The diagnosis of symptomatic recurrent pulmonary embolism and deep vein thrombosis: guidance from the SSC of the ISTH

This document is intended to give clinical guidance for the diagnosis of symptomatic recurrent pulmonary embolism (PE) and/or deep vein thrombosis (DVT). We define recurrent PE and DVT as those events occurring after an initial course of adequate antithrombotic treatment for a first venous thromboembolic event (VTE) [1,2]. The issue of a correct diagnosis of recurrence is clinically relevant since many patients with a previous VTE will complain of signs or symptoms suggesting the possibility of a recurrent event.
