Tuberculous aortitis with jejunal artery mycotic pseudoaneurysm managed by endovascular coil embolisation.

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.

Impending Aortic Rupture in a Patient with Syphilitic Aortitis.

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.

Favorable Conservative Management of a Rare Primary Aortitis Secondary to Listeria Monocytogenes: Case Report and Review of the Literature.

Primary aortitis (PA) secondary to Listeria monocytogenes is extremely rare with only a few cases reported in the literature. Presently, there is no consensus concerning the best treatment when no complications are found in the thoracic computed tomography (CT) imaging. This report illustrates the clinical presentation and favorable clinical course of a rare case of PA secondary to Listeria monocytogenes in an 82-year-old diabetic woman, successfully treated with conservative management with 18 months of follow up. Included in this article, we additionally present a review of the literature of this uncommon etiology of infectious aortitis.

Gas Where It Shouldn't Be! Imaging Spectrum of Emphysematous Infections in the Abdomen and Pelvis.

OBJECTIVE. The purpose of this article is to review the spectrum, etiopathogenesis, clinical presentation, imaging features, differential diagnoses, and management of emphysematous infections of the abdomen and pelvis. CONCLUSION. Emphysematous infections are associated with high morbidity and mortality and thus need urgent medical and surgical interventions. CT is the most sensitive modality to detect gas; CT provides definitive diagnosis in most cases and can depict the extent of involvement.

A strobe multicenter descriptive study of 55 infectious aortitis.

Infectious aortitis (IA) is a rare and severe disease. The treatment classically associates open surgery with prolonged antibiotic therapy. This study aimed to describe clinical characteristics, medical and surgical supports in a large and current series of IA.We conducted a retrospective multicenter study of native aorta IA, between 2000 and 2019. Inclusion criteria were the presence of a microorganism on blood culture, aortic sample or any other validated technique and structural anomaly in imaging.We included 55 patients (85% men), with a median age of 65. Microbiology data substantially differed from previous studies with 12 Gram-negative rods IA, of which only 3 due to Salmonella spp., 24 Gram-positive cocci IA of which 12 Streptococcus spp., and 18 IA due to intracellular growth and/or fastidious microorganisms, of which 8 Coxiella burnetii, 3 Treponema pallidum, and 5 tuberculosis suspicious cases. Fifteen patients (27%) presented with thoracic IA, 31 (56%) with abdominal IA, and 9 (16%) with thoraco-abdominal IA. Eight patients had no surgery, 41 underwent open surgery, only 4 endovascular aneurysm repair, and 2 a combination of these 2 techniques. Nine patients died before 1-month follow-up. There was no difference in the mortality rate between the different types of germ or localization of IA.The variety of germs involved in IA increases. Positron emission tomography-computed tomography scan is a very useful tool for diagnosis. Surgery is still mainly done in open approach and a prospective multicenter study seems necessary to better determine the place of endovascular aneurysm repair versus open surgery.

Syphilitic aortitis: still a current common cause of aneurysm of the tubular portion of ascending aorta.

Aortic syphilis today is infrequently diagnosed clinically. Described herein are findings in 5 women who had resection of a fusiform aneurysm of the tubular portion of ascending aorta, and examination of the wall of the aneurysm disclosed classic features of aortic syphilis. The 5 patients were among 36 who had ascending aortic operations at Baylor University Medical Center in Dallas in 2018 and early 2019. Syphilitic aneurysm in each spared the sinus portion and involved diffusely the tubular portion of ascending aorta, beginning at the sinotubular junction. The aneurysmal wall was thicker than normal because of thickening of both intima and adventitia. The latter contained foci of lymphocytes and plasmacytes and thickened and narrowed vasa vasora. The media was disrupted by fibrous scars, which weakened the integrity of the aorta. Aortitis of the tubular portion of ascending aorta in syphilis is a diffuse process, but often is mistakenly called "atherosclerosis" which, when present in this portion of aorta, can be extensive but is focal. Aortic syphilis is important to diagnose so that patients can receive antibiotic therapy to delay, prevent, or treat neurosyphilis, a common accompaniment of aortic syphilis.

Clostridium septicum aortitis: A kiss of the devil.

