ABSTRACT
BACKGROUND: Sclerotherapy is a cornerstone of the treatment of chronic venous disease, despite some technical aspects (e.g., sclerosant liquid agent concentration [SLAC] and contact time between sclerosant agent and vein wall [ctSA/VW]) to maximize outcomes remain an unsolved problem and a source of debate. An innovative three-balloon catheter has been developed to allow sclerotherapy in empty vein conditions (Empty Vein Ablation technique, EVA), revolutionizing the definition of SLAC and ctSA/VW. Aim of this experimental study is to analyze EVA effects on intima and media vessel tunicae using different SLAC and ctSA/VW in an in-vivo animal model. METHODS: Two adult sheep were treated by EVA using jugular and common iliac vein axes (eight vein segments). Different SLAC (polidocanol 0.5% or 1%) and different ctSA/VW (3 or 5 minutes) were combined for testing residual circumferential intima percentage and media thickness after EVA. RESULTS: Intact circumferential residual intima after the treatment was 21.3±4.9%, 18.2±7.4%, 15.7±2.4% and 8.9±2.0% using 0.5% (3 min), 0.5% (5 min), 1% (3 min) and 1% (5 min), respectively (R2=0.945; control sample: 97.6%). Media thickness after the treatment was 121.6±35.3 µm, 110.9±7.8 µm, 96.1±30.4 µm and 79.1±34.1 µm using 0.5% (3 min), 0.5% (5 min), 1% (3 min) and 1% (5 min), respectively (R2=0.990; control sample 125.7 µm). No significant modifications were detected analyzing the adventitia in all samples. CONCLUSIONS: EVA proved to be effective in venous wall destruction even with a very low SLAC and ctSA/VW (0.5% in 3 minutes), in quite large caliber veins. Direct comparisons with foam/liquid sclerotherapy should be done to confirm therapeutic effectiveness of these results, despite EVA has provided a maximized and controlled SA/VW contact time and ratio.

Pediatric major arterial vascular injuries may belong to the same principal categories as adults, but have been poorly documented, with an estimated overall incidence of <2% of all vascular traumas. Open surgery has been the mainstay of treatment, but no clear guidelines have been developed to recommend the best practice patterns in terms of strategy or repair as well as postoperative pharmacological regimen. Herein, we report three cases and a narrative review of the available literature regarding the main aspects when dealing with pediatric arterial injuries based on the predominant series available from the most recent published literature.
ABSTRACT
INTRODUCTION: Favorable midterm outcomes have been reported with the use of low-profile endografts (LPE), but long-term data is still needed. Furthermore, it is unclear if each of these LPE may have advantages over the other, which may, in turn, affect the outcomes. We systematically reviewed the literature about complications and reintervention rates of patients submitted to endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm (AAA) using LPE. MATHERIALS AND METHODS: A literature search was conducted including articles that reported 30-days and follow-up mortality, complications, and reintervention rates of patients treated with EVAR using Incraft (Cordis), Zenith LP/Alpha (Cook Medical Inc) and Ovation (Endologix) endografts. RESULTS: 36 papers were evaluated, reporting results of 582 patients treated with Zenith device, 1211 with Incraft and 3449 with Ovation. During follow up, similar survival and freedom from reintervention rates were reported among the various types of endograft both at 1 and 3 years. The incidence of limb stenosis/kinking was significantly higher in patients treated with Zenith LP/Alpha (2.1%, P = 0.008), while the Incraft device had a significantly lower proportion of type III endoleaks (P < 0.001). CONCLUSIONS: Long-term survival and freedom from reintervention rates were comparable among the three LPEs. The Cook Zenith device had the highest rates of limb stenosis/kinking, while the Incraft device had the lowest occurrence of type III endoleak. PROSPERO: Registration number: CRD42022315875.

