Core photos of braided river delta and meandering river delta deposits: (a) Braided interdistributary bay deposit(FA2); (b) Braided distributary channel deposits(FA1) (location of cores a, b shown in Fig. , borehole W3 in Fig. b, 2620–2627 m depth; S1); (c) Subaqueous distributary channel deposits of braided river delta front: (FA3); (d) Estuary dam deposits of braided river delta front(FA4) (location of cores c, d shown in Fig. , borehole W4 in Fig. b, 2164–2180 m depth; S2); (e) Distal bar deposits of braided river delta front(FA5); (f) subaqueous interdistributary bay deposits of braided river delta front(FA6) (location of cores e, f shown in Fig. , borehole W2 in Fig. b, 2297–2289 m depth; S2); (g) distributary channel deposits of meandering river delta plain(FA7); (h) Distal bar deposits of meandering river delta plain (FA11); (i) subaqueous interdistributary bay deposits of meandering river delta plain (FA12) (location of cores g-i shown in Fig. , borehole W3 in Fig. b, 2044–2039 m depth; S3).

Well log correlation of depositional facies of sequences S1–S8. Note the transition from the braided river delta deposits at the bottom to the meandering river delta deposits and the transition from the delta plain deposits in the northwest to the pre-delta/slope deposits in the southeast at the uppermost region of the study area (location of the log correlation shown in Fig. b). The braided river deltiac systems (S1–S2) are characterized by thick bedded of pebbly coarse grained distributary channel deposits in the delta plain and subaqueous distributary channel deposits in the delta front. The meandering river delta systems (S3–S8) exhibit thin or no delta plain deposits and a middle-thick bed of middle-fine sandstone in the estuary dam deposits in the delta front. The location of the cores are shown in the W2, W3, W4 and W5 boreholes.

Patient with hepatitis B cirrhosis was diagnosed with hepatocellular carcinoma, refractory ascites, and esophageal gastric-fundus variceal bleeding. Patient underwent TACE after TIPS. A: Tumor lesion revealed by contrast-enhanced CT arterial phase (white arrow). B1: Obvious portal vein dilation (short white arrow) and gastric coronary vein varicosis (long white arrow). B2: Gastric coronary vein embolism (long black arrow) and distributary channel (short black arrow). C: Lodine oil deposited in the lesion after TACE, shown by CT (black arrow); ascites disappeared and distributary channel stent (white arrow). TACE: Transarterial chemoembolization; TIPS: Transjugular intrahepatic portosystemic shunt; CT: Computed tomography.
