Abstract Background: Standard balloon-catheter thromboembolectomy (TE) is an established effective treatment for acute lowerlimb ischemia (ALI) with recognized limitations when there is an underlying arterial lesion or thromboembolism of the infrapopliteal arteries. The aim of this study was to evaluate the efficacy and safety of image-guided surgical TE combined with routine intraoperative completion angiography in the treatment of ALI patients.
Methods: Between September 2020 and August 2022, this prospective study included all consecutive adult patients presenting to a tertiary center with unilateral ALI of Rutherford class II due to thromboembolic occlusion of native arteries who underwent image-guided surgical TE and routine completion intraoperative angiography. Adjunctive endovascular techniques (hybrid revascularization) including plain balloon angioplasty (PTA)±stenting or on-table lysis were used if underlying arterial lesions or residual thrombosis were detected on the intraoperative angiography, respectively. The primary outcome measures included technical success and 30-day major amputation rate. Perioperative complications, 1-year primary and secondary patency, limb salvage, mortality, and amputation-free survival rates were endorsed as secondary outcome measures.
Results: Image-guided surgical thrombectomy was done for 109 ALI patients (109 limbs), provisionally diagnosed as embolic (57 patients, 52.3%) or thrombotic (52 patients, 47.7%) arterial occlusion. Thromboembolectomy without adjunctive endovascular treatment was done in 38 patients (34.86%), whereas 71 patients (65.14%) required adjunctive PTA±stenting of underlying arterial lesions (60, 55.05%) or on-table lysis±PTA of residual thrombosis (11, 10.09%). The overall technical success rate was 92.66%. At 30 days, amputation and mortality rates were 3.67% and 5.5%, respectively. None of the patients had thrombectomy-induced arterial injuries. One-year follow-up data were available for 81 patients (74.3%). The Kaplan-Meier estimate of the 12-month primary and secondary patency, limb salvage, and amputation-free survival rates was 76.5%±0.04, 91.5%±0.03, 90.6±0.03, and 91.4±0.03%, respectively.
Conclusions: Image-guided TE combined with routine intraoperative angiography is a safe and effective technique for surgical TE in acute lower-limb ischemia patients with the advantage of immediate identification and treatment of underlying arterial lesions or residual thrombosis for optimal revascularization.

Background: R2CHA2DS2-VA score has been used to predict short and long-term outcomes in many cardiovascular diseases. This study aims to validate the R2CHA2DS2-VA score as a long-term major adverse cardiovascular events (MACE) predictor after carotid endarterectomy (CEA). Secondary outcomes were also assessed regarding the incidence of all-cause mortality, acute myocardial infarction (AMI), major adverse limb events (MALE), and acute heart failure (AHF).
Methods: From January 2012 to December 2021, patients (n ¼ 205) from a Portuguese tertiary care and referral center that underwent CEA with regional anesthesia (RA) for carotid stenosis (CS) were selected from a previously collected prospective database, and a posthoc analysis was performed. Demographics and comorbidities were registered. Clinical adverse events were assessed 30 days after the procedure and in the subsequent long-term surveillance period. Statistical analysis was performed by the KaplaneMeier method and Cox proportional hazards regression. Results: Of the patients enrolled, 78.5% were males with a mean age of 70.44 ± 8.9 years. Higher scores of R2CHA2DS2-VA were associated with long-term MACE (adjusted hazard ratio (aHR) 1.390; 95% confidence interval (CI) 1.173e1.647); and mortality (aHR 1.295; 95% CI 1.08e1.545).
Conclusions: This study demonstrated the potential of the R2CHA2DS2-VA score to predict long-term outcomes, such as AMI, AHF, MACE, and all-cause mortality, in a population of patients submitted to carotid endarterectomy
Abstract Background: Superficial femoral artery (SFA) is commonly affected with atherosclerotic peripheral arterial disease leading to chronic limb-threatening ischemia (CLTI). Subinitimal angioplasty (SIA) is a minimally invasive option. We aimed to examine the relationship between the Global Limb Anatomic Staging System and SIA midterm limb and survival-related outcomes.
