🔍 Key Findings
- 40 dogs with congenital EHPSS were surgically treated using intraoperative transsplenic injection of agitated saline (TIAS) to assess full temporary occlusion.
- TIAS was successful in 38/40 dogs; the remaining 2 had additional shunting vessels not originally seen and required further identification/ligation.
- No intraoperative or postoperative complications occurred.
- TIAS allowed real-time confirmation of attenuation success using ultrasound-visible microbubbles.
- Median postoperative bile acids were 5 μmol/L (preprandial) and 25 μmol/L (postprandial).
- Long-term outcomes: 29/39 dogs had excellent, 10/39 had good outcomes; 3 dogs died unrelated to EHPSS.
- Technique is presented as a safe, quick, low-cost, accessible intraoperative assessment alternative to IOMP or SP.
