Hu X, Yan L. A secondary abdominal aorta-duodenal fistula accompanied with acquired Immune Deficiency Syndrome presented with recurrent sepsis: a case report. BMC Infect Dis 2024; 24:669. [PMID: 38965458 PMCID: PMC11223345 DOI: 10.1186/s12879-024-09559-8] [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: 06/29/2023] [Accepted: 06/24/2024] [Indexed: 07/06/2024] Open
Abstract
BACKGROUND Abdominal aorta-duodenal fistulas are rare abnormal communications between the abdominal aorta and duodenum. Secondary abdominal aorta-duodenal fistulas often result from endovascular surgery for aneurysms and can present as severe late complications. CASE PRESENTATION A 50-year-old male patient underwent endovascular reconstruction for an infrarenal abdominal aortic pseudoaneurysm. Prior to the operation, he was diagnosed with Acquired Immune Deficiency Syndrome and Syphilis. Two years later, he was readmitted with lower extremity pain and fever. Blood cultures grew Enterococcus faecium, Salmonella, and Streptococcus anginosus. Sepsis was successfully treated with comprehensive anti-infective therapy. He was readmitted 6 months later, with blood cultures growing Enterococcus faecium and Escherichia coli. Although computed tomography did not show contrast agent leakage, we suspected an abdominal aorta-duodenal fistula. Esophagogastroduodenoscopy confirmed this suspicion. The patient underwent in situ abdominal aortic repair and received long-term antibiotic therapy. He remained symptom-free during a year and a half of follow-up. CONCLUSIONS This case suggests that recurrent infections with non-typhoidal Salmonella and gut bacteria may be an initial clue to secondary abdominal aorta-duodenal fistula.

Abstract
A male patient, 70 years of age, was evaluated for an infected thoracic endovascular aneurysm repair (TEVAR). After presenting with persistent fever, a positron emission tomography scan found an infected aortic stent graft. The patient underwent open repair with explantation of the infected TEVAR, extensive periaortic debridement, graft replacement with a Dacron graft, and complete coverage with a latissimus dorsi muscle flap. Tissue culture revealed Clostridium spp. He was discharged home with long-term ampicillin and sulbactam. A postoperative computed tomography scan showed no recurrence of infection. Open surgery with latissimus muscle flap coverage is an achievable option for infected TEVAR.

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.

Kim H, Choi HZ, Kwon Y, Labropoulos N. Clinical outcome of graft removal versus preservation in abdominal aortic graft infection: a systematic review and meta-analysis. Ann Surg Treat Res 2023; 105:207-218. [PMID: 37908379 PMCID: PMC10613822 DOI: 10.4174/astr.2023.105.4.207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 07/27/2023] [Accepted: 08/17/2023] [Indexed: 11/02/2023] Open
Abstract
Purpose The purpose of this study was to compare the clinical outcomes of abdominal aortic graft infection (AGI) treated with removal of the graft vs. graft preservation. Methods The electronic databases PubMed, Embase, and Cochrane Library for studies that reported on AGI were searched. Observational studies and case series of at least 10 cases that reporting on the prevalence, microbiology, and outcomes of AGI were included. Results Our search identified 23 studies that met our inclusion criteria, reporting on a total of 873 patients who underwent open surgical repair (OSR) or endovascular aneurysm repair (EVAR). Of these patients, 833 received graft removal, and 40 received graft preservation. The prevalence of AGI was reported to be 1.0% (95% confidence interval [CI], 0.5%-1.8%) after OSR and 0.4% (95% CI, 0%-1.1%) after EVAR. The pooled estimates of 1-year, 2-year, and 5-year mortality were 28.7% (95% CI, 19.4%-38.8%), 36.6% (95% CI, 24.6%-49.5%), and 51.8% (95% CI, 38.4%-65.1%) in the graft removal group and 16.1% (95% CI, 4.1%-32.2%), 18.5% (95% CI, 5.7%-35.1%), and 50.0% (95% CI, 31.6%-68.4%) in the graft preservation group. The 30-day mortality rate's risk ratio (RR) for graft removal vs. preservation was 0.98 (95% CI, 0.40-2.38), while the 1-year mortality rate's RR was 3.44 (95% CI, 1.60-7.42). Conclusion The 30-day mortality rate of AGI treatment was found to be high, whether using graft removal or preservation. In selected patients, implementing antibiotics with graft preservation as an initial management may be helpful in reducing the mortality rate.

