[What may hurt the patient’s leg? Lower extremity ischaemia]

FENDRIK Krisztina, BIRÓ Katalin, KOLTAI Katalin, ENDREI Dóra, TÓTH Kálmán, KÉSMÁRKY Gábor

[Peripheral artery disease (PAD) is of high prevalence, and one of the most common clinical manifestations of the atherosclerosis beside ischaemic heart disease and cerebrovascular disease. PAD should be considered as a systemic disease, PAD patients have two times higher ten-year cardiovascular mortality than the normal population. For these reasons, the early recognition of the disease, the appropriate secondary preventive medical and non-medical therapy are of great importance. Risk stratification, proper physical examination, ankle pressure, ankle-brachial index, toe pressure, transcutaneous partial tissue oxygen pressure measurement and duplex ultrasound are the cornerstones to an early diagnosis. This summary aims at calling attention to the fact that lower extremity pain can not only be caused by musculo­sceletal diseases but limb and/or life-threatening limb ischaemia can be revealed in the background. ]

Introduction - Population-based screening is an option to identify persons at high risk for stroke. However it is associated with rather high expenses, necessitating the selection of effective methods that take local characteristics into account. The 12th district of Budapest has a long tradition of population-based screening for frequent and preventable diseases. The Szent János Hospital hosts an annual stroke screening day. In the present study, previously published data from the 2011 screening were compared with those obtained in 2016, looking for changes and tendencies throughout the examined period. Subjects and methods - The screening day was conducted in a generally similar way in 2011 and 2016. Similarly to the previous event, the program was organized on a Saturday, the call for the event was spread by the local newspaper. The crew composition was the same. As regards the components of the screening (currently including general history taking, risk status assessment, blood pressure measurement, BMI assessment, cholesterol and blood glucose tests, carotid duplex ultrasonography, and ophthalmological examination), the only difference was the absence of cardiologic examination (it was conducted on an independent day). The anonymous data sheet was the same. Results - The number of participants in the 2016 event was 33, to provide more comfortable conditions. The female predominance was slightly less pronounced but was still present in 2016 (60.6% vs. 72.9%). The mean age became substantially higher (71.2 y vs. 62.9 y). The ratios of participants with higher level of education (97% vs. 94%) and those who are married were still remarkable. The most frequent risk factors were the same; however the ratio of participants with hypertension, ‘other heart disease’, and diabetes increased, whereas that of with hyperlipidemia and obesity decreased. The incidence of atrial fibrillation was unaltered. None of the participants in 2016 admitted smoking (previously this ratio was 20.8%) or drinking heavily. The findings of the carotid ultrasonography revealed a more favorable vascular status. Ophthalmological assessments (predominantly hypertensive alterations on fundoscopy) revealed that the pathological vs. physiological ratio switched to 1:2 from 2:1. The final evaluation of the screening program likewise demonstrated an improved overall state of health of the population. Conclusions - We observed a more favorable stroke risk status of the population in 2016. Whether it is indeed a tendency unknown at present. The role of the local media in calling for screening is still decisive, and the cohesive power of the family is important.

[Renovascular hypertension is a well-known form of secunder hypertension. Two thirds of cases are caused by atherosclerotic plaque and one third are caused by fibromuscular dysplasia. The prevalence of it is less than 1%. Digital subtraction angiography is considered the goldstandard diagnostic method. The 58-year old female patient was hospitalized with resistant hypertension. Duplex ultrasonography showed fibromuscular stenosis the in left renal artery. Percutaneous transluminal angioplasty and stenting were performed. Her blood pressure normalized. The patient did not attend the control examinations. Next time in 2001, she was referred to our emergency department with increased blood pressure of 210/140 mmHg. Following control ultrasonography angiography showed total occlusion of the left renal artery and significant stenosis of the right renal artery. Left nephrectomy was necessary due to shrunken kidney and dilatation and stenting of the right renal artery. The blood pressure normalized again. Since 2004 until 2014 despite of the regular visits, we detected in stent restenosis of the right renal artery almost in each year. Even so, renal function was preserved all the time. In autumn of 2014, the patient suffered severe stroke, and few months later at the age of 74 she died. There are many open questions to discus concerning the right treatment of renovascular hypertension yet. Even so by performing 12 intravascular interventions we could ensure her acceptable quality of life for 16 years.]

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.

