[Surgical treatment of a patient with syphilitic aortitis]. / Khirurgicheskoe lechenie patsienta s sifiliticheskim aortitom.

Syphilitic aortitis is a rare disease caused by Treponema pallidum affecting the aorta and leading to inflammation. Syphilitic aortitis is one of the causes of aortic aneurysms. This article presents surgical treatment of a patient with syphilitic aortitis and thoracic aortic aneurysm. This clinical case confirms the difficulties of surgical treatment.

Successful surgical treatment of Stanford type A aortic dissection due to Salmonella aortitis.

BACKGROUND: Salmonella spp. cause infectious aortitis through the hematogenous spread of an intestinal Salmonella infection. Salmonella aortitis can result in extensive tissue damage in the aorta leading to complications including dissection, abscess formation, pseudoaneurysms, and rupture, which require early diagnosis and treatment with both surgery and antibiotic therapy. CASE PRESENTATION: We report a case of Salmonella aortitis complicated by Stanford type A aortic dissection. A 62-year-old man with a history of heroin use presented with chest pain, epigastric pain and vomiting. The computed tomography scan showed Stanford type A aortic dissection without malperfusion. At the time of surgery, an aortic dissection with purulent fluid and contained rupture was noted in the ascending aorta. Fluid culture was consistent with Salmonella. A composite valve-graft conduit aortic root replacement with ascending aorta and hemiarch replacement was performed. The patient recovered well and was discharged on long-term antibiotics. CONCLUSIONS: This rare case of a Stanford type A aortic dissection with contained rupture due to Salmonella aortitis was successfully treated with emergent surgery and antibiotic therapy.

Management of Inflammatory Aortic Aneurysms - A Scoping Review.

OBJECTIVE: Inflammatory abdominal aortic aneurysms (InflAAAs) account for 5 - 10% of aortic aneurysms and are characterised by retroperitoneal fibrosis. Diagnosis is often delayed, and doubts remain about the optimal management strategy. This scoping review describes the current state of knowledge on InflAAAs. METHODS: Medline, PubMed, EMBASE, and Scopus were searched for relevant studies that evaluated the diagnosis and treatment of InflAAAs. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol was followed. RESULTS: Fifty-seven papers were selected (low level of evidence), which included 1 554 patients, who were mostly male and heavy smokers. A triad of chronic abdominal or back pain, weight loss, and elevated inflammatory markers was highly suggestive of the diagnosis but rarely present, and fever was noted only randomly. A mantle sign was seen on computed tomography angiography (CTA) in 73 - 100% of patients. Open surgical repair (OSR) and endovascular aortic aneurysm repair (EVAR) was reported in 1 376 and 178 patients, respectively. OSR was associated with significant iatrogenic bowel (n = 22), urinary tract system (n = 7), venous (n = 30), pancreatic (n = 6), and splenic (n = 5) injuries, while EVAR was associated with lower 30 day mortality (0 - 5% vs. 0 - 32%). One and two year mortality rates were similar between the two treatment modalities (0 - 20% and 0 - 36%, respectively). EVAR was more often associated with post-operative progression of inflammation (17% vs. 0.4%), and a higher frequency of persistent hydronephrosis (> 50%) and limb occlusion (20%). Used in < 10% of patients, corticosteroids led to complete pain relief and a reduction in peri-aortic inflammation within 6 - 18 months. CONCLUSION: InflAAAs are characterised by non-specific symptoms, with the mantle sign on CTA being pathognomonic. Corticosteroids may be considered a basic treatment that all patients should receive initially. Low quality data indicate that EVAR (vs. OSR) is associated with fewer intra-operative complications and lower peri-operative mortality but more late fibrosis related adverse events. International multicentre registries are required to gather more insights into this challenging pathology.

Brucella aortitis managed with debridement, extra-anatomical bypass, and long-term antimicrobial therapy.

