Restriction of congenital portosystemic shunt using the modified microvascular plug.
2021
Congenital portosystemic shunts (CPSS) may produce a variety of severe, clinically detrimental presentations. When indicated, closure is recommended; however, if the intrahepatic portal venous system (IPVS) is underdeveloped complete closure may not be possible and may result in severe acute portal hypertension. Staged restriction of CPSS flow by both surgical and complex transcatheter interventions has been successful in augmenting development of the IPVS such that complete occlusion of the CPSS can be performed. We report use of a modified microvascular plug to restrict CPSS flow with subsequent IPVS development and safe complete occlusion of CPSS.
