Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Portal and Hepatic Vein Embolization

Experimental: Portal and Hepatic Vein Embolization - 3 patients per center over one year approximately 90 patients in total. Patients will undergo portal vein and hepatic vein embolization instead of only portal vein embolization.


Treatment: Surgery: Portal and Hepatic Vein Embolization
Procedure/Surgery: Combined portal vein embolization and hepatic vein embolization (PVE/HVE) • All techniques of PVE allowed (ipsi-lateral, contra-lateral, trans-splenic, all embolization agents except for ethanol alone) • All modifications of HVE allowed (venous occlusion umbrellas; trans-jugular, trans-hepatic, no use of vein glue to avoid lung embolization; staged approach allowed, but first PVE, then HVE and within 48 hours)
