Aujesky D, Thrombosis and embolism are related conditions, but symptoms and treatments may be very different. The d-dimer value is checked one month after anticoagulation ends, with an increased level indicating increased risk.30 However, the ACCP does not recommend its routine use to determine appropriate candidates for indefinite anticoagulation.8, Some conditions, such as pregnancy and cancer, require special consideration when treating VTE. de Gregorio MA, Antithrombotic therapy for VTE disease: CHEST guideline and expert panel report. Oral direct thrombin inhibitors or oral factor Xa inhibitors for the treatment of pulmonary embolism. Decousus H; Superficial vein thrombosis: a current approach to management. Expert consensus guidelines support thrombolytic therapy in patients with persistent hypotension or shock secondary to acute PE.9 Also, when patients with acute PE who are on anticoagulation deteriorate but are not yet hypotensive, systemic thrombolysis is recommended as long as the risk of bleeding is low.8 There is better evidence for systemic thrombolysis than for catheter-directed thrombolysis.8 If systemic thrombolysis fails, catheter-directed thrombolysis is available as a rescue therapy in centers with appropriate expertise. Anticoagulation is the mainstay of VTE treatment. Clinical relevance of symptomatic superficial-vein thrombosis extension: lessons from the CALISTO study. et al. Risk factors for bleeding are summarized in Table 2.9 If there are no contraindications, current guidelines recommend anticoagulation for a minimum of three months for PE and proximal DVT.8,29 If a reversible provoking factor is identified as the cause of VTE, anticoagulation beyond three months is not recommended.7–9 Extended anticoagulation is recommended for patients with an unprovoked VTE and low risk of bleeding.8,9 Indefinite anticoagulation is recommended for patients with a second VTE and low or moderate risk of bleeding.8,9, Comorbidity and reduced functional capacity.
