 150 min for cases with and without mortality, respectively, P < 0.001). Open repair (OR = 4.5, P = 0.05), special aneurysm presentation (OR = 6.58, P = 0.001), and concomitant major procedures (OR = 14.3, P < 0.001) were independent predictors of higher mortality. ROC curve analysis for the GAS (P = 0.87) and VSGNE score (P = 0.10) failed to demonstrate statistical significance in the subgroup of bland aneurysms undergoing isolated elective repair. CONCLUSIONS Our study has demonstrated independent risk factors for mortality, which should be considered when contemplating aortoiliac aneurysm repair. We failed to externally validate the GAS and VSGNE score.

Abstract
Abdominal aortic aneurysm (AAA) is a relatively common and potentially fatal disease. The management of AAA has undergone extensive changes in the last two decades. High quality vascular surgical registries were established early and have been found to be instrumental in the evaluation and monitoring of these changes, most notably the wide implementation of minimally invasive endovascular surgical technology. Trends over the years showed the increased use of endovascular aneurysm repair (EVAR) over open repair, the decreasing perioperative adverse outcomes and the early survival advantage of EVAR. Also, data from the early EVAR years changed the views on endoleak management and showed the importance of tracking the implementation of new techniques. Registry data complemented the randomized trials performed in aortic surgery by showing the high rate of laparotomy-related reinterventions after open repair. Also, they are an essential tool for the understanding of outcomes in a broad patient population, evaluating the generalizability of findings from randomized trials and analysing changes over time. By using large-scale data over longer periods of time, the importance of centralization of care to high-volume centres was shown, particularly for open repair. Additionally, large-scale databases can offer an opportunity to assess practice and outcomes in patient subgroups (e.g. treatment of AAA in women and the elderly) as well as in rare aortic pathologies. In this review article, we point out the most important paradigm shifts in AAA management based on vascular registry data.

Abstract
BACKGROUND The treatment of aortic infections is complex, and the material of reconstruction remains discussed. Several alternatives were suggested in the literature. The current consensus is the use of biological material. The aim of this study was to evaluate the short-term results of bovine pericardium xenografts. METHODS Between November 2016 and June 2019, we included consecutively all the patients presenting with native aortic infections in which arterial reconstruction was carried out with tubular bovine pericardium grafts sutured longitudinally. We collected the preoperative, peroperative, and postoperative clinical, radiological, biological, and bacteriological characteristics. The recurrence of infection, the graft failures, and the morbimortality were analyzed. RESULTS Twelve patients including three women were treated. Their mean age was 68.4 ± 9 years. They presented 2 thoracic, 4 thoracoabdominal, 4 abdominal, and 2 aortoiliac aneurysms. The diagnosis was made using angio-CT in all the cases and was confirmed by positron emission tomography (PET) scan in 7 cases and blood cultures in 9 cases. Peroperative cultures were positive in 11 cases. Antibiotics were given in 9 patients before operation for a median duration of 9 (3-19) days and in all the patients postoperatively for a median duration of 42 (1-540) days. The median follow-up was 355 (98-839) days. Six medical complications occurred, including 2 (16.6%) leading to death in the immediate postoperative period. No reoperation was needed. The PET scan returned positive in 1/10 cases (10%) during the follow-up. The diameter of the grafts was preserved, without any defect observed on the angio-CT. CONCLUSIONS Short-term results showed a mechanical resistance to infection of the bovine pericardium. This biological material offers a promising alternative with multiple advantages including availability, simplicity of preparation, and adaptability to the various locations of the aortic infection.

Comparing Venous Reconstructions and Antimicrobial Graft Reconstructions in Mycotic Abdominal Aortic Aneurysms and Aortic Graft Infections. Ann Vasc Surg 2019; 61:270-277.

Abstract
BACKGROUND The perioperative mortality and morbidity rates of surgical repair of mycotic abdominal aortic aneurysms and aortic graft infections are high, and the appropriate treatment is debated. This retrospective study compared venous and antimicrobial prosthetic aortic graft reconstructions. METHODS All patients of the Northwest Clinics and St. Antonius Hospital who were treated for mycotic abdominal aortic aneurysms or aortic graft infections between January 1, 2008, and January 1, 2018, were analyzed. Exclusion criterion was treatment other than venous or antimicrobial reconstructions. Primary end points were 30-day complications and mortality rates and 3-year overall survival. Secondary end points were reintervention-free survival, persistent infection and reinfection rates, and hospital length of stay. RESULTS Fifty-one patients met the inclusion criteria, of whom 32 underwent venous reconstructions and 19 antimicrobial prosthetic aortic graft reconstructions. Baseline characteristics did not differ significantly between these groups, except for duration of surgical repair, which was longer in the venous group. The 30-day and 1-year mortality rates, reinfection rates, complication rates, and hospital length of stay did not significantly differ between the groups. The 3-year overall survival was 77% for venous reconstruction compared with 66% for antimicrobial reconstruction (P = 0.781). The 30-day reintervention rate was 19% for the venous group compared with 42% for the prosthetic group (P = 0.071). Reintervention-free survival at 3 years was 46% for the venous group compared with 52% for the prosthetic group (P = 0.615). CONCLUSIONS Venous reconstruction tends to have better 3-year overall survival and lower 30-day reintervention rates compared with antimicrobial prosthetic graft reconstruction in patients with mycotic abdominal aortic aneurysms or abdominal aortic graft infections. In the acute setting, antimicrobial prosthetic graft reconstruction is a valuable solution due to the shorter operation time and similar 30-day mortality and complication rates.
