Current guidelines recommend at least a single antiplatelet or anticoagulant agent in symptomatic PAD and lifelong antithrombotic treatment after a revascularization procedure. The aim of this systematic review and meta-analysis was to investigate the efficacy and safety of direct oral anticoagulants (DOACs) in patients with peripheral artery disease (PAD). PAD is a significant cause of morbidity and mortality affecting over 200 million people worldwide. Methods: The present systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Risk ratios (RR) were calculated using the random effects model. Results: Overall, 10 studies were included in this systematic review and meta-analysis. In 4 studies, 14,257 patients with PAD were enrolled and they were assigned to receive either aspirin (ASA)+/- clopidogrel (N = 5,894) or DOAC+/- anti-platelet (e.g., ASA, clopidogrel) (n = 8,363). Non DOAC users were found to have higher reintervention rates (RR 1.12; 95% CI 1.01–1.24; P = 0.025) compared to DOAC users. No statistically significant difference was observed between the 2 groups, in terms of major bleeding (RR 0.78; 95% CI 0.50–1.23; P = 0.285), all-cause mortality (RR 0.98; 95% CI: 0.83–1.16; P = 0.818) and cardiovascular mortality (RR: 0.99; 95% CI: 0.73–1.333; P = 0.946) mortality. In addition, two real-world studies comparing DOAC with warfarin showed decreased rates of major cardiovascular events in the DOAC group. Conclusion: DOAC use alone or combined with an anti-platelet agent could be associated with lower re-intervention rates, without increasing the risk for adverse bleeding events. However, this study failed to detect any difference in terms of all-cause mortality, MACEs and MALEs between DOAC users and DOAC na?ve patients. Future studies are needed to better determine the efficacy and safety of DOACs in patients with PAD.

We instituted a unique hospitalist co-management program and assessed length of stay, 30-day readmission rates and mortality, and performed an overall cost-analysis. Methods: Hospitalist co-management of vascular surgery inpatients was implemented beginning April 2019, and data was studied until March 2020. We compared this data to an eight-month period prior to implementing co-management (7/2018 – 3/2019). Patient-related outcomes that were assessed include length of stay, re-admission index, mortality index, case-mix index. Cost-analysis was performed to look at indirect and direct cost of care. Results: A total of 1,062 patients were included in the study 520 pre co-management and 542 patients were post-comanagement. Baseline case-mix index was 2.47, and post-comanagement was 2.46 (P >0.05). In terms of average length of stay (aLOS), the baseline aLOS was 5.16 days per patient, while after co-management it was significantly decreased by 1.25 days to 3.91 days (P <0.05). This improvement in length of stay opened an average of 2.4 telemetry beds per day. Similarly, excess days per patient which reflects the expected length of stay based on comorbidities, improved from -0.59 to -1.65, an improvement of -1.46. Conclusions: Hospitalist co-management improves outcomes for vascular surgery inpatients, decreases length of stay, re-admission and mortality while providing a significant cost-savings. The overall average variable direct cost decreased by $1,732 per patient.

