Hemodynamic analysis of thoracic endovascular aortic repair with left subclavian artery reconstructed by chimney stent.

Objectives: The purpose of this study was to investigate the hemodynamic consequences of thoracic endovascular aortic repair which reconstructed left subclavian artery by chimney stent (ch-TEVAR).

Methods: Two patients who underwent thoracic endovascular aortic repair (TEVAR) and left subclavian artery (LSA) reconstruction using chimney stents were selected. Preoperative and postoperative CTA images were collected to reconstruct hemodynamic models for comparing and analyzing blood pressure, blood flow velocity, and wall shear stress in the aortic arch and its major branches.

Use of the Amplatzer vascular plug to treat carotid body tumors extending to the skull base.

Background: Carotid body tumors extending to the skull base are hypervascular tumors which are difficult to access using a traditional lateral cervical approach. Preoperative embolization can reduce intraoperative blood loss.

Case Presentation: We report two patients with a carotid body tumor extending to the skull base who underwent preoperative embolization of the external carotid artery using an Amplatzer vascular plug.

Optimized Intermediates Adsorption Configuration on Co-Doped FeP@NiP Heterojunction Interface for Enhanced Electrocatalytic Nitrate-To-Ammonia Conversion.

The extraction of ammonia (NH) through electrocatalytic nitrate reduction reaction (NO RR) represents a sustainable avenue in NH generation and utilization. However, the catalytic efficiency of the NO RR is hindered by the sluggish kinetics. This study first theoretically found that phosphide-based heterostructure can alter the adsorption structure of intermediates in the nitrate-to-ammonia process, thereby achieving precise regulation of the energy barrier in the rate-determining step.

Application of the Double Series Filter Technique for the Treatment of Acute Inferior Vena Cava Filter-Mediated Thrombosis.

Background: In this study, we examined the safety and effectiveness of removing inferior vena cava (IVC) filters with residual acute thrombosis after endovascular therapy.

Methods: A retrospective chart review of 712 patients who underwent retrievable IVC filter implantation between July 2018 and December 2022 was conducted. Residual thrombosis with the IVC filter occurred in 18 patients, and the volume of residual acute thrombosis in the IVC filter exceeded 1 mL in all cases.

Early and midterm outcomes of in situ fenestration via adjustable puncture needle for Ankura aortic stent graft: A single-center experience.

Objectives: An analysis was conducted to demonstrate early and midterm outcomes of using adjustable puncture needle-based in situ fenestration (ISF) technique for Ankura aortic stent graft to reconstruct the supra-arch branch in thoracic endovascular aortic repair (TEVAR).

Methods: A retrospective analysis of 68 cases of aortic lesions with insufficient proximal anchoring area admitted to our department from March 2017 to December 2021 was performed. In situ fenestration thoracic endovascular repair (TEVAR) was performed at the same time during the operation.

LncRNA FGD5-AS1 Promotes Abdominal Aortic Aneurysm Growth Through the Activation of MMP3 in Vascular Smooth Muscle Cells.

Long noncoding RNAs (lncRNAs) can serve as treatment targets for abdominal aortic aneurysms (AAAs). Nonetheless, the exact role of FGD5 antisense RNA 1 (FGD5-AS1) in AAAs is unclear. Therefore, this study investigated the contribution of FGD5-AS1 to AAA growth regulated by vascular smooth muscle cells (VSMCs) and its potential mechanisms.

Efficient electrocatalytic reduction of nitrate to ammonia over fibrous SmCoO under ambient conditions.

We report SmCoO nanofibers as an efficient catalyst for nitrate reduction to ammonia. This catalyst achieves a large NH yield of 14.4 mg h mg.

Vertebral artery course variation leading to an insufficient proximal anchoring area for thoracic endovascular aortic repair.

Backgrounds: We aimed to demonstrate the feasibility of thoracic endovascular aortic repair for type B aortic dissection in patients with an insufficient proximal anchoring area due to the vertebral artery originating from the aortic arch.

Methods: In this study, we report two patients with type B aortic dissection who were complicated with left vertebral artery course variation. Specifically, the left vertebral artery originated from the aortic arch.

Percutaneous mechanical thrombectomy in the management of early acute superior mesenteric artery embolism.

Purpose: This study was performed to summarize our experience in the management of early-stage acute superior mesenteric artery embolism (ASMAE) by percutaneous mechanical thrombectomy (PMT).

Methods: The clinical data of 12 patients with early-stage ASMAE treated by PMT in our institution from November 2019 to September 2021 were retrospectively analyzed. The patients had no obvious evidence of bowel infarction as shown by peritoneal puncture and computed tomography angiography.

Application of Kissing Technique for the Treatment of Superior Vena Cava Syndrome.

Background: Superior vena cava syndrome is a series of symptoms caused by compression of the superior vena cava and its main branches. Endovascular therapy is now widely accepted because it offers rapid, safe and effective relief of clinical symptoms. Few reports have described the application of kissing technique for the treatment of superior vena cava syndrome.

Nuclear Factor Kappa-B/Homeobox A9-Mediated Modulation of Leucine-Rich Repeat Flightless-Interacting Protein 1 Is Involved in Advanced Glycation End Product-Induced Endothelial Dysfunction.

Background: Pathogenesis of cardiovascular diseases begins with endothelial dysfunction. Our previous study has shown that advanced glycation end products (AGE) could inhibit the expression of homeobox A9 (Hoxa9), thereby inducing endothelial dysfunction. Leucine-rich repeat flightless-interacting protein 1 (LRRFIP1) has been found to participate in a variety of pathological processes, but reports of its role in endothelial dysfunction are rare.

Acute Pancreatitis: A Rare Complication After Percutaneous Mechanical Thrombectomy of Portal Vein Thrombosis.

Background: Acute pancreatitis caused by Percutaneous Mechanical Thrombectomy treatment is extremely rare, and so far, no clinical report involving portal veins has been reported. In the article, we summarize this unusual case and share our experience.

Methods: Percutaneous mechanical thrombectomy was performed for the patient who was diagnosed with portal vein thrombosis.

Low heart rate variability relates to the progression of gastric cancer.

Background: Gastric cancer (GC) is one of the most common malignant gastrointestinal tumors with the high morbidity and mortality, affecting the quality of human life. This study aimed to identify the role of heart rate variability (HRV) in patients with GC.

Methods: From January 2010 to June 2014, 383 consecutive patients diagnosed with GC were enrolled in this study.
