True lumen expansion but no aortic remodeling following thoracic endografting and distal bare stent for subacute complicated type B aortic dissection.

Background: The effects of thoracic endovascular aneurysm repair (TEVAR) with additional distal bare metal stents (BMSs) in patients with subacute complicated type B aortic dissection (cTBAD) are unclear and are investigated in this retrospective study.

Methods: The medical records of 67 patients who received TEVAR due to subacute cTBAD were reviewed. Areas of true lumen (TL) and false lumen at five levels-pulmonary artery (PA), diaphragm, renal artery (RA), middle of the infrarenal aorta, and aortic bifurcation-were measured using computed tomography before and 3, 6, and 12 months after surgery.

Nattokinase attenuates endothelial inflammation through the activation of SRF and THBS1.

Natto contains a potent fibrinolytic enzyme called nattokinase (NK), which has thrombolytic, antihypertensive, antiatherosclerotic and lipid-lowering effects. Although NK has been recognized for its beneficial effect on humans with atherosclerotic cardiovascular disease (ASCVD), the underlying mechanisms involved in vascular inflammation-atherosclerosis development remain largely unknown. The current study aimed to explore the effects of NK on gene regulation, autophagy, necroptosis and inflammasome in vascular inflammation.

Layer-by-layer assembly of quercetin-loaded zein/γPGA/low-molecular-weight chitosan/fucoidan nanosystem for targeting inflamed blood vessels.

Chitosan acts as a versatile carrier in polymeric nanoparticle (NP) for diverse drug administration routes. Delivery of antioxidants, such as quercetin (Qu) showcases potent antioxidant and anti-inflammatory properties for reduction of various cardiovascular diseases, but low water solubility limits uptake. To address this, we developed a novel layer-by-layer zein/gamma-polyglutamic acid (γPGA)/low-molecular-weight chitosan (LC)/fucoidan NP for encapsulating Qu and targeting inflamed vessel endothelial cells.

Tolvaptan has been approved for the treatment of autosomal dominant polycystic kidney disease and heart failure. However, the role of tolvaptan in patients with abdominal aortic aneurysm (AAA) has not been examined. Human aortic smooth muscle cells (HASMCs) were used as the in vitro model.

Identification of a Novel Theranostic Signature of Metabolic and Immune-Inflammatory Dysregulation in Myocardial Infarction, and the Potential Therapeutic Properties of Ovatodiolide, a Diterpenoid Derivative.

Myocardial infarction (MI) is a multifactorial global disease, recognized as one of the leading causes of cardiovascular morbidity and mortality. Timely and correct diagnoses and effective treatments could significantly reduce incidence of complications and improve patient prognoses. In this study, seven unconventional differentially expressed genes (DEGs) (MAN2A2, TNFRSF12A, SPP1, CSNK1D, PLAUR, PFKFB3, and CXCL16, collectively termed the MTSCPPC signature) were identified through integrating DEGs from six MI microarray datasets.

Aortic remodeling of the provisional extension to induce complete attachment technique in DeBakey type IIIb aortic dissection.

Background/purpose: Data about volumetric remodeling of the provisional extension to induce complete attachment (PETTICOAT) technique on DeBakey type IIIb aortic dissection in acute and subacute phases were scarce. The proper timing to perform this technique to promote false lumen reduction was also unknown.

Methods: Patients with DeBakey type IIIb aortic dissection who underwent the PETTICOAT technique between December 2005 and March 2017 were reviewed and divided into acute (treatment occurred ≦14 days after symptom onset) and subacute (15-90 days) groups.

Thrombus-specific theranostic nanocomposite for codelivery of thrombolytic drug, algae-derived anticoagulant and NIR fluorescent contrast agent.

Thrombolysis is a standard treatment for rapidly restoring blood flow. However, the application of urokinase-type plasminogen activator (Uk) in clinical therapy is limited due to its nonspecific distribution and inadequate therapeutic accumulation. Precise thrombus imaging and site-specific drug delivery can enhance the diagnostic and therapeutic efficacy for thrombosis.

