We describe the case of a 68-year-old man who presented with a massive lesion in the right liver. It was confirmed by preoperative aspiration biopsy to be a case of moderately differentiated hepatocellular carcinoma, and the patient was shown by immunohistochemistry to have a mutation in the p53 gene. The ...

Rodent models are increasingly used to study the development and progression of arterial stiffness. Both the non-invasive Doppler derived Pulse Wave Velocity (PWV) and the invasively determined arterial elastance index (EaI) have been used to assess arterial stiffness in rats and mice, but the need for anesthetic agents to make ...

Plaque formation is confined to the arterial trunk. We assumed that due to the higher aeration of arterial compared to venous blood, higher levels of the atherogenic agent oxidized LDL might be present in arteries, contributing to plaque formation. We aimed to compare (i) the basal oxidative status of LDL ...

The timing of aortic valve intervention (AVI) in pediatric patients with chronic aortic insufficiency (AI) is largely based on adult experience, which is fraught with uncertainty and controversy. Current adult guidelines in the absence of symptoms use left ventricular (LV) systolic function and LV dimensions to guide AVI timing, with ...

Cephalothoracopagus embryos are conjoined twins, who share parts of their heads, necks and bodies. Our study aims at presenting a detailed morphological analysis of a cephalothoracopagus chick embryo of developmental stage 31. Because none of the existing theories can explain the genesis of the phenotype of this embryo, we also ...

BackgroundMany cerebral aneurysms can be treated effectively with intracranial stents. Unfortunately, stents can occlude perforating vessels near the treatment site which can decrease cerebral perfusion and increase the risk of stroke.MethodsParticle image velocimetry was used to investigate the effects of intracranial stents on flows in perforators near a treated aneurysm. ...

Severe vascular access complications are infrequent, yet potentially life-threatening, conditions related to percutaneous procedures approached via the femoral artery. Surgical vascular repair of such complications are associated with high rates of morbimortality due to advanced cardiovascular disease. Endovascular repair of the injured vessel appears to be the treatment of choice ...

The demographics of ageing are changing dramatically such that there will be many more older adults in the near future. This setting is projected to produce a new 'boomer-driven' epidemic of physiological dysfunction, disability and risk of chronic degenerative disorders, including cardiovascular diseases. Standing out against this dreary biomedical forecast ...

PURPOSE OF REVIEW: To review the most used tests for diagnosis of pulmonary hypoplasia, and their pertinence in different pathological conditions. RECENT FINDINGS: The two-dimensional biometric parameters are not accurate enough to be applied in clinical practice, except for the lung-to-head ratio (LHR): the observed/expected LHR remains the best predictor ...

Sinus of Valsalva aneurysms (SVAs) are uncommon but important entities. They are most often congenital in origin, resulting from incomplete fusion of the aortic media to the aortic valve annulus. Less frequently, they may be acquired, usually secondary to infective endocarditis. Unruptured aneurysms may be clinically silent and diagnosed incidentally, ...

Pulmonary intravascular macrophages (PIMs) are constitutively found in species such as cattle, horse, pig, sheep, goat, cats, and whales and can be induced in species such as rats, which normally lack them. It is believed that human lung lacks PIMs, but there are previous suggestions of their induction in patients ...

The pulmonary artery (PA) wall, which has much higher hydraulic conductivity and albumin void space and approximately one-sixth the normal transmural pressure of systemic arteries (e.g, aorta, carotid arteries), is rarely atherosclerotic, except under pulmonary hypertension. This study constructs a detailed, two-dimensional, wall-structure-based filtration and macromolecular transport model for the ...

The proximity of the coronary arteries and the bundle of His to the aortic valve may contribute to the pathogenesis of arrhythmias in patients with aortic valve disease. Severe aortic valve disease may also adversely alter left ventricular hemodynamics (end-diastolic dimensions and wall stress) and thus create a substrate for ...

Carotid artery stenting (CAS) has emerged as a minimally invasive alternative to endarterectomy but its use in clinical treatment is limited due to the post-stenting complications. Haemodynamic actors, related to blood flow in the stented vessel, have been suggested to play a role in the endothelium response to stenting, including ...

The effects of fluid-structure interactions (FSI) and pulsation on the transport of low-density lipoprotein (LDL) through an arterial wall are analyzed in this work. To this end, a comprehensive multi-layer model for both LDL transport as well as fluid-structure interaction (FSI) is introduced. The constructed model is analyzed and compared ...

Although most ischemic strokes are thromboembolic in origin and their management is endovascular or medical, some are hemodynamic in origin and their management may be surgical. Extracranial-intracranial bypass with superficial temporal artery-to-middle cerebral artery (MCA) bypass, high-flow interposition grafts, and reconstructive techniques have been developed. Clinical indications and efficacy are ...

For patients who need long-term central venous access but who have developed obstruction of the usual central veins, "salvage" access techniques offer successful alternatives. These techniques include translumbar inferior vena cava access, transhepatic inferior vena cava access, catheterization of small venous collaterals, and recanalization of occluded veins. Inferior vena cava ...

A 55-year-old man with massive pulmonary thromboembolism underwent thrombolysis, pulmonary artery embolectomy and tricuspid annuloplasty. Nine months later, a mobile echogenic intra-cardiac mass was found in the tricuspid valve. Because the patient had undergone annuloplasty, thrombosis was suspected as the most likely diagnosis and thrombolytic therapy was instituted. However, the ...

Ventricular septal defect (VSD) can be associated with various complications such as aortic regurgitation (AR). AR in VSD come from a deficiency or hypoplasia of the conal septum which leads to abnormal apposition in diastole and prolapse of the poorly supported noncoronary or right coronary cusp through the VSD into ...

BACKGROUND: Less invasive methods of determining cardiac output are now readily available. Using indicator dilution technique, for example has made it easier to continuously measure cardiac output because it uses the existing intra-arterial line. Therefore gone is the need for a pulmonary artery floatation catheter and with it the ability ...

Dual-lumen haemodiafiltration catheters enable continuous renal replacement therapy in the critically ill and are often co-located with central venous catheters used to infuse drugs. The extent to which infusions are immediately aspirated by an adjacent haemodiafiltration catheter remains unknown. A bench model was constructed to evaluate this effect. A central ...

Carotid aneurysm is a rare condition and mostly caused by atherosclerosis, trauma, or fibrodysplasia. Angiosarcoma is an unusual cause for large vessels' aneurysms and a rare malignant neoplasm that may occur in any region of the body, yet seldom originates in the large blood vessels. We report a rare case ...

Pulmonary arterial stenoses commonly occur in patients with congenital heart disease. Indications for treatment are based around reduction of right ventricular hypertension and equalization of flow to each lung and its constituent segments. There are many treatment approaches for these lesions depending on the anatomy, location and the age of ...

Venous thrombosis and arterial thrombosis are traditionally regarded as two different diseases with respect to pathophysiology, epidemiology, and treatment strategies. Research findings of the past few years suggest that this categorical distinction may be too strict. However, whether the described relationship between venous and arterial thrombosis is real or a ...
