A 10-year Retrospective Comparison of Endovascular and Open Aneurysm Repair for Infective Native Abdominal Aortic Aneurysm

BackgroundThis study compared outcomes of endovascular aneurysm repair (EVAR) and open aneurysm repair (OAR) in patients with infective native abdominal aortic aneurysms (INAAA), evaluating perioperative and in-hospital mortality, antibiotic treatment duration, complications, overall survival rates, and reintervention-free times at 10 years. MethodsA retrospective cohort study of 125 INAAA patients (80 EVAR, 45 OAR) diagnosed between January 2004 and December 2019 was conducted. Patients were categorized as fit or unfit for open surgery based on cardiac, respiratory, and renal status, following the guidelines established in the EVAR-1 and EVAR-2 trials. Primary outcomes included 30-day and in-hospital mortality. Secondary outcomes encompassed early and late complications requiring reintervention, antibiotic treatment duration, 10-year overall survival, 10-year reintervention-free survival, and factors influencing 30-day mortality. Statistical analysis used chi-square, t-tests, and Mann-Whitney U tests. Logistic regression assessed mortality. Kaplan-Meier estimation evaluated survival. Analyses used SPSS version 18.0 (p < 0.05 considered significant) ResultsMales predominated in both OAR (37/45, 82.2%) and EVAR (62/80, 77.5%) groups (P = 0.693). Mean age was 64.8 ± 9.8 years for OAR and 69.0 ± 12.6 years for EVAR (P = 0.063). The abdominal aorta was the most common aneurysm location, accounting for 91/125 (72.8%) cases. Salmonella spp. accounted for 19/45 (42.2%) of positive culture cases, and 34/125 (27.2%) patients had ruptured aneurysms. The EVAR group had a higher proportion of unfit patients (41/80, 51.2%) compared to OAR (10/45,22.2%; P=0.003). 30-day mortality rates were 6/80 (7.5%) for EVAR and 2/45 (4.4%) for OAR; OR = 1.75 (95% CI: 0.34 - 9.06), P = 0.508, while in-hospital mortality rates were 7/80 (8.8%) and 5/45 (11.1%); OR = 0.77 (95% CI: 0.23 - 2.58), P = 0.668. No significant differences were found in antibiotic treatment duration (median 11 vs 6 months, P=0.594), 10-year overall survival rates (62.8% vs 64.8%, P=0.90), or reintervention-free time (83.8% vs 82.2%, P=0.922), and aneurysm-related death (84.7% vs 92.9%, P=0.159), Unfit patient status was an independent predictor of 30-day mortality (adjusted OR, 10.654; 95% CI, 1.041-109.030; P=0.046). ConclusionsOur study demonstrates that EVAR and OAR provide comparable outcomes in INAAA management, despite EVAR being performed more frequently in unfit patients. The similar early mortality rates, antibiotic treatment durations, and long-term survival between the two approaches support EVAR as a viable alternative to OAR. Importantly, our finding that unfit patient status independently predicts perioperative mortality emphasizes the critical role of patient selection in treatment decisions. These results collectively suggest that EVAR may be particularly beneficial for high-risk INAAA patients unsuitable for OAR, potentially expanding treatment options for this challenging condition.

Rapid Development and Rupture of an Infected Intracranial Aneurysm Caused by Streptococcus salivarius Meningitis: A Case Report

Rapid Development and Rupture of an Infected Intracranial Aneurysm Caused by Streptococcus salivarius Meningitis: A Case Report

Incidence, Management, and Outcomes of Pediatric Infectious Aneurysms.

Infectious intracranial aneurysms (IIAs) are rare cerebrovascular complications of infective endocarditis (IE) accounting approximatively for 0.5% to 6.5% of all aneurysms. In children, mycotic aneurysms secondary to IE are uncommon. This is a retrospective study of patients treated for pediatric IIA secondary to IE at our institution with an emphasis on presentation, etiologies, nuances in management, and outcomes. One hundred fifty-one patients were treated for IE secondary to congenital or acquired heart disease, of which 13 patients (8.6%) presented with intracranial hemorrhage. IIA occurred in 5 patients (2.6%) with IE. IIA accounted for 15% of intracranial aneurysms treated during the study period. Pediatric patients with ruptured IIAs have a high rate of rerupture, and early surgical intervention should be considered through an open or endovascular route when available.

