Stenting versus balloon angioplasty alone in patients with below-the-knee disease: A propensity score-matched analysis.

ABSTRACT: Percutaneous transluminal angioplasty (PTA) is considered an effective treatment in patients with critical limb ischemia (CLI). However, the long-term durability of below-the-knee (BTK) PTA is known to be limited. This study sought to compare the 1-year clinical outcomes following stenting versus balloon angioplasty alone in BTK lesions. This study included 357 consecutive patients (400 limbs, 697 lesions) with BTK lesions who underwent PTA from September 2010 to December 2016. All enrolled patients were treated either by stenting (stent group; 111 limbs of 102 patients) or plain old balloon angioplasty (POBA group; 289 limbs of 255 patients). Stent group includes both primary and provisional stenting. Angiographic outcomes, procedural success, complications, and clinical outcomes were compared between the two groups up to 1 year. After propensity score matching (PSM) analysis, 56 pairs were generated, and the baseline and angiographic characteristics were balanced. The procedural success and complications were similar between the two groups; however, the incidence of procedure-related perforation was higher in the POBA group than in the stenting group [5(11.9%) vs.1 (0.9%), P = 0.009]. Six- to 9-month computed tomography or angiographic follow-up showed similar incidences of binary restenosis, primary patency, and secondary patency. In the 1-year clinical follow-up, there were similar incidences of individual hard endpoints, including mortality, myocardial infarction, limb salvage, and amputation rate, with the exception of target extremity revascularization (TER), which tended to be higher in the stenting group than in the POBA group [21 (20.8%) vs. 11 (10.9%), P = 0.054]. Although there was a trend toward a higher incidence of TER risk in the stenting group, stent implantation, particularly in bail-out stenting seemed to have acceptable 1-year safety and efficacy compared to POBA alone in patients undergoing BTK PTA.

Project description:PurposeLower limb alignment is crucial in total knee arthroplasty (TKA). Previous studies have shown that robotics and personalized three-dimensional (3D) preoperative planning could improve postoperative alignment accuracy compared with conventional TKA, but comparison between the above two techniques has never been reported. The authors hypothesized that robotics may be superior to personalized 3D preoperative planning in terms of postoperative alignment in primary TKA, with similar patient-reported outcome measures (PROMs) but higher cost and longer operative time.MethodsA consecutive series of patients who received TKA in our center from September 2020 to January 2021 were enrolled retrospectively. After 1:2 matching, 52 and 104 patients were included and divided into study group for robotics and control group for personalized 3D preoperative planning, respectively. Multiple postoperative alignment angles were measured, and clinical features such as operation and tourniquet time, length of hospital stay and hemoglobin (Hb) were recorded. Knee Society Score (KSS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were used to evaluate clinical results.ResultsCompared with control group, robotics group had significantly lower frontal femoral component angle (FFC) and frontal tibial component angle (FTC) absolute deviation (P < 0.05). It also had less outliers in hip-knee-ankle angle (HKA), FTC, lateral femoral component angle (LFC) and lateral tibial component angle (LTC) (P < 0.05). Hb loss of robotics group was significantly lower than control group (P < 0.001), while the operation and tourniquet time were longer (P < 0.001). There was no significant difference in KSS and WOMAC scores between two groups.ConclusionCompared with control group, patients in robotics group had significantly less malalignment, malposition, Hb loss, but similar PROMs. The operations in robotics group spent longer operation time and cost more compared with control group.Trial registrationThe Chinese Clinical Trial Registry, ChiCTR2000036235.

