RESUMO

Primary aortoenteric fistulas (AEF) are rare. The majority of these are due to atherosclerotic aortic aneurysms. Mycotic aortic aneurysms leading to primary AEF are exceedingly uncommon. Here we report a rare case of primary AEF secondary to Salmonella-related mycotic aneurysm and discuss the diagnostic and therapeutic issues.

RESUMO

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.

RESUMO

INTRODUCTION: Intracranial mycotic or infectious aneurysms result from the infection of arterial walls, most caused by bacterial or fungal organisms. These infections can weaken the arterial wall, leading to the formation of an aneurysm, a localized dilation, or a bulge. The management can be conservative mainly based on antibiotics or invasive methods such as clipping or endovascular treatment. PURPOSE: We performed a systematic review and meta-analysis of the current literature on endovascular treatment of mycotic aneurysms, analyzing the safety and efficacy associated with this procedure. METHODS: We systematically searched on PUBMED, Cochrane Library, Embase, and Web of Science databases. Our search strategy was carefully crafted to conduct a thorough investigation of the topic, utilizing a comprehensive combination of relevant keywords. This meta-analysis included all studies that reported endovascular treatment of mycotic aneurysms. To minimize the risk of bias, studies with fewer than four patients, studies where the main outcome was not found, and studies with no clear differentiation between microsurgical and endovascular treatment were excluded. RESULTS: In a comprehensive analysis of 134 patients, it was observed that all except one patient received antibiotics as part of their treatment. Among the patients, 56% (a total of 51 out of 90 patients) underwent cardiac surgery. Additionally, three patients required a craniotomy following endovascular treatment. 12 patients experienced morbidity related to the procedures performed, indicating complications arising from the interventions. Furthermore, four aneurysms experienced rebleeding while treatment. A pooled analysis of the endovascular treatment of the mycotic aneurysm revealed a good level of technical success, achieving a 100% success rate in 12 out of 14 studies (97-100%; CI 95%; I2 = 0%), as illustrated in Fig. 2. Similarly, the aneurysm occlusion rate demonstrated a notable efficacy, with a success rate of 97% observed in 12 out of 14 studies (97-100%; CI 95%; I2 = 0%), as depicted in Fig. 3. CONCLUSION: The results strongly support the efficacy of endovascular treatment in achieving technical success, complete aneurysm occlusion, and favorable neurological outcomes. Additionally, the notably low incidence of complications and procedure-related mortality reaffirms the safety and benefits associated with this intervention.

RESUMO

HIV-associated infective native aortic aneurysms (INAA) constitute a subcategory of the disease INAA. This is a very rare group of patients. The aim of this systematic literature review was to compile a description of patient characteristics with HIV-associated INAA. A systematic literature review was performed using the search terms HIV and aortic aneurysm in Ovid MEDLINE and Embase databases, on articles published between 1981 and 2022. Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement, articles were scrutinized according to a predefined protocol including age, sex, comorbidities, microbiological pathogens, CD4-count, HIV/AIDS state, aortic segment involved, treatment and outcome. Thirty-three studies, all case reports with a total of 39 patients, were included. The median age was 48 years (range 27-79), most were male n = 35 (90%), and the median follow-up was n = 6 months (range 0-63). Cardiovascular comorbidity was present in n = 1 (3%), median CD4-count was 216 (range 6-1236), and n = 12 (31%) had AIDS. The most common microbiological pathogens were Treponema pallidum, n = 12 (31%), Salmonella spp. n = 10 (26%), Mycobacterium species n = 5 (12%) and Staphylococcal spp. n = 5 (13%). The HIV-associated INAAs were localized in the abdominal aorta n = 32 (82%), in the thoracic aorta n = 5 (13%) and in the thoraco-abdominal aorta n = 2 (5%). Open surgery was performed in n = 23 (59%) patients, endovascular aortic repair n = 6 (15%), and n = 7 (18%) did not receive surgery. Infection-related complications were reported in n = 2 (7%) patients, both with postoperative development of fatal sepsis. Patients with HIV-associated INAAs were younger, had lower rate of cardiovascular comorbidity, demonstrated low CD4 counts as a measure of immunosuppression, and demonstrated diverse microbiological pathogens compared with other INAAs. Treponema pallidum and Mycobacterium spp. were common pathogens, which are very rare microbiological pathogens in other INAAs.

