Background: We investigated the safety and efficacy of rivaroxaban as routine thromboprophylaxis after endovenous thermal ablation (EVTA). Patients and methods: Adhering to the PRISMA 2020 guidelines, we conducted a systematic review for studies published up to April 2024. Primary endpoints included endovenous heat-induced thrombosis (EHIT) class ≥ II, deep vein thrombosis (DVT), major and minor bleeding and the composite endpoint of major thromboembolic complications including any incidents of EHIT ≥ III, DVT or pulmonary embolism (PE). Results: Eight retrospective case series, encompassing 1666 patients, and 2049 truncal veins were included. The pooled EHIT ≥ II, DVT, and major thromboembolic complications estimates were 0.73% (95% CI: 0.37-1.42), 0.51% (95% CI: 0.22-1.17) and 0.71% (95% CI: 0.27-1.89). The crude and pooled major and minor bleeding estimates were 0% (0/885) and 2.60% (95% CI: 1.05-6.33). The pooled early truncal and great saphenous vein (GSV) occlusion outcomes were 99.03% (95% CI: 96.88-99.70) and 98.74% (95% CI: 92.07-99.81). The pooled and crude superficial thrombophlebitis and PE estimates were 2.86% (95% CI: 0.88-8.89) and 0% (0/579). While the comparative analysis between rivaroxaban and low molecular weight heparins (LMWH)/fondaparinux displayed improved outcomes favouring rivaroxaban in terms of DVT, risk ratio (RR), 0.60 (95% CI: 0.12-3.07) and truncal occlusion, odds ratio (OR), 1.43 (95% CI: 0.31-6.55) outcomes did not reach statistical significance. Meta-regression analysis including rivaroxaban treatment durations spanning from three to ten days displayed a negative association between duration of treatment and both truncal, (β = -0.4740, p<0.01) and GSV, (β = -0.4583, p<0.01) occlusion in the early pos-operative period. Conclusions: The results of this review underscore the potential safety of rivaroxaban as thromboprophylaxis in the context of endovenous thermal ablation. The observed inverse relationship between anticoagulation duration and occlusion outcomes should be interpreted with caution, highlighting the need for further research.

Background: Percutaneous superficial femoral interventions remain the preferred method of treatment for superficial femoral artery (SFA) disease. Nevertheless, long term restenosis continues to be a major limitation of percutaneous interventions. In this context, the objective of this study is to compare the efficacies of CHA2DS2-VASc, CHA2DS2-VASc-HS, ATRIA, ATRIA-HSV, and HATCH risk scoring systems in predicting long-term (5 years) restenosis due to percutaneous interventions to the superficial femoral artery. Patients and methods: The sample of this retrospective study consisted of 545 peripheral artery disease (PAD) patients with a percutaneous intervention to the SFA. Of these patients, 362 and 183 were included in the group of PAD patients without long-term (5 years) SFA restenosis (Group 1) and in the group of PAD patients with long-term SFA restenosis (Group 2). The efficacies of CHA2DS2-VASc, CHA2DS2-VASc-HS, ATRIA, ATRIA-HSV, and HATCH risk scoring systems in predicting the development of long-term SFA restenosis were comparatively analyzed. Results: CHA2DS2-VASc, CHA2DS2-VASc-HS, ATRIA, ATRIA-HSV, and HATCH risk scores all increased with long-term SFA restenosis. The receiver operating characteristic (ROC) curve analysis revealed that all five risk scoring systems successfully predicted long-term SFA restenosis, whereas the paired ROC curve analysis revealed that CHA2DS2-VASc-HS scores of >4 had the best prognostic power in predicting long term SFA restenosis. Conclusions: The study findings indicated that the CHA2DS2-VASc-HS score was an independent predictor of the development of SFA restenosis. The CHA2DS2-VASc-HS risk scoring system, which is the modified version of CHA2DS2-VASc, outperformed the CHA2DS2-VASc, HATCH, ATRIA, and ATRIA-HSV, the modified version of ATRIA, risk scoring systems in predicting long-term (5 years) SFA restenosis.