Appearance of aseptic vascular grafts after endovascular aortic repair on [(18)F]fluorodeoxyglucose positron emission tomography/computed tomography. World J Radiol 2023; 15:241-249. [PMID: 37662425 PMCID: PMC10473915 DOI: 10.4329/wjr.v15.i8.241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 06/15/2023] [Accepted: 07/27/2023] [Indexed: 08/24/2023] Open
Abstract
BACKGROUND Diagnosis of prosthetic vascular graft infection with [(18)F]fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) allows for early detection of functional changes associated with infection, based on increased glucose utilization by activated macrophages and granulocytes. Aseptic vascular grafts, like all foreign bodies, can stimulate an inflammatory response, which can present as increased activity on 18F-FDG PET/CT. Consequently, distinguishing aseptic inflammation from graft infection, though important, can be difficult. In the case of endovascular aneurysm repair (EVAR), a minimally invasive procedure involving the transfemoral insertion of an endoprosthetic stent graft, the normal postoperative appearance of these grafts on 18F-FDG PET/CT can vary over time, potentially confounding study interpretation. AIM To investigate the visual, semiquantitative, and temporal characteristics of aseptic vascular grafts in patients status post EVAR. METHODS In this observational retrospective cohort study, patients with history of EVAR who underwent 18F-FDG PET/CT for indications other than infection were identified retrospectively. All patients were asymptomatic for graft infection - no abdominal pain, fever of unknown origin, sepsis, or leukocytosis - at the time of imaging and for ≥ 2 mo after each PET/CT. Imaging studies such as CT for each patient were also reviewed, and any patients with suspected or confirmed vascular graft infection were excluded. One hundred two scans performed on 43 patients (34 males; 9 females; age = 77 ± 8 years at the time of the final PET/CT) were retrospectively reviewed. All 43 patients had an abdominal aortic (AA) vascular graft, 40 patients had a right iliac (RI) limb graft, and 41 patients had a left iliac (LI) limb graft. Twenty-two patients had 1 PET/CT and 21 patients had from 2 to 9 PET/CTs. Grafts were imaged between 2 mo to 168 mo (about 14 years) post placement. Eight grafts were imaged within 6 mo of placement, including three that were imaged within three months of placement. The mean interval between graft placement and PET/CT for all 102 scans was 51 ± 39 mo. PET/CT data was reconstructed with region-of-interest analysis of proximal, mid and distal portions of the grafts and background ascending aorta. Maximum standardized uptake value (SUVmax) was recorded for each region. SUVmax-to-background uptake ratios (URs) were calculated. Visual assessment was performed using a 2-pattern grading scale: Diffuse (homogeneous uptake less than liver uptake) and focal (one or more areas of focal uptake in any part of the graft). Statistical analysis was performed. RESULTS In total, there were 306 AA grafts, 285 LI grafts, 282 RI grafts, and 306 ascending aorta background SUVmax measurements. For all 102 scans, mean SUVmax values for AA grafts were 2.8-3.0 along proximal, mid, and distal segments. Mean SUVmax values for LI grafts and RI grafts were 2.7-2.8. Mean SUVmax values for background were 2.5 ± 0.5. Mean URs were 1.1-1.2. Visual analysis of the scans reflected results of quantitative analysis. On visual inspection, 98% revealed diffuse, homogeneous 18F-FDG uptake less than liver. Graft URs and visual pattern categories were significantly associated for AA graft URs (F-ratio = 21.5, P < 0.001), LI graft URs (F-ratio = 20.4, P < 0.001), and RI graft URs (F-ratio = 30.4, P < 0.001). Thus, visual patterns of 18F-FDG uptake corresponded statistically significantly to semiquantitative URs. The age of grafts showing focal patterns was greater than grafts showing diffuse patterns, 87 ± 89 vs 50 ± 37 mo, respectively (P = 0.02). URs were significantly associated with graft age for AA grafts (r = 0.19, P = 0.001). URs were also significantly associated with graft age for LI grafts (r = 0.25, P < 0.0001), and RI grafts (r = 0.31, P < 0.001). Quartiles of similar numbers of graft (n = 25-27) grouped by graft age indicated that URs were significantly higher for 4th quartile vs 2nd quartile URs (F-ratio = 19.5, P < 0.001). When evaluating URs, graft SUVmax values within 10%-20% of the ascending aorta SUVmax is evident in aseptic grafts, except for grafts in the oldest quartiles. In this study, grafts in the oldest quartiles (> 7 years post EVAR) showed SUVmax up to 30% higher than the ascending aorta SUVmax. CONCLUSION Characteristics of an aseptic vascular stent graft in the aorta and iliac vessels on 18F-FDG PET/CT include graft SUVmax values within 10%-20% of the ascending aorta background SUVmax. The SUVmax of older aseptic grafts can be as much as 30% above background. The visual uptake pattern of diffuse, homogeneous uptake less than liver was seen in 98% of aseptic vascular grafts, making this pattern particularly reassuring for clinicians.

