By definition the liver hanging manoeuvre (LHM) means that a slip is passed between the liver parenchyma and the inferior vena cava. It was first published by Belghiti in 200l, and several changes in the indication as well as in the method have been published since then. In parallel, the anatomical and histological basis has been clarified for LHM, too. According to general consensus LHM increases safety and radicality of liver surgery. Initially LHM was applied for removal of huge tumours infiltrating the diaphragm. Authors worked out two modifications for LHM. Tumours / primary or secondary / in segment IVA are sometimes located in close proximity to the median hepatic vein and inferior vena cava , and the resectability of these tumors can determined by the hanging manoeuvre. Tumors in segment VII can be removed by partial resection of vena cava facilitated by LHM. Four patients with LHM are discussed, and based on this limited experience as well as the latest observations from relevant literature the authors claim that LHM increases the safety of resections from segment IVA and VII. Vascular infiltration of the vena cava is always a technical challenge, which can be suspected on preoperative imaging modalities, but in borderline cases only the intraoperative ultrasound and surgical judgment together with LHM would lead to the exact diagnosis and makes the resection possible.