Method: A prospective observational study was conducted on all patients with CLTI (Rutherford 4–6 or WIFI stages 2–4), with diseased femoropopliteal segment underwent SIA from August 2020 to September 2021. Patients with non-atherosclerotic SFA occlusion and those requiring primary major amputation were excluded. Multivariable Cox proportional hazard regression was performed to assess possible predictors of midterm clinical outcomes. Kaplan-Meier survival curves were used to estimate limb-based patency (LBP), limb salvage, amputation-free survival (AFS), and overall survival.
Results: The study included 138 patients with CLTI due to chronic total occlusion of the SFA and underwent SIA ± treatment of associated ipsilateral hemodynamically significant inflow/outflow disease. Primary technical success was achieved in 116 cases (84%), with primary patency at 1, 6, and 12 months being 100%, 84%, and 79% respectively, while the limb-salvage rate at 6 and 12 months was 100% and 94%, respectively. The result of the comparison between CLASS 1 and Global Limb Anatomic Staging System III (GLASS III) revealed significantly worse patency with GLASS III (p=0.005), and better overall survival (p=0.037), limb salvage (p=0.021), and AFS (p<0.001) with GLASS I.
Conclusion: Subinitimal angioplasty is a safe, effective, and minimally invasive treatment option for lengthy SFA lesions by avoiding the patients’ anesthesia and operative risk. Our study suggests that the GLASS stage may be a useful predictor of midterm limb and survival-related outcomes of this approach. GLASS III anatomy in comparison with GLASS I is associated with a statistically significantly worse LBP, limb salvage, AFS, and overall survival.
Abstract Chronic pelvic pain (CPP) is a prevalent condition in middle-aged women that represents a heavy social impact on the quality of life of those females. Treatment of pelvic congestion syndrome is a complex and controversial issue, but treatment can be one of 3 lines: medical therapy, endovascular treatment, and surgical intervention. The endovascular line was first introduced in 1993 and has been popular over other lines of treatment methods. This retrospective study was conducted in a tertiary university hospital over 24 months, from March 2019 to March 2021. Forty patients with PGS were managed by left ovarian vein TCFS. The Institutional Review Board waived the need for ethics approval or informed consent to use anonymized and retrospectively analyzed data. The mean age of enrolled women was 33.80 ± 6.54 years, ranging between 20 and 45 years. Trans-catheter ethanolamine foam embolization is an effective and safe method to treat pelvic and atypical lower limb varices.

Abstract Background: Carotid artery stenting (CAS) is considered an important tool in carotid revascularization. Carotid artery stenting is usually performed by using self-expandable stent with different designs. The stent design influences many physical characteristics. Also, it may affect the complication rate with special relevance to perioperative stroke, hemodynamic instability, and late restenosis.
Methods: This study comprised all consecutive patients who underwent carotid artery stenting for atherosclerotic carotid stenosis from March 2014 to May 2021. Both symptomatic patient and asymptomatic patients were included. Patients with a symptomatic carotid stenosis of ≥50% or asymptomatic carotid stenosis of ≥60% were selected for carotid artery stenting . Patients with fibromuscular dysplasia and acute or unstable plaque were not included. Variables of clinical relevance were tested in multivariable analysis using binary logistic regression model.
Results: A total of 728 patients were enrolled. The majority of this cohort was asymptomatic (578/728, 79.4%), while 150/ 728 (20.6%) were symptomatic. The mean degree of carotid stenosis was 77.82 ± 4.73%, with a mean plaque length of 1.76 ± 0.55 cm. A total of 277 (38%) patients were treated with Xact® Carotid Stent System. Successful carotid artery stenting was achieved in 698 (96%) of patients. Of these patients, stroke rate in symptomatic patients was nine (5.8%), while in asymptomatic patients was 20 (3.4%). In a multivariable analysis, the open-cell carotid stent was not associated with a differential risk for combined acute and sub-acute neurologic complications as compared with closed-cell stents. Patients treated with open cell stents had a significantly lower rate of procedural hypotension (P 0.0188) at bivariate analysis.
Conclusion: Carotid artery stenting is considered a safe alternative to CEA that can be used in selected average surgical risk patient. Different stent designs can affect the rate of major adverse events in carotid artery stenting patients, but further studies are necessary with avoiding different bias to study the effect of different stent designs.
