We report the unexpected transesophageal echocardiography (TEE) finding of a left atrial (LA) thrombus near the end of cardiopulmonary bypass and after deployment of an AtriClip (Atricure, Inc, Westchester, OH) in an 84-year-old man with atrial fibrillation and aortic stenosis undergoing aortic valve replacement and LA appendage ligation. TEE examination before cardiopulmonary bypass and deployment of the AtriClip had not shown a thrombus in the LA appendage. The heart was rearrested and thrombus was successfully removed through a left atriotomy...

INTRODUCTION: Renal vein or inferior vena cava (IVC) invasion by neoplastic thrombus in patients with renal cell carcinoma (RCC) is not an obstacle for radical oncological treatment. The aim of this study is to present our technical maneuvers for complete removal of the intracaval thrombus without compromising hemodymanic stability of the patient. MATERIALS AND METHODS: Between 2000 and 2014, 15 RCC patients with IVC involvement of levels I-III were treated with curative intent and were prospectively studied...

Lumbrokinases, a group of fibrinolytic enzymes extracted from earthworm, have been widely used to prevent and treat various cardiovascular diseases. They specifically target fibrin to effectively degrade thrombi without major side effects. Plant expression systems are becoming potential alternative expression platforms for producing pharmaceutical proteins. In this work, a lumbrokinase (PI239) was produced from a plant system. Both wild-type (WT) and plant codon-optimized (OP) PI239 gene sequences were synthesized and cloned into a geminivirus-based single-vector DNA replicon system...

REVIEW
Riten Kumar, Bryce A Kerlin
Abdominal venous thrombosis is a rare form of venous thromboembolic disease in children. While mortality rates are low, a significant proportion of affected children may suffer long-term morbidity. Additionally, given the infrequency of these thrombi, there is lack of stringent research data and evidence-based treatment guidelines. Nonetheless, pediatric hematologists and other subspecialists are likely to encounter these problems in practice. This review is therefore intended to provide a useful guide on the clinical diagnosis and management of children with these rare forms of venous thromboembolic disease...

Stroke is a dramatic complication of sickle cell disease (SCD), which is associated with cerebral vasculopathies including moya moya, intravascular thrombi, cerebral hyperemia, and increased vessel tortuosity. The spontaneous occurrence of these pathologies in the sickle cell mouse model has not been described. Here, we studied Townes humanized sickle cell and age-matched control mice that were 13 months old. We used in vivo two-photon microscopy to assess blood flow dynamics, vascular topology, and evidence of cerebral vasculopathy...

Arterial dissection is a rare complication after liver transplantation (LT). We report a case of extensive isolated spontaneous celiac trunk dissection (ISCTD) up to the proper hepatic artery, left gastric artery, and splenic artery after living donor liver transplantation. A 48-year-old woman with cryptogenic liver cirrhosis underwent living donor liver transplantation. Intraoperative and postoperative Doppler ultrasound revealed sufficient flow in the hepatic artery, portal vein, and hepatic vein. On postoperative day (POD) 10, Doppler ultrasound showed reduction of hepatic arterial flow...

A new biosensor for the real-time analysis of thrombus formation is reported. The fast and accurate monitoring of the individual thrombotic risk represents a challenge in cardiovascular diagnostics and in treatment of hemostatic diseases. Thrombus volume, as representative index of the related thrombotic status, is usually estimated with confocal microscope at the end of each in vitro experiment, without providing a useful behavioral information of the biological sample such as platelets adhesion and aggregation in flowing blood...

Hepatocellular carcinoma carries a high risk of invasion of the portal vein. Neoplastic and bland portal vein thrombi discrimination is of great clinical significance for determining the therapeutic approach, predicting survival, and assessing candidates for liver transplantation. F-FDG PET/CT may be helpful in discriminating between malignant and portal vein thrombi. We present the case of a 61-year old man who presented with hepatocellular carcinoma with portal vein involvement. F-FDG PET/CT has a role in differentiating malignant from benign portal vein thrombosis...

WHAT IS KNOWN AND OBJECTIVE: Free-floating thrombi in the right heart occur in a subset of patients with pulmonary embolism with high rates of mortality if untreated. Treatment of choice is controversial and likely patient specific as studies have failed to consistently show a significant difference in mortality between options. CASE SUMMARY: We present a case of a 45-year-old female with a mobile right heart thrombus treated with ultra-slow, low-dose t-PA infusion in combination with heparin...

INTRODUCTION: The specific protein composition of stroke-causing emboli is unknown. Because ischemic stroke has a varied etiology, it is possible that the composition of the thrombus from which an embolus originated will have distinctive molecular characteristics reflective of the underlying pathophysiology. We used mass spectrometry to evaluate the protein composition of retrieved emboli from patients with differing stroke etiologies and correlated the protein levels to serum predictors of atherosclerosis...

Atherosclerosis is the major underlying pathology of cardiovascular disease (CVD). The risk for CVD is increased in women with a history of preeclampsia. Multiple studies have indicated that accelerated atherosclerosis underlies this increased CVD risk. Furthermore, it has been suggested that endothelial dysfunction and inflammation play an important role in the increased CVD risk of women with preeclampsia. Rupture or erosion of atherosclerotic plaques can induce the formation of thrombi that underlie the onset of acute clinical CVD such as myocardial infarction and stroke...

Vascular smooth muscle cells (VSMCs) represent important modulators of plaque stability in advanced lesions. We previously reported that loss of small proline-rich repeat protein 3 (Sprr3), leads to VSMC apoptosis in a PI3K/Akt-dependent manner and accelerates lesion progression. Here, we investigated the role of Sprr3 in modulating plaque stability in hyperlipidemic ApoE-/- mice. We show that loss of Sprr3 increased necrotic core size and reduced cap collagen content of atheromas in brachiocephalic arteries with evidence of plaque rupture and development of intraluminal thrombi...

Renal complications from snakebite result in high mortality and morbidity. Acute kidney injury (AKI) occurs in 5-30% of cases. Renal manifestation could include acute tubular necrosis, cortical necrosis, interstitial nephritis, glomerulonephritis, and vasculitis. We present a case of thrombotic microangiopathy (TMA) resulting in renal cortical necrosis. Renal biopsy showed fibrin thrombi in glomeruli and arterioles with cortical necrosis. Our patient progressed to end-stage renal disease.

Nonvalvular atrial fibrillation (AF) is the most frequent arrhythmia with a prevalence of 1%-2% in the general population. Its prevalence increases with age and its diagnosis benefits of improvement and simplification of technologies for its detection. Today, AF affects approximately 7% of individuals age>65years and 15%-20% of octogenarians. Due to stasis and activation of coagulation in a fibrillating atrium, patients are at increased risk of thromboembolism, in particular ischemic stroke, with an overall stroke risk of 5% per year...

Thrombotic cardiovascular disease, including acute myocardial infarction, ischemic stroke, and venous thromboembolic disease, is the leading cause of morbidity and mortality worldwide. While reperfusion therapy with thrombolytic agents reduces mortality from acute myocardial infarction and disability from stroke, thrombolysis is generally less effective than mechanical reperfusion and is associated with fatal intra-cerebral hemorrhage in up to 2-4% of patients. To address these limitations, we propose the tobacco mosaic virus (TMV)-based platform technology for targeted delivery of thrombolytic therapies...

An EIM (ethanol infusion into the vein of Marshall [VOM]) provoked a fatal complication in a chronic hemodialysis patient. Autopsy revealed a lacerated VOM covered with thrombi as the only potential cause. The EIM caused vascular damage and clots resulting in myocardial necrosis and interstitial bleeding around the lacerated VOM.
