Impact of venography on the diagnosis and management of deep vein thrombosis.

Value of assessment of pretest probability of deep-vein thrombosis in clinical management.

BACKGROUND When ultrasonography is used to investigate deep-vein thrombosis, serial testing is recommended for those who test negative initially. Serial testing is inconvenient for patients and costly. We aimed to assess whether the calculation of pretest probability of deep-vein thrombosis, with a simple clinical model, could be used to improve the management of patients who present with suspe...

The Prevalence and Risk Factors of Venous Thrombosis among Hospitalized Patients: Are Wells Criteria Considered by Primary Care Physicians?

Background: Deep vein thrombosis (DVT) is one of the main causes of hospital mortality which can easily be prevented. Three para clinical methods are used to confirm the diagnosis of DVT, which include D-dimer test, venous color Doppler ultrasonography and venography. This study has focused on the prevalence of confirmed DVT in lower limbs based on venous color Doppler ultrason...

The role of emergency venography in the diagnosis and management of deep venous thrombosis.

A retrospective study of patients who had undergone venography for suspected deep venous thrombosis during a six month period was undertaken to assess the influence of the examination on the subsequent management. Of these patients 38.6% had evidence of thrombus confirmed by the examination. This figure is comparable with other published results and did not bear out the impression that too many...

May-Thurner syndrome, an uncommon diagnosis for a common disease: a case report and review of the literature

May-Turner syndrome is a relatively uncommon anatomical variation in which patients develop iliofemoral deep vein thrombosis (DVT) due to venous occlusion. In this syndrome, the left common iliac vein is compressed against the fifth lumbar vertebra by the right common iliac artery. The real incidence/prevalence of May-Turner syndrome is not precisely known, but it is estimated to be between 22 ...
