WebFeb 24, 2024 · Duplex Doppler ultrasound (US) is the principal imaging modality used to assess the renal allograft in both the immediate postoperative period and for long-term follow-up. Advantages of US include the ability to detect complications without the use of iodinated or gadolinium-based contrast agents, low cost, and lack of ionizing radiation. Webtardus parvus.

WebDec 1, 1993 · Doppler parameters measured in the distal renal artery included systolic acceleration, acceleration time, peak systolic velocity, deceleration in late systole, pulsatility and resistivity indexes, and waveform features in early systole. RESULTS: Angiograms demonstrated 28 stenotic renal arteries. WebBackground: Parvus-tardus waveforms of the hepatic artery after liver transplantation usually indicate an arterial complication and severe impairment of hepatic arterial perfusion with a sensitivity of 91% and a specificity of 99.1%. Thus, it has been emphasized that detection of such waveforms should prompt emergency angiography
