[Self-expandable metallic stent for use in venous occlusions].
Expandable metallic stent was successfully introduced to 5 patients including idiopathic obstruction of the hepatic portion of the inferior vena cava (1 case), superior vena cava obstruction from metastatic lymphnodes swelling (2 cases) and IVC obstructions from liver metastases or lymphnodes metastases (2 cases). The obstructions were 4-14 cm long in the case of venous obstructions due to lymphnodes metastases and 2 cm long in the case of idiopathic hepatic IVC obstruction. In all cases, the stents were introduced by using 12-16 Fr catheter percutaneously without any complications. The stent used was connected up to 7 pieces by using wire struts depending length of the obstructions. However the stents connected more than 5 pieces were difficult to advance through the catheter. The patients who had been treated with stents had been free from hazardous complications such as lower extremity swelling, and pain.
