Abstract
OBJECTIVE To report the early and mid-term outcome of complex endovascular repair (EVAR) for paravisceral infective native aortic aneurysms (INAA). METHODS Interrogation of a prospectively maintained database identified consecutive patients who underwent non-elective complex EVAR for paravisceral INAAs in a single institution between December 2013 and June 2020. All patients were considered to have definite INAAs based on diagnostic criteria. Patients who had prior aortic repair were excluded. RESULTS A total of 26 patients (19 men; mean age 67 years [SD = 11.4]; median diameter 60 mm [IQR: 55-73]) with acute symptomatic (n = 24) or contained ruptured (n = 2) aneurysms underwent surgeon-modified fenestrated EVAR (SM-FEVAR; n = 24) or chimney-periscope EVAR (CHIMPS; n = 2). Median observed follow-up was 36.2 months (18.3-53.5). Nine patients had positive venous blood cultures and a further seven had recent or concomitant infection. All patients received pre- and post-operative antibiotic therapy and rifampicin-soaked endografts. A total of 95 vessels were targeted for preservation and 86 were stent-grafted. One vessel occluded intra-operatively and a further 3 occluded within 30 days. The 30-day/in-hospital mortality was 11.5% (n = 3), and the estimated 1- and 3-year survival (±SD) was 85% ± 7%. Infection-related complications (IRCs) occurred in two patients: both developed new INAA within 30 days of index repair and were treated by EVAR with no mortality. Estimated 3-year freedom from late re-intervention was 100%. One patient required infrarenal EVAR for a non-infective aneurysm at 43 months. CONCLUSION Complex EVAR for paravisceral INAAs is associated with acceptable early and mid-term outcomes and is an acceptable alternative to open surgery. We propose that these patients are managed with long-term antimicrobials, impregnation of graft material with rifampicin, and rigorous post-operative surveillance. CLINICAL IMPACT A multi-disciplinary approach is required to deliver the best possible outcome for patients with this challenging aortic pathology.

Ann Vasc Surg 2024; 99:193-200. [PMID: 37805170 DOI: 10.1016/j.avsg.2023.07.109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 07/22/2023] [Accepted: 07/24/2023] [Indexed: 10/09/2023]
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
Campylobacter fetus (C. fetus) demonstrates a preference for vascular tissue and is an infrequent etiology of mycotic aortic arteritis (MAA), mostly occurring in the abdominal aorta. MAA characteristically has a rapid progression to aneurysm formation and subsequently, to aortic rupture. We present a 73-year-old woman with non-aneurysmal mycotic thoracic aortic arteritis (MTAA) complicated with a rupture caused by C. fetus. She presented after four days of pain in the lower abdomen. Contrast-enhanced computed tomography revealed non-aneurysmal descending thoracic aorta arteritis and an abdominal aorta aneurysm, and the blood cultures were positive for C. fetus. Antibiotic therapy relieved the abdominal pain. However, eight days after the antibiotic therapy, she died because of a rupture of the non-aneurysmal MTAA. The non-aneurysmal MTAA caused by C. fetus ruptured while the infection was being treated with appropriate antibiotics, and there was no sign of arterial dilatation. An early open or endovascular repair after a short pre-operative antibiotic therapy may be required for non-aneurysmal MAA caused by C. fetus. More cases of non-aneurysmal MAA caused by C. fetus are needed to determine the clinical course and to decide the treatment strategy.

Abstract
Mycotic thoracic aortic aneurysm (MTAA) is an aneurysm of the aorta caused by infection of the vessel tissue through microbial inoculation of the diseased aortic endothelium. It is most commonly caused by bacteria. Rarely, it can be caused by fungi. However, viral aortic aneurysm has never been reported. Depending on the area and time period investigated, the infections organism discovered may vary significantly. Little is known about the natural history of MTAA due to its rarity. It is not known if they follow the same pattern as other TAAs. However, it is unclear whether MTAA follows a similar clinical course. The combination of clinical presentation, laboratory results, and radiographic results are used to make the diagnosis of MTAA. Treatment of MTAA is complex since patients frequently present at a late stage, frequently with fulminant sepsis, as well as concomitant complications such as aneurysm rupture. While medical treatment, including antibiotics, is recommended, surgery is still the mainstay of management. Surgery to treat MTAA is complicated and carries a high risk of morbidity and mortality and includes both open repairs and endovascular ones. In this review, we explore the etiology, pathogenesis, clinical presentations, diagnostic modalities as well as treatment management available for MTAA.