OBJECTIVES: This report aims to review the management and outcomes of Brucella-associated mycotic aortic aneurysms. METHODS: This is a retrospective chart review at a tertiary-level healthcare system. IRB approval was waived per policy. RESULTS: We describe a case of Brucella aortitis acquired from habitual contact with wild hogs. Clinical presentation included lower back pain and elevated white blood cell count. Diagnosis was confirmed with imaging showing an infrarenal abdominal aortic aneurysm and serology revealing elevated Brucella antibodies titers. The patient was initially managed with endovascular aortic repair and combined oral and intravenous antibiotics therapy. He then underwent explanation and extra-anatomical bypass due to symptomatic periaortic infection and interval development of type I endoleak. The patient was asymptomatic after his final operation at 24 months of follow-up and remained on suppressive oral antibiotic therapy. CONCLUSIONS: An aortic aneurysm secondary to Brucella is a rare entity. A detailed history of long-term exposure to animals may be a clue to obtain serologic testing. Operative debridement and re-establishing of reliable blood flow combined with long-term antibiotic suppression are the mainstay of treatment.

Endovascular salvage of tubercular aortitis presenting as descending thoracic aortic pseudoaneurysm in association with vertebral tuberculosis.

A gentleman in his late 30s presented with a history of evening rise of temperature and generalised malaise of 1-week duration. He had associated upper back pain with tingling and numbness of both lower limbs. An unexplained episode of hypotension with hemoptysis propelled a computed tomography (CT) examination of chest which was suggestive of a pseudoaneurysm of the posterior wall of descending thoracic aorta in the vicinity of the Pott's spine with a prevertebral and paravertebral abscess, for which he was referred to vascular surgeons.Tubercular involvement of vasculature is a rare disease, aortic involvement even rarer. Less than 50 cases of vertebral tuberculosis with tubercular thoracic aortic aneurysm have been reported in the medical literature, but the disease carries a colossal mortality and morbidity.After a multidisciplinary teamwork, thoracic endovascular aortic repair was done for exclusion of the aneurysmal segment, with simultaneous antitubercular and broad-spectrum antibiotic chemotherapy. The patient recuperated well.

Systematic literature review and meta-analysis of Clostridium septicum aortitis.

BACKGROUND: Clostridium septicum bacteremia is often associated with occult malignancies (approximately 80%), especially of the right colon. Furthermore, inflammation of the aortic wall can rapidly lead to aneurysm induction through bacterial seeding into atheromatous lesions with consecutive life-threatening rupture. We summarize all published data on this rare and lethal disease to evaluate therapeutic approaches and give valid treatment recommendations because there are no guidelines. METHODS: A systematic review of the literature was conducted screening EMBASE and MEDLINE databases following the PRISMA guidelines with search period from first description to August 25, 2021. RESULTS: There were 72 cases of C septicum aortitis reported in 64 publications. Endovascular aortic repair (EVAR) was performed in a minority of patients (n = 6) unfit for surgery but lacked long-term survivors. Antibiotic treatment was beneficial in a bridge to surgery concept, but up to now harbored a 6-month mortality rate of 100% (median overall survival, 0.5 months) when no additional aortic repair was performed. Open aortic repair was the only potential curative approach but was accompanied with a 90-day-mortality of 26.7% (4/15). CONCLUSIONS: Open aortic repair combined with perioperative antibiotic treatment should be offered to all patients as the only potentially curative approach. If applicable, resection of a coexisting colonic tumor should be performed after successful aortic repair. Alternatively, long-term antibiotic treatment can be offered to patients unfit for surgery in a palliative setting. Endovascular aortic repair has been performed on a minority of patients with a high risk for stent graft infection and should remain a salvage strategy when therapeutic pressure demands acute intervention in patients unfit for surgery.

The Femoral Vein as a Long-Term Aorto-Iliac Graft for Aortic Infection and Aortitis.

