However, little is known about differences in social media use among physicians of varying specialties and its impact on recruitment of trainees. Our objective was to describe differences in social media use among vascular interventional proceduralists at academic training institutions. Methods: We identified institutions with training programs in vascular surgery (VS), interventional radiology (IR), and interventional cardiology (IC). Faculty providers were identified in each specialty at these institutions. A standardized search was used to identify non-anonymous social media profiles on Facebook, Instagram, and Twitter in September 2019. Influencers were defined as physicians with more than 1,000 Twitter followers. Follow ratio was defined as the number of followers divided by the number of accounts followed. Between-specialty differences were analyzed. Results: A total of 1,330 providers (n = 454 VS, n=451 IR, n = 425 IC) were identified across 47 institutions in 27 states. Across all physicians, a minority of providers utilize social media (Facebook: 24.9%, n = 331; Instagram: 10.8%, n = 143; Twitter: 18.0%, n = 240). VS were significantly more likely to use Instagram (P = 0.001) but there was not a significant difference in utilization of Facebook and Twitter. Among Twitter users, VS had fewer followers on average (median 178, inter-quartile range [IQR] 39-555) than IR (median 272, IQR 50-793, P = 0.26) and IC (median 286, IQR 71-1257, P = 0.052). IC were most likely to be influencers (30.9%, n = 25) followed by IR (17.9%, n = 15) and VS (10.7%, n = 8, P = 0.006). On average, interventional cardiologists had the highest follow ratio (mean 4.9 ± 7.1) compared to interventional radiologists (mean 3.2 ± 5.5) and vascular surgeons (mean 2.5 ± 3.3, P < 0.001). Conclusion: A minority of academic vascular interventional proceduralists utilize social media in a non-anonymous manner. On Twitter, interventional cardiologists are most likely to be influencers based on number of followers and, on average, have the highest follow ratio. Vascular surgeons could potentially benefit from pursuing greater influence and visibility on social media as a means to recruit trainees.

    查看更多>>摘要：? 2021 The AuthorsBackground: Endovascular access is usually achieved through the common femoral artery due to its large size and accessibility. Access through the upper extremity can however be necessary due to anatomic reasons, obesity, or peripheral arterial disease. The 2 main methods of access are surgical cutdown and percutaneous puncture. In this single-centre retrospective cohort study we compared complication risks for both surgical cutdown and percutaneous puncture of an upper arm approach. Materials and Methods: Data was obtained from patients receiving endovascular access through the brachial or axillary artery between 2005 and 2018. A total of 109 patients were included. Patient demographics including age, sex, medical history, smoking status, and actual medication were registered, as well as postoperative complications including hematoma, thrombosis, dissection, infection, pseudoaneurysm, nerve injury, reoperation, and readmission. Results: Access was achieved through surgical cutdown in 53% (n = 58) and through percutaneous puncture in 47% (n = 51) of patients. Fifty-eight percent (n = 63) received access via the brachial artery (BA) and 42% (n = 46) via the axillary artery. Complication rate was 25.0% (3 of 12) for surgical cutdown via the BA, 29.4% (15 of 51) for percutaneous puncture via the BA, and 10.9% (5 of 46) for surgical cutdown via the axillary artery. Major complication rate was 8.3% (1 of 12) for surgical cutdown via the BA, 13.7% (7 of 51) for percutaneous puncture via the BA, and 4.3% (2 of 46) for surgical cutdown via the axillary artery. There was no association between baseline patient characteristics and complication rate. Conclusions: In this nonrandomized retrospective study, surgical cutdown via the axillary artery was the safest option with fewest complications, but selection of patients may have blurred the results. Surgical cutdown and percutaneous puncture seem equally safe in terms of complication rate in the BA.