Abstract
Background Isolated mycotic internal iliac artery aneurysms are rare and management of these patients can be complex. Case summary We present a rare case of isolated mycotic right internal iliac artery aneurysm caused by Salmonella enteritides. This was managed in stages – with intravenous antibiotics, followed by endovascular stenting and embolization, and subsequent percutaneous drainage of the remnant collection. The patient had no perioperative complications, and has remained well at more than 18 months post-operatively with no evidence of stent infection. Conclusion A minimally-invasive approach combining endovascular aneurysm repair and percutaneous drainage is a viable option in the management of a mycotic internal iliac artery aneurysm.

Recurrent infection is more common after endovascular versus open repair of infected abdominal aortic aneurysm: Systematic review and meta-analysis. J Vasc Surg 2021; 75:348-355.e10. [PMID: 34500028 DOI: 10.1016/j.jvs.2021.07.240] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 07/29/2021] [Indexed: 01/16/2023]
Abstract
OBJECTIVE Controversy has continued regarding the use of endovascular aneurysm repair (EVAR) vs open aneurysm repair (OAR) for infected abdominal aortic aneurysms (AAAs). In the present study, we investigated the comparative outcomes of EVAR and OAR for the treatment of infected AAAs. METHODS We conducted a systematic review and meta-analysis using the MEDLINE and EMBASE databases through May 2021. We included studies that had described both EVAR and OAR for the treatment of infected AAAs. The primary endpoints were the rates of recurrent infection and related rupture and/or death. Perioperative and 1-year mortality and readmissions and reinterventions were also analyzed. RESULTS Fourteen observational studies describing a total of 1203 patients (EVAR, 359 [29.8%]; OAR, 844 [70.2%]) were eligible for qualitative analysis. The baseline characteristics included diabetes mellitus (33.2%), fever at presentation (71.6%), rupture at diagnosis (26.1%), and positive blood cultures (52.5%). The mean follow-up period ranged from 12 to 40 months. The use of EVAR became more prevalent in recent years (2016-2020, 32.4%) compared with the former period (2010-2015, 13.8%; P < .0001). Fenestrated, branched, or concomitant visceral debranching EVAR was performed in 6.1% of cases. In OAR, surgical debridement was consistently performed, and in situ reconstruction was applied in 82.2% and an omental flap in 51.5%. In nine studies considered for quantitative analysis, the patients' background (EVAR, n = 264; OAR, n = 274) were statistically balanced. The crude rates of recurrent infection and related rupture or death were 13.6% (95% confidence interval [CI], 8.8%-18.5%) and 4.9% (95% CI 1.8%-8.0%), respectively. The pooled analyses depicted significantly higher rates of recurrent infection after EVAR than after OAR (relative risk [RR], 2.42; 95% CI, 1.80-3.27; P < .0001; I2 = 0%). Recurrent infection-related rupture or death (RR, 1.51; 95% CI, 0.70-3.23; P = .29; I2 = 0%), perioperative death (RR, 0.80; 95% CI, 0.39-1.65; P = .55; I2 = 35%), 1-year mortality (hazard ratio, 1.12; 95% CI, 0.97-1.28; P =.13; I2 = 0%), and readmission or reintervention (RR, 1.16; 95% CI, 0.74-1.82; P =.52; I2 = 0%) were not significantly different statistically between the two groups. Funnel plots showed no evidence of publication bias. Sensitivity analyses of leave-one-out meta-analysis confirmed higher rates of recurrent infection after EVAR. CONCLUSIONS EVAR has become more prevalent as the initial treatment of infected AAAs. Although operative and 1-year survival were similar between OAR and EVAR groups, recurrent infection was more frequent after EVAR. This limitation should be weighed in selecting patients for EVAR in infected AAAs. Postoperative graft and infection surveillance are critical, especially after EVAR.