Abstract
OBJECTIVE To evaluate and compare the outcomes of Candida- and non-Candida-associated aortic graft infections. METHODS We retrospectively analyzed the data from patients treated for aortic graft infection from 2015 to 2021 in our hospital. RESULTS A total of 66 patients (56 men; median age, 69 years; range, 50-87 years) were admitted with aortic graft infection, including 21 (32%) patients in the Candida group and 45 (68%) in the non-Candida group. The average time between initial operation and presentation of aortic graft infection was 50 months (range, 1-332 months). Graft-enteric fistulas (GEFs) were more often in the Candida group (57% vs 27%, P = .017). The most proven causative fungal specimen was C. albicans in 16 (76%) patients. Non-albicans Candida was found in 9% of all patients and 29% of the Candida patients. The median ICU length of stay was longer in the Candida group than non-Candida (10 vs 9 days, P = .012). Additionally, the median hospital length of stay was longer in the Candida group (33 vs 22 days, P = .048). There were no statistically significant differences between Candida and non-Candida groups according to the in-hospital mortality (24% vs 24%, P = .955), and 1-year mortality (38% vs 38%, P = .980). CONCLUSIONS Patients with bacterial and fungal aortic graft infections have high rates of morbidity and mortality. We found no significant differences in postoperative morbidity and mortality between Candida and non-Candida patients. However, the ICU and hospital length of stay were longer in the Candida group.

Abstract
AbstractWe report an extremely rare case of primary aortocaval fistula with simultaneous development of an aortoenteric fistula in a 68-year-old man. The patient developed under oral anticoagulation a spontaneous intracaval aortic rupture. An emergency intervention was performed with a covering of the fistula with an aorto-uniiliac stent graft and a femoro-femoral crossover bypass. One week later, the patient was transferred to our institution with the diagnosis of a psoas abscess and a suspected concomitant aortoenteric fistula. We performed a complete explantation of the endograft and implanted it after extensive debridement an aortobiiliac bypass, made of bovine pericardium. The postoperative course was complicated, first by bleeding from the left iliac anastomosis, and then by bleeding from the proximal aortic anastomosis. The entire graft was explanted and an axillo-femoral bypass was implanted. The patient then developed a multi-organ failure and died 3 months later. If possible, an extended surgical debridement and resection of all infected tissue with in situ reconstruction is the gold standard. However, with this therapy, there is still a high risk of reinfection. Long-term antibiotic management is mandatory.

