RESUMO
Background: Biomarkers can be measured in various biological samples. Urine is among the most useful biofluids for routine testing, and several experimental and clinical studies support its role as a tool for the diagnosis and prevention of various diseases. The present systematic review aimed to examine periodontitis-specific urine biomarkers that could have a diagnostic relevance and to provide a qualitative assessment of the current literature. Materials and Methods: Relevant studies identified from PubMed, Embase, Cochrane Library, and Scopus databases were examined to answer the following PECO question: "Could the concentration of specific metabolites in the urine be related to periodontal health and what is their diagnostic accuracy?". Quality of included studies was rated using ROBINS-I tool. Meta-analysis was conducted on available quantitative data. Results: After the screening of 768 titles, five studies were included in qualitative synthesis. The studies included referred to the evaluation of 8-hydroxy-2'-deoxyguanosine (8-OHdG) and neopterin. Meta-analysis was conducted for neopterin concentration on data available in four studies involving 129 participants. Higher concentrations of neopterin were found in periodontitis-affected patients compared to controls and patients treated for periodontitis. Conclusions: The literature appears controversial in attributing a role to neopterin and 8-OHdG as periodontal biomarkers, highlighting the need for further clinical studies on this topic. While some studies report variations in 8-OHdG and neopterin levels in periodontally affected patients versus either controls or periodontally treated patients, the level of evidence appears still limited to draw firm conclusions (PROSPERO CRD42020222681).
RESUMO
BACKGROUND: The present systematic review evaluated clinical and radiographic features and treatment outcomes of peri-implantitis-induced medication-related osteonecrosis of the jaws (Pi-MRONJ). MATERIALS AND METHODS: Literature search was performed in PubMed/MEDLINE, Cochrane CENTRAL, Web of Science, and Scopus databases. Studies reporting Pi-MRONJ were included. No time restrictions were applied. RESULTS: In total, 571 articles were retrieved, and 24 articles were included in the final review. Study population consisted of 111 patients (70% pharmacologically treated for osteoporosis and 30% for oncologic disease). Pi-MRONJ was characterized by pain, bone exposure and suppuration, and involved a single implant in 55 cases, two implants in 37 cases, three implants in 10 cases, and more than four implants in nine cases. Most of the lesions were assigned Stage II and III. MRONJ developed on average 46.5 ± 33.2 months following implant placement. Sixty-one lesions were surgically treated with implant removal and debridement of the surrounding necrotic bone. Complete wound healing was observed in 85% of cases. CONCLUSIONS: The presence of dental implants in patients treated with antiresorptive drugs should be considered as a potential risk factor for MRONJ onset. In cases of periimplantitis with delayed wound healing following nonsurgical therapy, the clinician should rule out the presence of Pi-MRONJ.
RESUMO
OBJECTIVES: This single-center randomized, parallel design, clinical trial with a 2-week follow-up involved patients affected by periodontitis undergoing periodontal surgery. The aim was to evaluate periodontal surgical wound healing with the use of chlorhexidine-based mouth rinses versus an untreated control group. MATERIALS AND METHODS: Periodontal surgery was performed following a standardized protocol. Patients were randomly prescribed i) chlorhexidine (CHX) + anti-discoloration system (ADS) + hyaluronic acid (HA), ii) CHX + ADS or iii) no treatment (control group). Plaque score, gingival inflammation, and Early Healing Index (EHI), assessing the degree of wound closure and the presence of fibrin and necrosis, were evaluated at 3, 7 and 14 days after surgery. RESULTS: In total, 33 patients were enrolled. Patients were comparable at baseline for all measured clinical parameters. At 3-days wound healing was significantly improved in all patients treated with CHX + ADS-based mouth rinses with a lower EHI score at the interdental papillae compared with control group (p < 0.01). CHX + ADS + HA group presented improved healing across all time points in terms of EHI, plaque containment, and gingival inflammation when compared to control group (p < 0.01). CONCLUSIONS: The usage of CHX-ADS following periodontal surgery improved early wound healing, reduced plaque accumulation and gingival inflammation. During the early post-operative period the adjunct of HA further improved soft tissue closure. CLINICAL RELEVANCE: This study aims at evaluating the response of gingival tissues to mouth rinsing with chlorhexidine and anti-discoloration system (CHX + ADS) or CHX + ADS + hyaluronic acid (CHX + ADS + HA) versus no rinse in terms of healing of the periodontal surgical wound. CHX + ADS mouth rinses enhanced early soft tissue closure after periodontal surgery and contributed to the reduction in plaque accumulation and gingival inflammation. The adjunct of HA may be beneficial especially in the early post-operative period. CHX + ADS administration following periodontal surgery may improve soft tissue healing in the first two post-operative weeks.

