AbstractAbstract
[en] Formerly, percutaneous transluminal angioplasty (PTA) of arteries below the popliteal artery was rarely performed. We have treated peripheral lesions in the tibial and pedal vessels for a long time, especially in patients with diabetic angiopathy. The paper proves the early and late results of infrapopliteal angioplasty. From March 1, 1989, until February 28, 1990, 148 patients underwent 158 infrapopliteal angioplasties, out of a total of 515 PTA procedures (30.7%). The methods included balloon dilation in 148 angioplasties (66%), PAT in 43 (19%), RAT in three (1%), local fibrinolysis in 27 (12%), atherectomy in two (1%), and endovascular stent implantation in three (1%)

AbstractAbstract
[en] The new imaging method digital subtraction angiography (DSA) permits intravenous arteriography. 1259 patients were thus investigated over one year. The lower extremities comprised 21,4% of assessment areas. 120 investigations in 95 patients were based on an indication of percutaneous transluminal angioplasty (PTA). DSA can be used before and after the PTA. The small extent of invasiveness and the shortening of in-patient admission are particular advantages preoperatively. These advantages, in addition to the possibility of out-patient evaluation, are also true for DSA in comparison to the conventional arteriography. Thus the combination of both methods has been found to be very suitable. (orig.)

Die digitale Subtraktionsangiographie (DSA), ein neues bildgebendes Verfahren, ermoeglicht die intravenoese Arteriographie. Waehrend eines Jahres wurden 1259 Patienten mit diesem Verfahren untersucht. 21,4% der Untersuchungsregionen entfielen auf die unteren Extremitaeten. 120 Untersuchungen von 95 Patienten lag eine Indikation im Rahmen der perkutanen transluminalen Angioplastie (PTA) zugrunde. Die DSA kann vor und nach der PTA eingesetzt werden. Die geringe Invasivitaet und die Verkuerzung der stationaeren Verweildauer sind besondere Vorteile der PTA vor der operativen Therapie. Diese Vorteile, verbunden mit der Moeglichkeit der ambulanten Untersuchung, gelten auch fuer die DSA im Vergleich mit der konventionellen Arteriographie. Die Kombination beider Verfahren hat sich in diesem Sinne als besonders guenstig erwiesen. (orig.)Original Title

AbstractAbstract
[en] We report on the results of a comparison of intravenous and intraarterial digital subtraction angiography (iv and ia-DSA) with conventional angiography in patients with known renal masses. Whereas more than 80% of the tumours were diagnosed via IV-DSA, none of the benign renal cysts were identified. The overall detection rate, therefore, is 65% in all patients (n = 21) of the study group. The value of ia-DSA as a time sparing procedure, saving film-cost and contrastmedia, is discussed. The diagnosis accuracy of selective renal angiograms in digital and conventional technique yields equal results in our comparative study. (orig.)

Es wird ueber die Anwendung der intravenoesen (i.v.) und intraarteriellen (i.a.) DSA in der Diagnostik von renalen Raumforderungen berichtet. Mit i.v. DSA konnten ueber 80% der Nierentumoren erkannt werden, alle Zysten entgingen dem Nachweis, so dass mittels i.v. DSA 2 von 3 Raumforderungen bei 21 Patienten erkannt wurden. Der Wert der i.a. DSA wird diskutiert. Sie stellt ein zeitsparendes, kontrastmittel- und filmsparendes Verfahren dar. Vor allem bei der selektiven Renovasographie entsprechen die mit der i.a. DSA erzielten Aufnahmen denen der konventionellen Angiographie in ihrer diagnostischen Wertigkeit. (orig.)Original Title

AbstractAbstract
[en] The influence of iodine concentrations and different volumes of a conventional ionic contrast media and a contrast media with low osmolarity on the quality of the results of intraarterial digital subtraction angiography of the lower extremities in patients who underwent percutaneous transluminal angioplasty (n=52) are reported. According to our results, intra-arterial injections of a conventional ionic contrast medium diluted with 0.9% sodium chloride solution, resulting in an iodine concentration of 190 mg/ml injectable solution, reveals the best results when injected in an amount of 6 ml per injection. The use of low-osmolarity contrast-medium showed no advantages, the quality of the resulting pictures was inferior to that revealed with the ionic compound. Probably this is because the iodine concentration in the diluted low-osmolarity compound was less. (orig.)

Bei 52 Patienten nach perkutaner transluminaler Angioplastie wurde der Einfluss verschiedener Injektionsvolumina und unterschiedlicher Kontrastmittelkonzentrationen eines ionischen und eines niederosmolaren Kontrastmittels auf die Abbildungsqualitaet bei der i.a. DSA der Extremitaetengefaesse untersucht. Nach unseren Ergebnissen lassen sich mit der Injektion verduennten ionischen Kontrastmittels mit einer Jodkonzentration von mindestens 190 mg/ml Injektionsloesung und mit einem Bolus von 6 ml die besten Ergebnisse erzielen. Der Einsatz von niederosmolarem Kontrastmittel mit geringerem Jodgehalt erbringt keine Vorteile, da hier die Bildqualitaet deutlich schlechter wird. (orig.)Original Title

AbstractAbstract
[en] Rapid advances in the field of computer technology have opened the way to digital processing of the X-ray television picture both on fluoroscopy and on filming. Computerized tomography, which has revolutionized radiological diagnosis, is a prime example of the use of this new technique. With digital subtraction angiography (DSA), a further radiological procedure, likewise based on progress in the digital technique, is now becoming established. The authors' center has been operating a commercial DSA unit [DVI (Digital Vascular Imaging), a Philips system], since the middle of December 1981, and as of the date of this paper (May 1982). They have examined more than 600 patients. The following is a report on the authors present methodological concept and experience, based upon their first 400 patients