We aimed to explore the feasibility of 4D flow magnetic resonance imaging (MRI) for patients undergoing thoracic aorta endovascular repair (TEVAR). We retrospectively evaluated ten patients (two female), with a mean (±standard deviation) age of 61 ± 20 years, undergoing MRI for a follow-up after TEVAR. All 4D flow examinations were performed using a 1.5-T system (MAGNETOM Aera, Siemens Healthcare, Erlangen, Germany). In addition to the standard examination protocol, a 4D flow-sensitive 3D spatial-encoding, time-resolved, phase-contrast prototype sequence was acquired. Among our cases, flow evaluation was feasible in all patients, although we observed some artifacts in 3 out of 10 patients. Three individuals displayed a reduced signal within the vessel lumen where the endograft was placed, while others presented with turbulent or increased flow. An aortic endograft did not necessarily hinder the visualization of blood flow through 4D flow sequences, although the graft could generate flow artifacts in some cases. A 4D Flow MRI may represent the ideal tool to follow up on both healthy subjects deemed to be at an increased risk based on their anatomical characteristics or patients submitted to TEVAR for whom a surveillance protocol with computed tomography angiography would be cumbersome and unjustified.
ABSTRACT
AIM: We present a case of successful endovascular repair of late ruptured aortic anastomotic pseudoaneurysm following previous left subclavian artery-descending thoracic aorta bypass and concomitant emergency thoracic endovascular aortic repair (TEVAR) of complicated endovascular aortic de-coarctation never previously described is also presented. A review of the intraoperative, 30-day, and follow-up morbidity, mortality, and complications of TEVAR as endovascular treatment of late aneurysm/pseudoaneurysms after surgical aortic de-coarctation was also performed. METHODS: The systematic review was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement and following PICO model. A literature search was conducted on MEDLINE, PubMed, EMBASE, Cochrane Library, Google Scholar, Science Direct, and Web of Science using the words "tevar of late complication of aortic coarctation surgical repair" and "endovascular repair of anastomotic pseudoaneurysm in coarctation" up to June 17, 2022. Data were extracted from study documents about study design, patient's demographics and comorbidities, details about primary surgical repair, type of late complication, time between open surgery and occurrence of complications, details of the secondary endovascular procedure with technical success, early, and follow-up mortality and morbidity. RESULTS: A total of 18 papers were included with 78 patients (48 men, 69.5%). The most frequent type of primary open surgical repair was patch aortoplasty (46, 58.9%). Focusing on aneurysm and pseudoaneurysm as late complications, most of the patients were asymptomatic (45, 57.7%). All patients underwent TEVAR, 14 of them (17.9%) in urgent/emergent setting. The technical success was 98.7%, with 1 intraoperative death due to rupture of the aorta. In total, 31 patients out of 78 (39.7%) showed different complications in the immediate postoperative time, with type II endoleak being the most observed (8/31, 25.8%). The mean follow-up time was about 2 years (26.5 months, range 3-92). Overall, 30-day mortality was 2.6%. Complications occurred in 30 patients (39.4%), 23 of them resolved during the follow-up period. CONCLUSIONS: With the limit of low-quality data, TEVAR can be considered a safe and effective option for the treatment of late complications after open surgery for aortic coarctation, even in urgent settings. CLINICAL IMPACT: Different specialists have to face the technical complexities and risks related to treatment of late complications after surgical de-coartaction, which can be either surgical or endovascular, and depend on patient's ages. Although covered stents appear to have some protection from the development of stent fractures, doesn't provide complete protection from late aneurysm formation. In this setting, TEVAR may represent a valuable option, combining the advantages of the covered stent with those of a device that can cover a wider range of aortic length, especially in adult patients. This study shows thoracic endovascular repair can be considered a safe and effective option in clincal practice for the treatment of late complications after open surgery for AC, even in urgent settings.