Objectives: Primary Sjögren's syndrome (pSS) is a chronic autoimmune disorder characterized by dryness of mucous membranes, predominantly the eyes and mouth, following glandular tissue substitution. The onset of oral dryness constitutes a significant source of discomfort that negatively affects overall quality of life. This systematic review aimed at investigating the differences in Oral Health Impact Profile-14 (OHIP-14) questionnaire scores in patients diagnosed with Sjögren's syndrome compared to sicca syndrome, to assess the influence of the two conditions on oral health. Study Design. A systematic electronic and manual search was performed up to December 2023 for studies reporting OHIP-14 questionnaire scores in pSS patients versus sicca syndrome. Two authors independently reviewed, selected, and extracted the data. The outcome was the assessment of OHIP-14 scores in studies comparing pSS- and sicca syndrome-affected patients. Meta-analysis was conducted on available quantitative data. Results: Literature search retrieved 30 articles, and 3 articles met the criteria for inclusion in the review. Meta-analysis revealed significantly higher scores in patients with sicca syndrome compared to pSS, although salivary flow was markedly reduced in pSS. Conclusions: While offering supplementary information to standard tests and supporting the assessment of pSS and sicca syndrome patients, further validation is necessary to establish OHIP-14 validity in determining the impact of pSS and sicca syndrome on patients' quality of life.
RESUMO
Muscular temporomandibular joint disorders (M-TMDs) encompass a wide range of painful muscular conditions, which can provoke functional limitation and severely affect quality of life. The aim of the present study was to assess the treatment outcomes in patients affected by M-TMDs in terms of pain scores assessed with pressure pain threshold (PPT). The levels of depression, anxiety, and the Oral Health Impact Profile were also assessed and compared to healthy controls. Patients with a clinical diagnosis of M-TMDs and a control group of healthy subjects were enrolled. At baseline, OHIP-14, PHQ-9, and GAD-7 were administered. PPT was registered at the level of masseter and temporalis muscles. The patients affected by M-TMDs were then treated with oral splints and physio-kinesiotherapy following a standardized treatment protocol. At the 6-month follow-up of M-TMD-affected patients, PPT was registered, and the questionnaires were re-administered to evaluate treatment outcomes. In total, sixty patients and sixty controls were enrolled. The treatment of M-TMDs produced a significant improvement in PPT at the level of the masseter muscle. OHIP-14 at baseline in the M-TMD group was significantly higher compared to the control group (p < 0.05). At the 6-month follow-up, a significant reduction in OHIP-14 scores was registered, although with higher scores compared to the control group (p < 0.05). PHQ-9 was significantly higher at baseline in the M-TMD group (p < 0.05) and decreased to values comparable to the control group after treatment. GAD-7 presented statistically significant differences between the control group and M-TMD patients at baseline (p < 0.05) and between pre- and post-treatment in the M-TMD group. Following treatment, the GAD-7 scores were comparable to the control group. The symptom burden associated with M-TMDs negatively affects quality of life, with higher oral health impairment and a tendency towards depression and anxiety compared to healthy subjects. Following treatment, an improvement in both PPT and quality of life was observed.
RESUMO
PURPOSE: To evaluate the influence of endograft fixation type on the incidence, treatment, and outcomes of type III endoleaks (TIIIELs). MATERIALS AND METHODS: Abdominal aortic aneurysms (AAAs) treated with bifurcated endografts between 1994 and 2020 were prospectively collected and reviewed. The endograft included were classified as "Anatomical Fixation" (AF) (Powerlink [Endologix] and AFX [Endologix]) or "Proximal Fixation" (PF). The primary outcome was the incidence of TIIIEL over time, stratified by fixation type. Secondary outcomes included between-group comparisons of baseline characteristics, intraoperative details during TIIIEL correction, and survival analysis after TIIIEL diagnosis. RESULTS: A total of 2065 endovascular aneurysm repairs were performed: 872 (42.2%) with AF and 1193 (57.8%) with PF devices. The estimated incidence of TIIIEL at 1, 5, and 10 years was 0.4%, 4.2%, and 7.3%, and 0.5%, 3.2%, and 4.6% for AF and PF, respectively (p=0.157), and fixation type was not associated with TIIIEL development in the competing risk regression model (p=0.101). The cumulative overall survival rate in patients diagnosed with TIIIEL did not differ significantly between the groups (p=0.077). The rate of recurrent TIIIELs was significantly lower in the AF group (7.1% vs 22.7%; p=0.044); however, no significant difference was found in secondary reintervention between the two groups (11.9% vs 27.3%, p=0.074). Patients with angulated and calcified aortic neck (SHR 3.4, 95% CI 1.2-9.6, p=0.022) and larger aneurysms (SHR 1.2; 95% CI 1.1-1.3; p<0.001) had a higher risk of TIIIEL. Likewise, the use of three or more endograft components increased the risk of TIIIEL by 3.1 times (SHR 3.1; 95% CI 1.7-5.4; p<0.001). CONCLUSIONS: The occurrence of TIIIELs was not affected by the type of endograft fixation. For larger abdominal aortic aneurysms (AAAs) and aneurysms with angulated and calcified aortic necks, there is a higher likelihood of developing TIIIELs during follow-up, regardless of the endograft type used. CLINICAL IMPACT: The type of fixation does not influence the incidence of TIII ELs. EVAR in larger AAAs and aneurysms with angulated and calcified aortic necks have a higher risk of developing TIII EL. Moreover, the risk of TIII EL is considerably increased by the use of three or more modular components.
