It also found that the rate of emissions differs between different operations, suggesting a role in optimizing fluoroscopy and intraoperative techniques to lower emissions.

Prior studies have shown that lower extremity amputation is associated with increased risk of developing depression in the postoperative period. However, these studies are primarily single center, confined to specific populations, or do not include analysis over various timepoints. The objective of this study was to assess the association between lower extremity amputation level, level of amputation, and postoperative development of depression. This information will allow vascular surgeons to identify patients who are at a high risk for the development of depression after amputation and make the necessary psychiatric referrals.</p><p><strong>Methods: </strong>48,568 adult patients who underwent PAD-related lower extremity amputation were identified from the TriNetX Research database following exclusion of those with preoperative depression or use of antidepressants. Propensity score matching was used to develop comparable major amputation (Above- and Below-Knee Amputations) (I) and minor amputation cohorts (Toe and foot amputations) (II), yielding two groups each with 14,853 patients. Primary outcomes included postoperative diagnosis of major depressive disorder (MDD), prescription of antidepressants, and mortality.

At 1 year, the incidence of MDD, antidepressant prescriptions, and mortality was 7.7% vs. 6.4% (p <0.001), 28.6% vs. 18.5% (p <0.001) and 20.7% vs. 12% (p <0.001), respectively.

Patients who underwent major amputations and major amputations after minor amputations were more likely to experience postoperative MDD and require antidepressant prescriptions than patients who underwent minor amputation alone.

All antithrombotic prescriptions after initial LER were abstracted by pharmacists. Demographics and clinical characteristics of patients who received clopidogrel after initial LER were evaluated. Comparison of patients who received extended clopidogrel therapy (&gt; 12 months) compared to limited clopidogrel therapy (≤ 12 months) was performed.

Clopidogrel was the most commonly used medication in 69.8% (N=1,363). Among patients treated with clopidogrel after LER, 69.5% (N=947) received extended therapy (&gt;12 months). Patients who received extended clopidogrel therapy were more likely to have had a prior endovascular procedure (21.8% vs 15.2%, P=0.005), while those who received limited therapy (≤12 months) were older (72 vs 69, P&lt;0.001) and more likely to have congestive heart failure (21% vs 14%, P=0.001) and chronic renal insufficiency (22.2% vs 15.6%, P&lt;0.004).

Optically stimulated luminescence dosimeters were placed outside the lead apron at the thyroid and sternum positions for one attending surgeon and all assisting fellows performing FGIs. Cases were stratified according to fellow training stage: first 6 months in the first year (PGY6) and final six months of the second year (PGY7). Operator radiation dose was calculated based on a calibration of 80 kVp. Procedural reference air kerma (RAK), fluoroscopy time, dose area product (DAP) and patient BMI were recorded. Scatter fractions were measured with thyroid and sternum counts to DAP ratio, and DAP/RAK ratio (a surrogate for collimation and use of magnification). Paired Wilcoxon and chi-square tests were performed to identify statistical significance of training stage on radiation dose exposure and performance of radiation reduction.</p><p><strong>Results: </strong>A total of 40 FGIs were performed: 21 cases with PGY-6 fellows and 19 cases with PGY-7 fellows. Higher median thyroid and sternum radiation doses were observed for PGY-6 fellows compared to PGY-7 fellows, respectively (82 μGy [IQR 47-94] vs 44 μGy [IQR 30-57], P=0.009; 89 μGy [IQR 75-128] vs 54 μGy [IQR 48-77], P =0.007). Scatter fractions as measured by the thyroid/DAP and sternum/DAP ratios were significantly higher for first-year fellows (2 vs 1, P = 0.018; 2.64 vs 1.23, P = 0.041). There was no difference in the source to image distance or the average field size as measured by the DAP/RAK ratio.</p><p><strong>Conclusions: </strong>Trainee radiation dose exposure is higher during the first year of fellowship. Acquisition of optimal performance with fluoroscopy skills can be related to training time. The difference noted between PGY 6 and PGY 7s is likely enhanced for vascular residents (PGY 1-5) and further underscores the importance of early and thorough education in radiation safety for all trainees.</p>","PeriodicalId":17475,"journal":{"name":"Journal of Vascular Surgery","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143674277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to investigate the impact of postoperative DAPT following ET in patients presenting with chronic limb-threatening ischemia (CLTI) in the Vascular Quality Initiative-Medicare-Linked (Vascular Implant Surveillance and Interventional Outcomes Network [VISION]) database.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The study was a multicenter retrospective analysis of prospectively collected VQI-Medicare-Linked data. The VISION database was queried for all ETs performed for infrainguinal occlusive disease between 2011 and 2019. The patients were stratified by discharge antiplatelet regimen (DAPT vs. SAPT). SAPT patients received either aspirin or P2Y12 inhibitors whereas DAPT patients received both. The primary outcome was 1- and 5-year amputation-free survival (AFS). The secondary outcomes included 1- and 5-year overall survival, limb salvage (freedom from major amputation), and freedom from reintervention. Kaplan-Meier survival estimates and Cox regression were used for analysis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The study included two cohorts: SAPT (N=10,086, 41.7%) and DAPT (N=14,081, 58.3%). The patients in SAPT cohort were older than their DAPT counterparts and were more likely to have congestive heart failure and chronic kidney disease. While the patients in the DAPT cohort were more likely to have diabetes and coronary artery disease. In survival analyses, compared to SAPT, 1-year AFS in the DAPT cohort was 67.9% vs. 63.7% (P&lt;.001) and 5- year AFS was 30.4% vs. 24.6% (P&lt;.001). After adjusting for potential confounders, DAPT was associated with reduced hazards of major amputation or death at 1-year (adjusted hazard ratio [aHR]=0.82; 95% confidence interval [CI], 0.75-0.89; P&lt;.001) and 5-year (aHR=0.91; 95% CI, 0.84-0.99; P=0.027). DAPT was also associated with lesser hazards of death (aHR=0.90; 95% CI, 0.81-0.99; P=0.048) and major amputation (aHR=0.86; 95% CI, 0.79-0.93; P&lt;.001) at 1-year but not 5-year. Reintervention was not impacted by the antiplatelet therapy strategy. In our sub-analysis, we found superior five-year overall and amputation-free survivals in patients receiving DAPT compared to aspirin alone and also in patients receiving P2Y12 inhibitor alone compared to aspirin alone. However, the outcomes of DAPT vs. P2Y12 inhibitor alone were not significantly different.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;In this large Medicare-linked national analysis, we found that DAPT is associated with improved AFS up to five years following ET in patients with CLTI compared to SAPT. However, there was no difference between DAPT and P2Y12 inhibitor alone.