RESUMO

BACKGROUND: It is challenging to diagnose infected aneurysm in the early phase. This study aimed to describe the clinical and microbiological characteristics of infected aneurysm, and to elucidate the difficulties in diagnosing the disease. METHODS: Forty-one cases of infected aneurysm were diagnosed in Nagasaki University Hospital from 2005 to 2019. Information on clinical and microbiological characteristics, radiological findings, duration of onset, and type of initial computed tomography (CT) imaging conditions were collected. Factors related to diagnostic delay were analyzed by Fisher's exact test for categorical variables or by the Wilcoxon rank-sum test for continuous variables. RESULTS: Pathogens were identified in 34 of 41 cases; the pathogens were Gram-positive cocci in 16 cases, Gram-negative rods in 13 cases, and others in five cases. Clinical characteristics did not differ in accordance with the identified bacteria. At the time of admission, 16 patients were given different initial diagnoses, of which acute pyelonephritis (n = 5) was the most frequent. Compared with the 22 patients with an accurate initial diagnosis, the 19 initially misdiagnosed patients were more likely to have been examined by plain CT. The sensitivities of plain CT and contrast-enhanced CT were 38.1% and 80.0%, respectively. CONCLUSIONS: In cases of infected aneurysm, diagnostic delay is attributed to non-specific symptoms and the low sensitivity of plain CT. Clinical characteristics of infected aneurysm mimic various diseases. Contrast-enhanced CT should be considered if infected aneurysm is suspected.

RESUMO

OBJECTIVE: Mycotic/infective native aortic aneurysms (INAA) are managed heterogeneously. In the context of disparate literature, this study aimed to assess the outcomes of INAA surgical management and provide comprehensive data in alignment with recent suggestions for reporting standards. METHODS: A retrospective review of patients presenting with INAA from September 2002 to March 2020 at two institutions was conducted. In hospital mortality, 90 day mortality, overall mortality, and infection related complications (IRCs) were the study endpoints. Overall survival and IRC free survival were estimated, and predictors of mortality tested using uni- and multivariable analyses. RESULTS: Seventy patients (60 men [86%], median age 68 years [range 59 - 76 years]) were included. Twenty (29%) were ruptured at presentation. INAA location was thoracic in 11 (16%) cases, thoraco-abdominal in seven (10%), and abdominal in 50 (71%). Half of the abdominal INAAs were suprarenal. Two INAAs were concomitantly abdominal and thoracic. Pathogens were identified in 83%. The bacterial spectrum was scattered, with rare Salmonella species (n = 6; 9%). Open surgical repair was performed in 66 (94%) patients, including five conversions of initially attempted endovascular grafts (EVAR), three hybrid procedures, and one palliative EVAR. Vascular substitutes were cryopreserved arterial allografts (n = 67; 96%), prosthesis (n = 2), or femoral veins (n = 1). Kaplan-Meier estimates of overall survival at 30 and 90 days were 87% (95% confidence interval [CI] 76.6 - 93.0) and 71.7% (95% CI 59.2 - 80.9), respectively. The overall in hospital mortality rate was 27.9% (95% CI 1.8 - 66.5). IRCs occurred in seven (10%) patients. The median follow up period was 26.5 months (range 13.0-66.0 months). Chronic kidney disease (CKD) was independently related to in hospital mortality (odds ratio [OR] 20.7, 95% CI 1.8 - 232.7). American Society of Anesthesiologists score of 3 (OR 6.0, 95% CI 1.1 - 33.9), 4 (OR 14.9, 95% CI 1.7 - 129.3), and CKD (OR 32.0, 95% CI 1.2 - 821.5) were related to 90 day mortality. CONCLUSION: Surgical INAA management has significant mortality and a low re-infection rate. EVAR necessitated secondary open repair, but its limited use in this report did not allow conclusions to be drawn.

RESUMO

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.

RESUMO

Mycotic aneurysms arise from infection of an arterial wall secondary to septic emboli from endocarditis. Although rare, most mycotic aneurysms involve the abdominal aorta, with Staphylococcus aureus and Salmonella spp being the most common causative organisms. We report a case of an 81-year-old woman with a ruptured mycotic popliteal aneurysm from Haemophilus influenzae infection.