Abstract
We report a case of aortoenteric fistula 2 years following endovascular aortic aneurysm repair (EVAR) for mycotic aneurysm presenting as upper gastrointestinal bleeding. Initial CT angiogram did not reveal the bleeding or connection to bowel, but endoscopy was suspicious of endograft in the duodenum. Management required a multidisciplinary approach. To stabilise the patient and to control bleeding, a 'bridging' endograft extension was performed. This was followed by open surgical removal of the EVAR endograft and lower limb in situ revascularisation. During postoperative recovery, the patient developed atypical, staged multisystemic symptoms (cardiac, pulmonary and neurological). With increasing awareness of the COVID-19 pandemic, the patient was found SARS-CoV-2-positive, which explained the progression of his symptoms. This was also reflected on other case reports in literature later.

Abstract
BACKGROUND Mycotic abdominal aorta aneurysm (MAAA) is a rare and life-threatening condition. Because of its rarity, there is a lack of adequately powered studies and consensus on its treatment and follow up. This study aimed to review the outcomes following surgical intervention for MAAA in a single tertiary centre and to formulate a management protocol based on available evidence and expert opinion. MATERIALS AND METHODS Data were collected by retrospective review of case records of all patients who underwent repair of MAAA in a single tertiary referral centre from 2001 to 2018. Demographic, clinical and outcome data were analysed and compared with previously published series in the literature. A management protocol was formulated based on available literature which was then reviewed and modified as per expert opinion from multidisciplinary discussions. RESULTS Seventeen patients underwent repair of MAAA during the study period including 4 Open repairs, 4 surgeon modified fenestrated endovascular aortic aneurysm repairs (SM FEVAR) and 9 endovascular aortic aneurysm repairs (EVAR). One-year overall survival was 94.1%, 3-year survival was 81.8% and 5-year survival was 75.0%. The infection-free survival at 1, 3, and 5 years was 87.5%, 81.8% and 62.5%, respectively. The overall survival and infection-free survival curves for Open repair, EVAR and SM FEVAR when compared using Log Rank (Mantel-Cox) test and did not show any statistically significant difference. CONCLUSIONS Management of MAAA with selective use of open or endovascular repair, in combination with appropriate long-term antibiotic therapy, can achieve acceptable outcomes. The proposed protocol can aid as a guiding document for the management of MAAA but needs taking into consideration individual patient variability and local expertise.

Abstract
Focal infections caused by nontyphoidal Salmonella (NTS) are relatively rare and usually self-limited. Those with cardiac surgical history are predisposed to intrathoracic seeding, including mediastinal infections and abscesses. We report a case of a 39-year-old Hispanic male with a complex past medical history of Tetralogy of Fallot with an initial presentation of Salmonella gastroenteritis and concern for sepsis. The patient did not clinically improve on ceftriaxone despite appropriate cultures and susceptibilities, and another source of infection was speculated. A chest CT scan showed development of a mediastinal abscess with compression of the right ventricular outflow tract. The patient was not deemed an appropriate surgical candidate and was managed conservatively on ceftriaxone and ciprofloxacin. He was discharged in stable condition. This case of NTS infection associated with a mediastinal abscess is a rare occurrence, and management is complicated. To improve morbidity and mortality, early imaging is essential to diagnose distal seeding of the infection in patients with enteral infections who do not show clinical improvement despite appropriate antibiotic treatment. Surgery is the standard of care, but conservative management might be required in certain high-risk cases.

