RESUMO
Mycotic aneurysm in a visceral artery due to tuberculosis (TB) is a rare occurrence. Imaging plays a critical role in its diagnosis. Over the last few years, minimally invasive interventional radiological treatment has replaced more invasive surgical procedures. Here, we report a case presenting with abdominal pain, diagnosed with jejunal artery mycotic pseudoaneurysm (PSA) secondary to TB, managed by endovascular coiling. Coil embolisation of the superior mesenteric artery branch was done using three coils, closing both the front door, back door and sac of the mycotic aneurysm. Visceral PSA following TB infection is rare and can be fatal if left untreated. Coil embolisation is a minimally invasive procedure with a high success rate and comparatively fewer complications.

Infective native arterial aneurysms and inflammatory aortic aneurysms are rare but morbid pathologies seen by vascular surgeons in the emergency setting. Presentation is not always clear, and a full workup must be obtained before adopting a management strategy. Treatment is multidisciplinary and is tailored to every case based on workup findings. Imaging with computed tomography, magnetic resonance, or with fluorodeoxyglucose-positron emission tomography aids in diagnosis and in monitoring response to treatment. Open surgery is traditionally performed for definitive management. Endovascular surgery may offer an alternative treatment in select cases with acceptable outcomes. Neither technique has been proven to be superior to the other. Physicians should consider patient's anatomy, comorbidities, life expectancy, and goals of care before selecting an approach. Long-term pharmacological treatment, with antibiotics in case of infective aneurysms and immunosuppressants in case of inflammatory aneurysms, is usually required and should be managed in collaboration with infectious disease specialists and rheumatologists.

We aimed to analyze the feasibility of endovascular treatment for brucellosis-related aorta-iliac artery pseudoaneurysm. We did a statistical analysis that among the 11 cases, the thoracic aorta was involved in 3 cases, the abdominal aorta was involved in 6 cases, and the iliac artery was involved in 2 cases. Five patients had a history of contact with cattle and sheep, 3 had a history of drinking raw milk, 10 patients had a fever before the operation, and 11 patients had positive serum agglutination test. Blood culture was positive in 2 patients. All patients were given anti-brucellosis treatment immediately after diagnosis. One died of aortic rupture 5 days after emergency endovascular gastrointestinal bleeding. Endovascular-covered stent implantation and active anti-brucellosis therapy were used to treat 10 patients. The follow-up period was 8 years without aortic complications or death for all patients. We think early diagnosis and a combination of anti-brucellosis drugs and endovascular therapy may be the first choice for treating the pseudoaneurysm caused by Brucella.

Infective native aneurysms (INA) of the infrapopliteal arteries are rare and have previously been poorly described. This systematic review aims to provide an overview of the literature of this entity. Furthermore, two case reports of our own clinical experience are presented. PubMed, ScienceDirect, Cochrane, Ovid Embase, Ovid MEDLINE, and Web of Science were searched for articles on INAs of the infrapopliteal segment from January 1990 to September 2023. Article screening and selection were performed adhering to PRISMA guidelines. A total of 98 articles were screened and 20 were eligible for inclusion, of which all were case reports. In total, 22 patients with 28 infrapopliteal INAs were identified. The majority of INAs were located in the tibioperoneal trunk (n = 10, 36%) followed by the posterior tibial artery (n = 7, 25%). A current, or history of, infective endocarditis (IE) was described in 18 out of 22 patients (82%). Two patients died during hospitalization and one patient required a transfemoral amputation. A conservative antibiotic-only approach was chosen in three out of 28 INAs, two of which were the case reports described in this article; surgical or endovascular intervention was performed in 19 out of 28 aneurysms. No complications occurred in the conservative group, but one complication (transfemoral amputation) occurred in the interventional group. Infrapopliteal INA is a rare entity, and most described cases are precipitated by IE. Surgery or endovascular treatment might be indicated, but more research is warranted to define which patient would benefit and by what surgical approach.

