[Prevention of thrombotic complications in vascular interventional procedures]


[Procedures of vascular interventional radiology is linked inevitably a certain amount of risk of thrombotic complications, like intimal and vascular wall injuries, increased thrombotic risk caused by the catheter itself, etc. The first approach of thrombotic prevention was achieved by acetyl salicylic acid in case of peripheral arteries, this treatment was later replaced by long-term anticoagulation. Opportunities were provided by the recognition of risky blood characteristics in relation to thrombotic complications. Consequently, a well performed preparation and premedication of the patients could reasonably decrease the risk. The most important steps are the cessation of smoking, normalization of hemoconcentration and antithrombotic premedication. Better understanding of the nature of atherosclerotic progression led to the introduction of long-term fibrinolytic inhibition therapy. In the past decades beside patients with vascular stenosis, the oncology patients are also treated by different radiological interventions, like intraarterial chemotherapy and chemoembolization. The use of several-day-long infusion represent a new challenge, the treated vessels, the lumen and the surface of the catheter must be prevented of thrombosis. For this purpose a few suitable drugs can be applied with mild anticoagulant and fibrinolytic stimulating effect. We use the sodium pentosan polysulphate.]

[Comparison of the results of lung helical CT and lung scintigraphy in pulmonary embolism]

WENINGER Csaba, BODROGI Gabriella, BOROS Szilvia, SCHMIDT Erzsébet, UDVAROS Eszter, ZÁMBÓ Katalin

[INTRODUCTION - The frequency of the pulmonary embolism is high and the underdiagnosis or delayed recognition of the disease occurs. Recently the helical CT is used to detect pulmonary embolism. The authors compare the results of single-slice spiral thoracic CT and lung scan. PATIENTS AND METHODS - During one year period chest CT examination was performed in 49 patients due to the suspicion of pulmonary embolism, in 30 of them lung scan was also performed. RESULTS - The results of the two diagnostic methods were the same in 21 cases out 30 (in 13/21 cases both methods demonstrated embolism and 8/21 cases the findings were normal). In the remaining nine cases the findings were different. CONCLUSIONS - The lung CT examination is a rapid, non-invasive method to depict the central pulmonary embolism and small infarcts in non fresh cases. The negative result of perfusion lung scan can exclude the pulmonary embolism. If the lung scan demonstrates perfusion defect(s), it is necessary to perform another diagnostic tests (e.g. chest X-ray, ventillation scan). While the lung scan is a cheap, simple method with low radiation dose, it can play important role in the screening.]

[The possibilities of invasive radiological therapy of deep venous thrombosis and in vitro experimental examination of therapeutic factors affecting the treatment]


[INTRODUCTION - The first part of this paper is an overview on the possibilities of invasive radiology treatment of deep venous thrombosis. In the next part an in vitro experiment is described demonstrating the basics of mechanical and pharmaco-mechanical catheters applied in deep venous thrombosis. MATERIALS AND METHODS - The in vitro haemodinamic model of the iliocaval veins contained a thermostat and an engine responsable for pulsing circulation according to the venous system. We tested the chance of driftage of thrombus in different age according to the state of the collateral system. Thrombectomy was made by mechanical (Simpson-catheter) and pharmaco-mechanical (Pulsespray catheter) ways. The weight of the non-drifted thrombi was measured. RESULTS - All the 16 thrombus were flown while collateral system was closed and none of them were flown while the collateral system was open but the rate of their solubility was different. The efficacy of the thrombus-removal by Simpson catheter was better than by Pulse-spray catheter and fresh thrombus-fragments were more soluble than older ones. CONCLUSION - By this in vitro experiment we opened the way for using mechanical and pharmaco-mechanical catheters in deep venous thrombosis.]

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]


[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used pharmaceuticals. Nevertheless, a number of studies emphasized that NSAIDs were damaging not only the gastrointestinal (GI), but also the cardiovascular (CV) system, could increase the blood pressure, the frequency of coronary events (angina, myocardial infarction) and stroke incidence, as well as they might deterio­rate renal functions. The National Institute for Health and Care Excellence (NICE) did not find evidence that administering NSAIDs could increase the risk of developing COVID-19 or worsened the condition of COVID-19 patients. However, unwanted effects of specific drugs differ substantially in their occurrence and seriousness as well. It seemed to be for a long time that the NSAIDs provoked higher GI-risk was closely related to the COX1/COX2 selectivity, like the cardiovascular (CV) risk to the COX2/COX1 selectivity, however, the recent data did not prove it clearly. Based on the available literature while pondering the gastrointestinal and cardiovascular adverse events, among all NSAIDs the aceclofenac profile seemed to be the most favourable.]

