Protocolo diagnóstico y terapéutico de la trombosis venosa

Abstract

Superficial vein thrombosis (SVT) is defined as confirmed thrombosis of the superficial veins. It most commonly affects the lower limbs. The diagnosis is based on clinical suspicion and is confirmed by Doppler ultrasound. Treatment includes general measures and anticoagulation with fondaparinux. Deep vein thrombosis (DVT) is the formation of a thrombus in the deep venous system. It is diagnosed by Doppler ultrasound. Probability scales such as the Wells score have been developed and D-dimer is used to rule out DVT. DVT treatment has two phases—acute and chronic—and is based on anticoagulation. Direct oral anticoagulants (DOACs) or low-molecular-weight heparins (LMWH) are used, followed by an oral anticoagulant. In some cases, surgical interventions such as a thrombectomy may be performed.
