La BCGitis es una complicación infrecuente del tratamiento intravesical con Bacillus Calmette-Guérin para el cáncer superficial de vejiga de alto grado y el carcinoma in situ. Puede causar afectación vascular. Presentamos 2 casos y una revisión de la literatura de series de casos publicadas en los 10 años previos a la finalización de este trabajo en abril de 2022, que describiesen un caso de aneurisma micótico aortoilíaco tras recibir este tratamiento. De los 51 casos incluidos (49 revisados y 2 originales), el 100% eran hombres, 82% tenían más de 65 años. La mediana del período de latencia fue de 15 meses (RIQ 18). La localización más frecuente fue la aorta abdominal, documentándose rotura en el 45,1%. El síntoma más frecuente fue dolor abdominal o lumbar (61%), seguido de síndrome general (49%). Asoció absceso retroperitoneal un 39,2%. La mortalidad atribuible fue de 13,6%. La BCGitis debería incluirse como diagnóstico diferencial de pacientes que hayan recibido terapia con BCG y presenten afectación vascular, incluso años tras el tratamiento.(AU)

BCGitis is a rare complication after intravesical administration of Bacillus Calmette-Guérin for high-grade superficial bladder cancer and carcinoma in situ. May cause vascular involvement. We present two cases and a review of the literature of the case reports published on the 10 years prior to April of 2022, when this project was finished, which described a case of aortoiliac mycotic aneurysm after receiving this treatment. Of the 51 cases included (49 revised and 2 original), 100% were men, 82% were older than 65 years. The median latency period was 15 months (IQR 18). The most frequent location was the abdominal aorta, rupture occurred in 45.1% of patients. The most frequent symptom was abdominal or lumbar pain (61%), followed by general syndrome (49%). In 39.2% cases, it was associated with retroperitoneal abscesses. Attributable mortality was 13.6%. BCGitis should be included in the differential diagnosis in patients who have received BCG therapy and present vascular involvement, even years after being treated.(AU)

Hoarseness Due to Aortic Arch Aneurysms.

OBJECTIVE: To give an overview of the Ortner's syndrome caused by an aortic arch aneurysm. METHODS: By comprehensive retrieval of the pertinent literature published in the past two decades, 75 reports including 86 patients were collected and recruited into this study along with a recent case of our own. RESULTS: The aortic arch aneurysms causing hoarseness were most commonly mycotic aneurysms. In this patient setting, in addition to the left recurrent laryngeal nerve, trachea was the most commonly affected structure by the aortic arch aneurysm. Surgical/interventional/hybrid treatments led to a hoarseness-relieving rate of 64.3%, much higher than that of patients receiving conservative treatment. However, hoarseness recovery took longer time in the surgically treated patients than in the interventionally treated patients. CONCLUSION: The surgical and interventional treatments offered similar hoarseness-relieving effects. Surgical or interventional treatment is warranted in such patients for both treatment of arch aneurysms and relief of hoarseness.

Successful Endovascular Treatment of an Infected Aortic Aneurysm Induced by Klebsiella pneumoniae.

Aortic aneurysms infected by Klebsiella pneumoniae are rarely seen. We describe a 50-year-old man with infected aortic aneurysm that was successfully treated with endovascular aneurysm repair (EVAR). Diagnosis was confirmed using blood culture and computed tomography (CT). Intravenous antibiotics were immediately administered, with improvements in clinical findings and negative blood cultures before the procedure. Twenty-four months after the procedure, the patient was stable and serial CT revealed regression of the infected aortic aneurysm. Therefore, after controlling bacteremia and fever with targeted antibiotic therapy, EVAR can be considered as an alternative for patients who have serious comorbidities and are ineligible for conventional surgery.

Pneumococcal urinary antigen test: A tool for pneumococcal aortitis diagnosis?

Introduction: Aortitis is rare. The etiological diagnosis is difficult but essential for treatment. Even with appropriate treatment mortality remains high. We present a case of pneumococcal aortitis followed by a brief review of the literature. Presentation of Case: In this case, the aortic disease was characterized by multiple inflammatory aneurysms. Blood cultures were negative but urine was tested for the presence of pneumococcal urinary antigen postoperatively was positive. Treatment consisted of antibacterial therapy and both surgical and endovascular procedures. The patient was discharged and is well. Discussion: Preoperative determination of etiology is crucial in implementing a specific treatment. Pneumococcus is a common bacterium in infectious aortitis. Identification of the causative microbe is necessary to guide antimicrobial therapy. Blood cultures are frequently sterile. The pneumococcal urinary antigen test may be more sensitive than blood cultures, as is the case in pneumococcal pneumonia. Conclusions: The pneumococcal urinary antigen test may was a useful diagnostic tool in establishing the cause for aortitis in this case. Its potential value should be assessed in furthers studies.

Mycotic Pulmonary Artery Aneurysm Mimicking a Rasmussen Aneurysm.

