Das pelvine venöse Kongestionssyndrom ist eine wenig bekannte, aber letztlich häufige Ursache für Unterleibsschmerzen [1] [2] [3]. Da chronische Unterleibsschmerzen unterdiagnostiziert werden, sind die Angaben zur Prävalenz mit ca. 2,1–24% der Frauen recht schwankend [2]. In 10–30% kann dabei als Ursache ein pelvines venöses Kongestionssyndrom in Betracht kommen, wobei besonders prämenopausale Frauen und Multipara betroffen sind [2]. Das Syndrom soll im Folgenden genauer beleuchtet werden. Publication Date: 03 March 2022 (online) © 2022. Thieme. All rights reserved.

Diagnosis of cerebral sinus vein thrombosis is still a challenge for imaging. MRI and MRA play a major role in sinus imaging. For further development of MR techniques, MR-compatible animal models are required. The aim of this study was to develop an animal model for sinus thrombosis and additional cortical vein thrombosis with a clot of human blood for MR imaging studies.

Causes of stroke in young adults include a variety of disorders that are less frequently seen in older patients. We report the case of a young patient, who suffered recurrent mild embolic infarctions from a free-floating thrombus formation of the internal carotid artery bulb. During preoperative preparation, the thrombus dislodged and led to middle cerebral artery occlusion and major stroke. Both during preoperative work-up and after thrombus displacement balanced fast field echo sequences were able to demonstrate thrombus with a high signal-to-noise ratio and a superior delineation of thrombus and flowing blood. The high contrast between blood and thrombus helped to establish the diagnosis, to plan subsequent treatment strategies and to follow closely the clinical course. Further studies have to show whether this technique might help in thrombus characterization.
