Case Studies
In this clinical case, an experienced surgeon initially overlooked critical flow measurement findings during CABG, leading to a decision not to revise a graft despite indications of potential complications.
This case from the REQUEST study illustrates how High-Frequency Ultrasound Imaging can be used during surgery to detect unexpected issues with the conduit to avoid complications and improve graft patency.
This case from the REQUEST study illustrates how High-Frequency Ultrasound Imaging can be used during surgery to detect intramural vessels, to avoid complications, and improve graft patency.
This case illustrates a low-flow situation of a Cimino fistula on the left forearm with a juxta-anastomotic stenosis. Transit Time Flow Measurement (TTFM) and High-frequency Ultrasound Imaging (HFUS) served as completion control.
HFUS identifies previously undetected plaque in the aorta.
A patient was readmitted on post-OP day 8 due to pain in the leg after a fem-pop in-situ bypass. This case shows how Transit Time Flow Measurement (TTFM) and High-Frequency Ultrasound was used during the reoperation.
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.
This case shows that the expectation of a huge increase in flow is not always met in every case. However, Transit Time Flow Measurement (TTFM) showing changes in the flow curve and High-Frequency Ultrasound (HFUS) can reveal otherwise undetected issues.
See 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 the outcome of the procedure.
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.
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 handle the situation appropriately.
This case demonstrates how Transit Time Flow Measurement (TTFM) and High-Frequency Ultrasound (HFUS) were instrumental in avoiding a catastrophic incident. A thrombus in the saphenous vein graft (SVG) was detected during surgery.
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 graft. These insights helped the surgeon identify the issue and address it appropriately.
This case from the REQUEST study describes how the combined use of Transit Time Flow Measurement (TTFM) and High-Frequency Ultrasound (HFUS) revealed a dissected LIMA. These insights helped the surgeon identify the issue and address it appropriately.
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.
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.
Intriguing case featured in the paper: "Epicardial Ultrasound in a Case of Myocardial Bridge and Apical Hypertrophic Cardiomyopathy" by Lindsey Whalen, Stephen Davies, Karen Singh, and Gorav Ailawadi.
This case illustrates how ultrasound imaging enables more correct detection of higher-grade defects than angiography after CEA. The case is provided by the authors of the CIDAC Study.