Impact of Combining Iliac Branch Endoprosthesis and Physician-Modified Fenestrated-Branched Endovascular Repair for Complex Abdominal and Thoracoabdominal Aortic Aneurysms with Concomitant Iliac Artery Aneurysms

Treatment of iliac artery aneurysms (IAA) with the Iliac Branch Endoprosthesis (IBE) during endovascular repair of infrarenal abdominal aortic aneurysm (EVAR) has been well-documented as effective. However, limited data exists evaluating the safety and efficacy of treating complex abdominal (cAAA) and thoracoabdominal aortic aneurysms (TAAA) with associated IAA with combined physician-modified fenestrated branched endovascular aortic repair (PM-FBEVAR) and IBE. Moreover, limited studies exist assessing the impact of adding IBE on the outcomes following PM-FBEVAR. Therefore, we compared the clinical outcomes of patients who underwent PM-FBEVAR with and without IBE for the treatment of cAAA and TAAA. A single institution retrospective review of consecutive patients who underwent PM-FBEVAR between September 2015 and February 2021 was conducted. Patients with both unilateral and bilateral IBE implantation were included. Infected aneurysms and pseudoaneurysms were excluded. Demographics, technical success, and operative factors were analyzed. Primary outcomes were incidence of pelvic ischemia including buttock and thigh claudication, bowel and spinal cord ischemia, patency of internal and external limbs of IBE, and target vessel instability. Secondary outcomes included technical success, 30-day major adverse events (MAE), 30-day and all-cause mortality, and endoleaks. Among 183 patients identified who underwent PM-FBEVAR, 22 patients underwent PM-FBEVAR and IBE with 3 patients treated with bilateral IBEs. There was no pelvic ischemia in the PM-FBEVAR and IBE group. Technical success, fluoroscopy time, and procedure time were comparable between the two groups. Contrast usage was higher in the PM-FBEVAR and IBE group (p=0.01). Thirty-day MAE and mortality were not statistically different between the two groups. At mean follow-up of 23 months, all-cause mortality was similar for both groups (21% vs 27%; p=0.47). Patency of internal iliac artery limb and external iliac artery limb of the IBE were 96% (24 of 25) and 100%, respectively, during mean follow-up of 23 months. The patient with occlusion of internal iliac limb was asymptomatic and received no re-intervention. Treatment of cAAA and TAAA associated with IAA using combined PM-FBEVAR and IBE is feasible with high efficacy and safety, and without adverse effect on outcomes. Long-term follow-up is planned to assess durability of repair with PM-FBEVAR and IBE.

Infectious endocarditis complicated with intracranial infected aneurysm rupture and sinus of valsalva aneurysm rupture

BackgroundInfectious endocarditis (IE) is an infectious disease caused by direct invasion of the heart valve, endocardium, or adjacent large artery endocardium by pathogenic microorganisms. Despite its relatively low incidence, it has a poor prognosis and a high mortality. Intracranial infectious aneurysms (IIA) and ruptured sinus of Valsalva aneurysm (RSVA) are rare complications of IE.Case presentationWe report a young male patient with symptoms of respiratory tract infection, heart murmurs and other symptoms and signs. The patient also had kidney function impairment and poor response to symptomatic therapy. Blood culture was negative, but echocardiography was positive, which met the diagnostic criteria for infective endocarditis. Moreover, an echocardiography showed a ruptured sinus of Valsalva aneurysm with a ventricular septal defect. Finally, secondary rupture of an IIA with multiple organ damage led to a poor clinical outcome.ConclusionTherefore, in the clinical setting, for young patients with unexplained fever, chest pain, or palpitations, we need to be highly vigilant, considering the possibility of infective endocarditis and promptly performing blood culture, echocardiography, cerebrovascular imaging and so on, in order to facilitate early proper diagnosis and treatment.