    查看更多>>摘要：? 2021Objective: For treatment of infected femoral artery pseudoaneurysms (IFAPs) with the covered stent, debridement technique is important but frequently ignored. Our study aims to review our experience and outcomes of patients undergoing covered stents placement and debridement with vacuum sealing drainage (VSD). Methods: This study retrospectively analyzed 41 intravenous drug addicts with IFAP who received covered stent implantation and debridement with VSD from January 2015 to December 2020. The diagnosis was based on the previous history of local injection and the presence of pulsatile mass at the injection site. All cases were confirmed by CT angiography (CTA), ultrasound, or digital subtraction angiography (DSA). Technical success, time of wound care, and clinical outcomes were evaluated. Results: Technical success was achieved in all patients. The interval from diagnosis to treatment was 26 ± 11 hours. The time of continuous drainage with VSD was 18.79 ± 6.56 days. 38 patients (92.68%) with fresh granulation tissue were sutured and discharged from the hospital. Stents in 31(91.18%) of 34 cases were patent during follow-ups. Three patients had stent occlusion caused by thrombosis, and two of them were complicated with stent infection. The two infectious stents were removed and the femoral arteries were ligated. One of them received open-surgical reconstruction with the great saphenous because of claudication. Two patients were admitted to the hospital for rebleeding caused by drug abuse relapse. Conclusions: Covered stents placement is convenient and rapid to control massive hemorrhage in IFAPs of intravenous drug abuse. Early debridement of infected tissue with continued VSD may shorten the time of wound care and make the incidence of stent infection relatively low. Meanwhile, the patency in a short time follow-up is acceptable. These results indicate that covered stents implantation with VSD may be a safe, effective, and feasible measure for the treatment of IFAPs.

    查看更多>>摘要：? 2021Background: Numerous angiography-based peripheral arterial disease classification schemes have been developed to stratify severity of preoperative patient disease, but few studies have correlated angiography-based anatomic classification schemes to postoperative outcomes. This study examined whether a proposed pre-operative angiography scoring system was predictive of outcomes after isolated common femoral endarterectomy with profundaplasty (CFEP). Methods: A retrospective review was conducted of patients treated with isolated CFEP for claudication and/or rest pain at a single institution from 2016–19. Pre-operative angiograms were assessed quantitatively by 4 blinded surgeons across 3 domains: profunda stenosis, profunda disease length, and outflow disease severity. Table I describes the proposed angiography scoring system. Internal consistency reliability of rater scores was calculated using Cronbach alpha. Outcomes included clinical improvement, further interventions, major amputations, mortality, and mean increase in ankle-brachial index (ABI) at 30 days, and 6 months. McNemar tests, between-group t-tests, Pearson correlations, and linear regression were used. Results: Clinical Outcomes 88% of patients (n = 22) had clinical improvement at 30 days; the remaining 12% of patients (n = 3) required further interventions. One patient (4%) required major amputation between 30 days and 6 months for recurrence of rest pain that had initially resolved after isolated CFEP. There was 0% mortality during the study period. Mean ABI increased by 0.15 ± 0.21 at 30 days, and by 0.06 ± 0.21 at 6 months. Angiography Scoring System Profunda stenosis score was associated with clinical improvement at 6 months (P = 0.04). A profunda stenosis score of ≥2.6 was strongly associated with 6-month clinical improvement (64% of those ≥ 2.6 improved, versus 15% of those <2.6, P = 0.15). Profunda stenosis score was associated with ABI improvement at 30 days (r = 0.73, P = 0.01) and 6 months (r = 0.82, P = 0.007). Profunda disease length score was associated with clinical improvement at 30 days (P = 0.002). 100% of patients with a profunda disease length score of ≥1.5 clinically improved at 30 days, versus 67% of those with <1.5 (P = 0.04). Angiography scores were not found to be associated with further intervention, major amputation, or mortality. Cronbach alpha for profunda stenosis, profunda disease length, and outflow severity scores were 0.90, 0.90, and 0.79, respectively, indicating strong internal consistency. Conclusions: This institutional angiography scoring system successfully predicts clinical improvement following CFEP. Higher profunda stenosis and profunda disease length scores were most predictive of operative success within 6 months. Future validation studies will investigate these outcomes in a larger population, and over a longer period.

