Thoracic surgery in the elderly--co-morbidity is the limit.

A retrospective chart review was performed in 242 consecutive patients aged 65 years or older who were treated in an academic surgical centre between January 2004 and July 2007. A total of 249 thoracic procedures were performed in 242 patients, of whom 143 were men and 99 women with a mean age of 69.9 years (range 65-92).

Etiology and VTE risk factor distribution in patients with inferior vena cava thrombosis.

Introduction: Inferior vena cava (IVC) thrombosis is a rare event and data detailing the underlying etiology are scarce.

Materials And Methods: Therefore, we reviewed all available cases of IVC thrombosis consecutively registered in the MAISTHRO (MAin-ISar-THROmbosis) database and described the prevalence of VTE risk factors and other conditions contributing to IVC thrombosis development.

Results: 53 patients (35 F, 18 M) with IVC thrombosis aged 12 to 79 years were identified.

High factor VIII levels in venous thromboembolism show linkage to imprinted loci on chromosomes 5 and 11.

High factor VIII (FVIII) levels are known to be a risk factor for deep venous thrombosis, but the mechanisms responsible for high FVIII levels remain unclear. Here, a new phenotype "FVIII level residuum" (FVIII-R) was defined in order to eliminate the impact of common determinants on FVIII levels. We studied 13 families of patients with thrombosis and reproducibly high FVIII levels of unknown origin.