Deep Femoral Vein Reconstruction for Abdominal Aortic Graft Infections is Associated with Low Aneurysm Related Mortality and a High Rate of Permanent Discontinuation of Antimicrobial Treatment. Eur J Vasc Endovasc Surg 2021; 62:927-934. [PMID: 34686449 DOI: 10.1016/j.ejvs.2021.09.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 07/16/2021] [Accepted: 09/05/2021] [Indexed: 11/20/2022]
Abstract
OBJECTIVE Aortic prosthesis infection is a devastating complication of aortic surgery. In situ reconstruction with the neo-aorto-iliac system (NAIS) bypass technique has become increasingly used and is recommended in recent treatment guidelines. The main aim was to evaluate NAIS procedural outcomes when undertaken after previous open or endovascular aortic repair in Sweden. METHODS In this retrospective study, The National Quality Registry for Vascular Surgery (Swedvasc) was used to identify Swedish centres that offered the NAIS bypass procedure for aortic prosthesis infection between 2008 and 2018. Variables of special interest were procedural details, short and long term survival, renal and other complications, and the durtion of antimicrobial treatment. RESULTS Forty patients (36 males, four females [mean age 69 years], 32 open repairs, seven endovascular aortic repairs [EVAR] and one fenestrated EVAR; 21 presented with aorto-enteric fistula) operated on with NAIS bypass were reviewed. The median time from the primary aortic intervention to the NAIS bypass procedure was 32 months (range 0 - 252 months). Mean ± standard deviation operating time was 645 ± 160 minutes, mean blood loss was 6 277 ± 6 525 mL, mean length of intensive care unit stay was 5.3 ± 3.7 days, and mean length of overall hospital stay was 21.2 ± 11.4 days. Thirty-five patients (88%) had a positive microbial culture; the most commonly isolated pathogen was Candida spp. The majority of patients survived for 30 days (n = 35 [88%]), and 33 (83%) and 32 (80%) patients survived for 90 days and one year, respectively. The number of surviving patients free from antimicrobial treatment at 90 days, six months, and one year was 19 (58%), 29 (88%), and 30 (94%). After a mean long term follow up of 69.9 ± 44.7 months, 20 patients were still alive. CONCLUSION The NAIS bypass procedure offered reasonable survival and functional outcomes, and was associated with a high cure rate, defined as freedom from any antimicrobial treatment.

Treatment and Outcomes of Aortic Graft Infections Using a Decision Algorithm. Ann Vasc Surg 2021; 76:254-268.

