<div><h3>Objective</h3><div>Clinical frailty is associated with reduced long-term survival after fenestrated and branched endovascular aortic repair (F/BEVAR). This study assesses the impact of phenotypic clinical frailty on perioperative outcomes and cause of death following F/BEVAR for thoracoabdominal aortic aneurysm.</div></div><div><h3>Methods</h3><div>Patients who underwent F/BEVAR at a single institution from 2012 to 2024 were identified. The clinical frailty scale (CFS) was used to determine phenotypic frailty. Patients with a preoperative CFS of ≥4 (vulnerable) and a CFS of <4 were compared. We used χ<sup>2</sup> and Fischer exact tests to compare patient demographics, anatomical and operative characteristics, and perioperative outcomes. Fine-Gray analysis was used to compare cause of death between groups. Long-term survival and reintervention were assessed with Kaplan-Meier and Cox regression analyses.</div></div><div><h3>Results</h3><div>We included 233 patients; 60 (25.8%) had a CFS of ≥4 and 173 (74.2%) had a CFS of <4. Patients with a CFS of ≥4 were more likely to have chronic obstructive pulmonary disease (53% vs 27%) and were treated for slightly larger aneurysms (72 mm vs 68 mm; <em>P</em> = .04). There were no differences in symptomatic presentation, aneurysm extent, or operative complexity between patient groups. Additionally, there were no differences in perioperative complications including 30-day mortality, stroke, and spinal cord ischemia. Patients with a CFS of ≥4 had an increased length of hospitalization (11.3 days vs 6.9 days; <em>P</em> < .01) and were less likely to return to preoperative functional status (62.7% vs 86.1%; <em>P</em> < .01). The 3-year all-cause and aortic-related mortality rates were 35.2% and 5.7%, respectively. Patients with a CFS of ≥4 had a lower survival at 1 year (74% vs 89%), 3 years (39% vs 73%), and 5 years (25% vs 56%), compared with patients with a CFS of <4 (<em>P</em> < .01). The most common causes of death among both groups were pulmonary comorbidities (14.0%), oncologic conditions (14.0%), cardiovascular comorbidities (11.2%), and procedure-related complications (11.2%). Patients with a CFS of ≥4 were more likely to die from aortic-related mortality (10.3% vs 5.9%; <em>P</em> = .02), pulmonary comorbidities (15.4 vs 13.2%; <em>P</em> = .04), systemic decline (7.7% vs 1.5%; <em>P</em> = .02), and infection (12.8% vs 7.4%; <em>P</em> = .03). Aortic-related mortality for the entire patient cohort was 2.2% and 5.7% at 1 year and 3 years, respectively. Aortic-related deaths among clinically frail patients were often due to an inability to tolerate further aortic operations (eg, arch repair), and secondary to follow-up nonadherence in patients with a CFS of <4.</div></div><div><h3>Conclusions</h3><div>In an expanded cohort of patients, clinical frailty was associated with lower long-term survival and an increased risk for aortic-related mortality after F/BEVAR for the tr

