    Description / Table of Contents: Zusammenfassung. Eine akute Blutung aus einer Pseudocyste oder einem Pseudoaneurysma ist eine gefürchtete Komplikation der chronischen Pankreatitis. Während die chirurgische Intervention nach wie vor eine hohe perioperative Letalität aufweist (16,8 %), scheint die zunehmend eingesetzte arterielle Katheterembolisation weniger riskant zu sein (6,1 %). Wir berichten über 6 Patienten mit Pseudocysten oder -aneurysmen an unserer Klinik, von denen 4 primär chirurgisch behandelt, die anderen beiden embolisiert wurden. Bei einem Patienten mußte 10 Tage nach Embolisation zusätzlich laparotomiert werden. Alle Patienten überlebten. Der Vergleich zweier Literaturperioden (von 1951 bis 1981 und von 1982 bis 1996) zeigt, wie wertvoll die arterielle Katheterembolisation zur Senkung der Letalität bei blutenden Pankreaspseudocysten und -aneurysmen ist.
    Notes: Summary. Acute hemorrhage from pseudocysts and pseudoaneurysms is a threatening complication of chronic pancreatitis. Whilst surgical intervention still has high perioperative mortality (16.8 %), transcatheter arterial embolization is becoming more frequently used for suitable cases and appears to have lower mortality (6.1 %). We report on six patients treated in our unit. Four of them underwent primary surgical treatment, the other two were treated by embolisation. One of the latter patients subsequently required laparotomy for further treatment. All six patients survived. Comparing the literature covering the periods between 1951 and 1981 and between 1982 and 1996, transcatheter embolisation seems to be valuable in controlling this type of bleeding, thereby reducing mortality.

    Notes: Preparation and Characterization of Oligomeric as well as Polymeric Ethynylsilanes Containing Si2—Si4 UnitsThe treatment of methylchlorodisilanes with ethynyldigrignard (BrMgC≡CMgBr) resulted in oligomeric as well as polymeric ethynyldisilanes. The kind of this products is related to the chloro functionality of the starting disilane. The reaction of SiClMe(SiCl2Me)2 as well as SiMe(SiCl2Me)3 yielded polymers beside small amounts of the monomeric products (HC≡C)MeSi[SiMe(C≡CH)2]2 and MeSi[SiMe(C≡CH)2]3.

    Notes: The partially diethylamino substituted phenyl-chloromono- and -disilanes Cl2Ph(NEt2)Si(2) Cl2Ph(NEt2)2Si(3), [ClPh(NEt2)Si-]2 (7) and Cl(NEt2)PhSi—SiPh(NEt2)2 (8) were synthesized. 3 and 8 are able to react with lithium powder to form the corresponding silyllithium compounds. The resulting species were characterized in solution by 13C and 29Si NMR spectroscopy. To prove the expected substitution patterns of the silyllithium compounds some coupling reactions with chlorosilanes were carried out and the resulting new oligosilanes were characterized by means of NMR spectroscopy and MS.