Abstract
BACKGROUND Aortic graft infection (AGI) is a rare but devastating complication requiring both explant of the infected prosthesis and lower extremity revascularization. Despite a variety of methods to treat AGI, there is a paucity of evidence that describes comparative outcomes. Moreover, controversy exists surrounding what the optimal repair strategy is with limited descriptions of how these techniques should be employed in this complex group of patients. Therefore, the purpose of this analysis was to review our experience with AGI management while highlighting a practice philosophy that can achieve acceptable outcomes. METHODS All AGI patients between 2002-2019 were reviewed. The primary end-point was 30-day mortality. Secondary end-points included complications, re-infection, unplanned re-operation and all-cause mortality. Kaplan-Meier methodology was used to estimate time to events. Cox regression models were employed to identify association between patient factors and operative strategy with survival. Subgroup analysis included outcome comparison among four different operative approaches(extra-anatomic bypass with aortic ligation [EAB] and in-situ reconstruction [ISR] using either NAIS, cryopreserved allograft [Cryo], or antibiotic-soaked prosthetic grafts [Other]). RESULTS 142 patients (male-69%, mean age 67 ± 11 years) were reviewed. Median time to AGI presentation was 52 (IQR 16-128) months. ISR was performed in 70% (n = 99)[ISR: NAIS-49% (n = 49), Cryo, 33% (n = 33) and Other-23% (n = 23)]. EAB was used in 26% (n = 37), of which 57% (n = 21) were staged repairs[no reconstruction, 4%: intraoperative death-2, AGI removal without reconstruction-2]. A graft enteric erosion/fistula was identified in 39% (n = 55). Mean follow-up time was 14 ± 27 (median 2.2[IQR 0.1-16]) months. Overall, 30-day mortality was 21% and 69% (n = 98) experienced a complication. The most common complications were pulmonary (35%;n = 50), vascular (28%;n = 39), gastrointestinal (22%;n = 31) and renal (21%;n = 30). Freedom from re-infection at one and three years was 78 ± 5% and 73 ± 6% while freedom from unplanned re-operation was 50 ± 5% and 40 ± 6%, respectively. Corresponding one- and five-year freedom from all-cause mortality was 67 ± 4% and 53 ± 4%. When stratified by the four different repair strategies, unadjusted rates of postoperative complications and mortality were not different. However, EAB patients had more renal complications. All-cause mortality predictors included age (HR 1.04, 95%CI 1.01-1.1; P = 0.003), CHF (HR 2.7, 1.3-5.7; P = 0.01), and graft enteric erosion/fistula (HR 2.2, 1.3-3.8;P = 0.005) while total graft excision was protective (HR 0.34, 0.2-0.7; P = 0.003). CONCLUSIONS AGI repair, regardless of operative strategy, results in significant early morbidity, and mortality. The need for unplanned re-operation is common; however, long-term survival is acceptable in appropriately selected patients. Re-infection risk mandates life-long surveillance and consideration of indefinite anti-microbial suppression in certain subgroups. Due to the complexity and intensity of care, all AGI should be treated, when possible, at centers performing high-volume aortic surgery.

Abstract
The term 'aortitis' comprises a heterogeneous spectrum of diseases, with varied etiology and clinical presentations, whose common characteristic is the inflammation of the aortic wall. Since aortitis can mimic almost all common cardiovascular disorders, its clinical recognition remains a challenge. Some cases of aortitis remain undetected for a long time and may be diagnosed after severe life-threatening complications have already arisen. The diagnosis of aortitis is based on the presence of homogeneous circumferential thickening of the aortic wall detected on aortic imaging, or typical histological features in combination with clinical findings and laboratory parameters. Management of aortitis is usually conservative (immunosuppressive drugs in noninfectious aortitis; antimicrobial drugs in infectious). However, if vascular complications such as aortic aneurysm, rupture, or steno-occlusive events appear, aortic surgery or endovascular therapy may be required. This review article summarizes the current knowledge regarding the etiology, clinical presentation, diagnosis, and treatment of inflammatory diseases of the aorta to promote better clinical management of these entities.