RESUMO
OBJECTIVE: This study aimed to compare two commercially available off the shelf branched endografts for thoraco-abdominal aortic aneurysm (TAAA) repair, namely the E-nside (Artivion) and Zenith t-Branch (Cook Medical) devices. METHODS: This multicentre retrospective study (2020 - 2023) included patients treated by branched endovascular aortic repair (BEVAR) for TAAA using the inner branched E-nside or the outer branched t-Branch. Endpoints were 30 day technical success and major adverse events (MAEs) as well as one year freedom from target vessel instability and main endograft instability. RESULTS: The study included 163 patients: 79 (307 target vessels) treated with E-nside and 84 (325 target vessels) with t-branch. Aneurysm extent was I - III in 91 patients (55.8%; 47% of E-nside and 66% of t-Branch) and IV in 72 patients (44.2%; 53% of E-nside and 34% of t-Branch) (p = .011). An adjunctive proximal thoracic endograft was used in 43% of E-nside vs. 69% of t-Branch (p < .001), with less frequent thoracic endografting (14% vs. 76%; p < .001) and shorter length of coverage (p = .024) in extent IV TAAA treated by E-nside. E-nside cases had shorter renal artery bridging lengths (66 ± 17 mm vs. 76 ± 20 mm; p < .010) and less frequent use of a distal bifurcated endograft (53% vs. 80%; p < .001). Comparing 30 day results, the mortality rate was 1% vs. 2% (p = .62), any MAE occurred in 18% vs. 21% (p = .55), the stroke rate was 3% vs. 0% (p = .23), and the elective spinal cord ischaemia rate was 5% vs. 8% (p = .40) for E-nside and t-Branch, respectively. At one year, freedom from target vessel instability was 96 ± 3% for E-nside and 95 ± 3% for t-Branch (p = .58), and freedom from endograft instability was 98 ± 2% vs. 97 ± 3% (p = .46), respectively. CONCLUSION: Both off the shelf devices provided excellent early and one year results. The E-nside may require shorter thoracic aortic coverage and bridging length for the renal arteries, and less frequent implantation of a concomitant proximal thoracic or distal abdominal bifurcated endograft. However, these aspects did not determine significant differences in clinical outcomes.

OBJECTIVE: This study aimed to investigate the incidence of cerebrospinal fluid drainage (CSFD)-related complications specifically in patients who underwent fenestrated and branched endovascular aortic repair (F/B-EVAR). This objective was chosen considering the limitations and uncertainties surrounding its efficacy in preventing spinal cord injury. METHODS: A systematic review following Cochrane Handbook and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted (PROSPERO; #CRD42022359223). Literature searches of MEDLINE, Embase, and Scopus were performed until May 1, 2023, focusing on studies published after January 1, 2000. The inclusion criteria encompassed studies reporting on F/B-EVAR, CSFD, and drain-related complications. Data extraction and quality assessment using the Newcastle-Ottawa Scale were performed by multiple reviewers to ensure accuracy and reliability. A proportion meta-analysis was conducted to calculate the pooled rate and 95% confidence interval (CI). The primary and secondary outcomes were CSFD-related mortality and morbidity, respectively. RESULTS: Six retrospective, observational, single-center studies were included, totaling 1079 patients and 730 CSFD placements (all prophylactic except for one). The Newcastle-Ottawa Scale showed a high to moderate risk of bias. The analysis revealed a CSFD-related mortality rate of 1.4% (95% CI: 0.0-4.8; I2 = 67.7%) and an overall morbidity rate of 25.6% (95% CI: 13.6-39.7; I2 = 83.2%). The overall major, moderate, and minor estimated complication rates were 6.1% (95% CI: 4.1-8.5; I2 = 0%), 4.6% (95% CI: 2.4-7.3; I2 = 33.5%), and 26.4% (95% CI: 16.5-37.7; I2 = 84.9%), respectively. Severe complications included intracranial hemorrhage (2.8%), spinal hematoma (1.4%), subarachnoid hemorrhage (1.4%), and CSFD-related neurological deficits (1.1%). A pooled estimate of 11.4% for nonfunctioning drainage was found. CONCLUSIONS: F/B-EVAR patients showed a notable incidence of CSFD-related death and substantial morbidity. This study highlights the limitations of the available data, the high prevalence of complications associated with CSFD, and the need for further research to better understand the risks and benefits of CSFD in F/B-EVAR. This calls for careful consideration regarding the routine use of prophylactic drainage due to the accumulating evidence of the risks associated with CSFD without proven benefit in this specific context.