BACKGROUND: Hepatic artery aneurysms (HAAs), albeit rare in infective endocarditis (IE), are associated with a life-threatening morbidity. METHODS: Retrospective review of 10 HAA-IE patients based on a total of 623 IE patients managed in 2 institutions (2008-2020) versus 35 literature cases. RESULTS: In our patient population, HAAs (10 males, mean age 48) were incidentally found during IE workup. All were asymptomatic. IE involved mitral (n = 6), aortic (n = 3), or mitral-aortic valve (n = 1). Predisposing factors for IE were as follows: prosthetic valve (n = 6), previous IE (n = 2), IV drug user (n = 1). Streptococcus species (spp.) were predominant (n = 4), then staphylococcus spp (n = 2) and E. faecalis (n = 2). All patients presented associated lesions: infectious aneurysms (n = 5), emboli (n = 9), abscesses (n = 5), and spondylitis/spondylodiscitis (n = 2). HAA patterns on abdominal CT angiography (CTA) were solitary (70%), mean diameter 11.7 mm (range 2-30), intrahepatic location (100%) involving the right HA in 9 out of 10 (90%) patients. In 2 patients, HAAs were complicated (rectorragia and hemobilia in 1, cholestasis in the other). Six patients underwent endovascular hepatic embolization (2 with multiple HAAs). Three HAA-IEs <15 mm resolved under antibiotherapy on abdominal CTA follow-up. All patients underwent cardiac surgery. Late outcome was favorable in all followed patients (5/10). Literature review showed the preponderance of Streptococcus spp., of right lobe and intrahepatic HAA localization. Complications revealed HAAs in patients under antibiotic therapy and/or after cardiac surgery in 17 literature cases of delayed diagnosis. CONCLUSIONS: Abdominal CTA was pivotal in the initial IE workup. Small aneurysms (≤15 mm) resolved under antibiotherapy. The usual treatment modality was HAA embolization and endovascular embolization before valve surgery was safe.

A woman in her 50s presented to the emergency department with 5 days of abdominal pain, nausea and vomiting. CT imaging of her liver demonstrated three enhancing, cystic lesions in her hepatic parenchyma and a large enhancing lesion in her porta hepatis concerning for a hepatic artery aneurysm. Radiographic-guided drainage was performed on two accessible liver abscesses, and cultures from this drainage grew Listeria monocytogenes Serial imaging of the aneurysm demonstrated that the aneurysm spontaneously thrombosed and did not require further intervention. She was subsequently discharged on intravenous ampicillin with a plan to continue until radiographic resolution of the abscesses.

BACKGROUND: Aortic complications after intravesical Bacillus Calmette-Guérin (BCG) application are a rare complication of the treatment of non-muscle invasive bladder cancer. The aim of this systematic review was to perform a descriptive analysis of previously published studies and to discuss the particular challenges of diagnosis and treatment of this rare complication. MATERIAL AND METHODS: A literature search was performed in PubMed (1949-2021) and Web of Science (1900-2021) using the search terms "mycobacterium" OR "bovis" OR "BCG" AND "aorta" OR "aneurysm". In a staged review process, publications with the following inclusion criteria were included in data analysis: original paper, full-text availability in English or German and aortic complication after intravesical BCG instillation. We focused on the analysis of BCG-specific medical history data as well as treatment strategies in relation to patient outcome and the occurrence of graft infections during follow-up. RESULTS: A total of 60 individual cases were described in 55 published articles. BCG-induced mycotic aortic aneurysms can occur in all segments of the thoracoabdominal aorta, but the infrarenal aortic segment was most commonly affected (65% of cases). The most common configuration was saccular outpouchings (65%). Concomitant infections in other tissues were typical (65%). Patients with mycotic aneurysm presented with or without consecutive aortic rupture in 28% and 63%, respectively. Diagnosis was based on a combination of pathological and microbiological examinations. A common treatment algorithm was surgical infection treatment (85%) and antitubercular therapy (83%). Performed simultaneously, they resulted in a long-term survival of 81%. Graft infection after initial aortic repair with alloplastic material (n = 40) developed in ten patients (25%) during follow-up. DISCUSSION: Diagnosis of mycotic aneurysms or vascular complications after intravesical BCG application is exceptionally challenging and a high level of suspicion is required. Diagnosis is based on obtaining sample material of affected regions and the combination of patient's history, clinical presentation and pathological or microbiological examinations. Currently, no consensus guideline for optimal medical treatment options of aortic complications secondary to BCG instillation exists. The combination of surgical treatment and supportive antitubercular therapy seems to achieve the best results. Since the risk of prosthetic infection after the use of alloplastic materials remains high (25%), we strongly suggest evaluating autologous or allogenic aortic replacement during initial aortic repair.

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.

