Abstract
OBJECTIVE The objective of this study was to assess the primary endpoint defined as the detection of micro-embolic signals (MES) by the use of transcranial Doppler (TCD) in patients with asymptomatic carotid stenosis (≥70%) scheduled for carotid endarterectomy. The secondary endpoint consisted of testing the association of MES with stenosis severity, histopathological, and ultrasound characteristics. METHODS This was a single-center, single-arm, prospective, observational trial. Computed tomography angiography and ultrasound assessment (Geroulakos classification) were mandatory as well as being under best medical therapy. MES number and characteristics were investigated in Holter mode TCD-X device with a standard 1.5 MHz probe. The time points of evaluation were: 24 hours preoperative, 24 hours postoperative, and 30 days postoperative. The histopathological analysis was performed according to the modified American Heart Association classification. One-way analysis of variance tested MES differences over time. Univariable and multivariable logistic regression tested variables potentially associated with MES. RESULTS A total of 120 patients demonstrated a significant reduction of the mean number of MES (3.35 ± 10.04 and 0.82 ± 2.39; pre- and post-carotid endarterectomy, respectively), becoming undetectable at 30 days (P = .001). Hypoechogenic plaques assessed by ultrasound were a significant risk factor for MES (P = .001). The features of plaque vulnerability, such as hemorrhagic component (P = .011), neovascularization (P = .025), signs of inflammation (P = .027), and rupture of the fibrous cap (P = .002) were predictors of MES. Cap rupture was the only predictor in the multivariate analysis (odds ratio, 5.98; P = .030). The stenosis severity was not associated with MES (P = .95) CONCLUSIONS: Patients under best medical therapy had a preoperative embolic activity becoming no more detectable after surgery. Both ultrasound and histologic markers of vulnerability were predictors of MES, and stenosis severity was not associated. TCD gives better insight into the real embolic risk, and future studies should evaluate clinical results coming from its implementation with standard imaging techniques. CLINICALTRIAL gov registration number NCT05134493.

Abstract
BACKGROUND The Najuta stent-graft (Kawasumi Laboratories Inc., Tokyo, Japan) is usually easily advanced to the correct deployment position in the ascending aorta thanks to the pre-curved delivery J-sheath with all fenestrations automatically oriented towards the supra-aortic vessels. Aortic arch anatomy and delivery system stiffness could however represent limitations for proper endograft advancement, especially when the aortic arch bends sharply. The aim of this technical note is to report a series of bail-out procedures that could be useful to overcome the difficulties encountered during the Najuta stent-graft advancement up to the ascending aorta. MAIN BODY The insertion, positioning and deployment of a Najuta stent-graft requires a through-and-through guidewire technique using a .035″ 400 cm hydrophilic nitinol guidewire (Radifocus™ Guidewire M Non-Vascular, Terumo Corporation, Tokyo, Japan) with right brachial and both femoral accesses. When standard maneuver to put the endograft tip into the aortic arch, some bail-out procedures can be applied to obtain proper positioning. Five techniques are described into the text: positioning of a coaxial extra-stiff guidewire; positioning of a long introducer sheath down to the aortic root from the right brachial access; inflation of a balloon inside the ostia of the supra-aortic vessels; inflation of a balloon inside the aortic arch (coaxial to the device); and transapical access technique. This is a troubleshooting guide for allowing physicians to overcome various difficulties with the Najuta endograft as well as for other similar devices. SHORT CONCLUSION Technical issues in advancing the delivery system of Najuta stent-graft could occur. Therefore, the rescue procedures described in this technical note could be useful to guarantee the correct positioning and deployment of the stent-graft.

Abstract
BACKGROUND Endovascular repair of aortic arch lesions requires revascularization of epiaortic vessels in case of coverage. The objective of this study was to compare the outcomes of surgical bypass versus endovascular reconstruction with a chimney graft. METHODS A retrospective analysis of a multicenter register between January 2005 and December 2019 was performed. A total of 127 patients were included and divided into 2 groups: thoracic endovascular aortic repair + surgical debranching (n = 72) and thoracic endovascular aortic repair + chimney stenting (n = 55). The main end points were major neurologic sequelae and type IA endoleak. Propensity score matching was performed to analyse baseline variables related to these outcomes. RESULTS The mean follow-up was 35.6 months for the debranching group and 34.1 for the chimney group (P = 0.65). The incidence of stroke was higher in the chimney group although not statistically significant (7.3% vs. 4.1%; P = 0.46); for both groups, a wide angle between the ostium of the target vessel and the aorta and landing in Ishimaru Zone 0 was found to be the main predictors for major neurologic sequelae (P = 0.002 and P = 0.003, respectively). During follow-up, 9 (12.5%) type IA endoleaks occurred in the debranching group and 12 (21.8%) in the chimney group (P = 0.14). Aortic diameter larger than 66 mm and arch angle >46° had a strong association with proximal endoleak incidence (P = 0.001 and P = 0.011, respectively) CONCLUSIONS: Surgical debranching showed better results than chimney stenting in terms of major neurologic events incidence and type IA endoleak, although the difference between the groups was not statistically significant. Further research with larger cohorts is needed to establish the indications for these procedures.

