The present study aimed to investigate the effect of the expression of interleukin (IL)‑18 and related markers on deep venous thrombosis (DVT) to examine their correlation. Sprague‑Dawley rats of different models were established and were randomly assigned into three groups. The expression of IL‑18, nuclear factor (NF)‑κB and von Willebrand factor (vWF) were detected in blood samples. The inferior vena cava (IVC) was ligated to establish the DVT model. Rat IL‑18 overexpression and inhibition vectors were constructed...

Tumor thrombus in the portal vein can rarely originate from gastric cancer via hematogenous spread, with only few case reports published in the literature. Isolated superior mesenteric vein tumor thrombus in gastric cancer has not been previously reported. A 61-year-old male patient who had undergone distal gastrectomy and gastroenterostomy for gastric ulcer 20 years ago was diagnosed with an obstructive tumor originating from the gastroenterostomy anastomosis site on upper gastrointestinal endoscopy that was performed for complaints of fatigue, oral feeding problems, and anemia...

Spindle cell hemangioma (SCH) is a unique benign vascular lesion. We present a case of SCH in the upper lip of a 41-year-old woman. A submucosal nodular mass 30 × 20 mm in size was observed in the left upper lip. The mass developed 5 years earlier and enlarged after repeated ethanol injections. The mass was elastic firm, mobile, bluish in color, and well demarcated in magnetic resonance imaging. Under the clinical diagnosis of hemangioma, surgical excision was performed under local anesthesia. Microscopically, the lesion was composed of irregular cavernous spaces and multiple solid cellular areas...

Superb microvascular imaging (SMI) reduces motion artifacts significantly and allows visualization of low-velocity blood flow in vessels; thus, thrombi are clearly demonstrated compared to conventional B-mode and color Doppler imaging. Ultrasonographic images of the lower extremities of a 69-year-old woman with acute ischemic stroke complicated with deep vein thrombosis (DVT) are presented. Because SMI allows visualization of low-velocity blood flow, echo contrast between the thrombus and the surrounding flow makes it possible to clearly visualize the thrombus...

BACKGROUND: Septic pulmonary embolism (SPE) is a rare disorder caused by metastasis of infectious thrombi to the lungs. Most commonly, this occurs as a result of infectious endocarditis. This clinical entity may easily be confused for more common and less mortal diagnoses such as pneumonia, bronchitis, or pulmonary embolism. CASE REPORT: A 47-year-old woman presented in respiratory distress with a complaint of cough productive of rusty sputum, shortness of breath, and pleuritic chest pain...

Central venous catheter use is common among patients undergoing haemodialysis. Catheter related vascular thrombosis is a frequent complication, which results in catheter dysfunction. This may eliminate the affected vein as a potential route of vascular access and leads to significant morbidity of the limbs involved. Despite increasing prevalence, there is a dearth of evidence-based guidelines for managing such catheter related thrombi, often leading to treatment dilemmas in clinical practice. Minimizing the use of central venous catheters for haemodialysis remains the best approach in preventing such adverse complications...

Pulmonary embolism (PE) is caused by emboli, which have originated from venous thrombi, travelling to and occluding the arteries of the lung. PE is the most dangerous form of venous thromboembolism, and undiagnosed or untreated PE can be fatal. Acute PE is associated with right ventricular dysfunction, which can lead to arrhythmia, haemodynamic collapse and shock. Furthermore, individuals who survive PE can develop post-PE syndrome, which is characterized by chronic thrombotic remains in the pulmonary arteries, persistent right ventricular dysfunction, decreased quality of life and/or chronic functional limitations...

BACKGROUND: Oral anticoagulation (OAC) is prescribed for left atrial thrombi (LAT) in non-rheumatic atrial fibrillation (AF) and/or atrial flutter (AFL). The study objective was to review the existing evidence regarding LAT resolution in non-rheumatic AF and/or AFL with OAC agents. METHODS: Data sources included PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) between January 1, 1991 and February 1, 2017. English-language studies that assessed LAT resolution with OAC agents in subjects with non-rheumatic AF and/or AFL, by serial transesophageal echocardiography (TEE), and with follow-up times ≥3 weeks and < 1 year were selected...

PURPOSE: In mechanical thrombectomy (MT) for ischemic stroke, endothelial cells (ECs) from intracranial blood vessels adhere to the stent retriever device and can be harvested. However, understanding the molecular biology and the role of the endothelium in different pathological conditions remains insufficient. The purpose of the study was to characterize and analyze the molecular aspect of harvested ECs using cell culture and transcriptomic techniques in an MT swine model relevant to clinical ischemic stroke...

The space-filling fibrin network is a major part of clots and thrombi formed in blood. Fibrin polymerization starts when fibrinogen, a plasma protein, is proteolytically converted to fibrin, which self-assembles to form double-stranded protofibrils. When reaching a critical length, these intermediate species aggregate laterally to transform into fibers arranged into branched fibrin network. We combined multiscale modeling in silico with atomic force microscopy (AFM) imaging to reconstruct complete atomic models of double-stranded fibrin protofibrils with γ-γ crosslinking, A:a and B:b knob-hole bonds, and αC regions-all important structural determinants not resolved crystallographically...

