| アブストラクト | Cholesterol crystal embolization (CCE) is a rare, mainly iatrogenic condition. The proportion of CCE after cardiovascular procedures has not been fully elucidated. The purpose of this study was to determine the proportion of CCE diagnosed after cardiovascular procedures and to identify risk factors for CCE occurrence. Data on patients aged older than 40 years who underwent cardiovascular procedures between July 2010 and March 2017 were extracted from the Japanese Diagnosis Procedure Combination database. Inpatients diagnosed with CCE within 1 year after procedures in the same hospital were identified. Logistic regression analysis was performed to identify factors associated with the occurrence of CCE. There were 962 patients with CCE in 2,190,300 patients who underwent cardiovascular procedures. The overall proportion of CCE after cardiovascular procedures was 4.4 per 10,000 patients (95% confidence interval 4.1-4.7). The overall in-hospital mortality among patients with CCE was 11% (107/962). Older age, male sex, smoking, heart failure, peripheral vascular disease, cerebrovascular disease, renal insufficiency, diabetes mellitus, hypertension, and aortic aneurism and dissection were significantly associated with the higher occurrence of CCE. Compared with cardioangiography, several procedures were significantly associated with higher occurrence of CCE, including intra-aortic balloon pumping, percutaneous transluminal angioplasty of the renal artery, and transcatheter aortic valve implantation or balloon aortic valvuloplasty. CCE is rare but remains a severe complication of cardiovascular procedures. Atherosclerotic risk factors and certain cardiovascular procedures were associated with CCE. |