ABSTRACT
BACKGROUND: Penetrating vascular injuries (PVIs) of the lower limbs due to stab wounds are associated with high mortality and limb loss rates. We analyzed the outcomes of a series of patients who underwent surgical treatment of these lesions, assessing the presence of any factor associated with limb loss and mortality; (2) Methods: Data of patients admitted from 01/2008 to 12/2018 were retrospectively analyzed. Primary outcomes were the limb loss and the mortality rate at 30 days postoperatively. Univariate and multivariate analyses were performed as appropriate. p values < 0.05 were considered significant; (3) Results: Data of 67 male patients were analyzed. Two died (3%) and three (4.5%) had a lower limb amputation after failed revascularization. In the univariate analysis, the clinical presentation significantly affected the risk of postoperative mortality and limb loss. The location of the lesion at the superficial femoral artery (OR 4.32, p = 0.001) or at the popliteal artery (OR 4.89, p = 0.0015) also increased the risk. In the multivariate analysis, the need for a vein graft bypass was the only significant predictor of limb loss and mortality (OR 4.58, p < 0.0001); (4) Conclusions: PVIs of lower limbs due to stab wounds were lethal in 3% of cases and lead to a secondary major amputation in 4.5% more cases. The need for a vein bypass grafting was the strongest predictor of postoperative limb loss and mortality.
ABSTRACT
Blunt thoracic aortic injury (BTAI) is a potentially fatal condition that needs prompt recognition and expedited management. Clinical manifestations of BTAI are not straight forwarding and may be misdiagnosed. The grade of aortic injury is an important determinant of perioperative mortality and morbidity, as well as the indication of treatment, along with the presence of concomitant lesions of other involved organs. The mainstay of treatment nowadays for hemodynamically stable patients who survive the trauma scene is represented by delayed endovascular repair whenever anatomically and clinically feasible. Endovascular repair, in fact, is burdened by lower perioperative mortality and morbidity rates if compared to open surgical repair, but concerns remain about the need for long-term surveillance and radiation exposure in patients who are at a younger age than patients treated for the aneurysmal disease. The aim of the paper is to provide an update on the diagnostic modalities and strategies of treatment for patients affected by BTAI.
ABSTRACT
INTRODUCTION: The aim of this study was to perform a systematic review about the clinical and technical aspects of late open conversion for failed endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAA), and to investigate if the need for suprarenal aortic cross clamping, graft infection, urgent procedures, endoleaks and aortic rupture were associated with an increase of 30-days (perioperative) mortality. EVIDENCE ACQUISITION: A literature search was conducted on PubMed using the words "open conversion endovascular" on December 29th, 2021. Studies included randomized controlled trials, cohort studies, and case series of patients submitted to open conversion that were performed at least 1 month after the initial EVAR for AAA, reporting about 30-days mortality after surgery. A meta-analysis was performed to explore the association of suprarenal aortic cross clamping, graft infection, urgent procedures, endoleaks and aortic rupture with 30-days postoperative mortality using log odds ratios (ORs), with STATA/MP 17.0 (Stata Corp. 2021, LLC). Two-sided P values less than 0.05 were considered statistically significant. EVIDENCE SYNTHESIS: The search retrieved 985 results on PubMed from 1994 to 2021. Among them, 40 papers were included in the study for the systematic review, and 5 of them for the meta-analysis. A total of 2297 patients from 1992 to 2020 were submitted to open conversion after a median of 40.4 months from the initial EVAR. Endoleak was the most frequent cause of open conversion (76.3%). Perioperative mortality was 23.5% for urgent and 5.3% for elective conversions. At meta-analysis, urgent procedures and aortic rupture were both associated with higher perioperative mortality (OR 5.27, 95% CI 2.90-9.57 and OR 5.61, 95% CI 3.09-10.19 respectively). Similarly, patients with infections and who needed suprarenal aortic clamping were at higher risk of 30-days postoperative death (OR 3.74, 95% CI 1.96-7.13) and OR 2.23, 95% CI 1.24-4.02), while the presence of a preoperative endoleaks was not associated with a higher 30-days mortality. CONCLUSIONS: Late open conversion after EVAR of AAA is burdened by a perioperative mortality rate of 23.5% for urgent and 5.3% for elective cases. Urgent treatment, presence of aortic rupture or infection, and the need for suprarenal aortic cross clamping were associated with increased perioperative mortality, while the presence of an endoleak did not affect perioperative mortality.

