international travel has become increasingly common and accessible, hence, about two billion passengers undertake international and domestic air travel each year. venous thromboembolism (vte) is a serious public health disorder which may occur following prolonged travel, especially after air travel. a direct relation between vte development and prolonged travels has been documented, while some ...
BACKGROUND Intraprocedural rupture and thrombus formation are serious complications during coiling of ruptured intracranial aneurysms, and they more often occur in patients with anterior communicating artery (ACoA) aneurysms. OBJECTIVE To identify independent predictors of intraprocedural rupture and thrombus formation during coiling of ruptured ACoA aneurysms. METHODS Between January 2008 ...
The relationship between left ventricular thrombus and left ventricular dynamics in dilated cardiomyopathy (DCM) was studied by echocardiography and postmortem examination. The subjects were 57 patients with DCM, 40 were survival patients examined by echocardiography and 17 were autopsy patients. Systemic or pulmonary embolism occurred in 10 of 57 patients, 4 of 40 survival patients and 6 of 17...
The degree of thrombus resolution directly indicates the effectiveness of a thrombolytic drug. We investigated the degree of thrombus resolution and factors associated with thrombus resolution after intravenous (IV) recombinant tissue plasminogen activator (rt-PA) using thin-section noncontrast computed tomography (NCT). Thin-section NCTs were performed before and immediately after IV rt-PA inf...
BACKGROUND Stent thrombosis (ST) is a rare but serious complication following percutaneous coronary intervention. Analysis of thrombus composition from patients undergoing catheter thrombectomy may provide important insights into the pathological processes leading to thrombus formation. We performed a large-scale multicentre study to evaluate thrombus specimens in patients with ST across Europe...
OBJECTIVES To evaluate the role played by biomechanical and geometrical parameters of endoluminal thrombus and of aortic wall on abdominal aortic aneurysm (AAA) behaviour. MATERIALS AND METHODS Tensile tests on 21 AAA thrombus specimens from six patients undergoing AAA repair and numerical evaluation of aneurysmal aortic wall stress and strain distribution. Parameters of the analysis were lum...
Portal vein thrombus has been detected in patients with liver cirrhosis, pancreatitis, ulcerative colitis, septicemia, myeloproliferative disorder, and neoplasm. The formation of portal tumor thrombus by hepatocellular carcinoma is well recognized, because of its high incidence, and subsequent development of portal hypertension such as rupture of varices, ascites and liver failure indicates the...
OBJECTIVE Deep venous thrombosis is a common vascular problem with long-term complications including post-thrombotic syndrome. Post-thrombotic syndrome consists of leg pain, swelling and ulceration that is related to incomplete or maladaptive resolution of the venous thrombus as well as loss of compliance of the vein wall. We examine the role of metalloproteinase-9 (MMP-9), a gene important in ...
Intracoronary thrombus is regarded as a potentially important factor in the etiology of unstable angina, but the incidence of intracoronary thrombus in unstable angina has not been clearly defined. To determine the occurrence of intracoronary thrombus during ongoing angina pectoris, coronary angiography was performed during spontaneous ischemic attacks in 37 patients with prolonged rest angina....
background rheumatismal mitral stenosis is less common today than it was several decades ago, but it is a common cause of mitral stenosis (ms) in the developing world. mitral valve stenosis symptoms include fatigue, palpitations, and shortness of breath especially with exertion. objectives the purpose of this prospective study was to determine the incidence of left atrial (la) thrombus and the ...
