Hepatic arterial chemotherapy: role of angiography.
Hepatic arterial infusion chemotherapy increases the hepatic concentration of chemotherapeutic agents without increasing systemic toxicity. Both percutaneous (most commonly left transbrachial) and surgical approaches are currently used for infusion catheter placement. Surgical catheter and pump placement has proved to be a reliable means of delivering drugs to the liver and has been commonly used for hepatic arterial chemotherapy for metastatic colorectal carcinoma. Meticulous angiographic evaluation of the hepatic vascular anatomy, its variations, and hemodynamics is necessary for correct catheter placement to achieve total liver perfusion without significant extrahepatic perfusion. Satisfactory hepatic perfusion should be documented before drug infusion. Hepatic arterial radionuclide flow imaging with technetium-99m-labeled macroaggregated serum albumin remains the most reliable means of assessing hepatic perfusion following catheter placement. Transcatheter techniques have been used to facilitate catheter placement, to prevent gastrointestinal drug toxicity, and to correct unsatisfactory perfusion following surgical catheter placement.

Computed tomography of leiomyosarcoma of the inferior vena cava.
Leiomyosarcoma of the inferior vena cava is a rare lethal malignancy. The authors report the seventy-sixth case of the literature and the sixth displayed by computed tomography. CT is presently the radiological modality of choice to localize the site and extension of the tumour, but a cavogram must also be obtained since it displays, much better than CT, the collateral veins and gives a synthetic longitudinal view of the tumour.
