BACKGROUND: In a preliminary trial, we were able to show first promising results in the
analysis of perioperative and postoperative perfusion of free flaps by means of a new …

Background: Free tissue transfer in head and neck reconstructions has a very high success
rate, but thrombotic vessel occlusion is still a serious complication occurring in up to 10% of …

Free flaps are regularly used in plastic and reconstructive surgery but have a significant
failure rate due to vessel thrombosis in the re-established arterial or venous circulation. A …

Purpose: Evaluation of two complementary methods, ie luminescence ratiometric oxygen
imaging (LROI) and contrast-enhanced ultrasound (CEUS) for postoperative evaluation of …

BACKGROUND: Early identification of flap failure is an indispensable prerequisite for flap
salvage. Although many methods of free flap monitoring are available, there is still no single …

Background: Tissue oximetry is a useful tool for postoperative free flap monitoring. Reported
criterion values have been accurate; however, there are various complicated author …

Background When mobilizing free flaps, postoperative monitoring of perfusion is crucial to
detect ischemia. Continuous monitoring may be feasible by applying a combination of tissue …

Free tissue transfer is an established reconstructive technique in plastic surgery, yet it still
has an estimated 5–20% anastomotic failure rate. 1 Several ways to monitor blood perfusion …

Background The risk for vascular complications is the highest within the first 24 hours after
free flap transfer. Clinical signs of critical perfusion are often recognized with time delay …

Background: Free flap transplantation is used more and more frequently in order to cover
extensive wound defects. The basic prerequisite for successful flap salvage after flap failure …
