Surgical resection of retrohepatic inferior vena cava leiomyosarcoma without vascular reconstruction: case report

Abstract Inferior vena cava leiomyosarcoma (IVCL) is a rare malignant mesenchymal tumor. Surgical treatment challenge because it must combine free surgical margins with vascular reconstruction, using prosthetic or autologous grafts, primary suture, simple ligation without vein reconstruction. The option possible thanks to the slow growth of tumor, allowing collateral venous circulation develop. We present case an IVCL treated radical resection patient was 48-year-old female abdominal pain in right upper quadrant, asthenia, and postprandial dyspeptic symptoms. Abdominal tomography revealed mass expansive formation located infrahepatic segment inferior reduced vessel lumen. During surgery, clamping did not provoke hemodynamic repercussions, suggesting sufficient formation. It decided perform entire portion retrohepatic ligate recovered complications.
