Long sheath use in femoral artery catheterizations in infants <15 kg is associated with a higher thrombosis rate

Objectives To examine the factors contributing to arterial thrombosis after catheterization, particularly the use of long vs. short introducer sheaths, and propose a new protocol to address risks. Background Post-procedure arterial compromise is an important concern in pediatric cardiac catheterizations. For certain interventional procedures, the use of a long sheath is necessary, however, the incidence of complications when using such sheaths has not yet been studied. Methods This retrospective review includes patients