OBJECTIVE: The use of intravascular ultrasound (IVUS) reduces contrast medium use and radiation exposure during conventional endovascular aneurysm repair (EVAR). The aim of this study was to evaluate the safety and efficacy of IVUS in detecting bridging stent graft (bSG) instability during fenestrated and branched EVAR (F/B-EVAR). METHODS: This was a prospective observational multicentre study. The following outcomes were evaluated: (1) technical success of the IVUS in each bSG, (2) IVUS findings compared with intra-operative angiography, (3) incidence of post-operative computed tomography angiography (CTA) findings not detected with IVUS, and (4) absence of IVUS related adverse events. Target visceral vessel (TVV) instability was defined as any branch or fenestration issues requiring an additional manoeuvre or re-intervention. Any IVUS assessment that detected stenosis, kinking, or any geometric TVV issue was considered to be branch instability. All procedures were performed in ad hoc hybrid rooms. RESULTS: Eighty patients (69% males; median age 72 years; interquartile range 59, 77 years) from four aortic centres treated with F/B-EVAR between January 2019 and September 2021 were included: 70 BEVAR (21 off the shelf; 49 custom made), eight FEVAR (custom made), and two F/B-EVAR (custom made), for a total of 300 potential TVVs. Two TVVs (0.7%) were left unstented and excluded from the analysis. The TVVs could not be accessed with the IVUS catheter in seven cases (2.3%). Furthermore, 17 (5.7%) TVVs could not be examined due to a malfunction of the IVUS catheter. The technical success of the IVUS assessment was 91.9% (274/298), with no IVUS related adverse events. Seven TVVs (2.5%) showed signs of bSG instability by means of IVUS, leading to immediate revisions. The first post-operative CTA at least 30 days after the index procedure was available in 268 of the 274 TVVs originally assessed by IVUS. In seven of the 268 TVVs (2.6%) a re-intervention became necessary due to bSG instability. CONCLUSION: This study suggests that IVUS is a safe and potentially valuable adjunctive imaging technology for intra-operative detection of TVV instability. Further long term investigations on larger cohorts are required to validate these promising results and to compare IVUS with alternative technologies in terms of efficiency, radiation exposure, procedure time, and costs.

The objective of these Guidelines is to provide recommendations for the classification, indication, treatment and management of patients suffering from aneurysmal pathology of the visceral and renal arteries. The methodology applied was the GRADE-SIGN version, and followed the instructions of the AGREE quality of reporting checklist. Clinical questions, structured according to the PICO (Population, Intervention, Comparator, Outcome) model, were formulated, and systematic literature reviews were carried out according to them. Selected articles were evaluated through specific methodological checklists. Considered Judgments were compiled for each clinical question in which the characteristics of the body of available evidence were evaluated in order to establish recommendations. Overall, 79 clinical practice recommendations were proposed. Indications for treatment and therapeutic options were discussed for each arterial district, as well as follow-up and medical management, in both candidate patients for conservative therapy and patients who underwent treatment. The recommendations provided by these guidelines simplify and improve decision-making processes and diagnostic-therapeutic pathways of patients with visceral and renal arteries aneurysms. Their widespread use is recommended.

OBJECTIVE: We assessed the suitability of two triple branch arch devices (aBranch) (Terumo aortic and Cook Medical) and a balloon-expandable covered stent (VBX, W. L. Gore & Associates, Johnson & Johnson) to incorporate the brachiocephalic trunk (BCT) in a cohort previously treated with hybrid thoracic endovascular repair (TEVAR). METHODS: This is a single-center, retrospective, all-comers, preclinical suitability study. We conducted an analysis of preoperative computed tomography scans in surgical patients between 1999 and 2022 in a single vascular surgery unit. The primary outcome was the aortic suitability of aBranch devices and VBX as mating stent for BCT in previous hybrid TEVAR. Hybrid repair of the aortic arch included TEVAR, fenestrated or branched TEVAR associated with any surgical debranching of the supra-aortic trunks and chimney TEVAR with proximal landing in zones 0 to 2. Secondary outcomes included (i) suitability assessment when excluding minor instruction for use (IFU) criteria, (ii) a comparison of suitable and nonsuitable patients, (iii) risk factors analysis for nonsuitability, and (iv) a description of the exclusion causes. RESULTS: During the study period, 120 patients were treated. Among elective patients (n = 73), the suitability of any aBranch was 82.2% (60/73) and VBX was suitable in 64.4% of BCTs (47/73). The aBranch suitable patients had a significantly longer sinotubular-BCT length (P = .017) and smaller distal ascending aorta (P = .043) as compared with nonsuitable ones. The suitability of Terumo Aortic and Cook Medical devices was 52.1% (38/73) and 46.6% (34/73), respectively. When minor IFU criteria were ignored, suitability increased to 82.2% (60/73) and 63.0% (46/73), respectively. Left common carotid artery diameter and sinotubular-BCT length were significant nonsuitability risk factors for Terumo Aortic aBranch in multivariable analysis. No associations were found for Cook Medical device. The outcomes were tested in the entire cohort demonstrating a global suitability of 82.9%, increasing to 86.3% when ignoring minor IFUs. VBX was anatomically suitable to use in BCT in 73.2% of patient BCTs. CONCLUSIONS: aBranch devices are anatomically suitable in a vast majority of patients (86%) undergoing hybrid TEVAR. The innominate artery seems eligible for incorporation with VBX in almost two-thirds of patients. This mating stent may help to overcome some minor IFU restrictions.