    查看更多>>摘要：? 2021 Elsevier Inc.Objectives: To compare drug-coated balloon (DCB) and bare metal stent (BMS) for primary lesions in femoropopliteal artery disease in Chinese population and to make subgroup analysis between the groups. Methods: Patients with primary lesions who underwent BMS or DCB treatment of a single tertiary vascular center were included and followed up for 24 months. Clinical and anatomic status were reported using the criteria recommended by the Society for Vascular Surgery. The primary endpoint included primary patency, clinically target limb revascularization, composite safety endpoint and all-cause death over 24 months assessed by Kaplan-Meier. Secondary endpoints included technical success rate and stent-related complications. Results: A total of 284 patients with 324 limbs were pooled into analysis and most of the baseline characteristics did not show significant difference. A total of 74 in BMS group and 71 in DCB group were claudicants while 83 in BMS group and 56 in DCB group suffered from chronic limb threatening ischemia (CLTI). The mean cumulative lesion length was 18.7 ± 9.8cm in BMS group while 17.2 ± 10.3cm in DCB group. Kaplan-Meier estimates of primary patency were 75.3% and 80.9% for BMS and DCB groups at 12 months while decreased to 63.9% and 70.2% at 24 months (log-rank P = 0.167), respectively. Freedom from clinically driven target limb revascularization was 86.8% and 92.7% for BMS and DCB groups at 12 months while dropped to 82.5% and 85.9% at 24 months (log-rank P = 0.342). Estimates of primary patency between BMS and DCB group did not show significant difference on lesions with poor runoff (58.8% vs. 67.3%, log-rank P = 0.127), severe calcification (64.5% vs. 69.4%, log-rank P = 0.525) and popliteal artery involvement (59.3% vs. 60.3%, log-rank P = 0.695) at 24 months. The overall survival (92.6% for BMS, 90.3% for DCB, log-rank P = 0.391) and freedom from composite safety endpoint (79.3% for BMS, 79.2% for DCB, log-rank P = 0.941) showed no significant difference at 24 months. Conclusions: Over the 24 month follow-up, BMS and DCB showed equivalent efficacy and safety outcomes for primary femoropopliteal artery disease, which indicated the reduction of permanent metallic implant insertion might be possible.

    Early Outcomes of Complex Vascular Reconstructions in Lower Extremities Using Spiral and Panel Vein Grafts

    Wu H.Wang Z.Li M.Liu Q....
    9页
    查看更多>>摘要：? 2021Background: Spiral saphenous vein grafts (SSVG) or paneled vein grafts (PVG) can be used when the diameter of the autologous great saphenous vein does not match the vessel that needs to be repaired. This study aimed to present early results of complex vascular reconstruction with SSVGs and PVGs in the lower extremities. Methods: From May 2019 through January 2021, 6 SSVGs and 3 PVGs were used for vascular reconstruction in 9 patients. Patient data were collected retrospectively, including age, gender, cause of vascular pathology, target vessels, concomitant injury, surgical method, additional surgical methods, and hemodynamic status. The Kaplan-Meier method was used to calculate the rate of freedom from reintervention. Results: Among these patients, 7 had trauma, 1 had graft infection, and 1 had vascular reconstruction after tumor excision. The mean duration of follow-up was 6 ± 6.6 months (range 1–19 months). The rate of freedom from reintervention for any reason was 77.8% at 1 year. Two patients underwent amputation after vascular reconstruction with patent vascular reconstructions. One of the 2 amputations was performed because of infection, and the other was due to ischemia >24 hr. The success rate of reconstruction was 100%, and the primary patency rate was 100%. The rate of limb salvage was 77.8%. There was no death, bleeding, embolism, skin ulcers, graft-related complication, or aneurysmal dilation during follow-up. Conclusions: SSVG and PVG were associated with low infection rates and satisfactory short-term patency rates. Both 2 grafts may be good choices when there is a diameter mismatch in vascular reconstructions.

