CONCLUSION:
Injection of CA is feasible for closure of superficial veins in animal models.
Vein closure is achieved via an inflammatory process which ultimately leads to
fibrosis

Methods: Incompetent great saphenous veins in 38 paMents were embolized by cyanoacrylate bolus injecMons under ultrasound guidance without the use of perivenous tumescent anesthesia or graduated compression stockings. Follow-­‐up was performed over a period of 24 months. Result: Of 38 enrolled paMents, 36 were available at 12 months and 24 were available at 24 months follow-­‐up. Complete occlusion of the treated great saphenous vein was confirmed by duplex ultrasound in all paMents except for one complete and two parMal recanalizaMons observed at, 1, 3 and 6 months of follow-­‐up, respecMvely. Kaplan-­‐Meier analysis yielded an occlusion rate of 92.0% (95% CI 0.836–1.0) at 24 months follow-­‐up. Venous Clinical Severity Score improved in all paMents from a mean of 6.1±2.7 at baseline to 1.3±1.1, 1.5±1.4 and 2.7±2.5 at 6, 12 and 24 months, respecMvely (p<.0001). Edema improved in 89% of legs (n1⁄434) at 48 hours follow-­‐up. At baseline, only 13% were free from pain. At 6, 12 and 24 months, 84%, 78% and 64% were free from leg pain, respecMvely. Conclusions: The first human use of endovenous cyanoacrylate for closure of insufficient great saphenous veins proved to be feasible, safe and effecGve. Clinical efficacy was maintained over a period of 24 months. Visual Comparison of Ultrasound and Histology

The evalua>on of a novel technique to treat saphenous vein incompetence: preclinical animal study to examine safety and efficacy of a new vein occlusion device. Farber A1, Belenky A, Malikova M, Brenner O, Brandeis Z, Migdal M, Orron D, Kim D. Abstract OBJECTIVES: We tested a novel technique to treat great saphenous vein (GSV) incompetence in an animal model. METHODS: V-­‐block (VVT Medical Ltd, Kfar Saba, Israel), an occlusion device composed of a niMnol frame and anchoring hooks, was percutaneously deployed at the saphenofemoral juncMon in 12 sheep. Four of the 12 sheep were treated with adjuncMve liquid sclerotherapy. Animals underwent duplex ultrasound, venography and histopathological evaluaMon immediately posMmplantaMon at 30, 60 and 90 days. RESULTS: V-­‐block was successfully deployed in all animals without adverse events. There was no device migraMon at follow-­‐up. Histopathological analysis demonstrated V-­‐block to be lodged within the GSV and surrounded by fibrous Mssue in all samples. ObliteraMon of the GSV lumen, widespread inMmal loss and mulMfocal medial smooth muscle loss was noted. CONCLUSIONS: In this animal study V-­‐block was deployed without complicaMons, remained in stable posiMon and led to GSV occlusion. This device has promise for future use in humans. V-­‐block
IniMal trial results in humans. Fisy paMents were studied; Early occlusion rate of 90 %. 46 followed to an average of 4.6 months. •  There was 100% occlusion at this early stage. •  No DVT reported, and 1 paMent had superficial thrombophlebiMs. •  Device sMll in very early development, and further studies are planned •

•  We demonstrated that the 1470-nm wavelength
endovenous laser system could not close saphenous
veins without use of anesthesia.
•  Closure with a dramatic reduction in energy when compared to a
980-nm wavelength control demonstrated a marked reduction in
postoperative pain and ecchymosis; this implies that vein-wall
perforations are minimized with this system.

Despite early success of tumescent-less
therapies, Thermal Injury with RF and EVLA has
shown to be:
•  Effective.
•  Low risk of complication.
•  Proven track record.
•  Long term use has optimized the thermal injury
technique.
Why mess with success?

Summary
• New evolving technique are designed to eliminate the need for Tumescent anesthesia. • Thermal remains as a safe and effecMve means of venous insufficiency treatment. • Complex venous anatomy demands mulMple tools available. What does the future hold?