    查看更多>>摘要：? 2021Objective: Iatrogenic vascular injuries (IaVI's) appear to be increasing, with disparate prevalence across gender, race and ethnicity. We aim to assess the risk of IaVI's across these characteristics. Methods: Using the Nationwide Inpatient Sample for the years 2008 to 2015, we identified rates of IaVI's among the top ten most frequently performed inpatient procedures in the United States. Joint point regression was employed to examine the trends in the rates of IaVI's. We also calculated the adjusted odds ratios for IaVI's using survey logistic regression. Results: During the eight-year study period, a total of 29,877,180 procedures were performed (33.6% hip replacement, 14% knee arthroplasty, 11.2% cholecystectomy, 10.3% spinal fusion, 8.9% lysis of adhesions, 8% colorectal resection, 7.9% partial bone excision, 5% appendectomy, 0.6% percutaneous coronary angioplasty, 0.6% laminectomy). A total of 194,031 (0.65%) IaVI's were associated with these procedures. The incidence of IaVI's increased over time with an average annual percentage change (AAPC) of 4.2% (95% CI: 3.1, 5.4; P < 0.01). More females (105,747; 54.5%) than males (88,284; 45.5%) suffered IaVI's during their hospital admission (P < 0.01). Patients 70 years of age and older had the highest incidence of IaVI's (12,244,082; 34.3%; P ≤ 0.01). Among the ten index procedures, Non-Hispanic (NH) Whites underwent the highest proportion of procedures (14.1 procedures/100 hospitalizations; P < 0.01) and cholecystectomy was associated with the highest rate of IaVI's (19.4 per 1000 hospitalizations, P ≤ 0.01). Overall, patients from the lowest income quartile were least likely to suffer IaVI's (0.83 95% CI 0.79-0.88, P < 0.01) compared to the highest income quartile. All form of healthcare coverage increased the odds of IaVI's: Medicaid (1.07 95% CI 1.07-1.13, P < 0.01); Private insurance (1.35 95% CI 1.3-1.39, P < 0.01); Self-pay or no charge (1.45 95% CI 1.38-1.52, P < 0.01). IaVI's increased the odds of in-hospital mortality in all groups (1.25 95% CI 1.14-1.35, P < 0.01) and more pronounced in NH-Blacks (1.51 95% CI 1.15-1.99, P < 0.01). In the overall cohort, urban teaching hospitals observed the highest odds of in-hospital mortality (1.11 95% CI 1.07-1.15, P < 0.01). Conclusion: Between 2008 to 2015, IaVI's rates for the top ten most frequently performed inpatient procedures increased by 33.6% (4.2% annually; P < 0.01). The elderly, females, and Hispanics more frequently had hospitalizations complicated by IaVI's. Overall, IaVI's independently increased the adjusted odds of mortality by 25%. IaVI's were most fatal among Blacks, about 50% elevated risk of death compared to NH-Whites. These benchmarks will be critical to future efforts to reduce IaVI, and associated healthcare disparities.

    查看更多>>摘要：? 2021Objectives: Frailty has been correlated with poor outcomes after major surgery across multiple specialties, but has not been studied in patients undergoing open or endovascular repair of suprarenal and thoracoabdominal aortic aneurysms. Fenestrated endovascular aneurysm repair (FEVAR) has emerged as a lower risk alternative to open surgical repair (OSR) for patients with complex aortic aneurysms involving the visceral artery branches. The objective of the current study was to examine the relationship between frailty and peri-operative outcomes for FEVAR and OSR in patients with suprarenal and thoracoabdominal aortic aneurysms. Methods: The American College of Surgeons—National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients who underwent FEVAR or OSR for the years 2011 through 2017. Frailty was quantified using a modified 5-factor frailty index (mFI-5) that was previously validated for surgical patients. Frailty was correlated with the primary endpoint of 30-day mortality. Logistic regression was used to identify predictors of 30-day mortality. Results: A total of 675 FEVAR and 1,779 OSR operations were included in the analysis. The 30-day mortality rate was 3.0% for FEVAR and 7.1% for OSR (P = 0.002). Increasing frailty was significantly associated with higher 30-day mortality for both FEVAR (P = 0.018) and OSR (P = 0.0003). Independent predictors of 30-day mortality were frailty score (Odds Ratio [OR] 1.22 [per 0.1-unit increase]; P = 0.0005), type of repair (OSR versus FEVAR, OR 2.46; P = 0.0001), age (OR 1.03; P = 0.0025), female sex (OR 1.61; P = 0.007), Hispanic ethnicity (OR 2.68; P = 0.021), American Society of Anesthesiology [ASA] class (OR 1.57; P = 0.035), preoperative dialysis (OR 3.45; P = 0.032), and history of bleeding disorder (OR 2.60; P < 0.0001). Conclusions: Frailty, as measured using a mFI-5 score, is an independent predictor of 30-day mortality, overall complications, and length of stay after FEVAR or OSR. Frailty should be used to identify patients at high risk of adverse postoperative outcomes to determine if this risk is modifiable or whether nonoperative is the most appropriate option. FEVAR may offer improved 30-day outcomes, compared to OSR, for the frailest patients.