BACKGROUND: Mycotic aortic aneurysm constitutes a potentially devastating disease that necessitates prompt suspicion and diagnosis. There is no exact consensus for treatment, but removal of infected tissues and prolonged use of antimicrobials based on the identified causative microorganisms seem widely acceptable and have been similarly practiced worldwide. However, some patients still show no identified microorganisms. In this study, we sought to determine whether there are any clinical significance or differences of note in culture-negative mycotic aortic aneurysms. METHODS: Between October 2003 and August 2018, 71 patients were identified as treated for mycotic aortic aneurysms at a single tertiary institution. Review of medical records and imaging studies were completed to collect the following information: demographics, previous medical/surgical history regarding potential infection sources, laboratory and radiologic findings, clinical presentations, treatment method, and morbidity and mortality rates. For analysis, patients were categorized into two groups: the blood and/or tissue culture-positive (CP) group and the blood and/or tissue culture-negative (CN) group. The latter was further divided as CN with identified microorganism by molecular biologic methods [CN(+)] and CN with no identified microorganism [CN(-)]. RESULTS: More patients in the CP group were symptomatic than were in the CN(+) group (100% vs. 80%; Pâ¯=â¯0.034). However, identification of causative microorganisms did not result in a difference in symptom status upon comparing the [CPâ¯+â¯CN(+)] and [CN(-)] groups. Inflammatory markers were the most elevated in the CP group and least elevated in the CN(-) group. The aneurysm growth rate seemed slower in the CN(-) group than in the CN(+) and CP groups (1.3 vs. 3.4 vs. 9 mm/month respectively). Aneurysm rupture at initial presentation was more prevalent in the CP group (33.3%). 18F-Fluorodeoxyglucose-positron emission tomography showed increased uptake regardless of whether or not the microorganisms were identified. Early mortality and disease-specific mortality rates during the follow-up period were higher in the CP group but without statistical significance. CONCLUSIONS: Compared with the CP group, the CN groups appeared clinically less severe, and also exhibited a relatively less devastating course as exhibited by the slower aneurysm expansion rate and smaller number of ruptured aneurysms at the initial presentation.

A 58-year-old male underwent an aortic valve replacement due to an acute aortic regurgitation for aortic valve endocarditis. The patient maintained febrile syndrome during the postoperative period, in spite of broad-spectrum antibiotics. The CT scan showed an aneurysmal dilatation (45 mm in diameter) on the right hepatic artery. The appearance of a rapidly growing aneurysmal lesion, which was observed in previous radiologic examinations, suggested a diagnosis of a mycotic aneurysm secondary to infective endocarditis. A selected angiography of the celiac trunk was performed, which confirmed the diagnosis. An endovascular approach was applied and an aneurysm coil embolization was performed. Targeted antibiotic therapy was applied during 6 weeks and the patient showed an improvement and was discharged. He is currently asymptomatic. Discussion Mycotic hepatic artery aneurysms (MHAAs) are uncommon (less than 0.1%) and mainly affect the extrahepatic region (1). In most cases, MHAAs are asymptomatic and a high clinical suspicion is needed. Arteriography is the gold standard and it can be used as a diagnostic and therapeutic tool (2). MHAAs are associated with a high risk of rupture, even in patients without symptoms suggestive of MHAA or previous endocarditis (3). Thus, an early diagnosis and treatment is necessary. Surgery or endovascular techniques may be performed. The endovascular approach is accepted in intrahepatic MHAAs or in high risk patients (1,3). In our patient, a radiological exam was needed due to the persistent febrile syndrome. An endovascular approach was performed after a multidisciplinary team decision.

OBJECTIVE: Mycotic aneurysms of the infrapopliteal vessels are rare, with few cases reported in the literature. Management strategies are diverse and should be tailored to the patient's presentation. METHODS: We describe the case of a 40-year-old male who presented with a painful left leg mass in the setting of bacteremia and infective endocarditis. Imaging revealed an aneurysm of the anterior tibial artery. RESULTS: The patient was treated with antibiotics and open surgical repair with excision of the aneurysmal sac, ligation of the anterior tibial artery, and primary repair of the popliteal artery and tibioperoneal trunk. CONCLUSION: The epidemiology, pathophysiology, and clinical management of infrapopliteal aneurysms are briefly reviewed in this case study.

