Baseline characteristics

Patient number	Age	Gender	Underlying condition	Baseline imaging findings
1	43	Male	Previous splenectomy with new-onset post-prandial pain. Initial attempt of catheter-directed thrombolysis failed	MPV and SMV thrombosis with cavernous transformation
2	64	Male	HCC and chronic PVT in anticipation for LT	Cavernous transformation of PV, cirrhosis, splenomegaly, esophageal varices
3	38	Female	Chronic PVT due to JAK2 mutation with history of unsuccessful trans-splenic PVR-TIPS	Occluded SV, extensive thrombus in the SMV, cavernous transformation of main, right, and left PVs
4	40	Male	PVT in the setting of JAK2 and factor V Leiden mutations with worsening post-prandial and extensive gastroesophageal varices	Main PV, SV, SMV could not be identified due to extensive thrombosis. Only IMV could be visualized

MPV, main portal vein; SMV, superior mesenteric vein; HCC, hepatocellular carcinoma; PVT, portal vein thrombosis; LT, liver transplantation; JAK 2, Janus Kinase 2; PVR-TIPS, portal vein recanalization–transjugular intrahepatic portosystemic shunt; SV, splenic vein; IMV, inferior mesenteric vein