OBJECTIVE: We compared the outcomes of patients treated with nonbare stents (NBS) and proximal bare stents (PBS) endografts with a proximal landing zone in the aortic arch during thoracic endovascular aortic repair (TEVAR). METHODS: We conducted a retrospective cohort, observational, multicenter study that included 361 consecutive TEVAR procedures undertaken between November 2005 and December 2021. TEVAR patients with both BS and NBS Relay stent graft configurations with proximal landing in zones 1, 2, or 3 were enrolled. Preoperative anamnestic and morphological data, clinical outcomes, and aortic modifications 30 days after surgery and at the latest follow-up available were collected. The primary outcome was freedom from proximal endoleak (type IA) comparing the two configurations. Total and detailed endoleak rates, clinical and technical success, intraoperative additional maneuvers, major adverse events, and reinterventions were secondary outcomes. RESULTS: The median follow-up was 4.9 (interquartile range, 2.0-8.1) years. No statistically significant difference between NBS and PBS patients concerning 30-day major adverse events, retrograde aortic dissection, disabling stroke, or late type IA endoleak (10.8% vs 7.8%; P = .597). Aneurysmal disease (P = .026), PLZ diameter of >34 mm (P = .026), aortic tortuosity index of >1.4 (P = .008), type III aortic arch (P = .068), and PLZ thrombus (P = .014) identified as risk factors by univariate Cox regression analysis. PLZ thrombus was the only type IA endoleak risk factor at multivariate Cox regression (P = .016). CONCLUSIONS: We found no statistically significant difference in freedom from type IA endoleak, retrograde dissection, or disabling stroke observed between the NBS and the BS configuration of the Relay endograft. Proximal landing zone thrombotic apposition was a prominent risk factor for type IA endoleak after TEVAR.

BACKGROUND: Endovascular treatment of thoracoabdominal aortic aneurysms has become common, with satisfactory results. Nevertheless, long-term durability remains an issue mainly because of target visceral vessel (TVV) instability. Currently, no covered stent has been approved as a bridging stent graft (BSG), demanding continuous research on this topic. METHODS: This was a multicenter observational retrospective cohort study comparing the midterm results of the Bard Covera Plus and Gore VBX as BSGs during branched endovascular aneurysm repair. The primary outcome was the comparison of the target vessel instability between the two groups. Primary patency, freedom from branch-related type I and III endoleaks and reintervention, and technical and clinical success were considered secondary outcomes. Logistic regression analysis was used to assess the association between selected baseline factors and TVV instability. TVV instability during follow-up was then evaluated using the Kaplan-Meier cumulative function. RESULTS: Three hundred forty-five TVVs in 106 patients were considered suitable for the analysis. Two hundred twenty vessels were stented with the Covera stent graft (64%) and 125 with VBX (36%). Two hundred ninety-nine TVVs received a single BSG, 45 two BSGs, and only 1 three BSGs. Bare metal stent relining was required in 36% of TVVs, mostly in the Covera group (89 [41%] vs 36 [29%]) (P = .030). The primary technical success rate was 96% (331/345), and the assisted primary technical success rate was 99% (342/345). The TVV instability rate within 30 days was 2% (one Covera and five VBX; P = .015). Three BSG occlusions (one Covera and two VBX) and three type Ic endoleaks (three VBX) were detected. The median follow-up was 13.9 months (range, 5.8-25.5 months). Sixteen TVV instabilities were detected during the follow-up. Twelve BSG occlusions (six Covera and six VBX), three type Ic endoleaks (one Covera and two VBX), and one type IIIc endoleak (VBX). The overall target vessel instability rate was 5% (16/342). TVV instability was associated with the use of Gore VBX in the univariable logistic regression (odds ratio, 3.0; 95% confidence interval, 1.1-8.0; P = .027). Aneurysm rupture and aneurysm diameter were also associated with TVV instability in the univariable analysis (P = .002 and P = .008, respectively). The only factor predisposing to TVV instability in the multivariable logistic regression analysis was the use of Gore VBX as a BSG (odds ratio, 2.9; 95% confidence interval, 1.0-8.0; P = .043). Kaplan-Meier analysis showed a significantly higher risk of TVV instability in the VBX group (P < .001). CONCLUSIONS: Overall midterm outcomes in this cohort were satisfactory. Patency rates were similar between the two stents. Nevertheless, VBX seems to be associated with worse TVV instability. These results may be correlated with a higher incidence of type Ic endoleaks, which require an extensive learning curve for correct stent selection and deployment.