Abstract
INTRODUCTION To compare endoleak outcomes after thoracic endovascular aneurysm repair (TEVAR) with different stent-graft generations into long-term follow-up. DESIGN retrospective, observational, and single-center cohort study. METHODS TEVAR procedures performed between November 1995 and December 2020 were analyzed. The primary endpoint of this study was the freedom from endoleak (type I/III) in four stent-graft generations during the follow-up period. The first generation (GEN1) included: Vanguard; AneuRx and Talent; Stentor; Excluder; Endologix; EndoFit. The second generation (GEN2) included: TAG and TX. The third (GEN3) included: Relay Plus; Valiant Captivia; Zenith Alpha and custom-made. The fourth (GEN4) included: Relay Pro; Conformable C-TAG; Navion; E-Vita; Najuta; Nexus; standard and custom-made thoraco-abdominal devices. Nonaortic and aorta-related survival was considered as secondary outcome. RESULTS A total of 509 TEVAR were included with a 44.3 ± 42.5 months mean follow-up. Freedom from endoleak at 5 years was 65.6%, 61.4%, 76.2%, and 69.1% for GEN1, GEN2, GEN3, and GEN4, respectively (p = 0.368). The first two generations demonstrated a higher endoleak rate when compared with the two most recent ones (27.2 vs 18.2%, respectively; p = 0.043). GEN1 was an independent risk factor (p = 0.014) and GEN4 was an independent protective factor (p = 0.001) for endoleak. GEN1 was found to be a risk factor for type-Ia endoleak (p = 0.059). GEN4 demonstrated a protective association regarding type-Ib endoleak (p = 0.012). Overall survival was 75.3%, 44.4%, 27.2%, and 17.6% at 1, 5, 10, and 15 years, respectively. Survival distinguished as non-related versus aortic-related was 86.7% vs 23.5%, 52.7% vs 9.8%, 32.9% vs 2.0%, 21.2% vs 0% at 1, 5, 10, and 15 years, respectively (p< 0.000). CONCLUSION Endoleak occurred in a non-negligible percentage of TEVAR patients. A significant reduction of endoleak incidence over evolving stent-grafts generations was registered. Newer stent-graft generations demonstrated better long-term endoleak. Data about long-term outcomes require ongoing updates to prove both the reliability and the durability of newer stent-graft generations.

Abstract
BACKGROUND The diabetic foot ulcer (DFU) is a high prevalence complication that significantly impairs the health-related quality of life (HRQoL) and is characterized by prolonged hospital length of stay (LOS). The impact of the micro-fragmented autologous adipose tissue injection at the minor amputation wound in the case of DFU (MiFrAADiF) on HRQoL and LOS compared to the standard care has not been determined yet. METHODS This was a two-arm, 6-month, individually randomized controlled single-center clinical trial. A 1:1 randomization to local injection of autologous micro-fragmented adipose tissue (treatment group; n=57) or standard clinical care (control group; n=57) was performed. The primary objective was the HRQoL. The secondary endpoint was the LOS. HRQoL was assessed with the Medical Outcomes Study 36-item Short-Form Health Survey which provides 2 scores focused on physical (PCS) and mental functioning (MCS). The trial was registered in ClinicalTrials.gov (NCT03276312). RESULTS The type of treatment (p=0.009) and the time elapsed since surgery (p= 0.0000) demonstrated a significant improvement on PCS. The MCS improvements resulted in a non-significant association with treatment (p= 0.21). The time elapsed since surgery showed a significant influence on the MCS (p= 0.0000). The mean LOS was 16.2 days and 24.4 days for the treatment and the control group respectively (p= 0.025). CONCLUSIONS The MiFrAADiF trial demonstrated a significant improvement in terms of physical HRQoL and a significant reduction of the hospital length of stay after injection of micro-fragmented autologous adipose tissue in diabetic patients' minor amputations wound.