Outcomes of Endovascular Treatment for Infectious Thoracic Aortic Diseases

PurposeTo investigate the effectiveness and safety of thoracic endovascular aortic repair (TEVAR) for infectious aortic diseases. Materials and MethodsPatients who underwent TEVAR for infectious aortic diseases including infected thoracic aortic aneurysm, aortobronchial fistula (ABF), and aortoenteric fistula from December 2011 to October 2022 at 4 institutions were retrospectively studied. The primary outcome of the study was overall survival, whereas the secondary outcome was comprehensive adverse events. Comprehensive adverse events were defined as a combination of deaths, aortic events, and infectious adverse events. ResultsA total of 28 patients were included in the analysis, with 13 patients having infected thoracic aortic aneurysms, 12 ABFs, and 3 aortoenteric fistulae. Seven patients (25%) underwent additional procedures (abscess drainage, 6 cases; total esophagectomy, 1 case). The mean follow-up period was 30.0 months (SD ± 33.9). The 1-year and 5-year survival rates were 85.7% and 67.9%, respectively. The 1-year and 5-year aorta-related complication-free survival rates were 64.3% and 42.9%, respectively. On univariate analysis, the presence of an ABF was associated with a higher risk of comprehensive adverse events (odds ratio = 11; P = .04). ConclusionsTEVAR might be a promising treatment for infectious thoracic aortic diseases. Among the infectious pathologies, ABF was considered ominous in terms of late outcomes.

Combined Treatment of Ruptured Intracranial Infectious Aneurysm Accompanied by Intracerebral Hemorrhage: Endovascular Treatment and Neuroendoscopy

Intracranial infectious aneurysms (IIAs) are very rare. Most IIAs are associated with infective endocarditis (IE). The treatment of ruptured IIAs with intracerebral hemorrhage (ICH) remains challenging. Here, the authors aimed to describe a minimally invasive approach, combining endovascular treatment (EVT) with endoscopic techniques, for this complex issue. From January 2019 to December 2021, 3 cases of ruptured IIAs with intracerebral hemorrhage treated with EVT and neuroendoscopic hematoma evacuation at Guangdong Provincial People’s Hospital were included in this study. We retrospectively reviewed the clinical and imaging data and postoperative follow-up. All the IIAs were located in the middle cerebral arteries. The IIAs were secured by embolizing the aneurysms and occluding the parent artery. The ICH was evacuated using neuroendoscopy without postoperative rebleeding. After IIAs treatment, 2 patients underwent cardiac surgery, one at 10 days postoperatively and the other at 1 month postoperatively. At the 1-year follow-up, all patients resumed their normal lives. EVT and neuroendoscopic therapy for ruptured IIAs with ICH in patients is a useful complement to current treatment strategies.

Clinical and computed tomography angiography characteristics of infected vs. non-infected abdominal aortic aneurysm: a comparative study.

