[The color Doppler method is very useful for examining the arteriovenosus fistules, the patency of anastomoses, the diagnosis and follow-up of the stenoses and for the evaluation of the lesions developed around the anastomoses. Using an Acuson 128 color Doppler ultrasound equipment, the authors have examined the subcutan arterio venosus shunts of 50 patients treated with chronic haemodialysis. 46 patients had Cimino fistulas on the lower arm, 2 had on the forearm, while two patients had graft on the forearm. In each cases the artery, the anastomosis, the vein of the shunt and the site of the punction were examined. The authors have found normal, well functioning anastomoses in 11 cases, while 29 dilatations, 8 stenoses, 2 occlusions, 1 infection, 5 haematomas and in one case dilated collateral vessels were diagnosed. The authors consider the color Doppler sonographic technique reliable for examining the function of the anastomosis, the morphologic changes, stenoses, dilatations, and the lesions developed around the shunts. The color Doppler examination is a non-invasive alternative diagnostic method opposed to angiography, which is more troblesome for these patients. ]

[Laparoscopic surgery]

ANTAL András, BÁTFAI László, EZER Péter

[In the recent years abdominal surgery has developed quickly. Laparoscopic operating procedures have spread worldwide. These techniques have reached Hungary as well, though there are only few articles in this topic. Since last December - date of the first laparoscopic cholecystectomy – more than 200 operations have been done, among them the first appendectomy. These procedures are less troublesome for the patients with better cosmetic results, and the shorter period of hospitalisation and unability for work make economical advantages. First, the technical instruments and their usage, then personal coditions and the preparation programme are described. In the second part the usage of the new technique is summarized in cholecystectomy as well as in appendectomy. ]

[Quo vadis chirurgia biliaris?]

SÁNDOR József, IHÁSZ Mihály

[Mankind has suffered from the agony of gallstones for thousands of years. Until the second half of the last century, there was practically no cure, the only relief being spontaneous internal and external fistulas in the midst of great pain.]

[Renal cell carcinoma in a horseshoe kidney treated with radical nephrectomy]

SZENTGYÖRGYI Ervin, KONDÁS József, KONDÉR Gyula

[A horseshoe kidney is diagnosed usually after the onset of its complication or the symptoms caused by an arising tumor from it. A tumour was diagnosed in the right half of the horseshoe kidney in a 68 year old female patient by excretory urography, ultrasound examination and renovasography. The tumour was removed by radical nephrectomy. The kidney was exposed through a horizontal abdominal approach. Special attention was given to the separate renal arteries supplying the right half of the horseshoe kidney and to the resection of the isthmus and also regional lymphadenectomy. In the diagnosis of a horseshoe kidney excretion urography had exclusively been used earlier but nowadays ultrasound is playing an increasingly important role. Reno vasography is usually needed only before resection or nephrectomy. The appropriate treatment of a horseshoe kidney tumour - in case of a well functioning contralateral kidney - is radical ablastic tumour nephrectomy including regional lymphadenectomy. ]

[Initial experiences with upper limb MR-angiography]

PAVLIKOVICS Gábor, KISS Máté, ENGLONER László, LOMBAY Béla

[INTRODUCTION - Cimino fistula is created for chronic hemodialysis. As a common complication steal syndrome may occur. Till recently, color Doppler and catheter angiography were the gold-standard diagnostic tools. We have performed MR-angiography of the upper limb to replace the more invasive conventional angiography in patients with poor general condition. PATIENT AND METHODS - A case of a 64 years old female patient with known type II diabetes is presented. Due to azotemia, the patient has received hemodialysis for 24 months, via a left upper limb fistula. This fistula occluded, and the Cimino-fistula was later created on the right arm. This new fistula demonstrated steal syndrome, and required formal ligation. In the meantime a necrotising drygangrene of the 4th and 5th digits was recognised. This required an emergent conventional angiography, but due to the unavailability of accessible artery, MR-angiography was performed. 1.0 mmol/ml concentration gadobutrol (Gadovist 1.0, BayerSchering, Berlin) was used to reduce the chances of nephrogenic systemic fibrosis in this patient with poor renal function. CONCLUSION - Correctly performed MR-angiography to examine the possibility of steal syndrome in patients with a Cimino fistula can be a feasible alternative. The advantages of the procedure include its minimal invasiveness, no ionizing radiation and the risk of iodine-based contrast material nephrotoxicity. Also, as compared to digital substraction angiography, with MR-angiography we obtain a high-resolution, isotrope voxel-sized 3D acquisition which can be better read in many different planes. As a drawback, currently on-location intervention cannot be performed, if needed. Also, the waiting periods may be long.]

[A new ultrasound method for the examination of the circulation: color velocity imaging (CVI)]

HARKÁNYI Zoltán, DANIEL Morton, JI-BIN Liu, BARRY B. Goldberg

[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. ]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]
