This is a report about 4 patients with aneurysms of the superior mesenteric artery of arteriosclerotic, mycotic and probably congenital etiology together with a review of the literature as to the etiology, diagnostic possibilities and therapy. Arteriography is the method of choice even though a diagnosis may be possible by sonography or CT in special cases. Even though an aneurysm of the superior mesenteric artery is rare, it has to be considered in the differential diagnosis of persisting abdominal problems of unknown origin. This is especially true for patients with a predisposing history such as previous or existing endocarditis, sepsis, arteriosclerosis and hypertension. Because of the possibility of rupture followed by life threatening bleeding an adequate diagnostic step such as arteriography has to be considered finally.

65 newborns or low-birthweight infants with suspicion of intracranial hemorrhage were examined with B-mode small part scanners. In 12 cases the diagnosis made by ultrasound could be compared with CT. There was a similar accuracy of both methods in case of intraventricular (IVH) and subependymal (SEH) hemorrhage. SEH seems to be easier detected by US. On the other hand there are problems in diagnosing subdural (SDH) and intracerebral (IHC) hemorrhages by US. These problems are caused by the adjacent skull, but does not exist for CT. B-mode-Echoencephalography is the method of choice for examination of high risk infants and for the follow up, because US is a cribside method and of high diagnostic accuracy. CT-studies should be done in case of hemorrhage adjacent to the skull and if the US-diagnosis seems not to be reliable.

Bei transplantierten Nieren wird zur frühzeitigen Erkennung lokaler Komplikationen, wie Lymphocele, Urinom, Blutung, Infektion, und ihrer Abgrenzung gegenüber akuter Abstoßung die Sonographie eingesetzt. Im Klinikum Großhadern wurden seit Dezember 1978 alle transplantierten Nieren routinemäßig untersucht (n = 72). 22 lokale Komplikationen (3 Urinome, 4 Harnstauungen, 4 Hämatome bzw. 1 drohende Ruptur, 8 Lymphocelen, 3 Wundinfektionen wurden erkannt und rechtzeitig einer chirurgischen bzw. urologischen Therapie zugeführt. Die routinemäßige Sonographie trägt dazu bei, die Frühletalität bei Transplantatnieren zu senken.

: Routine follow-up examinations by ultrasonography after renal transplantation were performed in 72 patients from December 1978 until March 1980. The aim of these controls was to recognize local complications in the area or surgery in order to differentiate from a rejection reaction in patients with unclear clinical symptoms. 22 out of 72 patients had local complications. 15 out of those 22 were detected by ultrasound in a state without clinical symptoms, which then could be treated by surgical or urological intervention. We therefore believe that routine follow-up examinations after renal transplantation by ultrasound are indicated in order to recognize local complications. Nuclear procedures should be employed if alteration of blood flow or disturbed function of the transplanted kidney are considered.