BACKGROUND: Clostridium septicum aortitis is a lethal infection. C. septicum has a strong association with an underlying malignancy, most commonly in the colon. AIM: Early identification methods and management strategies of C. Septicum infection. MATERIALS AND METHODS: We present a 64-year-old man with aortic aneurysm and C. septicum bacteremia with unknown malignancy who passed away on the fourth day of hospitalization despite emergent endovascular intervention. Computed tomography showed periaortic gas which is the hallmark of infection. DISCUSSION: This case report highlights the need of prompt surgical treatment and its different modalities along with the early use of appropriate antibiotics due to the rapid spread of infection associated with high fatality. The authors also discuss the association of C. septicum aortitis with underlying occult malignancies. CONCLUSION: Delay in identification and treatment of C. Septicum is associated with very high mortality rates.

[Salmonella aortitis in an elderly patient†: clinical case and review of the literature]. / Aortite à salmonelle chez un patient âgé†: cas clinique et revue de la littérature.

Gastroenteritis due to non-typhoidal Salmonella (NTS) is usually considered as a benign infection. NTS can nevertheless cause severe diseases with high mortality. Invasive NTS infections may present as bacteremia without other manifestations, particularly in immunocompromised hosts. They may also correspond to extra-digestive infections in various body sites. Patients with cardiovascular diseases are at risk for endovascular infections, aortitis being the most frequent. These infections are difficult to diagnose and require surgery.

La gastroentérite à salmonelle non typhoïde est une maladie généralement considérée comme inoffensive. Pourtant, chez certains hôtes, cette bactérie peut se montrer particulièrement virulente et mener à des complications avec une mortalité élevée. Nous décrivons un cas d'aortite à Salmonella enteritidis chez un patient âgé avec un profil athérosclérotique. La salmonellose invasive peut prendre la forme d'une bactériémie isolée, surtout chez les patients immunosupprimés. Dans d'autres cas, elle se manifeste par des foyers extradigestifs de localisations diverses. Les infections endovasculaires, dont l'aortite est la plus fréquente, atteignent les patients à haut risque cardiovasculaire ; elles sont difficiles à diagnostiquer et nécessitent une prise en charge médico-chirurgicale.

Bartonella Quintana prosthetic aortitis successfully treated with doxycycline.

Bartonella quintana is a rare cause of culture-negative endovascular infection, characterised by intracellular persistence. We describe a case of ascending aortic prosthetic graft infection due to B. quintana, in a patient with past unrecognised necrotising aortitis, which was successfully treated with doxycycline monotherapy.

Successful Treatment of an Aortotomy Site Aspergillus Infection.

Aspergillus aortitis is a rare, often fatal infection. Here, we report successful treatment of an aortotomy site that became infected by Aspergillus spp. after valve replacement. Surgical debridement, combined with antifungal therapy, allowed a favorable outcome.

A case of Brucella aortitis associated with development of thoracic aortic aneurysm and aortobronchial fistula.

OBJECTIVES: The purpose of this case report is to document the occurrence of granulomatous aortitis complicated by formation of a saccular aneurysm and aortobronchial fistula due to Brucella infection. METHODS: A 65-year-old man with a history of feral swine hunting presented with hemoptysis and was found to have a saccular thoracic aortic aneurysm and associated aortobronchial fistula. The aneurysm underwent operative repair with closure of the aortobronchial fistula. RESULTS: Histopathological examination of the aneurysm wall revealed evidence of granulomatous aortitis. Cultures of the blood and aortic wall tissue were positive for Brucella suis. CONCLUSIONS: Although rare, Brucella infection should be considered in the differential diagnosis of aortic aneurysm with granulomatous aortitis.

Conservative treatment of non-aneurysmal infectious aortitis: a case report and review of the literature.