Aortoduodenal fistulas after endovascular abdominal aortic aneurysm repair and open aortic repair. J Vasc Surg 2021; 74:711-719.e1. [PMID: 33684467 DOI: 10.1016/j.jvs.2021.02.027] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 02/11/2021] [Indexed: 11/23/2022]
Abstract
OBJECTIVE In the present study, we have reported and compared aortoduodenal fistulas (ADFs) after endovascular abdominal aortic aneurysm repair (EVAR) vs after open aortic repair (OAR). METHODS We retrospectively analyzed the data from patients treated for ADFs from January 2015 to May 2020 in our hospital. The clinical data, diagnostic procedures, and surgical options were evaluated. The primary endpoints of the present study were 30-day and 1-year mortality. The secondary endpoints were major postoperative complications. RESULTS A total of 24 patients (20 men; median age, 69 years; range, 53-82 years) were admitted with ADFs after EVAR (n = 9) or OAR (n = 15). These patients accounted for ∼4.3% of all abdominal aortic aneurysm repairs in our hospital. The median interval from the initial aortic repair and the diagnosis of ADF was 68 months (range, 6-83 months) for the ADF-EVAR group and 80 months (range, 1-479 months) for the ADF-OAR group. Three patients in the ADF-EVAR group had refused surgical treatment owing to their high surgical risk. One patient in the ADF-OAR group had undergone removal of the aortic prosthesis without replacement. Of the remaining 20 patients, 12 (ADF-EVAR group, n = 4; ADF-OAR group, n = 8) had undergone in situ replacement of the aorta and 8 (ADF-EVAR group, n = 2; ADF-OAR group, n = 6) had undergone extra-anatomic reconstruction with aortic ligation. After a mean follow-up of 26 months, no patient had experienced early limb loss. However, one case of rupture of the venous graft (ADF-EVAR), one case of aortic stump blowout (ADF-OAR), and one case of a ureteroarterial fistula with a homograft (ADF-OAR) had occurred. Overall, the incidence of postoperative complications was significantly greater after ADF-OAR (93% vs 33%; P = .036). The most frequent bacteria involved in the blood cultures were Escherichia coli (25% of patients), and Candida spp. (61%) were the predominant pathogens found on intra-abdominal smears. The in-hospital mortality rates for the ADF-EVAR and ADF-OAR group were 22% and 13%, respectively. The corresponding 1 -year mortality rates were 22% and 33%. CONCLUSIONS Patients with ADFs after EVAR or OAR have limited overall survival. In addition to the similar therapeutic approaches, we found no significant differences in postoperative mortality between these two uncommon pathologic entities. In our study, the overall postoperative morbidity seemed greater for the ADF-OAR group.

Abstract
Endovascular graft infection is a rare but challenging complication that requires a tailored approach to remove the infected graft and restore the arterial circulation combined with long-term antibiotic therapy. We present a case surgically treated with explant of the graft and reconstruction of the thoracoabdominal aorta. Microbiological investigation revealed growth of
Neisseria meningitidis
, which is extremely rare in this location, and to our knowledge, has not been previously published in the literature.

Abstract
Introduction Alarming outcomes have been reported following infected endovascular aortic aneurysm repair (EVAR) device explantation. Infected fenestrated EVAR (FEVAR) exposes patients to even worse procedural risks. Report A 67 year old man with a prior history of FEVAR presented with impaired general condition, abdominal and back pain, and increased C reactive protein. Computed tomography angiography revealed a collection around the aortic graft bifurcation and 18F-fluorodeoxyglucose–positron emission tomography (FDG-PET) revealed increased FDG uptake at this level, confirmed by labelled white blood cells, all favouring graft infection. A thoracophrenolumbotomy was performed and revealed an aorto-enteric fistula which was treated by small bowel resection. The left renal artery was transected at the distal end of the bridging stent and a thoracorenal bypass was performed. The thoracic aorta was cross clamped above the coeliac trunk for complete graft excision. Meanwhile, the right kidney was perfused with 4°C Ringer lactate solution. In situ reconstruction was accomplished with a bifurcated antimicrobial graft sutured below the superior mesenteric artery with re-implantation of the right renal artery. The patient was left with a laparostomy for definitive abdominal closure, restoration of the digestive tract, and omental wrap 72 hours later. Broad spectrum antibiotic therapy was initiated peri-operatively and reduced to sulfamethoxazole/trimethoprim for a total duration of six weeks after one sample was positive for Moraxella osloensis. Eleven months later, the patient was free from re-infection, with no fever or inflammatory syndrome. Discussion Total explantation of stent grafts with tissue debridement and post-operative antibiotic therapy is the gold standard when dealing with infected EVAR. As with type IV thoraco-abdominal aneurysm open repair, FEVAR device explantation requires additional protective measures to prevent visceral ischaemia and renal impairment. In agreement with the European Society for Vascular Surgery guidelines, such patients should be referred to dedicated vascular centres with expertise in surgical repair, anaesthetics, and post-operative intensive care. Alarming outcomes have been reported following infected endovascular aortic aneurysm repair (EVAR) explantation. Total explantation of stent grafts with tissue debridement and post-operative antibiotic therapy is the gold standard. FEVAR explantation requires additional protective measures to prevent visceral ischaemia and kidney impairment.