[Stroke prevention - A population screening day in district XII of Budapest]

FOLYOVICH András, BAKOS Mária, KÁNTOR Zita, HERTELENDY Anna, HORVÁTH Eszter, ZSIGA Katalin, LAKATOS Henriette, VADASDI Károly

[Along with advances in the treatment of acute stroke, new efforts have been made to enhance efficiency of the prevention of cerebrovascular diseases. Population screening is a way to contact high-risk patients, and there is an increasing international and national experience with the procedure. However, efforts are associated with high costs, so an efficient method, complying with local features, should be selected from the various methods. A stroke prevention day was organized in Szent János Hospital, localized in district XII, and data were analyzed. Taking advantage of the potentials of a large hospital, a comprehensive risk assessment - within the capacity of health care workers - was performed. Program and contact information of the screening day was published in the local newspaper of the district. Data of 48 residents of the district were analyzed. In addition to neurologists, a radiologist, a cardiologist and an ophtalmologist, as well as health care workers were involved in the project. A data sheet was filled in for all participants, including known risk factors, BMI, blood pressure and serum cholesterol levels. All participants had duplex sonography of the cervical vessels, cardiac evaluation and ophtalmic examination. Data were analyzed anonymously, and - if participants approved - postcode and educational level were also recorded. Among the 48 individuals screened, 35 were female and 13 were male. Average age was 62.86 (±8.57) years, and participants were typically of higher educational level. 5 individuals had no known risk factors, most of them had 2-3 risk factors, and multiple risk factors were not uncommon. Individuals with six and seven risk factors were also found. 20 of 27 patients with known hypertension had target blood pressure levels. By duplex sonography, 36 individuals had mild, 4 had significant atherosclerosis. There was no significant carotid stenosis or occlusion. Based on ophtalmic evaluation, 26 patients had signs of vascular disease (mainly hypertensive fundus changes). Cardiac evaluation detected 14 patients with cardiovascular risk. The high standard of primary care in the district was reflected by the fact that all the 6 highrisk individuals were already taken care of by general practitioners (GP-s). One of the leading conclusions from the evaluation of the data is that local press, family ties and local communities play a major role in recruiting people for a screening day. In order to increase efficiency and cost-efficacy of the program, GP-s should also be involved in the planning process, because efficiency may be increased by pre-selecting high-risk individuals.]

[Initial experiences with TOF MR and contrastenhanced MR angiography of the supraaortic arteries]

TASNÁDI Tünde, KARDOS Klára

[INTRODUCTION - 95 MR angiographic examinations of the supraortic arteries were performed at the Rethy Pal Hospital, Bekescsaba between February 2003 and May 2005. The aim of this publication is to analyse the clinical benefit of contrast-enhanced MR angiography compared to duplex ultrasound and to evaluate the role of TOF MR angiography in the diagnostics of the carotid arteries. We compared the results of contrast-enhanced MR angiography, TOF MR angiography and duplex ultrasound. MATERIAL AND METHOD - 95 patients were examined by CE MR angiography following carotid duplex US in 59 cases and TOF MR angiography in 88 cases. Duplex US was done using LOGIQ 400 PRO system, MR angiography were performed by 1.5 T Siemens Magnetom Symphony unit. RESULTS - Stenosis of the internal carotid artery was confirmed in 67 cases and stenosis of the common carotid artery was seen in 10 cases. Bilateral ICA stenoses were detected in 17 patients and bilateral CCA stenoses could be revealed in 3 cases. The ICA stenosis was mild in 22 (33%), moderate in 18 (27%), and serious in 27 cases (40%). Occlusion was seen in 10 cases (15%). CE MR angiography showed stenosis at the origin of the CCA in 5 patients, at the origin of the vertebral and the subclavian artery in 10-10 cases that could not be detected by duplex ultrasound. Subclavian artery stenosis was seen in 15 patients, 7 of them presented subclavian steal syndrome. 13 patients had vertebral artery stenosis, 7 of them bilateral. 13 of the 20 VA stenoses were mild, 4 were found to be moderate and 3 were serious. In four patients the vertebral arteries were occluded. In six questionable cases MR angiography solved the problem. Reversed flow could be detected in 5 cases with duplex ultrasound suggestive of subclavian steal syndrome, which was later confirmed by TOF and CE MR angiography. TOF MR angiography showed stenosis on reconstructed images, which was not confirmed by neither duplex US or CE MR angiography. Paraganglioma was detected in one patient. CONCLUSION - In case of calcified plaques and abnormal arterial-course CE MR angiography contributes significantly to the detection of the stenosis. In cases with moderate and serious stenosis duplex ultrasound and MR angiography provided similar results. In case of occlusions the results of the two modalities were the same. The contrast-enhanced MR angiography gives the possibility to show the aortic origin of the supraaortic arteries in contrast to the duplex US and TOF MR angiography. To establish the diagnosis of subclavian steal syndrome the directional sensitivity of TOF MR angiography and duplex US is helpful adjunct to CE MR angiography.]