Recommendations on Securing Microbiological Specimens to Guide the Multidisciplinary Management of Infective Native Aortic Aneurysms. Ann Vasc Surg 2020; 68:536-541. [PMID: 32502673 DOI: 10.1016/j.avsg.2020.05.059] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 05/23/2020] [Accepted: 05/23/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND The absence of recommendations for the systematic collection of microbiological specimens to help determine the management of infective native aortic aneurysms (INAAs) may lead to diagnostic difficulty and suboptimal antibiotic treatment. In this review, we attempt to establish recommendations in the field by identifying current strategies for the diagnosis and management of INAA and comparing them with those for infective endocarditis (IE). METHODS A systematic literature review of Medline and ScienceDirect databases was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses)methodology to identify guidelines for the management of INAA. These guidelines were scrutinized for recommendations concerning the procurement of microbiological specimens according to a defined protocol and involvement of specialists in infectious diseases and compared with current practice for IE. RESULTS Three guidelines were found to have sections dedicated to INAA. Of these, none provided any recommendations concerning the procurement of microbiological specimens for diagnostic and therapeutic purposes. The guidelines from the American Heart Association recommend that patients with INAA should be managed by a team of specialists (including representation from the fields of infectious diseases and/or microbiology). Current guidelines for the investigation and management of IE provide detailed recommendations concerning the procurement of microbiological specimens for diagnostic and therapeutic purposes, as well as the involvement of specialists in infectious medicine in multidisciplinary management. CONCLUSION This article emphasizes the absence of recommendations for the optimal diagnosis and management of patients with INAAs. While specific research is required to create evidence-based recommendations, application of strategies to identify microorganisms and multidisciplinary team management derived from the management of IE may be both safe and appropriate for the clinical management of this highly complex and heterogeneous group.

Abstract
BACKGROUND Primary mycotic aneurysm of the aorta (MAA) is a rare and potentially life-threatening disease. Endovascular aneurysm repair (EVAR) of MAAs involving the paravisceral aorta has been rarely reported. The purpose of this study is to report our experience with chimney EVAR (CHEVAR) in patients with MAAs involving the paravisceral aorta. METHODS We performed a retrospective review of all patients treated with EVAR at our institution during the years 2009-2019. Of those, we identified the patients who were treated with CHEVAR for MAAs. Diagnosis of MAAs was based on clinical presentation, abnormal laboratory results, and a computed tomography scan suggestive of a MAA. The data collected included patient demographics, clinical presentation, the antibiotic regimen before and after the surgery, preoperative imaging, surgical details, and perioperative and long-term morbidity and mortality. RESULTS During the study period, we performed 54 cases of CHEVARs for aortic aneurysms. Of those, 8 (15%) were performed for mycotic aneurysms involving the visceral segment. Six (75%) were men, and the mean age was 68 years (range: 59-76). All patients were symptomatic at the time of diagnosis, presenting with either back or abdominal pain. A total of 16 visceral vessels (celiac trunk, 2; superior mesenteric artery, 7; right renal artery, 4; and left renal artery, 3) were revascularized with parallel grafts (PGs). Six patients required 2 PGs, 1 patient required 3 PGs, and 1 patient had a single PG inserted. Fifteen (94%) PGs were upward-pointing chimney stent grafts, and 1 was placed in a downward-pointing "periscope" configuration. Eight visceral arteries in 6 patients were sacrificed, either by preoperative occlusion or intentional coverage with the endograft during the procedure. The vessels sacrificed included 4 celiac trunks and 4 renal arteries (3 main branches and 1 accessory renal artery). Technical success was achieved in all patients. One patient expired in the perioperative period. One patient developed an infection-related complication. One patient experienced worsening of his renal function and eventually required dialysis. Of the 4 patients who underwent intentional sacrifice of a kidney, all experienced a moderate decrease in renal function from the baseline ( mean preoperative and postoperative serum creatinine 0.76 mg/dL and 1.2 mg/dL, respectively, increase of 43%). The mean follow-up was 8 months (range: 3-28 months). During this period, 2 patients expired, 1 from an aneurysm-related cause. No stent occlusion of the PGs occurred and no reintervention due to endoleaks was required. No patient required explanation of the stent grafts or conversion to an open repair. CONCLUSIONS CHEVAR is a feasible and safe treatment modality for MAAs involving the visceral segment. Occasionally, intentional occlusion of the selected visceral arteries may be required to minimize the risk of gutter endoleaks in this urgent setting. Further follow-up is needed to accurately assess the durability of this repair.

