INTRODUCTION: Transcranial color-coded duplex sonography (TCCS) may help guide multimodal monitoring in the neurocritical setting. It may provide indirect information about intracranial hypertension, such as midline shift, third ventricle width, and peri-mesencephalic cistern obliteration. We aim to assess the agreement between brain computed tomography scan (CT scan) and TCCS in traumatic brain injury (TBI) patients. METHODS: In this retrospective cross-sectional observational study, TCCS was performed within 6 h before a brain CT scan...

Scanning for mutations by DNA melting analysis (DMA) is based on asymmetric PCR followed by the melting of duplexes formed by single-stranded amplicons with TaqMan probes. The method is optimally suited for clinical genetic testing; it is easy to perform, high-throughput, and sensitive. The detection limit of mutant alleles by the DMA method is about 3%, which is much higher than the sensitivity of Sanger sequencing. In addition, the DMA method is realized in a closed-tube format, while 2-h assay is carried out in a single tube without any intermediate or additional procedures thereby minimizing the risk of cross contamination of the samples...

OBJECTIVE: Currently, lymphedema (LED) is typically diagnosed clinically on the basis of a patient's history and characteristic physical findings. Whereas the diagnosis of LED is sometimes confirmed by lymphoscintigraphy (LSG), the technique is limited in both its ability to identify disease and to guide therapy. Recent advancements provide opportunities for new imaging techniques not only to assist in the diagnosis of LED, based on anatomic changes, but also to assess contractile function and to guide therapeutic intervention...

INTRODUCTION: Bilateral common iliac artery (CIA) aneurysm (CIAA) is a rare entity. In the past decade, different endovascular approaches have been adopted for patients with several comorbidities or unfit for open repair (OR). Recently, the use of iliac branch stent graft has been proposed, resulting in satisfactory patency rates and decrease in morbidity. Currently, according to instruction for use, the iliac branch stent graft is to be used with aortobi-iliac stent graft conjunction...

REVIEW
Olivia M McBRIDE, Roderick T Chalmers
Despite advances in endovascular strategies, surgical infrainguinal lower limb revascularization remains the gold standard treatment for critical lower limb ischemia and disabling claudication. Maintaining patency of infrainguinal vein bypass grafts has been a challenging task for vascular surgeons as they are prone to developing stenoses which may precipitate failure of the bypass. 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...