BACKGROUND: To compare the outcomes of patients who were submitted to partial carotid endarterectomy (P-CEA) to those of patients who underwent standard conventional CEA with patch closure (C-CEA) and eversion CEA (E-CEA) for a significant carotid stenosis. METHODS: Data of patients who consecutively underwent CEA from January 2014 to December 2018 for a significant carotid stenosis were retrospectively collected. Primary outcomes included mortality and the occurrence of neurologic and cardiologic complications, both at 30 days and during follow-up. Secondary outcomes included the occurrence of perioperative local complications (i.e. cranial nerve injuries, hematomas) and restenosis during follow-up. P values < 0.5 were considered statistically significant. RESULTS: Three-hundred twenty-seven patients (241 males, 74%) underwent CEA for carotid stenosis (28.6% symptomatic). P-CEA was performed in 202 patients (61.8%), while C-CEA and E-CEA were performed in 103 and 22 cases respectively. At 30 days, neurologic complications were not significantly different among the 3 groups (2.8% in the group of C-CEA, 2.4% after P-CEA and 0% in E-CEA patients, P = 0.81), neither during follow-up. Perioperative local complications also were not significantly different among the 3 groups (P = 0.16). CONCLUSIONS: P-CEA had similar outcomes if compared to C-CEA and to E-CEA in terms of perioperative mortality, occurrence of neurologic and cardiologic complications, and occurrence of local complications. Also, in the long-term, P-CEA, C-CEA, and E-CEA were burdened by similar rates of mortality, neurologic, and cardiologic complications and restenosis.

We aimed at evaluating the ability of point shear-wave elastography (pSWE) and of a radiofrequency (RF) echo-tracking-based method in preoperatively assessing the vulnerability of the carotid plaque in patients undergoing carotid endarterectomy (CEA) for significant asymptomatic stenosis. All patients who underwent CEA from 03/2021 to 03/2022 performed a preoperative pSWE and an RF echo-based wall evaluation of arterial stiffness using an Esaote MyLab ultrasound system (EsaoteTM, Genova, Italy) with dedicated software. The data derived from these evaluations (Young's modulus (YM), augmentation index (AIx), pulse-wave velocity (PWV)) were correlated with the outcome of the analysis of the plaque removed during the surgery. Data were analyzed on 63 patients (33 vulnerable and 30 stable plaques). In stable plaques, YM was significantly higher than in vulnerable plaques (49.6 + 8.1 kPa vs. 24.6 + 4.3 kPa, p = 0.009). AIx also tended to be slightly higher in stable plaques, even if it was not statistically significant (10.4 + 0.9% vs. 7.7 + 0.9%, p = 0.16). The PWV was similar (12.2 + 0.9 m/s for stable plaques vs. 10.6 + 0.5 m/s for vulnerable plaques, p = 0.16). For YM, values >34 kPa had a sensitivity of 50% and a specificity of 73.3% in predicting plaque nonvulnerability (area under the curve = 0.66). Preoperative measurement of YM by means of pSWE could be a noninvasive and easily applicable tool for assessing the preoperative risk of plaque vulnerability in asymptomatic patients who are candidates for CEA.
ABSTRACT
BACKGROUNDS: Resistance to the pharmacological effect of clopidogrel in patients undergoing dual antiplatelet therapy for carotid stenting may increase the risk of periprocedural neurological events. The purpose of the study was to describe the phenomenon of clopidogrel resistance in a series of patients undergoing carotid stenting. METHODS: Data of patients who consecutively underwent carotid stenting from November 2016 to December 2020 for a significant stenosis and who underwent a dual antiplatelet therapy using acetyl-salicylic acid and clopidogrel were prospectively collected. Patients who were already taking a different thienopyridine were excluded. The effectiveness of antiplatelet drugs was assessed by the impedance aggregometry test. Primary endpoint was to evaluate the incidence of clopidogrel resistance and the effectiveness of ticagrelor as alternative therapy. P values < 0.05 were considered statistically significant. RESULTS: Two-hundred patients (80 females, 40%) underwent stenting for carotid stenosis (94% asymptomatic). The phenomenon of clopidogrel resistance was observed in 38 patients (19%), in whom clopidogrel was replaced by ticagrelor (90 mg/bis in die) with 100% effectiveness at aggregometry test. Platelet counts was associated to clopidogrel resistance (P = 0.001). There was no stent thrombosis at 30 days, neither major hemorrhagic events; a total of 12/200 major adverse cardiovascular events occurred (6%), including 1 in the group of patients who took ticagrelor and 11 in group of patients under clopidogrel (2.6% versus 6.7%, P = 0.55). CONCLUSIONS: Clopidogrel was ineffective in 19% of patients undergoing carotid stenting. Platelet count seemed to affect this phenomenon. In these patients, clopidogrel was effectively replaced by ticagrelor.