[Use of the ankle-brachial index in occupational healthcare]

SZOBOTA Lívia, HIRDI Henriett Éva

[Elevated risk of fatal and non-fatal cardiovascular events is associated with high prevalence of peripheral arterial disease (PAD). Nurses working in occupational healthcare are ideally situated to identify individuals with undiagnosed PAD. The aim of the study: This study aimed to demonstrate that the ankle-brachial index (ABI) is a tool to be used by occupational health nurses in prevention of cardiovascular disease (CVD). A cross-sectional study was carried out with patients (N=638) from an occupational healthcare setting in 2021. The ABI was measured with an oscillometric blood pressure device. The measurements were analysed with the help of SPSS 22.0; descriptive statistics were calculated. A total of 638 patients were included. Mean age of the population studied was 46.5 ± 8.2 years; 38.4% were men and 61.6% were women. Mean ABI were 1.08 in right legs, 1.06 in left legs. Only 11 subjects (1.72%) had an ABI < 0.90. Occupational health nurses are able to identify key factors related to PAD, including use of the ABI, and to identify individuals with the disease. The determination of ABI using an oscillometric blood pressure device is feasible and easy to implement in occupational healthcare.]

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.

Liver transplantation is the only curative treatment in patients with end-stage liver failure. It has been associated with neurological disorders more frequently than other solid organ transplantations. We aimed to detect neurological disorders in liver transplantation patients and determine those that affect mortality. One hundred eighty-five patients, 105 with and 80 without neurological disorders, were included in this study. The follow-up was categorized into three periods: preoperative, early postoperative and late postoperative. We analyzed all medical records, including demographic, laboratory, radiological, and clinical data. Neurological disorders were observed in 52 (28.1%) patients in the preoperative period, in 45 (24.3%) in the early postoperative, and in 42 (22.7%) in the late postoperative period. Hepatic encephalopathy in the preoperative and altered mental state in the post­operative period were the most common neurological disorders. Both hepatic encephalopathy (37.5%) and altered mental state (57.7%) caused high mortality (p=0.019 and 0.001) and were determined as indepen­dent risk factors for mortality. Living donor transplantation caused less frequent mental deterioration (p=0.049). The mortality rate (53.8%) was high in patients with seizures (p=0.019). While mortality was 28.6% in Wilson’s disease patients with neurological disorders, no death was observed in patients without neurological disorders. We identified a wide variety of neurological disorders in liver transplantation patients. We also demonstrated that serious neurological disorders, including hepatic encephalopathy and seizures, are associated with high morbidity and mortality. Therefore, in order to avoid poor outcomes, hepatic encephalopathy should be considered as a prioritization criterion for liver transplantation.

[A case of destructive cervical spondylarthropathy related to chronic dialysis]

BERTA Balázs, KOMÁROMY Hedvig, SCHWARCZ Attila, KAJTÁR Béla, BÜKI András, KUNCZ Ádám

[A case of a 61-year-old male patient suffered chronic renal failure and dialysed for 23 years with destructive cervical spondylarthropathy is presented. The patient presented with sudden onset of cervical pain radiating into his shoulders without neurological deficits. CT and MRI of the cervical and thoracic spine revealed severe destructive changes and compressive fractures of C6 and C7 vertebrae which caused the narrowing of the nerve root canals at these levels. A 360-degree fixation was performed to treat the unstable fracture and the patient’s pain (C6 and C7 corpectomy, autolog bone graft replacement of the two vertebral bodies, anterior plate fixation and posterior instrumentation with screws and rods). Postoperatively the patient had no significant pain, no neurological deficit and he was able to manage independent life himself. During the immediate follow-up CT of the neck showed the satisfactory position of the bone graft and the metal implantations. The 6 months follow-up CT revealed the anterior migration of the two screws from the Th1 vertebral body and 2 mm ventral elevation of the caudal end of the plate from the anterior surface of the Th1 vertebral body. The 1-year follow-up could not be performed because the patient died due to cardio-pulmonary insufficiency. This is the second Hungarian report of a chronic dialysis related severe spondylarthropathy which may cause pathologic fractures of the vertebral bodies. The typical radiological and histological findings are discussed. This disease affect patients’ quality of life and the conservative treatment alone seems to be ineffective in most cases. Based on the literature and personal experiences, the authors suggest 360-degree fixation of the spine to provide sufficient stability for the vertebrae of ”bad bone quality”, and early mobilisation of the patient can be achieved.]