RESUMO

OBJECTIVE: The aim was to describe the microbiology of surgically treated infective native (mycotic) aortic aneurysms (INAAs), and associated survival and development of infection-related complications (IRCs). METHODS: Data were pooled from 2 nationwide studies on surgically treated patients with INAAs in Sweden, between 1994 - 2016. Patients were grouped and analyzed according to culture results: 1) Staphylococcus aureus, 2) Streptococcus species (sp.), 3) Salmonella sp., 4) Enterococcus sp., 5) Gram-negative intestinal bacteria, 6) Other sp. (all other species found in culture), and 7) Negative cultures. RESULTS: A sum of 182 patients were included, mean age 71 years (standard deviation; SD: 8.9). The median follow-up was 50.3 months (range 0 - 360). 128 (70.3%) patients had positive blood and/or tissue culture; Staphylococcus aureus n = 38 (20.9%), Streptococcus sp. n = 37 (20.3%), Salmonella sp. n = 19 (10.4%), Enterococcus sp. n = 16 (8.8%), Gram-negative intestinal bacteria n = 6, (3.3%), Other sp. n = 12 (6.6%) and Negative cultures n = 54 (29.7%). The estimated survival for the largest groups at 2-years after surgery was: Staphylococcus aureus 62% (95% Confidence interval 53.9 - 70.1), Streptococcus sp. 74.7% (67.4 - 82.0), Salmonella sp. 73.7% (63.6 - 83.8), Enterococcus sp. 61.9% (49.6 - 74.2), and Negative cultures 89.8% (85.5 - 94.1), P = .051. There were 37 IRCs (20.3%), and 19 (51.4%) were fatal, the frequency was insignificant between the groups. The majority of IRCs, 30/37 (81%), developed during the first postoperative year. CONCLUSION: In this assessment of microbiological findings of INAAs in Sweden, 50% of the pathogens were Staphylococcus aureus, Streptococcus sp., or Salmonella sp.. The overall 20%-frequency of IRCs, and its association with high mortality, motivates long-term antibiotic treatment regardless of microbial findings.

RESUMO

BACKGROUND: Bacillus Calmette-Guerin (BCG) is a live, attenuated strain of Mycobacterium bovis that is used in the treatment of non-muscle invasive bladder cancer (NMIBC). Vascular complications, including mycotic aneurysms, after BCG therapy are exceedingly rare. In this patient population, the diagnosis of mycotic aneurysms can be delayed or missed due to their non-specific clinical and radiologic presentation. Literature review reveals management of mycotic aneurysms attributable to BCG therapy is widely varied.2,5-8,12,15 CASE REPORT: We report a patient who presented with mycotic aneurysm formation secondary to BCG treatment for bladder cancer that was repaired with in-line reconstruction utilizing cryoartery and buttressed with omental flap. We suggest this as an alternative treatment to in-line prosthetic graft or extra-anatomic reconstruction.

RESUMO

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.

RESUMO

The aim of this article is to present a case of mycotic aneurysm of internal carotid artery secondary to livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) treated with resection and common-to-internal carotid artery bypass with autologous vein graft in a male pig farmer. A 69-year-old man, pig farmer, with recent dental extraction was admitted with a right cervical pulsatile mass, dysphonia, pain, leukocytosis and elevated C-reactive protein (CRP). Ultrasonography (US) and computed tomography angiography (CTA) showed a 3.9 × 4.5 cm mycotic aneurysm of right internal carotid artery with hypermetabolic uptake in positron emission tomography (PET) scan. Resection of the mycotic aneurysm and a common-to-internal carotid artery bypass with major saphenous vein graft were performed. LA-MRSA clonal complex (CC) 398 was detected in intraoperative samples and antibiotic therapy was changed according to antibiogram. Patient was discharged at the seventh postoperative day and received antibiotic therapy for 6 weeks. US 12 months later showed patency of the bypass without collections. Mycotic aneurysms of internal carotid artery are very infrequent. MRSA isolation is rare, and to the best of our knowledge this is the first case caused by multi-drug resistant LA-MRSA CC398. The treatment includes mycotic aneurysm resection and reconstruction with venous graft bypass plus intensive antibiotic therapy.

RESUMO

BACKGROUND: Mycotic aortic aneurysm is a rare and potentially life-threatening lesion, and endovascular repair has become increasingly accepted for intervention. Fenestrated endografts are available options to treat aneurysms involving visceral arteries. Here, we first report two patients with mycotic aortic aneurysm involving paraviscereal aorta who were successfully treated with custom-made fenestrated endograft. CASE PRESENTATION: Two patients were presented with mycotic aortic aneurysm. Due to their comorbidities and the involvement of the renal arteries, company-manufactured fenestrated stents were designed. Meanwhile, antibiotic therapy was administrated for 2 months before endovascular repair. Patients improved well without complications. CONCLUSIONS: Custom-made fenestrated endovascular stent is an effective and feasible alternative solution to mycotic paravisceral aorta aneurysm.