    查看更多>>摘要：? 2021Background: The aim of the study was to evaluate the short-term and mid-term technical and clinical outcomes of the Bolton Treo endograft in subjects with abdominal aortic aneurysm (AAA) requiring endovascular aortic repair (EVAR) and assess if presence of hostile proximal neck would represent a risk factor for increased failure rates. Methods: A retrospective review of all consecutive patients who had undergone elective or non-elective EVAR with the Bolton Treo endograft at 5 institutions located in the North-East of Italy (January 2016–December 2020) was performed. The main exposure variable for this study was presence of hostile (HAN) or friendly (FAN) aortic neck. Results: A total of 137 consecutive patients were treated with the Bolton Treo endograft at participating institutions; of these 63 (46%) presented HAN while 74 (54%) had FAN. At baseline, no significant differences were observed in the distribution of demographics and comorbidities between study groups. Two type Ia endoleaks (EL) were detected at completion angiography, all in patients with HAN but none in patients with FAN (3% vs. 0%, P = 0.04), but no type III EL were identified in the whole cohort. The median duration of follow-up in the study cohort was 30 months (IQR 22–34 months) and was similar between study groups (P = 0.87). At 3-years, survival estimates were 89% and 91% (P= 0.82) in patients with HAN and FAN, respectively. At three years, patients with HAN had significantly lower freedom from type IA endoleak as compared with patients with FAN (87% vs. 94%, P= 0.02). No significant differences were found between study groups in the three-year estimates of freedom from reinterventions (80% vs. 86%, P= 0.28). Using cox proportional hazards, presence of type II EL (HR 3.15, 95%CI 1.18–8.5, P= 0.02) and presence of type IA EL (HR 4.22, 95%CI 1.39–12.85, P= 0.01) were found as independent predictors for reinterventions in univariate analysis, although they were no longer significant in the multivariate model. Freedom from sac increase >5mm at three years were not significantly different between study groups (92% vs 91%, P= 0.95). Conclusions: Within a contemporary multicentric real-world experience, EVAR with the Bolton Treo endograft shows a satisfactory safety profile in the immediate postoperative phase and acceptable outcomes during mid-term follow-up. Presence of HAN is correlated with development of type Ia EL (either early following stent-graft implantation or late after EVAR) which, in turn, may represent a significant factor leading to reinterventions.

    查看更多>>摘要：? 2021Background: Endovascular aortic repair (EVAR) has advanced the care of patients with ruptured abdominal aortic aneurysms (rAAA) with improved early postoperative morbidity and mortality. However, this comes at the cost of a rigorous postoperative surveillance schedule to monitor for further aneurysmal degeneration. Adherence to surveillance recommendations is known to be poor in the elective setting, but has yet to be studied in the ruptured population. The aim of this study is to investigate predictors of incomplete surveillance after EVAR for rAAA (rEVAR) and examine how adherence impacts outcomes. Methods: This was a retrospective case control study of patients undergoing rEVAR at a multiple hospital single healthcare center (2003–2020). Patients were excluded if they underwent open conversion during their index hospitalization or died within 60 days of surgery. Follow-up was broadly categorized as complete surveillance (60-day postoperative visit and annually thereafter) or incomplete surveillance, comprising both patients with less than recommended surveillance (minimal surveillance) and completely lost to follow-up (LTF). Any follow-up was defined as patients with complete or minimal surveillance. We investigated predictors of complete versus incomplete surveillance by multivariate logistic regression. Secondary outcomes included overall survival and cumulative incidence of reintervention controlling for the competing risk of mortality, generating hazard ratios (HR) and subdistribution hazard ratios (SHR). Results: One-hundred and sixty patients (mean age 74 ± 10.1 years, 81.2% male) out of 673 total rAAA met study inclusion criteria. Complete surveillance was seen in 41.3% of our cohort, with the remainder with minimal surveillance (29.4%) or LTF (29.4%). Incomplete surveillance was associated with male sex (odds ratio [OR] 2.56; 95% CI 1.02–6.43), lack of a primary care provider (PCP; OR 0.20; 95% CI 0.04–0.99), and longer driving distance from home to treating hospital (OR 2.37; 95% CI 1.08–5.20). Survival was not different between complete and incomplete surveillance groups, however any follow-up conferred improved survival over LTF (HR 0.57; 95% CI 0.331–0.997; P = 0.049). Reintervention was associated with incomplete surveillance (SHR 0.29; 95% CI 0.11–0.75), and discharge to a facility (SHR 0.25; 95% CI 0.067–0.94). Conclusions: Incomplete surveillance was observed in over 50% of patients who underwent rEVAR and was associated with male sex, lack of PCP, and longer driving distance. Any follow-up conferred a survival benefit, yet incomplete surveillance was associated with a lower risk of reintervention. Targeted strategies to prevent LTF, and less stringent, personalized follow-up plans that may confer similar survival benefit with better patient adherence should be investigated.

