A systematic review of the current status of interventions for type II endoleak after EVAR for abdominal aortic aneurysms.

Objective: To study the mid- and long-term outcomes of type II endoleak treatment after EVAR and the technical aspects of different techniques to exclude endoleaks which different embolic agents.

Methods: A systematic review was performed using the approach recommended by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for meta-analyses of interventional studies. The comprehensive search was conducted using the following database: MEDLINE, EMBASE, and the Cochrane Library.

Extracellular traps derived from macrophages, mast cells, eosinophils and neutrophils are generated in a time-dependent manner during atherothrombosis.

Extracellular traps generated by neutrophils contribute to thrombus progression in coronary atherosclerotic plaques. It is not known whether other inflammatory cell types in coronary atherosclerotic plaque or thrombus also release extracellular traps. We investigated their formation by macrophages, mast cells, and eosinophils in human coronary atherosclerosis, and in relation to the age of thrombus of myocardial infarction patients.

Neutrophil Extracellular Traps Participate in All Different Types of Thrombotic and Haemorrhagic Complications of Coronary Atherosclerosis.

Acute coronary syndromes can be initiated by either atherosclerotic fibrous cap ruptures, superficial plaque erosions or intraplaque haemorrhages (IPHs). Since neutrophil extracellular traps (NETs) display pro-inflammatory and pro-thrombotic properties, we investigated the presence, extent and distribution of neutrophils and NETs in different types of plaque complications in relation to the age of overlying thrombus mass or haemorrhage. Sixty-four paraffin-embedded coronary plaque segments of 30 acute myocardial infarction patients were retrieved from the autopsy archives, which contained 44 complicated plaques (17 IPHs, 9 erosions and 18 ruptures) and 20 intact plaques.

Pregnancy-related conditions and premature coronary heart disease in adult offspring.

Objective: To investigate the association between complications during pregnancy and premature coronary heart disease in adult offspring.

Methods: We conducted a population-based case-control study of 153 Indonesian patients with a first acute coronary syndrome (ACS) (age ≤55 years) and 153 age-matched and sex-matched controls. Data on complications during pregnancy (high blood pressure, preterm delivery) and maternal infections in pregnancy were obtained, together with sociodemographic data, clinical profiles, laboratory measurements and adulthood cardiovascular disease (CVD) risk factors at hospital admission or enrolment.

Infections in early life and premature acute coronary syndrome: A case-control study.

Background: Infections in young children may affect the vasculature and initiate early atherosclerosis. Whether infections experienced in childhood play a part in adult clinical cardiovascular disease remains unclear. We investigated the association between infections in early life and the occurrence of premature coronary heart disease.

Laser-assisted vessel welding: state of the art and future outlook.

Laser-assisted vascular welding (LAVW) is an experimental technique being developed as an alternative to suture anastomosis. In comparison to mechanical anastomosis, LAVW is less traumatic, non-immunogenic, provides immediate water tight sealant, and possibly a faster and easier procedure for minimally invasive surgery. This review focuses on technical advances to improve welding strength and to reduce thermal damage in LAVW.

Laser-assisted vascular welding: optimization of acute and post-hydration welding strength.

Background: Liquid solder laser-assisted vascular welding using biocompatible polymeric scaffolds (ssLAVW) is a novel technique for vascular anastomoses. Although ssLAVW has pronounced advantages over conventional suturing, drawbacks include low welding strength and extensive thermal damage.

Aim: To determine optimal ssLAVW parameters for maximum welding strength and minimal thermal damage.

Ex vivo proof-of-concept of end-to-end scaffold-enhanced laser-assisted vascular anastomosis of porcine arteries.

Objective: The low welding strength of laser-assisted vascular anastomosis (LAVA) has hampered the clinical application of LAVA as an alternative to suture anastomosis. To improve welding strength, LAVA in combination with solder and polymeric scaffolds (ssLAVA) has been optimized in vitro. Currently, ssLAVA requires proof-of-concept in a physiologically representative ex vivo model before advancing to in vivo studies.

Biodegradable polymer scaffold, semi-solid solder, and single-spot lasing for increasing solder-tissue bonding in suture-free laser-assisted vascular repair.

We recently showed the fortifying effect of poly-caprolactone (PCL) scaffold in liquid solder-mediated laser-assisted vascular repair (ssLAVR) of porcine carotid arteries, yielding a mean ± SD leaking point pressure of 488 ± 111 mmHg. Despite supraphysiological pressures, the frequency of adhesive failures was indicative of weak bonding at the solder-tissue interface. As a result, this study aimed to improve adhesive bonding by using a semi-solid solder and single-spot vs.

Optimization of suture-free laser-assisted vessel repair by solder-doped electrospun poly(ε-caprolactone) scaffold.

Poor welding strength constitutes an obstacle in the clinical employment of laser-assisted vascular repair (LAVR) and anastomosis. We therefore investigated the feasibility of using electrospun poly(ε-caprolactone) (PCL) scaffold as reinforcement material in LAVR of medium-sized vessels. In vitro solder-doped scaffold LAVR (ssLAVR) was performed on porcine carotid arteries or abdominal aortas using a 670-nm diode laser, a solder composed of 50% bovine serum albumin and 0.

Electrospun poly(ɛ-caprolactone) scaffold for suture-free solder-mediated laser-assisted vessel repair.

Background And Objective: The addition of poly(lactic-co-glycolic) acid (PLGA) scaffolds to liquid solder-mediated laser-assisted vascular repair (sLAVR) has been shown to increase soldering strength significantly. Unfortunately, the fast degradation of PLGA is associated with adverse effects such as acidity of the degradation products. This study investigated the possibility of using electrospun poly(ɛ-caprolactone) (PCL) as reinforcement material in scaffold and solder-mediated LAVR (ssLAVR).