    查看更多>>摘要：? 2021Objectives: This study aimed to investigate the relationship between pre-procedure high-sensitivity C-reactive protein (hsCRP), free fatty acid (FFA), and uric acid (UA) levels and post-procedure mortality and morbidity of endovascular revascularization of arterial femoropopliteal occlusion lesions. Methods: This was a retrospective review of clinical data retrieved from a prospectively held database in Peking Union Medical College Hospital. A total of 71 Patients who underwent endovascular treatment (EVT) for femoropopliteal occlusive disease between January 1, 2014 and November 1, 2017, were included in this study. Endpoints were defined as major adverse limb events (MALE; target vessel revascularization, amputation, or disease progression) and major adverse cardiovascular events (MACE; stroke, myocardial infarction, or all-cause death) during the entire follow-up period. Univariate and multivariate Cox proportional hazards regression models were used to evaluate the relationship of elevated biomarker levels (hsCRP, FFA and UA, measured by immunoturbidimetry assay, enzymatic assay and enzymatic assay, respectively) to MALE and MACE outcomes. Results: Seventy-one patients (72 limbs) with sufficient follow-up information were included in the analysis. The mean age was 69.7 ± 8.6 years; 21.1% were female. The Rutherford class of target limbs were ≥ 3. The median follow-up was 36 (range 18-59 months). Univariate analyses revealed that patients with elevated hsCRP levels had an increased risk of MALE (hazard ratio [HR], 2.682; 95% confidence interval [CI], 1.281-5.617, P = 0.009). High FFA levels were associated with an increased risk of MALE (HR, 2.658; 95% CI, 1.075-6.573; P = 0.034). Multivariate analyses demonstrated that elevated hsCRP values (HR, 4.015; 95% CI, 1.628-10.551; P = 0.003) and FFA value (HR, 3.034; 95% CI, 1.102-8.354; P = 0.032) were both significantly associated with increased MALE. Elevated UA levels predicted MACE in the presence of confounders (HR, 11.446; 95% CI, 1.367-95.801 P = 0.023). Conclusion: Pre-procedure hsCRP and FFA levels could serve as predictors of adverse events after EVT in patients with arterial femoropopliteal occlusive disease. The role of UA in MACE may warrant further investigation, because the correlation is not as powerful as the other two in the study.

    查看更多>>摘要：? 2021Background: Surgical site infections (SSIs) following lower extremity amputations (LEAs) are a major cause of patient morbidity and mortality. The objectives of this study are to investigate the annual incidence of SSI and risk factors associated with SSI after LEA in diabetic patients. Methods: LEAs performed on diabetic patients between 2005 and 2017 were retrospectively analyzed from the American College of Surgeons National Surgical Quality Improvement Program database. Incidence rates were calculated and analyzed for temporal change. Multivariable logistic regression was conducted to identify the independent predictors of SSIs in LEA. Results: In 21,449 diabetic patients, the incidence of SSIs was 6.8% after LEA, with an overall decreasing annual trend (P = 0.013). Amputation location (below-knee in reference to above-knee) [OR (95% CI): 1.35 (1.20 – 1.53), P <0.001], smoking [OR (95% CI): 1.25 (1.11 – 1.41), P <0.001)], female sex [OR (95% CI): 1.16 (1.03 – 1.30)], preoperative sepsis [OR (95% CI): 1.24 (1.10 – 1.40), P <0.001], P = 0.013], emergency status [OR (95% CI): 1.38 (1.17 – 1.63), P <0.001], and obesity [OR (95% CI): 1.59 (1.12 – 2.27), P = 0.009] emerged as independent predictors of SSIs, while moderate/severe anemia emerged as a risk-adjusted protective factor [OR (95% CI): 0.75 (0.62 – 0.91), P = 0.003]. Sensitivity analysis found that moderate/severe anemia, not body mass index (BMI) class, remained a significant risk factor in the development of SSIs in below-the-knee amputations; in contrast, higher BMI, not preoperative hematocrit, was significantly associated with an increased risk for SSI in above-the-knee amputations. Conclusions: The incidence of SSIs after LEA in diabetic patients is decreasing. Overall, below-knee amputation, smoking, emergency status, and preoperative sepsis appeared to be associated with SSIs. Obesity increased SSIs in above-the-knee amputations, while moderate/severe preoperative anemia appears to protect against below-the-knee SSIs. Surgeons should take predictors of SSI into consideration while optimizing care for their patients, and future studies should investigate the role of preoperative hematocrit correction and how it may influence outcomes positively or negatively.