导读:血管内治疗膝下动脉外周动脉疾病有很高的立即技术失败率,最常见的原因是无法用导丝穿过病变。非对比MRI能够表征斑块组成,并可能识别出血管内穿越失败的高风险患者。本研究评估了一种新的非对比MRI方案在截肢肢模型中识别不可穿透斑块,为临床医生提供了改进患者选择和手术计划的工具。方法:选择行大肢体截肢的CLTI患者行3T非对比MRI检查。评估膝下动脉狭窄或闭塞的病变,并将其定义为硬(>50%钙/胶原)或软(50%钙)。病变也使用TASC II和GLASS系统进行评分。然后,截肢肢体行经皮血管介入治疗,穿过每个病变。主要终点是比较mri定义的硬和软病变的交叉成功率。次要结果包括比较TASC C/D与TASC A/B病变、GLASS III/IV和I/II病变、在轻度钙化硬病变与明显钙化硬病变中交叉的能力、狭窄与完全闭塞。结果:纳入27例患者46例动脉病变。12例(26%)病灶为软病灶,34例(74%)为硬病灶。MRI斑块特征显示出很强的预测价值:与软性病变相比,硬性病变明显不太可能交叉(91% vs 8%, p0.99)。通过闭塞病变和狭窄病变的能力也无显著差异(67% vs 80%, p=0.70)。结论:UTE/SSFP非对比MRI识别出预测交叉失败的关键斑块成分,包括致密胶原蛋白,它在常规成像中不可见,但似乎在独立于钙负荷的交叉失败中起关键作用。这种核磁共振成像方案可以改变决策。它在临床实践中的实施提供了一种基于证据的方法,可以潜在地减少血管内失败,确保先进的交叉装置可用于复杂病变,并指导搭桥手术与血管内治疗的治疗选择。

Objective
In patients with chronic limb-threatening ischemia (CLTI), extra-anatomical bypasses are viable options to establish inflow when aortic cross-clamping necessary for anatomical reconstruction cannot be tolerated or in those with a hostile abdomen. Given their infrequent use, direct comparisons between unilateral axillofemoral bypass (AxFB) vs cross-over femorofemoral bypass (FFB) for CLTI remain scarce. We evaluated postoperative and 5-year outcomes after AxFB vs FFB for CLTI.
Methods
Patients undergoing nonemergent unilateral AxFB and FFB in the Vascular Quality Initiative linked to Medicare claims between 2014 and 2019 were identified, excluding procedures with other concomitant bypasses/interventions. We performed 1:2 (AxFB:FFB) propensity score matching for baseline demographics, comorbidities, urgency, ipsilateral presentation, and contralateral symptoms (rest pain vs ulcer/gangrene), and prior interventions/bypass procedures. Perioperative and 5-year outcomes were analyzed using logistic regression and Cox regression models.
Results
We included 1185 patients (27% AxFB), of whom 224 AxFBs matched with 374 FFBs. After matching, perioperative mortality was comparable between the AxFB and FFB bypass groups (15% vs 10%; P = .12). However, AxFB patients had higher rates of any postoperative complication (30% vs 15%; P < .01) as well as ipsilateral major amputations (below knee, 1.8% vs 0.5%; above knee, 5.4% vs 2.4%; P = .05), in-hospital reintervention (13% vs 7.2%; P = .04), and surgical site infections (5.8% vs 1.6%; P = .01). Patency rates at discharge were similar between the two groups. Postoperative length of stay was higher in the AxFB patients (6.9 ± 5.3 vs 6.2 ± 20; P < .01), and rates for discharge to home were lower (57% vs 68%; P = .07). At 5 years, AxFB was associated with lower rates of 5-year overall survival (41% vs 46%; adjusted hazard ratio [aHR]. 1.3; 95% confidence interval [CI], 1.0-1.7; P = .046), and comparable reintervention free survival (49% vs 45%; aHR, 0.86; 95% CI, 0.59-1.2; P = .40). There was a suggestion of lower major amputation-free survival (69% vs 89%; aHR, 1.7; 95% CI, 0.92-3.1; P = .089), albeit not significantly.
Conclusions
Unilateral AxFB for CLTI was associated with lower 5-year survival rates and similar amputation-free survival and reintervention free-survival rates, alongside similar perioperative mortality and higher postoperative complication rates when compared with FFB. Our data confirm that, among the extra-anatomical bypass options, FFB remains first-line therapy and unilateral AxFB is an alternative option for the treatment of aortoiliac occlusive disease in select CLTI patients with acceptable outcomes.