[LARGE VESSEL MANIFESTATION OF GIANTCELL ARTERITIS]

KOLOSSVÁRY Endre, PINTÉR Hajnalka, ERÉNYI Éva, KOLLÁR Attila, FARKAS Katalin, KISS István, HARCOS Péter, SIMON Károly

[The diagnosis of giant-cell arteritis is a real challenge for clinicians. There are several reasons for the difficulties in establishing the diagnosis. This disease is associated to rare conditions, therefore most physicians lack clinical experience. This condition shows very heterogeneous manifestation, the intensity of the symptoms vary in time. Early diagnosis is of great importance in order to prevent ischemic complications. Among these complications one should emphasise the role of anterior ischemic optic neuropathy that may result in abrupt blindness. In this case report, we show a rare socalled large vessel manifestation of giant-cell arteritis. This form of the disease needs different approach in diagnosis where color duplex ultrasonography may have distinguished importance. The final verification of the diagnosis is based on histology. However the lack of all histological criteria do not exclude the presence of giant-cell arteritis.]

[Treatment of ureter stenosis of the transplanted kidney using invasive radiological methods]

DOROS Attila, WESZELITS Viola, PUHL Mária, RUSZ András, JANSEN Judit

[INTRODUCTION - Stenosis, occlusion and necrosis of the ureter after kidney transplantation occur in 2-13%. The therapeutic choices are surgery or minimally invasive endourological and percutaneous procedures. We analysed our therapeutic plan and results using percutaneous dilatation and stenting. PATIENTS AND METHODS - The patients after kidney transplantation are regularly examined by ultrasound. In cases of suspected obstruction we perform scintigraphy and CT-urography, and if indicated, we place percutaneous nephrostomy. Between July of 2000 and September of 2002, 15 stenosis in 14 patients were dilated and stented percutaneously. RESULTS - We found one restenosis after 6 months due to compression. This patient underwent surgery, but after the operation another stenosis has developed. We treated it percutaneously. One nephrectomy had to be performed due to serious infection. In one patient stent migration occured and surgical intervention was performed. 12 patients have free urine passage and good kidney function as a result of percutaneous therapy. CONCLUSION - We have good results with percutaneous ureter dilatation and stenting, but our follow-up time (31 months) must be longer for the evaluation of long-term results. The percutaneous treatment can partly replace endourological and surgical methods or can be combined with each other.]

[Difficulties in the diagnosis of ectopic ureter]

KONCZ Júlia, RÉTI Gyula, NYÁRI Edit, SHAIKH M. Shoaib

[INTRODUCTION - Ureter ectopy refers to the distal opening of the ureter at the site of the bladder neck or lower. 70-80% of the ectopic ureters are associated with pyelectasia and duplicated ureters. The incidence of this is 2-3 times higher in females. CASE REPORT - Following is a case report of a boy who was diagnosed with left-sided pyelectasia during a prenatal ultrasound scan. The postnatal ultrasound revealed a duplicated pelviceal cavity and ureter. The upper pole ureter and the pelvis demonstrated dilatation. At 8 months of age a left side heminehprectomy was performed. Two years postoperatively a follow-up ultrasound revealed a dilatation of the ureteral stump on the left side, which progressed. On MCUG the ureteral stump was identified inserting on to the proximal urethra. Cystography and MR urography demonstrated a ureteral stump which inserted on to the urethra. A repeat surgery was performed to remove the stump. Patient is symptom-free ever since. CONCLUSION - In ectopic, non-refluxing ureters long-term follow-up is necessary following heminephrectomy. A ureter stump besides the bladder can cause serious diagnostical difficulties. Also, it is possible that a dilating stump may lead to a reflux not identified earlier. MCUG and MR urography can help to clear delineate the pathology.]
