Key result
Transcatheter rediversion of the inferior vena cava to the right atrium using a covered stent was successfully implemented to treat iatrogenic cyanosis caused by surgical patch misplacement.
Why the study?
Iatrogenic diversion of the inferior vena cava to the left atrium causing cyanosis after atrial septal defect repair has previously been dealt with surgically.
Case Report
Transcatheter rediversion using a covered stent provides a novel, less invasive alternative to surgical reintervention for correcting iatrogenic IVC-to-LA rerouting after ASD repair.
May offer minimally invasive correction for rare post-ASD cyanosis; hypothesis-generating and requires prospective validation before practice change.
Improper identification of the atrial septal defect margins during surgery and inadvertent suturing of the surgical patch to the Eustachian valve of the inferior vena cava (IVC) results in the diversion of inferior venacaval blood to the left atrium causing cyanosis. This complication has been dealt so far with surgery. We report the planning and implementation of a novel transcatheter rediversion of the IVC to the right atrium using a covered stent.

Sagar et al. (2023) conducted a case report in Iatrogenic cyanosis due to surgical rerouting of inferior vena cava to the left atrium. Transcatheter rediversion of the inferior vena cava to the right atrium using a covered stent was evaluated. Transcatheter rediversion of the inferior vena cava to the right atrium using a covered stent was successfully implemented to treat iatrogenic cyanosis caused by surgical patch misplacement.
