Objective: The aim was to validate the SYM VEIN consensus 3D scoring tool in chronic venous disease (CVD).
Methods: This was a prospective cohort study with a total of 35 consecutive patients with CVD. Patients with CVD undergoing saphenectomy were assessed with the revised Venous Clinical Severity Score (r-VCSS), the CIVIQ-20 quality of life score questionnaire, and the SYM VEIN consensus statement 3D system, pre-operatively and four weeks post-operatively. The total 3D score was tested for reliability, construct validity, and responsiveness.
Results: The total 3D score demonstrated good reliability and internal consistency (Cronbach's alpha 0.85). Principal component analysis identified three groups of symptoms (paraesthesia, burning pain, and pruritus, vs. heaviness, sensation of swelling and aching/pain, vs. restless leg and throbbing pain) demonstrating a high intragroup correlation and likely to share similar pathophysiology, indicative of adequate construct validity. The total 3D score showed a significant correlation with r-VCSS and CIVIQ-20 score (rho .46, p = .005 and rho .65, p < .001, respectively) indicative of adequate convergent validity. After saphenectomy, significant reductions (p < .001) of the total 3D, and 3D scores for all but two individual venous symptoms were observed, indicative of excellent responsiveness. Median total 3D score was reduced from 31 to 6 (83.8% decrease, p < .001), median r-VCSS was reduced from 6 to 0 (100% decrease, p < .001), and median CIVIQ-20 score was reduced from 24 to 14 (40% decrease, p < .001). The difference of median percentage change between r-VCSS and CIVIQ-20 score vs. total 3D score was significant (p = .005 and p < .001, respectively).
Conclusion: The total SYM VEIN 3D score has good reliability, construct validity and excellent responsiveness, although less prone to change after saphenectomy compared with r-VCSS.

Objective: Venous thoracic outlet syndrome (VTOS), a compression syndrome of the subclavian vein at the costoclavicular junction, is commonly treated with first rib resection. This invasive procedure carries a risk of serious complications. The purpose of this single-center cross-sectional study was to evaluate the long-term outcome of non-bony decompression by resection of the subclavius muscle and tendon and to provide a detailed description of the procedure.

Objective: There are varying anatomical and mechanical demands of stent placement in the iliofemoral venous segment; the Duo Venous Stent System is designed to address these issues. The purpose of the VIVID (Venous stent for the Iliofemoral Vein Investigational clinical trial using the Duo Venous Stent System) study was to investigate the safety and efficacy of the Duo Venous Stent System for the treatment of patients with nonmalignant iliofemoral venous obstructive disease.
Methods: This was an international, prospective, multicenter, single-arm study that enrolled patients with symptomatic nonthrombotic (NT), post-thrombotic (PTS), or acute deep vein thrombotic (aDVT) iliofemoral venous outflow obstruction.

In previous animal model studies, we demonstrated the potential of rAAV2-sVEGFRv-1, which encodes a truncated variant of the alternatively spliced soluble version of VEGF receptor-1 (VEGFR1), as a human gene therapy for age-related macular degeneration (AMD) and diabetic retinopathy (DR). Here, we elucidate in vitro some of the mechanisms by which rAAV2-sVEGFRv-1 exerts its therapeutic effects. Human umbilical vein endothelial cells (HUVECs) were infected with rAAV2-sVEGFRv-1 or a control virus vector in the presence of members of the VEGF family to identify potential binding partners via ELISA, which showed that VEGF-A, VEGF-B, and placental growth factor (PlGF) are all ligands of its transgene product.