PURPOSE: To present stent-graft treatment of floating thrombus in the abdominal aorta. A review of the literature about aortic floating thrombus (AFT) was also performed. CASE REPORT: A 56-year-old female with no risk factors for vascular disease but with history of a mild COVID-19 infection in the previous month, for which she had started anticoagulant therapy at a prophylactic dosage, developed an acute ischemia of the lower limbs and was diagnosed with floating thrombosis of the abdominal aorta. The thrombus was excluded from the aortic blood flow by deployment of a stent-graft in the abdominal aorta. At 12 months, the patient was well, and the thrombus in the abdominal aorta appears to be completely excluded by the stent-graft. A review of the available literature from 1980 to 2022 showed 74 cases of AFT located in the aortic arch, in the descending thoracic and in the abdominal aorta. In most cases the AFT involved the aortic arch (38/74, 51.3%) and/or the descending thoracic aorta (30/74, 40.5%), while the abdominal aorta was involved in 6 cases. In 2 of these 6 cases, the patients had a COVID-19 infection. The AFT was mostly approached either medically with anticoagulation/systemic thrombolysis (32/74, 43.2%) or with surgical removal (31/74, 41.9%), while endovascular coverage of the thrombus with an endograft was performed in 6 cases of AFT located in the aortic arch and in the descending thoracic aorta (3 cases each). CONCLUSION: There is no consensus about the optimal treatment of AFT. In selected cases, abdominal stent-grafts may be used for stabilization and exclusion of symptomatic abdominal aorta floating thrombosis to prevent progression and recurrent embolization.

Redox imbalance of the endothelial cells (ECs) plays a causative role in a variety of cardiovascular diseases. In order to better understand the molecular mechanisms of the endothelial response to oxidative stress, the involvement of circular RNAs (circRNAs) was investigated. CircRNAs are RNA species generated by a "back-splicing" event, which is the covalent linking of the 3'- and 5'-ends of exons. Bioinformatics analysis of the transcriptomic landscape of human ECs exposed to H2O2 allowed us to identify a subset of highly expressed circRNAs compared to their linear RNA counterparts, suggesting a potential biological relevance. Specifically, circular Ankyrin Repeat Domain 12 (circANKRD12), derived from the junction of exon 2 and exon 8 of the ANKRD12 gene (hsa_circ_0000826), was significantly induced in H2O2-treated ECs. Conversely, the linear RNA isoform of ANKRD12 was not modulated. An increased circular-to-linear ratio of ANKRD12 was also observed in cultured ECs exposed to hypoxia and in skeletal muscle biopsies of patients affected by critical limb ischemia (CLI), two conditions associated with redox imbalance and oxidative stress. The functional relevance of circANKRD12 was shown by the inhibition of EC formation of capillary-like structures upon silencing of the circular but not of the linear isoform of ANKRD12. Bioinformatics analysis of the circANKRD12-miRNA-mRNA regulatory network in H2O2-treated ECs identified the enrichment of the p53 and Foxo signaling pathways, both crucial in the cellular response to redox imbalance. In keeping with the antiproliferative action of the p53 pathway, circANKRD12 silencing inhibited EC proliferation. In conclusion, this study indicates circANKRD12 as an important player in ECs exposed to oxidative stress.

