Outcomes of covered vs bare metal stents for the treatment of aortoiliac occlusive disease.

Objective: We retrospectively compared the clinical outcomes of self-expanding covered stents (CSs) and bare metal stents (BMSs) in the treatment of aortoiliac occlusive disease (AIOD) at a single center between 2016 and 2022.

Methods: All patients with AIOD receiving endovascular therapy at a single center from January 2016 to October 2022 were continuously analyzed, including patients with lesions of all classes according to the Trans-Atlantic Inter-Society Consensus II (TASC-II). Relevant clinical and baseline data were collected, and propensity score matching was performed to compare CSs and BMSs in terms of baseline characteristics, surgical factors, 30-day outcomes, 5-year primary patency, and limb salvage.

A Bayesian network meta-analysis for acute thrombosis after lower extremity artery endovascular treatment.

Background: Various endovascular treatment devices have been widely used in the lower extremity arterial disease (LEAD). Their patency efficiency for target lesions has been well studied and reported. Comparison of the risk of acute thrombosis events between the different endovascular treatment devices is unclear.

Perfusion pressure of elastase impacts the formation ratio and diameters of abdominal aortic aneurysms in rats.

Intra-arterial perfusion with elastase is a common method used to create abdominal aortic aneurysms (AAA) models. The present study aimed to explore the impact of porcine pancreatic elastase (PPE) perfusion pressure on the morphology of abdominal aortic aneurysms. A total of 40 male Sprague Dawley rats were randomized into four groups.

Midterm Outcomes of Kissing Covered Self-Expanding Stents for Reconstruction of Complex Aortoiliac Occlusive Disease.

Background: We sought to investigate the midterm results of kissing self-expanding covered stents (SECSs) for the reconstruction of aortic bifurcation in complex aortoiliac occlusive disease.

Methods: Data of consecutive patients who had undergone endovascular treatment for aortoiliac occlusive disease were screened. Only patients with TransAtlantic Inter-Society Consensus (TASC) class C and D lesions treated by bilateral iliac kissing stents (KSs) were included.

Impact of residual stenosis on clinical outcomes when performing carotid artery stenting without postdilation.

Objective: Many centers consider postdilation if the final angiography after carotid artery stenting (CAS) shows residual stenosis of >30% to 40%. Postdilation has been demonstrated to potentially increase the risk of developing neurologic events. This study aimed to investigate the safety of CAS without postdilation regardless of the degree of residual stenosis.

Perioperative Inflammatory Status Predicts Mid-Term Outcomes in Patients Undergoing Femoropopliteal Paclitaxel-Coated Balloon Angioplasty.

Background: To evaluate the association of perioperative inflammatory status, as determined using the neutrophil-to-lymphocyte ratio (NLR) and high-sensitivity C-reactive protein (hs-CRP) level, with the efficacy of femoropopliteal paclitaxel-coated balloon (PCB) angioplasty.

Methods: The data of 122 patients (138 limbs) were retrospectively analyzed (median follow-up time, 21 months). The pre- and postoperative NLRs and hs-CRP levels were evaluated to determine their predictive value for mid-term primary patency and clinically driven target lesion revascularization (CD-TLR) during follow-up.

Dose-Response Relationship Between Physical Activity and the Incidence of Peripheral Artery Disease in General Population: Insights From the National Health and Nutrition Examination Survey 1999-2004.

A low ABI, ≦0.9, indicates peripheral artery disease (PAD) and physical activity (PA) represents an important non-surgical treatment for patients with PAD. However, as for the general population, the associations between PA, PAD, and their mutual dependence are not well-defined.

A Novel Sirolimus-eluting Biodegradable Magnesium-based Alloy Scaffold: Six-month Results In Porcine Peripheral Arteries.

Purpose: Magnesium-based alloy scaffold is a promising biodegradable stent due to its intrinsic mechanical performance and biocompatibility. Based on our preliminary experiments, we designed a novel sirolimus-eluting magnesium-based alloy scaffold. This work aimed to assess its safety and degradation performance in vivo.

Perioperative baseline -blockers: An independent protective factor for post-carotid endarterectomy hypertension.

Objective: Post-carotid endarterectomy hypertension is a well-recognized phenomenon closely related to surgical complications. This study aimed to determine whether different kinds of perioperative antihypertensive drugs had a protective effect on post-carotid endarterectomy hypertension and influence on intraoperative hemodynamics.

Method: We retrospectively investigated 102 carotid stenosis patients who underwent conventional endarterectomy with a perioperative baseline antihypertensive regimen.

Chemokine-like factor 1 (CKLF1) aggravates neointimal hyperplasia through activating the NF-κB /VCAM-1 pathway.

Neointimal hyperplasia (NIH) is a complicated inflammatory process contributing to vascular restenosis. The present study aimed to explore whether chemokine-like factor 1 (CKLF1) aggravates NIH via the nuclear factor-kappa B (NF-κB)/vascular cell adhesion molecule-1 (VCAM-1) pathway. We found the expression of CKLF1 and VCAM-1 significantly increased in human carotid plaques compared to the control.

Outcomes of Total Aortoiliac Revascularization for TASC-II C&D Lesion with Kissing Self-Expanding Covered Stents.

Background: The endovascular approach has been widely used for aortoiliac occlusive disease (AIOD), especially for aortic bifurcation and iliac artery Trans-Atlantic Inter-Society Consensus II (TASC-II) A and B lesions. However, the outcomes of self-expanding covered stents (SECSs) for extensive aortoiliac lesion remain unclear. This study aimed to assess the short-term patency of kissing covered stents for the revascularization of aortoiliac TASC-II C and D diseases.
