    Description / Table of Contents: Zusammenfassung Ein 43-jähriger Patient klagte seit 2 Wochen über zunehmende Claudicatiobeschwerden im rechten Bein. Sowohl dopplersonographisch als auch angiographisch zeigte sich ein an der Aortenbifurkation beginnender Verschluß der A. iliaca communis (AIC). Initial war eine Herzkatheteruntersuchung durchgeführt wor-¶den.¶   Über einen cross-over-Zugang von der kontralateralen Seite ließ sich der Verschluss mit einem Draht überwinden. Nach Rekanalisation mit dem Excimer-Laser wurde die ipsilaterale Seite punktiert und, zum Schutz von Aorta und A. iliaca links, in „kissing-balloon”-Technik die AIC rechts dilatiert und die Beckenstrombahn mit 3 Stents versorgt. Der Patient war anschließend beschwerdefrei, klinisch und dopplersonographisch war die Durchblutung normal und der Laufbandtest unauffällig.¶   Schlussfolgerung: Auch bei direkt am Abgang aus der Aorta verschlossenem Beckengefäß lässt sich nach lasergestützter Rekanalisation in „kissing-balloon”-Technik ohne weitere Gefährdung des Patienten eine perkutane Revaskularisierung mit gutem Ergebnis durchführen. Ein gefäßchirurgisches Vorgehen ist nicht erforderlich.
    Notes: Summary A 43-year-old patient was admitted for severe claudicatio in his right leg, doppler ultrasound and angiography revealed an occluded right common iliac artery.¶   Using the cross-over-approach from the contralateral side, it was possible to navigate a guide wire through the occlusion, and after passage with an excimer laser an ipsilateral retrograde puncture with placement of a sheath was performed. In order to protect the the aortoiliac bifurcation, a primary stent implantation of the occluded side was carried out using the kissing balloon technique. Afterwards three stents were placed. Subsequently the patient completely improved; treadmill exercise test and duplex sonography showed good results.¶   Conclusion: Using the kissing balloon technique, laser-assisted recanalisation of iliac artery occlusions even involving the aortoiliac bifurcation compare favorable to other more invasive treatments. A surgical procedure can thus be avoided.

    Notes: Abstract. The monomer evaporation energies and fission barriers of doubly charged silver cluster ions in the size range 9≤n≤25 are measured by collision induced dissociation. They are compared to the dissociation energies of singly charged silver clusters. A macroscopic liquid drop model combined with empirical microscopic corrections successfully describes the measured fission barriers.

    Notes: Abstract. Singly charged silver clusters Ag n + in the size range n=17 to n=78 have been captured and stored in a Penning trap, size selected and subjected to an electron beam which leads to further ionization as well as dissociation. The resulting abundance spectra of doubly and triply charged clusters show several features: (1) A critical size for the production of doubly charged clusters which can be understood in terms of the decay pathways as previously investigated by collision induced dissociation, (2) an odd-even alternation in the abundance of singly and doubly charged clusters which inverses sign with change of charge state, (3) prominent signals for particular doubly and triply charged species that indicate both electronic and geometric influences on the clusters’ stability.