Project description:AimsWe performed a meta-analysis to indirectly compare the treatment effectiveness of balloon angioplasty and stenting for patients with intracranial arterial stenosis.MethodsLiterature searches were performed in well-known databases to identify eligible studies published before January 04, 2021. The incidence of restenosis, transient ischemic attack (TIA), stroke, death, and dissection after balloon angioplasty or stenting were pooled. An indirect comparison of balloon angioplasty vs. stenting was performed, and the ratios of incidence (RIs) with 95% confidence intervals (CIs) were calculated using the random-effects model.Results120 studies that recruited 10,107 patients with intracranial arterial stenosis were included. The pooled incidence of restenosis after balloon angioplasty and stenting were 13% (95%CI: 8-17%) and 11% (95%CI: 9-13%), respectively, with no significant difference between them (RI: 1.18; 95%CI: 0.78-1.80; P = 0.435). Moreover, the pooled incidence of TIA after balloon angioplasty and stenting was 3% (95%CI: 0-6%) and 4% (95%CI: 3%-5%), and no significant difference was observed (RI: 0.75; 95%CI: 0.01-58.53; P = 0.897). The pooled incidence of stroke after balloon angioplasty and stenting was 7% (95%CI: 5-9%) and 8% (95%CI: 7-9%), respectively, and the difference between groups was found to be statistically insignificant (RI: 0.88; 95%CI: 0.64-1.20; P = 0.413). Additionally, the pooled incidence of death after balloon angioplasty and stenting was 2% (95%CI: 1-4%) and 2% (95%CI: 1-2%), with no significant difference between groups (RI: 1.00; 95%CI: 0.44-2.27; P = 1.000). Finally, the pooled incidence of dissection after balloon angioplasty and stenting was 13% (95%CI: 5-22%) and 3% (95%CI: 2-5%), respectively, and balloon angioplasty was associated with a higher risk of dissection than that with stenting for patients with intracranial arterial stenosis (RI: 4.33; 95%CI: 1.81-10.35; P = 0.001).ConclusionThis study found that the treatment effectiveness of balloon angioplasty and stenting were similar for patients with symptomatic intracranial arterial stenosis.

Project description:ObjectivePrimary nitinol stenting (PNS) and drug-coated balloon (DCB) angioplasty are two of the most common endovascular interventions for femoropopliteal atherosclerotic disease. Although many prospective randomized controlled trials have compared PNS or DCB with plain balloon angioplasty (POBA), no studies have directly compared PNS against DCB therapy. The purpose of this network meta-analysis is to determine whether there is a significant difference in outcomes between PNS and DCB.MethodsThe primary outcome measure was binary restenosis, the secondary outcome measures were target lesion revascularization (TLR) and change in the ankle-brachial index (ABI). Outcomes were evaluated at 6, 12, and 24 months. A literature review identified all randomized controlled trials published before March 2020 that compared DCB with POBA or PNS with POBA in the treatment of native atherosclerotic lesions of the femoropopliteal artery. Studies were excluded if they contained in-stent stenosis or tibial artery disease that could not be delineated out in a subgroup analysis. Network meta-analysis was performed using the network and mvmeta commands in STATA 14.ResultsTwenty-seven publications covering 19 trials were identified; 8 trials compared PNS with POBA and 11 trials compared DCB with POBA. The odds of freedom from binary restenosis for patients treated with DCB compared with PNS at 6 months was 1.19 (95% confidence interval [CI], 0.63-2.22), at 12 months was 1.67 (95% CI, 1.04-2.68), and at 24 months was 1.36 (95% CI, 0.78-2.37). The odds of freedom from TLR for patients treated with DCB compared with PNS at 6 months was 0.66 (95% CI, 0.12-3.80), at 12 months was 1.89 (95% CI, 1.04-3.45), and at 24 months was 1.68 (95% CI, 0.82-3.44). The mean increase in ABI for patients treated with PNS compared with DCB at 6 months was 0.06 higher (95% CI, -0.03 to 0.15), at 12 months was 0.05 higher (95% CI, 0.00-0.09), and at 24 months was 0.07 higher (95% CI, -0.01 to 0.14).ConclusionsBoth DCB and PNS demonstrated a lower rate of binary restenosis compared with POBA at the 6-, 12-, and 24-month timepoints. When comparing DCB with PNS through network meta-analysis, DCB had a statistically lower rate of a binary restenosis and TLR at the 12-month timepoint. This network meta-analysis demonstrates that both DCB and PNS are superior to POBA, and that PNS is a satisfactory substitute for DCB when paclitaxel is not desirable.