PURPOSE: The aim of this study is to show the utility of the combination of thrombin and endograft to solve an urgent situation related to femoral infections. CASE: We present the case of a 91-year-old female patient who underwent a femoral endarterectomy and superficial femoral artery angioplasty and developed a surgical site infection. She was readmitted to the hospital because of bleeding and was operated to suture the femoral patch and to do a plasty of sartorius muscle. Six days after the last intervention a femoral pulsatile mass was noted, and the computed tomography showed a big femoral pseudoaneurysm. Taken again to the theater and via a contralateral puncture a viabahn covered endograft was deployed from the external iliac artery to the yet diseased but patent femoral superficial femoral artery and the pseudoaneurysm was punctured, emptied, and filled with thrombin. The patient was discharged 2 weeks after the last procedure and lived for 10 months (she died because of a nonvascular related cause) with a patent graft and with healed lesions. CONCLUSIONS: In this case the endovascular solution was a definitive solution in a very old patient with several comorbidities.

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.

BACKGROUND: In the workup of a pediatric patient with pericarditis we found evidence of a pseudo-aneurysm of the left ventricle, which is a rare complication of purulent pericarditis. CASE PRESENTATION: We present a case of a six-year-old girl who was diagnosed with pericarditis and a fistula between the pericardial and the intra-luminal space of the left ventricle of the heart. She was successfully treated with antibiotics and cardio-thoracic surgery. We found 23 published cases (21 with follow-up) of infectious pseudo-aneurysm of the heart, of which 19 underwent surgery, 5 had fatal outcome, and 2 who refused surgery survived. The majority of cases were associated with Staphylococcus aureus. The exact mechanisms of this rare complication remain unknown. CONCLUSIONS: A pseudo-aneurysm of the left ventricle is a rare and not well understood complication of a purulent pericarditis most commonly caused by Staphylococcus aureus infection. Because of risk of rupture, surgical intervention is advised.

A 67-year-old man with diabetes and hypertension presented with complaints of abdominal pain and lower back ache for 7 months, with intermittent episodes of fever. On examination, there was an expansile mass in the upper abdomen with bruit on auscultation. He also had tenderness in the L1-L2 vertebral space with paraspinal fullness, causing painful restriction of lower limb motor functions but without affecting sensation. On evaluation, he was found to have an abdominal aortic aneurysm with infective lumbar spondylodiscitis. The aspirate from the paravertebral infected tissue and cultures from blood grew Pseudomonas aeruginosa, a rare causative agent of mycotic aortic aneurysm. Whether the infective spondylitis spread to the abdominal aorta causing the mycotic aneurysm or vice versa is a dilemma in such a case. However, the mainstay of treatment remains adequate source control and repair of the aneurysm with appropriate antibiotic therapy. Our patient received intravenous antibiotics for P . aeruginosa based on sensitivity, following which he underwent debridement of the infective spondylodiscitis with aneurysmorrhaphy. He had an uneventful recovery and was well at 3-month follow-up.

BACKGROUND: Clostridium septicum is an anaerobic, motile, spore-forming, toxin-producing gram-positive bacillus that can lead to rapidly progressive gas gangrene due to the release of alpha toxin. Aortic aneurysm secondary to C. septicum infection is a rare condition with 60 cases reported in the literature; however, we have recently treated several patients with the condition in our large tertiary care and aortic center. METHODS: Blood and tissue culture results collected between January 2005 and January 2018 and maintained in the microbiology laboratory database at the Cleveland Clinic were reviewed to identify those with C. septicum reported. Each was reviewed to determine radiographic or histopathologic correlation with aortic disease. RESULTS: Seven cases of C. septicum aortitis were reviewed. Underlying malignant disease was found in four cases and a history of remote malignant disease in one case. The most common location for infection was the infrarenal abdominal aorta. Vascular surgery had previously been performed in three of the cases. Five of the seven patients underwent operative repair. All patients were treated with ß-lactam antibiotics. The two patients who did not undergo an operation died, which is consistent with the 100% mortality described in the literature. Of the five patients who underwent an operation, there was only one documented survivor and one was lost to follow-up. CONCLUSIONS: In the largest reported case series, only a small percentage of patients with C. septicum-infected aortic aneurysms survived >1 year. In the patients described, those who did not receive an operation had 100% mortality. Earlier recognition and prompt operation with appropriate antimicrobial therapy are needed to improve the outcome of patients diagnosed with this rare infection.