BACKGROUND:  Non-aneurysmal infectious aortitis is a rare clinical entity with most often lethal complications when surgical intervention is delayed. OBJECTIVES:  This report describes the case of a non-aneurysmal infectious aortitis complicated with a penetrating aortic ulcer in an elderly woman, caused by a methicillin-sensitive Staphylococcus aureus. Surgery was deemed contra-indicated and treatment was limited to the administration of intravenous vancomycin (2 grams daily), followed by flucloxacillin (6 times 2 grams daily). She remains well after one year. METHODS: The Internet databases Medline and Embase were searched. Articles were selected based on relevanceof abstract, article type and impact of the journal. RESULTS:  A literature review addresses current insights in the pathogenesis, diagnosis, and treatment of non-aneurysmal infectious aortitis.

Acute infectious aortitis presenting as pyelonephritis.

A 65-years-old man with poorly controlled type 2 diabetes presented to the emergency department in sepsis with a 2-week history of new-onset fever, abdominal pain and pyuria. A Computed Tomography without contrast ruled out nephrolithiasis and hydronephrosis, but showed infiltration around the infra-renal aorta (5 x 1 cm) and several retroperitoneal lymph nodes. The periaortic infiltration raised suspicion for acute infectious aortitis. Aortic CT angiography confirmed an aortic pseudo-aneurysm in the infra-renal aorta without signs of impending aortic rupture. A Positron Emission Tomography-Computed Tomography confirmed abnormal 18F-FDG uptake adjacent to the right posterolateral aortic wall. The patient underwent abdominal aortic reconstruction with cryopreserved arterial allograft. Infectious aortitis is a rare but lethal cause of sepsis. Males over 50 years old with diabetes mellitus and peripheral vascular atherosclerotic disease are considered at higher risk. The diagnosis should be considered when a septic patient has vascular risk factors, abdominal pain, bacteremia and suggestive imaging. A CT without contrast showing infiltration around the aorta should, in some context, be promptly followed by Aortic CTA to search for acute aortitis among other less urgent differentials. Antibiotic therapy and involvement of vascular surgeons should be initiated in the emergency department.

Transient aortitis documented by positron emission tomography in a case series of men and transgender women infected with syphilis.

OBJECTIVES: Syphilis infection persists globally contributing to preventable and treatable morbidity and mortality. How extensive early syphilis disseminates is unknown. To better understand the relationship between early syphilis infection and inflammation over time, our study enrolled six individuals recently infected with syphilis for sequential positron emission tomography (PET) scans. METHODS: We evaluated a case series of six individuals with high syphilis titres (two secondary, two early latent and two latent, unknown duration, but with high titre) who received sequential PET scans to assess inflammation over time and its response to treatment. RESULTS: At time of PET scan, four of the six individuals were co-infected with HIV. One of the four was not on antiretroviral therapy and three of the four were not virally suppressed (viral load of >400 copies/mL). Baseline rapid plasma reagin (RPR) titres ranged from 1:64 to 1:256 (four of the six participants had prior non-reactive RPR results). Five of the six participants had mild to intense hypermetabolic PET scan activity consistent with cervical (n=5), axillary (n=4), inguinal (n=5) and retroperitoneal (n=1) adenopathy. Mild hypermetabolic activity in the thoracic aortic wall, suggesting aortitis, was present among the same five participants and resolved within 30 days for four of the five participants and 60 days for the other participant. However, widespread lymphadenopathy remained present in PET scans up to 3 months following treatment in two participants. We did not find any abnormal PET scan activity of the central nervous system. CONCLUSION: We found abnormal aortic wall PET scan activity suggesting aortitis to be common in a case series of patients with early syphilis. In research settings, PET scans may be a sensitive tool to monitor inflammation associated with syphilis.

Endovascular Repair as a Bridge to Open Repair of a Ruptured Descending Thoracic Aspergillus Aortitis.

Invasive aspergillosis rarely involves the thoracic aorta and is associated with a poor prognosis. A 56-year-old heart transplant recipient presented with invasive aspergillosis, primary Aspergillus aortitis, and a ruptured thoracic aorta pseudoaneurysm. Open surgical repair was not possible because of severe sepsis. Therefore, a sequential surgical strategy was planned, including emergency thoracic endovascular aortic repair, followed by antifungal treatment and definitive open repair with explantation of the endograft and placement of a cryopreserved arterial allograft under extracorporeal membrane oxygenator support. The infection did not reoccur during follow-up, and the patient remained alive and well 13 months after the operation.