BACKGROUND: Mycotic aneurysms arising from the pulmonary arteries are rare; only a few cases have been reported. Staphylococcus and Streptococcus species are the most common causative pathogens. Mycotic aneurysms are seldom clinically apparent unless as a sequela of adverse procedural complications. They carry high morbidity and mortality if not treated expeditiously. CASE REPORT: We present the case of a 37-year-old male with bacteremia and bronchopneumonia associated with a pulmonary artery mycotic aneurysm. The case was confounded by clinical features mimicking a Rasmussen aneurysm. We discuss distinctive imaging features, disease mechanism, typical presentation, and management. CONCLUSION: While mycotic aneurysms are uncommon, certain clinical scenarios warrant consideration of the diagnosis, such as a history of intravenous drug use, bacterial endocarditis, and immunocompromise. Rapid identification is critical to prevent life-threatening complications such as vessel rupture. Computed tomography allows for an accurate and timely diagnosis, and interventional embolization is a fast, minimally invasive curative treatment. Given similar risk factors and presentation, a mycotic aneurysm can be indistinguishable from a Rasmussen aneurysm; therefore, appropriate precautions should be taken while adequate microbiologic assessment is performed.

A Case of Behçet's Disease Mimicking Vertebral Invasion of a Mycotic Aneurysm / 대한내과학회지

Behçet's disease is a systemic vasculitis of unknown etiology characterized by recurrent oral and genital ulcers and uveitis. The vascular involvement of Behçet's disease affects arteries, veins, and blood vessels of all sizes, and it can include venous or arterial thrombosis and arterial aneurysms. There are only a few reports of an aortic aneurysm invading a vertebral body in a patient with Behçet's disease. Here, we report the case of a 45-year-old man who was initially diagnosed with vertebral invasion of a mycotic aneurysm. He underwent vascular surgery and received empirical antibiotics, but all cultures were negative. However, he had persistent, recurrent deep vein thrombosis and elevated inflammatory markers. After reviewing the pathology, a final diagnosis of Behçet's disease was made. He was successfully treated with corticosteroids. This report presents a rare case of Behçet's disease mimicking vertebral invasion of a mycotic aneurysm.

Healthy Adolescent with a Mycotic Aortic Aneurysm from Community-Acquired Methicillin-Resistant Staphylococcus aureus.

Mycotic aneurysm after bacteremia is a rare diagnosis in children and adolescents. We report the case of a previously healthy adolescent who presented with chest pain and fever and who developed a mycotic aneurysm of the aorta after contracting community-acquired, methicillin-resistant Staphylococcus aureus. Early recognition of widening of the patient's superior mediastinum, noted during a comparison of the patient's initial and follow-up chest radiographs, prompted computed tomographic angiography of the chest and led to a timely diagnosis, rapid surgical intervention, and a good clinical outcome. To our knowledge, this is the first reported case of mycotic aortic aneurysm from community-acquired methicillin-resistant S. aureus in a healthy adolescent who had no predisposing cardiac or aortic anomalies.

Mycotic aneurysm with aortoduodenal fistula.

Firstly described in the 19th century by Sir William Osler, the mycotic aneurysm (MA) is a rare entity characterized by an abnormal arterial dilation, which is potentially fatal, and is associated with the infection of the vascular wall. Elderly patients are mostly involved, especially when risk factors like chronic diseases, immunosuppression, neoplasia, and arterial manipulation are associated. The authors report the case of a young male patient diagnosed with an aortic aneurysm of infectious origin in the presence of repeated negative blood cultures. The diagnostic hypothesis was raised when the patient was hospitalized for an inguinal hernia surgery. The diagnosis was confirmed based on imaging findings consistent with mycotic aneurism. The patient was treated with an endovascular prosthesis associated with a long-lasting antibiotic therapy. Five months later, the patient attended the emergency unit presenting an upper digestive hemorrhage and shock, from which he died. The autopsy revealed a huge aneurysm of the abdominal aorta with an aortoduodenal fistula. The histological examination of the arterial wall revealed a marked inflammatory process, extensive destruction of the arterial wall, and the presence of Gram-positive bacteria. This case highlights the atypical presentation of a MA associated with an aortoduodenal fistula. Besides the early age of the patient, no primary arterial disease could be found, and no source of infection was detected.

Infectious Pseudoaneurysm Caused by Group A Streptococcus in a Child without Underlying Disease

Group A streptococcus is a common cause of upper respiratory infection in children; however, it is a rare cause of pseudoaneurysm in pediatrics with only limited reports of cases associated with cardiac surgery and underlying disease. We report a case of infectious pseudoaneurysm of the right internal iliac artery caused by group A streptococcus in a previously healthy 5-year-old boy who presented with scarlet fever and group A streptococcal bacteremia. He was admitted to the hospital with fever, rash on the whole body, and sore throat, accompanied by severe leg pain. He was treated with surgical removal and antibiotics. Because a pseudoaneurysm may develop in children without vascularrelated underlying diseases, we should consider the possibility of this important clinical diagnosis in patients with scarlet fever.