    查看更多>>摘要：? 2021 Elsevier Inc.Background: In the Brazilian public health system, conventional surgery is the standard procedure for treatment of varicose veins (VV). We aimed to compare clinical and quality of life (QoL) results of patients subjected to bilateral treatment of VV by a single-procedure or staged-procedure approach. Methods: A total of 111 patients undergoing bilateral treatment for VV were treated either by a single-surgery or 2 staged procedures (minimal: 30-day interval) depending on institutional protocol. Patients were evaluated with respect to clinical symptoms and quality of life markers before and after treatment, by use of the VEINES-Sym/QoL and EQ5D-5L scores, and these results were then compared between groups. Results: QoL scores improved in general after treatment. VV specific symptoms and QoL aspects improved equally between the Staged-procedure and Single-surgery groups (VEINES-Sym mean variation 29.7 ± 2.1 vs. 29.9 ± 2.7, respectively; P = 0.340 and VEINES-QoL mean variation 5.5 ± 3.4 vs. 4.5 ± 4.3, respectively; P = 0.369). General QoL, however, showed more improvement in the Staged-procedure than the Single-surgery group (EQD5-5L mean increase 0.1678 ± 0.1555 and 0.0785 ± 0.1384, respectively; P = 0.007). When propensity matched, patient subgroups maintained this same differences in QoL results. Conclusions: Our findings suggest that the both the Staged- and Single-surgery approach for VV surgical treatment incur similar improvement in disease-specific QoL, and that the Staged-approach may impose less of a burden in the patients’ recovery.

    查看更多>>摘要：? 2021 Elsevier Inc.Background: Intravascular ultrasound (IVUS) may be a useful adjunct to lower extremity peripheral vascular interventions (PVI) in certain clinical scenarios. We aimed to identify patient- and physician-level characteristics associated with the use of IVUS during first-time femoropopliteal PVI. Methods: We included all Medicare beneficiaries undergoing elective femoropopliteal PVI for claudication or chronic limb-threatening ischemia between 01/01/2019 and 12/31/2019. We excluded patients with prior open or endovascular femoropopliteal intervention and all physicians performing ≤10 PVI during the study period. We calculated the proportion of patients who had IVUS performed as part of their index PVI for each physician. Hierarchical logistic regression was used to evaluate patient- and physician-level factors associated with use of IVUS. Results: We identified 58,552 patients who underwent index femoropopliteal PVI, of whom 11,394 (19%) received IVUS. A total of 1,628 physicians performed >10 procedures during the study period, with IVUS utilization ranging from 0–100%. After hierarchical regression, claudication (versus chronic limb-threatening ischemia: OR 1.23, 95% CI 1.11–1.36), stenting (versus angioplasty alone: OR 1.57, 1.33–1.86) and atherectomy (versus angioplasty alone: OR 2.09, 1.83–2.39) were associated with higher odds of IVUS utilization. Higher-volume providers (tertile 3 vs. tertile 1: OR 3.78, 2.43–5.90) and those with high rates of service provided in an office-based laboratory (tertile 3 vs. tertile 1: OR 10.72, 6.78–19.93) were more likely to utilize IVUS. Radiologists (OR 11.23, 5.96–21.17) and cardiologists (OR 1.97, 1.32–2.93) used IVUS more frequently than vascular surgeons. Conclusions: Wide variability exists in the use of IVUS for first-time femoropopliteal PVI. The association of IVUS with claudication, atherectomy, and office-based laboratories raises concern about its potential overuse by some physicians.

