Zusammenfassung
Die intraoperative farbkodierte Duplex-Sonografie kann bei der Klärung vaskulärer Komplikationen während Nierentransplantation hilfreich sein. Klinisch vermutete Perfusionsstörungen können durch eine Malposition des Transplantats oder durch Kompression von außen verursacht sein. Weitere Komplikationen wie intravasale Thromben, Dissektionen und Vasospasmus lassen sich gut differenzieren und lokalisieren. Die wichtigsten intraoperativen Befunde werden in dem folgenden Beitrag dargestellt und erläutert. Die farbkodierte Duplex-Sonografie ist im Rahmen von Nierentransplantationen in Einzelfällen bereits schon intraoperativ ein wichtiges Instrument zur Erkennung der Ursache von Perfusionsstörungen.
Abstract
The purpose of this pictorial essay is to describe the role of intraoperative color duplex ultrasound in detecting vascular complications during renal transplantation. Intraoperative color duplex scanning during renal transplantation detects vascular complications noninvasively. Reasons for disturbed perfusion can be malposition or external compression, intravascular thrombi, vessel wall dissection and vasospasm. Color duplex ultrasound is a useful procedure in selected conditions with an intraoperatively suspected perfusion problem during renal transplantation.
