5-Year Milestone: PKU First Hospital’s World-First "Block-and-Drain" Tech Defies Vascular Limits

🩺 [Challenge: Rare Vascular "Flooding"]
As of March 2026, PKU First Hospital marks a historic milestone: the patient who underwent the world’s first "Portal-end Embolization combined with TIPSS" has surpassed her 5th year of healthy survival.

Five years ago, this 73-year-old patient faced a fatal hepatic arterioportal fistula. High-pressure arterial blood flooded the portal vein, driving pressure to 53 mmHg (10x normal), causing catastrophic bleeding and refractory ascites.

⚖️ [Decision: A New Surgical Philosophy]
Conventional occlusion failed against such complex anatomy. The Expert Team innovated the "Block-and-Drain" concept:

Block: Precision "damming" from the portal side rather than a direct frontal assault on the artery.

Drain: Establishing a TIPSS shunt to provide a "spillway" for residual high-pressure flow.

🛠️ [Core: A Miracle Validated by Time]
The procedure achieved precise embolization and shunt placement. Bleeding stopped within 3 days; the patient resumed eating by day 5.

✨ [Summary: 5-Year Industry Insight]
This success proves the power of restructuring hemodynamic logic. 60 months of follow-up show a patent shunt and zero complications, confirming the long-term efficacy of this paradigm-shifting approach.
