Hemoglobinuria was monitored throughout the treatment course, and postoperative AKI was assessed by comparing the preoperative(baseline) and postoperative serum creatinine(sCr) levels from the electronic medical records of all patients. AKI was defined as an elevation in the sCr level exceeding 26.5 μmol/L within 72 h after the operation according to the Kidney Disease Improving Global Outcomes criteria.Results: A total of 493 consecutive patients with IFDVT were reviewed, of which 382(mean age, 56 ± 11 years;41% of them were females;97 in group A, 128 in group B, and 157 in group C) were finally analyzed. Macroscopic hemoglobinuria was evident in 44.89% of the patients of the MT groups(101/225, 39 in group A, and 62 in group B), with no significant difference between the groups(P = 0.219), but not in the patients in group C. None of the patients developed AKI(mean sCr difference-2.76 ± 13.80 μmol/L, range =-80.20 to 20.60 μmol/L) within 72h after surgery.Conclusions: Rheolytic MT is an independent risk factor for hemoglobinuria. A proper aspiration strategy, hydration, and alkalization following thrombectomy are particularly favorable for preventing AKI.展开更多