目的:在慢性肢体威胁缺血(CLTI)患者中,当解剖重建所需的主动脉交叉夹持不能耐受时,或在腹部有敌意的患者中,解剖外旁路是建立血流的可行选择。由于单侧腋股旁路(AxFB)与跨股股旁路(FFB)治疗CLTI的直接比较并不多见。我们评估了AxFB与FFB治疗CLTI的术后和5年预后。方法:确定2014-2019年期间与医疗保险索赔相关的VQI中接受非紧急单侧AxFB和FFB的患者,不包括其他伴随旁路/干预的手术。1:2 (AxFB: FFB)倾向评分匹配基线人口统计学、合并症、急症、同侧表现和对侧症状(静息性疼痛vs溃疡/坏疽)以及既往干预/旁路手术。采用logistic回归和cox回归模型分析围手术期和5年预后。结果:纳入1185例患者(27%为AxFB),其中224例AxFB与374例ffb匹配。配对后,AxFB组和FFB组围手术期死亡率相当(15% vs. 10%; P=.12)。然而,AxFB患者的术后并发症发生率较高(30% vs 15%);结论:与FFB相比,单侧AxFB治疗CLTI的5年生存率较低,无截肢生存率和无再干预生存率相似,围手术期死亡率相似,术后并发症较高。我们的数据证实,在解剖外旁路选择中,FFB仍然是一线治疗,而单侧AxFB是治疗主动脉-髂闭塞性疾病的另一种选择,在选择的CLTI患者中具有可接受的结果。

It is reported that the preprocedural ambulatory status is an important factor of clinical outcomes after endovascular therapy (EVT) in chronic limb-threatening ischemia (CLTI). However, it is not completely understood the impact of preprocedural ambulatory status on clinical outcomes after EVT in patients with CLTI because there are available scarce papers directly comparing among the subgroups according to preprocedural ambulatory status using the data from the real world. This study aimed to evaluate the outcomes by directly comparing among the subgroups based on preprocedural ambulatory status.
Methods
We identified 690 consecutive patients with de novo (which means the first episode of CLTI) CLTI treated with EVT between January 2010 and December 2019 at the New Tokyo Hospital in Japan. The study population was divided into two groups: the ambulatory group (n = 356) and the nonambulatory group (n = 334). In addition, each ambulatory and nonambulatory group was divided into additional two groups. The ambulatory group was divided into ambulatory with and without assistance, and the nonambulatory group was divided into wheel chair users and bedridden patients. The primary end point was major adverse limb event (MALE) at 3 years after EVT. MALE was defined as the composite of all-cause death and major lower limb amputation.
Results
There was an increased risk of MALE in the nonambulatory group (adjusted hazard ratio [HR], 2.36; 95% confidence interval [CI], 1.89-2.95; P < .001). The worse the preprocedural ambulatory status, the higher the risk of MALE for bedridden patients (adjusted HR, 4.42; 95% CI, 3.03-6.46; P < .001), wheel chair users (adjusted HR, 2.57; 95% CI, 1.92-3.44; P < .001), and ambulatory patients with assistance (adjusted HR, 1.49; 95% CI, 1.07-2.08; P = .008) compared with those without assistance.
Conclusions
In patients with CLTI, the worse the preprocedural ambulatory status, the higher the risk of adverse events after EVT for bedridden patients, wheel chair users, and ambulatory patients with assistance compared with those without assistance.

Objective
Lower extremity acute limb ischemia (LE-ALI) is a severe form of peripheral artery disease associated with high morbidity and mortality rates. Thrombus in previously placed stents or grafts may present treatment challenges when compared with treatment of thrombus in native vessels, and data evaluating first-line treatment with mechanical aspiration thrombectomy are lacking. This post hoc analysis of STRIDE (A study of patients with lower extremity acute limb ischemia to remove thrombus with the Indigo Aspiration System) examines outcomes for first-line mechanical aspiration thrombectomy with the Indigo Aspiration System for LE-ALI in patients with either in-stent or in-graft thrombosis as compared with native vessel thrombosis.