Background: Pulmonary embolism (PE) can result in high mortality. Early risk stratification and treatment are critical for individualized management. In patients with intermediate-high-risk (IHR) PE, guidelines recommend to consider a percutaneous catheter-directed treatment (CDT). While different techniques are available, comparisons between treatments regarding right ventricular (RV) function and outcome are still scarce. This study aimed to compare changes in RV function as well as outcomes in patients with IHR PE after CDT with ultrasound-assisted thrombolysis (USAT) as compared to large-bore mechanical thrombectomy (MT). Patients and methods: This is a retrospective, single-center study in IHR PE, diagnosed in accordance with the ESC Guidelines. All patients underwent a CDT either with USAT (EKOS, Boston Scientific) or MT (FlowTriever System, Inari). Right heart function (RV/LV ratio, TAPSE) was assessed via transthoracic echocardiography before and after CDT as well as interventional characteristics and postinterventional hospital stay were compared. Results: From June 2022 to April 2024, 26 patients (35% female; aged 61.2±15.2 years) were diagnosed with IHR PE and underwent CDT. 14 patients (53.8%) were treated with USAT and 12 patients (46.2%) with MT. The mean procedural time was 40.4±19.8 minutes for USAT and 104±32.2 minutes for MT. RV/LV ratio was improved in both groups (change from baseline USAT -0.48±0.25; MT -0.36±0.13). TAPSE increased by 6.95±3.7 mm in USAT and by 9.8±4.6 mm in MT. Major bleeding (defined as BARC ≥ 3a) occurred only in three patients of the USAT group. The 90-day mortality rate was 0% in both groups. Conclusions: In patients with IHR PE both USAT and MT lead to an improved RV function without mortality within 90 days. Further randomized data have to discriminate the differential impact of novel tools for the treatment of IHR PE.

Background: Although venous stent placement is an established treatment for patients with deep vein thrombosis (DVT) and post-thrombotic syndrome (PTS), stent patency rate may be as low as 80% at 12 months. Treatment of stent occlusion requires the removal of a large amount of fresh or organized thrombus from stents with a diameter of 12-20 mm. The feasibility of large-bore rotational thrombectomy in combination with angioplasty to treat thrombosed venous iliofemoral or inferior vena cava stents has not been investigated yet. Patients and methods: Between May 2023 and June 2024, 12 patients (15 limbs) with symptomatic venous stent occlusions were treated at our institution with the 10-French Rotarex™ thrombectomy device and completed 3-month follow-up by Duplex ultrasound. The primary outcome was primary patency at 90 days after thrombectomy of stent occlusion. Safety outcomes included device-related complications, bleeding, and death. Results: Median age was 41 years, 75% were women. At the index procedure, 10 (83%) patients presented with PTS and two (17%) with acute DVT. Median time from index procedure to re-intervention was 1125 (Q1-Q3: 897-2297) days and from symptom onset to re-intervention 39 (Q1-Q3: 8-186) days. Technical success of re-intervention was achieved in all cases, and bail-out stent-in-stent placement was not required in 5 (33%) limbs. The primary patency rate at 90 days was 86.7% (95% CI: 71.0-100.0). Two (17%) patients experienced recurrent stent thrombosis and were managed conservatively. Peri-interventional minor bleeding occurred in two (17%) patients. There were no device-related complications, major bleeding, or deaths. Conclusions: Large-bore rotational thrombectomy appears to be a feasible strategy to treat iliofemoral and inferior vena cava stent thrombosis, achieving acceptable short-term patency without major adverse events.

