OBJECTIVES: We aimed to determine how the hemodynamic parameters of the superior mesenteric artery are affected in mesenteric panniculitis. METHODS: Twenty-one patients with a diagnosis of mesenteric panniculitis on computed tomography were evaluated with duplex Doppler sonography. The control group consisted 20 asymptomatic volunteers. The peak systolic velocity, end-diastolic velocity (EDV), resistive index (RI), pulsatility index (PI), blood flow volume, and body mass index were measured in the group of patients with mesenteric panniculitis, and the findings were compared with those of the control group...

OBJECTIVE: Prior studies have suggested a relationship between operative (Op) time and outcome after major vascular procedures. This study analyzed factors associated with Op time and outcome after carotid endarterectomy (CEA) in the Vascular Quality Initiative (VQI) registry. METHODS: Elective, primary CEAs without high anatomic risk or concomitant procedures from 2012 to 2015 in the VQI were analyzed (N = 26,327, performed by 1188 surgeons from 249 centers). Multivariable analysis was used to identify patient, procedure, and surgeon factors associated with Op time and major adverse events (MAEs), categorized as either technical (ipsilateral stroke, cranial nerve injury, reoperation) or cardiac (myocardial infarction, congestive heart failure, dysrhythmia requiring treatment, surgical site infection, and death)...

INTRODUCTION: Cerebrovascular accidents constitute the most common cause of disability all over the world. In India prevalence rate is 545 per 100000 and mortality rate is around 7.5 per thousand. Therefore the authors undertook a study on patients who underwent coronary artery bypass surgery (CABG). They were investigated for clinical and/or radiological evidence of cerebrovascular disease (CVD) with the aim to decide on early neurological intervention. PATIENTS AND METHODS: 210 patients who had undergone CABG were evaluated with neck vessel Doppler using high resolution duplex scanner system and computed tomography (CT) scan as well as MR angiogram (MRA) in addition to assessment of co morbid risk factors...

Skeletal muscle blood flow is attenuated in aged humans performing dynamic exercise, which is due, in part, to impaired local vasodilatory mechanisms. Recent evidence suggests that folic acid improves cutaneous vasodilation during localized and whole-body heating through nitric oxide-dependent mechanisms. However, it is unclear if folic acid improves vasodilation in other vascular beds during conditions of increased metabolism (i.e. exercise). The purpose of this study was to test the hypothesis that folic acid ingestion improves skeletal muscle blood flow in aged adults performing graded handgrip and plantar flexion exercise via increased vascular conductance...

In the clinic 60 patients were examined, in whom reconstructive operations on the main arteries were performed for obliterating atherosclerosis (OA) of the lower extremities vessels. Efficacy of impact of Plestazol (in a 200 mg/day dose) on neointima hyperpla- sia was studied. Clopidogrel (75 mg/day) was administered to patients of comparative group. Effective criteria for estimation of the migration-proliferation disorders state in endothelial dysfunction are concentration of the intercellular adhesion molecules (ICAM) and the basic factor of the fibroblasts growth (FGFb); morphological disorders in hyperplastic reactions of neointima - determination of thickness of "intima-media" complex in accordance to the ultrasound duplex scanning data...

Peripheral artery disease (PAD) is the most frequent cause for reduced perfusion in peripheral arteries. Patients with PAD have often manifestations of atherosclerosis in other vascular territories. Typical symptoms are intermittent claudication or rest pain and acral lesions in patients with critical limb ischemia. The majority of PAD patients are clinically asymptomatic; therefore, it makes sense to screen for PAD in patients with cardiovascular risk factors. The ankle brachial index (ABI) is regarded as an easy and cost-effective method for baseline diagnostics...

Atherosclerosis is a systemic disease with manifestations in multiple vascular beds. Ideal cardiovascular health (CVH) metrics relate to cardiovascular and cerebrovascular disease. However, the relation between ideal CVH metrics and asymptomatic polyvascular disease (polyVD) is unknown. We collected information on the 7 CVH metrics among 5,224 participants aged ≥40 years from 2010 to 2011. Intracranial artery stenosis, extracranial artery stenosis, and lower extremity artery disease were detected by transcranial Doppler, duplex sonography, and by calculating ankle-brachial index...

Sensitive detection of a low abundant protein is essential for biomedical research and clinical diagnostics. Herein, we develop a label-free colorimetric biosensor for the sensitive detection of recombinant human vascular endothelial growth factor-165 (VEGF165). This biosensor consists of an aptamer-based hairpin probe, an assistant DNA-trigger duplex and a linear template. In the presence of VEGF165, the specific binding of VEGF165 with the aptamer-based hairpin probe results in the opening of a hairpin probe and the opened hairpin probe subsequently hybridizes with the single-stranded region of the assistant DNA-trigger duplex to initiate the strand displacement amplification (SDA) to yield abundant triggers...
