Enormous hemangiosarcoma of the heart
1994
This report describes a 26-year-old patient with hemangiosarcoma of the heart and summarizes the clinicopathological features in previous reports of patients with cardiac angiosarcoma. The patient was admitted to our hospital because of a syncope and one episode of nocturnal dyspnea and hemoptysis. In his history he complained of progressive weakness and loss of weight over the past 2 months. Echocardiography and computed tomography of the chest showed inhomogeneous masses in the pericardial cavity completely surrounding the heart and involving the ascending aorta and the superior vena cava. Histological examination of the tissue obtained from the mass by fine needle technique revealed a po…
Home parenteral nutrition-associated thromboembolic and bleeding events: results of a cohort study of 236 individuals
2016
UNLABELLED Essentials Sparse or outdated studies focus on thrombotic and bleeding risk in home parenteral nutrition (HPN). 236 HPN patients followed at a single center for a total of 684 patient-years were evaluated. Rates of venous thrombosis and major bleeding, and prevalence of vena cava syndrome are provided. Anticoagulants might reduce thrombosis risk, but population-specific safety concerns remain. SUMMARY Background Home parenteral nutrition (HPN) is necessary for patients with intestinal failure. Recurrent catheter-related thrombosis (CRT) is common, leading to infectious complications, pulmonary embolism, vascular access loss and intestinal transplantation. The efficacy and safety …
A case report of pulmonary vein isolation performed in a patient with polysplenia and interrupted inferior vena cava
2021
Abstract Background Pulmonary vein isolation (PVI) has entrenched itself as one of the main approaches for the treatment of paroxysmal symptomatic atrial fibrillation (AF). Pulmonary vein isolation prevents focal triggers from pulmonary veins from initiating AF paroxysms. As standard—PVI is performed through the inferior vena cava (IVC) approach, through the femoral vein. However, there are conditions when this approach is not appropriate or is not available. Case summary We report a case of a 53-year-old male who was referred to Pauls Stradins Clinical University Hospital for PVI due to worsening AF. Due to the rare anatomical variant of the venous system, the standard approach to PVI coul…
Pharmacokinetics of methylmethacrylate monomer during total hip replacement in man.
1988
The concentration of methylmethacrylate monomer (MMA) in the blood stream after implantation of the components of 15 total hip prostheses using bone cement was determined in the pulmonary artery, the radial artery, and the superior vena cava after cement application, and correlated with the observed drop in blood pressure and the increase in the pulmonary arterial pressure. In all samples MMA was found. The values ranged from 0.02 micrograms/ml to 59 micrograms/ml. The mean maximum value after implantation of the stem was measured to be 7.8 micrograms/ml in the pulmonary artery, 4.6 micrograms/ml in the radial artery, and 1.75 micrograms/ml in the superior vena cava. After implantation of t…
Mediastinal syndrome from plasmablastic lymphoma in human immunodeficiency virus and human herpes virus 8 negative patient with polycythemia vera: a …
2017
Background: Plasmoblastic lymphoma is a rare and aggressive subtype of diffuse large B cell lymphoma, which occurs usually in the jaw of immunocompromised subjects. Case presentation: We describe the occurrence of plasmoblastic lymphoma in the mediastinum and chest wall skin of an human immunodeficiency virus-negative 63-year-old Caucasian man who had had polycytemia vera 7 years before. At admission, the patient showed a superior vena cava syndrome, with persistent dyspnoea, cough, and distension of the jugular veins. Imaging findings showed a 9.7 × 8 × 5.7 cm mediastinal mass. A chest wall neoformation biopsy and ultrasound-guided fine-needle aspiration biopsy of the mediastinal mass allo…
Persistent Left Superior Vena Cava Significance in Prenatal Diagnosis—Case Series
2022
The persistent left superior vena cava (PLSVC) is a congenital heart anomaly reported in 0.3–0.5% of the general population and can be associated with congenital heart diseases in up to 8% of cases. Prenatal identification of PLSVC is important to prompt an extended cardiac and extracardiac fetal examination. We retrospectively reevaluated anomaly scans performed in our unit in a 2-year interval according to the national guidelines to evaluate the incidence of PLSVC and its association with prenatal morbidity. In our population, the incidence of PLSVC was 0.31%, and we found a low association with cardiac and extracardiac anomalies. The standard sections (three-vessel and trachea view, four…
From suspicion of angioedema to the diagnosis of lung cancer
2020
Angioedema is a localized and self-limiting oedema of the subcutaneous and submucosal tissue. Case presentation: 73-year-old man was admitted to the Division of Allergology with the diagnosis of angioedema. Detailed physical examination led to the suspicion of superior vena cava syndrome with secondary face swelling. Biopsy revealed metastasis of small cell carcinoma in superclavicular lymph nodes. Conclusions: Facial swelling, especially recurrent and non-inflammatory, is often, but not always caused by angioedema. Insightful differential diagnosis is crucial before making the final one.
Artefaktreduzierung bei der Lungenemboliediagnostik mittels Spiral-CT unter Verwendung eines Kochsalzbolus
2001
nary Arteries Using a Saline Push. Purpose: To improve the diagnostic efficacy of bolus-enhanced spiral CT (SCT) in the detection of pulmonary embolism using a saline push immediately after bolus injection of the contrast medium. Patients and Methods: The study included 90 patients with suspected acute or chronic pulmonary embolism. The CT scan was performed in a caudocephaled direction. In Group I (n=60) we applied a bolus contrast injection (120 ml, 3 ml/s, 300 mg J/ml), after a median delay of 25 s. Group II (n = 30) had the same contrast injection which was immediately followed by an additional saline push (60 ml, 2 ml/s). Streak artifacts originating from high contrast concentrations i…
Gradual angioplasty and stent implantation to treat complete superior vena cava occlusion after Mustard procedure
1996
A 16-year-old male was admitted with complete occlusion of the superior vena cava pathway 14 years after Mustard procedure for transposition of the great arteries. From a left subclavian vein approach, the atretic vein segment was perforated using a straight guidewire, and was followed by sequential balloon dilation. Implantation of a 30 mm Palmaz-stent through a femoral vein approach resulted in a widely patent channel of the vena cava superior into the systemic venous atrium. © 1996 Wiley-Liss, Inc.
Endovascular management of a large aneurysm of the superior vena cava involving internal thoracic vein with remodeling technique
2016
International audience; We report a case describing endovascular treatment of a large aneurysm of the superior vena cava involving internal thoracic vein. The goal of this case report is to highlight the contributing role of embolization with remodeling technique in such an exceptional condition.