Background: Arteriovenous grafts (AVG) can be the only bailout solution for patients who require kidney replacement therapy but are unsuitable for arteriovenous fistula (AVF) creation. Currently, high-level evidence on the effectiveness and safety of antithrombotic therapy in AVG patients is scarce. Materials and methods: Following the PICO (patient; intervention; comparator; outcome) model and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a data search of the English literature in PubMed, SCOPUS, Central Cochrane was conducted, until March 1st, 2023 (PROSPERO Protocol Number: CRD42023401785). Studies on humans with an AVG receiving any kind of antithrombotic medication, reporting on primary and secondary patency rates, and bleeding complications were included. Due to data heterogeneity, a descriptive report of the outcomes was undertaken. Results: Twelve studies, including 22,436 patients with end-stage renal disease (ESRD) and AVG were included, with patient recruitment spanning over a 41-year time-period (1982-2023). Antithrombotic factors included acetylsalicylic acid (ASA), clopidogrel, dipyridamole, warfarin, unfractioned heparin (UFH), and direct oral anticoagulants (DOACs). Ten studies reported on primary patency rates, and two on secondary patency rates. Primary and secondary patency rates (PPR, SPR) were reported better in four studies, similar in three and worse in one study, regarding patients receiving any kind of antiplatelet therapy. Anticoagulation therapy was not associated with increased PPR or SPR, except for one study on apixaban. Patients receiving single or combined antiplatelets versus patients receiving no treatment presented higher bleeding risk in two studies and similar bleeding risk in three studies. Anticoagulation therapy, excluding apixaban, was associated with higher bleeding risk in three studies, when compared to no anticoagulation. Conclusions: Data derived from the current literature were equivocal regarding the use of antiplatelet treatment in patients with AVG. Studies on anticoagulation therapy are confined. Randomized trials with confounder stratification remain crucial for robust long-term data.
背景:对于需要肾脏替代治疗但不适合制造动静脉瘘的患者,动静脉移植(AVG)可能是唯一的救助方案。目前,关于AVG患者抗血栓治疗的有效性和安全性的高水平证据很少。材料和方法:PICO(患者;干预;比较器;在PubMed, SCOPUS, Central Cochrane的英文文献中进行数据检索,直到2023年3月1日(PROSPERO协议号:CRD42023401785)。包括对接受抗血栓药物治疗的房颤患者的研究,报告原发性和继发性通畅率,以及出血并发症。由于数据异质性,对结果进行了描述性报告。结果:纳入了12项研究,包括22,436例终末期肾病(ESRD)和AVG患者,患者招募时间跨度为41年(1982-2023)。抗血栓因子包括乙酰水杨酸(ASA)、氯吡格雷、双嘧达莫、华法林、未分离肝素(UFH)和直接口服抗凝剂(DOACs)。10项研究报道了原发性通畅率,2项研究报道了继发性通畅率。在接受任何抗血小板治疗的患者中,有4项研究报告原发性和继发性通畅率(PPR, SPR)较好,3项研究报告相似,1项研究报告较差。除了一项关于阿哌沙班的研究外,抗凝治疗与PPR或SPR的增加无关。在两项研究中,接受单一或联合抗血小板药物治疗的患者与未接受治疗的患者相比,出血风险更高,在三项研究中,出血风险相似。在三项研究中,抗凝治疗(不包括阿哌沙班)与不进行抗凝治疗相比,出血风险更高。结论:目前文献中关于AVG患者使用抗血小板治疗的数据是模棱两可的,关于抗凝治疗的研究是有限的。混杂因素分层的随机试验对于获得可靠的长期数据仍然至关重要。

Background: Infrapopliteal endovascular interventions (EVT) strategies in diabetic patients are still in debate because the lesions are more likely to be diffuse with a different pattern of collateral arteries ranging from reduced to normal caliber. The aim of this all-comers study was to analyse the outcome of two different infrapopliteal EVT strategies (Group I: angiosome-based direct revascularization - DR vs. Group II: complete (direct + indirect) revascularization strategy - CR) in diabetic patients with chronic limb-threatening ischemia (CLTI) in 2 time-periods. Furthermore we analysed the outcome if DR or CR failed and only indirect revascularization (IR) or no revascularization was possible. Both groups were differentiated in patients with collaterals, defined as an intact pedal arch (immediate or after pedal PTA). Patients and methods: The database includes 91 consecutive EVT with two intrapopliteal interventional strategies performed in 68 diabetic patients (pts. 24 female, 44 male, mean age 73±10 years) between 2013-2016 and 2017-2022. Positive clinical outcome was defined as wound healing with or w/o minor amputation, combined with a symptom improvement to Rutherford category 0 or 1 after 6 months. The clinical outcome proportions were compared using the Fisher's exact test. Results: Successful DR (59%) and successful CR (47%) strategy demonstrated a similar positive clinical outcome (92.6% vs. 90.5%; p=0.594). Indirect revascularization (Group I: 26%; Group II: 44%) showed a significantly lower positive outcome in comparison to a successful DR as well as CR strategy (33.3% vs. 92.6%, p=0.0003; 40% vs 90.5%, p=0.001). IR outcome improved by the presence of collaterals (66.7% vs. 30.8%). Conclusions: In case of successful intervention, both strategies (DR and CR) yielded a similarly high proportion of positive clinical outcome. The role of collaterals and the pedal arch on the clinical outcome are important in patients in whom only IR was possible.
背景:糖尿病患者的髂腹下血管内介入治疗(EVT)策略仍存在争议,因为病变更有可能是弥漫性的,侧支动脉的形态也不尽相同,有的直径缩小,有的直径正常。本研究的目的是分析两种不同的腘窝下EVT策略(第一组:基于血管造影剂的直接血管再通--DR与第二组:完全(直接+间接)血管再通策略--CR)在两个时间段内对患有慢性肢体缺血(CLTI)的糖尿病患者的治疗效果。此外,我们还分析了如果 DR 或 CR 失败,只能进行间接血管再通(IR)或无法进行血管再通的结果。两组患者均有肢体侧支,即完整的足弓(立即或在足弓 PTA 后)。患者和方法:数据库包括2013-2016年和2017-2022年期间为68名糖尿病患者(患者24名女性,44名男性,平均年龄(73±10)岁)实施的91例连续EVT,采用两种髂内介入策略。阳性临床结果定义为伤口愈合,伴有或不伴有轻微截肢,6个月后症状改善至卢瑟福0类或1类。临床结果比例的比较采用费雪精确检验。结果如下DR成功率(59%)和CR成功率(47%)显示出相似的积极临床结果(92.6% vs. 90.5%;P=0.594)。与成功的 DR 和 CR 策略相比,间接血运重建(第一组:26%;第二组:44%)的阳性结果明显较低(33.3% vs. 92.6%,p=0.0003;40% vs. 90.5%,p=0.001)。红外预后因存在侧支而有所改善(66.7% 对 30.8%)。结论在干预成功的情况下,两种策略(DR 和 CR)都能产生类似高比例的积极临床结果。对于只能进行 IR 治疗的患者,瓣膜和足弓对临床结果的影响非常重要。

