The first accounts of measuring cerebral blood flow (CBF) in humans were made by Angelo Mosso in ~1880, who recorded brain pulsations in patients with skull defects. In 1890, Charles Roy and Charles Sherrington determined in animals that brain pulsations-assessed via a similar method used by Mosso-were altered during a variety of stimuli including sensory nerve stimulation, asphyxia, and pharmacological interventions. Between 1880 and 1944, measurements for CBF were typically relied on skull abnormalities in humans...

BACKGROUND: Although many grafts have been used for plaque incision with grafting (PIG) and penile prosthesis (PP) implantation, there is no evidence that favors 1 specific graft over another. AIM: To compare fibrin-coated collagen fleece (TachoSil; Baxter International, Deerfield, IL, USA) with porcine small intestinal submucosa (SIS; Cook Biotech, West Lafayette, IN, USA) as grafts. METHODS: From January 2007 to January 2015, 60 non-randomized consecutive patients affected by end-stage Peyronie disease underwent PIG and PP implantation (AMS 700CX; Boston Scientific, Marlborough, MA, USA)...

OBJECTIVE: Nationally, nonradiologists interpret an increasing proportion of lower extremity venous duplex ultrasound (LEVDU) examinations. We aimed to study day of week, site of service, and patient complexity differences in LEVDU services interpreted by radiologists versus nonradiologists. MATERIALS AND METHODS: Using carrier claims files for a 5% national sample of Medicare beneficiaries from 2012 to 2015, we retrospectively classified all LEVDU examinations by physician specialty (radiologist versus nonradiologist), day of week (weekday versus weekend), site of service, and patient Charlson Comorbidity Index (CCI) scores...

Several biologically active molecules including nutrients can affect the vascular endothelium which becomes dysfunctional and, as a consequence, predisposes to atherosclerosis. However, the impact of the intake of sodium and polyunsaturated fatty acids on carotid atherosclerosis in a population of elderly women has scarcely been studied. Our aim was to investigate the association between carotid intima-media thickness and atherosclerotic plaque and nutrient intake in asymptomatic elderly women. Carotid atherosclerosis was determined by duplex ultrasound in 108 elderly women...

Dissection of the internal carotid artery (ICA) accounts for 5% to 25% of ischemic strokes in young adults. We report a case of spontaneous recanalization of a traumatic ICA dissection in which carotid duplex (CDU) and transcranial color-coded duplex ultrasound (TCCD) were used. A 47-year-old male presented with intermittent episodes of headache, blurry vision, anisocoria, and loss of taste sensation following a whiplash injury while body surfing. Magnetic resonance angiogram (MRA) of the neck revealed absent flow in the cavernous ICA and a clot at the skull base...

Traumatic venous pseudoaneurysm is extremely rare. Only two cases of great saphenous venous (GSV) pseudoaneurysm have been reported. We present a case in which a gradually enlarged mass occurred at the calf after local injury. It was nonpulsatile and varied in size with posture. It was initially misdiagnosed by contrast MRI. Duplex ultrasound and surgical intervention eventually identified it as a GSV pseudoaneurysm. This case demonstrates the need for physicians to consider venous pseudoaneurysm as a possible diagnosis for nonpulsatile masses in patient with traumatic history, and to use Duplex ultrasound for adequate evaluation...

Penile curvature is a common urological disease. Tunical plication for correction of penile curvature has been much popularized being simpler, adjustable to avoid overcorrection, less bleeding, and less postoperative erectile dysfunction. This study aims to assess the results of modified 16-dot plication technique for correction of congenital and acquired penile curvature and avoidance of knot-associated complications. Eighteen patients underwent correction of their penile curvature using the modified 16-dot plication technique between January 2014 and October 2015...

INTRODUCTION: Popliteal artery entrapment is an uncommon syndrome, caused by extrinsic compression of the popliteal artery by muscular or tendinous structures. It occurs mainly in young individuals, with no atherosclerostic risk factors, and a mean age of presentation of 20 to 40 years, and has higher prevalence in males (83% of patients). Clinical presentation depends on the degree of arterial lesion, the most common being intermittent claudication, with critical ischemia being frequent...

BACKGROUND: Venous thromboembolism is a cause of morbidity and mortality in trauma patients. Chemoprophylaxis with low-molecular-weight heparin at a standardized dose is recommended. Conventional chemoprophylaxis may be inadequate. We hypothesized that a weight-adjusted enoxaparin prophylaxis regimen would reduce the frequency of venous thromboembolism in hospitalized trauma patients and at 90-day follow-up. METHODS: This prospective, randomized pilot study enrolled adult patients admitted to a level 1 trauma center between July 2013 and January 2015...

In infants and young children with suspicion of genitourinary tract anomalies, ultrasonography (USG) is usually the first imaging modality. Advantages of USG are well described. In the evaluation of complex congenital urogenital anomalies, ultrasound examination needs to be tailored according to the clinical suspicion and to yield maximum information. Primary megaureter is a congenital anomaly, which is associated with dilatation of ureter above an adynamic segment at the vesicoureteric junction (VUJ). Two different types are described in the literature: refluxing and obstructive...

The left internal thoracic artery (ITA) is currently an artery of choice for revascularization of coronary arteries. Ultrasonographic duplex scanning (USDS) and ultrasound Doppler flowmetry (UDF) are sequential techniques to control patency of the ITA at stages of rendering care for patients on restoring coronary blood flow. We compared two methods of measuring the volumetric blood flow velocity: by means of USDS and UDF. The obtained results were statistically processed. It was determined that transthoracic USDS and intraoperative UDF in the assessment of the volumetric blood velocity through the ITA in patients with coronary artery disease are comparable methods, provided the patients have similar parameters of central haemodynamics...

We describe a case of a 44 year-old man with a subcutaneous swelling in the left popliteal fossa. The patient complained pain posteriorly to the left knee since several months and presented with a saccular aneurysm of the left popliteal vein (PVA) with reflux clearly evidenced at duplex ultrasound scan (DUS), but in absence of thrombus inside and without clinical signs of embolism. The patient was treated surgically by aneurysmectomy with lateral venorrhaphy according to Aldridge technique and a duplex ultrasound scan after six months revealed a complete patency of the left popliteal vein...

BACKGROUND: Although unprovoked superficial venous thrombosis (SVT) has traditionally been considered a local, benign disorder, recent studies demonstrate that patients with SVT are at significant risk for deep venous thrombosis, pulmonary embolism, and other venous thromboembolism (VTE) events. Nevertheless, clinical management remains widely inconsistent. Moreover, patients with multiple, unprovoked SVTs of noncommunicating anatomic sites have not been previously described, and they may be at even increased risk for adverse outcomes...

OBJECTIVE: Radiofrequency ablation (RFA) is increasingly being employed for treatment of perforator vein insufficiency and venous ulcer healing. Previous studies have shown a closure rate of 60% to 80% in incompetent perforator veins (IPVs) with RFA. The purpose of the study was to determine the utility of a redo RFA for symptomatic recanalized perforators and to predict factors associated with recanalization. METHODS: A retrospective analysis of 642 procedures in 256 patients with venous insufficiency due to IPVs from 2009 to 2015 was conducted...
