”My Top 6 Teaching Points from the JAMA 2025 Review on Superficial Vein Thrombosis by Gregory Piazza and colleagues.
Excellent Review Paper, Congratulations to the Authors
1. Clinical Relevance and Risk of VTE
SVT has a meaningful risk of progression to deep vein thrombosis (DVT) or pulmonary embolism (PE), especially if untreated, up to 10% of patients develop DVT or PE. Approximately 25% present with concomitant DVT, and thromboembolic events can occur in up to 7% within 90 days of SVT diagnosis
2. Diagnosis: Clinical and Imaging Approach
SVT typically presents with a tender, palpable cord and erythema along a superficial vein. While history and physical are often sufficient, duplex US should be performed if there is diagnostic uncertainty, concern for extension, or major risk factors. D-dimer is not sensitive enough to reliably exclude SVT
3. Risk Stratification
Key risk factors for SVT include varicose veins, pregnancy, cancer, indwelling catheters (for upper extremity SVT), immobilization, obesity, and history of VTE. Prognosis is worse for patients with cancer, male sex, absence of varicose veins, or involvement of the saphenofemoral/popliteal junction
4. Indications for Anticoagulation
Anticoagulation is strongly recommended for:
• SVT ≥ 5 cm in length,
• SVT with symptoms refractory to conservative therapy,
• SVT within 3 cm of a deep vein (should be treated as DVT with therapeutic anticoagulation).
First-line therapy is fondaparinux 2.5 mg daily for 45 days; alternatives include rivaroxaban 10 mg daily or enoxaparin 40 mg daily
5. Conservative Measures and Other Therapies
Elastic compression stockings and NSAIDs offer symptomatic relief and are appropriate in select low-risk cases. Topical therapies (such as heparin ointment) may add symptom benefits, but surgical/ablative intervention is not routinely advised unless significant venous reflux is confirmed
6. Follow-Up and Outcomes
Patients should be counseled to seek further evaluation if symptoms worsen or fail to improve within 7 days. Early follow-up duplex US is advised for proximal progression or new symptoms. Residual reflux is common after SVT and may lead to chronic venous insufficiency, but evidence for reducing post-SVT ulceration is still lacking.
