WebTransplant renal artery stenosis (TRAS) is a recognised complication, occurring mostly within 3 months to 2 years, but potentially anytime post renal transplantation. TRAS … Web11 de jun. de 2024 · Doppler ultrasound (US) is a well-established and useful technique for evaluating the renovascular system and associated pathologic conditions. As with other US examinations, advantages include its noninvasive nature, relatively low-costs, and generally well-tolerated. However, the technique is highly operator-dependent and can be time …
WebPurpose: This study aims to determine a velocity threshold in the main renal vein (MRV) of renal transplants and evaluate the cause and clinical significance of elevated velocity. Methods: Maximum MRV velocity from 331 consecutive renal transplant Doppler ultrasounds in 170 patients was recorded. A priori, twice the median MRV velocity was … WebThe present community-based prospective study clearly demonstrated that arterial stiffness is a moderate and independent predictive factor for MACEs in individuals with mildly impaired renal function (eGFR <90 mL/min/1.73 m 2 ). Furthermore, in individuals with normal renal function (eGFR ≥90 mL/min/1.73 m 2 ), the risk of MACEs does not ...