Sarcopenia has been associated with an increased incidence of adverse outcomes, including higher mortality, after endovascular aortic repair (EVAR). We aim to use computed tomography (CT) to quantify changes in total psoas muscles area (PMA) and psoas muscle density (PMD) after EVAR, and to evaluate the reproducibility of both measurements. PMA and PMD were assessed via manual segmentation of the psoas muscle on pre- and post-operative CT scans belonging to consecutive patients who underwent EVAR. Wilcoxon test was used to compare PMA and PMD before and after EVAR, and inter- and intra-reader agreements of both methods were evaluated through Bland−Altman analysis. A total of 50 patients, 42 of them males (84%), were included in the study. PMA changes from 1243 mm2 (1006−1445 mm2) to 1102 mm2 (IQR 937−1331 mm2), after EVAR (p < 0.001). PMD did not vary between pre-EVAR (33 HU, IQR 26.5−38.7 HU) and post-EVAR (32 HU, IQR 26−37 HU, p = 0.630). At inter-reader Bland−Altman analysis, PMA showed a bias of 64.0 mm2 and a coefficient of repeatability (CoR) of 359.2 mm2, whereas PMD showed a bias of −2.43 HU and a CoR of 6.19 HU. At intra-reader Bland−Altman analysis, PMA showed a bias of −81.1 mm2 and a CoR of 394.6 mm2, whereas PMD showed a bias of 1.41 HU and a CoR of 6.36 HU. In conclusion, PMA decreases after EVAR. A good intra and inter-reader reproducibility was observed for both PMA and PMD. We thus propose to use PMA during the follow-up of patients who underwent EVAR to monitor muscle depletion after surgery.

Endovascular techniques have progressively become the first option for the treatment of stenosis and occlusions of both aorto-iliac and femoro-popliteal district. The development of new technologies and new materials has broadened the applicability of the endovascular techniques, allowing the treatment of each lesion with the most suitable material. A knowledge of the behavior of endovascular materials when treating peripheral arterial disease (PAD) is, therefore, crucial for optimization of the results. Here, we aim to review the most important technical features of the actually available endovascular materials for treating PAD.
ABSTRACT
Although exostosis or osteochondroma is a common bone tumor, associated vascular complications are rare. Clinical and radiological diagnoses are sometimes challenging, and there is no codification for surgical management. We report two cases of popliteal arterial pseudoaneurysms due to osteochondroma of the distal femur. A review of the current literature about case series and case reports of patients affected by arterial pseudoaneurysm complicating osteochondroma was also performed.
ABSTRACT
AIM: To assess the effect of antegrade and retrograde common iliac artery (CIA) revascularization on erectile dysfunction (ED) using the validated International Index of Erectile Function (IIEF) questionnaire, on patients treated for chronic occlusions of the CIA. MATERIALS AND METHODS: Clinical data of patients who were submitted either to endovascular CIA revascularization (group A) or to femoral-femoral crossover bypass (group B) due a unilateral total occlusion of the CIA between 01/2015 and 12/2019 were retrospectively analyzed. Primary outcomes included the evaluation of ED using the IIEF questionnaire, before and 30 days after the operation. A P value <0.05 was considered statistically significant. RESULTS: A total of 33 patients underwent endovascular (14 patients, group A) or surgical treatment (19, group B) Before the operation, no differences were recorded in the occurrence of ED between the two groups, neither in the results of the IIEF questionnaire. After the intervention, patients of group A performed significantly better than those of group B in terms of IIEF questionnaire (18 ± 10.1 versus 12.1 ± 14.8, P=0.01). Age and COPD were negatively correlated with the preoperative results of the IIEF questionnaire (OR 0.049, 95%CI 0.02-0.05, P<0.001 and OR 0.29, 95%CI 0.01-0.56, P=0.03, respectively) and the postoperative results of the IIEF questionnaire (OR 0.02, 95% CI 0.01-0.04, P<0.001, and OR 0.46, 95% CI 0.17-0.75, P=0.001, respectively). CONCLUSIONS: Patients who were submitted to endovascular antegrade revascularization for occlusion of the CIA performed significantly better in terms of IIEF questionnaire than those who underwent surgical femoral-femoral crossover bypass and therefore retrograde HA revascularization.