Abstract
OBJECTIVE The introduction of new endograft models improved long-term results of abdominal aortic aneurysm (AAA) endovascular repair (EVAR), but most of them maintained an old and unchanged design: a short body and long legs shifting up the flow divider. This study assessed the long-term results of EVAR with unimodular endoprosthesis fixed at the aorto-iliac bifurcation (Anatomical FiXation), in a large, unselected cohort. MATERIALS AND METHODS In a single-center, retrospective cohort study, 623 patients selectively treated between 1999 and 2016, were analyzed. Follow-up protocol included at least a computed tomography angiography within 3 months and a duplex ultrasound and clinical exam yearly. All enrolled patients were analyzed by 2020. The primary outcomes were technical success, clinical success, and survival. Secondary outcomes included survival-free from late-open-conversion (LOC), reintervention, and endoleaks. RESULTS Median age was 74±11 years and the follow-up 93±54 months. The technical success was achieved in 99.4% and the 30-day clinical success was 98.4%. A 5-year clinical success of 97.7% was registered and at 10 years success was 96.7%. The overall survival at 1, 5, 10, and 15 years was 92.4%, 79.5%, 64.9%, and 45.5%, respectively. Six (0.98%) AAA-related death were registered, 3 caused by infection of the endograft and 3 for secondary rupture. LOCs were 9 (1.47%) and reintervention-free survival at 1, 5, 10, and 15 years were 88.4%, 78.0%, 76.2%, and 74.6%, respectively. Freedom from endoleaks was 88.8% at 1 year and 72.7% at 15 years. A total of 63 high-flow endoleaks were registered (43 type I, 7 type IIIa, 12 type IIIb, and 1 type Ib+IIIb). No migrations were recorded, and the graft limb thrombosis rate was 1.14%. From a multivariate analysis resulted that long-term clinical success appeared to be reduced in patients affected by diabetes [odds ratio (OR) 0.24; p=0.04] and in presence of calcified and thrombotic iliac accesses (OR 0.16; p=0.006). CONCLUSION EVAR with the Anatomical FiXation was confirmed to be safe, feasible, and effective to prevent AAA rupture in the long term as well. However, the overall survival remains afflicted by cardiovascular accident. The original concept of unibody bifurcated design allowed a very low rate of graft thrombosis and zeroed the risk of migration and related reintervention.

Abstract
A 58-year-old man with a history of aortic and mitral mechanical valve replacement was referred to our hospital for symptomatic chronic heart failure. In 1988, he had undergone open surgical correction of an isthmic aortic coarctation (CoA), with the creation of an extra-anatomic bypass from the left subclavian artery to the descending thoracic aorta. The following findings were found: severe mitral valve failure with perivalvular leakage, severe aortic valve stenosis, pulmonary hypertension, distal anastomotic aneurysm with the apparent occlusion of the CoA. A thoracic endovascular aneurysm repair was performed. A postoperative high-pressure leak with no evident signs of ineffective sealing was observed. Computed tomography angiography (CTA) 3D reconstruction demonstrated the recanalization of the CoA. A second procedure was planned. The CoA was anterogradely cannulated. Three coils were deployed into the aneurysmal sac, followed by a vascular plug, positioned on the coarctation conduit, but it failed to anchor and dislocated into the sac. A second plug was deployed, but it also partially dislocated. Finally, a patent foramen ovale occluder device was deployed to occlude the communication. The final angiogram showed the complete occlusion of the coarctation and correction of the leak, which was confirmed by a 6-month post-operative CTA.