    Stickley S.M.Brahmbhatt R.Rohrer M.J.Kempe K....
    7页
    查看更多>>摘要：? 2021Background: Data is scarce regarding the need for early re-amputation to a higher anatomic level. This study seeks to define outcomes and risk factors for re-amputation. Methods: Patients undergoing primary major lower extremity amputation were identified within the 2012-2016 ACS-NSQIP database. Demographics, outcomes, and peri-operative characteristics were compared, and multivariable logistic regression model was used to determine association with early re-amputation. Results: Over a 4-year period, 8306 below knee amputations and 6367 above knee amputations were identified. Thirty-day re-amputation occurred in 262 patients (1.8%) and was associated with increased length of stay (12.9 vs. 7.3 days, P < 0.001), higher rates of readmission (64.9% vs. 13.6%, P < 0.001), and overall complications (69.5% vs. 39.3%, P < 0.01). On multivariable analysis, advanced age (OR 1.02, CI 1.01-1.03), smoking (OR 1.75, CI 1.32-2.33), dialysis dependence (OR 1.67, CI 1.23-2.26), preoperative septic shock (OR 2.53, CI 1.29-4.97), and bleeding disorders (OR 1.72, CI 1.34-2.22) were associated with early re-amputation. Conclusions: Thirty-day re-amputation rates are low, but are associated with significant morbidity, prolonged hospitalization, and frequent readmissions.

    查看更多>>摘要：? 2021 The Author(s)Purpose: To assess a specific classification of the foot atherosclerotic disease concerning the angiosomal source arteries, the connected foot arches and attached collaterals for Rutherford 5, CLTI patients. To compare eventual analogies of this novel grading system with previously reported GLASS/GVG inframalleolar patterns of occlusive disease (P0-P2). Materials and Methods: A series of 336 ischemic feet (221 diabetics) were selected and retrospectively analyzed. For each angiographic pattern of inframalleolar atherosclerotic disease, 4 severity classes of targeted angiosomal artery path (TAAP), associating 4 other classes concerning linked foot arches (LFA) and collaterals occlusive disease were described. By associating the 4 TAAP with the 4 others parallel LFA and collaterals classes, 4 novel anatomical “Grades” (A-D) of occlusive disease were described. Limb salvage was studied between groups of diabetic and non-diabetic patients. Results: Using a primary endovascular approach, limb preservation comparison of grade A/B proved without significance for diabetics (P = 0.032) and non-diabetics (P = 0.226). Comparison in diabetics and/or non-diabetics between A/C (P = 0.045 and 0.046), A/D (P = 0.027 and 0.030,B/C (P = 0.009 and 0.038), and B/D (P = 0.006 and P = 0.042), as well as C/D groups (P = 0.048 and P = 0.034) proved ponderous. Parallel analysis of similar grades (A/A, B/B, etc.) with, or without diabetes appeared without significance (P > 0.05). Further comparison between grades A+B (assigned as P0/GVG), versus C (P1), and D (P2), proved significant (P < 0.0001). Conclusion: The present grading system proposes a useful correlation between the severity of foot angiosomal arteries, arches, and collaterals disease and limb salvage, confirming the clinical significance of P0-P2 GVG severity score. This analysis also points the limits of EVT to be probably avoided in grade D patients.