BACKGROUND: Reconstruction of the aorto-iliac segment with femoral vein (FV) as substitute for infected synthetic grafts or mycotic aneurysms constitutes the most sustainably convenient alternative. The aim of this study was to evaluate the long-term outcome of up to 16 years of follow-up, analysing the morphologic adaption of the FV with special emphasis on the distal and proximal anastomoses. METHODS: We conducted a retrospective study of 22 patients with 109 computed tomography angiograms (CTAs) treated between August 2001 and January 2020 in case of aortic infection/aortitis. Morphologic changes like anastomotic dilatation/stenosis as well as changes of FV wall thickness were retrospectively analysed in pre- and postoperative CTAs. RESULTS: Elective procedure was done in 17/22 (77%) cases, and 5/22 (23%) patients required emergent surgery. The median follow-up was 91.5 months (P25;P75 = 21;117). Cross-sectional diameter of proximal (20.38 ± 3.77 vs 22.04 ± 3.97 mm, p = 0.007) and distal anastomoses (13.05 ± 4.23 vs 14.61 ± 5.19 mm, p = 0.05) increased significantly, as well as the proximal and distal anastomotic areas (3.36 ± 1.29 vs 4.32 ± 1.63 mm2, p = 0.04 and 0.99 ± 0.48 vs 1.25 ± 0.72 mm2, p = 0.023, respectively). Venous wall thickness was significantly reduced at the anastomotic site (1.74 ± 0.46 vs 1.24 ± 0.31 mm, p = 0.001). The upper thigh diameter did not differ before and after harvesting of the FV (161.6 ± 29.1 vs. 178.2 ± 23.3 mm, p = 0.326, respectively). CONCLUSION: This long-term CTA follow-up study showed that the FV wall becomes thinner at the anastomotic site, and the anastomoses dilate with time without rupture. The FV is a durable conductor after replacement of the aorto-iliac segment due to aortic infection. Further CTA studies from more centres are warranted to evaluate the risk of vein rupture.

Post-operative outcomes of inflammatory thoracic aortitis: a study of 41 patients from a cohort of 1119 surgical cases.

Aortitis is found in 2-12% of thoracic aortic aneurysm repair/replacement surgeries. Yet little is known about such patients' post-operative outcomes or the role of post-operative corticosteroids. The study was undertaken across three tertiary referral hospitals in Sydney, Australia. Prospectively collected data for all thoracic aortic repair/replacement patients between 2004 and 2018 was accessed from a national surgical registry and analysed. Histopathology records identified cases of inflammatory aortitis which were subclassified as clinically isolated aortitis (CIA), giant cell arteritis (GCA), Takayasu (TAK) or other aortitis. Between-group outcomes were compared utilising logistic and median regression analyses. Between 2004 and 2018, a total of 1119 thoracic aortic surgeries were performed of which 41 (3.7%) were inflammatory aortitis cases (66% CIA, 27% GCA, 5% TAK, 2% other). Eight out of 41 (20%) aortitis patients received post-operative corticosteroids. Compared to non-aortitis patients, the aortitis group was predominantly female (53.7% vs. 28.1%, p < 0.01), was older (mean 70 vs. 62 years, p < 0.01) and had higher prevalence of hypertension (82.9% vs. 67.1%, p = 0.03) and pre-operative immunosuppression (9.8% vs. 1.4%, p < 0.01). There was no difference (p > 0.05) between aortitis and non-aortitis groups for 30-day mortality (7.3% vs 6.5%), significant morbidity (14.6% vs. 22.4%), or infection (9.8% vs. 6.4%). Outcomes were similar for the non-corticosteroid-treated aortitis subgroup. Histologic evidence of inflammatory thoracic aortitis following surgery did not affect post-operative mortality or morbidity. Withholding corticosteroids did not adversely affect patient outcomes. These findings will assist rheumatologists and surgeons in the post-operative management of aortitis.

Infective aortitis after self-expanding transcatheter valve implantation: a case report of a new reality for cardiac surgeons.

A 62-year-old female patient was admitted to hospital care due to an ischaemic stroke and fever of unknown origin, 6 months after a transfemoral aortic valve implantation for symptomatic aortic stenosis. Further study resulted in the diagnosis of infective aortitis, and clinical course deemed prosthesis explantation necessary. In this case report, we describe the technique used to explant the partially endothelized aortic valve and review the alternatives found in literature for safe prosthesis removal.

Tuberculous aortitis in an human immunodeficiency virus-positive Ivorian migrant: A case report.

We report an unusual case of a 35-year-old Ivorian migrant with an abdominal mass and medical history relevant for human immunodeficiency virus-2 positivity with a CD4/CD8 ratio of 0.63; Mantoux and lymphocyte stimulation tests (QuantiFERON) were positive. 3D-CT images revealed a voluminous non-homogeneous retroperitoneal mass in the right abdominal region presenting no significant contrast impregnation. Thoraco-abdominal aorta presented diffuse-altered morphology with multiple ectasias throughout its course and an aneurysm at the level of the subrenal tract. The patient underwent vascular surgery. Mycobacterium tuberculosis complex was detected by polymerase chain reaction performed on intraoperative tissue specimens. Postoperative course was uneventful. After surgery, 3D-CT images showed no signs of malfunction of the prosthesis. At last, at 6-month follow-up, the patient was well. Cross-sectional imaging techniques, such as contrasted-CT, are essential and allow for making diagnosis, assessing disease activity, and evaluating post-treatment condition. 3D reconstruction permits an appropriate patient care by means of an excellent visualization and staging of the disease process.