J Vasc Surg 2020; 72:531-540. [PMID: 32061482 DOI: 10.1016/j.jvs.2019.09.060] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2019] [Accepted: 09/29/2019] [Indexed: 10/25/2022]
Abstract
OBJECTIVE Mycotic aneurysms of the abdominal aorta (MAAA) can be treated by open repair (OR) or endovascular aneurysm repair (EVAR). This nationwide study provides an overview of the situation of MAAA treatment in The Netherlands in 2016. METHODS A retrospective cohort study was conducted with all centers that registered aortic abdominal aneurysms in the Dutch Surgical Aneurysm Audit in 2016. Questionnaires on 1-year outcomes were sent to all centers that treated patients with MAAA. The primary aim was to determine 30-day and 1-year mortality and morbidity of OR- and EVAR-treated patients. Morbidity was determined by the need for reoperations and the number of readmissions to the hospital. RESULTS Twenty-six MAAA were detected in the Dutch Surgical Aneurysm Audit database of 2016, resulting in an incidence of 0.7% of all registered abdominal aortic aneurysms. The 30-day mortality for OR and EVAR treated patients was 1 in 13 and 0 in 13, respectively. Major and minor reinterventions within 30 days were needed for two (one OR and one EVAR) and two (one OR and one EVAR) patients, respectively. Two patients (15.4%) in the OR group and one patient (7.7%) in the EVAR group were readmitted to hospital within 30 days. In total, 1-year outcomes of 23 patients were available. In the OR group, one patient (9.1%) died in the first postoperative year. There was one major reintervention (removal of endoprosthesis and spiralvein reconstruction) in the EVAR group. Two patients (18.2%) treated with OR and two (16.7%) treated with EVAR required a minor reintervention. In both groups, four patients (OR, 36.4%; EVAR, 33.3%) were readmitted to hospital within 1 year postoperatively. CONCLUSIONS Both OR- and EVAR-treated patients show acceptable clinical outcomes after 30 days and at the 1-year follow-up. Depending on the clinical course of the patient, EVAR may be considered in the management of this disease.

Abstract
OBJECTIVE Mycotic aortic aneurysms and aortic graft infections (aortic infections [AIs]) are rare but highly morbid conditions. Open surgical repair is the "gold standard" treatment, but endovascular repair (EVR) is increasingly being used in the management of AI because of the lower operative morbidity. Multiple organisms are associated with AI, and bacteriology may be an important indication of mortality. We describe the bacteriology and associated outcomes of a group of patients treated with an EVR-first approach for AI. METHODS All patients who underwent EVR for native aortic or aortic graft infections between 2005 and 2016 were retrospectively reviewed. Primary end points were 30-day mortality and overall mortality. The primary exposure variable was bacteria species. Logistic regression analysis was used to determine association with mortality. Kaplan-Meier survival analysis was used to estimate survival. RESULTS A total of 2038 EVRs were performed in 1989 unique and consecutive patients. Of those, 27 patients had undergone EVR for AI. Thirteen presented ruptured (48%). Eighteen (67%) were hemodynamically unstable. Ten had a gastrointestinal bleed (37%), whereas others presented with abdominal pain (33%), fever (22%), chest or back pain (18.5%), and hemothorax (3.7%). Twenty patients had a positive blood culture (74%), with the most common organism being methicillin-resistant Staphylococcus aureus (MRSA) isolated in 37% (10). Other organisms were Escherichia coli (3), Staphylococcus epidermidis (2), Streptococcus (2), Enterococcus faecalis (1), vancomycin-resistant Enterococcus (1), and Klebsiella (1). Thirteen patients had 4 to 6 weeks of postoperative antibiotic therapy, six of whom died after therapy. Fourteen were prescribed lifelong therapy; 10 died while receiving antibiotics. On univariate analysis for mortality, smoking history (P = .061) and aerodigestive bleeding on presentation (P = .109) approached significance, whereas MRSA infection (P = .001) was strongly associated with increased mortality. On multivariate analysis, MRSA remained a strong, independent predictor of mortality (adjusted odds ratio, 93.2; 95% confidence interval, 1.9-4643; P = .023). Overall 30-day mortality was 11%, all MRSA positive. At mean follow-up of 17.4 ± 28 months, overall mortality was 59%. Overall survival at 1 year, 3 years, and 5 years was 49%, 31%, and 23%. Kaplan-Meier survival analysis demonstrated that MRSA-positive patients had a significantly lower survival compared with other pathogens (1-year, 20% vs 71%; 5-year, 0% vs 44%; P = .0009). CONCLUSIONS In our series of AI, the most commonly isolated organism was MRSA. MRSA is highly virulent and is associated with increased mortality compared with all other organisms, regardless of treatment. Given our results, EVR for MRSA-positive AI was not a durable treatment option.