The aim of this study was to investigate the clinical and multi-slice spiral computed tomography angiography (MSCTA) characteristics for the diagnosis of infected AAA. This retrospective comparative study included patients who were diagnosed with AAA at our hospital between January 2014 and May 2023. A total of 40 patients were included, comprising 20 with infected AAA and 20 with non-infected AAA. Patients with infected AAA were more likely to be younger (62.9 ± 10.1 vs. 70.0 ± 4.4 years, P = 0.007) and to present with fever [7 (35%) vs. 1 (5%), P = 0.026], pain [15 (75%) vs. 2 (10%), P < 0.001], higher C-reactive protein levels (60.4 ± 57.0 vs. 4.1 ± 2.9mg/l, P = 0.005), and higher erythrocyte sedimentation rates (47.7 ± 23.4 vs. 15.2 ± 8.3mm/h, P < 0.001) compared to those with non-infected AAA. Moreover, those with infected AAA exhibited significantly more eccentric saccular morphology [17 (85%) vs. 1 (5%), P = 0.002], a smaller longitudinal-transverse ratio (1.12 ± 0.33 vs. 2.33 ± 0.54, P = 0.001), thicker peri-aneurysmal soft tissue (2.29 ± 1.48 vs. 0.73 ± 0.55cm, P < 0.001), more lobulated margins [18 (90%) vs. 1 (5%), P = 0.001], lower aortic calcification scores (49 vs. 56, P < 0.001), more pneumatosis [6 (30%) vs. 0 (0%), P = 0.014], more ruptures [15 (75%) vs. 5 (20%), P = 0.002], more blurred peri-abdominal aortic fat spaces [16 (80%) vs. 2 (10%), P = 0.001], more adjacent bone destruction [5 (25%) vs. 0 (0%), P = 0.025], more involvement of the psoas major muscle [8 (40%) vs. 1 (5%), P = 0.005], more lymphadenectasis [8 (40%) vs. 1 (5%), P = 0.020], and less tortuous aortas [2 (10%) vs. 9 (45%), P = 0.034] compared with those with non-infected AAA. The clinical manifestations and MSCTA characteristics may differ between infected and non-infected AAA.

Spontaneous Non-Aneurysmal Convexity Subarachnoid Hemorrhage: A Scoping Review of Different Etiologies beyond Cerebral Amyloid Angiopathy.

Spontaneous convexity subarachnoid hemorrhage (cSAH) is a vascular disease different from aneurysmal SAH in neuroimaging pattern, causes, and prognosis. Several causes might be considered in individual patients, with a limited value of the patient's age for discriminating among these causes. Cerebral amyloid angiopathy (CAA) is the most prevalent cause in people > 60 years, but reversible cerebral vasoconstriction syndrome (RCVS) has to be considered in young people. CAA gained attention in the last years, but the most known manifestation of cSAH in this context is constituted by transient focal neurological episodes (TFNEs). CAA might have an inflammatory side (CAA-related inflammation), whose diagnosis is relevant due to the efficacy of immunosuppression in resolving essudation. Other causes are hemodynamic stenosis or occlusion in extracranial and intracranial arteries, infective endocarditis (with or without intracranial infectious aneurysms), primary central nervous system angiitis, cerebral venous thrombosis, and rarer diseases. The diagnostic work-up is fundamental for an etiological diagnosis and includes neuroimaging techniques, nuclear medicine techniques, and lumbar puncture. The correct diagnosis is the first step for choosing the most effective and appropriate treatment.

Splenic abscess and infective endocarditis.

To determine the background, bacteriological, clinical and radiological findings, associated lesions, treatment and outcome of splenic abscesses (SAs) in infective endocarditis (IE). Retrospective study (2005-2021) of 474 patients with definite IE. The diagnosis of SA was made in 36 (7.6%) patients (31, 86.1%, males, mean age = 51.3) on abdominal CT. The main implicated organisms were Streptococcus spp (36.1%), Enterococcus faecalis (27.7%), Staphyloccus spp (19.4%). Rare agents were present in 10 patients (27.8%). Pre-existing conditions included a prosthetic valve (19.4%), previous IE (13.9%), intravenous drug use (8.4%), diabetes (25%) alcohol abuse (13.9%), liver disease (5.5%). Vegetations ≥ 15mm were present in 36.1%. Common presentations were abdominal pain (19.4%) and left-sided pleural effusion (16.5%). SA were more often small (50%; 7 multiple) than large (36.1%; 1 multiple) or microabscesses (13.9%, 3 multiple). Associated complications were extrasplenic abscesses (brain, 11.1%; lung, 5.5%; liver, 2.8%), infectious aneurysms (16.7%: 3 intracranial, 1 splenic, 1 hepatic, 1 popliteal), emboli (brain, 52.8%; spleen, 44.4%, 5 evolving to SA; kidney, 22.2%; aorta, 2.8%), osteoarticular infections (25%). Twenty-eight (77.8%) patients only received antimicrobials, 7 (19.4%) underwent splenectomy, after cardiac surgery in 5. One had percutaneous drainage. The outcome was uneventful (follow-up 3months-14years; mean: 17.2months). In SA-IE patients, the prevalence of vegetation size, Enterococcus faecalis, rare germs, diabetes, osteo-arthritic involvement and cancer was higher than in non-SA patients. Some SAs developed from splenic infarcts. IE-patients with evidence of splenic emboli should be evaluated for a possible abcedation. Cardiac surgery before splenectomy was safe.