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.

Aortitis masquerading as intramural hematoma: When to observe, when to operate? A case report.

Radiologic evidence of aortic disease is not always consistent with the diagnosis. With a lack of accompanying symptoms or with an atypical presentation, diagnosis, and management of aortic pathology rely greatly on imaging techniques. We report the case of a 58-year-old female who presented with incidental radiographic findings consistent with a type A aortic intramural hematoma and a vague left-sided chest discomfort. After follow-up, imaging was consistent with disease progression and hematoma expansion; the affected segment was resected and pathology reported lymphoplasmacytic aortitis as the underlying etiology of the imaging findings rather than an intramural hematoma. The patient lacked symptoms or serology consistent with the rheumatologic disease, and the postoperative course was uneventful. The management of a suspected ascending intramural hematoma is controversial, especially when the patient presents with atypical signs and symptoms. Features of disease progression may warrant urgent surgical intervention.

Transcatheter aortic valve implantation for severe pure aortic regurgitation due to active aortitis.

Aortitis is an uncommon systemic inflammatory disease affecting the aorta and its main branches. Severe aortic regurgitation (AR) represents a fearsome complication of aortitis and is associated with an increased mortality rate. Surgical aortic valve replacement represents the only treatment choice for these patients. However, it is associated with a higher risk of medium to long-term complications such as prosthetic valve detachment. This is the first reported case where severe AR secondary to aortitis was managed with transcatheter aortic valve implantation (TAVI). TAVI was safe and effective in this clinical setting and may be considered a viable alternative to high-risk surgery in these complex patients.

Syphilitic aortitis: chronic left coronary ostial occlusion and aortic regurgitation with aortitis.

Before the discovery of penicillin, tertiary syphilis was the most common cause of thoracic aneurysms, but now cardiovascular syphilis is a clinical rarity in developed countries. We report a case of 69-year-old man who presented with sudden onset breathlessness that worsened insidiously for 2 months. Diagnosis of syphilitic aortitis was confirmed by laboratory findings, contrast computed tomography, echocardiography and coronary angiography. The patient underwent successful coronary artery bypass graft, aortic valve replacement and ascending aortic replacement. A high level of suspicion and awareness is needed for the diagnosis of the now rare disease.

Etiology, Diagnosis and Management of Aortitis.

Aortitis includes conditions with infectious or non-infectious etiology, characterized by inflammatory changes in one or more layers in aortic wall. Age at onset, geographic predilections, distribution and pattern of involvement in aorta, its branches and pulmonary arteries, and systemic associations provide a clue to etiology. Clinical presentations are often non-specific. An integrated approach including clinical, laboratory and imaging assessment is essential to confirm diagnosis and plan treatment. Assessment of disease activity is the key as it influences timing and outcome of treatment. Markers of activity include clinical, laboratory and imaging. Medical management remains the first-line therapy. Revascularization is indicated in the presence of hemodynamically significant stenosis and inactive disease. In the presence of flash pulmonary edema, left ventricular dysfunction or hypertensive encephalopathy, revascularization is performed irrespective of disease activity. Endovascular management is favored over surgery due to its high success and low restenosis rates. Symptomatic aneurysmal disease is usually managed by 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.

Lyme aortitis.

A 72-year-old man was admitted with complaints of sudden-onset oppressive precordial pain radiating to the back for 1 hour. He had hypotension, peripheral cyanosis and cold extremities. An initial assessment was done and acute coronary syndrome was excluded. After the patient was admitted, he developed fever and increased levels of inflammatory markers. Data obtained from CT angiography and transoesophageal echocardiogram revealed diffuse parietal thickening of the arch and the descending thoracic aorta, as well as dilatation of the aortic root and the proximal ascending aorta. In addition, the test for Borrelia burgdorferi was positive, and the patient was diagnosed with Lyme vasculitis of the thoracic aorta. He was treated with doxycycline for 3 weeks. Two months later, the patient exhibited a Stanford type A aortic dissection (clinically stable), which was treated by prosthesis replacement. The patient has remained asymptomatic for 1 year after the episode, performing his routine daily activities.