Abstract
Objective This study evaluates the overall survival and the infection-relapse after endovascular repair (Endo) vs. open surgery (Open) for mycotic aortic aneurysms and the potential influence of perioperative severity of infection to the decision-making on the long-term survival. Design A multicenter, retrospective analysis of 5247 consecutive aortic aneurysm repair performed from January 2003 to December 2017 at five tertiary medical centers was conducted. Among the study population, 257 patients with mycotic aortic aneurysms s were identified. Methods: Finally, 73 patients were enrolled in the cohort after exclusion and a 1:1 propensity-matched analysis. The study cohort drawn from matched data included 37 patients in the Endo group and 36 patients in the Open group. The primary endpoint was overall survival. Secondary endpoints included infection-relapse during the follow-up. Univariate and multivariate Cox regression analyses were used to assess predictors for late mortality. Results The mean follow-up time for the entire cohort was 41 months (range, 1 to 135 months). Among propensity-matched patients, there was no significant difference in baseline characteristics. There was no difference in overall survival ( P = 0.083) between the groups at five years, but Open group was associated with a lower infection-relapse incidence during the follow-up ( P = 0.011). Subgroup analysis revealed a better survival rate for Open in patients with severe infection ( P = 0.003) or small periaortic abscess ( P = 0.049). Conclusion There were no significant differences between Endo and Open in overall survival. However, Open was a more definite option with less infection-relapse and had potential advantages for patients with severe infection or with a small periaortic abscess.

Abstract
A 56-year-old man presenting with massive melena and loss of consciousness was diagnosed with an infected thoracoabdominal aneurysm, an aortoduodenal fistula, and Leriche syndrome following an evaluation by computed tomography. Emergency surgery for uncontrolled infection included the reconstruction of the superior mesenteric and bilateral renal arteries using a four-branched graft. The aortoduodenal fistula was resected after omental filling, and an enterostomy was performed for feeding. Intestinal reconstruction was performed in two stages. The patient was discharged on postoperative day 48 and was without evidence of recurrence at 23 months postoperatively.

Abstract
OBJECTIVE Endovascular techniques have been increasingly used to treat mycotic aortic aneurysms. However, apart from survival, the potential benefits of open surgery and endovascular repair for mycotic aortic aneurysms are poorly understood. The aim of this study was to evaluate the short- and mid-term outcomes after open surgery versus endovascular repair for mycotic aortic aneurysms. METHODS All patients treated for mycotic aortic aneurysms at Peking University People's Hospital between 2001 and 2017 were identified. Survival was analyzed using Kaplan-Meier analysis and log-rank tests. The reoperation rate was analyzed using a competing-risk analysis. RESULTS Forty-three patients were identified. The mean follow-up time was 41 months (median, 29; range, 1-135 months). The 30-day mortality in the open surgery group was 8.7% (2/23) versus 5% (1/20) in the endovascular repair group (P = .999). The overall survival for open surgery and endovascular repair was 78% versus 75%, respectively, at 1 year, and 69% versus 41% (P = .210), respectively, at 5 years. But during the follow-up, the open surgery group demonstrated multiple benefits, including a shorter length of hospital stay (26.80 ± 14.1 days vs 42.73 ± 21.22 days, P = .026), fewer readmissions (mean 0.61 vs 1.30, P = .037), and lower infection-related reoperations (P = .018) than endovascular repair at 3 years. Subgroup analysis revealed better survival for open surgery in patients with a periaortic mass less than 20 mm (P = .03). CONCLUSIONS There were no significant differences between endovascular repair and open surgery in survival. However, in the mid-term, the potential benefits of open surgery are favorable compared with endovascular repair, including lower infection-related reoperation rates and reduced medical burden.

