چکیده (انگلیسی):

Background: Massive hemorrhage and the need for blood transfusion carry a high
rate of morbidity and mortality after hepatectomy. The aim of this study was to evaluate the
safety and potential benefit of infrahepatic inferior vena cava (IVC) clamping in hepatectomy
for tumors involving hepatocaval confluence.
Methods: We conducted a retrospective analysis of 113 consecutive patients who underwent
hepatectomy with infrahepatic IVC clamping (n Z 60, Group A) and without infrahepatic
IVC clamping (n Z 53, Group B) as the initial treatment for tumors involving hepatocaval con-
fluence.
Results: In Group A, central venous pressure reduced from 7.6
3.2 to 4.4
2.7 cm H2O
(p < 0.001). Patients in Group A experienced less blood loss (477.3
340.3 vs.
794.5
602.7 mL, p Z 0.001), fewer blood transfusion requirements (8.3% vs. 22.6%,
p Z 0.034), lower postoperative complications (40% vs. 60.4%, p Z 0.031), and shorter hospital
stay (10.7
2.2 vs. 12.9
4.8 days, p Z 0.008) than those in Group B.
Conclusion: Infrahepatic IVC clamping is generally effective and safe in controlling bleeding
during hepatectomy for tumors involving hepatocaval confluence.