    查看更多>>摘要：? 2021 Elsevier Inc.Background: Superficial femoral artery and profunda patency has been shown to affect aortofemoral bypass (AFB) limb patency. However, the effect of retrograde flow through the external iliac artery (EIA) is unknown and is the subject of this analysis. Methods: Institutional AFB data from 2000 to 2017 were gathered, excluding that where Superficial femoral artery /EIA patency could not be determined. The cohort was divided into limbs with and without EIA occlusion; primary outcome was limb-based primary patency. Kaplan-Meier estimated patency; cox proportional-hazards model evaluated EIA patency while controlling for other factors. Results: Over the study period, there were AFB 557 limbs in 281 patients. Of the 435 AFB limbs in 220 patients that met inclusion criteria and were included in the analysis, 162 had EIA occlusion and 273 had a patent EIA. Mean age was 69.6 ± 9.0. EIA occlusions were more common in male patients (59.9% vs. 44.6%; P = 0.001), patients with CAD (43.8% vs. 34.1%; P = 0.042), COPD (34.6% vs. 20.5%; P = 0.001), and CHF (14.8% vs. 5.9%; P = 0.002). Limbs with EIA occlusions more often underwent end-to-side proximal anastomosis (40.7% vs. 24.2%; P < 0.001) and simultaneous infrainguinal bypass (7.4% vs. 0.7%; P < 0.001). Median clinical follow-up was 4.4 years (IQR: 1.6–8.4). Five-year primary patency was 83.1% (95% CI: 74.5–90.0%) for EIA occlusion limbs and 85.9% (95% CI: 80.2–90.0%) with patent EIA limbs (P = 0.96). While controlling for other factors, EIA stenosis or occlusion did not affect primary patency. For patients with a proximal occlusion (occluded aorta, occluded common iliac, or end-to-end proximal anastomosis) and occluded SFA (N = 73), EIA occlusion had a HR of 1.92 for loss of patency, but this was not statistically significant. Conclusions: EIA patency did not influence primary patency in the overall cohort Further investigation on the topic in specific patient subgroups is warranted to determine the effect of EIA patency.

    查看更多>>摘要：? 2021Background: For same-day discharge lower extremity arterial disease (LEAD) endovascular procedures, femoral manual compression could be an alternative to arterial closure devices. The aim of this study was to assess the security and efficacy of same-day discharge after manual compression in patients treated for LEAD endovascular revascularization with 5F sheath. Methods: FREEDOM OP was a national multicenter, prospective, single arm study. Patients with symptomatic LEAD (Rutherford 2–5) and eligible for same-day discharge were included. The primary endpoint was the total in-hospital admission rate, which includes overnight surveillance and rehospitalization rate at 1 month. Results: Between September 2017 and August 2019, 114 patients were included. The mean age of the patients was 66 ± 10 years and most of them were claudicant (103; 94%). Mainly femoropopliteal lesions were treated (178; 70%) and the technical success was 97%. One hundred forty-two 5F stents and fifty one 5F drug coated balloon were delivered. The mean manual compression duration was 13 ± 4 min. Major access-related complications rate was 4.5%. Total in-hospital admission rate was 11%. Seven patients had overnight surveillance and 5 were rehospitalized (2 for the target lesion). No rehospitalisation was carried out within 24 hr after discharge. No major cardiovascular event, including death, was observed. The patients were significantly improved in term of clinical status (P < 0.0001) and hemodynamic (P < 0.0001) in comparison to baseline. Conclusion: FREEDOM OP showed that manual compression is feasible and safe for same-day discharge after LEAD revascularization with 5F sheath femoral approach.
