Radial Artery Access for Hepatic Chemosaturation: The First Description of Technical Feasibility.

Chemosaturation with percutaneous hepatic perfusion (CS-PHP; Hepatic CHEMOSAT® Delivery System, Delcath Systems Inc, Wilmington, Delaware) is an interventional radiology procedure that delivers high doses of melphalan, a chemotherapeutic agent, directly to the liver in patients with unresectable primary and secondary liver tumours. Traditionally, CS-PHP is delivered by arterial access via the femoral artery. However, there can be many risks and adverse effects associated with femoral artery punctures, such as retroperitoneal haemorrhage and haematoma formation. The monitoring and bed rest required following the removal of a femoral arterial catheter may also cause significant distress to patients as they remain immobile, potentially prolonging their stay in hospital. The radial artery is an alternative access point, with fewer reported adverse events and increased patient tolerance when compared with femoral access. This case report details the first reported use of Hepatic CHEMOSAT® therapy being delivered via the radial artery. Two patients received hepatic chemosaturation with no reported complications. This report demonstrates that access via the radial artery is a feasible alternative for the delivery of chemotherapy, which may reduce morbidity and the risks usually associated with femoral access.
