This study was supported by a research grant from the Clarivein  device manufacturer, Vascular Insights and an educational research grant from the Graham-Dixon Charitable Trust. Vascular Insights provided funding for Clarivein  devices, patient follow-up and duplex ultrasonography. Case funding was not used in this study. All trial particulars (design, data collection, analysis, discussion and data access) were performed independently of the funding bodies and the trial's research sponsor was Imperial College London.

Early results show that the mechanochemical ablation is less painful than the radiofrequency ablation procedure. Clinical and quality of life scores were similarly improved at one month. The long-term data including occlusion rates at six months and quality of life scores are being collected.

Obesity is an increasing burden on health-care globally. Significant obesity is presenting at a younger age, with pathology that has not been previously seen. This case report illustrates the catastrophic consequences which may occur when minor trauma occurs in a young person who suffers from morbid obesity. A 19-year-old woman with BMI 50 tripped over an uneven curb, and suffered complete dislocation of the knee with associated popliteal artery injury. She required femoro-popliteal bypass using vein. This case reports the youngest person to suffer from this injury and the first in the UK.

This review suggests marked variation in the management of popliteal fossa venous incompetence. There is a clear need for further research to clarify the role of ablation in the management of symptoms and skin changes.

Suture-based vascular closure devices are used in percutaneous endovascular procedures. However, failures are not uncommon. We have described our initial experience with two adjunct techniques to reinforce the suture-based vascular closure device (ProGlide; Abbot Vascular, Santa Clara, Calif) after percutaneous endovascular aneurysm repair. The threads of the ProGlide device (Abbot Vascular) were passed through a pledget with the help of a needle, which was secured to the puncture site to allow for traction compression. The use of the techniques can be helpful if the suture-based vascular closure devices fail to achieve immediate and complete hemostasis. The use of these adjuncts could reduce the incidence of closure-related complications after percutaneous endovascular procedures.
