Introduction:

Endovascular management of obstructive venous disease (OVD) has rapidly become the first line of therapy and replaced venous bypass.

Aim:

The aim of this study is to compare if there are significant differences between venous stenting in patients with May-Thurner Syndrome (MTS) and intraluminal obstructive lesions.

Material and methods:

We performed a retrospective review to determine the short term of the primary patency of the stents placed in the patients with OVD. Measurements of central tendency and dispersion of variables was performed, bivariate analysis for categorical variable was complete with Chi-square and for groups with <5 cases we utilized Fisher exact test. A value of p < 0.05 was considered significant.

Results:

From 52 patient with OVD, 40 had an intraluminal lesions secondary to thrombosis and 12 with MTS. We observed regression in the Villalta score after stenting in patients who were categorized initially as a severe score. For the short patency term comparing thrombotic vs no thrombotic disease, we obtained a p = 0.046.

Conclusion:

The primary patency of venous stents in the short-term is superior in patients with obstructive non-thrombotic disease (MTS) compared to those from thrombotic etiology, particularly in chronic phases.
