Management of Superficial Vein Thrombosis in Patients with Varicose Veins: A Survey among Members of National Surgical Society from Republic of Moldova

Purpose

Management of superficial vein thrombosis (SVT) in patients with varicose veins (VV) is not currently standardized. We performed a survey aimed to demonstrate patterns in the management of SVT in the Republic of Moldova.

Materials and Methods

This was a descriptive study whereby members of the National Surgical Society were asked to complete an online questionnaire. In the questionnaire, multiple-choice questions were supplemented with four clinical vignettes of real patients with SVT.

Results

The questionnaire was completed by 102 participants (31.1% response rate). In the treatment of SVT, duplex ultrasound was routinely used by 74.5% of respondents, and anticoagulants were used by 70.5%. The full therapeutic dose of anticoagulants was recommended by 63.3% of surgeons, intermediate dose by 21.1%, and prophylactic dose by 15.6%. Only 50% of respondents were prescribed anticoagulants for 1 month or more. In case of surgical intervention for SVT, crossectomy and stripping were performed by 84.0% of surgeons, while isolated crossectomy by 10.7%. In all clinical vignettes, the majority of respondents opted for urgent surgical treatment. The rate of proponents of surgery varied from 43% in cases of isolated thrombosis of tributaries, and up to 72.5% in cases of thrombosis up to the sapheno-femoral junction.

Conclusion

Management of patients with SVT and VV in the Republic of Moldova is far from standardized. Prescribed doses of anticoagulants, as well as the duration of anticoagulation are highly variable and often contradict the recommendations of current guidelines. Urgent crossectomy and stripping dominate the pattern of current therapeutic approaches.

Long-term risk of venous thromboembolism recurrence after isolated superficial vein thrombosis

Essentials Long-term risk of recurrence of isolated superficial vein thrombosis (SVT) is under-studied. We analyzed data from a cohort of first SVT and proximal deep vein thrombosis (DVT) without cancer. The risk of recurrence as DVT or pulmonary embolism is twice lower in SVT patients. However, overall risk of recurrence is similar between SVT and proximal DVT patients. Click to hear Dr Decousus' perspective on superficial vein thrombosis SUMMARY: Background Isolated superficial vein thrombosis (iSVT) (without concomitant deep vein thrombosis [DVT] or pulmonary embolism [PE]) is a frequent event, but available data on long-term outcomes are scarce and retrospective. Therefore, we aimed to determine prospectively the risk and type of venous thromboembolism (VTE) recurrence after iSVT and compare them with those of proximal DVT. Methods Using data from the prospective, multicenter, observational, OPTIMEV study, we assessed, at 3 years and after anticoagulants were stopped, the incidence and the type of VTE recurrence (iSVT/DVT/PE) of patients with a first objectively confirmed iSVT without cancer (n = 285), and compared these with those of patients with a first proximal DVT without cancer (n = 262). Results As compared with proximal DVT patients, iSVT patients had a similar overall incidence of VTE recurrence (5.4% per patient-year [PY] versus 6.5% per PY, adjusted hazard ratio [aHR] 0.9, 95% confidence interval [CI] 0.5-1.6), but iSVT recurred six times more often as iSVT (2.7% versus 0.6%, aHR 5.9, 95% CI 1.3-27.1) and 2.5 times less often as deep-VTE events (2.5% versus 5.9%, aHR 0.4, 95% CI 0.2-0.9). Varicose vein status did not influence the risk or the type of VTE recurrence. Saphenian junction involvement by iSVT was not associated with a higher risk of recurrence (5.2% per PY versus 5.4% per PY), but was associated with recurrence exclusively as deep-VTE events. Conclusion In patients with a first iSVT without cancer, after stopping anticoagulants, the incidence of deep-VTE recurrence is half that of DVT patients, but the overall risk of recurrence is similar. Ssaphenian junction involvement seems to influence the risk of deep-VTE recurrence, whereas varicose vein status has no impact or a low impact on VTE recurrence.