Nationwide Study of the Treatment of Mycotic Abdominal Aortic Aneurysms Comparing Open and Endovascular Repair.

BACKGROUND: No reliable comparative data exist between open repair (OR) and endovascular aneurysm repair (EVAR) for mycotic abdominal aortic aneurysms (MAAAs). This nationwide study assessed outcomes after OR and EVAR for MAAA in a population-based cohort. METHODS: All patients treated for MAAAs in Sweden between 1994 and 2014 were identified in the Swedish vascular registry. The primary aim was to assess survival after MAAA with OR and EVAR. Secondary aims were analyses of the rate of recurrent infections and reoperations, and time trends in surgical treatment. Survival was analyzed using Kaplan-Meier and log-rank tests. A propensity score-weighted correction for risk factor differences in the 2 groups was performed, including the operation year to account for differences in treatment and outcomes over time. RESULTS: We identified 132 patients (0.6% of all operated abdominal aortic aneurysms in Sweden). Mean age was 70 years (standard deviation, 9.2), and 50 presented with rupture. Survival at 3 months was 86% (95% confidence interval, 80%-92%), at 1 year 79% (72%-86%), and at 5 years 59% (50%-68%). The preferred operative technique shifted from OR to EVAR after 2001 (proportion EVAR 1994-2000 0%, 2001-2007 58%, 2008-2014 60%). Open repair was performed in 62 patients (47%): aortic resection and extra-anatomic bypass (n=7), in situ reconstruction (n=50), and patch plasty (n=3); 2 patients died intraoperatively. EVAR was performed in 70 patients (53%): standard EVAR (n=55), fenestrated/branched EVAR (n=8), and visceral deviation with stent grafting (n=7); no deaths occurred intraoperatively. Survival at 3 months was lower for OR than for EVAR (74% versus 96%, P<0.001), with a similar trend present at 1 year (73% versus 84%, P=0.054). A propensity score-weighted risk-adjusted analysis confirmed the early better survival associated with EVAR. During median follow-up of 36 and 41 months for OR and EVAR, respectively, there was no difference in long-term survival (5 years 60% versus 58%, P=0.771), infection-related complications (18% versus 24%, P=0.439), or reoperation (21% versus 24%, P=0.650). CONCLUSION: This study demonstrates a paradigm shift in treatment of MAAA in Sweden, with EVAR being the preferred treatment modality. EVAR was associated with improved short-term survival in comparison with OR, without higher associated incidence of serious infection-related complications or reoperations.

Infective Endocarditis of the Aortic Valve with Anterior Mitral Valve Leaflet Aneurysm.

Mitral valve leaflet aneurysm is a rare and potentially devastating complication of aortic valve endocarditis. We report the case of a 48-year-old man who had endocarditis of the native aortic valve and a concomitant aneurysm of the anterior mitral valve leaflet. Severe mitral regurgitation occurred after the aneurysm perforated. The patient showed no signs of heart failure and completed a 6-week regimen of antibiotic therapy before undergoing successful aortic and mitral valve replacement. In addition to the patient's case, we review the relevant medical literature.

Management of a Mycotic Thoracoabdominal Aortic Aneurysm Involving the Celiac Artery.

A mycotic aneurysm that also involves the visceral arteries is a life-threatening condition. Surgical management typically consists of débridement and in situ repair with a Dacron graft and reimplantation of the involved visceral branches. We report a rare case of a mycotic saccular thoracoabdominal aortic aneurysm involving the celiac artery, with Streptococcus pneumoniae as the responsible organism. Successful repair of the aneurysm and concomitant revascularization of the celiac artery were achieved.

Clinical analysis of infective endocarditis complicated with intracranial hemorrhage / 中华全科医师杂志

Objective To analyze the clinical characteristics of infective endoearditis complicated with intracranial hemorrhage.Methods The clinical characteristics,brain CT and MRI results and prognosis of 7 patients with infective endocarditis and intracranial hemorrhage admitted between January 1991 and May 2015 were retrospectively analyzed.Results All seven patients presented varying degrees of fever,cardiac murmur and neurological symptoms.The continuous fever lasted from 21 d to 227 d (average 91 d).Mitral valve (4 cases) and aortic valve (3 cases) were the most common affected ones.The brain CT or MRI scan presented intracranial hemorrhage in 6 cases.More than 2 hemorrhage locations were found in 5 patients and parietal lobe was most common one (4 cases).All patients were treated with antimicrobial agents and three patients underwent valve replacement surgery.Three patients were cured and another 2 died due to fatal hemorrhage.Conclusions Patients with long fever history and ineffective antimicrobial treatment are prone to intracranial hemorrhage.Brain CT or MRI scan need be performed in infective endocardits when neurological symptoms are present,and brain angiography should be also considered if necessary.