Abstract
We describe the successful medical management of an infected aorto-bi-Iliac endograft. In this case report, we provide an example of a patient with an infected aorto-bi-iliac endograft and how appropriate medical management may result in a positive outcome. We report a case of a 67-year-old man with several medical comorbidities who developed aorto-bi-iliac endograft infection one year after graft placement. The patient presented to our E.R. with fever, lethargy, tachycardia, tachypnea, and hypotension. The diagnosis of an infected endograft was established after excluding any other possible source of infection plus the strong radiological evidence by computed tomographic scan and WBCs labeled Indium-111 tropolone scan. Blood cultures revealed the development of Eggerthella lenta, Escherichia coli Extended-spectrum beta-lactamase (ESBL), and Enterococcus Faecalis. To our knowledge, this is a rare case of an infected endograft and bacteremia due to Eggerthella lenta. After the administration of vancomycin and Meropenem, no improvements were noted to the patient’s clinical condition. However, upon the administration of Tigecycline, the patient’s clinical condition improved. Two days later, repeat blood cultures were negative. After completion of the course of antibiotics and stabilization of other comorbidities, the patient was discharged home with long term antibiotic therapy under close control of inflammation markers.

Long-term Efficacy of EVAR in Patients Aged Less Than 65 Years with an Infrarenal Abdominal Aortic Aneurysm and Favorable Anatomy. Ann Vasc Surg 2020; 67:283-292. [PMID: 32283305 DOI: 10.1016/j.avsg.2020.03.038] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2020] [Revised: 03/21/2020] [Accepted: 03/22/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND The aim of this study was to compare early and long-term outcomes of endovascular aneurysm repair (EVAR) versus open surgical repair (OSR) in patients aged ≤ 65 years. METHODS Data of patients aged ≤65 years undergoing infrarenal abdominal aortic aneurysm repair, between 2005 and 2013, were retrospectively reviewed. All EVAR procedures were performed according to the instruction for use, and only OSR procedures with an infrarenal aortic cross-clamping were included in the study. RESULTS In this group of 115 patients (EVAR: 58 patients, 51% and OSR: 57 patients, 49%), EVAR and OSR patients had similar comorbidities, except for obesity (EVAR: 38% vs. OSR: 19%; P = 0.03). A stay in the intensive care unit (ICU) was necessary in 19% of patients with EVAR versus 79% with OSR (P = 0.001), and the amount of blood transfusion was 236 ± 31 mL for EVAR versus 744 ± 98 mL for OSR (P = 0.001). The hospital stay was 4 ± 2 days for EVAR versus 9 ± 6 days for OSR (P = 0.03). The overall 30-day mortality was 1% (EVAR: 0% vs. OSR: 2%; P = 0.30). Five patients (4%) required reinterventions within 30 days (EVAR: 0% vs. OSR: 8%, P = 0.001). The mean follow-up was 86 ± 38 months. Freedom from reintervention at 10 years after EVAR was 81% versus OSR 74%; (P = 0.77). Late reinterventions were reported in 13 patients (23%) with OSR and in 10 patients (17%) with EVAR. Postoperative retrograde ejaculation occurred more often in patients with OSR (31%) versus EVAR (2%) (P = 0.001). During the follow-up, cancer was found in 19 (17%) patients with no difference between EVAR and OSR (P = 0.83). The global survival at 10 years was 72% (EVAR: 79% vs. OSR: 70%; P = 0.94). CONCLUSIONS In this study, EVAR was associated with a shorter hospital stay, less need for the ICU, and less early reinterventions than OSR. Survival and reinterventions during the follow-up were not significantly different between EVAR and OSR. According to these results, EVAR may be considered for patients aged ≤65 years with a favorable anatomy.

