BACKGROUND: Endovenous radio frequency ablation for small saphenous vein incompetence by and large appears to be superior and safer than conventional open surgery. Small saphenous vein ablation from approximately mid-calf to the point proximally where the small saphenous vein dives into the popliteal fossa is considered to be safe, as the sural nerve is in most cases separated from this segment of the small saphenous vein by the deep fascia. The outcome of the distal incompetent small saphenous vein remains unclear...

Persistent pain after iliac vein stenting is rare. Surgical removal of two oversized (20-mm) iliac vein stents was performed in a 36-year-old woman because of severe back pain of 2½ years' duration. Clamping or venotomy were not required for stent removal, which was done by extraction of each wire of the stent through small puncture wounds in the vein wall. Duplex scanning confirmed residual pseudointima obstructing the orifice of the right common iliac vein. The pseudointima was surgically removed. The patient recovered without complications, and her pain completely resolved...

OBJECTIVE: Spiral laminar flow was suggested as potentially the predominant arterial blood flow pattern many years ago. Computational fluid dynamics and flow rig testing have suggested there are advantages to spiral laminar flow. The aim of this study was to identify whether spiral laminar is the predominant flow pattern in a cohort of volunteers. METHODS: This study included 42 volunteers (mean age 66.8 years). Eleven arterial sites were examined, comprising bilateral examination of the common carotid artery, internal carotid artery, external carotid artery, common femoral artery, superficial femoral artery, and the infra renal aorta...

BACKGROUND: Open surgery and the retrograde endovascular approach via the distal left common carotid artery (LCCA) have some limitations in LCCA ostial stenosis treatment. The 'no touch' technique used in the renal artery was modified for this situation. METHODS: Fifteen selective LCCA stenosis patients were treated by the modified 'no touch' technique in the antegrade endovascular approach from March 2013 to March 2016. Thirteen underwent the transfemoral approach and the other two had the transbrachial approach due to a 'bovine aortic arch'...

Duplex scanning is utilised by many departments in the investigation of suspected DVT. NICE Guideline CG144 recommended repeat scanning for patients in whom the initial Wells score was 'likely' in the presence of a raised D-Dimer, following a normal first scan. Following implementation of this recommendation in our department there was a dramatic rise in the number of repeat scans being undertaken, all of which were negative for DVT. Introduction of an electronic message to the report, placing the onus back on the referring clinician to arrange repeat scan if deemed appropriate resulted in a fall in the number of scans being undertaken without impacting on patient outcome...
