Background and objective: For tumors involving inferior vena cava (IVC), surgery with complete resection remains the first line treatment. Management of IVC after resection, either ligation without reconstruction or primary reconstruction, is debated. Our study aimed to evaluate type of venous reconstruction, anticoagulation management and morbidity.
Methods: A French single center database of patients who underwent partial or total circumferencial resection of the IVC for malignant disease was analyzed. Inclusion criteria were any oncologic procedure for a retroperitoneal neoplasm requiring concomitant resection of the IVC with or without venous reconstruction with prosthesis. Exclusion criteria were surgery before year 2000. Data were descriptive and reverse Kaplan Meier was used for follow-up calculation. The endpoints were the rate of prosthetic reconstruction, the use of anticoagulation and the post-operative outcomes.
Results: Fifty - one patients were included with a median duration of follow-up of 54.8 months. The majority of patients were men (56.9%). Median age of the population was 44.1 years. Most of the patients underwent surgery for primary testicular cancer and for sarcoma. Complete IVC resections were performed in 46 (90,2%) patients, 32 having a concomitant prosthetic replacement. Eight patients underwent aortic resection in the same operative time. Postoperative morbidity was 33.3%. Post-operative anticoagulation was done in 24 patients. At 1 month, four patients developed thrombosis in the prosthesis.
Conclusions: IVC resections are feasible and safe. Venous reconstruction and postoperative management were planned according to the preoperative imaging and intraoperative findings. We propose a decision-tree for peri-operative management and anticoagulation.