Newly formed and ruptured infectious intracranial aneurysm in few days following first intracranial aneurysm embolization concurrent with middle cerebral artery occlusion: A regrettable case in a baby child

AbstractInfectious intracranial aneurysm (IIA) and embolic cerebral infarction are well‐known devastating complications of children suffering infective endocarditis. In this report, we describe a successfully embolized IIA concurrent with bilateral middle cerebral artery (MCA) occlusion. Unfortunately, a newly formed IIA located in the contralateral MCA bifurcation ruptured at the seventh day following embolization. A 6‐month‐old female child was admitted to hospital 3 days following acute right limb mobility disorder. An interventional surgery history of congenital heart disease was confirmed. She was immediately started on antibiotic therapy and the computed tomography agiography (CTA) scan showed occlusion of the upper branch of the left MCA. Unfortunately an IIA was located in the distal artery region (DAR) of the ipsilateral anterior cerebral artery. Angiography (digital subtraction angiography) was performed and the DAR IIA was embolized by OnyX‐18 with Magic 1.2 Fr. microcatheter. On the sixth day, magnetic resonance imaging during the hospital stay showed reduced infarction area with no other special sign. Desperately, a major seizure with opisthotonos attacked the baby on the seventh day after embolization. An immediate CTA scan showed massive hematoma in the right basal ganglia and a ruptured bifurcate aneurysm of the right MCA. The parents refused positive treatment and discharged in considering the critical situation. It should be noted that IIA can be fast formed anywhere in cerebral artery and dynamic angio‐image should be performed as supervision.

Infective Native Aortic Aneurysm: a Delphi Consensus Document on Treatment, Follow Up, and Definition of Cure

Abstract Background Evidence is lacking to guide the management of infective native aortic aneurysm (INAA). Aims The aim of this study was to establish expert consensus on surgical and antimicrobial treatment and follow up, and to define when an INAA is considered cured. Methods Delphi methodology was used. The principal investigators invited 47 international experts (specialists in infectious diseases, radiology, nuclear medicine, and vascular and cardiothoracic surgery) via email. Four Delphi rounds were performed, 3 weeks each, using an online questionnaire with initially 28 statements. The panelists rated the statements on a 5-point Likert scale. Comments on statements were analysed, statements were revised and added or deleted, and the results were presented in the iterative rounds. Consensus was defined as ≥ 75% of the panel rating a statement as strongly agree or agree on the Likert scale, and consensus on the final assessment was defined as Cronbach’s α &amp;gt; 0.80. Results All 49 panelists fulfilled all four rounds, resulting in 100% participation. One statement was added based on the results and comments of the panel, resulting in 29 final statements: n = 3 on need for consensus, n = 20 on treatment, n = 5 on follow up, and n = 1 on definition of cure. All 29 statements reached agreement of ≥ 86%. Cronbach’s α increased for each consecutive round; round 1, 0.85; round 2, 0.90; round 3, 0.91; and round 4, 0.94. Thus, consensus was reached for all statements. Conclusion INAA is rare, and high-level evidence is lacking to guide optimal management. This consensus document was established with the aim of helping clinicians manage these challenging patients, as a supplement to current guidelines. The presented consensus will need future amendments in accordance with newly acquired knowledge.