Abstract
Background Nontyphoidal Salmonella (NTS) is a pathogen that causes several human clinical illnesses, most commonly gastroenteritis. Focal infections are rare and are generally reported in the gastrointestinal and genitourinary systems. Very few studies have reported NTS abscess as a postoperative complication. Case report We describe an elderly patient who developed NTS bacteremia and mediastinal abscess after aortic valve replacement. Conclusions This report describes an extremely rare occurrence of an NTS mediastinal abscess complicating a surgical procedure. The patient may have acquired the pathogen from a snake kept as a family pet and likely developed bacteremia followed by seeding of the surgically damaged tissues.

Abstract
Objective This study was performed to assess the efficacy and outcome of endovascular aneurysm repair (EVAR) for treatment of primary mycotic aortic aneurysms (PMAAs). Methods Fourteen consecutive patients who presented with PMAA from April 2010 to July 2017 were retrospectively reviewed. Preoperative, intraoperative, and postoperative clinical data were recorded, and late infection-related complications and long-term survival were assessed. Results The aneurysms were located in the abdominal aorta in 10 patients and in the left common iliac artery in 4 patients. Positive microbial cultures were found in 12 patients, including Salmonella species in 11 and Streptococcus in 1. The remaining two patients had negative culture results. Ten patients received preoperative antibiotics before elective EVAR for 7 ± 9 days after admission. Four patients who underwent emergent EVAR due to ruptured aneurysms were given their first dose of antibiotics before EVAR. Three patients underwent surgical drainage, and six underwent percutaneous drainage within 30 days after EVAR. No death occurred within 30 days of the initial procedure. The mean follow-up was 34.8 (range, 3-84 months). One patient underwent re-intervention to resolve obstruction of the iliac/femoral artery 5 months postoperatively. Relapse of infection occurred in six patients (42.8%) during follow-up; infection-related death occurred in three of these patients. The other patients recovered with either conversion to open radical surgery or medical therapy. The actuarial 7-year survival after EVAR was 75.7%. Conclusions EVAR and aggressive antibiotic therapy might be suitable for PMAAs. Favorable results may be typical for infection caused by Salmonella.

Abstract
Objective: There is striking paucity in consensus on the terminology, definition, and diagnostic criteria of mycotic aortic aneurysms. This literature study aims to elucidate this scientific omission, discuss its consequences, and present a proposition for reporting items on this disease. Methods: A systematic literature review on PubMed and Medline using mycotic and infected aortic aneurysms between 1850 and 2017 was performed. Articles were assessed according to a protocol regarding terminology, definition, and diagnostic criteria. Case series with less than 5 patients were excluded. Results: A total of 49 articles were included. The most prevalent term was mycotic aortic aneurysm but there was no widely accepted definition. Most modern publications used a diagnostic workup based on a combination on clinical presentation, laboratory results, imaging findings, and intraoperative findings. How these protean variables should be balanced was unclear. A proposition of reporting items was framed and consisted of definition of disease used, basis of diagnostic workup, exclusion criteria, patient characteristics, laboratory and imaging findings, aneurysm anatomy, details on treatment, pre/postoperative antibiotic treatment, and details on follow-up. Conclusions: This article emphasizes the need to standardize definition, terminology, and diagnostic criteria for mycotic aortic aneurysms and proposes reporting items enhancing comparability between studies.

