Femoral Artery Thrombosis After Pediatric Cardiac Catheterization


Femoral artery thrombosis (FAT) is an adverse event post-catheterization. We decided to study the incidence and risk factors of FAT before and after initiation of a pulse loss monitoring program. All cardiac catheterization cases performed using femoral arterial vascular access were retrospectively reviewed. The study period was divided into two eras: before (era 1), and after the initiation of the protocol (era 2). The primary outcome was FAT requiring therapy. Univariable and multivariable logistic regression models were used to identify factors associated with FAT. Receiver operating characteristic curve were generated to predict FAT. Our cohort consisted of 2,388 cases including 467 (19.6%) infants weighing < 10 kg. The overall incidence of FAT was 1.7% (n = 41). The incidence of FAT was 3.5 times higher in era 2 (p < 0.001). Multivariable model showed that era, weight, sheath exchange, and coarctation intervention were significantly associated with FAT. Infants younger than 7.7 months and less than 6.7 kg were found to be at highest risk for FAT. Our study shows that the incidence of FAT may be underestimated without a monitoring program. Small infants and coarctation interventions requiring larger sheaths or sheath exchanges are at highest risk for FAT.