Abstract
PURPOSE To evaluate the efficacy of endovascular repair of popliteal artery aneurysms (PAAs) with a wire-interwoven nitinol stent. MATERIALS AND METHODS This is a prospective, descriptive, and analytical study. From January 2016 to December 2018, 28 consecutive patients (29 lower limbs) were treated for a PAA with the deployment of the Supera stent (Abbott Vascular, Illinois). Twenty-three (79.3%) PAAs were asymptomatic; 6 (20.7%) presented with symptoms. The mean diameter and length of the aneurysm were 26.8 mm (20-40 mm) and 47.1 mm (23-145 mm) respectively. The primary endpoint was the prevention of embolic symptoms. The secondary endpoints were aneurysm exclusion, aneurysm diameter decrease, freedom from reintervention, and preservation of preoperative runoff vessels. RESULTS Technical success was 100%, with a median of 2.4 run-off vessels at completion angiography, without any loss of run-off vessels. A double Supera stent was deployed in 10 cases. At completion angiography, a median of 2.4 runoff vessels were present, without any loss of runoff vessels. The mean follow-up time was 24.3 (12-35) months. Primary endpoints were reached in 100% of the cases and vessels run off was preserved in all cases. In 2 PAAs, complete sac thrombosis was witnessed at 6-month follow-up, while at 12-month follow-up, it was seen in 10 of 29 (34.4%) limbs. In all the other cases the diameter of the aneurysm remained stable, with a freedom from sac enlargement of 100%. No fractures or stent thromboses were detected. CONCLUSIONS For endovascular repair of PAAs, the use of a thick interwoven-wire stent, that could work like a multilayer flow modulator showed encouraging mid-term results with no cases of stent fracture, occlusion or aneurysm increase.

Abstract
Background The diabetic foot ulcer (DFU) is one of the most prevalent complications of diabetes mellitus and often develops severe effects that can lead to amputation. A non-healing “minor” amputation often precedes a major amputation resulting in a negative impact on the function and quality of life of the patients. Stem cell-based therapies have emerged as a promising option to improve healing, and the adipose tissue is an abundant and easy to access source. The injection of autologous micro-fragmented adipose tissue at the amputation stump of a diabetic population undergoing a lower limb minor amputation was evaluated and compared with the standard care. Methods In this randomized controlled trial with two arms (parallel assignment) and no masking, 114 patients undergoing a lower limb minor amputation were randomized to standard of care or to micro-fragmented adipose tissue injection prepared using a minimal manipulation technique (Lipogems®) in a closed system. Clinical outcomes were determined monthly up to 6 months. Primary endpoint of the study was the evaluation of the healing rate and time after the minor amputation. Secondary endpoints included the assessment of safety, feasibility, technical success, relapse rate, skin tropism, and intensity of pain. Results At 6 months, 80% of the micro-fragmented adipose tissue-treated feet healed and 20% failed as compared with the control group where 46% healed and 54% failed (p = 0.0064). No treatment-related adverse events nor relapses were documented, and technical success was achieved in all cases. The skin tropism was improved in the treatment group, and the pain scale did not differ between the two groups. Conclusion The results of this randomized controlled trial suggest that the local injection of autologous micro-fragmented adipose tissue is a safe and valid therapeutic option able to improve healing rate following minor amputations of irreversible DFU. The technique overcomes several stem cell therapy-related criticisms and its potential in wound care should be better evaluated and the therapeutic indications could be expanded. Trial registration ClinicalTrials.gov number: NCT03276312. Date of registration: September 8, 2017 (retrospectively registered).

Abstract
OBJECTIVE To cross-validate a biopsychosocial model using physical disability, helplessness and passive coping to predict depression and pain in rheumatoid arthritis (RA). METHODS Clinical and psychological measures were collected from 157 RA patients at three time points over a period of 12 months. Path analysis was used for cross-sectional and longitudinal prediction of depression and pain. RESULTS Helplessness and passive coping were found to be significant mediators of the relationship between the physical disability and future depression and pain. Cross-sectionally, the predictive model could account for 52-94% of the variance of pain and 37-71% of the variance of depression. Longitudinally, the predictive model could explain 29-43% of the variance of pain and 21-33% of the variance of depression. CONCLUSIONS These results suggest that physical disability, helplessness and passive coping have a significant impact on the levels of pain and depression experienced by RA patients.

Abstract
OBJECTIVE To determine the ability of coping to predict pain. METHODS Data on 111 rheumatoid arthritis (RA) patients (86 women and 25 men) were gathered from a mail survey. Statistical analyses were conducted on a range of clinical and psychological variables: physical disability, disease duration, pain, depression, helplessness, and passive and active coping. Pain was measured with both the pain subscale of the Arthritis Impact Measurement Scales and a visual analogue scale, and coping was measured with the Vanderbilt Pain Management Inventory. RESULTS A series of multiple regression analyses revealed that the optimal predictors of pain in RA were physical disability and passive coping, which accounted for 40% of the variance associated with pain. Path analysis revealed that passive coping mediates between the physical disability and pain, and between physical disability and depression. CONCLUSION The results of this study have implications for the overall management of RA. In addition to the medical treatment, the experience of pain and depression in RA should be addressed through an intervention programme designed to enhance coping strategies.
