Inclusion criteria
Inclusion criteria: 1. Age >=18 years, regardless of gender; 2. Surgical procedure performed between January 2020 and December 2026; 3. Operation conducted by the Department of Hepatobiliary Surgery; 4. Intraoperative use of PTFE vascular grafts for various types of venous reconstruction, including interposition grafting, shunting, bypass, combined reconstructions, and hepatic outflow tract reconstruction (hepatic veins/retrohepatic inferior vena cava); 5. At least one postoperative contrast-enhanced CT or MRI examination completed for graft patency assessment; 6. Detailed operative documentation of reconstruction type, PTFE specifications, anastomotic technique, and intraoperative circumstances.
Exclusion criteria
Exclusion criteria: 1. Emergency procedures such as traumatic injuries or ruptured hemorrhage; 2. Isolated arterial reconstruction without venous system involvement; 3. Venous resection without reconstruction, such as simple splenic vein ligation; 4. Intraoperative abandonment of PTFE reconstruction due to technical reasons with conversion to alternative materials; 5. Loss of critical clinical data exceeding 30%, precluding confirmation of reconstruction type or graft material; 6. Absence of postoperative imaging follow-up precluding patency evaluation; 7. Early periprocedural mortality defined as death within 7 postoperative days, preventing graft function assessment; 8. Use of PTFE patch angioplasty alone without tubular reconstruction.
