The Wells rule and D-dimer for the diagnosis of isolated distal deep vein thrombosis.
Pretest clinical probability with the Wells rule and D-dimer have been widely investigated for the diagnosis of symptomatic proximal deep vein thrombosis (DVT) of the lower limbs, but they have not been formally tested for symptomatic isolated distal DVT diagnosis. ⋯ In clinically suspected DVT with negative proximal compression ultrasonography, pretest clinical probability with the Wells rule has a low diagnostic accuracy for isolated distal DVT. D-dimer has a better negative predictive value, but alone it does not exclude isolated distal DVT. In patients with low pretest clinical probability, D-dimer had a negative predictive value of > 95% for isolated distal DVT.

Multicenter Study Clinical TrialSafety and efficacy of low-dose fondaparinux (1.5 mg) for the prevention of venous thromboembolism in acutely ill medical patients with renal impairment: the FONDAIR study.
Renal impairment is common, affecting around 40% of acutely ill medical patients, and is associated with an increased risk of both venous thromboembolism (VTE) and bleeding. The clinical benefit of effective thromboprophylactic strategies may be outweighed in these patients by an excessive rate of hemorrhage. ⋯ The addition of moderate to severe renal impairment to patients with traditional risk factors for VTE identified a population of very elderly acutely ill medical patients potentially at high risk of both VTE and bleeding complications. The recently approved lower prophylactic dose of fondaparinux appears to be a safe and relatively effective strategy in these patients.

Multicenter Study Comparative StudyProspective comparison of clinical prognostic scores in elder patients with a pulmonary embolism.
The Geneva Prognostic Score (GPS), the Pulmonary Embolism Severity Index (PESI) and its simplified version (sPESI) are well-known clinical prognostic scores for a pulmonary embolism (PE). ⋯ In this cohort of elderly patients with PE, the GPS identified a higher proportion of patients as low risk but the PESI and sPESI were more accurate in predicting mortality.