Approaches to the Salvage of Axillary Bilateral Femoral Bypass in Patients with Claudication due to Demand Ischemia. Ann Vasc Surg 2019; 64:409.e7-409.e9.

Abstract
The axillary bilateral femoral bypass is often utilized as an alternative to in-line aortic reconstruction in patients with multiple medical comorbidities, who would be unable to tolerate open abdominal surgery with an aortic clamp, or patients with mycotic aneurysms, or infected grafts. Idealized fluid mechanics suggest that there would be equal flow in an axillary bilateral femoral bypass when compared to in-line reconstruction. However, in a non-idealized state, friction results in kinetic energy loss and decreased volume flow to the lower extremities in the longer, smaller diameter graft. Although older or less active people may tolerate the lower volume flow of a long segment extra-anatomic bypass, there is growing evidence that a subset of patients will be symptomatic from reduced flow volumes. Here we present 3 patients in whom symptomatic relief was achieved with the addition of a contralateral axillary femoral bypass and ligation of the previous femorofemoral component.

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.

Abstract
BACKGROUND Availability of highly active antiretroviral therapy (HAART) for HIV has prolonged life expectancy of patients but has also increased the incidence of non-AIDS comorbid conditions. Among these, there are cardiovascular diseases, and aortic involvement has been described in patients with HIV in the form of aortitis, aneurysms, or dissections. Our study aims to describe aortic pathology occurring in patients with HIV, focusing on clinical and surgical presentation, management, and outcome, through a review of cases published in literature. METHODS MEDLINE (www.ncbi.nlm.nih.gov/pubmed) database was reviewed for "aortitis" OR "aortic aneurysm" OR "aortic dissection" AND HIV. Research was restricted to English language. Only case reports were included. Data on patients' age, sex, traditional risk factors, timing from HIV diagnosis, pharmacological details, coinfection (syphilis, hepatitis C virus [HCV], and hepatitis B virus [HBV]), anatomical localization of lesion, presence of inflammatory involvement, rapid growing or rupture, and surgical treatment and outcomes were collected and summarized in tables. RESULTS Forty articles (51 cases) were included in the study. The mean age of patients was 48.8 ± 8.3 years. Male sex was preponderant (43 cases, 84.3%). Among traditional risk factors, hypertension and smoking were the most frequently reported ones (14 and 13 cases, respectively), followed by vasculopathy involving other arterial districts, dyslipidemia, diabetes, and drug addiction. In 3 cases, HIV was diagnosed in the same time as aortic pathology, whereas in most cases, aortic event occurred after five years from HIV diagnosis. In 30.5% of cases for which data on pharmacologic management were available, no treatment or poor adherence was reported. Coinfection occurred in some cases (syphilis in 6, HCV in 5, and HBV in 3). As for anatomical involvement, isolated thoracic lesions were more frequent (24, 47.1%), followed by abdominal and thoracoabdominal lesions. The etiology ranged from bacterial mycotic aneurysms to tertiary syphilis, postsurgical complications, or atherosclerosis. In 3 cases, HIV vasculitis was directly suggested, and in another 2, no other potential etiology had been diagnosed through cultural tests. Open surgical treatment was carried out in 30 cases (58.8%), and in addition, 10 endovascular (19.6%) and 2 hybrid procedures were described. Inflammatory features occurred in 7 cases, and a rapid evolution of lesions in 6. In 9 cases (17.6%), rupture occurred. Mortality was reported in 8 cases (15.7%). CONCLUSIONS Aortic pathology may occur in patients with HIV. The entanglement of different patterns of pathological involvement of the aortic wall, secondary to immune dysregulation, infectious process, or atherosclerotic damage that may co-occur in one single case, results in a very challenging management of the condition. Because of the increased life expectancy of patients and immigration from regions with both high HIV and coinfection prevalence, the incidence of aortic pathology could increase in the upcoming years, suggesting the urgent need for further studies to optimize management in these very complex cases.