Abstract
PURPOSE Infected aneurysm of the aorta and adjacent arteries is rarely occurring and can be fatal without surgical intervention. Within the medical community, the most efficacious treatment strategy to address infected aortic aneurysm remains controversial. In this study, we have reviewed our treatment experience with 109 patients. METHODS We included in our study all consecutive patients treated for primary infected aortic aneurysm at our facility between 1995 and 2011. Aneurysm-related mortality was defined as the presence of in-hospital and late mortality related to infection or postoperative complications. RESULTS The median patient age was 72 years (range, 35-88), and 87 (80%) were male. Pathogen was isolated in 101 patients, and the most common microorganism identified was non-typhoid Salmonella in 61 (60%), followed by Staphylococcus aureus in 16 (16%) and Streptococci species in 7 (7%). Eighty-five (78%) patients underwent surgical treatment. Surgery included open repair with in-situ graft replacement in 77 (71%) and endovascular repair in 8 (7%). The aneurysm-related mortality rate was 67% in medically treated and 21% in surgically treated patients, with a median follow-up duration of 31.5 months (range 1-189). Additionally, risk factors for aneurysm-related mortality included old age, chronic lung disease, psoas muscle abscess, short duration of preoperative antibiotics, no operation, and probably endovascular repair. CONCLUSIONS Non-typhoid Salmonella was the most common pathogen found in our study group patients with infected aortic aneurysm. It appears that prolonged preoperative antibiotic treatment followed by open in-situ graft replacement remains the preferred and most effective treatment strategy.

Abstract
Ruptured mycotic aneurysms occur infrequently in current clinical practice, and a pneumococcal etiology is even more rare. This case report describes a patient who initially presented with catheter lab activation for an acute ST-elevation myocardial infarction, receiving a full Plavix load. She was subsequently found to have a ruptured aortic aneurysm and underwent emergency surgical repair, with intraoperative findings of an aorta seeded with Streptococcus pneumonia. A retrospective evaluation of her history revealed clues of a previous upper respiratory infection and long-standing back pain. The subsequent literature review summarizes presentations and outcomes in previously reported, ruptured pneumococcal aneurysms and describes the relatively common occurrence of aortic conditions masquerading as acute myocardial infarctions. We provide recommendations to help approach similar situations in the future.

Abstract
INTRODUCTION An abdominal aortic aneurysm (AAA) infection is rare and can be difficult to manage, with high morbidity and mortality. We present a patient who suffered an infected AAA after undergoing a laparoscopic cholecystectomy and discuss the surgical management options. PRESENTATION OF CASE A 69-year-old male presents with a rapidly enlarging AAA 4 weeks following laparoscopic cholecystectomy. He was managed with open debridement, washout and repair of the aneurysm, but suffered ongoing sequelae of Escherichia coli sepsis. DISCUSSION The options for surgical management of infected AAA include open, endovascular and combined approaches. Recent papers report successful use of endovascular repair of infected AAAs but this is an ongoing area of research. CONCLUSION Infection of an AAA is associated with high mortality and long-term morbidity and requires optimal treatment. Surgical options include open debridement and repair, endovascular aneurysm repair (EVAR) or a combined approach.

Abstract
Primary mycotic aneurysms of the aorta are a rare but life-threatening condition. A 59-year-old woman developed a back abscess secondary to an insect bite. A computed tomography scan revealed 3 concomitant mycotic aneurysms, including a rupture. Staged repair was undertaken: immediate open repair for contained rupture of a type IV thoracoabdominal aortic aneurysm, followed by endovascular repair of a descending thoracic aneurysm 3 weeks later and finally an aortic arch hybrid repair of a left subclavian artery aneurysm 16 months later. She remains well postoperatively. There is currently no consensus on the timing of repair or modality of treatment of mycotic aneurysms. Each patient should be treated individually based on aneurysm location, rupture, and comorbidities, as shown by this case.

Abstract
Mycotic aneurysms, especially outside the aorta, are uncommon, with group A Streptococcus a particularly rare cause. We report a case of extra-aortic mycotic aneurysm following a sore throat without demonstrable bacteremia where identification of the pathological organism was made by molecular diagnostic techniques after a standard laboratory culture was negative.