Project description:ObjectivesThe aim of this study is to compare the postoperative complications, perioperative course, and survival among patients from the multicentric Spanish Video-assisted Thoracic Surgery Group database who received video-assisted thoracic surgery lobectomy or video-assisted thoracic surgery anatomic segmentectomy.MethodsFrom December 2016 to March 2018, a total of 2250 patients were collected from 33 centers. Overall analysis (video-assisted thoracic surgery lobectomy = 2070; video-assisted thoracic surgery anatomic segmentectomy = 180) and propensity score-matched adjusted analysis (video-assisted thoracic surgery lobectomy = 97; video-assisted thoracic surgery anatomic segmentectomy = 97) were performed to compare postoperative results. Kaplan-Meier and competing risks method were used to compare survival.ResultsIn the overall analysis, video-assisted thoracic surgery anatomic segmentectomy showed a lower incidence of respiratory complications (relative risk, 0.56; confidence interval, 0.37-0.83; P = .002), lower postoperative prolonged air leak (relative risk, 0.42; 95% confidence interval, 0.23-0.78; P = .003), and shorter median postoperative stay (4.8 vs 6.2 days; P = .004) than video-assisted thoracic surgery lobectomy. After propensity score-matched analysis, prolonged air leak remained significantly lower in video-assisted thoracic surgery anatomic segmentectomy (relative risk, 0.33; 95% confidence interval, 0.12-0.89; P = .02). Kaplan-Meier and competing risk curves showed no differences during the 3-year follow-up (median follow-up in months: 24.4; interquartile range, 20.8-28.3) in terms of overall survival (hazard ratio, 0.73; 95% confidence interval, 0.45-1.7; P = .2), tumor progression-related mortality (subdistribution hazard ratio, 0.41; 95% confidence interval, 0.11-1.57; P = .2), and disease-free survival (subdistribution hazard ratio, 0.73; 95% confidence interval, 0.35-1.51; P = .4) between groups.ConclusionsVideo-assisted thoracic surgery segmentectomy showed results similar to lobectomy in terms of postoperative outcomes and midterm survival. In addition, a lower incidence of prolonged air leak was found in patients who underwent video-assisted thoracic surgery anatomic segmentectomy.

Project description:BackgroundPeripheral arterial disease (PAD) is a common and highly morbid disease. Although there have been recent advancements in the endovascular modalities to treat PAD, comparisons of these strategies, especially in the popliteal region, remain underinvestigated. The objective of this study was to compare midterm outcomes in patients with PAD undergoing treatment with both novel and SS compared with drug-coated balloon (DCB) angioplasty.MethodsAll patients at a multi-institution health system treated for PAD in the popliteal region from 2011 to 2019 were identified. Presenting features, operative details, and outcomes were included in the analysis. Patients who underwent popliteal revascularization with stents were compared with DCB. SS were compared separately with novel dedicated stents. Two-year primary patency was the primary outcome.ResultsWe included 408 patients (72.7 ± 11.8 years old; 57.1% men) in the analysis. There were 221 (54.7%) patients who underwent popliteal stenting and 187 (45.3%) who underwent popliteal DCB. There were high rates of tissue loss in both groups (57.9% vs 50.8%; P = .14). Stented patients had longer lesions (112.4 ± 3.2 vs 100.2 ± 5.8 mm; P = .03) and higher rates of concomitant superficial femoral artery treatment (88.2% vs 39.6%; P < .01). Chronic total occlusions accounted for the majority of lesions treated (stent 62.4%, DCB 64.2%). Perioperative complications were similar between groups. Primary patency for the stented group was higher at two years than the DCB group (61.0% vs 46.1%; P = .03). When evaluating stented patients only, SS had higher 2-year patency than novel stents in the popliteal segment (69.6% vs 51.4%; P = .04). On multivariable analysis, stenosis, as opposed to chronic total occlusion, was associated with improved patency (hazard ratio, 0.49; 95% confidence interval, 0.25-0.96; P = .04), whereas novel stents were associated with worse primary patency (hazard ratio, 2.01; 95% confidence interval, 1.09-3.73; P = .03).ConclusionsIn a population of patients with severe vascular disease, stents do not have inferior patency and limb salvage rates compared with DCB angioplasty when treating the popliteal region. For patients with advanced vascular disease, and especially tissue loss, stents and DCB are both beneficial when treating popliteal lesions.