RESUMO

Profunda femoris aneurysms account for only 0.5% of all peripheral artery aneurysms. This case documents a profunda femoris mycotic aneurysm (MA) in a 47-year-old woman, three years post-treatment of bacterial endocarditis. The patient underwent an open surgical excision of the aneurysm with antibiotic cover and made a successful recovery. A literature review was carried out to look at other MA cases to summarise the most common presentations, infective agents and management strategies.

RESUMO

BACKGROUND: Bacteroides dorei is an anaerobic gram-negative bacterium first described in 2006. Because of the high similarity in mass spectra between B. dorei and Bacteroides vulgatus, discriminating between these species is arduous in clinical practice. In recent decades, 16S rRNA gene sequencing has been a complementary method for distinguishing taxonomically close bacteria, including B. dorei and B. vulgatus, at the genus and species levels. Consequently, B. dorei has been shown to contribute to some diseases, including type 1 autoimmune diabetes mellitus and atherosclerotic diseases. However, there are no reports on invasive infectious diseases caused by B. dorei. This report describes the first case of direct invasion and colonisation of human tissue by B. dorei, thus providing a warning regarding the previously proposed application of B. dorei as a live biotherapeutic for atherosclerotic diseases. CASE PRESENTATION: A 78-year-old Japanese man complained of intermittent chest/back pain and was diagnosed with a mycotic thoracic aortic aneurysm by enhanced computed tomography on admission. Despite strict blood pressure control and empirical antibiotic therapy, the patient's condition worsened. To prevent aneurysmal rupture and eliminate infectious foci, the patient underwent surgical treatment. The resected specimen was subjected to tissue culture and 16S rRNA gene sequencing analysis to identify pathogenic bacteria. A few days after the surgery, culture and sequencing results revealed that the pathogen was B. dorei/B. vulgatus and B. dorei, respectively. The patient was successfully treated with appropriate antibacterial therapy and after improvement, was transferred to another hospital for rehabilitation on postoperative day 34. There was no recurrence of infection or aneurysm after the patient transfer. CONCLUSIONS: This report describes the first case of invasive infectious disease caused by B. dorei, casting a shadow over its utilisation as a probiotic for atherosclerotic diseases.

RESUMO

We report the case of a 48-year-old man, admitted for atrial fibrillation with rapid heart rate and intense chest pain. A quick evaluation revealed a giant aortic aneurysm with severe aortic regurgitation and pericardial fluid without a trace of aortic dissection. Because of high suspicion of aortic rupture, an emergency surgery was planned, and a Bentall procedure was performed. On examination of the aortic wall revealing vertical wrinkling with a tree bark aspect, suspicion of syphilitic aortitis arose. The diagnosis was confirmed through postoperative serologic testing and histological examination. Histopathologic differential diagnosis, special treatment and follow-up are presented.

RESUMO

OBJECTIVES: The aim of this study is to assess any relation between spondylitis and aortic aneurysmal disease by reviewing the current literature. METHODS: A systematic search was undertaken using MEDLINE, EMBASE and CENTRAL databases till May 2019, for articles reporting on patients suffering from spondylitis and aortic aneurysm. RESULTS: The most involved aortic segment was infrarenal aorta (56.9%). The lumbar vertebrae were more frequently affected (79.7%). Commonest symptoms were back pain (79.1%), fever (33.7%) and lower limb pain (29.1%). 55.8% of cases were diagnosed using computed tomography. The pathology was attributed to infectious causes in 25.1% of cases. 53.4% of patients were treated only for the aneurysm, 27.9% for both pathologies, while two patients solely for the vertebral disease. Endovascular aneurysm repair was chosen in 12.8% of cases. The 30-day mortality was 8.1% (7/86); mostly from vascular complications. CONCLUSIONS: A synchronous spondylitis and aortic aneurysm may share common etiopathology, when an infectious or inflammatory cause is presented. The lumbar vertebrae are more frequently affected. Low quality data do not allow safe conclusion to suggest the best treatment option.
