[Image navigated resection of liver segments].
Surgical treatment of liver malignancies improves survival rates and is often crucial for therapy in curative intention. Accurate resection margins are essential for long-term survival. Segmentorientated resection improves surgical results by systemic approach of tumour associated blood vessels. The application of navigational systems providing repetitive registrations of acquired data increased rate of resections with tumour free margins for complex and centrally located malignancies. Generation of preoperative three-dimensional models for surgical planning is required for preservation of unaffected liver tissue and to reduce mortality rate due to extend of resection. Three-dimensional ultrasound-based technique provides optimal visualization and orientation and consecutively accurate navigational resection of liver malignancies in daily routine compared to conventional liver surgery.
