PURPOSE: To report the use of adjunctive venography for the treatment of superficial venous reflux. METHODS: Two hundred consecutive patients (mean age 60.9 years, range 33-86; 128 women) with chronic venous disease underwent saphenous or perforator vein ablation in 268 limbs (305 venous trunks) guided by adjunctive venography and fluoroscopy in addition to ultrasound between October 2010 and May 2016. Intraprocedural venograms were independently evaluated by 2 vascular specialists to identify the presence of venous anomalies and the need for fluoroscopy-guided maneuvers to successfully complete venous ablation...

The development of high-performance biosensing platform is heavily dependent on the recognition property of the sensing layer and the output intensity of the signal probe. Herein, we present a simple and highly sensitive biosensing interface for DNA detection on the basis of graphene oxide nanosheets (GONs) directed in-situ deposition of silver nanoparticles (AgNPs). The fabrication process and electrochemical properties of the biosensing interface were probed by electrochemical techniques and scanning electron microscopy...

Despite advances in endovascular strategies, surgical infrainguinal lower limb revascularization remains the gold standard treatment for critical lower limb ischemia and disabling claudication.1 Maintaining patency of infrainguinal vein bypass grafts has been a challenging task for vascular surgeons as they are prone to developing stenosis which may precipitate failure of the bypass.2,3 Duplex ultrasound scanning has evolved as the investigation of choice to identify vein graft lesions but graft surveillance programs using this technique remain controversial...

BACKGROUND: Venous drainage from the leg is poorly understood, and it is difficult to quantify it hemodynamically. Attempts have been made using duplex ultrasound scanning and venous occlusion air plethysmography (APG). However, they have limited value in day-to-day clinical practice. This is because venous drainage measurements have never been validated successfully against increasing obstruction pressures. The hypothesis is that the novel gravitational venous drainage index (VDI) in milliliters/second is reduced in response to increasing venous obstruction, and the aim was to quantify this, using stepwise inflations of a thigh cuff...

BACKGROUND: Duplex ultrasound (DUS) is performed by the majority of physicians after endovenous ablation (EVA) of the great saphenous vein to screen for endovenous heat-induced thrombosis (EHIT) at the saphenofemoral junction extending into the femoral vein. Several factors should be considered in assessing the value and cost of routine DUS after EVA: the natural history of EHIT is poorly defined, the incidence appears low, and the majority are both asymptomatic and Kabnick type 2 (projecting only slightly into the femoral vein)...

Temporal artery is superficially exhibited and easily traumatized. Rarely, a minor and blunt trauma, especially in elderly who are under anticoagulants, can cause a pseudoaneurysm. Diagnosis should be based, primarily, on history and physical examination and secondarily on duplex ultrasound scanning which will lead to confirmation and preoperative planning. The therapeutical plan consists of surgical ligation and excision of the aneurysm. Surgery can be performed under local anesthesia with no postoperative major or minor complications...

Atherosclerotic Renal Artery Stenosis is a form or peripheral arterial disease that tends to affect older subjects with hyperlipidemia, history of tobacco use, and who have other coexistent forms of vascular insufficiency. An abdominal bruit on physical exam can be a helpful clue. Slowly progressive, it can lead to critical narrowing of the renal arteries which creates a cascade of events such as renin-angiotensin-aldosterone activation (RAAS), hypertension, acute pulmonary edema, and renal fibrosis. The hypertension is considered a secondary form and can even be resistant to multiple antihypertensives...

High resolution melting (HRM), with a high sensitivity to distinguish the nucleic acid species with small variations, has been widely applied in the mutation scanning, methylation analysis, and genotyping. For the aim of extending HRM for the evaluation of thermal stability of nucleic acid secondary structures on sequence dependence, we investigated effects of the dye of EvaGreen, metal ions, and impurities (such as dNTPs) on melting temperature (Tm ) measurement by HRM. The accuracy of HRM was assessed as compared with UV melting method, and little difference between the two methods was found when the DNA Tm was higher than 40°C...

A 76-year-old man who had undergone endovascular repair for an infrarenal aortic aneurysm, presented with a late type Ia endoleak 3 years after his operation. Deployment of an aortic cuff did not achieve a better seal at the proximal neck, and the aneurysm developed a rupture. We successfully treated the ruptured aneurysm using transcatheter Onyx embolization only. At 6-month and 1-year follow-ups with contrast-enhanced duplex scanning, no endoleak was seen and sac shrinkage was observed. Onyx is a relatively new liquid embolic agent that is slowly transformed into a solid state by contact with blood...

REVIEW
Gideon Nesher, Gabriel S Breuer
Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are both more common among people of North European decent than among Mediterranean people. Women are 2-3 times more commonly affected. Giant cell arteritis and PMR are extremely rare before age 50 years. Polymyalgia rheumatica may be "isolated" or associated with GCA. There is increased expression of inflammatory cytokines in temporal arteries of PMR patients, without overt histological evidence of arteritis. One-third of "isolated" PMR patients have vascular uptake in positron emission tomography (PET) scans, suggesting clinically unrecognized, "hidden" GCA...

BACKGROUND: Ankle-brachial pressure index-systolic (ABI-s) can be falsely elevated in the presence of calcified lower limb arteries in some diabetic patients and therefore loses its value in this cohort of patients. We aim at investigating the feasibility of using the diastolic (ABI-d) instead of ABI-s to calculate the ABI in diabetic patients with calcified limb arteries. METHODS: A total of 51 patients were chosen from the diabetic foot clinic. Twenty six of these patients had calcified leg arteries by Duplex scan (Group A) and 25 patients did not have calcifications in their leg arteries (Group B)...

Blunt trauma to the right proximal subclavian artery is uncommon and tends to be associated with pseudoaneurysm formation. We report a patient with right proximal subclavian artery pseudoaneurysm after blunt chest trauma following a motor vehicle accident. The condition was successfully treated with a combined insertion of a covered stent and carotid-carotid bypass as a hybrid procedure. Duplex scans at 6 month and 1 year follow-up documented good stent-graft positioning and no pseudoaneurysm recurrence.