Abstract: Background:
Patients undergoing carotid endarterectomy (CEA) may experiment intraoperative neurologic deficits (IND) during carotid cross-clamping. This work aimed to assess the impact of the Gupta Perioperative Myocardial Infarct or Cardiac Arrest (MICA) risk calculator in the IND.
Methods: From January 2012 to April 2021, patients undergoing CEA with regional anaesthesia for carotid stenosis with IND and consecutively control operated patients without IND were selected. A regressive predictive model was created, and a receiver operating characteristic (ROC) curve was applied for comparison. A multivariable dependence analysis was conducted using a classification and regression tree (CRT) algorithm. Results: A total of 97 out of 194 included patients developed IND. Obesity showed aOR = 4.01 (95% CI: 1.66–9.67) and MICA score aOR = 1.21 (1.03–1.43). Higher contralateral stenosis showed aOR = 1.29 (1.08–1.53). The AUROC curve was 0.656. The CRT algorithm differentiated obese patients with a MICA score ≥ 8. Regarding non-obese patients, the model identified the presence of contralateral stenosis ≥ 55% with a MICA ≥ 10.
Conclusion: MICA score might play an additional role in stratifying patients for IND in CEA. Obesity was determined as the best discrimination factor, followed by a score ≥ 8. A higher ipsilateral stenosis degree is suggested to have a part in avoiding procedure-related IND. Larger studies might validate the benefit of MICA score regarding the risk of IND.

Objectives Vascular access (VA) dysfunction, typically associated with progressive stenosis with subsequent failure, is a major problem associated with significant morbidity in hemodialysis (HD) patients and increased health care expenditure. The study aim was to report VA patency outcomes after intervention for flow dysfunction detected by duplex ultrasonography (DUS) surveillance associated with the presence of clinical indicator(s).
Patients and methods This prospective observational study was conducted in a tertiary university hospital (October 2018–October 2020). Patients with end-stage renal disease with newly created VAs underwent routine DUS surveillance every 3 months. Identified cases fulfilling at least one clinical indicator were included and underwent preemptive interventions. Thrombosed VA and asymptomatic lesions were excluded. Surveillance was subsequently performed using clinical, DUS and HD criteria to detect a failing/failed access. Patient follow-up and access-related events were analyzed.
Results The median age of the study group was 51 years, and 59.4% were male. Native VA was the predominant one. The mean access age was 13.9 months. Arm swelling was the major clinical presentation (32.9%). Most lesions were stenotic (86.5%), and juxta-anastomotic (42.9%) was the most common site. Balloon angioplasty +/− venous stent was used in all included patients. Multivariate analysis revealed that decreased access age, occlusive, multiple lesions, and lesion length more than5cm were significant predictors of primary patency loss.
Conclusion This study highlights the role of regular surveillance to stay ahead of the anticipated access dysfunction and to intervene in a timely manner. Integrated and efficient team work between HD providers and the vascular surgeons is crucial.

Background: Obesity has become a prevalent issue worldwide, leading to various complications such as hyperlipidemia, diabetes, and cardiovascular problems. Statins, as FDA approved anti-hyperlipidemic drugs still pose some concerns upon their administration. Recently, researchers have looked for natural products as an alternative to manage hyperlipidemia and obesity. Aim: This work aimed to study the hypolipidemic effect of Lepidium sativum garden cress (GC) from differen preparations; orally administered seeds, and hydrogel, in comparison to atorvastatin. Methods: GC hydrogel was prepared from the GC aqueous extract and pharmaceutically evaluated for it pH, spreadability, seeds content, homogeneity, rheology, and in vitro release. The rat’s body weight, bloo glucose levels, total lipid profile, and liver biomarkers were evaluated on obese rats for one month. In addition, the histopathology study was also performed. Results: GC hydrogel had acceptable pharmaceutical properties and showed a sustained release performance over 24h. Oral and topical GC significantly reduced the lipid profiles, blood sugar and AT, AST level than the negative control group and comparable to atorvastatin. It was found that oral GC showed significant effect on the percentage decrease in the rat’s body weight than the applied hydrogel. Histopathology study revealed a better outcome in the histological structure of pancreas and liver compared with rats feed on high fat diet post-treatment for one month. Conclusion: GC orally administered, or topically applied hydrogel could be a promising, safe alternative formulation to atorvastatin in managing hyperlipidemia and normalizing body weight of obese rats
