Intrahepatic Congenital Portosystemic Shunts

Area of Science:

• Hepatology
• Vascular Surgery
• Pediatric Gastroenterology

Background:

• Single congenital portosystemic shunts (PSS) are associated with failure to thrive and hepatic encephalopathy.
• While medical management can alleviate symptoms, surgical intervention is key for long-term improvement.
• Intrahepatic PSSs present distinct clinical and therapeutic challenges compared to extrahepatic shunts.

Purpose of the Study:

• To review the outcomes of minimally invasive intravascular approaches for treating intrahepatic portosystemic shunts (IHPSSs).
• To highlight the efficacy of percutaneous transvenous coil embolization in managing IHPSSs.
• To assess the impact of shunt attenuation on liver function and patient well-being.

Main Methods:

• Review of minimally invasive intravascular techniques for IHPSS treatment.
• Focus on percutaneous transvenous coil embolization as a primary therapeutic modality.
• Analysis of patient outcomes, including clinical improvement and perioperative mortality.

Main Results:

• Minimally invasive intravascular approaches are generally recommended for IHPSSs, with exceptions for certain cases like patent ductus venosus.
• Percutaneous transvenous coil embolization demonstrates favorable outcomes.
• Clinical improvement is reported in over 80% of treated patients, with low perioperative mortality rates.

Conclusions:

• Shunt attenuation significantly improves long-term outcomes and liver function in patients with congenital portosystemic shunts.
• Percutaneous transvenous coil embolization is an effective and safe treatment for intrahepatic portosystemic shunts.
• Minimally invasive techniques offer a promising therapeutic strategy for managing complex congenital portosystemic shunts.
