BACKGROUND AND PURPOSE Quantitative magnetic resonance angiography (Q-MRA) enables direct measurement of volume flow rate (VFR) of intracranial arteries. We aimed to evaluate the collateral flows in internal carotid artery (ICA) occlusion with primary collateral pathway via circle of Willis using Q-MRA, and to compare them between patients who recently developed ipsilateral symptomatic ischemia...

Patients with diabetes, in particular patients with type 2 diabetes, are at a 2- to 4-fold higher risk of cardiovascular mortality compared with their nondiabetic peers. Patients with diabetes are also more likely to have silent ischemia and less likely to survive a myocardial infarction than nondiabetic patients. Recent studies with electron beam computed tomography (EBCT) have shown that subc...

Chronic superior mesentery ischemia often presents a clinically asymptomatic diffuse atherosclerotic process. There are no compelling recommendations on the benefits of early revascularization strategy besides antithrombotic prophylaxis and statin treatment. Conversely, long-term prevalence of symptomatic cases in surgical patient cohorts is rarely reported in the literature. Acutization of chr...

Intestinal malrotation is defined as an alteration in the rotation and fixation of intestine during fetal stage. It can present with a wide clinical spectrum ranging from acute volvulus to chronic duodenal obstruction. Its presentation therefore also very varied, asymptomatic patients whom diagnosis be made finding, extremely serious symptoms such midgut volvulus. Midgut most severe manifesta...

O ur understanding of chronic stable angina is gradually expanding, and two theories have developed in recent years. First, in patients with chronic stable angina, residual coronary flow reserve can be modulated to an important extent by dynamic changes in the caliber of pliable coronary artery stenoses with preserved muscular media.' This theory, coupled with the evidence of the remarkable eff...

Patients with celiac artery stenosis often remain asymptomatic due to formation of extensive collateral pathways. Hepatic or anastomotic ischemia may occur when the gastroduodenal artery and these collaterals are ligated during pancreaticoduodenectomy. Here, we present a patient with severe atherosclerotic disease of the celiac axis who successfully underwent pancreaticoduodenectomy with aorto-...

Purpose. Diabetic patients have a high risk for cardiovascular events. The role of myocardial perfusion imaging was investigated in asymptomatic diabetic patients to evaluate short-term prognosis in a Japanese population. Methods. A total of 506 asymptomatic patients ≥50 years of age who had carotid artery maximum intima-media thickness ≥1.1mm, urinary albumin excretion of ≥30mg/ g creatinine, ...

Abstract: Lower extremity peripheral artery disease (PAD) is frequently underdiagnosed, in part because of the wide variety of leg symptoms manifested by patients with PAD and in part because of the high prevalence of asymptomatic PAD. In primary care medical practices, 30% to 60% of patients with PAD report no exertional leg symptoms and ≈45% to 50% report exertional leg symptoms that are not ...
