Pulmonary embolism is a serious, life-threatening condition and most commonly derives from deep vein thrombosis of the lower extremities. Once deep vein thrombosis (DVT) reaches a proximal vein (i.e., popliteal vein or higher), pulmonary embolism reportedly occurs in up to 50% of patients. Case Presentation. We report on an inpatient with major depressive disorder in a catatonic state in whom a...

Background Ovarian vein thrombosis is a rare complication of pregnancy. The representative complaints of patients with ovarian vein thrombosis are abdominal pain and fever. In some cases, however, fatal pulmonary embolism may develop. We report a case of pulmonary embolism presenting with severe hypotension and loss of consciousness during cesarean section possibly caused by ovarian vein thromb...

OBJECTIVE Lobectomy with pulmonary artery resection and reconstruction is seldom performed in order to avoid pneumonectomy in selected cases. The aim of this study is to determine how safe and effective the graft reconstruction of the pulmonary artery is, using autologous tissue taken from the pulmonary vein. METHODS Eight patients with diagnosed non-small-cell lung cancer were treated by lob...

Exercise-induced pulmonary hemorrhage is a performance-limiting condition of racehorses associated with severe pathology, including small pulmonary vein remodeling. Pathology is limited to caudodorsal (CD) lung. Mechanical properties of equine pulmonary microvasculature have not been studied. We hypothesized that regional differences in pulmonary artery and vein mechanical characteristics do no...

Recent clinical studies have shed new light on the diagnosis of venous thromboembolism. Pulmonary embolism continues to be difficult to diagnose because the definitive test, pulmonary angiography, is complex and not widely available. However, new knowledge about ventilation perfusion lung scanning and non-invasive leg studies can help to reduce the need for pulmonary angiography. Furthermore, t...

It is well known that deep vein thrombosis of the upper extremities is linked to high morbidity/mortality, resulting in 12-20% of all documented pulmonary embolism; however, there are few data about thromboembolism originating from a vein and/or a branch of a superficial vein of the upper extremities. Pulmonary embolism secondary to upper limb superficial vein thrombosis (not combined with uppe...

Thrombus formation in a pulmonary vein stump after pulmonary lobectomy is extremely rare, but can trigger cerebral embolism of unknown cause. We encountered a case of cerebral embolism in a 58-year-old man 2 days after left upper lobectomy. Since intravenous administration of recombinant tissue plasminogen activator was contraindicated, thrombus removal by endovascular reperfusion therapy was p...

Background. We studied the role of pulmonary veins in cancer progression using computed tomography (CT) scans. Methods. We obtained data from 260 patients with pulmonary vein obstruction syndrome (PVOS). We used CT scans to investigate pulmonary lesions in relation to pulmonary veins. We divided the lesions into central and peripheral lesions by their anatomical location: in the lung parenchyma...

OBJECTIVES Total anomalous pulmonary venous connection (TAPVC) is a rare congenital heart disease. This study aimed to evaluate the outcomes of TAPVC repair in neonates, controlling for anatomic subtypes and surgical techniques. METHODS Between 1997 and 2013, 88 patients (median age: 16 days) underwent repair for supracardiac (31), cardiac (18), infracardiac (36), or mixed (3) TAPVC. All the ...

Increased vascular permeability characterizes lung injury pulmonary edema and renders fluid balance in the injured lung especially sensitive to changes in hydrostatic pressure. Pulmonary edema is often associated with increased sympathetic nervous system activity which can lead to pulmonary venoconstriction. This postcapillary venoconstriction could raise microvascular pressure and might theref...
