Lege Artis Medicinae - 1992;2(10)

[The newest ultrasound method for the exa mination of the peripheral and abdominal vessels is Color Velocity Imaging (CVI) or time domain correlation method. In contrast to the widely accepted color Doppler imaging technique CVI is based on a different principle. Blood flow velocity is displayed using time-shift measurement ins tead of frequency-shift. This paper is brief summary of the principle of CVI method with a special emphasis on the new features. Improved special color resolution, direct velocity measurement from the color images and blood flow volume calculations are the most important new features. Authors preliminary clinical experience with this new ultrasound method is positive. A few illustrative cases demonstrate CVI and CVI-flowmetry in clinical practice. CVI is a promising new ultrasound method for imaging and quantification of human blood flow. ]

[Diagnosis and treatment of acute obstetrical DIC]

RÁKÓCZI István

[Modern management of acut obstetrical diffuse intravascular coagulation (DIC) was evaluated. A large variety of obstetrical conditions are associated with acute DIC such as amniotic fluid embolism, abruptio placentae, intrauterine infection (septic abortion), dead fetus syndrome and prolonged shock of any aetiology. Typically, acute obstetrical DIC is associated with haemorrhage (mainly vaginal bleeding) and shock. The whole blood coagulation time, platelet count and fibrinogen level are the most clinically useful indicators in evaluating the patient with acute DIC. Management of acute DIC includes prompt treatment of precipitating factors (delivery of fetus in placental abruption, evacuation of the uterus in septic abort union plus administration of antibiotics, delivery of a dead fetus by induction of labor). Careful attention to fluid and blood cell replacement is needed to prevent and treat hemorrhagic shock. The coagulation failure is treated with fresh-frozen plazma or cryoprecipitate and platelets. In acute obstetrical DIC complicated by hemorrhage heparin has no use and will only cause the bleeding to worsen. Recently several clinical studies indicate that antithrombin III concentrates are efficacious in DIC.]

[The risk of ischemic heart disease in patients with ischemic cerebrovascular disease]

HORVÁTH Sándor

[A strong association is supported between ichemic cerebrovascular and heart diseases by several studies. Death is more commonly caused by myocardial infarction than by stroke itself in patients with asymptomatic carotid stenosis, amaurosis fugax, transient ischemic attack or ischemic stroke. Signs and symptoms of ischemic cerebrovascular diseases or asymptomatic atherosclerosis of the arteries of the neck are harbinger for both myocardial and cerebrovascular infarction. Patients suffering from ischemic cerebrovascular diseases should be routinely investigated, treated and cared for coronary artery disease in order to prolong survival. ]

[Results and perspective of gene therapy in the treatment of primary immunodeficiency]

SÓFI Gyula, MARÓDI László

[During the last decade research has been directed toward gene-replacement therapy of genetic disorders, including primary immunodeficiencies. Efficient methods for gene transfer were developed to correct the gene defect in adenosine desaminase deficiency, leukocyte adhesion deficiency and chronic granulomatous disease. Somatic gene therapy in a patient with ADA deficiency was performed two years ago. This paper summaries inicial clinical applications of gene transfer and gene therapy in primary immunodeficiency and the future prospects of gene therapy in cohort of patients. ]

[Third International Study of Infarct Survival]

MATOS Lajos

[There was no significant difference in 35-day mortality between the aspirin + heparin and aspirin-only groups. The incidence of re-infarction was slightly lower with aspirin plus heparin (2p <0.09). When patients also received heparin in addition to aspirin, transfusion was needed more often and non-cerebral haemorrhage was more frequent (2p < 0.01) Combining the results of ISIS-3 and GISSI-2, mortality was significantly reduced during the treatment period (p < 0.01). There was no appreciable difference in mortality or re-infarct incidence between the use of streptokinase or APSAC, but there were more allergic events in the APSAC group. There was no difference in 6-month survival between the two groups. There was no difference in the efficacy of streptokinase and tPA treatment at either 0-35 days or 6 months survival. Allergies were less frequent with tPA, but non-cerebral haemorrhage was more frequent. Treatment with tPA led to stroke significantly more often than streptokinase (2p < 0.01). Combining the data from the similar GISSI-2 trial and ISIS-3, no difference was observed between streptokinase and tPA in either mortality between 0-35 days or survival at 6 months. ]

The applications of transcranial Doppler in ischemic stroke

FINNSDÓTTIR Herdis, SZEGEDI István, OLÁH László, CSIBA László

Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

Chronic cerebrospinal venous insufficiency - disease or misdiagnosis?

