Utility of post mortem MRI in definition of thrombus in aneurismatic coronary arteries due to incomplete Kawasaki Disease in infants

2016

Abstract Kawasaki disease (KD) is an acute, self-limited vasculitis of unknown etiology that primarily affects the coronary artery (CA) and presents in childhood. The characteristic coronary arterial lesion is an aneurysm, which may lead to thrombosis, dilatation, stenosis, and occlusion. Such an aneurysm is typically calcified and generally develops five or more years after the onset of acute KD. It becomes more noticeable after ten years. KD is sometimes difficult to diagnose because of the limited clinical features, especially in infants younger than 6 months old, where the clinical presentations often do not fulfill the diagnostic criteria for KD. We report a case of Incomplete Kawasaki…

Use of bivalirudin for heparin-induced thrombocytopaenia after thrombolysis in massive pulmonary embolism: a case report

2009

A 68-year-old man was referred to the emergency department 6 h after onset of sudden acute dyspnoea. Immediate ECG showed sinus tachycardia with the typical S1-Q3-T3 pattern and incomplete right bundle branch block. The echocardiogram showed the presence of mobile thrombus in the right atrium, a distended right ventricle with free wall hypokinesia and displacement of the interventricular septum towards the left ventricle. Lung spiral computed tomography (CT) showed bilateral pulmonary involvement and confirmed the picture of a thrombotic system in the right atrium and caval vein. Thrombolytic treatment with recombinant tissue plasminogen activator (rt-PA) and heparin (alteplase 10 mg bolus,…

A new thrombectomy catheter device (AngioJet) for the disruption of thrombi: An in vitro study

1999

In this study we examined a new thrombectomy catheter device. Different kinds of in vitro generated thrombi and cadaver thrombi were disrupted in test tubes. The mean disruption rate (and disruption time for 1 g of thrombus) was 225 +/- 65 mg/sec (5 +/- 2 sec) for whole-blood, 117 +/- 60 mg/sec (12 +/- 9 sec) for fibrin, 41 +/- 18 mg/sec (30 +/- 18 sec) for mixed, 70 +/- 42 mg/sec (17 +/- 5 sec) for unorganized, 45 +/- 8 mg/sec (22 +/- 4 sec) for partly, and 5 +/- 1 mg/sec (216 +/- 29 sec) for completely organized cadaver thrombi (P0.05). More than 99% of fragmented particles of whole-blood thrombi were 0-12 microm in diameter. The particle size of fibrin, mixed, and cadaver thrombi was sim…

Endovascular management of the deep venous thrombosis: A new challenging role for the endovascular specialist in 2020

2020

Over the last years, the endovascular approach to the management of the acute and chronic deep vein thrombosis (DVT) has gained more and more attention from the scientific community. DVT is the third most common cardiovascular disease after coronary heart disease and stroke, with classic treatment based on anticoagulation. Recent evidences have highlighted the risk of postthrombotic syndrome as high as 30%-50% in proximal ilio-femoral lesions, with irreversible clinical symptoms and impact on the quality of life of the population. Since 2000s, the new concept of thrombus removal in the acute phase has been supported by the introduction of different techniques based on the endovascular ablat…

Management of Lemierre Syndrome.

2022

Lemierre Syndrome is a rare form of septic thrombophlebitis of the head and neck veins, most typically of the internal jugular vein, which affects otherwise healthy adolescents and young adults after an oropharyngitis or other local infection. It is characterized by multiple septic embolization. Despite treatment, Lemierre Syndrome displays a high rate of in-hospital complications that include thrombus progression and a new peripheral septic embolization; moreover, it can be fatal or cause disabling sequelae. The mainstay of the treatment is antibiotic therapy; anticoagulation is often used, but its role is controversial. Surgical treatment is often necessary in case of peripheral septic le…

Frequency of thrombosis is higher in MPN patients who develop second cancer than in controls

2019

Introduction Malignancy can be heralded by unprovoked venous thromboembolism (VTE) but also by arterial thrombosis. To date it is unknown whether this association is present also in myeloproliferative neoplasms (MPN), in which arterial thrombosis is more frequent that venous thrombosis and solid tumors are reported with an increased frequency. The MPN-K nested case-control study addressed the impact of cytoreductive drugs on the risk of developing second cancer in MPN patients (Barbui T et al, Leukemia 2019); here we re-examined the study database to evaluate the frequency and type of vascular complications in MPN patients with second cancer excluding leukemia and to establish whether arter…

Tissue classification by texture and spectral analysis of intracoronary ultrasound radio-frequency data

2002

Imaging of vascular structures by intracoronary ultrasound allows in principal the recognition of different lesion types due to the echomorphology in the B-mode image. The subjective visual diagnosis is often difficult, especially the differentiation between thrombi and non-calcified plaque. The aim of this study was the extraction of features from the ultrasound radio-frequency signal for an objective characterization of coronary tissue. Methods of texture analysis and frequency analysis were used to differentiate red and white thrombi in vitro. Eight texture parameters of first and second order significantly differentiated red and white thrombi. The backscatter transfer function of red th…
