We investigated the clinical presentation and outcomes of patients with DVT based on thrombus sidedness. The authors used the data from the Registro Informatizado Enfermedad TromboEmbólica (RIETE) database (2001-2016) to identify patients with symptomatic proximal lower-extremity DVT. Main outcomes included cumulative 90-day symptomatic pulmonary embolism (PE) and 1-year mortality. Overall, 30,445 patients were included.
