STUDY QUESTION Is venous thrombosis risk increased in pregnancies after in vitro fertilization? SUMMARY ANSWER The venous thrombosis incidence was significantly increased in pregnancies after in vitro fertilization; especially in the first trimester and in the first 6 weeks post-partum. WHAT IS KNOWN ALREADY In vitro fertilization without pregnancy is not associated with increased venous th...

Venous thrombosis typically involves the lower extremity circulation. Rarely, it can occur in the cerebral or splanchnic veins and these are the most frightening manifestations because of their high mortality rate. A third site of rare venous thrombosis is the deep system of the upper extremities that, as for the lower extremity, can be complicated by pulmonary embolism and post-thrombotic synd...

T here are no evidence based studies dealing with the incidence of venous sheath related thrombosis and the role of heparin, particularly in the setting of prolonged procedures with multiple lines. The clinical importance of catheter related thrombosis remains undefined in the setting of electrophysiological studies (EPS). We sought to determine the incidence of multiple venous sheath related t...

Venous thrombosis which mainly manifests as deep vein thrombosis of the leg or pulmonary embolism occurs in 1 per 1000 per year. It occurs due to interacting genetic, environmental and behavioral risk factors. The strongest risk factors are certain types of surgery and malignancies. Over the last decade many new risk factors for venous thrombosis have been identified. Venous thrombosis has a hi...

BACKGROUND The risk of recurrent venous thrombosis is 2-fold higher in men than in women. In contrast, no such sex difference in the risk of first venous thrombosis has been reported. We hypothesized that, for a first event, a risk difference between the sexes is masked by female exposure to reproductive factors (oral contraception, pregnancy/puerperium, and postmenopausal hormone therapy). M...

This is a case study of a 34-year-old woman who was admitted to hospital with a history of severe orthostatic headache. She was diagnosed as having spontaneous intracranial hypotension (SIH) by undetectable cerebrospinal fluid (CSF) pressure at lumbar puncture, and with evidence of diffuse dural enhancement of the brain detected by magnetic resonance imaging (MRI). However, the contrast-enhance...

UNLABELLED Some patients with acute deep venous thrombosis of the lower limbs may present risk factors for recurrent disease. AIMS To analyze the most important conditions related to recurrent deep venous thrombosis of the lower limbs, other than thrombophilias. PATIENTS AND METHODS We examined 88 consecutive patients (47 males-53.41%, average age 64.9 +/-13.9 years) admitted to a Medical C...

AIM This paper reports a systematic review whose objective was to evaluate the effectiveness of graduated compression stockings as prophylaxis for flight-related venous thrombosis, including deep vein thrombosis and superficial venous thrombosis, after air travel in the general population. BACKGROUND Despite the extended history of the use of graduated compression stockings, their application...

Plasma D-dimer concentration rises more than 100-fold during acute deep vein thrombosis, but there are no prospective data concerning D-dimer as a risk factor for incident venous thrombosis in a general population. Incident venous thrombosis was ascertained in 2 prospective observational studies, the Atherosclerosis Risk in Communities Study and the Cardiovascular Health Study. Of 21 690 partic...
