Abstract
【Background】Angiographic examination is often performed in patients on hemodialysis as they have a high risk for cardiovascular diseases. However, it is still unclear when the first hemodialysis session should be performed after angiography. 【Methods】We conducted a retrospective review of 323 consecutive hospitalized patients on hemodialysis (age 68±8 years, male 73%) who had undergone angiography at our hospital from April 2010 to November 2012. Hemodialysis complications were defined as symptomatic hypotension, bleeding, and dialysis interruption due to pain. All complications were extracted from the medical records. Factors associated with complications were examined. 【Results】Dialysis complications after angiography were observed in 79/323 patients (24.4%). Among them, symptomatic hypotension was the most common complication. In terms of the timing of hemodialysis, patients dialyzed on the day of angiography had a higher risk for complications than those dialyzed the day after (odds ratio 3.24, 95%CI 1.11-9.42, p=0.02). Multivariate analysis showed that hemodialysis on the same day as angiography and use of a large amount of contrast medium were significantly related to the complications. No clinical complications related to residual contrast agent were observed. 【Conclusions】Dialysis complications after angiography were often observed during the first hemodialysis session, especially performed on the same day as angiography. Therefore, first hemodialysis could be safely performed on the day after angiography.
