Knowing whether an underperforming conduit should be rejected or not is very valuable information. This case from the Request Study describes how the combined use of Transit Time Flow Measurement (TTFM) and High-Frequency […] -
Vascular Cases
This case demonstrates how Transit Time Flow Measurement (TTFM) can be used during liver transplant surgery as a guide when modulating the portal venous flow (PVF) to avoid hepatofugal flow. Hepatofugal flow […] -
Cardiac Cases
Graft patency verification can be difficult in cases with competitive flow. This case from the Request Study describes how the combined use of Transit Time Flow Measurement (TTFM) and High-Frequency Ultrasound (HFUS) […] -
Vascular Cases
This case demonstrates how High-Frequency Ultrasound (HFUS) can detect thrombus in the hepatic artery even when Transit Time Flow Measurement (TTFM) did not reveal any flow related issues. The case example consists only […] -

This case from the REQUEST Study describes how the combined use of Transit Time Flow Measurement (TTFM) and High frequency ultrasound (HFUS) revealed a compromised anastomosis, enabling the surgeon to […] -
Vascular Cases
This case shows the benefit of using Transit Time Flow Measurement (TTFM) in addition to High-Frequency Ultrasound (HFUS) after CEA when dealing with a kinked ICA. Finding kinks like these before performing CEA […] -
Cardiac Cases
This case illustrates how High-frequency Ultrasound Imaging (HFUS) can be used to identify or locate aortic dissections. Early discovery and precise location of this highly critical incident can be very significant to […] -
Vascular Cases
This case shows that the expectation of a huge increase in flow is not always met in every case. However, a significant change in the flow curve can be seen. […] -
Cardiac Cases
This case from the REQUEST Study illustrates how High-frequency Ultrasound Imaging (HFUS) can be used to identify soft, non-palpable plaque in the aorta, thus avoiding unnecessary manipulation of the affected areas. […] -
Vascular Cases
Patient medical history: Patient with PAD and Fontaine stage IV on the right side. See image 1. Initial surgery: Fem-pop bypass. The surgery went uneventfully and the TTFM showed 41 […] -