We report a multicenter experience of open conversions (OC) for aortic endograft infections (AEI). We retrospectively analyzed all patients who underwent OC for AEI after endovascular aneurysm repair (EVAR), from 1997 to 2021 in 12 Italian centers. The endpoints were as follows: mortality (30-days, in-hospital), major postoperative complications. Follow-up data included: survival, aortic-related complications, infection persistence or reoccurrence. Fifty-eight patients (mean age: 73.8 ± 6.6 years) were included. Median time from EVAR to OC was 14 months (interquartile range 7-45). Thirty-five patients (60.3%) were symptomatic at presentation. Aortic reconstruction was anatomic in 32 patients (55.2%), extra-anatomic in 26 (44.8%). Thirty-day mortality was 31% (18/58). Six additional patients died after 30 days during the same hospitalization (in-hospital mortality: 41.4%). Most common post-operative complications included respiratory failure (38.6%) and renal insufficiency (35.1%). During 28.1 ± 4 months follow-up, 4 aneurysm-related deaths were recorded. Infection re-occurred in 29.4% of the patients. Estimated survival was 50% at 1 year, and 30% at 5 years, and was significantly lower for patients who underwent extra-anatomic reconstructions (37 vs 61% at 1 year, 16 vs 45% at 5 years; log-rank P = .021). OC for AEI is associated with high early mortality. The poor mid-term survival is influenced by aortic complications and infection re-occurrence.
RESUMO
Depth of invasion (DOI) has been recognized to be a strong prognosticator for oral squamous cell carcinoma (OSCC). Several diagnostic techniques can be employed for DOI assessment, however intraoral ultrasonography has been increasingly applied for the intraoral evaluation of OSCCs. The aim of the present study is to review the evidence on the application of intraoral ultrasonography to the assessment of DOI in patients affected by OSCC. A systematic electronic and manual literature search was performed, and data from eligible studies were reviewed, selected, and extracted. The studies had to report the correlation between DOI estimated with ultrasonography versus histopathology. A meta-analysis was conducted on the quantitative data available. Sixteen articles were included in the review following the screening of the initial 228 studies retrieved from the literature. The meta-analysis showed a significant correlation between ultrasonographic and histopathologic measurements (p < 0.01). The studies were all at low/moderate risk of bias. Ultrasonography appears a valuable tool for DOI assessment.
RESUMO
OBJECTIVES: The aim of this study was to evaluate the suitability of a subclavian unibody single-branch endograft among patients treated with thoracic endovascular aortic repair (TEVAR) in landing zone 2 (LZ2). METHODS: This is a pre-clinical, single-centre, real-world, all-comers, retrospective cohort study. Patients treated with TEVAR in LZ2 with an available preoperative computed tomography angiography were included. The primary outcome was the anatomical feasibility of the Castor endograft in patients receiving endovascular treatment in LZ2 between 1999 and 2022. Secondary outcomes were: a comparison of feasible and unfeasible patients; frequencies and description of exclusion causes; non-feasibility risk factor analysis; and analysis of the stent graft configurations necessary to treat 75% of the patients. A logistic regression model was used to find associations between baseline morphological data and non-feasibility. RESULTS: A total of 473 procedures were performed and 72 patients fulfilling inclusion criteria were included. The mean distance between the left carotid artery and left subclavian artery (or between innominate artery and bovine trunk) was 12.4 ± 5.2 mm and its average diameter was 33.0 ± 10.6 mm. The pre-vertebral left subclavian artery's diameter and length were 11.3 ± 2.5 and 38.7 ± 10.8 mm. Forty-nine (68.1%) patients were suitable for Castor implantation. Twenty-one configurations were required to treat 75% of feasible patients and might be lowered to 12 configurations applying less strict criteria. CONCLUSIONS: The Castor endograft was anatomically feasible in several patients requiring TEVAR in LZ2. Three-quarters of feasible patients could be treated with a reasonable number of configurations, paving the path for future off-the-shelf applications.