Endovascular aortic repair is a cost-effective option for in-hospital patients with abdominal aortic aneurysm.

Background: To investigate the cost-effectiveness of endovascular aortic repair (EVAR) versus open aortic repair (OAR) for abdominal aortic aneurysm (AAA) using incremental costs per decreased in-hospital mortality rate gained through our patients' cohort.

Methods: Medical records and healthcare costs of patients with AAA hospitalized between 2010 and 2015 were extracted from the National Health Insurance Research Database (NHIRD) of Taiwan. Multiple regression analysis was applied to adjust for confounding factors and to compare the differences in postoperative clinical outcomes between patients who received EVAR and OAR.

Hydrogen Sulfide Attenuates Aortic Remodeling in Aortic Dissection Associating with Moderated Inflammation and Oxidative Stress through a NO-Dependent Pathway.

Aortic dissection (AD) is a highly lethal vascular disease characterized by separation of the constituent layers of the aortic wall. An increasing body of research indicates that inflammatory response and oxidative stress are implicated in vascular remodeling, which plays a key role in the development of AD. Hydrogen sulfide (HS) has been found to protect against various types of cardiovascular disease, including myocardial infarction, arthrosclerosis, and hypertension.

Flow density of computed tomography aortography for predicting early unfavorable aortic remodeling after TEVAR in type IIIb aortic dissection.

Objective: Patients diagnosed of DeBakey type III aortic dissection with partial thrombosis of false lumen (FL) have a higher mortality rate. However, IIIb dissections with full patent FL tend to exhibit a partially thrombosed FL quickly after thoracic endovascular aortic repair (TEVAR); thus, we investigated survival and aortic remodeling in this population.

Methods: We reviewed computed tomography aortograms (CTAs) of 123 patients with TEVAR-treated IIIb aortic dissections from July 2006 to June 2015; contrast density of CTAs represented intraluminal flow.

Midterm result of custom-made iliac branch device for common iliac aneurysm with and without abdominal aortic aneurysm.

Objectives: Although commercial iliac branch devices offer a new and valid endovascular approach to treating iliac aneurysm and effectively preserve antegrade flow of the internal iliac artery, their use may not be suited for all types of challenging anatomy, especially isolated common iliac artery aneurysm. Our custom-made iliac bifurcation device has a unique design and excludes both combined and isolated iliac branch aneurysm. This study validated the efficacy and safety of the custom device by comparing clinical outcomes between groups receiving commercial and custom devices.

Objectives: To compare the outcomes of using iliac branch devices (IBD) and the crossover chimney (COCh) technique for preserving the internal iliac artery (IIA) during endovascular aortic repair in patients with common iliac aneurysm (CIA).

Methods: From February 2010 to July 2016, we recruited 61 consecutive and elective patients. Thirty of them received the IBD, and the remaining 31 received the COCh.

Health-related quality of life in patients with abdominal aortic aneurysm undergoing endovascular aneurysm repair: A cross-sectional study.

Background: Endovascular aneurysm repair (EVAR) has become a common surgical treatment for abdominal aortic aneurysm (AAA), and postoperative health-related quality of life (HRQoL) is drawing increasing attention. Most studies compare HRQoL in EVAR patients and open aneurysm repair patients, while few studies have investigated HRQoL in EVAR patients versus the general population. This study aimed to investigate whether HRQoL differs between patients with EVAR patients and the general population.

CT Angiography Findings Predictive of Kidney Injury in Chronic Aortic Dissection.

The purpose of this study was to compare the volume alteration and effective renal plasma flow of kidneys supplied by false lumens (FLs) with those of kidneys supplied by true lumens (TLs), to show the discrepancy in perfusion between the two lumens. We sought to corroborate malperfusion of FL-supplied kidneys with imaging characteristics observed on CT angiography. A retrospective analysis was conducted using prospectively collected data for 87 patients with a diagnosis of residual chronic aortic dissection between 2005 and 2013 who had one kidney perfused by a TL and the other kidney perfused by a FL.