This review tries to answer the following 15 questions: Is atherosclerosis a systemic or a regional disease? Is atherosclerosis in any particular region focal or diffuse? What is the quantity of atherosclerotic plaques in endarterectomy specimens of the right coronary artery in patients undergoing coronary artery bypass grafting (CABG) compared to that in the right coronary artery in patients with fatal coronary artery disease? How do the units used for measuring arterial narrowing by angiography compare to the units used for measuring arterial narrowing at necropsy? What do atherosclerotic plaques consist of in coronary arteries in patients with fatal coronary disease? What is the quantity of atherosclerotic plaque in bypassed -vs- non-bypassed native coronary arteries in patients dying early (<60 days) or late (>60 days) after coronary artery bypass grafting? What is the frequency of acute coronary lesions and multi-luminal channels at necropsy in patients with unstable angina pectoris, sudden coronary death, and acute myocardial infarction? What is the mechanism of luminal widening by angioplasty in the coronary arteries? What observations suggest that atherosclerotic plaques are the result at least in part of organization of thrombi? Is atherosclerosis a multifactoral or a unifactoral disease? What characteristics distinguish carnivores and herbivores? What are reasonable guidelines for whom to treat with lipid-altering agents? What is the rule of 5 and the rule of 7 in statin therapy? What is the effect of lipid lowering drug therapy on coronary luminal narrowing? What are some requisites for a healthy life?...

A venous tumor thrombus (VTT) is a potentially lethal complication of renal cell carcinoma (RCC) but virtually nothing is known about the underlying natural history. Based on our observation that venous thrombi contain significant numbers of viable tumor cells, we applied multiregion whole exome sequencing to a total of 37 primary tumor and VTT samples including normal tissue specimens from five consecutive patients. Our findings demonstrate mutational heterogeneity between primary tumor and VTT with 106 of 483 genes (22%) harboring functional SNVs and/or indels altered in either primary tumor or thrombus...

An eight-year-old girl with myelodysplastic syndrome (refractory cytopenia) received a bone marrow transplant (BMT) from an unrelated donor because of immunosuppressive therapy failure. Following administration of foscarnet for cytomegalovirus reactivation at day40 post-BMT, serum creatinine increased, and proteinuria, hematuria, and hypertension gradually exacerbated and became prolonged. However, neither schistocytosis nor other organ damage was evident. At six months post-BMT, renal biopsy revealed diffuse glomerular damage with glomerular lobulation, a double contour of the glomerular basement membrane, erythrocyte congestion and thrombi in the glomerular endocapillaries, and mesangiolysis, confirming the diagnosis of transplantation-associated thrombotic microangiopathy (TA-TMA)...

Formation of thrombosis is mainly associated with dysfunctions of endothelial cells. NaoXinTong capsule (NXT), a traditional Chinese medicine, has been demonstrated multiple protective effects on vascular systems. However, it is unknown the effect of NXT on thrombosis. In this study, we determined if NXT can inhibit carrageenan-induced thrombosis and the underlying mechanisms. Two days after carrageenan injection, severe thrombi were found in blood vessels of mouse tail and liver. In contrast, thrombi were substantially reduced by NXT treatment, and the reduction was associated with reduced serum tumor necrosis factor α and P-selectin levels...

The left atrial appendage (LAA) is a complex and heterogeneous protruding structure of the left atrium (LA). In atrial fibrillation (AF) patients, it is the location where 90% of the thrombi are formed. However, the role of the LAA in thrombus formation is not fully known yet. The main goal of this work is to perform a sensitivity analysis to identify the most relevant LA and LAA morphological parameters in atrial blood flow dynamics. Simulations were run on synthetic ellipsoidal left atria models where different parameters were individually studied: pulmonary veins (PV) and mitral valve (MV) dimensions; LAA shape; and LA volume...

Left ventricular thrombi are mostly seen in the akinetic segments of left ventricle and warfarin is the golden standard treatment. In our case, a 67-year-old male patient with ischemic dilated cardiomyopathy and atrial fibrillation was under warfarin treatment, but due to fluctuations in international normalized ratio, warfarin was discontinued and changed to rivaroxaban (20 mg once a day). He had a fixed thrombus measuring 1.80 × 1.12 cm2 in the left ventricle under warfarin treatment before rivaroxaban use...

Five calves that had shown neurological symptoms within 9 days after birth were histopathologically diagnosed as encephalomalacia. Two calves showed bilateral laminar cerebrocortical necrosis and neuronal necrosis in the corpus striatum and hippocampus. Since the distributional pattern of the lesions was consistent with that of global ischemia in other species, the lesions were probably hypoxic/ischemic encephalopathy consistent with the history of dystocia and perinatal asphyxia. One calf also showed bilateral laminar cerebrocortical necrosis...