OBJECTIVES: To evaluate the feasibility of a standardized single-renal scallop stent-graft. DESIGN: Preclinical, single-center, real-world, all-comers, retrospective cohort study. METHODS: A total of 1347 abdominal aortic aneurysm (AAA) repairs (endovascular and open) performed between 2010 and 2020 were screened for elective treatment and retrievable preoperative high-quality computed tomography angiography (CTA) performed <6 months of the surgical procedure. Six hundred of the included CTAs involved prespecified measurements and a morphological assessment protocol (NCT05150873). The proximal sealing zones suitable for standard stent-graft implantations were further analyzed (N=547). The primary outcome assessed the feasibility of 2 single-renal scallop designs (10×10 mm and 15×10 mm, height × width). The feasibility was the inter-renal length ≥10 mm and ≥15 mm for prototypes #10 and #15, respectively. The secondary outcome quantified hypothetical length and surface improvements comparing those suitable for investigational devices implantation (study group) versus those not (control group). RESULTS: Of the total, 24.7% (n=135) was feasible with prototype #10. The study versus control group sealing zones were shorter (p=0.008), with a smaller surface (p=0.009) and a higher alpha angle (p=0.039). The length and surface area increased by about 25% and 23%, respectively, (both p<0.001) within the study group and became significantly better versus the control group (standard stent-graft; both p<0.001). Of the total, 7.1% (n=39) was suitable for prototype #15. The study versus control group sealing zones were shorter (p=0.148), with a smaller surface (p=0.077) and a higher alpha angle (p=0.027). The length and surface area increased by about 34% and 31%, respectively, (both p<0.001) within the study group and became significantly higher versus the control group (standard stent-graft; both p<0.001). CONCLUSIONS: The use of single-renal scalloped stent-graft might be feasible in a considerable number of AAA patients. The breakthrough stands in treating hostile AAAs presenting in mismatched renal arteries, keeping the complexity of the repair as similar as possible to standard endovascular repair with a remarkable improvement in sealing. CLINICAL IMPACT: The anatomic feasibility of a single renal stent graft for the treatment of "hostile" abdominal aortic aneurysm (AAA) with mismatched renal arteries was evaluated. The experimental device could be feasible in a considerable number of patients with AAA, approaching 25%, and demonstrate significant improvements in sealing. As far as we know, this is the first paper to report the prevalence of mismatched renal arteries in a large cohort of AAA patients in the real world, while proposing a dedicated device. The breakthrough is to keep the complexity of the repair as close as possible to standard endovascular repair.
RESUMO
PURPOSE: To analyze the learning curve for thoracic endovascular aortic repair (TEVAR) in a single center over a period of 25 years. MATERIALS AND METHODS: In total, 390 consecutive standard TEVAR procedures undertaken between 1996 and 2021 were included in a retrospective, observational, single-center study. Cumulative sum charts were elaborated for the entire center experience (primary outcome) as well as for the first and second implanting physicians. Data on procedural variables (contrast volume, operative and fluoroscopy time), 30-day major adverse events (MAEs) and clinical success, and endoleak and reintervention rates were secondary outcomes and subdivided into 4 quartiles of experience (Q1-Q4) or presented as first 2 versus latest 2 quartiles (Q1-Q2 vs Q3-Q4). RESULTS: The mean follow-up was 4.3±4.0 years. The center's learning curve was achieved after 75 procedures, and it was similar for the first implanting physician. The surgeon coming thereafter had a significantly shorter curve (10 TEVARs). Comparing Q1-Q2 with Q3-Q4, 30-day MAEs (16.1 vs 11.3%, p=0.164), 30-day mortality (11.4% vs 3.6%, p=0.003), and intraoperative additional maneuvers (21.5% vs 13.3%, p=0.033) were reduced along with an improvement in clinical success (85.9% vs 90.3%, p=0.190). From Q1 to Q4, operative time (139.8±65.5 to 76.7±43.7 min, p=0.001), fluoroscopy time (15.1±8.8 to 7.1±5.1 min, p<0.001), and contrast volume (244.0±112.1 to 104.3±46.1 mL, p<0.001) showed a considerable reduction. Late endoleak and aortic-related mortality declined significantly from Q1-Q2 to Q3-Q4 (24.1% to 15.5%, p=0.033 and 18.6% vs 8.2%, p=0.006, respectively). Operative time (p=0.021), contrast volume (p=0.016), and fluoroscopy time (p=0.004) were independent risk factors for endoleak, causing a 1.3-fold risk increase for both each 60 minutes of additional operative time (p=0.021) and every 100 mL of additional contrast medium (p=0.016). Each 10-minute increase in fluoroscopy time determined a 1.4-fold risk increment (p=0.004). CONCLUSION: The learning curve shortened significantly over time with non-negligible clinical outcome improvements, suggesting that specific endovascular training is mandatory to become an effective TEVAR performer. CLINICAL IMPACT: For the first time in literature, the standard TEVAR's learning curve has been evaluated at a single vascular surgery center over a period of 25 years. The learning curve for the center and the first physician historically undertaking TEVAR was achieved at the 75th treated patient. The learning curve of the surgeons coming thereafter was significantly shorter (10 cases). This quarter-century demonstrated that intraoperative learning-related variables were associated with long-term clinical outcomes and all have improved over time. Centers approaching TEVAR for the first time and training program providers could use these data to aim to offer better clinical outcomes.
