Systemic venous collaterals and congenital portosystemic shunt: Overlooked causes of Glenn shunt failure—A case report
Year: 2026
Type: article
Study design: Case Report
Abstract: Glenn shunt dysfunction in single‑ventricle palliation is multifactorial. Although aorto‑pulmonary collaterals are usually considered, systemic veno‑venous collaterals and congenital portosystemic shunts (CPSS) may be underrecognized causes (1,7). Our patient, a 30‑month‑old child with mitral valve atresia, severe hypoplastic left ventricle, large ventricular septal defect (VSD), pulmonary valve atresia, and ductus arteriosus-dependent pulmonary blood flow, who was undergone some palliation stages including patent ductus arteriosus (PDA) stenting / modified Blalock-Taussig (BT) shunt and a right‑sided bidirectional cavopulmonary anastomosis (Glenn). Despite an initially acceptable course, the child developed progressive central cyanosis.