Background: To evaluate the impact of polypharmacy, defined as the concurrent use of five or more medications, on the clinical outcomes of patients undergoing revascularisation for symptomatic peripheral arterial disease (PAD). Patients and methods: This is a retrospective analysis of consecutive PAD patients treated by surgical, endovascular or hybrid therapy in a tertiary center between January 2017 and December 2017. The composite of amputation and/or death (amputation-free survival; AFS) was the primary endpoint. Mortality, major limb amputation, risk for Major Cardio-Cerobro-vascular Events (MACCE) and re-intervention during follow-up were additionally analyzed. Results: A total of 560 patients (369 male, 66%) were included. Mean age was 72.43 ± 38.67, while the main indication for treatment was lifestyle limiting claudication (330 patients, 59%). Most patients (434, 78%) were treated with endovascular means, and the commonest anatomical site of intervention was the femoropopliteal arterial segment (449 patients, 80%). A total of 409 (73%) met the criteria for polypharmacy. Cox regression analysis showed that polypharmacy was an independent predictor of death (exp: 4.72, p=0.008), MACCE (exp: 2.82, p=0.001), re-intervention (exp 1.51, p=0.0016) and of the composite outcome of AFS (exp: 3.46, p=0.021) but not of major amputation (exp: 1.26, p=0.686). Propensity-score matching analysis showed that even when controlling for comorbidity and procedural characteristics, polypharmacy is associated with a higher risk of cardiovascular death (p<0.001), MACCE (p<0.001), and re-intervention (p=0.001). Conclusions: In this study, polypharmacy was associated with unfavourable clinical outcomes for patients undergoing revascularisation for symptomatic PAD, without influencing the risk for major limb amputation.

Background: Thromboangiitis obliterans (TAO) is a rare but threatening disease associated with significant morbidity and mortality. The pathophysiology is poorly understood, the diagnosis is often obscure and causal treatment options are limited. In the current study, we aimed to identify distinct TAO patient clusters that differed in clinical presentation and prognosis. Patients and methods: We retrospectively analysed a cohort of 48 patients with the working diagnosis TAO who were assessed for clinical presentation at hospital admission. We applied hierarchical clustering to divide patients into clinically meaningful subgroups. Results: Patients were followed-up for a median of 95 months. We found that cluster analyses including a variety of demographic and diagnostic parameters were valuable to identify patient subgroups with similar clinical presentation, but with different clinical course of the disease, including the individual risk for mortality and major amputation. Patients treated with statins showed a significantly better survival, which may allow us to hypothesize that a conventional secondary prevention strategy, which is recommended for atherosclerotic artery diseases, may be of benefit also in patients that present with TAO. Conclusions: The current data may help to develop strategies to identify high-risk TAO patients. Furthermore, statins may serve as a readily available therapeutic option to this rare but serious disease.
