Low-molecular-weight dextran for optical coherence tomography may not be protective against kidney injury in patients with renal insufficiency
Background: Low-molecular-weight dextran (LMWD) is considered a safe alternative to contrast media for blood displacement during optical coherence tomography (OCT) imaging. Aim: To investigate whether the use of LMWD for OCT is protective against kidney injury in patients with advanced renal insufficiency. Methods: In this retrospective cohort study, we identified 421 patients with advanced renal insufficiency (estimated glomerular filtration rate < 45 mL/min/1.73 m 2 ) who underwent coronary angiography or percutaneous coronary intervention; 79 patients who used additional LMWD for OCT imaging (LMWD group) and 342 patients who used contrast medium exclusively (control group). We evaluated the differences ...
