interstage period
Time interval between staged surgical procedures in single ventricle palliation sequence.
Full Definition
The interstage period refers to the critical time between stage 1 and stage 2 procedures in single ventricle palliation, typically lasting 4-6 months. During this period, patients are monitored closely for adequate growth, stable hemodynamics, and optimal pulmonary vascular development before proceeding to the next surgical stage. Home monitoring programs have been developed to reduce interstage mortality, which historically represented a significant risk period in single ventricle management.
Usage
Usage note: Specify which interstage when editing multi-stage procedures (e.g., 'stage 1-2 interstage period').