Infective Native Aortic Aneurysms: A Delphi Consensus Document on Terminology, Definition, Classification, Diagnosis, and Reporting Standards

Abstract Background There is no consensus regarding the terminology, definition, classification, diagnostic criteria, and algorithm, or reporting standards for the disease of infective native aortic aneurysm (INAA), previously known as mycotic aneurysm. Aims The aim of this study was to establish this by performing a consensus study. Methods The Delphi methodology was used. Thirty-seven international experts were invited via mail to participate. Four two-week Delphi rounds were performed, using an online questionnaire, initially with 22 statements and nine reporting items. The panellists rated the statements on a five-point Likert scale. Comments on statements were analysed, statements revised, and results presented in iterative rounds. Consensus was defined as ≥ 75% of the panel selecting “strongly agree” or “agree” on the Likert scale, and consensus on the final assessment was defined as Cronbach's alpha coefficient &amp;gt; .80. Results All 38 panellists completed all four rounds, resulting in 100% participation and agreement that this study was necessary, and the term INAA was agreed to be optimal. Three more statements were added based on the results and comments of the panel, resulting in a final 25 statements and nine reporting items. All 25 statements reached an agreement of ≥ 87%, and all nine reporting items reached an agreement of 100%. The Cronbach's alpha increased for each consecutive round (round 1 = .84, round 2 = .87, round 3 = .90, and round 4 = .92). Thus, consensus was reached for all statements and reporting items. Conclusion This Delphi study established the first consensus document on INAA regarding terminology, definition, classification, diagnostic criteria, and algorithm, as well as reporting standards. The results of this study create essential conditions for scientific research on this disease. The presented consensus will need future amendments in accordance with newly acquired knowledge.

Hepatic Artery Aneurysms in Infective Endocarditis: Report of 10 Cases and Literature Review

Hepatic artery aneurysms (HAAs), albeit rare in infective endocarditis (IE), are associated with a life-threatening morbidity. 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. 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 11.7mm (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 <15mm 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. Abdominal CTA was pivotal in the initial IE workup. Small aneurysms (≤15mm) resolved under antibiotherapy. The usual treatment modality was HAA embolization and endovascular embolization before valve surgery was safe.

A Rare Case of Infective Aneurysm of Mesenteric Artery Due to Infective Endocarditis: Diagnosis and Treatment

The infected aneurysm is a rare disease; antibiotic therapy combined with surgical treatment is the most common treatment currently available after computed tomography (CT) imaging and blood culture confirmation. We herein report a case of a 25-year-old male with infective endocarditis that caused an infective aneurysm of the mesenteric artery. We hope to help with the diagnosis and treatment of similar patients.

Long-term outcomes of stapled closure of the aortic stump with axillo-bifemoral bypass grafting for abdominal aortic infection

ObjectivesThe stapled suture is used to close the aortic stump during surgery for abdominal aortic infection. The current study aimed to investigate the short- and long-term outcomes of stapled closure of the aortic stump with axillo-bifemoral (AxBF) bypass grafting. MethodsThe short- and long-term outcomes of 11 patients who underwent surgery for abdominal aortic infection were retrospectively analyzed. ResultsOf 11 patients, 7 underwent stapled closure of the aortic stump with AxBF bypass grafting, and four underwent other reconstructive procedures with no aortic stump. Four patients (three who underwent stapled closure of the aortic stump and one who underwent other reconstructive procedures without the aortic stump) had operative death. However, none of the patients had aortic stump blow-out during the same hospitalization for surgery. The 1- and 5-year survival rates of the patients who underwent stapled closure of the aortic stump with AxBF bypass grafting were 57% and 29%, respectively. One patient developed aorto-duodenal fistula at 32 months after surgery. The patient survived for 12 months until bleeding in the recurrent aorto-enteric fistula occurred. ConclusionStapled closure of the aortic stump is durable. The use of a linear stapler is a useful technique for reinforcing the aortic stump in patients who underwent excision of an infected abdominal aortic aneurysm or an infected abdominal graft.