Methods
STRIDE was a prospective, single-arm study that enrolled 119 adult patients across 16 sites in the United States and Europe who were treated first-line with the Indigo Aspiration System for LE-ALI. The primary outcome was target limb salvage at 30 days post procedure. Secondary outcomes included device-related serious adverse events, technical success (postprocedure Thrombolysis in Myocardial Infarction flow grades 2/3), and patency at 30 days. Outcomes for the in-stent thrombosis group vs the native vessel thrombosis group, and for the in-graft thrombosis group vs the native vessel thrombosis group, were compared.
Results
Of the 119 STRIDE patients, 29 had in-stent thrombosis, 19 had in-graft thrombosis, and 71 had native vessel thrombosis. For both the in-stent vs native vessel thrombosis and the in-graft vs native vessel thrombosis group comparisons, there were no significant differences for any of the primary or secondary outcomes. Overnight adjunctive thrombolytics use was higher for the in-graft vs native vessel groups (52.6% [10/19]) and 11.3% [8/71], respectively; P < .001). In a combined multivariate Cox model, when adjusted for age and sex among US patients, in-stent thrombosis was associated with time to retreatment within 30 days (hazard ratio, 3.8; 95% confidence interval, 1.1-13.3; P = .040).
Conclusions
Although in-stent and in-graft thrombosis may represent more challenging treatment settings for LE-ALI, high technical success and high target limb salvage rates at 30 days were observed for both groups, similar to the favorable results seen in the native vessel group. Additionally, there were no device-related serious adverse events in either the in-stent or in-graft groups. In-stent thrombosis is associated with an increased risk of retreatment, which is unrelated to the device or procedure and may be expected owing to known complications of stenting. This STRIDE subgroup analysis shows that first-line mechanical aspiration thrombectomy using Indigo is safe and effective for LE-ALI patients in presentations of acute thrombosis in a stent or graft.
目的:下肢急性肢体缺血(LE-ALI)是一种严重的外周动脉疾病,具有很高的发病率和死亡率。与原生血管血栓的治疗相比,先前放置的支架或移植物中的血栓可能存在治疗挑战,并且缺乏评估机械抽吸取栓一线治疗的数据。这项STRIDE研究的事后分析检查了与原生血管血栓形成相比,在支架内或移植物内血栓形成的患者中,使用Indigo抽吸系统对LE-ALI进行一线机械抽吸取栓的结果。方法:STRIDE是一项前瞻性单组研究,在美国和欧洲的16个地点招募了119名成人患者,他们接受了Indigo吸气系统治疗LE-ALI的一线治疗。主要结果是术后30天的目标肢体保留(TLS)。次要结局包括器械相关严重不良事件(sae)、技术成功(术后TIMI血流等级2/3)和30天通畅。比较支架内血栓组与原生血管血栓组的结果,以及支架内血栓组与原生血管血栓组的结果。结果:119例STRIDE患者中,支架内血栓29例,移植物内血栓19例,原生血管血栓71例。对于支架内血管血栓组与原生血管血栓组以及支架内血管血栓组与原生血管血栓组的比较,主要或次要结局均无显著差异。夜间辅助溶栓药物的使用在移植物组高于原生血管组(52.6%(10/19)和11.3%(8/71),差异有统计学意义(P< 0.001)。在一项多因素Cox联合模型中,当对美国患者的年龄和性别进行调整后,支架内血栓形成与30天内再治疗的时间相关(HR=3.8,95% CI 1.1-13.3, P = 0.040)。结论:尽管支架内和移植物内血栓形成可能是LE-ALI的更具挑战性的治疗环境,但两组在30天内均观察到高技术成功率和高TLS,与原生血管组的良好结果相似。此外,支架内组和移植物组均未发生与器械相关的sae。支架内血栓形成与再治疗的风险增加有关,这与设备或程序无关,并且可能由于已知的支架并发症而预期。STRIDE亚组分析显示,对于出现支架或移植物急性血栓形成的LE-ALI患者,使用Indigo进行一线机械抽吸取栓是安全有效的。
