[Diagnosis of pelvic injuries]

NÉMETH Katalin

[In most cases, the cause of the pelvic injuries are traffic accidents and falling from heights. In the seriously injuried patients the bottomline of the treatment is to establish the accurate diagnosis. The role of X-ray technicians to should be emphasized. This paper briefly summarizes the anatomical and pathological basics of the pelvic injuries, the different the types of injuries and the examination methods of choice. Beside conventional X-ray studies, CT and portable ultrasonography are also important methods with special regard in the detection of the complications associated with pelvic injuries.]

[Omental infarction diagnosed with ultrasonography]

VÁRKONYI Ildikó, VÖRÖS Péter, SZÉKELY Eszter

[INTRODUCTION - Omental infarction is a rare entity, mimicking symptoms of acute appendicitis. Although omental infarction has typical morphology, both on sonography and CT, it is rarely diagnosed preoperatively. CASE REPORT - A 4-years-old girl presenting with right lower quadrant abdominal pain underwent abdominal sonography, which revealed normal appendix and a superficial hyperechoic solid mass at the site of the pain. The patient underwent laparotomy which confirmed the presumed diagnosis of partial omental necrosis. The necrotic tissue was resected, the appendix was normal. After uneventful postoperative course the child became symptom -free and was discharged. CONCLUSION - The sonomorphology of omental infarction is typical. The suspicion of this entity should be considered as a differential diagnosis of appendicitis, especially if normal appendix can be visualized.]

[Necrotizing enterocolitis in neonatology: comparing the role of X-ray and ultrasonographic examinations]

JENEI Mónika, VÁRKONYI Ildikó, NYITRAI Anna, SZABÓ Miklós, BOKODI Géza, KIS Éva

[INTRODUCTION - The authors’ purpose was to analyse the role of abdominal ultrasonography (US) in the diagnosis of necrotizing enterocolitis (NEC). They have compared the sensitivity of the current standard diagnostic modalities for this clinical entity: plain abdominal radiography and abdominal US. For a more objective comparison, they created an US scale along with utilising the score system based on abdominal radiography which was published recently. PATIENTS AND METHODS - 46 out of 76 neonates having both clinical and radiological diagnosis of NEC had comparable radiographic and sonographic examinations between June 2006 and October 2009. The authors created a 10-grade US score system, in which sonographic signs of NEC are listed in order of severity, corresponding, where possible with the radiographic scale that was available. The findings were scored individually, then the distribution of scores and their relationship to each other were analysed. For further analysis four groups of severity based on the scores were created with the following categories: mild, moderate, severe and very severe. After graphical representation of the groups, the relationship of the groups created on the basis of scoring the findings by the two diagnostic methods were examined. RESULTS - According to this analysis both abdominal radiographs and sonographs are suitable for diagnosing NEC, which has been justified with statistical data. When analysing the severity groups the authors proved that the two methods diverge in judging groups 3 and 4, thus severe and very severe. The distributions of severity groups formed by the two imaging modalities are different, (P<0,01); and the proportion of group 3 and group 4 is different in case of US and radiographic examinations (P=0.003). CONCLUSIONS - Abdominal sonography and radiography are equally suitable diagnostic methods for diagnosing NEC, and the two methods match each other very well. In cases of mild state, the severity of the disease was found to be the same with both methods, but US allows more sensitive differentiation of serious cases. It is very sensitive in detecting perforations, so it could play a role in determining the indication of surgery.]

[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.]

[Use of covered stents in the endovascular treatment of extracranial stenosis of the internal carotid artery]

SZÓLICS Alex, VÖRÖS Erika, SZTRIHA László, SZIKRA Péter, SZÓLICS Miklós, PALKÓ András

[INTRODUCTION - Significant stenosis of the internal carotid artery is frequently treated with stent placement. With growing clinical experience and usage of finer instrumentation, the incidence of periprocedural complications have reduced in larger centers. Two-thirds of the complications are postprocedural, due to the embolisation through the stent structure. Covered stents seem to be a good option against such embolisation. Our study demonstrates the efficiency, safety and feasibility of covered stent grafts, and the long term outcome of patients who underwent endovascular treatment of extracranial internal carotid artery stenoses, caused by highly embologenic plaques. MATERIALS AND METHODS - Between 2002 and 2003, 30 patients (22 male, 8 female, aged 50-89yrs, mean: 66 yrs) with 30 internal carotid artery stenoses having ipsilateral symptoms and/or stenotic lesions caused by irregular or ulcerated soft plaques or restenosis were treated with self-expanding covered stents (Symbiot, Boston Scientific). Predilatation and protecting devices were not used. Postdilatation was applied in every patient. Mean followup was 60 months (range 57-66 months), by Doppler ultrasonography as well as clinical examination. RESULTS - The degree of stenosis was found to range from 70% to subtotal occlusion. The plaque surfaces were irregular or ulcerated in 70%. The stenotic lesions were up to 30 mm in length. The narrowing of the internal carotid artery never extended to the common carotid artery. The technical success rate of stenting was 100%. The stents could be positioned with an accuracy of 2-3 mm. Periprocedurally, there were no neurological complications or deaths. During follow-up no strokes or stroke-related deaths occurred. Restenosis was found in two patients (6,6%) who underwent successful balloon dilatation. CONCLUSION - Our experience indicates that the covered stent is an efficient periprocedural and postprocedural “protecting device” to prevent neurological complications due to embolizations caused by high-risk plaques in stenotic lesions of extracranial internal carotid artery.]
