Kawashima Operation Survival Index Calculator
- Kawashima Operation Survival Index: Explanation and Clinical Context
The Kawashima Operation Survival Index is a risk prediction tool used to estimate long-term survival probability for patients undergoing the Kawashima procedure, typically for patients with single ventricle physiology and interrupted inferior vena cava with azygos continuation.
It incorporates key clinical variables including age at surgery, preoperative oxygen saturation, presence of pulmonary arteriovenous malformations (PAVMs), and prior Glenn or shunt procedures.
Higher age and presence of PAVMs are associated with reduced survival, while higher preoperative oxygen saturation and previous Glenn/shunt procedures may modestly increase survival probability.
This tool helps clinicians with perioperative counseling, risk stratification, and long-term follow-up planning.
