To predict neonatal survival and pulmonary hypertension by measurement of fetal pulmonary artery reactivity to maternal hyperoxygenation in fetuses with severe congenital diaphragmatic hernia treated by fetoscopic endoluminal tracheal occlusion (FETO). Thirty-eight fetuses underwent FETO at around 28 weeks' gestation and the balloon was removed at 34 weeks in most ...

The hepatopulmonary syndrome (HPS) is a severe vascular complication in lungs resulting in systemic hypoxemia in patients with cirrhosis and portal hypertension. The underlying structural change in HPS is intrapulmonary vasodilation, which can lead to impaired oxygenation of pulmonary venous blood. It has been demonstrated that the heme oxygenase-1/carbon monoxide ...

Pulmonary arterial hypertension is characterized by elevated pulmonary artery pressure and vascular resistance. In women the incidence is 4-fold greater than that in men. Studies suggest that sustained vasoconstriction is a factor in increased vascular resistance. Possible vasoconstrictor mediators include arachidonic acid-derived lipoxygenase (LO) metabolites. Our studies in rabbits showed ...

The perfusion territory of the pedicled internal mammary artery perforator flap has been described, but the number of perforators to be included in the flap's pedicle is controversial. We studied the vascular territory of the dominant perforator and the contribution of additional nondominant perforators to it. Therefore, the dominant perforators ...

Left pulmonary artery (LPA) sling is a very rare anomaly in which the LPA arises distally, far from the right pulmonary artery on the right side of the distal trachea, turns sharply leftwards around the trachea and courses to the left lung hilum through the space between the trachea and ...

A retrospective cohort study of 2,218 patients with deep vein thrombosis or pulmonary embolism during a 25-year period from 1966-1990 in Minnesota showed an annual incidence of venous thromboembolism of 117 per 100,000 (deep vein thrombosis, 48 per 100,000; pulmonary embolism, 69 per 100,000). Higher rates were found in males ...

A seventeen-month-old male baby, who had received conventional biventricular repair for congenitally corrected transposition of the great arteries, underwent excision of supratricuspid ring. Although tricuspid valve annulus was marginally small on direct inspection in the operating theater, circumferential excision of supratricuspid ring alone completely relieved the right ventricular inflow obstruction.

The valve sinuses of the deep venous system are frequent sites of venous thrombus initiation. We previously reported that, in comparison with the non-valvular lumenal endothelium, the valve sinus endothelium had decreased expression of von Willebrand factor (vWF) and increased expression of endothelial protein C receptor (EPCR) and thrombomodulin (TM), ...

Healthy human lungs are normally the sites of fluid and solute filtration across the pulmonary capillary endothelium. Unlike other organs, the filtrate in the lungs is confined anatomically within adjacent interstitial spaces, through which it moves by a built-in pressure gradient from its site of formation to its site of ...

OBJECTIVES: Dilatation of the pulmonary autograft has been observed after the Ross procedure. Whether the remaining native aorta dilates is not known. The aim of the study was to describe the prevalence and severity of autograft and native aortic dilatation over time and to identify possible determinants. METHODS: Ninety-one adult ...

Coronary atherosclerosis still represents the major cause of mortality in western societies. Initiation of atherosclerosis occurs within the intima, where major histological and molecular changes are produced during pathogenesis. So far, proteomic analysis of the atherome plaque has been mainly tackled by the analysis of the entire tissue, which may ...

Patients with thoracic aortic aneurysms sometimes also have peripheral vascular disease. In such cases, staged operations are usually performed in order to avoid additional morbidity. We have achieved good long-term outcomes in 2 patients with use of a single-stage surgical technique. Our novel procedure uses a pre-sewn side branch with ...

Spontaneous left internal mammary artery (LIMA) dissection is an extremely rare condition. It generally occurs as a complication of interventional manipulation in the early post-operative period. Here we present a case of spontaneous LIMA dissection nine years after surgery seemed to be chronic deforming jetflow secondary to kinking segment of ...

The prevalence of coronary anomalies in the transposition of the great arteries is high. Transfer of the coronary arteries during arterial switch operation is the principle step and incomplete transport of the coronary arteries to the neoaortic root results into iatrogenic coronary problems. We present a case with the residual ...

Five hundred consecutive cases with histologic chorioamnionitis and umbilical cord inflammation were analyzed to develop a staging system for funisitis and to correlate stage of funisitis with stage of chorioamnionitis in order to estimate the timing of various stages of funisitis. Funisitis progresses through venous involvement (with or without Wharton's ...

The relationship between chronic obstructive pulmonary disease (COPD) and atherosclerosis has been suggested; this association may relate to systemic inflammation and endothelial dysfunction, which can lead to alteration of small pulmonary vessels. The relationship between atherosclerosis and small pulmonary vessel alteration, however, has not been assessed in COPD patients. We ...

We describe the benefits of simulating lung segmentectomy by using multi-detector computed tomographic angiography. Preoperative determination of the anatomical, intersegmental plane is possible by visualizing the branches of the pulmonary veins. This new technique could be useful in thoracoscopic segmentectomy of the lung.

Idiopathic pulmonary fibrosis (IPF) is often associated with elevations in pulmonary artery pressures. Although primary pulmonary arterial hypertension (PAH) has been associated with primary graft dysfunction (PGD), the role of secondary PAH in mediating PGD risk in patients with IPF is incompletely understood. The purpose of this study was to ...

Amiodarone, a bi-iodinated benzofuran derivative, is, because of its high effectiveness, one of the most widely used antiarrhythmic agents. However, adverse effects, especially potentially fatal and non-reversible acute and chronic pulmonary toxicity, continue to be observed. This review provides an update of the epidemiology, pathophysiology, clinical presentation, treatment and outcome ...

Cytauxzoonosis, caused by Cytauxzoon felis, is a regionally common, often fatal tick-borne disease primarily affecting the domestic cat. Retrospective analysis of case records from January 1995 to June 2005 identified 148 domestic cats diagnosed with cytauxzoonosis, having suitable archived lung sections. Lung sections were examined and graded on relevant parameters, ...

Lung transplantation (LT) represents the only available therapy for selected patients affected by end-stage pulmonary disease. Cardiopulmonary bypass (CPBP) is used, when required, during single and sequential double lung transplantation; however, it increases the risk of bleeding, early graft dysfunction, failure, and other potential side effects. We report our experience ...