PÁNCZÉL Gyula, SZIKORA István, BERENTEI Zsolt, GUBUCZ István, MAROSFŐI Miklós, KOVÁCS Krisztina, RÓZSA Anikó, RÓZSA Csilla

Background and purpose - Former studies reported internal jugular vein stenosis in patients with multiple sclerosis. We aimed to evaluate if these venous stenoses were real and cerebral venous outflow of patients with multiple sclerosis differed from that of normal controls. Methods - 20 controls were prospectively investigated by angiography and duplex ultrasound. Seven patients with multiple sclerosis underwent angiography in other centers; we reviewed these registrations and performed venous ultrasound examinations. Results - Angiography displayed >50% stenosis of internal jugular vein in 19 controls (69±17% on the right and 73±13% on the left side) and <50% stenosis in 1 control (43.5% and 44.6%). All 7 patients had at least one-sided stenosis. The mean degree of stenosis was 63±16% on the right and 67±13% on the left side. There was no significant difference in the degree of stenosis between patients and controls. However, these “stenoses” disappeared if the contrast agent was injected at a catheter position below the orifice of the subclavian vein during venography. The venous flow volume was also similar between groups: 479.7±214.1 and 509.8±212.0 ml/min (right and left side) in the patients and 461.3±224.3 and 513.6±352.2 ml/min in the control group; p=0.85 and 0.98 (right and left). Color and power duplex imaging also revealed normal blood flow of the internal jugular vein in all patients and controls. Conclusion - The cerebral venous status of patients with multiple sclerosis and controls were similar. The angiographic “stenoses” were virtual, caused by the contrast dilution effect of the non-contrast blood stream of the subclavian vein.

[Ultrasound of the acute pediatric scrotum]

COLEY D. Brian

[Proper evaluation of the acute scrotum, like any condition, starts with a history and physical examination by an experienced clinician. Often this is all that is needed to arrive at an accurate diagnosis, which then allows prompt and appropriate treatment. However, the true nature of the underlying disease producing scrotal pain is not always clear, and the consequences of error (testicular loss) are undesirable. Ultrasound is the single most useful imaging tool for imaging the scrotum. While nuclear medicine studies can help assess blood flow, the combination of anatomic detail provided by modern ultrasound equipment and the ability to assess blood flow and perfusion with color Doppler makes ultrasound invaluable. Properly performed and interpreted, ultrasound provides very high sensitivity and specificity for acute scrotal conditions. Understanding of the conditions that produce acute scrotal pain in children will improve one’s diagnostic abilities. The most important diagnosis to consider is testicular torsion, since untreated this will result in testicular death. While testicular torsion can occur at any age, it is most common in the perinatal and peripubertal age groups. Torsion of a testicular appendage is a frequent cause of scrotal pain in prepubertal males. The sonographic findings can mimic epididymitis, but diligent and focused sonographic examination can make the diagnosis. Epididymitis typically affects postpubertal males, but can be seen in younger patients with functional or anatomic urinary tract anomalies. Sonographic evaluation of the post-traumatic painful scrotum can help to differentiate injuries that can be managed conservatively and those that require surgery. Less common causes of scrotal pain include hernias and hydroceles, vasculitis, and idiopathic edema. Understanding the characteristic sonographic features of these conditions allows the examining physician to make more accurate and confident diagnoses. It is hoped that this review article will help to promote this understanding.]

[The role of MRI in the diagnosis of tumours]

GŐDÉNY Mária

[Imaging is important in the evaluation of tumour detection, staging to determine the response to therapy, to follow the patient to find an early recurrent tumour. The ability to assess cancer spread has been revolutionized by advances of digital imaging modalities, such as digital ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). MRI is the method of choice for detecting and evaluating brain, spine, head and neck and musculoskeletal tumours, but it is complementary in the investigation of the thorax. US and CT remains the primary test for imaging the abdomen, while MRI plays a subsidiary role as a problem solving technique. In the evaluation of focal liver disease numerous prior reports have documented a superior performance of MRI compared to CT and US in the detection of primary and metastatic liver tumours. MRI is gaining more and more importance in imaging of the pelvis. Breast MRI is increasingly used as an adjunct to conventional imaging modalities. Several recent developments in MRI have altered the role of this imaging, and it is often the preferred choice among diagnostic tools for the detection and characterization of tumour cases.]

[Ethiopathogenesis of polycystic ovarian syndrome and imaging diagnostics of polycystic ovary]

JAKAB Attila, MOLNÁR Zsuzsanna, TÓTH Zoltán

[Polycystic ovarian syndrome is a heterogenous syndrome with a wide variety of endocrine and metabolic abnormalities and clinical symptoms. It is considered as the most frequent endocrine disorder in women in reproductive age and the most common cause of anovulatory infertility. Key features include menstrual cycle disturbance, hyperandrogenism and obesity. There are many extraovarian aspects to the pathophysiology of polycystic ovarian syndrome, but ovarian dysfunction is central. The underlying unique feature of the ovarian morphology gives the significance of the ultrasound examination. At a recent consensus meeting, a refined definition of the polycystic ovarian syndrome was agreed, encompassing a description of the morphology of the polycystic ovary. The subjective appearance of polycystic ovary should not be substituted for the definition. Further, a woman having polycystic ovary in the absence of menstrual disorder or hyperandrogenism (asymptomatic polycystic ovary) should not be considered as having polycystic ovarian syndrome, until more is known about the situation. Since ultrasound description of polycystic ovary morphology has central role in the diagnosis, and untreated polycystic ovarian syndrome carries long term health risks, the increasing attention to ovarian morphology may offer an effective tool to decrease women`s morbidity. This review outlines the background and feature of ovarian morphology in polycystic ovarian syndrome, and details the current ultrasound definition of polycystic ovary.]