RESUMO
OBJECTIVE: To assess the real world incidence, outcomes, and risk factors of type III endoleaks (TIIIEL) after endovascular aneurysm repair (EVAR). METHODS: This was a single centre, retrospective, observational, cohort study. All patients with abdominal aortic aneurysms (AAAs) receiving EVAR between 1994 and 2020 were collected prospectively and reviewed. The primary outcome was the cumulative incidence and impact on survival of TIIIELs, either defined as disconnections of modular graft components (TIIIaEL) or fabric defects (TIIIbEL). Secondary outcomes included risk factor analysis evaluating baseline morphological and stent graft details, as well as a comparison of TIIIaEL and TIIIbEL. RESULTS: In total, 2 565 EVARs were performed and 95 (3.7%) TIIIELs were diagnosed at a median interval of 49.5 months (interquartile range [IQR] 19.4, 67.6). Estimated TIIIEL incidence at five years was 6.8%, 2.2%, and 3.6% for first and second generation, third and fourth generation, and fifth and sixth generation, respectively. The survival rate in patients without any high flow endoleak was 88.0%, 67.9%, 56.9%, and 52.1%, while in TIIIEL patients it was 98.6%, 77.2%, 49.8%, and 32.3% at one, five, 10, and 15 years, respectively (p = .77). The distribution of TIIIaEL and TIIIbEL was 70.5% and 29.5%, respectively. TIIIbEL received a higher rate of open treatment (28.6% vs. 7.5%; p = .005) and device or procedure related re-interventions (35.7% vs. 13.4%; p = .013). Fourteen (15.4%) recurrent TIIIELs were diagnosed at a median of 16.8 months (IQR 7.6, 32.1). Old generation endografts (hazard ratio [HR] 2.1, 95% confidence interval [CI] 1.3 - 3.4; p = .002) and non-proprietary extensions (HR 3.6, 95% CI 1.9 - 6.8; p < .001), and angulated and calcified aneurysm neck (HR 3.6, 95% CI 1.2 - 10.6; p = .017) were risk factors for TIIIEL. Every 10 mm maximum AAA diameter increase presented a 1.4 fold higher risk of TIIIEL. CONCLUSION: TIIIEL is a severe condition that is often fatal if left untreated. Old endografts, the implantation of non-proprietary extensions, large AAAs, and angulated and calcified necks are risk factors for TIIIEL that require careful follow up due to the high rate of recurrence.

OBJECTIVE: To investigate the long-term reinterventions of thoracic endovascular repair (TEVAR) after blunt traumatic aortic injury. METHODS: MEDLINE, EMBASE, and Cochrane databases were interrogated until June 2021. Inclusion criteria were blunt traumatic aortic injury treated with TEVAR and mean follow-up of more than 60 months. A systematic review was conducted and data were pooled using a random effects model of proportions applying the Freeman-Tukey transformation. Late reintervention was the primary outcome. Secondary outcomes were procedure-related complications (endoleak, in-stent thrombosis, occlusion, infolding/collapse, bird-beak, migration, and left arm claudication), overall and aortic-related mortality, and aortic diameter changes. RESULTS: Eleven studies with a low quality assessment were included. Four hundred eight patients were collected and the 389 surviving more than 30 days were included. The mean follow-up was 8.2 years (95% confidence interval [CI], 5.7-10.8; I2 = 40.2%). Late reintervention was 2.1% (95% CI, 0.6-3.9; I2 = 0.0%; 11/389 cases) with 0.1% (95% CI, 0.0-1.2; I2 = 0.0%; 3/389) occurring after 5 years. Bird-beak was identified in 38.7% (95% CI, 16.4-63.6; I2 = 86.6%). Left arm claudication occurring after 30 days was 3.1% (95% CI, 0.1-8.6; I2 = 26.9%; 11/140 cases). In-stent thrombosis was 1.9% (95% CI, 0.1-5.2; I2 = 51.8%; 11/389 cases). Endoleak was 0.5% (95% CI, 0.0-1.9; I2 = 0.0%; 5/389 cases). Infolding, occlusion, and migration were reported in 2 of 389, 1 of 389, and 0 of 389 patients, respectively. Overall late survival was 95.6% (95% CI, 88.1-99.8; I2 = 84.7%; 358/389 patients) and only one patient accounted for aortic related mortality. The increase in proximal and distal aortic diameters was estimated at 2.7 mm (95% CI, 1.2-4.3; I2 = 0.0%) and 2.5 mm (95% CI, 1.1-3.9; I2 = 0.0%), respectively. CONCLUSIONS: TEVAR demonstrates remarkably good long-term results and reinterventions are rarely required. Aortic reinterventions tend to occur within the first and after the fifth year.
